Highlights

Smoking and Skin Damage

The skin of smokers ages more rapidly than the skin of non-smokers, even in areas of the body not exposed to sunlight, according to a 2007 study. Women in the study who smoked also had much lower levels of vitamin E secretions in their skin. Vitamin E may protect the skin from sun damage.
There may be an association between smoking and higher frequency of a type of acne (noninflammatory acne) in adult women, according to a European study.

Antioxidants and Your Skin

A study in the Journal of Nutrition found that a combination of antioxidants and trace elements supplementation raises the risk of skin cancer in women, but not in men.

Ultraviolet Radiation

Overall, exposure to ultraviolet radiation from sunlight (radiation referred to as UVA or UVB) accounts for about 90% of the symptoms of premature skin aging.
UVB primarily affects the outer skin layers. It is most intense when sunlight is brightest. People receive slightly over 70% of their yearly UVB dose during the summer.
UVA penetrates more deeply and efficiently. The intensity of UVA rays is less dependent on the time of day and season of the year than that of UVB rays.

Vitamin D

A report analyzing studies of vitamin D supplementation found that people who take vitamin D supplements live longer than those who do not. People who avoid sunlight are at risk for vitamin D deficiency.

Introduction

As you age, your skin undergoes progressive changes:

The cells divide more slowly, and the inner layer of skin (the dermis) starts to thin. Fat cells beneath the dermis begin to shrink. In addition, the ability of the skin to repair itself decreases with age, so wounds heal more slowly. The thinning skin becomes vulnerable to injuries and damage.
The deeper layer of the skin, which provides scaffolding for the surface skin layers, loosens and unravels. Skin then loses its elasticity (ability to stretch). When pressed, it no longer springs back to its initial position. Instead, older skin sags and forms furrows.
The sweat- and oil-secreting glands atrophy (waste away), leaving the skin without a protective layer of water and fat. The skin's ability to stay moisturized then decreases, and it becomes dry and scaly.
Frown lines (those between the eyebrows) and crow's feet (lines that spread from the corners of the eyes) appear to develop because of permanent small muscle contractions. Habitual facial expressions also form characteristic lines.
Gravity makes the situation worse, contributing to the formation of jowls and drooping eyelids. Eyebrows, surprisingly, move up as a person ages, possibly pulled up by forehead wrinkles.

Wrinkles can have a profound impact on self-esteem. The stigma attached to looking old is evidenced by the more than $12 billion Americans spend each year on cosmetics to hide the signs of aging. Our society places a premium on youthfulness, and age discrimination in the workplace, although illegal, has stalled many people's careers. Indeed, the emotional consequences of aging explain in large part why the cosmetics industry and plastic surgeons thrive.

The sun is the most important cause of prematurely aging skin (a process called photoaging) and skin cancers. Overall, exposure to ultraviolet radiation from sunlight (radiation referred to as UVA or UVB) accounts for about 90% of the symptoms of premature skin aging. Most of these effects occur by age 20:

Even small amounts of UV radiation trigger the processes leading to skin wrinkles.
Long-term repetitive exposure to sunlight adds up, and likely is responsible for the vast majority of unwanted consequences of aging skin, including basal cell and squamous cell cancers.
Intense exposure to sunlight in early life is an important cause of melanoma, a particularly aggressive type of skin cancer.

Initial Damaging Effects of Sunlight. Ultraviolet radiation penetrates the layers of the skin. Both UVA and UVB rays cause damage leading to wrinkles, lower immunity against infection, aging skin disorders, and cancer. They appear to damage cells in different ways, however.

UVB is the main cause of sunburns, and primarily affects the outer skin layers. UVB is most intense at midday when sunlight is brightest. People receive slightly over 70% of their yearly UVB dose during the summer. We receive only 28% during the remainder of the year. Window glass filters out UVB.
UVA penetrates more deeply and efficiently. The intensity of UVA rays is less dependent on the time of day and season of the year than that of UVB rays. For example, you receive only about half of your yearly UVA dose during the summer months, with the balance spread over the rest of the year. Window glass does NOT filter out UVA.

Both UVA and UVB rays cause damage to the body, including genetic injury, wrinkles, aging skin disorders, and skin cancers. Exactly how they cause this damage is not yet fully understood.

Processes Leading to Wrinkles. Even small amounts of UV radiation trigger the processes that can cause wrinkles:

Sunlight damages collagen fibers (the major protein that gives structure to the skin). Sunlight also causes damage to elastin, a protein in the skin that normally maintains springiness and strength of tissue beneath the skin.
In response to this sun-induced elastin accumulation, the body produces large amounts of enzymes called metalloproteinases. One study indicated that when people with light to moderate skin color are exposed to sunlight for just 5 - 15 minutes, the metalloproteinase levels in their body remain high for about a week.
The normal function of these metalloproteinases is generally positive -- to remodel the sun-injured tissue by producing and repairing collagen. This is an imperfect process, however, and some of metalloproteinases produced by sunlight actually degrade (break down) collagen. The result is an uneven formation (matrix) of disorganized collagen fibers called solar scars. Repetition of this imperfect skin rebuilding causes wrinkles.
An important event in this process is the over-production of oxidants, also called free radicals. These are unstable molecules that are normally produced by chemical processes in the body, a process called oxidation. Environmental damage, however, causes an overproduction of oxidants. Excessive amounts of oxidants damage the body's cells and even alter their genetic material. Oxidation may contribute to wrinkling by activating the specific metalloproteinases that degrade connective tissue.

In addition to sunlight, other factors may hasten the formation of wrinkles:

Cigarette Smoke. Smoking produces oxygen-free radicals, which accelerate wrinkles and aging skin disorders, and increase the risk for non-melanoma skin cancers. Studies also suggest that smoking and subsequent oxidation produce higher levels of metalloproteinases, the enzymes associated with wrinkles.

Air Pollution. Ozone, a common air pollutant, may be a particular problem for the skin. One study reported that it might deplete the amount of vitamin E in the skin. This vitamin is an important antioxidant.

Rapid Weight Loss. If weight loss occurs too rapidly, the volume of fat cells that cushion the face are also decreased before chemicals in the skin can react. This not only makes a person look gaunt, but can cause the skin to sag.

Blemishes

This report covers three types of blemishes: Liver spots, purpura, and seborrheic keratoses (or warts).

Liver spots (known as lentigos, or sun-induced or pigmented lesions) are flat brown spots on the skin. They are almost universal signs of aging. Occurring most noticeably on the hands and face, these blemishes tend to enlarge and darken over time. The extent and severity of the spots are determined by a combination of skin type, sun exposure, and age. These spots are harmless, but should be distinguished from lentigo maligna, which is an early sign of melanoma.

Liver spots or age spots are a type of skin change that are associated with aging. The increased pigmentation may be brought on by exposure to sun, or other forms of ultraviolet light, or other unknown causes.

Treating Liver Spots. Liver spots do not require treatment, although some people are distressed by their appearance. Treatments may include the following:

Trichloroacetic acid (a chemical peel).
Tretinoin (Retin A) alone or in a combination with Mequinol (Solagé). Tretinoin is related to vitamin A, and is also effective in treating wrinkles.
Gentle freezing with liquid nitrogen (cryotherapy).
Laser treatment. Specific lasers, such as the Nd:YAG, are effective in eliminating 80% of liver spots in one treatment. It may be more effective than cryotherapy and have fewer side effects.
Bleaching creams -- these are commonly available but are not as satisfactory as peels, and high concentrations can sometimes cause permanent loss of skin color.

Purpura occurs when tiny capillaries (blood vessels) break and leak blood into the skin. In older people, the condition (called senile or actinic purpura) is usually caused by fragile blood vessels. The capillaries appear as flat purplish patches. These patches are called petechiae when they are smaller than 3 mm (about a tenth of an inch). When they are greater than 3 mm, they are referred to as ecchymoses. Patients typically complain of a rash, which may appear reddish at first but gradually change color, turning brown or purple.

Treatment. Although there is no specific treatment for purpura, patients are advised to avoid trauma, including vigorous rubbing of the skin, which may be sufficient to damage the capillaries. Emollients that soften the skin may be helpful. Some doctors also recommend vitamin C, but its effectiveness is unproven.

Seborrheic keratoses, (also called seborrheic warts), are among the most common skin disorders in older adults. Their cause or causes are unknown. They usually appear on the head, neck, or trunk and can range in size from 0.2 - 3 cm (a little over an inch). They are well defined and appear to be pasted onto the skin, but their appearance can vary widely:

They can be smooth with tiny, round, pearl-like formations embedded in them.
They can be rough and warty.
They can be brown or black.

Seborrheic keratoses sometimes look like melanoma, since they can have an irregular border, but they are always benign. A dermatologist can tell the difference between them, although experts warn that melanomas may "hide" among these benign lesions and go unnoticed without close inspection. In general, seborrheic keratoses have a uniform appearance while melanomas often have a smooth surface that varies in height, color density, and shading. In some cases, keratoses may cause itching or irritation. They can be easily removed with surgery or freezing. Vitamin D3 ointment is also showing promise in clinical trials.

Risk Factors

Exposure to Sun in Childhood. It is estimated that 50 - 80% of skin damage occurs in childhood and adolescence from intermittent, intense sun exposure that causes severe sunburns. In spite of this now well-known effect, many people still believe that a tan in children signifies health. And even though many parents are concerned about sun exposure, they still rely too much on sunscreen and not enough on protective clothing.

The Elderly. Most people over 70 have at least one skin disorder. Many have three or four. Everyone experiences skin changes as they age, but a long life is not the sole determinant of aging skin. Family history, genetics, and behavioral choices all have a profound impact on the onset of aging-skin symptoms.

Of all the risk factors for aging skin, exposure to UV radiation from sunlight is by far the most serious. Indeed, the vast majority of undesirable consequences of aging skin occur in individuals who are repetitively exposed to the sun, including the following:

Outdoor workers, such as farmers, fishermen, construction workers, and lifeguards
Outdoor enthusiasts
Sunbathers
People who regularly attend tanning salons or use tanning beds (One study indicated that regular use significantly increases the risk for non-melanoma skin cancers. Fair-skinned women under age 50 may be at particular risk.)

Experts have devised a classification system for skin phototypes (SPTs) based on the sensitivity to sunlight. It ranges from SPT I (lightest skin plus other factors) to IV (darkest skin). People with skin types I and II are at highest risk for photoaging skin diseases, including cancer. It should be noted, however, that premature aging from sunlight can affect people of all skin shades.


Skin Type	Tanning and Burning History
I	Always burns, never tans, sensitive to sun exposure
II	Burns easily, tans minimally
III	Burns moderately, tans gradually to light brown
IV	Burns minimally, always tans well to moderately brown
V	Rarely burns, tans profusely to dark
VI	Never burns, deeply pigmented, least sensitive

The common belief is that women are at greater risk for wrinkles than men. Some evidence suggests, however, that given the same risk factors, men and women in the same age groups have comparable risks for skin photoaging. In a French study, the evidence of moderate-to-severe photoaging was observed in the following:

Twenty two percent of women and 17% of men ages 45 - 49
Thirty six percent of women and 38% of men by age 54
Nearly half of both men and women by age 60

Some studies report that men are more likely to develop non-melanoma skin cancers.

Heavy smokers are almost five times more likely to have wrinkled facial skin than nonsmokers, according to one study. The skin of smokers in areas of their bodies not exposed to sunlight also seems to age more rapidly, compared to non-smokers in the same age group, according to a 2007 study. In fact, heavy smokers in their 40s often have facial wrinkles more like those of nonsmokers in their 60s.

Studies of identical twins have found smokers to have thinner skin (in some cases by as much as 40%), more severe wrinkles, and more gray hair than their non-smoking twins. Even worse, cigarette smokers are more prone to skin cancers, including squamous cell carcinoma and giant basal cell carcinomas. A European study found an association between smoking and higher frequency of a particular type of acne in adult women. The study also found that women who smoked had much lower levels of vitamin E secretions in their skin. Vitamin E is an antioxidant that may help protect the skin from sun damage. [See In-Depth Report #41: Smoking.]

Prevention

The best long-term prevention for overly wrinkled skin is a healthy lifestyle.

Eat Healthy. A diet with plenty of whole grains, fresh fruits and vegetables, and the use of healthy oils (such as olive oil) may protect against oxidative stress in the skin. One study reported that people over age 70 years had fewer wrinkles if they ate such foods. Diet played a role in improving skin regardless of whether the people in the study smoked or lived in sunny countries. Benefits from these foods may be due to high levels of anti-oxidants found in them.

Exercise. Daily exercise keeps blood flowing, which brings oxygen to the skin. Oxygen is an important ingredient for healthy skin.

Reduce Stress. Reducing stress and tension may have benefits on the skin.

Quit Smoking. Smoking not only increases wrinkles, but smokers have a risk for squamous cell cancers that is 50% higher than nonsmokers' risk. Smokers should quit smoking to prevent many health problems, not just unhealthy skin.

The following are some daily measures for skin protection:

Don't wash your face too often with tap water. (Once a day is enough.) It strips the skin of oil and moisture. In addition, chlorinated water, particularly at high temperatures, poses special risks for wrinkles.
Wash your face with a mild soap that contains moisturizers. Avoid alkaline soaps, especially with deodorant.
Pat the skin dry and immediately apply a water-based moisturizer.
Always apply sunscreen, even if going outdoors for short periods.
Avoid drinking alcohol within 3 hours of bedtime. Alcohol increases the risk for leaks in the capillaries, which allows more water in and causes sagging and puffiness. Capillary leakage increases when one is lying down.
Lie on the back when sleeping. This helps offset the effects of gravity.

One of the most important ways to prevent skin damage is to avoid episodes of excessive sun exposure. The following are some specific guidelines:

Use sunscreens that block out both UVA and UVB radiation. However, do not rely only on sunscreen for sun protection. Wear protective clothing and sunglasses in addition.
Avoid exposure particularly from 10 a.m. to 4 p.m., when sunlight pours down 80% of its daily UV dose.
Avoid reflective surfaces, such as water, sand, concrete, and white-painted areas. Clouds and haze are not protective and in some cases may intensify UVB rays.
Ultraviolet intensity depends on the angle of the sun, not heat or brightness. So the dangers are greater the closer to the summer-start date. For example, in the Northern Hemisphere, UV intensity in April (2 months before summer starts) is equal to that in August (2 months after summer begins).
The higher the altitude the quicker one sunburns. One study suggested, for example, that an average complexion burns in 6 minutes at an altitude of 11,000 feet at noon, compared with 25 minutes at sea level in a temperate climate.
Avoid sun lamps and tanning beds or salons. They provide mostly high-output UVA rays. Some experts believe that 15 - 30 minutes at a tanning salon is as dangerous as a day spent in the sun. People should not be misled by advertising claims of "safe" tanning or promotions offering unlimited tanning.

Sunscreens. The use of sunscreens is complex, and everyone should understand how and when to use them. The bottom line is not that people should avoid sunscreens or sunblocks, but that they should always use them in combination with other sun-protective measures.

Protective Clothing. Wearing sun-protective clothing is extremely important and protects even better than sunscreens. Special clothing is now available for blocking UV rays and is rated using SPF ratings or a system called the UPF (ultraviolet protection factor) index, with 50 UPF being the highest. (According to one study, this is a very reliable indicator of protection.) The clothing is expensive, however. The following are some tips for everyone:

Adults and children should wear hats with wide brims. Even wearing a hat, however, may not be fully protective against skin cancers on the head and neck.
People should look for loosely fitted, unbleached, tightly woven fabrics. The tighter the weave, the more protective the garment.
Washing clothes over and over improves UPF by drawing fabrics together during shrinkage. An easy way to assess protection is simply to hold the garment up to a window or lamp and see how much light comes through. The less the better.
Everyone over age 1 should wear sunglasses that block all UVA and UVB rays.

Chemical Tanners. Some research suggests that melanin and dihydroxyacetone (DHA), the active ingredients in many self-tanning lotions, may help filter out UVA and UVB radiation and are therefore protective against sun damage More research is underway. A preliminary study funded by the National Cancer Institute found that people who received numerous daily injections of melanotan-1 (MT-1) before going in the sun or a tanning bed tanned more quickly and showed fewer signs of sun-related damage. MT-1 is a synthetic version of the hormone melanin, which helps produce the skin's natural pigment (color).

In choosing a sunscreen, look at the ingredients. Preparations that help block UV radiation are sometimes classified as sunscreens or sunblocks, according to the substances they contain. In general, sunscreens contain organic formulas and sunblocks inorganic formulas. However, the term sunblock is used less and less as sunscreens increasingly contain both kinds of ingredients:

Organic formulas contain UV-filtering chemicals such as octocrylene, octyl salicylate, homosalate, and octyl methoxycinnamate (block UVB), avobenzone-Parsol 1789 (blocks UVA), cinoxate, ethylhexyl p-methoxycinnamate (blocks UVB and small amounts of UVA), oxybenzone, benzophenone-3 (blocks UVA/UVB). People should look for a wide-spectrum sunscreen that contains combinations of these ingredients and filter both UVA and UVB. Of note: para-amino benzoic acid (PABA), once a popular ingredient, is now used infrequently. PABA may actually break down in the presence of UV exposure and release harmful oxidants. In addition, many people have an allergic reaction to it. Some products contain PABA derivatives, such as padimate O or octyl dimethyl PABA. It is not known if they have the same effects.
The Food and Drug Administration approved Anthelios SX in July 2006. This new sunscreen prevents sunburn and protects against ultraviolet A and B rays. The product contains ecamsule, an ingredient not previously marketed in the United States.
Inorganic formulas contain the UV-blocking pigments zinc oxide or titanium dioxide. Zinc and titanium oxides lie on top of the skin and are not absorbed. They prevent nearly all UVA and UVB rays from reaching the skin. Older sunblocks are white, pasty, and unattractive, but current products use so-called microfine oxides, either zinc (Z-Cote) or titanium. They are transparent and nearly as protective as the older types. Microfine zinc oxide may be more protective and less pasty-colored than microfine titanium oxide.

Inexpensive products work as well as expensive ones with the same ingredients. Unfortunately, there are still no standards for sunscreens, and even those claiming UVA protection may offer very little. In one study, the average UVA protection from a wide range of brands was only 23%. In fact, the average protection of brands not making the claim was 37%!

Organic formulas and inorganic microfine oxides do not protect against visible light, which is a problem for people who have light-sensitive skin conditions, including actinic prurigo, porphyria, and chronic actinic dermatitis. Inorganic sunscreens that protect against visible light and are still cosmetically acceptable are now available in Europe, but not yet in the US.

Calculating the SPF. The sun protection factor (SPF) on all sunscreen labels is a ratio based on the amount of UVB (not UVA) radiation required to turn sunscreen- or sunblock-treated skin red compared to non-treated skin. For instance, people who sunburn in 5 minutes and who want to stay in the sun for 150 minutes might use an SPF 30. The formula would be: 30 (the SPF number) times 5 (minutes to burn) = 150 minutes in the sun.

Protection offered by sunscreens may be classified as follows:

Minimal: SPF 2 to 11.
Moderate: SPF 12 through 29.
High: 30+. (Although some sunscreens claim SPFs higher than 30, the added protection at such higher levels is insignificant.)

SPF Levels by Age Group. Certain groups should have higher or lower SPFs depending on age and other factors:

Although sunscreens are safe in most toddlers and children, they should not be the first and only lines of defense. In fact, experts are worrying that by relying too much on sunscreen and not providing other protective measures, parents may actually be increasing their children's risk for melanoma. All young children should be well covered with clothing, sunglasses, and hats as the first line of defense against sunburn. Children should be kept out of the sun during peak sunlight periods. Sunscreens should not be used on babies younger than 6 months without consulting a doctor.
Older children and adults (even those with darker skin) benefit from using SPFs of 15 and over. Some experts recommend that most people should use SPF 30 on the face and 15 on the body.
Adults who burn easily instead of tanning and anyone with risk factors for skin cancer should use at least SPF 30.

Timing and Amount of Application. You should apply sunscreen or sunblock liberally as follows:

Adults should include sunscreen with a daily skin regimen, even if going outdoors for only a short time.
Apply a large amount to all exposed areas, including ears and feet. To achieve protection as indicated by the sunscreen's SPF, experts recommend half a teaspoon each for the head, neck, and each arm and a teaspoon each for the chest area, the back, and each leg.
Apply initially 30 minutes before venturing outdoors for best results. (This allows time for the sunscreen to be absorbed. Then reapply every 15 - 30 minutes while being in the sunlight.
Also reapply each time after exercise or swimming. (Choose a waterproof or water-resistant formula even if activities don't include swimming. Waterproof formulas last for about 40 minutes in the water, whereas water-resistant formulas last half as long.)
Insect repellents reduce sunscreen SPFs by up to one-third. Use higher SPFs and very liberal application when applying both.

Possible Hazards of Sunscreens, Sun Avoidance, or Both. When used generously and appropriately, sunscreen products and sun avoidance help reduce the severity of many aging skin disorders, including squamous cell cancers. There are certain concerns, however.

Sunscreen Use May Not Protect Against Basal Cell and Melanoma Cancers and May Even Increase the Risk. Although sunscreens help prevent squamous cell carcinomas and other skin disorders, sunscreens do not appear to provide protection against melanoma and some basal cell cancers. In fact, some studies have reported a higher association with sunscreen use and these skin malignancies, though not all studies report such negative results.

The reasons for this possible increased risk are unclear, though some theories include the following:

Until recently, many sunscreens blocked only or mostly UVB rays and not UVA, the more deeply penetrating rays now known to be especially dangerous. Past studies may not have reflected the effects of the broad-spectrum sunscreens now available, which block both UVA and UVB.
People who apply sunscreens may feel safe and stay out longer during high sun-exposure hours than is safe. Even if a person doesn't sunburn, UVA rays can still penetrate the skin and do harm.
People may not put on enough sunscreen. According to a 2002 study, people generally apply only 20 - 60% of the recommended amount, which can provide significantly less protection than the given SPF. (Of note, a 2003 study reported that when applied at the recommended amount, a broad-screen sunscreen prevents DNA damage from UV exposure. However, omitting it even once resulted in significant cell injury.)

Sunscreen Use May Increase the Risk for Health Problems Related to Sunlight Deficiencies. There is some major concern that underexposure to sunlight, due to the use of sunscreens or sun-avoidance measures, may produce other health problems, such as the following:

Vitamin D Deficiency. Vitamin D is found in only a few foods, such as fortified dairy products and fish, but it is produced in the skin in response to UVB sunlight. A medical literature review published in the journal Nutrition and Cancer reported that UVB rays may outshine dietary supplements for building the body's vitamin D reserves. Without an appropriate mix of diet and supplements, vigorous sun protection measures may increase a person's risk for developing vitamin D deficiency. Vitamin D is important for prevention of rickets, osteoporosis, and some cancers, including melanoma. People who need to avoid sunlight and whose diet is low in foods that contain vitamin D should check with their doctor about taking supplements. People with darker skin are at higher risk for deficiencies from sun protection than those with whiter skin. Note: vitamin D is toxic in high doses. Most doctors recommend 200 IU a day (for young adults) to 600 IU a day (above age 70). Doses up to 2,000 IU a day are considered safe. A report analyzing studies of vitamin D supplementation found that people who take vitamin D supplements live longer than those who do not. The researchers looked at 18 studies. They found that participants who received vitamin D supplements were, on average, 7% less likely to die during the study they were in, compared with those receiving "sugar pills."
Other Cancers. Although sunlight is implicated in skin cancers, it is also associated with lower risks for breast, prostate, ovarian, and colon cancers. Some protection against these cancers may be related to vitamin D production by sunlight.
Depression. Many people suffer from SAD (seasonal affective disorder), a form of depression that generally occurs in winter and is associated with exposure to less sunlight.

The bottom line is that some sunlight is important and even necessary for a healthful and high-quality life. Adults may benefit from daily moderate tanning (20 - 30 maximum minutes of exposure during lower-risk hours) over several days to slowly build up pigment in the skin.

Treatment

An increasing number of dermatology patients are looking for a way to improve the appearance of their skin. As a result, more and more products have become available to treat skin wrinkles and blemishes. From vitamins and supplements to exfoliants and chemical peels -- the options can be overwhelming. In some cases, more than one approach may be needed.

Antioxidants are substances that hunt oxygen-free radicals, the unstable particles that can damage cells. Free radicals may also cause sun damage and even skin cancers. Exposure to sunlight depletes antioxidants in the skin, and therefore they must be replaced.

Antioxidant ointments, creams, and lotions ("topical products") may help reduce the risk of wrinkles and protect against sun damage. Unlike sunscreens, they build up in the skin and are not washed away, so the protection may last. Selenium, coenzyme Q10 (CoQ10), and alpha-lipoic acid are types of antioxidants that come in topical form. Many are proving to be very beneficial for the skin.

Vitamin A. Vitamin A is important for skin health. UV radiation produces vitamin A deficiencies in the skin. Topical products containing natural forms of vitamin A (retinol, retinaldehyde) or vitamin A-related products called retinoids (tretinoin, tazarotene) may help repair skin damage due to sunburn and natural aging.

Tretinoin (Retin-A). Tretinoin (known commercially as Retin-A) is the only topical agent approved for treating photoaging and is available in prescription form (Avita, Renova, Differin). The June 2004 issue of Dermatology Surgery reported that tretinoin (0.25% concentration) was an effective and well-tolerated treatment for photodamaged facial skin. This drug produces a rosy glow and reduces fine and large wrinkles, liver spots, and surface roughness. It also may help prevent more serious effects of ultraviolet radiation. Patients may apply tretinoin to the face, neck, chest, hands, and forearms, and should do so at least twice a week. Noticeable improvement takes 2 - 6 months. Because Retin-A increases a person's sensitivity to the sun, patients should apply just a tiny amount at bedtime, and wear sunblock during the day. Patients should also avoid overexposure to the sun. Almost all patients experience redness, scaling, burning, and itching after 2 or 3 days that can last up to 3 months. In women who experience irritation, a daytime moisturizer or low-dose corticosteroid cream, such as 1% hydrocortisone, may help. There is some concern that overuse of high-dose tretinoin may cause excessive skin thinness over time. Studies now suggest that low concentrations (as low as .02%) of tretinoin can produce significant improvements in wrinkles and skin color, with less irritation than the higher doses.
Retinol. Retinol, a natural form of vitamin A, could not, until recently, be used in skin products because it was unstable and easily broken down by UV radiation. Stable preparations are now sold over the counter. In the right concentrations, retinol may be as effective as tretinoin, and studies indicate that it has fewer side effects. An animal study suggests that adding antioxidant creams (such as those containing vitamins C or E) may offer added protection against degradation of retinol, but not tretinoin. The Food and Drug Administration warns that over-the-counter retinol skin products are unregulated. The amount of active ingredients is unknown, and some preparations, in fact, may contain almost no retinol.
Tazarotene. Tazarotene (Tazorac, Zorac, Avage) is a retinoid used for acne and psoriasis. It has now been approved for treating wrinkles, skin discoloration, and blemishes due to photoaging. One short-term study suggested that it may be as effective as tretinoin and even slightly better at high doses. At such high doses, however, it can cause very severe irritation. Redness and peeling may be reduced by administering tretinoin first to get the skin acclimated. A randomized study of 562 patients with facial photodamage found that a daily application of tazarotene 0.1% cream resulted in a minimum 1 grade improvement in fine and coarse wrinkling, uneven skin color, pore size, skin roughness, and overall photodamage. More research is needed to determine if it produces any long-lasting significant benefits.

Warning: Pregnant women and those who may become pregnant should avoid any vitamin A derivative (a product related to vitamin A). For example, oral tretinoin causes birth defects, and women should avoid even topical Retin-A when pregnant or trying to conceive.

Vitamin C. Vitamin C, or ascorbic acid, is a very potent antioxidant. Most studies on the effects of antioxidants on the skin have used this vitamin. In laboratory studies, large amounts of vitamin C reduced skin swelling and protected immune factors from sunlight. It may even promote collagen production. Vitamin C by itself is unstable, but products that solve the delivery problem are now available (such as Cellex-C, Avon's Anew Formula C Treatment Capsules, Physician Elite, and others). More research is needed.

Antioxidants Under Investigation for Skin Care. Other antioxidants are also being investigated for their value in skin protection. Most available brands, however, contain very low concentrations of these antioxidants. In addition, they are also not well absorbed and have a short-term effect. New delivery techniques, however, may prove to offset some of these problems.

Vitamin E. Studies suggest that topical vitamin E, particularly alpha tocopherol cream (a form of vitamin E), decreased skin roughness, length of facial lines, and wrinkle depth. Studies on mice have also reported reductions in UV-induced skin cancer with its use.
Both green and black tea may provide some protection against skin cancers and photoaging. There is also some evidence that pomegranate and soy extracts may help rejuvenate aging skin.
Aloe, ginger, grape seed extract, and coral extracts contain antioxidants and are promoted as being healthy for the skin, although evidence of their effects on wrinkles is weak.

A small study found that taking vitamin C and E supplements by mouth -- at the same time -- may help reduce sunburn, although it doesn't work as well as sunscreen. Taking the vitamins separately did not have any effect. Vitamin C and E are also antioxidants.

One of the basic methods for improving skin and eliminating small wrinkles is exfoliation (also called resurfacing), which is the removal of the top layer of skin to allow regrowth of new skin. Methods for doing this run from simple scrubs to special creams to intensive peeling treatments, including laser resurfacing. People with darker skin are at particularly higher risk for scarring or discoloration with the more powerful exfoliation methods.

Abrasive Scrubs. Scrub gently with a mildly abrasive material and a soap that contains salicylic acid to remove old skin so that new skin can grow. The motion should be perpendicular to the wrinkles. Use textured material or cleansing grains with microbeads. Organic materials, such as loofahs or sea sponges, may harbor bacteria. Avoid cleansing grains that contain pulverized walnut shells and apricot seeds, which can scratch skin on a microscopic level. Cleansing grains with microbeads don't have sharp edges and remove skin without cutting it. Exfoliation using scrubs, however, can worsen certain conditions, such as acne, sensitive skin, or broken blood vessels.

Topical Alpha Hydroxy Acid and Similar Substances. Alpha hydroxy acids (AHA) ease the shedding of dead skin cells and may even stimulate the production of collagen and elastin. Their natural forms are:

Lactic acid (milk)
Glycolic acid (sugar cane)
Malic acid (found in apples and pears)
Citric acid (oranges and lemons)
Tartaric acids (grapes)

Most alpha hydroxy acid products contain glycolic acid. Skin care products are also made from polyhydroxy acids (PHAs) and beta hydroxy acids (BHAs). Research suggests that PHA products may cause less skin irritation than AHA or BHA products.

Acid concentrations in over-the-counter AHA preparations are 2 - 10%. One clinical study suggested that 8% concentrations showed modest skin improvement Some examples include Avon's Anew Intensive Treatment (8% glycolic), Pond's Age Defying Complex (8%), Elizabeth Arden's Alpha-Ceramid Intensive Skin Treatment (3 - 7.5%), and BioMedic's home product (10%). Prescription strength creams contain at least 12% glycolic acid, and glycolic acid peels of 30 - 70% concentration may be administered in a doctor's office at weekly or monthly intervals.

Response to AHA varies, and the treatment is not without risk, particularly in high-concentration products. Side effects from over-the-counter creams, prescription products, and professional AHA peels can include burns, itching, pain, and possibly scarring. Studies also suggest that AHA may increase susceptibility to sun damage, even at concentrations as low as 4%. Such effects can persist up to a week after a person stops using the product. Experts advise that people purchase products with AHA concentrations of 10% or less. Chemical peels of up to 60% are available without prescription on the Internet. Such concentrations are not recommended, except under a doctor's supervision. If any adverse effects occur, stop using the product immediately. Always avoid sunlight or use proper sun protection when using these products.

Copper Peptides. Certain copper-containing compounds may protect skin and help repair it. Note: copper is a toxic metal. When using products containing copper, buy only those that contain peptides (small protein fragments) that bind to copper. Most studies have been conducted on the copper peptide glycyl-l-histidyl-l-lysine:copper (II) or GHK-Cu. It is currently used in a number of products (such as CP Serum, Neutrogena's Visibly Firm, ProCyte's Neova).

Furfuryladenine. Furfuryladenine (Kinetin, Kinerase) is a naturally occurring growth hormone found in plant and animal DNA. It has antioxidant and anti-aging properties. Some small laboratory studies suggest that furfuryladenine may delay the onset and decrease the effects of aging on skin. However, there are no well-conducted human studies to support this suggestion.

Vitamin K. Microsponge-based vitamin K is said to clear bruises spider veins, and other small blood vessel damage. Vitamin K is important for blood clotting.

Moisturizers help prevent dryness, bruising, and tearing. They have no effect on wrinkles by themselves. Moisturizers should be applied while the skin is still damp. These products retain skin moisture in various ways:

Occlusives, such as petroleum jelly, prevent water from evaporating.
Humectants, including glycerin, act by pulling water up to the surface of the skin from deep tissues. People with oily skin generally should use the humectant type.
More powerful compounds, such as monolaurin (Glylorin), contain mixtures of fatty molecules (lipids), which may help restore the skin's natural barriers against moisture loss and damage.

Most moisturizers contain combinations of these compounds. They usually have other ingredients as well, such as alpha hydroxy acids, sunscreens, collagen, and keratin. Collagen and keratin leave a protein film and temporarily stretch the skin. They range widely in price, and a major consumer organization found little difference in general between the more and less expensive products.

The skin under the eyes is very thin and does not produce as much of the protective oils that keep skin soft and supple. Manufacturers market their under-eye gels as being able to reduce puffiness and dark circles. The creams typically work in one of two ways:

By temporarily constricting blood vessels to prevent the build-up of fluids
By firming the skin with an invisible film

Never rub the creams under the eyes, as this may cause more wrinkles to form. Instead, apply these products with a light tapping motion to stimulate the skin.

Cosmetics, if properly applied, can be surprisingly effective in camouflaging the signs of aging skin, including wrinkles and age spots. Moreover, they offer additional benefits by retarding water loss and providing a physical barrier to UV radiation. However, as women age, less is more.

Here are some suggestions for older women:

Moisturizers. Apply moisturizers before foundation. If reddish discoloration is extensive or the skin is sallow, tinted moisturizers may be helpful and can be worn alone or under foundation.

Foundations. Caking on make-up will cause cracks at the wrinkle lines and only increase the appearance of aging. Try to cover large areas of the face with a moderate-coverage foundation that has a matte or semi-matte finish. Facial powder reflects light and thus minimizes wrinkles, but people with dry skin should avoid it.

Correcting Color. When blemishes are especially prominent, applying color correctors under the foundation can be very effective:

Green neutralizers mask red lesions.
Yellow will camouflage dark circles and bruises.
Mauve (a purplish-pink color) helps neutralize sallow skin or yellowish blemishes.
A white, pearled base helps to minimize wrinkles.

Blushes. Blushes and color washes can help conceal the spidery network of dilated capillaries on the nose and cheeks. Powder blushes are preferred because they blend easily on top of foundation.

Eyes. Powder eye shadows applied on top of a moisturizer are better than cream-based shadows. Light-colored shadow, applied along the upper eyelid crease and above the iris (the colored part of the eye) is best for offsetting the appearance of deep-set eyes. You should then apply a slightly deeper shade of the same color to the lower part of the eyelid, and draw it out to the corner.

Lips. A lip-setting cream or facial foundation should be applied before lipstick to help prevent it from bleeding into surrounding wrinkles. Try using a stiff bristle brush instead of a lip pencil. The brush will help keep the lipstick on and prevent bleeding. (Some women use the pencil itself for the full lip, which gives color but appears natural.) Some make-up artists recommend cream lipsticks instead of matte.

The Food and Drug Administration (FDA) does not regulate herbal remedies and dietary supplements. In other words, the manufacturers and distributors of such products do not need FDA approval to sell their products. In addition, any substance that affects the body's chemistry can, like any drug, produce side effects that may be harmful. There have been numerous reported cases of serious and even deadly side effects from herbal products.

Overexposure to sunlight can damage skin. The following natural remedies may cause extra sensitivity to light (photosensitivity):

St. John's wort (Hypericum perforatum) is a popular herbal remedy for depression. People who are sensitive to light should not use it. A case report suggests that St. John's wort may cause skin reactions in patients who have laser treatment.
Kava (Piper methysticum) is an herb used to calm nerves and reduce stress. In addition to photosensitivity, it can cause liver damage.
Yohimbe (Pausinystalia yohimbe) is used to treat erectile dysfunction. Both the herb and the pharmaceutical drug (yohimbine) can cause sensitivity to light.
Essential oils in many botanical aromatherapy products can trigger photosensitivity. Avoid citrus oils (grapefruit, lemon, lime, and orange) as well as bergamot, cumin, ginger, and angelica root oils.

Resurfacing Treatments

There are many choices for skin resurfacing (also called exfoliation), and the patient must consider several different factors that affect the choice. Resurfacing can achieve the following:

Removal of abnormal tissue and rough skin
Stimulation of new skin growth
Stimulation of collagen and elastin production

In addition to determining the skill of the surgeon and the safety of the procedure, the patient must discuss the desired depth of the resurfacing and the capability of each procedure to reach this depth safely. All resurfacing procedures require a healing period afterward, during which the skin is red and sensitive. The deeper the procedure, the higher the risk for complications, including delayed healing, infection, loss of pigment (skin color), and scarring.

If you make the decision to pursue intensive treatments, consider the following factors, among others, and discuss them with your dermatologist or plastic surgeon:

The ability of the procedure to safely reduce wrinkles
The ease and safety record of the procedure
The skill of the doctor
The length of recovery
Possible complications
How long the benefits will last

A person's age also helps determine the procedure:

For people in their 30s, a simple chemical peel is sufficient.
After age 40, people may benefit from collagen or fat implants.
At age 50 and over, plastic surgeons recommend laser resurfacing and customized treatments for individual needs.

In older individuals, combination procedures may be beneficial. Some examples include the following:

Laser surgery may be used for deep lines (such as those around the mouth) and chemical peels used over the rest of the face.
For enhancing the eye by correcting droopy eyelids, bags, and a "sinking" brow, combinations of eyelift (blepharoplasty), Botox, and laser resurfacing may be used.

Chemical peels, also known as chemosurgery, help restore wrinkled, lightly scarred, or blemished facial skin. Much like chemical paint strippers, chemical peels strip off the top layers of skin, and new, younger-looking skin grows back. The procedure is very effective for the upper lip but cannot be performed around the eyes. Partial peels are often done in conjunction with a face-lift. Combinations of the topical antioxidants, such as tretinoin and vitamin C, along with a chemical peel, may be particularly effective.

The Procedure.

A dermatologist applies chemicals to the skin. They include trichloroacetic acid, high concentrations of alpha hydroxy or beta hydroxy acids, or combinations of all three.
In some cases, tretinoin or alpha hydroxy is applied 4 - 6 weeks before, and starting one day after, the peel. Such treatments can enhance the effects of a peel and reduce the risk of discoloration in people at risk for this complication. Tretinoin is being tested as a chemical peel.
A crust or scab generally forms within 24 hours after surgery. You can remove this scab by gently cleansing with soap and water.
The skin takes 6 - 7 days to heal.
After the scab disappears, the visible skin is deep red but gradually lightens as it regenerates.

Complications. Complications include white heads, cold sores, infection, scarring, numbness, and permanent discoloration, particularly in people with darker skin. Refinement of chemical peel techniques are now permitting doctors to reach deeper skin, improvements which make it easier to apply peels to non-facial skin and to individuals with darker skin.

Dermabrasion affects deeper layers of skin than chemical peels, and may be useful for removing disfiguring marks, such as deep acne scars or deep wrinkles. As with chemical peels, it is effective for wrinkles on the upper lip and chin, and cannot be used around the eyes. Some doctors prefer dermabrasion to lasers for skin surfacing of people with darker skin colors.

Standard Dermabrasion. Standard dermabrasion uses a rotating brush that removes the top layers of a person's skin. As with chemical peels, dermabrasion selectively strips away the upper layers of skin, leaving the underlying skin layers exposed. Similar to chemical peels, after the procedure, the treated skin oozes and forms a scab, a reaction that looks and feels uncomfortable, but only temporary. Postoperative care is similar for both procedures.

Microdermabrasion. A gentler variation called microdermabrasion uses very tiny crystals to polish the skin and a vacuum technique to remove them. It has largely replaced the older dermabrasion, and, in fact, was the fourth most common non-surgical cosmetic procedure performed in 2005, with over a million done. Results are similar to light chemical peels. Patients can have this procedure done on their lunch hour and return to work. Only mild redness occurs after treatment, although for best results five or six repetitive treatments are needed every 1 - 2 weeks. To date, overall patient satisfaction has been very high.

Lasers are currently the most effective exfoliation tools for eliminating wrinkles. Their unique advantages over other resurfacing methods are their ability to tighten the skin. A successful procedure can make patients look 10 - 20 years younger, and the results can last up to 10 years.

The procedure is most beneficial for the following areas:

It is best around the mouth and eyes. Recent evidence suggests CO₂ lasers may be even better than dermabrasion for the upper lip.
It is slightly less beneficial for the area around the nose.

Used alone, current laser therapy does not eliminate crow's feet, broken blood vessels, or dark circles under the eye. The evidence of the effects of lasers on acne scars is incomplete.

Standard laser dermabrasion is too harsh for thinner skin layers, such as on the neck. Newer and gentler laser techniques, however, stimulate collagen without removing skin layers, and may prove to be useful for necklines.

The Laser Resurfacing Procedure. In general the procedure works in the following way:

Laser pulses penetrate the skin quickly, vaporizing water and surface skin without damaging the deeper layers, allowing new top skin to grow.
In addition, the laser delivers enough heat to shorten collagen fibers, restoring some elasticity to the skin.

Choice of Lasers. The lasers used depend on skin type and severity of the condition. Some of the more common laser types are:

The carbon dioxide (CO₂) laser. This is the most powerful laser treatment and is used for deep wrinkles and skin imperfections. People who have had silicone injections should not have CO₂ procedures, which can burn and scar the skin over the implanted area.
The erbium: YAG (Er:YAG). This laser is gentler than the CO₂ laser, and is effective for mild wrinkles and for providing a smooth skin texture. It has a shorter recovery time. Some experts have even found the YAG laser as effective in removing deep wrinkles as CO₂ when used to sufficient depth. A variable pulse YAG laser can shift between pulses that destroy skin tissue to those that heat the skin. This process effectively resurfaces the skin with fewer side effects than CO₂ laser therapy.
Pulsed dye laser. Pulsed dye laser uses yellow light, which is easily absorbed by hemoglobin, the molecule that gives blood its red color. Pulsed dye laser treatments are used to treat skin blemishes that are due to blood vessel abnormalities, such as port-wine stains.

A gentle laser procedure called non-ablative laser resurfacing (NLite), also called photorejuvenation, is now approved for the treatment of all facial wrinkles. The procedure uses light energy to gently stimulate new collagen, and possibly elastin production, without removing the skin tissue itself. Its effects are less pronounced than those of other laser procedures. However, because it does not injure the external layers of skin, it can be used on delicate skin areas, such as the neck and around the eyes. It also causes very little irritation afterward.

Some surgeons are using combination techniques that employ more than one laser technology in one session, to achieve different effects. For example, one combination technique uses CO₂, YAG, pulsed-dye laser, and one other laser technology to both improve wrinkles and clear under-eye dark circles and acne scarring. Pretreatment with botulinum (Botox) injections before laser resurfacing significantly improved the treatment of crow's feet in one study.

Post-Procedure Recovery. The procedure itself is relatively painless, but the redness and irritation that occur during the healing process can be severe. Non-ablative laser resurfacing does not have the same severe after-effects as other laser treatments. For 8 - 9 days, the face looks skinned and swollen, and requires continuous moisturizing. Some doctors suggest that people with very sensitive skin, who cannot tolerate the necessary medications and lubricants, should avoid laser resurfacing. Redness and sensitivity can persist for 1 - 4 months. The patient must stay out of the sun as much as possible during this time, and should always avoid sunbathing and damaging their skin again. Early research suggests that silicone dressings may reduce post-procedure pain and crusting.

Complications. Scarring and infections can occur in about 1% of procedures. The risk of complications depends on the experience of the surgeon. People with a history of herpes simplex may experience flare-ups of fever, facial pain, and flu-like symptoms for 5 or 6 days after the procedure. In addition, people with darker skin may wish to avoid the procedure, because it can cause unpredictable and dramatic lightening of the skin.

A new skin rejuvenation technology, called Plasma Skin Resurfacing, or Portrait Plasma, was introduced in February 2005. The technology uses plasma energy (heat and light energy) to rejuvenate the skin from the deeper layers outwards. While new skin regenerates, the outer layers of the skin act as a natural bandage. When the outer layers peel off in the week after treatment, the new skin emerges. The process prevents or minimizes the raw appearance that follows laser treatments. This system uses radio waves to "excite" nitrogen gas, resulting in the release of energy. According to the manufacturer, skin regeneration using the Portrait Plasma system is rapid, and satisfaction with the procedure appears high. Long-term follow-up studies are not available yet for this new method. In 2006, the Food and Drug Administration approved this method for the treatment of wrinkles on other areas of the body, besides the face.

Cold Ablation. Cold ablation, called coblation for short, delivers saline (salt water) to the skin, through which a cool electric current is passed. A subsequent reaction heats and vaporizes the top shallow layer of skin. The procedure is very specific and appears to minimize any damage to other areas of the skin.

Radiofrequency Resurfacing. A promising technique uses low radiowave energy to resurface the skin. Preliminary research indicates that this procedure may eventually be as effective as laser surgery in reducing severe wrinkles around the eyes and mouth, with minimal pain and a shorter recovery time. In one study, one radiofrequency treatment with only a skin anesthetic resulted in tighter facial skin for 14 out of 15 patients within 12 weeks. All but one patient returned to normal activity immediately afterward. A small clinical trial published in Dermatology Surgery found that a noninvasive radiofrequency technique called NARF safely and effectively improved drooping lower eyelids.

Intense Pulsed Light. Intense pulsed light (IPL) uses filters to deliver different wavelengths of light. Doctors use it to treat a number of photoaging skin problems, and it appears to have long-term effects. Typically, four to six treatments are performed over a four-month period. Each treatment takes 15 - 20 minutes. Unlike laser light, which uses one color wavelength (such as green or red), intense pulsed light starts with a full spectrum of light. It then allows the doctor to selectively block off specific wavelengths, depending on how shallow or deep the procedure should go. IPL machines are less expensive and safer than lasers.

Implant Procedures

Implants, also called injectable fillers, are becoming a common means of erasing wrinkles and folds. Several materials are being used for deep wrinkles, depression under the eyes, lip enhancements, and acne scars.

After being banned from the market in 1992, silicone is making a comeback in research settings as a potential permanent wrinkle eraser. Scientists are looking into a new microdroplet technique (the use of very small drops) combined with purified silicone as a way to eliminate any danger. The past problems with silicone occurred when it was mixed with a foreign substance, like mineral oil, or when it was injected in large doses.

Most implants to date, however, are not completely satisfactory. Collagen implants and biologic fillers from animal, bacterial, or human sources do not provide long-lasting benefits. Synthetic fillers are permanent but may cause an allergic reaction, which can lead to chronic problems. Such reactions are rare, but they can be painful and unattractive.

The U.S. Food and Drug Administration (FDA) approved the Juvéderm product line in June 2006. Juvéderm is an injectable treatment of moderate-to-severe facial wrinkles and folds. Juvéderm products are gels made from hyaluronic acid. They are injected into the face. Doctors report good results after a single treatment with Juvéderm, and the results last for at least 6 months.


Name and Material Used	Procedure	Specific Areas Affected	Benefits	Drawbacks
Collagen implants. Collagen is the protein that forms the structures in the body (such as skin, bones, cartilage). The implant procedure has typically used bovine (cow) collagen. A form of human collagen (CosmoDerm, CosmoPlast) has now been approved.	Injected into target wrinkles with needle and syringe. Several weeks after injection, cow collagen breaks down and is replaced by newly created human collagen.	Wrinkles around the eyes and mouth. It is used to give lips greater fullness.	Very simple with faster recovery than many other implant techniques.	Wrinkles form again, and require repeat treatments 3 - 12 months later. Rarely, severe allergic reactions occur. Should not be used by children, pregnant women, and people with a history of autoimmune disease.
Microlipoinjection. Fat tissue from the patient's own thigh or abdomen.	Injected into target wrinkles with needle and syringe.	Deep wrinkles around the nose and mouth, folds in the forehead, and wrinkles on the hands.	No allergic or immune reaction because substance is patient's own fat.	Body eventually absorbs the fat, resulting in a need for multiple injections. Some studies suggest that 70% of the fat may still be in place after at least a year.
Gore-Tex. Highly porous (full of tiny holes) and inert (not chemically active) synthetic material.	Requires some surgery. Tiny patches are inserted under the skin to fill out wrinkles. Skin cells and blood vessels pass through the porous material easily, reducing the risk of severe irritation.	Deep wrinkles.	Material does not break down.	Possible scarring from surgical procedure. Allergic reactions are rare but can occur even with chemically inactive materials.
Artecoll. Contains PMMA, or polymethylmethacrylate, an inert substance, enclosed in tiny droplets of natural collagen.	Material is injected. Body absorbs collagen. PMMA remains and stimulates new collagen growth.	Deep wrinkles.	Although part of the implant is a natural collagen implant, it does not degrade as quickly as a full collagen implant.	Repeat treatments may still be needed. Possible allergic reaction.
Hyaluronic acid. Natural (non-animal) substance acts like a molecular sponge to absorb water. The FDA approved Restylane in 2003, Captiva, Hylaform-Plus, and Hylaform in 2004, and Juvéderm in 2006.	Gel is injected under the skin.	Moderate-to-severe wrinkles.	Low risk for allergic reaction. May last longer than cow collagen.	Repeat treatments needed.
Poly-L-lactic acid. Synthetic polymer. Approved in US as Sculpta. Approved in other countries as New-Fill.	Material is injected under the skin.	Approved in U.S. only for patients with facial fat loss due to HIV. Approved in other countries for wrinkles.	Low risk of allergies. Treatment effects can last 18 - 24 months.	Doctors require special training.

The popularity of Botox injections has skyrocketed in the United States. Between 2004 and 2005, the number of procedures performed jumped 16 percent. Botox injection was the number one non-surgical cosmetic procedure in 2005, with more than 3.2 million injections. Botulinum, the deadly toxin found in uncooked foods, is also a powerful muscle-relaxant. Tiny amounts of a purified form (Botox) are injected into wrinkles to relax the surrounding muscles. It may benefit forehead and frown lines, crow's feet, lower eyelids, lines on the side of the nose, and the area between the upper lip and the nose. It is also useful for treating involuntary muscle movements that can occur after a face-lift.

The injections need to be repeated every few months, since the effects wear off. The treatment decreases the ability to frown or squint and may cause the corners of the mouth to turn down. When used for areas around eyes, it produces a rounder appearance afterward, which patients should be aware of before they undertake the procedure.

The drug does not cross the blood-brain barrier, and, to date, the only side effects are temporary muscle weakness near the injection site. Although there have been some reports that Botox can reduce migraine and tension headaches, Botox also causes headaches in about 1% of cases. In some cases, the headaches can be very severe and long lasting (from 8 days to a month). Some researchers suggest that either a contaminated batch of Botox or a specific injection technique may be the cause, but additional investigation is needed.

Plastic Surgery

In 2005, there were over 2.1 million cosmetic surgeries, up 1% from the year before. Most of these surgeries were liposuction and breast surgeries. However, over 200,000 each of eyelid and nose surgeries were performed. Facial plastic surgeries range from being fairly minimal, such as a brow lift, to a full face-lift.

Several face-lift procedures (called rhytidectomies) are available. Face-lifts can provide individuals with a more youthful look. The degree of improvement, however, depends on many factors, including age, bone structure, skin type, and personal habits, such as smoking and sunbathing.

The Procedure. When a face-lift is a relatively simple procedure, it can take about 2 hours under local anesthetic in a doctor's office. Complicated face-lifts are done under general anesthesia in a hospital and can take 3 - 6 hours. The face-lift procedure may be one of the following:

Superficial musculoaponeurotic system (SMAS) is the most common face-lift procedure. The surgeon makes an incision at the hairline and separates the skin from the underlying tissue and muscles. The muscles are tightened and excess fat and tissue, such as fat under the chin and neck, are removed.
The endoscopic subperiosteal or subgaleal face-lift is a less invasive surgical technique. The surgeon raises facial structures rather than cutting away flaps of skin. Only a few half-inch incisions are made, and scarring is minimal. Not all individuals are candidates for this procedure, however.

Neither SMAS nor the endoscopic version is effective for the middle part of the face, particularly the deep lines (naso-labial folds) that run down from the nose beside the mouth. Some time after the SMAS face-lift, the upper face begins to age again while the lower area keeps its shape, causing the face to look imbalanced. Researchers are looking at other approaches, such as one called composite face-lift, that lift most muscles in the face.

Recovery Process. Recovery normally lasts from several weeks to several months. Swelling and discoloration are common. Some patients report tingling or numbing sensations after surgery. These sensations generally decrease as damaged nerves regenerate.

Complications. A face-lift is not without risks. A postsurgical hematoma is a collection of blood that can occur after a face-lift. In one study, major hematomas occurred in 2.2% of patients and minor hematomas in 6.65% of patients. They generally develop within 2 weeks of the surgery and require draining. Even minor hematomas need fast treatment to prevent greater complications. Such complications can include infection, changes in skin color, fluid buildup, and prolonged recovery time.

Other less common complications may include the following:

Infection
Excessive bleeding
Imbalanced facial muscles
Delayed healing
Scarring
Permanent injury to the nerves that control facial movements

These complications are rare, particularly with a skilled surgeon, but the more complex the face-lifts, the greater the risk.

Blepharoplasty. Blepharoplasty is the primary surgical procedure for eye lifts. Results usually last 5 -10 years. Although simple, it has potential complications, including permanent difficulty in closing the eyes or making a stern expression. Newer techniques, however, are preventing this complication. Assuming the surgeon is experienced, laser surgery is now preferred to the standard surgical scalpel approach. Laser surgery reduces bleeding and bruising, and both the operation and recovery are faster. Temporary blurred or double vision is common. More serious complications include infection, bleeding, dry eyes, difficulty in closing the eyes, and pulling down of the lower lids. Rare cases of blindness have been reported.

Transconjunctival Upper Blepharoplasty. An innovative procedure called transconjunctival upper blepharoplasty removes fat from the membrane that lines the eyelids (the conjunctiva) and is an effective technique for treating both the upper and lower eyelids. Unlike traditional blepharoplasty, this procedure does not cause scarring in the nasal area. In patients who have scars from previous surgeries, transconjunctival removal of fat can also make existing scars less obvious. Long-term side effects and effectiveness of this procedure have not been studied.

Laser Liposculpture and Platysma Resurfacing. A procedure called laser neck and jowl liposculpture and platysma resurfacing may prove to be an alternative to face-lifts. The procedure requires only a one-inch incision under the chin and removing excess fat. After the fat is removed, the surgeon tightens the platysma, the thin muscular sheet under the skin of the neck, which improves the shape of the neck. Only local anesthetic is needed, and the patient can return to normal activities in 2 days. The patient's skin should be elastic enough to be able to reform without sagging.

Symptoms of Periodontal Disease

Symptoms of periodontal disease include red and swollen gums, persistent bad breath, and gum recession and loose teeth. Smoking, certain types of illnesses (diabetes), older age, and other factors increase the risk for periodontal disease. If you have periodontal disease, your dentist may refer you to a periodontist, a dentist who specializes in treating this condition.

Practice Good Dental Hygiene

Consistent good dental hygiene can help prevent gingivitis and periodontitis. The American Dental Association recommends that everyone:

Brush twice daily with a fluoride toothpaste (be sure to replace toothbrushes every 3 - 4 months).
Clean between the teeth with floss or an interdental cleaner.
Eat a well-balanced diet and limit between meal snacks.
Have regular visits with a dentist for teeth cleaning and oral examinations.

Mouthwashes

In 2007, the American Dental Association stated that antimicrobial mouthwashes may provide additional oral health benefits for preventing and reducing gingivitis and plaque. However, they are not a substitute for daily brushing and flossing.

Research

Intensive treatment of periodontal disease may help reduce inflammation and improve blood flow throughout the body, according to a small study published in 2007 in the New England Journal of Medicine. In the study of patients with severe periodontitis, intensive treatment ultimately resulted in improved endothelial function. Poor endothelial function is associated with increased risk for atherosclerosis and heart disease. Researchers are investigating the connection between periodontal disease and heart disease, and whether treatment of periodontal disease can reduce heart disease risk.

Introduction

Periodontal disease refers to a group of problems that arise in the sulcus, the gap between the gum and the tooth.

The part of the mouth that consists of the gum and supporting structures is called the periodontium. It is made up of the following parts:

Gum (gingiva). When healthy, the gingiva is pale pink, firm, and does not move. It has a smooth or speckled texture. The gingival tissue between teeth is shaped like a wedge.
The space between the gum and tooth, called the sulcus
Root surface (the cementum)
Connective tissue
Bone. The crest of the supporting bone, which can be viewed on x-rays, is normally 2 mm below the point where the crown of the tooth meets the root (the cementoenamel junction).

The structure of the tooth includes dentin, pulp and other tissues, blood vessels, and nerves imbedded in the bony jaw. Above the gum line, the tooth is protected by the hard enamel covering.

Periodontal diseases are generally divided into two groups:

Gingivitis, which causes lesions (wounds) that affect the gums
Periodontitis, which damages the bone and connective tissue that supports the teeth

The process starts with bacteria. Even in healthy mouths, the sulcus is teeming with bacteria, but they tend to be harmless varieties. Periodontal disease develops usually because of two events in the oral cavity: an increase in bacteria quantity and a change in balance of bacterial types from harmless to disease-causing bacteria. These harmful bacteria increase in mass and thickness until they form a film called plaque.

In healthy mouths, plaque itself actually provides some barrier against outside bacterial invasion. When it accumulates to excessive levels, however, plaque sticks to the surfaces of the teeth and adjacent gums and causes cellular injury, with subsequent swelling, redness, and heat.

When plaque is allowed to remain in the periodontal area, it transforms into calculus (commonly known as tartar ). This material has a rock-like consistency and grabs onto the tooth surface. It is much more difficult to remove than plaque, which is a soft mass.

The most important component leading to the disease process, however, is the body's persistent immune response to the bacterial plaque. Specific immune factors are released that cause inflammation and damage that eventually destroys the support structures and bone and can lead to tooth loss.

Gingivitis is an inflammation of the gingiva, or gums. Is nearly always chronic, but an acute form infrequently occurs.

Chronic Gingivitis. Ordinary chronic gingivitis affects over 90% of the population. It is characterized by tender, red, swollen gums that bleed easily and may be responsible for bad breath (halitosis) in some cases. Treatment is very effective if initiated early in the course of gingivitis. Without good management, however, the problem can progress.

Periodontitis is characterized by the following:

Gum inflammation, with redness and bleeding.
Deep pockets (greater than 3 mm in depth) form between the gum and the tooth.
Loose teeth, caused by loss of connective tissue structures and bone.

Gingivitis precedes periodontitis, although it doesn't always lead to this more severe condition. In fact, some experts believe it is an entirely different disease. There are different categories of periodontal disease, including:

Chronic Periodontitis. Chronic periodontitis (also referred to as adult periodontitis) may begin in adolescence as a slowly progressing disease that becomes clinically significant in the mid-30s and continues throughout life. Some experts question whether it is a chronic, unrelenting condition and instead suggest that it waxes and wanes depending on the response of the immune system.

Aggressive Periodontitis. Aggressive periodontitis (also referred to as early onset periodontitis) often occurs in young people. It is subdivided according to whether it begins before or after puberty. Immune deficiencies and a genetic link have been shown to be possible factors for all types of aggressive periodontitis. If the condition is localized and treated, the outlook is positive. People with severe and widespread aggressive periodontitis are at high risk for tooth loss.

Periodontitis that occurs before puberty is very rare. It begins with the eruption of primary teeth in the first year and causes severe inflammation and bone and tooth loss.
Juvenile periodontitis begins at puberty and is defined by severe bone loss around the first molars and incisors. It is more common in girls than in boys. The clinical signs -- such as inflammation, bleeding, and heavy plaque accumulation -- are not present in this relatively rare disease. The treatment is the same as in chronic periodontitis.
Rapidly progressive periodontitis occurs in the early 20s to mid-30s. Severe inflammation and rapid bone and connective tissue loss occur, and tooth loss is possible within a year of onset.

Disease-Related Periodontitis. Periodontitis can also be associated with a number of systemic diseases, including type 1 diabetes, Down syndrome, AIDS, and several rare disorders of white blood cells.

Acute Necrotizing Periodontal Disease. Acute necrotizing periodontal disease is an acute infection in the gums. It is characterized by:

Black, dead tissue (necrosis)
Spontaneous bleeding
Rapid onset of pain
Bad odor
Blunted gum tissue (tissue is normally cone-shaped)

Stress, poor diet, smoking, and viral infections are predisposing factors for this acute necrotizing periodontal disease.

Symptoms

In general, symptoms progress over time and include:

Red and Swollen Gums
Gum Bleeding. Bleeding of the gums, even during brushing, is a sign of inflammation and the major marker of periodontal disease. One exception is juvenile periodontitis, in which symptoms are mild or even absent. It should be noted that the gums of smokers with periodontal disease tend to bleed less than nonsmokers.
Bad Breath. Debris and bacteria can cause a bad taste in the mouth and persistent bad breath.
Gum Recession and Loose Teeth. As the disease advances the gums recede, and supporting structure of bone is lost. Teeth loosen, sometimes causing a change in the way the upper and lower teeth fit together when biting down or a change in the fit of partial dentures.

Abnormally bulging, protruding, or swollen gums are a possible sign of disease.

Abscesses. Deepening periodontal pockets between the gums and bone can become blocked by tartar or food particles. Infection-fighting white blood cells become trapped and die. Pus forms, and an abscess develops. Abscesses can destroy both gum and tooth tissue, cause nearby teeth to become loose and painful, and may cause fever and swollen lymph nodes.

Pain is usually not a symptom, which partly explains why the disease may become advanced before treatment is sought and why some patients avoid treatment even after periodontitis is diagnosed.

Causes

Periodontal disease is marked by bacterial overgrowth. However, a persistent immune response to chronic infections in the mouth is believed to play a major role in gum destruction.

In the healthy mouth, more than 350 species of microorganisms have been found. Periodontal infections are linked to fewer than 5% of these species. Healthy and disease-causing bacteria can generally be grouped into two categories:

The harmless or helpful bacteria are usually known as gram positive aerobic bacteria.
In periodontal disease, the bacterial balance shifts over to gram negative anaerobic bacteria. Inflammatory disease and injury cannot develop without these bacteria.

Following are some of the bacteria most implicated in periodontal disease and bone loss:

Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis. These two bacteria appear to be particularly likely to cause aggressive periodontal disease. Both P. gingivalis and A. actinomycetemcomitans, along with multiple deep pockets in the gum, are associated with resistance to standard treatments for gum disease. P. gingivalis may double the risk for serious gum disease. P. gingivalis produces enzymes, such as one called arginine-specific cysteine proteinase, which may be the specific destructive factors that disrupt the immune system and lead to subsequent periodontal connective tissue destruction.
Bacteroides forsythus is also strongly linked to periodontal disease.
Other bacteria associated with periodontal disease are Treponema denticola, T. socranskii, and P. intermedia. These bacteria, together with P. gingivalis, are frequently present at the same sites, and are associated with deep periodontal pockets.

Some bacteria are related to gingivitis, but not plaque development. They include various streptococcal species.

Evidence now suggests that periodontal disease is an autoimmune disorder, in which immune factors in the body attack the person's own cells and tissue -- in this case, those in the gum. It appears to work as follows:

The bacteria that form plaque and tartar release toxins that stimulate the immune system to overproduce powerful infection-fighting factors called cytokines.
Ordinarily, cytokines are important for healing. In excess, however, they can cause inflammation and severe damage. Cytokines of particular importance in periodontal disease are known as tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta, which are very active in the mouth, and are important in causing destructive inflammation.
In addition, white blood cells produced by the immune response to bacteria also release a family of enzymes called matrix metalloproteinases (MMPs), which break down connective tissue.

Studies suggest that this inflammatory response may have damaging effects not only in the gums but also in organs throughout the body, including the heart.

Certain herpes viruses (herpes simplex and varicella-zoster virus, the cause of chickenpox and shingles) are known causes of gingivitis. Other herpes viruses (cytomegalovirus and Epstein-Barr) may also play a role in the onset or progression of some types of periodontal disease, including aggressive and severe chronic periodontal disease. All herpes viruses go through an active phase followed by a latent phase and possibly reactivation.

Some experts theorize that these viruses may cause periodontal disease in different ways, including release of tissue-destructive cytokines, overgrowth of periodontal bacteria, suppressing immune factors, and initiation of other disease processes that lead to cell death.

Risk Factors

More than 75% of American adults have some form of gum disease, but according to a major survey, only 60% have any significant knowledge about the problem. Gum inflammation and ulcers are common, and not all people with these problems develop periodontal disease. Still, about 30% of people are genetically susceptible to periodontal disease. Other factors also put individuals at higher risk.

Lack of Oral Hygiene. Lack of oral hygiene encourages bacterial buildup and plaque formation.

Sugar and Acid. The bacteria that cause periodontal disease thrive in acidic environments. Therefore, eating sugars and other foods that increase the acidity in the mouth increase bacterial counts.

Poorly Contoured Restorations. Poorly contoured restorations (fillings or crowns) that provide traps for debris and plaque can also contribute to its formation.

Anatomical Tooth Abnormalities. Abnormal tooth structure can increase the risk.

Wisdom Teeth. Wisdom teeth, also called third molars, can be a major breeding ground for the bacteria that cause periodontal disease. In fact, for patients in their 20s, periodontal disease is most likely to occur around the wisdom teeth. Research suggests that periodontitis can occur in wisdom teeth that have broken through the gum as well as teeth that are impacted (buried). Periodontal disease can also be present even in patients with wisdom teeth who do not have any symptoms. Experts recommend that adolescents and young adults with wisdom teeth should have a dentist check for signs of periodontal disease

Children and Adolescents. Gingivitis, in varying degrees, is nearly a universal finding in children and adolescents. In rare genetic cases, children and adolescents are subject to destructive forms of the disease. Researchers have also observed some of the organisms seen in periodontal disease in young children without signs of gum problems. Healthy children, however, do not generally harbor two primary periodontal bacteria, P. gingivalis and T. denticola. The disease is also uncommon in teenagers.

Adults. One survey reported that 3.6% of adults between the ages of 18 - 34 had periodontal disease. As people age, the risk for periodontal disease increases. Over half of American adults have gingivitis surrounding 3 - 4 teeth, and 30% have significant periodontal disease surrounding 3 - 4 teeth. In a study of people over 70 years old, 86% had at least moderate periodontitis and over a quarter of them had lost their teeth.

About three-quarters of periodontal office visits are made by women, even though women tend to take better care of their teeth than men. Female hormones affect the gums, and women are particularly susceptible to periodontal problems. Hormone-influenced gingivitis appears in some adolescents, in some pregnant women, and is occasionally a side effect of birth control medication.

Before Menstruation. Gingivitis may flare up in some women a few days before they menstruate, when progesterone levels are high. Gum inflammation may also occur during ovulation. Progesterone dilates blood vessels causing inflammation, and blocks the repair of collagen, the structural protein that supports the gums.

Pregnancy. Hormonal changes during pregnancy can aggravate existing gingivitis, which typically worsens around the second month and reaches a peak in the eighth month. Pregnancy does not cause gum disease, and simple preventive oral hygiene can help maintain healthy gums. Any pregnancy-related gingivitis usually resolves within a few months of delivery. Because periodontal disease can increase the risk for low-weight infants and cause other complications, it is important for pregnant women to see a dentist.

Oral Contraceptives. Some studies report that oral contraceptives containing the synthetic progesterone desogestrel (but not dienogest, another common progesterone) increase the risk for periodontal disease.

Menopause. Estrogen deficiency after menopause reduces bone mineral density, which can lead to bone loss. Bone loss is associated with both periodontal disease and osteoporosis. Bone loss in the alveolar bone (which holds the tooth in place) may be a major predictor of tooth loss in postmenopausal women. Periodontal disease is the main cause of alveolar bone loss. During menopause, some women may also develop a rare condition called menopausal gingivostomatitis, in which the gums are dry, shiny, and bleed easily. Women may also experience abnormal tastes and sensations (such as salty, spicy, acidic, burning) in the mouth.

Periodontal disease often occurs in members of the same family. Genetics, intimacy, hygiene, or a mixture of factors may be responsible. Studies have found that children of parents with periodontitis are 12 times more likely to have the bacteria thought to be responsible for causing plaque and, eventually, periodontal disease.

Genetic Factors. Genetic factors may play the critical role in half the cases of periodontal disease. Up to 30% of the population may have some genetic susceptibility to periodontal disease. For example, some people with severe periodontal disease have genetic factors that affect the immune factor interleukin-1 (IL-1), a cytokine involved in the inflammatory response. Such individuals are up to 20 times more likely to develop advanced periodontitis than those without these genetic factors. Early onset and rapidly progressive periodontal disease also have strong genetic components.

Intimacy. Intimate partners and spouses of people with periodontal disease may also be at risk. Researchers have found that the bacteria P. gingivalis may be contagious after exposure to an infected person over a long period of time. There is no risk from short exposure such as after a fast kiss or when sharing an eating utensil.

Smoking is the single major preventable risk factor for periodontal disease. The habit can cause bone loss and gum recession even in the absence of periodontal disease. A number of studies indicate that smoking and nicotine increase inflammation by reducing oxygen in gum tissue and triggering an over-production of immune factors called cytokines (specifically ones called interleukins). In excess, cytokines are harmful to cells and tissue.

Furthermore, when nicotine combines with oral bacteria, such as P. gingivalis, the effect produces even greater levels of cytokines and eventually leads to periodontal connective tissue breakdown. Studies suggest that smokers are 11 times more likely than nonsmokers to harbor the bacteria that cause periodontal disease and four times more likely to have advanced periodontal disease. In one study more than 40% of smokers lost their teeth by the end of their lives.

The risk of periodontal disease increases with the number of cigarettes smoked per day. Smoking cigars and pipes carries the same risks as smoking cigarettes. Exposure to secondhand smoke is also associated with a 50 - 60% increased risk for developing periodontal disease, according to one study. Fortunately, when smokers quit, their periodontal health gradually recovers to a state comparable to that of nonsmokers.

Diabetes. Much evidence exists on the link between type 1 and 2 diabetes and periodontal disease. Diabetes causes changes in blood vessels, and high levels of specific inflammatory chemicals such as interleukins, that significantly increase the chances of periodontal disease. High levels of triglycerides (which are common in type 2 diabetes) also appear to impair periodontal health. Obesity, common in people with type 2 diabetes, may also predispose a person to gum disease. Controlling both type 1 and 2 diabetes may help reduce periodontal problems. For children with diabetes, good oral hygiene should begin at a young age. A 2006 study suggested that gum problems can start as early as 6 years of age in children with diabetes.

Osteoporosis and Osteonecrosis. Osteoporosis (loss of bone density) has been associated with periodontal disease in postmenopausal women. There have also been a few reports of osteonecrosis (bone decay) of the jaw in patients who take oral bisphosphonate drugs such as alendronate (Fosamax). Symptoms of osteonecrosis of the jaw include loose teeth, exposed jawbone, pain or swelling in the jaw, gum infections, and poor healing of the gums. As a precaution, the American Dental Association (ADA) recommends that patients who are prescribed bisphosphonate drugs get a thorough dental exam before beginning drug therapy, or as soon as possible after beginning therapy. The ADA also recommends that patients who take oral bisphosphonate drugs should discuss with their dentists any potential risks from dental procedures (such as extractions and implants) that involve the jawbone. In any case, be sure to inform your dentist if you are taking a bisphosphonate drug.

Osteoporosis is a condition marked by progressive loss of bone density, thinning of bone tissue, and increased risk of fractures. Osteoporosis may result from disease, dietary or hormonal deficiency, or advanced age. Regular exercise and vitamin and mineral supplements can reduce and may even reverse loss of bone density.

Giving intravenous bisphosphonates to patients being treated for bone cancer, or other cancers that have spread to the bone, increases their risk for developing osteonecrosis by 1 - 10%. Patients who take oral bisphosphonate drugs also have a slight risk, but 94% of osteonecrosis of the jaw cases involve patients who received bisphosphonates intravenously. If possible, see a dentist for a complete oral exam before beginning bisphosphonate therapy. In any case, be sure to inform your dentist if you are receiving intravenous bisphosphonates. Your dentist or oral surgeon may need to take special precautions when performing dental surgery

Herpes-Related Gingivitis. Herpes virus is a common cause of gingivitis in children and has become increasingly common in adults. It typically starts out with a purplish color and "boggy" sensation in the gums. Multiple blisters may form across the mucus membranes in the mouth and gums, followed by ulcers. They usually resolve in 7 - 14 days.

HIV-Associated Gingivitis. HIV-associated gingivitis has been reported in 15 - 50% of patients with HIV or AIDS. HIV-positive individuals harbor larger numbers of periodontal bacteria (candida albicans, P. gingivalis, black-pigmented anaerobic rods, and A. actinomycetemcomitans) than people without HIV. Severe pain is characteristic, along with odor, spontaneous bleeding, ulcers, and swollen, bright red gums. The inflammation never recedes, but halitosis and acute episodes can be managed by conventional cleaning treatments. Its severest form, known as necrotizing stomatitis, can be diagnostic for AIDS. In addition to bleeding, the gums in the front of the mouth are a yellowish-gray color, and bone thrusts out.

Autoimmune Diseases. Autoimmune conditions (Crohn's disease, multiple sclerosis, rheumatoid arthritis, lupus erythematosus, CREST syndrome) have been associated with a higher incidence of periodontal disease. Some research suggests that periodontal disease may even play some causal role. For example, one study suggested that P. gingivalis, one of the major bacteria in periodontal disease, was associated with destructive processes in the brain leading to multiple sclerosis. Still, more research is needed to determine a definitive association between these diseases.

Other Diseases. People with tuberculosis, syphilis, Wegener's granulomatosis, amyloidosis, and many genetic disorders are also at higher risk for periodontitis.

Vitamin C helps the body repair and maintain connective tissue, and its antioxidant effects are important in the presence of tissue-destroying oxidants in periodontal disease. Research indicates that vitamin C deficiency contributes to periodontal disease. A study of more than 12,000 adults found that people who consumed less than the recommended daily allowance of vitamin C, 60 mg (about one orange) were 1.5 times more likely to develop severe gingivitis than those who consumed more than 180 mg each day. Vitamin C levels are especially depleted in smokers. Eating citrus fruits high in vitamin C (such as grapefruit) may be helpful for patients with periodontitis.

Dental disease is most likely to affect the poor. Children and the elderly suffer the worst oral care, and ethnic minorities follow. In the United States, the lack of access to dental insurance is a contributing factor. In a survey of residents of five states (Arizona, California, Hawaii, Oregon, and Wisconsin), the rate of total tooth loss was less than 20%. In three states (Kentucky, Louisiana, and West Virginia) it was greater than 40%.

Gingival overgrowth can be a side effect of nearly 20 different drugs, most commonly phenytoin (Dilantin), cyclosporine (Sandimmune), and a short-acting form of the calcium channel blocker nifedipine (Procardia).

Several other conditions can also cause gum inflammation, and some have been associated with periodontal disease. They include:

Mouth breathing
Psychologic stress. Stress can affect the immune system. Some studies suggest that stress can influence the development of chronic inflammatory diseases, like periodontitis.
Alcohol abuse. One study reported a higher incidence of periodontal disease, tooth decay, and possibly precancerous areas in patients who abuse alcohol.
Canker sores (aphthous ulcers)

Self-injury in psychologically disturbed patients
Hereditary gingival fibromatosis. A rare genetic disease associated with both gum overgrowth and hairiness. It is often associated with gingivitis and periodontal disease.
Desquamative gingivitis. With this condition the outer layer of the gum tissue desquamates (peels away), exposing an acutely red surface. It usually occurs as a result of an allergic reaction or of skin diseases such as lichen planus, benign mucous membrane pemphigoid, bullous pemphigoid, and pemphigus vulgaris. (Bacteria may also play a role in this gum disease.) This condition generally resolves when the underlying problem is treated. It is fairly common in middle-aged women.

Complications

The ultimate outcome of uncontrolled periodontal disease is tooth loss. As the destructive factors cause the breakdown of bone and connective tissue, teeth lose their anchor.

A much less severe but nevertheless distressing problem caused by periodontal disease is bad breath, although coatings on the tongue may contribute more to bad breath than periodontal disease.

Studies have reported that people who have heart disease have a 1.5 - 4 times increased risk for periodontal disease. (The risk is highest for patients with extensive gum disease, bleeding from every tooth.) Acute coronary syndrome, high blood pressure (hypertension), and high cholesterol have also been associated with periodontal disease.

Periodontal disease has also been linked to stroke and coronary artery disease (CAD). The more severe the periodontitis, the greater the risk for heart problems. Many experts, however, are still not sure whether periodontal disease is a risk factor for stroke or a marker that reflects various risk factors common to both conditions.

A stroke is caused by a loss of blood circulation to areas of the brain. The blockage usually occurs when a clot or piece of atherosclerotic plaque breaks away from another area of the body and lodges within the blood vessels of the brain.

Recent evidence suggests that the inflammatory response may be the common element. This is an over-reaction of the immune system that causes injury to tissues in the body. A common link between patients with heart conditions and periodontal disease may be elevated levels of C-reactive protein (CRP), a marker for the inflammatory response. Some experts believe that immune factors causing this response are released into the bloodstream during periodontal disease and cause injury in the arteries supplying blood to the heart.

Other evidence suggests that the periodontal disease bacteria themselves -- particularly P. gingivalis, T. denticola, T. forsythia, and streptococci species -- may be the main culprit. In 2005, results from the NIH-sponsored Oral Infections and Vascular Disease Epidemiology Study (INVEST) determined an association between cardiovascular disease and the bacteria that cause periodontal disease. In this study, higher levels of periodontal bacteria were associated with thicker carotid arteries (a predictor of heart attack and stroke), regardless of C-reactive protein levels. While this study's findings are an important advance in understanding the relationship between periodontal and heart disease, it is still not clear if periodontal disease actually causes heart disease. Researchers hope that future results from INVEST will clarify this issue.

Experts are still not sure if treating gum disease can reduce the risks of heart disease and improve health outcomes for patients with periodontal disease and vascular heart problems. Studies have been mixed, but research is ongoing.

Diabetes is not only a risk factor for periodontal disease -- periodontal disease itself can worsen diabetes. Some evidence suggests that the bacteria that causes periodontal disease may enter the bloodstream and activate cytokines (damaging immune system factors), which then destroy cells in the pancreas where insulin is produced. Some studies indicate that treating periodontal disease can reduce the need for insulin and improve blood sugar control in some people with diabetes.

Bacteria that reproduce in the mouth can also be carried into the airways in the throat and lungs, increasing the risks for respiratory diseases and worsening chronic lung conditions, such as emphysema.

Many studies strongly indicate that bacterial infections that cause moderate-to-severe periodontal disease in pregnant women can increase the risk for premature delivery and low birth weight infants. The more severe the infection, the greater the risk to the baby. Research indicates that bacteria from gum disease and tooth decay may trigger the same factors in the immune system as genital and urinary tract infections. These biologic substances, called prostaglandins and tumor necrosis factor, produce inflammation in the cervix and uterus that can cause premature dilation and contractions. Research also suggests that periodontal disease increases the risk for preeclampsia, a life-threatening disorder that occurs in mid- to late pregnancy and is characterized by high blood pressure.

Experts recommend that women have a periodontal examination before becoming pregnant or as soon as possible thereafter. Because women with diabetes are at higher risk for periodontal disease, it is especially important that they see a dentist early in pregnancy. Experts are still not sure if treating periodontal disease can improve birth outcomes. A 2006 study in the New England Journal of Medicine indicated that the treatment does not affect pre-term birth or birth weight. However, the researchers reported that periodontal treatment is definitely safe for pregnant women.

Prevention

Healthy habits and good oral hygiene are critical in preventing gum disease. Regular and effective tooth brushing and mouth washing, however, are effective only above and slightly below the gum line. Once periodontal disease develops, more intensive treatments are needed.

It is important to reduce both the quantity and, in particular, the frequency of sugar intake. Avoid snacks and drinks with sugar (other than natural sugars found in fruits and vegetables). Eat sugar-containing foods with meals, ideally followed by brushing. Since fruit juices can also cause tooth erosion in children, parents should emphasize milk and water.

Smoking may play a significant role in over half the cases of chronic periodontal disease, according to research published in 2000. For smokers, quitting is one of the most important steps toward regaining periodontal health.

Fluoride treatment in children has helped to account for the decline in periodontal disease in adults. Because fluoride prevents decay, back molars, which keep the teeth in place, are spared, and are thus less vulnerable to bacteria. Even before teeth first erupt, babies' gums should be wiped clean with a bit of gauze bearing a dab of fluoride toothpaste. Supplementation with fluoride tablets or drops may be recommended for children 6 months or older who drink unfluoridated water or who are at risk for dental problems. A prescription from the child's pediatrician or dentist is required.

Some dentists recommend a fluoride gel for adult patients who are still at risk for tooth decay or sensitivity, but extra fluoride is generally not necessary for adults who use fluoride toothpaste.

Periodontitis is a silent disease. People with the disease rarely experience pain and may not be aware of the problem. A periodontal examination by a general dentist once or twice a year should reveal any incipient or progressive problems. A full mouth series of x-rays is advised every 2 - 3 years. This will alert the dentist to early bone loss and other disorders of the oral cavity.

Dentists now often perform Periodontal Screening and Recording (PSR) using a probe to measure gum pockets. Previously performed only by periodontists, this procedure is now encouraged as part of a regular dental examination. The dentist will identify any areas where deep pocketing has occurred, where the health of the gingiva appears compromised, and where there is undue mobility of teeth. It is the general dentist's responsibility to identify periodontal disease and inform the patient. If the condition is severe, the dentist may want to refer the patient to a periodontist.

Correct tooth brushing, mouth cleansing, and flossing should be everyone's defense against periodontal disease. (However, good hygiene is probably not sufficient to prevent periodontal disease in many people. Regular visits to a dentist are extremely important, especially for high-risk individuals.)

Brushing Guidelines. The following are some recommendations for brushing:

Use a dry brush. One study reported that when people brushed their teeth without toothpaste first, using a soft dry brush, their plaque deposits were reduced by 67%, and gum bleeding dropped by 50%.
No brush of any size, shape, or gimmick is effective if it is incorrectly positioned in the mouth. Place the brush where the gum meets the tooth, with bristles resting along each tooth at a 45-degree angle.
Begin by dry brushing the inside the bottom row of teeth, then the inner top teeth, and last the outer surfaces.
Wiggle the brush back and forth so the bristles extend under the gum line.
Scrub the broad, biting surfaces of the back teeth.
Dry brushing should take about a minute and a half.
A paste is then applied, and the teeth should again be brushed in the same way.
The tongue should be scrubbed for a total of about 30 seconds. A tongue scraper used with an anti-bacterial mouthwash (such as Listerine) is more effective than a toothbrush in removing bacteria.
Rinse the toothbrush thoroughly and then tap it on the edge of the sink at least five times to get rid of debris.
Flossing should finish the process. A mouthwash may also be used.

If brushing after each meal is not possible, rinsing the mouth with water after eating can reduce bacteria by 30%.

Toothbrushes. A vast assortment of brushes of varying sizes and shapes are available, and each manufacturer makes its claim for the benefits of a particular brush. Look for the American Dental Association (ADA) seal on both electric and regular brushes.

In spite of the wide variety of nonelectric toothbrushes, both in shape and bristle design, a study of eight brands found no significant differences in effectiveness among them.

Electric toothbrushes, particularly those with a stationary grip and revolving tufts of bristles, can be advantageous for some people with physical disabilities. Electric toothbrushes with heads that move back and forth up to 4,200 times a minute remove significantly more plaque than ordinary brushes. Even more high-tech brushes are now available that use sound waves to remove plaque.

In general, studies have reported no differences between electric and manual toothbrushes in their ability to remove plaque. (One study showed considerable improvement in groups using sonic toothbrushes, particularly in those with moderate periodontal disease.) Experts recommend, however, that if a regular toothbrush works, it isn't necessary to buy an expensive electric one.

For individuals with average dexterity, a four- or five-rowed, soft, nylon-bristled toothbrush is sufficient. The most important factor in buying any toothbrush, electric or manual, is to choose one with a soft head. Soft bristles get into crevices easier and do not irritate the gums, thereby reducing the risk of exposing teeth below the gum line compared to hard brushes.

Experts generally recommend replacing toothbrushes every 1 - 3 months. Not only do they become breeding grounds for bacteria, but the worn bristles are less effective at removing plaque.

Toothpaste. The object of a good toothpaste is to reduce the development of plaque and eliminate periodontal-causing microorganisms without destroying the organisms that are important for a healthy mouth. All brands should show ADA approval. Even a good toothpaste, however, cannot be delivered past 3 mm below the gum line, where periodontitis develops.

Toothpastes are a combination of abrasives, binders, colors, detergents, flavors, fluoride, humectants, preservatives, and artificial sweeteners. Avoid highly abrasive toothpastes, especially for individuals whose gums have receded.

Ingredients contained in toothpastes may include:

Fluoride. Most commercial toothpastes contain fluoride, which both strengthens tooth enamel against decay and enhances remineralization of the enamel. Fluoride also inhibits acid-loving bacteria, especially after eating, when the mouth is more acidic. This antibacterial activity may help control plaque.
Triclosan. Triclosan is an anti-bacterial substance that may help reduce mild gingivitis.
Metal salts. Metal salts, such as stannous and zinc, serve mostly as anti-bacterial substances in toothpastes. Stannous fluoride gel toothpastes do not reduce plaque, however, even though they have some effect against the bacteria that cause it, but slightly reduce gingivitis.
Peroxide and baking soda. Toothpastes with these ingredients claim to have a whitening action, but while they may help remove stains there is little evidence they whiten the actual color of the teeth. In addition, these substances appear to offer no benefits against gum disease.
Antibacterial sugar substitutes (xylitol), and detergents (delmopinol)

Mouthwashes. The American Dental Association recommends (in addition to daily brushing and flossing) antimicrobial mouthwash to help prevent and reduce plaque and gingivitis, and fluoride mouthwashes to help provide additional protection against tooth decay.

Chlorhexidine (Peridex or PerioGard) is an antimicrobial mouthwash available by prescription only. It reduces plaque by 55% and gingivitis by 30 - 45%. Patients should rinse for 1 minute twice daily. They should wait at least 30 minutes (and preferably 2 hours) between brushing and rinsing since chlorhexidine can be inactivated by certain compounds in toothpastes. It has a bitter taste. It also binds to tannins, which are in tea, coffee, and red wine, so it has tendency to stain teeth in people who drink these beverages. Studies are mixed as to its effectiveness for preventing or reducing periodontal disease.
Listerine is another antimicrobial mouthwash. It is composed of essential oils and is available over the counter. It reduces plaque and gingivitis, when used for 30 seconds twice a day. It leaves a burning sensation in the mouth that most people better tolerate after a few days of use. The usual regimen is to rinse twice a day. (Listerine PocketPaks, which are strips that dissolve on the tongue, have no proven effects on plague and gingivitis.)
Mouthwashes containing cetylpyridinium (Scope, Cepacol) have moderate antimicrobial effect on plaque, but only if they are used an hour after brushing. None are as effective as Listerine or chlorhexidine, but they may still have some value for people who cannot tolerate the other mouthwashes.
Mouthwashes containing stannous fluoride and amine fluoride (Meridol) are moderately effective, but are also not as effective as effective as Listerine or chlorhexidine.
Fluoride mouthwashes (Act) are helpful in preventing cavities.
Mouthwashes that contain alcohol are dangerous for children and should be kept away from them.

Flossing. The use of dental floss, either waxed or unwaxed, is critical in cleaning between the teeth where the toothbrush bristles cannot reach. In spite of this, nearly two-thirds of people do not floss.

To floss correctly, the following steps may be helpful:

Break off about 18 inches of floss and wind most of it around the middle finger of one hand and the rest around the other middle finger.
Hold the floss between the thumbs and forefingers and gently guide and rub it back and forth between the teeth.
When it reaches the gum line, the floss should be curved around each tooth and slid gently back and forth against the gum.
Finally, rub gently up and down against the tooth. Repeat with each tooth, including the outside of the back teeth.
If, on repeated flossing attempts, the floss becomes shredded or cannot be removed easily from between the teeth, a rough crown or overhanging filling may be the cause. In such cases, the restoration should be redone. Such areas create spaces for the collection of food debris, plaque, and calculus.

Here are some tips in choosing the right floss or flossing device:

Use a floss that does not shred or break.
Avoid a very thin floss, which can cut the gum if brought down with too much force or not guided along the side of the tooth.
A floss threader is an invaluable aid for the person who has bridgework. Made of plastic, it looks like a needle with a huge eye, or loop. A piece of floss is threaded into the loop, which can then be inserted between the bridge and the gum. The floss that is carried through with it can then be used to clean underneath the false tooth or teeth and along the sides of the abutting teeth.
Another handy device for cleaning under bridges is a Proxabrush, which is an interdental cleaner. This is a tiny narrow brush that can be worked in between the natural teeth and around the attached false tooth or teeth.
Special toothpicks such as Stim-U-Dent may be effective for wide spaces between teeth but should never replace flossing. Standard toothpicks should never be used for regular hygiene.
Electronic products, such as water piks, are also helpful. These devices are expensive but may improve flossing compliance.

Producing Saliva and Drinking Water. Saliva is important for diluting the toxins created by plaque. Drinking at least 7 glasses of water a day helps reduce inflammation in the mouth by producing more saliva. Increasing water intake is particularly important as one ages, when less saliva is produced.

Diagnosis

The dental practitioner typically performs a number of procedures to determine a diagnosis of periodontal disease.

The dentist will first take a medical history to reveal any past or present periodontal problems, any underlying diseases that might be contributing to the problem, and any medications the patient is taking. After noting the general state of oral hygiene, the dentist may ask about the quality of home dental care.

Inspection of the Gum Area. The dentist inspects the color and shape of gingival tissue on the cheek (buccal) side and the tongue (lingual) side of every tooth and compares these qualities to the healthy ideal. Redness, puffiness, and bleeding upon probing indicate inflammation. If the gum formation between teeth is blunt and not pointed, acute necrotizing periodontal disease may be indicated.

Periodontal Screening and Recording (PSR). PSR is a painless procedure used to measure and determine the severity of periodontal disease:

The dentist uses a mirror and a periodontal probe, a fine instrument calibrated in millimeters (mm), which is used to measure pocket depth. (A new automatic probing device may prove to be even more sensitive and accurate than the standard manual probe that most dentists use.)
The probe is held along the length of the tooth with the tip placed in the pocket. The tip of the probe will then touch the point where the connective tissue attaches to the tooth.
The dentist will "walk" the probe to six specified points on each tooth, three on the buccal (cheek) and three on the lingual (tongue) sides. The dentist measures the depth of the probe at each point.
Pocket depths greater than 3 mm indicate disease.

These measurements help determine the condition of the connective tissue and amount of gingival overgrowth or recession. PSR appears to be even more reliable than x-rays in diagnosing gum disease.

Testing Tooth Movement. Tooth mobility is determined by pushing each tooth between two instrument handles and observing any movement. Mobility is a strong indicator of bone support loss.

X-rays. X-rays are taken to show any loss of bone structure supporting the teeth. Eighteen x-rays make up the full mouth series necessary for diagnosis.

Treatment

Studies support the effectiveness of active treatment combined with a strict maintenance program for patients with periodontal disease. In one study, for example, people with periodontal disease who were inconsistent in caring for their gums after treatment had 5.6 times the risk for tooth loss as those who were very vigilant.

Some dentists have reported a success rate of 85% when professional treatment and good home maintenance are combined. Treatment helps nonsmokers more than smokers, particularly when pockets are deep and persistent. Some studies suggest that periodontal treatment in people with type 2 diabetes helps improve blood sugar levels. Whether treatment will help reduce other health risks, including heart attack and stroke, is unknown.

Treatment Goals. Once periodontal disease has been identified, the goals of treatment are:

To arrest and control the progress of the disease
To leave the periodontal tissues in an easily maintainable state
If possible, to restore the supporting structures, which include bone, gum tissue, and ligaments

Treatment Phases. To achieve these goals, there are various approaches:

Initial cleaning, scaling, and curettage
Surgery -- if needed for reducing deep pockets that remain underneath the gum after extensive cleaning sessions
Low-dose oral or topical antibiotics
Maintenance

After the active treatment is completed and the mouth is in a relative state of health, the patient should have regular cleanings lasting 45 minutes to 1 hour, approximately every 3 months. These may be done by the dental hygienist, the periodontist, or the general dentist. The patient may alternate between them. Home care, of course, must be continued.

Antibiotics Before Treatment. In cases where the individual has a mitral valve prolapse or history of rheumatic heart disease, pretreatment with an appropriate antibiotic is required before any dental work, including cleaning. This is necessary to prevent the possibility of bacterial endocarditis, which can be life threatening.

Scaling, polishing, and sometimes curettage are used to manage periodontal disease. They are usually accomplished in a series of three to four visits spaced about a week apart. (Patients might ask their dentist about the gas nitrous oxide, which is helpful for many patients and may reduce the visits to a single one.) The dental hygienist or practitioner generally uses both ultrasonic and manual instruments to remove calculus.

Calculus above the gum is easily seen. The dental professional usually detects calculus below the gum by careful probing with an instrument.
The hygienist or dentist may use an ultrasonic instrument for removal of the more accessible calculus. This probe-like device vibrates at a frequency range higher than is audible to the human ear. Some people with low tolerance for the ultrasonic probe may wish to request nitrous oxide.
A spray of water is used with ultrasound to prevent overheating and to flush out the debris that is dislodged.
The dental professional will scrape the plaque from above and below the gum line (called scaling). When the probe contacts the rock-like calculus, deposits fracture off the tooth fairly efficiently.
The hygienist or dentist will then smooth the rough spots on the tooth. Smoothing the surface helps remove bacteria that collect there (root planing) and also helps the gums reattach.
Polishing is the finishing procedure. It uses a rubber cup with an abrasive paste to remove plaque and stains on the crown portion of the tooth. It produces a smooth surface, making it temporarily harder for plaque to adhere.

After the cleaning procedure, the dentist will check the pocket depths around the teeth after the cleaning process has been completed. Further treatment needs are determined by the results of these initial sessions:

If the cleaning processes have reduced inflammation, observation only is needed.
If an abscess is present, surgery may be required.

Finally, the dental hygienist or practitioner should offer thorough instructions on home care to insure the removal of bacteria on a daily basis. This includes proper use of the toothbrush, paste, mouth rinses, floss, floss threaders, and proxabrushes. Home care can effectively eliminate the plaque above the gums and down to 2 mm below the gums.

Gingival curettage removes the soft tissue lining of the periodontal pockets in order to completely eliminate bacteria and diseased tissue. It may be used along with scaling and root planing, but achieves a deeper and more complete cleaning. Evidence indicates, however, that it does not contribute any additional benefits beyond simple scaling and planing.

Surgery allows access for deep cleaning of the root surface, removal of diseased tissue, and repositioning and shaping of the bones, gum, and tissues supporting the teeth. Surgical procedures vary depending on the individual diagnosis and needs of the patient. The basic procedure is known as open flap curettage. It involves:

The periodontal surgeon lifts, or flaps, the gums away from the tooth and surrounding bone.
The diseased root surfaces are cleaned and curetted (scraped) to remove deposits.
Gum tissue is replaced into positions to minimize pocket depth.
The periodontist may also contour the remaining bone and attempt to regenerate lost bone and gingival attachment through bone grafts and guided tissue regeneration or the use of enamel matrix protein derivatives.

There is some debate about whether this procedure is any more effective in preventing disease progression than non-surgical therapies, such as low-dose doxycycline, short-term antibiotics, or antibiotic gels. Some studies have reported that although surgical treatment reduced pocket depth more than non-surgical therapies for at least a year after the procedure, benefits from surgery do not persist beyond 5 years, except in very deep pockets.

Postsurgery Pain and Discomfort. Post-surgery discomfort is usually managed easily with over-the-counter medications such as ibuprofen. If discomfort is severe, stronger analgesics may be prescribed. Some patients experience sensitivity to hot or cold temperatures from exposed roots. These problems can be managed with topical fluoride treatments or, in severe cases, with dental restoration.

Guided Tissue Regeneration. A more advanced technique, called guided tissue regeneration, is used to stimulate bone and gum tissue growth:

First, the root surfaces and diseased bone are meticulously cleaned out. Preventing bacterial contamination is very important. The more residual bacteria, the greater the chance that the treatment will fail.
A specialized piece of fabric is sewn around the tooth to cover the crater in the bone left after the cleaning. It is either absorbable or nonabsorbable. (Some studies report highly beneficial results with new absorbable materials, including those coated with the antibiotic doxycycline.)
The gum is then sewn over the fabric. The fabric prevents the gum tissue from growing down into the bone defect and allows the bone and the attachment to the root to regenerate.
After 4 - 6 weeks, the nonabsorbable fabric must be removed using a minor surgical procedure. The absorbable membrane may be left in. In general, there is little difference in outcome between absorbable and nonabsorbable procedures. The absorbable fabric may not be as effective as standard grafts if gum tissue is thin, although newer materials may prove to produce better results.

Bone Grafting. In some cases of severe bone loss, the surgeon may attempt to encourage regrowth and restoration of bone tissue that has been lost through the disease process. This involves bone grafting:

The surgeon places bone graft material into the defect.
The material may be either bone from the same patient or a substance called decalcified freeze-dried bone allografts (DFDBA) which is obtained from a donor.
This material then stimulates new bone growth in the area.

Enamel Matrix Protein Derivative. Amelogenin is a derivative of a major protein in the structure (the matrix) of enamel that helps stimulate gum tissue growth. A gel containing amelogenin (Emdogain) is applied during surgery and forms a coat over the roots of the teeth. The gel itself dissolves after 2 days, leaving the active substance behind. Studies report that it is safe and may significantly reduce the effects of periodontal disease. One study suggested that the benefits, as indicated by bone attachment, can persist for at least 4 years. (Results were similar to guided tissue regeneration.)

Gum grafting techniques can also be very useful for improving the looks of the gum as well as adding support to the teeth. During this procedure, the periodontist takes gum tissue from the palate or another donor source to cover the exposed root in order to even the gum line and reduce sensitivity. Other procedures are available to improve the look of the gums and teeth. The gum line can be sculpted to improve uneven or excess gums and to cover exposed roots as gums recede.

Periodontists report that they are achieving great success with tooth implants in patients who have lost teeth due to periodontal disease. The average cost for a single implant is high, however, and one implant requires 5 - 7 months for completion.

Medications

Antibiotics are often used in combination with surgery, curettage, or alone to eliminate or prevent disease-causing bacteria after periodontal procedures. They are being investigated in oral forms as well as in topical forms that are applied directly to the gum. Increasingly, dental professionals are finding that local application of antibiotics is more effective than periodontal surgery alone. They may even prove to be an alternative to surgery.

Some experts are concerned, however, that long-term use of antibiotics increases the risk of bacterial resistance to these drugs, which is a growing health problem in general. Of some encouragement was a 2000 review, which indicated that low-dose antibiotics do not increase the risk of bacterial resistance. However, long-term studies are still needed

Antibiotics given orally and at standard doses have some limited applications for periodontal disease. They are typically given for an acute infection. Long-term use of antibiotics is advised for the control of juvenile periodontitis, refractory periodontitis, rapidly progressing periodontitis, and prepubertal periodontitis. Specific antibiotics used in periodontal disease include:

Tetracycline antibiotics -- which include tetracycline hydrochloride, doxycycline, and minocycline -- are the primary drugs used. They not only have anti-bacterial actions but also reduce inflammation and help block collagenase, the protein that destroys connective tissue and bone, even in low doses. In fact, these two actions seem to contribute most to periodontal protection, rather than their antibacterial properties. Short-term use of standard-dose doxycycline (a 10-day treatment) is used for treating acute periodontal infections and for eliminating inflammation. Topical application and long-term use of these antibiotics are showing particular promise.
Some macrolide antibiotics (roxithromycin) may have actions against inflammation and growth involved in periodontal disease.
Some quinolone antibiotics (moxifloxacin, ciprofloxacin) may specifically target A. actinomycetemcomitans, an important bacteria in periodontal disease.
Metronidazole (Flagyl) in combination with tetracycline or amoxicillin (a penicillin) may be used for severe and chronic periodontal disease.

There is growing bacterial resistance to many of these antibiotics, such as roxithromycin and metronidazole, therefore limiting their use in periodontal disease. One study indicated, however, that 3 months after antibiotic administration, the percentage of bacteria that could be eliminated with standard antibiotics returned to normal.

Topical application of antibiotics to the gum surface does not affect the entire body like oral antibiotics do, and they are preferred whenever possible. Studies suggest that, in combination with scaling and planing, any of these approaches are very effective for periodontal health.

Several different topical applications are showing promise, including:

Atridox is a doxycycline gel that conforms to the gum surface and then solidifies. Over the next few days, it releases the antibiotics.
Elyzol is a gel or strip applied to the gum that is composed of metronidazole. It has unique actions that are effective against parasites as well as bacteria. Studies suggest that Atridox, which contains doxycycline, may be more effective than Elyzol. (In one study, however, the doxycycline gel worked faster, but metronidazole achieved a greater bacterial reduction.)
PerioChip is a chip that is placed into the gum pocket after scaling. Over time, it slowly releases chlorhexidine, a powerful bacteria-killing antiseptic. Early studies report benefits in reducing pocket depths, but it is still not known whether these improvements are sustained.
Minocycline microspheres (Arestin) contain antibiotics in tiny capsules, which are applied to the gums after scaling and planing. Studies report that they are more effective in reducing pocket depth and bone loss than standard periodontal maintenance. Patients obtain these benefits regardless of their smoking status, age gender, or extent of the periodontal disease.
Actisite is a thin strip similar to dental floss, which is treated with tetracycline hydrochloride. The treated thread is temporarily inserted between the tooth and gum. (Using multiple strips may be more beneficial than using a single strip.) This was one of the first topical applications of antibiotics. Other topical approaches are being increasingly used.

Subantimicrobial Dose Doxycycline (Periostat). Subantimicrobial dose doxycycline (SDD) is a term used for a treatment that uses very low doses (20 mg) of doxycycline (Periostat). Although doxycycline is a tetracycline antibiotic, the doses used are too low to affect bacteria. However, at these dose levels, the drug blocks matrix metalloproteinases (MMPs) -- enzymes that destroy the connective tissues holding the teeth. Periostat is taken twice a day for months. There is some concern that such long-term use may pose a risk for the development of antibiotic-resistant bacteria or other, still unknown, adverse effects. The doses used in this treatment, however, are too low to have any effect on bacteria, so some experts believe this risk is very low. In fact, several 12-month studies report significant improvements in tooth attachment and pocket depth with no increased incidence of side effects. [Taking a common nonsteroidal anti-inflammatory drug, such as aspirin or ibuprofen (Advil) along with doxycycline, may enhance the effectiveness of this treatment.]

Chemically Modified Tetracyclines. Other tetracyclines are being developed that inhibit MMPs but have no antibiotic properties, which would, theoretically, avoid possible long-term problems with antibiotic resistance.

Other Treatments

Nonsteroidal Anti-inflammatory Drugs (NSAIDs). NSAIDs are drugs that block factors that cause inflammation and pain.

Over-the-counter NSAIDs include aspirin, ibuprofen (Motrin IB, Advil, Nuprin, Rufen), naproxen (Aleve), ketoprofen (Actron, Orudis KT).
Prescription NSAIDs include naproxen (Naprosyn, Anaprox), diclofenac (Voltaren), tolmetin (Tolectin), ketoprofen (Orudis, Oruvail), indomethacin (Indocin).

These drugs are used not only for relieving pain in periodontal disease but also for slowing the disease process. NSAIDs block inflammatory enzymes triggered by cytokines, which are important immune factors in periodontal disease. A number of NSAIDs have been investigated and have been shown to reduce gingivitis and slow progression of periodontal disease.

In one study, long-term use of oral flurbiprofen (Ansaid) resulted in significantly lower bone loss, although disease progression returned when the drug was stopped.

Investigators are also studying rinses, creams, and other topical forms of NSAIDs. For example, a cream containing ketoprofen appears to reduce bone loss. (Ketoprofen is of particular interest because it blocks not only COX-2 but also another pathway involved in the disease process.)

Warning about NSAIDs: Although NSAIDs work well, long-term use can cause stomach problems, such as ulcers and bleeding, and possible heart problems. In April 2005, the FDA asked drug manufacturers of NSAIDs to include a warning label on their product that alerts users of an increased risk for cardiovascular events and gastrointestinal bleeding.

Gels containing growth factors -- including substances called recombinant human (rh), platelet-derived growth factor-BB (PDGF-BB), and (rh) insulin-like growth factor-I (IGF-I) -- are showing promise for restoring bone.

Research is underway to find a vaccine against periodontal disease. To date, animal studies show promise, but an effective vaccine for people is years away.

Researchers are investigating the use of photodynamic therapy (PDT) as an alternative to antibiotic drugs. PDT destroys periodontal bacteria by applying photosensitive drugs to oral regions and exposing the drug-treated area to a light or laser. Research appears promising but is still in its preliminary stages.

Sling Procedure Versus Burch Colposuspension

The sling procedure is better than Burch colposuspension in treating stress incontinence but may cause more post-operative urinary complications, according to results from an important 2007 New England Journal of Medicine study. In the first large-scale clinical trial to directly compare these two types of surgery, 47% of women who underwent the sling procedure had no urinary incontinence 2 years after surgery, compared with 38% of women who received the Burch procedure. However, 63% of women who had the sling procedure (and 47% of women who underwent the Burch procedure) experienced urinary tract infections following surgery.

Oxybutynin May Cause Hallucinations

In 2007, the FDA investigated reports that oxybutynin (Detrol) may cause hallucinations, especially in children and older adults. Out of 202 reports of oxybutynin-related central nervous system side effects, hallucinations occurred in 27% of cases involving children and 25% of cases involving adults age 60 years and older. The FDA is considering adding stronger cautions about these risks to oxybutynin’s prescribing label.

Tamsulosin and Tolterodine Combination Treatment

For men with moderate-to-severe lower urinary tract symptoms, including overactive bladder, a combination of tamsulosin (Flomax) and tolterodine (Detrol) works better than either drug alone, according to a study published in 2006 in the Journal of the American Medical Association.

Researchers Investigating Stem Cell Treatment for Stress Incontinence

Muscle stem cell injections may eventually prove to be an effective treatment for stress incontinence, indicate several small studies. Doctors took tissue biopsies from patients’ arm muscles, then isolated and injected the muscle stem cells into areas surrounding the urethra. The injections helped strengthen sphincter muscles and improved bladder control. Researchers presented results of these studies at the 2007 American Urological Association annual meeting and the 2006 Radiological Society of North America annual meeting.

Introduction

Urinary incontinence is the inability to control urination. It may be temporary or permanent, and can result from a variety of problems in the urinary tract. Urinary incontinence is generally divided into four groups, according to the problem involved:

Stress incontinence
Urge incontinence
Overflow incontinence
Functional incontinence

Often, more than one type of incontinence is present, with about 40% of all cases falling into more than one category.

Because incontinence is a symptom, rather than a disease, it is often hard to determine the cause. In addition, a variety of conditions may be the cause.

The urinary system helps to maintain proper water and salt balance throughout the body:

The process of urination begins in the two kidneys, which process fluids and dissolve waste matter to produce urine.
Urine flows out of the kidneys into the bladder through two long tubes called ureters.
The bladder is a sac that acts as a reservoir for urine. It is covered with a membrane and enclosed in a powerful muscle called the detrusor. The bladder rests on top of the pelvic floor. This is a muscular structure similar to a sling running between the pubic bone in front to the base of the spine.
The bladder stores the urine until it is eliminated from the body via a tube called the urethra, which is the lowest part of the urinary tract. (In men it is enclosed in the penis. In women it leads directly out.)
The connection between the bladder and the urethra is called the bladder neck. Strong muscles called sphincter muscles encircle the bladder neck (the smooth internal sphincter muscles) and urethra (the fibrous external sphincter muscles).

The Process of Urination

The process of urination is a combination of automatic and conscious muscle actions. There are two phases: the emptying phase and the filling and storage phase.

The Filling and Storage Phase. When a person has completed urination, the bladder is empty. This triggers the filling and storage phase, which includes both automatic and conscious actions.

Automatic Actions. The automatic signaling process in the brain relies on a pathway of nerve cells and chemical messengers (neurotransmitters) called the cholinergic and adrenergic systems. Important neurotransmitters include serotonin and noradrenaline. This pathway signals the detrusor muscle surrounding the bladder to relax. As the muscles relax, the bladder expands and allows urine to flow into it from the kidney. As the bladder fills to its capacity (about 8 - 16 oz of fluid) the nerves in the bladder send back signals of fullness to the spinal cord and the brain.
Conscious Actions. As the bladder swells, the person becomes conscious of a sensation of fullness. In response, the individual holds the urine back by voluntarily contracting the external sphincter muscles, the muscle group surrounding the urethra. These are the muscles that children learn to control during the toilet training process.

When the need to urinate becomes greater than one's ability to control it, urination (the emptying phase) begins.

The Emptying Phase. This phase also involves automatic and conscious actions.

Automatic Actions. When a person is ready to urinate, the nervous system initiates the voiding reflex. The nerves in the spinal cord (not the brain) signal the detrusor muscles to contract. At the same time, nerves are also telling the involuntary internal sphincter (a strong muscle encircling the bladder neck) to relax. With the bladder neck now open, the urine flows out of the bladder into the urethra.
Conscious Actions. Once the urine enters the urethra, a person consciously relaxes the external sphincter muscles, which allows urine to completely drain out from the bladder.

The female and male urinary tracts are relatively the same except for the length of the urethra.

Stress Incontinence

The primary symptom of stress incontinence is leakage due to activities that apply pressure to a full bladder. High-impact exercise poses the greatest risk for leaking. But stress incontinence can occur with even minor activities, such as:

Coughing
Sneezing
Laughing
Running (sometimes even standing can produce leakage)
Lifting

Leakage stops when the activity stops. If the condition persists, it is more likely to be urge incontinence.

Stress incontinence occurs because the internal sphincter does not close completely. In both men and women, the aging process causes a general weakening of the sphincter muscles and a decrease in bladder capacity. Causes of stress incontinence, however, may differ between men and women.

In women, stress incontinence is nearly always due to one or both of the following:

The urethra fails to close and becomes overly movable (urethral hypermobility).
The muscles around the bladder neck weaken (intrinsic sphincteric deficiency or ISD). Some experts believe that this problem is present to some degree in nearly all women with stress incontinence. (ISD can also occur in anyone from an inborn disorder or injury from surgery or radiation.)

Many women are prone to one or both of these problems, which can occur under the following circumstances:

Having had many children through vaginal deliveries. In such cases, pregnancy and childbirth strain the muscles of the pelvic floor. Prolapsed uterus, in which the uterus protrudes into the vagina, occurs in about half of all women who have given birth. This condition can often cause incontinence.
Menopause. Estrogen deficiencies after menopause can cause the urethra to thin out so that it may not close properly.

Urethral Hypermobility. In urethral hypermobility the urethra does not close properly, allowing it to move too much (hypermobile). This condition typically occurs when the pelvic floor muscles in women become weak, and the following events occur:

The weakened pelvic floor muscles stretch.
This allows the bladder to sag downward within the abdomen.
The sagging bladder pulls on the muscles surrounding the bladder neck (internal sphincter), which are connected to the urethra.

Stress incontinence associated with urethral hypermobility is sometimes categorized as type 1 or type 2.

Type 1 is the less severe form, and the bladder neck and urethra remain incompletely closed.
In type 2, the angle of the bladder neck shifts. In such cases cystocele may occur, in which the bladder muscles bulge (herniate) into the vaginal wall.

Intrinsic sphincteric deficiency (ISD). Intrinsic sphincter deficiency (sometimes called type 3) is the other major cause of stress incontinence in women. It occurs when the bladder neck muscles are damaged or weakened. The result is twofold:

The bladder neck is open during filling.
The closing pressure around the urethra is low.

This is the most severe stress incontinence in women and usually occurs after previous surgeries for incontinence.

Prostate treatments can impair the sphincter muscles. Such treatments are the major causes of stress incontinence in men. They include the following:

Surgery or radiation for prostate cancer. Incontinence occurs in nearly all male patients for the first 3 - 6 months after radical prostatectomy. After a year of the procedure, most men retain continence, although leakage can occur.

Surgery for benign prostatic hyperplasia. Stress incontinence occurs in 1 - 5% of men after transurethral resection of the prostate (TURP), the standard treatment for severe benign prostatic hyperplasia.

Click the icon to see an illustrated series detailing TURP surgery.

Incontinence after prostate procedures is often a combination of urge and stress. Because studies often combine the two types of incontinence, it is not always clear which predominates.

Urge Incontinence

The main symptom of urge incontinence (also called hyperactive, irritable, or overactive bladder) is the need to urinate frequently. Patients may go to the bathroom more than 8 times over 24 hours, including 2 or more times a night, and have subsequent leakage. However, most people (60%) with overactive bladder experience only urgency and frequency. In some cases, urge incontinence occurs only at night. This is called nocturnal enuresis.

All cases of urge incontinence involve an overactive bladder. This occurs when the detrusor muscle, which surrounds the bladder, contracts inappropriately during the filling stage. When this occurs, the urge to urinate cannot be voluntarily suppressed, even temporarily. There is usually one of two types:

Idiopathic Detrusor Overactivity (formerly called Detrusor Instability). In this type, the nerves serving the bladder have signaled the brain appropriately that the bladder is full, but the detrusor muscles are unable to be suppressed. The actual cause, however, is not known.
Neurogenic Detrusor Overactivity (formerly called Detrusor Hyperreflexia). With this type, a known neurologic abnormality impairs the signaling systems between the bladder and the central nervous system, and the brain is unable to inhibit the detrusor muscles controlling urination.

Very often, the cause of detrusor instability and bladder hyperactivity is unknown. Some conditions that can produce the disorders leading to urge incontinence include the following:

Benign prostatic hyperplasia (BPH). Detrusor instability occurs in about 75% of men with BPH and causes frequency, urgency, and urination during the night (although incontinence itself occurs only in very severe cases). Urge incontinence only at night can be a sign of severe obstruction in the urinary tract.

Benign prostatic hypertrophy (BPH) is a non-cancerous enlargement of the prostate gland, commonly found in men over the age of 50.

Prostate surgical procedures. Either prostatectomy for prostate cancer or transurethral resection of the prostate (TURP) for BPH can cause detrusor instability. As with stress incontinence, prostatectomy poses a much higher rate than with TURP, which is very low.
Hysterectomy. Complications of this operation, which removes the uterus, are associated with a higher risk for urge incontinence. In one study, for example, incontinence developed or worsened after hysterectomy in about 16% of women who had only mild or no incontinence before surgery. However, hysterectomies can also significantly improve urinary incontinence in many women who have an existing condition before the procedure. In the same study, 30% of women had severe urinary incontinence before hysterectomy, which declined to 20% afterward and was sustained for at least 2 years.

Damage to the central nervous system. Certain neurologic disorders or injuries can disrupt the passage of nerve messages between the urinary tract and central nervous system. These neurological conditions include stroke, multiple sclerosis, spinal cord or disk injury, and Parkinson's disease.
Infections.
The aging process.
Emotional disorders. Anxiety and possibly even depression have been associated with urge incontinence.
Medications, including some sleeping pills.
Genetic factors may play a role in some cases.

Overflow Incontinence

Overflow incontinence happens when the normal flow of urine is blocked and the bladder cannot empty completely. Overflow incontinence can be due to a number of conditions:

A partial obstruction. In this case the urine cannot flow completely out of the bladder, so it never fully empties.
An inactive bladder muscle. In contrast to urge incontinence, the bladder is less active than normal, not more. It cannot empty properly and so becomes distended, or swells. Eventually this distention stretches the internal sphincter until it opens partially and leakage occurs.

The causes of the conditions leading to overflow incontinence include:

Tumors
Certain medications (anticholinergics, antidepressants, antipsychotics, sedatives, narcotics, alpha-adrenergic agonists, beta-adrenergic agonists, calcium channel blockers)
Benign prostatic hyperplasia (enlarged prostate)
Scar tissue
Nerve damage. In such cases, nerves in the bladder are damaged so that the body cannot feel when the bladder is full, and the bladder does not contract. Such damage can be caused by spinal cord injuries, previous surgery in the colon or rectum, and pelvic fractures. Diabetes, multiple sclerosis, and shingles also can cause this problem.

Functional Incontinence

Patients with functional incontinence have mental or physical disabilities that keep them from urinating, although the urinary system itself is normal. Conditions that can lead to function incontinence include:

Parkinson's disease.
Alzheimer's disease and other forms of dementia. Mental confusion may prevent both recognition of the need to void and locating a bathroom.
Severe depression. In such cases, people may become incontinent because they are indifferent to self-control.

Risk Factors

About 13 million adults experience incontinence at some time. The number, however, may actually be higher because most patients are reluctant to discuss incontinence with their doctors. In fact, research indicates that many patients will not admit to having the problem even when questioned directly. Although a third of American men and women age 30 - 70 have experienced at least some loss of bladder control, most have not been diagnosed by a doctor.

A 2004 survey of more than 1,400 Americans found that despite the prevalence of bladder control loss, an alarming 64% of those experiencing symptoms are not currently taking measures to manage their condition. The survey, sponsored by the National Association for Continence, also found that adults waited an average of 6 years before discussing their symptoms with a doctor. A 2006 study reported that only half of women with urinary incontinence have discussed their condition with a doctor, while only a third had received any treatment.

Incontinence is uncommon in children 5 years and older. However, it may still occur in:

10% of 5 year-olds
5% of 10 year-olds
1% of 18 year-olds

Incontinence that occurs before puberty is twice as common in boys as in girls. Most young people who experience nighttime wetting do not have any serious physical or emotional disorders. It is often difficult to diagnose incontinence in children. Many cases result from a combination of factors, including:

Birth defects or inborn conditions that cause problems in the urinary tract
Slower physical development
An overproduction of urine at night
A lack of ability to recognize bladder filling when asleep
Anxiety
Inherited factors (indicated by a strong family history of bedwetting)

Bedwetting in children is not considered incontinence. However, bedwetting and other urinary problems in childhood may predict the later development of adult urinary incontinence. According to a 2006 study, women who experienced childhood bedwetting, as well as frequent daytime and nighttime urination, had an increased risk of developing adult urge incontinence.

All older adults are susceptible to incontinence. One in 10 people over age 65 have some type of bladder control loss. About 12% of women ages 60 - 64 and 21% of women age 85 and over experience daily urinary incontinence. About half of the elderly who are housebound or in nursing homes experience incontinence.

Urinary incontinence is far more common among women than men. Between 15 - 50% of women experience urinary incontinence during their lifetimes, with the highest rates occurring in women who have had children. Severe urinary continence affects 7 – 10% of women. About 10% of women undergo surgery for urinary incontinence or pelvic organ prolapse.

Birth Conditions. Pregnancy and childbirth may increase the risk for urinary incontinence. The risk is highest with the first child, and there is an increased risk in women who have their first child over age 30. Some studies suggest that women who used the drug oxytocin for inducing labor are at higher risk for developing urinary incontinence. Such medically induced labor tends to subject the muscles and nerves in the pelvis to greater force than does natural labor.

Studies indicate that the method of birth can affect risk later in life. For example, a major 2003 study reported that women who had a cesarean section had a much lower risk for stress incontinence before age 50 than women who had vaginal delivery. However, a 2006 study contradicted many assumptions by suggesting that vaginal delivery is not associated with later development of urinary incontinence in postmenopausal women. The study compared sisters who had either given birth vaginally or had never had children. Researchers found no difference in rates of urinary incontinence. The study suggested that cesarean delivery may not make much difference in preventing urinary incontinence.

Another 2006 study found that episiotomy does not help prevent urinary incontinence. Episiotomy is a surgical incision that is made during childbirth to the perineum, the muscle between the vagina and the rectum. Doctors commonly perform this procedure to help widen the vaginal opening and prevent tearing. The study found that episiotomy does not have many benefits, and may later cause pain during intercourse.

Vaginal birth can cause pelvic prolapse, a condition in which pelvic muscles weaken and the pelvic organs (bladder, uterus) slip into the vaginal canal. Pelvic prolapse, and the surgery used to correct it, can cause incontinence. Sacrocolpopexy is the standard surgical procedure for repairing pelvic prolapse. A 2006 study found that performing a urinary incontinence surgical procedure (Burch colposuspension) at the same time as sacrocolpopexy can help prevent stress incontinence. [See Surgery section.]

High-Impact Exercise. Women who engage in high-impact exercise are susceptible to urinary leakage, particularly women with a low foot arch. Shock to the pelvic area is increased as the foot makes impact with hard surfaces. Those at highest risk for urinary leakage are gymnasts, followed by softball, volleyball, and basketball players.

Smokers. Studies have reported a higher risk for incontinence, notably mixed incontinence, in women who are current or former heavy smokers (more than a pack a day).

Obesity. Being overweight is a major risk factor for all types of incontinence. The more a woman weighs, the greater her risk.

Medical Factors in Older Women. Urge incontinence is more common among postmenopausal women who have a history of:

Diabetes
Higher body mass index (heavier weight)
Hysterectomy
Two or more urinary tract infections within the past year

The rate of incontinence in men (about 1.5 - 5%) is much lower than in women. The risk for urinary incontinence increases with age. In the United States, about 17% of men over age 60 have urinary incontinence. In older men, prostate problems and their treatments are the most common factors that affect the urinary tract. Up to 30% of men who have had surgery to remove their prostate gland experience some degree of urinary incontinence.

Urinary incontinence varies by race and ethnicity. It is most common in non-Hispanic white women. Among men, African-Americans are at highest risk. Some studies suggest that the greatest disparity is with stress incontinence. African-American and Asian American women have a much lower risk for stress incontinence than Caucasian and Hispanic women.

A number of conditions can cause temporary incontinence in anyone:

Urinary tract infections
Excess fluid intake
Constipation
Severe depression
Restricted mobility

Drugs. Drugs are most often the cause of temporary incontinence.

Drugs that affect the adrenergic system (a nerve-cell and hormonal pathway that regulates the sphincter muscle) are common causes of incontinence. For example, alpha-adrenergic blockers, such as terazosin (Hytrin), used for benign prostatic hypertrophy, can cause incontinence by over-relaxing the muscles. On the other hand, men with enlarged prostates who suffer from urinary problems may be helped by the increase of urine flow after using terazosin.
Alpha-adrenergic agonists, such as pseudoephedrine (found in some oral decongestants) strengthen the muscles and may cause overflow incontinence in susceptible people.
Beta-adrenergic blockers, such as propranolol (Inderal), prescribed for hypertension and angina, relax the sphincter.
Diuretics, used for high blood pressure, often rapidly introduce high urine volumes into the bladder.
Calcium-channel blockers can cause overflow incontinence by relaxing the bladder detrusor muscles.
Colchicine, a drug used for gout, can cause urge incontinence.
Other medications and substances that increase the risk for incontinence are caffeine, sedatives, antidepressants, antipsychotics, and antihistamines.

Diagnosis

Fewer than half of the patients who have urinary incontinence tell their doctor about the problem. In many cases, patients simply feel that incontinence is part of the aging process. And, in spite of the commonness of this problem, two-thirds of doctors never ask their older patients if they experience incontinence.

It is important, however, for both the doctor and the patient to raise the issue.

The first step in the diagnosis of incontinence is a detailed history. The doctor should ask questions about the patient's present and past medical conditions and patterns of urination. Patients should tell the doctor the following information:

When the problem began
Frequency of urination
Amount of daily fluid intake
Use of caffeine or alcohol
Frequency and description of leakage or urine loss, including activity at the time, sensation of urge to urinate, and approximate volume of urine lost
Frequency of urination during the night
Whether the bladder feels empty after urinating
Pain or burning during urination
Problems starting or stopping the flow of urine
Forcefulness of the urine stream
Presence of blood, unusual odor or color in the urine
A list of major surgeries with their dates, including pregnancies and deliveries, and other medical conditions
Any medications being taken

A 2006 study suggested a simpler way of diagnosing incontinence using a test that asks 3 questions:

During the last 3 months, have you leaked urine (even a small amount)?
When did you leak urine? (During physical activity; when you could not reach the bathroom quickly enough; without physical activity or bladder urge.)
When did you leak urine most often? (Physical activity; bladder urge; without or about equally with physical activity or bladder urge.)

Based on the patient’s answers, the “3IQ” test may help a doctor distinguish between urge and stress urinary incontinence.

Voiding Diary. The patient might find it helpful to keep a diary for 3 to 4 days before the office visit. This diary, sometimes referred to as a voiding diary or log, should be a detailed record of:

Daily eating and drinking habits
The times and amounts of normal urination

For each incident of incontinence, the log should also detail:

The amount of urine lost (the patient is often asked to catch and measure urine in a measuring cup during a 24-hour period)
Whether the urge to urinate was present
Whether the patient was involved in physical activity at the time

The office visit should consist of a thorough physical examination, checking for abnormalities or enlargements in the rectal, genital, and abdominal areas that may cause or contribute to the problem.

One of the important measurements for urinary incontinence is the postvoid residual urine volume (PVR). This is the amount of urine left in the bladder after urination:

Normally, about 50 mL or less of urine is left
More than 100 mL suggests an abnormality and requires further tests
More than 200 mL is a definite sign of abnormalities

Use of a Catheter. The most common method for measuring PVR uses a catheter, which is inserted into the urethra after a few minutes of urination. The advantage of the catheter is that it can also collect urine for analysis.

Ultrasound. Ultrasound is useful in determining the volume of urine.

Cystometry measures the bladder's ability to retain urine at different capacities and pressures. It uses a catheter and can be performed at the same time as the PVR test.

Subtraction Cystometry. Although procedures vary, the basic steps for the technique are as follows:

The patient empties the bladder as much as possible.
Two catheters are inserted into the urethra until they reach the bladder. One is used to fill the bladder with water. The other is used to measure pressure. Another catheter is inserted into the rectum or vagina, which is used to measure abdominal pressure.
While water is instilled through the tube into the bladder, the pressure in the bladder and abdomen are measured and the results are recorded in a computing device.
During the process, the patient informs the doctor about any changes in the need to urinate, including the initial need to urinate, a normal desire to urinate, and a strong need to urinate.
Often during this process, the patient is asked to cough, bounce up and down, or even walk in place. The patient may also be asked to strain as if he or she is having a bowel movement. This is called the Valsalva maneuver. The point at which leakage occurs during this action is called the Valsalva leak point pressure, which might be a useful measurement for determining treatment.
When the urge to urinate is strong, the doctor stops this portion of the test.
A calculation is then made using bladder and abdominal pressure measurements as well as volume and flow rate of the urine. The result provides the doctor with an assessment of detrusor contractions.

The detrusor muscles of a normal bladder will not contract during bladder filling. Severe contractions at low amounts of administered fluid (less than 200 mL) indicate urge incontinence. Stress incontinence is suspected when there is no significant increase in bladder pressure or detrusor muscle contractions during filling, but the patient experiences leakage if abdominal pressure increases.

Video Cystometry. Video cystometry combines a computer reading of bladder pressures and pictures of the bladder itself. It is most useful in cases where the more standard tests have not yielded satisfactory results.

To determine whether the bladder is obstructed, the speed of urine flow is measured electronically using a test called uroflowmetry. The test involves the following steps:

Patients are instructed not to urinate for several hours before the test and to drink plenty of fluids so they have a full bladder and a strong urge to urinate.
To perform this test, a patient urinates into a special toilet equipped with a uroflowmeter.
It is important that patients remain still while urinating to help ensure accuracy, and that they urinate normally and do not exert strain to empty their bladder or attempt to retard their urine flow.

Many factors can affect urine flow (such as straining or holding back because of self-consciousness) so experts recommend that the test be repeated at least twice.

Q[max]. The rate of urine flow is calculated as milliliters of urine passed per second (mL/s). At its peak, the flow rate measurement is recorded and referred to as the Q[max]. The higher the Q[max], the better the patient's flow rate. Men with a Q[max] of less than 12 mL/s have four times the risk for urinary retention than men with a stronger urinary flow.

The Q[max] measurement is sometimes used as the basis for determining the severity of obstruction and for judging the success of treatments. It is not very accurate, however, for a number of reasons:

Urine flow varies widely among individuals as well as from test to test.
The patient's age must be considered. Flow rate normally decreases as men age, so the Q[max] typically ranges from more than 25 mL/s in young men to less than 10 mL/s in elderly men.

The Q[max] level does not necessarily coincide with a patient's perceptions of the severity of his own symptoms.

Urethrocystoscopy. Urethrocystoscopy, also called cystourethroscopy or cystoscopy, detects structural abnormalities, inflammation of the bladder wall, or masses that might not show up on x-ray.

The patient is given a light anesthetic, and the bladder is filled with water.
Next, a thin flexible tube called a cystoscope is inserted through the urethra into the bladder.
The end of the cystoscope contains a tiny microscope-like instrument.
The doctor uses the cystoscope to look for abnormalities in the interior of the bladder.

Cystoscopy is a procedure that uses a flexible fiber optic scope, which is inserted through the urethra into the urinary bladder. The doctor fills the bladder with water and inspects the interior of the bladder. The image seen through the cystoscope may also be viewed on a color monitor and recorded on videotape for later evaluation.

The procedure has some risks. Complications are uncommon, but can include allergic response to the anesthetic, urinary tract infection, bleeding, and urine retention.

Intravenous Pyelogram. Intravenous pyelogram (IVP) may be used to diagnose urge incontinence. It is performed as follows:

A dye is injected into the patient's vein and is processed by the kidneys.
A series of x-ray pictures are taken of the kidneys, ureter, and bladder as the dye passes through them. This provides a dynamic picture of the relationship between the patient's urinary system and urinary functioning.

Click the icon to see an image of an intravenous pyelogram.

IVPs can detect structural abnormalities, urethral narrowing, or incomplete emptying of the bladder. This test should not be used on pregnant women or patients with kidney failure. There is a risk for an allergic reaction to standard dyes, although newer, less allergenic ones are becoming available.

Ultrasound. Ultrasound plays a role in many cases of incontinence. For example, it is useful for men with prostate problems. It is helpful in measuring urine volume in the bladder. Ultrasound may also be useful in many cases of female stress incontinence, by identifying abnormalities in the bladder neck, and in assessing the urinary tract before and after surgery. It also may eventually be useful in diagnosing detrusor instability.

Chain Cystogram. In cases of stress incontinence, a chain cystogram may also be performed. With this procedure, a beaded chain is positioned in the bladder and urethra. The x-ray image of the chain reveals the angle of the bladder neck. This test should not be performed on pregnant women.

Electrophysiologic sphincter testing, also referred to as electromyography (EMG), evaluates two important factors:

The function of the nerves serving the sphincter and pelvic floor muscles.
The patient's ability to control these muscles.

Using a technique similar to that of an electrocardiogram, the doctor places electrodes on the affected areas to observe electrical activity in the muscles.

Urethral pressure profile is used to investigate urethral blockage. A probe is placed in the urethra to determine pressure at different points along this pathway during urination and the exact location of any obstruction in the urethra.

Prognosis

Incontinence is rarely life threatening. In most cases, if treated promptly, physical complications are not serious.

Urinary incontinence can have severe emotional effects. Depression is very common in women with incontinence. For example, in a 2003 study, 82% of women with severe incontinence and 41% of those with moderate incontinence reported at least 2 weeks of depression during the preceding year. Incontinence also has emotional effects on men. A number of studies of prostate cancer patients suggest that incontinence is a much more distressing side effect for men than impotence (also a side effect of prostate cancer treatment).

Other negative emotional effects reported include:

Loneliness and humiliation. Because little public attention has been paid to this problem, the incontinent person often feels alone and humiliated. Many people with incontinence do not even seek medical advice for the problem. In one survey of doctors, nearly all of them reported that a patient's embarrassment and reluctance to discuss bladder problems is a major barrier to successful treatment.
Shame. Many people experience a sense of personal failure.
Helplessness. Patients often feel helpless and angry.
Introversion. Patients may eventually curtail social activities, or even give them up entirely.
Lack of confidence. Many people with incontinence believe that they are unemployable.

To prevent humiliation due to wetness or odors, people with incontinence may have to alter their way of life.

Errands become very difficult and need advanced planning.
Public bathrooms may difficult to locate or unavailable. The problem is particularly severe for those with urge incontinence who have little time to reach a bathroom and have large volume spills.

Incontinence is particularly serious in older adults:

Older adults who are otherwise healthy may stop exercising because of leakage, which can increase their impairment.
Incontinence can result in loss of independence and quality of life.
It is a major reason for nursing home placement.
Severe incontinence may require catheterization. This is the insertion of a tube that allows urine to continually pass into an external collecting bag. In such cases, complications are common, particularly infections.
There is a strong association between urge incontinence and falls and injuries. In one large study, over half of women who reported incontinence experienced at least one fall over a 3-year period. This high incidence of falls may be due in part to the rush to the toilet in the middle of the night. Keeping a pan or portable commode near the bed may prevent injuries as well as improve sleep and general convenience.

Treatment

The treatment for temporary incontinence can be rapid, simple, and effective. If urinary tract infections are the cause, they can be treated with antibiotics. Any related incontinence will often clear up in a short time. Medications that cause incontinence can be discontinued or changed to halt episodes.

Chronic incontinence may require a variety of treatments, depending on the cause. Treatment options are listed below in the order in which they are usually tried, from least-to-most invasive:

Behavioral techniques, which include Kegel exercises and bladder training, are sometimes all a person needs for achieving continence. A number of devices can also be used to strengthen muscles and prevent urine leakage. Bladder training is useful for urge incontinence.
Medications are tried next. These may include anticholinergics and antispasmodics. Estrogen or estrogen plus progesterone used to be recommended, but recent research has shown that these hormone treatments can actually make urinary incontinence worse.
Surgery. Surgery is the last resort; there are many effective procedures available for stress incontinence.

Lifestyle techniques to improve quality of life and improve hygiene are part of all treatments.

Lifestyle measures, including dietary recommendations, bladder training, and continent aids, are useful for anyone with incontinence. Other treatments vary depending on whether the patient has stress or urge incontinence. In people who have both, the treatment usually is aimed at the predominant form.

Treating Stress Incontinence. The general goal for women with stress incontinence is to strengthen the pelvic muscles. Typical steps for treating women with type 1 stress incontinence are:

Devices and continent aids for blocking urine in the urethra (vaginal pessaries, adhesive pads, and others).
Behavioral techniques and noninvasive devices, including Kegel exercises, weighted vaginal cones, and biofeedback.
Medications. Alpha-adrenergic agonists and possibly tricyclic antidepressants.
Surgery is a reasonable option if symptoms do not improve with noninvasive methods. Many are available, and most are designed to restore the bladder neck and urethra to their anatomically correct positions.

Treating Urge Incontinence. The goal of most treatments for urge incontinence is to reduce the hyperactivity of the bladder. The following methods may be helpful:

Behavioral methods
Medications (anticholinergics, anti-spasmodics, and alpha blockers)
Procedures that stimulate the pelvic floor or nerves in the tailbone (the sacral nerves), which help retrain the bladder

Lifestyle Changes

Many products are now available that help patients avoid embarrassment and, in some cases, prevent leakage. With recent improvements in paper technology, pads are now thin enough to be worn undetected, and a spare can be hidden in a purse or pocket. Proper hygiene is also essential for patients with incontinence.

Keeping Skin Clean. To avoid skin irritation and infection associated with incontinence, keep the area around the urethra clean. The following tips may be helpful:

After a urinary accident, clean any affected areas right away.
When bathing, use warm water and don't scrub forcefully; hot water and scrubbing can injure the skin.
A number of cleansers are available that are specially created for incontinence and allow frequent cleansing without over-drying or causing irritation to the skin. Most do not have to be rinsed off; the area is simply wiped with a cloth.
After bathing, a moisturizer plus a barrier cream should be applied. Barrier creams include petroleum jelly, zinc oxide, cocoa butter, kaolin, lanolin, or paraffin. These products are water repellent and protect the skin from urine.
Anti-fungal creams that contain miconazole nitrate are used for yeast infections.

Preventing or Reducing Odor. Certain methods may help reduce odor from accidents. They include:

Deodorizing tablets, such as Derifil, Nullo, Devrom, and Chlorofresh can be taken by mouth or used in appliances. Most contain chlorophyll.
Taking an alfalfa pill four times a day may reduce odor, and is not believed to interfere with any other medications. Alfalfa is a common grass, and some people with seasonal allergies may experience an allergic reaction. Talk to your doctor before taking any type of supplement.
Drinking more water, not less, will also reduce odors. Drinking more water may actually help reduce leakage, too.
To remove odors from mattresses, some experts recommend a solution of equal parts vinegar to water. Once the mattress has dried, baking soda can be applied on the stain, rubbed in, and then vacuumed off.

Weight Control. In women, pelvic floor muscle tone weakens with significant weight gain, so women are urged to eat healthy foods in moderation and to exercise regularly.

Fluid Intake. A common misconception among people with incontinence is that drinking less water will prevent accidents. In reality, limiting fluid intake has the following effects:

The lining of the urethra and bladder becomes irritated, which may actually increase leakage.
Concentrated urine also has a stronger pungency, so drinking plenty of fluids can help reduce odor.

Some experts recommend drinking two to three quarts a day.

Drinking plenty of cranberry juice may be particularly helpful. It is known to help prevent urinary tract infections. (Low calorie juices are available.)

People with incontinence, however, should stop drinking beverages 2 - 4 hours before going to bed, particularly those who experience leakage or accidents during the night.

Fiber-Rich Foods. Constipation can worsen urinary incontinence, so diets should be high in fiber, fruits, and vegetables.

Fluid and Food Restrictions. A number of foods and beverages may increase incontinence. Some experts suggest that people who eat or drink the following items should try eliminating one a day over a 10-day period and check to see if removing them improves continence:

Caffeinated beverages. (In one major 2003 study, tea drinking -- but not coffee drinking -- was associated with incontinence. In general, however, it might be useful to try avoiding coffee as well, including decaf coffee.)
Carbonated beverages such as soda
Alcoholic beverages
Citrus fruits and juices
Tomatoes and tomato-based foods
Spicy foods
Chocolate
Sugars and honey
Artificial sweeteners
Milk and milk products

Some otherwise healthy adults stop exercising because of leakage. There are a number of methods for preventing or stopping leakage during exercise. The following are some tips:

Limit fluid intake before exercising (but be sure not to become dehydrated)
Urinate frequently, including right before exercise
Women can try wearing pads or urethral inserts

A variety of absorbent pads and undergarments are quite effective in catching spills and leaks. Many undergarments developed for incontinence are almost indistinguishable from regular briefs and underpants.

For women, the following are available:

Normal and even attractive looking washable underwear that contains waterproof panels is available for women. Even stomach-control panties are available for women with incontinence.

For men, the following are available:

Drip collectors are available which can be worn under briefs and are not noticeable under normal clothing. Lined with absorbent material, the pouch-like collector surrounds the penis or scrotum and is fastened with a belt or pins.
Washable briefs made from polyester have a fully functional fly and waterproof panel and look and feel like normal underwear. Boxer shorts are also available that look regular but have a protective pouch.

Even for men and women with severe incontinence, disposable undergarments can be purchased that have a normal look to them.

All absorbent undergarments should be changed when wet to limit problems of chafing or infection.

A specially shaped plastic urinal (Feminal) is available for women. It avoids the use of a bedpan, and can be used while the woman is lying down, seated, or even standing.

Urinals for men are available that attach to athletic-like supporters.

Other Treatments

Foam pads (Miniguard, UroMed, Impress, Softpatch) with an adhesive coating have been developed for women with stress incontinence. They work as follows:

The pad is placed over the opening of the urethra where it creates a seal, preventing leakage.
It is removed before urinating and replaced with a new one afterwards.
The pad can be worn up to 5 hours a day and through the night.
It can be used during physical activity, although it may change position during vigorous exercise.
It should not be worn during sexual intercourse.

In one study of women who used these products, the average number of leaks per week dropped from 14 to 5. Women with more severe incontinence (an average of 34 leaks a week) had only 10 events, and when leakage occurred, it was slight.

Adhesive pads should not be used by women with the following conditions:

Urinary tract or vaginal infections
Urge or other forms of nonstress incontinence
A history of surgery for incontinence

Urethral Shields. Shields or caps (CapSure, Bard Cap Sure, FemAssist) that fit over the urethral opening are safe and effective in managing many forms of incontinence.

In a study of patients with stress incontinence, CapSure reduced urine loss by 96% within a week, and 82% of patients were completely dry. Side effects include irritation and urinary tract infections, although they are not severe.
In another study, 47% of women who used FemAssist reported complete continence, and 33% of the women reported continence was improved by more than half. FemAssist offered equal benefits for women with stress, urge, or mixed incontinence.

Urethral Tubes or Sleeves. Tubes or sleeves (Reliance Urinary Control Device, FemSoft) that fit into the urethra are also available for female incontinence.

The Reliance Urinary Control Device for women is a small tube inserted into the urethra using a reusable syringe. The device must be prescribed by a doctor, who measures the woman's urethra to determine the right size. The tip of the tube contains a balloon that is inflated against the urethra and blocks urine, preventing leakage. Every time a woman urinates, she pulls a string that deflates the balloon, then throws the old device away and replaces it with a new one. It is effective, but carries a high risk for urinary tract infections and most women report discomfort and irritation.
FemSoft is a silicone tube insert surrounded by a liquid-filled sleeve. When the tube is inserted into the urethra, the sleeve conforms to its shape and creates a seal at the bladder neck, preventing leakage. It is intended for one-time use and is replaced after voiding. This is a relatively new product and information is lacking on its comfort and risk for urinary tract infections.

Vaginal Devices. Devices that support the vaginal wall also help support the urethra that is located next to it:

Tampons. Mild stress incontinence in women, particularly when induced by exercise, may be managed by using a tampon. Specially designed tampons (such as the Contrelle Continence Tampon) are available, but even simple menstrual tampons may be helpful. (Keep in mind that tampons can only be worn for a few hours.) As tampons push on the vaginal wall, it compresses the urethra. In one study, 86% of women with mild incontinence remained continent during exercise sessions when using tampons. Out of this group, however, only 29% with severe incontinence remained dry.
Vaginal Pessaries. Vaginal pessaries are devices inserted into the vagina that support the inside of the vaginal walls. Pessaries are usually made of silicon and come in various forms, including donut or cube-shapes. They must be fitted by a health professional and are effective for vaginal prolapse or other vaginal structural problems. Serious complications are rare but can occur if the pessary is not replaced periodically.
Introl Bladder Neck Support. The Introl bladder neck support prosthesis is a flexible ring that is inserted into the vagina and has two ridges that press against the walls, supporting the urethra. Sizing the Introl is difficult, but success rates of 83% have been reported in women with stress incontinence. It can be left in during urination but must be removed and cleaned afterward. Introl can cause vaginal or urethral infections and may also be uncomfortable.

Behavioral Treatments

With the exception of functional incontinence, most cases of incontinence will almost always improve with behavioral techniques. There are a variety of methods, but the focus is usually on strengthening or retraining the bladder. Studies indicate that such exercises are very effective, even for men recovering from surgery for prostate cancer.

To enhance bladder training for incontinent patients who are in nursing rooms, nurses may need to check patients for dryness and regularly remind them to urinate. As an extra tip for older people with severe incontinence, keeping a pan or portable commode near the bed may prevent injuries from falling as well as improve general convenience.

Perhaps the best first-line approach for any form of incontinence is a combination of Kegel exercises and bladder training. In one study, women who used this combination approach experienced an average 50% reduction in incontinence episodes, with nearly 40% of them achieving complete continence. It was equally effective for urge, stress, or mixed incontinence.

Studies also report that between 50 - 75% of patients who perform only Kegel exercises experience a substantial improvement in their symptoms, including elderly people who have had the problem for years. A 2006 review suggested that Kegel exercises are especially helpful for women in their 40s and 50s who suffer from stress incontinence. The women participated in a supervised Kegel exercise program for at least 3 months.

Pelvic Floor Muscle (Kegel) Exercises. Kegel exercises are designed to strengthen the muscles of the pelvic floor that support the bladder and close the sphincters.

Stress incontinence is an involuntary loss of control of urine that occurs at the same time abdominal pressure is increased as in coughing or sneezing. It develops when the muscles of the pelvic floor have become weak.

Dr. Kegel first developed these exercises to assist women before and after childbirth, but they are very useful in helping to improve continence for both men and women. Kegel exercises are particularly useful for the following conditions:

Stress incontinence. Some experts believe that Kegel exercises should be the primary treatment for stress incontinence.
Urge incontinence. They can also be helpful for urge incontinence in cases that are not caused by nerve damage. In one study, 85% of women reported satisfaction with this program.

The general approach for learning and practicing Kegel exercises is as follows:

Since the muscles are sometimes difficult to isolate, the best method is to first learn while urinating. The patient begins to urinate and then contracts the muscle in the pelvic area with intention of slowing or stopping the flow of urine. Women should contract the vaginal muscles as well. They can detect this by inserting a finger inside the vagina. When the vaginal walls tighten, the pelvic muscles are being correctly contracted.
An alternate approach is to isolate the muscles used in Kegel contractions by sensing then squeezing and lifting the muscles in the rectum that are used in passing gas. (Again, women should contract the vaginal muscles as well.)
Patients should place their hands on their abdomen, thighs, and buttocks to make sure there is no movement in these areas while exercising.
In order to achieve success, some experts recommend performing two exercises that have different timing for the hold and release of the contraction. Both should be done regularly.
The first method is used for strengthening the pelvic floor muscles. The patient slowly contracts and lifts the muscles and holds for 5 seconds, then releases them. There is a rest of 10 seconds between contractions.
The second method is simply a quick contraction and release. The object of this exercise is to learn to shut off the urine flow rapidly.
In general, patients should perform 5 - 15 contractions, three to five times daily.

Some notes of caution:

Once learned, Kegel exercises should not be performed while urinating more than about twice a month, since this practice may eventually weaken the muscles.
In women, incorrect or overly vigorous exercises may cause vaginal muscles to tighten excessively, resulting in pain during sexual intercourse.
Over-exercise can also tire muscles and cause more leakage.
Incontinence will return to its original severity if these exercises are discontinued, so commitment to the program must be high and possibly life-long.
It may be several months before the patient sees significant improvement.

Bladder Training. Bladder training involves a specific, graduated schedule for increasing the time between urinations:

Patients start by planning short intervals between urinations, then gradually progressing with a goal of voiding every 3 - 4 hours.
If the urge to urinate arises between scheduled voidings, patients should remain in place until the urge subsides. At the time, the patient moves slowly to a bathroom. (In a small study, 73% of women with stress incontinence were helped by an absurdly simple and obvious movement: crossing the legs whenever a cough or sneeze was coming on.)

This system uses a set of weights to improve pelvic floor muscle control. The cones are inexpensive, relatively simple to use, and evidence suggests that they are as effective as Kegel exercises or electrostimulation:

The typical set includes five cones of graduated weights ranging from 20 grams (less than 1 ounce) to 65 grams (slightly over 2 ounces).
Starting with the lightest, the woman places the cone in her vagina while standing and attempts to prevent the cone from falling out. The muscles used to hold the cone are the same ones needed to improve continence.

As with standard Kegel exercises, frequent repetition is required, but most women will eventually be able to use the heavier weights and build up the ability to prevent stress and urge incontinence.

Women who are unable to learn Kegel muscle contraction and release with verbal instructions can be helped with the use of biofeedback:

Biofeedback uses a vaginal or rectal probe inserted by the patient that relays information to monitoring equipment.
The patient isolates the pelvic floor and bladder muscles and performs Kegel exercises.
The monitor emits auditory or visual signals that indicate how strongly the patient is contracting the proper pelvic floor muscles and how effectively the bladder muscles are being released.
The apparatus is designed for home use.

As with any Kegel exercise regimen, biofeedback must be used for several months before it is effective. In one major study, 75% of women with urge incontinence reported satisfaction with biofeedback, although women who were simply given verbal cues were even more satisfied (85%). A 2005 study of older women found that biofeedback worked better than oxybutynin (Ditropan) in controlling nighttime urge incontinence. Biofeedback that teaches control of pelvic muscles may even be very helpful in children who have daytime wetting, frequent urinary tract infections, or both.

A treatment called extracorporeal magnetic innervation therapy stimulates pelvic muscles to automatically perform Kegel exercises:

The patients stay fully dressed and sit on a special chair during the treatment.
Highly focused magnetic fields penetrate the pelvic area to stimulate the nerves.
Sessions are twice a week for about 6 weeks, although it may take more than 8 weeks to build up the muscles.

Studies report that patients experience fewer leaks, need fewer pads, and have fewer voiding episodes throughout the day and night. Comparison studies of magnetic therapy and sham (or "dummy") treatments are mixed, however, with some reporting no differences. More studies are needed to determine whether extracorporeal magnetic innervation therapy has any value.

Electrical stimulation of the pelvic floor muscles has been a common treatment for years. The procedure uses a probe inserted into the anus or vagina, which produces a contraction in the pelvic floor muscles. Success rates range from 50 - 90% for urge incontinence. (It may also be useful for some patients with stress incontinence.) A recent study regarding patient-adjusted intermittent electrostimulation in women with stress or mixed urinary incontinence using a new implanted stimulator found the concept promising. Researchers, however, encouraged further investigation regarding the effectiveness and safety of the technique. The procedure requires frequent visits, and it takes 2 - 3 months before the patient feels the benefits. It is often not covered by insurance. Side effects can be distressing and include abdominal cramps, diarrhea, bleeding, and infection.

Medications

A number of medications are available that increase sphincter or pelvic muscle strength or relax the bladder, improving the ability to hold more urine. Medications are prescribed for all kinds of incontinence, but they are generally most helpful for urge incontinence.

Anticholinergics. Anticholinergics work in the following ways:

Inhibit the involuntary contractions of the bladder
Increase capacity of the bladder
Delay the initial urge to void

A major 2003 analysis reported that these drugs produce small but significant improvements. However, the medications have not been rigorously compared with behavioral methods, such as bladder training and Kegel exercises, which are very effective for most cases of urge incontinence. Anticholinergics can have distressing side effects, notably dry mouth.

Anticholinergics include:

Propantheline (ProBanthine). This drug used to be the most commonly prescribed anticholinergic, but has been largely replaced by newer anticholinergics with fewer side effects.
Oxybutynin (Ditropan, Oxytrol)
Tolterodine (Detrol)
Hyoscyamine (Levbid, Cystospaz)

Extended-release versions of oxybutynin (Ditropan XL) and tolterodine (Detrol LA) are proving to be especially effective. They improve continence and have fewer adverse effects than short-acting forms. In a major 2003 comparison study of the extended release drugs, oxybutynin was slightly better than tolterodine, but dry mouth was reported more often. A skin patch form of oxybutynin (Oxytrol) is now available. It appears to work better and have fewer side effects, such as dry mouth and constipation, than the pill form.

Oxybutynin may cause more severe central nervous side effects than previously thought, especially for children and older adults. In 2007, the FDA reviewed 202 cases of oxybutynin-related central nervous system problems. Hallucinations were reported in 27% of pediatric cases and 25% of cases involving adults age 60 and older. Eleven percent of adults age 17 – 59 years experienced hallucinations. The FDA recommends that doctors monitor patients for these symptoms.

According to one study of tolterodine, the drug also improved quality of life. A 2006 study reported that tolterodine is helpful for men with overactive bladder and urge urinary incontinence. A 2006 study, published in the Journal of the American Medical Association, suggested that a combination of tolterodine and the alpha-blocker drug tamsulosin (Flomax) may work better than either drug alone for men with lower urinary tract symptoms, including overactive bladder.

Overactive Bladder Treatments for Children

Oxybutynin (Ditropan X) is approved for pediatric use in children ages 6 and older. The recommended dose is 5 mg once a day. A 2006 study suggested that children who have fewer episodes of daytime wetting may benefit most from this drug.
A 2004 analysis found that tolterodine is also effective and well tolerated in children with urinary symptoms due to overactive bladder.

Side effects of anticholinergic drugs include:

Dry eyes (a particular problem for people who wear contact lenses; patients who wear contacts may wish to start with low doses of medication and gradually build up)
Dry mouth
Headache
Constipation
Rapid heart rate
Confusion, forgetfulness, and possible worsening of mental function, particularly in older people with dementia, such as those with Alzheimer's disease
Hallucinations, possibly, especially for children and older adults
Glaucoma, in rare cases

Antispasmodics. Antispasmodic drugs help relax the bladder muscle and are used for urge incontinence. Before bladder relaxants are prescribed, a thorough evaluation for obstructions in the ureter must be performed to avoid excessive urine retention.

Flavoxate (Urispas) and dicyclomine (Bentyl), the most common antispasmodics, have been used for years, although studies suggest that Urispas has very little benefit for the majority of patients with urge incontinence. The drugs also have anticholinergic properties. In May 2004, the FDA approved a new antispasmodic, trospium chloride (Sanctura), for the treatment of overactive bladder with symptoms or urge incontinence.

Possible side effects reported with use of antispasmodic drugs include:

Weakness
Dizziness
Drowsiness
Hallucinations
Insomnia
Dry mouth
Impotence
Restlessness

M3 selective receptor antagonists. In 2004, the FDA approved darifenacin (Enablex) for treatment of urge incontinence and overactive bladder. Some clinical trials suggested that darifenacin could help reduce weekly incontinence episodes by 83%. The drug’s most common side effects are dry mouth and constipation. For elderly patients, darifenacin may have less negative effects on memory than oxybutynin.

Capsaicin and Analogs. Studies have reported beneficial effects from instillation of capsaicin, a component of hot red chili peppers, into the bladder of people with hyperactive and hypersensitive bladders. Temporary adverse effects, however, can be distressing. A capsaicin analog called resiniferatoxin may be more effective than capsaicin and have fewer side effects.

Alpha-Blockers. Alpha-blockers are drugs that relax smooth muscles and improve urine flow. They are useful for men with benign prostatic hyperplasia who also have urge incontinence. They include terazosin (Hytrin), doxazosin (Cardura), tamsulosin (Flomax), and alfuzosin (Xatral). Tamsulosin may be particularly beneficial. A 2006 study published in the Journal of the American Medical Association reported that the combination of tamsulosin and tolterodine works better than either drug alone for men with moderate-to-severe lower urinary tract symptoms, including overactive bladder. Men in the study were age 40 years and older and had symptoms related to overactive bladder and benign prostatic hyperplasia.

Alpha-Adrenergic Agonists. Alpha-adrenergic agonists are used to strengthen the smooth muscle that opens and closes the internal sphincter. They include ephedrine and pseudoephedrine, which are common ingredients in numerous over-the-counter decongestants and appetite suppressants.

Such drugs may be helpful for patients with mild stress incontinence not caused by nerve damage, although evidence on their benefits is weak. They also can have significant side effects, particularly ephedrine. In fact, products containing a similar drug, phenylpropanolamine (PPA), have been taken off the market because of reports of a higher risk for stroke in some women who took it.

Side effects may include agitation, insomnia, and anxiety. They may have adverse effects on the heart in people with existing heart problems. People with glaucoma, diabetes, hyperthyroidism, heart disease, or high blood pressure should avoid alpha-adrenergic agonists.

Nitrovasolidators. Deficiencies in nitric oxide, a gas that keeps blood vessels open, have been associated with many disorders, including incontinence. Drugs that release nitric oxide, such as nitroflurbiprofen, are being investigated for urinary incontinence.

Evidence indicates that both urge and stress incontinence are affected, in part, by central nervous system processes, particularly signal transmission. Investigators are particularly interested in serotonin and noradrenaline, which are chemical messengers (called neurotransmitters) that affect pathways involved with urination. (These neurotransmitters are also important for many other emotional and physical functions.) Antidepressants targeting one or both of these neurotransmitters are sometimes used for urge incontinence and may also be helpful for some people with stress incontinence.

Tricyclic Antidepressants. Tricyclic antidepressants include imipramine (Janimine, Tofranil), doxepin (Sinequan), desipramine (Norpramin), and nortriptyline (Pamelor). They provide multiple benefits for both urge and stress incontinence. They act as anticholinergic drugs and relax the bladder. They also strengthen the internal sphincter. These drugs should be used carefully. They pose some risk for adverse effects on the heart and possibly the lungs, and they have other severe side effects in older adults. These antidepressants produce side effects similar to anticholinergic drugs, and may cause drowsiness. They may also backfire and actually cause overflow incontinence in some people.
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs). SNRIs are specially designed antidepressants that are similar to tricyclics but do not have the same side effects. The neurotransmitters serotonin and norepinephrine are thought to play key roles in the normal action of bladder muscles and nerves. Increased neurotransmitter activity stimulates the nerve that controls the urethral sphincter. The SNRI duloxetine (Cymbalta) is approved in Europe for treatment of stress urinary incontinence. (It is approved in the U.S. for other conditions, but not stress urinary incontinence.) In 2005, the manufacturer of duloxetine withdrew its drug application after a small number of women in duloxetine urinary incontinence trials tried to commit suicide. The FDA is investigating whether duloxetine can cause suicidal behavior.

Desmopressin. Studies have reported that desmopressin (DDAVP), a drug used for bedwetting in children, may be helpful in treating adults with urinary incontinence that occurs during sleep. The drug affects sodium levels, and there is a slight risk for water intoxication with this drug.

Botulinum (Botox). Botulinum, the deadly toxin that sometimes contaminates improperly cooked foods, is also a powerful muscle-relaxant. Tiny injected amounts of a purified form (Botox) can relax the muscles and may help control overactive bladder that causes urge incontinence. It may also help relieve urinary retention that might occur after incontinence surgeries.

Stem Cells. Researchers are investigating muscle stem cell injections as a treatment for stress incontinence. Several small studies have indicated promising results. In these experiments, a doctor took a biopsy of skeletal muscle tissue from a patient’s arm. Stem cells were cultured and isolated from the biopsy sample. The doctor then injected the muscle-derived stem cells into the area surrounding the patient’s urethra that is close to the damaged sphincter muscle. In research results presented at the 2007 American Urological Association annual meeting and the 2006 Radiological Association of North American Meeting, patients experienced sustained improvements in bladder control and quality of life.

Surgery

There are nearly 200 procedures for incontinence. Most are designed to restore the bladder neck and urethra to their anatomically correct positions in patients with stress incontinence.

The American Urological Association suggests that surgery should actually be considered as initial therapy for women with severe stress incontinence. It is an effective and safe alternative when conservative treatments fail. Many of the procedures are safe even for women up to 80 years old who do not have serious medical conditions. Potential complications of all procedures include obstruction of the outlet from the bladder, causing difficulty in urination and irritation.

Deciding which procedure to choose is difficult and often depends on the factors causing the incontinence and whether anatomical abnormalities are involved. It should be noted that although hysterectomy has been shown to improve incontinence, it must not be performed only as a cure for incontinence.

In general, patients should weigh all options carefully. They should discuss the situation with their doctor, and ask about their surgeon's experience. As a general rule, the more times a surgeon has successfully performed a procedure, the better.

Retropubic Colposuspension Surgery. Retropubic colposuspension using standard "open" surgery is an effective treatment for stress incontinence, especially over the long term. ("Open" surgery implies the use of a wide incision in order to "open" the area.) Long-term continence rates can range from 85 - 90%.

The goal of colposuspension is to correct the position of the bladder and urethra by sewing the bladder neck and urethra directly to the surrounding pelvic bone or nearby structures. There are many variants, but, in general, they are effective only for women with urethral hypermobility. Most procedures require a general or spinal anesthetic and a 2-day hospital stay.

Burch colposuspension (sometimes called colpocystourethropexy) is a standard approach. It requires a wide abdominal incision and is often performed during abdominal surgeries such as hysterectomy or hernia operations. It is also performed along with sacrocolpopexy, a surgical procedure used to repair pelvic organ prolapse. (Pelvic organ prolapse occurs when the uterus or bladder slips from the pelvic cavity into the vagina. It is often due to pelvic muscle weakness that develops after childbirth.) Prolapse can lead to stress incontinence. However, prolapse surgery itself sometimes causes incontinence. A 2006 study suggested that a Burch colposuspension performed at the same time as sacrolpopexy can help reduce postsurgical stress incontinence.

The surgeon secures the urethra and bladder neck with lateral (sideways) sutures that pass through thick bands of muscle tissue running along the pubic bones. Unlike an older suspension procedure, this procedure poses a much lower risk for obstruction of the urethra. It is more effective in premenopausal than postmenopausal women and may not be appropriate for all women.

A rigorous 2007 study published in the New England Journal of Medicine compared the effectiveness of the Burch colposuspension to the sling procedure, another type of surgical treatment for stress incontinence. The study found that the sling procedure had better results for achieving dryness. However, more women who had the sling procedure had post-operative urinary problems, especially urinary tract infections. Overall, women were satisfied with the outcomes of both procedures. Eighty-six percent of women who had a sling procedure and 78% of women who had a Burch colposuspension reported satisfaction with their treatment.

Marshall-Marchetti-Krantz (MMK). The MMK approach requires a wide abdominal incision. The surgeon then elevates the urethra and bladder neck using sutures. These structures are then secured and anchored in nearby cartilage. This approach is one of the most reliable, but is used less often because of the risk for scarring and because the incision limits the surgeon's ability to correct any potential hernias (cystoceles).

Laparoscopy. Other less invasive procedures use laparoscopy, which requires only one or two small incisions over the pubic bone. Evidence suggests that laparoscopy, performed by an experienced surgeon, works just as well as standard surgery. While laparoscopy has a higher complication rate, it also has a faster recovery time and less postoperative pain. Still, well-conducted long-term studies are needed for an accurate comparison with standard colposuspension.

Needle Suspension. Needle suspensions include a number of approaches, including the Pereyra, Stamey, Raz, and Gittes procedures. The basic approach places stitches on either side of the bladder and ties them to muscle tissue or the pubic bone. Some of these procedures use transvaginal suspension, which requires only a small abdominal incision or no incision at all. In this case, the surgeon works through the vagina and places sutures through the vaginal walls. Transvaginal suspension works only if the walls of the vagina are strong enough to withstand the procedure. Some studies report poor long-term results, particularly compared to colposuspension. In one study, only 35% of patients who had transvaginal suspension reported success after 6 years. In another study, the failure rate was 83% after 4 - 5 years. Additional research has indicated that 20% of women have worse sexual function after the procedure.

Postoperative Considerations for Most Procedures. Following most standard procedures, patients usually leave the hospital on the second or third day, but need a urinary catheter for about 10 days. Newer procedures may require shorter stays and less intensive postoperative care.

Complications after surgery include:

Some risk of damage to the surrounding nerves or vessel. This can result in internal sphincter deficiency. (In some cases it may already have been present before the operation.)
Difficulty in urinating from surgical overcorrection. (This may require additional surgery.)
Poor wound healing.
Adhesions (scar tissue) that obstruct the urethra. This complication is higher with older standard procedures.
Vaginal abnormalities (prolapsed vagina).

A sling procedure may be a good option for severe stress incontinence in women who have either intrinsic sphincter deficiency or urethral hypermobility. The method is even proving to help women with mild-to-moderate incontinence and young girls with severe incontinence. It may also be useful for managing female urge incontinence. Sling procedures are also available for men who experience incontinence after prostatectomy.

Until recently, there were few clinical trials that directly compared the sling procedure with Burch colposuspension. In 2007, the New England Journal of Medicine published the results of the largest and most rigorous clinical trial conducted on these two types of surgery. In this study of 655 women with stress incontinence, half of the women underwent the sling procedure and half had open surgery with the Burch colposuspension.

Two years after surgery, success rates were highest for women who had the sling procedure. Forty-seven percent of women who had the sling procedure reported no urinary incontinence (either stress or urge) compared to 38% of women who had the Burch procedure. For stress-only incontinence, 66% of women who had the sling procedure and 49% of women who had the Burch procedure were dry. Eighty-six percent of women who had the sling procedure and 78% of the Burch group reported satisfaction with their treatment.

However, women who had the sling procedure did experience more post-operative urinary problems. The most common complication was urinary tract infections, which affected 63% of women who had a sling procedure compared with 47% of women who had the Burch procedure. A small number of women who had a sling procedure also reported difficulty voiding and urge incontinence.

The Percutaneous Sling Procedure for Women. The procedure generally works as follows:

The surgeon makes an incision above the pubic bone and removes a layer of abdominal fasci (tissue that covers muscle fibers). This muscle strip is set aside and later serves as the sling. (The uses of fasci taken from a cadaver or synthetic slings are also being investigated. However, the natural muscle strip may last longer than some of the common synthetic materials.)
The surgeon makes an incision in the vaginal wall. The piece of muscle fiber or material is attached under the urethra and bladder neck, somewhat like a hammock, and secured to the abdominal wall and pelvic bone.
This sling then compresses the urethra back to its original position. The sling must be supportive without being too tense, which can cause urinary obstruction.

Complications can include infection, bleeding, and the formation of fistulas (holes that form and are usually infected).

Vaginal Sling and Tape Procedures for Women. Newer outpatient procedures do not use abdominal incisions. Instead, they are performed through a small incision in the vagina. Typically, two small tacks are placed in the pubic bone. A sling is inserted into the vagina and is attached to the tack.

The tension-free vaginal tape (TVT) procedure uses a special gauze tape covered by a polypropylene coating, which is attached on each side of the urethra. The patient remains conscious and is asked to cough during the procedure so that the surgeon can determine if the tape is secure. Small early studies showed that the procedure worked as well as colposuspension (the standard suspension procedure), with stress incontinence cure rates of 84 - 100%. According to a 2005 study, the benefits of TVT can last for up to 8 years for women with stress incontinence. However, women with mixed incontinence (a combination of stress and urge) did not fare as well. Women with mixed incontinence had a 60% cure rate during the first 4 years following surgery, but the cure rate declined to 30% within 4 - 8 years post-surgery.

Sling Procedures in Men. For some men who have prostatectomy-induced incontinence, sling procedures may be a good option. Researchers have reported an 80% success rate, the same as an artificial urinary sphincter, which is the standard surgical treatment for such patients. The sling procedure has been less effective in men who have had radiation therapy, although improved techniques are making this approach useful even for these patients. Minimally invasive procedures are also being tested.

Artificial Sphincter. In cases of sphincter incompetence, or complete lack of sphincter function, an artificial internal sphincter may be implanted. This procedure is useful for appropriate male and female candidates of any age, including children. It is particularly helpful for men after radical prostatectomy. Studies have found poor results for patients with incontinence due to radiation therapies, although a 2001 study of men with prostatectomy indicated that it was useful regardless of previous radiation therapy.

Click the icon to see an illustrated series detailing artificial sphincter surgery.

This device uses a balloon reservoir and a cuff around the urethra that is controlled with a pump. The patient opens the cuff manually by activating the pump. The urethra opens and the bladder empties. The cuff closes automatically several minutes later. The two major drawbacks of the internal sphincter implant are:

Malfunction. If the implant malfunctions, the surgery must be performed again.
Infection. Infection is more serious as it can cause erosion of the urethra or bladder neck underneath the implant. Such infections not only require removal of the device, but also may worsen the incontinence. Fortunately, techniques have improved so that infection is uncommon.

In a 2001 study, after an average of 7 years, 70% of female patients with stress incontinence had either the original implant or a replacement, and 82% had urination properly restored. (Only 37% still had the original implant, however.) Studies on men have reported similar findings, although newer devices that use narrow cuffs may significantly improve re-implantation rates. Nearly all patients still need to use pads for leakage.

Injections of materials, such as collagen, that provide bulk to help support the urethra are proving to be beneficial for the following patients:

Women (even the elderly) with severe stress incontinence who cannot or do not wish to have surgery that involves anesthesia.
Men who have slight incontinence caused by prostate surgery. Men who have bulking injections after TURP (transurethral resection of the prostate) have a continence rate that is equal to the rate in women. After radical prostatectomy (removal of the prostate gland in prostate cancer), collagen injections can achieve some level of continence in up to nearly half of men. (Collagen injections are not beneficial after radiation therapy for prostate cancer.)

The Procedure.

First, bladder instability or hyperactivity should be medically treated and managed to control muscle activity before having the procedure. Otherwise it is likely to fail.
The basic procedure involves injecting bulking material into the tissue surrounding the urethra.
The material used is usually animal or human collagen. (Collagen is the basic protein in bones, muscles, and all connective tissue.) Synthetic bulking materials, such as carbon-coated beads, are also being used.
The doctor passes the collagen-containing needle through a cystoscope, a tube that has been inserted into the urethra. The collagen can also be injected into the skin next to the sphincter.
The injected collagen tightens the seal of the sphincter by adding bulk to the surrounding tissue.
The procedure takes about 20 - 40 minutes, and most people can go home immediately afterward.
Two or three additional injections may be needed to achieve satisfactory results.

Postoperative Care. People may experience immediate improvement followed by a temporary relapse after a week or so. Patients must be taught to use a catheter tube for withdrawing urine for a few days following the procedure. In general, it takes about a month for the full benefits to be apparent.

Complications.

There is a risk for infection and urinary retention, although these conditions are temporary.
An increase in autoimmune disease has been reported in a small number of cases.
The procedure may not be appropriate for patients with certain cardiac conditions.

Duration of Effectiveness. Collagen is absorbed over time, so injections generally need to be repeated every 6 - 18 months. According to one study, however, after a year 44% of women who had the implants still experienced the same level of improvement. (Synthetic materials may last longer than collagen from other sources, but they pose a risk for rejection as well as migration to the lymph nodes and other parts of the body.)

Anterior vaginal repair procedures that correct a prolapsed (fallen) uterus or vagina can often correct incontinence in women who have these conditions. The anterior vaginal repair (also called a bladder tuck) requires an incision to be made through the vagina. This releases part of the anterior (front) vaginal wall, which is attached to the base of the bladder. The pubocervical fascia (the supportive tissue between the vagina and bladder) is folded and stitched to bring the bladder and urethra into proper position. Several variations on this procedure may be necessary, depending on the severity of the prolapse. It is not as effective as retropubic suspension procedures, however, and should not be used as the primary method for correcting incontinence.

An interesting investigative approach uses radiofrequency energy to shrink tissue that supports the bladder neck and reduces hypermobility. Early studies are promising. In one, for example, the cure rate was nearly 80% at the end of a year, and 83% of patients reported satisfaction with the procedure.

Other Procedures

The sacral nerves, located in the tail bone, appear to play an important role in regulating bladder control. A sacral nerve stimulation system (InterStim) is now available for patients with urge incontinence. The system sends electrical pulses to the sacral nerves to help retrain them. InterStim is reserved for the treatment of urinary retention and the symptoms of overactive bladder in patients who have failed or cannot tolerate less invasive treatments. The system works as follows:

A stopwatch-size device is implanted under the skin in the abdomen.
A wire connected to it runs to the sacral nerves in the lower back.
The device, a battery-operated generator, produces electrical pulses.
The pulses are sent to the sacral nerves and reduce the hyperactivity of the bladder.
The sensation of the electrical pulse is similar to a slight pulling sensation in the pelvic area. Sometimes it can cause a small jolt or shock if the patient changes posture quickly. It should not cause pain. (If it does, something is wrong with the device.)

Complications include infection, lower back pain, and pain at the implant site. The system, however, does not cause nerve damage and can be removed at any time.

Patients have reported improvement in the frequency and volume of urination, as well as the intensity of urgency and their quality of life. Studies report complete dryness in nearly half of patients, with about 75% of patients experiencing relief from heavy leaking.

Transcutaneous Neuromodulation. The use of electrodes on the surface of the skin, called transcutaneous neuromodulation, may prove to be beneficial and particularly attractive for children.

Percutaneous Stoller Afferent Nerve Stimulation. The percutaneous stoller afferent nerve system (PerQ SANS System) has also been approved for urge incontinence.

In this therapy, a very thin needle is inserted a short distance above the ankle bone.
The needle is applied to the tibial nerve in the ankle, which connects with the sacral nerve complex.
Low-frequency electrical stimulation is applied for 30 minutes once a week for about 3 months.
After that, depending on the patient's response, treatments are given every week to every other week.
Short-term results are promising, but more research is needed.

Catheters and Collection Devices

A catheter is a slim flexible tube inserted into the urethra. They are mainly used for cases of severe urge incontinence.

A catheter (a hollow tube) may be inserted into the urinary bladder when there is a urinary obstruction, following surgical procedures to the urethra, in unconscious patients (due to surgical anesthesia, coma, etc.), or for any other problem in which the bladder needs to be kept empty (decompressed) and urinary flow assured.

Temporary Catheterization. For people who are still active, catheterization is often very distressing. If possible, temporary, also called intermittent, catheterization is usually the best choice. Patients insert the catheter tube into their urethras, generally every 3 - 4 hours. This type of catheterization carries few risks and empties the bladder completely. Some patients report that they can maintain an active life with no significantly increased risk for infection with some simple precautions:

Sterilize catheters at home.
Use a Zip Lock plastic bag for carrying them when leaving home.
Use another plastic bag for antiseptic cleansing solution.
When using public bathrooms, wash before and after catheterization. Touch as few places in the bathroom as possible.

Permanent Catheterization. People who are mentally or physically incapable of self-catheterization may need permanent catheterization.

The permanent catheter is inserted by a doctor or nurse into the opening of the bladder and a cuff is inflated to hold the tube in place.
Urine drains to an external collection device, which is generally strapped to the leg and must be emptied periodically.

The procedure is not painful, but there is a substantial increased risk of infection. Many experts feel that the catheter is overused, especially in the elderly.

Condom Catheters. Condom catheters are much more satisfactory than standard catheters for many male patients, although there is more spillage.

The condom is worn all day.
At night it is removed and washed for reuse the next day.

Collection Devices Attached to the Leg. For chronic or severe incontinence, collective devices drain urine into a bag that is attached to the lower leg and emptied periodically. These are generally more successful for men. Urine can be funneled into the tube by a pouch surrounding the penis. The positioning of the collecting device is difficult for women, and more accidents occur. For both men and women, irritation of the area around the urethral opening is a problem, since urine is in contact with the area for long periods.

At Home Spa Treatment: Coffee Scrub

FitSugar — Fri, 11 May 2007 14:30:00 -0700

I like the idea of whipping up an at home spa treatment with ingredients found in my kitchen cupboard. Recently, I came across not one, but two coffee scrubs and I thought I should tell you about them.

The first one, from Spa Index is an exfoliation scrub. All you need is:

2 cups of coarsely ground coffee

1/2 cup raw sugar or sea salt

2-3 T massage oil, or olive

Here's what you do:
Mix all ingredients together. Apply in hot shower after your skin is evenly moistened and your pores are open. Using wide, circular motions, rub the coffee mixture onto your skin with strong, even pressure. Rinse off, pat skin dry, and apply a thin layer of your favorite body lotion.

The second coffee rub, from Care2 claims to be a cellulite buster. I have seen many spas offering coffee cellulite treatments, and I don't believe anything like scrubbing your bum with coffee will get rid of the dimples. Cellulite occurs in 50 - 90 % of women regardless of their age or clothing size. But this scrub is an interesting variation on the coffee theme so I am sharing it with you.

Want to see what you need for this one? Then read more

1/4 cup warm used, caffeinated coffee grounds

tablespoon of olive oil

newspaper

1 roll of plastic wrap

Here's what you do:
Mix coffee and olive oil. Place newspaper on your bathroom floor. Apply coffee mixture to the cellulite area with your hands or a loofah. Some will fall onto the floor, hence the newspaper, you just need a thin layer of the scrub on your skin.

Wrap the area with plastic wrap, and keep it covered for several minutes. This might be a good time to give yourself a pedicure.

When your toe nail polish is dry, or you're just plain bored of hanging out dressed in nothing but coffee and plastic wrap, unwrap yourself and brush off the excess coffee mixture. Shower with warm water.

It is suggested that for best results you should repeat this process twice a week.

So maybe coffee is a pick me up for the skin too.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Acne is an inflammatory skin condition characterized by clogged pores, blackheads, and pimples. The oil glands, or sebaceous glands, are connected to hair follicles and release a substance known as sebum that lubricates hair and skin. Usually, sebum travels up the hair follicle and out onto your skin. But when the sebaceous glands produce too much oil and combine with dead skin cells, the follicles become blocked and inflamed. The nose, forehead, cheeks, chin, back, and trunk are the areas acne most often affects. Between 17 - 45 million people have acne, making it the most common skin disease in the United States. While it tends to last longer in women, men are more likely to get acne and tend to have more severe cases. Acne is most common in adolescents, and it generally disappears by age 30. Although it is not a serious health threat, severe acne can be painful and may cause permanent scarring, which can be upsetting for people who suffer from the condition.

Signs and Symptoms

There are several types of acne lesions:

Closed comedone (whitehead) -- a clogged follicle. Whiteheads usually appear on the skin as small, round, white bumps.
Open comedone (blackhead) -- a plugged follicle that opens and turns dark at the surface of the skin. Blackheads do not indicate the presence of dirt.
Papules -- inflamed lesions that appear as small, pink bumps on the skin.
Pustules (pimples) -- inflamed pus-filled lesions that are red at the base.
Cysts and nodules -- large, inflamed, pus-filled lesions deep under the skin that can cause pain and scarring.

Lesions can cause scars ranging from small, depressed pits to large elevated blemishes, depending on the severity of the acne and the person's skin type.

What Causes It?

Acne is caused by the combination of too much sebum and a buildup of dead skin cells, but no one knows what trigger the overproduction of sebum. During adolescence, rising hormone levels are thought to be a factor. The increased sebum blocks hair follicles, and small bacteria-filled cysts called comedones form. If these comedones do not rupture, they develop into whiteheads or blackheads. When comedones rupture, the inflammation can spread into the surrounding area. Papules, pustules, cysts, and nodules are types of inflammatory lesions.

Risk Factors

The following may cause or worsen acne:

Family history of acne
Using oily cosmetic or hair products containing vegetable or animal fats
Hormonal changes common during adolescence, pregnancy, or menstruation (acne tends to flare up 2 - 7 days before menstruation begins)
Certain medications such as corticosteroids, androgens, oral contraceptives, lithium, halogens, isoniazid, phenytoin, phenobarbital, and high levels of iodine (such as from kelp)
Sweating and friction on your skin, caused by headbands, back packs, bicycle helmets, or tight collars
Squeezing and picking comedones

What to Expect at Your Provider's Office

Acne is rarely a serious health problem, and general practitioners and internists can treat most people with mild-to-moderate forms of acne. People with more severe cases are often referred to a dermatologist. Your doctor will take a complete medical history that includes questions about skin care, cosmetic use, and diet; factors that trigger flare-ups; medication use; and prior treatment. Your doctor will also examine your face, chest, back, and other areas for blemishes, lesions, and scars.

Treatment Options

Treatments for acne involves lessening sebum production, helping the skin shed dead cells so they don't build up, and preventing bacteria from accumulating. The following self-care techniques may be helpful:

Wash skin once or twice a day with a mild cleanser. Washing more frequently, scrubbing skin, or using facial masks can make acne worse.
Use oil-free skin care products and cosmetics. Look for products that say "water-based" or "non-comedogenic."
Try over-the-counter lotions containing benzoyl peroxide or salicylic acid.
People with mild cases of acne may improve symptoms with herbs, Ayurveda, or homeopathy. Expect to use medications or complementary and alternative remedies for at least 6 - 8 weeks before seeing a noticeable improvement in symptoms.

Drug Therapies

Topical

Your doctor may also prescribe topical medications to treat acne. The most commonly used include:

Retinoids (tretinoin or Retin-A, adapalene or Differin, and tazarotene or Tazorac) -- are medications derived from vitamin A that work by unclogging pores and reducing inflammation. Side effects may include redness, peeling, and photosensitivity (high risk of sunburn). Most retinoids are applied at night and should not be applied at the same time as benzoyl peroxide (with the exception of adapalene). Pregnant women should not use topical retinoids during pregnancy.
Antibiotics -- work by killing bacteria and reducing inflammation. Topical antibiotics such as clindamycin or erythromycin are available in prescription form and may be used to treat mild-to-moderate acne.
Benzoyl peroxide -- Benzoyl peroxide is also available in prescription form.

Your doctor may recommend a combination of topical medications, such as benzoyl peroxide and clindamycin.

Oral

Your doctor may prescribe oral (taken by mouth) antibiotics either alone or in addition to topical medications for moderate-to-severe acne. For those with severe, inflammatory acne that does not improve with other medications, an oral retinoid called isotretinoin may be prescribed.

Antibiotics -- work by killing bacteria and reducing inflammation. Commonly prescribed oral antibiotics include doxycycline, minocycline, and tetracycline. Antibiotics taken by mouth should not be used during pregnancy or by children under 9.
Isotretinoin (Accutane) -- doctors aren't sure exactly how isotretinoin works, although it may reduce the production of sebum. It is usually prescribed for people with severe, inflammatory acne that does not improve with other medications. Isotretinoin is taken twice a day for 20 weeks. It causes severe birth defects and must not be used by pregnant women or those who may become pregnant. In fact, in the U.S. women who take isotretinoin are required to undergo regular pregnancy tests and take some form of prescription birth control.

Some women may be prescribed birth control pills that seem to reduce acne.

Surgery and Other Procedures

Surgery or other procedures can help improve the appearance of skin scarred by acne. Chemical peeling (where a chemical solution is applied to the skin that causes it to blister and eventually peel off) can reduce minor scars, while dermabrasion (a procedure that uses a rapidly rotating brush to remove the top layers of skin) can help more severe scarring. Laser resurfacing uses pulses of light to remove the top layer of skin and reduce scarring.

Complementary and Alternative Therapies

Nutrition

Although some people with acne report that certain drinks and foods (particularly nuts) make their symptoms worse, there is no scientific evidence that any food (even chocolate) affects acne. It is possible that food allergies may play a role in adult acne, and people may want to avoid foods that appear to aggravate their symptoms. Some doctors may suggest a low glycemic diet, which helps keep blood sugar stable and under control.

Zinc (30 mg two times per day for a month, then 30 mg per day) -- Several studies indicate that the mineral zinc may reduce the effects of acne. However, high doses of zinc can cause anemia, vomiting, and immune system suppression. It also interacts with tetracycline, which is often prescribed for acne. For these reasons, talk to your doctor before taking zinc.
Niacinamide (as a 4% topical gel) -- One study found that applying a 4% niacinamide gel to the skin two times per day for two months significantly improved acne symptoms. However, the study lacked a placebo, so it is hard to tell exactly how effective niacinamide might be.
L-carnitine -- Researchers in Greece showed that, among a large group of people, mild side effects from isotretinoin (dry skin, chapped lips, dry eyes, and nosebleeds caused by dry nose) improved when taking L-carnitine compared to those who took a placebo.
Vitamin A -- has many of the same properties as the retinoid drugs, but often with fewer side effects. Few studies have been done on vitamin A and acne, however. Too much vitamin A can be toxic, so talk to your doctor to determine the right dose for you, and only take higher doses of vitamin A under a doctor's supervision. Do not take extra vitamin A if you are pregnant or have liver disease.

Herbs

Tea tree oil (Melaleuca alternafolia, 5% gel) -- Applied topically, tea tree oil may help reduce bacteria on the skin, lessening inflammation and improving symptoms. One study compared the effectiveness of tea tree oil gel with benzoyl peroxide lotion in 119 people with mild-to-moderate acne. People in both groups improved, and the people using tea tree oil reported less side effects (including stinging, itching, burning, and dryness) than those using benzoyl peroxide.

Guggul (Commiphora mukul, dose equivalent to 25 mg guggulsterones or about 500 mg of guggul two times per day) -- In one study, taking guggul orally had the same effect as taking tetracycline. Guggul should not be taken by pregnant or nursing women. Guggul may have estrogen-like effects, and should not be taken by anyone with a history or family history of hormone-related cancers, including prostate cancer and breast or ovarian cancer. In addition, the herb may interact with anticoagulants (blood-thinning medications), tamoxifen, and birth control pills containing estrogen, as well as herbs that have estrogen-like effects (such as black cohosh, licorice, soy, and others). People who take these herbs or drugs should not take guggul.

Ayurvedic medicine -- Ayurvedic medicine may help improve symptoms, although further studies are needed. In one study, a combination of ginger (zingiber officinale), Holarrhena antidysenterica, and Embelia ribes reduced the number of inflammatory and non-inflammatory lesions. In another study, combined oral and topical use of Aloe barbadensis, Azardirachta indica, turmeric (Curcuma longa), Hemidesmus indicus, Terminalia chebula, Terminalia arjuna, and ashwagandha (Withania somnifera ) also reduced the number of lesions.

Homeopathy

There have been few studies examining the effectiveness of specific homeopathic remedies. Professional homeopaths, however, may recommend one or more of the following treatments for acne based on their knowledge and clinical experience. Before prescribing a remedy, homeopaths take into account a person's constitutional type. In homeopathic terms, a person's constitution is his or her physical, emotional, and intellectual makeup. An experienced homeopath assesses all of these factors when determining the most appropriate remedy for a particular individual.

Belladonna -- for people who experience flushes of heat to the face or who have inflamed pustular acne that improves with cold applications
Calendula -- for skin conditions involving pustules or blisters
Hepar sulphur -- for painful, pus-filled acne
Kali bromatum -- for deep acne, especially on the forehead, in persons who are chilled and nervous
Silicea -- for pustules or pit-forming acne

Other Considerations

Pregnancy

Pregnant women should avoid all retinoids (those either taken by mouth or applied to the skin), isotretinoin, and the antibiotics tetracycline, minocycline, and doxycycline because they can be harmful to the fetus. The antibiotic erythromycin (in both forms applied to the skin and taken by mouth) is safe to use during pregnancy.

Prognosis and Complications

Acne is not a serious health threat, but severe acne can be painful, emotionally upsetting, and may cause permanent scarring. Squeezing lesions can rupture comedones and cause inflammation. Infants with acne have an increased risk of developing acne in adolescence. Symptoms generally diminish after adolescence and disappear by age 30. However, the incidence of adult acne, especially in women, seems to be increasing and is not unusual in women in their 30s and 40s.

Exfoliating Dry Skin: It's All About the Sugar

FitSugar — Fri, 19 Jan 2007 03:30:00 -0800

Skin is the largest organ in your body, so you want to take care of it. Especially in the winter.

Scrub away dry dead skin while cleansing at the same time using sugar body polish. It's gentler on your skin than salt scrubs.

One of my faves is from Lunaroma. They make a Lavender and Geranium Sugar Body Polish that smells relaxing and fresh. They also have other scents like Cranberry Rose, Chocolate, and Ginger Snap.

After scrubbing in the shower, you can step out and seal in the moisture with silk - Body Silk that is. It's a cross between a lotion and an oil, and leaves your skin lusciously nourished.

They're all made with pure and natural ingredients in small batches by hand. Lunaroma offers all-natural alternatives to the leading chemical based body care products. So once you go natural, you'll never go back.

Mold: WTF?

FitSugar — Tue, 05 Dec 2006 03:30:00 -0800

In most cases mold is just a nuisance. While most molds prefer warmer temperatures, they can grow in the colder range. Molds also tolerate salt and sugar better than most other food invaders, which is why you may find mold in refrigerated jams and jellies and on cured, salty meats - ham, bacon and salami.

Guidelines for mold:

If ANY food is covered with mold, throw it away.
Cheeses: For hard cheeses, cut off at least an inch around and below the mold spot. Make sure to re-wrap it with fresh plastic. It's probably not worth saving individual cheese slices, soft cheese, cottage cheese, cream, sour cream or yogurt. Keep in mind that some cheeses are made with mold, but you can easily notice mold that shouldn't be there.
Hard Salamis & Country Hams: Cut a small spot of mold off hard salamis and ham using the hard cheese rule. If the salami or ham is covered with brown or black mold, toss it.

Want more tips on dealing with food mold? Then read more

Bacon, Hotdogs, Sliced Lunch Meats, Meat Pies or Opened Canned Ham:Throw out any with signs of mold.
Smoked Turkey: Cut small mold spots off the surface using the hard cheese rule.
Chicken: Throw out moldy cooked chicken.
Jams, Jellies and Syrups: Discard any showing any mold growth because the mold toxins (if present) can spread through this soft material quite rapidly.
Fruits and Vegetables: Cut out small mold spots from the surface of firm fruits and vegetables but discard soft vegetables showing mold.
Potatoes: Cut away tissue that is blackened or discolored. It's preferable (and easier) to do this before cooking.
Breads, Cakes, Buns, Pastries, Corn-on-the-cob, Nuts, Flour, Whole Grains, Rice, Dried Peas and Beans and Peanut Butter: Discard any visibly moldy items.

Also be sure to watch for any food you've had that is organic or made without preservatives, they are more prone to mold growth.

Fit's Tip: When cutting the mold spots off, be sure to not touch your knife to the mold. Also, mold spores from affected food can build up in your refrigerator, shortening the life of other foods. Clean the inside of the refrigerator every few months with baking soda dissolved in water. Scrub visible mold on rubber casings with bleach diluted in water. A musty smell on rags and sponges means they're spreading mold. Discard items you can't clean or launder.
