Moe's Southwest Grill Breakdown

FitSugar — Fri, 20 Jun 2008 05:30:00 -0700

When I'm on the road and in need of quick meal, I sometimes stop at Moe's Southwest Grill. It's like a Mexican version of Subway - you pick a type of burrito, taco, fajita, salad, or quesadilla, and then you choose exactly what goes in it (and you can watch them make it too). They use fresh veggies, but they don't use lard. Plus the meat is grilled right there. The food tastes great and seems healthy, but after looking at the caloric content of The Homewrecker and the Triple Lindy, I am happy that I split a burrito with my hubby.

To see the breakdown read more.

Nope, that last one is not a mistake. Talk about an unhealthy salad. Well, as disappointing as this info was, it's a great reality check. Just because something seems to be made with pretty basic ingredients, unless you make it yourself, you have no idea how much salt and fat it actually contains. I'll still frequent Moe's in a pinch, but definitely won't make a habit of it.

Every time you walk into Moe's, without a doubt, you are always greeted by the entire staff with a happy "Welcome to Moe's."

I went in there the other day because I was on the road and needed to eat. I thought I'd order a cheese quesadilla, because it'd be the safest item on the menu.

But Moe's isn't like other fast food joints - really it isn't. When you order, you get to watch the people make your food, so there's no "special" ingredients being added. They make all their own salsa and guacamole from scratch from actual vegetables.

Their beans are homemade everyday - using veggie broth- not lard. In fact, right smack dab on their menu it states "we don't use animal fat or lard." All their meat is cooked on one grill, and the veggies and tofu (yup, they have tofu) are cooked on a separate grill.

Fit's Tips: If you're counting calories or watching your weight, it's easy to figure out exactly what you're eating. Right on Moe's website, you can choose anything on the menu, including any toppings you want added or removed, and it configures the nutritional info for you. Just click on Nutrition at the bottom.

Kidney stones

HEALTH GUIDE REFERENCE FROM A.D.A.M

Highlights

New Research:

Patients who have the most common type of gastric bypass surgery, the Roux-en-Y, are at increased risk for kidney stones, beginning 6 months after surgery, according to a study published in 2006.

Causes of Kidney Stones:

Calcium stones form when there is an imbalance in the urine substances that promote and block the formation of stones. Often, the cause of this imbalance is unknown.
Having acidic urine or too much uric acid in the body leads to the formation of uric acid stones.
Struvite stones are almost always caused by urinary tract infections due to bacteria that produce certain enzymes.
Other stones, including cystine and xanthine stones, are usually due to genetic abnormalities.

Treatments:

In about 85% of patients, the kidney stones are small enough that they pass through normal urination, usually within 2 - 3 days.
Certain medications can prevent recurrence of stones in people who are at high risk.
Extracorporeal shock wave lithotripsy (ESWL) is a technique that uses sound waves (ultrasound) to break up simple stones in the kidney or upper urinary tract. The shock waves are delivered from outside the body.
Surgery may be necessary if the stone or stones are too big to pass, and cannot be broken down through ESWL.
A change of diet and increased drinking of fluids, especially water, will help prevent a recurrence.

Introduction

Kidney stones are hard, solid rocks that form in the urinary tract. In many cases, the stones are very small and can pass out of the body without any problems. However, if a stone (even a small one) blocks the flow of urine, excruciating pain may result, and prompt medical treatment may be needed.

The process of urination begins in the kidneys. The kidneys filter out fluids and waste from the body, producing urine. The two kidneys are located deep behind the abdominal organs, below the ribs and toward the middle of the back.

Each kidney contains over a million nephrons. These are the tiny filtration units of the kidney.
Each nephron is composed of a tiny group of blood vessels (a glomerulus) enclosed in a funnel-like structure called Bowman's capsule.
Each glomerulus filters waste products, water, and salts out of the liquid part of the blood (plasma) that has entered the kidney.
About 1% of the plasma is converted into urine. The rest returns into the blood to prevent dehydration. Urine is primarily made of acids, urea, and creatinine (nitrogen compounds).
Urine passes from Bowman's capsule into tiny tubules, which lead to large collecting tubes in the center of the kidney. As the urine passes through this network, it becomes more concentrated.
Urine then flows from the kidney through thin tubes called ureters into the bladder.
The bladder's stretchy walls expand to store the incoming urine until it leaves the body through a tube called the urethra.

The kidneys are responsible for removing wastes from the body, regulating electrolyte balance and blood pressure, and stimulating red blood cell production.

Occasionally, various salts build up on the inside surfaces of the kidney and form crystals. Eventually these crystals become large enough to form stones in the kidney, a condition called nephrolithiasis. Kidney stones (renal calculi) may also form in the ureter or the bladder. Combinations of minerals and other chemicals, some derived from a person's diet, make up the salts in these stones.

Calcium Stones. About 70 - 90% of all kidney stones are made of calcium, usually combined with oxalate, or oxalic acid. A number of common vegetables, fruits, and grains contain oxalate.

About 6% of calcium stones are made of calcium phosphate (called brushite).

Uric Acid Stones. Uric acid is responsible for close to 10% of kidney stones. It is the breakdown product of purines, nitrogen compounds found in our bodies and in certain foods. The breakdown of purines to uric acid occurs in the liver, and from there uric acid enters the bloodstream, most of it passing into the kidneys. From the kidneys, uric acid leaves the body in the urine. Often, uric acid stones occur with calcium stones.

Struvite Stones. Struvite stones are made of magnesium ammonium phosphate. They are almost always associated with certain urinary tract infections. Worldwide, they make up to 30% of all kidney stones. In the United States, however, less than 15% of all stones are struvite. Most struvite stones occur in women. The rate of these stones may be declining in America, perhaps because of better control of urinary tract infections.

Cystine Stones. A build-up of the amino acid cystine, a building block of protein, causes 1% of kidney stones in adults and up to 8% of stones in children. The tendency to form these stones is inherited. Cystine stones are marked by rapid growth and recurrence, which, if not treated promptly, can eventually lead to kidney failure.

Xanthine Stones. Other kidney stones are composed of xanthine, a nitrogen compound. These stones are extremely uncommon and usually occur as a result of a rare genetic disorder.

Causes

The key process in the development of kidney stones is supersaturation.

The urine carries salts, including calcium oxalate, uric acid, cystine, or xanthine.
These salts can become extremely concentrated if there is not enough urine, or if unusually high amounts of crystal-forming salts are present.
When salt concentration levels reach the point at which they no longer dissolve, these salts form crystals.

Different factors may be involved in either reducing urine amount, or increasing the levels of the salts.

Deficiencies in Protective Factors. Normally, urine contains substances that may protect against stone formation, including:

Magnesium
Citrate
Pyrophosphate
Enzymes

These substances:

Allow salt in the urine to be at higher-than-normal concentrations without forming crystals
Prevent crystal formation
Coat the crystals and prevent them from sticking to the surface of kidney tubes

Not having enough of these protective substances can cause stones.

Changes in the Acidity of the Urine. Changes in the acid balance of the urine can affect stone formation.

Uric acid and cystine stones mainly form in acidic urine.
Calcium phosphate and struvite stones increase in alkaline urine.

Factors that Bind Crystals to the Kidney Tubules. Researchers are studying the cells lining the kidney tubules in order to understand how and why early crystals bind to the tubes long enough to form stones. Under investigation are elevated levels of substances that either cause crystals to stick to the tubes or deficiencies in those that prevent them from sticking.

In general, calcium stones form when there is an imbalance in the urine substances that promote and block the formation of stones. Often, the cause of calcium stones is not known, and the condition is then called idiopathic nephrolithiasis. Research suggests that nearly all stones result from problems in the breakdown and absorption of calcium and oxalate. Genetic factors may play a role in about half of these cases. A number of medical conditions and drugs can also affect digestion and intestinal absorption.

Excess Calcium in the Urine (Hypercalciuria). Hypercalciuria (too much calcium in the urine) is responsible for as much as 70% of calcium-containing stones. A number of conditions may produce hypercalciuria. Many are due to genetic factors, but most cases are idiopathic (due to unknown causes).

The following can lead to hypercalciuria and calcium stones:

Too much calcium absorption in the intestines: In most of these conditions, genetic factors lead to increased calcium absorption in the intestine. Researchers are investigating a possible defective gene that regulates calcitriol, a form of vitamin D, which, in excess levels, may increase intestinal absorption of calcium.
Excessive chloride: Chloride has a negative charge, and calcium has a positive one, so they balance each other in the body. Excess chloride may lead to excess calcium. A gene known as CLCN5, which regulates chloride in the urine, is defective in many patients with calcium stones.
Renal calcium leak: In this condition, the filtering processes in the kidney fail, causing an increase of calcium in the urine.
Excessive sodium: High urinary levels of sodium result in increased levels of calcium. Certain defects in the kidney tubules transport system, which cause imbalances in sodium and phosphate, can lead to high calcium levels in the urine. A diet high in salt can also produce this effect.

Excess Oxalate in the Urine (Hyperoxaluria). Oxalate is the most common stone-forming compound. Excessive oxalate in the urine (hyperoxaluria) is responsible for up to 60% of calcium stones and is a more common cause of stones than too much calcium in the urine.

Hyperoxaluria can be either primary or secondary.

Primary hyperoxaluria is an inherited disorder in which too much oxalate in the urine is the main problem.
Secondary hyperoxaluria results from specific conditions that cause high levels of urinary oxalate.

Secondary hyperoxaluria is usually caused by too much dietary oxalates (found in a number of common vegetables, fruits, and grains) or by problems in the body's breakdown of oxalates. Such defects may be due to various factors:

Severe vitamin B6 deficiencies (usually due to genetic disorders)
Deficiencies in Oxalobacter formigene, an intestinal bacteria that breaks down oxalate
Short bowel syndrome, a condition that makes the intestines unable to properly absorb fat and nutrients; calcium may bind to unabsorbed fat instead of oxalates, which causes a buildup of oxalate
Androgens (male hormones)

Female hormones (estrogens) actually lower the risk of hyperoxaluria. Estrogen may help prevent the formation of calcium oxalate stones by keeping urine alkaline, and raising protective citrate levels.

A study published in 2006 found that patients who undergo the most common gastric type of bypass surgery, the Roux-en-Y, were at increased risk for calcium oxalate kidney stones, beginning 6 months after surgery. The study found that patients who underwent the procedure developed hyperoxaluria, and the condition was common 12 months after surgery. The authors also noted an increased number of kidney stone incidents in this patient group.

Excessive Calcium in the Bloodstream (Hypercalcemia). Hypercalcemia generally occurs when bones break down and release too much calcium into the bloodstream. This is a process called resorption. It can occur from a number of different diseases and events:

Hyperparathyroidism: Overactive parathyroid glands cause about 5% of calcium stones. People with this disorder have at least a 20% chance of developing kidney stones. Women are more likely to have this disorder than men.
Immobilization: Lack of movement can lead to kidney stones.
Renal tubular acidosis: This disorder causes acidic and alkaline imbalance. Renal tubular acidosis not only increases calcium levels in the bloodstream but also reduces protective citrate levels.

Hyperuricosuria is a condition of high levels of uric acid in urine. It occurs in between 15 - 20% of people (mostly men) with calcium oxalate stones. Urate, the salt formed from uric acid, creates the center of a crystal (nidus), around which calcium oxalate crystals form and grow. Such stones tend to be severe and recurrent. They appear to be strongly related to a high intake of protein. (Hyperuricosuria also plays a major role in some uric acid stones.)

Low Urine Levels of Citrate (Hypocitraturia). Citrate is the main substance in the body that is responsible for removing excess calcium. It also blocks the process that turns calcium crystals into stones. Low levels of citrate in the urine (hypocitraturia) is a significant risk factor for calcium stones. In addition, hypocitraturia also increases the risk for uric acid stones. This condition most likely contributes to about a third of all kidney stones.

Many conditions can reduce citrate levels. Some causes include:

Renal tubular acidosis
Potassium or magnesium deficiency
Urinary tract infection
Kidney failure
Chronic diarrhea

Often, however, the cause of hypocitraturia-related stones is unknown.

Low Levels of Other Stone-Blocking Compounds. Several other compounds in the urine, including magnesium and pyrophosphate, also prevent the formation of calcium stones. If any of these compounds are lacking, stones may develop.

Nanobacteria Infection. Nanobacteria are tiny infectious organisms that can pass from the blood into urine. They coat themselves with mineral deposits that resemble the composition of kidney stones. Cells infected with these bacteria develop mineral deposits on the inside and outside. Researchers believe that nanobacteria may form the cores of the kidney stones in many people.

Human body tissues, certain foods, and certain alcoholic drinks contain substances called purines. Purine-containing foods include dried beans, peas, and liver. When the body breaks down purines, it produces uric acid. The presence of a certain level of uric acid in the body is normal.

The following conditions are usually seen in patients with uric acid stones:

Too much acid in the urine for a long period (the most important cause of uric acid stones)
Lower than normal amounts of urine produced.
Hyperuricosuria, a metabolic disorder that leads to high levels of uric acid in the urine

Note: Hyperuricosuria can also trigger calcium stones. Therefore, a combination of calcium and uric acid stones may be present in patients with hyperuricosuria.

A number of conditions and other factors may contribute to, or cause, uric acid stones:

Gout: Uric acid and other kidney stones develop in up to 25% of patients with primary gout, a painful form of arthritis that occurs when uric acid in the blood forms crystals in one or more joints.
Diabetes: New research has shown that people with type 2 diabetes have highly acidic urine that can lead to kidney stones, particularly uric acid stones. The findings were published in the May 2006 Journal of the American Society of Nephrology.
Insulin resistance: People with insulin resistance are at an increased risk for uric acid stones. The reason is unknown but may be related to the transport of certain salts through the kidneys. This transport changes in patients with insulin resistance.
Kidney abnormalities: Kidney problems that reduce the production of ammonia, particularly in people with diabetes or insulin resistance, may lead to uric acid stones.
Genetic factors: Genetic factors can increase a person's risk for uric acid stones.
Hypocitraturia: Hypocitraturia is a low amount of citrate in the urine.
Diet: Eating too much animal protein increases the risk of forming uric acid stones.

Other risk factors include:

Certain medications (chemotherapy drugs, diuretics, and salicylates)
Binge drinking
Not eating for long periods of time (fasting)
Lead poisoning
Blood cancers (leukemia, multiple myeloma, and lymphomas)
Some rare types of anemia (low levels of red blood cells in the blood)
Chronic diarrhea

Struvite stones are almost always caused by urinary tract infections due to bacteria that produce certain enzymes. These enzymes raise the concentration of ammonia in the urine. Ammonia makes up the crystals that form struvite stones. The stone-promoting bacteria are usually Proteus, but may also include Pseudomonas, Klebsiella, Providencia, Serratia, and staphylococci. Women are twice as likely to have struvite stones as men.

Other stones, including cystine and xanthine stones, are usually due to genetic abnormalities.

Causes of Cystine Stones. Cystine stones develop from genetic defects that cause abnormal transport of amino acids in the kidney and gastrointestinal system leading to a build-up of cystine, one of these amino acids. Researchers have identified two genes responsible for this condition: SLC3A1 and CLC7A9.

Causes of Xanthine Stones. In some cases, xanthine stones may develop in patients being treated with allopurinol for gout.

Risk Factors

Kidney stones are one of the most common disorders of the urinary tract. They are an ancient health problem. Evidence of kidney stones has been found in an Egyptian mummy estimated to be more than 7,000 years old.

An estimated 1.3 million Americans seek medical help for kidney stones each year. At this time, studies suggest kidney stones affect over 5% of Americans and that the rate has increased since the 1970s, perhaps because of increases in animal and dietary protein intake.

Men. The risk of kidney stones increases in a man's 40s and continues to rise until age 70. Caucasian men are at higher risk than other groups.

Women. The risk of kidney stones peaks in a woman's 50s. In younger women, stones are more likely to develop during the late stages of pregnancy. Pregnant women tend to have a higher calcium intake, but their kidneys do no handle the calcium as well as they did prior to pregnancy. Kidney stones are still a rare occurrence during pregnancy, however, affecting only 1 in 1,500 pregnancies.

Risk Factors in Children. Stones in the urinary tract in children are usually due to genetic factors. Most of the time, the cause is too much calcium in the urine (hypercalciuria). Deformities in the urinary tract pose a significant risk for kidney stones in children. Children with low birth weight who need to be fed intravenously are also at risk for stones.

Obesity and weight gain are both associated with an increased risk of kidney stones.

Men who weigh more than 220 lbs are 44% more likely to develop kidney stones than men who weigh less than 150 lbs.
Women who are obese are 90% more likely to develop kidney stones than women with a lower body mass index (BMI).

Higher BMIs and larger waist circumferences are both risk factors for kidney stones. Researchers think that there may be a link between fat tissue, insulin resistance, and urine composition. People with larger body sizes may excrete more calcium and uric acid, which increase the risk of kidney stone formation.

A family history of kidney stones increases one's risk for the condition. Researchers are looking into markers or other factors that might predict kidney stones in relatives, although none has yet been clearly identified. One report found that among the siblings of patients with calcium stones, sisters with higher urinary calcium levels and more acidic urine were more likely to develop stones. Brothers with high urinary calcium, low urinary potassium, and older age were more likely to have the problem. A family history of gout may also make a person vulnerable to stones.

According to a 2003 study of American ethnic groups, Caucasians have the highest incidence of kidney stones (5.9%) followed by Mexican Americans (2.6%). African-Americans have the lowest risk (1.7%).

Dietary factors, minerals in local water, or both may contribute to geographic differences that have been observed in the occurrence of kidney stones. Studies have reported the highest occurrence of kidney stones in the southern region of the United States and the lowest in the west. One study suggested that the higher risk may be due to a higher rate of high blood pressure in the southern states and certain dietary habits, particularly lower intake of magnesium and low use of calcium supplements.

Specific Foods. In general, certain foods increase the risk for stones only in people who have genetic or medical vulnerability. People whose diets are high in animal protein and low in fiber and fluids may be at higher risk for stones. A number of foods contain oxalic acid, but there is no proof that such foods make any major contribution to calcium oxalate stones in people without other risk factors. However, several studies have shown that increasing dietary calcium and restricting salt, animal protein, and foods rich in oxalate can help prevent calcium oxalate stones from returning.

Stress. One study reported that people who had a major, stressful life experience were more likely to develop stones than those who had not. Some experts speculate that this increased risk may be due to a hormone called vasopressin, which is released in response to stress. Vasopressin also increases the concentration of urine.

Sleep Position. Sleeping in the same position consistently may influence risk. A 2001 study reported that in people who had a history of kidney stones, recurrences tended to occur on the same side that people slept on. An earlier study suggested that people who had kidney stones were more apt to sleep on their stomachs. Movement during sleep did not appear to affect the risk.

Being Bedridden. Any medical or physical condition that keeps a person in bed or immobile increases blood levels of calcium from bone breakdown, thereby posing a risk for stone formation.

Gout. Patients with gout are at a high risk of uric acid stones. These patients have very acidic urine, and a 2002 study suggested that the two disorders may have a common source.

High Blood Pressure. Persons with high blood pressure are up to three times more likely to develop kidney stones. It is not entirely clear whether having high blood pressure increases the risk for a stone, whether stones lead to high blood pressure, or if there is an action linking both.

Inflammatory Bowel Disease: Crohn's disease and ulcerative colitis cause problems in absorption of substances in the intestines. These problems significantly increase the risk for kidney stones, particularly in men.

Urinary Tract Infections (UTIs): Urinary tract infections are almost always the cause of struvite stones.

Hyperparathyroidism: The parathyroid glands regulate calcium levels in the body through the parathyroid hormone. In hyperparathyroidism, one or more of these glands makes too much parathyroid hormone. Some people with hyperparathyroidism develop kidney stones. Surgery to remove the hyperactive parathyroid gland in such patients reduces the risk for stone formation, but the risk still remains high for some time after surgery.

Other Medical Conditions. Kidney disease, chronic diarrhea, certain cancers (such as leukemia and lymphoma), and sarcoidosis put people at higher risk for stones.

AIDS medications. Over 10% of persons with AIDS who take the medicine indinavir develop stones. The risk is even higher in patients with AIDS who also have hepatitis B, hepatitis C, or hemophilia, as well as those who are very thin or who take the antibiotic combination TMP-SMX. In one study of persons with AIDS who took a combination of indinavir, zidovudine, and lamivudine, 36% developed kidney stones.

Other Drugs. Kidney stones are a rare side effect of thyroid hormones and loop diuretics (drugs that increase urination). In fact, diuretics are also used to prevent calcium stones. Certain cancer chemotherapies can also cause kidney stones. Long-term use of medications, such as antacids, which change the acidic content of urine, may increase the risk for kidney stones.

Symptoms

In many cases, kidney stones do not produce symptoms. However, if a stone becomes stuck in the ureter (the thin tube between the bladder and the kidney), symptoms can be very severe. Often, they vary depending on the stone's location and its progress.

Kidney stone attacks tend to be most common late at night or in the early morning, possibly because of minimal urine output or constriction of the ureters during the early morning hours. Kidney stone attacks are least common during the late afternoon

Pain usually begins abruptly on one side and then usually continues as intense, constant pain. (In some cases it persists for a few minutes, disappears, and then returns after about 10 minutes.)
The patient cannot become comfortable and usually stands, sits, paces, or reclines in a vain search for a position that will bring relief.
If the stone is in the kidney or upper urinary tract, the pain usually starts in one flank area (to the side of the back near the waist). It typically moves to the groin as the stone passes down.
If the stone is too large to pass easily, the pain follows the muscle contractions in the wall of the ureter as they try to squeeze the stone along into the bladder.
Nausea and vomiting may occur.
Blood in the urine may be present.
As the stone passes down the ureter closer to the bladder, a person may feel the need to urinate more often or a burning sensation during urination.
If fever and chills accompany any of these symptoms, an infection may be present.

The size of the stone does not necessarily predict the severity of the pain; a very tiny crystal with sharp edges can cause intense pain while a larger round stone may not be as distressing. Struvite stones can often occur without symptoms.

Diagnosis

The doctor will perform a physical exam. This includes pressing against abdominal areas for tender locations that might indicate the presence of the stone.

The patient's age is a significant factor. Kidney stones that occur in children and young patients are more apt to result from inherited problems that cause cystine, xanthine, or, in some cases, calcium oxalate stones. In adult patients, calcium stones are most common.

A medical history may help predict which crystal has formed the stone. The doctor will need to know the following:

Any previous kidney stone attacks
Histories of cancer, sarcoidosis, or small bowel disease
Any medications being taken, including non-prescription substances, particularly high doses of vitamins D or C and calcium-containing antacids

Many conditions can cause symptoms similar to kidney stones. Usually the diagnosis is easily made because of the specific nature of the symptoms, but it is not always clear. Urinary tract infections can cause similar, but usually less intense, pain. In fact, infection may be present with a kidney stone. Other causes of pain that may mimic kidney stones include:

Gallstones
Diverticulitis (infection or irritation of abnormal pockets in the intestines)
Intestinal blockage
Blood clots
Irritable bowel syndrome
Appendicitis
Stomach ulcers
Hiatal hernia (when the upper part of the stomach bulges into the chest, through an opening in the diaphragm)
Pancreatitis (inflammation of the pancreas)
Hepatitis
Pelvic inflammatory disease
Inflammatory bowel disease (Crohn's and colitis)
Heart attack

Various imaging techniques are helpful in determining the presence of kidney stones. The best approach uses spiral (or helical) computed tomography scans. If it is not available, the patient will need ultrasound or standard x-rays. If no stones show up, but the patient has severe pain that suggests the presence of kidney stones, the next step is an intravenous pyelogram.

X-Rays. A standard x-ray of the kidneys, ureters, and bladder may be a good first step for identifying many stones, since many are visible on x-rays. Calcium stones can be identified on x-rays by their white color. Cystine crystals can also show up on x-rays.

Spiral (or Helical) Computed Tomography. A type of computed tomography (CT) scan, called a spiral or helical CT scan, is currently the best method for diagnosing stones in either the kidneys or the ureters. This test is fast, does not require instruments or foreign chemicals to enter the body, and provides detailed accurate images of even very small stones. If stones are not present, a spiral CT scan can often identify other causes of pain in the kidney area. It is better than x-rays, ultrasound, and intravenous pyelogram -- the previous standard test for detecting kidney stones. Experts hope spiral CT will eventually be able to identify the chemicals present in a stone.

Ultrasound. Ultrasound can detect clear uric acid stones and obstruction in the urinary tract. It is not useful for finding very small stones, but some research indicates that it may be a useful first diagnostic step in the emergency room to help predict the likelihood of a stone, including suspected stones in children.

Intravenous Pyelogram. With intravenous pyelogram (IVP), the doctor injects a special dye into the patient. A technician will then take x-rays as the dye enters the kidneys and travels down the urinary tract. IVP is invasive but, until recently, was the most cost-effective method for detecting stones. Where it is available, spiral CT is now preferred, since it gives a faster diagnosis, is more accurate, is safer, and is similar in cost.

In any case, IVP should not be used on patients with kidney failure. There is also a risk for an allergic reaction to standard dyes, although newer less allergenic ones are becoming available.

In the procedure intravenous pyelogram (IVP), the patient is injected with dye. X-rays are taken as the dye travels through the urinary tract. This procedure is done to confirm the presence of kidney stones, although some stones may be too small to see.

Magnetic Resonance Imaging. Magnetic resonance imaging (MRI) techniques are showing promise for diagnosing urinary tract obstruction but do not yet accurately reveal small stones, or ones that do not cause a blockage. Because no radiation is involved with MRI, however, it may prove to be a good option for pregnant women.

Urine samples are required to evaluate features of the urine, including its acidity and the presence of:

Red or white blood cells
Infection
Crystals
High or low levels of chemicals that inhibit or promote stone formation

Clean-Catch Urine Sample for Culturing. After determining that a kidney stone is present, the health care provider usually gives the patient a collection kit, including filters, to try to catch the stone or gravel as it passes out. The urine may also be tested (cultured) for the presence of infection-causing organisms. A clean-catch urine sample is almost always required for culturing. To provide a clean catch, do the following:

First, wash your hands thoroughly, then wash the penis or vulva and surrounding area four times with downward strokes, using a new soapy sponge each time.
Begin urinating into the toilet and stop after a few drops.
Position the container to catch the middle portion of the urine stream. Ideally, this urine will contain only the bacteria and other evidence of the stone.
Urinate the remainder into the toilet.
Tighten the cap on the container securely, being careful not to touch the inside of the rim.

Twenty-Four Hour Urine Collection. A 24-hour urine collection may be needed to measure urine volume and levels of acidity, calcium, sodium, uric acid, oxalate, citrate, and creatinine.

You should not change any of your usual eating or drinking patterns when performing this test.
Discard the first urination on the day of the test.
Afterward all urine passed over the next 24 hours is collected, including the first urination on the morning of day two.
A second 24-hour urine collection may be needed to determine if treatment is working or if the first analysis was not conclusive and the doctor suspects a less common stone, such as a cystine or xanthine stone.

Click the icon to see an image of a uric acid urine test.

Urine tests that are used to determine the specific chemical and biological factors causing the stone should be performed about 6 weeks after the attack, since the attack itself may change the levels of such substances, including calcium, phosphate, and citrate. It should be noted that calcium levels in the urine may be abnormal even in many people without stones. In addition, high urinary concentrations of calcium may pose a greater or lesser risk depending on age. (In one 2001 study, middle-aged adults with high urinary calcium concentrations had a much greater risk than older adults with high levels.)

The kidney stones obtained from the urine sample are examined under a microscope. The crystal formations are often specific enough so that the doctor is able to identify the substance causing the stone.

Calcium oxalate crystals are eight-sided, while calcium phosphate crystals tend to have irregular shapes.
Uric acid stones are sometimes described as pear-shaped or diamond-shaped.
Some struvite stones have very specific shapes commonly described as "coffin lids." Struvite crystals may also occur in a formation known as a staghorn, which can be large and damaging to the kidney.

Testing whether urine is acidic or alkaline helps to identify the specific type of stone. The levels of acidity or alkalinity in any solution, including urine, are indicated by the pH scale:

A pH value of 7.0 is neutral.
A solution with a low pH (below 7.0) is acidic. (A low pH favors uric acid and cystine stones.)
A solution with a high pH is alkaline. (A high pH favors calcium phosphate and struvite stones.)

A dipstick test for blood in the urine (called hematuria) is typically performed when patients appear in the emergency room with flank pain (the primary symptom of kidney stones). About a third of kidney stone patients, however, do not show blood in the urine, so other tests may be needed.

Blood Tests for Stone Factors. Blood and urine tests help determine what substances form the crystals. This allows the doctor to determine the appropriate treatment and preventive measures.

Blood tests may help determine blood levels of urea nitrogen, creatinine, calcium, phosphate, and uric acid for patients with known or suspected calcium oxalate stones. Doctors will usually schedule these tests about 6 weeks after the attack, in order to measure these substances when the stone has been passed, and the patient has been stabilized. This is particularly true in patients with recurrent stones.

Parathyroid Tests. Tests to detect parathyroid hormone levels are given if the doctor suspects hyperparathyroidism, based on other signs and symptoms.

Tests for Infection. A test result that shows a high white blood cell count might indicate infection. Such results, however, could be misleading, since the number of white blood cells could also increase in response to the extreme physical stress of a kidney stone attack.

Tests for Metabolic Problems. About half of children with stones have an identifiable metabolic disorder, which increases their risk of stone recurrence five-fold. Experts argue whether tests for metabolic disorders are routinely needed once the stone composition has been determined. Studies suggest the following:

People with recurrent calcium stones have a wide range of irregular blood or urine test results, indicating a variety of possible metabolic disorders. For example, calcium stones in middle-aged women may be due to parathyroid abnormalities.
Calcium phosphate stones most likely result from renal tubular acidosis.
People with non-calcium stones generally have identifiable metabolic disorders.
Determining the stone composition may be sufficient for treatment, and may help avoid unnecessary metabolic tests.

Treatment

When tests show there is a kidney stone, the next step is to determine treatment. The patient should be admitted to the emergency room if they have severe vomiting, fever, or symptoms of infection.

Strong opioid painkillers, such as meperidine (Demerol), are often required for a severe kidney stone attack. However, doctors will usually not give such drugs until they confirm the presence of a kidney stone on an x-ray. In some cases, powerful nonsteroidal anti-inflammatory drugs (NSAIDs) may work just as well as opioids, and they have fewer side effects. However, they do take longer to work.

In about 85% of patients, the kidney stones are small enough that they pass through normal urination, usually within 2 to 3 days. In some cases, a stone may take weeks to months to pass, although pain usually goes away before that.

The patient should drink plenty of water (two to three quarts a day) to help move the stone along, and take painkillers as needed. The doctor usually provides a collection kit with a filter and asks the patient to save any passed stones for testing.

If the stone has not passed in 2 - 3 days, the patient will need additional treatments. In some severe cases, hospitalization may be necessary.

Specific procedures vary depending on the size of the stone or complexity of the situation. Noninvasive procedures are proving to be very beneficial in eliminating stones, and have largely replaced invasive surgeries.

For small stones that are lodged in the lower part of the ureter, ureteroscopy or shock wave lithotripsy are the procedures of choice.
For larger stones, ureteroscopy, percutaneous nephrolithotomy, and shock wave lithotripsy are all potentially useful. The choice of any of these procedures depends on a number of factors, including location of the stone and the presence of any problems that caused the stone in the first place.
In some complicated cases, standard open surgical procedures (called nephrolithotomy) may be required.

See "Other Treatments" section for more information on kidney stone surgery.


Stone Type	Diet and Lifestyle	Medications	Procedures
Calcium Oxalate	Plenty of fluids. (Choose water, lemon juice. Avoid grapefruit, apple, and cranberry juice.) Limit the amount of protein and salt in the diet. Increase fiber. Limit the amount of fats in the diet, particularly in people who have short bowel syndrome. Balance normal calcium intake with potassium- and phosphate-rich foods. Limit the amount of calcium in the diet (only in people who have genetic abnormalities that cause high intestinal absorption of calcium). Limit the amount of foods high in oxalates (only in patients with rare intestinal conditions that cause hyperoxaluria).	Diuretics ("water pills"), Citrate salts, phosphates, cholestyramine.	Lithotripsy, uteroscopy, percutaneous nephrolithotomy, open surgery.
Uric Acid	Plenty of fluids. (Choose water, blackcurrant juice. Avoid cranberry juice.) Increase calcium intake (be sure well-balanced with potassium and phosphates). Reduce protein and other foods with high-purine content.	Potassium citrate, sodium bicarbonate, allopurinol.	Lithotripsy, uteroscopy, percutaneous nephrolithotomy, open surgery.
Struvite stones	Plenty of fluids (water, cranberry juice). Reduce proteins.	Antibiotics to eliminate any infection. Acetohydroxamic acid (AHA) may be helpful in combination with antibiotics. In some cases, organic acids given through urinary tract.	May respond poorly to most lithotripsy procedures and require open surgery. Newer procedures may be helpful.
Cystine stones	Very high fluid intake (four quarts a day). Limit the amount of protein in the diet.	Alkalizing agents (such as bicarbonate). Sometimes d-penicillamine, tiopronine, or captopril useful for lowering cystine levels.	May respond poorly to most lithotripsy procedures and require open surgery. Newer procedures may be helpful.

Medications

Diuretics. Diuretics are medicines commonly used to treat high blood pressure and other disorders. They remove fluid and sodium from the body. Low doses of a class of diuretics known as thiazides are sometimes used to reduce the amount of calcium released by the kidneys into the urine. Thiazides include:

Hydrochlorothiazide (Esidrix, HydroDiuril)
Chlorothiazide (Diuril)
Trichlormethiazide (Metahydrin, Naqua)
Chlorthalidone (Hygroton)

However, thiazides also cause potassium loss, which reduces citrate levels and can increase the risk for stones. Patients taking thiazide pills should also take potassium citrate, to prevent citrate loss. Amiloride (Midamor) is a potassium-sparing diuretic, which may be used if a thiazide does not work.

Citrates. Citrate salts are often given to people with calcium oxalate or uric acid stones:

Potassium magnesium citrate is available over the counter. It is proving to be very beneficial in preventing kidney stones. In one study, potassium magnesium citrate reduced the risk for kidney stone recurrence by 85%.
Potassium citrate (K-Lyte, Polycitra-K, Urocit-K) is given as the only treatment to people with normal urine calcium levels. Between 70 - 75% of patients with recurrent stones have ongoing remission (no stone recurrence) with potassium citrate treatment. However, some people cannot tolerate potassium citrate because of side effects (stomach problems).
Magnesium citrate (Citroma, Citro-Nesia) may help people who develop calcium stones from impaired intestinal absorption due to short bowel disease.

None of these products should be used by people with struvite stones, urinary tract infections, bleeding disorders, or kidney damage. Patients who take citrate supplements containing potassium should not take any other medications that either contain this mineral or prevent its loss (such as so-called potassium-sparing diuretics). People with peptic ulcers should avoid citrate supplements, or discuss using non-tablet forms with their doctor.

Phosphates. Phosphates help reduce the breakdown of bone that releases calcium into the bloodstream. They are also involved in the kidney's reabsorption of calcium from the urine.

Phosphate compounds:

Neutral (nonacidic) sodium or potassium phosphate (K-Phos, Neutral, Neutra-Phos) is usually taken four times a day after meals to prevent kidney stones unless otherwise directed by the doctor. Diarrhea is a possible side effect.
Cellulose phosphate (Calcibind) is recommended only for severe hypercalciuria that is associated with recurrent calcium stones and is caused by excessive absorption of calcium from the intestines. However, this drug may increase oxalate levels and decrease magnesium levels, which can lead to different stones. Taking magnesium supplements and reducing dietary oxalates, calcium, and ascorbic acid may help offset these risks. Cellulose phosphate may also cause bloating.

Avoid acidic forms of phosphate, since they increase the risks for both hypocitraturia and hypercalciuria.

Cholestyramine (Questran, Questran Light) is a drug used to reduce cholesterol levels. However, it also binds with oxalate in the intestine, so it is also used to reduce high oxalate levels in urine (hyperoxaluria). The drug usually comes in a powder that is dissolved in liquid.

Bloating and constipation are common side effects of this drug. Cholestyramine also interferes with other medications, including digoxin (Lanoxin) and warfarin, and may contribute to calcium loss and osteoporosis. In order to prevent such interactions, take other drugs 1 hour before, or 4 - 6 hours after, taking cholestyramine.

Long-term use of cholestyramine may cause deficiencies of vitamins A, D, E, and K. Vitamin supplements may be necessary.

Sodium Bicarbonate. Patients whose persistently acidic urine causes uric acid stones may take sodium bicarbonate to reduce urine acidity. Patients taking sodium bicarbonate must test their urine regularly with pH paper, which turns different colors depending on whether the urine is acidic or alkaline. Too much sodium bicarbonate can cause the urine to become too alkaline. This increases the risk for calcium phosphate stones. Patients who need to reduce the amount of sodium they take in (as a result of other medical conditions) should not use sodium bicarbonate.

Potassium Citrate. Potassium citrate, which restores citrate to the urine, is useful for patients with high levels of uric acid in the urine.

Allopurinol. Allopurinol (Lupurin, Zyloprim) is very effective in reducing high levels of uric acid, and may be helpful for patients with uric acid stones. Allopurinol will not prevent calcium stones from forming. There is also a slight risk for the formation of xanthine stones with this drug. Side effects include diarrhea, headache, and fever. More severe complications include blood disorders that may produce fatigue, bleeding, or bruising. The drug may also increase the risk for cataracts.

About 2% of patients experience an allergic reaction to allopurinol that causes a rash. In rare cases, the rash can become severe and widespread enough to be life threatening. Allergic individuals who have experienced only a mild rash to sodium bicarbonate may be able to build up their tolerance for allopurinol by undergoing a desensitization process. In this process, patients start with small doses of allopurinol and gradually increase them, if no reaction develops.

Allopurinol reduces uric acid levels rapidly, so it may trigger an attack of gout in vulnerable people. To prevent this problem, patients taking allopurinol should also take a nonsteroidal anti-inflammatory drug (NSAID) for 2 or 3 months. Aspirin should not be taken, since it increases uric acid levels. Patients should discuss the appropriate NSAID choice with their doctor.

Before patients can receive any medical treatment for struvite stones, they must have surgery to completely remove the stones.

Antibiotics for Eliminating Infection. Persons with struvite stones receive ongoing treatment with antibiotics to keep the urine free of the bacteria that cause urinary tract infections. Careful follow-up and urine testing is extremely important. A high-pH urine indicates low acidity and an increased risk of infection.

Acetohydroxamic Acid (AHA). Acetohydroxamic acid (AHA or Lithostat) is beneficial when used with long-term antibiotics. AHA blocks enzymes that bacteria release, and has been effective in preventing stones even when bacteria are present. Side effects, however, can be severe. The drug reduces iron levels in the body, so anemia is a common problem. Patients may need to take iron supplements. Other side effects include nausea, vomiting, depression, anxiety, rash, persistent headache, and, rarely, small blood clots in the legs.

Experts recommend this drug only for patients with healthy kidneys who have chronic diseases caused by specific struvite-causing organisms.

Patients taking this medicine should avoid alcohol. Pregnant women should not take acetohydroxamic acid.

Organic Acids. Medical treatments to dissolve stones may be useful in patients who do not respond to other medications, or in combination with surgeries. Acidic urine dissolves struvite stones, so the doctor may wash the urinary tract with a solution of organic acids (such as Renacidin). Candidates for such washes must have sterile urine (no bacteria or other organisms in the urine) and healthy kidney function. In surgical patients, the wash is performed 4 or 5 days after the operation. The wash starts with saline (salt solution) for 1 - 2 days and, if there are no problems, the organic acid solution follows for another 1 or 2 days, until all stones dissolve. Regular urine tests are necessary to ensure that the bacteria do not return.

Aluminum Hydroxide Gel. An aluminum hydroxide anti-acid gel may reduce phosphate levels that are important in struvite stone formation, but it has a long-term risk of causing aluminum toxicity. Long-term reduction of phosphorus can also increase the risk for calcium oxalate stones. Experts recommend limiting phosphorus through a low-protein diet, rather than through the use of this gel.

The first-line treatment for cystine stones is increasing the alkalization of urine so the stones can dissolve. If alkalization fails, drug treatments may include d-penicillamine, alpha-mercaptopropionylglycine (tiopronine), or captopril. These medications lower cystine concentration.

Patients with cystine stones must drink plenty of fluids, much more than patients with other stones. The patients should drink at least four quarts of water over a 24-hour period.

Other Treatments

Surgery is usually needed if the stone is too large to pass on its own, if there are signs that the stone is growing, or if the stone is blocking the urine flow and causing a urinary tract infection or kidney damage.

Until recently, the procedure to remove a stone was a very painful, major surgery, requiring 4-6 weeks of recovery. Today, treatments for stones are much less invasive. Major surgery is performed in less than 2% of patients.

Stone removal procedures:

Extracorporeal shock wave lithotripsy (ESWL) is used for small stones (less than one centimeter, or slightly less than half an inch) that occur in the upper part of the ureter and do not pass on their own. One study indicated lithotripsy might even be safe and effective for patients whose stones are associated with malformed kidneys, although such patients are at higher risk for stone recurrence and should be carefully monitored.
Percutaneous nephrolithotomy (PNL). PNL can be used for very large stones in the upper urinary tract, when ESWL fails, for kidney transplant patients, or when the kidneys or surrounding areas are malformed. PNL is the preferred procedure for drug-resistant cystine stones, which are usually also resistant to shock wave therapy.
Ureteroscopy. For stones in the lower tract, ureteroscopy is generally the best procedure, although lithotripsy is also usually feasible and patients ordinarily prefer it.
Standard open surgery (nephrolithotomy) may be required if any of these procedures fail or are not appropriate, or in special cases, such as when the patient is very obese.

Most procedures are more effective for calcium and uric acid stones and less effective for struvite and cystine stones, although new techniques may be improving their effects on all stones.

Extracorporeal shock wave lithotripsy (ESWL) is a technique that uses sound waves (ultrasound) to break up simple stones in the kidney or upper urinary tract. ("Extracorporeal" means "outside the body," and "lithotripsy" means stone-breaking.) ESWL is not used for cystine stones. The procedure generally does not work for stones larger than three centimeters in diameter (which is slightly over an inch). There are several variations of ESWL. The following is a typical procedure:

Most ESWL procedures use some anesthesia, although they are often done on an outpatient basis.
The patient is positioned in a water bath. (In some procedures the patient lies on a soft cushion.)
The procedure uses ultrasound to generate shock waves that travel through the skin and body tissues until they hit the dense stones. (The doctor pinpoints the stone during treatment by using x-rays or ultrasound.)
The shock waves crush the stones into tiny sand-like pieces that usually pass easily through the urinary tract.
The shattered stone fragments may cause discomfort as they pass through the urinary tract. In such cases, the doctor may insert a small tube called a stent through the bladder into the ureter to help the fragments pass. This practice, however, has not proved to speed up passage of the stones in most cases and is not used routinely.

Extracorporeal shock wave lithotripsy (ESWL) is a procedure used to shatter simple stones in the kidney or upper urinary tract. Ultrasonic waves are passed through the body until they strike the dense stones. Pulses of sonic waves pulverize the stones, which are then more easily passed through the ureter and out of the body in the urine.

Success rates of ESWL range from 50 - 90%, depending on the location of the stone and the surgeon's technique and level of experience. Recovery time is short, and most people can resume normal activities in a few days.

Complications. Complications may include the following:

The most common complication is blood in the urine, which lasts for a few days after treatment. To reduce the chances of bleeding, doctors usually tell patients to avoid taking aspirin and other NSAIDs, which can promote bleeding, for 7 - 10 days before the treatment.
Bruising and minor discomfort due to the shock waves are common in the back or abdomen.
Sometimes the stone does not completely break up with one treatment, and additional treatments may be required. Inability to pass stone fragments may also be a particular problem in patients who have cysts or other kidney problems.
Higher risk for diabetes later. A 2006 study published in the journal Urology found that 17% of patients who received shock-wave lithotripsy developed diabetes later in life. The diabetes risk was related to the number and intensity of shocks.
Higher risk for hypertension (high blood pressure). The same study that linked ESWL to diabetes also showed that people who received shock-wave lithotripsy treatment were 47% more likely to develop high blood pressure than those who had their stones treated without surgery.

ESWL appears to be safe for children, although a 2001 study reported temporary damage in the kidney tubules after treatment. It is unclear if this complication has any long-term consequences. Experts recommend using the least amount of shocks and impact possible in young people. If more than one treatment is needed, there should be a waiting period of at least 15 days between treatments.

Percutaneous nephrolithotomy may be used when ESWL is not available or effective (such as if the stone is very large, in an inaccessible location, or is a cystine stone). It is also preferred over ESWL for stones that have remained in the ureter for more than 4 weeks.

It is more effective than ESWL for patients with severe obesity, and appears to be safe for the very elderly and the very young. Success rates are nearly 98% for kidney stones and 88% for ureteral stones. They may vary by the technique used and the specific patients. For example, success rates are slightly lower in children, although the procedure can be done safely in young patients. Long-term effects are unknown.

A typical procedure is as follows:

The surgeon makes a tiny incision in the back and creates a tunnel directly into the kidney.
The surgeon then inserts an instrument called a nephroscope through the tunnel.
The stone is located and removed. If it is large, it is destroyed using ultrasound, lasers, or other devices. The surgeon then removes the fragments. An advantage of percutaneous nephrolithotomy over ESWL is that the surgeon is able to remove the stone fragments directly, instead of relying on their natural passage from the kidney.
Generally, patients stay in the hospital for 5 or 6 days and may need a small device called a nephrostomy tube left in the kidney during the healing process.

Devices Used to Destroy Stones. For large stones, some type of energy-delivering device may be needed to break the stone into small pieces. They are referred to as intracorporeal lithotripsy devices (meaning stone breakers within the body). The device may be one of the following:

Ultrasound is currently the preferred method. It results in a stone-free rate of 94%. A rigid nephroscope delivers the ultrasound waves.
Pneumatic (compressed air) lithotripsy uses a probe that comes in direct contract with a stone. Compressed air causes a piston to collide rapidly with the probe, and the result is a "jackhammer" action against the stone, causing the stone to break up. This method, however, can send stone fragments into other parts of the urinary tract.
A more recent device uses a combination pneumatic probe and ultrasound, with stone-free rates of 80 - 89%. It may prove to be superior to ultrasound alone and be effective against stones of all types.
The holmium laser literally melts the stones and destroys up to 100% of stones of any composition. It uses a flexible nephroscope and has an excellent safety record. It should be used sparingly, however, with particular caution against large uric acid stones until more is understood about its effect. Another device, the erbium: YAG laser, although showing promise in lithotripsy, is not currently practical.

Complications. Complication rates are about 3%. Major complications occur in about 1% of cases. These complications may include scarring of the tissue, but studies indicate that it does not impair kidney function, even if the patient requires repeat surgery. There is also a risk for blood loss during and after the procedure, which, in some cases, can be significant.

Because the procedure requires large volumes of fluid, fluid overload is a potential problem, particularly in children or patients with heart disease.

In some cases, infection may result. Other complications may include a collapsed lung and injuries to areas outside the kidney (but within the operative area), such as the abdomen or chest.

Ureteroscopy may be used for stones in the middle and lower ureter. With the arrival of smaller instruments, this procedure can be done successfully in children as well. The procedure involves the following:

The patient receives a general anesthetic, though no incision is required for the procedure.
The surgeon passes a small fiberoptic instrument called a ureteroscope through the urethra and bladder into the ureter.
The surgeon locates the stone or stones.
The surgeon can remove smaller stones by grasping them with small forceps. A laser or pneumatic device breaks up large stones.
The surgeon may decide to leave a small tube, or stent, in the ureter for a few days after treatment, to help the lining of the ureter heal.

Complication rates range from 10 - 20%, with major problems occurring in up to 6% of patients. In some cases, large stones are not broken up into small enough pieces. This can result in blockage of the urinary tract and possible kidney damage.

Imaging tests, such as ultrasound or spiral CT, are useful within 3 months to check for residual stones, and a second procedure may be required. The risk of complications is highest when the procedure is performed by less experienced surgeons, or if stones are found in the kidney. The risk for perforation of the ureter increases the longer the procedure takes.

Open surgery involves incisions through the patient's flank and into the kidney. The surgeon will cool the kidneys using ice. X-rays during the procedure help locate the stone. At the beginning of the surgery, the surgeon will isolate the arteries supplying the kidneys, ensuring they are not harmed during the surgery. The surgeon will then locate and remove the stone. The surgeon will also correct any blockage in the affected area. The surgery, called nephrolithotomy, is very invasive and is restricted to the following:

Patients with very large or complex stones that cannot be removed using less invasive measures
Very obese patients

Some centers report success with extracorporeal shock wave lithotripsy, however, in patients who would normally be nephrolithotomy candidates. Therefore, even these patients should discuss other options with their surgeon.

The procedure is not appropriate for patients with:

Bleeding or clotting disorders
Untreated widespread infection
Severe and chronic kidney insufficiency (unless removing the stone will improve kidney function)

Complications

Between 70 - 90% of crystals remain tiny enough so that they can travel through the urinary tract and leave the body in the urine without being noticed. When they do cause symptoms, however, kidney stones have been described as one of the most painful disorders to afflict humans. The pain they cause is sometimes called renal colic. ("Renal" means "kidney.")

Obstruction and Infection. Although kidney stones often lead to obstruction (blockage) of the urinary tract, the blockage is usually temporary and causes no lasting damage. In some cases, however, particularly if the obstruction progresses with no symptoms, infection may occur, which can be serious and need immediate attention.

Kidney Failure. It is very rare for kidney stones to cause kidney failure, although some people have risk factors that make them more vulnerable to this serious complication. Risk factors include the following:

Very frequent recurrences (such as in people with cystine stones or other inherited forms of kidney stone disorders)
Accompanying episodes of urinary tract infections with obstruction, a particular risk with struvite stones
A history of multiple urologic procedures for kidney stones
Greater size of the kidney stone gravel

Without preventive treatment, calcium stones recur in 10% of patients within a year of the first attack, and in half of patients within 5 - 7 years. Individual risk for recurrence, however, varies depending on the stone and the underlying condition. For example, a 15-year-old with inherited cystine stones has a very high risk for recurrence, while a middle-aged man with a first calcium oxalate stone has a good chance of never passing another.

Prevention

All individuals who have experienced kidney stones should take some specific preventive measures to prevent recurrence. The following are some general observations:

The most important dietary recommendations for reducing the risk for calcium stones are increasing fluid intake, restricting sodium, and reducing protein intake.
A lower risk for calcium stones is also associated with higher potassium intake.
A high calcium diet does not appear to increase the risk for kidney stones as long as it also contains plenty of fluids and dietary potassium and phosphate. (Increasing calcium alone may pose a modest risk for stones.)
Patients should try to correct any dietary habits that cause acidic or alkaline imbalances in the urine, which promote stone formation.

Because different kidney stone types may require specific dietary changes, patients should work with their doctors to develop an individualized plan. It is important to note that nutritional considerations are very important in preventing recurrence, and patients should be vigilant in complying with the proper diet.

Good voiding habits, particularly frequent urination, are important. Therefore, of all the preventive recommendations, drinking enough fluids is the most important guideline for people with any type of kidney stones.

In general, patients with calcium or uric acid stones should drink at least 10 full glasses of fluid each day (at least half should be water). This includes one with each meal and drinking fluids at night, even if it means getting up from sleep. Fluid intake should produce at least two and a half quarts of urine each day.
To prevent cystine stones, patients should drink even more water -- over a gallon, or 16 8-ounce cups, every day. Patients should drink this amount at regular intervals throughout the night and day.

In all cases, patients need more fluid after exertion and during times of stress. If they drink enough, the urine should be pale and almost watery, not dark and yellow.

Water. Although water is best, it may vary depending on its source. Variations in water itself may have different impacts. One study reported that drinking hard tap water increased urinary calcium concentration by 50% compared to soft bottled water. On the other hand, mineral water containing both calcium and magnesium may reduce several risk factors for both calcium and uric acid stone formation.

Juices and Specific Effects. Other beverages have various positive or negative effects, depending on the type of stone:

Lemon Juice: Drinking one-half cup of pure lemon juice (enough to make eight glasses of lemonade) every day raises citrate levels in the urine, which might protect against calcium stones. (While orange juice also increases citrate levels, it does not lower calcium and it raises oxalate levels. Therefore, it is not recommended.)
Cranberry and Apple Juice: Apple and cranberry juice contain oxalates, and both have been associated with a higher risk for calcium oxalate stones. Cranberry juice has properties that may increase the risk for both calcium oxalate and uric acid stones. On the other hand, cranberry juice helps prevent urinary tract infections and so may be helpful for reducing the risk for struvite and brushite stones. (These stones are far less common, however.)
Black Currant Juice: In one study, black currant juice reduced urine acidity and was associated with protection against uric acid stones.
Grapefruit Juice: A number of studies have found a risk for stones from drinking grapefruit juice. In one study, just one 8-ounce cup of grapefruit juice per day increased the risk for forming stones by 44%.

Other Beverages and Their Effects on Stone Formation.

Soft Drinks. Patients with stones should avoid cola drinks, since they can severely reduce citrate levels in the urine. Many soft drinks contain phosphoric acid, which increases the risk for stones. Some research shows that drinking one quart (less than three 12-ounce cans) of soda per week may increase a person's risk of developing stones by 15%.
Alcohol. Wine may be protective against kidney stones. A study conducted in Finland, suggests that the risk of developing stones also decreases with beer consumption. However, it is important to remember that beer is high in oxalates. Beer and other alcoholic beverages also contain purines, which may increase the specific risk for the less common uric acid stones in susceptible people. Binge drinking, in any case, increases uric acid and the risk for stones.
Coffee and Tea. Some research reported a lower risk for stones in people who drink tea and both regular and decaffeinated coffee.

A long-term 2002 study followed men with calcium oxalate stones and high levels of urinary calcium. The study found that a low-sodium, low-protein diet, containing normal levels of calcium, dramatically reduced the recurrence of stones compared to a diet that was simply low in calcium.

Salt Restriction. Because salt intake increases the amount of calcium in urine, patients with calcium stones should limit their sodium intake. Sodium may also increase levels of urate, the crystalline substance that can trigger formation of recurrent calcium oxalate stones. Although the relative contribution of limiting sodium intake has not been confirmed, some researchers believe that restricting sodium along with increasing fluid intake is the most important dietary measure for preventing stones.

Protein Restriction. Protein increases uric acid, calcium, and oxalate levels in the urine, and reduces citrate levels. Diets high in protein, particularly meat protein, have been consistently connected with kidney stones. (Meat protein has a higher sulfur content and produces more acid than vegetable protein.) A 2002 study of those following a high-protein, low-carbohydrate diet (such as the Atkins diet, for example), found dramatically increased levels of urinary uric acid and calcium after just several weeks. These effects put patients at higher risk for not just kidney stones, but possibly osteoporosis as well. According to Swiss studies, about a third of people at risk for calcium stones may have a sensitivity to meat proteins that causes mild hyperoxaluria.

Whether restricting meat protein alone has any protective value without restricting sodium as well is unknown. Most studies to date have found no difference in stone development between people with low and normal meat protein diets over four years. A 2000 study reported that only dramatic reductions in meat protein had any preventive effect against stone recurrence.

Although the precise role of dietary protein in kidney stones needs further clarification, it is reasonable for everyone to consume meat protein in moderation. People with struvite stones, who need to reduce phosphates in their diets, should also cut down on proteins.

Calcium from Foods. Dietary calcium recommendations for kidney stone prevention need to be determined on an individual basis. A doctor will suggest calcium guidelines based on a patient's age, gender, body size, and type of stone. Most studies indicate that dietary calcium (found in milk, yogurt, and cheese) protects against many types of calcium oxalate stones. Large studies of both men and women found that those with the highest intake of calcium from foods had a much lower risk for stones than those who had little calcium in their diets. A diet containing a normal amount of calcium, but reduced amounts of animal protein and salt, may protect against stones better than a low-calcium regimen. However, calcium metabolism changes as people age. Some studies suggest that a high calcium intake protects against kidney stones in men younger than age 60, but not in older men.

Dietary calcium may actually bind the oxalate in foods, preventing it from being absorbed into the blood and excreted into the urine. In a normal healthy diet, dairy products supply almost 80% of the daily calcium requirement. For people who have calcium stones associated with resorption (the breakdown of bone that releases calcium into the bloodstream), limiting calcium intake could cause further bone loss.

Calcium Supplements. Evidence on calcium supplements is mixed, although in general many studies suggest that they reduce oxalate levels and so help prevent calcium oxalate stones. One study suggested that taking 500 mg of calcium supplements a day regularly may "reprogram" the intestines to absorb less calcium and may therefore be protective. Experts generally agree that calcium supplementation within dosage recommendations (about 1,200 mg per day) remains safe. In one study, however, women who took calcium supplements had a 20% higher risk for stones. Research indicates that dosages of calcium above 2,000 mg per day are clearly associated with the formation of stones. Some experts speculate that this higher risk may occur because supplements are often taken in the morning, either without food or with breakfast, which is typically low in oxalates. Taking supplements with later meals may not produce the same risk.

Calcium Restriction in Certain Cases. Some patients, such as those whose stones are caused by genetic defects in which the intestine absorbs too much calcium, may need to limit calcium intake. More studies are needed to define this group precisely.

Fiber may be beneficial for people with kidney stones. In addition, some fiber-rich foods may contain compounds that help protect against kidney stones. A wide variety of high-fiber plant foods contain a compound called phytate (also called inositol hexaphosphate, InsP6, or IP6), which appears to help prevent crystallization of calcium salts, both oxalate and phosphate. Phytate is found in legumes and wheat and rice bran. (Soybeans are also rich in phytate but they are also very high in oxalates, so the overall effects of soy on kidney stones are not clear.)

A high intake of purines can increase the amount of uric acid in the urine. Those at risk for uric acid stones should reduce their intake of foods and beverages that contain purines. These include beer and other alcoholic beverages, anchovies, sardines, yeast, organ meats (such as liver and kidneys), legumes (including dried beans, peas, and soybeans), mushrooms, spinach, asparagus, cauliflower, and poultry.

Most people with calcium oxalate stones should not avoid oxalate-rich foods unless the doctor specifically recommends a restrictive diet. Oxalate binds with calcium in the intestine, which may actually reduce calcium absorption. Some studies, in fact, indicate that eating foods containing oxalates and calcium together may reduce the risk of stones. Most of the foods that contain oxalates are very important for good health. Limiting oxalates may be particularly harmful in people with bowel disorders marked by malabsorption.

Foods high in oxalic acid include beets, soy, beet tops, black tea, chenopodium, chocolate, cocoa, dried figs, ground pepper, lamb, lime peel, nuts, parsley, poppy seeds, purslane, rhubarb, sorrel, spinach, and Swiss chard.
Foods containing moderate amounts of oxalates include beans (green and wax), blackberries, blueberries, carrots, celery, coffee (roasted), concord grapes, currants, dandelion greens, endive, gooseberries, lemon peel, okra, green onions, oranges, green peppers, black raspberries, strawberries, and sweet potatoes.

Certain fats may play a beneficial or harmful role in specific cases of kidney stones.

Restricted Fats in Patients with Stones Associated with Bowel Disease. Patients who have stones associated with short-bowel syndrome should eat foods with lower amounts of fats and oxalates. If patients with short-bowel syndrome eat too much fat, calcium may bind to unabsorbed fat instead of to oxalates. This increased oxalate levels, resulting in increased risk of stone formation.

Fish Oil. Omega-3 fatty acids, found in oily fish like mackerel, salmon, and albacore tuna, have many health benefits, but the most current evidence suggests they do not help prevent kidney stones. A 2005 study of over 200,000 adults found that increased omega-3 fatty acid intake did not reduce kidney stone risk.

Vitamin B6. Vitamin B6, or pyridoxine, is used to treat people with primary hyperoxaluria, a severe inherited disorder. Patients should not try to treat themselves with vitamin B6. Very high doses (500 to 2,000 mg daily over long periods) can cause nerve damage, with loss of balance and numbness in the feet and hands. Food sources of vitamin B6 include meats, oily fish, poultry, whole grains, dried fortified cereals, soybeans, avocados, baked potatoes with skins, watermelon, plantains, bananas, peanuts, and brewer's yeast.

Vitamin C. Ascorbic acid (vitamin C) may change in the body to tiny crystals, called oxalates. These crystals do not dissolve. People with hyperoxaluria (too much oxalate in the urine) should avoid vitamin C supplements. Even for men with normal oxalate levels, higher consumption of vitamin C (more than 1,000 mg a day) may increase kidney stone risk.

Magnesium and potassium may help reduce the risk for kidney stones in men.

Because of an association between stress and kidney stones, relaxation and stress management techniques may also be beneficial.

Dietary Considerations. People with kidney stones appear to be more sensitive to certain foods than people who do not form kidney stones. Therefore, vulnerable people should make specific changes in their diet. They should work with their doctors to develop a dietary plan that fits their individual situation. Drinking plenty of fluids is important for preventing recurrence of any kidney stone.

Indications for Drug Treatments. If dietary treatments fail, drug therapy may be helpful. A number of drugs are available to prevent recurrences of calcium oxalate and other stones. Medications that inhibit the formation of stones include allopurinol, thiazide, potassium citrate, and potassium-magnesium citrate. In addition, drug treatments can sometimes also help prevent other complications related to stones, such as osteoporosis.

Correcting Underlying Conditions Known to Cause Kidney Stones. It is also important to treat and correct, if possible, any underlying disorder that may be causing stones to form. Such disorders include distal renal tubular acidosis, hyperthyroidism, sarcoidosis, and certain cancers. To prevent calcium stones that form in hyperparathyroid patients, a surgeon may remove the affected parathyroid gland (located in the neck). In most cases, only one of the glands is enlarged. Removing it ends the patient's problem with kidney stones.

Ear Infections

Middle ear (otitis media) infections are very common in young children. They include:

Acute otitis media (AOM) is an inflammation caused by bacteria that travel to the middle ear from fluid trapped in the Eustachian tube. Children with AOM exhibit signs of an ear infection including pain, fever, and tugging at the ear.
Otitis media with effusion (OME) refers to fluid that accumulates in the middle ear without obvious signs of infection. OME usually produces no symptoms, but some children will have difficulty hearing or complain of “plugged up” ears.

Prevention

Preventing colds and influenza (“flu”) is the best way to prevent ear infections. Make sure children wash their hands frequently and receive an influenza vaccine annually. The pneumococcal vaccine is also very helpful for preventing ear infections.

Treatment

Most ear infections resolve without antibiotic treatment.
For most children with AOM, doctors recommend waiting 48 - 72 hours before prescribing antibiotics. However, children younger than 6 months should receive immediate antibiotic treatment. Parents can give children 6 months and older ibuprofen or acetaminophen to help relieve pain.
Antibiotics are not helpful for most cases of OME. Doctors usually monitor children with OME for 3 months to see if their condition improves. Some children with hearing loss and developmental problems may eventually need surgery. Inserting tubes into the ear drum (tympanostomy) is the usual surgery for this problem.

Introduction

The ear is the organ of hearing and balance. It has three parts: the outer, middle, and inner ear.

The outer ear collects sound waves, which move through the ear canal to the tympanic membrane, commonly called the eardrum.
The tympanic membrane, or ear drum, is lined with mucus. When incoming sound waves strike this membrane, it vibrates like a drum, and converts the sound waves into mechanical energy.
This energy echoes through the middle ear. The middle ear is a complex structure filled with air and made of tiny bones. These bones vibrate to the rhythm of the eardrum and pass the sound waves on to the inner ear.
The inner ear is filled with fluid. Here, hair-like structures stimulate nerves to change sound waves into electrochemical impulses that are carried to the brain, which senses these impulses as sounds.
The inner ear also contains three semi-circular canals that function as the body's gyroscope, regulating balance.
The Eustachian tube, an important structure in the ear, runs from the middle ear to the passages behind the nose and the upper part of the throat. This tube helps equalizes the air pressure in the middle ear to the outside air pressure. Problems here are primary factors in most cases of ear infection.

The ear consists of external, middle, and inner structures. The eardrum and the three tiny bones conduct sound from the eardrum to the cochlea.

Acute Otitis Media (AOM). An inflammation in the middle ear is known as "otitis media." AOM is a middle ear infection caused by bacteria that traveled to middle ear from fluid build-up in the Eustachian tube. AOM may develop during or after a cold or the flu.

Middle ear infections are extremely common in children, but they are infrequent in adults.
In children, ear infections often recur, particularly if they first develop in early infancy.

Otitis Media with Effusion (OME). This condition occurs when fluid, called an effusion, becomes trapped behind the eardrum in one or both ears, even when there is no infection. In chronic and severe cases, the fluid is very sticky and is commonly called "glue ear."

It is usually not painful. Sometimes the only clue that it is present is a feeling of stuffiness in the ears, which can feel like "being under water."
It may impair children's hearing.
Children who are susceptible to OME can have frequent episodes for more than half of their first 3 years of life.
Most episodes will resolve within 3 months, but 30 - 40% of children may have recurrent episodes. Only 5 - 10% of episodes last longer than 1 year.

Chronic Otitis Media. This condition refers to persistent fluid behind the tympanic membrane without any infection present. It is called suppurative chronic otitis when there is persistent inflammation in the middle ear or mastoids, or chronic rupture of the eardrum with drainage.

Swimmer’s Ear (Acute Otitis Externa). Acute otitis externa (AOE) is an inflammation or infection of the outer ear and ear canal. It can be triggered by water that gets trapped in the ear. The trapped water can cause bacteria to breed. AOE can also be precipitated by overly aggressively scratching or cleaning ears or when an object gets stuck in the ears.

In 2006, the American Academy of Otolaryngology -- Head and Neck Surgery Foundation (AAO-HNSF) issued their first guidelines for management of AOE. A key recommendation is that AOE should be treated with topical (not oral) antibiotics. For pain relief, over-the-counter remedies such as acetaminophen or nonsteroidal anti-inflammatory drugs (such as ibuprofen) usually help, but in severe cases opioid drugs may be prescribed. With eardrops, most cases of AOE will clear up within 2 - 3 days.

Causes

Bacteria. Certain bacteria are the primary causes of acute otitis media (AOM). They are detected in about 60% of cases. The bacteria most commonly causing ear infections are:

Streptococcus pneumoniae (also called S. pneumoniae or pneumococcus) is the most common bacterial cause of acute otitis media, causing about 40 - 80% of cases in the U.S.
Haemophilus influenzae, the next most common culprit, is responsible for 20 - 30% of acute infections.
Moraxellacatarrhalis is responsible for 10 - 20% of infections.
Other bacteria include Streptococcus pyogenes and Staphylococcus aureus.

Viruses. Rhinovirus is a common virus that causes a cold and plays a leading role in the development of ear infections. It is not the direct infecting organism, however. But other viruses, such as respiratory syncytial virus (RSV, a virus responsible for childhood respiratory infections) and influenza (flu), may be the actual causes of some ear infections. Increasing evidence suggests that both viruses and bacteria play a role in ear infections. Viruses can increase middle ear inflammation and interfere with antibiotics’ efficacy in treating bacterial-causes ear infections. HIV or other immunocompromised states also increase the risk for ear infections.

Acute otitis media (middle ear infection) is usually due to a combination of factors that increase susceptibility to infections by specific organisms in the middle ear. The infection typically evolves as follows:

The primary setting for ear infections is in a child's Eustachian tube, which runs from the middle ear to the nose and upper throat. The Eustachian tube is shorter and smaller in children than adults, and therefore more vulnerable to blockage. It is also more horizontal in younger children and therefore does not drain as well.
Changes in middle ear pressure occur in about two-thirds of children with colds. Colds and respiratory infections are caused by viruses, such as the rhinovirus. Viruses play an important role in many ear infections, and can set the scene for a bacterial infection.
However, many bacteria normally thrive in the passages of the nose and throat. Most are not harmful. In fact, some can even block harmful bacteria from getting out of control. An additional defense system in the airways, such as mucus, prevents the harmful bacteria from spreading and infecting deeper passages, such as those in the ear.
If a cold does occur, the virus can cause the membranes along the walls of the inner passages to swell and obstruct the airways. If this inflammation blocks the narrow Eustachian tube, the middle ear may not drain properly. Fluid builds up. The defense systems described above become inefficient, and the fluid becomes a breeding ground for bacteria and subsequent infection.

Respiratory viruses may also contribute directly to the infection. Allergens can also produce inflammation and blockage in the Eustachian tube, which creates an environment favorable to bacteria.

The rise in ear infections has paralleled the increasing incidences of other upper and lower airway disorders such as asthma, allergies, and sinusitis. For example, the same bacteria are often responsible for both ear infections and sinusitis. In one study, 38% of children with ear infections also had sinusitis, and other studies have reported that nearly half of children with OME have concurrent sinusitis. Data indicate that nearly a third of infants and toddlers with upper respiratory infections go on to develop acute otitis media.

Medical or Physical Conditions that Affect the Middle Ear. Any medical or physical condition that reduces the ear's defense system can increase the risk for ear infections. Children with shorter than normal and relatively horizontal Eustachian tubes are at particular risk for initial and recurrent infections. Inborn structural abnormalities, such as cleft palate, increase risk. Genetic conditions, such as Kartagener's syndrome in which the cilia (hair-like structures) in the ear are immobile and cause fluid build up, also increase the risk. Children with Down syndrome or Fetal Alcohol Syndrome may also be at increased risk due to anatomical abnormalities.

Otitis media with effusion (OME) may occur spontaneously following an episode of acute otitis media. Susceptibility to OME may also be due to an abnormal or malfunctioning Eustachian tube that causes a negative pressure in the middle ear, which allows fluid to leak in through capillaries.

Risk Factors

Acute ear infections account for 15 - 30 million visits to the doctor each year in the U.S. In fact, ear infections are the most common reason why an American child sees the doctor. Furthermore, the rate of acute otitis media has been rising over the past decades.

Acute Otitis Media (AOM). About two-thirds of children will have a least one attack of AOM by age 3, and a third of these children will have at least 3 episodes. Boys are more likely to have infections than girls.

AOM generally affects children ages 6 - 18 months. The earlier a child has a first ear infection, the more susceptible they are to recurrent episodes (for instance, 3 or more episodes within a 6-month period).

As children grow, however, the structures in their ears enlarge and their immune systems become stronger. By 16 months, the risk for recurrent infections is rapidly declining. After age 5, most children have outgrown their susceptibility to any ear infections.

Otitis Media with Effusion. OME is very common in children aged 6 months to 4 years, with about 90% of children having OME at some point. More than 50% of children have OME before the age of 1, and more than 60% by age 2.

Ear infections are more likely to occur in the fall and winter. The following conditions also put children at higher risk for ear infection:

Allergies. Some experts believe that an increase in allergies is also partially responsible for the higher number of ear infections, which is unlikely to be related to day care attendance. Studies indicate that 40 - 50% of children over 3 years old who have chronic otitis media also have allergic rhinitis (hay fever). Allergies can cause inflammation in the airways, which may contribute to ear infections. Allergies are also associated with asthma and sinusitis. However, a causal relationship between allergies and ear infections has not been definitively established.
Enrollment in day care. Although ear infections themselves are not contagious, the respiratory infections that precipitate them can pose a risk for children with close and frequent exposure to other children. Some experts believe that the increase in ear and other infections may be due to the higher attendance of very small children, including infants, in day care centers beginning in the 1970s.
Exposure to second-had cigarette smoke. Parents who smoke pose a significant risk for both otitis media with effusion (OME) and recurrent acute otitis media (AOM) in their children. (Passive smoking does not appear to be a cause of initial ear infections, however.)
Being bottle-fed as infants. Babies who are bottle-fed may have a higher risk for otitis media than breastfed babies. The American Academy of Pediatrics recommends breastfeeding for at least the baby's first 6 months.
Pacifier use. Several studies have found that the use of pacifiers place children at even higher risk for ear infections. Sucking increases production of saliva, which helps bacteria travel up the Eustachian tubes to the middle ear.
Obesity. Obesity has been associated with the occurrence of OME.
Having siblings with recurrent ear infections.
Anatomical abnormalities of upper airways.

Symptoms

Symptoms of acute otitis media usually develop suddenly and can include:

Pain or discomfort in the ear. However, it is difficult to determine if an infant or child who hasn't yet learned to speak has an ear infection. Some children may indicate pain if they have trouble swallowing food and rejecting it. Some parents believe that tugging on the ear indicates an infection, but this gesture is more likely to indicate pain from teething.
Coughing
Nasal congestion
Fever
Irritability
Sleeplessness
Loss of appetite
Vomiting
Diarrhea
Listlessness

If the ear infection is severe, the tympanic membrane may rupture, causing the parent to notice pus draining from the ear. (This usually brings relief from pain.) Pus in the ear may cause hearing loss in some children.

Fevers and colds often make children irritable and fussy, so it is difficult to determine if acute otitis media is present as well. Symptoms are not apparent in about a third of children with acute middle ear infection.

OME often has no symptoms at all. Some hearing loss may occur, but it is often fluctuating and hard to detect, even by observant parents. The only sign to a parent that the condition exists may be when a child complains of "plugged up" hearing. Other symptoms can include loud talking, not responding to verbal commands, and turning up the television or radio.

Older children with OME may have difficulty targeting specific sounds in a noisy room. In such cases, some parents or teachers may attribute their behavior to lack of attention or even to an attention deficit disorder. OME is often diagnosed during a regular pediatric visit.

Prognosis

Doctors should carefully evaluate ear infections in infants fewer than 3 months old, and consider more serious infections, such as meningitis.

While severe cases of recurrent acute otitis media or persistent otitis media with effusion (OME) are associated with impaired hearing for a period of time, the long-term consequences resulting from this hearing loss may not be significant in most children.

Hearing loss in children may temporarily slow down language development and reading skills. However, results from a high quality study strongly indicate that uncomplicated chronic middle ear effusion poses no danger for developmental delays. Researchers evaluated children who had either prompt insertion of ear tubes to drain fluid when they were younger than age 3, or delayed insertion of tubes many months later. When the children were tested at ages 9 - 11, researchers found no differences in speech and language, auditory processing, attention, behavior, social skills, and academic achievement. As the majority of chronic ear effusion cases eventually clear up on their own, many experts now recommend against surgical intervention for most children.

Occasionally, patients with chronic otitis media develop involvement of the inner ear. In these situations hearing loss can potentially be permanent. Most of these patients will also have problems with vertigo.

Serious complications or permanent physical injuries from ear infections are very uncommon, but may include:

Structural damage. Certain children with severe or recurrent otitis media may be at risk for structural damage in the ear, including erosion of the ear canal.
Cholesteatomas. Cysts in the ear called cholesteatomas are an uncommon complication of recurrent or severe ear infections.
Calcifications. In rare cases, even after a mild infection, some children develop calcification and hardening in the middle and, occasionally, in the inner ear. This may be due to immune abnormalities.

Before the introduction of antibiotics, mastoiditis (an infection in the bones located in the skull), was a serious, albeit rare, complication of otitis media. This condition is difficult to treat and requires intravenous antibiotics and drainage procedures. Surgery may be necessary.

If pain and fever persist in spite of antibiotic treatment of otitis media, the doctor should check for mastoiditis. Most cases of mastoiditis are generally not associated with ear infections.

If an infection of the mastoid air cells cannot be controlled with antibiotics, surgery may be needed.

Impaired Balance. Some studies have indicated that children with chronic OME have problems with motor development and balance.

Facial Paralysis. Very rarely, a child with acute otitis media may develop facial paralysis, which is temporary and usually relieved by antibiotics or possibly drainage surgery. Facial paralysis may also occur for patients with chronic otitis media and a cholesteatoma (cyst in the middle ear). Surgery is often necessary to correct this condition.

Diagnosis

The doctor should be sure to ask the parent if the child has had a recent cold, flu, or other respiratory infection. If the child complains of pain or has other symptoms of otitis media, such as redness and inflammation, the doctor should rule out any other causes. These may include, but are not limited to, the following:

Otitis media with effusion. OME is commonly confused with acute otitis media. It must be ruled out because it does not respond to antibiotics.
Dental problems (such as teething).
Infection in the outer ear. Symptoms include pain, redness, itching, and discharge. Infection in the outer ear, however, can be confirmed by wiggling the ears, which will produce pain. (This movement will have no significant effect if the infection is in the middle ear.)
Foreign objects in the ear. This can be dangerous. A doctor should always check for this first when a small child indicates pain or problems in the ear.
Viral infection can produce redness and inflammation. Such infections, however, are not treatable with antibiotics and resolve on their own.
A parent's or child's attempts to remove earwax.
Intense crying can cause redness and inflammation in the ear.

Instruments Used for Examining the Ear. An ear examination should be part of any routine physical examination in children, particularly because the problem is so common and may not cause symptoms.

The doctor first removes any ear wax (called cerumen) in order to get a clear view of the middle ear.
The doctor uses a small flashlight-like instrument called an otoscope to view the ear directly. This is the most important diagnostic step. The otoscope can reveal signs of acute otitis media, bulging eardrum, and blisters.

An otoscope is a tool that shines a beam of light to help visualize and examine the condition of the ear canal and eardrum. Examining the ear can reveal the cause of symptoms such as an earache, the ear feeling full, or hearing loss.

To determine an ear infection, the doctor should always use a pneumatic otoscope. This device detects any reduction in eardrum motion. It has a rubber bulb attachment that the doctor presses to push air into the ear. Pressing the bulb and observing the action of the air against the eardrum allows the doctor to gauge the eardrum's movement.
Some doctors may use tympanometry to evaluate the ear. In this case, a small probe is held to the entrance of the ear canal and forms an airtight seal. While the air pressure is varied, a sound with a fixed tone is directed at the eardrum and its energy is measured. This device can detect fluid in the middle air and also obstruction in the Eustachian tube.
A procedure similar to tympanometry, called reflectometry, also measures reflected sound. It can detect fluid and obstruction, but does not require an airtight seal at the canal.

Neither tympanometry nor reflectometry are substitutes for the pneumatic otoscope, which allows a direct view of the middle ear.

Findings Indicating AOM or OME. A diagnosis of AOM requires all three of the following criteria:

History of recent sudden symptoms. Symptoms may include fever, pulling on the ear, pain, irritability, or discharge (otorrhea) from the ear.
Presence of fluid in the middle ear. This may be indicated by fullness or bulging of the eardrum or limited mobility.
Signs and symptoms of inflammation. These may include redness of the eardrum as well as assessment of the child's discomfort. Ear pain that is severe enough to interfere with sleep may indicate inflammation.

AOM (fluid and infection) is often difficult to differentiate from OME (fluid without infection). It is important for a doctor to make this distinction as OME does not require antibiotic treatment. In patients with OME, an air bubble may be visible and the eardrum is often cloudy and very immobile. A scarred, thick, or opaque eardrum may make it difficult for the doctor to distinguish between acute otitis media and OME.

Parents can also use a sonar-like device, such as the EarCheck Monitor, to determine if there is fluid in their child's middle ear. EarCheck uses acoustic reflectometry technology, which bounces sound waves off the eardrum to assess mobility. When fluid is present behind the middle ear (a symptom of AOM and OME), the eardrum will not be as mobile. The device works like an ear thermometer and is painless. Results indicate the likelihood of the presence of fluid and may help patients decide whether they need to contact their child's doctor. However, it is not recommended that children be treated with antibiotics based on the findings using this device.

On rare occasions the doctor may need to draw fluid from the ear using a needle for identifying specific bacteria, a procedure called tympanocentesis. This procedure can also relieve severe ear pain. This is most often performed by an ear, nose, and throat (ENT) specialist, and usually only in severe or recurrent cases. In most cases, tympanocentesis is not necessary in order to obtain an accurate enough diagnosis for effective treatment.

Hearing tests performed by an audiologist are usually recommended for children with persistent otitis media with effusion. A hearing loss below 20 decibels usually indicates problems.

Determining Impaired Hearing in Infants and Small Children. Unfortunately, it is very difficult to test children under 2 years old for hearing problems. One way to determine hearing problems in infants is to gauge the baby's language development:

At 4 - 6 weeks most babies with normal hearing make cooing sounds.
By around 5 months, infants should be laughing out loud and making one-syllable sounds with both a vowel and consonant.
Between 6 - 8 months, babies should be able to make word-like sounds with more than one syllable.
Usually starting around 7 months, and by 10 months, babies babble (making many word-like noises).
Around 10 months, babies can identify and use some term for a parent, such as dada, baba, or mama.
Babies speak their first word usually by the end of their first year.

If a child's progress is significantly delayed beyond these times, a parent should suspect possible hearing problems.

Determining Impaired Hearing in Older Children. Hearing loss in older children may be detected by the following behaviors:

They may not respond to speech spoken beyond 3 feet away.
They may have difficulty following directions.
Their vocabulary may be limited.
They may have social and behavioral problems.

Prevention

The best way to prevent ear infections is to prevent colds and flu.

Good Hygiene. Colds and flus are spread primarily when an infected person coughs or sneezes near someone else. A very common method for transmitting a cold is by shaking hands. Everyone should always wash their hands before eating and after going outside. Ordinary soap is sufficient. Waterless hand cleaners that contain an alcohol-based gel are also effective for everyday use and may even kill cold viruses. (They are less effective, however, if extreme hygiene is required. In such cases, alcohol-based rinses are needed.) Antibacterial soaps add little protection, particularly against viruses. In fact, one study suggests that common liquid dish washing soaps are up to 100 times more effective than antibacterial soaps in killing respiratory syncytial virus (RSV), which is known to cause pneumonia and has been associated with ear infections. Wiping surfaces with a solution that contains 1 part bleach to 10 parts water is very effective in killing viruses.

The American Academy of Pediatrics (AAP) and the U.S. Centers for Disease Control (CDC) recommend annual influenza vaccination for all children 6 months to 5 years of age. Preventing influenza (the "flu') may be a more important protective measure against ear infections than preventing bacterial infections. For example, studies report that children who are vaccinated against influenza experience a third fewer ear infections during flu season than unvaccinated children.

Flu Vaccines. Flu vaccines produce an immune response that attacks the active virus. Vaccines are typically given by injection, usually between October and December. Antibodies to the influenza virus generally develop within 2 weeks of vaccination, and immunity peaks within 4 - 6 weeks, then gradually wanes. An intranasal vaccine called FluMist is approved for children ages 2 years and older. FluMist is made from a live but weakened influenza virus; flu shots use inactivated (not live) viruses. Children younger than 2 years old, and children younger than age 5 who have asthma or recurrent wheezing, should not receive FluMist.

Possible side effects include:

Allergic Reaction. Newer vaccines contain very little egg protein, but an allergic reaction still may occur in people with strong allergies to eggs.
Soreness at the Injection Site. Up to two-thirds of people who receive the influenza vaccine develop redness or soreness at the injection site for 1 - 2 days afterward.
Flu-like Symptoms. Other side effects include mild fatigue and muscle aches and pains. They tend to occur between 6 - 12 hours after the vaccination and last up to 2 days. These symptoms are not influenza itself but an immune response to the virus proteins in the vaccine. Anyone with a fever, however, should not be vaccinated until the ailment has subsided.

Antiviral Drugs. Antiviral drugs are available to treat influenza. One such drug, oseltamivir (Tamiflu), is approved for use in children age 1 year and older. Studies report significant reduction in symptoms and in the incidence of ear infections with this drug. In another study, when the antiviral drug, zanamivir (Relenza), was administered in the nasal passages of adults with influenza, middle ear abnormalities were reduced by more than half, to 32%. This drug is available for children older than 7 years for treatment of influenza, but no research has determined its value for preventing or treating otitis media in children.

[For more information, see In-Depth Report #94: Colds and influenza.]

Preventive Antibiotics. Antibiotics have been used to prevent bacterial infections in children with recurrent ear infections (4 or more episodes a year). Studies suggest, however, that overall they only prevent 1 episode a year, and are not generally recommended for prevention, except for specific situations.

Pneumococcal Vaccine. The pneumococcal conjugate vaccine (PCV) protects against S. pneumoniae (also called pneumococcal) bacteria in children, the most common cause of middle ear infections, pneumonia, and other respiratory infections. It is included in the Recommended Childhood Immunization Schedule and is specifically approved for preventing otitis media. High quality evidence indicates these vaccinations could result in over 1.5 million fewer office visits, over 20% fewer procedures for tube implants, and significantly fewer antibiotic prescriptions. The recommended schedule of pneumococcal immunization is four doses, given at 2, 4, 6, and 12 - 15 months of age.

Still, the pneumococcal vaccine does not completely protect against otitis media. The current pneumococcal vaccine does not protect against all subtypes of S. pneumoniae. Also, other types of bacteria can cause the problem. Scientists are working on developing a new type of pneumococcal vaccine that combines S. pneumoniae and H. influenzae strains that are not influenced by the currently available H. influenzae vaccine. Researchers hope this investigational vaccine may eventually help prevent middle ear infection caused by these organisms.

Healthy Diet. Daily diets should include foods such as fresh, dark-colored fruits and vegetables, which are rich in antioxidants and other important food chemicals that help boost the immune system.

Probiotics ("Good" Bacteria). Researchers are studying the possible protective value of certain strains of lactobacilli, bacteria found in the intestines. Some of these strains, particularly acidophilus, are used to make yogurt. Studies have been mixed on probiotics’ benefits for preventing ear infections.

Xylitol. Xylitol, a sugar alcohol produced naturally in birch, strawberries, and raspberries, has properties that fight Streptococcal pneumonia bacteria. A few studies have reported that children who chew gum or swallow a syrup containing xylitol experience fewer ear infections, but other studies have not shown that xylitol is helpful.

Parents or others should not smoke around children. Several studies have found that children who live with smokers have a significant risk for ear infections.

Breastfeeding offers protection against many early infections, including ear infections. Mother's milk provides immune factors that help protect the child from infections. Also, infants are held during breast-feeding in a position that allows the Eustachian tubes to function well. In addition, a 2006 study suggested that breastfeeding can help protect even those children who are genetically susceptible to ear infections.

If possible, new mothers should breast-feed their infants for at least 4 - 6 months. According to the American Academy of Pediatrics, exclusively breast-feeding for a baby’s first 6 months helps to prevent ear and other respiratory infections. For bottle-fed babies, to improve protection mothers should not lay babies down with their bottle; they should hold the infants in the same way they would to breast-feed them.

Treatment

Treatments for ear infections cost the U.S. $3 - 4 billion each year, and many of these treatments, particularly heavy antibiotic use and surgical procedures, are often unnecessary in many children.

Experts continue to argue about the best approach for treating ear infections. The major debates rest on the use of antibiotics, surgery, and watchful waiting in both acute otitis media (AOM) and otitis media with effusion (OME).

Until recently, nearly every American child with an ear infection who visited a doctor received antibiotics. In one region of the U.S., more than 70% of children received antibiotics before they were 7 months old, and the most common reason for these medications was acute otitis media.

Major studies now indicate that antibiotics are unnecessary in most cases of acute otitis media. Between 80 - 90% of all children with uncomplicated ear infections recover within a week without antibiotics. Likewise, receiving antibiotics for an acute ear infection does not seem to prevent children from having fluid behind the ears after the infection is cleared up. Antibiotics are rarely recommended for otitis media with effusion.

Antibiotic Resistance. The intense and widespread use of antibiotics is leading to a serious global problem of bacterial resistance to common antibiotics. In the U.S., nearly a quarter of S. pneumoniae are currently resistant to at least three antibiotics. High rates of resistance strains are even being observed in infants. In general, regions and institutions with the highest rate of resistance are those in which antibiotics are the most heavily prescribed.

Watchful Waiting for AOM. Because of the high rate of antibiotic resistance, and the fact that non-severe AOM usually resolves on its own without antibiotics, many pediatric guidelines recommend a “watchful waiting” period before antibiotics are prescribed. Current guidelines released by the American Academy of Pediatrics and the American Academy of Family Physicians recommend an initial observation period of 48 - 72 hours for select children. Pain relief can initially be given with acetaminophen (Tylenol), ibuprofen (Advil), or topical benzocaine drops.

If there is no improvement or symptoms worsen, parents can schedule an appointment with the child's doctor to determine if antibiotics are needed. (Parents should contact the doctor within the first 24 hours if their child is 6 months or younger and has fever or other severe symptoms.) Another option is to ask the doctor for a Safety Net Antibiotic Prescription (SNAP) that can be filled if symptoms do not improve within 48 - 72 hours

While children with non-severe AOM given antibiotics may recover slightly more quickly, they often have a high number of side effects and antibiotic-resistant bacterial strains. Studies have found that giving parents the option of delaying antibiotic treatment helps to reduce the unnecessary use of antibiotics without causing any health problems for the children. Unfortunately, surveys indicate that although medical guidelines recommend watchful waiting, few doctors regularly practice it.

The American Academy of Pediatrics (AAP) and the American Academy of Family Physicians (AAFP) guidelines and recent evidence support the following recommendations:

Accurate diagnosis of AOM including differentiation from OME.
Children fewer than 6 months of age should receive immediate antibiotic treatment.
Children 6 months or older should be treated for pain within the first 24 hours with either acetaminophen or ibuprofen.
An initial observation period of 48 - 72 hours is recommended for select children to determine if the infection will resolve on its own without antibiotic treatment. (Most children do improve within 72 hours.)
For children aged 6 months - 2 years, criteria for recommending an observation period are an uncertain diagnosis of AOM and a determination that the AOM is not severe. For children older than 2 years, the observation period criteria are non-severe symptoms or uncertain diagnosis. Severe AOM symptoms include moderate to severe pain and a fever of at least 102.2° F (39° C).
Antibiotic prophylaxis may be recommended for recurrent acute otitis media. Which children should be treated this way, as well as which antibiotics and for how long, have not been clearly determined.

The American Academy of Pediatrics (AAP), the American Academy of Family Physicians (AAFP), and the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) released updated clinical practice guidelines for OME in 2004. These guidelines include the following treatment recommendations:

Watchful Waiting for OME. The child is typically monitored for the first 3 months. Antibiotics are not helpful for most patients with OME. For one, the condition resolves without treatment in nearly all children, especially those whose OME followed an acute ear infection. About 75 - 90% of OME cases that result from AOM resolve within 3 months. If OME last longer than 3 months, a hearing test should be conducted. Even if OME lasts for longer than 3 months, the condition generally resolves on its own without any long term effects on language or development and intervention may not be necessary. The doctor will re-evaluate the child at periodic intervals to determine if there is risk for hearing loss.

Drug Treatment. It is important for parents to recognize that persistent fluid behind the eardrum after treatment for acute otitis media does not indicate failed treatment. Antibiotics, decongestants, antihistamines and corticosteroids do not help and are not recommended for routine management of OME. These drugs are not effective for OME, either when used alone or in combination. Antihistamines and decongestants may cause more harm than good by provoking side effects such as stomach upset and drowsiness. At present, there is no compelling evidence to indicate that allergy treatment can assist with OME management nor has a causal relationship between allergies and OME been established.

Surgery. The decision to pursue surgery must be determined on an individual basis. Children with OME lasting longer than 4 months may be considered candidates for surgery if they have:

Hearing loss greater than 40 dB
Hearing loss between 21 - 39 dB (Children in this group may be observed or considered for surgery)
Hearing loss of 20 dB or less, when speech, language, or developmental problems are observed
OME and structural damage to the ear canal, eardrum, or middle ear

Tympanostomy (the insertion of tubes into the eardrum) is the first choice for surgical intervention. Adenoidectomy (removal of adenoids) plus myringotomy (removal of fluid), with or without tube insertion, is sometimes recommended as a repeat surgical procedure. (Myringotomy alone is not recommended for OME treatment. Between 20 - 50% of children who undergo this procedure may have OME relapse and need additional surgery). Tube insertion may be advised for children younger than 4 years of age. Adenoidectomy is not recommended as an initial procedure unless some other condition (chronic sinusitis, nasal obstruction, adenoiditis) is present.

Tonsillectomy (removal of tonsils) is not recommended for OME treatment.

Home Remedies

Careful monitoring of the child's condition (watchful waiting) along with home remedies may be a viable alternative to antibiotic treatment for many children with a first episode of acute otitis media. However, in some situations parents should contact their medical professional immediately:

Seek immediate medical attention for high fever, severe pain, or other signs of complications.
Parents of infants should contact their doctor immediately if they have any fever, regardless other symptoms.

Before antibiotics, parents used home remedies to treat the pain of ear infections. Now, with current concern over antibiotic overuse, many of these remedies are again popular.

Depending on regional cultures, parents may have pressed a warm water bottle or warm bag of salt against the ear. Such old-fashioned remedies may still help to ease ear pain.
Due to the high risk of burns, ear candles should not be used to remove wax from ears. There is no evidence to indicate that these candles are safe or effective for treatment of AOM or other ear conditions.

Herbal remedies are not standardized or regulated, and their quality and safety are largely unknown. Parents should never give their child herbal remedies, including oral remedies, without approval from a doctor.

Valsalva's Maneuver. A simple technique called the Valsalva's maneuver is useful in opening the Eustachian tubes and providing occasional relief from the chronic stuffy feeling accompanying otitis media with effusion. It may also be useful for unplugging ears during air travel descent as well. It works as follows:

The child takes a deep breath and closes the mouth.
The child then blows the nose gently while, at the same time, pinching it firmly shut.
The parent should be sure to instruct the child not to blow too hard or the eardrum could be harmed.

Do not use this technique if an infection is present.

A number of pain relievers are available to help relieve symptoms.

Either acetaminophen (Tylenol) or ibuprofen (Advil) is the pain-reliever of choice in children.
Older children may be able to take prescription pain relievers that contain codeine if the pain is severe.
Eardrops containing anesthetics (Auralgan) are also available by prescription. Auralgan provides short-acting pain relief and may help children endure ear discomfort until an oral pain reliever takes effect. Parents should check with a doctor before using them. Eardrops could cause damage in children who have a ruptured eardrum. This might be indicated by fluid drainage from the ear canal.

Note: Aspirin and aspirin-containing products are not recommended for children or adolescents. Reports of Reye syndrome, a very serious condition, have been associated with aspirin use in children who have chicken pox or flu.

Many non-prescription products are available that combine antihistamines, decongestants, and other ingredients, and some are advertised as cold remedies for children. Researchers have found little or no benefits for acute otitis media or for otitis media with effusion using decongestants (either oral or nasal sprays or drops), antihistamines, or combination product. Their use is not recommended for AOM or OME. Recent research has questioned the general safety of these products and they are currently banned for use in children under age 2 years.

Swimming can pose specific risks for children with current ear infections or previous surgery. Water pollutants or chemicals may exacerbate the infection, and underwater swimming causes pressure changes that can cause pain. The following precautions should be taken:

Children with ruptured acute otitis media (drainage from ear canal) should not go swimming until their infections are completely cured.
Children with AOM that is not ruptured should not dive or swim underwater.
Some doctors recommend that children with implanted ear tubes should use earplugs or cotton balls coated in petroleum jelly when swimming to prevent infection. Others say earplugs are only necessary if the child will be diving underwater. Parents should consult their child's doctor.

Medications

When antibiotics are needed, a number of different classes are available for treating acute ear infections. Amoxicillin is a penicillin antibiotic and the drug of first choice. Other antibiotics are available for children who are allergic to penicillin or who do not respond within 2 - 3 days.

Duration. If a child needs antibiotics for acute otitis media, experts recommend they be taken for the following periods of time:

A 10-day course of antibiotics is usually recommended for children younger than 6 years of age, and for those with severe AOM.
Antibiotic therapy for 5 - 7 days is recommended for children 6 years of age or older with mild-to-moderate symptoms.

Parents should be sure their child finishes the entire course of therapy. Failure to finish is a major factor in the growth of bacterial strains that are resistant to antibiotics.

What to Expect. Earaches usually resolve within 24 hours after taking an antibiotic, although about 10% of children who are treated do not respond. This may occur when a virus is present or if the bacteria causing the ear infection is resistant to the prescribed antibiotic. A different antibiotic may be needed.

In some children whose treatment is successful, fluid will still remain in the middle ear for weeks or months, even after the infection has resolved. During that period, children may have some hearing problems, but eventually the fluid almost always drains away. Antibiotics should not be used to treat residual fluid.

Follow-Up. Your child should return to the doctor's office:

Two to 3 weeks after therapy, if initial therapy cleared up the infection and the child is less than 15 months old, or has risk factors for reinfection
Three to 6 weeks after treatment, if initial therapy cleared up the infection and the child is older than 15 months old and has no specific risk factors
Within 48 hours of taking the last antibiotic dose if signs of infection are still present (for example, there is still pus in the ear)

When suspecting complications, consult with an ear, nose, and throat specialist (otolaryngologist) . This specialist may perform a tympanocentesis or myringotomy, procedures in which fluid is drawn from the ear and examined for specific organisms. But, this is reserved for severe cases.

The selection of an antibiotic is determined in part by the severity of the child's condition as well as a history of response/non-response to antibiotic therapy. Treatment decisions take into account whether the child's condition is severe or non-severe.

Amoxicillin is generally recommended for first-line treatment of AOM. The combination drug amoxicillin-clavunate is prescribed for patients who have severe pain or a fever higher than 102.2° F(39° C). Other drug classes may be prescribed if a child is allergic to penicillin or does not respond to the initial therapy.

The following treatment guidelines provide general recommendations based on the severity of a child's AOM.

First-line treatment for non-severe AOM:

Amoxicillin 80 - 90 mg/kg per day orally. Amoxicillin is a penicillin antibiotic.

If the patient has an allergy or a history of non-response to penicillin drugs, one of the following antibiotics may be prescribed:

Azithromycin or clarithromycin. These drugs are in the macrolide class and are administered orally.
Cefdinir, cefuroxime, or cefpodoxime. These drugs, classified as cephalosporins, are taken by mouth. They may cause reactions in penicillin-allergic patients.

If the patient does not respond to amoxicillin or alternative antibiotic drugs after 48 - 72 hours, one of the following drugs may be prescribed:

Amoxicillin-clavulanate, clindamycin, or ceftriaxone. Ceftriaxone is injected intramuscularly. The other two drugs are administered orally. Each of these drugs is a different type of antibiotic. Amoxicillin-clavulanate (Augmentin) is classified as a penicillin; ceftriaxone (Rocephin) is a cephalosporin; clindamycin (Cleocin) is a lincosamide.

First-line treatment for severe AOM:

Amoxicillin-clavulanate (Augmentin). This antibiotic is known as an augmented penicillin. It works against a wide spectrum of bacteria and is administered orally.

Second-line treatment for severe AOM:

Ceftriaxone. Ceftriaxone (Rocephin) is an injectable cephalosporin that may be prescribed as an alternative to amoxicillin-clavulanate, especially for children who have vomiting or other conditions that hamper oral administration.
Tympanocentesis or clindamycin. Patients with severe AOM who have failed to respond to amoxicillin-clavulanate after 48 - 72 hours may require the withdrawal of fluid from the ear (tympanocentesis) in order to identify the bacterial strain causing the infection. If tympanocentesis cannot be performed, clindamycin may be prescribed orally to treat penicillin-resistant pathogens that have not responded to prior drug therapy.

The most common side effects of nearly all antibiotics are gastrointestinal problems, including cramps, nausea, vomiting, and diarrhea. This can be a significant problem in infants and small children. One study reported that giving such children a soy-based formula that contained fiber (Isomil DF) was helpful in reducing these side effects.
Amoxicillin use during infancy may lead to enamel defects and discolorations of permanent teeth.
Allergic reactions can also occur with all antibiotics but are most common with medications derived from penicillin or sulfa. These reactions can range from mild skin rashes to rare but severe, even life-threatening, anaphylactic shock.
Some drugs, including certain over-the-counter medications, interact with antibiotics. Parents should tell the doctor about all medications their children are taking.

Surgery

A tympanostomy involves the insertion of tubes to allow fluid to drain from the middle ear. The procedure involves:

A general anesthetic (asleep, no pain). Children typically recover completely within a few hours.
Myringotomy (removal of fluid) is performed first.
After myringotomy, the doctor inserts a tube to allow continuous drainage of the fluid from the middle ear.

Postoperative Effects. Tympanostomy is a simple procedure, and the child almost never has to spend the night in the hospital. Acetaminophen (Tylenol) or ibuprofen (Advil) is sufficient for any postoperative pain in most children. Some children, however, may need codeine or other powerful pain relievers.

Generally, the tubes stay in the eardrum for at least several months before coming out on their own. On rare occasions, they will need to be surgically removed.

Complications. Otorrhea, drainage of secretion from the ear, is the most common complication after surgery and can be persistent in some children. It is usually treated with antibiotic eardrops. One study suggests that wearing earplugs may help the problem.

More serious complications from the operation are very uncommon, but may include:

General anesthetic risks. Rarely, allergic reactions or other complications, such as throat spasm or obstruction, may occur. The risk is highest in children who have other medical conditions, most commonly upper respiratory infections, lung disease, or GERD. Anesthetic-related risks are nearly always easily treated.
Tube blockage. Sometimes the tubes become blocked from sticky secretions or clotted blood after the operation.
Persistent eardrum perforation. This condition occurs when the eardrum does not close after the tubes have come out. It is the most common serious complication, but it is very rare.
Scarring can also occur, particularly in children who need more than one procedure, but it almost never affects hearing.
Small keratin (skin cell) containing cysts called cholesteatomas develop around the tube site in around 1% of patients.

Success Rates. Hearing is almost always restored following tympanostomy. Failure to achieve normal or near-normal hearing is usually due to complicated conditions, such as preexisting ear problems or persistent OME in children who have had previous multiple tympanostomies. Persistent fluid is the main reason for continued impaired hearing. Only a small percentage of hearing loss cases can be attributed to complications of the operation itself.

Earplugs as a Precaution. Many doctors feel that children should use earplugs when swimming while the tubes are in place in order to prevent infection. Others feel that as long as the child does not dive or swim underwater, earplugs may not be necessary. Parents should talk to their child's doctor about this subject. Cotton balls coated with petroleum jelly are effective alternatives to ear plugs. Children do not need to wear earplugs while showering.

Follow-Up. Eventually, the tubes fall out as the hole in the eardrum closes. This may happen after several months or more than a year later. It is painless. In fact, the patient and parents may not even be aware that the tubes are out.

About 20 - 50% of children may have OME relapse and need additional surgery that involves adenoidectomy and myringotomy. Tube reinsertion may be recommended for children younger than 4 years of age.

Myringotomy is used to drain the fluid and may be used (with or without ear tube insertion) in combination with adenoidectomy as a repeat surgical procedure if initial tympanostomy is not successful. It is not effective as a sole surgical procedure. Myringotomy involves the following steps:

The surgeon makes a very small incision in the eardrum.
Fluid is sucked out using a vacuum-like device.
The fluid is usually examined for identifying specific bacteria.
The eardrum heals in about a week.

Adenoids are collections of spongy lymph tissue in the back of the throat, similar to the tonsils. Removal of the adenoids, called adenoidectomy, is usually only considered for OME if a pre-existing condition exists such as chronic sinusitis, nasal obstruction, or chronic adenoiditis (inflammation of the adenoids). Unless these conditions exist, adenoidectomy is not recommended for treatment of OME.

Adenoidectomy plus myringotomy (removal of fluid) may be performed if an initial tympanostomy (tube insertion) procedure is unsuccessful in resolving OME. This combination procedure works best in children ages 4 years or older. Tube insertion is recommended for children under 4 years of age. It is not necessary to perform an adenoidectomy along with tube insertion for children under 4 years of age.

Laser-assisted myringotomy is a technique that is being investigated as an alternative to conventional tympanostomy and myringotomy. At present, there is not enough evidence to say whether it is as good as ear tubes, the standard procedure. Some clinical trials have suggested that the success rate for laser-assisted myringotomy is half that of standard tympanostomy/myringotomy. Many insurance companies consider laser-assisted myringotomy to be an investigational procedure and will not pay for it.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Gastroesophageal reflux disease (GERD) is a condition in which contents of the stomach or small intestine repeatedly move back up into the esophagus (the tube connecting the throat to the stomach). This regurgitating action is called reflux. Reflux causes heartburn, and although most people have an attack of heartburn at some point in their lives, persistent reflux and severe heartburn may indicate GERD.

Signs and Symptoms

Heartburn -- a burning sensation under the sternum in the chest -- is the primary symptom of GERD. Heartburn often occurs after a meal and worsens at night, when you are lying flat. It is more likely to occur following a heavy meal, or if you bend, lift, or lie down just after eating.

Other symptoms of GERD include:

Regurgitation of food
Belching
Nausea and vomiting
Chronic cough, wheezing
Sore throat, hoarseness or change in voice, difficulty swallowing
Chest pain

GERD is common in infants and young children, but is generally mild. If an infant has the following symptoms, however, call a doctor as soon as possible:

Ongoing coughing
Wheezing, gasping
Severe vomiting
Frequent burping

Causes

Normally when a person swallows, the muscular walls of the esophagus move in waves to push the food down into the stomach. Right after the food enters the stomach, a band of muscle (the lower esophageal sphincter, or LES) closes off the esophagus. If the muscle fails to close tightly enough or weakens over time, the stomach contents can back up into the esophagus, causing heartburn and other symptoms of GERD.

Substances in the digestive juices from the stomach (such as acid, pepsin, and bile) can damage the inner lining of the esophagus, causing inflammation ulcers (open sores), and, possibly, precancerous changes to cells (called Barrett's esophagus).

Any of the following may compromise the LES:

Pregnancy
Obesity
Hiatal hernia (a condition in which a portion of the stomach protrudes through an opening in the diaphragm where the esophagus normally fits snuggly and passes into the stomach)
Recurrent or persistent vomiting
Nasogastric tubes (these are inserted through the nose and into the stomach for a variety of medical reasons)
Smoking cigarettes
Some medicines, including calcium channel blockers (a class of meds used for high blood pressure such as amlodipine, diltiazem, felodipine, nifedipine, nisoldipine, and verapamil), anticholinergic drugs (including benztropine, biperiden, dicyclomine, hyoscyamine, isopropamide, and scopolamine), iron pills, non-steroidal anti-inflammatory drugs (NSAIDs including aspirin and ibuprofen), potassium, dopamine (for Parkinson's disease), sedatives, bisphosphonates (alendronate and risedronate for osteoporosis), and beta blockers (such as atenolol, labetalol, metoprolol, nadolol, pindolol, and propranolol, for high blood pressure or heart disease)

Risk Factors

Heavy meals
Lying down or bending after a meal
Eating immediately prior to exercise
Prior esophageal surgery
Esophageal stricture (narrowing of the esophagus)
Cigarette smoking
Alcohol intake
Psychological stress

Children with the following conditions are at particular risk for GERD:

Neurologic impairment
Food allergies
Scoliosis
Frequent vomiting
Cystic fibrosis
Digestive disorders

Diagnosis

GERD is generally not difficult to diagnose. Your symptoms, what you eat and drink, medications you are taking, and your lifestyle are usually enough to make a clear diagnosis. If the diagnosis is unclear to your doctor, one or more tests may be performed:

Upper endoscopy, called esophageal gastroduodenoscopy (EGD), which involves the insertion of a tube down your throat into the esophagus to look for signs of reflux, inflammation, ulcers, or other changes in the esophagus.
A barium swallow, which involves visualization of the esophagus through a series of x-rays following the swallowing of a substance called barium. This looks at the movement of the esophagus and whether any fluid comes back from the stomach into the esophagus.
Manometry measures the pressure of the sphincter muscle. If the pressure is low, this is consistent with GERD.

Treatment

The primary goals of treatment are to reduce the reflux (regurgitation), stop the harmful effect of the stomach's materials by reducing its acid content, improve the clearance of food through to the stomach, and protect the walls of the esophagus.

For mild cases, these goals can be accomplished by making lifestyle changes (such as avoiding certain foods) and by taking over-the-counter medication. Health care professionals may recommend herbs such as DGL-licorice (Glycyrrhiza glabra ) for their soothing properties. Prescription medicines may be recommended as needed.

For moderate-to-severe cases, prescription medication may be used more regularly, and the condition may be monitored more closely. If these measures fail, surgery may ultimately be required.

Lifestyle

Making changes to or avoiding certain habits can go a long way to relieving or preventing your symptoms of GERD.

The following are typical suggestions for people with GERD:

Avoid behavior that does not allow food to easily move down into and through the stomach. This includes bending, lying down, or participating in jarring exercises soon after a meal.
Don't eat heavy meals.
Avoid acidic foods and drinks. These include caffeinated beverages, decaffeinated coffee, and orange juice.
Avoid alcohol, chocolate, spearmint, and peppermint. These can relax the lower esophageal sphincter.
Avoid carbonated beverages.
Avoid eating fatty foods, including full-fat milk, which also may relax the lower esophageal sphincter tone. Take medication with plenty of water.
Lose weight if you are overweight.
Quit smoking.
Avoid medications that provoke symptoms. These include smooth-muscle relaxants, such as calcium channel blockers (including amlodipine, diltiazem, felodipine, nifedipine, nisoldipine, and verapamil, which are used for high blood pressure), anticholinergic drugs (including benztropine, biperiden, dicyclomine, hyoscyamine, isopropamide, and scopolamine), iron pills, non-steroidal anti-inflammatory drugs (NSAIDs including aspirin and ibuprofen), potassium, dopamine (for Parkinson's disease), sedatives, bisphosphonates (alendronate and risedronate for osteoporosis), and beta blockers (such as atenolol, labetalol, metoprolol, nadolol, pindolol, and propranolol, for high blood pressure or heart disease).

If you experience more frequent symptoms at night, you may be relieved by:

Raising the head of your bed about 6 inches.
Avoiding bedtime snacks.

Stress may worsen symptoms. Therefore, relaxation, such as yoga, tai chi, or meditation, is worth considering as part of your treatment plan.

Medications

The main aim of drug treatment is to control the acidity of the stomach. This can be achieved with either nonprescription or prescription drugs, depending on the severity and frequency of your reflux. Your doctor will determine which medicine is best for you.

There are several different types of medications used for GERD, and each works in a different way. Over-the-counter antacids neutralize the stomach acids. Histamine H2 blockers interfere with the production of acid, and proton pump inhibitors suppress molecules in the glands responsible for the release of acid. Avoid taking other medications within 3 hours of an antacid because antacids may limit the absorption of other drugs.

Antacids, available over the counter, may relieve heartburn or indigestion. Antacids include aluminum hydroxide (Amphojel, AlternaGEL), magnesium hydroxide (Phillips' Milk of Magnesia), aluminum hydroxide and magnesium hydroxide (Maalox, Mylanta), calcium carbonate (Rolaids, Titralac, Tums), and sodium bicarbonate (Alka-Seltzer). Antacids may block medications from being absorbed and thereby decrease the medicine's effectiveness. It is recommended to take antacids at least 1 hour before or 2 hours after taking medications. Ask your pharmacist or doctor for more information.
H2 blockers, such as cimetidine (Tagemet), ranitidine (Zantac), nizatidine (Axid), and famotidine (Pepcid), reduce gastric acid secretion.
Proton-pump inhibitors, including esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec), pantoprazole (Protonix), and rabeprazole (Aciphex), decrease gastric acid production.
Sucralfate (Carafate) makes a coating over the ulcer crater, protecting it from further damage.
Prokinetic agents, specifically metoclopramide (Reglan), promote movement of stomach acids along the gastrointestinal tract, rather than backing up into the esophagus.

Surgery and Other Procedures

For a small number of people, diet, medication, and lifestyle changes are not enough to relieve symptoms of GERD. In such cases, a surgical procedure called fundoplication may be performed to prevent reflux and repair a hiatal hernia (a condition that may cause GERD). As many as 90% of people who have had this operation report no longer having heartburn.

Nutrition and Dietary Supplements

Nutritional therapy is one of the first treatments recommended for GERD.

Doctors used to recommend eating bland foods with milk and only small amounts of food with each meal. Following these nutritional tips may help reduce symptoms:

Eat antioxidant foods, including fruits (such as blueberries, cherries, and tomatoes), and vegetables (such as squash and bell peppers).
Eat foods high in B-vitamins and calcium, such as almonds, beans, whole grains (if no allergy), dark leafy greens (such as spinach and kale), and sea vegetables.
Avoid refined foods, such as white breads, pastas, and especially sugar.
Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy) or beans for protein.
Use healthy oils, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Avoid beverages that can irritate the lining of the stomach or increase acid production including coffee (with or without caffeine), alcohol, and carbonated beverages.
Drink 6 - 8 glasses of filtered water daily.
Exercise at least 30 minutes daily, 5 days a week.

Nutritional deficiencies may be addressed with the following supplements:

A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-vitamins, and trace minerals, such as magnesium, calcium, zinc, and selenium.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tablespoonful oil 2 - 3 times daily, to help decrease inflammation and improve immunity. Cold-water fish, such as salmon or halibut, are good sources, but supplementation is recommended.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, for maintenance of gastrointestinal and immune health. Some probiotic supplements may need to be refrigerated for best results. Your child may also take probiotic supplements. Consult with your health care provider before giving your child any dietary supplements.
Alpha-lipoic acid, 25 - 50 mg twice daily, for antioxidant support.
Melatonin, 2 - 6 mg at bedtime, for immune support and gastric protection.
Vitamin C, 500 - 1,000 mg one to three times daily, as an antioxidant and for immune support.
L-glutamine, 500 - 1,000 mg 3 times daily, for support of gastrointestinal health and immunity.
Grapefruit seed extract (Citrus paradisi), 100 mg capsule or 5 - 10 drops (in favorite beverage) 3 times daily when needed, for antibacterial, antifungal, and antiviral activity, and for immunity.
Resveratrol (from red wine), 50 - 200 mg daily, to help decrease inflammation and for antioxidant effects.

Herbs

Herbs are generally a safe way to strengthen and tone the body's systems. As with any therapy, you should work with your health care provider to get your problem diagnosed before starting any treatment. You may use herbs as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, you should make teas with 1 tsp. herb per cup of hot water. Steep covered 5 - 10 minutes for leaf or flowers, and 10 - 20 minutes for roots. Drink 2 - 4 cups per day. You may use tinctures alone or in combination as noted.

Green tea (Camelia sinensis) standardized extract, 250 - 500 mg daily, for antioxidant, anti-inflammatory, and heart health effects. Use caffeine-free products. You may also prepare teas from the leaf of this herb.
Cat's claw (Uncaria tomentosa) standardized extract, 20 mg 3 times a day, for inflammation and antibacterial or antifungal activity.
Reishi mushroom (Ganoderma lucidum), 150 - 300 mg 2 - 3 times daily, for inflammation and for immunity. You may also take a tincture of this mushroom extract, 30 - 60 drops 2 - 3 times a day.
Olive leaf (Olea europaea) standardized extract, 250 - 500 mg 1 - 3 times daily, for antibacterial or antifungal activity and immunity. You may also prepare teas from the leaf of this herb.
DGL-licorice (Glycyrrhiza glabra) standardized extract, 250 - 500 mg 3 times daily, chewed either 1 hour before or 2 hours after meals. Glycyrrhizin is a chemical found in licorice that causes side effects and drug interactions. DGL is deglycyrrhizinated licorice, or licorice with the glycyrrhizin removed.
Mastic (Pistacia lentiscus) standardized extract, 1,000 - 2,000 mg daily in divided dosages, for activity against H. Pylori.
Tumeric (Curcuma longa) standardized extract, 300 mg 3 times a day, for pain and inflammation.

Homeopathy

Although few studies have examined the effectiveness of specific homeopathic therapies, professional homeopaths may consider the following remedies for the treatment of GERD symptoms based on their knowledge and experience. Before prescribing a remedy, homeopaths take into account your constitutional type - your physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate treatment for each individual.

Pulsatilla -- for heartburn, queasiness, a bad taste in the mouth brought on by eating rich foods and fats (especially ice cream); symptoms may include vomiting partly digested food. This remedy is most appropriate for an individual whose tongue is coated with a white or yellow substance.
Ipecacuahna -- for persistent and severe nausea, with or without vomiting and diarrhea, caused by an excess of rich or fatty foods.
Carbo vegetabilis -- for bloating and indigestion, especially with flatulence and fatigue.
Nux vomica -- for heartburn, nausea, retching without vomiting, and sour burps caused by overeating, alcohol use, or coffee drinking. This remedy is most appropriate for individuals who also feel irritable and sensitive to noise and light.

Other Considerations

Pregnancy

GERD is quite common during pregnancy, particularly in the third trimester.

Warnings and Precautions

Contact your health care provider if the medication recommended does not help or if you experience side effects, such as cramping or diarrhea.

Prognosis and Complications

The acidic contents of the stomach can damage the esophagus, causing narrowing, ulcers, erosion, and precancerous changes to cells known as Barrett's esophagus. GERD can also result in respiratory diseases, ear, nose, throat conditions, and tooth decay. Most people can effectively manage their symptoms with lifestyle modifications and medications.

Brand Name(s)

There may be other brand names for this medicine.

When This Medicine Should Not Be Used

You should not use this medicine if you have had an allergic reaction to mometasone. Do not use this medicine to treat an asthma attack that has already started.

How to Use This Medicine

Powder

Your doctor will tell you how much of this medicine to use and how often. Do not use more medicine or use it more often than your doctor tells you to.
This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
You will use this medicine with a device called an inhaler. The inhaler holds the powdered medicine and measures out each dose for you. Your caregiver will show you how to use your inhaler.
Write down the date when you first open the foil package. The medicine is good for only 45 days once the package is opened.
The inhaler has a small window on the side with numbers showing. This is the dose counter. It keeps track of how many more times you can use the inhaler before you need to open a new one. When the dose counter reaches "00," the inhaler will lock itself. If the dose counter is not working correctly, do not use the inhaler and return it to your pharmacy or doctor.
Hold the inhaler upright and twist the cap to the left to open it. The dose counter should change to a lower number when you take off the cap. The arrow on the inhaler should be pointing to the dose counter.
To inhale this medicine:
- Breathe out fully, trying to get as much air out of your lungs as possible.
- Put the mouthpiece in your mouth and close your lips around it. The inhaler will be sideways.
- Take a fast, deep breath.
- Take the inhaler out of your mouth. Hold your breath for about 10 seconds, then breathe out slowly. Do not breathe out into the inhaler.
Wipe the mouthpiece dry with a cloth or tissue. Do not wash it with water. Put the cap back on right away and twist it to the right. You should hear a "click" when the cap is fully closed.
Rinse your mouth out with water.
You might need to use this medicine for 1 to 2 weeks before your asthma starts to improve.

If a dose is missed:

If you miss a dose or forget to use your medicine, use it as soon as you can. If it is almost time for your next dose, wait until then to use the medicine and skip the missed dose. Do not use extra medicine to make up for a missed dose.

How to Store and Dispose of This Medicine

Keep the inhaler in the foil pouch until you are ready to use it the first time. Store the inhaler at room temperature, away from heat, moisture, and direct light.
Throw away the inhaler when the dose counter is at "00" or 45 days after you opened the package. Ask your pharmacist, doctor, or health caregiver about the best way to dispose of the used inhaler and any leftover medicine.
Keep all medicine away from children and never share your medicine with anyone.

Drugs and Foods to Avoid

Warnings While Using This Medicine

Make sure your doctor knows if you are pregnant or breastfeeding, or if you have tuberculosis (TB).
If your treatment is being changed from oral medicine to this inhaled medicine:
- Follow your doctor's directions very carefully. It might take some time for your body to adjust to the change. This medicine may not affect your whole body the way that oral steroid medicines do.
- Make sure you know what to do if you have a severe asthma attack.
- Tell your doctor right away if you have nausea or vomiting, your joints hurt, or you feel unusually tired, weak, dizzy, lightheaded, or sad. Also tell your doctor if you start to have a runny or stuffy nose, a skin rash, or itchy or watery eyes.

If any of your asthma medicines do not seem to be working as well as usual, call your doctor right away. Do not change your doses or stop using your medicines without asking your doctor.
