Partner Yoga Pose: Double Child

FitSugar — Thu, 17 Jan 2008 11:45:00 -0800

While it's true that many Partner Yoga poses can help you get a deeper stretch, another benefit is the emotional support you share. Energy can be passed and received between you, so doing a pose with someone can instill a sense of joy and serenity. This one, called Double Child, will help to relieve stress and calm the mind.

Partner one (blue shirt) and partner two (tan shirt) kneel down on a mat with their feet touching.
Both partners come into Child's Pose and hold hands.
They remain here for at least five breaths, allowing the lower back, hips, and shoulders to release.
After they've had enough, both partners slowly sit up.

I know this pose doesn't look like much, but it's one of those things that you just have to try. Once both partners allow themselves to relax completely, they'll feel the amazing effects.

Stretch It: Grounded Tipover Tuck

FitSugar — Thu, 10 Sep 2009 14:05:33 -0700

I'm always in need of a good neck and shoulder stretch. Tipover Tuck is one of my favorites, but here's a more relaxing version.

To see a photo of how to begin this stretch read more.

Come into Child's Pose with your shins and forehead on the floor. Stay here for a few breaths, working on lengthening your spine as you relax your chest to your thighs. When you're ready, interlace your hands behind you in a double fist. If you can, press the heels of your palms together to increase the stretch in your shoulders. Then lift your hands as high as you can.

Inhale to shift your weight forward and lift your hips off your heels. Come to rest on the crown (top) of your head and extend your hands as close to the floor as you can. Stay here for 10 seconds and then lower your hips back to your heels. Stay here for 10 seconds, and then lift your hips up again. Continue this cycle five or more times, then release into Child's Pose with your arms on either side of your legs.

Otitis media

FitSugar — Wed, 08 Oct 2008 17:35:25 -0700

HEALTH GUIDE REFERENCE FROM A.D.A.M

Otitis media is an infection of the middle ear, the area just behind the eardrum. It happens when the eustachian tubes, which connect the middle ear to the nose, become blocked with fluid. With the infection, mucus, pus, and bacteria can also pool behind the eardrum, causing pressure and pain. Ear infections usually begin with a cold. Although adults can get ear infections, they are most common in infants and young children. That's because a child's eustachian tubes are narrower and shorter than an adults, and it's easier for fluid to get trapped in the middle ear. Ear infections usually clear up on their own. Although it was common for doctors to give antibiotics to children with ear infections, now guidelines from the American Academy of Pediatricians suggest taking a wait-and-see approach for the first 72 hours.

With a severe ear infection, pressure may build up and cause the eardrum to rupture. Pus and blood may drain out. This usually relieves pain and pressure, and in most cases the eardrum heals on its own.

Signs and Symptoms

There are two main types of ear infections: acute otitis media (AOM), and otitis media with effusion (OME), where fluid remains trapped in the ear even after the infection is gone.

Acute otitis media causes pain, fever, and difficulty in hearing. If a child is too young to talk, signs of an ear infections can include crying, irritability, trouble sleeping, and pulling on the ears.

Other symptoms that may be associated with an ear infection include sore throat (pharyngitis), neck pain, nasal congestion and discharge (rhinitis), headache, and ringing (tinnitus), buzzing, or other noise in the ear.

Causes

Blockage of the eustachian tubes may be caused by:

Respiratory infection (cold)
Allergies
Exposure to cigarette smoke
Infected or overgrown adenoids (tonsils)
For infants, being fed lying down (drinking a bottle while lying on the back)

Ear infections occur most often in the winter. They are not contagious, but a cold may spread among a group of children and cause some of them to get ear infections.

Risk Factors

Age (children between six and 18 months are most likely to get ear infections)
Attending daycare
Recent illness (such as a cold or sinus infection)
History of allergies (like hay fever, also called allergic rhinitis, or sinusitis)
Exposure to secondhand smoke
Having family members who are prone to ear infections
Using a pacifier

Diagnosis

The doctor will ask questions about whether you (or your child) have had ear infections in the past and ask you to describe the current symptoms. He or she will use an otoscope to look inside the ear. If infected, there may be areas of dullness or redness or there may be air bubbles or fluid behind the eardrum. The fluid may be bloody or filled with pus. The doctor will also check for any sign of perforation (hole or holes) in the eardrum.

Your doctor may also do other tests:

Tympanometry, which uses a small handheld instrument to measure changes in air pressure in the ear and can indicate if the eardrum is ruptured

Reflectometry, in which a small instrument is placed near the ear and makes a sound, allowing the doctor to see if fluid is present behind the eardrum.

A hearing test may be recommended if your child has had persistent ear infections.

Preventive Care

You can reduce your child's risk of ear infection. Here are some tips:

Don't expose your child to secondhand smoke.
Keep your child away from other children who are sick.
Always hold your infant in an upright, seated position during bottle feeding.
Breastfeeding for at least six months can make a child less prone to ear infections.
Don't use a pacifier.
The pneumococcal vaccine (Prevnar) prevents infections such as pneumonia and meningitis, and studies show it slightly reduces the risk of ear infections.

Treatment Approach

The goals for treating ear infections include curing the infection, relieving pain and other symptoms, and preventing future ear infections. If a bacterial infection is present, your doctor may prescribe antibiotics (see section entitled Medications).

However, most ear infections clear up on their own. Because antibiotics tend to be overused for treating ear infections, the Academy of Pediatricians and the American Academy of Family Physicians guidelines suggest taking a wait-and-see approach for 72 hours if

The child is older than six months
Are otherwise healthy
Have mild symptoms or an unclear diagnosis.

Your doctor may suggest using an over-the-counter pain reliever (see Medications). There are also alternative ways to treat the symptoms of ear infections and to prevent persistent and recurrent ear infections. For example, herbal ear drops and homeopathic remedies can be helpful for treating or preventing ear infections.

Before giving any medication to a child, whether over-the-counter, and herbal remedy, or a dietary supplement, you should talk to your pediatrician.

Lifestyle

Applying a warm, moist cloth over the affected ear may help relieve pain.

Medications

Antibiotics - If your doctor prescribes antibiotics, be sure to give your child the entire course. The antibiotic most often prescribed for an ear infection is amoxicillin, unless your child is allergic to penicillin. If that's the case. there are several others for your doctor to choose from.
Ear drops - If your child has recurring ear infections, a perforated eardrum, or develops infection after ear tubes have been placed (see Surgery and Other Procedures), your doctor may prescribe antibiotic ear drops instead of oral antibiotics, to be used over a period of time (like a few months). If your child doesn't have ear tubes in place and doesn't have any drainage from the ear, your doctor may also prescribe anesthetic ear drops to relieve pain.
Ibuprofen, acetaminophen - Ask your doctor about using over-the-counter oral medications for pain and/or fever, such as ibuprofen (Advil, Motrin) or acetaminophen (Tylenol). Children under 18 should not take aspirin, due to the risk of developing a rare but serious illness called Reye's syndrome.

Surgery and Other Procedures

Drainage tubes (myringotomy) - If your child has recurring ear infections that don't respond to antibiotics or if the fluid in the child's ear affects his hearing, your doctor may suggest putting in drainage tubes. During this surgery, which requires general anesthesia, the surgeon inserts a small drainage tube through the eardrum. Fluid behind the eardrum can drain out, equalizing the pressure between the middle and outer ear, which should improve your child's hearing. The tubes usually come out on their own as your child grows and the drainage holes heal.

If ear infections persist after age 4, your doctor may suggest having your child's adenoids (tonsils) removed.

Nutrition and Dietary Supplements

Because supplements (like those described below) may have side effects or interact with medications, they should be taken only under the supervision of a knowledgeable healthcare provider. If you think your child has an ear infection, you should always talk to your doctor - don't try to treat the child yourself.

Lactobacillus - A probiotic or "friendly" bacteria, it may help reduce the number of colds your child gets (and thus reduce the number of ear infections). One study found that children in daycare centers who drank milk fortified with Lactobacillus had fewer and less severe colds.
Xylitol – A sugar alcohol produced naturally in birch, strawberries, and raspberries, it may help fight a type of bacteria that's associated with ear infections. In one study, children who chewed sugarless gum sweetened with xylitol reduced their risk of developing and ear infection by more than a third. However, children in the study were given the gum five times a day, which makes it hard to be compliant. Another study found that taking xylitol three times per day didn't work. More research is needed.
Elimination diet - Some doctors believe food allergies contribute to chronic ear infections. Your doctor may ask you to try an elimination diet, which cuts out common food allergens such as wheat or dairy. If symptoms improve, you gradually add back the foods until an ear infection returns. Then you are able to identify and avoid the particular food.

Herbs

The use of herbs is a time-honored approach to strengthening the body and treating disease. Herbs, however, can trigger side effects and can interact with other herbs, supplements, or medications. For these reasons, herbs should be taken with care, under the supervision of a healthcare practitioner. Before giving any herbs to a child to treat an ear infection, talk to your pediatrician.

Herbal ear drops (Calendula officinalis, Hypericum perfoliatum, Verbascum thapsus, Allium sativum) - A few studies suggest that ear drops containing calendula, mullein, St. John's wort, and garlic were as effective at relieving pain as prescription ear drops. However, using oily ear drops can make it hard for the doctor to examine your child's middle ear, so always talk to your doctor first before using them.
Echinacea (Echinacea purpurea) - Although it has not been studied for ear infections, some doctors may suggest echinacea to help prevent recurring ear infections. Only give echinacea to a child under your doctor's supervision.
Belladonna (Atropa belladonna) - Belladonna is used as a homeopathic remedy for ear infections (see Homeopathy). Although herbal belladonna is toxic, it is safe when prescribed by a homeopath because homeopathic solutions use extremely diluted amounts. Do not use belladonna without the supervision of a trained homeopath.

Homeopathy

Although not many studies have examined the effectiveness of specific homeopathic therapies in general, there have been several studies evaluating homeopathy for ear infections. Some of the homeopathic remedies included in such studies or that a professional homeopath might consider for the treatment of ear infections are listed below. Before prescribing a remedy, homeopaths take into account a person's constitutional type. A constitutional type is defined as a person's physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate treatment for each individual.

Aconitum - for throbbing ear pain that comes on suddenly after exposure to cold or wind; and in children with high fever and whose ears have a bright red coloring
Belladonna - for sudden onset of infection with piercing pain that often spreads to the neck, flushed face including reddened ears, agitation (even impaired consciousness and nightmares), wide-eyed stare, high fever, and swollen glands; this remedy is most appropriate for children who feel relief when sitting upright and from warm compresses to the ear; this remedy should not be used in children whose symptoms have persisted for more than 3 days
Chamomilla - for intense ear pain and extreme irritability and anger (including screaming); this remedy is most appropriate for children who are difficult to comfort unless being rocked or carried by a person who is walking back and forth
Hepar Sulphuricum - for sharp pains and a smelly, yellowish-green discharge that occur in the middle and late stages of an ear infection, particularly when the child is extremely moody and clearly angry; this remedy is most appropriate for individuals whose symptoms are worsened by cold air and improved by warmth
Lycopedium - for right-side ear pain that is worse in the late afternoon and early evening; the child will generally say that his ears feel stuffed up and he may hear a ringing or buzzing sound; the appropriate individual tends to be insecure and need others around, although the personality type may act like a bully as a defense mechanism
Mercurius - good for chronic ear infections; for acute or chronic pain that is worse at night and may extend down into the throat; relief comes from nose blowing; and the appropriate child may sweat or drool a lot and have bad breath
Pulsatilla - for infection following exposure to cold or damp weather; the ear is often red and may have a yellowish/greenish discharge; ear pain worsens when sleeping in a warm bed and is relieved somewhat by cool compresses; this remedy is most appropriate for children who tend to be gentle, weepy, and mildly whiny and are easily soothed by affection
Silica - for chronic or late stage infection when the child feels chilly, weak and tired; sweating may also be present.

Other Considerations

Warnings and Precautions

If you think your child has an ear infection, especially if your child is under 2, call your pediatrician.

Let your doctor know if your child's symptoms (pain, fever, or irritability) do not get better within 24 to 48 hours.

If severe pain suddenly stops, it may indicate a ruptured eardrum.

Swimming and diving underwater may make an ear infection worse. If your child has a ruptured eardrum, he should avoid swimming or diving completely. If your child has ear tubes, use earplugs or cotton balls coated with petroleum jelly when swimming to prevent infection.

Prognosis and Complications

Generally, an ear infection is a simple, non-serious condition without complications. Most children will have minor, temporary hearing loss during and right after an ear infection. Permanent hearing loss is extremely rare, but the risk increases if the child has a lot of ear infections. Other potential complications include:

Ruptured or perforated eardrum (usually heals on its own)
Chronic, recurrent ear infections
Enlarged adenoids or tonsils
Mastoiditis (an infection of the bones around the skull)
Speech or language delay in a child who suffers lasting hearing loss from multiple, recurrent ear infections; very rare

Highlights

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.

Click the icon to see an illustrated series detailing ear tube insertion.

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.

Children and weight problems

Information

In the U.S., at least one out of five kids is overweight. The number of overweight children continues to grow. Over the last two decades, this number has increased by more than 50% and the number of "extremely" overweight children has nearly doubled.

A doctor determines if children are overweight by measuring their height and weight. Although children have fewer weight-related health problems than adults, overweight children are at high risk of becoming overweight adolescents and adults. Overweight adults are at risk for a number of health problems including heart disease, diabetes, high blood pressure stroke, and some forms of cancer.

Did You Know That...

Obese children and adolescents have shown an alarming increase in the incidence of type 2 diabetes, also known as adult-onset diabetes.
Many obese children have high cholesterol and blood pressure levels, which are risk factors for heart disease.
One of the most severe problems for obese children is sleep apnea (interrupted breathing while sleeping). In some cases this can lead to problems with learning and memory.
Obese children have a high incidence of orthopedic problems, liver disease, and asthma.
Overweight adolescents have a 70 percent chance of becoming overweight or obese adults.

Children become overweight for a variety of reasons. The most common causes are genetic factors, lack of physical activity, unhealthy eating patterns, or a combination of these factors. In rare cases, a medical problem, such as an endocrine disorder, may cause a child to become overweight. Your doctor can perform a careful physical exam and some blood tests, if necessary, to rule out this type of problem.

Genetic Factors: Children whose parents or brothers or sisters are overweight may be at an increased risk of becoming overweight themselves. Although weight problems run in families, not all children with a family history of obesity will be overweight. Genetic factors play a role in increasing the likelihood that a child will be overweight, but shared family behaviors such as eating and activity habits also influence body weight.
Lifestyle: A child's total diet and his or her activity level both play an important role in determining a child's weight. The increasing popularity of television and computer and video games contributes to children's inactive lifestyles. The average American child spends approximately 24 hours each week watching television-time that could be spent in some sort of physical activity.

TALK TO YOUR DOCTOR

If you think that your child is overweight, it is important to talk with your child's doctor. A doctor is the best person to determine whether your child has a weight problem. doctors will measure your child's weight and height to determine if your child's weight is within a healthy range. A doctor will also consider your child's age and growth patterns to determine whether your child is overweight. Assessing overweight in children is difficult because children grow in unpredictable spurts. Based on your child's height and weight, they will calculate a body mass index (BMI). If your child's BMI is greater than 95% of children their age and gender, they are considered to be overweight

For example, it is normal for boys to have a growth spurt in weight and catch up in height later. It is best to let your child's doctor determine whether your child will "grow into" a normal weight. If your doctor finds that your child is overweight, he or she may ask you to make some changes in your family's eating and activity habits.

BE SUPPORTIVE

One of the most important things you can do to help overweight children is to let them know that they are okay whatever their weight. Children's feelings about themselves often are based on their parents' feelings about them. If you accept your children at any weight, they will be more likely to accept and feel good about themselves. It is also important to talk to your children about weight, allowing them to share their concerns with you. Your child probably knows better than anyone else that he or she has a weight problem. For this reason, overweight children need support, acceptance, and encouragement from their parents.

FOCUS ON THE FAMILY

Parents should try not to set children apart because of their weight, but focus on gradually changing their family's physical activity and eating habits. Family involvement helps to teach everyone healthful habits and does not single out the overweight child.

INCREASE YOUR FAMILY'S PHYSICAL ACTIVITY

Regular physical activity, combined with healthy eating habits, is the most efficient and healthful way to control your weight. It is also an important part of a healthy lifestyle. Some simple ways to increase your family's physical activity include the following:

Be a role model for your children. If your children see that you are physically active and have fun, they are more likely to be active and stay active for the rest of their lives.
Plan family activities that provide everyone with exercise and enjoyment, like walking, dancing, biking, or swimming. For example, schedule a walk with your family after dinner instead of watching TV. Make sure that you plan activities that can be done in a safe environment.
Be sensitive to your child's needs. Overweight children may feel uncomfortable about participating in certain activities. It is important to help your child find physical activities that they enjoy and that aren't embarrassing or too difficult.
Reduce the amount of time you and your family spend in sedentary activities, such as watching TV or playing video games.
Become more active throughout your day and encourage your family to do so as well. For example, walk up the stairs instead of taking the elevator, or do some activity during a work or school break-get up and stretch or walk around.

The point is not to make physical activity an unwelcome chore, but to make the most of the opportunities you and your family have to be active.

TEACH YOUR FAMILY HEALTHY EATING HABITS

Teaching healthy eating practices early will help children approach eating with the right attitude-that food should be enjoyed and is necessary for growth, development, and for energy to keep the body running. The best way to begin is to learn more about children's nutritional needs by reading or talking with a health professional and then to offer them some healthy options, allowing your children to choose what and how much they eat.

DON'T PLACE YOUR CHILD ON A RESTRICTIVE DIET

Children should never be placed on a restrictive diet to lose weight, unless a doctor supervises one for medical reasons. Limiting what children eat may be harmful to their health and interfere with their growth and development.

To promote proper growth and development and prevent overweight, parents should offer the whole family a wide variety of foods from each of the food groups.

Most of the foods in your diet should come from the grain products group (6-11 servings), the vegetable group (3-5 servings), and the fruit group (2-4 servings). (See chart for suggested serving sizes.)
Your diet should include moderate amounts of foods from the milk group (2-3 servings) and the meat and beans group (2-3 servings).
Foods that provide few nutrients and are high in fat and sugars should be used sparingly. Fat should not be restricted in the diets of children younger than 2 years of age.

EXAMPLES OF ONE SERVING

Bread, cereal, rice, pasta

1 slice of bread
1 ounce of ready to eat cereal
1/2 cup of cooked cereal, rice, or pasta

Milk, yogurt, cheese

1 cup of milk or yogurt
1 1/2 ounces of natural cheese
2 ounces of processed cheese

Vegetables

1 cup of raw vegetables or 1/2 cup of frozen leafy leafy vegetables (cooked)
1/2 cup of other vegetables - cooked or chopped raw
3/4 cup of vegetable juice

Meat, poulty, fish, beans, nuts

2-3 ounces of cooked lean meat, poultry, or fish
1/2 cup of cooked dry beans or 1 egg counts as 1 ounce of lean meat
2 tablespoons of peanut butter or 1/3 cup of nuts count as 1 ounce of meat

Fruits

1 medium apple, banana, or orange
1/2 cup of chopped, cooked, or canned fruit
3/4 cup of fruit juice

Serving sizes are for children and adults ages 2 years and older. A range of servings is given for each food group. The smaller number is for children who consume about 1,300 calories a day, such as 2-4 years of age. The larger number is for those who consume about 3,000 calories a day, such as boys 15-18 years of age.

CUT DOWN ON FAT

Reducing fat is a good way to cut calories without depriving your child of nutrients. Simple ways to cut the fat in your family's diet include eating lowfat or nonfat dairy products, poultry without skin and lean meats, and lowfat or fat-free breads and cereals.

Making small changes to the amount of fat in your family's diet is a good way to prevent excess weight gain in children: however, major efforts to change your child's diet should be supervised by a health professional.

In addition, fat should not be restricted in the diets of children younger than 2 years of age. After that age, children should gradually adopt a diet that contains no more than 30 percent of calories from fat by the time the child is about 5 years old.

DON'T OVERLY RESTRICT SWEETS OR TREATS

While it is important to be aware of the fat, salt, and sugar content of the foods you serve, all foods -- even those that are high in fat or sugar -- have a place in the diet (in moderation, of course). However, children should be taught to limit high-calorie soft drinks and foods such as candy and deserts, and salty snacks such as potato chips and french fries.

GUIDE CHOICES RATHER THAN DICTATE FOODS

Make a wide variety of healthful foods available in the house. This practice will help your children learn how to make healthy food choices.

ENCOURAGE YOUR CHILD TO EAT SLOWLY

A child can detect hunger and fullness better when eating slowly.

EAT MEALS TOGETHER AS A FAMILY

Try to make mealtimes pleasant with conversation and sharing, not a time for scolding or arguing. If mealtimes are unpleasant, children may try to eat faster to leave the table as soon as possible. They then may learn to associate eating with stress.

INVOLVE CHILDREN IN FOOD SHOPPING AND PREPARING

These activities offer parents hints about children's food preferences, teach children about nutrition, and provide children with a feeling of accomplishment. In addition, children may be more willing to eat or try foods that they help prepare.

PLAN FOR SNACKS

Continuous snacking may lead to overeating, but snacks that are planned at specific times during the day can be part of a nutritious diet, without spoiling a child's appetite at mealtimes. You should make snacks as nutritious as possible, without depriving your child of occasional chips or cookies, especially at parties or other social events. Below are some ideas for healthy snacks.

EXAMPLES OF HEALTHY SNACKS

Fresh, frozen, or canned vegetables and fruit served either plain or with lowfat or fat-free cheese or yogurt
Dried fruit, served with nuts or sunflower or pumpkin seeds
Breads and crackers made with enriched flour and whole grains, served with fruit spread or fat-free cheese
Frozen desserts, such as nonfat or lowfat ice cream, frozen yogurt, fruit sorbet, popsicles, water ice, and fruit juice bars

Warning: Children of preschool age can easily choke on foods that are hard to chew, small and round, or sticky, such as hard vegetables, whole grapes, hard chunks of cheese, rasins, nuts, and seeds, and popcorn. It's important to carefully select snacks for children in this age group.

DISCOURAGE EATING WHILE WATCHING TV

Try to eat only in designated areas of your home, such as the dining room or kitchen. Eating in front of the TV may make it difficult to pay attention to feelings of fullness, and may lead to overeating.

DON'T USE FOOD TO PUNISH OR REWARD

Withholding food as a punishment may lead children to worry that they will not get enough food. For example, sending children to bed without any dinner may cause them to worry that they will go hungry. As a result, children may try to eat whenever they get a chance. Similarly, when foods, such as sweets, are used as a reward, children may assume that these foods are better or more valuable than other foods. For example, telling children that they will get dessert if they eat all of their vegetables sends the wrong message about vegetables.

MONITOR MEALS OUTSIDE THE HOME

Find out more about your school lunch program, or pack your child's lunch to include a variety of foods. Also, select healthier items when dining at restaurants.

SET A GOOD EXAMPLE

Children are good learners, and they learn best by example. Setting a good example for your kids by eating a variety of foods and being physically active will teach your children healthy lifestyle habits that they can follow for the rest of their lives.

ADDITIONAL HELP

If you need to make changes to your family's eating and exercise habits, but are finding it difficult, a registered dietitian (RD) may be able to help. Your doctor may be able to refer you to an RD, or you can call the National Center for Nutrition and Dietetics of The American Dietetic Association at 800-366-1655 and ask for the name of an RD in your area.

If your efforts at home are unsuccessful in helping your child reach a healthy weight and your doctor determines that your child's health is at risk unless he or she loses weight steadily, you may want to consider a formal treatment program. To locate a weight-control program for your child, you may want to contact a local university-based medical center.

Look for the following characteristics when choosing a weight-control program for your child. The program should:

Be staffed with a variety of health professionals. The best programs may include RDs, exercise physiologists, pediatricians or family doctors, and psychiatrists or psychologists.
Perform a medical evaluation of the child. Before being enrolled in a program, your child's weight, growth, and health should be reviewed by a doctor. During enrollment, your child's weight, growth, and health should be monitored by a health professional at regular intervals.
Focus on the whole family, not just the overweight child.
Be adapted to the specific age and capabilities of the child. Programs for 4-year-olds are different from those developed for children 8 or 12 years of age in terms of degree of responsibility of the child and parents.
Focus on behavioral changes.
Teach the child how to select a variety of foods in appropriate portions.
Encourage daily activity and limit sedentary activity, such as watching TV.
Include a maintenance program and other support and referral resources to reinforce the new behaviors and to deal with underlying issues that contributed to overweight.

The overall goal of a successful treatment program should be to help the whole family focus on making healthy changes to their eating and activity habits that they will be able to maintain throughout life.

Drug Warning

In 2007, the FDA requested the manufacturers of omalizumab (Xolair) to include a “boxed warning” emphasizing that this drug may cause a severe and life-threatening allergic reaction (anaphylaxis). Health care providers need to carefully observe patients for 2 hours after they receive an omalizumab injection. However, because an allergic reaction can occur up to 24 hours after the injection, patients need to know the signs and symptoms of anaphylaxis and how to self-administer emergency treatment. Omalizumab is approved for patients ages 12 and older who have moderate-to-severe asthma related to allergies.

Drug Approval

In 2006, budesonide/formoterol (Symbicort) was approved for patients age 12 years and older. Symbicort combines a corticosteroid and a long-acting beta2-agonist into a single inhaler.

Inhaled Corticosteroids

Inhaled corticosteroids may help reduce wheezing in young children with breathing problems, but they do not help prevent the development of asthma, according to several 2006 studies in the New England Journal of Medicine.
Inhaled corticosteroids work better than a corticosteroid/long-acting beta2-agonist combination or a leukotrine receptor antagonist drug in treating children with mild-to-moderate asthma, suggests a 2007 study in the Journal of Allergy and Clinical Immunology.

Long-Acting Beta2-Agonists

Long-acting beta2-agonist drugs such as salmeterol (Serevent Diskus) and formoterol (Foradil Aerolizer) may worsen asthma symptom severity and increase the risk for asthma-related death, indicates a 2006 review in the Annals of Internal Medicine.
Products that contain salmeterol and formoterol now have strengthened warning labels detailing these risks.

Childhood Asthma Statistics

Asthma death rates among children have largely declined since 1999 while doctors’ office visits for asthma treatment have more than doubled, indicates a recent report from the U.S. Centers for Disease Control and Prevention.

Introduction

The word asthma originates from an ancient Greek word meaning panting. Essentially, asthma is an inability to breathe properly. When any person inhales, the air travels through the following structures:

Air passes into the lungs and flows through progressively smaller airways called bronchioles. The lungs contain millions of these airways.
All bronchioles lead to alveoli, which are microscopic sacs where oxygen and carbon dioxide are exchanged.

The major features of the lungs include the bronchi, the bronchioles, and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.

Asthma is a chronic condition in which these airways undergo changes when stimulated by allergens or other environmental triggers. Such changes appear to be two specific responses:

The hyperreactive response (also called hyperresponsiveness)
The inflammatory response

These actions in the airway cause patients to cough, wheeze, and experience shortness of breath (dyspnea), the classic symptoms of asthma.

In the hyperreactive response, smooth muscles in the airways constrict and narrow excessively in response to inhaled allergens or other irritants. Airways in everyone's lungs respond by constricting when exposed to allergens or irritants but there are major differences in the hyperreactive response that occurs in people with asthma:

When people without asthma breathe in and out deeply, the airways relax and open in order to rid the lungs of the irritant.
When people with asthma try to take those same deep breaths, their airways do not relax but instead narrow, causing the patients to pant for breath. Smooth muscles in the airways of people with asthma may have a defect, perhaps a deficiency in a critical chemical that prevents the muscles from relaxing.

The hyperreactive stage is followed by the inflammatory response, which generally contributes to asthma in the following way:

The immune system responds to allergens or other environmental triggers by delivering white blood cells and other immune factors to the airways.
These so-called inflammatory factors cause the airways to swell, fill with fluid, and produce a thick sticky mucus.

Click the icon to see an image of a normal versus asthmatic bronchiole.

This combination of events results in wheezing, breathlessness, inability to exhale properly, and a phlegm-producing cough.

Inflammation appears to be present in the lungs of all patients with asthma, even those with mild cases, and plays a key role in all forms of the disease.

Causes

Asthma occurs in about 5 million American children. Each year about 200,000 of them are hospitalized. It is the most common chronic childhood illness. About half of all cases of asthma develop before the age of 10, and about 80% of patients develop symptoms before they are 5 years old.

The mechanisms that cause asthma are complex and vary among population groups and even individuals. For example, asthma in children is highly associated with allergies. However, only a minority of children with allergies have asthma, and allergic response cannot explain all cases of asthma. Other factors, such as genetics or environmental conditions are probably involved in the development of asthma. Most likely, several genes combine to make a child susceptible to environmental triggers, not only allergens but also possibly infections, dietary patterns, or air pollution. Physical factors, particularly having smaller lungs, affect the chances for later asthma.

Asthma and allergies often coexist, and the allergic response plays a strong role in childhood asthma. About 70 - 85% of children with asthma also have allergies. Some studies suggest that children who have allergies are also at greater risk for developing asthma as adults. A 2006 study found that children who are allergic to dust mites are three times more likely to later develop asthma than children who were not allergic.

However, the evidence is clearly mixed. Several other 2006 studies suggested that avoiding dust mites does not help prevent asthma and, in fact, early exposure to dust mites may even protect children from developing asthma and allergic responses. Some experts think that giving immunotherapy (“allergy shots”) to children with allergies may help prevent asthma development.

An asthma attack can be induced or aggravated by direct irritants to the lungs. Studies indicate that the more indoor allergens a child is allergic to, the higher the risk for severe asthma. Important irritants or allergens include the following:

Dust mites, specifically mite feces, which are coated with enzymes that contain a powerful allergen. These are the primary allergens in the home.
Animal dander. Cats harbor significant allergens, which can even be carried on clothing; dogs usually present fewer problems.
Molds.
Cockroaches. Cockroaches are major asthma triggers and may reduce lung function even in people without a history of asthma.
Pollen. An asthma attack from an allergic response to pollen is more likely to occur during extreme air changes, such as thunderstorms. Major weather changes, such as El Nino, can affect the timing of allergy seasons because they cause seasonal changes (and pollen) to start earlier.
Food allergies. About 8 - 10% of children with asthma also have food allergies. These children also appear to have a high risk for very serious reactions to such foods. In infants and toddlers, allergy to eggs appears to be a predictor of asthma.
Fossil Fuels. Certain chemicals may trigger allergic rhinitis. Some experts believe that refined fossil fuels, such as diesel fuel and particularly kerosene, may be important triggers for allergic rhinitis. In people who already have allergies or asthma, exposure to such fossil fuels may worsen symptoms.

The Allergic Response. The allergic process, called atopy, and its connection to asthma are not completely understood. It involves various airborne allergens or other triggers that set off a cascade of events in the immune system leading to inflammation and hyperreactivity in the airways. One description is as follows:

The conductor in an orchestra of immune factors that contribute to allergies and asthma appears to be a category of white blood cells known as helper T cells, in particular a subgroup called Th2 cells.
Th2 cells overproduce interleukins (ILs), immune factors that are molecular members of a family called cytokines, which are involved in the inflammatory process.
Interleukins 4, 9, and 13, for example, may be responsible for a first-phase asthma attack. These interleukins stimulate the production and release of antibody groups known as immunoglobulin E (IgE). (People with both asthma and allergies appear to have a genetic predisposition for overproducing IgE.)
During an allergic attack, these IgE antibodies can bind to special cells in the immune system called mast cells, which are generally concentrated in the lungs, skin, and mucous membranes. This bond triggers the release of a number of active chemicals, importantly potent molecules known as leukotrienes. These chemicals cause airway spasms, overproduce mucus, and activate nerve endings in the airway lining.
Another cytokine, interleukin 5, appears to contribute to a late-phase inflammatory response. This interleukin attracts white blood cells known as eosinophils. These cells accumulate and remain in the airways after the first attack. They persist for weeks and mediate the release of other damaging particles that remain in the airways.

Researchers are investigating the role that T cells play in asthma. T cells are white blood cells that are involved in the immune response. Researchers had focused on the T cell called type 2 helper (ThH2) cells. However, a 2006 breakthrough study in the New England Journal of Medicine suggested that a different type of T cell may play a stronger role in asthma than previously thought.

Researchers discovered that these cells, called natural killer T cells, are far more common in the lungs of people with asthma than in the lungs of healthy people. Natural killer T cells are very rare, but researchers found them in 60% of people with moderate-to-severe persistent asthma. While this research is preliminary, it may explain why corticosteroid drugs do not work well for some patients with asthma: Steroid drugs target Th2 and other inflammatory cells, not natural killer T cells. Researchers think that further investigation of natural killer T cells may lead the way to new types of asthma drugs. If these cells prove to be involved in asthma, then drugs that eliminate them might become an important new treatment.

Over the course of years the repetition of the inflammatory events involved in asthma can cause irreversible structural and functional changes in the airways, a process called remodeling. The remodeled airways are persistently narrow and can cause chronic asthma. Researchers are trying to determine how this process occurs:

Interleukins. Some researchers are looking at potent immune factors, including interleukins 11 and 13. They have been linked to a number of processes possibly involved in remodeling, including scarring in the airways and overgrowth of cells in the smooth muscles that line the airways.

Growth Factors. Compounds known as vascular endothelial growth factor (VEGF) have been observed in the airways of patients with asthma. VEGF is a powerful promoter of cell growth in blood vessel linings and some researchers believe it may be major factor in remodeling.

About one-third of all persons with asthma share this condition with another member of their immediate family. Asthma may be more likely to be passed to children from the mother than from the father. Both allergies and asthma are strongly associated with hereditary factors, sharing certain genetic markers, but they are not always inherited together.

Research on the genetics of these conditions is confusing. Of some significant promise, researchers have identified a gene (ADAM33), which has been linked to asthma. The gene regulates one of the enzymes called metalloproteases, which are involved with the smooth muscle in the airway. A mutation of this gene could play a role in airway changes that occur after inflammation.

The role of early childhood respiratory and intestinal infections is very complex. Viral respiratory infections certainly worsen existing asthma, but the most common ones are unlikely to be causes of childhood asthma. In fact, early respiratory and intestinal infections may offer some protection against asthma.

Early Respiratory Infections as Causes of Asthma. Studies suggest that most respiratory infections are not important causes of asthma in children, except in certain cases. An important exception is the respiratory syncytial virus (RSV), which has been implicated in the development of asthma. RSV is the major viral cause of infant pneumonia. Studies also indicate that infants who have reduced lung function within a few days after birth are at increased risk of developing asthma by the time they are 10 years old.

Common Respiratory Infections Worsen Asthma. Common respiratory infections viruses that cause colds (such as the rhinovirus) may in some cases be associated with the development of asthma. A 2007 study suggested that children who have a wheezing rhinovirus during infancy are at increased risk for developing asthma by age 6. Even if these viruses do not directly cause asthma, they can worsen asthma in children who already have it. Rhinovirus has been reported to be the most common infection associated with asthma attacks. In one study, it was associated with 61% of asthma worsening in children. Some research suggests that colds promote inflammation in patients with existing asthma and increase the intensity of airway responsiveness for weeks.

The Hygiene Theory: Early Infections as Protection Against Asthma. Another blames the dramatic increase in asthma on the reductions in childhood infections that have occurred with modern hygiene and antibiotic use. The basic theory rests on the idea that infections stimulate production of specific immune factors called Th1 cells. As these cells build up, they replace other immune factors called Th2 cells, which react to allergens -- a less serious threat to the body. Without infections to stimulate the production of the Th1 infection fighters, the Th2 allergen fighters are not replaced, and they persist at high levels, making the growing child more susceptible to allergies and asthma.

A number of different studies support this theory:

Some studies suggest that being part of a large family or attending day care increases the risk for early respiratory infections but reduces the risk of childhood asthma. The occasional cold, then, may be protective.
In one study, researchers measured levels of bacterial byproducts called endotoxins in the mattress dust of 812 children. Those with the highest levels had 80% lower rates in allergies and asthma.
Another study further found a strong association between allergy development and the absence of certain beneficial bacteria (called probiotics) carried in the infant's intestines. Infants who were born in more hygienic environments tended to lack these bacteria. Antibiotic overuse and modern hygiene may be reducing these helpful organisms. (Probiotics can be obtained in active yogurt cultures and in supplements, which are being studied for protection.)

The standard vaccinations against serious childhood infections, according to several important studies, pose no risk for asthma. One of the studies even reported some lower risk for asthma and allergies in the second and third years after vaccinations. Infections killed thousands of children every year before immunization became widespread. Asthma, although serious, is rarely fatal in children. No one should stop giving their children vaccinations against childhood killers.

GERD. At least half of patients with asthma also have gastroesophageal reflux disease (GERD), the cause of heartburn. It is not entirely clear which condition causes the other or whether they are both due to common factors.

Heartburn is a condition where the acidic stomach contents back up into the esophagus causing pain in the chest area. This reflux usually occurs because the sphincter muscle between the esophagus and stomach is weakened. Standing or sitting after a meal can help reduce the reflux which causes heartburn. Continuous irritation of the esophagus lining as in gastroesophageal reflux disease is a risk factor for the development of adenocarcinoma.

Some theories for the causal connection between GERD and asthma are:

Acid leaking from the lower esophagus in GERD stimulates the vagus nerve, which runs through the gastrointestinal tract. This stimulated nerve, in turn, triggers the nearby airways in the lung to constrict, causing asthma symptoms.
Acid back-up that reaches the mouth may be inhaled into the airways (aspirated). Here, the acid triggers a reaction in the airways that cause asthma symptoms.

GERD is sometimes hard to detect and might be suspected as a contributor in the following patients:

Those who do not respond to asthma treatments.
Those whose asthma attacks follow episodes of heartburn.
Those whose attacks are worse after eating or exercise.
Those whose coughs follow episodes of acid reflux. (One study found that GERD was associated with about half of the episodes of coughs and wheezes in patients with asthma.)

Treating GERD symptoms with anti-acid drugs may resolve asthma in some (but not all) patients who share both conditions. A small 2005 observational study found that while GERD was common in patients with asthma, treatment of GERD had no effect on asthma symptoms. [See In-Depth Report #85: Heartburn and gastroesophageal reflux disease.]

Sinusitis. Almost half of children and adults with allergic asthma have sinus abnormalities, and in various studies, between 17 - 30% of patients with asthma develop true sinusitis. The presence of sinusitis, however, does not appear to increase the severity of asthma.

Parental Migraines and Childhood Asthma. Some studies have reported a link between childhood asthma and parental migraines, with one small study suggesting that children are about five times more likely to develop asthma if their parents have a history of migraines.

Exercise-induced asthma (EIA) is a limited form of asthma in which exercise triggers coughing, wheezing, or shortness of breath.

About 10% of adults and some fewer children have aspirin-induced asthma (AIA). With this condition, asthma gets worse when patients take aspirin. Aspirin is one of the drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). Although aspirin is used to reduce inflammation in other disorders, it appears to have the opposite effect in many asthma cases. It is not wholly known why this occurs. AIA often develops after a viral infection. It is a particularly severe asthmatic condition and is associated with up to 25% of asthma-related hospitalizations. In about 5% of cases, aspirin is responsible for a syndrome that involves multiple attacks of asthma, sinusitis, and nasal congestion. Such patients also often have polyps (small benign growths) in the nasal passages.

Patients with aspirin-induced asthma (AIA) should avoid aspirin and most likely NSAIDs, including ibuprofen (Advil) and naproxen (Aleve).

Acetaminophen (Tylenol) has been the traditional alternative for relief of minor pain for patients who are aspirin-sensitive. Unfortunately, recent evidence has muddied these recommendations. Moreover, some asthmatic episodes have been linked to high consumption of acetaminophen among adults. And a study of children with asthma reported that those who took ibuprofen were less likely to be hospitalized for asthma than those taking acetaminophen. This is of particular concern, since acetaminophen is the pain reliever of choice in small children.

Asthma occurs primarily at night (nocturnal asthma) in as many as 75% of patients with the condition. Attacks often occur between 2 - 4 a.m. Factors that might play role in nocturnal asthma may include one or more of the following:

Chemical and temperature changes in the body during the night that increase inflammation and narrowing of the airways
Delayed allergic responses from exposure to allergens during the day
The wearing off of inhaled medications toward the early morning
An increase in acid reflux (back up of stomach acid) that causes airways to narrow
Postnasal drip that occurs during sleep
Conditions relating to sleep, such as sleep apnea or sleeping on one's back, which may worsen any asthma attack that occurs at night

Some experts believe that nocturnal asthma may actually be a unique form of asthma with its own specific biologic mechanisms that occur only at night and which reduce natural steroid hormones (which block inflammation).

Exercise-induced asthma (EIA) is a limited form of asthma in which exercise triggers coughing, wheezing, or shortness of breath. This condition generally occurs in children and young adults, most often during intense exercise in cold dry air. Symptoms are generally most intense about 10 minutes after exercising and then gradually resolve.

EIA is triggered only by exercise and is distinct from ordinary allergic asthma in that it does not produce a long duration of airway activity, as allergic asthma does. (However, some people have both forms of asthma.) People who have only EIA do not appear to require long-term maintenance therapy. A study of military recruits with EIA also reported that the condition does not hinder a person's overall physical performance.

Medications. Cromolyn, a mild anti-inflammatory drug, or short-acting beta2-agonists have been the treatments of choice for preventing EIA. Newer approaches for people who work out regularly include pretreatment with long-acting beta2-agonists, such as salmeterol (Serevent) or the regular use of inhaled corticosteroids.

Hints for Reducing EIA. EIA occurs only after exercise and is more likely to occur with regular paced activities in cold, dry air. The following are some suggestions for reducing its impact:

Warm-up and cool-down periods are important.
Patients with EIA might do better with activities that involve short bursts of exercise (tennis, football) than with exercises involving long-duration regular pacing (cycling, soccer, and distance running).
Breathing through a scarf or through the nose helps warm up the airways.
Restricting dietary salt might help reduce EIA.

Prognosis

Asthma is the third major cause of hospitalization in children under age 15. The condition can be very serious in children, particularly those younger than age 5, because their airways are very narrow.

The severity of asthma is graded as mild intermittent and mild, moderate, and severe persistent. A patient in any of these categories, even mild intermittent, can still experience a severe and even life-threatening attack. According to one report, 30% of asthma deaths occur in patients with mild asthma.

Asthma is rarely fatal in children, with only 187 asthma deaths reported in 2002 in children under age 18. In fact, a 2006 study from the U.S. Centers for Disease Control and Prevention reported that asthma death rates for children have steadily declined since 1999. (During the same time, the number of doctor visits for asthma treatment more than doubled.) Even low mortality numbers are unacceptable, however, since asthma deaths are largely preventable.

Factors associated with an increased risk of death from asthma in children include:

Previous life-threatening episodes of asthma
Lack of adequate and ongoing health care. (Most likely the reason for the higher fatalities rates in minority children.)
Significant behavioral problems
Underestimating the severity of an acute attack poses the greatest threat. Unfortunately, one study of children found that nearly 40% of them were unaware of asthmatic symptoms when they occurred.

African American children have more than six times the death rate of Caucasians in the age groups of 4 years and younger and 15 - 24 years. Hispanic children also have a higher risk.

The following signs and symptoms may indicate a life-threatening situation:

As the chest labors to bring enough air into the lungs, breathing often becomes shallow.
Lacking sufficient oxygen, the skin becomes bluish.
The flesh around the ribs of the chest appears to be sucked in.
The patient may begin to lose consciousness.

Asthma often progresses very slowly to a serious condition or may develop to a fatal or near-fatal attack within a few minutes. It is very difficult to predict when an attack will become very serious. Early symptoms or lack thereof do not always reflect the ultimate severity of an attack. Some studies even suggest that people at high risk for fatal or near-fatal asthma attacks are those with poor awareness of their own reduced ability to breathe and who are slow in seeking help. Monitoring peak flow rates is, therefore, an important management component, since it provides a more accurate assessment of lung function than symptoms alone.

In a 2003 study, researchers followed people with asthma for longer than 30 years. About a third of children had outgrown their asthma in adulthood. In general, the more severe the childhood asthma, the greater the likelihood that it will persist. For example, only 23% of children who experienced wheezy bronchitis (wheezing during respiratory infections) suffered from frequent or persistent asthma in adulthood.

There is evidence that severe asthma can cause long-lasting damage and possibly permanent scarring in some patients. The risk for such injury is highest, however, when asthma strikes children in the first 3 - 5 years. There does not appear to be any significant risk for long-term lung damage for children who develop mild-to-moderate persistent asthma between ages 5 - 12. Children adapt well to living with asthma, and even with severe asthma they can function as well as healthy children in virtually all areas of life.

Studies are mixed over the effects of emotional disorders on the severity of asthma. One study indicated that parents of children with asthma may suffer greater psychological stress than their children. A 2000 study reported that mild-to-moderate asthma does not significantly affect the psychological well-being of most children ages 5 - 12. Teenagers and preteens may have particular difficulty coping with what they perceive as the social stigma of asthma. Parents and older children should not hesitate to seek help from support groups, doctors, friends, or family members. Support programs may help children to better manage their asthma and even reduce hospitalization.

Although there have been few studies on the effects of asthma on schooling, a 2000 study reported that nocturnal (nighttime) asthma affected school attendance and performance in children and work attendance in their parents.

Risk Factors

Asthma affects about 5 million American children between the ages of 5 - 14. Asthma has dramatically increased worldwide over the last few decades, in both developed and developing countries. From 1980 - 1994, asthma increased 160% in American children younger than 4 years and has also dramatically risen worldwide. Experts are puzzling over the cause of this phenomenon. Possible causes and risk factors that are suspects in the dramatic rise in asthma in children include:

Survival rates are now higher in low-birth-weight babies, who may be more susceptible to asthma.
Declining rates in nursing may be a contributor. Breast milk contains important anti-inflammatory substances, such as omega-3 fatty acids, which might protect against asthma.
Western dietary habits (which commonly include more fast foods and less fruits, vegetables, fiber, minerals, and other nutrients) may contribute to the development of childhood asthma.
Children are spending more time indoors watching television, playing video games, or using the computer and are, therefore, overexposed to indoor allergens.
The trend of making homes more energy-efficient may result in dust mites being trapped inside them.

Among younger children, asthma develops twice as frequently in boys as in girls, but after puberty it may be more common in girls.

Urban Life. Urban life is strongly associated with a higher risk. Although poverty plays a significant role, urban life has been associated with a higher risk for asthma in any income group and among both children and adults. In some urban areas, as many as 25% of children have asthma or show signs of wheezing. In fact, it may be greatly underdiagnosed in city children. A 1999 study reported that almost a third of children in inner-city kindergartens had asthma symptoms without a diagnosis of the disorder; 10% had actually been diagnosed with asthma, mainly because their symptoms were severe.

Ethnicity. Since 1980, asthma rates have risen the most dramatically among African American children, and they have significantly higher rates of asthma than Caucasian children. Hispanic children are also at higher risk. Both groups of minority children are more likely to have fatal asthma than Caucasian children.

Some studies indicate that the difference in risk exists simply because African Americans and other minority groups are more likely to live in urban areas. Poverty and lack of access to health care also play a role. However, Caucasian children who live in cities also face a high risk for asthma, and rural African American children do not.

Urban life and socioeconomic factors, however, may not fully explain the ethnic disparity.

Low Birth Weight. Infants of low birth weight are at higher risk for lung problems and asthma.

Winter Birth. Children born in the winter may have a greater risk for asthmatic allergies to cockroaches than children born at other times of the year.

Vitamin D. A 2006 study suggested a link between vitamin D intake during pregnancy and development of early childhood asthma. Pregnant women who had a higher intake of vitamin D were less likely to give birth to children who developed asthma.

Breast Feeding. Most studies on breastfeeding report some protection against wheezing and asthma in the first year of life. Breastfeeding has many other benefits for the child as well. The American Academy of Pediatrics recommends exclusively breastfeeding for the child's first 6 months of life.

Complications of Pregnancy. According to a 2000 study, complications of pregnancy, specifically those involving the mother's uterus (such as post-birth hemorrhage, pre-term contractions, insufficient placenta, and restricted growth of the uterus), are associated with an increased risk of childhood asthma. Another study reported that delivery procedures such as Cesarean section, the use of vacuum extraction or forceps also raised the risk of childhood asthma.

In both adults and children, the incidence of obesity and asthma has been increasing over recent years. Studies report a strong association between the two conditions. Some experts suggest that excess weight pressing on the lungs may trigger the hyperreactive response in the airways typical of asthma. Others believe that asthma leads to obesity by inhibiting physical activity, although several studies have found no difference in activity levels between people with or without asthma. Some studies suggest that many obese people may be misdiagnosed as having asthma when they are simply short of breath, possibly because of the increased effort required for breathing.

In any case, there is evidence that losing weight can relieve asthma symptoms. Some evidence also suggests that people who are overweight (body mass index greater than 25) have more difficulty getting their asthma under control. Weight loss in anyone who is obese and has asthma or shortness of breath reduces airway obstruction and improves lung function. [See In-Depth Report #53: Weight control and diet.].

Damp Homes. Studies suggest that children who live in damp homes have a much higher risk for asthma.

Mental Health. Research indicates that poor mental health of parents and children are significant predictors of more severe symptoms in childhood asthma. A 2000 study suggested that high stress levels can predict the onset and severity of asthma in children genetically at risk for the condition.

Symptoms

In children with asthmatic symptoms, it is important to first consider as a possible cause inhaled foreign objects such as peanuts; viral infections such as croup; and bacterial infections, which may be accompanied by high fever and progress rapidly. Any child who has frequent coughing or respiratory infections should be checked for asthma.

The classic symptoms of an asthma attack include:

Wheezing when breathing out is nearly always present during an attack. Usually the attack begins with wheezing and rapid breathing, and, as it becomes more severe, all breathing muscles become visibly active.
Shortness of breath (dyspnea). Shortness of breath is a major source of distress in patients with asthma, although severe dyspnea does not always reflect a serious attack or reduced lung function.
Coughing. In some people, the first symptom of asthma is a nonproductive cough.
Chest tightness or pain. Initial chest tightness without any other symptoms may be an early indicator of a serious attack.
Neck muscles may tighten, and talking may become difficult or impossible.
Rapid heart rate
Sweating
Chest pain occurs in about 75% of patients. It can be very severe, although its intensity is not necessarily related to the severity of the asthma attack itself.

The end of an attack is often marked by a cough that produces thick, stringy mucus. After an initial acute attack, inflammation persists for days to weeks, often without symptoms. (The inflammation itself must still be treated, however, because it usually causes relapse.)

Diagnosis

The doctor will consider a diagnosis of asthma if a child has a history of periodic attacks of shortness of breath, coughing, and wheezing, perhaps accompanied by tightness in the chest. The parent should describe the pattern of symptoms and possible precipitating factors, including:

Whether symptoms are more frequent during the spring or fall (allergy seasons)
Whether exercise, a respiratory infection, or exposure to cold air has ever triggered an attack
Any family history of asthma or allergic disorders such as eczema, hives, or hay fever

A number of disorders may cause some or all of the symptoms of asthma. Panic disorder can coincide with asthma or be confused with it. Other diseases that must be considered during diagnosis are pneumonia, bronchitis, severe allergic reactions, psychosomatic illnesses, and certain rare disorders (such as tapeworm and trichomoniasis).

If symptoms and a patient's history are indicative of asthma, the doctor will usually perform tests known as pulmonary function tests to confirm the diagnosis and determine the severity of the disease.

Using a spirometer, an instrument that measures the air taken into and exhaled from the lungs, the doctor will determine several values:

Vital capacity (VC), which is the maximum volume of air that can be inhaled or exhaled.
Peak expiratory flow rate (PEFR), commonly called the peak flow rate, which is the maximum flow rate that can be generated during a forced exhalation.
Forced expiratory volume (FEV1), the maximum volume of air expired in 1 second.

If the airways are obstructed, these measurements will fall. Depending on the results, the doctor will take the following steps:

If measurements fall, the doctor typically asks the patient to inhale a bronchodilator. This drug is used in asthma to open the air passages. The measurements are taken again. If the measurements are more normal, the drug has most likely cleared the airways, and a diagnosis of asthma is strongly suspected.
If measurement results fail to show airway obstruction, but asthma is still suspected, the doctor may perform a challenge test. It involves administering a specific drug (histamine or methacholine) that usually increases airway resistance only when asthma is present.

The patient may be given skin or blood allergy tests, particularly if a specific allergen is suspected and available for testing. Allergy skin tests may be the best predictive test for allergic asthma, although they are not recommended for people with year-round asthma.

One of the most common methods of allergy testing is the scratch test or skin prick test. The test involves placing a small amount of the suspected allergy-causing substance (allergen) on the skin (usually the forearm, upper arm, or the back), and then scratching or pricking the skin so that the allergen is introduced under the skin surface. The skin is observed closely for signs of a reaction, which usually includes swelling and redness of the site. With this test, several suspected allergens can be tested at the same time, and results are usually available within about 20 minutes.

Tests that either rule out other diseases or obtain more information about the causes of asthma include the following:

A complete blood count
Chest and sinus x-rays
Computed tomography (CT) scans. CT scans may be helpful in certain cases, such as for determining wall thickness in airways in patients who are difficult to treat, which could signify a higher risk for lung damage.
Examination of the patient's sputum for eosinophils (white blood cells that in high levels are associated with severe allergic asthma).
Researchers are investigating measurements of certain chemicals in sputum or exhaled air that indicate airway inflammation. Such chemical markers include nitric oxide and hydrogen peroxide. For example, high levels of nitric oxide may prove to be a simple and noninvasive way of diagnosing asthma.

Treatment

Treating an Acute Attack in the Hospital. An acute attack may require hospitalization. Laboratory tests, an electrocardiogram (ECG), and a chest x-ray are performed to determine lung function, oxygen levels, and other indications of severity or rule out other causes. Depending on the results, the following treatments may be given:

Beta2-agonists are the standard therapy. They are typically administered with a nebulizer (a device that administers the drug in a fine spray). Studies suggest, however, that even very small children may be able to use metered-dose inhalers (MDIs), which are just as effective and more convenient than nebulizers. (Intravenous delivery is not recommended in most cases.)
An anticholinergic drug (ipratropium) is sometimes added to improve symptoms.
A corticosteroid (commonly called a steroid) given within the first hour helps reduce the need for hospitalization. Steroids may be administered intravenously, as a shot, or orally. Children may respond well to oral steroids.
Oxygen is usually administered, and can be life saving in severe cases.
Infusions of magnesium sulfate open airways and are an important emergency treatment for adults. Its benefits for children need to be further demonstrated.
In life-threatening situations, the patient may require mechanical ventilation.

Antibiotics are not useful for asthma attacks if there is no strong evidence of the presence of a bacterial infection. Viral infections, most often colds and the flu, are more likely to trigger an asthma attack. In such cases, antibiotics are not helpful and may have adverse effects.

Discharge and Relapse After Hospitalization. It typically takes about 3 - 4 hours to determine if a patient can be safely sent home or if they need to stay. Patients are generally discharged when:

Symptoms are gone or minimal, and
The peak expiratory flow rate is 70% or more of the predicted rate

Despite reasonable precautions, between 12 - 16% of patients relapse within 2 weeks of leaving the hospital. Receiving a steroid shot at discharge or taking an oral corticosteroid for a few days can reduce this risk.

Avoiding allergens, following appropriate drug treatments, and home monitoring are key elements in preventing dangerous asthma attacks and hospitalization. In addition, good communication between the doctor and patient is a key factor in a successful management program.

Medications for asthma fall into two categories:

Rescue Medications. Medications that open the airways (bronchodilators, or inhalers) are used to quickly relieve any moderate or severe asthma attack. These drugs are usually short-acting beta-adrenergic agonists (beta2-agonists). Other drugs used in special cases include corticosteroids taken by mouth and anticholinergic drugs. None of these drugs have any effect on the disease process itself. They are only useful for treating symptoms.
Maintenance Medications. Simply coping with asthma symptoms without also controlling the damaging inflammatory response is a common and serious error. For adults and children over age 5 with moderate-to-severe persistent asthma, experts now recommend inhaled corticosteroids and long-acting beta2-agonists.

Parents can greatly reduce the frequency and severity of their children’s asthma attacks by understanding the difference between coping with asthma attacks and controlling the disease over time. Unfortunately, many patients do not understand the difference between medications that provide rapid, short-term relief and those that are used for long-term symptom control. Many patients with moderate or severe asthma overuse their short-term medications and underuse their corticosteroid medications. The overuse of bronchodilators can have serious consequences; not using steroids can lead to permanent lung damage.

Patients need to understand that asthma symptoms can change quickly over time and that treatment strategies may need to change in response. In 2005, the two leading U.S. allergy associations published joint guidelines on controlling asthma. The guidelines emphasize that asthma treatment decisions need to be made on an individual basis. It is important that patients have a close relationship with their doctor. The doctor needs to evaluate a patient’s asthma symptoms at each visit to determine any need for changes in medication. According to the guidelines, asthma management is classified as either “well-controlled” or “not well-controlled.” The doctor may need to change some medications, or increase or decrease the dosage, depending on whether a child’s asthma is well-controlled or not well-controlled.

These are the signs of well-controlled asthma:

Asthma symptoms occur twice a week or less
Rescue bronchodilator medication is used twice a week or less
Symptoms do not cause nighttime or early morning awakening
Symptoms do not limit work, school, or exercise activities
Peak flow meter readings are normal or the patient’s personal best
Both the doctor and the patient consider the asthma to be well controlled

Adapted from National Asthma Education and Prevention Program (NAEPP) Expert Panel Report: Guidelines for the Diagnosis and Management of Asthma – Update on Selected Topics 2002 (EPR-2 Update).

Most asthma drugs are inhaled using various forms of inhalers or nebulizers. Inhaled drugs must be used regularly as prescribed and the patient carefully trained in their use in order for them to be effective and safe. Studies suggest that many children fail to use the devices properly, although newer devices are easier to use than others. The basic devices are the metered-dose inhaler (MDI), breath-actuated inhalers, dry powder inhalers, and nebulizers.

MDIs have used chlorofluorocarbons (CFCs) as their propellants. CFCs are damaging to the environment and are now being replaced with other propellants (hydrofluoroalkane) that are more environmentally safe, and do not chill the device as CFCs do. Devices that don't use any propellants are also now available.

Metered-Dose Inhaler. The standard device for administering any asthma medication is the metered-dose inhaler (MDI). This device, particularly when used with a spacer, allows precise doses to be delivered directly to the lungs. (The spacer is a tube that is attached to the inhaler. It serves as a holding chamber for the medication that is sprayed by the inhaler.) MDI-delivered drugs must be used regularly as prescribed and the patient carefully trained in their use in order for them to be effective and safe. Some patients hold the MDI too close to their mouths, or even inside them. Others may exhale too forcefully before inhalation.

The spacer helps improve medication delivery by allowing the patient additional time to inhale. They vary, however, in their effectiveness. It should be noted that MDIs can continue to deliver propellant even after the drug has been used up. Patients should track their medicine and throw the device away when the last dose has been administered.

Nebulizers (not MDIs) are typically used in very small children, both at home and in the emergency room. However, recent studies suggest spacers may be better than nebulizers for children and shorten the time spent in emergency rooms. Studies also indicate that with the use of a face mask and a spacer, the MDI works well even for infants in the emergency room and may prove to be useable at home.

Click the icon to see an illustrated series detailing a metered dose inhaler.

Breath-Actuated Inhalers. Breath-actuated rotary inhalers (Easi-Breathe and Autohaler) deliver the drug directly to the back of the throat as the user inhales. Their primary advantage over the MDI is their ease of use. They also do not use CFCs as propellants. In comparison studies, patients have been very successful with the breath-actuated inhalers. They are not recommended for children under 8 years old.

Dry Powder Inhalers. Dry powder inhalers (DPIs) deliver a powdered form of beta2-agonists or corticosteroids directly into the lungs. Such devices include Rotahaler, Spinhaler, Turbohaler, Clickhaler, Easyhaler, Diskhaler, Discus, Twisthaler, Spiros, and others. DPIs are as effective as the older devices, and generally have a better taste and are easier to manage. They may differ among themselves, however, in their ability to deliver drugs into the airways. In one study, for example, the Turbohaler was easier to use than the Diskhaler and so achieved better delivery.

Humidity or extreme temperatures can affect DPIs' performance, so they should not be stored in humid places (bathroom cabinets) or locations subject to high temperatures (glove compartments during summer months).

Dry-powder may cause tooth erosion. Children are advised to rinse their mouths out right after using these inhalers and to brush twice a day with a fluoride toothpaste.

Other Hand-Held Inhalers. Respimat delivers a fine-mist spray that is created by forcing the liquid medication through nozzles. It does not use any propellant.

Nebulizers. A nebulizer is a machine that delivers a fine spray of medication-containing liquid. Nebulizers are often used for children younger than 3 years and sometimes for older children who have difficulty using the MDI. It takes 5 - 10 minutes to administer medication using a nebulizer. Because the spray is less targeted than with the inhaler, it must deliver large amounts of the drug. This increases the risk for toxicity and severe side effects. Nebulizers should not be used by children who can manage an inhaler. Their use has been associated with a higher rate of hospitalizations and longer duration of symptoms than inhalers. A 2007 study also suggested that the misuse of home nebulizers may be an important factor in asthma deaths in children and young adults. If children must use an albuterol nebulizer, parents should be sure that it does not contain the preservative benzalkonium, which actually narrows the airways.

Asthma triggers a vicious emotional-physical cycle:

Breathlessness and wheezing incite a fear of suffocation and death, even in very small children.
This anxiety produces further constriction on the muscles surrounding the airways, which makes breathing even more difficult.

Caregivers must first focus on alleviating their own anxiety, which can heighten a child's own fears. The next step is to help the child relax. One method for this is as follows:

The child sits comfortably, bending slight forward with the eyes closed.
The hands are placed gently over the navel.
The child is then told to pretend the stomach is a balloon.
The "balloon" must be "blown up" by inhalation, not exhalation. The child can tell if this working because the hands will move slightly apart.
When the child breathes out, the "balloon" will be made flat.

This exercise both relaxes the child and discourages shallow, oxygen-poor breathing. Massaging the child in gentle circles on the chest is relaxing and may also loosen mucus.

Other recommendations include:

A child may also find relief by lying stomach-down on several pillows so that the head is slightly lower than the chest while the caregiver gently pats the back between the shoulder blades.
Warm liquids, such as soup or hot cider, are effective in loosening mucus and may also relax bronchial muscles. Cold fluids, like cold air, should be avoided.
Overhydration (too much liquid) can be harmful, however, so these drinks should not be forced on the child.
Warm, moist air from vaporizers can greatly ease and moderate asthma attacks.
Daily massages and breathing and relaxation techniques to reduce stress can be very helpful.

Many adults self-manage their asthma using daily monitoring of peak air flow with adjustments of the medications as needed. This involves the use of a peak flow meter, which measures peak expiratory flow rate (PEFR).

Click the icon to see an image of a peak flow meter.

Studies suggest, however, that for most children with asthma, an educational program is just as effective for managing the condition as monitoring. Most children do not need to monitor their peak air flow on any regular basis.

Quick-Relief Medications

These medications quickly control acute asthma attacks.

Beta2-agonists do not reduce inflammation or airway responsiveness but serve as bronchodilators, relaxing and opening constricted airways during an acute asthma attack. A short-acting inhaled beta2-agonist, taken as needed, is often the only medication used by children with chronic mild asthma.

Asthma is a disease in which inflammation of the airways causes airflow into and out of the lungs to be restricted. When an asthma attack occurs, mucus production is increased, muscles of the bronchial tree become tight, and the lining of the air passages swells, reducing airflow and producing the characteristic wheezing sound.

Specific short-acting beta2-agonists include:

Albuterol (Proventil, Ventolin), called salbutamol outside the U.S., is the standard short-acting beta2-agonist in America. Other similar beta2-agonists are isoproterenol (Isuprel, Norisodrine, Medihaler-Iso), metaproterenol (Alupent, Metaprel), pirbuterol (Maxair), terbutaline (Brethine, Brethaire, Bricanyl), and bitolterol (Tornalate). Isoetharine (Bronkometer, Bronkosol) is available in nebulizers.
Newer beta2-agonists, including levalbuterol (Xopenex), have more specific actions than the standard drugs. Xopenex is administered with a nebulizer, and studies have indicated that it is as effective as albuterol with fewer side effects. The original formulation of Xopenex was administered with a nebulizer. A new metered-dose inhaler formulation was launched at the end of 2005. It is approved for children age 4 years and older.

Short-acting bronchodilators are generally administered through inhalation and are effective for 3 - 6 hours. They relieve the symptoms of acute attacks, but they do not control the underlying inflammation. If asthma continues to worsen with the use of these drugs, a doctor may prescribe corticosteroids or other drugs to treat underlying inflammation.

Side Effects of Beta2-Agonists. Side effects of all beta2-agonists may include:

Anxiety
Tremor
Restlessness
Headache
Fast and irregular heartbeats. A doctor should be notified immediately if this side effect occurs.
These drugs should be taken with caution by children with diabetes or a history of seizures.
Beta2-agonists have serious interactions with certain drugs and parents should tell the doctor about any other medications their child is taking.

Loss of Effectiveness and Overdose. There has been some concern that short-acting beta2-agonists become less effective when taken regularly over time, increasing the risk for overuse. Over time, some patients may become tolerant to many effects of short-acting beta2-agonists. The degree to which this affects the airways is uncertain. In some studies, the duration of action has declined but the peak effect appears to be preserved, making these drugs still useful for acute attacks. Regular use of long-acting beta2-agonists may increase the chances of a reduced effect from the short-acting forms.

A 2005 landmark study suggested that patients’ differing clinical response to albuterol may be based on their genotype. Albuterol targets the beta-adrenergic receptor. In the Beta-Adrenergic Response by Genotype (BARGE) trial, researchers studied the effects of albuterol on patients with two different forms of this receptor. The results suggested that patients with the arginine form of the receptor did not respond to albuterol. These patients’ asthma symptoms actually improved when albuterol was not used. By contrast, patients with the glycine form of the receptor had improved asthma control with albuterol.

Inhaled ipratropium bromide (Atrovent) acts as a bronchodilator over time. Ipratropium bromide alone is only modestly beneficial for acute asthma attacks. In fact, the drug is not approved specifically for asthma. Some parents report benefit for treating wheezing in infants. It is also sometimes used in the emergency room to treat children with severe asthma to enhance the effects of intravenous beta2-agonists.

Common oral corticosteroids include prednisone/prednisolone, dexamethasone, methylprednisolone, and hydrocortisone. They reduce inflammation very effectively. A 2006 study indicated that oral prednisolone worked better than inhaled fluticasone for treating mild-to-moderate asthma attacks in children in emergency rooms. However, children often have difficulty taking these drugs because they have a bitter taste and can cause vomiting. Taking oral dexamethasone for 2 days may be as effective and more tolerable than the standard 5-day regimen of prednisone/prednisolone. Prolonged use of oral steroids has widespread and sometimes serious side effects, so they are not generally give to children for longer than a few days.

[See In-Depth Report #4: Asthma in adults.]

Long-Term Relief Medications

These medications are taken on a regular basis to prevent asthma attacks and control chronic symptoms.

Corticosteroids, also called glucocorticoids or steroids, are powerful anti-inflammatory drugs. Steroids are not bronchodilators (they do not relax the airways) and have little effect on symptoms. Instead, they work over time to reduce inflammation and prevent permanent injury in the lungs. They can also help prevent asthma attacks from occurring. Many studies have shown that the use of inhaled corticosteroids in patients with moderate-to-severe asthma significantly reduces the rate of rehospitalizations and deaths from asthma.

Inhalation of corticosteroids makes it possible to provide effective local anti-inflammatory activity in the lungs with minimal systemic effects. (By contrast, oral steroids have considerable side effects throughout the body.) Inhaled corticosteroids are recommended as the primary therapy under the following circumstances:

For any asthmatic condition more serious than occasional episodes of mild asthma. (Low-doses of inhaled steroids may even be safe and effective for some people with mild asthma, particularly those who find themselves using beta2-agonists daily.)
When treatment with bronchodilators is not effective.

Examples of inhaled corticosteroids:

Inhaled steroids include fluticasone (Flovent), budesonide (Pulmicort), triamcinolone (Azmacort and others), and flunisolide (AeroBid). In general, the newer drugs are more powerful than the older generation of inhaled drugs. Budesonide (Pulmicort Respules) is available in a jet nebulizer for children from 12 months to 8 years. It is the first such medication to be approved for children in this age group.
The FDA approved a new inhaled corticosteroid, mometasone furoate (Asmanex) was approved in 2005 for patients age 12 and older.
The older corticosteroid inhalants are beclomethasone (Beclovent, Vanceril) and dexamethasone (Decadron Phosphate Respihaler and others). They are less powerful than the newer steroids when delivered with standard inhalers. New inhalers that use very fine sprays (QVAR, Autohaler) to deliver the drugs deep into the lungs may prove to be as effective as the newer, more potent steroids.
Inhalers that combine both long-acting beta2-agonists and corticosteroids are also available. These include Symbicort (budesonide/formoterol), which was approved in 2006 for patients ages 12 years and older.

Expert guidelines recommend inhaled corticosteroids as the preferred first-line therapy for children with mild-to-moderate asthma. Nevertheless, they are still significantly underprescribed in the patients who need them most. An important 2007 study of 6 - 14 year old children with asthma compared inhaled corticosteroid therapy (fluticasone) with an inhaled corticosteroid/long-term beta2 agonist (fluticasone/salmeterol) and a leukotrine receptor antagonist (montelukast). The results indicated that fluticasone alone worked better than the other two treatments.

Researchers have been investigating whether early treatment with corticosteroids can help prevent the development of asthma in at-risk children. Two important 2006 studies in the New England Journal of Medicine suggested that while inhaled corticosteroids helped ease symptoms and reduce breathing problems in pre-school children at risk for asthma, they did not help protect against asthma development.

For now, experts caution against corticosteroids for infants and toddlers with mild asthma and urge close monitoring especially for children under age 5 with severe asthma who are receiving high doses. Because the newer potent drugs, particularly fluticasone, may produce major side effects similar to oral steroids, it is important when treating all children to aim for the lowest effective dose possible. Fortunately, studies suggest that low doses of fluticasone may achieve the same benefits as with high ones, thus reducing risks for serious side effects. Better delivery methods may also allow lower doses.

Side effects of inhaled steroids may include:

The most common side effects are throat irritation, hoarseness, and dry mouth. These effects can be minimized or prevented by using a spacer device and rinsing the mouth after each treatment.
Rashes, wheezing, facial swelling (edema), fungal infections (thrush) in the mouth and throat, and bruising are also possible but not common with inhalators.
Some children experience changes in mood, memory, and behavior. These changes are not permanent.
Some studies have suggested a higher risk for gum inflammation.
Oral steroids reduce bone density. Research reports that inhaled steroids -- both older and newer drugs -- may also affect bone growth and density. However, a number of studies report only a slight effect (about half an inch) on children's growth, which may be only temporary. It is still unknown if these drugs have any significant long-term effect on bone density. Calcium supplements may help prevent bone loss that is due to inhaled steroids.
It is not yet known whether inhaled steroids affect lung growth in very young children. Steroids administered using nebulizers are of particular concern.
There is also some concern that the stronger drugs, particularly fluticasone, suppress the adrenal system to a greater degree than other steroid inhalants. This effect, in turn, reduces levels of natural steroids -- notably cortisol, the major stress hormone. (This is a serious side effect of oral steroids).

Long-acting beta2-agonists are used in combination with inhaled corticosteroids for treating children with moderate-to-severe asthma. These drugs include include salmeterol (Serevent Diskus) and formoterol (Foradil Aerolizer). A single inhaler (Advair Diskus) that combines both salmeterol and the corticosteroid fluticasone is available for children age 4 years and older, and an inhaler (Symbicort) combining formoterol and the corticosteroid budesonide is approved for children age 12 years and older.

Long-acting beta2-agonists are used for preventing an asthma attack (not for treating attack symptoms). The effects of one dose of a long-acting beta2-agonist last for about 12 hours, so they are particularly effective during the night. These drugs also may be used for prevention of exercise-induced asthma in people and to protect against aspirin-induced asthma.

However, research indicates that long-acting beta2-agonists can worsen asthma by increasing symptom severity. These drugs may also increase the risk for asthma-related deaths. Experts are still trying to determine when long-acting beta2-agonists should be added to an asthma treatment plan. If a child’s symptoms do not improve or if symptoms worsen with this type of drug, the doctor will recommend discontinuing it. Patients should not, however, stop taking this drug or other asthma medications without first talking with their doctors.

Side Effects. Side effects of long-acting beta2-agonists are similar to the short-acting drugs.

Specific Warning on Salmeterol and Formoterol. In 2003 a "black box" warning was added to product packaging for drugs that contain salmeterol, including Serevent Diskus, and Advair Diskus. Serevent and Advair are approved for patients age 12 years and older. The warning was based on a study that demonstrated more serious and even fatal asthma episodes in patients who used the drug than in patients who used a placebo.

In 2006, the FDA updated the warning to include formoterol (Foradil Aerolizer, approved for patients 5 years and older). Warnings for salmeterol and formoterol products emphasize that these medicines can increase the risk of severe asthma episodes. Long-acting beta2-agonists require up to 20 minutes to achieve effectiveness, and there is a danger of overdose if a patient is not aware of this delay and takes additional doses to achieve faster relief. The FDA recommends that patients:

Use long-acting beta2-agonists only if other medicines (such as steroids) have not helped control asthma.
Use a short-acting bronchodilator, not a long-acting beta2-agonist, to treat sudden wheezing.
Do not use long-acting beta2-agonists to treat wheezing that is getting worse. Call your doctor if this situation occurs.
Do not stop using any asthma medicines without first talking to your doctor.

Cromolyn sodium (Intal) is both an anti-inflammatory drug and has antihistamine properties that block asthma triggers such as allergens, cold, or exercise. Cromolyn has been the anti-inflammatory drug of choice for prevention of asthma attacks in children over age 4 with chronic moderate asthma. It is not as effective as inhaled corticosteroids, however, for reducing hospitalization rates, improving symptoms, and reducing the use of beta2-agonists in children with persistent asthma. Still, cromolyn has a well-known long-term safety record, while the long-term adverse effects of corticosteroids in children are still not fully known. Many children who need asthma maintenance therapy will still do well on cromolyn. (It may not provide any real benefit for children under age 4.)

Nedocromil (Tilade) is similar to cromolyn and needs to be taken only once a day. It also prevents asthmatic reactions to cold and exercise. It is not used in very young children. A cromolyn nasal spray called Nasalcrom has been approved for over-the-counter purchase, but only to relieve nasal congestion caused by allergies. Patients should not use it for self-medication without the advice of a doctor.

Side Effects. Side effects of cromolyn include nasal congestion, coughing, sneezing, wheezing, nausea, nosebleeds, and dry throat. Nedocromil has an unpleasant taste, and some people have complained of nausea, headache, and spasms in the airways, but no serious side effects have been reported.

Leukotriene-antagonists (also called anti-leukotrienes or leukotriene modifiers) are oral medications that block leukotrienes. Leukotrienes are powerful immune system factors that, in excess, produce a battery of damaging chemicals that can cause inflammation and spasms in the airways of people with asthma. As with other anti-inflammatory drugs, leukotrienes are used for prevention and not for treating acute asthma attacks.

Leukotriene-antagonists include zafirlukast (Accolate), montelukast (Singulair), zileuton (Ziflo), and pranlukast (Ultair, Onon). These drugs are proving helpful for long-term prevention of asthma, including exercise-induced asthma and aspirin (or NSAID) -induced asthma. However, most studies to date have reported better success with inhaled corticosteroids than with the leukotriene-antagonists. A 2006 study of children with mild-to-moderate persistent asthma indicated that the corticosteroid fluticasone worked better than the leukotriene-antagonist montelukast in controlling symptoms. Nevertheless, some studies suggest that montelukast, which comes in a chewable tablet, may be particularly useful for managing asthma in small children (ages 2 - 5), since they have trouble with inhaled steroids.

Side Effects and Complications. Gastrointestinal distress is the most common side effect of leukotriene-antagonists. Very few other side effects have been reported. In general, these drugs appear to be safe and well-tolerated.

Of some concern are reports of Churg-Strauss syndrome in a few people taking zafirlukast or montelukast. Churg-Strauss syndrome is very rare, but it causes blood vessel inflammation in the lungs and can be life threatening. Oral steroids quickly resolve the problem. In fact, usually the syndrome has occurred in patients who were tapering off steroids and changing over to the leukotriene-antagonists. Some experts believe that, in such cases, the steroids may simply have masked the presence of the disorder, which then developed when the steroid drugs were withdrawn. Symptoms include severe sinusitis, flu-like symptoms, rash, and numbness in the hands and feet.

Other concerns are indications of liver injury in patients taking zileuton and zafirlukast when taken at higher than standard doses. No adverse effects on the liver have been reported to date with montelukast.

Theophylline (Theo-Dur, Theolair, Slo-Phyllin, Slo-bid, Constant-T, Respbid) is a mild-to-moderate bronchodilator that has been used to treat childhood asthma for more than 30 years. It is useful for treating nocturnal asthma and may also have anti-inflammatory qualities even in low doses.

Available in tablet, liquid, and injectable forms, some theophylline sustained-release tablets and capsules have a long duration of action and can therefore be taken once or twice a day with good results.

Side effects may include changes in behavior, mood, and memory. If theophylline is not taken exactly as prescribed, an overdose can easily occur. Toxicity can cause nausea, vomiting, headache, insomnia, and, in rare cases, disturbances in heart rhythm and convulsions. Contact a doctor immediately if any of these side effects occur.

The risks for these adverse effects are small if the drug is taken exactly as prescribed but the following precautions should be noted:

Infants tend to metabolize the drug extremely slowly and, therefore, should receive very low doses.
By the time children reach age 1, however, they metabolize the drug faster than adults. There is a risk, therefore, of toxic effects.
Fever and certain antibiotics may slow down the rate at which theophylline is eliminated from the body. In such cases, the doctor may want to reduce the dosage of theophylline.

If a child is taking theophylline on an ongoing basis, the doctor should monitor the drug level at the start of therapy and at regular intervals thereafter.

Omalizumab (Xolair) is FDA-approved for patients age 12 and older who have moderate-to-severe persistent asthma related to allergies. The first drug of this type to be approved for asthma, omalizumab is a monoclonal antibody (MAb), a genetically developed drug designed to attack very specific targets. Omalizumab is administered by injection every 2 - 4 weeks. It is used only to treat patients whose symptoms are not controlled by inhaled corticosteroids.

Omalizumab prevents the antibody immunoglobulin E (IgE) from triggering the inflammatory events that lead to asthmatic attacks. Studies have shown excellent benefits of the drug, including a reduced need for corticosteroids, fewer hospitalizations, and significant symptomatic improvements.

However, about 1 in 1,000 patients who take omalizumab develop anaphylaxis (a life-threatening allergic reaction). In 2007 the FDA requested the manufacturers of omalizumab to put a “boxed warning” on the medicine’s label emphasizing the drug’s risk for anaphylaxis. The boxed warning notes that patients can develop anaphylaxis after any dose of omalizumab, even if they had no reaction to a first dose. Anaphylaxis may occur up to 24 hours after the dose is given.

The FDA recommends that healthcare providers observe patients for at least 2 hours after an injection. Patients should also carry emergency self-treatment for anaphylaxis (such as an Epi-Pen) and know how to administer it. With an Epi-Pen, or similar auto-injector device, patients can quickly give themselves a life-saving dose of epinephrine.

Anaphylaxis symptoms include:

Difficulty breathing
Chest tightness
Dizziness
Fainting
Itching and hives
Swelling of the mouth and throat

[See In-Depth Report #4: Asthma in adults.]

Other Treatments

Alternative therapies are widely used by children, adolescents, and adults with asthma. In one study, nearly half of asthma or allergy sufferers resorted to alternative treatments. To date, however, evidence does not support most alternative therapies, including high-dose vitamins, urine injections, homeopathic remedies, and most herbal remedies.

Relaxation and Stress-Reduction Techniques. Patients report benefits from many stress reduction and physical techniques, such as acupuncture, hypnosis, breathing relaxation techniques, the Alexander technique, massage therapy, and meditation practices. There have been very few well-conducted studies supporting their use, however.

Acupuncture, hypnosis, and biofeedback are alternative ways to control pain. Acupuncture involves the insertion of tiny sterile needles, slightly thicker than a human hair, at specific points on the body.

Breathing Exercises. Some studies have suggested that breathing exercises or training may be helpful. A number of different methods are available. One example is the Buteyko breathing method, an experimental approach designed to increase levels of carbon dioxide in the body. To do this, patients are trained to reduce their volume of breath and to avoid hyperventilation (over-breathing). Some studies report that patients using this method reduce their use of medications and improve their quality of life. The system originated in Australia and is not yet widely available in the U.S.

Probiotics. Probiotics are beneficial bacteria that may possibly help protect against allergies and asthma. Antibiotic overuse and modern hygiene may specifically be reducing these helpful organisms. Look for probiotics in active yogurt cultures and in supplements, which are being studied for protection.

Herbal Remedies. Butterbur (also known as Petasites hybridus, butter dock, blatterdock, bog rhubarb, and exwort), is a traditional herbal remedy used for seasonal allergies and asthma. In a 2002 study, it was as effective and less sedating than a commonly prescribed antihistamine for treating seasonal allergies over a 2-week period. However, little research exists on its effect on asthma. Overall, there is scant evidence supporting the benefits of herbs and nutritional supplements for asthma control.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Managing Asthma

The more allergies a child has, the more severe the asthma. Making lifestyle changes to reduce allergy attacks and other triggers is extremely important.

House dust is a reservoir for pollen and dust mites. Some experts believe that reducing household allergens and pollutants in the home could reduce asthma in children by 40%.

Controlling for Dust. Spray furniture polish is very effective for reducing both dust and allergens. Air cleaners, filters for air conditioners, and vacuum cleaners with High Efficiency Particular Air (HEPA) filters can help remove particles and small allergens found indoors. Neither vacuuming nor the use of anti-mite carpet shampoo, however, is effective in removing mites in house dust. Vacuuming actually stirs up both mites and cat allergens. If possible, avoid carpets and rugs.

Click the icon to see an image of a HEPA air filter.

Bedding and Curtains. Many experts recommend reducing exposure to dust mites by enclosing mattresses and pillows in semipermeable coverings. (Vinyl mattress covers limit airflow and may also worsen, or even cause, asthma in children. Synthetic pillows may pose a significantly higher risk for severe asthma attacks in children than feather or no pillows.) However, several 2005 studies suggested that such covers do not prevent asthma or allergies. Replace curtains with shades or blinds, and wash bedding using the highest temperature setting.

Click the icon to see an image of dust mite prevention.

One study found that children sleeping in bottom bunk beds are significantly more likely to develop asthma than siblings occupying the upper bunks. Families with children who have asthma or allergies should avoid bunk beds or be sure that children with asthma sleep in the top bunk. Even with standard beds, it may be useful to have them sleep as high off the floor as possible.

Exterminating Pests (Cockroaches and Mice). Use professional exterminators to eliminate cockroaches. (One study reported that ridding a home of cockroaches and cleaning the house using standard housecleaning techniques failed to eliminate the cockroach allergens themselves.) Exterminate mice, and attempt to remove all dust, which might contain mouse urine and dander.

Reducing Humidity in the House. Although warm, moist air from vaporizers can greatly ease and moderate asthma attacks, living in a damp house is counterproductive. Dust mites thrive in humidity and damp houses increase the risk for mold, so on-going humidifiers can be unhelpful. If they are used, humidity levels should not exceed 40%, and humidifier should be cleaned daily with a vinegar solution.

Controlling Pets. People with asthma who already have pets and are not allergic to them probably have a low risk for developing such allergies later on. When children are exposed to more than one dog or cat during their first year, they have a much lower risk for allergies and asthma.

For children who have an existing allergy to pets, however, the pets should be given away or kept outside. If this isn't possible, they should at least be confined to carpet-free areas outside the bedroom. Cats harbor significant allergens, which can even be carried on clothing; dogs usually present fewer problems. Washing animals once a week can reduce allergens. Dry shampoos, such as Allerpet, are now available for both cats and dogs to remove allergens from skin and fur and are easier to administer than wet shampoos.

Many of the same substances trigger both allergies and asthma. Common allergens include pollen, dust mites, mold and pet dander. Other asthma triggers include irritants like smoke, pollution, fumes, cleaning chemicals, and sprays. Asthma symptoms can be substantially reduced by avoiding exposure to known allergens and respiratory irritants.

Preventing Exposure to Cigarette and Cooking Smoke. Parents who smoke are strongly urged to quit. Studies indicate that exposure to second-hand smoke in the home increases the risk for asthma and asthma-related emergency room visits in children. Even smoky cooking can worsen asthma.

Parental smoking has been shown to increase the airway responsiveness of infants as early as the first 2 - 10 weeks of life. This extends even to the fetus of pregnant women who smoke. Such mothers tend to have babies born at a low birth weight, which affects lung function and increases babies' risks for asthma.

Avoiding Outdoor Allergens. The following are some recommendations for avoiding allergens outside:

Avoid scheduling camping and hiking trips during times of high pollen count (generally, May and June for grass pollen and mid-August to October for ragweed).
Patients should avoid strenuous activity when ozone levels are highest, which usually occur in early afternoon, particularly on hot hazy summer days. Levels are lowest in early morning and at dusk.
Asthma attacks are often higher during thunderstorms. Some evidence points to a build-up of ozone that accompanies such storms. Other evidence suggests that the changing airflow patterns bring a sudden downdraft of air containing concentrations of pollens, small particles and allergens.
Patients who are allergic to mold should avoid barns, hay, raking leaves, and mowing grass.
Exposure to automobile fumes may worsen asthma. Fungi in car air conditioners can also be a problem.

Reducing Exposure to Air Pollution. Children breathe faster than adults, taking in more pollutants, and therefore are particularly susceptible to soot and other small particles in the air. A 2001 study found an association between higher rates of asthma and other health problems in children who were exposed to high levels of specific pollutants (particularly sulfur dioxide and nitrogen dioxide). Diesel fuel exhaust has also been associated with worsening asthma in children.

Some experts point out that asthma rates in North America have increased over recent years while the prevalence of many common air pollutants have declined. So pollution is unlikely to be a primary cause of asthma. Regardless of whether pollution is an important cause of asthma, evidence strongly suggests that it can affect existing asthma.

Patients with asthma and chronic allergic rhinitis may require daily medications. Patients with severe seasonal allergies may be advised to start medications a few weeks before the pollen season, and to continue it until the season is over.

Immunotherapy ("allergy shots") may help reduce asthma symptoms, and the use of asthma medications, in patients with known allergies. They may also help prevent the development of asthma in children with allergies. Immunotherapy poses some risk for severe allergic reactions, especially for children with poorly controlled asthma, so it is important that the doctor carefully evaluates the child’s asthma condition.

[See In-Depth Report #77: Allergic rhinitis.]

Weight Loss. Children who are both asthmatic and overweight may reduce asthma symptoms simply with weight loss.

Fruits, Vegetables, and Whole Grains. Healthy foods are important for lung function. Specific foods that may be important for healthy lungs contain antioxidants (deep green and yellow-orange fruits and vegetables), selenium (fish, red meat, grains, eggs, chicken, liver, garlic), plant chemicals called flavonoids (apples, onions), and magnesium (green leafy vegetables, nuts, whole grains, milk, and meats).

Fish Oil. Omega-3 fatty acids, found in cold water oily fish and in supplements (preferably DHA-EPA, the important compounds in fish oil) have anti-inflammatory effects. Some evidence suggests they may be helpful for people with asthma.

Caffeine. Caffeine has properties that are similar to the asthma drug theophylline. A major analysis of studies reported that caffeine improved lung function for up to 4 hours after consumption. Although tea and coffee are the major sources of caffeine, some sodas contain it and should be avoided when children have an asthma attack. (People who are going to have their lung function tested should avoid drinking coffee, tea, or other caffeinated beverages for at least 4 hours beforehand.)

Food Allergies. Although about 70% of people with asthma believe their symptoms are aggravated by food allergies, studies indicate that this belief may be true in only 5% of cases. If young children show signs of or test positive for food allergies, however, parents should be extra cautious in preventing exposure to any asthma trigger. Some doctors now counsel all children with asthma to avoid nuts entirely, and, of course, children who experience reactions to any foods should avoid them.

Chemicals that may pose some risk for an allergic reaction are monosodium glutamate, or MSG (found in some canned soups, cheese, and certain vegetables), and sulfites (preservatives in foods, such as frozen potatoes and tuna). Contrary to what many believe, dairy products do not appear to worsen asthma symptoms in people who are not already allergic to them.

Asthma is no reason to avoid exercise. Historically, about 10% of Olympic athletes have asthma. Some studies indicate that long-term exercise may help control asthma and reduce hospitalization.

Encourage children with asthma to swim and play sports, such as baseball, that will present less difficulty for them. Intense activities lasting less than 2 minutes, such as sprinting or competitive swimming, may cause fewer problems than longer-lasting exercises.

Young people who enjoy running should probably choose an indoor track to avoid pollutants. Swimming is excellent for people with asthma. Yoga practice, which uses both stretching, breathing, and meditation techniques, may have particular benefits. One study reported that two-thirds of patients who practiced yoga regularly were able to reduce or stop taking their asthma medications.

Patients should consult their doctors before starting any exercise program. Exercise-induced asthma is a limited condition that has specific recommendations.

People with asthma should try to minimize their risk for respiratory tract infections. Washing hands is a very simple but effective preventive measure.

Patients with asthma should ask their doctor about getting the influenza ("flu") vaccine and also whether they should receive the vaccination against pneumococcal pneumonia.

Zanamivir, a new drug used for treating influenza, is considered safe for patients with asthma 12 years of age or older. In one study, patients with asthma treated with zanamivir experienced fewer flu symptoms, and their lung function improved.

People with asthma have no higher rate of anxiety or depression than the general population. However, such emotions interact with the effects of asthma and its treatments in important ways:

Negative emotions can discourage compliance with medication and the ability to cope.
Poor control of asthma symptoms, in turn, increases the risk for negative emotions.
Stress and depression have been associated with more severe symptoms and even an increased risk of fatal asthma attacks.

Some evidence suggests that stress reduction techniques, a positive attitude, and relaxation techniques may be very helpful in the long-term management of asthma.

Double aortic arch

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Double aortic arch is an abnormal formation of the aorta—the large artery that carries blood from the heart to the rest of the body. It is a congenital problem, which means that it is present at birth.

Alternative Names

Aortic arch anomaly; Double arch

Causes, incidence, and risk factors

Double aortic arch is one of the most common types of vascular ring—a group of defects that affect the development of the baby’s aorta in the womb.

Normally, the aorta develops from one of several curved pieces of tissue (arches). In babies with this condition, it splits into several parts that go around the windpipe (trachea) and esophagus (tube that goes from the mouth to the stomach). The parts come together again in front of the spine.

As the baby grows in the womb, the body breaks down some of the arches, while others form into arteries. With vascular ring, some of the arches that should have changed into arteries or disappeared are still present at birth.

Babies with a double aortic arch have an aorta that is made up of two vessels instead of one. The two parts to the aorta have smaller arteries branching off of them. As a result, the two branches go around and press down on the windpipe and the tube that carries food from the mouth to the stomach (esophagus).

The right arch is bigger in most people with double aortic arch.

A double aortic arch may be seen in people with:

Double aortic arch is very rare. Vascular rings make up just a few of all congenital heart problems. Of these, a little more than half are double aortic arch. The condition occurs just as often in males as in females.

Symptoms

Because symptoms of double aortic arch are often mild, the problem may not be discovered until the child is a few years old.

Pressure from the aortic arch on the windpipe (trachea) and esophagus can lead to trouble breathing and swallowing. How severe the symptoms are depends on how much the aortic arch is pressing down on these structures.

Breathing symptoms include:

Bluish color to the skin (cyanosis)
High-pitched sound during breathing (stridor)
Noisy breathing
Repeated pneumonias
Wheezing

Digestive symptoms are rare, but may include:

Choking
Difficulty eating and swallowing
Vomiting

Signs and tests

A doctor will usually diagnose double aortic arch while the child is still an infant. However, the doctor may not notice any signs during a physical exam.

The following tests can help diagnose double aortic arch:

Chest x-ray
Scans that create cross-sectional images of the body (CT or MRI scan)
Ultrasound examination of the heart (echocardiography)
X-ray using a substance that outlines the esophagus (barium swallow)

Treatment

Surgery can be done to fix double aortic arch. The surgery separates off the smaller branch of the double aortic arch to relieve pressure on the esophagus and windpipe (trachea).

The surgeon ties off the smaller branch and separates it from the larger branch. Then the surgeon closes the ends of the aorta with stitches.

Expectations (prognosis)

Surgery can treat double aortic arch. Most children feel better right after surgery, although some may continue to have breathing symptoms.

In rare cases, if the arch is pressing down very hard on the airway, the child can die.

Complications

Abnormal connection between the esophagus and aorta (aortoesophageal fistula)
Failure to thrive
Respiratory infections
Wearing away of the lining of the esophagus (esophageal erosion) and windpipe

Calling your health care provider

Call your health care provider if your infant has symptoms of double aortic arch.

Prevention

There is no known way to prevent this condition.

Overview

Diagnosis

HEALTH GUIDE REFERENCE FROM A.D.A.M

Autism is a complex developmental disorder that appears in the first 3 years of life, although it is sometimes diagnosed much later. It affects the brain’s normal development of social and communication skills. Autism encompasses a wide range of behavior. The common features include impaired social interactions, impaired verbal and nonverbal communication, and restricted and repetitive patterns of behavior.

Signs and Symptoms

The symptoms may vary from moderate to severe. A combination of the following areas may be affected.

Communication:

Is unable to start or sustain a social conversation
Develops language slowly or not at all
Repeats words or memorized passages, like commercials
Doesn’t refer to self correctly (for example, says "you want water" when the child means "I want water")
Uses nonsense rhyming
Communicates with gestures instead of words

Social interaction:

Shows a lack of empathy
Does not make friends
Is withdrawn
Prefers to spend time alone, rather than with others
May not respond to eye contact or smiles
May actually avoid eye contact
May treat others as if they are objects
Does not play interactive games

Response to sensory information:

Has heightened or low senses of sight, hearing, touch, smell, or taste
Seems to have a heightened or low response to pain
May withdraw from physical contact because it is over-stimulating or overwhelming
Does not startle at loud noises
May find normal noises painful and hold hands over ears
Rubs surfaces, mouths or licks objects

Play:

Shows little pretend or imaginative play
Doesn’t imitate the actions of others
Prefers solitary or ritualistic play

Behaviors:

Has a short attention span
Uses repetitive body movements
Shows a strong need for sameness
"Acts up" with intense tantrums
Has very narrow interests
Demonstrates perseveration (gets stuck on a single topic or task)
Shows aggression to others or self
Is overactive or very passive

Causes

Autism is a physical condition linked to abnormal biology and chemistry in the brain. The exact causes of these abnormalities remain unknown, but this is a very active area of research. There are probably a combination of factors that lead to autism. Genetic factors seem to be important.

A number of other possible causes have been suspected, but not proven. They involve digestive tract changes, diet, mercury poisoning, vaccine sensitivity, and the body’s inefficient use of vitamins and minerals. Research suggests that heredity and early fetal development may play a causal role in autism, however studies show no association between risk of autism and parental factors such as age and socioeconomic status.

Some parents have heard that the Measles, Mumps, and Rubella (MMR) vaccine that children receive may cause autism. Although many clinicians still believe there is a link, several major studies have found no connection between the vaccine and autism. The American Academy of Pediatrics and the Centers for Disease Control and Prevention report that there is no proven link between autism and the MMR vaccine.

Some doctors attribute the increased incidence in autism to newer definitions of autism. The term “autism” now includes a wider spectrum of children.

Risk Factors

Autism affects males four times more often than females, and it may be inherited. In fact, about 50% of all boys with autism have a parent with the disease.

Autism occurs more frequently in children with rare genetic disorders and other medical conditions, such as tuberous sclerosis, phenylketonuria, neurofibromatosis, and epilepsy.

Diagnosis

All children should have routine developmental exams by their pediatrician. Further testing may be needed if there is concern on the part of the clinician or the parents. This is particularly true when a child fails to meet any of the following language milestones:

Babbling by 12 months
Gesturing (pointing, waving bye-bye) by 12 months
Single words by 16 months
Two-word spontaneous phrases by 24 months (not just echoing)
Loss of any language or social skills at any age

An evaluation of autism will often include a complete physical and neurologic examination. It may also include a specific diagnostic screening tool, such as:

Autism Diagnostic Interview - Revised (ADI-R)
Autism Diagnostic Observation Schedule (ADOS)
Childhood Autism Rating Scale (CARS)
Gilliam Autism Rating Scale
Pervasive Developmental Disorders Screening Test-Stage 3

Children with known or suspected autism will often have genetic testing (looking for chromosome abnormalities) and perhaps metabolic testing.

Treatment Approach

An early, intensive, appropriate treatment program will greatly improve the outlook for most young children with autism. An experienced specialist or team should design the individualized program. A variety of effective therapies are available. The best treatment plan may use a combination of techniques.

Teaching Programs

There are many types of teaching programs for children with autism. Some use a one-on-one teaching approach that relies on reinforced practice of various skills to get the child close to typical developmental functioning. Others use picture schedules and other visual cues to help the child work independently and to organize and structure their environments.

Medicine

Medicines are often used to treat behavior or emotional problems that people with autism may have. These include hyperactivity, impulsiveness, attention problems, irritability, mood swings, outbursts, tantrums, aggression, extreme compulsions that the child finds it impossible to suppress, sleep difficulty, and anxiety.

Treatment Options

Diet

Some children with autism appear to respond to a gluten-free or a casein-free diet. Gluten is found in foods containing wheat, rye, and barley. Casein is found in milk, cheese, and other dairy products. Not all experts agree that dietary changes will make a difference, and not all reports studying this method have shown positive results.

Some clinical studies show that children who have autism benefit from antioxidants like vitamin C. Parents and physicians have reported improvement in symptoms in children with autism who have been given certain supplements, including vitamin B, magnesium, cod liver oil and vitamin C.

If you are considering these or other dietary changes, seek guidance from both a gastroenterologist (doctor who specializes in the digestive system) and a registered dietitian. You want to be sure that the child is still receiving adequate calories, nutrients, and a balanced diet.

Touch Therapy and Massage

Research shows that some children with autism exhibit a reduction in symptoms after several weeks of touch therapy. In one clinical study, after 16 weeks of massage intervention parents reported feeling physically and emotionally closer to their children and children expressed a range of cues to initiate massage at home.

Several clinical studies have found that children who had Qigong massage (a type of massage that focuses on energy) showed a decrease in autistic behaviors and an increase in language development, as well as improvement in motor skills, sensory function, and general health.

Art, Music, and Pet Therapy

Art therapy, music therapy, animal therapy, and sensory integration therapy provide opportunities for children who have autism to develop social and communication skills.

Art therapy offers a child a nonverbal way to express his or her feelings.
Music therapy involving singing helps develop the child’s speech and language skills. In fact, research shows that any music intervention effectively reduces symptoms for children and adolescents with autism.
Animal therapy may include therapeutic riding programs on horses and swimming with dolphins. These types of therapies can help improve the child’s motor skills, while also building self-confidence. In fact, some studies show that children who interact with dolphins learn faster and retain more information than children who learned in a classroom setting.
Sensory integration focuses on normalizing extreme reactions to sensory input. It tries to help children reorganize and integrate their sensory information so they can better understand the outside world.

While there is little scientific evidence supporting these therapies, many parents and therapists report noticeable improvement in a child’s behavior and communication skills as well as a sense of enjoyment.

Prognosis/Possible Complications

Autism remains a challenging condition for individuals and their families, but the outlook is much better than it was a generation ago. Today, with appropriate therapy, clinicians can help reduce many of the symptoms of autism, though most people will be affected on some level throughout their lives.

Autism can be associated with other disorders that affect the brain, such as mental retardation or fragile X syndrome. Some people with autism will develop seizures.

Other Considerations

Viral infection during the first three months of pregnancy -- particularly with rubella -- is a suspected cause of autism.

Diet and good health

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

An age-appropriate diet is one that provides adequate nutrition and is appropriate for a child's state of development.

Alternative Names

Diet - age appropriate

Recommendations

BIRTH TO 4 MONTHS OF AGE

During the first 4 - 6 months of life, infants need only breast milk or formula to meet all their nutritional needs.

If breastfeeding, a newborn may need to nurse 8 - 12 times per day (every 2 - 4 hours), or on demand. By 4 months, the baby is likely to cut back to 4 - 6 times per day, however, the quantity of breast milk consumed at each feeding will increase.

Formula-fed babies may need to eat about 6 - 8 times per day, starting with 2 - 5 ounces of formula per feeding (for a total of 16 - 35 ounces per day). As with breastfeeding, the number of feedings will decrease as the baby gets older, but the amount of formula will increase to approximately 6 - 8 ounces per feeding.

Never give honey to an infant, as it may contain the spores that cause botulism. An infant's immune system is not fully developed to fight off this disease.

Although an infant may sleep through the night, waking to feed may be necessary if the infant is not eating enough during the day or if they are underweight. Routine check-ups with your physician to monitor your child's growth will ensure they are eating adequately during the day. Your doctor or dietitian will inform you if waking to feed is recommended.

4 - 6 MONTHS OF AGE

At 4 - 6 months of age an infant should be consuming 28 - 45 ounces of formula, and is often ready to start the transition to solid foods. Starting solids too soon may cause the infant to choke if they are not physically ready.

There are several developmental milestones to indicate an infant is ready to eat solid foods:

The birth weight has doubled
The baby has good control of head and neck
The baby can sit up with some support
The baby can show fullness by turning the head away or by not opening the mouth
The baby begins showing interest in food when others are eating.

Start solid feedings with iron-fortified baby rice cereal mixed with breast milk or formula to a thin consistency. The cereal may be mixed to a thicker consistency as the baby learns to control it in his mouth.

Initially, offer cereal 2 times per day in servings of 1 or 2 tablespoons (dry amount, before mixing with formula or breast milk). Gradually increase to 3 or 4 tablespoons of cereal. Cereal should not be given in a bottle unless a doctor or dietitian recommends it, for example, for reflux.

Once the baby is eating rice cereal routinely, you may introduce other iron-fortified instant cereals. Only introduce one new cereal per week so you can watch for an intolerance or allergy.

Never put a child to bed with a bottle as this can cause bottle mouth, resulting in tooth decay. Use plain water if a bottle is necessary. Discuss use of water with your physician. (In some cases, use of excess water can lead to seizures in children.)

6 - 8 MONTHS

Continue to offer breast milk or formula 3 - 5 times per day. The consumption of formula or breast milk will begin to level off as solid foods become a source of nutrition. After a baby has tried a variety of different baby cereals, try strained fruits and vegetables.

For strained fruits and vegetables, introduce one at a time waiting 2 - 3 days in between to check for any allergic reaction. Start with plain vegetables such as green peas, potatoes, carrots, sweet potatoes, squash, beans, beets; and plain fruits such as bananas, applesauce, apricots, pears, peaches, and melon.

Some dietitians recommend introduction of a few vegetables before fruits as the fruit's sweetness may make a less-sweet food such as vegetables less appealing. Give fruits and vegetables in 2 - 3 tablespoon servings and offer about 4 servings per day.

Amounts of fruits and vegetables consumed per day will vary between 2 tablespoons and 2 cups depending on the size of your child and how well the child eats fruits and vegetables. The consistency of foods offered may be gradually increased as your child tolerates.

Finger foods may be offered in small amounts, but avoid foods such as apple chunks or slices, grapes, hot dogs, sausages, peanut butter, popcorn, nuts, seeds, round candies, and hard chunks of uncooked vegetables that may cause choking.

Soft cooked vegetables, washed and peeled fruits, graham crackers, melba toast, noodles are good finger foods, but salted and/or sugared foods are not recommended. Teething foods, such as toast strips, unsalted crackers, bagels, and teething biscuits may also be introduced at this time.

8 - 12 MONTHS OF AGE

Breast milk or formula should be offered three to four times per day at this age. At 8 - 12 months of age, a baby will be ready to try strained or finely chopped meats. For breastfed infants, start meats at 8 months of age (breast milk is not a rich source of iron, but infants have adequate iron stores to last until 8 months of age when iron-rich foods such as meats can be given).

As with other foods, offer only 1 new meat per week in 3 - 4 tablespoon servings -- use strained and finely ground meats, frankfurters, or meat sticks. Serving sizes for fruits and vegetables increases to 3 - 4 tablespoons, four times per day. Eggs may be given 3 - 4 times per week, but only the yolk until the baby is 1 year old, as some babies are sensitive to egg whites.

By the age of 1, most children are off the bottle. If the child still uses a bottle, it should contain water only.

1 YEAR OF AGE

After a baby is 1-year old, whole milk may replace breast milk or formula. Children under the age of 2 should not be given low-fat milk (2%, 1%, or skim) as they need the additional calories from fat to ensure proper growth and development.

Children under the age of 1 should not be given whole milk as it has been shown to cause low blood counts. Cheese, cottage cheese, and yogurt, however, may be given in small amounts.

The 1-year-old child should be getting much of their nutrition from meats, fruits and vegetables, breads and grains, and the dairy group, especially whole milk.

Providing a variety of foods will help to ensure enough vitamins and minerals. Toddlers do not grow as rapidly as babies do, so their nutritional needs relative to their size decrease during the second year of life. Although they continue to gain weight, they no longer double their weight as infants do.

Keep in mind, however, that toddlers are becoming more and more active as they learn to crawl and walk. Toddlers and small children will usually eat only small amounts at one time, but will eat frequently (4 - 6 times) throughout the day, so snacking is strongly encouraged.

Feeding Tips:

Feeding solids too early is not recommended and can result in overfeeding.
Offer only one new food at a time. Offer the new foods for a few days. Watch for allergic reactions (hives, vomiting, diarrhea).
Do not feed solids in a bottle.
If your child dislikes the new food, try giving it again later.

SAFETY FIRST

Feed the baby directly from the jar only if you use the entire jar contents, otherwise use a dish to prevent contamination with food-borne illness.
Opened containers of baby's food should be covered and stored in a refrigerator for no longer than 2 days.
Use a small spoon to feed the baby.
A baby put to bed with a bottle (milk, fruit juice, or sweetened beverage) can develop bottle mouth, resulting in tooth decay. Use plain water if a bottle is necessary.
Avoid foods that may cause the baby to choke -- popcorn, nuts, potato chips, whole kernel corn, berries, grapes, hot dogs, raw vegetables, raisins, dry flake cereals.

OTHER TIPS

Water can be offered between feedings.
Feeding sweets or sweetened beverages is not recommended because they will spoil the appetite and contribute to tooth decay.
Salt, sugar, and strong spices are not recommended.
Caffeine products are not recommended (soft drinks, coffee, tea, chocolate).
A fussy baby may need attention, rather than food.

OLDER CHILDREN

Throughout childhood and adolescence, it is important that the diet include a variety of foods for proper development. The principles of the food guide pyramid apply to a child's diet as well as an adult's, although portions and number of servings per day are obviously less for children.

After the age of 2, it is recommended that the diet be moderately low in fat, as diets high in fat may contribute to heart disease, obesity, and other health problems later in life.

In areas where water is not fluoridated, fluoride supplementation is recommended. A diet that contains a variety of foods from each of the food groups (breads and grains, meats, fruits and vegetables, and dairy) will help prevent nutrient deficiencies.

Both the American Medical Association and the American Dietetic Association recommend that healthy children should get all their nutrients from foods rather than vitamin supplements.

The nutrients that are most likely to be deficient in a child's diet are calcium, iron, vitamin C, vitamin A, folic acid, and vitamin B6. The American Academy of Pediatrics does not support routine supplementation for normal, healthy children. However, there is no significant risk if a parent wishes to give their child a standard pediatric multi-vitamin.

Children who consume little or no dairy products are at particular risk for calcium deficiency that can interfere with bone growth and development. Foods that are good sources of calcium include low-fat or nonfat milk, yogurt, and cheeses. Other foods such as broccoli, cooked greens, and canned salmon (with bones) will also provide a source of calcium in the diet, however it is often difficult to get children to consume adequate quantities of these foods.

Iron requirements vary by age, rate of growth, iron stores, increasing blood volume, and rate of absorption from food sources. Adolescent girls will have increased iron needs due to menstrual losses. Food sources of iron include meat, fish, poultry, iron-fortified cereals, spinach greens, and dried beans and peas.
