The possible side effects of Azmacort (triamcinolone) include sore throat, nosebleed, coughing, headache, and runny nose. Serious side effects are indicated by white patches in the throat or nose. Symptoms of allergic reaction include rash, itch, swelling, severe dizziness, or trouble breathing. You are advised to notify your doctor of any experienced side effects and to obtain immediate medical assistance for allergic reaction or serious side effects. Of course this medication should only be used as prescribed by and under the care of a medical doctor.
DefinitionAsthma is a disease of the respiratory system, which causes swelling and narrowing of the airways. Pediatric asthma refers to asthma in children.Alternative NamesPediatric asthmaCauses, incidence, and risk factorsThis article discusses asthma in children. For a more general discussion about the disease, please see asthma.Asthma is commonly seen in children. It is a leading cause of hospital stays and school absences. Children with asthma may be able to breathe normally most of the time. When they encounter a substance that can cause problems (a "trigger"), an asthma attack (exacerbation) can occur.Common asthma triggers include:Animals (hair or dander)Aspirin and other medicationsChanges in weather (most often cold weather)Chemicals in the air or in foodDustExerciseMoldPollenStrong emotionsTobacco smokeViral infections, such as the common coldIn recent years, there has been a worldwide increase in the number of children with asthma. This trend has been linked to environmental factors, including air pollution. However, it is important to understand that indoor triggers can play just as much of a role as outdoor triggers in bringing on an asthma attack.Children's airways are narrower than those of adults. This means that triggers that may cause only a slight problem in an adult can create more serious problems in children. In children, an asthma attack can appear suddenly with severe symptoms. For this reason, it is important that asthma be diagnosed and treated correctly. Some children may need to take medicine every day to prevent attacks, even when they do not have symptoms.SymptomsDifficulty breathingFast (rapid) breathingShortness of breath, even at restTightness in the chestCoughNote: A persistent night-time cough is one common sign of asthma, even in children without other symptoms.Emergency symptoms:Difficulty breathingBluish color to the lips and faceSevere anxiety due to shortness of breathRapid pulseSweatingDecreased level of alertness, such as severe drowsiness or confusionSigns and testsThe doctor will use a stethoscope to listen to the lungs. Asthma-related sounds may be heard. However, lung sounds are usually normal between asthma episodes.Tests may include:Lung function testsPeak flow measurementsChest x-rayAllergy skin or blood testsArterial blood gasEosinophil count (a type of white blood cell)TreatmentYou and your child's pediatrician or allergist should work together as a team to create and carry out an asthma action plan. This plan should outline how toAvoid asthma triggersMonitor symptomsTake medicinesThe plan should also tell you when to call the nurse or doctor.You should also have an emergency plan that outlines what to do when your child's asthma flares up. If your child is in school, make sure teachers, school nurses, physical education teachers, and coaches know about your child's need to take asthma medicine. Find out what you need to do to let your child take his medicine during school hours. (You may need to sign a consent form.) Make sure the school has a copy of your child's asthma action plan.MEDICATIONSThere are two basic kinds of medication for the treatment of asthma:Long-term control medicationsQuick relief or "rescue" medicationsLong-term control medications are used on a regular basis to prevent asthma symptoms, not for treatment during an attack. They should be taken every day, even when you do not have symptoms. Some people may need more than one long-term control medication.Types of long-term control medications include:Inhaled steroids (such as Azmacort, Vanceril, AeroBid, Flovent) prevent swelling in your airways - these are almost the first choice of treatmentLeukotriene inhibitors (such as Singulair and Accolate)Long-acting bronchodilators (such as Serevent) help open airways - are usually used in combination with inhaled steroidsCromolyn sodium (Intal) or nedocromil sodiumAminophylline or theophylline (not used as frequently as in the past)Quick relief, or rescue, medications are used to relieve symptoms during an attack. These include:Short-acting bronchodilators (inhalers), such as Proventil, Ventolin, Xopenex, and others.Corticosteroids, such as prednisone or methylprednisolone) given by mouth or into a veinAlthough these are the same medications used to treat adults, there are different inhalers and dosages especially for children. In fact, children often use a nebulizer to take their medicine rather than an inhaler, because it can be difficult for them to use an inhaler properly. Children who use an inhaler should also use a "spacer" device, which helps them to get the medicine into the lung properly.Children with mild asthma (do not have symptoms very often) may only need quick relief medication as needed. Those who more severe asthma need to take control medications on a regular basis to prevent symptoms.A child who is having a severe asthma attack should be immediately seen by a doctor. The child may need to stay in the hospital, and may be given oxygen and medicines by an intravenous line (IV).ELIMINATING TRIGGERSYou and your family can help control a child's asthma by helping get rid of the indoor triggers that make symptoms worse.If possible, keep pets outdoors, or at least away from the child's bedroom.No one should smoke in a house or around a child with asthma. Eliminating tobacco smoke from the home is the single most important thing a family can do to help a child with asthma. Smoking outside the house is not enough. Family members and visitors who smoke carry smoke residue in and on their clothes and hair -- this can trigger asthma symptoms.Keeping humidity levels low and fixing leaks can reduce growth of organisms such as mold. Keep the house clean and keep food in containers and out of bedrooms -- this helps reduce the possibility of cockroaches, which can trigger asthma attacks. Bedding can be covered with "allergy proof" polyurethane-coated casings to reduce exposure to dust mites. Detergents and cleaning agents in the home should be unscented.All of these efforts can make a significant difference to the child with asthma, even though it may not be obvious right away.KEEPING AN EYE ON YOUR CHILD'S ASTHMAA peak flow meter is a simple device that you and your child can use at home to monitor lung function. The meter can help you see if an attack is coming, sometimes even before any symptoms appear. This allows you to take preventative measures. Peak flow measurements can help show when medication is needed, or other action needs to be taken. Peak flow values of 50-80% of the child's personal best results mean a moderate asthma attack is occurring or going to occur, while values below 50% suggest a severe attack.Children under age 5 may not be able to use a peak flow meter well enough to make the numbers useful. An adult should always watch carefully for a child's asthma symptoms. It's a good idea to start using peak flow meters before age 5 to get the child used to them.Expectations (prognosis)With proper treatment and a team approach to managing asthma, most children with asthma can live a normal life. Asthma, however, can be a life-threatening disease. It is important for families to work together with health care professionals to develop a plan to properly care for the child.ComplicationsThe complications of asthma can be severe. Some include:Persistent coughLack of sleep due to nighttime symptomsDecreased ability to exercise and take part in other activitiesMissed schoolMissed work for parentsEmergency room visits and hospital staysTrouble breathing that requires breathing assistance (ventilator)Permanent changes in the function of the lungsDeathCalling your health care providerCall your health care provider if you think that a child has symptoms of asthma. It is very important for asthma to be diagnosed and treated early in order to reduce the risk of complications. If your child is having trouble breathing or having an asthma attack, seek medical attention immediately.PreventionThere is no fool-proof method to prevent asthma attacks. The best way to reduce the number of attacks is to eliminate triggers (especially cigarette smoke) and follow the asthma plan that you develop with your doctor. When families take control of their home environment, asthma symptoms and attacks can be significantly decreased.ReferencesNational Asthma Education and Prevention Program Expert Panel Report 3: Guidelines for the Diagnosis and Management of Asthma.

When an asthma attack occurs, the muscles surrounding the airways become tight and the lining of the air passages swells. This reduces the amount of air that can pass by.Asthma is commonly seen in children. It is a leading cause of hospital stays and school absences. Asthma and allergies often occur together.

They can include:Shortness of breathFeeling like you are out of breathGasping for airHaving trouble breathing outBreathing faster than normalWhen breathing gets very difficult, the skin of your chest and neck may suck inward.Other symptoms of asthma in children include:Coughing that sometimes wakes the child up at night; it may be the only symptomDark bags under the eyesFeeling tiredIrritabilityTightness in the chestWheezing, a whistling sound made when breathing, that may be more noticeable when the child breathes outThe type and pattern of your child's asthma symptoms may vary. They may be occur often or only when certain triggers are present. Some children are more likely to have asthma symptoms at night.Signs and testsThe doctor will to listen to the child's lungs. Asthma-related sounds may be heard. However, lung sounds are often normal between asthma episodes.The doctor will have your child breathe into a device called a peak flow meter. Peak flow meters can tell you and your doctor how well the child can blow air out of the lungs. If the airways are narrow and blocked due to asthma, peak flow values drop.You and your child will learn to measure peak flow at home.Tests may include:Lung function testsChest x-rayAllergy testingEosinophil count (a type of white blood cell)TreatmentYou and your child's pediatrician or allergist should work together as a team to create and carry out an asthma action plan.This plan should outline how toAvoid asthma triggersMonitor symptomsMeasure peak flowTake medicinesThe plan should also tell you when to call the nurse or doctor.You should also have an emergency plan that outlines what to do when your child's asthma flares up.

Have your health care provider show you how to correctly use an inhaler.Younger children can use a nebulizer to take their medicine rather than an inhaler. A nebulizer turns asthma medicine into a mist that you breathe in.ELIMINATING TRIGGERSIt is important to know what things make your child's asthma worse. These are called asthma "triggers." Avoiding them is the first step toward helping your child feeling better.See: Avoiding asthma triggersIf possible, keep pets outdoors, or at least away from the child's bedroom.No one should smoke in a house or around a child with asthma. Eliminating tobacco smoke from the home is the single most important thing a family can do to help a child with asthma. Smoking outside the house is not enough.

Checking "peak flow" is one of the best ways to control asthma. It can help you keep your child's asthma from getting worse. Asthma attacks do NOT usually come on without warning.Children under age 5 may not be able to use a peak flow meter well enough to make the numbers useful. An adult should always watch carefully for a child's asthma symptoms. It's a good idea to start using peak flow meters before age 5 to get the child used to them.See also: How to make peak flow measurements a habitExpectations (prognosis)With proper treatment and a team approach to managing asthma, almost all children with asthma can live a normal life. However, poorly controlled asthma may lead to missed school, problems playing sports, missed work for parents, and multiple visits to the doctor's office and emergency room.Many times, asthma symptoms occur much less often or disappear as the child gets get older. However, if the child's asthma is not well controlled, it can lead to permanent changes in lung function.Asthma can rarely be a life-threatening disease. It is important for families to work together with health care professionals to develop a plan to properly care for the child.ComplicationsThe complications of asthma can be severe.

DefinitionAsthma is an inflammatory disorder of the airways, which causes attacks of wheezing, shortness of breath, chest tightness, and coughing.See also: Pediatric asthmaAlternative NamesBronchial asthma; Exercise-induced asthmaCauses, incidence, and risk factorsAsthma is caused by inflammation in the airways. When an asthma attack occurs, the muscles surrounding the airways become tight and the lining of the air passages swell. This reduces the amount of air that can pass by, and can lead to wheezing sounds.Most people with asthma have wheezing attacks separated by symptom-free periods. Some patients have long-term shortness of breath with episodes of increased shortness of breath. In others, a cough may be the main symptom. Asthma attacks can last minutes to days and can become dangerous if the airflow becomes severely restricted.In sensitive individuals, asthma symptoms can be triggered by breathing in allergy-causing substances (called allergens or triggers).Common asthma triggers include:Animals (pet hair or dander)DustChanges in weather (most often cold weather)Chemicals in the air or in foodExerciseMoldPollenRespiratory infections, such as the common coldStrong emotions (stress)Tobacco smokeAspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) provoke asthma in some patients.Many people with asthma have an individual or family history of allergies, such as hay fever (allergic rhinitis) or eczema. Others have no history of allergies.SymptomsCough with or without sputum (phlegm) productionPulling in of the skin between the ribs when breathing (intercostal retractions)Shortness of breath that gets worse with exercise or activityWheezing Comes in episodesMay be worse at night or in early morningMay go away on its ownGets better when using drugs that open the airways (bronchodilators)Gets worse when breathing in cold airGets worse with exerciseGets worse with heartburn (reflux)Usually begins suddenlyEmergency symptoms:Bluish color to the lips and faceDecreased level of alertness such as severe drowsiness or confusion, during an asthma attackExtreme difficulty breathingRapid pulseSevere anxietydue to shortness of breathSweatingAdditional symptoms that may be associated with this disease:Abnormal breathing pattern --breathing out takes more than twice as long as breathing inBreathing temporarily stopsChest painNasal flaringTightness in the chestSigns and testsAllergy testing may be helpful in identifying allergens in people with persistent asthma. Common allergens include pet dander, dust mites, cockroach allergens, molds, and pollens. Common respiratory irritants include tobacco smoke, pollution, and fumes from burning wood or gas.The doctor will use a stethoscope to listen to the lungs. Asthma-related sounds may be heard. However, lung sounds are usually normal between asthma episodes.Tests may include:Arterial blood gasBlood tests to measure eosinophil count (a type of white blood cell) and IgE (a type of immune system protein called an immunoglobulin)Chest x-rayLung function testsPeak flow measurementsTreatmentThe goal of treatment is to avoid the substances that trigger your symptoms and to control airway inflammation. You and your doctor should work together as a team to develop and carry out a plan for eliminating asthma triggers and monitoring symptoms.There are two basic kinds of medication for the treatment of asthma:Long-acting medications to prevent attacksQuick-relief medications for use during attacksLong-term control medications are used on a regular basis to prevent attacks, not to treat them. Such medicines include:Inhaled corticosteroids (such as Azmacort, Vanceril, AeroBid, Flovent) prevent inflammationLeukotriene inhibitors (such as Singulair and Accolate)Long-acting bronchodilators (such as Serevent) help open airwaysOmilizumab (Xolair), which blocks a pathway that the immune system uses to trigger asthma symptomsCromolyn sodium (Intal) or nedocromil sodium (Tilade)Aminophylline or theophylline (not used as frequently as in the past)Sometimes a single medication that combines steroids and bronchodilators are used (Advair, Symbicort)Quick relief, or rescue, medications are used to relieve symptoms during an attack. These include:Short-acting bronchodilators (inhalers), such as Proventil, Ventolin, Xopenex, and othersCorticosteroids, such as methylprednisolone, may be given directly into a vein (intravenously), during a severe attack, along with other inhaled medicationsPeople with mild asthma (infrequent attacks) may use quick relief medication as needed. Those with persistent asthma should take control medications on a regular basis to prevent symptoms. A severe asthma attack requires a check up by a doctor and, possibly, a hospital stay, oxygen, and medications through a vein (IV).A peak flow meter is a simple device to measure how quickly you can move air out of your lungs. It can help you see if an attack is coming, sometimes even before any symptoms appear. Peak flow measurements can help show when medication is needed, or other action needs to be taken. Peak flow values of 50-80% of a specific person's best results are a sign of a moderate asthma attack, while values below 50% are a sign of a severe attack.Support GroupsThe stress caused by illness can often be helped by joining a support group, where members share common experiences and problems.See: Asthma and allergy - support groupExpectations (prognosis)There is no cure for asthma, although symptoms sometimes improve over time. With proper self management and medical treatment, most people with asthma can lead normal lives.ComplicationsThe complications of asthma can be severe. Some include:DeathDecreased ability to exercise and take part in other activitiesLack of sleep due to nighttime symptomsPermanent changes in the function of the lungsPersistent coughTrouble breathing that requires breathing assistance (ventilator)Calling your health care providerCall for an appointment with your health care provider if asthma symptoms develop.Call your health care provider or go to the emergency room if:An asthma attack requires more medication than recommendedSymptoms get worse or do not improve with treatmentYou have shortness of breath while talkingYour peak flow measurement is 50-80% of your personal bestGo to the emergency room if:Drowsiness or confusion developsThere is severe shortness of breath at restThe peak flow measurement is less than 50% of your personal bestYou have severe chest painPreventionAsthma symptoms can be substantially reduced by avoiding known triggers and substances that irritate the airways.Bedding can be covered with "allergy proof" casings to reduce exposure to dust mites. Removing carpets from bedrooms and vacuuming regularly is also helpful. Detergents and cleaning materials in the home should be unscented.Keeping humidity levels low and fixing leaks can reduce growth of organisms such as mold. Keep the house clean and keep food in containers and out of bedrooms -- this helps reduce the possibility of cockroaches, which can trigger asthma attacks in some people.If a person is allergic to an animal that cannot be removed from the home, the animal should be kept out of the patient's bedroom. Filtering material can be placed over the heating outlets to trap animal dander.Eliminating tobacco smoke from the home is the single most important thing a family can do to help a child with asthma. Smoking outside the house is not enough. Family members and visitors who smoke outside carry smoke residue inside on their clothes and hair -- this can trigger asthma symptoms.Persons with asthma should also avoid air pollution, industrial dusts, and other irritating fumes, as much as possible.ReferencesNational Asthma Education and Prevention Program Expert Panel Report 3: Guidelines for the Diagnosis and Management of Asthma.
