Exercise-induced bronchospasm (EIB) can represent a substantial barrier to physical activity. We present the cases of two patients with EIB, one with asthma, and one without asthma, who were evaluated at our primary care practice. The first case was a 44-year-old man with a history of seasonal allergic rhinitis but no asthma, who reported difficulty breathing when playing tennis. The second cas...

OBJECTIVE The aim of the present study was to determine whether aerobic exercise involving an active video game system improved asthma control, airway inflammation and exercise capacity in children with moderate to severe asthma. DESIGN A randomized, controlled, single-blinded clinical trial was carried out. Thirty-six children with moderate to severe asthma were randomly allocated to either ...

Asthma is the most common cause of recurrent wheezing, cough and dyspnea in childhood. Delay in diagnosis and lack of appropriate treatment can cause sustained changes which decrease respiratory capacity of children in future. Therefore, identifying the symptoms relating to asthma is the key for timely diagnosis and treatment of this disease. This study was done to investigate asthma incidence ...

OCTOBER 2003 389 A 16-year-old boy comes into your office and says he needs inhaled albuterol. He wants to play soccer but becomes short of breath when he is out on the soccer field. He currently uses the drug once a week during exercise, and he tells you that his albuterol keeps him from being so short of breath. When you listen to his chest, it is clear. His history includes no complaints of ...

Patients with asthma often report symptoms of exercise-induced bronchoconstriction. We performed cardiopulmonary exercise testing to establish the cause of exercise limitation in patients with asthma, under treatment, who reported symptoms of exercise-induced bronchoconstriction. Ten of the 42 patients meeting criteria for inclusion in our study (24%) developed exercise-induced bronchoconstrict...

BACKGROUND Conflicting views exist over whether responsiveness of the airways to hypertonic saline relates to non-specific bronchial hyperresponsiveness measured by histamine or methacholine challenge. The bronchoconstrictor responses to exercise and hypertonic saline are reported to be closely related, but the relationship between the symptoms of exercise induced asthma and airway responsivene...

OBJECTIVES To compare the physical activity levels of children with and without asthma and evaluate predictors of activity level in children with asthma. METHODS Parents of 137 children with asthma and 106 controls 6 to 12 years old who attended an urban primary care pediatric clinic were interviewed by telephone. A structured survey evaluated 1 day's total activity and the number of days act...

The article in this issue of RESPIRATORY CARE by Burnett et al1 reports that 34 of 80 college athletes had exerciseinduced bronchoconstriction (EIB), most in the absence of symptoms. The authors further suggest that these athletes are at risk and that the identification of those with EIB may prevent morbidity and mortality. The implication is that the presence of EIB is evidence for asthma. But...

Nedocromil sodium (Tilade) is a new anti-asthma drug that has selective mucosal mast cell stabilising properties.' In single dose human studies nedocromil has been shown to protect against exercise induced asthma,2 while in clinical studies, in which it has been administered four times a day for one month, improvements have been shown in the control of adult asthma.3 There are no published data...
