The prevalence of asthma was studied in a ice hockey team compared with both a floor ball team and the Swiss population. Lung function, bronchial hyperresponsiveness to methacholine, asthma symptoms and exercise-induced asthma were measured in a cross-sectional prospective study. A positive response to the methacholine bronchial provocation test was found in 34.6% of the ice hockey players and ...

Allergic and hypersensitivity reactions such as anaphylaxis and asthma exacerbations may occur during air travel. Although the exact incidence of in-flight asthma and allergic emergencies is not known, we have concerns that this subject has not received the attention it warrants. There is a need to provide passengers at risk and airlines with the necessary measures to prevent and manage these e...

BACKGROUND AND OBJECTIVES Worldwide incidence of bronchial asthma is on rise. Infections either viral or bacterial and various environmental factors are considered as major risk factors for exacerbations in various studies. Despite of awareness and preventive strategies to risk factors, exacerbations largely remain uncontrolled, therefore the study was planned to review the existing risk factor...

We examined the degree of airway obstruction that developed in eight asthmatics who exercised while breathing air under four conditions: (a) ambient room temperature and water content; (b) body temperature and ambient water content; (c) ambient room temperature fully saturated; and (d) body temperature fully saturated. These test conditions were performed in random order. Multiple aspects of pu...

PURPOSE OF REVIEW Numerous clinically relevant allergenic molecules enhance the performance of specific (s) IgE tests and improve the specificity of allergy diagnosis. This review aimed to summarize our current knowledge of the high-molecular-weight allergens involved in the development of occupational asthma and rhinitis and to critically analyze the contribution of component-resolved diagnosi...

Swimming is generally considered to be a healthy leisure activity for both the young and old. Swimming is even often advised as the most appropriate sport for asthmatic children [1–3], mainly (but probably not solely) on the grounds that inhaling moist air is less conducive to triggering exercise-induced asthma [4]. However, for obvious reasons of microbiological safety, the water of public and...

An episode of exercise induced asthma will usually be followed by a period during which further exercise will not induce asthma. Postulated mechanisms include persistence of catecholamines released during exercise, development of tolerance to released mediators, and mediator depletion. To investigate the underlying mechanism further eight asthmatic men underwent three experimental protocols as ...

objective(s):bone marrow-derived mesenchymal stem cells (bmscs) have attracted significant interest to treat asthma and its complication. in this study, the effects of bmscs on lung pathology and inflammation in an ovalbumin-induced asthma model in mouse were examined. materials and methods:balb/c mice were divided into three groups: control group (animals were not sensitized), asthma group (an...
