Allergen exposure plays a major role in the development of sensitization, inflammation and symptomatic asthma. The development of new means of detecting allergens has enabled the evaluation of the effect of a reduction in allergen exposure to be better assessed. In order to prevent allergen exposure it is necessary to determine the allergen sources and reservoirs to which avoidance measures sho...

Long-term change in nonspecific and specific bronchial hyperresponsiveness was studied in 16 subjects with asthma induced by toluene diisocyanate (TDI). A significant positive correlation between months of follow-up and provocative dose inducing a 20 percent fall in FEV1 (PD20FEV1) methacholine was observed in 5 of 16 subjects. In 4 of these 5 subjects, a PD20FEV1 > 1 mg of methacholine was obs...

BACKGROUND In hospital clinics exercise challenge is used as a simple, non-invasive, non-pharmacological test for asthma in childhood. Little is known of its value in a community setting. An exercise test was therefore evaluated as an adjunct to a respiratory questionnaire in the course of an asthma survey. METHODS From a cohort of 4003 primary school children, 607 of 799 with respiratory sym...

Little is known about the relation of bronchial responsiveness (BHR) to sensitization to individual allergens, or its variation between countries. Data were obtained for BHR, specific immunoglobulin E and confounding variables from 11,215 subjects, aged 20-44 yrs at the start of the European Community Respiratory Health Survey, in 34 centres in 15 countries. The relation of BHR to sensitization...

Cough is a common symptom of respiratory diseases associated with irritation or inflammation of the airways, and symptomatic antitussive drugs are frequently prescribed to control an abnormal cough reflex. Our aim was to evaluate the effects of moguisteine, a novel, peripheral, nonnarcotic antitussive agent, on airway inflammation induced in guinea-pigs with a variety of stimuli. These stimuli ...

Exercise and eucapnic hyperventilation with cold air can produce bronchoconstriction in asthmatic subjects, but their enhancement of nonspecific bronchial reactivity remains unclear. We studied the effect of submaximal exercise and cold air exposure on bronchial reactivity to methacholine in a normal control group (n = 10) and in subjects with bronchial asthma (n = 17). Bronchial provocation te...

There is evidence that a link exists between the upper and lower respiratory tracts. During the last fifty years many clinical observations has lead to a new pathogenic view of rhinosinusitis and asthma defined as Sinobronchial Syndrome. The inflammatory process in the nose and bronchi explains some of the complex interactions among different clinical diseases, such as rhinosinusitis, asthma, b...

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 ...

I y the past we have perfor~iiecl cliagnostic bronchoscopy on a group of paraplegic patients in whom the induction of topical anesthesia in the usual way was clifficult. For these patients, a method of applying local anesthesia mas developed which was so effective and silnple that i t has become our prcferred technique in the preparation of all adult patients for endoscopy or hronchography. Ane...
