OBJECTIVE Pregnancy-induced hypertension is an important cause of maternal mortality, intrauterine growth retardation, and perinatal mortality. We examined the relationship between pregnancy-induced hypertension and asthma. STUDY DESIGN The study population consisted of 24,115 women without a history of chronic systemic hypertension who were delivered of live born and stillborn infants at Mou...

The contribution of vagal mechanisms to exercise-induced asthma has been studied in 10 adult asthmatic patients using the anticholinergic drug ipratropium bromide. Exercise tests were performed for eight minutes on a cycle ergometer and each individual's tests were standardised by matching oxygen uptake. Two tests were done on each of three study days, the first being without previous medicatio...

The airway responses to histamine, exercise and ultrasonically nebulized hypertonic saline have been compared in ten asthmatic patients. The responses to hypertonic saline were not significantly different when the same volume of aerosol was given in a single dose or in 10 l aliquots, suggesting that the challenge is cumulative. The variability of the response to hypertonic saline challenge was ...

We report the cases of three subjects who developed asthma after being exposed to formaldehyde dust or gas. For two subjects, specific bronchial provocation tests with formaldehyde gas did not cause significant bronchoconstriction, whereas exposure to formaldehyde resin dust did. One subject experienced asthmatic reaction after being exposed to formaldehyde resin dust and gas. These findings su...

BACKGROUND Cardiovascular disease (CVD) is a common comorbidity in people with asthma. However, safety concerns have caused heterogeneity in clinical guideline recommendations over the use of cardioselective beta-blockers in people with asthma and CVD, partly because risk in the general population has been poorly quantified. The aim of this study was to measure the risk of asthma exacerbations ...

The short-term protective effect on exercise-induced asthma (EIA) and the duration of action of formoterol, given by metered dose aerosol at a dose of 24 micrograms, were compared with salbutamol (200 micrograms) and placebo in twelve asthmatic EIA-positive patients in a double-blind, placebo-controlled, three period cross-over study. On each treatment day the patients were given one of the dru...

BACKGROUND Asthma is a common illness, especially among children. Exercise-induced asthma is an important consideration, both as a factor, limiting physical activity of patients, and also as an indicator of poor long term control. We investigated pre-Valence of exercise-induced asthma in a group of asthmatic children living in southern Iran. METHODS We conducted treadmill exercise challenge t...

Research into occupational asthma (OA) in Japan has been led by the Japanese Society of Occupational and Environmental Allergy. The first report about allergic OA identified konjac asthma. After that, many kinds of OA have been reported. Cases of some types of OA, such as konjac asthma and sea squirt asthma, have been dramatically reduced by the efforts of medical personnel. Recently, with the ...

BISCIONE et al. [1] reported a significant association of upper airway Chlamydophila pneumoniae RT-PCR positivity in atopic asthmatics (cumulative rate 22%) compared with nonatopic nonasthmatic spouses (9%). In the discussion, BISCIONE et al. [1] argued in favour of acute, rather than chronic, infection as the explanation for their observation that detection was mostly intermittent rather than ...
