of Allergy and Immunology is both important and timely. Using a validated questionnaire of respiratory symptoms and medication use, the authors examined the prevalence of asthma in a nationwide Japanese population of nearly 23,000 individuals. Stratifying the results by body mass index (BMI), and using logistic regression analysis to adjust for the effects of age, smoking status, allergic rhini...

Thunderstorm outflows preceding epidemics of asthma during spring and summer.

BACKGROUND A study was undertaken to assess the importance of thunderstorms as a cause of epidemics of asthma exacerbations and to investigate the underlying mechanism. METHODS A case control study was performed in six towns in south eastern Australia. Epidemic case days (n = 48) and a random sample of control days (n = 191) were identified by reference to the difference between the observed ...

Barcelona's asthma epidemics: clinical aspects and intriguing findings.

Acute asthma epidemics, weather and pollen in England, 1987-1994.

Recent epidemics of acute asthma have caused speculation that, if their causes were known, early warnings might be feasible. In particular, some epidemics seemed to be associated with thunderstorms. We wondered what risk factors predicting epidemics could be identified. Daily asthma admissions counts during 1987-1994, for two age groups (0-14 yrs and > or = 15 yrs), were measured using the Hosp...
