Lack of clinical exacerbations in adults with chronic asthma after immunization with killed influenza virus.

The effects of immunization with killed influenza virus vaccine were assessed by comparison with placebo in a double-blind study of 318 adult patients with chronic asthma. The patients were randomly allocated to active vaccine and placebo. No difference was observed in peak expiratory flow rate or in clinical symptoms of bronchial obstruction between the groups receiving active vaccine and placebo during the first week after immunization.

Theophylline plus hydroxyzine versus theophylline monohydrate in the treatment of asthma.

The efficacy of 281.7 mg of theophylline monohydrate and a combination of theophylline (240 mg) + hydroxyzine (7.5 mg) were compared in a double-blind, crossover, placebo-controlled study in 15 patients with chronic reversible bronchial asthma.

Further decrease in thyroidal uptake and disappearance of endemic goitre in children after 30 years of iodine prophylaxis in the east of Finland.

Endemic goitre of moderate severity was mainly found in the east of Finland in the 1930's. Studies in the 1950's showed an average daily iodine intake of 65-70 micrograms in the west and 50-65 micrograms in the east of the country. The use of iodized salt was introduced in the late 1940's but added only 15 micrograms of iodine to the daily intake.
