BRONCHIAL ASTHMA IN ADULTS-Causes and Treatment.

Food and inhalant allergens were of about equal importance in producing bronchial asthma in 907 adults between the ages of 15 and 55 years.Drug and especially bacterial allergens were infrequent causes.Psychogenic factors may activate or exaggerate causes mentioned but were not the sole cause of any case in this series. Food allergens are best studied and controlled by the standardized cereal-free elimination diet and at times other elimination diets. Test-negative diets usually fail because of the fallibility of both negative and positive skin tests. Inhalant allergy is controlled by the elimination of causative allergens by varying degrees of environmental control and often by pollen and dust filters in the window. Desensitization is necessary against those allergens that cannot be removed from the environment. Dilutions in the millions and billions may be required. Morphine and other opiates, Demerol, chloral, paraldehyde and large or moderate doses of barbiturates are contraindicated in bronchial asthma, as emphasized by deaths resulting from the use of them. Bronchoscopy is indicated for bronchial obstruction due to inspissated mucous plugs, but the danger of the procedure, especially with much sedation, must be recognized. When secondary infection is probable, the use of sulfadiazine, penicillin, aureomycin and chloramphenicol must be considered.
