Prophylactic treatment of childhood asthma.

The prophylaxis of childhood asthma is discussed under the headings of prevention by the pregnant mother in avoiding hypersensitizing foods and the adherence to breast feeding, immunotherapy of the child and chemoprophylaxis by sodium cromoglycate or ketotifen fumarate.
