Chronic bronchitis in Victoria, New South Wales and Queensland.

A study of chronic bronchitis was carried out on 195 ex-servicemen from Victoria New South Wales and Queensland. Exacerbations of chest symptoms were commonly found and chronic bronchitis was in important cause of haemoptysis. Weather conditions, especially cold weather, affected chest symptoms and early age of starting to smoke affected the incidence of severe bronchitis. The clinical profiles of the cases studied were similar to those in some of the reports from Canada and Britain.
