This issue of the British Medical Bulletin illustrates in a convincing manner the wide scope of modern epidemiology in the study of current medical problems. The topics covered range from such common conditions as hypertension and chronic respiratory disease to such rare diseases as congenital esophageal atresia. It covers studies concerned with functional psychoses and the development of intelligence as well as the more somatic disorders, and extends the scope of epidemiology beyond the study of disease and its causes to the study of the various aspects of health services including screening procedures and the unwanted effects of medications.
In each case, given the limited space and time available to cover a wide area, the authors have wisely decided not to attempt any encyclopedic or superficial treatment of the subject but rather to concentrate on the areas of controversy and current uncertainty. The results are a series of well written concise condensations of the points of current interest in each field.
