In the program of research into the natural history of coalworkers' pneumoconiosis now being carried out in Great Britain, emphasis is being put upon the importance of sharpening and validating means for early diagnosis, and upon the need for follow-up studies upon properly selected population samples. Existing information from morbidity and mortality figures from chronic bronchitis and emphysema in Great Britain suggests that atmosphere pollutants are important etiological factors. A parallel is drawn between the course of events in pneumoconiosis, in which dust retention in the lungs does not greatly disable until complicated by tuberculous infection, and a hypothesis that bronchitis is a hypersecretion of bronchial mucus caused by atmospheric irritants and does not disable but encourages secondary infection which may cause emphysema. This hypothesis requires testing by follow-up studies of population samples exposed to various environmental influences. It is suggested that in order to bring this common and disabling disease under control, clinicians must widen their interests beyond the confines of the hospital walls.
