Chronic Bronchitis? Pulmonary Emphysema?
Chronic Bronchitis? Pulmonary Emphysema? is a scholarly work, published in 1961 in ''JAMA Internal Medicine''. The main subjects of the publication include pulmonary emphysema, incidence, medicine, disease, pleural disease, respiratory disease, chronic obstructive pulmonary disease, internal medicine, bronchitis, and intensive care medicine. Does this discrepancy represent a real national difference in incidence of disease or is the problem one of definition?
