| Popis: | In a recent paper we1reviewed the problem of calcification occurring in the chests of persons who are insensitive to tuberculin. At that time we outlined the clinical and epidemiologic evidence for suspecting a benign form of histoplasmosis or some other biologically related infection to be the cause of this phenomenon. These studies have been undertaken in order to throw light on certain clinical observations that there exists in many sections of the United States a prevalence of pulmonary calcification far in excess of that which can be explained on the basis of tuberculosis as revealed by tuberculin cutaneous testing. In the past twenty years there has been an increasing interest in this subject, and there have appeared a number of papers which show a consistent discrepancy between the tuberculin tests and the prevalence of pulmonary calcification. In these papers 27 to 83 per cent of young persons were |
