title: Pulmonary tuberculosis. An occupational hazard for pathologists and pathology technicians in Japan.
abstract: The incidence of pulmonary tuberculosis among pathology workers in Japan is elevated, presumably due to frequent exposure to tubercle bacilli in the work place. To demonstrate the etiological significance of the association between this disease and occupation epidemiologically, a questionnaire survey was performed to assess the incidence of pulmonary tuberculosis among 1,201 pathologists and 1,187 pathology technicians throughout Japan. Pathology department workers other than pathologists and technicians, such as secretaries (n = 207), and workers in university departments of preventive medicine and public health (n = 732) served as control groups. While non-occupation-related tuberculosis was found in both departmental groups with nearly equal incidence, the incidence of pulmonary tuberculosis among pathologists and pathology technicians after engagement in their current specialist work was significantly higher than that in the control groups (odds ratio = 6.08-10.98). The incidence of disease among pathology technicians who assisted in autopsies was markedly higher than among those not involved in autopsies (odds ratio = 6.65). This elevated incidence was significantly related to the duration of work in pathology activities, and showed little change over the last decade. These findings indicate that specific environmental conditions in pathology departments, particularly autopsy of cadavers harboring active tuberculosis, constitute a serious occupational hazard.
