A survey was made on the newly registered tuberculosis patients during the period from January 1 to December 31, 1972, regarding their background factors, severity of disease, extent of bacteriological examinations and the mode of detection. In 1972, 148 cases of pulmonary tuber culosis were registered at the Nagano Health Centre, and among them, 113 were newly registered cases and the remaining 35 were relapsed cases. The results were summarized as follows:<BR>a. Newly registered patients.<BR>1) The proportion of children below 15 was 29%, which was higher than the national average (9%). This is explained by the fact that many primary infection cases are registered as active tuberculosis in this age group, and these cases should be differentiated into 2 categories in the future.<BR>2) Observing by the type of lesions, cavitary tuberculosis occupied 25%, non-cavitary lesions 67%, and others 8%.<BR>3) Bacteriological examinations were carried out in 59%, and the bacilli positivity was 24%. The bacilli positivity was 52% for cavitary tuberculosis and 8% for non-cavitary tuberculosis.<BR>4) As to the mode of detection, 26% were found by MMR, 72% by symptomatic visit to physicians and 2% by others. In 1969, 37% of new patients were detected by MMR, and the detection rate was 0. 14% to those examined by MMR. Both the proportion of cases found by MMR and the detection rate of MMR have been decreasing, and they were 26% and 0.06%, respectively, in 1971.<BR>5) Out of whole cases, 78% were examined by MMR within 3 years, and 67% were diagnosed as healthy, 11% were refered to detailed examinations and finally diagnosed as healed. Among 76 cases diagnosed as healthy within 3 years, 16 (21%) developed cavitary tuberculosis, and these cases are considered as rapid cases.<BR>b. Relapsed cases.<BR>1) Relapsed cases occupied 24% of registered cases in 1972. The bacteriological examinations were carried out in 86%, and the bacilli positivity was 20%.<BR>2) As to the mode of detection, 26% were found by MMR and 74% by symptomatic visit to physicians. Relapses were found even among cases with old history of tuberculosis before 1955, and the fact indicates the necessity of inviting cured cases including cases omitted from the register to the periodical follow-up.
