[Study on the pulmonary tuberculosis in the elderly]

A study was made for 13 cases of patients over 80 years of age who received medical treatment for tuberculosis. Four factors of onset of tuberculosis at old age were indicated. 1. No opportunity for examination of X-ray for old generation. 2. Atypical shadows on the chest X-ray film. 3. Low stress tolerance. 4. Exacerbation of old tuberculosis during the treatment of other diseases. The results suggest the possibility of increasing pulmonary tuberculosis among the elderly persons in the near future.
