Les Résultats du Pneumothorax Thérapeutique.

This is a statistical review of the results observed during a period of twelve years in 1,195 patients (service of Dr. Rist). In 817 of this number, pneumothorax was produced; with the other 378, the attempted collapse of the lung was unsuccessful, or the patients refused the treatment. There is no description of the technic employed. The patients treated are arranged in two groups, those nontuberculous and those tuberculous. Among the first mentioned are those with bronchiectasis, gangrene of the lungs, and interlobar or pulmonary abscess. The results among these seem good except with gangrene. With tuberculous patients, pneumothorax favors healing of the pleura. In bilateral tuberculosis, only a small number were benefited. The treatment seems to be helpful when only one lung contains active lesions. Of 534 patients with fibrocaseous tuberculosis, 48 per cent. are well or improved; 17 per cent. are stationary, and 35 per cent. are worse
