16. Non-tuberculous Abscess of the Lung. Etiology, Treatment, and Results in 90 Cases.

Elliott C. Cutler and Robert E. Gross, Boston.

(By Invitation)

Abst. The paper is a summary of 90 cases on the Medical and Surgical services of the Peter Bent Brigham Hospital during a 20-year interval, from 1914 to 1934. 95% of the cases have been followed for periods varying from 2 to 22 years. 46 of the 90 patients developed an abscess as a direct result of an operation. 13 of the cases developed a complicating empyema or pyopneumothorax with a mortality of 54% as compared to 35% in those who did not have the complication. 47 cases received surgical treatment with 42% mortality. 43 cases received only medical treatment with a mortality of 33%. In analyzing the cases in this report the present-day views regarding the development and treatment of pulmonary abscess is summarized.

17. The Treatment of Lung Abscess, Including an Analysis of 100 Consecutive Cases.

C. I. Allen, Detroit.

Abst. The various forms of treatment are evaluated. These include the use of postural drainage, evacuation through a bronchoscope, artificial pneumothorax, injections of neo arsphenamine, phrenic nerve operations, and open drainage by the two-stage operation. Composite charts of published series of cases are included to further aid in evaluating forms of treatment.

18. Four Cases of Resection of Calcified Pulmonary Abscess Simulating Tumor.

Evarts A. Graham and J. J. Singer, St. Louis.

Abst. "We have had four patients with cough and expectoration of purulent sputum who have presented what seems to be a hitherto undescribed condition. These patients on x-ray examination showed definite evidence of a pulmonary tumor. In all four cases the removal of the tumor-like mass with different amounts of lung tissue around the mass has resulted in complete relief of the patient's symptoms. In three of the cases there was Extensive calcification with a collection of pus in the center of the mass, and in the fourth case calcification was in progress but had not advanced to the same extent as in the other three cases. A discussion of the pathogenesis of the condition will be given together with remarks on the diagnosis and points in treatment."

19. Suppurative Mediastinitis.

Harold Neuhof, New York.

Abst. The lesion is not as uncommon as is generally assumed. Occasionally the first intimation of its existence is gained at autopsy. The cases on which the presentation is based all revealed well localized lesions. The prompt recognition of the existence of the lesion is the crux of the situation. Operation is indicated urgently as soon as the diagnosis is made. Cure can be achieved even when the patient is desperately sick. Operative technique and results are presented.
