[Clinical and radiologic characteristics of undeveloped lung in children].

Lung underdevelopment was detected in 60 of the 2487 children aged 1 to 17 with the clinical picture of recurrent bronchitis. Seven patients presented with aplasia and agenesia of the lung or its part, ten with cystous hypoplasia, eight with common hypoplasia, and thirty-five with acquired form of the respiratory system underdevelopment. The efficacies of various methods of radiodiagnosis in underdevelopment of the vessels, bronchi, and the respiratory sections varied.

[Current bronchological methods of diagnosis of lung cancer].

On the basis of an analysis of results of studying 541 patients with lung cancer the authors consider that bronchoscopy can diagnose the central lung cancer practically in all the patients including the early stages of the disease before the development of changes in the lungs on roentgenograms. The histological verification of the peripheral lung cancer of the root and median zones is ensured in 77% of patients by bronchofibroscopy under local anesthesia with the transbronchial peripheral forcepts and brush biopsy under the roentgen and TV control. Bronchological diagnosis of cancer of the subpleural zone still remains less effective.
