[Effects of fiber bronchoscopy on partial pressure of oxygen in the skin of miners with diseases of respiratory organs]. / Vliianie fibrobronkhoskopii na partsial'noe napriazhenie kisloroda v kozhe u gornorabochikh s patologiei organov dykhaniia.

Influence of fiber bronchoscopy (FBS) on the partial tension of oxygen (pO2) in the skin was studied in 17 respiratory disorders affected miners, with no stable FBS-caused gas exchange disorders established. The patients affected with atrophic endobronchitis actually did not exhibit pO2 changes in response to FBS. In the catarrhal and hypertrophic endobronchitis cases, FBS-related pO2 content decrease was registered with subsequent increase to the initial level 24 hours later, which was explained by bronchial permeability improvements after the FBS procedures.

[Diagnostic errors in silicotuberculosis (clinical-autopsy comparisons)]. / Oshibki v diagnostike silikotuberkuleza (kliniko-sektsionnye sopostavleniia).

Basing on 42 post-mortem examinations of silicotuberculosis cases, the contributors display the most frequently encountered errors in diagnosing this disease. Silicotuberculous bronchadenitis, conglomerate-cirrhotic lower-lobe silicotuberculosis and their complications (e.g. concomitant pericarditis and endobronchitis) are the most difficult cases for detection. To avoid diagnostic errors, a most detailed case history study is needed, along with a complex clinico-functional and tomography examinations, a wide use of endoscopy and bacteriological techniques.

[Bronchoscopic diagnosis of pulmonary tuberculosis in miners]. / Bronkhoskopicheskaia diagnostika tuberkuleza legkikh u gornorabochikh.

Two hundred and thirty nine records of bronchoscopic examination of miners from iron ore mines, including 114 patients with active pulmonary tuberculosis were studied and the frequency of specific and nonspecific endobronchitis and functional, anatomical and hemocirculatory disorders was determined. Qualitative estimation of the endoscopic symptoms and computer-assisted analysis enabled one to validate the direct and probabilistic bronchoscopically evident signs of active tuberculosis. The data on the mature, frequency and diagnostic value of some endoscopic signs should be considered in differentiation of tuberculosis in miners (without pneumoconiosis).
