[Differential diagnosis of infiltrative tuberculosis and pneumonia located in the the lower lobe]. / Differentsial'naia diagnostika infil'trativnogo tuberculeza i pnevmonii pri ikh nizhnedolevoi lokalizatsii.

Differential diagnosis was made in 2 groups of 85 patients with infiltrative tuberculosis and pneumonia. Clinical, laboratory and x-ray findings confirmed the value of standard examinations (anamnesis, complaints, physical and laboratory methods). Tuberculin diagnosis confirms the primary diagnosis only in case of hyperergic response to the Mantoux test with tuberculin PPD 2 TU. Tracheobronchoscopic detection of nonspecific endobronchitis is not a reliable enough diagnostic criterion to differentiate between tuberculosis and pneumonia. Roentgenologically, tuberculosis is characterized by more frequent polysegmentary lesions and involvement of the VI segment, pneumonia by involvement of the middle lobe, segments VIII and X.

[Characteristics of the clinical manifestations of inactive pulmonary coniotuberculosis]. / Osobennosti klinicheskikh proiavlenii neaktivnogo koniotuberkuleza legkikh.

Analysis of clinical development of nonactive coniotuberculosis in 167 patients showed that pneumoconiosis, complicated by tuberculosis, grew progressively worse as to its stage, form and incidence. Intoxication syndrome in such patients was of specific tuberculosis character and the above patients could be quite efficiently treated by antituberculosis preparations.

[Pathomorphosis of coniotuberculosis]. / Patomorfoz koniotuberkuleza.

Changes in the epidemiology, morphology and clinical picture of active anthracotic tuberculosis within the last 20 years referred to an increase in the average age of the patients and the length of service under dust conditions. Among the patients with anthracotic tuberculosis the number of drufters increased while the number of coal cutters and breakage face workers decreased. There was observed a rise in the proportion of infiltrative tuberculosis and tuberculomas of the lungs with a simultaneous decrease in the proportion of fibrocavernous tuberculosis. At present the process of active anthracotic tuberculosis is more favourable. The percentage of extended forms of anthracotic tuberculosis decreased.
