ABSTRACT
Results of clinico-functional examination of workers of metallurgical plants confirmed early development and severe course of chronic bronchitis in this category of workers. The polyetiological aspect of chronic bronchitis is suggested. Changes of the pleura and pneumosclerosis which often accompany chronic bronchitis impede the differential diagnosis with interstitial form of pneumoconiosis. Diagnostic criteria of chronic bronchitis in metallurgists should be determined with consideration of concrete working conditions, endogenous factors of risk in the development of the disease and possible variants of the course.

The extension and pathogenetic role of pleural changes in the development of unspecific chronic pulmonary diseases in 146 workers of different professional groups suffering of chronic bronchitis, were investigated. Ultrasonography and roentgenography were used. The functional state of the lungs was evaluated by means of spirographic and radiological methods. It is concluded that pleural changes are an endogenous risk factor in the development of chronic unspecific pulmonary diseases.

To specify ultrasonography potentialities in differential diagnosis of pleural exudates, 71 patients with exudative pleurisy varying in etiology have been examined. Characteristic aspects of ultrasonic pattern were determined for exudates of different origin. Ultrasonography proved an adequate diagnostic tool in differentiating pleural exudates.
