[Aerogenic risk factors and diagnosis of bauxite pneumoconiosis].

The research purpose is an estimation of influence of the bauxite dust on the state of the bronchopulmonary system of workers. It has been indicated that exposure of the poor fibrogenic dust while the process of the bauxite ore extraction, results in development of pnevmokoniosis characterized by substantial ventilatory and haemodynamic disorders limiting the workability of patients.

[Symptoms of asbestos-related diseases and correction of hemodynamic and ventilation changes in asbestosis patients].

The authors present results of thorough examination of asbestosis and dust bronchitis patients, features of dust load and X-ray functional changes, efficiency of physical therapy complexes in correcting cardio-pulmonary syndrome.

[Features of chronic occupational bronchitis in nonferrous metallurgy workers]. / Osobennosti khronicheskogo professional'nogo bronkhita u rabochikh proizvodstsv tsvetnoi metallurgii.

The authors summarized results of periodic medical examinations and deep clinical studies of metallurgy workers with bronchial and pulmonary disorders. The article covers clinical and functional characteristics of toxic and dust bronchitis, clinical course and manifestations.

[Clinical features of pulmonary diseases caused by chrysotile asbestos dust]. / Klinicheske osobennosti zabolevanii legkikh ot vozdeistviia pyli khrizotil-asbesta.

The authors studied clinical, roentgenologic and functional signs of asbestosis and chronic dust bronchitis in 57 workers engaged into extraction and processing of asbestos. Occupational peripheral lung cancer was revealed in 4 cases. Chronic dust bronchitis appeared to be diagnosed with delay, usually at I-II stages.

[Clinical course of asbestosis under the existing conditions in extraction and processing of serpentine asbestos]. / Klinika i techenie asbestoza v sovremennykh usloviiakh dobychi i pererabotki khrizotil-asbesta.

The authors followed changes in clinical course of asbestosis, comparing groups of individuals working in exposure to chrysotile-asbestos dust, patients having so-called late asbestosis and reference group (individuals with absent or minimal roentgenologic changes in lungs). Analysis of 530 case histories proved increase of average length of service in dusty conditions before asbestosis development, longer progression of pulmonary fibrosis. Asbestosis progression does not depend on medical resolutions. "Late" asbestosis occurs in retired workers who were engaged into auxiliary occupations. Low baseline values of respiratory function and associated respiratory infection worsen the overall prognosis.
