Complex clinical examination of patients with occupational hypersensitivity pneumonitis caused by inorganic, organic and mixed dust helped to spicify variants of the disease--with prevailing bronchial asthma, chronic obstructive bronchitis, recurrent pneumonia, chronic respiratory failure.
For understanding up-to-date situation with fibrosis caused by chrysotile-asbestos, the authors conducted X-ray and hygienic studies in 2 enterprises extracting and enriching asbestos--"Tuvaasbest" JSC and "Orenbourgasbest" JSC. Authors followed correlation between diffuse pulmonary changes and length of service, dust load and cumulative exposure dose of respirable fibers. The strongest correlation was demonstrated for dust load. Workers engaged into up-to-date industry extracting and enriching asbestos are diagnosed as having indistinct and moderate roentgenologic types of fibrosis. Examples of dose-effect dependence prove dust load to be informative and expedient integral parameter for hygienic regulation and evaluation of asbestos-containing dust and industrial aerosols doses.
The article covers general principles of health care for workers in various industries associated with contact to dust containing asbestos. The authors present main requirements of legal papers basing concepts that determine role of employers, trade unions, workers and medical officers in creation and maintenance of safe work conditions, in establishment of prophylactic, therapeutic and rehabilitation measures.
The article summarizes studies carried in RAMSc Research Institute for Occupational Medicine on chrysotile asbestos. Not denying potential carcinogenicity characteristic for all kinds of asbestos, those studies stress low biologic aggression of chrysotile asbestos during occupational exposure, even if the excessive MAC is demonstrated formerly in asbestos industry enterprises. Work with chrysotile asbestos, as every one in mining industry, requires not ban, but accomplishment of proper measures aimed to prevent pneumoconiosis and dust bronchitis. The article demonstrates unique experience of Russian scientists--evaluation of exposure to chrysotile without admixtures and amphibole additives. The authors define prospective research trends that, if being international, could correctly solve problems associated with further use of chrysotile asbestos, rising no "anti-asbestos" boom.
The article deals with analysis of scientific data concerning etiology, pathogenesis, clinical and roentgenologic manifestations, morphologic appearances and other aspects to precise and refine the former idea of pneumoconioses. The authors present the main principles for improved classification of pneumoconioses.
