Analysis of X-ray signs in 397 patients suffering from fluorosis revealed degenerative and dystrophic lumbar disorders in 94%, calcified anterior longitudinal ligament in 65%, various changes (epicondylosis, periarthrosis and arthrosis deformans) in 91%. Locomotory disorders appeared systemic, multiple and symmetrical.
The authors present clinical and X-ray data of 30 patients with "late silicosis" that occurred in 5-20 years after they had retired from dust-related occupation. Follow-up over 4-25 years demonstrated progression of nodular pneumosclerosis up to macronodular forms or silicotuberculoma formation. The diseases mostly developed gradually, usually was diagnosed by casual X-ray examination and was long considered as tuberculosis, sarcoidosis or other disseminated lesion.

X-ray studies play major role in diagnosis of such occupational problems as pneumoconioses and locomotory disorders. Diagnostic information obtained by contemporary imaging methods (CT, US, studies with contrast media, etc.) should be considered only addition to data of classical X-ray study with consideration of specific sanitary and hygienic work conditions.
The studies proved that ultrasound and enhanced roentgenomyography are diagnostic methods of choice for occupational myofibrosis, detecting the lesions as well as their extent and severity. Comparing diagnostic value of clinical and radiologic methods proved the latter to disclose early signs of the disease.
The article presents hygienic evaluation of interrupted vibration in grinding of turbine vanes by stationary machines with consideration of static and dynamic load. Criteria estimating the operation are set, clinical features of the occupational diseases are determined.
The authors provide the results of clinical, x-ray, functional and specific allergological examinations made in 396 cutters. Characterize the main forms of occupational respiratory pathology--pneumoconiosis and chronic bronchitis. Haptene metals (chromium, nickel, manganese) contained by the industrial aerosol were established to produce a sensitizing action on the body. The data obtained may be of importance for the diagnosis and prevention of occupational diseases in cutters, expert medical evaluation of the working capacity and follow-up of the patients.
