[On results of operative conference of pulmonologists and occupational therapists in St. Petersburg and Leningrad region, concerning the topic "Justifying changes in "Occupational Diseases list" according to respiratory disease classification and global strategies of diagnosis, treatment and prevention of chronic obstructive pulmonary diseases (COLD) and bronchial asthma (GINA)"].

Results of operative conference of North-West Russia pulmonologists and occupational therapists were summarized and covered improvement of current list of occupational diseases. Resolution of the operative conference on the problem is presented.

[Features of occupational fluorosis course]. / Osobennosti techeniia professional'nogo fliuoroza.

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.

[Results of X-ray follow-up in late silicosis]. / Rezul'taty rentgenovskogo nabliudeniia pri pozdnem silikoze.

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.

[Value of x-ray study in diagnosis of occupational diseases]. / Znachenie rentgenologicheskogo issledovaniia v diagnostike professional'nykh zabolevanii.

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 diagnosis of occupational myofibrosis]. / O diagnostike professional'nogo miofibroza.

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 combined action of intermittent vibration and physical loads (exemplified by the grinder-buffers of turbine vanes)]. / Sochetannoe deistvie preryvistoi vibratsii i fizicheskikh nagruzok (na primere shlifovshchikov-polirovshchikov turbinnykh lopatok).

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.

[Occupational lung pathology in gas cutters]. / Professional'naia patologiia legkikh u gazorezchikov.

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.
