In the result of the analysis of irradiation doses of 36,895 servicemen who have participated in liquidation of the Chernobyl APC disaster consequences it was found out that the average radiation dose was 12.1 cSv in 1986, 8.4 cSv in 1987, and in 1988-90 it didn't exceed 5 cSv. The irradiation received by these servicemen has depended on the time of their arrival to the zone of the disaster, the maximum permissible doses of radiation established at that period, the character of their activities and the place of their work, utilization of protection means. A conclusion was made that irradiation dose itself could be considered only as a general guide reference, because it didn't take into consideration internal irradiation and beta-irradiation of skin. That's why it is necessary to continue the further monitoring over the health status of liquidators independently of the doses of irradiation which were fixed in their histories.
Over the period 1983-1985, investigators from the Institute of Hygiene and Epidemiology, Prague, and the Central Research Institute of Epidemiology, USSR Ministry of Public Health, Moscow, carried out a joint study of drug resistance in S. aureus strains in relation to their enterotoxigenic properties and phage group specificity. Altogether 277 strains were explored which had been isolated at random from the clinical material from infant and adult inpatients. Most of the isolated strains featured multiple resistance to antibiotics: PNC (77.9%), CMP (52.7%), TET (21.6%), ERY (17.6%) and LIN (11.9%). The strains isolated from infants were most frequently resistant to TET and ERY. No correlation was found between the incidence of antimicrobial drugs resistance and toxigenic properties of the isolated strains.
In 1984 an Occupational Pathology Center for 30 patients opened in Tchuvash Republic; since 1989 the Center was given a right to certify primary diagnosis of an occupational disease. Occupational morbidity structure in Tchuvash Republic corresponds to that in Russia, but the morbidity level in Tchuvash Republic is slightly lower than that in Russia. The Occupational Pathology Center in Tchuvash Republic served as an object of experiments in elaboration of occupational regulation parameters.
Altogether 3875 women aged 30 to 50 engaged in the textile industry, were examined. Primary prevalence of arterial hypertension was 7.0-7.2%. The implementation of a special program of active prophylaxis resulted in a significant rise of the number of effectively treated patients as compared to the control group.
Pyocinovar and serovar characteristics of 91 P.aeruginosa strains isolated from patients and the environment in a hospital for premature children, a child survey hospital and a neonatological hospital. The leading epidemiological markers of P.aeruginosa strains, among them pyocinovar 883722, serovar 6 (a hospital for premature children), pyocinovar 888888, serovar 4 (a child surgery hospital), pyocinovars 888888 and 861322 (a neonatological hospital).
Having analyzed the data base of All-Army register contained information about 35,970 rescuers it was determined that 45.5% of them during works in dangerous radiative conditions complained of the health change for the worse characterized by the state of irritation of mucous membrane of superior respiratory and gastrointestinal tracts. The direct correlation between value of irradiation dose and frequency of complaints, and also degree of lowering of there physical performance have been defined.
The production of toxins of the toxic shock syndrome and enterotoxins by S. aureus of clinical origin was studied by means of commercial standard antisera and standard toxins. The study revealed that among 511 strains isolated in Russia toxigenic ones constituted 41%, and among 592 strains isolated in Czechia toxigenic ones constituted 63%. The capacity for producing toxins may be used as an epidemiological marker.
The article represents results of time-matched follow-up of population residing in Myslets settlement that appeared in railway accident zone with significant phenol and oil products spread. Various health disorders diagnosed in the residents in 4 months after the accident appeared not specific, according to thorough studies by Nizhny Novgorod Research Institute for Hygiene and Occupational diseases, by RAMSc Clinic for Occupational Medicine. The authors demonstrate leading role of occupational pathology center in medical care for people in disaster zone, role of occupational therapist. Other emphasis is put on technogenous stress importance in conflict situations.
