Evaluation of health risk in industrial workers.

The article presents results of evaluating chronic intoxication risks, acute toxic effects risk, carcinogenic risk and risk of occupational diseases due to dust. Findings are that the highest risk levels for chronic intoxication and carciongenic risk are seen in coal open cast miners. The most dangerous occupation is diesel locomotive operator. High risk of occupational disease due to dust is seen in electric steel-making, rail and structural steel production. The most dangerous occupations are electric furnace melters, melter assistants, crane operators, hot rolling operators, metal heaters. The authors revealed chemicall pollutants making maximal contribution into formation of health risk for workers.

[Rotaviruses in younger children in Novosibirsk in 2005-2007: detection and genotyping].

Examination of 1898 patients with acute enteric infection from March 2005 to February 2007 showed that group A rotaviruses were the most frequent cause (35%) of acute gastroenteritis among children under 3 years of age. Majority of cases of rotavirus infection was detected in infants under 1 year of age (71.8%). The peak of sporadic incidence was observed between February and May. High rate of mixed infection (45.6%) was observed - associations of rotaviruses with other viruses (noroviruses, astroviruses) and bacteria (Salmonella, Shigella, enteroinvasive Escherichia coli, Campylobacter, and opportunistic species) were detected. P- and G-genotypes of 337(50.8%) isolates of group A rotaviruses were determined by RT-PCR. The most prevalent strain was P[8]G1 (54.6%) followed by P[8]G3 (10.7%), P[8]G9 (8.6%), P[4]G2 (8.3%), and P[8]G4 (4.5%) genotypes.
