[The characteristics of cryptosporidiosis epidemiology in the European part of Russia]. / Osobennosti épidemiologii kriptosporidioza v Evropeiskoi chasti Rossii.

Large-scale surveys of representative population groups (n = 2243) in 7 cities and 3 provinces of the central, Povolzh'e, and northwestern regions of the Russian Federation provided the basic epidemiological features of cryptosporidiosis in the European part of the country. Its mean incidence of the population was 3.34%, much higher in children (3.69%) than in adults (0.41%). The boys were more frequently afflicted than the girls (4.69% versus 1.92%). There were no differences in the infection rates between rural and urban children. Young children (aged 1-3 years) with diarrhea and children in closed collective bodies are infection risk groups. The detection rate of persons infected with Cryptosporidium was much greater by the formalin-ether precipitation technique than that by the routine smear test. The correlation coefficient as to the infection rates detected by the routine smear tests was 1.75.

[Erythrocyte sedimentation rate in clinical practice]. / Skorost' osedaniia éritrotsitov v klinicheskoi praktike.

Describes the principal mechanisms of red cell sedimentation rate in accordance with the available literature data. Characterizes the factors enhancing and inhibiting red cell sedimentation rate. Presents three methods for evaluation of red cell sedimentation rate: Panchenkov's micromethod, rapid method, and fractionated test. Discusses the most incident errors occurring in determination of red cell sedimentation rate and the clinico-diagnostic significance of this parameter in a number of diseases.

[The prevalence of cryptosporidiosis among the city population of Russia and Belarus]. / Rasprostranenie kriptosporidioza sredi naseleniia nekotorykh gorodov Rossii i Belarusi.

A total of 248 adults (170 with somatic diseases and 78 with the diarrheal syndrome) and 1206 children (323 attending kindergartens, 231 with somatic diseases, and 652 with the diarrheal syndrome), residents of seven towns of Russia and Belarus, were examined for cryptosporidiosis in 1989-1992. The mean infection rate of children and adults with the diarrheal syndrome was 4.8 and 2.7%, respectively, of those with somatic diseases 2.6 and 0% respectively, and of healthy children 1.9%. Children living in the towns of Belarus, localized in the radiation contamination zone, were more frequently infected than children living in other towns. The towns of the European Russia and Belarus should be regarded as stable foci of cryptosporidiosis infection.
