[Epidemiologic analysis of the report "Non-specific intestinal diseases" (Slovakia 1975-1989)]. / Epidemiologická analýza "Blizsie neurcených crevných ochorení" (Slovensko 1975-1989).

The authors submit an analysis of the notified morbidity, the number of deaths and work incapacity on account of "non-specified intestinal diseases" ("009") in Slovakia in 1975-1989. They focus attention on the age distribution and seasonal incidence of these diseases. During the investigation period 27,075 cases were reported and the morbidity has a rising trend. The most severely affected age group are infants where the death rate is highest. The authors found a marked disproportion between the number of notified diseases and the work incapacity on account of "009", which accounts for 2/3 of all work incapacities on account of intestinal infections.

[Occurrence of rotavirus RNA electropherotypes in the pediatric population in Slovakia]. / Výskyt RNA elektroforetypov rotavírusov cirkulujúcich v detskej populáchii SSR.

Using the method of electrophoresis in polyacrylamide gel (PAGE), the authors assessed electropherotypes of rotavirus RNA in extracts of 119 specimens of faeces of sick children and from neonates with asymptomatic rotavirus infection. In both investigated groups they detected electropherotypes of five profiles: of these three had the nature of "long" electropherotypes and were detected in 91.6% of the tested samples. In the group of sick children they recorded circulation of four electropherotypes with exchange of the dominant type of electropherotype after a three-year interval. In the group of healthy neonates they detected in the course of 21 months the same electropherotype, which was not detected in the group of sick children throughout the period of investigation. The identity of RNA profiles of strains from neonates was confirmed by co-electrophoresis.
