[Factors influencing morbidity rates in preschool children in the city of Orsk].

The comparative contribution of environmental factors to morbidity among the preschoolchildren of the town of Orsk was studied by applying currently available methods. Great morbidity is favoured by toxicosis during maternal second-half pregnancy, the poor health status of neonatal babies at birth and by the end of the first year of life, going to the nurseries where vegetable and calorie diets are not observed, the location of kindergartens in the areas with high traffic, high ambient air pollution with sulfuric anhydride and acid, and with substandard drinking water quality. Lower morbidity in children is in turn promoted by greater quantities of vegetables and fruits in the meals both at home and in the nurseries and kindergartens, over 2-month breast feeding, no adverse working conditions in their parents, as well as implementation of conditioning procedures in children.

[The significance of variation pulsometry in the diagnosis of ischemic heart disease during mass screening of the population].

The use of computerized heart rhythm assessment in diagnosis of patients at high risk of ischemic heart disease during epidemiological surveys is discussed. The method has been shown to be of value in detection of ischemic heart lesions developing in menopausal women. The method can be used to monitor patients in the course of long-term follow-up.
