[Comparative study of stroke morbidity in Tartu (Estonian SSR) and in Espoo and Kauniainen (Finland)].

The incidence of strokes was studied in Tartu (Estonian SSR) during 1970-1973 and in Espoo-Kauniainen (Finland) during 1972-1973. The study involves only cases of first strokes. According to the standardized data (the population of Finland for 1970 was accepted as a standard) the incidence for strokes in Tartu was 160 cases per year.

[The prognostic value of the lactate concentration and lactate/pyruvate ratio in cerebrospinal fluid following acute cerebral circulatory disorders].

The study was conducted in 80 patients with ischaemic and 29 with haemorrhagic cerebral stroke. Lactate, pyruvate, the lactate/pyruvate ratio and glucose were determined in the arterial blood and lumbar CSF. A high prognostic value of the CSF lactate content was found in cases of ischaemic stroke.
