[Late complications of poliomyelitis]. / Pozdnie oslozhneniia poliomielita.

We examined 73 31-55-year-old postpoliomyelitis patients who had paralytic form of the disease before the age of 11. It was found that progression of neuro-muscular signs (pareses, atrophies, myalgias), typical for postpoliomyelitis muscular atrophy (PMA) emerged in 43 patients. Classical statistical analysis of clinical and electromyographical data and special statistical method of extreme parameter grouping confirmed PMA only in 8 out of the above 43; 3 forms of postpoliomyelitis syndrome were recognised.

[Importance of analysis of nonspecific activating influences on the cerebral cortex of patients with sequelae of closed cranio-cerebral injuries]. / Znachenie analiza nespetsificheskikh aktiviruiushchikh vliianii na koru mozga u bol'nykh s posledstviiami zadrytoi cherepno-mozgovói travmy.

Clinico-electrophysiological examinations of 10 healthy subjects and 44 patients with sequelae of closed craniocerebral injuries were carried out. The injury sequelae were characterized by subclinical organic symptoms and prevalence of disturbances of CNS general function Changes of electroencephalograms within a frequency range of 8 to 13 Hz (the alpha-range) occurring in the response to a light flash within an interval of 0 to 1 sec were analyzed. Statistically significant correlations between the response character in the alpha-range and the prevailing localization of the injury (the cortex or the trunk structure) were revealed. The informative value of the methods used for analyzing the changes in nonspecific activating effects on the cerebral cortex, as compared to those characteristics of healthy individual is shown. This may be of importance for diagnostic purposes and estimation of patients' working capacity.
