[Neurinomas of the acoustic nerve in childhood and adolescence].

The specific features of neurinoma of the auditory nerve were analysed clinically in 21 patients whose ages ranged from 12 to 18 years. Neurinoma of the auditory nerve located in the cerebellopontine area in children and adolescents has some specific features distinguishing it from that in adults. For instance, its incidence among boys is the same as that among girls.

[Clinico-electrophysiologic analysis of the results of surgical treatment of focal epilepsy in children].

The authors analyzed the electroclinical data obtained in the surgical treatment by the open method of 104 children and adolescents with focal and multifocal epilepsy. The indications were frequent epileptic seizures, resistance to drug therapy, clear-cut clinical and electrophysiological correlations with regard to the localization of the epileptic focus. If nonoperative treatment has no effect, it is not advisable to delay surgical intervention by more than 1--2 years.

[Topography of the optic thalamus, caudate and lenticular nuclei of the human brain in frontal section (an anatomical-statistical study applied to stereotaxis)].

Topographic coordinates of the thalamus, caudate and lentiform nuclei of the human brain in relation to the medial-sagittal plane and inferior-medial part of the corpus callosum were studied in 70 preparations. The parameters under study are characterized by mean values of the variants and square deviations. Detailed tables of these values are given which may be employed in stereotaxical calculations for all coordinates, for men and women separately, for the right and left hemispheres, brachy- and mesencephaly.
