[Atypical teratoid/rhabdoid tumors of childhood].

The paper describes 6 cases of atypical teratoid/rhabdoid tumors (ATRT) in the complete absence of classical rhabdoid elements isolated from 25 INI1-negative central nervous system tumors investigated in the period 2006 to the present time. Analysis of the specific features of the histological structure of INI1-negative tumors could identify a few histological types of ATRT according to the conventionally standardized criteria for diagnostic search.

Turcot syndrome. Rare observation and literature review.

The Turcot syndrome is a rare disease which is characterized by a combination of a brain tumor with a y at which the neoplasm of the colon. About 150 of such observations are described in world literature. Our own observation and a literature review are presented in this article.

[Keratin dielectric parameters in the millimeter wavelength range].

The specific density of human hairs, which are known consist essentially of keratin, was measured. Based on the data on the attenuation of millimeter radiowaves in hairs, the dielectric permeability of hairs was determined. Multiple reflections of waves at the boundary of the hair layer were into account.

[Diagnostic thermoradiolocation in neurosurgery].

From the examination of 915 patients with neurosurgical pathology the authors showed the possibility of mediated thermoimaging of localized lesions in the brain, spinal cord, and peripheral nerves. The combination of local and distant thermoasymmetries which are realized through reflex mechanisms of vegetovascular innervation is a characteristic feature of the thermovision syndromes in the infrared wave bands. It was proved experimentally and clinically that radiothermometry in the millimeter and centimeter wave bands yields information on the temperature of the surface and deep-seated cerebral tissues through the hairs on the head.
