[Basilar skull fractures: clinical and prognostic aspects].

The incidence of basilar skull fractures and their clinical and prognostic aspects were studied in victims with varying severity of brain injury. Of 947 cases, 449 (46%) patients were diagnosed as having basilar skull fracture and 181 (18.6%) had basal spinal fluid leakage.

[Involvement of thyroid hormones in mental recovery following severe craniocerebral trauma].

To study a role of thyroid hormones in the recovery of mental performance, 71 patients (60 males, 11 females) aged 7 to 66 years (mean age 32.7 +/- 3.5) with severe brain injury (TBI).

Thyroid hormones in comatose patients with traumatic brain injury.

The objective was to study if thyroid hormones, cortisol, prolactin and brain injury marker levels were changed in traumatic brain injury (TBI) patients with changing levels of consciousness. We estimated the above named parameters in 32 patients (27 men and 5 women aged 11-55). Admission Glasgow Coma Score was < 8.

[Endogenous intoxication and its treatment with sodium hypochlorite in neurosurgical patients].

Blood plasma levels of medium-mass molecules (MMM), antioxidant activity (AOA), and malonic dialdehyde (MDA) were measured in 51 neurosurgical patients before and directly and 24 h after intravenous drip infusion of sodium hypochlorite (SHC) solution. Preliminary in vitro studies showed the most expressed drop of initially high MDA and MMM levels to be associated with an increase of AOA. It was observed at SHC concentration of 0.

[The clinico-anatomical characteristics and the reasons for diagnostic errors in vascular micromalformations and cavernous defects in the cerebral vessels].

The presurgical clinical diagnosis of vascular micromalformations and cavernous defects of the brain vessels is one of the most intricate problems. Forty-seven observations of patients with verified histological diagnosis of various vascular micromalformations: arteriovenous, venous, cavernous, and undifferentiated ones were analyzed. There was a direct relationship between the clinical course of defects and difficulties in presurgical diagnosis, on the one hand, and the type of vascular micromalformations, the presence of hematomas, residual recurrent hemorrhages, vascular thromboses, the degree of glial hyperplasia and a tumor, on the other.

[The diagnosis of vascular micromalformations in the brain].

Ninety cases with cerebrovascular micro-malformations were analyzed. These abnormalities amount to 5.3% of the total number of patients with arteriovenous malformation.

[The effect of visual deafferentation on changes in the cerebral blood flow during photic stimulation].

With the aid of transcranial dopplerography, linear velocity of the blood flow was recorded in major cerebral vessels in resting and in photostimulation in 18 healthy subjects and 7 patients with unilateral lesion of visual pathway and exclusion of one half of the field of vision. The photostimulation accelerated the blood flow in middle cerebral arteries by 4.3% and in posterior cerebral arteries by 26.
