[Hormonal markers of cognitive impairment in patients with the first stroke].

The relationship between the content of serum hormones (thyrotrophic hormone, thyroxin, dehydroepiandrosterone (DHEA), DHEA sulfate, prolactin) and cognitive impairment at the acute phase of ischemic stroke in the 1(st), 7(th) and 21(st) day was investigated. There was the correlation between the hormone concentrations and severity of cognitive impairment. This finding supports the role of the hormones in cognitive functioning and their impairment in the acute phase of stroke.

The effects of hormones of the hypothalamo-hypophyseal-adrenal, renin-angiotensin, and thyroid hormone systems on the formation of dyscirculatory encephalopathy.

Measurements were made of plasma levels of free (f) thyroxine (fT4), triiodothyronine (fT3), thyrotropic hormone (TSH), adrenocorticotrophic hormone (ACTH), aldosterone, and renin in patients with dyscirculatory encephalopathy (DE). Their influences on the development of chronic circulatory insufficiency were assessed. A total of 39 patients were studied (aged 45-73 years) with DE stages I and II, without acute or chronic (in the exacerbation phase) somatic illness.

[The influence of the hormones of hypothalamo-pituitary-adrenal, renin-angiotensin, and thyroid hormonal systems on formation of vascular encephalopathy].

The aim of the study was to investigate the concentration changes of free (f) thyroxine (fT4), triiodothyronine (fT3), thyrotrophic hormone (TTH), adrenocorticotrophic hormone (ACTH), aldosterone and renin in the blood plasma of patients with vascular encephalopathy (VE) and to evaluate their influence on formation of chronic blood circulation deficiency. Thirty-nine patients with VE of stages I and II, aged 45-73 years, without current acute or chronic (in exacerbation stage) other somatic diseases have been studied. The results revealed that a different extent of diffuse lesion of brain tissue was accompanied by an own pattern of thyroid homeostasis: 1) significantly higher TTH levels with intact regulatory negative feedback "fT3-TTH" in patients with VE, stage 1; 2) significant TTH concentration decrease, with pronounced suppression of thyroxine conversion to triiodothyronine and interaction disturbance in the "fT3--pituitary gland" system, in patients with VE in stage II.

[The influence of hormones of stress-promoting system on the course of acute ischemic stroke].

Experimental and clinical studies have proved an important role of the reaction of a stress-realizing endocrine system for both a course and an outcome of acute somatic diseases. That is why plasma concentrations of thyroxine (T4), triiodo-thyronine (T3), thyrotropic (TTH) and adrenocorticotropic (ACTH) hormones as well as of renin were measured during the 1-st week of acute ischemic stroke (AIS) in relevant patients for determination of their prognostic significance. 16 patients with hemispheric AIS were examined.

[Effectiveness of computerized tomography of the temporal bone in the diagnosis of chronic suppurative otitis media].

Temporal bone computed tomography findings were compared to those obtained at operation in 30 patients with chronic OMP. The comparison demonstrated high informative value of CT examinations which provide exhaustive characteristics of the pathological process important for preparation to and performance of relevant surgery.
