[Clinical picture, diagnostics and prophylaxis of a syndrome in conditions of the Far North].

The analysis of a clinical picture barometeosensitivity in a seaside zone of the Far North is carried out in the article. A diagnostic test included the following laboratory assessments: complete blood count, complete urinary analysis, biomedical measurement assessment, immunology blood research and functional renal test; analysis of the level of an electrolyte in the blood and hormone receptor status; and the following instrumental diagnostics: The auscultatory Korotkov's method of determining blood pressure, electrocardiography, variational pulsometry, chest X-ray, mechanocardiography, echocardiography and abdominal ultrasound; and also consultation of ophthalmologist and neuropathologist. Every patient should keep a diary "weather - health" before and after the treatment. Peculiarities of cardiovascular system, vegetative systems and neuroendocrine system of servicemen, coming to the Far North and mechanisms of development of barometeosensivity were revealed. It has been established that atmospheric pressure variation affects systolic and diastolic blood pressure, heart rate, systolic discharge, Kerdo index, effectiveness of myocardial function, end-diastolic and end-systolic volume, level of cholesterol, triglycerides, kalium, adrenalin, triiodothyronine, blood plasma and plasma renin activity in barometeosensetiv servicemen. The criteria of diagnostics of barometeosensivity in conditions of the Far North are suggested. The influence of baromemteosensivity on the combat capability of serviceman is researched.

[Surgical management of patients with pathological deformities of carotid arteries].

Surgical management of pathological deformities of the internal carotid arteries, a cause of chronic brain ischemia, is discussed. This pathology is very common and is found in 25% of all individuals who underwent preventive medical examination according to the ultrasonography data. Most deformities do not pose any threat to patients, while some of them may cause ischemic stroke and chronic brain ischemia. The study included 165 patients with the known follow-up history who had been operated on at the N.N. Burdenko Neurosurgical Institute since 2001. A total of 196 reconstructive interventions of carotid arteries were analyzed. The indications for surgical management of pathological deformities based on clinical symptoms and identification of the signs of vascular wall dysplasia are thoroughly discussed. The local and cerebral hemodynamics during pre- and postoperative period are analyzed. The results of pathomorphological examination of the resected fragments of the deformed arteries are presented; they show that the changes are identical to those in patients with fibromuscular dysplasia. The follow-up history of the patients was recorded; it showed a sustained regression of transitory ischemic strokes and cerebral symptoms in most cases (69%). For proper indications for surgical management, reconstructive surgical interventions are a reliable and effective method for treating chronic brain ischemia and preventing recurrent ischemic strokes in patients with deformities of carotid arteries.

[Oxygen and hemodynamic support for physical load in neurocirculatory dystonia]. / Kislorodnoe i gemodinamicheskoe obespechenie fizicheskoi nagruzki pri neirotsirkuliatornoi distonii.

Spiroergometric examinations were carried out in 148 students with neurocirculatory dystonia. The adaptation reaction of the cardiorespiratory system to different load strength was studied. The authors used a complex approach with evaluation of the functional parameters of the heart, indices of central hemodynamics and analysis of respiratory gases. As a result of the investigation signs of deadaptation to physical load in neurocirculatory dystonia were revealed.
