[Peculiarities of cerebral structures functioning in adolescents with achondroplasia].

Complex neurophysiological examination (rheoencephalography, electroencephalography) was carried out in 12 adolescents 12 to 18 years old in order to reveal the peculiarities of cerebral structures functioning in adolescents with achondroplasia. Some deviations from the normal values were found out: reduced blood filling of the brain vessels in the pools of a. carotis interna and a. vertebralis, rheoencephalographic signs of intracranial hypertension of mild degree and brain cycling characterized by moderate and significant amplitude increase, presence of pathological types (delta-, theta-) of the rhythmics and the reduction of the physiological ones (alpha-, beta-). At the same time the peculiarities of rheoencephalographic indices were observed while functional testings (hypercapnia, hyperoxia). Brain cycling differed from normal values by weaker response to the weight-bearing, mainly in alpha- and beta-ranges.

[Peripheral hemodynamics in patients with posttraumatic osteomyelitis of leg bones]. / Perifericheskaia gemodinamika u bol'nykh posttravmaticheskim osteomielitom goleni.

Complex examination of peripheral hemodynamics with rheovasography, US-dopplerography and laser flowmetry was carried out in 67 patients with posttraumatic osteomyelitis of leg bones. In these patients before treatment there were sings of functional spasm of popliteal artery, increase of circulatory resistance in the bed of anterior and posterior tibial arteries, decrease of precapillary vessels reactivity by hypertonic type, decrease of capillary elasticity, their spasm, difficulty of blood outflow from great and middle veins. During treatment by transsosseous osteosynthesis main-changed type of blood flow, unstable vascular tones, decrease of greater artery elasticity, hypertoe of pre- and postcapillary small vessels were found. After treatment normalization of vascular tone, balance of status of pre- and postcapillary vessels, normal reaction of capillaries to functional test were demonstrated.

[Reconstruction of vascular bed in the affected segment of the leg in patients with defects of the crural bones complicated by chronic osteomyelitis]. / Vosstanovlenie sosudistogo rusla v porazhennom segmente u bolnykh s defektami kostei goleni, oslozhnennymi khronicheskim osteomielitom.

The article analyses the results of medical rehabilitation of 176 patients with defects in the leg bones complicated by chronic osteomyelitis by methods of transosseous osteosynthesis. In average hospitalization terms of 380.8 +/- 15.6 days, medical rehabilitation was achieved in 88.6% of patients. The results of complex clinical and laboratory examination of 46 patients by means of angiographic, radionuclide, and physiological methods confirm gradual correction of the initial regional arterial insufficiency which was combined with anatomical and physiological rehabilitation of the affected leg by the end of treatment. It was established that the high clinical result of the developed methods of transosseous osteosynthesis is based on the formation of a new zone of the vascular channel in the affected limb segment.
