[Acute disseminated encephalomyelitis and myelitis associated with new coronavirus infection COVID-19. Case report].

Acute disseminated encephalomyelitis (AEM) and acute transverse myelitis (OPM) are autoimmune demyelinating diseases of the central nervous system. Two clinical observations of AEM and OPM developed after suffering acute coronavirus infection (SARS-CoV-2) are presented. Differential diagnosis was carried out with multiple sclerosis, encephalitis of an infectious nature, compressive myelopathy, and opticomyelitis. Both observations show an almost complete recovery of lost functions. The pathogenetic mechanisms of the development of AEM and OPM in patients with coronavirus infection are discussed. The onset of central nervous system dysimmune lesion in the context of coronavirus infection makes it necessary to monitor the clinical situation with the involvement of a neurologist for timely diagnosis and determination of therapeutic tactics that can reduce the degree of disability of patients.

[Molecular markers of endothelial damage in patients with Parkinson's disease].

A comparative analysis of clinical, instrumental and laboratory data in groups of patients with Parkinson's disease and chronic brain ischemia (stages I-II) was carried out. The information obtained in the groups showed significant differences in clinical and instrumental data that indicated the presence of chronic brain ischemia. A significant increase in molecular markers of endothelial damage comparable with the group of chronic cerebral ischemia was identified in patients with Parkinson's disease. The increase in indicators including monocyte chemoattractant protein-1, vascular endothelial growth factor and endothelin-1 is important for the verification of the disease before the appearance of symptoms of chronic cerebral ischemia in the examined groups of patients.

[Rehabilitation potential of disabled persons with consequences of cerebral stroke and effects of factors of the organization of rehabilitation assistance].

The authors demonstrated the possibility for the practical use of the index "Rehabilitation Potential" in the evaluation of the degree of restoration of neurological deficit developed due to cerebral stroke. The most significant factors characterizing the organization and implementation of rehabilitation measures in different periods of stroke and the effect of these factors on the level of rehabilitation potential of disabled persons with consequences of stroke are specified. It has been shown that the perfect organization of restorative treatment has a positive effect on the level of rehabilitation potential of disabled persons.

[Non-medication treatment of headache in children with obesity].

Eighty-eight children with obesity including 30 with exogenous-constitutional obesity (ECO) and 58 with hypothalamic obesity (HO) were studied. Using a clinico-instrumental method, we found that the headache was caused by the dysfunction of autonomous nervous system in children with ECO while disturbances of intracranial hemodynamics, changes of the cerebral functional state and autonomous nervous system as well as hypertension were mostly observed in children with HO. The authors suggest treating headache using bitemporal transcranial magnetic therapy that decreases the intensity and frequency of headache in 89% of children regardless of obesity form and causes of cephalgia.

[Hemostasis and lipid peroxidation in the therapy of brain concussion at exacerbation].

130 patients with brain concussion (BC) and 30 virtually healthy subjects, aged 16 to 50, were examined for the purpose of studying the influence exerted by different drugs affecting blood coagulation, fibrinolysis, lipid peroxidation (LPO) and antioxidant protection at exacerbation. Changes of hemostasis in BC were shown to be of the adaptation nature and to depend essentially on a conducted treatment. Normalized plasma components in the hemostasis system were registered in groups receiving cavinton. The drug, when used, reduced the LPO intensity and intensified the activity of dismutase superoxide on days 9-12 after trauma.

[Neurovisualization methods in diagnostics of consequences in light craniocerebral trauma]. / Metody neirovizualizatsii v diagnostike posledstvii legkoi cherepno-mozgovoi travmy.

The purpose of the case study was to elucidate the frequency rate of pathological changes as registered by computer tomography (CT) and magnetic-resonance tomography (MRT) of the head in patients with chronic cerebral blood-circulation deficiency (CBD), functional disorders and vegetative nervous pathologies in presence (in their medical histories) of closed-type cranial trauma concomitant with concussion of the brain (CB) or without such trauma. A comparative analysis revealed a minor prevalence in the number of pathological changes in patients with CBD concomitant with CB. As for other nosological forms, the quantities of changes, expressed in percent, were virtually identical. A conclusion was made on the need to examine the patients of the discussed category by neurovisualization in the acute and remote periods of trauma.

[Effects of hyperoxia regimes on the state of lipid peroxidation and hemostasis in patients with lesions of the central nervous system]. / Vliianie rezhimov giperoksii na sostoianie perekisnogo okisleniia lipidov i gemostaz u bol'nykh s porazheniiami tsentral'noi nervnoi sistemy.

Lipid peroxidation and some parameters of hemostasis were studied during exposure to various hyperoxia schemes combined with heparin therapy before and after treatment in 124 patients aged 16 to 69 with CNS involvement which developed as a result of atherosclerosis and essential hypertension, 60 of whom presented with initial manifestations of cerebral circulation insufficiency (IMCCI), 33 with posthypoxic encephalopathies (PE), and 31 with ischemic stroke (IS). Hyperoxia mechanisms were differently directed in the studied groups of patients, this necessitating a differentiated approach to the choice of schemes of hyperbaric oxygenation. Use of a short course of hyperbaric oxygenation (up to 3 sessions at 1.2 to 1.25 atA) is recommended for patients with IMCCI and PE. For patients with IS in the acute period hyperbaric oxygenation at 1.4 atA is advisable combined with heparin therapy in doses of 150 to 300 U/kg b.w. a day.

[The effect of different hyperbaric oxygenation regimens on the aggregate status of the blood and on the free-radical oxidation processes in patients with the initial manifestations of cerebral blood supply failure]. / Vliianie razlichnykh rezhimov giperbaricheskoi oksigenatsii na agregatnoe sostoianie krovi i protsessy svobodnoradikal'nogo okisleniia u bol'nykh s nachal'nymi proiavleniiami nedostatochnosti krovosnabzheniia mozga.

Blood rheology, hemocoagulation, free-radical oxidation, acid-alkaline condition of the capillary and venous blood were investigated in 62 ICIB patients before and after treatment which consisted of 8 hyperbaric oxygenation (HBO) sessions or 3 HBO sessions (1.5 atm and 1,2 atm, respectively), the rest patients were not exposed to HBO. The best therapeutic results were achieved with a short-term HBO at a small excessive pressure. The longer HBO regimen provided no positive tendencies in clinical parameters. On the contrary, it provoked blood rheology deterioration, activation of free-radical oxidation stemming from diminished adaptation to hyperoxia in ICIB.
