[The effect of non-invasive brain stimulation on neuroplasticity in the early recovery period after ischemic stroke]. / Vliyanie neinvazivnoi stimulyatsii golovnogo mozga na neiroplastichnost' v rannem vosstanovitel'nom periode ishemicheskogo insul'ta.

The post-stroke cognitive impairment syndrome (PSCI) develops in 10-80% cases of ischemic stroke and leads to a significant patients' quality of life impairment. The standard program of cognitive rehabilitation includes nootropic agents therapy and neuro-cognitive training. The additional various methods of non-invasive brain stimulation (NIBS) application can improve the results of PSCI rehabilitation. PURPOSE OF THE STUDY: Studying the different variants of NIBS influence on synaptic neuroplasticity in the early recovery period after ischemic stroke. MATERIAL AND METHODS: The rehabilitation of 62 patients with PSCI syndrome after ischemic stroke outcomes were studied. The patients were assigned to 5 groups. Patients from the control group underwent standardized nootropic therapy and course sessions with a neuropsychologist. The rest of the patients were divided into 4 groups, in which, in addition to the basic program of cognitive rehabilitation, different options for the course use of NIBS were used: photochromotherapy (PCT) with narrow-band optical radiation (NOR) with a wavelength of 530 nm (green light); rhythmic transcranial magnetic stimulation (rTMS) with a low-intensity high-frequency running pulsed magnetic field; infrared radiation with a wavelength of 1-56 microns, modulated by terahertz frequencies (IRMT); bioacoustic correction (BAC). We analyzed the dynamics of changes in scores of MMSE scales, FAB, Roshchina. In order to assess the effect of NIBS on neuroplasticity, the concentrations of BDNF and antibodies to the NR2 fragment of the NMDA receptor were evaluated before and after the completion of the rehabilitation course. RESULTS: Concentration values of antibodies to the NR2 subunit of the NMDA receptor in all groups remained consistently above the norm (more than 2 ng/ml) throughout the entire course of rehabilitation. Differences between groups in the dynamics of BDNF concentration in the peripheral blood were revealed. There was a significant (p<0.05) decrease in its concentration by almost 2 times by the end of rehabilitation course in control group. In the rTMS and IRMT groups, a decrease in the BDNF concentration was also recorded in dynamics, which, however, did not reach a significant level. There was no decrease in BDNF levels in the BAC group. There was an increase of this level in the PCT group. CONCLUSION: The use of different types of NIBS in the program of cognitive rehabilitation of patients with PSCI syndrome contributes to an increase in the rehabilitation potential due to the activation of neurotrophin-mediated synaptic neuroplasticity. Green light PCT and BAC have the greatest effect on increasing neuroplasticity after ischemic stroke.

[Structural epilepsy or herpes simplex encephalitis relapse: diagnostic problems]. / Strukturnaya epilepsiya ili retsidiv gerpeticheskogo entsefalita: diagnosticheskie trudnosti.

The article gives the clinical case of herpes simplex encephalitis relapse with the resistant seizures in a child. What we describe is a clinical approach towards the differential diagnostic of the seizures in structural epilepsy, which are resistant to anticonvulsants, or late herpes simplex encephalitis relapse. Good clinical perspective may be the indication of the intratecal synthesis of the IgG-specific antibodies to the herpes simplex type 1 and 2. Conducting etiotropic treatment with the appointment of acyclovir and pathogenetic therapy with the use of Cytoflavin contributed to the rapid and stable remission of epileptic seizures and regression of neurological deficit.

Acrodystrophic axonal polyneuropathy with celiac disease: a case report.

BACKGROUND: Patients with celiac disease present with not only gastrointestinal symptoms but also extraintestinal manifestations such as anemia, osteopathy, dermatitis herpetiformis, and celiac neuropathy. Despite a fairly wide range of celiac neuropathies, we report a case of the acrodystrophic variant of celiac polyneuropathy, which has not been previously described. CASE PRESENTATION: A 41-year-old Ukrainian male suffered from symmetric, sensorimotor axonal polyneuropathy and encephalopathy associated with celiac disease, which is characterized by severe trophic disorders in the lower extremities (trophic ulcers, hyperkeratosis, and anhidrosis). Acrodystrophic changes in the lower extremities were due to both neurogenic and direct immunoinflammatory damaging effects. Clinical-electrophysiological dissociation was also noted, which was represented by a gross axonal lesion with the preservation of muscle strength. The absence of enteropathic manifestations was accompanied by the pronounced histological changes in the duodenal mucosa by IIIb stage of Marsh. A gluten-free diet in combination with membrane plasma exchange and intravenous pulse methylprednisolone was prescribed to reduce the severity of sensory disorders and regression of encephalopathy within 7 months. CONCLUSION: Celiac disease may be a potential cause of neuropathy and encephalopathy in adult patients. Further immunosuppressive treatment protocols for both intestinal and extraintestinal manifestations of celiac disease are required.

[Acute disseminated encephalomyelitis]. / Ostryi rasseyannyi entsefalomielit.

Acute disseminated encephalomyelitis (AEM) is an immune-mediated inflammatory demyelinating disease of the central nervous system (CNS), usually single-phase. In WREM, multiple lesions of the central nervous system of an inflammatory-demyelinating nature accompanied by extremely polymorphic neurological disorders develop acutely or subacutely. The review considers the issues of epidemiology, trigger factors of the inflammatory process, clinical manifestations, differential and molecular diagnostics of WECM, and outlines the ways for further study of this pathology.
