[Unilateral posteroventral pallidotomy in the treatment of drug-induced dyskinesia in Parkinson's disease].

Objective: to determine the efficacy of unilateral posteroventral pallidotomy (PVP) in the treatment of drug-induced dyskinesia (DID) in Parkinson's disease (PD).

Material And Methods: We analyzed surgical treatment of 14 patients with PD complicated by DID who underwent unilateral PVP at the Research Center of Neurology in the period between 2012 and 2015. The clinical type of DID was mainly represented by peak-dose choreoathetoid dyskinesia, more pronounced in the distal limbs, and predominantly unilateral.

Simulation of Viral Hepatitis E in Marmosets.

We developed a model of hepatitis E virus infection in common marmosets (Callithrix jacchus) and determined optimal route of infection, duration, clinical and virological characteristics of infection in laboratory animals. Using this model, we demonstrated that replication of hepatitis E virus primarily occurs in the liver, while virus replication presumed to take place in the intestine was not confirmed in this experiment.

Properties of extracellular DNA from the cerebrospinal fluid and blood plasma during Parkinson's disease.

The cerebrospinal fluid of patients with Parkinson's disease was shown to contain extracellular DNA. Extracellular DNA concentration in the cerebrospinal fluid was 3.3-fold lower than in blood plasma from these patients.

[A combined preparation stalevo in Parkinson's disease: a 5-year experience of continuous dopaminergic stimulation].

Levodopa remains a 'gold standard' for the treatment of patients with Parkinson's disease (PD), but its chronic use is accompanied by fluctuations of symptoms and dyskinesias related to unfavorable pharmacokinetics of levodopa and progressing loss of the nigrostriatal neurons. Prescribing inhibitors of catechol-O-methyl-transferase (enzyme of dopamine metabolism), entacapone or tolcapone, is a perspective approach to the correction of the above-mentioned complications. We followed up 402 patients with PD who received long-term therapy with a combined preparation Stalevo (levodopa/carbidopa/entacapone) for 2-5 years (2.

[Role of hepatitis A and E viruses in the development of autoimmune diseases].

The mechanisms of development of autoimmune diseases may be associated with a complex of genetic, immune, hormonal, and infectious factors. Autoimmune diseases include a wide range of systemic and organ-specific diseases, including autoimmune hepatitis (AIH). It is currently assumed that the pathogenesis of AIH is due to compromised immune regulation in the presence of an exogenous triggering factor.
