[Efficiency and safety of using the modified protocol for the administration of the domestic class III antiarrhythmic drug for the relief of paroxysmal atrial fibrillation].

Aim: Evaluation of the efficacy and safety of the modified refralon administration protocol for the relief of paroxysmal atrial fibrillation (AF).

Materials And Methods: The study included 39 patients (19 men, mean age 6312.8 years).

[Detection of Autoantibodies Against the 1-Adrenergic Receptor in the Sera of Patients via the Competitive cell-Based Enzyme Linked Immunosorbent Assay].

Objective: This study aimed to assess the level of anti-1-adrenergic receptor autoantibodies in patients with ventricular arrhythmias with no signs of organic heart disease and with presence of cardiovascular pathology in comparison with a group of healthy volunteers.

Material And Methods: The study included 44 patients with ventricular arrhythmias with no signs of organic heart disease ("idiopathic"), 34 patients with diagnosed dilated cardiomyopathy (DCM) of inflammatory origin, 35 patients with coronary heart disease and ventricular arrhythmias, 12patients with coronary heart disease with no ventricular arrhythmias, and 19 healthy volunteers (control group). The level of autoantibodies against the 1-adrenergic receptor was determined by the developed competitive cell-based enzyme-linked immunosorbent assay (ELISA) and by the standard ELISA using peptides corresponding to the second extracellular loop of the 1-adrenergic receptor.

SMART syndrome: Classic transient symptoms leading to an unusual unfavorable outcome.

Background: Stroke-like migraine attacks after radiation therapy (SMART) syndrome is a rare complication of cerebral radiation therapy that usually presents>10 years after treatment as reversible paroxysmal episodes of neurological dysfunction associated with headaches.

Cases: We report here on two cases of SMART syndrome in long-term survivors of high-grade glioma for whom neuropathological data were available. The course of the disease was unfavorable.

[The conditions for the possible formation of foci of diphyllobothriasis on the lower Don].

There are conditions for forming a diphyllobothriasis focus in the basin of the lower Don. In terms of the population affliction, low risk for its infection and the size of copepods, the focus is differentiated as an Oligocopepoda one of low epidemiological intensity. Its formation is favoured by the activation of the population's migration, favourable ecological and biological conditions for the existence of intermediate and supplementary hosts, the population's habit of having ill-disinfected fish, the pathways of infected material delivery into the reservoirs, the survival periods for broad tape-worm eggs, which are sufficient for diphyllobothriasis pathogens to develop their biological cycle under the conditions of Rostov Province.
