[The role of atherosclerotic coronary arteries lesions in development of new-onset atrial fibrillation after coronary artery bypass surgery].

Aim    To study the relationship between the type of circulation, severity and localization of atherosclerotic damage of coronary arteries, results of laboratory and instrumental tests, and historical data in patients with multivascular coronary lesions and atrial fibrillation (AF) that developed after coronary bypass surgery.Material and methods    This was a novel, retrospective study of data of patients after elective coronary bypass surgery at the Cardiac Surgery Department #1 of the N.V.

The article reveals the formation and work of the Department of Urology during the Grear Patriotic War (1941-1945) based on the memories of its first head, professor A.I. Vasiliev.

[Opportunistic microorganisms: the causative agents of food toxicoinfections and acute intestinal diseases].

The analysis of sporadic morbidity due to acute intestinal infections and toxicoinfections caused by potentially pathogenic microorganisms is presented. The hypothesis stating that different pathogenic agents have different levels of pathogenic potential at a given stage of their evolution is proposed. Microorganisms with a low level of pathogenicity potential are characterized by the prevalence of the syndrome of toxicoinfection and by the rarity or absence of the syndrome of an acute intestinal disease.

[Role of several conditionally-pathogenic enterobacteria in group acute intestinal diseases and food poisonings of unestablished etiology].

Results of studying group acute intestinal diseases of obscure (from the point of view of isolation of commonly known pathogenic bacteria of enteric family) etiology coursing by the type of food poisoning, in which conditioned pathogenic enterobacteria (Enterobacter cloacae, Klebsiella) demonstrated that the occurrence of these diseases was connected with ingestion of the same food product infected with the mentioned bacteria due to disturbance of the sanitary-epidemic regimen and rules of food storage. Carrier stage of conditioned pathogenic bacteria identical to those isolated from the patients was noted in contacts by the factor of infection transmission. Accumulation of factual material is necessary to solve the role played by conditioned pathogenic enterobacteria in such diseases.
