Its etiology remains unknown; interleukin 6 (IL-6) plays an important role in pathogenesis. Castleman disease has two clinical forms: localized (up to 90 % of cases) with a favorable prognosis, treated predominantly by surgical method; generalized (up to 10 % of cases) with less favorable prognosis, treated by pharmacological therapy. The diagnosis is rarely established at the preoperative stage.The aim. To present a clinical case of diagnosis and treatment of Castleman tumor of a rare topical localization.Results. A 66-year-old patient was admitted at the Abdominal Oncology Department of the G.E. Ostroverkhov Kursk Oncology Scientific and Clinical Center.Diagnosis: Retroperitoneal mass on the right found at the preventive examination; no peripheral lymphadenopathy was detected on ultrasound and computed tomography (CT). After the examination, a preliminary diagnosis was made: Gastrointestinal stromal tumor (GIST) of the small intestine mesentery.  Based on the results of the case conference, the decision was taken to perform a surgery – laparoscopic removal of the tumor under endotracheal anesthesia. For surgical approach, a fan-shaped arrangement of ports was chosen. The surgery had no complications. Intraoperative blood loss was 50.0 ml. The total operating time was 98 minutes.According to the results of the histological study, the following diagnosis was made: Castleman disease, unicentric form, hyaline-vascular variant. En bloc surgery is the standard method for the treatment of localized forms of the Castleman disease. In all cases, long-term follow-up shows a long relapse-free period in almost all patients.During follow-up examinations (ultrasound of the abdominal cavity and retroperitoneal space, CT of the abdominal cavity with contrast enhancement, CT of the chest), no disease recurrence was detected during the year of observation.Castleman disease is a rare non-clonal lymphoproliferative disease of unknown etiology. A rare case of its retroperitoneal localization indicates that in cases with an uncertain nature of the peritoneal mass, Castleman disease should be included in the differential diagnostic search.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79373896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acute cerebrovascular disorders are one of the main causes of severe disability in modern society. Russian and foreign researchers register the emerging trend towards rejuvenation of the patients with stroke, which, in turn, significantly increases the relevance of the treatment and rehabilitation of these patients at various stages.The aim. To study the social and hygienic characteristics of the stroke patients and to determine their need for medical rehabilitation in the early recovery period.Materials and methods. We studied the social and hygienic characteristics of 109 patients who had stroke in 2020 and 2021 and underwent rehabilitation in the specialized rehabilitation department of the Southern District Medical Center of the Federal Medical and Biological Agency, and determined their need for medical rehabilitation using the analytical method, the method of expert assessments and questionnaires.Results. The average portrait of a patient with a stroke in the early recovery period is as follows: this is a man aged 61 to 70 years with a higher or secondary specialized education, unemployed, living in the city. Up to 30 % of stroke survivors were recognized as disabled; among which, the persons with more severe disability (groups I and II) predominate – up to 90 %. Implementation of rehabilitation measures in the acute period in the hospital and in the early recovery period in the outpatient clinic is carried out at a fairly low level. The percentage of patients being examined by a multidisciplinary rehabilitation team ranges from 17.4 to 10.1 %.Conclusion. The availability of medical rehabilitation measures in a specialized rehabilitation center is quite limited; more than half of the surveyed contingent (52.3 %) experienced problems in obtaining a referral to treatment, about half of the respondents (46.8 %) waited up to 6 months for a referral, which indicates the need to expand the network of such institutions at the regional level.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83164629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neisseria gonorrhoeae is a facultatively anaerobic microorganism which is extremely demanding to the composition of a nutrient media and cultivation conditions. In a situation of the increasing shortage and cost of foreign components for the preparation of solid nutrient media, it is important to study the possibility of growing hard-to-cultivate microorganisms on domestically produced nutrient media.The aim of the study. To evaluate the growth of gonococcus colonies on two types of solid nutrient media – chocolate agar with growth and selective additives prepared using imported reagents and chocolate agar with growth additives manufactured by “Gem LTD” (Moscow, Russian Federation).Materials and methods. А reference strain of N. gonorrhoeae NCTC 12700/ ATCC 49226 and two types of chocolate agar (the first one – prepared in the State Scientific Center of Dermatovenerology and Cosmetology using imported components and the other one – from the domestic manufacturer “Gem LTD”) were used in the research.Results. The equivalence of the growth properties of both studied types of nutrient media when cultivating pure gonococcus was revealed.Conclusions. Ready-to-use chocolate agar with growth additives produced by “Gem LTD” can be successfully used in the laboratory for the cultivation of N. gonorrhoeae pure culture. Primary isolation of N. gonorrhoeae strains from clinical material is more appropriate to carry out on a medium that suppresses the growth of foreign microflora due to the inclusion of antibiotic additive. The organization of production of domestic bacteriological media for microorganisms with high nutrient requirements reduces the dependence of domestic microbiology on import and ensures their rapid delivery to laboratories.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80816999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These cells are currently assigned a key role in the pathogenesis of many inflammatory diseases, including autoimmune ones: they account for up to half of the lymphocytes present in infiltrates of inflamed tissues. The paper discusses the reasons for the increased plasticity of Th17 cells in comparison with the main T helper populations (Th1 and Th2) and considers in detail the mechanisms of formation of IFNγ producing Th17, taking into account not only the redifferentiation of mature Th17, but also possible alternative pathways, in particular, Th1 cell redifferentiation or naive CD4+T lymphocytes direct differentiation into cells with an intermediate Th1/Th17 phenotype. The main inducers of differentiation of IFNγ producing Th17 cells and the reversibility of this process are also discussed. Particular attention is paid to the methods for identifying Th1 polarized Th17 cells: this population is heterogeneous, and its size significantly depends on the type of markers used to characterize these cells – Th1/Th17-associated transcription factors, key cytokines, as well as chemokine receptors and other membrane molecules. As a result, the data in the works on this problem are poorly comparable with each other. The unification of approaches to identifying a population of Th1 like Th17 cells will solve this problem and make it possible to use an assessment of the size and activity of such a population as diagnostic or prognostic markers.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91204852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The description of a clinical case of sclerochoroidal calcification to improve the efficiency of disease detection through the use of multimodal diagnostics.Material and methods. A 62-year-old patient with complaints of “bright flashes” in her left eye for the past few months, who underwent a standard complex of ophthalmological examinations, supplemented according to indications by optical coherence tomography of peripapillary nerve fibers, macular zone, B-scan, Dopplerography in color Doppler mapping mode. Auxiliary diagnostic methods were magnetic resonance imaging of the orbits and extraocular muscles, computed tomography of the orbits and a biochemical blood test.Results. Considering the anamnesis, the absence of progression of complaints, the data of instrumental diagnostic methods, the absence of pathological blood flow in the area of both eyes formations, the correct diagnosis is most likely to be sclerochoroidal calcification of both eyes, despite the difficulties of the diagnostic process, which consisted in the absence of visualization of foci during ophthalmoscopy.

To study the influence of metabolic disorders that occur against the background of obesity on the state of the airways tone in rats.Materials and methods. Obesity in male Wistar rats was induced using a high-fat and high-carbohydrate diet. In animals, body weight and fat mass were measured, and the heart-lung complex was extracted. In blood serum, the levels of glucose, insulin, leptin, triglycerides, and cholesterol were assessed. Bronchoalveolar lavage fluid was obtained by an open method, in which the concentration of protein, interleukin (IL) 6 and IL-10 was determined. The contractile activity of the isolated bronchial smooth muscle segments was studied using mechanographic method. The effect of acetylcholine (10–7–10–4 M), indomethacin (10–5 M), and forskolin (10–7–10–5 M) on the changes in the tone of airway smooth muscles was assessed.Results. High-fat and high-carbohydrate diet caused an increase in body weight, visceral obesity, hyperglycemia, insulin resistance, leptinemia, dyslipidemia in rats of the experimental group. In the bronchoalveolar lavage fluid of experimental animals, an increase in the content of protein and IL-6 was found, which positively correlated with the level of leptin and the fat mass. In obese rats, the contractile responses of bronchial smooth muscle segments increased in response to the effect of the cholinergic agent acetylcholine. The bronchoconstrictor effect of acetylcholine was reduced by the cyclooxygenase inhibitor indomethacin. In turn, the adenylate cyclase activator forskolin caused relaxation of the airway segments smooth muscles in rats of both groups, which was more pronounced in the experimental group.Conclusion. The obtained results indicate that the change in the reactivity of the respiratory tract can be the cause of  bronchospastic conditions in obesity and of the inflammatory reaction in the respiratory system induced by obesity.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81668807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
