A clinical case of Loeffler syndrome in an 84-year-old patient with heart, lung, liver, kidney and pancreatic lesions is presented. Difficulties of differential diagnostics of this syndrome because of individual clinical picture and signs of the course are discussed in the article. Timely diagnosis of such a condition will prevent the rapid development of severe complications and carry out appropriate therapy, which will significantly prolong the life of patients with Loeffler syndrome. However, in the presence of nonspecific symptoms, the diagnosis of this disease may be diagnostically difficult for the physician.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139625697","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}

Along with pathogenetic features, they have common characteristics. Immune disorders and oxidative stress are involved in pathogenesis of DLE and SLE. Development of oxidative stress is closely associated with the activation of xanthine oxidoreductase (XOR) enzyme system.Aim of the study was to reveal the features of XOR activities profiles in blood of DLE and systemic lupus erythematosus (SLE) patients.Material and methods. 31 patients with DLE, 56 patients with SLE, 35 apparently healthy individuals were enrolled in study. The activities of two convertible forms of XOR (xanthine dehydrogenase (XDG; EC 1.17.1.4) and xanthine oxidase (XO; EC 1.17.3.2)) were measured in plasma, lysed WBC and lysed RBC. The level of uric acid (UA) was determined in plasma.Results and discussion. In contrast to the control, XO activity was higher and XDG activity was lower in plasma of DLE patients; activities of both XOR forms were decreased in lysed lymphocytes. Activity of XO was lower in plasma, XO and XDG activities were higher in lysed lymphocytes in DLE regardless of the SLE activity. XDG activity in plasma of and XO activity in lysed erythrocytes DLE patients was lower than in low activity SLE, but higher than in the subgroup with moderate and high disease activity. XDG activity of lysed erythrocytes in DLE was higher than in patients with low and moderate SLE activities, but lower than in patients with high diseases activity. Uric acid content in plasma of DLE patients was not differ from the control values, its level was increased at II and III degrees of SLE activity.Conclusions. Changes in XOR activity in plasma and lysed WBC in DLE and SLE are unidirectional, but are more pronounced in the systemic form of the disease. Thus, DLE and SLE are characterized by some common changes in XOR activity, at the same time, XOR blood profiles have distinctive features, which are characteristic for nosology.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139533574","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}

A retrospective analysis of 156 medical records of patients who were on outpatient treatment by an infectious disease specialist at Clinical Medicine Center MedMix was carried out. Patients were divided into three categories according to the age criterion: the first group from 0 to 5 years consisted of 58 (37.2 %) children, the second group was represented by persons from 5 to 18 years old – 58 (37.2 %), the third group was formed by patients from 18 to 53 years old – 40 (25.6 %) people.Results and its discussion. Among children aged 0 to 5 years, boys (67.2 %) more frequently fell sick, and in the group from 18 to 53 years, females (70 %) were more likely to have the disease. Clinical symptoms such as generalized lymphadenopathy (82.7 %), nasopharyngeal lesions (79.3 %) and changes in the general blood test (86.2 %) were most frequently detected in children aged up to 5 years, while fever (81 %) and oropharyngeal lesions (74.1 %) were most frequently detected in patients aged from 5 to 18 years. Liver damage with the development of acute induced viral hepatitis was recorded in all age groups (24.1, 27.6 and 30 %). EBV infection was most frequently diagnosed among children aged from 5 to 18 years and persons aged from 18 to 53 years (in 62.1 and 70 % of cases, respectively, p < 0.05). Mixed infection with the combination of VEB + CMV + HHV-6 was significantly more frequent in children under 5 years of age (34.5 %; p < 0.05).Conclusions. In childhood, the clinical manifestations of infectious mononucleosis were more pronounced. Such intense course of the disease caused frequent visits to an infectious disease specialist and diagnostics with the establishment of an etiological agent. The dominance of EBV infection in the development of infectious mononucleosis in all groups was established. However, at the age up to 5 years, the most common mixed infections were the following combinations: EBV + CMV, EBV + HHV-6, EBV + CMV + HHV-6 and CMV + HHV-6.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139438169","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 student’s physiological and psychological status, as well as the initial motivational setting attitudes are the determining factors. Given this backcloth, the search for ways to improve the health, while aiming at enhancing future qualified specialists’ working and adjustment capacity, appears to be an issue of utmost importance.Material and methods. A longitudinal study involving university students of different years was carried out, through which anthropometric data were evaluated for the same students in their 1st year and then – in their 2nd year of training; the concentration of testosterone and cortisol in saliva, thyroid-stimulating hormone and triiodothyronine in blood serum was measured by ELISA; also, psychophysiological values were estimated through unified questionnaires.Results. The results showed that over the course of education, the students had their hemoglobin concentration, average hemoglobin content in erythrocytes, and leukocyte number decreased. Notable was a significant increase in 3rd year students’ thyroid-stimulating hormone content and a decrease of triiodothyronine and testosterone. A test relying on the Buss – Durkee Hostility Inventory helped to detect an increase in the aggression and suspicion criterion indicators among senior students if matched versus similar values obtained for their freshmen-counterparts.Conclusions. The research outcomes expand the informational and the methodological base required to evaluate an average student’s functional status from the standpoint of a systematic approach and the theory of the norm. Besides, such data will offer an insight into the main mechanisms behind stressinducing, just like stress-limiting, adjustment strategies. This study of the morphofunctional status indicators allows – while within the annual health monitoring approach – identifying the regulatory and the adjustment capacities in students, both at the time they are enrolled as freshmen and further, thus helping predict the potential risk of maladjustment, which, in turn, may serve a useful tool in taking preventive measures, the final goal being to maintain students’ health through their higher education training period.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139534427","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 study sample included 20 young euthyroid males aged 25–44 years, permanently residing in Arkhangelsk. To study the influence of the photoperiodic factor on the functioning of the endocrine system, four months were selected, which are distinguished by the clearest contrast of daylight hours: March (increased daylight hours), June (maximum daylight hours), September (reduced daylight hours) and December (minimum daylight hours). The concentration of dopamine was determined in the blood plasma, and the indicators of the thyroid profile and cortisol level were studied in the serum.Results. Analysis of the data obtained revealed two types of reactions from the dopaminergic system and cortisol content during the period of minimal daylight hours. Along with the seasonal dynamics of dopamine, there is a change in the activity of the pituitary-thyroid system.Conclusions. In males, whose dopamine levels increase from September to December, the concentrations of cortisol and thyroid hormones also increase, that is, several stress systems are simultaneously activated – the adrenal medulla and cortex, the thyroid gland. Thus, there is a more pronounced reaction to the appearance of seasonal stress factors, which may be due to the rather successful adaptation of the respondents to the environment and may indicate that respondents with dopamine levels decreasing or not changing from September to December either have reduced reserve capacity of the body, or hormones are more actively spent on metabolic processes.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139534790","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}
