To assess the dynamics of coagulation parameters and the influence of its initial values on the development of postoperative thrombohemorrhagic complications in male and female patients undergoing large joint arthroplasty and received combination hemostatic and anticoagulant therapy. Methods. A retrospective analysis of the medical records (n=253) of patients with arthroplasty, were divided into two groups based on the time differences between prescription of hemostatic and anticoagulation therapy. The first group includes 145 patients (57.31%, 112 women and 33 men) with time differences ≤17 h, and the second group includes 108 patients (42.68%, 78 women and 30 men) with time differences 18–24 h. The dynamics of coagulation test results were analyzed, and the influence of its initial value on the risk of postoperative thrombosis or bleeding was assessed. Results. Thrombohemorrhagic complications were recorded in 27 (10.67%) patients, of which 22 (81.48%) were observed in group 1. In the first group, thrombosis developed in regimens with tranexamic acid (p=0.038) with 2.2 times higher incidence than in group 2 (p=0.023). The risk of thrombosis of women in the group 1 was increased by an initially low level of international normalized ratio [relative risk (RR) 13.333, p=0.00032] and activated partial thromboplastin time (RR=5.8, p=0.037). The risk of bleeding in group 1 increased by an increasing preoperative ­level of activated partial thromboplastin time (RR=18, p=0.0012 and RR=28, p=0.00022, respectively) for all patients and by a decreasing fibrinogen level (RR=23.25, p=0.00065) and platelets count (RR=10.2, p=0.038) for women. Conclusion. To minimize the risks of thrombosis and bleeding after arthroplasty, especially in patients with initial deviations of hemostasis parameters from the norm, and, in particular, when using tranexamic acid as a hemosta­tic agent, it is recommended to observe the time interval between hemostatic and anticoagulant pharmacothe­rapy for at least 18 hours.","PeriodicalId":17798,"journal":{"name":"Kazanskiy meditsinskiy zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89667515","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}

To determine the level of lipopolysaccharide-binding protein (LBP) in acute intestinal infection, depending on the etiology and severity of the disease, and the effect of interleukin (IL)-1β and IL-10 levels on the expression of LBP. Methods. Serum samples of 62 patients were assayed by solid phase enzyme-linked immunosorbent assay using a set of reagents ELISA (USA) and Vector-best (Novosibirsk) for levels of LBР, IL-1β, IL-10. The first group inclu­ded 33 patients with bacterial intestinal infection, the second group consisted of 29 patients with viral diarrhea, and the control group comprised 20 conditionally healthy patients. Analyses were performed using Microsoft Excel 2010 and Statistica version 6.0 software. Statistical differences were determined by using the Mann–Whitney U Test, the p-value ≤0.05 were regarded as statistically significant. Spearman’s correlation coefficient was used to examine relationships. Shapiro–Wilk W test was used to check for normal distribution of the features. Results. We detected the presence of LBP in all the studied groups, with the content of LBP was significantly increased in the group of bacterial intestinal infections compared with other groups. With regard to disease severity, LBP level was the highest for mild acute intestinal infections caused by bacteria, and for viral diarrhea, fluctuations in LBP did not exceed the norm. In intestinal infections caused by bacteria, the levels of LBP were directly related to the levels of IL-1β and IL-10. Conclusion. Detection of LBP concentration can be used for the initial differential diagnosis of intestinal infections caused by bacteria, which would significantly narrow the diagnostic search and determine the tactics of etiotropic therapy; also, considering the relationship between the concentration of LBP and disease severity, this indicator can be used as a predictive sign of the course of the disease.","PeriodicalId":17798,"journal":{"name":"Kazanskiy meditsinskiy zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83673934","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}

To improve the results of surgical treatment in patients with large lipomas by using the device for closing the edges of wounds, allowing local preventive hemostasis in the surgical wound area, to create optimal conditions for atraumatic suturing and thereby reduce the amount of intraoperative bleeding and subsequently reduce the amount of postoperative wound complications. Methods. The results of treatment of 105 patients with different localization of large lipomas were analyzed. Lipomas ranged from 8.0 to 20 cm in diameter. All patients were divided into 2 groups: the control group consisted of 53 (50.5%) patients for which used the traditional technique of tumor excision with closing surgical wounds, and the study group with 52 (49.5%) patients, for which to reduce tissue damage during tumor removal and the edges of wound suturing, one of the device variants developed by us was used, approximation-distraction device. Fisher's exact test was used for the comparison of the outcomes rate, a p-value <0.05 was considered statistically significant. Results. Surgical wound complications occurred in 7 (6.7%) of 105 patients. In the study group, surgical wound complications occurred in 1.9% (1 observation), in the control group 11.3% (6 observations). Surgical wound complications were severity grade I and grade IIIa. Complications of the first grade did not require a debridement and will regress on its own; in grade IIIa complications, an opening, excision and drainage surgical wounds were performed without general anesthesia. Conclusion. Moderate local selective near-tumor tissue compression that occurs when the device branches come closer to each other accelerates spontaneous thrombus formation in damaged small vessels. This creates favorable conditions for the surgeon to work in a “dry” wound.","PeriodicalId":17798,"journal":{"name":"Kazanskiy meditsinskiy zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90683730","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}

To assess the degree of fungal contamination and the species composition of the fungal microbiota of residential apartments in Kazan Methods. A mycological study of 90 air samples and 60 samples from sites of fungal biodeterioration from the re­sidential buildings of Kazan was carried out using cultural and microscopic methods. Results. The presence of micromycetes fungi were detected in 90% of air samples and 100% of samples from sites of biodeterioration. Higher fungal species diversity was noted in the sites, compared with air samples. Fungal concentrations in indoor air varied between 8 and 360 CFU/m 3 . Fungal community composition analysis of the sites of biodeterioration showed that the surfaces were more frequently contaminated by undemanding and capable of growth at different moisture levels fungal species (Penicillium spp., Aspergillus spp., Rhizopus stolonifer). The resulting fungal plaque can create conditions favorable for aggressive fungal species that actively damage materials (Chaetomium spp., Acremonium spp., Aureubasidium spp). Allergenic fungi, as well as potentially pathogenic and toxin-forming species, were widespread in the air that can be a health risk factor. A quantitative assessment of air mycobiota indicated the moderate level of fungal contamination. Conclusion. The presence of potentially pathogenic, allergenic and biodegradable fungal species in the sites of biodeterioration has been confirmed, as well as the relationship between airborne fungal contamination and the spread of fungi in indoors, confirming the need to prevent fungal biodeterioration and control indoor air quality.","PeriodicalId":17798,"journal":{"name":"Kazanskiy meditsinskiy zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85140124","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 review considered the prevalence of pathology, the most common causes of dystrophinopathy, and the role of dystrophin not only in the functioning of muscles but also in the architectural organization of the Central nervous system. The disease classification based on stages and forms, initial clinical manifestations of the early and late stages of the disease, as well as neuropsychological, orthopedic, respiratory and cardiovascular disorders, are described in detail. The relevant to date diagnostic algorithm for suspected DMD, biochemical blood analysis, genetic, morphological (immunocytochemical staining of muscles with dystrophin antibodies) and instrumental (ultrasound, MRI) methods of examination are presented in detail. Particular attention in the diagnosis of DMD and objectification of disorders is given to assessment tests [Bailey’s and Griffiths scales, Albert's Test of Infant Posture and Motor Assessment Scale, Expanded Hammersmith Functional Motor Scale (HFMSE), the Gross Motor Function Measure (GMFM), and the 6-minute walk test (6MWT)]. The review presents the advantages and disadvantages of modern invasive and non-invasive diagnostic techniques of the disease, indicating their reliability and the possibility of application at early stages, including prenatal. In conclusion, the treatment of DMD and its most frequent complications, both widely used in practice and at the stage of clinical research, is highlighted. It was emphasized the importance of rehabilitation measures that improve the duration and quality of life of patients with DMD.

To assess the impact of the number of children in the family on breastfeeding duration and vaccination coverage. Methods. 1724 mothers of 1-year old children were randomly chosen from seven children's polyclinics in St. Petersburg for an anonymous survey that was conducted by a specially designed form “Questionnaire of a mother of 1-year old children”. The questionnaire comprised of 20 open-ended and closed-ended questions, and included questions about: (1) timing of the attachment to the breast in obstetric hospitals; (2) causes and timing of breastfeeding abandonment; (3) presence or absence of vaccinations in the first year of life according to the National preventive vaccination schedule; (4) and reasons for mothers refusing to vaccinate their children. Results. The proportion of mothers who started artificial feeding in maternity wards immediately after the birth of the baby was the smallest among women for whom this baby was the first-born (3.4%), and the largest among fami­lies with many children (11.3%). On average, mothers with one child are breastfed until 7.36±0.11 months, with two children until 8.29±0.11 months, with three or more children until 8.78±0.10 months. By using one-way analysis of variance (ANOVA), it was shown the effect of the number of children in the family on the duration of breastfee­ding (F=3.3). Correlation analysis revealed the negative relationship of the number of children in the family with the proportion of women who continued breastfeeding until 3 and 6 months (r xy =–0.82 and r xy =–0.88, respectively), and positive relationship with the proportion of mothers who continued to breastfeeding the baby after reaching a year (r xy =0.89). 12.3% of children of one-child families were not vaccinated according to the National preventive vaccination schedule, 17.7% with two-child families, 28.1% in families with three or more children. It was revealed the significant cross-group effect of the number of children in the family to vaccination coverage (F=48.7).

Zimnitsky to another prominent Russian scientist, the beacon of Russian physiological science — A.F. Samoilov. This question concerned the origin of the giant positive T wave in the first QRS complex after the ventricular extrasystole on the electrocardiogram. The question remained unanswered. We believe that this was because by the end of the 20s of the XX century (S.S. Zimnitsky died in 1927), the delicate mechanisms of repolarization processes were not able to understand, in both healthy and diseased myocardium. The article sets forth our original point of view on the genesis of such a T wave in S.S. Zimnitsky. We believe that a scientific discussion on this issue is quite possible.
