Background. The dental health is an integral part of a person's well-being. Students of higher educational institutions comprise a health risk group, since they experience extensive physiological changes and personal socialization. The impact of connective tissue dysplasia on dental health is a relevant research task.Objective. To analyze the correlation between dental pathology and phenotypic signs of connective tissue dysplasia in first-year students.Methods. A cross-sectional clinical study of the dental health and phenotypic signs of connective tissue dysplasia was conducted as part of routine dental examination of 263 first-year students of KubSMU, aged 18–23. All participants were divided into 2 groups: group 1 – participants with 0-2 signs of connective tissue dysplasia (n = 108); group 2 – participants with 3 or more signs of dysplasia (n = 155). Statistical analysis of the results was carried out using Microsoft Excel 2010 and Statistica 6.0.Results. Unsatisfactory and poor oral hygiene levels in the group of participants with connective tissue dysplasia outnumber these levels in the control group by 30% and 22%, with very poor level in the second group 2.3 times higher (p ≤ 0.05). The incidence of noncarious tooth pathology in individuals with dysplasia is 26% higher than in the control group. The caries intensity index in group 2 is almost 20% bigger than in the control group. As expected, the group of participants with no signs of dysplasia revealed better periodontal health, namely 51.85% versus 45.81% (p ≤ 0.05). In terms of mucosal pathology, a statistical significant difference between groups 1 and 2 was noted for traumatic injuries (16.35% and 19.35%, respectively). Dentofacial abnormalities were observed more often in individuals with 3 or more phenotypic signs of connective tissue dysplasia.Conclusion. Higher morbidity rate of caries and noncarious pathology in the group of first-year students with 3 or more phenotypic signs of connective tissue dysplasia, compared to the group with 0–2 phenotypic manifestations of dysplasia, indicated the need to create a database of the dentofacial profiles of students, develop an algorithm for regular medical check-up of students, as well as provide differentiated preventive and therapeutic measures for students with dysplasia.

Background. Prostate cancer is a frequently diagnosed malignant disease in men. At present transrectal ultrasound is the most common technique for imaging the gland. Traditionally, a combination of grayscale and Doppler modes is used. In order to make transrectal ultrasound of the prostate more informative, the contrast-enhanced techniques are recommended to apply. Contrast-enhanced ultrasound can provide quantitative assessment, which, in turn, increases the objectivity of the results obtained.Objective. To evaluate potential of contrast-enhanced transrectal ultrasound for differential diagnosis of focal pathology of the prostate.Methods. A single-center retrospective comparative study of contrast-enhanced transrectal ultrasound of the prostate gland in 66 patients was carried out at the Republican Clinical Oncological Dispansery, the Republic of Tatarstan. The inclusion criteria was the presence of focal pathology in the peripheral zone of the prostate gland. The median age of patients was 67. The following quantitative perfusion parameters were analyzed: time to peak, peak intensity, descending time, area under the curve and an additional index calculated for each of the specified parameters. The resulting enhancement curves were also analyzed by measuring enhancement angles (β) and washout angles (α). SPSS 13.0 (IBM SPSS Statistics, USA) was used for data analysis.Results. The combination of “angle ß ≥69.5°+ angle α≤69.5°” with sensitivity of 92.7%, specificity 80.0% proved to be the most informative. The sensitivity and specificity of the obtained threshold values “enhancement angle ß≥69.5°” comprised 73.2% and 60.0%, respectively, “washout angle α≤69.5°” — 63.4% and 56.0%, respectively. According to the analysis of perfusion quantitative parameters the test “peak intensity ≥ 34.1 dB” with sensitivity of 75.6%, specificity of 84.0% has the most informative value in the diagnosis of prostate cancer.Conclusion. Quantitative analysis of contrast-enhanced transrectal ultrasound of the prostate gland provides objectification of the study, and the use of threshold values increases the informativity in the differential diagnosis of focal lesions of the prostate gland.

Background. Parkinson's disease is a neurodegenerative disorder that leads to severe disability, especially in its advanced stages. Medical care should be performed in accordance with modern clinical recommendations and standards. Assessment of the quality of medical care in the Russian Federation is carried out via examination of medical documentation by insurance experts regarding compliance with Russian standards and other regulatory documents.Objective. To study the predictors for unfavorable course of Parkinson's disease based on routine examinations of the quality of medical care.Methods. The cohort retrospective study included 7,264 examinations of the medical care quality of 1,754 patients with Parkinson's disease for the period from 2011 to 2018 in the Russian Federation. The study focused on two indicators: presence/absence of disease progression and determination/aggravation of a degree of disability or maintenance of the previous social and professional activity. The obtained data were used to develop diagnostic tables with prognostic factors of Parkinson's disease according to A. Wald. Statistical analysis of the results was carried out using Statistica 13 (StatSoft, USA). Results. Diagnostic tables have been developed to determine the prognostic factors affecting the progression of Parkinson's disease and, accordingly, decreasing the degree of social and/ or professional activity and to assess the diagnostic factors when the risk of the disease aggravation will be more than 95%.Conclusion. The greatest progression of Parkinson's disease (p < 0.05) was observed in the cases of poor collection of complaints, history and clinical evaluation of the patient's condition, inadequate prescription or absence of prescription of levodopa when indicated, as well as defects in the correction of additional disorders. The likelihood of social disadaptation in patients with Parkinson's disease (p < 0.05) was found to be greater in the cases of poor collection of complaints and history, neurological examination and clinical evaluation of the patient's condition as well as inadequate prescription or absence of prescription of levodopa when indicated.

Background. An analysis of published results on the chemical structure, pharmacodynamics and pharmacokinetics of hepatoprotective agents, as well as their practical application, shows that a holistic view on the pharmacology of hepatoprotective agents is yet to be developed. Thus, the relationship between antioxidant activity and the effectiveness of reducing hepatocyte cytolysis remains unclear. Another difficult question concerns indications for the application of hepatoprotectors, selection of a particular drug and treatment duration.Objectives. To investigate the effects of hepatoprotective agents with different mechanisms of action on the indicators of oxidative metabolism in the blood of patients with alcoholic hepatitis.Methods. Four groups of patients were involved in the study. The 1st group consisted of relatively healthy male patients (n = 15). The remaining groups (10 individuals in each) were represented by patients with moderate alcoholic hepatitis. Patients of the 2nd group received remaxol; patients of the 3rd group received ademetionine; patients of the 4th group received ursodeoxycholic acid. Prior to and following treatment, the indicators of cytolysis and oxidative stress in blood were determined. Statistical data processing was carried out using the StatPlus v 7 (AnalystSoft Inc.) software package.Results. According to the observed changes in the cytolytic syndrome marker enzymes, all three hepatoprotectors under study expressed comparable efficacy. After treatment according to any of the applied schemes, the ALT and AST activity in the blood plasma decreased by 56–68% and 75–81%, respectively, compared to their initial values. In comparison with the control group, the total antioxidant activity of the blood plasma decreased by 20–27%; the content of TBA-reactive products in the erythrocyte suspension increased by 61–87%. The remaxol, ademethionine or ursodeoxycholic acid therapy led to a partial normalization of the abovementioned parameters without significant differences between the experimental groups. The concentration of reduced glutathione in the erythrocyte suspension and the content of thiol groups in the blood plasma of patients were reduced in comparison with the control group by 16% and 26%, respectively. After therapy, these indicators also increased by 12–15%, although no predominant effect of either of the studied hepatoprotectors was revealed.Conclusion. The conducted comparative study indicated the absence of a specific antioxidant effect among the pharmacological mechanisms of action of remaxol, ademethionine and ursodeoxycholic acid. In this regard, further research should be carried out to investigate the effect of hepatoprotective drugs on pathobiochemical changes and to analyse a relationship between the antioxidant effect and the efficacy of reducing the level of hepatocyte cytolysis.

Published: February 2023

The parent-teacher interaction has been identified as a critical component in the development of children. Teachers' capacity to educate children is influenced by the level of trust parents have in them. Creating a supportive environment at home and cooperating with the school are essential components of a positive educational experience for all parties involved. Prior research, however, found little parental involvement particularly in establishing a quality relationship with the schools in Indonesian kindergartens. This research aimed to examine Indonesian parents’ degrees of trust and communication toward the teachers in 8 kindergartens in Dairi regency, North Sumatra. In constructing the questionnaire, 9 early childhood education practitioners were invited to make content suggestions before conducting a validity test and reliability through factor analysis. The validity is guaranteed by the Kaiser-Meyer-Olkin Measure result of .872 and Barlett's Test (Chi-Square = 3451.561, df = 406, p 0.05). The reliability was measured using Cronbach's Alpha obtaining an alpha coefficient of .870, indicating good reliability. The findings from the 203 questionnaires consisting of 29 items that were distributed indicate parents’ favorable attitudes toward teachers. Besides, the parent’s background does not reflect their attitudes and practices. Suggestions, including delivering the concept of partnership to the parents and increasing the opportunities of participating in school activities, are provided to promote greater quality of the parent-teacher relationship.

Objectifs : La traumatologie routière représente 13,1 décès pour 105 habitants en Guadeloupe. Marie-Galante (MG), île de l’archipel guadeloupéen, située dans les Antilles françaises, est fortement impactée par l’accidentologie routière. La prise en charge de ces victimes implique des spécificités organisationnelles liées à la géographie et au système de soins. Les objectifs de ce travail sont la description épidémiologique des victimes d’accident de la voie publique (AVP) et l’évaluation de la prise en charge (PEC) médicale initiale des victimes les plus graves.
Méthodes : Étude observationnelle rétrospective de 2016 à 2018 incluant les victimes prises en charge par le service médical d’urgence et de réanimation (Smur) et/ou par le centre hospitalier de Sainte-Marie (CHSM) à Marie-Galante. Les patients ont été répartis par critère de gravité : instables, critiques, potentiellement graves ou stables.
Résultats : Sur la période, 499 victimes ont nécessité une PEC : 164 (33 %) impliquant des véhicules légers, 217 (43 %) des deux-roues motorisés et 60 (12 %) des vélos. La population est jeune (29 [21–49] ans), et masculine (sex-ratio H/F : 3,3). Le CHSM a pris en charge 467 (95 %) victimes, 6 (1 %) étaient instables, 11 (2 %) critiques, 142 (28 %) potentiellement graves et 264 (53 %) stables ; 7 (1 %) ont bénéficié d’un transfert héliporté (TH) direct vers le centre hospitalier universitaire de Guadeloupe (CHUG), 52 (10 %) d’un TH secondaire après une PEC au CHSM. Tous les patients instables et 10 (91 %) des 11 critiques ont été admis au CHUG.
Conclusion : Cette étude souligne la forte incidence de la traumatologie routière à Marie-Galante. Ce travail doit permettre d’élaborer des axes d’amélioration de PEC, notamment par la filiarisation du patient traumatisé.
