Endometrial hyperplastic processes take an important place among the gynecological diseases in women of various ages and are one of the most common reasons for admission at inpatient gynecology departments. The urgency of the pathology is due to the significant prevalence of endometrial hyperplastic processes, high incidence of malignancy, prolonged relapsing course, and decreased reproductive function, since these diseases are one of the most common causes of infertility in women of childbearing age. The statistics related to the incidence of endometrial hyperplastic processes in Ukraine is not available. An analysis of case histories and medical records showed that in 40% of cases, endometrial hyperplastic processes were asymptomatic. In 60% of cases, the clinical manifestations of endometrial hyperplastic processes were menstrual disorders, such as dysmenorrhea, oligomenorrhea, menorrhagia, and metrorrhagia. In 30% of cases, endometrial hyperplastic processes were recurrent. The most common concomitant pathologies of the pelvic organs were uterine leiomyoma and endometriosis; the most common concomitant extragenital diseases were hypertension and obesity. Our study and data analysis showed that there is an increasing trend in the incidence of endometrial hyperplastic processes in Sumy region in 2011–2020. The maximum incidence was in 2016. A correlation was found between hyperplasia incidence and age. Thus, the largest number of non-atypical and atypical endometrial hyperplasia cases was observed in women aged 45–55 years. The lowest number of non-atypical endometrial hyperplasia cases was registered in women aged 66+, while atypical hyperplasia cases – in women under 30 years of age. Glandular polyps of the endometrium were most often diagnosed at the age of 31–44; the lowest number of these was found in women over 66 years. Most glandular-fibrous endometrial polyps were observed in women aged 45–55 years, while women under 30 presented with the fewest cases. Fibrous endometrial polyps were most common in older age groups – 66+; the lowest number of such endometrial polyps was found in women under 30 years. We attributed the decreased incidence of endometrial hyperplastic processes in 2020 to the quarantine measures introduced, which, as a consequence, led to the decreased number of diagnosed cases, since they are often asymptomatic.

Introduction. Parkinson's disease (PD) is a neurodegenerative neurological disease with a slowly progressive course. In particular, it manifests as a movement disorder that includes rest tremor, rigidity, bradykinesia, and postural instability. Movement disorder in patients with PD mainly occurs due to the selective loss of pigmented dopaminergic neurons of the compact area of the substantia nigra, as a result of the depletion of dopamine in the striatum. The pathogenetic feature of this disease is the presence of intraneuronal aggregates and inclusions of α-synuclein. To date, there are no proven treatments for Parkinson's disease, but a number of medications exist offering benefits in terms of controlling movement disorders. Although they can significantly improve motor function, they can also lead to problematic side effects, especially as the disease progresses. Materials and methods. To analyze the main directions of modern methods of Parkinson's disease treatment and to conduct a profound review and analysis of literature research data on the modern methods of Parkinson's disease treatment over the past 10 years. The results. It has been established that modern treatment methods are based mainly on exogenous administration of drugs with dopaminergic activity and inhibitors of endogenous dopamine metabolism. Although levodopa has been used in the treatment of Parkinson's disease since its inception, numerous experimental therapeutic and neurosurgical approaches are now being investigated. These include drugs aiming at the inhibition and degradation of α-synuclein aggregation, which is considered the driving force of neurodegeneration in Parkinson's disease. They raise expectations that a disease-modifying agent will be discovered in the short-term future. Thus, in combination with a number of regenerative and neurosurgical approaches, including stem cell and gene therapy and deep brain stimulation, significant progress will be made in the treatment of Parkinson's disease in the coming years and a number of new effective options will become available.

The article discusses and analyzes literature data on the phenomenon of fatigue in patients with multiple sclerosis. More than 80% patients with multiple sclerosis complain of fatigue, which significantly limits their functional capacity and negatively affects the quality of life. In general, fatigue is a complex, multidimensional phenomenon that consists of subjective (one's own feeling of fatigue) and objective (quantitative characteristics of fatigue when performing a certain activity) components. At present, the most accessible method of fatigue assessment is patient survey. In multiple sclerosis, fatigue can be primary (as a direct consequence of the disease) or secondary (as a consequence of reduced functional capabilities, sleep disorders, chronic pain, side effects of medications, etc). In general, fatigue in multiple sclerosis is a heterogeneous phenomenon based on various etiopathogenetic mechanisms. We reviewed neuroimaging markers of global and focal lesions of the white and gray matter of the brain that are associated with the presence of fatigue in patients with multiple sclerosis. The impact of peripheral immune-inflammatory processes on the fatigue occurrence was shown which was realized via humoral, cellular, and neuronal mechanisms. We analyzed the role of inflammatory processes in the brain and spinal cord in the form of activation of microglia with hyperproduction of cytokines, which ultimately disrupts dopamine metabolism and reduces the affinity of dopamine receptors. The excess activity of certain functional components of the nervous system in the form of higher engagement of the motor structures of the brain and spinal cord during the performance of standard motor tasks was highlighted. The role of disruption of interoceptive mechanisms (perception and monitoring of the body's internal environment via hormonal, immune, metabolic, temperature, pain, and visceromotor signals) in the occurrence of fatigue in multiple sclerosis was shown. The paper underlines modern principles of fatigue correction based on these mechanisms.

Viral infections with aerosol transmission are one of the most common infectious diseases in the world. Their relevance is due to the wide distribution and socio-medical consequences. To study the dynamics of the incidence of viral infections with aerosol transmission in Sumy Oblast, to determine the level of influence of social and natural factors on the intensity of the epidemic process. Data from the sectoral statistical reporting of the Ministry of Health of Ukraine, Sumy Regional Laboratory Center, the Main Department of Statistics in Sumy Oblast, Sumy Regional Center of Hydrometeorology were used. Epidemiological and statistical research methods were used. It was established that in Sumy Oblast the epidemic process of aerosol viral infections was characterized by a pronounced tendency to reduced incidence of influenza (Rinc.aver.= -6.2 %) and rubella (Rinc.aver.= -22.7 %), moderate reduction tendency ‒ to mumps (Rinc.aver = -2.4 %); high intensity with no reduction in incidence ‒ for other acute respiratory diseases (Rinc.aver = 0.2 %); a sharp increase in the incidence of measles (Rinc.aver.= 23.1 %). Coronavirus infection caused by SARS-CoV-2 was found in 3% of the population. The average long-term rates of measles, rubella, and mumps vaccinations with MPR-1 and MPR-2 vaccines were 70.9 % and 61.2 %, respectively. An inverse correlation was established between air humidity, population, coefficients of natural and migratory movement and measles incidence (p<0.05). The system of epidemiological surveillance of infections of viral etiology with aerosol transmission requires new approaches to the development of preventive measures.

Objective: to summarize the main facts of M. M. Terekhovskyi’s biography based on a critical analysis of publications and, at the same time, to highlight his contribution to the improvement of teaching in higher medical school. Materials and methods. Published materials were used as historical sources. The historical method was the main research method in the article. Results. We performed an analysis of the literature about prof. Terekhovskyi. For the first time, his role in the reforms of higher medical education in the late 18th – early 19th centuries was clarified. The first critical analysis of the literature about M. M. Terekhovskyi, published over more than a century and a half, made it possible to identify erroneous statements and typos. It was found that the first publication about him appeared in 1845, that is, half a century after his death. It was a brief biographical note in the dictionary of Metropolitan Eugene. It was proved that the main and most complete life description of Professor Terekhovskyi was his biography written by Ya. A. Chistovich (1883), which was based on archival materials and supplemented with archival findings by M. K. Borodii (1984). The fundamental study of his contribution to science was represented by the work of S. L. Sobol (1948, 1963). It was shown that the charter of 1792 of the higher medical school (academy), which Professor Terehovskyi took part in, served as the basis for the staff of the St. Petersburg Medical and Surgical Academy in 1808. The charter of 1792 for the first time included Medical Police (Politia Medica), which was later transformed into Social Hygiene and Public Health, as one of the teaching subjects in the higher medical school. Then it was enshrined in the charter of 1806, which was written by the founder of this science, J. P. Frank. The study made it possible to identify gaps in the biography of M. M. Terekhovskyi. Thus, the date and month of his birth are still unknown; it is not clear who his mother was, whether he had his own family (wife, children), and whether he received a scholarship from Princess Ye. D. Golitsyna. With this regard, further archival searches are needed to confirm Professor Terekhovsky’s authorship of the handwritten essay «Opinion on the correction of medical sciences.»
目的:在对出版物进行批判性分析的基础上，总结捷列霍夫斯基传记的主要事实，同时突出他对改进高等医学院教学的贡献。材料和方法。出版的材料被用作历史资料。历史研究方法是本文的主要研究方法。我们对捷列霍夫斯基教授的文献进行了分析。他在18世纪末至19世纪初高等医学教育改革中所扮演的角色第一次被阐明。对捷列霍夫斯基(M. M. terekhovsky)的文献进行的第一次批判性分析发表了一个半多世纪，使人们有可能发现错误陈述和错别字。人们发现，关于他的第一本出版物出现在1845年，也就是他死后半个世纪。这是尤金大都会的字典里的一篇简短的传记。事实证明，对捷列霍夫斯基教授生平最主要、最完整的描述是雅所著的传记。A. Chistovich(1883)，它以档案材料为基础，并补充了M. K. Borodii(1984)的档案发现。他对科学贡献的基础研究以S. L. Sobol(1948, 1963)的工作为代表。据证明，捷列霍夫斯基教授参加的1792年高等医学院(学院)章程是1808年圣彼得堡医学和外科学院工作人员的基础。1792年的《宪章》第一次将医学警察(Politia Medica)纳入其中，后来转变为社会卫生和公共卫生，作为高等医学院的教学科目之一。然后，它被写入了1806年的宪章，该宪章是由这门科学的创始人j·p·弗兰克撰写的。这项研究使人们有可能找出捷列霍夫斯基传记中的漏洞。因此，他的出生日期和月份仍然是未知的;不清楚他的母亲是谁，他是否有自己的家庭(妻子、孩子)，以及他是否获得了叶公主的奖学金。d .

Background. Hyaline fibromatosis syndrome is a rare, highly dramatic, autosomal recessive multisystem disorder. The basis of the disease is the abnormal diffuse deposition of hyaline material in the connective tissue and internal organs. Mutations in the CMG2 gene (also known as the ANTXR2 gene) cause the disease. CMG2 encodes a transmembrane protein involved in endothelial development. Hyaline fibromatosis syndrome involves two allelic diseases that have the same phenotype. These are infantile systemic hyalinosis and juvenile hyaline fibromatosis. Common signs of these diseases are pain, joint contractures, skin lesions (thickening of the skin with areas of hyperpigmentation, pearl-sized nodules or papules), subcutaneous nodules on the head, neck, and extremities, gingival hypertrophy, osteopenia, protein-losing enteropathy, increased susceptibility to infectious diseases. Diseases differ in the time of the first clinical signs onset, the severity of the course, and the life expectancy of patients. In the case of infantile systemic hyalinosis, the prognosis is fatal. Hyaline fibromatosis syndrome is an orphan disease that is very difficult to diagnose. There is no pathogenetic treatment for the disease today. Clinical case. We described a case of hyaline fibromatosis syndrome in a boy who was observed and treated at the Municipal Non-Profit Enterprise of Sumy Regional Council "Regional Children's Clinical Hospital" (Ukraine). The diagnosis was made based on medical and genetic analysis. The early manifestation of symptoms and the severe course of the disease forced us to think about infantile systemic hyalinosis in the child. Along with characteristic external phenotypic signs, severe enteropathy with protein loss and persistent infections were observed in the child. As far as we know, this is the first case of the disease diagnosed in Ukraine. This publication aims to draw medical professionals' attention to the diversity of the course of genetic diseases in children. Comprehensive care, timely and symptomatic treatment make it possible to prolong the life of patients.

Some patients with stage 1 arterial hypertension often have symptoms originating from various anatomic and functional locations in the absence of organic changes associated with manifestations of psychosomatic autonomic dysfunction. Among the manifestations, patients have "respiratory", cardiovascular, abdominal symptoms, as well as the signs of anxiety-depressive syndrome. These signs indicate the presence of comorbid psychosomatic disorders in the patient, which can affect the course of hypertension and the nature of the treatment. Materials and methods. The screening was carried out in 125 patients with stage 1 AH. Hyperventilating syndrome was detected in 46.40% of them (n = 58) according to the Nijmegen questionnaire; these patients were included in the experimental group. At the same time, standard indicators of hemodynamics, state of anxiety as an additional marker of psychovegetative dysfunctions according to the Spielberger scale were evaluated. The control group consisted of 24 patients with stage 1 AH without signs of hyperventilating syndrome. By randomization, all patients of the experimental group were divided into 4 groups depending on the treatment: patients from 1st and 2nd group received perindopril and amlessa; 3rd and 4th group – medication in combination with systematic diaphragmatic breathing. The latter provides an anti-stressor effect, normalizes the breathing pattern, eliminates the consequences of hypocapnia and possibly reduces the effect of bradykinin on bronchial tone after taking ACE inhibitors. Results and discussion. A correlation was found (r = 0.72; p ˂ 0.05) between the severity of hyperventilating syndrome (41.63 ± 0.82) points and indicators of total peripheral vascular resistance (1476.13 ± 42.39) dyn•s•cm-5. The latter was significantly higher than the results obtained in the control group of patients – (1374.62 ± 36.11) dyn•s•cm-5 (р ˂ 0.05). At the same time, the signs of state anxiety comprised (42.96 ± 2.05) points vs. the result in the control group (22.36 ± 1.33) points (р ˂ 0.05). The evaluation of the results of the treatment after 2–3 months revealed a significant advantage of the combined effect of medications and systematic diaphragmatic breathing, which reduced hyperventilation in the 3rd and 4th groups by 12.92% and 15.37% (р ˂ 0.05); state anxiety by 16.73% and 20.31% (р ˂ 0.05), respectively, which was not significant in groups 1–2. In addition, diaphragmatic breathing increased the effect of amlessa. When treating patients with stage 1 hypertensive disease it is recommended to search for the signs of hyperventilating syndrome and prescribe combined therapy which includes diaphragmatic breathing and hypotensive medications.

Introduction. The COVID-19 pandemic and the resulting decline in social communication have negatively affected many people’s mental health, especially young people. This research aimed to investigate the mental health of Sumy State University medical students during the Covid-19 pandemic. This study was conducted from September 2020 to May 2021. Materials and Methods. The second-year students of the Academic and Research Medical Institute of Sumy State University participated in the study – 100 female and 100 male students. The average age of the students was 18–22 years. The mental health of the medical students was examined using the Goldberg General Health Questionnaire (GHQ-28). The total scores for mental health, psychosomatic symptoms, anxiety, insomnia, social dysfunction, and depression were investigated. The experimental data were analyzed using PAST statistical software v4.05. The research was conducted in compliance with the WMA Declaration of Helsinki’s “Ethical Principles for Medical Research Involving Human Subjects” after obtaining consent from all participants. Results and Discussion. It was found that the COVID-19 pandemic caused mental health disorders in 63.5 % of medical students. There was no significant difference in the total GHQ score (> 8) between men and women. Social dysfunction occurred to be the most common mental health disorder in medical students. Somatic symptoms, anxiety, social dysfunction, and depression were observed in 37.5 %, 49 %, 64 %, and 14 % of medical students, respectively. The prevalence of social dysfunction and depression was higher in men than women. Conclusion. It was established that men experienced more significant disturbances in mental health than women during the COVID-19 pandemic.

Objective of the research: to investigate the efficacy and safety of Afobazole in the treatment of adult patients with anxiety disorders and metabolic syndrome X. The study included 60 adult patients (18–65 years) (36 men, 24 women), whose clinical picture revealed mild and moderate forms of neurotic disorders observed in the therapeutic hospital and outpatient service. The main group (30 people) and control group (30 people) were formed on the basis of representativeness by gender and age (χ2emp <χ2krit, p ≤ 0.01). The sample consisted of patients who signed a written informed consent to participate in the study. The average age of the patients in the control group was 44.81 ± 2.17, in the main group – 45.13 ± 2.34 (p < 0.01); the average age of onset of mental disorders in the main group was 33.2 ± 3.1 years; in the control group it was 34.1 ± 3.4 years (p < 0.05); the average duration of psychopathological symptoms in the main group was 5.6 ± 0.6 months, in the control group – 5.8 ± 0.3 months (p < 0.05). The duration of treatment equaled 1 month of active therapy (later, the patients were transferred to maintenance therapy outside this study). Afobazole containing 0.01 g of active substance per tablet was used for treatment. The drug was prescribed 3 times a day (morning, afternoon and evening); the dose of the drug was increased: 1–1–2 (number of tablets per administration). There were changes in psychometric scaling, i.e. a significant decrease in state (by 57.2 and 42.9%; p ≤ 0.001) and trait (by 23.8 and 23.3%; p ≤ 0, 01) anxiety on the Spielberger–Khanin scale in the main and control groups at the end of treatment. In all groups of patients, we noted complete recovery (38.4%) or a significant improvement (37.9%); for most patients with mild manifestations, complete recovery was observed in 92% of cases. Among patients with moderate manifestations, a good response was recorded in 75% of cases; for the rest, moderate and minimal effects were observed, respectively. The changes in the severity as compared with baseline values were significantly positive (p < 0.05) already after 7 days of Afobazole therapy; similar changes were noted in the indicators of the overall effectiveness of therapy. No positive changes after Afobazole therapy were observed in 3.3% of cases, deterioration was registered in 3.3% of cases, while in the control group these values were 6.6% and 3.3%, respectively. The changes in somatic indicators also had positive trends in the control and main groups – SBP reduced by 11.0% and 18.0%, respectively (p ≤ 0.05); DBP – by 4.4% and 14.9% (p ≤ 0.05). The therapeutic effect of Afobazole is the reduction of viscero-vegetative manifestations of anxiety disorders, including relief of breathing, normalization of blood pressure and heart rate, reduction of muscle tension and pain, sweating and dizziness.

The objectives of the study was to compare the depth of polymerization of flowable photocomposite dental restorative materials for bulk fill tooth restorations in laboratory. Materials and methods. Three flowable bulk fill photocomposite dental restorative materials – "SDR® Posterior Bulk Fill Flowable Base," "Filtek™ Bulk Fill Flowable" and domestic "Jen-Radiance Molar-FW" – were chosen for the study. For each material, 10 black opaque thin-walled polyvinyl chloride molds with a length of 10.00 mm and a diameter of 3.00 mm were prepared. The molds were air-dried from a compressor and fixed in fluoroplastic retainers perpendicular to the metal opaque surface below and subsequently filled with the investigated restorative material along the entire length, in a contact manner, along the wall. After filling, the material was polymerized with an LED photopolymerizer directly in contact with the surface of the light guide for 40 seconds. Subsequently, the material was removed from the forms and the remains of the unpolymerized mass were removed from the surface of the polymerized cylinder of the composite with a metal dental sickle-shaped carrier (scarification test). The length of the polymerized cylinder was measured using an electronic micrometer. Results. Therefore, the study of the depth of polymerization of flowable bulk fill photocomposites "SDR® Posterior Bulk Fill Flowable Base", "Filtek™ Bulk Fill Flowable" and domestic "Jen-Radiance Molar-FW" showed that signs of polymerization of all three materials were observed in a depth of more than the "declared" four millimeters which may be explained by the improvement of the recipe for the preparation of such materials and the optimization of the transparency of the organic component and inorganic filler, as well as the regular distribution of photoactivators in the mass. "SDR" polymerized to a depth of 7.38 ± 0.17 (M = 7.30) mm, the minimum value was 7.16 mm and the maximum value was 7.71 mm. "Filtek Bulk Fill Flowable" polymerized to a lesser depth – on 6.34 ± 0.14 (М = 6.38) mm, the minimum value was 6.05 mm and the maximum value was 6.55 mm. The domestic analogue "Jen-Radiance Molar‑FW" showed even higher values of polymerization depth – 8.03 ± 0.19 (М = 7.98) mm, the minimum value was equal to 7.75 mm and the maximum value was 8.41 mm. Statistical tests showed probable similarity between "SDR" and "Jen-Radiance Molar-FW" in the depth of polymerization. Conclusions. All three studied flowable bulk fill photocomposite materials were polymerized to a depth greater than 4.00 mm. Domestic "Jen-Radiance Molar-FW" was similar to "SDR" according to the investigated feature.
