The problems of teenage pregnancy are extremely relevant in Ukraine: in ten years, almost 100,000 girls aged 16–17 became mothers, solving the problems of teenage births. The urgency of the problem of pregnancy in young girls gives grounds to consider and treat this issue as a serious social and psychological problem that requires further study and development of measures to prevent it.\u0000The purpose of the research is to study the state of reproductive health in young women among the population of Lviv region, determining the frequency of adolescent pregnancy and taking into account the contribution of gynecological pathology and menstrual disorders.\u0000A retrospective analysis of the primary medical records of 134 young women was conducted. We studied the frequency of adolescent births, social status, medical surveillance coverage during pregnancy, reproductive history in adolescent women for 4 years in Lviv Regional Clinical Hospital.\u0000Analysis of the prevalence of adolescent pregnancy showed that the frequency of childbirth in young women remained stable for four years: in 2014–2017, in the maternity wards of Lviv Regional Clinical Hospital, 134 women under the age of 18 gave birth, which is 0.82–0.98% of the total number of births.\u0000A significant majority (p <0.05) of them (78 women) were 17 years old (that is 58.2%) and 84 women lived in rural areas (62.7%); 97 women were not married (72.4%). Only 1/3 (34.3%) of young women were registered in a women's clinic before 12 weeks of pregnancy, and 10.4% of them were not followed up by doctors at all during pregnancy. The study of menstrual dysfunction, namely irregular menstruation, showed the presence of this indicator in more than 1/2 (80–59.7%) out of 134 young women. According to the results of the study, despite their young age, 127 (94.8%) of 134 women were pregnant for the first time, and 7 (5.2%) women had consecutive pregnancy. Among 7 (5.2%) women who had consecutive pregnancy, only 4 (3.0%) had an uncomplicated pregnancy, and three (2.2%) subjects had a history of one (0.7%) silent miscarriage, premature birth, medical abortion. More than 1/3 (50–37.3%) of young women gave birth to children with poor health. The most common cause of reproductive disorders in young women of the main group was prematurity of newborns (37.3%). The data obtained indicate the feasibility of studying adolescent motherhood, which will be especially valuable in the context of developing effective demographic policies.","PeriodicalId":315243,"journal":{"name":"Eastern Ukrainian Medical Journal","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127192731","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}

In the literature review, the modern perspective of children’s hormonal state in bronchopulmonary diseases is studied. The hypothalamus-hypophysis-thyroid and hypothalamus-hypophysis-paranephros interaction roles in bronchopulmonary adaptive responses are explained. The thyroid hormone and cortisol importance for organism resistance are regarded. The manifestation, pathogenetic progress mechanisms, diagnosing methods, and treatment of different subclinical hormonal shifts (particularly euthyroid sick syndrome) are researched. The interconnection of hormonal and immunological indicators is covered (whose change is a predictively significant marker – that can foresee the disease progress, its duration and consequences for patients).

The doctor often faces the question of how to objectively assess the clinical picture of bronchitis, and now the assessment of respiratory symptoms is often based on criteria such as cough, shortness of breath or wheezing on auscultation. However, today there are practically no data on the severity of bronchitis in children depending on the above criteria.\u0000A cohort of 158 children with bronchitis was created at the pulmonology and allergology Department of the Municipal Medical Institution \"Regional Children's Clinical Hospital\" in Chernivtsi. The severity of bronchitis was assessed at the beginning and on the 3rd and 7th day of inpatient using the Bronchitis Severity Score (BSS). According to this scale, mild bronchitis was verified in 30 patients which formed the I clinical group, and 128 children had moderate bronchitis (II clinical comparison group).\u0000Aggressive inflammation of the bronchi in children with moderate inflammation of the bronchial tree compared with patients with mild bronchitis was accompanied 1.6 times more often by recurrence, a history of episodes of community-acquired pneumonia in 9.4% of patients, long-term inpatient treatment (odds ratio 2.6) and halving the duration of the outpatient treatment period. The study of clinical severity of bronchitis in children of the comparison groups made it possible to establish an increase in the chances of a more severe course of the disease on the 7th day of hospitalization in children with moderate bronchitis (odds ratio 4.8) with persistence of cough in 68.7% of children in this group (odds ratio 3.8). Evaluation of inpatient treatment tactics indicated the need to increase the volume of complex therapy in patients with moderate bronchitis relative to children with mild disease (odds ratio 12.0, relative risk 8.8), as well as increasing the risk of the need for antibacterial therapy (odds ratio 3.7, relative risk 2.8) and the appointment of intravenous antibiotics for more than 3 days (odds ratio 5.0, relative risk 1.1).","PeriodicalId":315243,"journal":{"name":"Eastern Ukrainian Medical Journal","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128600869","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}

Although, there are numerous types of glucose-lowering drugs that exhibit anti-diabetic effects but results of treatment in patients are still not so perfect. Therefore, many treatments that include the use of medicinal plants are suggested and encouraged. Medical plants are believed to contain chemical substances with potential curative effects and can often have anti-diabetic effects. This study introduced about 23 effective medicinal plants reported by various experimental researchers with the curative potential to treat diabetes. Although, most of the research used animal models, there is a clear indication that medicinal plants with anti-diabetic potentials are being investigated by several researchers. However, there is a need for further research to be conducted with isolated bioactive ingredients present in these plants in order to have potential ingredients that could be used as a pharmacological agent in the treatment of diabetes mellitus with fewer adverse effects. Again, the mechanisms of action of these medicinal plants in ameliorating diabetes need to be investigated.","PeriodicalId":315243,"journal":{"name":"Eastern Ukrainian Medical Journal","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125606743","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}

According to our data, up to 40% of patients sought specialized care for more than 6 months after the injury, and 19.9% were treated conservatively for an unreasonably long period of time. It led to an increase in the portion of unsatisfactory treatment results, since the prognosis of the further functional and useful degree of nerve recovery worsens with increasing time after injury.\u0000\u0000 The main objective was to select the optimal option of biocompatible material for implementation in practice in case of traumatic peripheral nerve damage.\u0000\u0000Materials and methods. The analysis of medical literature for 2015–2020 was conducted. First of all, it should be noted that modern non-biological resorbable tubes are made of polyglycolic and polylactic acids. Non-resorbable tubes, including silicone, have shown undesirable effects, including axon compression during regeneration and the reaction of a fibrous foreign body. Hollow cylindrical tubes can be manufactured in several ways, such as electrospinning, crosslinking, physical film rolling, injection molding, melt extrusion, and braiding.\u0000Adequate surgical treatment of peripheral nerve injuries requires that the surgeon, in addition to an accurate knowledge of the anatomical details of the affected area, would also be familiar with microsurgical methods and had necessary equipment to operate. The main procedure in peripheral nerve surgery is the restoration of nerve continuity, which can be obtained by direct coaptation between the two ends of a severed nerve or by the introduction of nerve grafts to replace a defect in nerve tissue.\u0000Polyester is the most common synthetic material used in neural tissue engineering, along with polylactic acid, polycaprolactone, and polyglycolic acid. In combination with mesenchymal stem cells of the bone marrow, polylactic acid showed better results and accelerated the recovery of peripheral nerves. Polylactic acid directed the migration of Schwann's cells and induced the formation of a normal nervous structure. It was proved that the polycaprolactone material had an effect similar to that of autografts in nerve repair, and its characteristics were better than in a polylactic acid tube. Polyglycolic acid also possesses sufficient mechanical properties and can be used to repair a nerve defect. Artificial synthetic materials have good biocompatibility and biodegradability with minimal toxicity. For the production of high-purity polymer monomers, which are necessary for the manufacture of the frame, much time and financial costs are required.

Differential diagnostics of different tumor subtypes for prognosis and treatment is necessary given that some of them, like renal cell oncocytomas, are benign, and others, like chromophobe renal cell carcinomas, are malignant. Unfortunately, the histological similarity between these tumors makes accurate diagnostics difficult. In some cases, additional diagnostic methods such as immunohistochemistry should be used. The aim of our study is to analyze the histological characteristics of chromophobe renal cell carcinomas and renal oncocytomas, in order to specify their pathognomonic features, allowing for the confirmation of the diagnosis.\u0000\u0000Materials and methods. We used data from histories of disease and histological postoperative material of 198 patients with chromophobe renal cell carcinoma and renal oncocytoma. After the diagnosis was confirmed, we described the histological features of the tumors and calculated their relative prevalence amongst the renal oncocytoma and chromophobe renal cell carcinoma tissues. To conclude, we identified the histological features that are more likely to be present in the case of chromophobe renal cell carcinoma.\u0000\u0000Conclusions. Chromophobe renal cell carcinomas are present in 31 % of our samples. Tumors are more prevalent in patients in their sixth and seventh decade. Most chromophobe renal cell carcinomas are unilateral.\u0000\u0000Chromophobe renal cell carcinomas have a polymorphic histological structure. The classic variant of chromophobe renal cell carcinoma is more common than the eosinophilic one. A mixed variant of chromophobe renal cell carcinoma is present in a minority of cases. The most common features of ChRCC are solid and alveolar growth patterns, clear and reticular cytoplasm, raisinoid nuclei.\u0000\u0000After comparing the relative prevalence of various histological features in renal oncocytomas to those present in chromophobe renal cell carcinomas, we are able to ascertain that chromophobe renal cell carcinomas tend to exhibit the following features significantly more often than renal oncocytomas: differing nuclear size, raisinoid nuclei, reticular cytoplasm, clear cytoplasm.\u0000\u0000The particular features mentioned in the preceding paragraph, can be present on a small subset of the tumor tissue, and are thus, often missed during analysis, which can lead to misdiagnosis.
