To describe a clinical case and analyze the challenges in diagnosing hypertrophic cardiomyopathy (HCM) in a patient with concomitant arterial hypertension (AH).\u0000Materials and methods. The article presents the clinical case of HCM in the patient with concomitant AH that was observed in an ambulatory setting in the Municipal Enterprise “Dnipropetrovsk Regional Clinical Center for Diagnostics and Treatment” of Dnipropetrovsk Regional Council.\u0000Results. A 66-year-old woman N., diagnosed by her family physician with coronary artery disease (CAD): stable angina FC II, grade 2 AH, chronic heart failure FC II NYHA, was referred to a cardiologist because of experiencing exertional dyspnea, chest pain, and uncontrolled blood pressure despite treatment compliance.\u0000Echocardiography identified concentric left ventricular hypertrophy with the left ventricular outflow tract (LVOT) obstruction (a mean gradient of 35 mmHg as per catheterization). Cardiac MRI confirmed the diagnosis and coronary angiography ruled out CAD. Adjustments to the treatment regimen, taking into account HCM with LVOT obstruction, effectively alleviated the patient’s symptoms and stabilized her blood pressure.\u0000Conclusions. It is especially important to follow the guidelines of AH management and perform echocardiography in all patients with high blood pressure, so as not to miss the signs of concomitant HCM, particularly with LVOT obstruction. In addition, in the case of HCM, it is necessary to timely detect, provide prevention and manage patients at risk for sudden cardiac death. Since HCM encompasses various diagnoses with different pathogenesis and distinct management, cardiac MRI, enzymatic or genetic testing may be needed according to guidelines.\u0000As HCM is a relatively common inherited cardiac disease, general practitioners could often encounter such patients in everyday clinical practice. Hence, they should have a certain suspicion of this diagnosis in persons with AH whose left ventricular mass meets the criteria for HCM.","PeriodicalId":23832,"journal":{"name":"Zaporozhye Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831000","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}

Untimely diagnosis and inadequate treatment of patients with endoprosthesis component loosening leads to major bone defects.\u0000This problem arises from repeated joint interventions, large bone defects and duration of revision surgeries, that is fraught with catastrophic consequences for patients – revision prosthesis removal or even limb amputation. The project aims to improve the treatment for patients with instability of components after knee joint arthroplasty.\u0000The aim of the study is to analyze the results of revision knee arthroplasty and identify the causes of mistakes and complications of revision arthroplasty with the intention of prevention.\u0000Materials and methods. A retrospective analysis of 50 revision knee arthroplasties performed at the Centre for Arthroplasty of the State Institution “Institute of Traumatology and Orthopedics of the National Academy of Medical Sciences of Ukraine” was conducted. Clinical and radiological findings were evaluated for all patients. All revision prostheses used in this study were of the semi-constrained type. Cementation technique was used for all implants. In the revision of the septic complication group, a full cementation technique with antibiotics according to a sensitivity profile were used, while in the aseptic complication group, a surface cementation technique with antibiotics according to sensitivities were used.\u0000Results. The authors of the project have analyzed the results of treatment of 50 revision arthroplasty procedures performed between 2013 and 2022 for instability of the endoprosthesis components. The structure of complications has been examined and the causes of failure in revision knee arthroplasty have been identified. This study has shown promise in preventing complications and developing personalized approaches to revision arthroplasty.\u0000Conclusions. The analysis of revision knee arthroplasty failure has shown the prevalence of septic complications (56.0 %). In the case of septic complications after revision arthroplasty, Staphylococcus aureus prevailed (57.1 %), gram (-) microorganisms were causative agents in other cases. Factors resulting in aseptic complications included those associated with the surgical intervention (81.8 %), the patient (45.4 %) and the combination thereof (72.7 %). Significant causes of the femoral revision component loosening were residual valgus deformity, medial instability in the frontal plane; significant causes of the tibial component loosening were residual varus deformity and lateral instability in the frontal plane.","PeriodicalId":23832,"journal":{"name":"Zaporozhye Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831493","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 inform practitioners with the case of neonatal sepsis, when timely diagnosis and intensive care helped to prevent the development of septic shock and multiple organ failure.\u0000Materials and methods. A child was treated in the Department of Anesthesiology and Intensive Care of Newborns of Zaporizhzhia City Pediatric Hospital No. 5. He underwent clinical and biochemical blood tests, microbiological, radiological and ultrasound examinations using the hospital equipment.\u0000Results. The child with a complicated prenatal history was born by emergency caesarean section for severe pre-eclampsia at 34 weeks’ gestation. On the tenth day of life, the infant developed a worsening intoxication syndrome and febrile temperature. X-ray examinations revealed right-sided pneumonia; clinical blood count showed leukocytosis with acute inflammatory changes, thrombocytopenia, and an elevated procalcitonin level. A day later, the inflammatory changes dramatically deteriorated, and the cerebrospinal fluid cytosis was increased up to 850 cells and dominated by neutrophils. Blood cultures tested positive for Enterobacter cloacae. The child was prescribed antibacterial therapy according to the de-escalation principle (meronem and vancomycin) with subsequent changes according to the results of microbiological examinations, infusion therapy with parenteral nutrition, immunosupportive (intravenous immunoglobulin) and antifungal therapy. As a result of intensive therapy, clinical blood count inflammatory abnormalities were regressed, cerebrospinal fluid was completely restored to health, procalcitonin and C-reactive protein levels were normalized, and pneumonia was resolved within a week. Positive laboratory changes were correlated with the general condition: normalization of body temperature, increased activity, and enteral feeding ability.\u0000Conclusions. Timely diagnosis and intensive care of neonatal sepsis caused by gram-negative flora helped to prevent the development of multiple organ failure and septic shock. The use of antibiotic therapy according to the de-escalation principle is justified in newborns at high risk of developing septicaemia.","PeriodicalId":23832,"journal":{"name":"Zaporozhye Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141829327","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 open prospective study, 165 adolescents (74 boys and 91 girls) with a mean age of 17.5 ± 0.5 years were enrolled. 24-hour ECG monitoring showed increased heart rate >90 bpm in 12 boys and 19 girls considered themselves healthy. All the children were examined according to a program including 24-hour blood pressure monitoring, heart rate variability, serum concentrations of the main hormones, endothelin and copeptin. Health-related quality of life was measured by the SF-36 questionnaire. A physical work capacity test (PWC170) on a bicycle ergometer was evaluated in an 8-month physical rehabilitation program.\u0000Results. Adolescents of both sexes with ST were hypersympathicotonic with humoral dysregulation of the sinoatrial node, grade I arterial hypertension, elevated blood levels of estradiol and osteocalcin and low renin in females.

A total of 44 male participants were divided into three groups based on the IRSA level. The first group included 26 men with an optimal IRSA level. The second and third groups, each of 9 men, with moderate and high IRSA levels, respectively. The functional state of cardiovascular system was assessed using a device “REOKOM” (Kharkiv). The measurement of body composition was performed by weight-scale “TANITA BC-601” (Japan). The functional state of autonomic nervous system was assessed using a device “CARDIOLAB” (Kharkiv).\u0000Results. Our results have demonstrated higher hemodynamic parameters in men with moderate and high level of IRSA. Men with elevated level of sympathetic activity had the highest indices of the pumping function of the heart, and those with the balance between parasympathetic and sympathetic branches had the lowest indices of the pumping heart function. As for the indicators of total peripheral resistance and specific peripheral resistance, another trend was seen, namely, individuals with a balanced state of autonomic nervous regulation had the highest parameters, and those with a predominance of sympathetic tone had the lowest ones. Close correlations have been found between increased levels of regulatory mechanism tension and cardiohemodynamic parameters.\u0000An indicator analysis of the body component composition has revealed a significant increase in body mass index, total and visceral fat content in the examined groups with moderate and severe regulatory system tension. In addition, correlations have been found between IRSA and constituting components of body composition.\u0000Conclusions. The group assignment of the examined individuals according to IRSA has shown that a high tension of the regulatory mechanisms increased the load on the cardiovascular system, as indicated by higher indicators of central hemodynamics.

One of the most important pathogenetic links of rotavirus gastroenteritis is the development of osmotic diarrhea induced by carbohydrate malabsorption syndrome. Its development is associated with disaccharidase insufficiency and impaired absorption of monosaccharides in the small intestine.\u0000Carbohydrate malabsorption syndrome is found in 67.0–98.3 % of children with RVI.

Carbohydrate malabsorption syndrome is observed in the absolute majority of children with RVI, and its maximum severity is noted from the fifth to the seventh day of the disease, being realized mainly due to lactase deficiency. The severity of carbohydrate malabsorption syndrome can be influenced by concomitant pathological conditions, that lead to a decrease in the activity of disaccharidases in the small intestine, and the metabolic activity of the intestinal microbiota.","PeriodicalId":23832,"journal":{"name":"Zaporozhye Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141829998","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 evaluate the treatment results of achalasia cardia by the method of laparoscopic Heller’s cardiomyotomy with Dor fundoplication, we analyzed 30 case histories of patients who were treated in the period from 2011 to 2022. Inclusion criteria were age 18 years or older, diagnosis of stage II, III cardia achalasia confirmed using instrumental examinations. Exclusion criterion was stage I achalasia. The mean age of the patients was 53.0 ± 15.3 years. In terms of sex, this group was almost equal, there were 14 (46.7 %) women and 16 (53.3 %) men. The average duration of the disease was 5.0 ± 1.2 years. To determine the degree of achalasia, we used the radiological classification of the distal esophageal morphology in achalasia and distinguished 4 stages.

This relates not only to the wide occurrence of the infection, but also to a fairly high mortality rate, currently more than 6.5 million deaths in the world.\u0000The aim of this study was to analyze, generalize and systematize the currently available literary data on the study of the novel coronavirus infection pathogenesis in the human body and to determine key changes that occur after the SARS-CoV-2 penetration into cells. In this way to target physicians primarily based on the pathogenetic processes that occur in the human body, syndromes and symptom complexes that are observed in treatments.\u0000Results. The article presents a literature review demonstrating that the specific interaction between the virus and somatic cells is the triggering mechanism for the pathogenesis of coronavirus infection. The main route for SARS-CoV-2 entry into the body is the angiotensin-converting enzyme 2 (ACE2) receptor, which is expressed not only in type 2 alveolar epithelial cells, but also in cells of the kidney, heart, blood vessels and gastrointestinal tract, including endotheliocytes and pericytes. Expression of the ACE2 receptor has also been shown in various structures and parts of the brain, cells of the conjunctiva, limbus, cornea and cells of the substantia propria. A high expression of the ACE2 receptor has been found in the epithelial cells of the oral mucosa, salivary glands, tonsils and tongue. These factors explain a possible involvement of different organs and systems in the development of multiorgan failure.\u0000Conclusions. In the development of multiorgan disfunction, two components are important: first, direct cell tropism and viral load, that may be unique in each patient. Secondly, it is the development of immune-mediated reactions to infected cells. Under conditions of hyperimmune inflammation, that is, the development of cytokine storm, acute respiratory distress syndrome progresses, and multiple organ failure develops. Endothelial damage is directly involved in the pathophysiology of this process, that results in the development of endothelial dysfunction, disruption of microcirculation, as well as perivascular inflammation, which aggravates damage to the endothelium and can lead to thrombus formation.\u0000The use of modern knowledge about the immunopathogenesis of COVID-19 would help to estimate the risk for severe infection and the possible development of complications, allowing for the timely implementation of effective pathogenetic therapy.","PeriodicalId":23832,"journal":{"name":"Zaporozhye Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141830170","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}
