Objective. To compare the effectiveness of laser discectomy and radio-frequency nucleoplasty in patients with nonsequestrated disc herniations accompanied with lumbar osteochondrosis. Material and Methods. Radio-frequency nucleoplasty and laser discectomy were performed in patients from 24 to 57 years old with nonsequestrated disc herniations. Thirty patients who underwent radio-frequency nucleoplasty (main group) and 30 patients after vaporization (control group) were included in the study. Groups were similar in age, gender, concomitant diseases, hernia localization and duration of illness. Pre- and postoperative examination consisted of clinical, radiological, CT and MRI data. The outcomes were assessed in two-three days, one month and 6 months after operation. Results. In two-three days all patients of both groups reported absence of pain or its significant reduction in the lumbar spine or lower extremities. In 6 months 5 patients of a control group suffered of lumbar spine and lower extremities pain, which restricted their labor ability and demanded inpatient treatment. In a main group only 2 patients demanded inpatient care for the reasons given above. Conclusion. The assessment of two technologies suggests that radio-frequency nucleoplasty is a safety technique for treatment of patients with disc herniation accompanied with osteochondrosis. It has obvious advantages over laser intervention.

Results of randomized prospective study with participation of 94 patients aged from 20 to 70 years with monosegmental lumbar spine lesions are presented. Minimum invasive surgical interventions were performed in 55 patients from the main group. Control group consisted of 39 patients in whom decompressive-stabilizing operations via conventional posteromedian approach with skeletization of posterior segments of vertebral column were performed. Average size of operative wound in open interventions more than 10 times exceeded that size in minimum invasive interventions and made up 484 ± 56 and 36 ± 12 sq.cm, respectively. Mean blood loss was 326.6 ± 278.0 ml in the main group and 855.1 ± 512.0 ml in the comparative one. In the main group no one patient required substitution hemotransfusion, while in 13 patients from the comparative group donor erythrocytic mass and/or fresh-frozen plasma were used to eliminate the deficit of blood components. Intensity of pain syndrome in the zone of surgical intervention by visual analog scale in the main group was lower than in comparative group. In the main and comparative groups the duration of hospitalization made up 6.1 ± 2.7 and 9.7 ± 3.7 bed days, respectively. In no one patient from the main group complications in the zone of operative wound were noted. Three patients from the comparative group required secondary debridement and in 1 patient early deep operative wound suppuration was observed. Application of low invasive surgical techniques for the treatment of patients with degenerative lumbar spine lesions enabled to perform radical surgical treatment with minimal iatrogenic injury. The method possessed indubitable advantages over the conventional open operations especially intraoperatively and in early postoperative period.

Aim To evaluate dynamics of biomarkers for endothelial dysfunction (ED), including endothelin-1 (ET-1) and von Willebrand factor (VWF) in patients with stomach cancer (adenocarcinoma) before and after polychemotherapy (PCT); to compare these results with respective values in healthy volunteers and patients with cardiovascular diseases (CVD); to study correlations of the ED biomarkers with indexes of instrumental evaluation of endothelial dysfunction.Material and methods The study included 75 participants, including 25 healthy volunteers (control group), 25 patients with documented CVDs (arterial hypertension + ischemic heart disease), and 25 patients of the main group with histologically documented stage II-IV stomach cancer (adenocarcinoma) who received different courses of PCT with platinum-based agents (oxaliplatin, cisplatin) and fluoropyrimidines (5 fluorouracil, capecitabin). Laboratory measurement of ED biomarkers, computerized nailfold video capillaroscopy (CNVC), and finger laser photoplethysmography (PPG) (methods for noninvasive evaluation of vascular wall and ED), electrocardiography, 24-h ECG Holter monitoring, and echocardiography (EchoCG) were performed for all patients of the main group prior to PCT and within one months after the last course completion. This evaluation was performed once for healthy volunteers and patients of the CVD group upon inclusion into the study.Results In the main group, ET-1 levels were non-significantly lower than normal and did not change during the courses of antitumor treatment (0.95 [0.6; 1.4] and 0.94 [0.7; 1.4] pg /ml (р<0.9) before and after PCT, respectively). Statistically significant differences were found between the control group and oncological patients after the treatment (р<0.04). Levels of VWF remained within the normal range in all examined participants and did not significantly differ between study groups, including oncological patients before and after the specific treatment (р>0.05 for all comparisons). The correlation analysis detected significant correlations of ET-1 levels with functional disorders of microcirculation, ET-1 with the occlusion index (rs=0.56; p=0.005), ЕТ-1 with percentage of capillary restoration (PCR, rs= –0.72; p=0.018) and with the incidence rate of supraventricular extrasystole (rs=0.48; p=0.032).Conclusion The dynamics of ED biomarkers was studied for the first time in patients with stomach cancer receiving a specific antitumor therapy. Although no significant changes in ЕТ-1 and VWF were observed during the PCT (probably due to exhaustion of the endothelial system and a small patient sample), these indexes can be considered as early vasculotoxicity markers due to the presence of significant correlations with indexes of impaired endothelial function according to the results of instrumental evaluation.

The extreme manifestation of atherosclerotic lesion of the arteries of the lower extremities is the critical ischemia of the lower extremities. The number of high amputations in such patients ranges from 120 to 500 per 1 million population in the general population annually. In order to achieve the best results in the patency of the arterial bed in the near and distant periods, revascularization of the arteries of the proximal and distal blood flow is necessary. The aim of the work was to evaluate the possibilities and effectiveness of endovascular, open and hybrid arterial interventions on the lower extremities, particularly in patients with multilevel arterial disease, by conducting a retrospective analysis of treatment of critical ischemia. The results of the preoperative ultrasound duplex scan (UDS) of the arteries of 212 patients with critical ischemia of the lower limbs (CILL) shoved, that in 78 (36.8%) were multilevel arterial lesions (MLAL). Patients were divided into two groups. The first (main group) consisted of 50 patients (64%), who have been restored to the open-end and endovascular methods of MLAL, or only endovascular. The second (control) group included 28 patients (36%) — with restoration of permeability of the proximal segment without intervention on the arteries of the distal. Installed, during the period of 16 months, postoperative observation of 78 patients with MLAL, the primary frontal area of the femoral reconstruction in the main group was 92%, and limb preservation - 96%. In the control group, the permeability of the reconstruction zone was 75%, limb preservation — 82%. Thus, it has been established that the most optimal method of recovery of inflow and outflow pathways is one-time hybrid surgical interventions performed in 88% of these patients, which allow to achieve more effectively the recurrence of ischemia and maintain limb.

The objective: peculiarities of pregnancy in women with common worm infestations in Baku. Materials and methods. During the period from 2015 to 2017, 152 women with common worm infestations were examined, in the gestation period from 16 to 40 weeks in the age group from 18 to 38 years. Depending on the nature of the infestation, 2 main groups were formed: the 1st main group included 84 women who had monoinvasia of helminths, and the 2nd main group included 68 women who had mixed helminth infestation. The control group consisted of 42 women who were pregnant without helminthiasis. All women were examined at 16–22, 23–29, 30–36 and 37–40 weeks of pregnancy. Helminthosis diagnostics was performed by detecting helminth eggs in faecal smears, pinworm eggs in scraping from perianal folds, and visual detection of helminth eggs or pinworms in faeces and vomit. Results. Common symptoms of early toxicosis are nausea, hypersalivation, and vomiting. A rare form of morning sickness treat dermatosis pregnant women, pregnant bronchial asthma, tetany, acute yellow atrophy of the liver, osteomalacia. Symptoms of toxicosis were evaluated in 152 pregnant women. The main symptoms of early toxicosis–nausea, hypersalivation and vomiting–were more common in pregnant women with helminthiasis than in women of the control group. In women with helminthiasis, a symptom complex similar to the manifestations of early toxicosis may persist throughout pregnancy, despite ongoing toxicosis therapy. Since persistent nausea and vomiting can be etiologically caused by helminthic-protozoic intoxication, the frequency of nausea and vomiting in different groups in the second and third trimesters was compared. In the second half of pregnancy, women with complaints of nausea and vomiting were present in all study groups, but they were more common in pregnant women with helminthiasis than in women in the control group. Conclusions. The data obtained on the more frequent manifestation of early toxicosis in pregnant women with helminthiasis and its demonstrated resistance throughout pregnancy prove that helminth infestations negatively affect the course of pregnancy. Key words: helminth-protozoal invasion, placental insufficiency, pregnancy.

Treatment of trophic ulcers of lower extremities is one of the most important problems of surgery. The aim of the study is to determine the features of the microbial landscape of trophic ulcers in various methods of local treatment. The results of studies on the microflora of trophic ulcers of lower extremities in 245 patients of the main and control groups were analyzed. In 96 patients with trophic ulcers (the main group), Miliacil and magnetolaser therapy were used locally in the treatment of trophic ulcers. For the treatment of 60 patients of the first control group with trophic ulcers, Miliacil and laser radiation were applied topically. In the second control group (59 patients), only Miliacil was used. In the third control group (30 patients), 1% dioxidine solution was used topically for the first 7–10 days, and then the treatment was followed by applying the sea buckthorn oil. The microbiological studies of the trophic ulcer contents demonstrated that Miliacil in combination with laser radiation and especially in combination with magnetic laser therapy had a more pronounced antimicrobial effect than only miliacil and even more so than the 1% dioxidine solution and sea buckthorn oil. It was found that in 161 (65.7%) patients the pathogens were inoculated in the form of a monoculture and in 84 (34.3%) - in the form of microbial associations. According to the composition of strains, among monocultures, 67 (41.6%) patients had Staphylococcus aureus, 39 (24.2%) - Proteus, 24 (14.9%) - E. coli, 20 (12.4%) - Pseudomonas aeruginosa and 11 (6.9%) -Streptococcus. The Staphylococcal associations were predominant, they were found in 68 (80.9%) patients. 336 strains of microorganisms were isolated and 296 (88%) of them were resistant to three or more antibiotics. At the end of treatment, in 87 (90.6%) patients of the main group, there was not observed any microflora in the ulcer inoculations. At the end of treatment, the ulcer microflora was not observed in 51 (85%) patients in the first control group, in 36 (61%) patients in the second control group, and in seven (23.3%) patients in the third control group. Thus, as result of studies conducted the specific features of the microbial landscape of trophic ulcers with different methods of topical treatment have been established.

Introduction. So far, surgical soft tissue infection accounts for more than half of all cases seeking specialized medical attendance, and its treatment is sometimes rather difficult. The purpose of the work is to study the results of carboxy-lymphotropic therapy while treating patients with surgical soft tissue infection of the lower extremities. Materials and Methods. The study enrolled 57 patients with manifestations of surgical soft tissue infection of the lower extremities. Criteria for enrollment: patients aged 18 to 75, lack of decompensation for concomitant somatic diseases, and lack of systemic inflammatory response. Withdrawal criteria: patients with diabetes mellitus, cancer, decompensation for concomitant somatic diseases, immunodeficiency states (HIV infection, primary immunodeficiency), injecting drug use, pregnancy and lactation. All patients were divided into two groups: the main group and the control group. The main group included 29 patients who underwent carboxy-lymphotropic therapy. Patients of the control group (n=28) were treated according to the standard protocol. Patients of both groups were examined identically. The examination included the study of the wound fluid pH, bacteriological examination of the wound fluid with antibiotic sensitivity test, cytological screening and the study of the microcirculation in the affected area with a laser analyzer «LAKK – M». Results. Carboxy-lymphotropic therapy as the main treatment method allowed to reduce the duration of patients’ treatment and to accelerate the phase change in the wound process. It was proven both experimentally and clinically. Conclusion. Carboxy-lymphotropic therapy significantly improves treatment outcomes in patients with surgical soft tissue infection of the lower extremities. For patients with microcirculation disorders in the affected area, the described method should be mandatory. Keywords: surgical infection, soft tissues, carboxytherapy, lymphotropic therapy. До настоящего времени хирургические инфекции мягких тканей остаются той областью хирургии, на которую приходится более половины случаев обращения за специализированной медицинской помощью, а ее лечение представляет порой существенные трудности. Цель работы – изучить результаты применения карбокси-лимфотропной терапии при лечении пациентов с хирургической инфекцией мягких тканей нижних конечностей. Материалы и методы. Обследованы 57 пациентов с проявлениями хирургической инфекции мягких тканей нижних конечностей. Критерии включения в исследование: возраст пациентов от 18 до 75 лет, отсутствие декомпенсации по сопутствующим соматическим заболеваниям, отсутствие системной воспалительной реакции. Критерии исключения: наличие у пациентов сахарного диабета, онкологических заболеваний, декомпенсация по сопутствующим соматическим заболеваниям, иммунодефицитные состояния (ВИЧ-инфекция, первичный иммунодефицит), инъекционная наркомания, период беременности и лактации. Все пациенты были разделены на две группы – основную и контрольную. В основную вошли 29 пациентов, лечение которых осуществлялось с применением карбокси-лимфотропной терапии. Лечение 28 пациентов контрольной группы проводилось по стандартной схеме. Подход к обследованию пациентов обеих групп был одинаковым и включал в себя исследование рН раневого отделяемого, бактериологическое исследование раневого отделяемого с определением чувствительности выделенных микроорганизмов к антибиотикам, цитологическое исследование и исследование микроциркуляции зоны поражения с помощью лазерного анализатора «ЛАКК-М». Результаты. Применение карбокси-лимфотропной терапии в качестве основного метода лечения позволило сократить время пребывания пациентов на лечении, ускорить смену фаз раневого процесса, что было доказано с помощью ряда лабораторных методов, а также клинически. Выводы. Карбокси-лимфотропная терапия достоверно улучшает результаты лечения пациентов с хирургической инфекцией мягких тканей нижних конечностей. Для категории больных с нарушением микроциркуляции в зоне поражения данный способ должен являться методом выбора. Ключевые слова: хирургическая инфекция, мягкие ткани, карбокситерапия, лимфотропная терапия.

                                  The issue of preserving the reproductive health of the nation in Ukraine is very acute. The psycho-emotional state of a woman is of particular importance for the prolongation of pregnancy and the normal course of labor. Violation of adaptive mechanisms which are aimed at restructuring the functional systems of the body during pregnancy and on the eve of childbirth, as well as the state of chronic stress contribute to the increase in the of obstetric and perinatal complications frequency and have an adverse effect on the course of pregnancy. The aim of the reaserch was to study the dynamics of psycho-emotional state features in pregnant women after assisted reproductive technologies (ART) application in order to improve the tactics of antenatal surveillance. To achieve this goal, 299 pregnant women were comprehensively examined in the dynamics of prospective observation, which were distributed as follows – the main group included 249 women whose pregnancy occurred as a result of the ART application. The control group consisted of 50 pregnant women with spontaneous pregnancy and its physiological course, which were registered for pregnancy at 6-8 weeks. The women of main group whose pregnancy occurred as a result of ART application were divided into three groups, depending on the factor that caused infertility. The first group included 94 women with tubal-peritoneal factor of infertility, the second group was formed by 87 women with endocrine factor of infertility, the third group included 68 women whose infertility was caused by the male factor. Pregnant women of the study groups by age, marital and social status, place of residence were representative, which allowed further to judge the differences caused by etiological factors of infertility. In order to determine the psycho-emotional state of pregnant women in the study groups in the screening mode, a clinical interview was conducted by filling out questionnaires that contained the constituent questions of the STAI tests in the modification of Yu. L. Khanin and the "Pregnant Attitude Test" by the method of I. V. Dobryakov. The obtained test results indicate that the average score of reactive anxiety in pregnant women of the main group exceeded the same indicator of the control group and was: 49 - pregnant women with tubal-peritoneal type of infertility, 56 - pregnant women with endocrine type of infertility, 44 - pregnant women with male factor of infertility, 24 - control group. According to the results of testing, a significant difference was revealed in the indicators of personal anxiety. The values of indicators of personal anxiety were: 51 - pregnant women with tubal-peritoneal type of infertility, 54 - pregnant women with endocrine type of infertility, 31  -pregnant women with male factor of infertility, 31 - control group. Low level of personal anxiety was observed in 26 (27,6%) pregnant women of I group, 29 (33,3%) pregnant women of II group, which is significantly less in comparison with the indicator of pregnant women of the control group – 33 (66,0%) and III group - 33 (48,5%) (p < 0,05). Moderate type of personal anxiety was observed in 46 (48.9%) pregnant women of group and 40 (45.9%) pregnant women of II group compared to the indicator of the control group – 11 (22, 0%) (p < 0,05). Moderate type of personal anxiety was determined in 25 (36,7%) cases in pregnant women of III group and did not differ significantly from the indicators of I, II and control groups (p > 0,05). A high level of personal anxiety was observed in 22 (23,5%) pregnant women of group I, 18 (20,8%) pregnant women of group II, which is significantly higher in comparison with the indicator of pregnant women of the control group – 6 (12,0%) (p < 0,05). Thus, the study of the psycho-emotional state of pregnant women after the application of ART deviations in the level of personal and reactive anxiety and pathological types of gestational dominant, which are inherent in pregnant women of the main group. Taking into account the above, we consider it appropriate to involve a psychologist to work with the examined pregnant women in order to correct the identified abnormalities.

Objectives. To estimate efficiency, safety and traumatizing impact of endoscopic discectomy in comparison with traditional microsurgical discectomy. Material and methods. A total of 330 patients underwent Destandau endoscopic discectomy and 964 – open microsurgical discectomy. The operative times, terms of patient postoperative bed and hospital stays, postoperative dynamics of neurologic deficiency, surgical complications and frequency of herniation recurrences were estimated in both groups. Pain intensity was assessed with the 10-score Visual Analog Scale (VAS), and functional activity – with the Oswestry Disability Index (ODI). Results of surgical treatment were estimated in 8–10 days, 6 and 12 months after operation. Results. VAS and ODI data have not revealed essential distinctions in pain regression dynamics after endoscopic and open surgeries. Surgical complications after endoscopic intervention were not more often, than after microsurgical discectomy. Damage of dura mater occurred in 2.4 % of cases, and increase in neurologic deficiency (hypoesthesia) – in 0.6 %. Herniation recurrences have evolved in 3.0 % of cases after endoscopic discectomy and in 4.7 % – after open microsurgical one. Conclusion. Destandau endoscopic surgery is a low invasive method of effective treatment for lumbar disc herniations, which by its technical opportunities and results is competitive with classical open microsurgical discectomy.

Objective: Lumbar disc herniation leads the numbness and pain in the waist and lower limbs. Intervertebral foramen endoscopy is a minimally invasive procedure for the treatment of disc herniation. Adequate preoperative evaluation is conducive to this percutaneous skin surgery. The purpose of this study is to improve the efficacy of intervertebral foramen endoscopy in the treatment of lumbar disc herniation by preoperative computer three-dimensional reconstruction combined with pain management. Method: Fifty patients with lumbar disc herniation who met the indications of intervertebral foramen endoscopy were randomly divided into experimental group and control group. The control group was operated according to experience based on the common axial image. The experimental group was punctured according for three-dimensional visualization model of lumbar spine. Preoperative simulated puncture catheterization and perioperative pain management was applied. The catheterization time, operation time under endoscopy, fluoroscopy times during operation, the Visual Analogue Scale (VAS) and Japanese Orthopaedic Association (JOA) scores before and 1 d, 1 m and 3 m after operation were compared between two groups. Result: The three-dimensional visualization model of lumbar spine was reconstructed based on thin-layer data. According to the results of software measurement, the skin puncture point was located and the puncture angle was obtained. Compared with the control group, the catheterization time, operation time under endoscopy, fluoroscopy times during operation in experimental group were significantly reduced. There was no statistical difference in VAS and JOA scores between two groups before operation. Compared with control group, the VAS scores in experimental group at 1 d, and 1 m after operation were decreased statistically, while the JOA scores were increased statistically. Conclusion: Three-dimensional visualization model of lumbar spine and virtual operation planning can directly judge the feasibility of intervertebral foramen endoscopy in the treatment of lumbar disc herniation, improve the efficiency of operation, and further improve postoperative efficacy with pain management.
