Background. The variety of the clinical features of vascular tumors in the maxillofacial area limits the choice of method and is able to make difficulties in the treatment. The combined method of treatment proposed by the authors (vascular sclerotherapy with concurrent propranolol intake) demonstrates high efficacy, lack of invasiveness, shortening the rehabilitation period and less side effects. Objective. The aim of the study was to increase the effectiveness of conservative treatment of vascular tumors of the maxillofacial area in young children by combining the method of sclerotherapy and taking propronolol. Methods. In a cohort study, the results of treatment of 80 children aged 2 months to 2 years with vascular tumors of the maxillofacial region (ICD-10: D18.0) were evaluated. A comparison was made of the results in 2 groups of children who were treated with different methods: combined (n =40; main group; sclerotherapy and taking propranolol) and propranolol monotherapy (n =40; comparison group). Analysis of the data obtained in the main group and the comparison group led to the development of the criteria for evaluating the treatment results: good (regression of vascular tumors and the absence of a cosmetic defect), satisfactory (reduction of vascular tumors by 2/3 or more with maintaining cosmetic defect) and unsatisfactory (gross cosmetic defect) in terms of changes in the volume of tumor, the diameter of the supply vessels and the values of the linear velocity of blood flow according to ultrasound data. Results. Subjects treated by the combined treatment had a significant regression of vascular tumors in the maxillofacial area compared with the comparison group: reduction of the tumor volume, diameter of the supply vessels and linear blood flow velocity according ultrasound data reached zero after 6 months from the start of combined treatment — 6 months earlier than in the comparison group (p <0.001). Conclusion. According to the results of the study, the advantage of the author’s method over the traditional method was demonstrated, which resulted in a reduction in the duration of treatment, a decrease in the risk as well as in a degree of complications.

Summary. The aim of the study was to improve the results of treatment of patients with diabetic foot syndrome by applying a complex method of VAC-associated therapy. After 5 days of this treatment we enhanced the local blood flow of wounds from 27-31 to 52-54 mm Hg. (p<0.01), while in the comparison group the blood flow was 29-34 mm Hg, granulation tissue in the wound developed on average 4.93±0.64 days, which was significantly faster than in the control – 9,42±0.81 (p<0,05). Contamination of the wound of the main group before treatment was 8,4±0.14 Lg CFU/g of tissue, for 5 days – 2,8±0.21 Lg CFU/g of tissue, and the regenerative-inflammatory type of cytograms dominated. For 10 days the pathological microflora in the wound was absent, regional epithelialization appeared, the cytogram was of the regenerative type. In the comparison group, contamination before treatment was 8,1±0,17 Lg CFU/g (p<0.05), on the 5th and 10th day the indices were significantly higher than main group– 6,2±0.18 Lg CFU/g (p<0,01) and 3,8±0.19 Lg CFU/g (p<0,01), respectively and the cytograms were still of inflammatory type. The proposed comprehensive method of VAC-therapy provides an effective antibacterial, anti-inflammatory effect, promotes better regeneration and significantly improves the wound healing.

Purpose: to study the effectiveness of seydana (black cumin) oil in combined treatment of herpetic endothelial keratitis. Material and methods. The study included 68 patients (68 eyes) with herpetic endothelial keratitis, developed after cataract surgery. 35 men and 33 women aged 39 to 73 (58.3 ± 8.9) years were divided into two equal groups. The main group (34 patients, 34 eyes) received conventional treatment supplemented with black cumin oil, while the comparison group of 34 patients (34 eyes) received conventional treatment alone.Results. Cornea infiltration in the main group resorbed sooner than in the comparison group (18.43 ± 0.3 days and 23.2 ± 0.5 days respectively; p < 0.05). The treatment lasted shorter in the main group compared with the comparison group (22.1 ± 0.1 days vs. 25.2 ± 0.3 days; p < 0.05). Complete epithelialization was averagely noted on the 19th to the 21st day of treatment (respectively, 19.6 ± 0.9 and of 21.12 ± 0.6; p > 0.05). Visual acuity improved to achieve, respectively, 0.51 ± 0.24 and 0.44 ± 0.17 (p > 0.05).Conclusion. The patients who received seydana oil in addition to conventional treatment showed a significantly higher therapeutic effect in some parameters (resorption time of corneal infiltration and duration of treatment) than the comparison group.

Relevance. The article is devoted to the problem of diagnosis and treatment of acute biliary pancreatitis, which remains one of the most common surgical diseases of the abdominal cavity and accounts for 33.2% of the total number of patients with acute pancreatitis. Objective of the work is to improve the diagnosis and results of surgical treatment of patients with acute pancreatitis of biliary etiology. Materials and methods. The results of treatment of 264 patients with acute pancreatitis of biliary etiology are analyzed. Operative treatment was applied in 92 (34,8 %) patients: endoscopic operations were performed in 44 patients (16,7 %). Thus, in 10 (3,8 %) patients, endoscopic papilloprotectomy was performed with the auditory of the duct system and the extraction of concrements. In other cases, organo-preserving intervention was performed without disturbing the morphofunctional integrity of the sphincter apparatus of the duct system: the cannulation in 6 (2,3%) patients, mechanical (balloon) in 5 (1,9 %) cases, pharmacological (myogenic antispasmodic) dilatation of distal duct and a large duodenal papilla in 11 (4,2 %) patients. In residual choledocholithiasis, a technique of papillotomy under the control of choledochoscopy was proposed – 12 (4,54 %) patients. A comparative analysis of the effectiveness of the treatment of patients who used the "open" (comparative group) and noninvasive endoscopic interventions in the early disease (the main group) was performed. Results. So in the main group the length of stay in the hospital was 12±3,2 days, respectively, in the comparison group – 26±4,3 days. In 42 (95,4 %) patients who had undergone endoscopic surgery, a positive clinical effect, a rapid regress of the symptoms of acute pancreatitis was achieved. In two (4,5 %) patients in the main group, the course was complicated by the development of the abscess of the stuffing box, and puncture under ultrasound control was performed. In patients of the comparison group complications arose in 5 (41,6 %) patients, it is noteworthy that all of them had undergone operative interventions, which were limited only to the rehabilitation and drainage of the abdominal cavity, a stuffing box bag. The mortality rate among unopposed was 1,2 % (2 patients), and among the operated – 11,9 % (11 patients). Among prooperated patients who died, 81,8 % (9 people) were elderly patients. Conclusions. The use of minimally invasive endoscopic interventions in the early phase of the disease reduces the length of stay of patients in the hospital from 26±4,3 days (comparison group) to 12 3,2 days (main group) and the number of complications occurring by 37,1 % (P <0, 05). Application of the proposed method of papillotomy under the control of choledochoscopy makes it possible to reduce the risk of perforation of the wall of the duodenum with the development of peritonitis or retroperitoneal phlegmon by 1,2 % (P <0,05).

Anti Inflammatory

The high prevalence of inflammatory processes in the periodontitis of children, the ineffective effectiveness of preventive and curative measures can contribute to the development of generalized periodontitis, therefore it remains urgent to develop pathogenetic effects in the treatment of chronic catarrhal gingivitis.The aim of the study – a comparative assessment of the traditional treatment of chronic catarrhal gingivitis in children aged 6–7 years with therapy using an anti-inflammatory gel with neovitin.Materials and Methods. 61 children aged 6–7 years, suffering from chronic catarrhal gingivitis, were taken under clinical supervision and divided into groups: the main (30 children) and the comparative (31 children). All children underwent conventional therapy in accordance with the protocols for the provision of medical care – basic therapy. In the main group, for a month, pathogenetic agents were used: an anti-inflammatory gel with neovitin, hygiene products were recommended. In the comparative group, 3 % hydrogen peroxide solution was used for local therapy, for rinsing of the mouth (during the first week of treatment) – Rotokan, a therapeutic and prophylactic toothpaste.Examination and control examinations were carried out with the hygienic state of the mouth determined by the hygienic index of Yu. A. Fedorov and V. V. Volodkina, prevalence and intensity of the inflammatory process in the gums with the help of the Schiller-Pisarev test and the PMA index, oral fluid index (lysozyme content, formation of oxydradicals, urease activity, degree of dysbiosis, pH and viscosity).Results and Discussion. After the treatment, elimination of gum inflammation in patients of the main group was accompanied by a decrease in the PMA index by 3.8 times; formation of oxyradicals decreased in children of the main group by 6.35 %; in the comparative group – by 6.15 %. Urease activity decreased in children of the main group by 16.37 % (p<0.05), the viscosity of the oral fluid of children decreased in 2.65 times in the main group and in 2.13 times in the comparative group (p<0.05). The lysozyme content increased in children of the main group by 15.61 % (p<0.05) in the comparison group – by 9.63% (p<0.05). The treatment after 0.5 years caused an increase in the lysozyme content in the oral fluid of the children of the main group to the level of the control group. The degree of dysbiosis decreased in the main group, in the comparison group tended to increase.Conclusions. The use of the proposed therapy with gel with neovitin contributed to the best results of treatment: reducing the degree of inflammation of the gums, the number of visits to the doctor, improving the indices of nonspecific protection in the oral fluid of 6-7 years-old children and, to a greater extent, six months after the treatment.

Objective: to study the effect of nabumetone in oncogynecologic patients in the postoperative period. Materials and methods. There were examined 98 patients of 40-78 years old, who were divided into two groups: the main group - 58 patients, of which 37 - patients with endometrial cancer I-III and 21 - with ovarian cancer of II-IV stage (FIGO); The comparison group included 40 patients (17 and 23 patients respectively). All patients underwent surgical treatment. In the postoperative period, were used NSAIDs - nabumeton. Before the operation and on the 10th day of the postoperative period, the following parameters were studied: a clinical blood test, TNF-a, ceruloplasmin, diene conjugates (DC), malonic dialdehyde (MDA), antioxidant activity (AOA). The content of TNF-a, in the blood serum was determined by radioimmunological, and DC, MDA, AOA by biochemical method. Results. Established: the content of the leukocyte formula before the start of treatment in the compared groups did not reveal any significant differences. After surgical intervention, both groups showed an increase in the absolute values of all leukocyte fractions. The level of ceruloplasmin in the patients of the comparison group increased significantly in the postoperative period, and in the main group the parameters of ceruloplasmin did not differ significantly. The level of TNF-a in the pre- and postoperative period in the compared groups did not differ. On the 10th day of the postoperative period, it significantly increased in the comparison group, and when nabumetone was used during the postoperative period, the level of TNF-a did not increase. The initial indicators characterizing the processes of LPO and AOA in both groups did not differ significantly. Assessing the dynamics of indicators before and after the operation, it was noted that in patients in the blood, the level of DC in both the baseline and in the comparison group increased. The use of nabumethon led to a slight increase in DC. The maintenance MDA in the postoperative period has increased in both groups, however it is unreliable in comparison with parameters before surgical intervention. In the comparison group, after the treatment, the antioxidant defense was reliably reduced. In the main group, the use of nabumetone contributed to a smaller decrease in AOA. The use of nabumeton allowed abandoning of narcotic analgesics in earlier periods of the postoperative period. Conclusion. Use of nabumeton in the postoperative period allows to reduce the pain syndrome, the number of inflammatory complications; contributes to the normalization of LPO processes, inhibits the inhibition of the antioxidant system, which contributes to the reduction of endogenous intoxication and improves the results of treatment of oncogynecologic patients. Key words: nabumeton, oncogynecologic patients, anti-inflammatory action, tumor necrosis factor, ceruloplasmin, diene conjugates, malanialdehyde, antioxidant activity.

Materials and methods. A retrospective analysis of the treatment results of 369 patients with ECC who were admitted to the clinic for elective surgery in the period from 2009 to 2019 was carried out. There were 264 men 71.5 %) and 105 women 28.5 %). The mean age was 26.9 7.2 years. The patients were divided into 2 groups: 190 patients of the main group underwent surgery using a fiber-optic laser under ultrasound guidance, 179 patients of the comparison group underwent traditional radical excision of ECC with application of primary sutures or various types of plastic. Results. The severity of pain syndrome after surgery in patients of the main group was 1.7 0.6 points, in the comparison group 3.5 1.3 points by a five-point visual analogue scale VAS) for pain. The duration of inpatient treatment in the main group was 1.8 0.4 days, in the comparison group 11.5 1.7 days. Moreover, in 197 76.1 %) patients of the main group, the operation was performed on an outpatient basis. The restoration of working capacity in the main group occurred after 5.2 1.2 days, and in the comparison group after 17.4 2.8. After traditional operations, the relapse of the disease was noted in 11.7 %, and after laser treatment, slightly more than 12.1 %. Satisfaction with the results of treatment in the main group was noted in 95.1 %, and in the comparison group in 90 % of patients. Conclusions. The obtained results of treatment allow us to recommend the technique of interstitial laser obliteration of the coccygeal cyst under ultrasound navigation developed in the clinic for widespread use in practical work of surgeons.

Background. In destructive forms of pulmonary tuberculosis, especially in the presence of drug resistance of mycobacteria, one of the ways to increase the effectiveness of therapy is the use of collapse therapeutic techniques in various modifications. Purpose of the study: to develop and substantiate an algorithm for complex treatment of destructive forms of pulmonary tuberculosis, using artificial pneumothorax (AP). Material and methods: A cohort of 84 people with destructive pulmonary tuberculosis was formed. It was divided into two groups: 42 patients in the main group (chemotherapy (ChT) + AP) and 42 in the comparison group (ChT). Results: an algorithm for the treatment of patients with destructive forms of pulmonary tuberculosis was formulated. Within a period of up to 6 months, abacillation was achieved in 61.9% of cases in the main group (MG), and in 18.9% (p <0.05) in the comparison group (CG). By the 10th month of treatment, the closure of decay cavities was achieved in 78.7% of cases in the MG and in 42.8% (p <0.05) in the CG. By 12 months the closure of decay cavities was observed in 92.1 and 52.4% of cases respectively (p <0.05). Conclusions: The use of the algorithm for the complex treatment of destructive forms of pulmonary tuberculosis makes it possible to achieve abacillation at an earlier time (up to 6 months - in 61.9%). It also allows to increase the frequency of cavity closure by 39.6% as well as achieve an increase in clinical cure (according to long-term results of treatment) by 23.8% and a decrease in the amplification of drug resistance and mortality by 14.3% and 11.9% correspondingly.
