Aim — the study purpose was to analyze the efficacy of intra-arterial administration of verapamil (IAV) in the treatment of angiospasm in SAH patients and to determine optimal parameters of the procedure. A number of studies demonstrated the efficacy of intra-arterial administration of vasodilators, in particular verapamil, in the treatment of angiospasm after aneurysmal SAH, which served the basis for inclusion of this method in the recommended protocol for treatment of SAH patients [1―7]. Material and methods. We analyzed the efficacy of IAV in 35 patients in the acute period of SAH, with 77.2% of the patients having a Hunt-Hess score of III―V. The inclusion criteria were as follows: IAV within two weeks after SAH; excluded aneurysm; verapamil dose per administration of at least 15 mg; follow-up for at least three months. Efficacy endpoints were as follows: changes in spasm according to angiography and transcranial dopplerography (TCDG); development of ischemic lesions; clinical outcome according to the modified Rankin scale. Results. A total of 76 IAV procedures were performed. The verapamil dose per procedure was 36.7±9.7 mg, on average; the number of procedures varied from 1 to 5. One arterial territory was treated in 12 cases, two arterial territories were treated in 48 cases, and three arterial territories were treated in 15 cases. Typical adverse reactions included decreased blood pressure, a reduced heart rate, and elevated ICP. In all cases, TCDG revealed signs of reduced angiospasm ― a 20―40% decrease in the LBFV in the M1 MCA. Four (11.4%) patients died; of these, only one died due to angiospasm progression. On examination at 3 months or more after discharge, favorable outcomes were observed in 74.3% of cases. Conclusion. IAV is associated with a low risk of significant complications. IAV should be performed under control of systemic hemodynamics and ICP. The indications for IAV include signs of moderate worsening or severe angiospasm according to TCDG and/or angiography. The IAV procedure may be performed every day. Further clarification of the IAV procedure and evaluation of clinical outcomes under prospective study conditions are required.

The radiation has an antitumor effect and causes radiation reactions and damage to surrounding tissues within the framework of combined antitumor treatment of patients with cancer of maxillofacial region. It also has an irreversible effect on the production of saliva by large and small salivary glands, and this must be taken into account when planning radiation therapy for this group of patients.

The relevance of the investigation is due to the need to optimize the system for the primary prevention of drug addiction and use because of its insufficient efficiency in the Russian Federation. This problem is manifested in the low awareness of the population, primarily young people, about the negative consequences of the use of narcotic drugs and psychotropic substances and about the high associated risk of their involvement in the use of narcotics, including new types of psychotropic substances (synthetic narcotics). In this connection, the aim of our investigation was to develop a method for determining the potential efficiency of measures for the primary prevention of drug addiction and use, by applying mathematical modeling. The Kermak - McKendrick epidemic model of the susceptible infected removed (SIR) - like type was used as a basis to build a drug use spread model that represented as transition of groups of individuals from one state to another in relation to drug use. This gave rise to a simulation model estimating the magnitude of a drug use reduction in the risk group in relation to the initial one if varying effective preventive measures were implemented. The drug abuse scenario in case of effective measures was analyzed. Enhancing the effectiveness of measures for primary prevention of drug addiction was shown to lead to a stronger rather than linear decline in the size of a group at risk for drug and in the number of drug users. This model may be used to prepare programs, strategies for the primary prevention of drug addiction to evaluate their potential effectiveness.

Injuries to the pectoral girdle can be an underlying cause of CS pain, including cervicalgia. The aim of this study was to evaluate the condition of the cervical spine in patients with cervicalgia developed after a pectoral girdle injury using radiographic and physical examinations. The study included 400 patients complaining of cervicalgia. Pain intensity was evaluated on the visual analog scale (VAS); the impact of the condition on patients' lives was assessed using the Neck Disability Index (Russian language). During physical examinations, the general health of the spine was evaluated and abnormalities in the cervical spine were noted. All participants underwent a radiographic scan of the cervical spine in the lateral and anterior-posterior projections; 49.5% of patients underwent postural digital radiography to evaluate their CS sagittal profile. All patients received an MRI scan. Based on the results, we identified certain functional changes in the cervical spine which possibly caused cervicalgia. Structurally and functionally, the changes were divided into static and dynamic. We conclude that cervical spinal pain is a common problem among patients with previous pectoral girdle injury.

The creation in the middle of the 20th century vaccines against poliomyelitis (PM) - inactivated vaccine (IPV) and live oral vaccine from Sabin strains (OPV) with various properties, advantages and disadvantages, but highly effective, made it possible to implement the idea of elimination of PM. Since 1988, the WHO Global Program of PM eradication has achieved remarkable success: the incidence of PM caused by wild poliovirus (PV) has been reduced by 10 thousand times, the number of endemic countries has been reduced to 3, the circulation of wild PV has been discontinued in 4 regions of the world the wild type 2 of PV has been eradicated, and wild type 3 of PV has not been detected for almost 5 years. Under conditions of a decrease in the incidence of PM caused by wild PV, the known negative properties of trivalent OPV made its further use problematic. These negative properties are: 1) the ability to cause post-vaccination complications and 2) the genetic instability of Sabin strains, especially PV of type 2, and their ability under certain conditions (primarily in conditions of low collective immunity to PV) to quickly restore neurovirulence, transforming into circulating vaccine-derived PV (VDPV), capable of causing incidents and outbreaks of PM. In order to reduce the risk associated primarily with type 2 PV, WHO proposed a global switch to the use of bivalent OPV from types 1 and 3, completed in 2016. In 2019, WHO plans to complete eradication of type 1 and 3 PVs, and in 2022 completely abandon the OPV. The precondition for the safety of such tactics is the maintenance of high collective immunity to PM. There are several threats to the security of this strategy. PVs can "silently" circulate in the human population for a long time without clinical manifestations of PM, which, with inadequate epidemiological surveillance can lead to the return of PM. The reintroduction of both wild PV and Sabin strains can occur from institutions that preserve / work with PV. The source of VDPV can be people with primary immunodeficiencies, which continuously excrete PV. It is necessary to maintain surveillance over the PM, expand additional types of surveillance for the PV, strict containment of all PVs. The only way to maintain collective immunity is immunization with trivalent IPV. The current global shortage of IPV poses a significant threat to the world's epidemiological well-being. The solution to the problem is the development of a new generation of safe and effective vaccines, improving the ways of introducing IPV, developing antiviral drugs.

Sacroiliac joint (SIJ) dysfunction often causes nonspecific low back pain; the efficiency of its treatment is discussed to be exhibited by therapeutic blockades with anesthetics and glucocorticoids (GCs) or by SIJ radiofrequency denervation (RFD). Objective: to investigate the efficiency and safety of therapeutic blockades with anesthetics and GCs, or SIJ RFD in the combination therapy of chronic low back pain due to SIJ injury. Patients and methods. The investigation enrolled 51 patients (36 women and 15 men) aged 32 to 75 years (mean age, 56.4±2.1 years). Group 1 included 32 patients (mean age, 51.75±2.65 years) who used periarticular blockades with local anesthetics and GCs; Group 2 consisted of 19 patients (mean age, 64.1±2.8 years) who underwent SIJ RFD. Results and discussion. These treatments showed high efficiency and safety. Three months after a treatment cycle, there were reductions in the intensity of pain (by an average of 47%; p<0.0001) and in the degree of disability and improvements in the physical and psychological parameters of quality of life. There were no substantial differences in the health status of patients in the two groups treated with blockades with anesthetics and GCs or SIJ RFD. Conclusion. It has been shown that the incorporation of blockades with anesthetics and GCs or SIJ RFD into the treatment of patients with chronic low back pain can improve the results of therapy.

Their efficacy is still being investigated. The use of biofeedback when teaching pelvic floor muscle exercises to patients increases the effectiveness of therapy. Objective: to assess the efficacy of biofeedback-assisted pelvic floor muscle training in patients with urinary incontinence after laparoscopic and robot-assisted radical prostatectomy and to compare the results of teaching. Materials and methods. A total of 64 patients with urinary incontinence after nerve sparing prostatectomy underwent biofeedback-assisted pelvic floor muscle rehabilitation. Radical laparoscopic surgery was performed in 48 (75 %) patients, whereas robot-assisted surgery was performed in 16 (25 %) patients. The patients started their training 2 months postoperatively. We used two-channel electromyography with the Neurotrack ETS system (United Kingdom) to teach the patients isolated pelvic floor muscle contractions. After achieving a minimum activity of abdominal muscles during pelvic floor muscle contractions, the patients started exercises. Results. There was no significant difference in age between patients who underwent laparoscopic and robot-assisted radical prostatectomy (р = 0.79). Fifty-five patients (85.9%) acquired the skill of isolated pelvic floor muscle contractions and could perform training on their own. The remaining 9 patients (14.1 %) required regular support from healthcare professionals at an outpatient unit (1-2 biofeedback-assisted trainings per month). Thus, the type of surgery did not affect the process of training. The type of radical prostatectomy had no impact on the acquisition of the pelvic floor muscle contraction skill. Conclusion. The time for restoration of urinary continence by biofeedback-assisted pelvic floor muscle training did not vary between patients after laparoscopic and robot-assisted radical prostatectomy.

The choice of the reconstruction technique depends on the tumor size and localization, type of the defect, patient’s age, concomitant diseases, and disease prognosis. Surgeons have currently a broad range of material for reconstructive surgery, from free flaps to revascularized flaps. Microsurgical reconstruction has made a revolution in treatment of patients with complex head and neck defects. However, the use of this technique may not be advisable for some patients. The search for new techniques is needed to improve functional and aesthetic results and reduce traumatism without compromising oncologic outcomes. Thirty-six patients underwent surgery with reconstruction using the submental island flap, a new alternative in the reconstruction of various head and neck defects. The graft was taken after making a neck incision for neck lymph node dissection. A few patients develop total and marginal necrosis of the graft. Short- and long-term results showed no worsening of oncologic outcomes in the selected group of patients.

We present the clinical case of the male patient of 38 aged. He was admitted to the clinic with heart failure 3-4 NYHA class. EchoCG revealed symmetric hypertrophy of the left ventricle up to 18 mm without its dilatation, a decrease in ejection fraction up to 42%, restrictive hemodynamics, overload of the right chambers, severe pulmonary hypertension (60 mm Hg). The clinical status included persistent arterial hypertension (180-220 and 120-150 mm Hg), effusion in both pleural cavities and pericardium, ascites, renal failure. During examination (multispiral computed tomography, magnetic resonance imaging, scintigraphy with 131I-MIBG), bladder paraganglioma was diagnosed (normatenafrin 1468 μg/day). The resection of the tumor was performed, according to immunohistochemical research - neuroendocrine carcinoma, G1. After 3 months a partial regression of hypertension and cardiac failure was observed with the preservation of a high level of creatinine. The criteria and differential diagnosis of the hypertensive heart disease and the syndrome of primary myocardial hypertrophy, diagnostics of the urinary bladder paraganglioma, complex mechanisms of myocardial damage within the pheochromocytoma and its prognosis are discussed..

The main aim of the study was to determine ways of improving the results of treating patients with ulcer bleeding of various nature and severity. It was provided by the system study of free radical processes and evaluation of the effectiveness of timely antioxidant therapy. Material and methods. The study included 153 patients aged 18-94 years with acute and chronic gastric and duodenal ulcers complicated by gastroduodenal bleeding. Patients were divided into two groups: group I (experimental group) included 62 patients who received antioxidative therapy with reamberin as a part of the basic therapy; and group II (control group) included 91 patients who received standard therapy. Various parameters of Free Radical Processes (FRP) were studied in dynamics in all patients. Results. We revealed the significance of oxidative stress on the first day of hospitalization in patients with gastrointestinal ulcerous bleeding of various character and severity. It was discovered mostly in severe patients with acute Gastroduodenal Ulcerous Bleeding (GDUB). In case of mild gastrointestinal ulcerous bleeding, oxidative stress disorders affected an oxygen stage of oxidative stress and represented themselves adaptive compensatory mechanisms. As the severity of the disease increased, intensification of an oxidant stress was manifested by a decrease in oxygen activity and an increase in lipid imbalance. Imbalance in free radical processes continued for a long time until discharge of patients from the hospital. The data obtained claimed to be the basis for recommendation to include antioxidant energy-conserving therapy in the complex of therapeutic measures in the earliest possible terms. We found out an efficacy of using succinic acid therapy with reamberin in patients with gastrointestinal bleeding. Positive effect of succinic acid on the markers of oxidative stress was confirmed by improvement in the disease pattern and success of the treatment.

Two methods have been employed to purify specific rabbit polyclonal antibodies against recombinant human alpha-synuclein, produced by subcutaneous immunization with complete Freund's adjuvant. It was shown that purification on CNBr-activated Sepharose with immobilized alpha-synuclein resulted in antibody preparation with rabbit serum histidine-rich glycoprotein as a contaminant. Two-stage antibody purification procedure first on Sepharose with immobilized protein G, and then on alpha-synuclein immobilized column helps to avoid contamination and to obtain homogenous antibody preparation. Antibodies recognize different conformations of alpha-synuclein and can be used in a variety of immunochemical approaches, including immunocytochemistry.

To study the effects of long-term instillation of 0.18% sodium hyaluronate artificial tears VISMED multi on ocular surface in glaucomatous patients with long-term instillation of preserved anti-glaucoma drops. Material and methods. The study included 79 patients (40 female and 39 male; 79 eyes in total) with primary open-angle glaucoma (POAG) divided into 3 groups according to disease stage: mild or early (stage I) glaucoma - 15 patients (15 eyes), moderate (stage II) glaucoma - 30 patients (30 eyes), advanced or severe (stage III) glaucoma - 34 patients (34 eyes). Conjunctival and corneal changes were assessed with Norn's test, Schirmer I test and corneal fluorescein staining test. All patients completed Ocular Surface Disease Index (OSDI) questionnaire. Corneal compensated intraocular pressure (IOPcc) was measured using Ocular Response Analyzer (ORA) (Reichert Optics Inc., USA). In addition to hypotensive therapy, all patients received instillations of 0.18% sodium hyaluronate (VISMED multi) three times every day. After 14 days, all examinations were repeated. Results. The condition of eye surface in patients with moderate and advanced (stage II and III) glaucoma depends on the degree of IOPcc compensation. As glaucoma increases in severity, the pathological changes in the ocular surface progress. Instillations of 0.18% sodium hyaluronate solution lead to significant improvement of the test results in all groups, and in early glaucoma patients it restores all objective indicators to normal values. Conclusion. Treatment with 0.18% sodium hyaluronate solution (VISMED multi) leads to statistically significant (p<0.05) improvement of ocular surface condition in glaucoma patients with long-term instillation of preserved antiglaucoma eye drops.

Objective: to compare the predictive value of RENAL, PADUA, C-index nephrometry score systems according to projection of complexity of operative measure in terms of warm ischaemic time, extent of blood loss and rate of postoperative complications. Materials and methods. Information for the research was collected from 314 patients with localized kidney cancer, who had laparoscopic partial nephrectomy from January 2012 to May 2017. In 210 (66.8 %) cases, in addition to the routine examinations, 3D modelling and operative measure planning were carried out. The average tumor volume of the patients was equal to 62.5 ± 33.5 mm3. All patients before the operation were estimated the complexity of operative measure on the nephrometry score systems: PADUA, RENAL, C-index. The average sum of balls according to scale RENAL - 7.56 ± 1.12, on scale PADUA - 7.98 ± 1.55, on scale C-index - 2.76 ± 1.14. Then in retrospect by the method of logistic regression analysis was determined predictive value of RENAL, PADUA, C-index nephrometry score systems for prediction of warm ischaemic time, duration of operative measure, extent of intraoperative blood loss and possibility of rate of postoperative complications. Results. In 265 (84.4) cases transperitoneal approach was perfomed and in 49 (15.6 %) cases it was retroperitoneal approach. The average time of laparoscopic partial nephrectomy is 140.15 ± 55.8 min, the average time of ischaemic warm is 13.35 ± 7,65 min. The average extent of blood loss during the laparoscopic partial nephrectomy is 291.95 ± 196.5 ml. Intraoperative complications were found in 8 (2.54 %) cases. Postoperative complications were estimated according to the Clavien-Dindo classification of surgical complications and were found in 31 (9.9 %) cases, among them 12 (3.8 %) patients had surgical complications. The index of the RENAL nephrometry scoring system had the highest predictive value in the multivariant analysis for warm ischaemic time, extent of intraoperative blood loss and possibility of development after complications (p = 0.049; 0.028; 0.046). None of indices were significant for multivariant analysis of prognosis the duration of laparoscopic partial nephrectomy. The indices of the RENAL (p = 0.032) and C-index (p = 0.040) nephrometry score systems were significant for univariate analysis of prognosis the duration of the laparoscopic partial nephrectomy. Conclusion. The usage of RENAL, PADUA, C-index nephrometry score systems is useful for the prediction of warm ischaemic time, extent of blood loss, duration of operative measure and possibility of rate of postoperative complications at laparoscopic partial nephrectomy. According to our data the index of RENAL nephrometry scoring system has the highest predictive value. Applications of 3D modelling for counting nephrometry indices in preoperative period makes the process of counting balls easier on all three nephrometry score systems.

The high recurrence rate after conventional transurethral resection (cTUR) for bladder cancer (BC) requires search for more effective methods of surgical treatment. Objective: to evaluate the feasibility, safety, and efficacy of cTUR versus thulium laser en bloc resection of bladder tumors using new fiber laser "Urolaz". Materials and methods. 129 patients, who underwent surgical treatment for BC between 2015-2017 in urological department of I.M. Sechenov First Moscow State Medical University were included in the study. The cTUR were performed for 58 patients, 71 patients underwent thulium laser en bloc resection of bladder tumors. Results. The presence of detrusor muscle in specimen was 58.62 % in cTUR group and 91.55 % in thulium laser en bloc resection group respectively. Obturator nerve reflex, bladder perforation, and bleeding in thulium laser en bloc resection group were absent, therefore immediate instillation of chemotherapy was made in all these cases. Recurrence rate after 12 and 18 months after surgery in the group of en bloc resection was statistically lower compared to the cTUR group. Conclusion. The results, obtained in our study shows that thulium en bloc resection using thulium fiber laser "Urolaz" is feasible, effective and safe procedure for patients with BC. Thulium en bloc resection has a number of advantages over the cTUR: Absence of obturator nerve reflex, high quality of specimen for pathological examination (presence of detrusor muscle in specimen was 91.55 %) and low recurrence rate.

The speech disfluencies in the adolescents differ from those of the adults by frequency of self-corrections and pauses of hesitation. The adolescents rarely turn to repair their narratives but often interrupt the speech flow by pauses while telling a story stimulated by a wordless book. The lack of self-corrections reflects the specific problems with self-control and self-regulation due to immaturity of the executive function. Narrating about a complex multi-propositional event, the adolescents often experienced hesitation that provoked more self-repairs and hesitation pauses compared to the telling the story about a simple event. The description of the relatively simple content was more complicated syntactically than that of the multi-propositional event. Meanwhile, the content complexity significantly influences frequency of the silent hesitation pauses.

Still's disease in children (systemic-onset juvenile idiopathic arthritis, SoJIA) and in adults (adult-onset Still's disease) are considered as non-familial systemic autoinflammatory diseases of unknown etiology driven by similar immunopathogenetic mechanisms. The adult-onset Still's disease pathogenesis is based on genetically determined innate immunity disturbances and molecular basis of immunopathogenesis consists of NLRP3 inflammasome-dependent mechanisms of inflammation characterized by hyperproduction of proinflammatory cytokines interleukin (IL) 1 and IL18. Nonsteroidal anti-inflammatory drugs, glucocorticoids, methotrexate and other disease modifying drugs are considered as «first line» medications for the treatment of adult-onset Still's disease and if they fail biologi-cals are recommended. A review of the literature data concerning anti-IL1 monoclonal antibodies administration in adult-onset Still's disease is presented, indicating good prospects for the use of canakinumab not only in case of resistance to standard therapy, but also as a «first-line» therapy in the onset of the disease.
