[Phytoprophylaxis of complications after extracorporeal lithotrips].

AIM: To evaluate the efficiency of the drug phytolysin (capsules) in the prevention of complications after extracorporeal lithotripsy. MATERIALS AND METHODS: A total of 15 patients diagnosed with urolithiasis and chronic pyelonephritis in the latent phase were treated. The predominant localization of radiopaque stones no larger than 20 mm in size was the collecting system. The piezoelectric lithotripsy (1-2 sessions) was performed, followed by the administration of the herbal drug Phytolysin in the dosage form of a capsule. The follow-up was carried out after 14- and 30-days using laboratory, ultrasound and x-ray methods. RESULTS: In the postoperative period, there were no cases of the pyelonephritis, which may result from a short-term disturbance of the upper urinary tract urodynamics due to the passage of stone fragments. The antibacterial, antispasmodic, diuretic and anti-inflammatory effects of Phytolysin ensured positive changes in laboratory and bacteriological tests, contributed to the prevention of postoperative complications after extracorporeal lithotripsy (renal colic, pyelonephritis), and contributed to maintaining renal blood flow within normal limits and significantly reduced the time to stone-free status. CONCLUSIONS: Our results justify the feasibility of using phytolysin in capsules in patients with urolithiasis after extracorporeal lithotripsy. The dosage form in capsules eliminates the undesirable effects associated with the specific smell and taste, that patients noted when using phytolysin in the form of a paste.

Variation of the rate of pesticides decomposition used together in the process of agricultural production.

The use of tank mixtures of pesticides makes it possible to increase the efficiency of chemical treatment. The aim of the study was to establish the relationship between the joint use of pesticides and the rate of decomposition of active substances. The study was carried out on the crops of spring wheat, spring barley, peas, spring rapeseed, seed potato. Chemical treatments were carried out with insecticides and fungicides - the insecticide (imidacloprid and λ-cyhalothrin), suspension concentrate; the fungicide (propiconazole), emulsifiable concentrate; the insecticide (imidacloprid), soluble concentrate; the fungicide (copper sulfate tribasic), suspension concentrate. Determination of residual amounts of active substances of pesticides was carried out using methods of gas-liquid chromatography and high-performance liquid chromatography. The acceleration of decomposition of the active substance - imidacloprid on pea crops and spring rapeseed was caused by the combined use of the insecticide (imidacloprid) and the fungicide (propiconazole). The use of the fungicide (copper sulfate tribasic) in a tank mixture with the insecticide (imidacloprid and λ-cyhalothrin) on potatoes caused a slowdown in the decomposition of the active substances imidacloprid and λ-cyhalothrin. Also, there was a change in the level of intake by plant of active substances in the first three hours after spraying, when using tank mixtures, in comparison with the separate use of compounds. The data obtained on the change in the rate of decomposition of active substances of pesticides, when they are used together in mixtures, indicate the need to continue research in this area. In this regard, it is important to study the dynamics of the decomposition of individual active substances of pesticides in plant tissues when they are used in tank mixtures, it is also necessary to conduct research using compounds most commonly used in agricultural production.

Application of soil herbicides in gardening to improve fruit production.

The study considered the use of soil herbicides: Begin Turbo, KS; Dual Gold, KE; Euro-Lighting, VRK; Command, KE; Pivot, VK; Proponite, KE; Zenkor Ultra, KS and partially soil action: Demetra, KE, and Dialen Super, KS. We conducted a comparative assessment of the biological effectiveness of the studied herbicides against the main species of weeds present in the experimental plots, annual and perennial dicotyledonous, annual cereal weeds. The effect of soil herbicide treatments on the physiological state of plants of apple, pear, walnut, and black currant was studied. The effect of the use of the studied drugs on the yield of protected crops for three years was evaluated. The tests proved the applicability of soil herbicides in nursery, production gardens, as well as on seedlings with a closed root system. The tested products, despite the principle of their action - penetration into weeds through the soil, did not harm the protected crops, no negative effect on the growth of trees and shrubs was recorded. The study revealed no evidence that drugs had a negative impact on fruit and berry crop productivity. There are suggestions for improving the efficacy of using soil herbicides when planting fruit and berry crops.

The effect of non-oncology drugs on clinical and genomic risk in early luminal breast cancer.

BACKGROUND: An effect of non-oncology medications on cancer outcome has been proposed. In this study, we aimed to systematically examine the impact of commonly prescribed non-oncology drugs on clinical risk and on the genomic risk [based on the Oncotype DX recurrence score (RS)] in early breast cancer (BC). EXPERIMENTAL DESIGN: We collected data on clinical risk (stage and grade), genomic risk (Oncotype DX RS), and on non-oncology medications administered to 1423 patients with estrogen receptor-positive human epidermal growth factor receptor 2-negative BC during the month of their surgery. The influence of various medications on clinical and genomic risks was evaluated by statistical analysis. RESULTS: Out of the multiple drugs we examined, levothyroxine was significantly associated with a high Oncotype DX RS (mean 24.78; P < 0.0001) and metformin with a low Oncotype DX RS (mean 14.87; P < 0.01) compared with patients not receiving other non-oncology drugs (mean 18.7). By contrast, there were no differences in the clinical risk between patients receiving metformin, levothyroxine, or no other non-oncology drugs. Notably, there was no association between the consumption of levothyroxine and metformin and proliferation marker (Ki67) levels, but both drugs were significantly associated with progesterone-related features, suggesting that they influence genomic risk through estrogen-dependent signaling. CONCLUSIONS: The results of this study indicate a significant impact of metformin and levothyroxine on clinical decisions in luminal BC, with potential impact on the clinical course of these patients.

[Improvement of oncologic results of transurethral resection in the treatment of non-muscle-invasive bladder cancer].

AIM: To evaluate the efficiency of additional methods of intraoperative control during transurethral resection (TUR) for the treatment of non-muscle invasive bladder cancer. MATERIAL AND METHODS: A total of 138 patients (92 men and 46 women) with non-muscle-invasive bladder cancer (Ta-T1N0M0) were treated in the urological clinic of Kazan State Medical University. The median age was 59 years. In 28 patients TUR was performed as monotherapy, in 28 patients TUR with photodynamic therapy (PDD) was done and other 26 patients undergone TUR under dynamic transurethral ultrasound control. In 29 patients, TUR was combined with a single intravesical instillation of a chemotherapy drug, and in 27 patients, TUR was combined with long-term intravesical chemotherapy. The frequency and type of relapses was evaluated depending on the treatment method during five-year follow-up period. Analysis of postoperative complications and their severity was performed according to the Clavien-Dindo classification. Statistical analysis was performed using the Statistica 7.0 and Microsoft Excel 2003 software package. Survival was assessed using the Kaplan-Meier method. Differences in survival between groups were determined using a log-rang test. RESULTS: The total 5-years recurrence rate in the group 1 was 60.71% (n=17). There were 6 recurrences in the resection area (21.43%) and 8 recurrences outside the resection area (28.57%). The progression rate was 10.71% (n=3). In the group 2, the overall recurrence rate was 25% (n=7), including 2 (7.14%) and 4 (14.29%) recurrences in and outside resection area, respectively. The progression rate was 3.57% (n=1). In the group 3, where TUR was performed in combination with transurethral ultrasound, 7 recurrences were diagnosed over a five-year period (26.92%), including 1 recurrence in the resection area (3.84%) and 6 recurrences in other parts of bladder (23.07%). There was no progression of bladder cancer. In the group of patients who received a single intravenous chemotherapy after TUR, there were no significant differences with the group of patients where TUR was performed as monotherapy. The total number of recurrences was 55.16% (n=16). There were 4 recurrences in the resection area (13.79%) and 9 recurrences in other parts of bladder (31.03%), as well as 3 case of disease progression (10.34%). At the same time, in the group of patients where prolonged course of adjuvant intravesical chemotherapy was performed, a significant decrease in the recurrences rate in the resection area (7.4%; n=2) and progression (3.7%, n=1) was found. The number of recurrences outside the resection area was comparable with the group 1 (22.22%; n=6). CONCLUSIONS: According to our data, we recommend to perform TUR in combination with PDD and transurethral ultrasound in order to improve the oncological results. Long-term intravesical chemotherapy is an effective alternative in case of inability to use additional intraoperative control and it should be included in the treatment scheme of patients with a high risk of recurrence.

[Use of fixed individual micro-implant supported orthodontic appliance in children with bilateral cleft lip and palate]. / Primenenie nes"emnykh individual'nykh ortodonticheskikh apparatov s oporoi na mikroimplantatakh u detei s dvustoronnei rasshchelinoi guby i neba.

Congenital malformations of the maxillofacial region are significant, not completely decisive, medical and social problems. Recent literature data indicate a trend towards improvement. PURPOSE OF THE STUDY: Improving the effectiveness of treatment of children with bilateral orthodontic and surgical training. MATERIAL AND METHODS: Under the supervision were 80 children with cleft lip and palate, with an age of up to 3 years. Of these 56 patients, 28 patients are the 2nd group prepared for surgery according to the developed technique. RESULTS: Preoperative orthodontic preparation of 28 children with bilateral cleft and an indicator that 22 (78.6%) patients should not have fully achieved results between the interhuman and fragmentary alveolar process of the upper jaw. In the second group of patients, 27 (96.4%) patients showed a normal ratio of the intermaxillary bone and lateral fragments. CONCLUSION: The use of the developed orthodontic design with active elements and mini implants in 96.4% of cases requires the presence of pre-spiral orthodontic preparation, normalization of the position of the intercellular bone and shape, followed by primary chelorinoplastics and in relation to additional uranoplastics, as well as the periodic stages of rehabilitation of patients with bilateral cleft lip and achieved thereby a stable aesthetic and functional result.

[INTRAOPERATIVE CONTROL OF THE EFFECTIVENESS OF TRANSURETHRAL RESECTION OF NON-MUSCLE-INVASIVE BLADDER CANCER].

This paper presents results of 82 patients treated for non-muscle-invasive bladder cancer. 28 patients underwent transurethral resection of bladder cancer (TURB) as a monotherapy, 28 - TURB with photodynamic control, 26 - TURB with dynamic transurethral sonography. Analysis of the 5-year recurrence rate, pattern and timing of recurrence depending on the modality of intraoperative control of TURB effectiveness was performed. The overall recurrence rate in the first group was 60.71%, of them local recurrence in the resection area occurred in 21.43% of cases, outside of the region of resection - in 28.57% of cases, and progression - in 10.71%. In the second group the overall recurrence rate was 25%, recurrence in the resection area was diagnosed in 7.14% of patients, outside of the region of resection - in 14.29% and progression - in 3.57%. In the third group of patients over a 5-year period local recurrence in the resection area was identified in 3.84% of cases, outside of the region of resection - in 23.07% of cases and no cases of disease progression were observed. The results showed that TURB without additional intraoperative imaging of surgery effectiveness was not a radical treatment for non-muscle-invasive bladder cancer. Photodynamic control increases the surgery effectiveness by preventing recurrences outside the resection region. It allows identifying microscopic modified urothelium clones, but does not affect the rate of disease progression. Intraoperative transurethral ultrasound guidance increases TURB effectiveness by preventing both relapse in the area of resection and disease progression.

[Therapy of rapid ejaculation using dietary supplement "NeyroDoz": results of a multicenter non-randomized clinical study].

The main aim of the study was to determine the effectiveness of a multicomponent dietary supplement NeyroDoz in patients with rapid ejaculation. We examined 50 patients with rapid ejaculation (premature ejaculation), who were recruited in 9 clinical centers in different regions of Russia. These patients received NeyroDoz, 2 capsules twice a day for one month, followed by a control observation for 1 month. In study group of patients, symptomatic improvement was achieved in 45 (90%) of 50 patients at 4-week observation target date. In assessing the impact of NeyroDoz on different groups of symptoms, it was found that it significantly increases the average time of sexual intercourse by 2 times, increases the orgasm brightness, reduces the severity of psychosomatic component and has a positive effect on all components of the copulative cycle. In assessing the afterimpression, this effect was maintained throughout the period of follow-up.

[The use of ProstaDoz in patients with chronic prostatitis. Results ofa multicenter nonrandomized clinical study].

The main purpose of the study was to determine the effectiveness of a multicomponent dietary supplement ProstaDoz in patients with chronic prostatitis. The study included 50 men with clinical symptoms of a chronic prostatitis, which were observed in 9 clinical centers in different regions of Russia. All patients have received 2 capsules of ProstaDoz twice a day for 1 month, followed by dynamic observation for 4 weeks. Symptomatic improvement was achieved in 46 (92%) patients. Evaluation of effects of ProstaDoz on various groups of symptoms has revealed that it reduces pain, promotes urination normalization and improvement of quality of life. These effects were maintained during all follow-up period.

[Study of cross-activity of Streptococcus pneumoniae antigen preparations].

AIM: Study cross-activity of S. pneumoniae antigen preparations. MATERIALS AND METHODS: Antigen preparations were obtained by ultrasound disintegration (from bacteria in R-form), extraction with water (from serotype 3 bacteria), cetavlon and trichloroacetic acid (from serotype 6A bacteria). Chemical composition and immunochemic properties of preparations were studied by contemporary methods as well as in experiments with direct and cross-protection of mice from infection. RESULTS: 3 of 4 preparations (except ultrasound disintegrate) had approximately 30% of protein. In immunodiffusion reaction they interacted with hyper immune rabbit sera obtained against 12 various pneumococcus serotypes--1, 3, 4, 6A, 6B, 9V, 9N, 14, 18C, 19A, 19F and 23F. In animal experiments 30 - 70% of mice were protected from subsequent infection with knowingly high dose of homologous and 3 heterologous pneumococcus strains. In immunoblotting the highest number of components serologically active with heterologous sera was formed by cetavlon extract (12 - 23). Addition of capsule polysaccharides to the preparation increased its cross-protective activity. CONCLUSION: By data set and the highest yield, water extract is reasonable for isolation of cross-reactive proteins of pneumococcus. Development of another method of extraction from cultural fluid is necessary for obtaining extracellular protein antigens. Generation of vaccines containing cross-reactive proteins of pneumococcus and capsule polysaccharides is a promising direction.

Susac syndrome: clinical characteristics and treatment in 29 new cases.

BACKGROUND AND PURPOSE: There are few clinical studies on the attempted treatments and outcomes in patients with Susac syndrome (SS) (retinocochleocerebral vasculopathy). METHODS: A retrospective review was performed of all patients presenting with SS at the Mayo Clinic in Rochester, Minnesota, USA (1 January 1998-1 October 2011). RESULTS: There were 29 cases of SS (24 women, mean age at presentation, 35 years; range, 19-65; full triad of brain, eye, and ear involvement, n = 16; mean follow-up time, 29 months). Thirty CSF analyses were performed in 27 cases (mean protein 130 mg/dl, range 35-268; mean cell count 14, range 1-86). MRI of the brain showed corpus callosal involvement (79%), T2-weighted hyperintensities (93%), and gadolinium enhancement (50%). Average lowest modified Rankin Scale score was 2.5 (median 2, range 0-5). Most patients (93%) received immunosuppressive treatment, with a mean time to treatment of 2 months following symptomatic onset. Treatments included intravenous methylprednisolone or dexamethasone (n = 23), oral corticosteroids (n = 24), plasma exchange (PLEX) (n = 9), intravenous immunoglobulin (IVIg) (n = 15), cyclophosphamide (n = 6), mycophenolate mofetil (n = 5), azathioprine (n = 2), and rituximab (n = 1). Most patients also received an antiplatelet agent (n = 21). Improvement or stabilization was noted in eight of 11 cases treated with IVIg in the acute period (three experienced at least partial deterioration) and eight of nine cases of PLEX treatment (one lost to follow up). CONCLUSIONS: Susac syndrome may be severe, disabling, and protracted in some patients. PLEX may be an adjunct or alternative therapy for patients who do not experience symptomatic improvement following steroid treatment.

[Monoclonal antibodies to rubella virus glycoprotein E1].

AIM: To obtain monoclonal antibodies (MCAs) to glycoprotein E1 of rubella virus, to assess their immunochemical characteristics and ability to use fluorescent MCA for rapid identification of rubella virus. MATERIALS AND METHODS: Rubella virus strain C-74 (Moscow), vaccine strains "Orlov" (Saint-Petersburg), Wistar RA 27/3 (USA) as well as strain Judith (Germany) were used. Viral antigens were obtained using diploid cells L-68 and cell lines VNK-21-F and Vero E6. MCAs were produced by conventional method and their isotype was determined: Immunoblotting, immunoenzume assay (IEA), hemagglutination inhibition assay (HIA) and immunofluorescence assay (IFA) were performed. RESULTS: Five monoclonal antibodies--Kh-252.1, Kh-347.2, Kh-183.3, Kh-214.4, Kh-187.5--to antigens of rubella virus strain C-74 were obtained. Isotypes of these antibodies were determined and their reactivity with native and denaturated antigens of other strains ("Orlov", Wistar RA 27/3, Judith) was characterized. IEA showed that all MCAs interacted with rubella virus glycoprotein E1 at high titers ranging from 1/1600 to 1/200,000. Immunoblotting demonstrated that 4 MCAs (Kh-252.1, Kh-347.2, Kh-183.3, Kh-214.4) had aforementioned feature. MCAs inhibited hemagglutinating activity of Judith strain in titer from 1/16 to 1/1024 in HIA. FITC conjugate of MCA Kh-347.2 (most sensitive variant) allowed to detect rubella virus in infected Vero E6 cells after 24 hours since infection, whereas FITC conjugates of 3 MCAs (Kh-183.3, Kh-214.4, Kh-187.5)--after 72 hours since infection. CONCLUSION: Use of FITC conjugates of MCAs is a perspective tool for identification of rubella virus glycoprotein E1 in infected cell cultures and nasopharyngeal swabs.

[Reasons for grounding flying personnel with urolithiasis].

Analysis of reasons for grounding flying personnel with urolithiasis showed that most of the professional pilots with the record of service of 19.7 +/- 1.3 yrs. had not been given treatment at the young age (mean age - 35.1 +/- 1.7 yrs.). After a course of treatment, more than 80% of the pilots got rid of renal stones and were cleared for flight duties. Therefore, timely treatment of flying personnel with urolithiasis minimizes medical discharge of pilots considering the high costs of air crew training.

[Efficacy of vitaprost forte in the treatment of prostatic adenoma].

Thirty patients with a documented diagnosis of prostatic adenoma were treated with vitaprost forte (100 mg rectal suppositoria) for 60 days. Treatment efficacy was assessed after therapy and for two months with a 30-day interval. It is shown that the drug can be used as monotherapy. Its efficacy was proved by improved urodynamics of the lower urinary tract, reduction of prostatic size. A therapeutic effect after the drug discontinuation points to a complex organotropic action of the drug. Side effects were not registered. Vitaprost forte is recommended for treatment of patients suffering from prostatic adenoma with mild and moderate symptoms.

[Prophylactic medicine--a foreground direction of medical support of the air staff of aviation of the Armed Forces of Russian Federation].

The first prophylaxis of chronic not-infection diseases obtains more and more value. Level of these diseases among air staff is rather high and has a tendency of increasing. It's bounded up with defects in the system of the first medical unit, insufficient conducting of ecological and sanitarium-hygiene screening and taking steps on decreasing of the influence of noxious agent on the human organism, improvement of working conditions of air specialists, decreasing of the value of psychoemotional stress and other factors. An important factor during the conducting the first and the second prophylaxis is an early detection of changes in health by the air staff and technical-engineer staff, diagnostics of diseases on early stages, when they conduct without any symptoms, forehanded rehabilitation and treatment.

[Improvement of extracorporeal shockwave cholelithotripsy in the comprehensive treatment of cholelithiasis].

The method of shockwave distant lithotripsy (DL) has been used since 1985. However, many facets of this problem have not been solved yet, because large fragments of the stone remain after its destruction, and focused shock waves (FSW) damage the gallbladder (GB). The aim of this study was to determine possibilities of effective distant destruction of gall stones, to reveal negative consequences of the effects of FSW on the gallbladder (GB) and the surrounding tissues, as well as development and perfection of DL technique. The established parameters of FSW were used to develop the new Lithotriptor Compact. By now, 53 patients with cholelithiasis aged 18 to 55 have been treated by DC. The procedure was performed without general anesthesia. A thousand to 3500 shockwave impulses were applied to each stone. All patients had received litholytic therapy and treatment directed towards metabolic normalization, the functional state of the GB, and prevention of recurrent stone formation, prior to DL. In total, 116 DL sessions (2.2 sessions per a patient) were performed. A positive effect as a result of the complex treatment of cholelithiasis using DL method was achieved in 47 (88.7%) of the patients. There were no complications. In 3 patients (5.7%) recurrence of gallstones was found two years after DL sessions. Correctly selected parameters of FSW and DL technology allow for effective destruction of GB stones, while conservative therapy favors their passage through the biliary tract and fast litholysis of remaining stone fragments.
