It is well known that there is a relationship between the zinc and diabetes, and its antioxidant potential. Based on that, the aim of this paper is to investigate the effects of different doses of zinc (9,2 and 18,4 mg / day) in combination with metformin and glibenclamide, to the total antioxidant status (TAS) and the activity of the enzyme superoxide dismutase (SOD) in experimentally-induced diabetic rabbits. The study was conducted on 24 New Zealand rabbits of both sexes, body weight 2,5 to 3,2 kg. In rabbits, experimental diabetes was induced i.v. injection of alloxan (80 mg / kg body weight). Three weeks after causing diabetes, the animals were divided into two groups: first group was treated oral with metformin, an appropriate dose (120 mg / kg body weight), while the second group of rabbits was treated with a suitable dose of glibenclamide (0,6 mg / kg BW). After the washout period (10 t1/2), the rabbits were treated with metformin and a first dose of zinc (9,2 mg) combination, i.e. glibenclamide and zinc (9,2 mg). After another washout period (10 t1/2) the rabbits were treated with metformin and a second dose of zinc (18,4 mg) combination, i.e. of glibenclamide and zinc (18,4 mg). Blood samples were taken in a specified time interval. The TAS value was significantly increased after administration of metformin, single and in combination with zinc, in doses of 9,2 and 18,4 mg, with respect to the value recorded before their application (p <0.05). Also, it is noted a significantly increased SOD activity after administration of metformin (i.e., glibenclamide), and zinc in combination, in a dose of 18,4 mg (p <0.05). This indicates that zinc and metformin have a significant positive effects on the parameters of antioxidative status, but with glibenclamide this effect did not occur.

Topiramate is a newer drug with a strong antiepileptic potential, but also with adverse effects, especially on cognitive functions. This review deals with the study covering the impact of topiramate on cognition in patients with epilepsy. The most common side effects are included somnolence, psychomotor slowing, difficulty in memory, concentration and attention disorder and problems with speaking. Most studies have shown that a high initial dose, rapid titration and application in polytherapy increase the risk of cognitive impairment after-introduction of topiramate. In addition, depression and early onset of the disease can also contribute to cognitive adverse effects, even at low doses of the drug. Although topiramate indisputably linked to the risk of interference cognitive impairments, some studies suggest their reversibility. This, together with high efficiency antiepileptic obliges researchers to continue searching for the risk factors and mechanisms of cognitive side effects in order to define the profile of patients who would be of maximum benefit of the drug in controlling seizures with absent or acceptable side effects.

Arthritis following dyzentery or urethritis was mentioned before our era and later by many others. In 1818 Benjamin Brodie described 5 patients with typical „ Reiters disease”: urethritis, conjunctivitis, arthritis. Many diagnostic criteria for Reiters disease / reactive arthritis have been proposed for practical purpose the most acceeptable is the folowing one: posturethritic or postenterocolitic arthritis is Reiters disease / reactive arthritis. The findings of Chlamydiy from the synovia or in the synovial fluid of itients with RD suggest that arthritis may be of infective but not of reactive origin.

The presence of regional metastases of laryngeal cancer differs depending on the location of the tumor and has an influence on the overall survival. The aim of this work is to analyze the frequency and characteristics of regional metastases T1 and T2 of laryngeal carcinoma in relation to the primary tumor location, and their effect on the overall survival. A retrospective study, conducted in the period between 2002 and 2012, that analyzed 445 patients who were surgically treated for laryngeal cancer of T1 and T2 category. The first group consisted of 397 patients without regional metastases, while the second group consisted of 48 patients with regional metastases. A three-year survival is followed, as well as the testing of potential predictors of outcomes by methods of regression. Regional metastases were present in 3.1% of patients with glottic carcinoma of T1 and T2 category, while 43.5% of patients with T1 and T2 supraglottis carcinoma had regional metastases. In the group with regional metastases, there is no statistically significant difference in the occurrence of extracapsular extension in relation to the tumor location, p = 0.7027. The three-year survival rate of patients without regional metastasis is 93.95%, while the survival of patients with regional metastases is 68,75%, p = 0.000. The tumor location (95% CI -1.4716 to -0.0497, P = 0.0369), and the presence of regional metastases (95% CI -1.6300 to -0.0253, P = 0.0443), were identified as predictors of outcomes by multifactorial analysis. Regional metastases in T1 and T2 laryngeal cancer are more common in patients with supraglottic carcinoma. The presence of regional metastases significantly reduces the three-year overall survival.

Healthy nutrition in childhood is of major importance for maintenance of health in adults. Early detection of nutritional status impairments in children is directed toward prevention of chronic non-contageous diseases. Obesity in children is reported as the most important public health problem in pediatrics in developed countries. The aim of this study was to established the frequency of overweight and obesity, as well as blood pressure levels in population of 4-years aged children. This study enrolled 125 children aged 4 years. The survey was conducted during their regular systematic exams. Nutritional status was estimated from standard antrhropometric measurements. Data regarding nutritional habits, as well as physical activity were collected from parents, using questionnaire. 67,2% of childred were normaly nourished, 19,2% were overweight, 10,4% were obese, and 3.2% undernourished. Average values of body weight on birth were similar, regardless of nutritional status and gender, as well as actual BMIs o parents. Sedentary activities were the most frequent in overweight children of both gender, which is statisticaly significant when compared to normally nourished (2,61 # 1,36 h vs 1,91 # 0,98 h; p<0,05 for boys; 2,75 # 0,96 h vs 1,89 # 0,80 h; p<0,05 for girls). Significantly higher values of blood pressure were recorded in obese boys compared to normally nourished (systolic BP: 101,25#6,41 mm Hg, vs 96,36#4,86; p<0,05; dyastolic BP: 71,25#6,41 mm Hg, vs 66,14#4,81; p<0,05). Obese girls had significantly higher systolic BP compared to normally nourished: 103,33#5,77 mm Hg, vs 97,03#5,19; p<0,05. Obtained results indicate the relationship between obesity and higher blood pressure even in such young children, which is the major contribution of this study, considering the lack of investigations in similar populations, as well as the previously established fact that increased risk in childhood may predict the development of cardiovasculard diseases in adult life.

This case report describes the application of adhesively cemented restorations made out of related, although not identical types of ceramic materials in the treatment of inborn hypodontia of the lateral incisors, as well as the aesthetic imperfections of certain teeth in the whole smile. Considering the minimally invasive approach, and the preservation of natural tooth fibers, the restorations have shown to be acceptable both aesthetically and functionally, and have proven themselves as a safe and comfortable solution for patients.

Determination of preoperative prostate-specific antigen (PSA) value is primary procedure in diagnosis of different pathological prostate changes (prostate cancer-PC, prostatic intraepithelial neoplasia-PIN and benign prostatic hyperplasia-BPH), followed by digital rectal examination and prostate biopsy as gold standard. Disadvantage of high sensitivity and low specificity of PSA testing in diagnosis of PC is a problem in clinical practice. Aim was to determine the diagnostic performance of PSA in diagnosis of PC, PIN and BPH. The study included 100 patients divided into three groups: 70 with PC, 20 with a PIN and 10 with BPH. Patients with PIN and BPH were control group. Preoperative PSA values were determined by Tandem-R, The patients were divided into subgroups by baseline PSA level as follows: 4-10, 11-20, 21-30, 31-40 and> 40. The definitive histopathological diagnosis was made on routine hematoxylineosin slides. The area under the receiver operating characteristic curve (ROC), sensitivity-SE and specificity-SP of each PSA level were evaluated for PC. Preoperative serum PSA levels in patients with PC (median-35.82 ng/ml, min-6 ng/ml, max-960.40 ng/ml) were significantly higher than with PIN (median-9.15 ng/ml, min-3.16 ng/ml, max-27.61 ng/ml) and BPH (median-8.68 ng/ml, min0.80 ng/ml, max-31.20 ng/ml). The best diagnostic characteristics of the PSA are on limit value 10 ng/ml (AUC=0.781, SE=92.9%; SP=63.3%; p<0,0001). PSA is of great help in diagnosis of advanced and initial form of PC. The chance of PC diagnosis was greater than that for other pathological changes when PSA level was higher than 10 ng/ml.

Acute bleeding of the upper gastrointestinal tract is an urgent condition with high morbidity, and a significant mortality despite advanced diagnostics and therapy. The goal is to investigate the determinants of the severity of duodenal peptic ulcer bleeding. The research included 304 patients hospitalized for acute bleeding from the upper part of gastrointestinal tract in a five year period. They had been treated in the Clinical Hospital Center Bežanijska Kosa in Belgrade. The diagnosis was made via gastroduodenoscopy. Out of the 304 patients, 197 (65%) suffered from bleeding peptic ulcer. 144 (73,1%) patients suffered from bleeding duodenal ulcer, most frequently with bulbar localization 124/86 (12%); 78 (62,9%) with a duodenal bulb back wall lesion. 48 (35,1%) of the bleeding duodenal ulcers were in the Forrest Ib stage, in 68 (47,2%) patients the size of the ulcer lesion was between 1,1-2,0 cm. A statistically positive correlation was determined between the duodenal ulcer lesions and the intensity of the bleeding (p<0,005). With 68/79/86,1% patients treated endoscopically, haemostasis was successful, whereas in 13/19,1%, rebleeding was localized in 11/84,6% in the duodenum bulb bask wall.

Salmonellosis are food-borne toxinfections flowing with the clinical picture of acute enterocolitis, and are caused by non-typhoid salmonella (Salmonella food poisoners). The main objective of the study was to identify the most important epidemiological characteristics of salmonellosis in Serbian areas of Kosovo and Metohija We used the data or reporting of infectious diseases, reports on infectious diseases (seven-day, month, year) of the Public Health Pristina in Kosovska Mitrovica. In our research we used epidemiological Studies of cross-section (cross-sectional) Between 2003-2015.god. Kosovo and Metohija (Serbian middle) registered 250 cases of salmonella. The average incidence in the reporting period was 12.35 / 10,0000. Analysis of age distribution revealed that the most common incidence in people aged 20-29 years, and the rarest people ages 15-19 godina.salmoneloze occur throughout the year showing seasonal variations. The trend in the incidence of salmonellosis is decreasing in the territory of Kosovo and Metohija Based on the results of our study we can conclude that a significant salmonellosis both public health and animal health but also economic problem .Epidemiological situation with regard to salmonella requires intense activity in the field of food safety not only medical services, but also veterinarians and veterinary and sanitary inspection.
