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.

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.

Introduction: Dental caries is the most common oral disease in all age groups. Being more and more frequent in preschool and school-age children, it has become one of the most important problems in oral pathology. The aim of this study was to determine the incidence of dental caries in schoolchildren aged 12 and 15 years in the northern part of Kosovo and Metohija, as well as to inform them about the importance of oral health. Materials and Methods: The study included 626 schoolchildren of both sexes from five schools from the municipalities of Kosovska Mitrovica, Zvečan and Leposavić. Klein-Palmer DMFT system (D-Decayed, M-Missing, F-filled) was used to estimate the prevalence of dental caries the following indices were also used: Person Caries Index, Teeth Caries Index, Average Caries Index and DMFT structure. All the selected children were examined using standard dental diagnostic agents. Tooth surfaces were examined dry under artificial lighting. Results: The average value of DMFT index for children aged 12 and 15 years was 4.2. On average, 92.3% of the examined children had caries. The mean value of caries index was 15.11%.Conclusion: After these new epidemiological studies, it can be concluded that the state of children's oral health, considering the high levels of untreated caries and all other features of DMFT index, is not satisfactory. This situation points to the necessity of applying modern preventive and prophylactic measures to preserve and improve the population oral health.

The panoramic radiography is the most used diagnostic imaging method in planning impacted lower third molar extractions. However, often panoramic radiography does not provide enough information in treatment planning for performing safely surgical extraction of impacted third molars. CBCT (Cone beam computed tomography) provides more precise information in diagnostic analysis especially for planning surgical procedures where complications can be expected due to close relationship between mandibular canal and lower impacted third molars. The aim of this study is comparative analysis of panoramic radiography and CBCT in evaluating the topographic relationship between mandibular canal and impacted third molars. The study included 50 patients with close relationship between mandibular canal and impacted third molars detected using panoramic radiography. After panoramic radiography analysis CBCT was performed in order to diagnose, plan and prevent complications during the surgical tooth extraction. CBCT examination considered comparative analysis with panoramic radiography, marking, volume rendering and assessment of mandibular canal in buccolingual direction. Out of total patients where suprimposition of mandibular canal and impacted third molar on panoramic radiography was detected, in 32 patients mandibular chanal was localised on lingual side. Mandibular canal was positioned at bucal side in 18 of 50 patients. Results of this research indicate that panoramic radiography can be useful in everyday practice for diagnosis, planning and preparing lower third molar extractions, but in cases where close relationship between mandibular canal and lower third molars is detected CBCT is recommended as more precise radiographic imaging method in order to prevent complications.
