Quality of life is vague and difficult to define, since individual goals, in addition to economic, cultural, religious and educational factors, also have a dominant influence. This study is aimed to determine the differences in the responses received on the quality of life of deaf and hard-of-hearing children and to show which of the two social protections, family or boarding school, provides better conditions for the assessment of the quality of life of these children. The methods used in data processing included descriptive statistics and statistical analysis (Cronbach á, t-test and Pearson's correlation coefficient). All statistical analyses were performed in the statistical program SSPS 19. The sample consisted of 61 students in special schools for deaf children who were examined using a paediatric questionnaire about quality of life (Pediatric Quality of Life Inventory TM PedsQL, version 4.0). The results: With children who were housed in dormitories of special schools for deaf children, during their education we obtained less pronounced results ranging from 0,70 on the sub-scale of psycho-social health to 0,81 on the social scale. Conclusion: The obtained results indicate that children with hearing impairment who are housed in the dormitories of schools for the deaf during their education have a favourable opinion of the quality of their lives, irrespective of the fact that they live in a dormitory compared to children who live with their families.

We propose an approach for the qualitative investigation of polynomial systems of ODEs based on algorithms of computational commutative algebra. It can be applied to study various models of chemical reactions derived using the mass action law. Using it we find all families of systems with invariant planes different from x = 0, y = 0 and z = 0 in the May-Leonard asymmetric model, which is a threedimensional Lotka-Volterra system depending on six parameters. Then we prove existence of periodic solutions for some of these families.

Background/Aim. Flapless implant surgery has become very important issue during recent years, mostly thanks to computerization of dentistry and software planning of dental implants placements. The aim of this study was to compare flap and flapless surgical techniques for implant placement through radiographic and radiofrequency analyses. Methods. The experiment was made in five domestic pigs. Nine weeks following domestic pigs teeth extraction, implants were placed, on the right side using surgical technique flap, and flapless on the left side. Digital dental Xrays were applied to determine primary dental implant stability quality (ISQ). At certain intervals, not later than three months, the experimental animals were sacrificed, and just before it, control X-rays were applied to measure dental implants stability. Results. Radiographic analysis showed that peri-implant bone resorption in the first 4 weeks following placement implants with flap and flapless surgical techniques was negligible. After the 3 months, mean value of peri-implant bone resorption of the implants placed using flap tehnique was 1.86 mm, and of those placed using flapless tehnique was 1.13 mm. In relation to the primary dental implant stability in the first and second week there was an expected decrease in ISQ values, but it was less expressed in the dental implants placed using the flapless technique. In the third week the ISQ values were increased in the dental implants placed by using both techniques, but the increase in flapless implant placement was higher (7.4 ISQ) than in flap implant placement (1.5 ISQ). The upward trend continued in a 4- week period, and after 3 months the dental implant stability values in the implants placed using flap technique were higher than the primary stability for 7.1 ISQ, and in the implants placed using flapless technique were higher comparing to the primary stability for 10.1 ISQ units. Conclusion. Based on the results of radiographic and resonance frequency analyses it can be concluded that the flapless technique in surgical implants placemat, leads to better results.

The relationship between the postmortem interval and the potassium concentration in the vitreous humor has been described by different authors. A limitation of most previous studies might be that all of the vitreous humor has been extracted in 1 sample from different subjects and that the sample was therefore inhomogeneous. In 32 traumatic deaths with known postmortem intervals, small quantities of vitreous humor have been sampled repetitively in 3-hour interval. The bodies were stored at 20°C. The average concentrations of potassium in relation to the postmortem interval were 6.11 to 14.46 mmol/L. An equation that allows accurate prediction of the postmortem interval was established: postmortem interval (h) = 2.749 × [K] - 11.978. Copyright © 2012 Lippincott Williams & Wilkins.

Vitreous humour (VH) is a useful medium for postmortem analysis. During the supravital period, anaerobic glycolysis that occurs results in the increased lactate concentration (L) in cytosol. We analysed the concentration of lactic acid in 567 samples of VH from 63 autopsy cases by a repetitive withdrawal of VH from the same corpse, while the outside temperature remained constant. The samples were taken from the same eye in Intervals of three hours for the period of 24 hours. The subjects were divided into two groups: group 1 included individuals who died during winter and were kept for analysis at 4 °C, while group 2 consisted of those who died during spring and autumn (continental climate) and were stored at 20°C Only the cases of a sudden traumatic death of previously healthy Individuals were included in the study. Statistically significant correlation of L against postmortem interval (PMI) was observed in the group 1 experiment (r = 0.675; P < 0.01), but the effect of hypothermia made the estimation of PMI practically impossible. A much stronger correlation of L against PMI was observed in group 2 (r = 0.866, P < 0.01); a functional relationship between PMI and L were demonstrated using the formula PMI = 1.696 x L - 10.562, which enabled more accurate prediction of the PMI.

We present a case of a 22-year-old male, who was found inside the cage of Himalayan black bears in the Belgrade Zoo. The victim attended the Belgrade Beer festival the previous night, drinking a lot of beer and acting aggressively. A medico-legal autopsy was performed at the Institute of Forensic Medicine in Belgrade. Autopsy findings showed numerous excoriations all over the body surrounded by bruises, as well as spindle-shaped, oval, and partly irregular wounds of variable size, large defects of skin and subcutaneous soft tissue, fractures of the thyroid and cricoid cartilage, and fracture of ribs. Postmortem toxicological analysis revealed the presence of ethanol in vitreous humor and urine and 11-nor Δ9 tetrahydrocannabinolic acid found in the urine. We discussed similar cases from the available literature in different regions of the world. In conclusion, we pointed out that the presented case does not follow the general pattern of Himalayan bear attacks. © 2011 American Academy of Forensic Sciences.

There are many factors that affect smoking behavior.The aim of our study was to identify the most important risk factors related to smoking in the sample population of students at the University of Belgrade with a special emphasize on the family role.The cross-sectional study was conducted in a population of 2,000 students of the Belgrade University. Four faculties (Medicine, Geography, Economics, and Electrical Engineering) from which the students participating in this research were chosen by the method of random choice, conducted in the period April-June 2010.Independent risk factors for smoking in students, assessed by multivariate logistic regression analysis, included: repeating a year (odds ratio (OR) = 1.67, p < .001), the number of hours spent in the rooms where others smoke (OR = 2.86, p < .001), brother smoker (OR = 1.88, p < .001), sister smoker (OR = 2.33, p < .001), knowledge about the association between smoking and lung cancer (OR = 0.31, p < .001), and depression (OR = 1.02, p = .013).Bearing in mind the influence of siblings, prevention, and intervention efforts should be focused more on family members than on the broader social environment. The results also indicate the need to develop a conscience on a healthy life style and to educate people to enhance and improve their health control.

Cerebrovascular insult (CVI) is a known and important risk factor for the development of diabetic ketoacidosis (DKA); still, it seems that the prevalence of DKA among the patients suffering CVI and its influence on stroke outcome might be underestimated. Diabetic ketoacidosis itself has been reported to be a risk factor for the occurrence of stroke in children and youth. A cerebral hypoperfusion in untreated DKA may lead to cerebral injury, arterial ischemic stroke, cerebral venous thrombosis, and hemorrhagic stroke. All these were noted following DKA episodes in children. At least some of these mechanisms may be operative in adults and complicate the course and outcome of CVI. There is a considerable overlap of symptoms, signs, and laboratory findings in the two conditions, making their interpretation difficult, particularly in the elderly and less communicative patients. Serum pH and bicarbonate, blood gases, and anion gap levels should be routinely measured in all type 1 and type 2 diabetics, regardless of symptomatology, for the early detection of existing or pending ketoacidosis. The capacity for rehydration in patients with stroke is limited, and the treatment of the cerebrovascular disease requires intensive use of osmotic and loop diuretics. Fluid repletion may be difficult, and the precise management algorithms are required. Intravenous insulin is the backbone of treatment, although its effect may be diminished due to delayed fluid replenishment. Therefore, the clinical course of diabetic ketoacidosis in patients with CVI may be prolonged and complicated.

Breast cancer is the third most common illness in the world and the most frequent malignant disease with women. Cytotoxic therapy is connected to significant psychiatric adverse effects, and the appearance of depressive symptoms is the most common. The main goal is determining the degree of depression with breast cancer patients in the oncology ward of the University Clinical Hospital in Niš and its connection to their marital status, age, level of education, economic status and the number of therapy cycles. This research is a prospective study. The statistical data analysis included measures of descriptive and analytical statistics. The presence of depressive symptoms of different intensity was showed in 76.00% of the interviewees in group I, and the second included 77.4%. The frequency distributions show that 27.084% interviewees from the first group showed signs of depressive symptoms, while the second included 25%. The intensity of these symptoms categorizes them into the group of moderate to significantly expressed depressive states, so they require therapeutic treatment. Depression is significantly more often recorded with cancer patients receiving cytotoxic therapy; mild depression is the most common, followed by moderate and severe depression. © 2016 Elsevier Ireland Ltd.
