Singidunum Journal of Applied Sciences , 2012,
Abstract: Science and religion are two distinct but not two hostile paths: two ever valuable efforts of human spirit! Science and religion would have less intellectual disputes and social conflicts if only both of them would explicate their principles, and then in even dialogue, espy and evaluate possibilities and frontiers of their principles and sorts of enabled questions and answers. Religion might be interesting for science as it opens new and unknown fields of human experience. Frontiers of science and religion are historically changeable, which does not mean that they can escape. Religion is not a sort of less developed science, but an independent way of thinking, beliefs and actions, offering to believer a solution of some problems otherwise unsolvable, even by assistance of science and its methods.

Abstract: The incidence of squamous cell skin center is the second, after basocellular skin cancer. Surgical treatment is the first and most effective therapy for this tumor. The aim of study is to present experiences of Surgical clinic in Nis in treatment of squamous cell skin cancer in head and neck. During 10-year period (1990-2000) there were operated 346 patients with squamous cell skin cancer of head and neck. We performed wide surgical exsicion with clinical free margins of 5-10 mm, and more radical excision and reconstructions for advanced tumors. We registered postoperative complications in 14 (4,04%) patients. Early diagnose and adequate treatments of squamous cell skin cancer are preperiquisite for good postoperative results and low complication rate.

Abstract: The Danube River in the vicinity of the city of Belgrade receives large amounts of untreated or poorly treated communal and industrial waste waters. The aim of this study was to assess elemental accumulation patterns in a number of economically important fish species in this area that belong to different trophic levels. Concentrations of 17 elements (Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Se, Sr and Zn) were assessed in liver, muscle, gills and gonads of silver carp (Hypophthalmichthys molitrix), freshwater bream (Abramis brama), white bream (Blicca bjoerkna), common carp (Cyprinus carpio) and wels catfish (Silurus glanis) from the Danube River in Serbia by the use of ICP-OES. Silver carp specimens were differentiated from the other four species by high concentrations of Al and Fe in the liver. Common carp specimens were differentiated by high concentrations of Zn in gills, muscle and liver. Distribution of elements among different tissues had a consistent pattern among the species. Concentrations of Pb, Cd, As, Zn, Cu and Fe in muscle were at acceptable levels for human consumption, while concentrations of Fe and Zn were above maximum acceptable concentrations in liver and gonads. Le Danube à proximité de la ville de Belgrade re oit de grandes quantités d’eaux usées communales et industrielles non traitées ou mal traitées. Le but de cette étude était d’évaluer les schémas d’accumulation des éléments dans un certain nombre d’espèces de poissons économiquement importants dans cette région, qui appartiennent à différents niveaux trophiques. Les concentrations de 17 éléments (Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Se, Sr et Zn) ont été évaluées dans le foie, le muscle, les branchies et les gonades de la carpe argentée (Hypophthalmichthys molitrix), la brème commune (Abramis brama), la brème bordelière (Blicca bj rkna), la carpe commune (Cyprinus carpio) et silure glane (Silurus glanis) du Danube en Serbie par l’utilisation de l’ICP-OES. Les spécimens de carpes argentées se différencient des quatre autres espèces par des concentrations élevées d’aluminium et de fer dans le foie. Les spécimens de carpes communes sont caractérisés par de fortes concentrations de Zn dans les branchies, les muscles et le foie. La répartition des éléments entre différents tissus a un schéma semblable entre les espèces. Les concentrations de Pb, Cd, As, Zn, Cu et Fe dans les muscles étaient à des niveaux acceptables pour la consommation humaine, tandis que les concentrations de Fe et Zn étaient au-dessus des concentrations maximales acceptables dan

Abstract: Introduction. Investigation of adolescent sexual behavior carried out on a large sample is primarily motivated by health and social problems which can occur when young people practice sex without protection and necessary information. There is no data that the national study on adolescent sexual behavior has been conducted in the Serbian speaking area. Objective. Monitoring and follow-up of trends in adolescent sexual behavior. Methods. The investigation sample comprised 1101 adolescents (472 male and 629 female), aged 13-25 years. As an instrument of polling, the questionnaire 'Sexual Behavior' was used specifically designed for the purpose of this investigation. Results. Eighty-four percent of males and 65% of females reported having sexual experience. The age of the first sexual experience, total number of partners, number of sexual partners in the last year and the last month were investigated, and the number of loved and sexual partner compared. In addition, the length of foreplay, frequency of sexual activity, masturbation, sexual dreams and sexual daydreams and engagement into alternative sexual activities (oral sex, anal sex, group sex, exchange of partners) were estimated, as well as the reasons for their practicing. Sexual desire and its correlation with personality dimensions, the frequency of sexual disorders (erectile and ejaculation problems, anorgasmia), abortion, rape and identification of the rapist, the use of condoms and other methods of contraception were assessed. Conclusion. It could be postulated that biological influence on sexual behavior is powerful and resistant to the influence of time and place, as well as socio-cultural religious influences. A high rate of premarital sexual activity with a number of sexual partners, a relatively low rate of condom use and the fact that 4% of the female adolescents in this sample had an induced abortion suggest that there are gaps in the education provided to adolescents about sexual and reproductive risks within the Serbian speaking territory. An alarming statistic is that 5% of the female adolescents in this sample reported that they had been raped, or forced to participate in non-consensual sex within an ongoing relationship with a regular partner. There is a need for systemic changes within the field of sexual education and protection from sexually risky behavior among young adults.

Abstract: In the course of the first six months of 2004, 852 patients have undergone operations in Ophthalmology Clinic Ni{ for various forms of cataract. Out of the total number of patients operated for cataract, in 164 (19.2%) cases we performed an ultrasound cataract operation - phaco - emulsification. During the operation, all patients received implantation of PMA lenses. The method of phacoemulsification has been performed on Millennium apparatus, manufactured by Baush&Lomb company, while me - thod of extracapsular extraction has been performed after classical limbal incision with opening of 10-12mm. During our work, we analyzed the number of postoperative and operative complications in 164 patients operated by ultrasound method and compared it with the same findings for 165 patients operated by manual extracapsular method with implantation of hard intraocular lenses. We also analyzed the length of hospital stay and postoperative visual acuity for both groups of patients. The results reveal that the number of operative and postoperative complications caused by application of phacoemulsification method has been significantly lower compared to the technique of manual extracapsular extraction. Postoperative recovery is much quicker in patients operated by ultrasound method; local status during the first postoperative day shows a smaller number of pronounced signs of postoperative reactions (redness of the eye, corneal edema, exudation signs). The average length of recovery for patients operated by extracapsular method was 3.5 days, while for patients operated by phacoemulsification it was only one day.

Abstract: Breast carcinoma is the most common female malignancy. Mastectomy and breast reconstruction are indicated to treat the disease and to improve quality of life. The aim of this study was to compare the esthetic results of breast reconstruction with extended latissimus dorsi flap and implant for breast cancer with and without denervation of latissimus dorsi muscle. Our study was a retrospective review of prospectively collected data. Surgery was performed as primary reconstruction in 24 (75%) and secondary reconstruction in 8 patients (25%). All patients were consecutively divided in two equal groups (with 16 patients each) with latissimus dorsi muscle intact or denervated. Their average age was 46.2 years. Primary reconstruction was done for stages I and IIA, and secondary reconstruction one year after the completion of oncologic treatment. Postoperative follow-up was two years.Early complications (hematoma, infection) were not observed and dorsal seroma was observed in four women (12.5%). Partial flap necrosis was found in one case, but complete flap necrosis was not found. In six patients (18.7%), unacceptable scarring at the donor site required correction.Two years after reconstruction the patients assessed the procedure as very good or excellent. Excelent grade was often statisticaly significant in the group with innervated flap. Primary or secondary breast reconstruction should become an integral part of breast cancer treatment. Extended latissimus dorsi flap with implant is a safe and relatively simple reconstruction technique and should be preferred to other similar techniques. We suggest the reconstruction with innervated musle flap for better esthetic results.
QALY - Measure of Cost-Benefit Analysis of Health Interventions

Acta Facultatis Medicae Naissensis , 2011,
Abstract: For the purpose of economic evaluation in the health economics, several analytical techniques that are designed for comparing two or more health interventions in terms of costs and effects are used. Cost-benefit analysis provides the opportunity of comparing values of alternative health interventions that have very different health benefits, which significantly facilitates comparisons. The purpose is to assess the relationship between the cost and utility of health interventions in terms of the patient’s number of years in full health. The most commonly used measure in these analyses is QALY (Quality-adjusted life-year). QALY is a measure of the impact of health interventions and treatment that combines two dimensions of health outcomes: the degree of health improvement and the time period for which the improvement of health is exhibited, including the length of life. Determining the QALY is one of the most effective ways of decision-making about distribution of resources in the health care system. The method is designed to distribute resources in such a way as to be spent where they will bring the maximum possible benefit for the patient. If we have to make decisions how to direct funds from limited budgets, then each and the lowest cost has to correlate to the maximum possible benefit and these methods are the best tool under such conditions.
Measures for Improving the Quality of Health Care

Acta Facultatis Medicae Naissensis , 2012,
Abstract: Quality and safety in the health sector go “hand in hand”, which means that both components are inseparably linked - quality improvement will often affect more security. Good quality services will be successfully implemented in organizations that already have a "quality culture", i.e., where the value system of employees is consistent with their commitment to providing high quality health services. The organization must have a clear strategic commitment to providing quality services at all levels of an organization. Quality and safety are not "an extra element in providing services, but make its ground. As such, the quality and safety must be built into the organization. Patient satisfaction, quality service and efficient management of resources become “holy trinity” of modern health care, strictly oriented towards the patient, aimed at reducing costs while increasing quality. Healthcare system worldwide try to develop new strategies, the implementation of which would lead to the end result -improvement of health care quality.
