Sex education is aimed at equipping individuals with sex-related information, motivation, and behavioral skills that will enable them to avoid sex-related problems and to achieve sexual well-being. Safer sex promotion and condom promotion and distribution programmes have grown significantly since the beginning of the AIDS epidemic. Condom use among young people is especially important because the young are often at greatest risk of HIV infection and have the least access to condoms. In many countries, where the Internet is part of the media landscape, not-for-profit agencies, governments and commercial condom companies alike have started utilising the Internet to promote safer sex and condom use. Most young people have regular access to the internet, and there is some expectation that the Internet is helping to fill the sexual health information gap. The development of an Internet-based, theoretically-driven, innovative approach to sex education weds the special strengths of the Internet as a rich, interactive, individualized pedagogical tool in order to provide effective sex education to large numbers of individuals in a very cost-effective fashion. The proposed approach exploits the characteristics of anonymity, availability, affordability, acceptability, and aloneness of using the Internet. Within this approach, learners are first individually assessed in terms of information, motivation, and behavioral skills deficits that are relevant to the individual's sexual problems and sexual well-being.

Bacteria which cause enterocolitis belong to the genera Salmonella, Shigella, Vibrio, to the thermophilic campylobacters, species of Yesrsinia enterocolitica (Y. enterocolitica) and Clostridium difficile (C. difficile), and to the group of diarrhoeagenic Escherichia coli. The aim of this paper was to determine the frequency of isolation of these microorganisms as well as their resistance to antibiotics. Stool samples of the patients with acute diarrhea were investigated in one-year period. Bacteria were isolated and identified using standard microbiological procedures. Sensitivity testing of Salmonella, Shigella and Yersinia was preformed against the panel of 12 antibiotics, while Campylobactera jejuni/coli against the panel of 7 antibiotics. Among enteric pathogens, Salmonella was the predominant bacterium, with Salmonella Enteritidis (S. Enteritidis) on the first position. S. Enteritidis was resistant to one ore more antimicrobial drugs in 35.6%. Resistance to streptomycin was the most frequently reported - it occured in 21.8% of strains. Resistance to one or more antibiotics in Y. enterocolitica O3 was detected in 87.5% of strains. This bacterium expressed resistance against ampicillin in 87.5% as well. All Shigella spp. isolates were resistant against three or more drugs. Resistance to fluoroquinolones occured in 60% of campylobacter strains. In the examined samples, the predominant bacterium was Salmonella. In S. Enteritidis strains, a notable resistance occurred against streptomycine. Y. enterocolitica O3 expressed relatively high level of resistance, mostly against ampicillin. Multiple resistance occurred in the genus Shigella. In Campylobacter strains, resistance to fluoroquinolones (nalidixic acid and ciprofloxacine) was the most frequent.

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.

Teleradiology has made using the Internet explorer possible to access to images and patient findings, to browse, view and write radiological reports on any computer in any location, with all the appropriate rights (security and confidentiality). Diagnosis, consultation and education of students, doctors and paramedical staff, scientific research, administration, management, planning and improvement of public health got in teleradiology new and powerful tools. In this paper, the authors try to give the right answer to the following questions: what is teleradiology, why teleradiology, the benefits of teleradiology, teleradiolgy success, teleradiology failure, radiology workflow, teleradiology scenarios, mobile radiology etc. The authors conclude that today's teleradiology creates the future radiology.

The association between micronutrients and gastric cancer is still unclear. The aim of this study is to determine the relationship between dietary intake of micronutrients and risk for gastric cancer. We used data from hospital-based case control study conducted at Clinical Centre Nis (Serbia) from 2005 and 2006. Patients (n=102) with first histologically confirmed gastric cancer and matched non-cancer patients (controls, n=204) were interviewed using structured questionnaire and FFQ (Food frequency questionnaire). Multivariate logistic regression analysis showed a significant positive association between gastric cancer and dietary intake of sodium (OR=6.22; 95%CI 1.99-7.86), but a significant negative association between potassium (OR 0.01; 95%CI 0.00-0.08), iron (OR 0.05; 95%CI 0.01-0.56), vitamin C (OR 0.05; 95%CI 0.01-0.38), vitamin E (OR 0.04; 95%CI 0.01-0.29) and niacin (OR 0.07; 95%CI 0.00-0.38) dietary intake. Intake of phosphorus, calcium, magnesium, zinc, retinol, β carotene, tiamin, vitamin B6, and folic acid was not significantly related to gastric cancer risk. In conclusion, we found that a dietary pattern of high consumption of antioxidants (vitamin C, vitamin E, niacin), iron and potassium and low consumption of foods that are sources of sodium, decreased risk for gastric cancer. Our results require confirmation in future studies. © 2011 Versita Warsaw and Springer-Verlag Berlin Heidelberg.
