[Worldwide, cervical cancer remains the second most frequent malignancy. The estimated number of new cases is 450,000 per year. Approximately 80% of affected women live in developing countries where access to cervical screening programmes is limited. In Europe, more than 12,800 women die each year from this preventable disease. Human papilloma virus (HPV) infection has been proved to be a potential cause of cervical cancer. Secondary screening decreases the morbidity and mortality of the disease, but does not prevent HPV infection. HPV-DNA can be detected in 90-100% of preinvasive and invasive cervical cancer cases. Trials assessing prophylactic anti-HPV vaccination have confirmed that the vaccination is a suitable method for the primary prevention of precancer lesions and cervical cancer.]

[The significance of media literacy in adolescent smoking and drinking]

PIKÓ Bettina, BALÁZS Máté Ádám, PAGE M. Randy

[INTRODUCTION - Media exerts a strong socialization effect on adolescents who are particularly susceptible to different messages in this life period. In the present study, therefore, we focused on adolescents’ media literacy. METHODS - 546 adolescents from Makó (Southern Hungary) were studied, including 288 (52.7%) grade 8 (age 13-15 years) and 258 (47.3%) grade 12 (age 17-19 years) students; 49.5% of the participants were male and 50.5% female. The survey covered sociodemographic variables, lifetime and monthly prevalence of smoking and drinking, attitudes related to substance use and media literacy. For the study of media literacy, we adapted a Medica Literacy Scale containing 31 items. After performing factor analysis, factors of media literacy were analyzed by two-sample t-tests according to sociodemographic variables and behaviour. RESULTS - Our results show that factors of media literacy are well differentiated according to sociodemographic variables and even more according to smoking and drinking behaviour. Girls and younger adolescents (among who substance use is less frequent) are more likely to notice the hidden messages of substance use that are shown in advertisements and movies, and the representation of the interests of the tobacco and alcohol industry in the media. Nonsmokers and nondrinkers are a lot more aware of the manipulation effects of the media. CONCLUSIONS - Our results draw attention to the significance of media literacy in the prevention of adolescent smoking and drinking.]

[Dangers of the use of performance enhancement drugs and food supplements]

PUCSOK József

[The history of humankind is full of stories related to performance enhancement drug abuse. For the purpose of improving explosive power and long-term physical performance central nervous system stimulating drugs and supplements, such as: amphetamine and cocaine have been used. Androgenic anabolic steroids are used for increasing skeletal muscle mass. The abuse of performance enhancer drugs is seriously deteriorating the human health, and have several negative side effects. Number of food-supplements - available in the market, often contain traces of steroids. So called designer steroids are extremely dangerous. In the near future it will be possible to enhance physical performance through genetic interventions.]

[Switching from human basal insulin to once daily insulin detemir in type 2 diabetic patients treated by basal-bolus regimen - Results from the LEONCET2, an observational, prospective, multicenter study]

JEMENDY György

[Insulin analogues have been developed in order to overcome some drawbacks of human insulins. Switching from a human insulin-based basal- bolus regimen to once daily detemir could result in improved metabolism and increased safety of the therapy. We assessed the effects of switching from human NPH-insulin to once daily detemir insulin in patients with type 2 diabetes mellitus treated with a basal-bolus insulin regimen. We evaluated the data of 1,474 patients with diabetes (age: 59.1±9.8 years, body weight 89.6±8.6 kg, BMI 31.6±5.4 kg/m2) in an observational, prospective, 24-week, multicenter study. All patients were treated with a basal-bolus regimen consisting of human NPH as basal insulin and a human or analogue insulin as bolus insulin. After enrollment, patients received once daily detemir insulin instead of NPH-insulin, while treatment with bolus insulin was continued. Patients were examined at weeks 12 and 24. By week 24, the mean HbA1c value, irrespective of BMI-categories, decreased significantly (p<0.0001) from 8.63±1.01% by 0.79±0.63%. Fasting blood glucose level decreased from 8.86±1.78 mmol/l to 7.09±1.31 mmol/l; p<0.0001). The target level of HbA1c (<7.0%) was reached by 194 patients (13.1%). The patients’ body weight decreased significantly by week 12 (-0.69±2.00 kg; p<0.0001) and by week 24 (-1.28±2.80 kg; p<0.0001). The changes were more pronounced in higher than in lower BMI-categories (p for trend <0.0001). The mean daily doses of basal insulin were increased from 0.28 IU/kg to 0.33 IU/kg while those of bolus insulins were not changed. The rate of severe hypoglycaemic events decreased significantly (p=0.048) from 2.95 [daytime 1.02, nocturnal 1.93] to 0.06 [daytime 0.04, nocturnal 0.02] episodes/patient-year. In patients with type 2 diabetes mellitus treated with basal-bolus regimen, switching from human basal insulin to once daily insulin detemir results in a significantly improved metabolism, as well as fewer hypoglycaemic events and decreased body weight. Nevertheless, the low rate of patients reaching the glycaemic target implicates that some factors other than an appropriate basal insulin substitution have a role in achieving an optimal metabolic control.]

[Young men’s knowledge about the human papillomavirus]

BALLA Bettina Claudia, TEREBESSY András, TÓTH Emese, BALÁZS Péter

[Introduction - Nearly the fifth of more than 100 HPV serotypes affect the anogenital region causing genital warts, penile and anal cancer. The incidence of male pathologies is lower than that of females (genital warts, vaginal, vulvar, cervical and anal cancer), however they are equally important in epidemiological terms. Methods - The aim of our questionnaire-based cross-sectional study was to assess the HPV-related knowledge of young men in 19 randomly selected high schools in Budapest. The anonymous questionnaires contained 54 items about socio-demographic and lifestyle factors, HPV-related knowledge and the attitude toward HPV vaccination. Results - We collected 530 completed questionnaires (86.74% response rate). 35.3% of the students knew that HPV was an STD and 3.2% was aware of transmission via skin contact. The majority (52.5%) linked cervical cancer to the viral infection, 7.7% linked HPV to the genital warts of females and 8.3% to the genital warts of males, 9.8% to penile cancer and 4.2% to anal cancer. 44.7% of the young men would have their future children vaccinated, while 24.5% remained uncertain. Conclusions - The young men’s knowledge about HPV was poor and they underestimated the risk of infection. This emphasizes the importance of targeted health education in this population. However, the students were mostly in favour of the HPV vaccination.]

[ORAL CARCINOMA AND ITS PREBLASTOMATOSES: THE ROLE OF PAPILLOMAVIRUS INFECTION AND THE PROSPECTS OF EARLY DIAGNOSIS]

DECSI Gábor, TARNAI Zsófia, ZSEDÉNYI Ádám, BUZÁS Krisztina, NAGY Katalin, SONKODI István, MINÁROVITS János

[The high incidence of oral carcinoma in Hungary is attributed primarily to tobacco and alcohol use. Recently, however, a series of publications suggested a role for humán papillomavirus in the development of oral carcinoma. For this reason we reviewed the literature regarding the associations of human papillomavirus with oral carcinoma and its preblastomatoses. We also overviewed research aiming to develop reliable methods for early diagnosis that are also suitable for screening. Early diagnosis and treatment may significantly improve the prospects of the patient. In addition, the addition of already available human papilloma virus vaccines into national vaccination programs and the extension of vaccination for both sexes may decrease the prevalence of oral carcinoma associated with human papillomavirus infection that primarily affects younger populations.]

[ANALYSIS OF THE KNOWLEDGE ON CERVICAL CANCER AND ATTENDANCE INDICATORS OF CERVICAL SCREENING]

VAJDA Réka, KARAMÁNNÉ Pakai Annamária, ÉLIÁS Zsuzsanna, SÉLLEYNÉ Gyuró Mónika, TAMÁS Péter, VÁRNAGY Ákos, KÍVÉS Zsuzsanna

[OBJECTIVE - The study aims to explore knowledge on cervical cancer and cervical screening among women with 9-14 yearold daughters, and learning the attitudes towards screening, the motivation of attendance at or absence from screening. DATA AND METHODS - A quantitative, cross-sectional study was conducted using our own questionnaire in the town Nagyatád in 2012. Study participants included women who had 9-14 year-old daughters and a registered home address in Nagyatád. We received valid responses from 186 people (response rate: 75.3%). RESULTS - The interviewed women’s knowledge on cervical cancer differed significantly depending on their age, education, marital status, and economic activity. Only 45 women with higher education (p=0.043) were considered to be well informed on the subject. However, their willingness to participate in cancer screening was more favorable than their knowledge, 96.2% of the women claimed to attend an annual cancer screening. The average age of respondents was 20.92 years at first visit. CONCLUSIONS - Although the participation rate was much higher compared with that in previously published studies, it is of great importance to increase the mothers’ knowledge on cervical cancer and the factors that promote its development, so that they can pass their knowledge to their children and strengthen their protection against one of the most common sexually transmitted viral infection and the development of cervical cancer.]

[CONTROVERSIAL ISSUES IN THE TREATMENT OF OPERABLE CERVICAL CANCER]

PETE Imre

[Wertheim hysterectomy as a baseline surgical treatment for patients with FIGO stage 1a2-2a cervical cancer was introduced in 1989 at the National Institute of Oncology, Budapest, Hungary. From then until 2002 when the results were first evaluated 308 such operations were performed. The average 5- and 10-year survival rates were 80% and 75%, respectively. Although these results are comparable to literature data, several issues concerning this group of patients remain to be solved. The participation rate in the Pap test screening programme covered by the national health insurance is only 30%. There is no national database on the current treatment of these patients that could help identify the necessary steps to be taken in order to improve the results. The number of radical hysterectomies performed a year in Hungary, or their outcome, is not known. The treatment scheme varies among the institutes and so does surgical experience. There is no consent regarding treatment policy, preoperative irradiation or chemotherapy, surgical technique, or postoperative management. The improvement of the participation rate in the screening programme, the use of prognostic factors to determine the most appropriate treatment, the role of minimally invasive and fertility-preserving surgery, the preservation of ovaries and the use of neoadjuvant chemotherapy are some of the further issues that need to be discussed. The first step should be data acquisition from all institutes in the country in order to develop and apply uniform treatment guidelines.]
