Oral sex related knowledge and oral sex behavior among homosexual and heterosexual men in Belgrade: A cross-sectional study.

BACKGROUND: Although the risk of sexually transmitted infections is far greater during vaginal and anal sex than during oral sex, increasing practice of oral sex and low rates of barrier method use will probably increase the relative importance of oral sex as a route of transmission for genital pathogens. AIMS: The aim of this study was to evaluate knowledge and attitudes about oral sex and sexually transmitted infections, as well as oral sex practices, both among heterosexuals and homosexual men and to compare those two groups. MATERIALS AND METHODS: In this cross-sectional study, data were collected from consecutive sexually active male patients who ever had oral sex and who attended counselling for sexually transmitted infections at the City Institute for Skin and Venereal Diseases in Belgrade from March to June 2016. One dermatologist interviewed all participants. RESULTS: The study included 359 men who ever had oral sex, 95 (26.5%) homosexual and 264 (73.5%) heterosexual men. In comparison with heterosexual men, homosexual men had considerably more lifetime sexual partners and oral sex partners during the past 3 months, and significantly more frequently practiced oral-anal sex. Oral-sex related knowledge of all participants was unsatisfactory [correct answers were given by 95 (26.5%) to 277 (77.2%) participants], but it was significantly better in homosexual men than in heterosexual. Frequency of condom use and human immunodeficiency virus testing was also significantly higher in the case of homosexual than heterosexual men. LIMITATIONS: The study was not performed in representative sample of population. It was restricted to the patients. Consequently it is questionable whether the results obtained could be generalized. CONCLUSION: Oral sex related knowledge deficits and risky oral sex practice exist in both homosexual and heterosexual men. These findings indicate a need for effective public health campaign and patient education about the risks of unprotected oral sex.

Risk factors for Peyronie's disease: a case-control study.

OBJECTIVE: To test some hypotheses about risk factors for Peyronie's disease (PD). PATIENTS AND METHODS: In a case-control study, 82 patients with PD, consecutively diagnosed at the first author's institution, were compared with 246 men visiting the same institution for dermatological diseases. Univariate and multivariate logistic regression analyses were used to assess the data. RESULTS: From the multivariate logistic regression analysis the risk factors for PD were: a history of genital and/or perineal injuries, transurethral prostatectomy, cystoscopy, diabetes mellitus, hypertension, lipoma, propranolol in therapy, Dupuytren's contracture in the medical history, ever having smoked, alcohol consumption, fibromatous lesions of the genital tract of the partner, and surgical intervention on the genital tract of the partner. CONCLUSION: The results of the present study are in line with the hypothesis that, in addition to genetic predisposition, trauma of the penis and systemic vascular diseases are risk factors for PD. Smoking and alcohol consumption also seem to have some role in the development of the disease.

The Belgrade childhood diabetes study: a multivariate analysis of risk determinants for diabetes.

BACKGROUND: The aim of this study was to evaluate some hypotheses about factors related to the development of type 1 diabetes mellitus. METHODS: A case-control study was conducted in Belgrade during the period 1994-1997. A total of 105 recently onset diabetic and 210 control children, individually matched by age (+/-1 year), sex and place of residence, were included in the study. RESULTS: According to multivariate regression analysis, the following factors were related to type 1 diabetes: stressful events and symptoms of psychological dysfunction during the 12 months preceding the onset of the disease [odds ratio (OR) 3.48, 95% confidence interval (CI) 2.15-5.65; and OR 2.15, 95% CI 1.33-3.48], irregular vaccination (OR 16.98, 95% CI 1.38-208.92), infection during 6 months preceding the onset of the disease (OR 4.23, 95% CI 1.95-9.17), higher education of father (OR 1.50, 95% CI 1.05-2.14), mother's consumption of nitrosoamines-rich food during pregnancy (OR 4.33, 95% CI 1.95-9.61), alcohol consumption by father (OR 3.80, 95% CI 1.64-8.78), insulin-dependent and non-insulin-dependent diabetes mellitus in three generations of children's relatives (OR 20.04, 95% CI 4.73-84.81; and OR 5.52, 95% CI 2.45-12.46), and use of ultrasound diagnostic techniques during pregnancy (OR 0.42, 95% CI 0.17-1.00). CONCLUSIONS: Among non-genetic factors, those affecting the child during pregnancy are especially important because of their preventability.

Sexual behaviour of male teenagers attending a City Department for Skin and Venereal Diseases in Belgrade.

A study of sexual behaviour of teenagers is essential in the design of an effective intervention programme for sexually transmitted diseases (STDs). A questionnaire was administered to 380 men, attending the department for skin and venereal diseases in Belgrade in the period from January 2000 to June 2001. Two groups were compared, 'STD cases' (attending for suspected STDs) and controls (with skin mycotic diseases). In multivariate logistic regression analysis the following risk factors were significantly more frequent in STD cases: sex on the same day as the first encounter (odds ratio (OR)= 2.62, 95% CI = 1.58-4.34), history of previous STD (OR = 3.60, 95% CI = 1.74-7.45) and never using a condom with an irregular partner (OR = 2.19, 95% CI = 1.10-4.38).
