Background: The increase in human immunodeficiency virus (HIV) among men who have sex with men (MSM) in Israel during the last decade raises concerns regarding other sexually transmitted diseases (STD) in MSM, which are yet undetermined.

Objectives: To evaluate the STD burden in MSM and heterosexuals visiting the Tel Aviv walk-in STD clinic.

Methods: Records of all male patients who attended the clinic once were reviewed to identify demographic characteristics, behavioural attributes, and test results.

Results: Between 2002 and 2008, 1064 MSM (22%) and 3755 heterosexuals (78%) visited the clinic once. Positivity rates in MSM for HIV, urethral Neisseria gonorrhoea and infectious syphilis were higher than in heterosexuals (2.5%, 2.5%. 0.7% vs. 0.6%, 1.3%, 0.3%, respectively), while urethral Chlamydia trachomatis was higher in heterosexuals than in MSM (2.7% and 1.4%, respectively). MSM tested in our clinic were younger than heterosexuals (P < 0.001), more commonly circumcised (P = 0.03) and Israeli-born (P < 0.001), used substances during sex (P = 0.04), and had prior STD (P < 0.001), a greater number of sexual partners (P < 0.001), and earlier sexual debut (P = 0.02). The final multivariate results for MSM to be diagnosed with HIV/STD were greater number of sexual contacts, previous diagnosis with STD, and infrequent use of condom during anal intercourse.

Conclusions: MSM visiting the Levinsky Clinic had higher rates of HIV/STD than heterosexual males, which correlated with their higher-risk behaviors. The unique characteristics of MSM found in our study, such as sex work, substance use, previous diagnosis of STD, multiple partners and inconsistent use of condom during anal sex should be addressed with innovative interventions to prevent STD/HIV in the gay community in Israel.

 Background: Short trips to holiday resorts in Mombassa, Kenya, have gained popularity among Israelis since the early 1990s. A cluster of cases of malaria among returned travelers raised concern that preventive measures were being neglected.

Objectives: To characterize the demographic and clinical features of malaria acquired in Kenya, and to assess the adequacy of preventive measures.

Methods: Data were collected from investigation forms at the Ministry of Health. All persons who acquired malaria in Kenya during the years 1999–2001 were contacted by phone and questioned about use of chemoprophylaxis, attitudes towards malaria prevention, and disease course. Further information was extracted from hospital records.

Results: Kenya accounted for 30 of 169 (18%) cases of malaria imported to Israel, and was the leading source of malaria in the study period. Of 30 malaria cases imported from Kenya, 29 occurred after short (1–2 weeks) travel to holiday resorts in Mombassa. Average patient age was 43 ± 12 years, which is older than average for travelers to tropical countries. Only 10% of the patients were fully compliant with malaria chemoprophylaxis. The most common reason for non-compliance was the belief that short travel to a holiday resort carries a negligible risk of malaria. Only 3 of 13 patients (23%) who consulted their primary physician about post-travel fever were correctly diagnosed with malaria. Twenty percent of cases were severe enough to warrant admission to an intensive care unit; one case was fatal.

Conclusions: Measures aimed at preventing malaria and its severe sequelae among travelers should concentrate on increasing awareness of risks and compliance with malaria chemoprophylaxis.

Background: Vaginal symptoms are a leading reason for a patient to visit her gynecologist. Little is known about the prevalence of the different causes of vaginitis and the risk factors for this entity in Israel.

Objective: To determine the prevalence in a gynecologic practice in Israel of the main forms of vaginitis: vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis.

Methods: We evaluated 208 patients presenting with vaginal symptoms to a gynecologic clinic; 100 asymptomatic women who attended the clinic for routine check-up served as controls. Demographic, medical and gynecologic histories were obtained, and a pelvic examination was performed in all patients. Vaginal specimens were tested for pH and amine reaction, smeared for Gram-staining and cultured for yeasts and Trichomonas vaginalis. Bacterial vaginitis was diagnosed using the Nugent scoring system. candida infection was diagnosed by microscopic examination and by culture.

Results: Candida spp. was the most common pathogen, documented by microscopy and culture in 35.5% of symptomatic women and 15% of asymptomatic controls (P < 0.001). Detection by culture only (negative microscopy) was documented in 18.7% of symptomatic patients and 15% of controls (P = 0.5). Bacterial vaginosis (Nugent score ≥ 7) was diagnosed in 23.5% of patients and 13% of controls (P = 0.04). Trichomoniasis was present in 8.1% of symptomatic women and 4% of controls (P = 0.1). The main risk factors were antibiotic use for candidiasis and lack of use of oral contraception and condom use for trichomoniasis.

Conclusion: Candida was by far the most common pathogen detected in our population. A statistically significant difference between patients and controls was noted for the prevalence of microscopically diagnosed candidiasis and bacterial vaginosis.
