The prevalence of sexually transmitted diseases (STD) and risky behaviour patterns were studied in 165 adolescents attending a STD clinic in Jamaica. A standardised structured questionnaire, clinical algorithms for STD and serological tests for HIV and syphilitic infection were applied. High prevalences of risky behaviour including young age at onset of sexual activity, especially in boys, (mean age 12.5 +/- 2.5 years); unprotected sexual intercourse (only 4% used condoms consistently); multiple sexual partners (mean 3.8 +/- 2.4 and 1.8 +/- 1.2 for boys and girls, respectively) were found. Marijuana, used by 60% of the boys, was an independent risk factor for dysuria (adjusted Odds Ratio (OR), 2.0; 95% CI, 1.6-3.4). Repeated episodes of STD (33%), coinfection with HIV (1.2%), syphilis (1.2%) and teenage pregnancy (13%) were prominent findings. Educational strategies which promote behaviour intervention at an early age, frequent and consistent use of condoms, abstinence or delayed onset of sexual activity are essential to reducing the HIV/AIDS and STD risk in adolescents in Jamaica.

Chlamydia trachomatis is the most common sexually transmitted bacterium worldwide. In Western Europe, the prevalence of gonorrhoea has decreased by more than 95% since the 1970ies; "tripper" and syphilis are essentially confined to high-risk groups while genital chlamydial infections affect people of all social classes, but information about chlamydia is still scarce in many European countries. Clinically genital chlamydial infections resemble gonorrhoea (dysuria, discharge, irregular bleeding, dyspareunia, perihepatitis) and may be mistaken for appendicitis. However, Chlamydia trachomatis persists longer and more often asymptomatic than Neisseria gonorrhoeae in the urogenital tract of men and women. About 20% of all chlamydia infected women suffer from partial or complete tubal occlusion. Chlamydia trachomatis is the leading cause of female infertility, but most of these women never experienced any clinical sign of pelvic inflammatory disease. Since particle concentrations are often very low in urine and cervical secretions only DNA-amplification tests, e.g. PCR or LCR, exhibit sufficient sensitivity for direct detection Chlamydia trachomatis. While Neisseria gonorrhoeae is eradicated by single-shot treatment with commonly used antibiotics like penicillins or cephalosporins Chlamydia trachomatis affords treatment for at least 10 days with doxycyline or macrolides. Partner treatment is essential to avoid reinfections. Condoms not only protect against HIV, but also against chlamydia, gonorrhoea and syphilis.

Mumps epididymo-orchitis has not been recorded as a cause of testicular symptoms without systemic features (including parotitis). The aim of the present study was to assess if we were missing cases in the genitourinary clinic during a previous outbreak of mumps in the community. During a prospective pilot study from November 2005 to February 2006, all patients presenting with symptoms or signs of epididymo-orchitis were studied. These patients were assessed for previous exposure to mumps virus or vaccine, and any current evidence of systemic illness. All patients included had a full sexual health screen (loop test, chlamydia polymerase chain reaction [PCR], gonorrhoea culture, HIV and Venereal Disease Research Laboratory [test]/Treponema pallidum particle agglutination assay), urinary tract infection excluded by urinalysis and mid-stream specimen of urine (MSSU) and mumps serology (Immunoglobulin M [IgM] and Immunoglobulin G [IgG]) performed. Twenty-three patients met inclusion criteria. Their ages ranged from 16 to 50 years, average 30.8 years. All had symptoms of these, 18 had testicular pain, eight swelling, (four had both pain and swelling) and three also had dysuria. On examination, 12 had tenderness, seven swelling, (two both tenderness and swelling) and six had no signs. Seventeen denied history of mumps, one patient had a record of vaccination and five described fever. None had parotid swelling. Three patients were chlamydia PCR positive, two had candida cultured, three had non-specific urethritis (>10 polymorphonuclear leucocyte/high powered field) and 13 had negative sexually transmitted infection screen (one known HIV-positive). Three had positive IgM mumps serology and two were IgG-positive. It is important to include mumps in the differential of epididymo-orchitis and to be aware of outbreaks in the community that may present with genital symptoms, as the management and partner notification will be different.

Mycoplasma genitalium is a globally important sexually transmitted pathogen. Men infected with M. genitalium frequently present with dysuria, while women may present with or without urogenital symptoms. In some populations, M. genitalium is significantly associated with HIV-1 infection, and is also an etiological agent in pelvic inflammatory disease. However, there is insufficient evidence to establish a causative role of the organism in obstetric complications, including tubal factor infertility. Although several nucleic acid amplification tests offer rapid, sensitive methods for detecting M. genitalium, there is no standardized assay. Available evidence supports treatment of M. genitalium infections with an extended regimen of azithromycin and resistant strains respond to moxifloxacin. Accumulating evidence indicates growing fluoroquinolone resistance, including against moxifloxacin, emphasizing the need for new therapeutic strategies to treat M. genitalium infections.

Vaginal symptoms are a common chief complaint amongst women visiting outpatient clinics in rural Haiti. A systematic sample of 206 consecutive women over age 18 with gynaecological symptoms underwent gynaecologic examination and laboratory testing for chlamydia, gonorrhoea, syphilis, HIV infection, trichomoniasis, candidiasis, and bacterial vaginosis. Among 206 women, 174 (84%) presented with vaginal discharge, 165 (80%) with vaginal itching, 123 (60%) with vaginal pain or dysuria, and 18 (9%) with non-traumatic vaginal sores or boils. Laboratory results were positive forChlamydia trachomatisin 5.4% (11/203), syphilis in 3.5% (7/202), HIV in 1.0% (2/200), andNeisseria gonorrhoeaein 1.0% (2/203). Among those that had microscopy, hyphae suggestive of candidiasis were visualized in 2.2% (1/45) and no cases of trichomoniasis were diagnosed 0% (0/45). Bacterial vaginosis was diagnosed in 28.3% (13/46). The prevalence of chlamydia was 4.9 (95% CI: 1.3-17.7) times greater among those 25 years of age and under (10.8%) than those older (2.3%). Chlamydia and bacterial vaginosis were the most common sexually transmitted infection and vaginal condition, respectively, in this study of rural Haitian adult women. The higher risk of chlamydia in younger women suggests education and screening programmes in young women should be considered.

Kounis syndrome is characterised by a group of symptoms that manifest as unstable vasospastic or non-vasospastic angina secondary to a hypersensitivity reaction. It was first described by Kounis and Zavras in 1991 as the concurrence of an allergic response with an anaphylactoid or anaphylactic reaction and coronary artery spasm or even myocardial infarction. Since then, this condition has evolved to include a number of mast cell activation disorders associated with acute coronary syndrome. There are many triggering factors, including reactions to multiple medications, exposure to radiological contrast media, poison ivy, bee stings, shellfish and coronary stents. In addition to coronary arterial involvement, Kounis syndrome comprises other arterial systems with similar physiologies, such as mesenteric and cerebral circulation resulting in ischaemia/infarction of the vital organs. The incidence of this condition is difficult to establish owing to the number of potential instigating factors and its relatively infrequent documentation in the literature.We report the case of an HIV-negative 39-year-old man with no coronary risk factors or family history of premature coronary artery disease, who developed Kounis syndrome after the administration of fluoroquinolone for dysuria. However, to the best of our knowledge,no data on the incidence and prevalence of Kounis syndrome in South Africa have ever been reported in the literature. The recent understanding of Kounis syndrome has led to the condition being classified into three syndrome variants.

Herpes simplex virus (HSV) is the leading cause of proctitis in HIV-infected individuals. However, no cases of rectal masses secondary to HSV infection have been reported to date. Herein, we present the case of a 45-year-old man with HIV infection who developed rectal pain and bleeding, along with dysuria and voiding difficulty. Colonoscopy revealed proctitis and a rectal mass with features concerning for rectal cancer. Histologic sections of the rectal mass biopsy demonstrated colorectal mucosa with viral cytopathic changes, ulceration, granulation tissue, marked inflammatory infiltrate, and fibrinopurulent exudate. Immunohistochemistry for herpes simplex virus-1 was positive in epithelial cells demonstrating a viral cytopathic effect. The patient was treated with valacyclovir for 3 weeks, which led to complete resolution of his symptoms. Follow-up sigmoidoscopy at 6 months did not show any masses. Our case illustrates the importance of considering HSV in the differential diagnosis of rectal masses. We advocate the routine use of viral immunohistochemistry for the evaluation of rectal tumors, especially in patients with clinical manifestations and endoscopic findings consistent with proctitis.

Objective: The aim of this study was to assess the sexual health knowledge among females seeking consultation in behavioral clinics or shelters with emphasis on sexual routs of HIV transmission. Materials and methods: In this study 250 women who have attended behavioral clinics or shelters in Tehran were recruited and a standardized questionnaire which asked about demographics, sexual partner and knowledge about HIV/STDs was used. Results: The median age of our cases was 40.82% and among them 16% were married but lived alone. Among the total 250 cases, 56% (140) were sexually active in the last 30 days, 19.2% (48) had a history of a one-night stand and 2.4% had more than 1 sexual partner. 212 cases answered questions about condom use, 60% (127) of them did not use condoms at all. For knowledge about signs and symptoms related to STDs, 63% believed that abdominal pain has no relation to STDs. Also 44%, 43%, 37%,and 40% believed that dyspareunia, dysuria, malodorous vaginal discharge and change in color of vaginal discharge, respectively had no relation to STDs and 13% of whom presented with these symptoms in the past 30 days had not seek medical evaluation. Conclusion: It is a necessity to emphasize the use of condoms among the male population however in this study it was a challenge to do so because it goes against the government's campaign of pro-natalism. Improving the knowledge of protected sex should start from the teenage years and at school to have maximum STD prevention planning. Most women in our study did not know about healthy sexual lifestyle and this shows the need of sexual health education before marriage or even at school.
