In 2004, the Newcastle genitourinary medicine clinic launched a new website. To assess its value to users and impact on service demand, we surveyed those attending the clinic with a new episode between September and December 2005 by a questionnaire. One hundred and fifteen of 601 respondents (19%) visited the website. Fifty-nine percent of users were men with those aged between 35 and 44 ranking the highest percentage (31.7%) among those who visited the website. Fourteen (12.5%) would not have attended if they had not visited the website. One hundred and two (88.7%) found it easy to use and 81 (70.4%) looked for specific information of whom 73 (89%) were successful. Web users were more likely to present with an episode not requiring treatment possibly indicating increased demand promoted by our prevention information but less likely to have bacterial vaginosis, anaerobic balanitis and anogenital candidosis (not statistically significant).

The relative effect of HIV-1 infection compared with vaginal infections on vaginal cytokine concentrations is not well characterized. We compared vaginal fluid samples from HIV-1-infected women with those from HIV-negative women, to assess the effect of HIV-1 infection on concentrations of vaginal proinflammatory cytokines and the mucosal defense molecule secretory leukocyte protease inhibitor (SLPI). Twenty-seven HIV-1-infected women and 54 HIV-negative controls, matched for bacterial vaginosis (BV) status, had proinflammatory cytokine [interleukin (IL)-1beta, IL-6, IL-8] and SLPI concentrations measured from archived cervicovaginal lavage and vaginal swab samples using an enzyme-linked immunosorbent assay (ELISA). Log-transformed concentrations were compared by BV and HIV status in univariate analysis using Student's t-test, and in multivariate analysis using a linear regression model. In univariate analysis there were no significant differences in cytokine concentrations among HIV-1-infected and HIV-negative women. In a multivariable linear regression model, BV was significantly associated with an increase in IL-1 beta (p = 0.003). HIV infection was associated with an increased concentration of SLPI (p = 0.008), while BV status was significantly associated with a decrease in SLPI concentrations (p = 0.005). Neither HIV nor BV was associated with changes in IL-6 or IL-8. HIV does not have a major impact on vaginal concentrations of proinflammatory cytokines when controlling for the presence of bacterial vaginosis.

The aim of this study was to determine HIV-1 incidence among women of reproductive age in Malawi. A prospective study design was followed. HIV-1 uninfected women were followed up for nine visits during a period of 12 months. At baseline, women received HIV-1 counselling and testing. At each visit, venous blood was collected for HIV-1 testing. Incidence rate for HIV-1 was estimated using person-years of follow up (PYFU). Risk factors for HIV acquisition were assessed using Cox proportional hazard models. A total of 842 HIV-1 negative women were enrolled in the study. Of these, 787 had subsequent HIV testing and 31 were found HIV-1 infected; an overall incidence rate of 4.51 (95% confidence interval: 2.96-6.06) per 100 PYFU was obtained. Young age, using hormonal injectable contraceptives and bacterial vaginosis were the main predictors of HIV acquisition. The incidence of HIV continues to be high among women in Malawi, and young women appear to be at higher risk.

Women reluctant to undergo a per-speculum examination consider self-sampling more acceptable. The aim of this study was to compare self-collected vaginal swabs for detection of bacterial vaginosis (BV), candidiasis and trichomoniasis, with vaginal specimens obtained by the gynaecologist at per-speculum examination. Self-collected and provider-collected vaginal swabs were obtained from 50 women attending the gynaecological outpatients department. The Gram-stained smears and saline wet mounts prepared from the provider-collected vaginal swabs were examined by a microbiologist and a gynaecologist. We determined the validity and the inter-rater reliability of the overall BV score and the morphotype specific score using Kappa statistics. When compared with the provider-collected smear, the ability of the self-collected smear to diagnose BV had a sensitivity of 70% and a specificity of 97%. With specific instructions to help assure the depth of sampling, self-collected swabs can reasonably approximate specimens obtained by clinicians during speculum examination for the diagnosis of BV.

The objective of the study was to determine the prevalence of Mycoplasma genitalium in a sample of health clinic attendees complaining of vaginal discharge. A subsample of 399 vaginal and cervical swabs was randomly selected from 2579 samples collected during a study to determine the causes of vaginal discharge in women attending primary health-care clinics in Dhaka, Bangladesh. Cervical samples were tested for M. genitalium by polymerase chain reaction. In addition, the samples were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, bacterial vaginosis and candida. M. genitalium was detected in three samples (0.8%; 95% confidence interval: 0.00-1.6). The prevalence of C. trachomatis, N. gonorrhoeae T. vaginalis, bacterial vaginosis and candida was 1.3, 3.8, 8, 23.25 and 32.5%, respectively. Two women with M. genitalium were co-infected with T. vaginalis or candida. This is the first study to document the existence of M. genitalium in Bangladesh. Although the prevalence of this infection is low in the population tested, further research into this pathogen in other Bangladeshi populations is justified.

The objective of the present study was to assess infections and cytologic abnormalities in cervicovaginal smears from 153 HIV-positive women and 169 HIV-negative followed up at the UFTM School of Medicine between May 1999 and May 2002. The medical records and cervicovaginal smears were reviewed and the HIV-positive group was classified according to CD4 cell count, HIV viral load, antiretroviral therapy and HIV subgroups (with or without disease; with or without therapy) and compared to HIV-negative group. We conclude that the frequency of Candida sp, Trichomonas vaginalis and bacterial vaginosis in cervicovaginal smear, is not different between HIV-positive and HIV-negative women, even if the HIV-group is subdivided according to CD4 cell count, HIV viral load, antiretroviral therapy and HIV subgroups. The frequency of LSIL, in cervicovaginal smears, was greater in the HIV-group (17.6%) than in the HIV-negative (4.1%); there was no difference between the two groups according to frequency of HSIL (4.6% versus 1.8%), ASCUS/AGUS (7.8% versus 3.5%) and invasive carcinoma (1.3% versus 0.6%). The frequency of LSIL was greater in the HIV positive group with CD4 cell count < 350 cells/mm(3). The viral load, therapeutic regimen and HIV subgroups (HIV-positive without therapy, HIV-positive with therapy, AIDS by immunological criteria and AIDS by clinical criteria) have not shown relationship with LSIL frequency, until now.

This study was undertaken to establish reliable factors in order to identify chlamydial cervicitis among suspicious patients. Between January and December 2007, 406 patients who were suspected to have cervicitis due to clinical symptoms, were tested with polymerase chain reaction (PCR) for Chlamydia trachomatis (CT), vaginal pH and Nugent score (NS) in our University hospital and related clinics. During the same period, 67 patients who were diagnosed as having other sexually transmitted diseases (Neisseria gonorrhoeae (NG), Trichomonas vaginalis, Condyloma acuminatum and genital herpes) were also made to participate in this study. Eighty-nine women (22%) were positive for CT PCR. Bacterial vaginosis (BV)-positive women were tested positive for CT PCR (75/288), significantly higher than those without BV (6/66, P = 0.01). In addition, under 20-years old women were positive for CT PCR (24/57), significantly higher than those who were over 30 years old (16/113, P = 0.001). The proportion of patients with high NS (>7) in CT, NG and T. vaginalis cases were 75/89 (84.3%), 22/27 (81.5%) and 11/14 (78.6%), respectively. Whereas the high NS of the C. acuminatum and genital herpes groups were recorded at 7/14 (50%) and 4/12 (33.3%), respectively. Younger women with BV could be at a higher risk for STDs, especially for CT cervicitis.

The copper intrauterine contraceptive device (IUCD) is strongly associated with bacterial vaginosis (BV). Hormonal influences may play a role in the control of vaginal flora. It is unclear whether use of the progesterone-incorporated intrauterine system (IUS; Mirena) is associated with abnormal vaginal flora or genital symptoms. One hundred and seventy-two women were assessed for symptoms and abnormal vaginal flora prior to and at intervals after insertion of either a copper IUCD or an IUS. Women were significantly more likely to have developed an abnormal vaginal discharge 4-6 weeks after insertion of an IUCD compared with an IUS (27% cf. 14%, P = 0.04), although this trend was not significant six months postinsertion. More women with an IUCD developed BV compared with an IUS at 4-6 weeks and six months. However, there were insufficient numbers of women with BV to demonstrate any significant difference between the vaginal flora of the two groups.

Bacterial vaginosis (BV) is a common disorder of the genital tract in women characterized by an alteration of the normal acidic lactobacilli-predominant vaginal ecosystem to a vaginal environment dominated by Gardnerella vaginalis, mycoplasma species and anaerobes, with an increase in pH. The present study evaluated whether BV is associated with reproductive complications in women. BV was screened with a Gram stain of vaginal smear and interpretation was done using the Nugent score. Wet mount and polymerase chain reaction were used to screen other infections. Among 510 enrolled women, 72 (14.1%) had BV. Statistical analysis between the BV negative and positive population revealed a significant association (P = 0.0001) with infertility. In pregnant women, the infection rate was low (P = 0.01). Multiple infections such as Candida, Chlamydia and human papilloma virus were observed in 4.2%, 15.3% and 8.3% of BV-infected women, respectively. Results suggest that BV infection is associated with infertility and its absence leads to pregnancy, emphasizing its screening and treatment.

HIV-1 transmission in utero accounts for 20-30% of vertical transmission events in breast-feeding populations. In a prospective study of 463 HIV-1-infected mothers and infants, illness during pregnancy was associated with 2.6-fold increased risk of in-utero HIV-1 transmission [95% confidence interval (CI) 1.2-5.8] and bacterial vaginosis with a three-fold increase (95% CI 1.0-7.0) after adjusting for maternal HIV-1 viral load. Interventions targeting these novel risk factors could lead to more effective prevention of transmission during pregnancy.
