Opting off the New South Wales Pap Test Register in a sexual health setting.

OBJECTIVES: To determine the proportion of women having a Pap smear at Sydney Sexual Health Centre (SSHC) who opted off the NSW Pap Test Register (PTR) and to establish the characteristics of these women. DESIGN: Retrospective cross sectional study involving three time periods during 1996 and 1997. SETTING: A public sexual health centre in Sydney. PARTICIPANTS: 985 women who had a Pap smear at SSHC. MAIN OUTCOME MEASURES: The participant's decision to opt on or off, and the demographic and behavioural characteristics associated with opting off the PTR. RESULTS: 590 (59.9%) women opted off the PTR. Using logistic regression, young age (p=0.005), birth outside Australia and New Zealand (p=0.0001), not speaking English at home (p=0.005) and being a commercial sex worker (CSW) (p=0.0001) were variables associated with opting off the PTR. Women from countries outside of Australia and New Zealand were more likely to opt off, whether or not they were a CSW and CSWs were more likely to opt off the PTR irrespective of their country of birth (p=0.013). CONCLUSION: The majority of women (60%) attending the SSHC opted off the PTR. Studies to evaluate culturally appropriate health promotion material particularly for CSWs and women with poor English skills living in Australia are needed and if successful may improve uptake on the PTR.

Sexual and demographic risk factors for herpes simplex type 1 and 2 in women attending an antenatal clinic.

OBJECTIVE: To establish risk factors for the presence of HSV-2 and HSV-1 infections in pregnant women. DESIGN, POPULATION, AND SETTING: A prospective study of 3306 women attending the antenatal department Westmead Hospital, Sydney, between June 1995 and April 1998. METHODS: Women completed a self administered questionnaire to establish risk factors for the presence of HSV-2 and HSV-1. Sera were tested for antibodies to HSV-2 and HSV-1. Data were analysed using SPSS and SAS. MAIN OUTCOME MEASURES: Seroprevalence of and risk factors for HSV-2 and HSV-1. RESULTS: 375 (11.3% (95% CI 10.3-12.5)) women were HSV-2 antibody positive. Increasing age, Asian country of birth, lower education level, public hospital status, confirmed genital herpes, a partner with genital herpes, early age of first sex, more than one lifetime sexual partner, and previous chlamydia infection were independently associated with HSV-2 seropositivity. Of 408 women tested for HSV-1 antibodies, 323 (79.2% (95% CI 74.9-83.0)) were positive. Oral herpes, oral blisters or sores, and being HSV-2 seropositive were independently associated with HSV-1 seropositive status. When the logistic regression model was rerun without HSV-2 status, parity of two or more and one or more sexual partners in the past 3 months were significant predictors of HSV-1 seropositivity. CONCLUSIONS: The presence of antibodies to HSV-2 and HSV-1 is related to a number of sexual and demographic risk factors. Public health campaigns directed at encouraging young people to delay the onset of sexual activity and reduce the number of sexual partners need to be evaluated. However, the possible availability of an HSV-2 vaccine that is able to protect over 70% of women offers the best hope for control of genital herpes.

Use of complementary therapies in a sexual health clinic setting.

This prospective cohort study examined the health-seeking behaviour of patients diagnosed with genital warts and vulvodynia who presented to Manly Sexual Health Service from March to June 2000. A self-administered questionnaire was used to assess patients' perceptions of their condition and their use of complementary therapies. Thirty-seven patients with genital warts and 26 patients with vulvodynia participated in the study. The use of at least one complementary health product or method was reported by 59% of patients with genital warts and 96% of vulvodynia patients (P < 0.001). Having received conflicting information and being worried about the condition was significantly associated with visits to complementary health providers. Acknowledgement of this search for complementary therapies and open discussion can help patients make informed decisions and to avoid drug interactions, and should ultimately lead to better patient care.

Male clients of female commercial sex workers: HIV, STDs and risk behaviour.

Social stigma and taboo limit current understanding of sexual behaviours and epidemiology of sexually transmitted infections (STIs) in clients of commercial sex workers/prostitutes. We designed a study to determine risk behaviours and prevalence of STIs in a group of sexual health clinic attending male clients of female commercial sex workers (FCSWs) in Sydney, and to compare these characteristics with men who denied any commercial sexual contact. Eight hundred and ninety cases and 2670 controls were included. Clients of FCSWs were older, more likely to be married and of non-English speaking background than controls. Clients had more sexual partners but reported more condom usage than controls. Prevalence of STIs at presentation was lower in clients than controls but clients were more likely to report STIs in the past than controls. HIV prevalence was low in both groups.

Prospects for control of herpes simplex virus disease through immunization.

Herpes simplex viruses (HSVs) can cause a variety of infections, including genital herpes. Despite effective antiviral therapy, HSV infections remain a significant worldwide public health problem. Vaccines offer the best hope for controlling spread and limiting HSV disease. This article discusses the pathogenesis and immunobiology of mucocutaneous HSV infections, summarizes the spectrum of diseases caused by HSV, and provides a review of the field of HSV vaccine research. This article also discusses what might be realistically expected of a vaccine intended for control of genital herpes and explores the question of whether a vaccine that is effective in controlling genital HSV disease might also be effective in controlling nongenital HSV disease. The efficacy of such vaccines for the full spectrum of HSV disease will eventually determine the timing and targeting of immunization, ranging from selective immunization in preadolescence to universal childhood immunization as part of the routine childhood regimen.

Neonatal herpes prevention: a minor public health problem in some communities.

BACKGROUND: Neonatal herpes is a condition with high morbidity and mortality. The greatest risk occurs when the mother acquires herpes simplex virus (HSV) towards the end of pregnancy. A study from Seattle has suggested that the risk of acquisition of HSV during pregnancy was 3.7%. In Australia, HSV-2 infection is less common in pregnant women than in the United States. Consequently we conducted a study to establish HSV seroprevalence and the rate of HSV seroconversion in this population. METHODS: The study was conducted at Westmead Hospital, Sydney, between June 1995 and April 1998. Women completed a questionnaire covering risk factors for the acquisition of genital herpes. A serum sample during pregnancy and a specimen of cord blood were obtained and tested for antibodies to HSV-2 using a type specific indirect enzyme linked immunosorbent assay (ELISA). Equivocal results were resolved by western blot. A subset of the paired sera was tested for antibodies to HSV-1. The data were analysed using SPSS. RESULTS: 326 of the 2616 (12.5%) women were HSV-2 seropositive. Three women (0.15%) acquired HSV-2 infection during pregnancy. None of the three babies of these mothers developed neonatal herpes. 416 maternal cord pairs were tested for HSV-1 antibodies and 330 (79.3%) were positive. No HSV-1 seroconversions occurred. CONCLUSIONS: In this population, HSV acquisition was uncommon (0.34% per year) and neonatal herpes was rare. A cost effective analysis suggested that type specific serology to screen pregnant women and their partners in low prevalence communities was not cost effective.

HIV, sexually transmitted infections, and risk behaviours in male commercial sex workers in Sydney.

OBJECTIVES: To assess prevalence of HIV and sexually transmitted infections (STIs), risk behaviours, and demographics in male commercial sex workers (CSWs)/prostitutes in Sydney. METHODS: Retrospective, cross sectional study with two comparison groups. Demographic, behavioural, and morbidity data were analysed from standardised medical records of patients attending a public STI and HIV service in Sydney between January 1991 and March 1998. Two comparison groups were used: female CSWs and non-CSW working homosexual men who attended over the same time. RESULTS: 94 male CSWs, 1671 female CSWs, and 3541 non-CSW working homosexual men were included. The prevalence of HIV in male CSWs tested (6.5%) was significantly greater than in female CSWs (0.4%, p = 0.0001), but less than in non-CSW homosexual men (23.9%, p < 0.0001). Genital warts occurred significantly more frequently in male CSWs than in comparison groups. Prevalence of other STIs was similar in all groups. Male CSWs saw significantly fewer clients per week than female CSWs and male and female CSWs used condoms with almost all clients. Male CSWs reported significantly more non-work sexual partners than female CSWs and non-CSW homosexual men and were significantly more likely to have unprotected penetrative sex with their non-work partners than non-CSW homosexual men. Injecting drug use was significantly more frequent in male CSWs than in both comparison groups. CONCLUSIONS: Although male CSWs use condoms with clients, they are more likely to practise unsafe sex with non-work partners (especially women) and inject drugs than female CSWs and non-CSW homosexual men. Some men with HIV are working within the commercial sex industry. Targeted health education to encourage safer drug use and safer sex outside work is needed.

Sexually transmitted infections and risk behaviours in women who have sex with women.

OBJECTIVES: To assess the prevalence of sexually transmitted infections (STIs) and blood borne viruses, risk behaviours, and demographics in women who have sex with women (WSW). METHODS: Retrospective cross sectional study using a multivariate model. Demographic, behavioural, and morbidity data were analysed from standardised medical records of patients attending a public STI and HIV service in Sydney between March 1991 and December 1998. All women with any history of sex with a woman were compared with women who denied ever having sex with another woman (controls). RESULTS: 1408 WSW and 1423 controls were included in the study. Bacterial vaginosis (BV) was significantly more common among WSW (OR 1.7, p < 0.001). Abnormalities on cervical cytology were equally prevalent in both groups, except for the higher cytological BV detection rate in WSW (OR 5.3, p = 0.003). Genital herpes and genital warts were common in both groups, although warts were significantly less common in WSW (OR 0.7, p = 0.001). Prevalence of gonorrhoea and chlamydia were low and there were no differences between the groups. The prevalence of hepatitis C was significantly greater in WSW (OR 7.7, p < 0.001), consistent with the more frequent history of injecting drug use in this group (OR 8.0, p < 0.001). WSW were more likely to report previous sexual contact with a homo/bisexual man (OR 3.4, p < 0.001), or with an injecting drug user (OR 4.2, p < 0.001). Only 7% of the WSW reported never having had sexual contact with a male. CONCLUSION: We demonstrated a higher prevalence of BV, hepatitis C, and HIV risk behaviours in WSW compared with controls. A similar prevalence of cervical cytology abnormalities was found in both groups. Measures are required to improve our understanding of STI/HIV transmission dynamics in WSW, to facilitate better health service provision and targeted education initiatives.

Assessment of risk for pelvic inflammatory disease in an urban sexual health population.

OBJECTIVES: To determine the sexual and demographic risk factors for the acquisition of presumptive pelvic inflammatory disease (PID). METHODS: A retrospective, case-control study in women, who attended the Sydney Sexual Health Centre (SSHC), between April 1991 and December 1997. Logistic regression analysis was used to adjust for confounding variables. RESULTS: 741 women with PID and an equal number of controls were included. Cases were significantly younger than controls (p < 0.001). 42% of cases were born in north or South East Asia, compared with 12% of the controls (p < 0.001). The adjusted odds ratio for being born in north or South East Asia was 2.8 (95% CI 1.70-4.46), for not speaking English at home was 1.6 (95% CI 1.02-2.55), for having had previous PID was 5.9 (95% CI 3.59-9.73), and for being employed in the commercial sex industry and being born in north or South East Asia was 2.8 (95% CI 1.22-6.22). Women aged 15-19 were at considerable risk of developing PID (OR 5.3 (95% CI 2.76-10.11)). Women with previous human papillomavirus infection were significantly less likely to develop PID (OR 0.6 (95% CI 0.42-0.79)). The use of IUCDs (OR 4.5 (95% CI 2.14-9.39)), condoms (OR 1.4 (95% CI 1.03-1.87)), and not using contraception (OR 1.8 (95% CI 1.20-2.76)) was each associated with an increased risk. CONCLUSIONS: Several measures may help to reduce the burden of PID. Women should be encouraged to delay the onset of sexual activity and IUCDs should not be used in young women. Sexual health services for women whose home language is not English, and for commercial sex workers born in north or South East Asia should be improved.

Herpes simplex virus type 2 in prisoners, New South Wales, Australia.

Our objectives were to determine the prevalence of, and risk factors for, herpes simplex virus type 2 (HSV-2) antibodies in male and female prisoners. A cross-sectional random sample was used consisting of 789 prisoners (657 males and 132 females) from 27 correctional centres across New South Wales (NSW), stratified by sex, age and Aboriginality. Participants were questioned about demographics and behavioural risk factors and were screened for serum antibody to HSV-2. The overall prevalence of HSV-2 antibodies was higher in females (58%) than males (21%), and in Aborigines (34%) compared with non-Aborigines (24%). HSV-2 prevalence increased with the number of sexual partners. Few prisoners (1%) reported a previous diagnosis of genital herpes. Independent risk factors for the presence of HSV-2 antibodies were increasing age and Aboriginality for men, and higher reported number of lifetime sexual partners and the presence of hepatitis C antibodies for women. HSV-2 infection is common in prison inmates. There is a need to incorporate information about STDs, including HSV-2, into education programmes for inmates.

Diagnosing PID--getting the balance right.

The objective of the study was to determine the clinical manifestations and diagnostic criteria used to diagnose presumptive pelvic inflammatory disease (PID) at the Sydney Sexual Health Centre (SSHC). The study was a retrospective, case-note review of all women diagnosed with presumptive PID between April 1991 and December 1997. Seven hundred and thirteen women were included. The commonest recorded symptoms were vaginal discharge (68%), lower abdominal pain (65%) and dyspareunia (57%), while adnexal tenderness (83%), cervical motion tenderness (75%) and cervicitis (56%) were the most frequently recorded examination findings. Sixty-two per cent were prescribed doxycycline and metronidazole. The recording of signs and symptoms in women with presumptive PID was poor and only 22% met the current Centers for Disease Control (CDC) diagnostic criteria. It is likely that PID is over diagnosed in this group of women. This may lead to under diagnosis of other conditions causing pelvic pain and may be detrimental to reproductive health.

New developments in the epidemiology, natural history and management of genital herpes.

The prevalence of genital herpes is increasing in several populations worldwide. Factors that may be contributing to this increase include greater numbers of sexual partners, the high frequency of asymptomatic infections, poor use of safe sexual practices, and possibly the decreased incidence of childhood oral herpes simplex virus infection. Transmission occurs via skin-to-skin or mucous membrane contact during periods of viral shedding when lesions are present but may also occur when the patient is unaware of the lesions or when lesions are not clinically apparent. This has important implications for strategies to prevent transmission of the disease. The introduction of the antiherpes agent, acyclovir, and more recently famciclovir and valacyclovir, facilitates the management of genital herpes. Treatment of first-episode genital herpes reduces the severity and duration of symptoms, time to lesion healing, and cessation of viral shedding. Episodic treatment of recurrences as they occur may be of benefit to some patients. Daily suppressive therapy significantly reduces the frequency of recurrences and asymptomatic viral shedding. Accordingly, patients who experience frequent or severe recurrences, those particularly troubled by their disease, and those who wish to reduce the frequency of asymptomatic infection generally prefer suppressive therapy. The possibility that suppressive therapy may have an impact on transmission of the disease is currently under investigation. Antiviral treatments have important implications for public health and may help reduce the psychological and psychosocial impact of genital herpes on individual patients.

Management of women with recurrent genital herpes in pregnancy in Australia.

OBJECTIVE: To document clinical practice for the management of recurrent genital herpes in pregnant women in Australia. DESIGN AND PARTICIPANTS: A questionnaire to all doctors associated with the Royal Australian College of Obstetricians and Gynaecologists. MAIN OUTCOME MEASURES: Policies for antenatal herpes screening, circumstances in which delivery by caesarean section was considered appropriate, and the use of aciclovir during pregnancy. The results were analysed by college status, sex, and whether the doctor worked in a public or private facility. RESULTS: 2855 (67.3%) obstetricians returned questionnaires. 696 (34.3%) stated that their hospital had a policy for managing recurrent genital herpes in pregnancy: 44.5% examined the genitalia and 33.8% took cultures during pregnancy. Fellows were more likely to examine the genitalia (87% v 37%, p < 0.001), and more likely to perform antenatal viral cultures than members (75% v 30%, p < 0.001). Doctors working at private hospitals were significantly more likely to take viral cultures than doctors in public hospitals (39% v 33% p < 0.05). Doctors were asked to consider five scenarios and judge whether caesarean section would be appropriate. 96% considered that a caesarean section was appropriate in women with active herpes at the onset of labour. In the case of a recurrence of genital HSV at the time of presentation with ruptured membranes longer than 4 hours, diplomats (79%) were significantly more likely to recommend a caesarean section than fellows (64%), members (63%), or trainees (49%) (all p < or = 0.001). Where there were positive viral cultures before the onset of labour fellows (45%) were more likely than members (29%) (p = 0.005), males (62%) were more likely than females (55%) (p = 0.03), and doctors working in private hospitals (69%) were more likely than those in the public sector (54%) (p < 0.001) to recommend caesarean section. CONCLUSION: There is considerable divergence of opinion regarding the appropriate management of recurrent genital herpes in pregnancy. The implementation of management guidelines would provide consistency of care.

Risk factors for the acquisition of genital warts: are condoms protective?

OBJECTIVES: To characterise risk factors for the acquisition of genital warts and specifically to determine whether condoms confer protection from infection. METHODS: A retrospective case-control study comparing demographic, behavioural, and sexual factors in men and women with and without newly diagnosed genital warts, who attended Sydney Sexual Health Centre (SSHC), an inner city public sexual health centre, in 1996. Data were extracted from the SSHC database. Crude odds ratios (OR) were calculated to compare cases and controls and significant factors were then controlled for using multivariate logistic regression to obtain adjusted odds ratios (ORs). RESULTS: 977 patients with warts and 977 controls matched by sex and date of attendance were included. In both sexes, univariate analysis revealed that younger age, more lifetime sexual partners, failure to use condoms, greater cigarette smoking and alcohol consumption were associated with warts, and there was a negative association with previous infection with Chlamydia trachomatis, Neisseria gonorrhoeae, hepatitis B, and genital herpes. In males, on multivariate analysis, factors which remained significant were younger age, more lifetime sexual partners; failure to use condoms, greater cigarette smoking, and previous chlamydia. In women, factors which remained significant were younger age, more lifetime sexual partners, condom use, marital status, and previous infections with Chlamydia trachomatis and herpes. CONCLUSIONS: Independent risk factors for genital warts include younger age, greater number of lifetime sexual partners, and smoking. Consistent condom use significantly reduces the risk of acquiring genital warts.

Young working women utilise the after hours service at Sydney Sexual Health Centre.

OBJECTIVE: To analyse patterns of patient utilisation of the after hours service at Sydney Sexual Health Centre (SSHC). METHOD: A retrospective cross sectional database study compared all new daytime and after hours patients who registered for a medical consultation at SSHC between August 1994 and February 1995. Daytime and after hours attenders were compared using demographic and behavioural factors and for prevalence of STDs and HIV using logistic regression analysis. RESULTS: Of the 1662 eligible patients, 1362 (81.9%) attended during daytime hours, and 300 (18.1%) attended after hours. There was no significant difference in after hours attendance between patients living in inner compared with outer metropolitan zones. Using logistic regression analysis, being female (p = 0.0008), being between 20 and 39 years of age (p = 0.008), being employed (p < 0.001), and having no previous STD/genitourinary condition (p = 0.034) were the factors significantly associated with after hours attendance. CONCLUSIONS: The evening service was disproportionately utilised by a patient group not defined as "high risk" in the objectives of the service. This study challenges the assumption that evening clinics are always the way to reach high risk groups.
