Patient assessment of anogenital warts and the success of treatment with home applied therapy.
Home treatment with podophyllotoxin or imiquimod are commonly prescribed therapies for anogenital warts. It is important to ascertain if patients are locating all lesions for treatment and if they know when they are clear of them. We set out to assess patients' ability to determine the number and location of their genital warts and compare their observation with that of their examining doctor or nurse. Following instruction on the use of home treatment and being given an instruction leaflet patients were reviewed in four weeks' time. One hundred and fifty-five patients enrolled in the study--31% (48) male, 69% (107) female. At initial assessment 62.5% (30) of male patients and 59.8% (64) of female patients underestimated the extent of their disease: 10.5% (5) of male patients and 10.3% (11) of female patients overestimated their disease burden with some mistaking skin tags for genital warts. At review 29.4% (5) of male patients and 44.4% (20) of female patients still underestimated the extent of their infection. Patients undertaking home treatment for warts not only need detailed instruction on its use but should be reviewed to assess the success of treatment.

Imiquimod 5% cream is an acceptable treatment option for external anogenital warts in uncircumcised males.
OBJECTIVES: To determine the safety and efficacy of imiquimod (Aldara) 5% cream in the treatment of prepuce-associated warts in uncircumcised males. METHODS: An open-label study in six UK medical centres with 35 uncircumcised males with prepuce-associated warts treated with imiquimod 5% cream three times per week for up to 16 weeks. Other anogenital warts were also treated. RESULTS: Three times weekly application of imiquimod was found to be safe, with erythema as the most commonly reported local skin reaction. Forty per cent of patients had complete clearance of anogenital warts within 16 weeks. CONCLUSIONS: Imiquimod cream at a dosing regimen of three times per week, is effective and has an acceptable safety profile in the treatment of prepuce associated warts and other external anogenital warts in uncircumcised males.

Chronic prostatitis/chronic pelvic pain syndrome: national survey of genitourinary medicine clinics.
We sought to determine current practice in the diagnosis and management of chronic prostatitis/chronic pelvic pain syndrome (CPPS) in genitourinary medicine departments in the UK, using a detailed questionnaire survey. Evaluable responses were received from 147 (69%) clinics. Seventy-nine (54%) clinics reported seeing >10 new CPPS patients per year. A broad range of investigations was reported to be used in the diagnosis of CPPS. Whilst 89 (61%) clinics reported using the four-glass test in diagnosis, 46 (32%) reported using the test in >90% of patients with CPPS, and 42 (29%) reported never using the test. In the treatment, doxycycline or ciprofloxacin were reported to be first line treatment by 98% clinics, mostly in 4-6 week courses; however, great variation was recorded in second-line choices and use of non-antibiotic approaches. This survey demonstrates that patients with CPPS are regularly diagnosed and managed in genitourinary clinics in the UK, with wide variations in diagnostic and treatment practices.

Genital schistosomiasis.
Schistosomiasis is the most serious helminthic infection in the United Kingdom. Female genital schistosomiasis affects 9-13 million women worldwide, mainly in areas where Schistosoma haematobium is endemic. With increasing tourism to these areas, this diagnosis is being encountered more frequently in the West. We present 2 cases of vulval schistosomiasis that were presented to our department in 1999 and 2000.

Imiquimod 5% cream is a safe and effective self-applied treatment for anogenital warts--results of an open-label, multicentre Phase IIIB trial.
Our objective was to determine the efficacy and safety of imiquimod 5% cream in the treatment of external genital/perianal warts in an open-label Phase IIIB trial. Patients applied imiquimod 5% cream 3 times per week, for up to 16 weeks. Those who cleared their warts were monitored during a 6-month follow-up period. If their warts recurred, or new warts developed during this time, patients could be re-treated for up to 16 additional weeks. Patients who experienced partial clearance during the initial treatment period entered an extended treatment period of up to an additional 16 weeks. A total of 943 patients from 114 clinic sites in 20 countries participated in this study. Complete clinical clearance was observed in 451/943 (47.8%) patients (intent-to-treat (ITT) analysis) during the initial treatment period, with clearance in an additional 52 (5.5%) patients during the extended treatment period beyond 16 weeks. The overall clearance rate for the combined treatment periods was 53.3%. In a treatment failure analysis, the overall clearance rate was 65.5%; a greater proportion of female patients (75.5%) experienced complete clearance than male patients (56.9%). Low recurrence rates, of 8.8% and 23.0%, were observed at the end of the 3- and 6-month follow-up periods, respectively. The sustained clearance rates (patients who cleared during treatment and remained clear at the end of the follow-up period) after 3 and 6 months were 41.6% and 33.0% (ITT analysis), respectively. Local erythema occurred in 67% of patients. In the majority of patients local skin reactions were of mild to moderate severity. In conclusion, imiquimod 5% cream is an effective self-applied treatment for external genital/perianal warts when applied for up to 16 weeks and is well tolerated for up to 32 weeks.

Treatment of anogenital warts.
The treatment of anogenital warts has long been unsatisfactory, with high treatment failure rates and relapse rates. It would seem that a good cell-mediated immune response is important for successful treatment, and the development of immune response modifiers such as Imiquimod give hope for an improved outcome for many patients.

An international survey of patients with genital warts: perceptions regarding treatment and impact on lifestyle.
Our aim was to determine country-specific attitudes and perceptions of patients with genital warts and to understand the psychosexual impact of the disease and its treatment. We used a standardized discussion guide to interview patients with genital warts in Canada, France, Germany, the UK, and the USA about their perceptions and concerns regarding the diagnosis, treatment, and psychosexual impact of the disease. Interviews were conducted in person and lasted approximately 30 min. The study group included 80 men and 86 women with genital warts. Forty-seven per cent were currently undergoing treatment. Overall, 49% of the men had first consulted a general or family practitioner, and 52% of the women had first consulted a gynaecologist. Although all the patients eventually consulted a physician about their warts, one-third delayed seeing a doctor because they thought the condition would resolve on its own or that the problem was not serious. Most patients reported that treatment was associated with pain, discomfort, and embarrassment. Sixty per cent of patients experienced a recurrence after initial clearance with treatment. More than 80% stated that they had had little or no involvement in the selection of treatment. Globally, 52% of men and 61% of women were 'quite concerned' or 'very concerned' about having genital warts, although there were significant variations by country. Approximately two-thirds of patients had made lifestyle changes regarding sexual relationships. In addition, two-thirds believed that there were risks associated with having genital warts; the most common risk identified was a link to cancer (cervical and unspecified). A high level of anxiety is associated with the diagnosis and treatment of genital warts. Patients with genital warts require understanding and an acknowledgement of their concerns. A better understanding of the psychosexual aspect of the disease by health-care providers is pivotal to effective disease management and patient counselling.

The molecular epidemiology of human immunodeficiency virus type 1 in six cities in Britain and Ireland.
We have sequenced the p17 coding regions of the gag gene from 211 patients infected either through injecting drug use (IDU) or by sexual intercourse between men from six cities in Scotland, N. England, N. Ireland, and the Republic of Ireland. All sequences were of subtype B. Phylogenetic analysis revealed substantial heterogeneity in the sequences from homosexual men. In contrast, sequence from over 80% of IDUs formed a relatively tight cluster, distinct both from those of published isolates and of the gay men. There was no large-scale clustering of sequences by city in either risk group, although a number of close associations between pairs of individuals were observed. From the known date of the HIV-1 epidemic among IDUs in Edinburgh, the rate of sequence divergence at synonymous sites is estimated to be about 0.8%. On this basis we estimate the date of divergence of the sequences among homosexual men to be about 1975, which may correspond to the origin of the B subtype epidemic.

A pilot study to investigate the treatment of anogenital warts with Topical Lithium Succinate cream (8% lithium succinate, 0.05% zinc sulphate).
The incidence of anogenital warts (condyloma acuminatum) is rapidly increasing while there is still no totally satisfactory treatment available. In light of the emphasis of experimental approaches toward the prevention of viral replication and evidence of the antiviral action of lithium salts it was proposed to investigate the efficacy of Topical Lithium Succinate cream (LSC) in the treatment of anogenital warts. A total of 101 patients (42 women, 59 men) were randomized to receive either active or placebo treatment for a period of 4 weeks. Assessment of the number, location, size and area of coverage of the warts was made by the clinician at baseline, weeks 2, 4, 6 and 12. Compliance to the study protocol following cessation of treatment at week 4 was extremely poor. The high drop-out rate after this was felt to invalidate data collected after that point. It was therefore decided that the analysis should concentrate on the treatment period. Of 101 patients entering the trial 51 received active (30 male and 21 female) and 50 received placebo (29 male, 21 female). The primary efficacy variable was percentage change from baseline in the overall coverage of lesions. Over all patients LSC treatment resulted in a reduction of 42% (P<0.02) in the overall coverage of lesions. Separate analyses for male and female patients showed that for males there was a highly significant reduction in the coverage of lesions of 65% (P<0.02). However for females the reduction of 11% was not significant. A possible explanation for this difference between the sexes is that as many of the lesions in the female patients were internal therefore this could lead to difficulty in both application of the cream, and subsequent lesion assessment.

The Unlinked Anonymous HIV Prevalence Monitoring Programme in N. Ireland 1992-1995.
Previous evidence has suggested that Northern Ireland is a low seroprevalence area for HIV infection. The Unlinked Anonymous HIV Prevalence Monitoring Programme initiated in England and Wales in 1990 was extended to Northern Ireland in 1992. Patients attending the Genitourinary Medicine Clinic at the Royal Victoria Hospital have, with informed consent, been tested anonymously for HIV infection since that time. The results of the survey between 1992 and 1995 have shown an overall seroprevalence rate 3.01% for homosexual/bisexual men, 0.08% for heterosexual men, and 0.05% for heterosexual women. These results confirm the previous impression of low HIV seroprevalence in Northern Ireland and the survey provides an excellent longitudinal study by which changes may be monitored.

Combined therapy trial with interferon alpha-2a and ablative therapy in the treatment of anogenital warts.
OBJECTIVE: To determine whether the combination of systemically administered interferon alpha-2a and ablative surgery for the treatment of genital and/or perianal warts produces a 30% or greater improvement in lasting response rate compared with a control group receiving a combination of placebo and ablative therapy. DESIGN: Randomised, triple-blind, placebo-controlled trial using 1 or 3 MIU of interferon alpha-2a or placebo administered subcutaneously three times weekly for 10 weeks in combination with ablative surgery. SETTING: International, multicentre study in 10 genitourinary medicine clinics. PATIENTS: Two hundred and fifty patients with anogenital warts. MAIN OUTCOME MEASURES: Lasting response at week 38. RESULTS: Standard efficacy analysis at week 38 showed a lasting response in 51% (35/68) of 3 MIU interferon-treated patients, 48% (30/63) of 1 MIU interferon-treated patients and 43% (29/67) of placebo-treated patients. CONCLUSIONS: With the doses and regime described, treatment with interferon alpha-2a in combination with ablative therapy is not significantly superior in the treatment of anogenital warts than placebo and ablative therapy.

Detection of human papilloma virus DNA sequences in oral squamous cell papillomas by the polymerase chain reaction.
Nineteen clinically diagnosed, and histologically confirmed oral squamous cell papillomas were analyzed for the presence of human papilloma virus DNA sequence by the highly sensitive polymerase chain reaction technique, followed by dot blot hybridization of the polymerase chain reaction product with digoxigenin-labeled, type-specific oligonucleotide probes for human papilloma virus DNA types 6, 11, 16, and 18. Human papilloma virus DNA types 6 and 11 were identified in 68% of these oral lesions, which raises the possibility of an etiologic role for human papilloma virus in the pathogenesis of oral squamous cell papillomas.

A survey of the use of prostitutes (commercial sex workers) by new male attenders at a genito urinary medicine clinic.
This study documents the use of prostitutes (commercial sex workers) by new male patients attending a genito urinary medicine clinic. 541 consecutive male patients completed an anonymous self-administered questionnaire. 48 (8.9%) gave a history of previous purchase of sexual services in Northern Ireland and/or elsewhere; 69% of these encounters occurred outside Northern Ireland. The largest group were single men aged 20-29 years. 87% of those who purchased services in Northern Ireland were asked by the prostitute to use a condom compared with 60% elsewhere, but there was no significant difference in actual condom use between both groups (66.7% vs 72.7%) Only 21% of patients who had purchased the services more than once used condoms consistently and 29% were willing to pay more for unprotected sexual intercourse. 40% attributed their attendance at this clinic directly or indirectly to their encounter with a prostitute. Encounters with prostitutes were often related to alcohol consumption, 88% sometimes or always purchasing these services after drinking alcohol. Despite widespread publicity at-risk behaviour involving unprotected sexual intercourse with prostitutes is not uncommon. Health education should be targeted at the young single male who travels outside Northern Ireland.

A randomised, double-blind, parallel group study to compare subcutaneous interferon alpha-2a plus podophyllin with placebo plus podophyllin in the treatment of primary condylomata acuminata.
OBJECTIVES: The primary objective was to determine if six weeks treatment with subcutaneous interferon alpha-2a (IFN) and podophyllin 25% W/V administered twice per week, preceded by IFN alpha-2a three times weekly for one week showed a greater complete response rate in patients with primary condylomata acuminata when assessed at week 10 than treatment with podophyllin and placebo injections in the same schedule. The secondary objective was to compare recurrence rates in complete responders at six months in the two treatment groups. DESIGN: Randomised, double-blind parallel group study. SETTING: Multicentre study in six genitourinary clinics within the U.K. PATIENTS: One hundred and twenty-four patients with primary anogenital warts. MAIN OUTCOME MEASURES: Complete response rate at week 10, and recurrence rate at week 26 in complete responders. RESULTS: At week 10 analysis of the efficacy population showed complete response in 36% (15/42 patients) of IFN-treated group and 26% (11/43 patients) in the placebo group (no significant difference). Analysis of the safety population at week 26 showed persistence of the complete response in 57% (8/14 patients) of the IFN-treated group and 80% (12/15 patients) of the placebo group (no significant difference). Adverse effects were more common in IFN-treated patients, involved particularly application site reaction and malaise but were generally mild. CONCLUSIONS: At the dose and with the regime described treatment with IFN alpha-2a in combination with podophyllin is no more effective in the treatment of primary anogenital warts than podophyllin alone and is associated with more adverse events.

Association of Chlamydia trachomatis with tubal infertility.
A study was undertaken to determine whether the positive correlation between Chlamydia trachomatis antibodies and tubal infertility, noted by workers in other countries, also applied to infertile women in Northern Ireland. Ninety-one infertile women and 106 fertile controls were tested for current cervical infection with C. trachomatis and for evidence of past chlamydial infection. The incidence of C. trachomatis infection of the cervix was 5.8% in the infertile group and 2.8% in the control group. The prevalence of C. trachomatis antibody was 22% in the infertile group and 18.9% in the control group. Previous termination of pregnancy, history of sexually transmitted disease and number of sexual partners were identified as risk factors for seropositivity and tubal disease. We concluded that it would be of value to screen women attending the infertility clinic for C. trachomatis infection of the cervix, and that testing these patients for chlamydia antibodies may also be useful in planning further investigation.
