This comparative survey of college health providers explored nurse practitioners' (N = 73) and physicians' (N = 70) knowledge, attitudes, and management practices related to genital human papillomavirus (HPV) infection in females. Both groups had adequate knowledge of basic issues of HPV epidemiology, diagnosis, and treatment. Divergent attitudes and management practices were reported among the providers, with generally low agreement with national STD treatment guidelines published by the Centers for Disease Control and Prevention (CDC). Generally, providers tended to practice a more aggressive management approach on several aspects of HPV infection than recommended by the CDC guidelines. The one major exception reported by the majority of providers was the conservative use of colposcopy for identifying subclinical HPV infection in patients with external genital warts, a finding consistent with CDC guidelines. The availability of colposcopy within a provider's health center was found to be associated with the reported use of colposcopy. Recommendation for future research and implications for college health and advanced nursing practice are addressed.

This study was carried out to assess the management by general practitioners of patients with genital warts. An anonymized postal questionnaire was sent to 2060 general practitioners in the north west of England; 1260 (61.2%) completed questionnaires were returned. A total of 76.69% of GPs saw one or more cases per quarter. Of 468 (37.1%) GPs who managed patients in-house, 393 (83.9%) used podophyllin of concentration between 0.5 and 50%; 169 (43%) did not specify the podophyllin concentration and 112(23.9%) used podophyllotoxin. Of 395 GPs (31.3%) prescribing patient self-treatment, 259 (65.6%) prescribed podophyllin, but 60.23% did not specify the concentration; 134(33.9%) prescribed podophyllotoxin. Screening for selected sexually transmitted infections (STIs) was performed by 258/618 (41.7%) GPs. Only 74 (11.97%) screened for Chlamydia trachomatis and Neisseria gonorrhoeae and Trichomonas vaginalis. Partner notification was advised by 1138 (90.3%) and condom use by 1027 (81.5%). Only 333 (26.4%) referred all patients to GUM departments. Many GPs manage patients in-house, most using podophyllin solutions which vary in concentration, are non-standardized and potentially hazardous. Most GPs who instigate patient self-treatment prescribe podophyllin which is not licensed for this usage. Podophyllotoxin 0.5% is a safe, effective alternative. Few non-referring GPs screened for the 3 common STIs, thus putting patients at risk of complications such as pelvic inflammatory disease. Non-referral of patients with genital warts to GUM departments may have costly medical and financial consequences.

An initial audit of the treatment of patients presenting to the GUM Department at Leeds General Infirmary with a first episode of anogenital warts was reported in 1993. Treatment was found to be unselective and poorly monitored and the results of treatment were disappointing. As a consequence, guidelines for the management of new patients presenting with genital warts were devised. In order to establish whether these guidelines had produced any improvements in outcome, a second audit was performed looking at the results of treatment in patients with new genital warts who attended 6 months or more after the new guidelines were introduced. Progress was documented for 6 months after presentation. There was a significant fall in the numbers of patients receiving podophyllin 25% solution as first-line treatment, and corresponding increases in the initial use of cryotherapy, trichloracetic acid and, in men, podophyllotoxin solution. (Podophyllotoxin was not licensed for use in women at the time of the second audit.) There were significant improvements in the outcome of treatment. Originally 44% of men had warts despite receiving treatment for 3 months, and 32% were still attending for treatment 6 months after presentation. After the introduction of treatment guidelines, these figures had fallen to 8% and 3% respectively. In the first audit 38% of women still had warts after 3 months' treatment but in the second audit this figure was reduced to 18%. At 6 months, the percentage of women still attending for treatment was halved from 12% in the first audit to 6% in the second audit. The mean number of clinic visits fell from 5 to 3 in men and from 9 to 6 in women. The treatment protocols have been modified and now include the use of podophyllotoxin cream and solution in both men and women.

Podophyllotoxin solution (0.5%) is licensed for use in the treatment of condylomata acuminata (genital warts) in men in a number of European countries. In some countries, approval also extends to treatment of genital warts in women. This controlled randomized prospective study evaluated the efficacy and safety of a cream formulation of podophyllotoxin at 2 concentrations (0.15% and 0.3%), using 0.5% podophyllotoxin solution as a reference treatment. Two separate studies were initiated, to assess the 3 treatment groups in (a) male patients, and (b) female patients. Statistical evaluation was based on a "response rate' calculated at each clinic visit. The mean "response rates' in the male patient study at 4 weeks were 75.1%, 79.0% and 85.6% in the 0.15% cream, 0.3% cream and 0.5% solution groups, respectively. The corresponding "response rates' for the female patient study were 86.2%, 92.6%, and 93.1%, respectively. The relapse rates for both male and female patients were 6.0% in the 0.15% cream group, 8.6% in the 0.3% cream group and 8.6% in the 0.5% solution group. The results show that there were no statistically significant differences between the 3 treatments with regard to both efficacy and safety. This was true for both the male and female patient groups.

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.

To assess the efficacy of a novel glycosylated mammalian cell derived recombinant human interferon-beta (r-hIFN-beta-1a) in the intralesional treatment of genital condylomata acuminata. The study was randomized, double-blind and placebo-controlled. Patients (n=60) with up to 8 distinct condylomata acuminata were randomized to receive either one million international units (IU) of r-hIFN-beta-1a or placebo intralesionally into each lesion, 3 times a week, for a total of 9 occasions. Biopsies were taken from each patient before enrolment to allow human papillomavirus (HPV) testing, and patients were tested for the development of anti-IFN-beta antibodies. Efficacy was assessed by measuring the complete response rate 3 months after treatment. The complete response rate was not significantly better with r-hIFN-beta-1a than with placebo. However, after 3 months, 73.3% of patients treated with r-hIFN-beta-1a had experienced at least a partial response to treatment, compared with 33.3% of placebo-treated patients. At 19 days and 6 weeks, r-hIFN-beta-1a produced a significantly larger reduction in the area of condylomata. Lesions with detectable HPV6 or 11 showed a trend towards a better response rate to treatment with r-hIFN-beta-1a than lesions where no HPV DNA was detected. The treatment was well tolerated. In the 5 patients who developed non-neutralizing anti-IFN-beta antibodies, therapeutic efficacy was not compromised. Intralesional r-hIFN-beta-1a was effective in the reduction of the size of genital condylomata acuminata.

The number of clinic consultations for condylomata acuminata (genital warts) has increased substantially during the last 30 years. Most infections produce benign lesions but a few types may be associated with cervical and penile cancers. Interferons (IFN) have shown antiviral properties to these infections and IFN-beta in particular has demonstrated a specific cytopathic effect in humans. A total of 124 patients with condylomata acuminata, the majority of whom had failed previous therapy, were treated intralesionally with either recombinant human interferon-beta la (r-hIFN-beta-1a) or placebo. Up to 6 lesions were treated in each patient, and injections were made 3 times per week for a total of 9 injections. The patients were then followed up for 3 months. Efficacy assessments at all time points (day 19, week 6 and month 3) showed a clear advantage for the r-hIFN-beta-1a interferon-beta treatment. Patients receiving r-hIFN-beta-1a showed a greater proportion of treatment success in terms of the complete or partial reduction (at least 50%) of the total area of the treated lesions. The treatment was also well tolerated. Headache, flu-like symptoms and asthenia were more common in patients receiving r-hIFN-beta-1a, but these adverse events were generally mild in severity and rarely led to patient withdrawal. It was concluded that r-hIFN-beta-1a has good efficacy in condylomata acuminata, and therefore presents a useful therapeutic alternative in this hard-to-treat condition.

The efficacy of a single cycle of a new therapy for genital warts, intradermal fluorouracil/epinephrine (5-FU/epi) injectable gel, has been evaluated in 2 large pivotal trials; the objective of this study was to evaluate a second cycle of treatment. Twenty-two patients with total wart areas of 5-447 mm2 were treated with up to 2 cycles of < or =6 treatments of 5-FU/epi gel. After the first cycle of treatments, patients with warts showing a partial response or no response or new warts were continued into a second cycle. Seventy-three per cent (16/22) of patients had complete responses. Patients with total wart areas < or = 100 mm2 tended to respond completely in the first cycle of treatment (average 4.7 treatments). Patients with numerous warts or large total wart areas (>100 mm2) required an average of 7.5 treatments to achieve a complete response. Thus, a second treatment cycle may be appropriate for difficult-to-treat patients with numerous warts or large total wart areas.

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.

Cryotherapy is regularly used in our clinic for treating genital warts. Nitrous oxide was used as the cryogenic gas. Following a health and safety review it was decided to monitor the nitrous oxide levels in the treatment room under different conditions. The Occupational Exposure Standard for nitrous oxide is 100 parts per million (PPM) (8-h time weighted average) and an indicative short-term exposure limit of 300 PPM (15-min reference period). High levels of gas were detected, especially when the exhaust was not vented to the outside. Venting of the gas to the outside could also present a hazard to adjacent areas. The situation was considered to be unacceptable and carbon dioxide was proposed as an alternative. The Occupational Exposure Standard for carbon dioxide is 5000 PPM (8-h time weighted average) and a short-term limit of 15,000 PPM (15-min reference period). Carbon dioxide levels were found to be within the Occupational Exposure Standard. There is no noticeable difference in the cryogenic efficacy of the 2 gases. Carbon dioxide is, therefore, a safer alternative. It also offers significant savings when compared with nitrous oxide.
