Burden of genital warts in Colombia: an observational study / Carga das verrugas genitais na Colômbia: um estudo observacional

Introduction: Genital warts are benign lesions caused by sexual transmission of human papillomavirus types 6 and 11, with significant impact on healthcare resource use and patients' quality of life. Objective: To describe the epidemiology of genital warts in adults visiting a physician office for any reason, physician practice patterns, and healthcare resource use and costs in Colombia. Methods: Participants were a convenience sample of 53 physicians in 5 specialties: primary care (15), gynecology (24), urology (12), proctology (1), and dermatology (1). Physicians completed a survey and daily log of all patients 18-60 years old seen over 10 days in their practices in 2016-2017. The physician survey recorded genital warts consultation and management patterns. The daily log recorded patient demographic information and genital warts diagnosis. Results: Among 6,393 patients logged by physicians, the genital warts prevalence was 2.03% (95%CI 1.69­2.38) and incidence 1.30% (95%CI 1.02­1.58). Primary care physicians referred most of their genital warts cases for treatment (female: mean 63.3%, SD=44.8; male: mean 58.3%, SD=43.8). Treatment of non-resistant episodes (<6-month duration) lasted an average of 37.4 days (SD=29.4) and required an average of 4.0 (SD=1.9) office visits for females and 3.0 (SD=1.7) for males. The overall mean cost of an episode of care was USD558.13 (SD=507.30). Conclusion: Genital warts cases reported by most participant physicians were mainly direct-consult, but patients were typically treated by specialists. Much of the genital warts health care utilization and costs reported could be prevented by immunization with the quadrivalent or nonavalent HPV vaccine.

Introdução: As verrugas genitais são lesões benignas, de transmissão sexual, causadas pelo papilomavírus humano tipos 6 e 11 e que causam impacto significativo no uso de recursos de saúde e na qualidade de vida dos pacientes. Objetivo: Descrever a epidemiologia das verrugas genitais em adultos que buscaram atendimento médico ambulatorial por qualquer motivo, incluindo padrões de prática médica, uso de recursos de saúde e custos na Colômbia. Métodos: foi utilizada uma amostra de conveniência composta por 53 médicos em 5 especialidades: clínico geral (15), ginecologia (24), urologia (12), proctologia (1) e dermatologia (1). Os médicos completaram um questionário e registros diários de todos os pacientes com idade entre 18 e 60 anos atendidos durante 10 dias em seus consultórios em 2016-2017. O questionário registrou os padrões de prática médica e de tratamento de verrugas genitais. Os registros diários continham informações demográficas do paciente e o diagnóstico de verrugas genitais. Resultados: Entre 6.393 atendimentos médicos, a prevalência das verrugas genitais foi de 2,03% (IC95% 1,69­2,38) e a incidência de 1,30% (IC95% 1,02­1,58). Os clínicos gerais encaminharam a maioria dos pacientes com verrugas genitais para tratamento (mulheres: média de 63,3%, DP=44,8; homens: média de 58,3%, DP=43,8). O tratamento dos casos não-persistentes (<6 meses de duração) durou em média 37,4 dias (DP=29,4) e requereu uma média de 4,0 (DP=1,9) consultas para mulheres e 3,0 (DP=1,7) para homens. O custo médio geral do tratamento foi de US$ 558,13 (SD=507,30). Conclusão: Os casos de verrugas genitais relatados pela maioria dos médicos participantes derivaram-se principalmente de atendimentos primários e os pacientes foram tratados geralmente por especialistas. Grande parte da utilização de recursos e custos relacionados a verrugas genitais poderia ser evitada pela imunização com a vacina papilomavírus humano 4-valente ou 9-valente.

Incidence, psychosocial burden, and economic impact of genital warts in Mexico / Incidencia, carga psicosocial e impacto económico de las verrugas genitales en México

Abstract: Objective: To estimate the burden of genital warts (GW) in Mexico. Materials and methods: We estimated the annual incidence of GW based on data reported by specialist physicians. We also assessed GW treatment practices, the average cost of treatment, and the psychosocial burden of GW among patients. Results: The annual incidence of GW in Mexico was estimated to be 547 200 cases. Treatment procedures vary by specialist and patient gender. The estimated annual cost was $195 million USD. The psychosocial impact of GW was slightly greater in males than females. Conclusions: This is the first evaluation of the burden of GW in Mexico. Our data suggest that GW are common, with significant health-related costs and psychosocial impact.

Comparison of the Natural History of Genital HPV Infection among Men by Country: Brazil, Mexico, and the United States.

Background: Male genital human papillomavirus (HPV) prevalence and incidence has been reported to vary by geographical location. Our objective was to assess the natural history of genital HPV by country among men with a median of 48 months of follow-up.Methods: Men ages 18-70 years were recruited from United States (n = 1,326), Mexico (n = 1,349), and Brazil (n = 1,410). Genital specimens were collected every 6 months and HPV genotyping identified 37 HPV genotypes. Prevalence of HPV was compared between the three countries using the Fisher exact test. Incidence rates and 95% confidence intervals were calculated. The median time to HPV clearance among men with an incident infection was estimated using the Kaplan-Meier method.Results: The prevalence and incidence of the genital HPV types known to cause disease in males (HPV 16 and 6) was significantly higher among men from Brazil than men from Mexico. Prevalence and incidence of those genital HPV types in the United States varied between being comparable with those of Mexico or Brazil. Although genital HPV16 duration was significantly longer in Brazil (P = 0.04) compared with Mexico and the United States, HPV6 duration was shortest in Brazil (P = 0.03) compared with Mexico and the United States.Conclusions: Men in Brazil and Mexico often have similar, if not higher prevalence of HPV compared with men from the United States.Impact: Currently, there is no routine screening for genital HPV among males and while HPV is common in men, and most naturally clear the infection, a proportion of men do develop HPV-related diseases. Men may benefit from gender-neutral vaccine policies. Cancer Epidemiol Biomarkers Prev; 26(7); 1043-52. ©2017 AACR.

Etiology of Genital Ulcer Disease in Male Patients Attending a Sexually Transmitted Diseases Clinic: First Assessment in Cuba.

BACKGROUND: Sexually transmitted diseases (STDs) and in particular genital ulcer disease (GUD) have a major impact on morbidity and mortality in developing countries. The World Health Organization recommends the use of syndromic guidelines for the treatment of sexually transmitted infections (STIs) in resource-constrained countries. Surveillance of autochthonous etiologies provides epidemiological information contributing to the prevention and treatment of STIs. We investigated the etiology and factors associated with GUD among male patients attending a STD clinic in Havana, Cuba. METHODS: Swabs from genital ulcers of 113 male patients, collected from May 2012 to June 2015, were analyzed using PCR for herpes simplex virus types 1 and 2, Treponema pallidum, Haemophilus ducreyi, and Chlamydia trachomatis. We also investigated the clinical and epidemiological characteristics associated with the presence of these pathogens in GUD. RESULTS: At least one of the pathogens was detected in 70% of patients. The occurrence of the pathogens was herpes simplex virus type 2 (HSV-2) (51.3%), T. pallidum (29.2%), and C. trachomatis (1.8%). Co-infections occurred as follows: T. pallidum-HSV-2 (10.6%), C. trachomatis-HSV-2 (0.9%) and C. trachomatis-T. pallidum (0.9%). Herpes simplex virus type 1 and H. ducreyi were not detected. Ages 15 to 40 years, HIV-positive serostatus, and no condom use were significant risk factors for the presence of HSV-2 in genital ulcers. CONCLUSIONS: Our preliminary results highlight the predominance of HSV-2 and T. pallidum as the leading GUD etiologies in the study population and identified risk factors associated with HSV-2. This information should help to inform guidelines for better management of GUD in Havana, Cuba.

Urologic disease in a resource-poor country.

BACKGROUND: Understanding the role that urologic disease plays within central Haiti could lead to the development of sustainable and regionally appropriate urologic care. We aim to document the prevalence of urologic surgical disease presenting for treatment in central Haiti. METHODS: The present study is based on a retrospective review of surgical case logs at five Partners in Health and Zanmi Lasante hospitals in central Haiti. Data were collected from June 30, 2009, through July 29, 2010, and included patient demographics, disease processes, interventions required, surgeon name, and surgeon training (urologic trained versus non-urologic trained). RESULTS: Urologic surgical disease comprised 498/5,539 (9.0 %) of all surgical cases in central Haiti from July 2009-July 2010. A total of 492 diagnoses and 498 urologic procedures on 469 patients were recorded. Most common diagnoses included hydrocele (33.3 %), phimosis (23.0 %), benign prostatic hyperplasia (10.8 %), and cryptorchidism (7.3 %). Hydrocelectomy was the most commonly performed procedure (160/498, 32.1 %), followed by circumcision (117/498, 23.4 %) and open prostatectomy (38/498, 7.6 %). Surgeon training (urologic versus non-urologic) was determined for 360/498 (72.3 %) of surgical cases. Urologic trained surgeons performed 55/360 (15.3 %) of all surgical procedures. Among patients who underwent prostatectomy, urology surgeons performed 14/31 (45.2 %) of open prostatectomies, and non-urology surgeons performed 17/31 (54.8 %). Urologists performed all transurethral resections of the prostate (9 vs. 0; p = 0.0051). CONCLUSIONS: Urologic surgical diseases comprise a substantial source of morbidity for patients in central Haiti. Understanding the scale and scope of urologic disease is important in developing health systems to adequately address the regional burden of surgical disease in limited-resource settings.

Population based study of genital Chlamydia trachomatis prevalence and associated factors in Norway: a cross sectional study.

BACKGROUND: The number of diagnosed cases of Chlamydia trachomatis infection has been increasing in the past years in Norway although the testing rate has been relatively stable. The aim of this study was to measure the prevalence of genital Chlamydia trachomatis in young men and women in one county in Norway and determine associated factors in order to better target preventive measures. METHODS: We mailed to a random sample of 10,000 persons aged 18-25 in Rogaland county a mail-back urine sample kit and a self-administered questionnaire with questions on socio-demographic details, health seeking behaviour and symptoms of and history of sexually transmitted diseases. Associations between current Clamydia trachomatis infection and the above mentioned factors were studied by multiple logistic regression. RESULTS: The response rate among women was 18.9% (930/4923) and 11.9% (605/5077) among men. The prevalence of Chlamydia trachomatis infection was 5.8% (95% CI 4.5-6.8) among women and 5.1% (95% CI 3.8-6.8) among men. For men a greater number of partners during the last year (p for trend < 0.001), and living in a municipality without a local youth clinic increased the odds of infection (OR 8.6, 95% CI 2.2-33.9). For women a greater number of partners during the last year (p < 0.001) and not having consulted a family doctor for STIs (OR 2.1 95% CI 1.1-4.2) were positively associated with infection while not having a previous Chlamydia trachomatis diagnosis decreased the odds of having this infection (OR 0.3, 95% CI 0.2-0.7). CONCLUSION: Our results indicate the importance of having a visible youth clinic in each municipality. It also suggests targeting women who have had a previous Chlamydia trachomatis infection diagnosed before.

Reproductive tract complications associated with Chlamydia trachomatis infection in US Air Force males within 4 years of testing.

BACKGROUND: Chlamydia trachomatis (CT) is a common sexually transmitted infection for which young, sexually active persons are at highest risk. Health consequences such as orchitis/epididymitis, prostatitis, infertility, and urethral stricture have been described among CT-infected males, although not all of these are indisputably linked to CT. Current literature lacks population-based studies needed to examine these associations on a larger scale, to evaluate the true risk of developing complications after a CT infection. The US Air Force contains a large population of young, sexually active males, making it suitable for conducting such a study. METHODS: We conducted a retrospective cohort study between 2001 and 2005 comparing the incidence of orchitis/epididymitis, prostatitis, infertility, and urethral stricture among male Air Force members with and without prior CT infections. Cumulative incidence rates were calculated and Cox proportional hazard models were generated to evaluate the risk of developing complications and to adjust for potential confounders. RESULTS: Among 17,764 men enrolled in the study, 913 (5.14%) experienced a reproductive tract outcome. Among CT-positive men, cumulative incidences of orchitis/epididymitis, prostatitis, infertility, and urethral stricture were 4.28%, 1.41%, 1.27%, and 0.13%, respectively. Orchitis/epididymitis [Hazard ratio (HR) = 1.38 (1.13-1.70)] and "any" outcome [HR = 1.37 (1.16-1.61)] were positively associated with CT; infertility was marginally associated [HR = 1.36 (0.93-2.00)]. CONCLUSIONS: Overall, the burden of reproductive health outcomes among Air Force males is small. Significant associations were observed between CT and both orchitis/epididymitis and any outcome; a larger cohort or longer follow-up may have detected a significant association between CT and infertility.

Sexually transmitted diseases and HIV/AIDS in Vanuatu: a cause for concern and action.

AIMS: This article argues that sexually transmitted infections (STIs) and HIV/AIDS in Vanuatu are a cause for concern and that a strong response is needed to stem an epidemic. METHODS: Three sources of data are used: studies and policy documents on STIs and HIV/AIDS in Vanuatu; analysis of reported STI cases from public health facilities; and key informant interviews with 14 policy stakeholders. RESULTS: In Port Vila (capital of Vanuatu), more than a quarter of the women attending antenatal clinics were positive for at least one STI. Although Vanuatu Ministry of Health (MoH) case records for gonorrhoea, genital ulceration, and syphilis show national prevalence rates have remained relatively constant between 1.2% and 2%, there is probably gross under-reporting because MoH data exclude trichomoniasis and chlamydiasis cases; surveillance systems are poor; and patient access to services is limited. High STI prevalence and several socioeconomic factors create a high-risk environment for the rapid spread of HIV/AIDS. DISCUSSION: The need for a strategic response in Vanuatu is pressing. Priorities for action include the scaling up of awareness programmes for young people, particularly girls, and the development of surveillance systems. Government capacity weaknesses mean the MoH should explore possible partnerships with the non-government organisation (NGO) sector and point to the need for international support to implement a new government Strategic Plan.

The clinical and economic consequences of screening young men for genital chlamydial infection.

BACKGROUND: Wide-scale application of urine-based screening of asymptomatic men for chlamydial infection has not been thoroughly assessed. GOAL: The goal was to compare clinical and economic consequences of three strategies: (1). no screening, (2). screening with ligase chain reaction (LCR) assay of urine, and (3). prescreening urine with a leukocyte esterase test (LE) and confirming positives with LCR. STUDY DESIGN: We used a decision analytic model. RESULTS: At a chlamydia prevalence of 5%, the no screening cost was US dollars 7.44 per man screened, resulting in 522 cases of pelvic inflammatory disease (PID) per 100000 men. LE-LCR was most cost-effective, preventing 242 cases of PID over no screening at an additional cost of US dollars 29.14 per male screened. The LCR strategy prevented 104 more cases of PID than LE-LCR but cost US dollars 22.62 more per male screened. For this to be more efficient than LE-LCR, the LCR assay cost needed to decline to

The epidemiology and treatment of anogenital warts in Singapore: a retrospective evaluation.

INTRODUCTION: A retrospective study in the referral centre for sexually transmitted infections (STIs) in Singapore to describe the epidemiology and treatment outcome of patients with anogenital warts. SUBJECTS AND METHODS: We reviewed the case records of 301 patients with anogenital warts who were seen over a 1-year period (1999). We also attempted to interview every patient by telephone to find out if they had any clinical recurrences for which treatment was sought elsewhere. RESULTS: There were 255 males and 46 females with a mean age of 34 years. Two hundred and nineteen (72.8%) presented with symptoms lasting 12 weeks or less. In males, warts occurred most frequently in the preputial cavity (52.5%) and on the penile shaft (40.8%). In females, they occurred most frequently on the external genitalia (91.3%). Two hundred and thirty-five males were treated with cryotherapy and 69% (95% CI, 62.6% to 74.8%) achieved clinical resolution after a mean of 6 treatment cycles. Seven males were treated with podophyllin 0.25% in ethanol and 71% (95% CI, 29.0% to 96.3%) were clinically cured after a mean of 4 treatment cycles. Thirty-nine females were treated with cryotherapy and 67% (95% CI, 49.8% to 80.9%) achieved clinical cure after a mean of 4 treatment cycles. Of the 290 patients treated at the centre, 212 (73%; 95% CI, 67.3% to 77.8%) patients (184 males, 28 females) achieved clinical cure after a mean of 7 weeks (range, 1 to 34 weeks); 90% (95% CI, 86.0% to 93.2%) of them by 15 weeks. Seven-two patients defaulted follow-up and 6 responded partially to treatment. Of the 212 patients who achieved clinical cure, 195 were interviewed by telephone, on an average, 17.7 months after clinical resolution. Thirty-seven (19%; 95% CI, 13.7% to 25.2%), all males, relapsed clinically after a mean of 100 days (range, 5 to 329 days); 90% (95% CI, 84.6% to 93.6%) relapsed by 228 days. CONCLUSIONS: Podophyllin 0.25% in ethanol was the most cost-effective treatment for males. One in 5 patients had a recurrence of their warts and most had their recurrence within 8 months of initial resolution.

Male reproductive health research needs and research agenda: Asian and Chinese perspective.

Research that addresses male reproductive health should assist in the development of reproductive health programmes and policy; identify and test new leads in male contraceptive technology; establish effective male involvement initiatives which are likely to have a positive impact on the reproductive health of men and women; guide the allocation of health care resources to ensure cost-effectiveness of interventions; generate new knowledge, develop diagnostic technology in reproductive health and offer optimal treatment/care regimens. In considering the needs and demands of male reproductive health research in Asia and the Pacific, the following six research topics are recommended as the priority research areas: male contraceptive technology; male reproductive health behaviour and male adolescent reproductive health; male reproductive aging including male menopause and other diseases; male RTIs, STDs, HIV/AIDS; prevalence, management and prevention of male infertility; environment and semen quality and other male reproductive problems. One of the major challenges now facing us is the elaboration of a comprehensive, yet realistic male reproductive health research agenda that reflect the needs and demands of Asian developing countries. To this end, to make use of an interdisciplinary approach is of strategic importance. The most creative insights and productive leads are likely to emerge from a research team that is interdisciplinary especially in the field of reproductive health.

Evaluation of acute scrotum in the emergency department.

A 2-year retrospective review of 238 cases of acute scrotal pain encountered in a children's hospital emergency department is presented. The incidences of testicular torsion, torsion of a testicular appendage, and epididymitis were 16%, 46%, and 35%, respectively. Testicular salvage was critically dependent on the interval between onset of pain and surgical intervention. No testis likely to have been viable at the time of presentation was "lost." The diagnostic error rate on first encounter was 7%, resulting in 10 negative scrotal explorations. With the exception of cases of far-advanced necrotic testes, both color Doppler ultrasound and radioisotope imaging were highly specific diagnostic modalities. Thirty-nine percent of the children with epididymitis who underwent investigation were found to have either structural or functional urinary tract abnormalities. Noninvasive urodynamic studies appear to be useful screening modalities in older children with epididymitis.

Assessment of ram fertility in hill flocks in Argyll.

Examination of 1260 rams, involving 1540 semen examinations, revealed that 9 per cent of rams in hill flocks in Argyll were subfertile as assessed by semen evaluation. Although 34 lesions of the genitalia were identified, only 13 were associated with poor semen quality. A five year survey of one blackface flock resulted in the elimination, after three years, of a 17 per cent level of infertility following routine examination of all rams, with an increase of 2.27 per cent in the lamb crop. Based on the 1981 lamb prices for this flock an increased income of 1085 pounds was achieved.

Sexually transmitted diseases: extract from the Annual Report of the Chief Medical Officer of the Department of Health and Social Security for the Year 1978.

PIP: In England, a comparison of the number of newly reported cases of sexually transmitted diseases for the years ending June 30, 1977 and 1978 indicated that during the latter year there was an increase in the incidence of early and late syphilis, genital candidosis, genital herpes, simplex, and nonspecific genital infection and a slight decline in the incidence of gonorrhea. During the year ending June 30, 1978, early syphilis increased 5.4% among men and 11.8% among women, and the number of cases/100,000 population was 10.18 for men and 1.91 for women. The reported number of new cases of late syphilis increased 15.8% during that same year, and the number of new cases/100,000 was 4.32 for men 1.90 for women. Gonorrhea cases decreased by 2.5% among men and by 3.3% among women, and the number of new cases/100,000 was 160.55 for men and 89.23 for women. The number of new cases of chancroid increased slightly, and there were 0.11 cases /100,000 population. Nonspecific genital infections increased for the total population by 2.2%; however, the rate among women declined by 2.1% and among men increased by 3.4%. The number of new cases of herpes simplex/100,000 population was 22.50 for men and 12.25 for women. 4 tables provided information on 1) the number of new reported cases for the years ending in June 30, 1977 and 1978 and the incidence rates for 1974-78 for syphilis, gonorrhea, and chancroid and 2) incidence rates for the years ending on June 1974-78 for other sexually transmitted diseases. During the year ending June 30, 1978, a total of 518,839 persons, representing a 2% increase over the previous year, presented at hospital clinics for venereal disease checkups. 5% of these individuals were noninfected. During 1978, progress was made in training more workers and expanding facilities for tracing individuals who had contact with persons known to have venereal disease. In addition, the genitourinary medical staff at facilities in England and Wales increased from 203-211 between 1977-78. 101 of these staff members were consultants. Consultants, according to the Special Advisory Committee in Genitourinary Medicine of the Royal College of Physicians should be members of the Royal College of Physicians and have 4 years of training at the senior registrar level. This requirement has been relaxed somewhat, however, due to recruitment difficulties. Requirement of male nurses is still inadedquate. In regard to progress in education and training personnel to work in the venereal disease area, a Department of Genitourinary Medicine is being established at the Middlesex Hospital Medical School of London University. British physicians played an active role in several international conferences on sexually transmitted diseases in 1978, and the Department of Health and Social Security continued to provide funds for health professionals to visit veneral disease centers in other countries in order to learn about new techniques for diagnosing and treating veneral disease.^ieng
