Abstract
Human papillomavirus (HPV) is a common sexually transmitted virus that can cause cervical cancer and other diseases. Dynamic transmission models (DTMs) have been developed to evaluate the health and economic impacts of HPV vaccination. These models typically include many parameters, such as natural history of the disease, transmission, demographic, behavioral, and screening. To ensure the accuracy of DTM projections, it is important to parameterize them with the best available evidence. This study aimed to identify and synthesize data needed to parametrize DTMs on the natural history of HPV infection and related diseases. Parameters describing data of interest were grouped by their anatomical location (genital warts, recurrent respiratory papillomatosis, and cervical, anal, vaginal, vulvar, head and neck, and penile cancers), and natural history (progression, regression, death, cure, recurrence, detection), and were identified through a systematic literature review (SLR) and complementary targeted literature reviews (TLRs). The extracted data were then synthesized by pooling parameter values across publications, and summarized using the range of values across studies reporting each parameter and the median value from the most relevant study. Data were extracted and synthesized from 223 studies identified in the SLR and TLRs. Parameters frequently reported pertained to cervical cancer outcomes, while data for other anatomical locations were less available. The synthesis of the data provides a large volume of parameter values to inform HPV DTMs, such as annual progression rates from cervical intraepithelial neoplasia (CIN) 1 to CIN 2+ (median of highest quality estimate 0.0836), CIN 2 to CIN 3+ (0.0418), carcinoma in situ (CIS) 2 to local cancer+ (0.0396), and regional to distant cancer (0.0474). Our findings suggest that while there is a large body of evidence on cervical cancer, parameter values featured substantial heterogeneity across studies, and further studies are needed to better parametrize the non-cervical components of HPV DTMs.

Abstract
BACKGROUND Genital warts, besides their importance as symptoms of sexually transmitted infections, can also threaten the sexual health of couples. The purpose of this study was to explore the sexual compatibility in women with active genital warts. METHODS A qualitative study with a conventional content analysis approach in Tehran, Iran, from January 2019 to February 2020 was conducted on a purposeful sample of data saturation achieved after interviewing 14 women with genital warts, 2 couples and 3 dermatologists, 1 sexologist and 1 infectious disease specialist. Data were collected through unstructured interviews and analyzed using conventional content analysis approach. RESULTS After data analysis 224 initial codes, 5 main categories "change in the frequency of sexual activity", "changing types of sexual intercourse", "protected sexual intercourse", "concealment of lesions", "focusing on personal hygiene by couples after sexual activity" and finally a central theme of "adaptation to challenges of sexual intercourse" were extracted. CONCLUSIONS This study revealed the perceptions and experiences of women with active genital warts about the process of their sexual adaptation. The main concepts found in this study focus on challenges related to sexual intercourse. It seems that recognizing women's sexual adaptation challenges after getting genital warts may help them take effective and practical measures to improve their sexual compatibility and health.

Abstract
INTRODUCTION Condylomata acuminata (CA) is a sexually transmitted infection with a high prevalence associated with psychosexual morbidity in both men and women of various age. Up to now, treatment modalities yield low clearance and recurrence rate (RR) and are also deemed low quality evidence-wise. Photodynamic therapy (PDT) is a novel and promising therapy to effectively cure and prevent CA recurrence. METHOD This systematic review was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) and registered to the International Prospective Register of Systematic Review (PROSPERO) (CRD42022332760). RESULTS Ten studies were included in this systematic review. A significant value of complete response (CR) ranging from 63-100% in patients with genital warts after receiving several sessions of PDT. A relatively low recurrence rate was seen in all 10 studies, with an RR of less than 17%. Quality assessment of included studies reported mostly high-quality research. CONCLUSIONS PDT therapy resulted in a higher CR with significantly lower RR compared to other therapies. Thus, PDT can be an alternative treatment of CA with low RR and minimal side effects. Additional research, especially randomized clinical trials in various countries, is needed to further substantiate this treatment and formulate definitive protocols.

Abstract
Vulvar vestibular papillomatosis (VP) is considered a normal anatomical variant of the vulva. We present a 19-year-old girl with a history of "small itchy growths" on the vulva for 2 months without any associated discharge. These lesions were causing significant anxiety to the patient. Cutaneous examination revealed multiple, uniformly arranged, skin-colored, monomorphic micropapillae on the inner aspect of the labia minora. Biopsy showed mucosal hyperplasia with papillomatosis and loosely arranged subdermal tissue, no koilocytes were spotted. The diagnosis of vulvar VP was made. We want to highlight this clinical entity as most dermatologists are not familiar with this benign condition and easily confuse it with genital warts. This inexperience may result in unnecessary investigations causing psychological discomfort to the patient. We herein present such a case which brings out the diagnostic dilemma.

Abstract
Background Researchers are interested in genital wart (GW) studies due to their increased incidence. In a single experimental research, virally infected mouse models showed elevated kisspeptin levels and low interferon levels. Objective The objective of the study was to evaluate the serum levels of kisspeptin and interferon (INF)-beta in GW patients. Patients and Methods Forty patients with GWs and forty healthy participants of comparable age and sex as a control group were included in this case-control study. Serum levels of kisspeptin and IFN-beta were measured using ELISA during the period from December 2021 to April 2022. Results Kisspeptin was significantly higher among cases than controls, whereas IFN-beta level was lower among cases than controls (P < 0.001). There were no significant relations between kisspeptin and IFN-beta levels and the clinical data for the studied participants, and there was no significant correlation between both (P > 0.05). Conclusion The reported increased kisspeptin level which was associated with decreased interferon-beta level in patients with GWs might indicate a new insight into viral infection pathogenesis. Further research including all steps in kisspeptin/G protein-coupled receptor 54 pathway is required. Targeted therapy for this pathway may be of value for those patients.

Abstract
Condylomata acuminata is the most common sexually transmitted disease in the world. Physical treatments include excision, cryotherapy, electrocautery and ablative CO2, and Nd:YAG laser ablation, while topical treatments include imiquimod immunotherapy and antimitotic podophyllotoxin or sinecatechins. Efficacies of all methods are low, and recurrences are very common. A new combined method is presented as a single case in a 25-year-old male patient diagnosed with numerous condylomas on the penis, scrotum, and lower abdomen. The treatment consisted of a 7-week topical monotherapy using 5% imiquimod cream followed by local treatment with 20 MHz high-intensity focused ultrasound on remaining recalcitrant lesions. Results showed resolution of approximately 70% of the condylomas after imiquimod treatment, and full resolution of all recalcitrant condylomas treated subsequently with high-intensity focused ultrasound. The method is concluded to be safe and effective and, furthermore, presents a new physical method that does not generate airborne infectious human papillomavirus particles that pose a health risk for the medical team performing therapy. Further studies in larger populations are recommended to confirm the combined efficacy of the proposed method.

Abstract
BACKGROUND Human papillomavirus is the most common sexually transmitted infection, usually passing from one person to another after the first sexual activity. Infection with this virus and the occurrence of genital warts (GWs) could have several effects on patients' health. This study was performed to evaluate the sexual function and sexual quality of life (SQOL) in men with GWs. METHODS This cross-sectional study was conducted from September 2019 to March 2020 with a sample size of 105 men with GWs in the dermatology clinic of Shahid Faghihi Hospital in Shiraz University of Medical Sciences, Iran. Data were collected using a demographic questionnaire, the International Index of Erectile Function (IIEF), and the Sexual Quality of Life-Men (SQOL-M) questionnaires and analyzed by descriptive and inferential tests with SPSS software version 22. RESULTS The mean score for overall sexual function in men was 48.50 ± 8.89. About 35.2% of men had overall sexual dysfunction (SD). The highest disorder rate was related to the erection domain (85.7%), and the lowest was related to the desire domain (5.7%). In the erection domain, most men (54.3%) experienced mild to moderate erectile dysfunction. The mean score for SQOL-M was 38.36 ± 14.47, and 56.2% of them had a good SQOL. CONCLUSIONS GWs affected men's erection more than the other sexual function domains. SD in men with GWs has a significant impact on their SQOL and ED was associated with impaired SQOL. Therefore, it is recommended to pay more attention to SD screening alongside SQOL assessment of men with GW.

Abstract
Background Human papillomavirus (HPV) is a well-known cause of cervical cancer. The prevalence of HPV, insufficient preventive services, inadequate treatment access, socioeconomic conditions, certain cultural causes and values and opinions regarding cervical cancer have been established as factors contributing to the occurrence of cervical cancer in various parts of the world. Objective To determine university students' knowledge, attitudes and perceptions regarding HPV and its vaccine. Material and Methods The present cross-sectional study included students enrolled at the University of Hail, Saudi Arabia. Data were collected from January to May 2020 using a previously validated 26-item questionnaire. Results A total of 386 participants responded to the survey; the response rate was 80%. The majority of the respondents (63%) were male and 332 (86%) respondents were single among the overall study population. Most respondents were aged 21-25 years (75.6%), followed by 26-30 years (12.7%). In total, 130 (33.7%) respondents reported that they had heard of HPV before, while 174 (45.1%) reported that HPV infections are rare in Saudi Arabia. Furthermore, 102 (26.4%) respondents thought that HPV causes genital warts, while almost 29.5% believed that HPV infection is a sexually transmitted disease. Nearly 76.2% of the respondents did not believe that HPV infection can occur without symptoms. Moreover, 53.4% of the respondents stated that they did not know the health problems associated with HPV infection, while 148 (38.8%) stated that cervical cancer is a health problem associated with HPV infection. When asked about their understanding of the HPV vaccine, nearly 267 (62.2%) respondents believed that there is no vaccine for HPV, while 239 (61.9%) believed that the vaccine does not minimise the risk of cervical cancer. In addition, the respondents reported that they would be far more likely to get an HPV vaccine if recommended by their doctors [relative importance index (RII) = 0.745], followed by their friends (RII = 0.675). Conclusion The present findings provide a clear understanding of university students' knowledge, perceptions and attitudes regarding HPV; this information can be used to raise awareness by developing an effective educational strategy. However, further research with a larger sample size is recommended; such efforts would also aid in the development of educational services for various age ranges.

Abstract
Purpose The anatomical distribution of perianal warts is associated with patient characteristics such as sexual orientation. The purpose of this study is to confirm this experiential knowledge using a quantitative classification system and analysis and to obtain findings useful for future treatment. Methods From January 2014 to December 2020, 93 patients with perianal warts presented to our hospital. Patients were analyzed for age, sex, lesion site, and recurrence type, among other factors. The lesion site was divided into skin (S) and anal epithelium (anoderm, A), and the number and degree of each were classified into grades 0 to 3. The higher grade between S and A determines its dominant type, such as type S (e.g., S3A1) and type A (e.g., S0A2). Results The average age of the patients was 39.6 years, and the percentage of patients who were not married was 54.8%. In all, 95.8% of patients were positive for low-risk human papillomavirus (HPV). Type S accounted for 80.6%, whereas type A accounted for 9.7%. Type A cases were all male and were all presumed to be men who have sex with men (MSM). This indicates that the determination of type A may be highly specific for MSM. The type at the time of recurrence was the same type at the time of the first surgery in almost all cases. Conclusion In cases of perianal warts, it is useful to analyze the lesion by considering the range and grade separately for daily clinical practice on proctologist.

Abstract
BACKGROUND Genital wart (GW) is known as an infectious disease. Besides the infection, it is associated with a higher risk of cervical neoplasia and cancer in the infected population. The present research aimed to explore the predictors of GW preventive behaviors based on the health belief model (HBM). METHODS The present analytical and cross-sectional research was conducted in 2019 among 720 women between 15 and 49 years of age in Bandar Abbas in the south of Iran. The sample was selected in a multi-stratified clustering method. The participants responded to a reliable and valid researcher-made questionnaire which explored demographic information, knowledge-related items and the model constructs. A multivariate linear regression analysis was run to determine the predictors of adopting GW preventive behaviors. A path analysis was also run to test the direct and indirect effects of the model constructs on the dependent variable. RESULTS The mean and standard deviation of participants' age was 30.43 ± 8.697 years. As Pearson's correlation coefficients showed, knowledge (r = 0.197, p < 0.001), perceived susceptibility (r = 0.434, p < 0.001), severity (r = 0.463, p < 0.001) and self-efficacy (r = 0.434, p < 0.001) were significantly correlated with the adoption of GWs preventive behaviors. Multiple linear regression analysis showed that self-efficacy (B = - 0.010, p < 0.001), perceived susceptibility (B = 0.070, p < 0.001) and severity (B = 0.078, p < 0.001) were the predictors of GW preventive behaviors. Path analysis showed that perceived susceptibility, severity and self-efficacy directly affected healthy behaviors while perceived benefits and barriers indirectly affected the preventive behaviors. CONCLUSIONS The present findings help to promote knowledge of the predictors of GW preventive behaviors. HBM can be a useful theoretical framework to evaluate the preventive behavior of the disease and help to reduce the rate of sexually-transmitted infections including GW.

AIMS To estimate the incidence rates of genital warts (GWs) in women and men with type 1 diabetes compared to persons without diabetes. METHODS In this nationwide registry-based cohort study, we included the entire population aged 15 to 49 years living in Denmark between 1996 and 2016. From national registries, we retrieved individual level information on diabetes status, diagnoses and treatment of GWs, and potential confounding variables. We used Poisson regression to model sex- and age-specific incidence rates of GWs in persons with type 1 diabetes and persons without diabetes. Based on the models, we computed sex-specific incidence rate ratios (IRRs) of GWs in persons with type 1 diabetes compared to persons without diabetes, overall and according to age. RESULTS The analysis included 3,514,824 persons without type 2 diabetes and no GW diagnoses before baseline. The incidence rate of GWs in persons with type 1 diabetes was higher than in those without diabetes, both among women (IRR = 1.59; 95% CI, 1.42-1.78) and men (IRR = 1.36; 95% CI, 1.25-1.48). The pattern of increased incidence rates of GWs in persons with type 1 diabetes was seen at all ages. CONCLUSIONS Persons with type 1 diabetes have higher incidence rates of GWs than persons without diabetes. This supports the importance of HPV vaccination of young girls and boys with type 1 diabetes.

Abstract
BACKGROUND The quadrivalent human papillomavirus (HPV) vaccine was introduced in the Portuguese National Immunization Program in October 2008, targeting 13-year-old girls. This study aimed at evaluating the impact of HPV vaccination on the epidemiology of genital warts (GWs) in Portugal. METHODS Observational, retrospective chart review study conducted at two free-of-charge walk-in sexually transmitted diseases (STD) clinics in Lisbon region. The medical records of all patients attending a first STD consultation at the study centers between May 2006 and December 2017 (observation period) were reviewed. The number of patients diagnosed with GWs and/or chlamydial infection at each year was documented and used to determine yearly prevalence of both conditions throughout the observation period. We broke down the observation period into pre-vaccination (May 2006 to December 2008) and vaccination (January 2009 to December 2017) periods. RESULTS Most patients were male (69.5%) and aged ≥ 25 years (78.1%). The majority of male patients were men who have sex with women (62.0%). Marked decreases in the prevalence of GWs between the last year of the pre-vaccination period (2008) and the last year of the observation period (2017) were found for female patients aged ≤ 19 and 20-24 years (86.8% and 77.4%, respectively). Lower decreases were observed for male patients of the same age groups (38.5% and 19.3%, respectively). GWs prevalence increased among patients ≥ 25 years (9.7% and 14.7% among female and male patients, respectively). Overall prevalence of chlamydial infection increased by 75.9% between 2008 and 2017. CONCLUSIONS This study contributes to the body of evidence showing that public HPV vaccination programs are effective in reducing the prevalence of GWs among vaccine-eligible patients. HPV vaccination program may significantly reduce the burden associated with GWs in Portugal.

Abstract
BACKGROUND Genital warts (GWs) are highly prevalent among Iranian women. GWs are not only highly infectious but are also followed by severe adverse effects, including the development of cervical cancer. Therefore, the present study aimed to explore the effect of an educational intervention based on the health belief model (HBM) on the adoption of GWs preventive behaviors by married women in Bandar Abbas, a city in the south of Iran. METHODS A quasi-experimental intervention was conducted between 2019 and 2020 among 150 women participants (75 as the intervention and 75 as the control group). The sampling method was multi-stage clustering. The required data was collected using a reliable and valid tripartite questionnaire which explored demographic information, awareness, and HBM constructs. A total number of 15 educational sessions were held, each 90 min long. The control group received only one 90-min session. The final follow-up was completed three months after the intervention in November 2020. RESULTS The two research groups had no statistically significant differences in terms of awareness, perceived susceptibility, severity, benefits, barriers, and self-efficacy before the intervention (in the pre-test) (p > .05). After the educational intervention, the two groups showed statistically significant differences in all constructs except for the perceived benefits (p < .001). In the intervention group, in the pretest (before the intervention), the behavior score was 2.77 ± 2.59, which was increased to 3.73 ± .52 after the intervention (p < .001). In the control group, however, the difference was not statistically significant (p = 0.227). CONCLUSION The present findings showed that the educational intervention based on the HBM can improve the prevalence of GWs preventive behaviors in women. This education should be provided by experts at regular intervals in all healthcare centers.

Abstract
Introduction In Hong Kong (HK), a single-cohort vaccination program for 10–12-year-old girls with the 9-valent human papillomavirus (HPV) vaccine (9vHPV; types 6/11/16/18/31/33/45/52/58) has been launched. This study assessed the public health impact and cost-effectiveness of implementing routine 9vHPV vaccination (12-year-olds) with or without catch-up 9vHPV vaccination (13–18-year-olds) in HK. Methods The health impact and costs of implementing routine 9vHPV vaccination with or without catch-up vaccination over a 100-year time horizon were evaluated using a validated HPV-type transmission dynamic model adapted to the HK population; analyses were performed from a healthcare payer perspective. Routine vaccination (12-year-old girls) and catch-up vaccination (13–18 years) assumed vaccine coverage rates of 70% (base case) and 30%, respectively. The model also assumed herd immunity, lifelong vaccine protection, a discount rate of 3%, and a cost per dose of HK dollars (HKD) 858 [United States dollars (USD) 110] and HKD 1390 (USD 179) for the 2-valent HPV (2vHPV) and 9vHPV vaccines, respectively. HPV disease-related incidence and the incremental cost-effectiveness ratio (ICER) per quality-adjusted-life-year (QALY) were estimated. Cost-effectiveness was determined at a ceiling threshold of HK dollars (HKD) 382,046 (USD 49,142) or 1.0 times the gross domestic product per capita of HK. Results Compared with routine 9vHPV alone, routine plus catch-up 9vHPV is projected to reduce cervical cancer incidence by 3.4%. Routine plus catch-up 9vHPV will also reduce genital warts incident cases for males/females by 2.6%/5.4%. The incremental cost-effectiveness ratios were HKD 29,911 (USD 3847)/quality-adjusted life-year (QALY) for routine plus catch-up 9vHPV versus routine 9vHPV alone and HKD 25,524 (USD 3283)/QALY for routine 9vHPV alone versus screening only. Sensitivity analyses indicated that routine plus catch-up 9vHPV compared with routine 9vHPV alone remained cost-effective at coverage rates of 30% and 90%. Conclusions This analysis predicts that the current HK vaccination strategy can be considered cost-effective and will provide maximum health benefit. These results support addition of the routine 9vHPV vaccine with or without catch-up 9vHPV vaccination to the regional vaccination program in HK.

Abstract
Background Human papillomavirus (HPV), primarily genotypes 6 and 11, cause the majority of cases of anogenital warts (AGW). Although benign, AGW are associated with a substantial economic and psychosocial burden. Several vaccines have been developed to prevent HPV. The objective of this study was to describe the epidemiology and healthcare resource utilization of AGW in Morocco, as well as the associated costs of treatment from the public healthcare perspective. Methods This was a descriptive analysis of questionnaire data obtained via a Delphi panel. The panel consisted of 9 physicians practicing in public hospitals in Morocco (4 dermatologists and 5 obstetricians/gynecologists). The questionnaire collected data on physician and practice characteristics, diagnostic tests and procedures, treatments, and follow-up (including recurrence) of patients with AGW. Questionnaire items on which ≥ 70% of respondents agreed were considered as having consensus. Costs associated with diagnosis, treatment, and follow-up were calculated in Moroccan dirham (MAD) and converted to euros (€) based on official national price lists for public hospitals and the HCRU estimates from the questionnaire. Results The physician-estimated prevalence of AGW in Morocco was 1.6%-2.6% in women and 2.0%-5.3% in men. A mean (median) of 6.4 (4) patients per month per physician sought medical attention for AGW. Simple observation was the most common diagnostic method for AGW in both men and women, and excision was the most prescribed therapy (75%), requiring a mean of 2 visits. Recurrence occurred in approximately 27% of patients. The cost per case of managing AGW, including recurrence, was estimated at 2182–2872 MAD (€207–272) for women and 2170–2450 MAD (€206–233) for men. The total annual cost of medical consultations for AGW in Morocco ranged from 3,271,877 MAD to 4,253,703 MAD (€310,828–404,102). Conclusions Expert consensus indicates that AGW represent a significant burden to the Moroccan public healthcare system. These data can inform policy makers regarding this vaccine-preventable disease. Supplementary Information The online version contains supplementary material available at 10.1186/s13027-021-00403-1.

Abstract
Introduction: Genital condylomatosis is a highly contagious disease caused by the human papilloma virus (HPV). The aim of this prospective multicentre study was to evaluate the safety and efficacy of the Holmium:YAG (yttrium-aluminium-garnet) laser in the treatment of genital and intra-urethral warts; the secondary aim was to assess the patients' postoperative satisfaction and cosmetic results. Methods: From December 2016 to March 2019, patients with genital warts were prospectively enrolled in three hospitals. The inclusion criteria were male gender, age over 18 years-old and treatment-naïve. External and urethral genitalia warts were treated by the Holmium YAG laser. The follow-up analysis consisted of physical examination, flexible urethro-cystoscopy in case of meatal lesions, and administration of Dermatology Quality of Life Index (DLQI) and Patient Global Impression of Improvement (PGI-I) questionnaires at 1, 3, 6 and 12 months after surgery and subsequently yearly. Results: Sixty patients were enrolled. The single treatment was effective in 57/60 patients (95%). At a mean follow-up of 26 months, recurrences occurred in 8 patients (13.3%). No peri- or post-operative complication occurred. An improvement in pre-operative condition was highlighted with PGI-I and DLQI questionnaires. Conclusion: Our prospective multicentre study showed that holmium laser surgery seems to be a safe and effective treatment for external genital and urethral warts. Good dermatological outcomes aid to further improve patient satisfaction.

Abstract
BACKGROUND Under the influence of alcohol adolescents are more prone to engage in unprotected sex, which increases the risk of acquiring genital warts. The study aim was to examine whether alcohol consumption among adolescents is associated with acquiring genital warts. METHODS Health behavior data were extracted from the Danish National Youth Study 2014. Complete data were available for 63,648 students. Number of binge drinking episodes in the past 30 days, frequency of drinking on weekends and total number of drinks consumed during 7-day week were collected by a questionnaire. Information on genital warts for the period between filling the questionnaire in 2014 and December 31, 2018 was retrieved from the Danish National Prescription Register and Danish National Patient Register. RESULTS Adjusted analysis showed that, compared to students who did not drink alcohol, increasing frequency of binge drinking in the past 30 days was independently associated with greater hazard of acquiring genital warts (1-3 times hazard ratio [HR]: 1.36, 95 % confidence interval [CI]: 1.09-1.69; 4-6 times HR: 1.55, 95 % CI: 1.22-1.96; >6 times HR: 1.84, 95 % CI 1.39-2.45). Compared to students who did not drink alcohol, consistent alcohol drinking every weekend was associated with greater risk of developing genital warts (HR: 1.62, 95 % CI: 1.20-2.17). Total weekly number of alcohol drinks consumed was not associated with occurrence of genital warts. CONCLUSION Increased alcohol intake was associated with occurrence of genital warts over 4 year of follow-up. There is an urgent need for change of excessive alcohol intake tendencies among adolescents.

Abstract
OBJECTIVES To estimate the cost of six different techniques used to treat Genital Warts and the annual average cost of treating a typical GW patient in Peru. To estimate the annual economic burden diagnosing and treating GW in the Peruvian public healthcare system. METHODS We developed a prevalence-based, cost-of-illness study from the provider's perspective, the healthcare facilities under the purview of Peruvian Ministry of Health. We used an activity-based costing approach. We conducted primary data collection in three regions in Peru and supplemented it with governmental data. Uncertainty of the costing estimates was assessed via Monte Carlo simulations. We estimated the average cost and associated confidence intervals for six treatment options - three topical and three surgical - and the overall cost per patient. RESULTS The average treatment cost per patient was 59.9USD (95 %CI 45.5, 77.6). Given a population of 18.4 million adults between 18 and 60 years of age and a GW prevalence of 2.28 %, the annual cost of treating GW was 25.1 million USD (uncertainty interval 16.9, 36.6). CONCLUSIONS This study provides the first quantification of the economic burden of treating genital warts in Peru and one of the few in Latin America. The costing data did not include other healthcare providers or out-of-pocket expenditures, and hence we present a conservative estimate of the COI of GW in Peru. Our findings bring attention to the financial burden of treating GW, a vaccine-preventable disease.

Abstract
Background: Substantial declines in genital warts have been observed in countries with quadrivalent/nonavalent human papillomavirus (q/n HPV) vaccination programmes, with Australia showing the most pronounced and long-term reductions. No study has assessed progress towards elimination of genital warts in a nation-wide sample of patients, and migrants' contribution to population-level control of genital warts. We assessed Australia's progress towards genital warts elimination by examining trends in diagnoses in Australian- and overseas-born patients of sexual health clinics (SHCs) across Australia. Methods: A cross-sectional trend analysis of new genital warts diagnoses among first-time patients of 34 SHCs, between 2004 and 2018, was performed. Rate ratios (RR) were calculated using Poisson regression models, for comparing trends in proportions of new genital warts diagnoses in Australian- and overseas-born patients during the pre-vaccination era (2004-2007) and the vaccination era (2008-2018), and by 2018 relative to 2004-2007. Findings: A total of 439,957 new patients (Australian-born: 230,230; overseas-born: 209,727) were seen at SHCs, 6•4% were diagnosed with genital warts (Australian-born: 7•1%; overseas-born: 5•6%). By 2018, there had been a 64% reduction in the proportion of all SHC patients with a genital warts diagnosis relative to 2004-2007 (RR: 0•36, 95% CI: 0•35-0•38). The decline was more pronounced at 72% (RR: 0•28, 95% CI: 0 •27-0•30) among Australian-born patients, with the greatest reduction in women and men aged <21 years, at 98% (RR: 0•02, 95% CI: 0•01-0•03) and 92% (RR: 0•08, 95% CI: 0•06-0•11), respectively. By 2018, there was a 49% reduction in the proportion of overseas-born patients diagnosed with genital warts (RR: 0•51, 95% CI:0•48-0•54), and a 21% reduction in overseas-born patients from countries with no or bivalent HPV (bHPV) vaccination programme (RR: 0•79, 95% CI: 0•71-0•90). Interpretation: The substantial reductions in Australian-born people is a testament to the efficacy of quadrivalent (qHPV) and nonavalent (nHPV) vaccines and the high and wide-spread vaccination coverage in Australia. However, population-wide elimination of genital warts in Australia is dependent on other countries initiating or expanding their own HPV vaccination programmes.

Abstract
OBJECTIVES This is a randomized controlled clinical trial comparing Photodynamic Therapy (PDT) and the application of trichloracetic acid (TAA) in the treatment of HPV condyloma in the perianal and vulva regions. Design, Randomised controlled, open label, trial. They were allocated to each treatment following randomization by a computer program. SETTING Women Health Ambulatory in São Carlos city, São Paulo State in the Brazil. PARTICIPANTS 36 patients evaluated. 31 patients fulfilled the study requirements. INTERVENTION Photodynamic Therapy (PDT) versus trichloracetic acid (TAA). The PDT protocol used the prodrug methyl aminolevulinate incubated for 3 hours and irradiation at 630 nm (100 J/cm²). In the treatment using TAA, warts received a small amount of acid using a cotton swab. Both treatments were repeated weekly until the lesions disappeared completely or until 10 sessions were completed. MAIN OUTCOME MEASURE Clinical analysis. Follow-up between 12 and 30 months after the complete treatment. RESULTS A total of 16 patients were treated with PDT and 15 patients with TAA. A complete response rate of 60% for TAA and 63% for PDT, with a recurrence rate of 33% for TAA and 0% for PDT. CONCLUSION PDT appears not only to treat lesions due to physical destruction of condyloma and subclinical lesions, but also to modulate the immune system and/or also to decrease the local viral load, suggesting a lower recurrence compared to the TAA group.

Abstract
BACKGROUND Numerous studies have confirmed that 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) is an effective treatment for human papillomavirus-associated diseases. In this study, we evaluated the variables associated with human papillomavirus (HPV) persistence or clearance after ALA-PDT in patients with genital warts. METHODS We performed a retrospective chart review of all patients with genital warts or subclinical HPV infection who received ALA-PDT treatment between January 2019 and December 2020 at Nanfang Hospital and Dermatology Hospital of Southern Medical University and analyzed the predictors of HPV persistence or clearance. HPV genotype and viral load assays were analyzed before treatment and after each session of photodynamic therapy. RESULTS Multiple sexual partners, a history of recurrent HPV infection, and severe pain response during photodynamic therapy were associated with higher odds of viral persistence after three rounds of ALA-PDT. Infection with single strains of HPV, and mucosal and subclinical infection were more likely to be cleared after three rounds of photodynamic therapy. CONCLUSION Our findings suggest that patients with multiple sexual partners, a history of recurrent infections, and severe pain response during photodynamic therapy should undergo close surveillance and monitoring, and may need additional photodynamic therapy sessions. Infection with a single strain of HPV, and mucosal or subclinical infections are more likely to be cleared after three courses of ALA-PDT treatment. These findings may improve the efficiency of ALA-PDT in clinical practice.

Abstract
BACKGROUND The introduction of human papillomavirus (HPV) vaccination has resulted in a remarkable decline of genital warts in women and men, but in Germany historical rates of vaccination are relatively low. We report long-term surveillance data on changes in HPV 6 and HPV 11 infection and the prevalence of genital warts in young women in the Wolfsburg HPV epidemiological study (WOLVES). METHODS Women born in 1983/84, 1988/89, and 1993/94 participated in four cohorts between 2009/10 and 2014/15. Quadrivalent vaccination coverage and prevalence of HPV 6/11 infection and genital warts are reported for participants aged 19-22 years and 24-27 years at the time of sample collection. Statistical analyses were done to compare similarly aged participants using 2 × 2 contingency tables (Röhmel-Mansmann unconditional exact test; two-side alpha of 0.05). RESULTS A total of 2456 women were recruited. Between 2010 and 2015, there was a statistically significant decrease in the prevalence of HPV 6 infection among women aged 24-27 years (2.1% versus 0.0%; P < 0.0001) and women aged 19-22 years (2.0% versus 0.0%; P = 0.0056). There was no significant decline in HPV 11 infection. In total, 52 of 2341 participants were diagnosed with genital warts. There was a statistically significant drop in the risk of developing genital warts in women aged 24-27 years between 2010 and 2015 (4.7% versus 1.7%, respectively; P = 0.0018). The overall risk of developing genital warts in women aged 19-27 years decreased from 3.1% in 2010 to 1.2% in 2015 (P = 0.0022). CONCLUSIONS An increase in vaccination coverage was associated with a decreased prevalence of genital warts in young women. A protective effect greater than herd immunity alone was seen despite low vaccination rates. Quadrivalent vaccine had a protective effect on genital HPV 6 infection and an almost fully protective effect on the development of genital warts in the youngest population.

Abstract
BACKGROUND The National HPV Immunisation Programme was introduced in England in September 2008 using the HPV16/18 bivalent vaccine. We conducted serological surveillance to explore vaccination coverage levels. We also conducted a case-control study to investigate a hypothesised cross-protective effect of the HPV16/18 vaccine against genital warts. METHODS Residual serum specimens from 16 to 20 year-old women attending six specialist sexual health services (SSHS) between 2011 and 2015 in England were tested for antibodies against HPV16 and HPV18 using a virus-like particle (VLP)-based multiplex serology assay. Patients were classified as having vaccine-induced seropositivity if they were seropositive for both HPV types and either had high antibody levels for at least one HPV type, or moderately high levels for both HPV types. Differences in vaccine-induced seropositivity by patient characteristics were investigated using logistic regression. Vaccine-induced seropositivity was then compared for patients with genital warts (cases) and matched patients without (controls). RESULTS Of 3,973 serum specimens collected, 3,870 (97.4%) had a valid result. The proportion of women with vaccine-induced seropositivity decreased with age (from 78.1% in 16-year-olds to 52.6% in 20-year-olds). Vaccine-induced seropositivity was lower among women born outside the UK, from more deprived areas and with a history of chlamydia diagnosis. A difference in uptake by ethnic group was also seen but this was largely confounded by differences in deprivation and country of birth. Among 537 cases and 1,515 controls, there was little evidence of a protective effect of the bivalent HPV vaccine against genital warts (adjusted odds ratio 0.93; 95% CI: 0.74-1.18). DISCUSSION Vaccine-induced seropositivity in this high-risk population was in line with vaccination coverage in the general population although was lower in some at-risk sub-groups. This study does not provide evidence to support a cross-protective effect of the HPV16/18 vaccine against genital warts.

Abstract
Ustekinumab is a fully human monoclonal antibody targeting the pro-inflammatory cytokines interleukin (IL)-12 and IL-23 approved for the treatment of psoriasis and psoriatic arthritis. We report a case of a patient treated for chronic plaque psoriasis with ustekinumab who developed bulky condyloma acuminata shortly after initiating the treatment. Although ustekinumab has already been described in literature associated with other forms of human papilloma virus skin infections, this is the first case to our knowledge in which ustekinumab is associated with genital warts.

Abstract
Human papillomaviruses (HPVs) can cause both benign and malignant tumors. To date, more than 200 HPV types have been discovered, of which 12 are currently classified as high risk for cervical cancer. HPV types that affect the anogenital tract are sexually transmitted. Since 2006, prophylactic HPV vaccines have been available and should be administered before first sexual contact.HPVs infect epithelial cells and are worldwide the most common sexually transmitted viruses. Apart from cervical cancer, HPVs cause other anogenital cancers such as vulvar, vaginal, and anal cancer but also oropharyngeal cancer (or head and neck cancers). HPV types 16 and 18 are also found at these sites. HPV types 6 and 11 are associated with genital warts; other HPV types can cause harmless skin warts.HPV vaccines are safe and highly effective, if they are administered before exposure to HPV. Systematic reviews and meta-analyses have shown that HPV vaccination effectively prevents HPV infection, but also precancerous lesions of the anogenital tract and genital warts. Recent vaccination data also demonstrate reductions in cervical cancer incidence.The uptake rates of HPV vaccination vary worldwide by program and acceptance. In comparison to other European countries, Germany has a low uptake rate. The Standing Committee on Vaccination (STIKO) recommends HPV vaccinations for all girls and boys ages 9 to 14 years in Germany. In 2018, only half of all 18-year-old girls in Germany were completely immunized against HPV.Organized vaccination programs, whether population-based or school-based, are necessary in order to increase vaccination uptake rates.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has significantly affected utilization of preventative health care, including vaccines. We aimed to assess HPV vaccination rates during the pandemic, and conduct a simulation model-based analysis to estimate the impact of current coverage and future pandemic recovery scenarios on disease outcomes. The model population included females and males of all ages in the US. The model compares pre-COVID vaccine uptake to 3 reduced coverage scenarios with varying recovery speed. Vaccine coverage was obtained from Truven Marketscan™. Substantially reduced coverage between March-August 2020 was observed compared to 2018-2019. The model predicted that 130,853 to 213,926 additional cases of genital warts; 22,503 to 48,157 cases of CIN1; 48,682 to 110,192 cases of CIN2/3; and 2,882 to 6,487 cases of cervical cancer will occur over the next 100 years, compared to status quo. Providers should plan efforts to recover HPV vaccination and minimize potential long-term consequences.

Abstract
Background Combined with cancer screening programs, vaccination against human papillomavirus (HPV) can significantly reduce the high health and economic burden of HPV-related disease in Japan. The objective of this study was to assess the health impact and cost effectiveness of routine and catch-up vaccination of girls and women aged 11–26 years with a 4-valent (4vHPV) or 9-valent HPV (9vHPV) vaccine in Japan compared with no vaccination. Methods We used a mathematical model adapted to the population and healthcare settings in Japan. We compared no vaccination and routine vaccination of 12–16-year old girls with 1) 4vHPV vaccine, 2) 9vHPV vaccine, and 3) 9vHPV vaccine in addition to a temporary catch-up vaccination of 17–26 years old girls and women with 9vHPV. We estimated the expected number of disease cases and deaths, discounted (at 2% per year) future costs (in 2020 ¥) and discounted quality-adjusted life years (QALY), and incremental cost effectiveness ratios (ICER) of each strategy over a time horizon of 100 years. To test the robustness of the conclusions, we conducted scenario and sensitivity analyses. Results Over 100 years, compared with no vaccination, 9vHPV vaccination was projected to reduce the incidence of 9vHPV-related cervical cancer by 86% (from 15.24 new cases per 100,000 women in 2021 to 2.02 in 2121). A greater number of cervical cancer cases (484,248) and cancer-related deaths (50,102) were avoided through the described catch-up vaccination program. Routine HPV vaccination with 4vHPV or 9vHPV vaccine prevented 5,521,000 cases of anogenital warts among women and men. Around 23,520 and 21,400 diagnosed non-cervical cancers are prevented by catch-up vaccination among women and men, respectively. Compared with no vaccination, the ICER of 4vHPV vaccination was ¥975,364/QALY. Compared to 4vHPV, 9vHPV + Catch-up had an ICER of ¥1,534,493/QALY. Conclusions A vaccination program with a 9-valent vaccine targeting 12 to 16 year-old girls together with a temporary catchup program will avert significant numbers of cases of HPV-related diseases among both men and women. Furthermore, such a program was the most cost effective among the vaccination strategies we considered, with an ICER well below a threshold of ¥5000,000/QALY.

Abstract
BACKGROUND Genital warts are a common and highly contagious sexually transmitted disease. They have a large economic burden and affect several aspects of quality of life. Incidence data underestimate the real occurrence of genital warts because this infection is often under-reported, mostly due to their specific characteristics such as the asymptomatic course. METHODS Genital warts cases for the analysis were obtained from the Catalan public health system database (SIDIAP) for the period 2009-2016. People under 15 and over 94 years old were excluded from the analysis as the incidence of genital warts in this population is negligible. This work introduces a time series model based on a mixture of two distributions, capable of detecting the presence of under-reporting in the data. In order to identify potential differences in the magnitude of the under-reporting issue depending on sex and age, these covariates were included in the model. RESULTS This work shows that only about 80% in average of genital warts incidence in Catalunya in the period 2009-2016 was registered, although the frequency of under-reporting has been decreasing over the study period. It can also be seen that this issue has a deeper impact on women over 30 years old. CONCLUSIONS Although this study shows that the quality of the registered data has improved over the considered period of time, the Catalan public health system is underestimating genital warts real burden in almost 10,000 cases, around 23% of the registered cases. The total annual cost is underestimated in about 10 million Euros respect the 54 million Euros annually devoted to genital warts in Catalunya, representing 0.4% of the total budget.

Abstract
BACKGROUND Genital warts, caused by the human papillomavirus, are a common sexually transmitted disease. The warts can regress spontaneously or exhibit a persistent clinical course. Various therapeutic modalities are available, yet none is curative, and there may be recurrences. Retinoids are considered the mainstay of therapy in many dermatologic diseases. Data on their use for genital warts are limited. OBJECTIVE To systematically review the published evidence on the efficacy and safety of retinoids for the treatment of genital warts. METHODS A systematic review and meta-analysis of all publications evaluating topical or systemic retinoids for the treatment of genital warts was performed. The primary outcome was complete response (CR); the secondary outcomes were recurrence rate and adverse events. RESULTS Six publications were evaluated, three randomized controlled trials and three prospective cohort studies, including a total of 141 patients with genital warts treated exclusively with retinoids (90% with isotretinoin). CR rates were 100% for systemic etretinate (3 out of 3 patients, 95% CI 28-81%) and 56% for isotretinoin (95% CI 28-81%; I2 = 84%). Topical etretinate did not induce CR. The most common side effect of topical agents was irritant contact dermatitis (36%) and that of systemic agents mucocutaneous disorders (80%). The relapse rate was 12% for oral isotretinoin and was unavailable for the other modalities. CONCLUSIONS Current data suggest that unlike topical retinoids, systemic retinoids are an effective and safe treatment for genital warts. Further studies are required to determine their specific role and the most effective regimen for each derivative.

Abstract
BACKGROUND Human papillomavirus (HPV) is a common sexually transmitted pathogen and the cause of several cancers and of anogenital warts. With this study, we estimated the trend of hospitalizations for anogenital warts (AGWs) in the Veneto region (Italy) from 2007 to 2018. METHODS The analysis included all the hospital discharge records of public and accredited private hospitals occurred in Veneto residents in the timespan 2007-2018. The ICD9-CM code 078.11 considered were those associated with condyloma acuminatum and those associated with surgical interventions for vulval/vaginal warts, penile warts anal warts. Annual total and sex- and age-specific hospitalization rates and trends were calculated and correlated with the different HPV vaccine coverage over the study period. RESULTS We observed an overall reduction of hospitalization rates for AGWs: from 15.0 hospitalizations every 100,000 Veneto residents in years 2007-08 to 10.9 hospitalizations every 100,000 Veneto residents in year 2017-18 (- 37.4%; p < 0.05). Reduction has been caused by a drop in hospitalizations in females - from a rate of 20.4/100,000 in 2007-2008 to a rate of 10.8/100,000 in 2017-18 (AAPC: -7.1; 95%CI: - 10.6;-3.4); while in males, we observed a slight - but not statistically significant - increase in hospitalization rates. CONCLUSION The marked decline in hospitalization rates for AGWs in Veneto Region is probably attributable to the high coverage rates of HPV vaccination programs implemented since 2008.

Abstract
Background External genital lesions (EGL) are the most common sexually transmitted infections (STIs). We aimed to evaluate the prevalence, determinants and sex differences in EGL among young adults from Brazil. Methods Overall, 7694 participants (aged 16 to 25 years) underwent an interview, genital examination and sampling for HPV genotyping. Results The prevalence of EGL was 4.08% (234) and is more frequent in men (5.72%) than women (2.31%) (p < 0.001). Genital lesions were significantly associated with male sex, infection by high-risk and multiple HPV types, having more than two sexual partners in the last year, smoking status and the presence of other STI. While alcohol use was associated with a higher prevalence of EGL in women, same-sex sexual relationship increase the prevalence in men. In the EGL group, 67.79% (p = 0.032) were positive for HPV infection and the types HPV6 and HPV11 were the most prevalent ones. Conclusion The prevalence of EGL in young adults was consistently high, and most cases were associated with genital HPV infection and STIs. Although men have a higher prevalence, both sexes share most genital lesion determinants. The promotion of sexual education and vaccination especially focus in young men, who are usually outside the targets of primary health care programmes, can prevent EGL in Brazilian young adults.

Abstract
Condyloma or genital warts affect the tissues of the genital area due to infections induced by Human papillomavirus. There are some topical therapies indicated for condyloma lesions treatment but all of them present a high rate of recurrence. Photodynamic Therapy is proving to be an interesting strategy for treating these lesions, capable also to treat virus-infected cells on subclinical lesions. A patient with a significative condylomatosis region was treated with six MAL-PDT sessions. Due to its large thickness, other topical procedures probably would have low effectiveness. After the treatment, the tissue presented clinical absence of lesion and no apparent scar, with good aesthetic result and preserving the sensitivity of the region and a follow up of eleven months without recurrence.

Abstract
Prevalence of co-infecting sexually transmitted infections (STIs) among patients newly diagnosed with anogenital warts is under-reported. Our objective is to determine the prevalence of six common STIs, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), genital herpes (herpes simplex virus type 2 [HSV-2]), HIV, and syphilis for patients visiting a sexual health clinic in Guangzhou, China. Demographics, sexual health, and medical histories were collected at patient intake. Patients diagnosed with anogenital warts (N = 200) were invited to participate. We collected urine samples, and urethral, cervical, and rectal swabs to test for CT, NG, and MG, and blood samples for serological detection of HSV-2, syphilis, and HIV. Overall 49 (24.5%) had a co-infection (22.2% of men and 27.7% of women). All six STIs were observed among men: CT (6.8%), NG (3.4%), MG (5.1%), HIV (4.3%), HSV-2 (4.3%), and syphilis (1.7%). Women had fewer STIs, but at higher rates: CT (13.3%), MG (6.0%), and HSV-2 (8.4%). Individual men had up to two co-infections, while women had no more than one co-infection. Chlamydia was the most common STI. Patients aged 18-25 years (35.4%) had the highest prevalence. Although opportunistic screening is often applied for high-risk groups, expansion to patients with anogenital warts in all health-care settings would improve detection of problematic asymptomatic co-infections, thereby increasing China's capacity to contribute toward global surveillance systems.

Abstract
Background Most individuals are infected with human papillomavirus (HPV) at least once in their lifetime. Infections with low-risk types can cause genital warts, whereas high-risk types can cause malignant tumors. The aim of this study was to determine the burden of anogenital diseases potentially related to HPV in young women based on German statutory health insurance claims data. Methods We conducted a retrospective claims data analysis using the “Institute for Applied Health Research Berlin” (InGef) Research Database, containing claims data from approximately 4 million individuals. In the period from 2012 to 2017 all women born in1989–1992, who were continuously insured between the age of 23–25 years were identified. Using ICD-10-GM codes (verified diagnosis in the outpatient sector or primary or secondary diagnosis in the inpatient sector) the administrative prevalence (95% confidence interval) of genital warts (A63.0), anogenital diseases grade I (K62.8, N87.0, N89.0, N90.0), grade II (N87.1, N89.1, N90.1) and grade III (D01.3, D06.-, D06.0, D07.1, D07.2, N87.2, N89.2, N90.2) was calculated (women with diagnosis divided by all women). Results From 2012 to 2017, a total of 15,358 (birth cohort 1989), 16,027 (birth cohort 1990), 14,748 (birth cohort 1991) and 14,862 (birth cohort 1992) women at the age of 23–25 were identified. A decrease of the administrative prevalence was observed in genital warts (1.30% (1.12–1.49) birth cohort 1989 vs. 0.94% (0.79–1.10) birth cohort 1992) and anogenital diseases grade III (1.09% (0.93–1.26) birth cohort 1989 vs. 0.71% (0.58–0.86) birth cohort 1992). In anogenital diseases grade III, this trend was especially observed for severe cervical dysplasia (N87.2) (0.91% (0.76–1.07) birth cohort 1989 vs. 0.60% (0.48–0.74) birth cohort 1992). In contrast, anogenital diseases grade I (1.41% (1.23–1.61) birth cohort 1989 vs. 1.31% (1.14–1.51) birth cohort 1992) and grade II (0.61% (0.49–0.75) birth cohort 1989 vs. 0.52% (0.42–0.65) birth cohort 1992) remained stable. Conclusions A decrease of the burden of anogenital disease potentially related to HPV was observed in the younger birth cohorts. This was observed especially for genital warts and anogenital diseases grade III. Further research to investigate this trend for the upcoming years in light of varying HPV vaccination coverage for newer birth cohorts is necessary.

Abstract
BACKGROUND Anogenital HPV is the most frequent sexually transmitted disease (STD) worldwide. There is no obligation to officially register HPV infections in Germany and thus the epidemiology of condylomata acuminata (CA) is not well characterized. OBJECTIVES To provide a better understanding of the epidemiology of CA and outline the treatment options that are available to patients with this disease. METHODS Data of 1124 patients with a confirmed diagnosis of CA, presenting in our university hospital outpatient consultation between 2011 and 2015 were retrospectively evaluated and the efficacy of various types of treatments was addressed. RESULTS A large patient cohort of 1124 predominately young (mean age 36.5 years old), male (83.9 %), single (50.2 %), heterosexual (92.8 %) Germans (62.5 %) received consults in our outpatient clinic for STDs. Nearly 60 % of the diagnosed patients presented with first-time CA, indicating a considerable proportion of roughly 40 % recurrent infections as well. Only 13.7 % of patients were previously immunized against HPV. CONCLUSIONS The evaluation of a large patient cohort provided a better understanding of the present epidemiology of CA in an outpatient hospital setting in Germany. An effective three-scale therapeutic regime and preventive measures were outlined.

Abstract
Polyphenon E 10%, a green tea extract containing epigallocatechin gallate (EGCG) as the main active compound, is a topical formulation indicated for the treatment of genital warts. Polyphenon E has also shown to be very effective in the treatment of periungual and plane warts. Here, we report a dramatic clinical effect of topical treatment with polyphenon E in a subject with multiple "seborrheic keratosis-like" lesions of the genital area. An immunocompetent 26-year-old Caucasian man came to our attention in October 2018. The subject, a regular blood donor, presented several (more than 100) light brown dome-shaped papular lesions in the groin area and in the penile shaft. A clinical diagnosis of Bowenoid papulosis-like multiple condylomata of the groin was made. A 2-month imiquimod treatment did not induce any relevant improvement in terms of volume and number of lesions. A treatment with Polyphenon E, a topical green tea extract with 10% of EGCG (Veregen®), was therefore started. After 2 months of Polyphenon E treatment, a dramatic reduction of the majority of the lesions was observed. After 3 months of treatment, all the lesions disappeared with only hyperchromic residues. Histological and immunohistological findings supported seborrheic keratosis as the conclusive diagnosis. This case report suggests that topical green tea extract could be very effective in the treatment of "seborrheic keratosis-like" lesions of the inguinal area.

Abstract
BACKGROUND The human papilloma virus (HPV) vaccination coverage rate in Japan has dropped dramatically from more than 70% to less than 1% since 2013. With conflicting information and a lack of quantification of the benefits and risks of the HPV vaccine, parents have been hindered in making their decision. We quantified the benefits and risks of the HPV vaccine in terms of quality-adjusted life-years (QALYs), to help their informed decision. METHOD A literature search was performed to determine the incidence and burden of each outcome in a decision tree model. The benefits and the risks of the HPV vaccination were determined in QALY change with a sensitivity analysis. RESULT The benefits of the HPV vaccine in terms of QALYs gained were 703.72, 14.45, and 30.83/100,000 persons for cervical cancer, cervical intraepithelial neoplasm 3 (CIN 3), and genital warts, respectively. The QALY loss due to acute adverse reactions, chronic adverse reactions without assistance needs, and chronic adverse reactions with assistance needs were 0.07, 5.83, and 5.82/100,000 persons, respectively. The risk/benefit ratio in QALY change in the base case was 0.0156. In all scenarios, the benefit of the HPV vaccine was significantly greater than the risk. CONCLUSION The benefits are much greater than the risks, even if it is assumed that all reported adverse events were due to the vaccination. The Japanese government and health care providers should immediately recommend the HPV vaccine to all adolescent girls irrespective of any causal links between the vaccine and reported adverse events.

Abstract
Background This study estimated genital warts prevalence, genital-warts-related healthcare resource use and costs, and self-reported human-papillomavirus-related psychosocial impact among male and female patients aged 18-60 years in the Philippines. Methods Prevalence was estimated using daily logs numbering genital warts patients treated by participating physicians in 4 Philippine regions over a 5-week period (09JUL2011-24SEP2012). Physicians also completed a survey assessing patient referral patterns, healthcare resource use, treatment, and follow-up care. Psychosocial impact was estimated using the human papillomavirus impact profile and the EQ-5D questionnaires. HIP and EQ-5D scores were compared according to the presence of GW (males) and HPV disease (females). CECA scores were also compared by gender and age groups. Results Overall genital warts prevalence was estimated at 4.78% (95% confidence interval [CI]: 4.58-4.98%) for men and women aged 18-60 years. Genital warts prevalence was 3.39% (95% CI: 3.13-3.65%) and 8.0% (95% CI: 7.69-8.31%) among women and men, respectively. Prevalence estimates were highest in infectious disease specialist practices 18.67% (95% CI: 18.66-18.69%). Two thirds of the 233 (69.14%) male and 166 (67.20%) female patients were newly-diagnosed genital warts cases. Median costs for genital warts diagnosis and treatment reached 7121 and 7000 Philippine pesos among men and women, respectively. In the Cuestionario Específico para Condiloma Acuminado questionnaire, no statistically significant differences between patients were observed. In the EQ-5D questionnaire, male genital warts patients reported lower mean visual analogue scale scores than those without genital warts (78.20 vs 86.34, p < 0.0001). Mean visual analogue scale score values and utility values were lower for women with human-papillomavirus-related diseases than those without (77.98 vs 78.93, and 0.84 vs 0.88, respectively). Conclusions Genital warts is prevalent in the Philippines; more than 60% of cases were newly diagnosed, contributing to high genital-warts-related healthcare resource costs. Diagnosis of genital warts and human papillomavirus negatively impacted psychosocial indices such as patient well-being and health-related quality of life.

Abstract
Anogenital warts, also known as condylomata acuminata caused by human papillomavirus constitute the most common sexually transmitted infection. Rarely, the disease may evolve into a huge cauliflower-like growth called giant condyloma acuminatum or Buschke–Löwenstein tumor (BLT). In contrast with normal anogenital warts, BLT displays local invasion, lack of spontaneous resolution, posttreatment recurrence, and potential for malignant transformation. Although radical excision with split-thickness skin grafting is considered its first-line treatment, it is not always feasible. While many other treatments have shown variable success and recurrence rates, topical imiquimod 5%, a popular evidence-based therapy for warts has also been reported as an efficacious treatment for BLT. We present a case of penile BLT where the patient refused surgery but recovered completely with no recurrence at five years following 16 weeks’ therapy with topical 5% imiquimod. Excepting a single reported case, this might be another case where BLT resolved with imiquimod as a standalone therapy. We also present a succinct review of past cases of BLT treated with imiquimod.

Abstract
Purpose Human papillomavirus (HPV) can cause condylomata acuminata, also known as genital warts. Our aim was to evaluate the long-term recurrence of genital warts after primary carbon dioxide laser treatment before the introduction of the vaccination against HPV. Methods Recurrence rate and localization of genital warts were analysed in a retrospective study in 1798 women presenting with a new diagnosis of genital warts from 1992 to 2009 at a University hospital and had received laser treatment. Additionally, data on topography, pregnancy status, and cervical smear were available for women treated from 2003 to 2009 (n = 825, data subset 1) and systematic follow-up data for women treated in 2006 and 2007 (n = 242, data subset 2). Results Median time from laser treatment to first recurrence was 14.6 weeks (data subset 2). The site most affected was the vulva (90.7%) followed by the perineum/perianal region (59.3%) and the vagina (47.3%). Abnormal Pap smear was observed in 22.6%. Systematic follow-up with a median follow-up time of 3.1 years revealed at least one recurrence in 68 (28.1%) of 242 women. Women with multifocal genital warts had a 2.9 times increased risk for recurrence compared to women with unifocal lesions (p = 0.01). Conclusions Nearly 30% of women presenting with genital warts experienced at least one recurrence after treatment with carbon dioxide laser. Multifocal lesions are the strongest indicator of recurrence. These data provide an important insight to recurrence rates of genital warts before HPV vaccination and underline the significance of a long-term follow-up and HPV vaccination.

Abstract
Herein we report three married women referred to Dermatology Clinic of Loghman Hakim Hospital, Tehran, Iran in 2017 for evaluation and treatment of genital warts. Two patients were complaining of flat-topped papules on their labia major and the third one was presented with asymptomatic papillary projections on her vestibule and inner aspect of both labia minora. Histological examination revealed the diagnosis of syringoma, lymphangioma circumscriptum (LC) and vestibular papillomatosis respectively. Familiarity with these uncommon conditions which clinically mimic genital warts helps to prevent labeling a patient with sexually transmitted disease before histological confirmation and prevent unnecessary treatment.

Abstract
Condylomata acuminata (CA), or anogenital warts, is the most common sexually transmitted infection. Treatments for CA generally have suboptimal recurrence rates, which results in a need for repeated treatments and adds to the already negative impact on the patients’ quality of life. CA can present at the urethral meatus, which is a particularly challenging anatomic location from a therapeutic perspective. We report two cases of CA at the urethral meatus successfully treated with topical application of high-dose ingenol mebutate gel.

Abstract
INTRODUCTION External ano-genital warts (AGWs) due to human papilloma virus infection are the most common sexually transmitted ano-genital lesions of viral origin worldwide. Treatments include topical chemicals/drugs, excisional surgery, cryosurgery, electrosurgery and laser surgery. Nitric-zinc complex (NZC) is a new topically applied solution containing nitric acid, zinc, copper and organic acids that induces a caustic effect on condyloma. The objective of this study was to investigate the efficacy and tolerability of NZC in the treatment of AGWs. METHODS Patients attending for AGWs between September 2016 and February 2018 were retrospectively studied. They received at least one NZC application for a maximum of four treatments (V0, V1, V2, V3) with average intervals of 25 days between sessions. Recurrences were evaluated at 3 and 6 months after clearance. RESULTS One hundred patients (70 males, 30 females) with a mean age of 36.39 years were studied. The total number of AGWs diagnosed at the baseline visit (V0) in all patients was 418 with a mean of 4.18 AGWs per patient. A wart cure rate of 92% was observed in ≤ 4 treatment sessions (383 lesions cured at visit 4, V4, out of 418 lesions at baseline), with a cure rate of 49% with only one NZC application. Complete clearance was observed in 25, 52, 72 and 84% of patients at V1, V2, V3 and V4, respectively. Relapses were observed in 29% of patients at 3 months and in 5% at 6 months. Of note, patients with ≤ 5 AGWs at V0 showed better clearance results than patients with > 5 lesions (p < 0.05). The treatment was well tolerated by most patients. CONCLUSION NZC has been demonstrated to be effective for AGWs after 1-4 treatment sessions, obtaining a good response from the first application. The better response in patients with fewer warts suggests that the earlier diagnosis is made and treatment started, the better the expected results. FUNDING ISDIN.

Abstract
Human papillomavirus (HPV) is one of the main causes of infection-related cancer. The bivalent vaccine (2vHPV) (16/18) and quadrivalent (6/11/16/18) HPV vaccine (4vHPV) have been included in the Spanish vaccination calendar since 2007. The new nonavalent HPV vaccine (9vHPV), approved in Europe in 2015, includes nine HPV types 6/11/16/18/31/33/45/52/58 and has been available in Spain since May 2017. Our study aims to estimate the epidemiological impact and the cost-effectiveness of a girls-only and a gender-neutral vaccination program with 9vHPV compared to the current vaccination program in Spain. A dynamic transmission model simulating the natural history of HPV infections was calibrated to the Spanish setting and applied to estimate costs and quality-adjusted life years (QALYs) associated with vaccination strategies using a payer perspective and a 100-year time horizon. A girls-only vaccination strategy at age 12 years with 9vHPV was found to be a cost-effective strategy compared with 4vHPV (incremental cost-effectiveness ratio (ICER) of €7,718 per QALY). Compared with girls-only vaccination with 4vHPV, gender-neutral vaccination with 9vHPV was associated with further reductions of up to 28.5% in the incidence of cervical intraepithelial neoplasia (CIN) 2/3 and 17.1% in the incidence of cervical cancer, as well as with a 14.0% reduction in cervical cancer mortality. Furthermore, a gender-neutral vaccination program with 9vHPV could potentially be cost-effective considering some parameters as head and neck protection or discount rates, leading to a reduction in the burden of HPV-related diseases in both sexes in the Spanish population.

Abstract
BACKGROUND Genital warts are important causes of morbidity and their prevalence and incidence can be used to evaluate the impact of HPV vaccination in a population. METHODS We enrolled 1020 women in a prospective cohort study in Nigeria and followed them for a mean (SD) of 9 (4) months. Nurses conducted pelvic examinations and collected ectocervical samples for HPV testing. We used exact logistic regression models to identify risk factors for genital warts. RESULTS The mean age of study participants was 38 years, 56% (535/962) were HIV-negative and 44% (427/962) were HIV-positive. Prevalence of genital warts at enrolment was 1% (4/535) among HIV-negative women, and 5% (23/427) among HIV-positive women. Of 614 women (307 HIV negative and 307 HIV positive women) for whom we could compute genital wart incidence, it was 515 (95% CI:13-2872) per 100,000 person-years in HIV-negative and 1370 (95% CI:283-4033) per 100,000 person-years in HIV-positive women. HIV was associated with higher risk of prevalent genital warts (OR:7.14, 95% CI:2.41-28.7, p < 0.001) while higher number of sex partners in the past year was associated with increased risk of incident genital warts (OR:2.86, 95% CI:1.04-6.47. p = 0.04). HPV11 was the only HPV associated with prevalent genital warts in this population (OR:8.21, 95% CI:2.47-27.3, p = 0.001). CONCLUSION Genital warts are common in Nigeria and our results provide important parameters for monitoring the impact of future HPV vaccination programs in the country. HIV infection and number of sexual partners in past year were important risk factors for prevalent and incident genital warts respectively.

Abstract
BACKGROUND Human papilloma virus (HPV) infection and condyloma acuminatum (CA) in the genital area often exist in extensive and multi-point fashion. Laser ablation combined with topical photodynamic therapy (PDT) is a feasible approach for genital CA but its effectiveness and limitations need to be evaluated. METHODS This single-arm prospective study consisted of 100 newly diagnosed CA cases of both sexes. All patients underwent laser ablation and then three times aminolaevulinic acid-based photodynamic therapy (ALA-PDT). The outcomes were evaluated and analyzed 3 months after the treatment. RESULTS A total of 98 patients completed the study. Except for 6 patients (4 males and 2 females) showed some residual lesions other 92 patients (93.8%) showed complete cure. However, there were 18 patients (10 males and 8 females) showed new lesions near the treated areas. Although the HPV types of 18 patients before and after treatment were not completely consistent, 94.4% percent of patients (17/18) had the same HPV type as the primary lesion, which suggested that these late-onset CA might have latent infection or subclinical infection in the early stage of the disease but the length of the incubation period was longer. CONCLUSION Combination approach is effective in treating genital CA and preventing CA recurrence. But its limitations need to be recognized as the late-onset CA might occur near the treated area. The treatment plan needs to be optimized for multiple genital CA lesions.

Abstract
Introduction: Genital warts in young adults aged 18-28 years are very common. Several approaches are routinely used in the treatment of warts, viz., medical treatment (podophyllin and trichloroacetic acid), conventional surgery (excision or electrocautery), cryotherapy, and laser treatment. Because of high recurrence rates after treatment, complications and long duration of treatment, newer modalities have been developed. One of these newer methods is laser, which has been used in several urologic diseases. However, there are only a few studies about use of Holmium laser for treatment of genital warts. This retrospective study compared the success rate of Holmium laser with other available treatments for genital warts. Methods: Between October 2011 and May 2016, 142 patients with genital warts attended the urology clinics at Shohada-e-Tajrish hospital in Tehran, Iran. Out of these, a total of 101 patients were included in this study consisting of 42, 39, 11 and 9 patients treated with cryotherapy, laser, conventional surgery and podophyllin respectively. Results: The most successfully cleared lesions were seen in the holmium laser treatment group (P=0.001). The lowest recurrence rate was observed in the holmium laser treatment group (P=0.001). 17 patients had one of these following problems: dysuria, initial hematuria or a change in the force and caliber of their urinary stream that after physical examination showed them to have a meatal wart. These patients then underwent cystoscopy up to urinary sphincter. All of them in addition to the meatus wart had a penile shaft lesion(s). Thirteen patients had meatal lesions, 9 of whom received holmium laser therapy and 4 patients were treated with electrocautery. Based on routine follow up after treatment, none of the patients treated with holmium laser had urinary stricture, but one case treated with electrocautery returned with a penile urethral stricture. Conclusion: This study showed that treatment with Holmium laser has the highest clearance rate (92.2%) and lowest recurrence rate (14.3%) compared to other available treatments in this study. It may be concluded that holmium laser is a safe and effective treatment for genital warts with a low rate of recurrence.

Abstract
Condyloma acuminata, also known as anogenital warts, represent a cutaneous infection caused by sexual transmission of the human papilloma virus. We present a case of overwhelming condyloma acuminata that was treated successfully without surgery using only topical imiquimod 3.75% cream. The patient, a 66-year-old female, was referred to Dermatology for large protruding verrucous plaques that covered the entire surface of her external vulva, perineum and perianal area. These lesions developed after being treated for genital warts with cantharidin. Four other cases treated with imiquimod were identified in the literature but either required surgery, higher doses or longer duration of treatment or involved pediatric populations. In patients who are not amenable to surgery, topical imiquimod may be a novel standalone or an adjunctive therapy for giant condyloma acuminata.

Abstract
BACKGROUND Human papillomavirus is a common sexually transmitted infection that may affect the oropharynx, genitalia, or anus. Some strains of this virus may cause bulky growths around the anus known as giant anal condylomas. These can become large, disfiguring, and may cause bleeding, as well as difficulty with defecation and hygiene. Surgical management is usually necessary for large condylomas, whereas office-based procedures are common for smaller lesions. It is unclear why some develop large anal margin tumors, whereas others develop limited disease. The aim of the present study was to evaluate for risk factors that may play a role in the development of extensive disease warranting operative management. MATERIALS AND METHODS A retrospective chart review of patients seen within the Anal Dysplasia Clinic at the Medical College of Wisconsin was undertaken. Clinic encounters for patients with anogenital condyloma were abstracted for demographic information, operative interventions, Human Immunodeficiency Virus status, and smoking history to determine risk factors that predicted operative intervention for giant anal condylomas. RESULTS A total of 239 patients met inclusion criteria; 211 (88.3%) were male and 28 (11.7%) were female. Racial makeup of the cohort included 49% Caucasian, 38.9% African-American, 9.2% Hispanic, and 2.9% were identified as another ethnicity. One hundred forty-three patients (60.1%) were current or past smokers. One hundred ninety-eight (82.8%) patients tested positive for human immunodeficiency virus (HIV), whereas 41 (17.2%) were negative. Multiple linear regression identified only African-American race as predictive of greater disease burden. CONCLUSIONS African-American race was associated with increased size of anal condyloma. As the size of anal condylomas increase, management shifts from topical treatments to operative intervention. This is the first study to correlate race with burden of disease in the general population.
