Abstract
Objective This study aimed to evaluate the prevalence of human papillomavirus (HPV) infection and presence of licensed HPV vaccine genotypes among patients with genital warts in Foshan, China from 2015 to 2022, to provide useful references for the detection, prevention and control of genital warts in Foshan. Methods The present study retrospectively analyzed the HPV detection rates in patients with genital warts. A total of 1,625 patients were seen at the Second People's Hospital of Foshan, Guangdong Province, China, from 2015 to 2022. Samples were collected from various lesions and genotyped for 21 genotypes of HPV by infusion hybridization. The classification principle of HPV genotypes in this study: (1) Based on the relationship between HPV and carcinogenicity; (2) Based on the number of HPV genotypes infected; (3) Based on the HPV genotypes of licensed HPV vaccines. Results The detection rate of any HPV in patients with genital warts was 80.37% (1,306/1,625). The detection rates of HPV for low-risk infection, co-infection and high-risk infection were 49.48% (804/1,625), 24.92% (405/1,625) and 5.97% (97/1,625), respectively. Single infection was the predominant type (51.94%, 844/1625). HPV-6 and HPV-11 were the predominant types of single infection; HPV-6 and HPV-52 were the predominant types of paired combinations of multiple infection. 82.22% (1,336/1,625) of the cases had an age distribution of ≤ 24, 25-34, and 35-44. The distribution of some HPV genotypes had age specificity, annual specificity and gender specificity. The genotype detection rates of 2v, 4v and 9v showed a decreasing trend with ages (all P < 0.05). The genotype detection rates of 4v and 9v showed a decreasing trend over the 8-year period (both P < 0.05). The genotype detection rates of 4v and 9v in the male group were higher than those in the female group (both P < 0.05). The genotype detection rate of 9v was significantly higher than that of 2v and 4v in the female group (both P < 0.05). Conclusion Our study demonstrated that low-risk infection and single infection were the main types of HPV infection in patients with genital warts, mainly among young patients. Our study provides epidemiological data for the detection, prevention and control of genital warts in China.

Abstract
Giant condyloma acuminatum (GCA), alternatively referred to as a Buschke-Löwenstein tumor (BLT), is an uncommon, benign, but locally aggressive form of verrucous carcinoma. The condition usually affects the male population under the age of 50 years; however, there have been rare reports of pediatric cases. Various risk factors such as smoking, diabetes, promiscuous behavior, poor hygiene, immunosuppression, and others are linked to the development of this condition. We present the case of a 26-year-old male patient who came to the dermatology department with primary complaints of 10-year-old verrucous tumor formations located in the perigenital and perianal areas. Serological tests for AIDS, hepatitis B, hepatitis C, Chlamydia trachomatis, and syphilis were negative. The routine blood tests were slightly abnormal. Histological verification of condylomata acuminata of Buschke-Löwenstein was made. Given the sensitive areas, surgery was advised. With several fine undermining scalpel excisions, the lesions in the scrotal and perigenital areas were removed and the dartos muscle was preserved. Electrodissection and shave curettage were not performed. The postoperative period passed without complications and no recurrences in the perigenital area were reported. We believe that our case report represents the first documented surgical approach for scrotal Buschke-Löwenstein tumor using exclusively fine undermining scalpel surgery. A brief literature review of the condition is presented, focusing on the currently available treatment options and highlighting the potential effectiveness of the surgical approach.

Abstract
Condyloma acuminatum (CA) is a sexually transmitted disease (STD) caused by human papillomavirus (HPV) infection. It is important to study the prevalence and distribution of HPV genotypes before implementing the HPV vaccination program. Therefore, the aim of this study was to evaluate the epidemiological characteristics of CA cases and the distribution of HPV genotypes in Shandong Province, China. One-to-one questionnaire surveys were conducted on all patients diagnosed with CA in sentinel hospitals from Shandong Province, China. HPV genotypes were determined using the polymerase chain reaction (PCR)-reverse dot blot hybridization method. The study enrolled 1185 patients (870 males and 315 females) and found that CA patients are mainly males and sexually active people between the ages of 20 and 40. Recurrence occurred in 34.7% patients. Among the 880 CA patients who underwent HPV typing, the HPV test positivity rate was 91.4%. In these cases, low-risk (LR) HPV infection was predominant, with an infection rate of 91.3%, while high-risk (HR) HPV genotypes were found in 53.5% patients. The most frequent HPV genotypes encountered were HPV6 (57.8%), HPV11 (37.2%), HPV16 (13.7%), and HPV42 (10.3%). HPV6 and/or HPV11 are the main infections in all patients, and more than half of the patients are coinfected with HR-HPV. However, unlike other regions, HPV42 has a higher prevalence rate among CA patients in Shandong Province and is a nonvaccine HPV genotype. Therefore, regular HPV typing helps to understand the characteristics of specific genotypes and the choice of the best type for vaccine coverage.

Abstract
Human papillomavirus (HPV) infection is associated with precancerous lesions and cancer of the genital tract both in women and men. The high incidence of cervical cancer worldwide focused the research on this infection mainly in women and to a lesser extent in men. In this review, we summarized epidemiological, immunological, and diagnostic data associated with HPV and cancer in men. We presented an overview of the main characteristics of HPV and infection in men that are associated with different types of cancer but also associated with male infertility. Men are considered important vectors of HPV transmission to women; therefore, identifying the sexual and social behavioral risk factors associated with HPV infection in men is critical to understand the etiology of the disease. It is also essential to describe how the immune response develops in men during HPV infection or when vaccinated, since this knowledge could help to control the viral transmission to women, decreasing the incidence of cervical cancer, but also could reduce other HPV-associated cancers among men who have sex with men (MSM). Finally, we summarized the methods used over time to detect and genotype HPV genomes, as well as some diagnostic tests that use cellular and viral biomarkers that were identified in HPV-related cancers.

[PMID: 38015627 PMCID: PMC10685781 DOI: 10.1177/10732748231218088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 10/09/2023] [Accepted: 11/07/2023] [Indexed: 11/30/2023] Open
Abstract
INTRODUCTION The epidemiology of human papillomavirus (HPV)-associated cancers has changed since the development of the multivalent vaccine. This is evidenced by the decline in incidence of cervical cancers in the post-vaccine era. By contrast, studies have reported the rise in incidence of these cancers in males. Though little is known regarding HPV-associated cancers in males, Hispanic males have been largely excluded from research on these cancers. OBJECTIVE The purpose of this study was to examine the differences in late-stage diagnosis of HPV-associated cancers (oropharyngeal, anorectal, or penile) among subgroups of Hispanic males in the U.S. METHODS We performed a population-based retrospective cohort study using the 2005-2016 North American Association of Central Cancer Registries Cancer in North America Deluxe data file (n = 9242). Multivariable logistic regression modeling was used in studying late-stage diagnosis. RESULTS There were no differences in late-stage diagnosis of oropharyngeal cancer between Hispanic subgroups. Higher odds of late-stage penile cancers were observed among Mexican and Puerto Rican males relative to European Spanish males. Lower odds of late-stage anorectal cancers were observed among Central or South American and Puerto Rican males. Having Medicaid or no insurance were associated with late-stage diagnosis for all cancers. CONCLUSION Certain subgroups of Hispanic males have higher odds of late-stage HPV-associated cancer diagnosis based on country of origin and insurance status. These findings call for improved efforts to increase HPV vaccination, particularly among these subgroups of Hispanic males. Efforts to improve health care access and early detection from health care providers are also needed.

Abstract
Urine cytology of urinary tract condylomas has not been systematically studied. We analyzed cytologic features of urinary tract condylomas and evaluated potential diagnostic challenges and pitfalls. We retrospectively reviewed urine cytology of urinary tract condylomas from 2 academic institutions (2015-2022). Among 20 patients with urinary tract condylomas, 6 had urine cytology (2 samples in 1 patient), including 3 men and 3 women (mean age, 74.3 years; range, 65-86 years). Original interpretations were negative for high-grade urothelial carcinoma (NHGUC; n = 4), atypical urothelial cells (n = 1), reactive urothelial cells (n = 1), and negative for malignancy (n = 1). Squamous cells were noted in 3 cases, atypical squamous cells (ASC) consistent with low-grade squamous intraepithelial lesion (LSIL) were noted in 1 case, and in 3 cases, the presence of squamous cells was not mentioned. All urines were reclassified according to The Paris System as NHGUC. Specimens were composed of benign urothelial cells and groups or isolated ASC consistent with LSIL (n = 4), atypical keratinized squamous cells (n = 2), and ASC that did not meet LSIL criteria (n = 1). The LSIL cells showed nuclear enlargement (n = 4), hyperchromasia (n = 4), perinuclear halo (n = 3), nuclear membrane irregularity (n = 4), orangeophilic cytoplasm (n = 3), and binucleation (n = 4). The atypical keratinized squamous cells showed hyperchromasia (n = 2), nuclear membrane irregularity (n = 2), keratin pearls (n = 2), and binucleation (n = 1). The ASC that did not meet LSIL criteria showed nuclear enlargement and orangeophilic cytoplasm. Many urinary tract condylomas (57%) demonstrate classic LSIL features in urine cytology. Less frequent cases can mimic keratinizing squamous cell carcinoma (28%) or demonstrate ASC not diagnostic of LSIL (15%).

Abstract
BACKGROUND Studies in women have shown an increased risk of human immunodeficiency virus (HIV) acquisition with prior human papilloma virus (HPV) infection; however, few studies have been conducted among men. Our objective was to assess whether HPV-related external genital lesions (EGLs) increase risk of HIV seroconversion among men. METHODS A total of 1379 HIV-negative men aged 18 to 70 years from the United States, Mexico, and Brazil were followed for up to 7 years and underwent clinical examination for EGLs and blood draws every 6 months. Human immunodeficiency virus seroconversion was assessed in archived serum. Cox proportional hazards and marginal structural models assessed the association between EGL status and time to HIV seroconversion. RESULTS Twenty-nine participants HIV seroconverted during follow-up. Older age was associated with a lower hazard of HIV seroconversion. We found no significant difference in the risk of HIV seroconversion between men with and without EGLs (adjusted hazard ratio, 0.94; 95% confidence interval, 0.32-2.74). Stratified analyses focusing on men that have sex with men found no association between EGLs and HIV seroconversion risk (hazards ratio, 0.63; 95% confidence interval, 0.00-1.86). CONCLUSIONS External genital lesions were not associated with higher risk for HIV seroconversion in this multinational population, although statistical power was limited as there were few HIV seroconversions. Results may differ in populations at higher risk for HIV.

Abstract
Penile squamous cell carcinoma (PSCC) is a rare cancer with orphan disease designation and a prevalence of 0.1-1 per 100,000 men in high-income countries, but it constitutes up to 10% of malignancies in men in some African, Asian and South American regions. Risk factors for PSCC include the absence of childhood circumcision, phimosis, chronic inflammation, poor penile hygiene, smoking, immunosuppression and infection with human papillomavirus (HPV). Several different subtypes of HPV-related and non-HPV-related penile cancers have been described, which also have different prognostic profiles. Localized disease can be effectively managed by topical therapy, surgery or radiotherapy. As PSCC is characterized by early lymphatic spread and imaging is inadequate for the detection of micrometastatic disease, correct and upfront surgical staging of the inguinal lymph nodes is crucial in disease management. Advanced stages of disease require multimodal management. Optimal sequencing of treatments and patient selection are still being investigated. Cisplatin-based chemotherapy regimens are the mainstay of systemic therapy for advanced PSCC, but they have poor and non-durable responses and high rates of toxic effects, indicating a need for the development of more effective and less toxic therapeutic options. Localized and advanced penile cancers and their treatment have profound physical and psychosexual effects on the quality of life of patients and survivors by altering sexual and urinary function and causing lymphoedema.

Abstract
Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections. HPV high risk (HPVHR) were HPV16,18 related with invasive penile carcinomas, and HPV low risk (HPVLR) were HPV6,11 related to anogenital warts. Male infection is usually asymptomatic that it would be explain increasing the incidence of HPV associated cancers. Identification HPV genotype is very important for predicting the development of the diseases, to be benign or malignant cancer. The objective of this study was to identify the genotype of HPV that infect men with anogential warts. This research used 12 biopsy specimens from men patient with anogenital warts at Outpatient clinic of Department Dermatology and Venereology, Dr. Soetomo General Hospital period 2016-2017. The specimens were diagnozed by pathologist and HPV gentoyping was done to detect 40 HPV genotype including HPVHR and HPVLR. The result showed that 58% (7/12) were positive for HPVLR and 42% (5/12) were positive for HPV LR/HR. The genotype HPV that infected men patient with anogenital warts is HPVLR (HPV6,11) and HPVHR (HPV18,51,52,82) with single infection of HPVLR or mutiple infection HPVLR/LR or HPVLR/HR. The infection of HPVHR would be develops to be malignant transformation. It suggested that HPV genotype needs to be checked the for the anogenital warts cases for predicting the development of the diseases.

Abstract
BACKGROUND Anogenital warts are a common human papillomavirus infection. They cause emotional distress, especially when they are in the anogenital region. Cryotherapy is a first-line treatment. Previous clinical trials and case series have reported variable results with retinoids (isotretinoin) as adjuvant therapy. OBJECTIVE To determine the safety and efficacy of low-dose oral isotretinoin as adjuvant treatment of anogenital warts. METHODS Forty-six patients with anogenital warts were randomly assigned to isotretinoin + cryotherapy (n = 23) or only cryotherapy (n = 23). Patients were allocated via an interactive web-based randomization system. Evaluators were blinded to treatments. Isotretinoin 20 mg/daily + cryotherapy or cryotherapy were prescribed for 6 weeks. Patients were followed for 4 months. Genotyping of lesions was performed before treatment started. Dermatology Life Quality Index (DLQI) and Columbia-Suicide Severity Rating Scale (C-SSRS) were measured at the beginning and end of therapy. All patients completed the study. RESULTS Both Groups had 50% clearance at the end of treatment. Recurrence in the combined group was not significantly lower than in the cryotherapy group (P = 0.59). Improvement was observed in the DLQI of all patients in both groups (P = 0.001). No suicidal intention was detected with the C-SSRS. Two patients (one in each group) had liver function test abnormalities after treatment. CONCLUSION Combined therapy showed a slight not significant efficacy for anogenital warts in Hispanic patients. Low-dose isotretinoin seems to be safe even when it is used with cryotherapy on anogenital warts. TRIAL REGISTRATION On April 25, 2019 with registration number DE19-00004, CONBIOÉTICA-19-CEI-001-20160404. Prospectively registered.

ENVIRONMENTAL RESEARCH 2021; 192:110437. [PMID: 33181134 DOI: 10.1016/j.envres.2020.110437] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 09/28/2020] [Accepted: 11/03/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Human Papillomavirus (HPV) is associated with development of oropharyngeal cancer. Aim of this review was to assess airborne transmission risk of infectious particles from HPV lesions to airway mucosa of medical staff during established ablation procedures. METHODS A systematic review of human and animal studies, published before 09/2020, relevant to airborne HPV transmission. Controlled studies reporting prevalence of HPV-associated upper airway (nasal/oral/pharyngeal) disease in staff performing ablation procedures (laser, loop electrosurgical excision [LEEP], cryosurgery) on HPV lesions were included in meta-analysis. Additionally, we aimed for a comprehensive systematic overview of studies regarding occupational risk of airborne HPV transmission and safety measures during ablation procedures. RESULTS A total of n = 30 original studies report outcomes related to HPV transmission risk in medical staff conducting ablation procedures. HPV DNA detection in ablation smoke (n = 7), matching HPV genotypes on ablated HPV lesions and face/airways of medical staff after ablation (n = 2), and evidence for infectivity of papillomavirus in ablation smoke (n = 3, animal models only) were reported. Three case reports describe occupational HPV disease of upper airway mucosa. Three controlled studies assessed warts (in CO2 laser-users only); when pooling all controls (general population, non-laser users), nasal/oral/pharyngeal lesion sites were more common amongst laser-users (OR = 5.75; 95%CI[1.55, 21.38]; p < .001). DISCUSSION Airborne HPV dispersal with matching "high-risk" HPV-genotypes in airways of medical staff after ablations (LEEP and CO2-laser) and cases of HPV-associated upper airways neoplasms based on exposure to laser and LEEP smoke are documented. Upper airway mucosa is a more common anatomical site for warts in CO2 laser users compared to controls. Simple safety measures greatly reduce HPV contamination and transmission risk.

Abstract
In the last several years, demand for transgender care from gynecologists has increased significantly. Transgender people comprise a diverse group who do not identify with the sex they were assigned at birth. Worldwide, it is estimated that 25 million people identify as transgender. Some undergo hormonal and/or surgical treatment aiming to feminize or masculinize their bodies. Cross-sex hormone treatment for transgender women-individuals assigned as male at birth who identify themselves as women-includes exogenous estrogen and/or progestin administration in combination with anti-androgens, whereas testosterone is used for transgender men-individuals whose natal sex is women but identify themselves as men. Although it is usually rare, hormone-sensitive malignancies may arise, and long-term effects remain unknown. In addition, reconstructive surgeries may include breast augmentation and vaginoplasty (creation of a vagina) for transgender women, and chest masculinization surgery (bilateral mastectomy) and metoidioplasty (lengthening of the clitoris to create a microphallus) or phalloplasty (creation of a phallus) for transgender men. Evidence relating to breast and reproductive tract cancers in the trans population is limited and insufficient to estimate cancer prevalence, and recommendations for screening and preventive care depend on the patients' hormonal and surgical status. Even less information exists regarding the sub-set of individuals with genetic predisposition for these malignancies. In this review, we aimed to summarize current recommendations for gynecologists and gynecologic oncologists regarding cancer screening and personalized cancer-risk assessment in transgender people.

Sex differences in the prevalence and determinants of HPV-related external genital lesions in young adults: a national cross-sectional survey in Brazil. BMC Infect Dis 2020; 20:683. [PMID: 32948142 PMCID: PMC7501703 DOI: 10.1186/s12879-020-05376-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Accepted: 08/26/2020] [Indexed: 01/01/2023] Open
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
Background Anogenital warts are the leading sexually transmitted infection in patients seeking care at specialized clinics. They may display a vast array of forms, according to the interaction of the virus with the host's immunity. Cellular immunity is the epithelium's main form of defense against the virus, involving an active participation of the Langerhans cells and pro-inflammatory cytokines such as TNF-α. Objective To assess the epithelial immune response of anogenital warts in males, according to the number of lesions presented. Methods This is a prospective, cross-sectional study carried out at the dermatology outpatient clinic in a tertiary hospital. We included male patients over 18 years of age without comorbidities who had anogenital condylomata and no previous treatments.In order to evaluate the local epithelial immunity, the lesions were quantified, then removed and employed in CD1a immunohistochemistry assays for assessing the morphometry and morphology of Langerhans cells; TNF-α; reaction was used for determining cytokine positivity in the epithelium. Results 48 patients were included in the study. There was no statistically significant difference as to the number of Langerhans cells, in their morphology, or the presence of TNF-α. However, patients presenting with more Langerhans cells in the lesions had cells with a star-like and dendritic morphology, whereas in those with a lower cell count had cells with a rounded morphology and no dendrites (p < 0.001). Study limitations Small number of patients analyzed. Conclusion There was no difference in epithelial immunity between patients having few or many anogenital condyloma lesions as measured by the morphology and morphometry of Langerhans cells and TNF-α; positivity. Such an assessment employing immunity markers differing from the usual ones is expected to yield useful results.

Abstract
Penile carcinoma is a relatively frequent health issue in the developing countries such as Africa, Asia and South America, usually affecting men aged between 50 and 70 years. It is a highly treatable disease in its early stages, but has serious physical and psychological consequences. Usually, penile carcinoma is located in the penile glans, in approximately half the cases, with the most frequent histological type being squamous cell carcinoma with its microscopic subtypes. A large number of risk factors have been reported for this disease, having a multifactorial etiology, HPV infection being one of the most important factors involved in its appearance. Out of the HPV DNA positive genital cancers HPV-16 is the most frequently found type in men, followed by HPV-18. The evolution of penile cancer includes two independent carcinogenic pathways, related or unrelated to HPV infection. There is limited data available in literature regarding HPV-related neoplasia, as well as on the efficacy of vaccination in men, with studies still ongoing.

Abstract
Background Flat penile lesions (FPL) in heterosexual men are thought to play a role in the transmission of HPV. We investigated the association between FPL and penile HPV, and explored determinants of FPL in men who have sex with men (MSM). Methods In 2015–2016, MSM were recruited based on HIV and penile HPV status in a previous cohort. MSM self-completed a questionnaire. Peniscopy was performed after application of acetic acid to visualize FPL. Penile physician-collected samples were tested for HPV-DNA using the highly sensitive SPF10-PCR DEIA/LiPA25 system. HPV viral load (VL) was determined using a quantitative type-specific (q)PCR targeting the L1-region. Presence of HPV and HIV, HPV VL and circumcision status were compared between MSM with and without FPL. Results We included 116 MSM, of whom 59/116 (51%) MSM were HIV-positive and 54/116 (47%) had FPL. A penile HPV infection was present in 31/54 (57%) MSM with FPL and 34/62 (55%) MSM without FPL (p = 0.8). There was no difference between MSM with and without FPL regarding presence of penile HPV infection, HPV VL, HIV status or circumcision status (p > 0.05 for all). Conclusion Among MSM in Amsterdam, we found no association between FPL and penile HPV, HPV VL, HIV status or circumcision status.

Abstract
OBJECTIVES To characterise the prevalence and distribution of human papillomavirus (HPV) types in genital warts in Xi'an, China. METHODS This prospective study was conducted in Shaanxi Provincial Institute for Skin Disease and STD Control (SPISSC) between September 2014 and April 2017. Genital wart samples were obtained from 879 patients, including 512 men and 367 women. HPV genotyping was performed by using an automatic nucleic acid hybridisation system. RESULTS Of the 879 patients with genital warts, the detectable rates of low-risk, high-risk and total HPV types were 45.4%, 34.5% and 57.8%, respectively. The detectable rate of low-risk HPV types (45.4%) was significantly higher than that of high-risk HPV types (34.5%) (χ2=21.85, p<0.01). The detectable rate of low-risk HPV types of men (52.3%) was significantly higher than that of women (35.7%) (χ2=23.90, p<0.01). The detectable rates of one HPV type infection and two and three or more HPV type coinfections were 26.1%, 17.5% and 14.2%, respectively. HPV6 (24.9%), HPV11 (17.9%), HPV52 (9.9%) and HPV16 (7.3%) were the four most common HPV types. CONCLUSIONS The results of this study suggest that low-risk HPV types are major pathogens of genital warts, but high-risk HPV type infections and multiple HPV type coinfections are also common in genital warts. HPV6, 11, 52 and 16 are the four most common HPV types in genital wart in Xi'an, China.

Abstract
Condyloma acuminata (CA), or genital warts, are benign proliferative epidermal or mucous lesions that are caused by infection with human papillomavirus (HPV), mainly the low-risk types 6 and 11. HPV variants are defined as viral sequences that share identity in the nucleotide sequence of the L1 gene greater than 98%. Based on this criterion, HPV6 and 11 variant lineages have been studied, and there are ongoing attempts to correlate these genetic variants with different clinical findings of infection. Therefore, the aims of this study were to detect variants and nucleotide alterations present in the E6 regions of HPV types 6 and 11 found in CA samples, to correlate the HPV presence with the clinical-pathological data of the patients, and to determine phylogenetic relationships with variants from other places in the world. The E6 regions of 25 HPV6 samples and 7 HPV11 samples from CA were amplified using PCR with specific primers. The products were ligated to a cloning vector and five colonies of each sample were sequenced to observe the nucleotide alterations. Twelve samples were identified as the HPV6B3 variant, presenting the mutation (guanine) G474A (adenine), and one of them also showed the mutation (thymine) T369G. The other 13 patients were positive for HPV6B1 without nucleotide alterations. In the analysis of the HPV11 samples, all patients showed the mutations T137C and (cytosine) C380T. One patient also presented the nucleotide alteration T410C. None of the mutations found in the 32 analyzed samples resulted in amino acid changes. Patient age, local occurrence, and HIV infection did not show significant association with HPV infection. Besides, the data found in this study did not show a relationship with the geographical region of isolation when compared to other data from different regions of the world. In this way, despite the nucleotide alterations found, it was not possible to observe amino acid changes and variants grouping according to geographical region.

Abstract
It is currently recognized that in addition to the major impact of human papillomavirus (HPV) infection in females, HPV causes considerable disease in men at the genitals, anal canal, and oropharynx. Specifically, genital HPV infections may progress to genital warts and penile carcinoma. Although studies concerning the natural history of HPV infections and associated neoplasias have mainly focused on women, during the last 2 decades considerable attention has been given in further understanding these infections in men. The HIM (HPV infection in men) Study, the only prospective multicenter study of male HPV natural history, consisted of a large prospective international cohort study in which men from Brazil, the United States, and Mexico were enrolled. The design and protocols of this study allowed unraveling crucial information regarding the relationship between HPV infection and clinical consequences in men, and associated risk factors at each of the anatomic sites where HPV is known to cause cancer in men.

Determinants of high-risk human papillomavirus infection in anogenital warts. Postepy Dermatol Alergol 2019; 36:76-81. [PMID: 30858783 PMCID: PMC6409869 DOI: 10.5114/ada.2019.82915] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2017] [Accepted: 12/28/2017] [Indexed: 11/17/2022] Open
Abstract
Introduction Genital warts are benign epithelial tumours caused by human papilloma viruses (HPV), and are sexually transmitted. Genotyping of genital HPV bears great clinical significance in terms of treatment planning, follow-up, and prevention strategies. Aim To evaluate the distribution of high-risk HPV infection types in patients diagnosed with anogenital warts. Material and methods A total of 66 patients with anogenital warts were enrolled. Punch biopsy samples were obtained from the lesions of each patient. After nucleic acid purification and DNA extraction, the presence of HPV DNA was ascertained using the PCR method, followed by HPV DNA genotyping. The relationship between HPV type distribution and age, gender, clinical location, and number of sexual partners was investigated. Results Genotyping was performed and HPV genome was detected in 50 tissue samples (75.8%). Low-risk genotypes predominated with a prevalence of 62.1% (42/66). The most prevalent genotypes were HPV-6 (47%), and HPV-11 (13.6%). Other types detected included HPV-18 and HPV-3. Conclusions Genotyping of HPV provides significant clinical information regarding this family of viruses that play a role in the aetiology of a variety of genital cancers, as some of these malignancies are now considered preventable due to recent development of vaccines. We believe that our results may provide guidance on future vaccination programs in our country.

Prevalence of human papillomavirus DNA and p16 INK4a in penile cancer and penile intraepithelial neoplasia: a systematic review and meta-analysis. Lancet Oncol 2018; 20:145-158. [PMID: 30573285 DOI: 10.1016/s1470-2045(18)30682-x] [Citation(s) in RCA: 135] [Impact Index Per Article: 22.5] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2018] [Revised: 08/25/2018] [Accepted: 09/04/2018] [Indexed: 12/26/2022]
Abstract
BACKGROUND Although previous meta-analyses have examined human papillomavirus (HPV) DNA prevalence in penile cancer, none, to our knowledge, have assessed pooled HPV DNA prevalence in penile intraepithelial neoplasia or p16INK4a percent positivity in penile cancer and penile intraepithelial neoplasia. Therefore, we aimed to examine the prevalence of HPV DNA and p16INK4a positivity in penile cancer and penile intraepithelial neoplasia worldwide. METHODS In this systematic review and meta-analysis, we searched PubMed, Embase, and the Cochrane Library until July 24, 2017, for English-language articles published from Jan 1, 1986, onwards reporting the prevalence of HPV DNA and p16INK4a positivity, either alone or in combination, in at least five cases of penile cancer or penile intraepithelial neoplasia. Only studies that used PCR or hybrid capture for the detection of HPV DNA and immunohistochemical staining or methylation for the detection of p16INK4a were included. Data were extracted and subsequently crosschecked, and inconsistencies were discussed to reach consensus. Using random-effects models, we estimated the pooled prevalence and 95% CI of HPV DNA and p16INK4a positivity in penile cancer and penile intraepithelial neoplasia, stratifying by histological subtype and HPV DNA or p16INK4a detection method. Type-specific prevalence of HPV6, HPV11, HPV16, HPV18, HPV31, HPV33, and HPV45 in penile cancer was estimated. FINDINGS Our searches identified 1836 non-duplicate records, of which 73 relevant papers (71 studies) were found to be eligible. The pooled HPV DNA prevalence in penile cancer (52 studies; n=4199) was 50·8% (95% CI 44·8-56·7; I2=92·6%, pheterogeneity<0·0001). A high pooled HPV DNA prevalence was seen in basaloid squamous cell carcinomas (84·0%, 95% CI 71·0-93·6; I2=48·0%, pheterogeneity=0·0197) and in warty-basaloid carcinoma (75·7%, 70·1-81·0; I2=0%, pheterogeneity=0·52). The predominant oncogenic HPV type in penile cancer was HPV16 (68·3%, 95% CI 58·9-77·1), followed by HPV6 (8·1%, 4·0-13·7) and HPV18 (6·9%, 2·9-12·4). The pooled HPV DNA prevalence in penile intraepithelial neoplasia (19 studies; n=445) was 79·8% (95% CI 69·3-88·6; I2=83·2%, pheterogeneity<0·0001). The pooled p16INK4a percent positivity in penile cancer (24 studies; n=2295) was 41·6% (95% CI 36·2-47·0; I2=80·6%, pheterogeneity<0·0001), with a high pooled p16INK4a percent positivity in HPV-related squamous cell carcinoma (85·8%, 95% CI 72·1-95·4; I2=56·4%, pheterogeneity=0·0011) as compared with non-HPV-related squamous cell carcinoma (17·1%, 7·9-29·1; I2=78·3%, pheterogeneity<0·0001). Moreover, among HPV-positive cases of penile cancer, the p16INK4a percent positivity was 79·6% (95% CI 65·7-90·7; I2=89·9%, pheterogeneity<0·0001), compared with 18·5% (9·6-29·6; I2=89·3%, pheterogeneity<0·0001) in HPV-negative penile cancers. The pooled p16INK4a percent positivity in penile intraepithelial neoplasia (six studies; n=167) was 49·5% (95% CI 18·6-80·7). INTERPRETATION A large proportion of penile cancers and penile intraepithelial neoplasias are associated with infection with HPV DNA (predominantly HPV16), emphasising the possible benefits of HPV vaccination in men and boys. FUNDING None.

Abstract
Human papillomavirus (HPV) is one of the most prevalent sexually transmitted infections. Although the research focus has been on women, men are also affected. Thus, the aim was to estimate the prevalence of HPV in men and to analyse its risk factors. A systematic review with meta-analysis was performed. The main health science databases were consulted. The search terms were was: "papilloma virus AND (prevalence OR risk factors) AND men". The final sample of studies was n = 16 and the men sample for the meta-analysis was n = 18,106. The meta-analysis revealed a prevalence of 49% (95% Confidence Interval (CI): 35⁻64%) of any type of human papillomavirus in men and 35% (95% CI: 26⁻45%) of high-risk human papillomavirus in men. The included studies showed that stable sexual habits, circumcision and condom use are protective factors against HPV. In addition, there is a certain positive association with tobacco use and the early initiation of sexual intercourse. In conclusion, the prevalence of HPV in men is high. The risk factors for HPV infection are sexual promiscuity, early sexual debut, absence of circumcision, lack of condom use and smoking. Further study in this field about the effectiveness of the vaccine and health education should be conducted.

Human papillomavirus vaccination coverage in Luxembourg - Implications of lowering and restricting target age groups. Vaccine 2018; 36:2411-2416. [PMID: 29602702 DOI: 10.1016/j.vaccine.2018.03.054] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2017] [Revised: 02/16/2018] [Accepted: 03/20/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND In Luxembourg, a national Human Papillomavirus (HPV) vaccination programme was introduced in 2008, targeting 12-17 year old girls offering a choice of bivalent or quadrivalent vaccine free of charge. In 2015, the programme was changed offering the bivalent vaccine only to 11-13 year old girls. The aim of this study was to evaluate the HPV vaccination coverage, to assess the impact of age target changes and compare vaccination coverage to other European countries. METHODS Anonymous HPV vaccination records consisting of individual vaccine doses obtained free of charge in pharmacies between 2008 and 2016 were extracted from the Luxembourgish Social Security database. Additional aggregate tables by nationality and municipality were analysed. RESULTS Of the target cohort of 39,610 girls born between 1991 and 2003 residing in Luxembourg, 24,550 (62.0%) subjects obtained at least one dose, 22,082 (55.7%) obtained at least two doses, and 17,197 (43.4%) obtained three doses of HPV vaccine. The mean age at first dose was 13.7 years during 2008-14 and 12.7 years in 2016 after the age target change. Coverage varied significantly by nationality (p < 0.0001): Portuguese (80%), former Yugoslavs (74%), Luxembourgish (54%), Belgian (52%), German (47%), French (39%) and other nationalities (51%). Coverage varied also by geographical region, with lower rates (<50%) noted in some Northern and Central areas of Luxembourg (range: 38% to 78%). CONCLUSION Overall HPV vaccination coverage in Luxembourg is moderate and varied by nationality and region. The policy changes in 2015 did not have a substantial impact except lowering age at initiating vaccination. Options to improve coverage deserve further investigation.

Abstract
BACKGROUND The infection of human papillomavirus (HPV) has been considered as the common cause of cervical cancer, which is the leading cause of cancer death in women, in Vietnam. Recently, hypermethylation at tumor suppressor genes (TSGs) has been also demonstrated to be an early epigenetic event and cofactor in human cancer, including cancer of cervix. This study evaluated the frequency of DcR1 gene promoter hyper-methylation status as well as whether did or not an association between patterns of DNA hypermethylation and high-risk HPV infection, led to risk of cervical cancer. METHODS Methylation-Specific-PCR (MSP) was performed to analyze hypermethylation status from 109 liquid-based Papanicolaou test samples, archived and admitted from the Medic Medical Center and Au Lac Clinic Laboratory, Vietnam, from 2011-2014, a kind of non-invasive samples identified whether HPV/or non-HPV, high-risk/low-risk HPV infection. RESULTS DcR1 promoter was differentially methylated in 50% cases of high-risk HPV genotype 16 and 18 infected samples. In contrast, a low frequency of hypermethylated DcR1 promoter was found in low risk HPV genotype infected sample (16.0%), and non-HPV infected sample (14.6%). A trend toward positive association was found between hypermethylation of DcR1 gene and HPV exposure was observed (P=0.0005). Moreover, the odds ratio (OR) and relative risk (RR) were found in statistical significant value (OR=5.63 (95%CI = 2.25 - 14.07, P<0.01), RR=3.31 (95%CI = 1.75 - 6.26, P<0.01)). CONCLUSION The hypermethylation of DcR1 gene promoter is a significant characteristic of high-risk HPV infected samples in Vietnamese cervical patients. The OR and RR values showed that the strong correlation between DcR1 hypermethylation and high-risk HPV infection, in which increased the risk of cervical cancer. The combination of DcR1 hypermethylation and HPV detection based biomarker could be used in noninvasive samples obtained from high-risk cancer patients, offer significant practical advantages.

Abstract
Human papillomaviruses (HPV) infected men causes continued transmission of HPV to women. The prevalence of 15 high-risk HPV strains (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 and 68) and 6 low-risk HPV strains (HPV6, 11, 42, 43, 44 and CP8304) were evaluated in 935 males with genital warts. Of the 447 (447/935, 47.8%) HPV DNA positive subjects, 230 (24.6%), 356 (38.1%) and 139 (14.9%) were infected by high-risk, low-risk and both high and low-risk HPV respectively. Of the 356 low-risk HPV infected subjects, 333(93.5%) were infected by single HPV strain; 203 (57.0%), 147 (41.3%), 24 (6.7%) and 5 (1.4%) were infected with HPV genotype 6, 11, CP8304 and 44 respectively; population with age ≤ 20 showed the highest infection rate. High-risk HPV are also highly prevalent in our patients, genotype 16, 58, 51, 39, 52 and 53 are the top five prevalent genotypes with infection rates of 27.4%, 18.7%, 14.3%, 13.9%, 12.6% and 12.6% respectively; only 68.3% subjects were sole infection; subjects with 41 ≤ age ≤ 50 showed the highest infection rate. Both high and low-risk HPV are highly prevalent in men with genital warts, its impact on women HPV control and prevention need further evaluation.

Abstract
The West African Ebola virus outbreak underlined the importance of delivering mass diagnostic capability outside the clinical or primary care setting in effectively containing public health emergencies caused by infectious disease. Yet, to date, there is no solution for reliably deploying at the point of need the gold standard diagnostic method, real time quantitative reverse transcription polymerase chain reaction (RT-qPCR), in a laboratory infrastructure-free manner. In this proof of principle work, we demonstrate direct performance of RT-qPCR on fresh blood using far-red fluorophores to resolve fluorogenic signal inhibition and controlled, rapid freeze/thawing to achieve viral genome extraction in a single reaction chamber assay. The resulting process is entirely free of manual or automated sample pre-processing, requires no microfluidics or magnetic/mechanical sample handling and thus utilizes low cost consumables. This enables a fast, laboratory infrastructure-free, minimal risk and simple standard operating procedure suited to frontline, field use. Developing this novel approach on recombinant bacteriophage and recombinant human immunodeficiency virus (HIV; Lentivirus), we demonstrate clinical utility in symptomatic EBOV patient screening using live, infectious Filoviruses and surrogate patient samples. Moreover, we evidence assay co-linearity independent of viral particle structure that may enable viral load quantification through pre-calibration, with no loss of specificity across an 8 log-linear maximum dynamic range. The resulting quantitative rapid identification (QuRapID) molecular diagnostic platform, openly accessible for assay development, meets the requirements of resource-limited countries and provides a fast response solution for mass public health screening against emerging biosecurity threats.

Abstract
The aim of the present study was to investigate the effect of the traditional Chinese medicine paiteling on the outcome of high-risk human papillomavirus (HR-HPV) infection of the cervix. A total of 321 patients were enrolled in this study and HPV subtypes were determined by the Hybribio HPV genotyping system. The patients were divided into the loop electrosurgical excision procedure (LEEP; n=82) and non-LEEP (n=239) groups, according to the cervical intraepithelial neoplasia classification. These two groups were further subdivided into the drug (paiteling) and control subgroups. Thin-prep cytology and HR-HPV tests were performed every 3 months for 1 year. In the non-LEEP group, the negative conversion rate of HR-HPV and the regression rate of the cervical lesions in drug subgroup were significantly higher compared with those in the control subgroup. In the LEEP group, the seroconversion rate of the drug subgroup, but not the regression rate of the lesions, was significantly higher compared with that in the control subgroup. The seroconversion rate of HPV16-infected patients at 12 months was 85.7%, whereas it reached 100% in all other HPV subtypes. Therefore, paiteling may accelerate the clearance of HPV infection and the regression of cervical lesions.

Abstract
Penile cancer is a rare disease in the United States, but rates are increasing, causing concern. Several risk factors have been associated with the disease, including human papillomavirus (HPV) infection. Knowledge of HPV pathogenesis has led to the development of a vaccine, which has proven instrumental in reducing the incidence of female HPV-related cancers, but results in men have yet to be elucidated. Fortunately, rates of vaccination are up-trending in both males and females in the past several years. In addition, targeted therapies are the focus of several ongoing research efforts. Some of these therapeutics are currently in use, while several are in trials. With continued patient education and research, both treatment and prevention of HPV-related pre-malignant lesions and penile cancer will likely diminish.

Human Papillomavirus (HPV) Genotypes in Condylomas, Intraepithelial Neoplasia, and Invasive Carcinoma of the Penis Using Laser Capture Microdissection (LCM)-PCR: A Study of 191 Lesions in 43 Patients.

Abstract
Laser capture microdissection-polymerase chain reaction (LCM-PCR) supported by p16 was used for the first time to demonstrate human papillomavirus (HPV) DNA in histologically specific penile lesions, which were as follows: squamous hyperplasia (12 lesions, 10 patients), flat lesions (12 lesions, 5 patients), condylomas (26 lesions, 7 patients), penile intraepithelial neoplasia (PeIN) (115 lesions, 43 patients), and invasive squamous cell carcinomas (26 lesions, 26 patients). HPV was detected by whole-tissue section and LCM-PCR. LCM proved to be more precise than whole-tissue section in assigning individual genotypes to specific lesions. HPV was negative or very infrequent in squamous hyperplasia, differentiated PeIN, and low-grade keratinizing variants of carcinomas. HPV was strongly associated with condylomas, warty/basaloid PeIN, adjacent flat lesions, and warty/basaloid carcinomas. A single HPV genotype was found in each lesion. Some condylomas and flat lesions, especially those with atypia, were preferentially associated with high-risk HPV. Unlike invasive carcinoma, in which few genotypes of HPV were involved, there were 18 HPV genotypes in PeIN, usually HPV 16 in basaloid PeIN but marked HPV heterogeneity in warty PeIN (11 different genotypes). Variable and multiple HPV genotypes were found in multicentric PeIN, whereas unicentric PeIN was usually related to a single genotype. There was a correspondence among HPV genotypes in invasive and associated PeIN. p16 was positive in the majority of HPV-positive lesions except condylomas containing LR-HPV. p16 was usually negative in squamous hyperplasia, differentiated PeIN, and low-grade keratinizing variants of squamous cell carcinomas. In summary, we demonstrated that LCM-PCR was a superior research technique for investigating HPV genotypes in intraepithelial lesions. A significant finding was the heterogeneity of HPV genotypes in PeIN and the differential association of HPV genotypes with subtypes of PeIN. The presence of atypia and high-risk HPV in condylomas and adjacent flat lesions suggests a precursor role, and the correspondence of HPV genotypes in invasive carcinomas and associated PeIN indicates a causal relation. Data presented support the bimodal hypothesis of penile cancer carcinogenesis in HPV-driven and non-HPV-driven carcinomas and justify the current WHO pathologic classification of PeIN in special subtypes.

Abstract
BACKGROUND Human papillomavirus (HPV) infection has been considered as main cause of cervical cancer. Recently, aberrant DNA methylation at tumor suppressor genes (TSGs), leading to inactivation, has also been an early epigenetic event and cofactor in cervical carcinogenesis. This study was performed to evaluate an association between the hypermethylation of p16INK4α gene's promoter and HPV exposure in non-invasive samples (liquid-based papanicolaous samples) in Vietnamese population. METHODS 109 liquid-based papanicolaous test samples were archived and admitted from the Medic Medical Center and Au Lac Clinic Laboratory, Vietnam, from 2011-2014. Methylation-Specific-PCR (MSP) was performed to analyze methylation status from the liquid-based papanicolaous test samples identified whether HPV/or non-HPV, high-risk/low-risk HPV infection. RESULTS An upward trend was observed concerning the p16INK4α hypermethylation frequency in high-risk HPV infection, counting for 55.6%, and the low methylation frequency in low-risk and non-HPV infected samples, counting for 22.9%, 8.0%, respectively. The significant correlation between candidate p16INK4α hypermethylation and HPV exposure was observed (P<0.0001). Moreover, the odds ratio (OR) and relative risk (RR) were found in statistical significant value. (OR=5.76, 95%CI: 2.36 - 14.04, P<0.01; RR=3.11, 95%CI: 1.75-5.53, P<0.01). CONCLUSION Presence of p16INK4α hypermethylation was the specific characteristic of high-risk HPV infected samples in Vietnamese population. The OR and RR values showed that the strong correlation between p16INK4α hypermethylation and high-risk HPV infection, in which increased the risk of cervical cancer. The combination of p16INK4α hyper-methylation and HPV detection based biomarker could be used in non-invasive samples obtained from high-risk cancer patients, offer significant practical advantages.

Abstract
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.

Abstract
Background Human papillomavirus type 6 (HPV-6) and HPV-11 are the etiological agents of approximately 90% of genital warts (GWs). The impact of HPV-6 genetic heterogeneity on persistence and progression to GWs remains undetermined. Methods HPV Infection in Men (HIM) Study participants who had HPV-6 genital swabs and/or GWs preceded by a viable normal genital swab were analyzed. Variants characterization was performed by polymerase chain reaction sequencing and samples classified within lineages (A, B) and sublineages (B1, B2, B3, B4, B5). Country- and age-specific analyses were conducted for individual variants; odds ratios and 95% confidence intervals for the risk of GWs according to HPV-6 variants were calculated. Results B3 variants were most prevalent. HPV-6 variants distribution differed between countries and case status. HPV-6 B1 variants prevalence was increased in GWs and genital swabs of cases compared to controls. There was difference in B1 and B3 variants detection in GW and the preceding genital swab. We observed significant association of HPV-6 B1 variants detection with GW development. Conclusions HPV-6 B1 variants are more prevalent in genital swabs that precede GW development, and confer an increased risk for GW. Further research is warranted to understand the possible involvement of B1 variants in the progression to clinically relevant lesions.

Abstract
The aims of this study were to determine the incidence of external genital lesions (EGLs), specifically histologically confirmed condyloma (genital warts) and Penile Intraepithelial Neoplasia (PeIN), and genital HPV infection progression to EGLs among healthy men aged 18-73 residing in Brazil. Subjects included 1118 men enrolled in the HPV Infection in Men (HIM) study between July 2005 and June 2009. At each visit, EGLs were biopsied and subjected to pathological evaluation. HPV status in genital swabs and biopsies was determined by Linear Array and INNO-LiPA, respectively. Age-specific EGLs incidence and the proportion and median time to EGL development were estimated. Kaplan-Meier cumulative incidence rates at 6, 12, and 24 months were determined. During follow-up, 73 men developed an incident EGL. Men could develop multiple EGLs and there were 36 men with condyloma, 27 men with lesions suggestive of condyloma, six men with PeIN, and 20 men with non-HPV lesions. HPV-positive men who developed EGLs were younger (p=0.002) than men that did not develop lesions. Among the 815 men with HPV infection, 4% progressed to EGL with the same HPV detected in the swab. During follow up, 15.7% of genital HPV-6 and HPV-11 infections progressed to condyloma (median progression time of nine months for HPV-6 versus 6.8 months for HPV-11). Approximately 1% of HPV-16 infections progressed to PeIN with a median progression time of 25 months. HPV types covered by the 4-valent HPV vaccine were detected in 82.3% and 83.3% of condyloma and PeIN, respectively. The high burden of HPV and high frequency of progression to disease underscores the need to offer HPV prophylactic vaccination to men to reduce the overall burden of infection and diseases caused by HPV.

Abstract
Background The number of patients seeking sex reassignment surgery is increasing. Approximately 1:30,000 adult males and 1: 100,000 adult females seek this procedure. Neovaginal-related disorders after sex reassignment surgery are increasingly more common. Vulvar condylomatosis is the clinical manifestation of HPV 6- and 11 infection in biological women. The same HPV-subtypes are associated with anogenital warts and penile intraepithelial neoplasia in biological men. We aim to present a case of vulvar condylomatosis after sex reassignment surgery in a male-to-female transsexual and its complete response to 5% imiquimod cream. Case We describe a case of a 19-year-old female transexual who presented one year after male to female sex reassignment surgery by inverted penile skin vaginoplasty with condyloma accuminata of the vulva. The patient had a complete response to imiquimod 5% cream 12 weeks after initiation of treatment. Conclusion Gynecologists should be prepared to treat neovaginal-related disorders in male-to-female transsexuals. Gynecologists should be prepared to treat neovaginal-related disorders in male-to-female transsexuals. Vulvar condylomatosis may arise after sex reassignment surgery. Vulvar condylomatosis after vaginoplasty could be effectively treated with 5% imiquimod cream. A multidisciplinary team is mandatory for the correct assessment of the transsexual patient.

Abstract
The purpose of this study was to assess whether the incidence of histopathologically confirmed condyloma and penile intraepithelial neoplasia (PeIN) and rates of genital HPV infection progression to these lesions differs by country (Brazil, Mexico and the U.S.). At each visit, lesions were biopsied and were categorized by pathologic diagnoses. The Linear Array genotyping method was used to identify HPV genotypes from genital swabs, while the INNO-LiPA HPV Genotyping Extra method was used for tissue specimens. Age-specific analyses were conducted for lesion incidence by country, with Kaplan-Meier estimation of cumulative incidence. The proportion of HPV infections that progressed to condyloma and PeIN, the median time to lesion development and the incidence rates were estimated by country. When comparing demographic and sexual characteristics across the three countries, sexual orientation (p = 0.008) and lifetime number of female sexual partners (p < 0.0001) were differentially associated with lesion incidence in the three countries. Condyloma incidence in Brazil and the U.S. decreased with age, while incidence remained constant across the lifespan in Mexico. There were no differences by country and age for PeIN incidence. HPV types 6 and 11 were the most common types to progress to condyloma and HPV types 16, 6 and 11 were the most common types to progress to PeIN in all three countries. The continuous risk of condyloma and PeIN across all age groups and countries in this study emphasizes the need to ensure that strong HPV immunity, such as that obtained through vaccination, is maintained across the lifespan of men.

Abstract
Background A variety of cutaneous human papillomaviruses (HPV) are detectable in genital epithelial lesions in men and non-melanoma skin cancer patients. It remains unclear whether these viruses are associated causally with skin lesions. To date, no study has prospectively examined the association between cutaneous HPV seropositivity and development of external genital lesions (EGLs) in men. Objectives To examine the association between seropositivity to cutaneous HPV types and the risk of subsequent development of EGLs. Methods A nested case-control study including 163 incident EGL cases and 352 EGL-free controls in the HPV Infection in Men (HIM) Study cohort was conducted. Cases were ascertained at each of up to 10 biannual clinical visits and verified through biopsy and pathological diagnoses. EGLs were categorized as condyloma, suggestive of condyloma, penile intraepithelial neoplasia (PeIN), and other EGLs. Archived serum specimens collected at baseline were tested for antibodies against 14 cutaneous HPV types (β types (5, 8, 12, 14, 17, 22, 23, 24, 38, and 47), α type 27, γ type 4, μ type 1, and ν type 41) using a GST L1-based multiplex serology assay. Socio-demographic and sexual behavior data were collected through a questionnaire. Using logistic regression, adjusted odds ratios (AOR) and 95% confidence intervals (CI) were estimated. Results Overall, seropositivity to ≥1 cutaneous HPV type (any-HPV) and ≥1 β types (any-β) was 58.3% and 37.5% among other EGL cases, 71.6% and 46.8% among condyloma, 66.8% and 50.0% among PeIN, and 71.9% and 38.4% among controls, respectively. Type-specific seropositivity was most common for ɤ-HPV 4, μ-HPV 1, and β-HPV 8. No statistically significant association was observed between any-HPV, any-β, and type-specific HPV seropositivity and subsequent development of EGLs across all pathological diagnoses. Conclusions Overall, seropositivity to cutaneous HPV was common among men; however, it appears that cutaneous HPV is not associated with the development of genital lesions in men.

Abstract
Answer questions and earn CME/CNE Squamous cell carcinoma (SCC) of the penis is a rare malignancy in the United States, with a significantly higher incidence-up to 20 to 30 times greater-in areas of Africa and South America. This can be explained in part by the significantly greater prevalence of sexually transmitted diseases among high-risk males often having unprotected sex with multiple sexual partners. Human papillomavirus (HPV) has been implicated as the infectious pathway by which several these penile neoplasms originate from precursor lesions. In this regard, a fundamental understanding of HPV in penile carcinogenesis can have meaningful implications in understanding 1) the diagnosis of HPV-related precursor penile lesions, 2) targeting HPV-specific molecular pathways, and 3) cancer prevention. Using vaccination programs not only may improve patient outcomes but also may minimize the need for highly aggressive and often debilitating surgical resection.

Abstract
BACKGROUND Cutaneous human papillomaviruses (HPVs) increase the risk of non-melanoma skin cancer in sun-exposed skin. We examined the role of beta-HPV in the development of male external genital lesions (EGLs), a sun-unexposed site. METHODS In this nested case-control study (67 men with pathologically-confirmed EGLs and 134 controls), exfoliated cells collected from the surface of lesions and normal genital skin 0, 6, and 12 months preceding EGL development were tested for beta-HPV DNA using a type-specific multiplex genotyping assay. Beta-HPV prevalence was estimated and conditional logistic regression was used to evaluate the association with condyloma, the most common EGL. RESULTS While beta-HPV prevalence among controls remained stable, the prevalence among cases was lowest on the surface of lesion. Detecting beta-HPV on the normal genital skin was not associated with the presence or development of condyloma. CONCLUSIONS Cutaneous beta-HPV does not appear to be contributing to pathogenesis in male genital skin.

Abstract
Human Papillomavirus is agent of the most common sexually transmitted disease which is able to infect mucosal and cutaneous membranes of the anogenital region, upper aerodigestive tract, and other head and neck mucosal regions. Although mainly HPV infection can be asymptomatic and transient, it may persist and give rise to various lesions such as warts, condyloma dysplasia and cancers depending on low or high risk type of HPV infection. Moreover, growing recent evidence suggests a role of this virus in male and female fertility. To date no effective prevention, test, treatment and control strategies are provided for people in developing countries despite the reported high incidence of HPV both in women and men. This paper reviews the more recent literature about HPV infection highlighting epidemiology, related pathologies and possible fertility effects of HPV in male and female with particular attention to the Mozambique context.

Abstract
BACKGROUND Little is known about the characteristics of high-risk papillomavirus (HR-HPV) infection in men. The aims of this cross-sectional study were: (a) to investigate HR-HPV prevalence and genotype distribution in men, sexual partners of women presenting with high-grade cervical intraepithelial neoplasia (HG-CIN), according to epidemiological characteristics, and (b) to assess type-specific concordance between partners. METHODS A total of 125 men were recruited within the first 6 months after HG-CIN diagnosis of their partner. Samples from the coronal sulcus, glans penis shaft, and scrotum were tested with linear array HPV genotyping assay (Roche Diagnostics, Mannheim, Germany). Type-specific concordance within 120 couples was studied. Epidemiological factors were evaluated by multivariate logistic regression analysis. SPSS 19 (IBM, Chicago, USA). RESULTS The prevalence of HR-HPV infection in males was 50.4% (63/125). HPV16/53/52/51/66/31 were the most frequent genotypes (24/10.4/9.6/8.8/8/7.2%, respectively). Current smoking was associated with an increased risk for HR-HPV infection in men (38.2% (21/55) vs 60% (42/70), OR 2.4, p=0.025). Among 60 infected couples, 62% shared at least one genotype: 41.7% couples were concordantly HPV16 positive and 18.3% were HPV16 negative (kappa value: 0.21). The proportion of women with the same genotype as their male partner was higher than the proportion of men sharing the same genotype as their female partner: 58.7% (37/63) vs 30.8% (37/120), p<0.0001. CONCLUSIONS Sexual partners of women with HG-CIN are a significant reservoir and vector of HPV infection, a fact that could contribute to making viral clearance more difficult to achieve in their partners after treatment of their HG-CIN lesions.

Abstract
Background Protection from naturally acquired human papillomavirus (HPV) antibodies may influence HPV infection across the lifespan. This study describes seroconversion rates following genital, anal, and oral HPV 6/11/16/18 infections in men and examines differences by HPV type and anatomic site. Methods Men with HPV 6/11/16/18 infections who were seronegative for those genotypes at the time of DNA detection were selected from the HPV Infection in Men (HIM) Study. Sera specimens collected ≤36 months after detection were analyzed for HPV 6/11/16/18 antibodies using a virus-like particle-based ELISA. Time to seroconversion was separately assessed for each anatomic site, stratified by HPV type. Results Seroconversion to ≥1 HPV type (6/11/16/18) in this sub-cohort (N=384) varied by anatomic site, with 6.3%, 18.9%, and 0.0% seroconverting following anal, genital, and oral HPV infection, respectively. Regardless of anatomic site, seroconversion was highest for HPV 6 (19.3%). Overall, seroconversion was highest following anal HPV 6 infection (69.2%). HPV persistence was the only factor found to influence seroconversion. Conclusions Low seroconversion rates following HPV infection leave men susceptible to recurrent infections that can progress to HPV-related cancers. This emphasizes the need for HPV vaccination in men to ensure immune protection against new HPV infections and subsequent disease.

Abstract
Formalin-fixed, paraffin-embedded (FFPE) tissue specimens stored in pathology departments worldwide are an invaluable source for diagnostic purposes when fresh clinical material is unavailable as well as for retrospective molecular and epidemiological studies, especially when dealing with rare clinical conditions for which prospective collection is not feasible. Accurate detection of HPV infection in these specimens is particularly challenging because nucleic acids are often degraded and therefore, not suitable for amplification of larger fragments of the viral genome or viral gene transcripts. This review provides a brief summary of molecular methods for detecting alpha-HPV DNA/RNA in FFPE tissue specimens. We specifically address the key procedural and environmental factors that have the greatest impact on the quality of nucleic acids extracted from FFPE tissue specimens, and describe some solutions that can be used to increase their integrity and/or amplifiability. Moreover, commonly used methods for HPV DNA/RNA detection in FFPE tissue specimens are presented and discussed, focusing on studies using polymerase chain reaction as an HPV detection method and published after 1999. Finally, we briefly summarize our 22 years of experience with HPV detection in FFPE tissue specimens.

Abstract
BACKGROUND Human papillomavirus (HPV) causes two types of external genital lesions (EGLs) in men: genital warts (condyloma) and penile intraepithelial neoplasia (PeIN). OBJECTIVE The purpose of this study was to describe genital HPV progression to a histopathologically confirmed HPV-related EGL. DESIGN, SETTING, AND PARTICIPANTS A prospective analysis nested within the HPV Infection in Men (HIM) study was conducted among 3033 men. At each visit, visually distinct EGLs were biopsied; the biopsy specimens were subjected to pathologic evaluation and categorized by pathologic diagnoses. Genital swabs and biopsies were used to identify HPV types using the Linear Array genotyping method for swabs and INNO-LiPA for biopsy specimens. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS EGL incidence was determined among 1788 HPV-positive men, and cumulative incidence rates at 6, 12, and 24 mo were estimated. The proportion of HPV infections that progressed to EGL was also calculated, along with median time to EGL development. RESULTS AND LIMITATIONS Among 1788 HPV-positive men, 92 developed an incident EGL during follow-up (9 PeIN and 86 condyloma). During the first 12 mo of follow-up, 16% of men with a genital HPV 6 infection developed an HPV 6-positive condyloma, and 22% of genital HPV 11 infections progressed to an HPV 11-positive condyloma. During the first 12 mo of follow-up, 0.5% of men with a genital HPV 16 infection developed an HPV 16-positive PeIN. Although we expected PeIN to be a rare event, the sample size for PeIN (n=10) limited the types of analyses that could be performed. CONCLUSIONS Most EGLs develop following infection with HPV 6, 11, or 16, all of which could be prevented with the 4-valent HPV vaccine. PATIENT SUMMARY In this study, we looked at genital human papillomavirus (HPV) infections that can cause lesions in men. The HPV that we detected within the lesions could be prevented by a vaccine.
