    The genomes of two novel human papillomavirus (HPV) types, HPV68 and HPV70, were cloned from a low-grade cervical intraepithelial neoplasia and a vulvar papilloma, respectively, and partially sequenced. Both types are related to HPV39, a potentially oncogenic virus. HPV68 and HPV70 were also detected in genital intraepithelial neoplasia from three patients and one patient, respectively. Comparison with sequence data in the literature indicates that the subgenomic ME180-HPV DNA fragment, clone...

    The HPV infection in men (HIM) study examines the natural history of genital HPV infection in men. Genotyping methods used in this study identify 37 α-HPV types; however, the viral type could not be identified in approximately 22% of male genital specimens that were HPV PCR positive. Our aim was to genotype HPV-unclassified specimens by sequencing PGMY09/11, GP5+/6+ or FAP59/64 PCR products. Using this approach we were able to detect 86 unique HPV types among 508 of 931 specimens analyzed. We report for the first time the presence of a broad range of α-, β- and γ-HPV at the male genitals. PMID:23722104

    Full Text Available 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.

    Objective: Persistence of HPV infection is the true cause of cervical disorders. It is reported that competition may exist among HPV genotypes for colonization. This survey was designed to establish the multiple HPV genotype status in our community and the probability of multiple HPV infections involvement. Methods: All multiple HPV infections were selected for investigation in women suffering from genital infections referred to private laboratories in Tehran, Iran. A total of 160 multi HPV positive specimens from cervical scraping were identified by the HPV genotyping methods, "INNO-LiPA and Geno Array". Result: In present study, HPV 6 (LR), 16 (HR), 53 (pHR), 31 (HR) and 11 (LR) were included in 48.8% of detected infections as the most five dominant genotypes. HPV 16 was detected at the highest rate with genotypes 53, 31 and 52, while HPV 53 appeared linked with HPV 16, 51 and 56 in concurrent infections. It appears that HPV 16 and 53 may have significant tendencies to associate with each other rather than with other genotypes. Analysis of the data revealed there may be some synergistic interactions with a few particular genotypes such as "HPV 53". Conclusion: Multiple HPV genotypes appear more likely to be linked with development of cervical abnormalities especially in patients with genital infections. Since, there are various patterns of dominant HPV genotypes in different regions of world, more investigations of this type should be performed for careHPV programs in individual countries.

    Human papillomavirus (HPV) is a carcinogenic agent responsible for tumor development in many sexually involved tissues. We present a survey on the prevalence of HPV infection in a risk population for sexually transmitted infections (STIs). The studied population was formed by 125 STI clinic attendees, who took part in a screening program on STIs. To be included in the study, the patients had to show no overt clinical signs of HPV infection. Genital (cervical in women, urethral in men), anal, and oral samples were collected with ThinPrep liquid based cytology preparation system. Overall, of the screened population, 56% proved positive for genital HPV, 37% for oral HPV, and 42% for anal HPV infection. Our data indicate that in STI patients, HPV infection is more prevalent, than previously estimated. Further studies are needed to better understand the epidemiological burden of HPV in sexually involved tissues, especially in the oral mucosa. © 2016 Wiley Periodicals, Inc.

    Information on HPV knowledge in patients with genital warts is scarse as is the information on factors related to the impact on self-esteem and sex life among them. We conducted a cross-sectional study in adult patients with a clinical diagnosis of genital warts (GW) attending a major private out-patient clinic in Bogotá, Colombia. Patients underwent biopsy for pathological diagnosis, HPV-DNA testing and completed a questionnaire assessing HPV knowledge, and the consequences of GW on self-esteem and sexual life. Differences in proportions were assessed with a chi2 test. 106 men and 155 women had pathologic confirmation of GW. 51% of subjects had heard of HPV before consultation coming mainly from the media (82%). Less than half of the participants knew that HPV could be transmitted through non-penetrant sexual intercourse and only two thirds acknowledged HPV vaccine as a preventive measure against HPV infection. Impact on self-esteem was higher among women than men (90.3% vs 60.4%, [p p = 0.05]). We found a low awareness of HPV and low knowledge on the vaccine as a preventive measure for associated diseases even in patients suffering from genital warts, highlighting the need for communication and education on HPV. Greater impact on self-esteem in women might reflect higher health consciousness among Latin American women.

    Photodynamic therapy (PDT) has demonstrated good clinical cure rates and low recurrence rates in the treatment of genital warts. Human papillomavirus (HPV) genotypes and viral load assays can reflect the status of persistent or latent infection and serve as a predictor of infection clearance. Specimens from 41 patients with HPV infection were obtained, and the HPV genotypes and viral load were analyzed using real-time polymerase chain reaction (PCR) assays. Traditional treatment, such as radiofrequency, microwave, or surgical therapy, was used to remove the visible lesions, and then PDT treatment was performed every week. HPV DNA testing was performed at every patient visit and the frequency of PDT treatment was determined by changes in HPV viral loads. HPV viral loads decreased significantly after PDT treatment. There were significant differences in HPV viral loads between pretherapy and three or six rounds of PDT treatment. Significant differences were also observed between single and multiple type HPV infection after six rounds of PDT treatment. Patients with single type HPV infection had significantly higher rates of negative HPV DNA test results, as compared with patients with multiple infections after six rounds of PDT treatment; however, there was no difference in recurrence rates between the two groups. Dynamic monitoring of HPV genotypes and viral loads can be used to guide PDT treatment and indicate PDT treatment efficacy in eliminating HPV. Copyright © 2017 Elsevier B.V. All rights reserved.

    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.

    Background and Aim: Human papilloma viruses (HPVs) are small DNA tumor viruses that infect epithelial tissues and cause warts. One of the viral genes responsible for HPV's oncogenic activity is E6 which is known to inactivate the cellular p53 tumor suppressor gene. We aim to detect the presence of HPV infection and its different types in human warts, and to identify the relation between HPV and p53 expression in skin and genital lesions. Patients and Methods: We studied markers of HPV infection in overall of 30 patients (20 with common warts, and 10 with genital warts). Also, 30 normal skin samples were taken from each patient as a normal control. Detection of HPV was done using polymerase chain reaction (PCR), and HPV typing was performed using LiPA (Line immuno Probe Assay). In addition, all skin lesions were examined by immunohistochemistry for p53 expression. Results: In patients with common warts, HPV DNA was found in 4/20 (20%) of cases which was of HPV types 11, 31, 6, 33 (p=0.28). Also, P53 expression was found in 4/20 (20%) of cases (p=0.26). No single patient showed reactivity of both HPV and p53 expression. In patients with genital warts, however, HPV DNA was found in 6/10 (60%) of cases. Of these, 5 cases were positive for HPV type 6 and one case had HPV type 11. Three patients (30%) were positive for p53, and two of them (66%) were positive for both HPV and p53. In the normal skin control, 2/30 (6.6%) were positive for HPV DNA which were of types 5, and 31. Conclusions: We conclude that; (1) Prevalence rate of HPV infection in warts is higher than those of normal control group, and Egyptian patients with genital warts had higher prevalence rate of HPV than those with common warts, (2) In Egypt, HPV types 6, and 11 are the most prevalent genotypes associated with genital warts and HPV types 6, 11, 31, and 33 are associated with common warts, (3) There was no definite relation between p53 expression and HPV detection, (4) Also, there was no association

    Human papillomavirus (HPV) is the causative agent of nearly all cervical cancer cases as well as a substantial proportion of anal, vulvar, vaginal, penile and oropharyngeal cancers, making it responsible for approximately 5% of the global cancer burden. The first-generation HPV vaccines that is, quadrivalent HPV type 6/11/16/18 vaccine and bivalent HPV type 16/18 vaccine were licensed in 2006 and 2007, respectively. A second-generation 9-valent HPV type 6/11/16/18/31/33/45/52/58 vaccine with broader cancer coverage was initiated even before the first vaccines were approved. By preventing HPV infection and disease due to HPV31/33/45/52/58, the 9vHPV vaccine has the potential to increase prevention of cervical cancer from 70 to 90%. In addition, the 9vHPV vaccine has the potential to prevent 85-95% of HPV-related vulvar, vaginal and anal cancers. Overall, the 9vHPV vaccine addresses a significant unmet medical need, although further health economics and implementation research is needed.

    Full Text Available Introduction: A second generation HPV vaccine has been developed for the prevention of anogenital cancers and precancerous lesions of the cervix, vulva, vagina, anus and of genital warts due to nine HPV types.We estimated the annual burden of these diseases attributable to the nine HPV types compared to HPV types from first generation vaccines in women and men in Europe. Material and methods: Incidence rates from the IARC database, cancer registries, the literature and Eurostat population data were used.The burden attributable to the HPV types targeted by both vaccines was estimated by applying the relative contribution of the respective HPV types from epidemiological studies. Results: In 2013, the number of new anogenital HPV-attributable cancers was 44,480 with 39,494 of these cases related to second vs. 33,285 to first generation vaccine types.Among the 284,373 to 541,621 new HPV-attributable anogenital precancerous lesions 235,364–448,423 and 135,025–256,830 were estimated to be related to second and first generation vaccine types, respectively.The annual number of new genital warts was 753,608–935,318, with 90% related to HPV6/11. Conclusions: These data demonstrate how the large public health impact that was achieved by the first generation HPV vaccines could be further increased by second generation vaccines.

    Full Text Available The Human papillomaviruses (HPV vaccine induces a herd immunity effect in genital warts when a large number of the population is vaccinated. This aspect should be taken into account when devising new vaccine strategies, like vaccination at older ages or male vaccination. Therefore, it is important to develop mathematical models with good predictive capacities. We devised a sexual contact network that was calibrated to simulate the Spanish epidemiology of different HPV genotypes. Through this model, we simulated the scenario that occurred in Australia in 2007, where 12–13 year-old girls were vaccinated with a three-dose schedule of a vaccine containing genotypes 6 and 11, which protect against genital warts, and also a catch-up program in women up to 26 years of age. Vaccine coverage were 73 % in girls with three doses and with coverage rates decreasing with age until 52 % for 20–26 year-olds. A fast 59 % reduction in the genital warts diagnoses occurred in the model in the first years after the start of the program, similar to what was described in the literature.

    Full Text Available Abstract Background We investigated the role of infection with genital and cutaneous human papillomavirus types (HPV in the aetiology of ocular surface squamous neoplasia (which includes both conjunctival intraepithelial neoplasia (CIN and carcinoma using data and biological material collected as part of a case-control study in Uganda. Results Among 81 cases, the prevalence of genital and cutaneous HPV types in tumour tissue did not differ significantly by histological grade of the lesion. The prevalence of genital HPV types did not differ significantly between cases and controls (both 38%; Odds ratio [OR] 1.0, 95% confidence interval [CI] 0.4–2.7, p = 1.0. The prevalence of cutaneous HPV types was 22% (18/81 among cases and 3% (1/29 among controls (OR 8.0, 95% CI 1.0–169, p = 0.04. Conclusion We find no evidence of an association between genital HPV types and ocular surface squamous neoplasia. The prevalence of cutaneous HPV was significantly higher among cases as compared to controls. Although consistent with results from two other case-control studies, the relatively low prevalence of cutaneous HPV types among cases (which does not differ by histological grade of tumour indicates that there remains considerable uncertainty about a role for cutaneous HPV in the aetiology of this tumour.

    Human papillomavirus (HPV) is the most important pathogenetic factor of intraepithelial neoplasias of the lower genital tract. HPV-DNA and mRNA tests are applied for the management of epithelial dysplasias. The aims of this multicentric retrospective study were to compare the 2 molecular tests before the onset of metachronous intraepithelial lesions and to analyze the different characteristics between synchronous and metachronous lesions and their relationship to the pathologic mechanisms. The study concerns 55 cases of multiple intraepithelial neoplasias of the lower genital tract. Clinical features of patients with synchronous and metachronous lesions were analyzed. During a 3-year follow-up, HPV-DNA and mRNA tests were performed every 6 months after treatment of the initial lesion. HPV-DNA and mRNA results were analyzed 12 and 6 months before, at time of the onset of the metachronous lesion, and 6 months after its treatment. We observed 31 synchronous lesions and 24 metachronous lesions. Immunodeficiency and multiple genotypes were associated with the synchronous lesions (p = .04 and p = .02, respectively). During the follow-up, positive DNA and mRNA tests increased before the appearance of the metachronous lesion and decreased 6 months after; mRNA test was significantly better than the DNA test 6 months before the appearance of the lesion (p = .04) and at the time of its appearance (p = .02). Our results support the hypothesis that a positive HPV-mRNA test could be a marker of persistent infection and a risk factor for the onset of metachronous lesions.

    The performance characteristics of the INNO-LiPA Genotyping v2 test for human papillomavirus (HPV) identification were assessed by comparing results with those obtained by PCR product sequencing after subcloning, in genital samples from 20 highly sexually exposed African women. The INNO-LiPA HPV Genotyping v2 test identified more HPV types than subcloning/sequencing (56 versus 37, respectively). Overall, 86.5% (32/37) of the HPV types identified by subcloning/sequencing were identified by the INNO-LiPA HPV Genotyping v2 test, whereas 57.1% (32/56) of the HPV types identified by the INNO-LiPA HPV Genotyping v2 test were identified by subcloning/sequencing. Of the 20 clinical samples tested, 7 had identical types detected under both methods and a further 11 had more types detected under INNO-LiPA HPV Genotyping v2 than subcloning/sequencing. Of the remaining two samples, the same number of types were detected under both methods, but different types were detected. INNO-LiPA HPV Genotyping v2 test appears as a valid method for identifying HPV subtypes in women with multiple HPV infection.

    Current studies indicate a strong correlation between specific morphological changes and the presence of certain HPV strains in precancerous squamous epithelium of the cervix, vulva and vagina. HPV type 16 is the most commonly detected HPV type in cervical lesions in our experience, and 85% of these lesions exhibit some morphological features associated with aneuploid epithelium (CIN). However, over 50% of these lesions containing HPV 16 DNA exhibit, in addition, foci of epithelium indistinguishable from condyloma, although in our experience, only one HPV type(16) is detected in the majority of these lesions. DNA-DNA in situ hybridization analysis of these lesions containing HPV 16 DNA has demonstrated nucleic acids in areas resembling both condyloma and CIN, with the greatest concentration in mature cells containing cytoplasmic maturation. Ten percent of lesions containing HPV 16 produce detectable capsid antigens, and we have confirmed the presence of these antigens in the same areas which hybridize in-situ for HPV DNA. Recent studies using biotin and S-35 labeled RNa probes constructed in GEM-1 vectors indicate that early HPV genes are expressed primarily in the upper (more mature) regions of the neoplastic epithelium. Thus maturation appears to exert a positive influence on a variety of HPV functions in neoplastic epithelium, including DNA replication, early and late gene expression. It is possible that patterns of gene expression may vary between lesions associated with different HPV types or different morphologies. This possibility is being explored

    Human papillomavirus (HPV) infection has been firmly established as a central and necessary cause of invasive cervical cancer and it has been etiologically linked to other anogenital (vulva, vagina, anus and penis) and head and neck cancers, particularly oropharyngeal. Although being rare, the incidence of some of these cancers in some countries has increased in the last decades. HPV-related anogenital tumors share many risk factors with cervical cancer. The HPV aetiological contribution differs in each anatomical location reflecting differences in the natural history and viral tissue tropism. The highest prevalence of HPV DNA in cancers other than cervix has been described for anal, followed by vagina, penile and vulvar cancers. HPV16 has been described as the most common type detected in all cancer sites with different contributions being the highest in anal carcinoma (around 80% of HPV DNA positive anal cancers) and the lowest in vaginal cancers with a contribution similar to that found in cervical cancers (around 60%). Current HPV vaccines have already demonstrated their efficacy in preventing anogenital pre-neoplastic lesions caused by vaccine HPV types. HPV-based prevention tools like HPV vaccination and to a lesser extend screening (e.g. for anal cancer) can be useful measures for reducing the burden of these anogenital cancers.

The 9vHPV was developed from the qHPV and includes five additional HPV types that should increase the level of protection toward HPV-related cancers. Efficacy and/or immunogenicity of 9vHPV has been assessed in eight clinical studies. The 9vHPV vaccine induced a very robust immune response against all vaccine types, with seroconversion rates close to 100%. The safety profile of 9vHPV is comparable to that of qHPV. Local reactions, especially swelling, have been more frequently reported after 9vHPV than qHPV, and this slightly increases when the 9vHPV is coadministered with other vaccines. The additional coverage offered by the 9vHPV may prevent a significant proportion of HPV-related cancers (variable between 8% and 18% depending on the local distribution of high-risk HPV types in the population.

    Full Text Available Human Papilomaviruses (HPV are a group of viruses associated with benign and malignant lesions of cutaneous and mucosal epithelia. Some "high risk" HPV types, especially HPV 16 and 18, are strongly correlated with cervical and anogenital cancers and are also related to the genesis of oral squamous cell carcinomas (OSCC. The aim of this work was to investigate the incidence of HPV infection in 40 paraffin-embedded or fresh specimens of OSCC, using PCR amplification of the viral DNA. Literature based primers (GP5+/GP6+ were used in order to amplify HPV DNA from the L1 gene, present in more than 22 types of HPV. A condyloma case with HPV 16 and 18 detected by in situ hybridization was used as a positive control. Amplification of HPV was observed only in the positive control. No squamous cell carcinoma cases showed DNA viral amplification. Absence of HPV DNA amplification by PCR in the analyzed specimens of OSCCs suggests that this virus not always plays a role in the carcinogenesis process. Discrepancy with some studies found in the literature may be related to methodology or population differences.O papilomavírus humano (HPV constitui um grupo de vírus associados com lesões benignas e malignas do epitélio da pele e das mucosas. Alguns tipos de HPV, ditos oncogênicos, especialmente os HPVs 16 e 18, estão fortemente correlacionados com os cânceres cervical e anogenital, e também têm sido implicados na gênese do carcinoma epidermóide de boca. O objetivo deste estudo foi investigar a incidência de infecção pelo HPV, em 40 casos de carcinoma epidermóide de boca emblocados ou não em parafina, utilizando-se para isso a amplificação do DNA viral por PCR. Foram utilizados os iniciadores GP5+/GP6+, que amplificam parte da região L1 do vírus, comum a mais de 22 tipos de HPVs. Como controle positivo para as reações, foi utilizado um caso de condiloma, o qual foi positivo para os HPVs 16 e 18 na hibridização in situ. A amplifica

    Full Text Available Abstract Cervical cancer is the fourth most common cancer in women worldwide, and the main cause is Human Papillomavirus (HPV infection. HPV vaccines have had dramatic impacts on the prevalence of targeted HPV types (6,11,16 and 18, genital warts and precancerous cervical lesions. The World Health Organization (WHO and Centers for Disease Control and Prevention (CDC have confirmed the safety of HPV vaccines after >250 million doses were administered worldwide. WHO approved the two-dose-schedule of HPV vaccines in females younger than 15 years of age, with ≥6 month intervals. Extension of vaccination to men could further reduce the population prevalence of HPV and provide direct protection of men against genital warts and anal, penile and oropharyngeal cancers. The nine-valent HPV vaccine has demonstrated equivalent protection against the four types in the quadrivalent vaccine and high efficacy against the next five commonest causes of cervical cancer (HPV types 31,33,45,52 and 58. The Advisory Committee on Immunization Practices (ACIP recommends the nine-valent vaccine and it has been approved by the FDA in 2014 for both genders between 11–12 years of age.

    Full Text Available While much is known about the natural history of cervical human papillomavirus (HPV infection and its consequences, including cervical intraepithelial neoplasia and cervical cancer, relatively little is known about the natural history of anogenital HPV infection and diseases in men. In part this reflects difficulties in penile sampling and visual assessment of penile lesions. Anal HPV infection and disease also remain poorly understood. Although HPV is transmitted sexually and infects the genitals of both sexes, the cervix remains biologically more vulnerable to malignant transformation than does the penis or anus in men. An understanding of male HPV infection is therefore important in terms of reducing transmission of HPV to women and improving women's health. However, it is also important due to the burden of disease in men, who may develop both penile and anal cancer, particularly among HIV-positive men who have sex with men. Improved sampling techniques of the male genitalia and cohort studies in progress should provide important information on the natural history of anogenital HPV infection and disease in men, including risk factors for HPV acquisition and transmission. The impact of HPV vaccination in women on male anogenital HPV infection will also need to be assessed.

Dos 155 artigos identificados, 82 permaneceram após leitura de título e resumo e foram submetidos à leitura integral, sendo selecionados 14 artigos. RESULTADOS: Os artigos sobre o tema foram publicados entre 1989 e 2008. Os 14 artigos representaram estudos de quatro regiões brasileiras (Sudeste 43%, Sul 21,4%, Nordeste 21,4% e Norte 7,1%. Nove artigos relatavam estudos transversais. Em oito utilizaram-se técnicas moleculares para tipagem do HPV e em sete deles utilizou-se captura híbrida para detecção do HPV. As populações estudadas variaram de 49 a 2.329 mulheres. A prevalência geral de infecção do colo do útero pelo HPV variou entre 13,7% e 54,3%, e para as mulheres com citologia normal, variou entre 10,4% e 24,5%. Quatro estudos relataram os tipos de HPV mais freqüentes, segundo resultado de citologia. CONCLUSÕES: As técnicas de citologia disponíveis resultam em diversas classificações e estimativas de prevalência do HPV. Contudo, considerando separadamente os estudos segundo a técnica utilizada, observa-se que a prevalência do HPV tem aumentado. O HPV16 foi o tipo mais freqüente entre as mulheres, independentemente do resultado de citologia. A concentração dos estudos na região Sudeste do País, especialmente nas regiões metropolitanas, mostra que investigações adicionais serão necessárias para aumentar a abrangência das informações disponíveis sobre as mulheres brasileiras.OBJETIVO: Analizar la prevalencia de infección por el virus de papiloma humano en mujeres en Brasil.

    To express HPV6bL2deltaN360E7E6 fusion protein in E. coli and preliminarily evaluate its immune effect. Three HPV6b gene fragments, which were L2(1-360 bp), E7 and E6, were fused by overlapping PCR, then were inserted into a prokaryotic expression vector and expressed in E. coli. C57BL/6 mice were immunized with purified fusion protein plus Al (OH)3 and/or CpG adjuvants through intramuscular route, the cellular and humoral immune responses were detected by IFN-gamma ELISPOT and ELISA respectively. Protein plus CpG adjuvant could induce the strongest cellular immune response to E7 and E6, high antibody titer against L2 could be detected in all immunized groups but there were no significant difference among these groups. HPV6bL2deltaN360E7E6 gene was successfully cloned into pQE30 vector and expressed in E. coli, the fusion protein was also purified and proved that could induce strong cellular and humoral immune responses with appropriate adjuvant in C57BL/ 6 mice and could be used for future research.

    Squamous cell carcinoma (SCC) is the most common skin cancer diagnosed in solid organ transplant recipients (OTRs) and confers significant mortality. The development of SCC in the genital region is elevated in nonwhite OTRs. Viral induction, specifically human papillomavirus (HPV), is hypothesized to play a role in the pathophysiology of these lesions. To assess the prevalence and types of genital lesions observed in OTRs. This retrospective review included 496 OTRs who underwent full skin examination from November 1, 2011, to April 28, 2017, at an academic referral center. The review was divided into 2 distinct periods before a change in clinical management that took effect on February 1, 2016 (era 1) and after that change (era 2). Patient awareness of genital lesions was assessed. All lesions clinically suggestive of malignant tumors were biopsied and underwent HPV polymerase chain reaction typing. Number and types of genital lesions, proportion of malignant tumors positive for HPV, and patients cognizant of genital lesions. Of the total 496 OTRs, 376 OTRs were evaluated during era 1 (mean [SD] age, 60 years; age range, 32-94 years; 45 [65.2%] male; 164 [43.6%] white) and 120 OTRs were evaluated during era 2 of the study (mean age, 56 years; age range, 22-79 years; 76 [63.3%] male; 30 [25.0%] white). Overall, 111 of the 120 OTRs (92.5%) denied the presence of genital lesions during the history-taking portion of the medical examination. Genital lesions were found in 53 OTRs (44.2%), cutaneous malignant tumors (basal cell carcinoma and SCC in situ) in 6 (5.0%), genital SCC in situ in 3 (4.2%), and condyloma in 29 (24.2%). Eight of the 12 SCC in situ lesions (66.7%) were positive for high-risk HPV. Seven tested positive for HPV-16 and HPV-18, and 1 tested positive for high-risk HPV DNA but could not be further specified. Genital lesions in OTRs are common, but awareness is low. All OTRs should undergo thorough inspection of genital skin as a part of routine

    Human papillomavirus (HPV) type 16 is strongly implicated in the development of progressive neoplasias of the uterine cervix. Its oncogenic potential is decisively determined by the activity of the early gene products E6 and E7. To look for changes in the expression of these genes during tumour progression we cloned subgenomic fragments of HPV16 into RNA expression vectors, which allowed the generation of 35S-labelled riboprobes specific for distinct mRNA classes. Four constructs were made to differentiate between transcripts starting upstream of the E6 ORF or the E1 ORF, and one probe was specific for unspliced E6/E7 region transcripts. Five other constructs were used to identify transcripts covering the E1, E2, E4, L1 and L2 regions. With the help of these constructs, we analyzed by in situ hybridization 2 low-grade intraepithelial neoplasias of the vulva, 1 high-grade neoplasia of the cervix as well as 4 vulvar and 3 cervical carcinomas. Transcripts from the E1, E2, E4, L1 and L2 region that were consistently detected in the differentiated layers of benign lesions were variably expressed in precancers and carcinomas. None of the investigated cases revealed detectable amounts of unspliced E6/E7 transcripts with a coding potential for a full-length E6 protein. In benign lesions, the E7 transcripts were confined to isolated nuclei of differentiated cells, whereas high-grade lesions and invasive cancers showed elevated levels of equally distributed E7-specific signals in the cytoplasm of all tumour cells. The most abundant transcripts observed in intraepithelial neoplasias and in invasive cancers appear to initiate within ORF E7 and therefore have no coding potential for full-length E6 and E7 proteins. Our data show that the actual level of E7-specific transcripts in cancers is lower than anticipated from earlier studies using an ORF E6/E7-specific probe that hybridizes with the 5'-ends of the abundant mRNA class.

  3. Evidence for Vertical Transmission of HPV from Mothers to Infants

    Full Text Available Few large studies have evaluated concordance based on a broad spectrum of human papillomavirus (HPV types in oral and genital specimens of mothers and their recently born infants. This information is important in determining whether HPV vaccines administered prior to pregnancy may be useful for preventing vertical transmission. HPV DNA was positive in 30% of mothers and 1.5% of newborns. Maternal/newborn concordance (HPV+/+ or HPV−/− was 71%. Among HPV DNA+ mothers, only 3% of their infants were DNA+ and only 1 pair had the same HPV type. Among HPV− women, 0.8% of infants were HPV+. HPV DNA detected in hospitalized newborns reflects current infection transmitted to infants during pregnancy or delivery. None of the mother/baby HPV DNA+ concordance pairs detected viral types found in HPV vaccines suggesting that vaccination prior to pregnancy is unlikely to be efficacious in preventing vertical transmission.

    HPV is the sexually transmitted agent most common among young people, like college students. The aim of study was to associate sexual behavior characteristics of women with HPV, detected in genital samples taken before the introduction of the HPV vaccine. Female students during 2001-2005 donated genital samples and the samples were re-analyzed in 2013 for HPV genotyping by RT-PCR. The frozen storage of the students' genital samples allowed the detection of HPV DNA and its genotyping after years of sample collection. HPV prevalence was 22%, HPV16 3.9%, and HPV18 1.1%. Age, multiple sexual partners and the partner's age at first sexual intercourse were significantly associated to HPV. Students with ≥ 3 sexual partners and who did not use condom had 12.8 higher odds of being HPV positive. These results made possible the analysis of HPV prevalence changes, before HPV vaccine introduction. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Puerto Rico (PR), is the fifth highest jurisdiction of the United States of America (US) with respect to HIV prevalence and the leading in cervical cancer incidence. This cross-sectional study describes the prevalence and correlates of cervical HPV infection among a clinic-based sample of 302 women living with HIV/AIDS in PR. Data collection included questionnaires, blood and cervical samples. Multivariable logistic regression models were used to estimate the magnitude of association (adjusted Prevalence odds ratio [aPOR]) between HPV cervical infection and other covariates. Mean age of participants was 40.3 years (± 10.3SD). The prevalence of HPV infection was 50.3%; 41.1% for low-risk types and 29.5% for high-risk types. Having ≥ 10 lifetime sexual partners (aPOR = 2.10, 95% CI:1.02-4.29), an abnormal Pap (aPOR = 3.58, 95% CI:1.93-6.62), active genital warts (aPOR = 3.45, 95% CI:1.60-7.42), and CD4 counts ≤ 200 (aPOR = 4.24, 95% CI: 1.67-10.78) were positively associated with any cervical HPV infection. Similar results were observed for HR HPV infection. A high burden of HPV co-infection exists among women living with HIV/AIDS in this population. Given the high incidence of HIV in PR and the higher risk of cervical cancer among women living with HIV/AIDS, HPV vaccination should be promoted in this population. Copyright © 2017 The Authors.

    Cervical cancer is one of the most prevalent gynecological malignancies worldwide. Romania has the highest incidence of this type of cancer in Europe. A successful prevention strategy has to consider the primary prevention measures (including health education on human papilloma virus (HPV) infection but also vaccination). The aim of this study was to assess the knowledge and attitudes of Romanian women about HPV and HPV vaccine. We conducted a cross-sectional study survey of 454 women using an anonymously completed questionnaire covering the awareness and knowledge of HPV infection and attitudes to vaccination. We also analyzed the discussions and conclusion from a focus group of healthcare professionals regarding (1) HPV and HPV awareness and attitude, and (2) suggestions for improving HPV vaccine knowledge and acceptance. 69.2% of women were aware about HPV but their knowledge was minimal and incomplete. While 62.3% had heard about HPV vaccine, only 50.7% had a positive attitude toward it. The main barriers to vaccination were the fear of side effects, the perception that is risky, and the financial concerns. Deficiencies in knowledge were noted for vaccine, genital warts, or risks factors for HPV infection like the early onset of sexual life. The information regarding HPV and vaccine is not always accurate and complete, and only 50.7% of women have a positive attitude toward the vaccine. More educational programs and clearer communication are needed to raise awareness and knowledge regarding HPV and HPV vaccine.

    Full Text Available Specimens from cervical dysplasias or carcinomas and genital condylomata acuminata were retrospectively analysed by in situ hybridization (ISH with bioti-nylated DNA probes for human papillomavirus (HPV types 6, 11, 16 and 18. In the control group no case was positive for HPV DNA. In mild/moderate dysplasias, 4 cases (14% were positive for HPV 6 or 11 and 2 cases (7%, for HPV 16. In the severe dysplasia/in situ carcinoma group, 9 cases (31% showed presence of DNA of HPV types 16 or 18. Six invasive carcinomas (20% were positive for HPV type 16 or 18. Among condylomata acuminata, 22 cases (73% were positive for HPV types 6 or 11. In all ISH-positive cases only one viral type was detected. No correlation between HPV DNA positivity and histological findings of HPV infection was observed. Although less sensitive than some other molecular biology techniques, in situ hybridization with biotinylated DNA probes proved to be simple and useful for detecting and typing HPV in samples routinely received for histopathological analysis.Amostras de displasias ou carcinomas do colo uterino e de condilomas acuminados da região genital foram analisados retrospectivamente por hibridização in situ (HIS com sondas de DNA biotiniladas de papilomavirus humano (HPV tipos 6, 11, 16 e 18.

    Human papillomaviruses are DNA viruses that infect skin or mucosal cells. In the genital tract HPV (especially types 6 and 11) cause genital warts, the commonest viral sexually transmitted disease. At least 13 of the more than 100 known HPV genotypes are oncogenic "high-risk" genotypes. The 2 most common of these (genotypes 16 and 18) cause approximately 70% of all cervical cancers. Oncogenic HPVs particularly HPV 16 are associated with other anogenital cancers, anus, vagina, vulva and penis, and cancers of the head and neck and current estimates are that 5.2% of all cancers are HPV associated. In industrialised countries cervical cancer is controlled by secondary intervention other HPV associated malignancies are increasing in incidence and the burden of HPV associated disease in men is now comparable to that in women in economically developed countries. Randomized control trials with the quadrivalent HPV VLP vaccine demonstrate robust antibody responses and high efficacy against genital warts anal precancers in men. Few countries have recommended male vaccination on the basis that this is not cost effective. However gender-neutral vaccination has been recommended in the USA, Canada, Austria, and Australia. Careful cost effective modeling has preceded these decisions showing that when the burden of disease in men is included in the models then, depending upon coverage, vaccine price, and other factors male vaccination can become cost effective.

    Full Text Available Human papillomaviruses (HPVs are the etiological agents of several genital cancers, including cancer of the uterine cervix. The detection of HPV infection in genital samples may increase the sensitivity of primary and secondary screenings of cervical cancer. HPV testing may also improve the specificity of screening programs, resulting in the avoidance of overtreatment and cost savings for confirmatory procedures. The major determinants of clinical progression of HPV infection include persistence of HPV infection, involvement of high-risk HPV types, high HPV viral load, integration of viral DNA and presence of several potential cofactors. Signal amplification HPV-DNA detection techniques (Hybrid Capture II, Digene Corporation, USA are standardized, commercially available, and capable of detecting several high-risk HPV types. They also increase the sensitivity of screening for high-grade lesions in combination with cytology. The sensitivity of these techniques to detect high-grade lesions is higher than that of cytology, but the referral rate for colposcopy is greater. These techniques are approved for the triage to colposcopy of women with cervical smears interpreted as atypical squamous cells of undetermined significance. Triage and screening for cervical cancer using HPV will probably be restricted to women aged 30 years or older because of the high prevalence of infection in younger women. Amplification techniques are ideal for epidemiological studies because they minimize the misclassification of HPV infection status. These techniques can detect low HPV burden infections. Consensus primers amplify most genital types in one reaction, and the reverse hybridization of amplicons with type-specific probes allows for the typing of HPV-positive samples. Consensus PCR assays are currently under evaluation for diagnostic purposes. HPV testing is currently implemented for the clinical management of women.

    The aim of this review is to present a new light about the HPV infections, their spontaneous evolutions, and their consequences on the transformation of the target tissues. It enlightens the need for vaccination both as a preventive tool and therapeutic agent and the progresses reached so far. HPV infection is often transient and spontaneously reversible. HR HPV persistence is the major cause of cancerous transformation of several tissues. Preventive vaccination has already demonstrated a remarkable efficiency against the development of risk HPV ano-genital infections. Therapeutic vaccination is now also developed to cure the pre existing lesions. Some new screening protocol can be derived from these experiments. Both preventive and therapeutic HPV vaccinations will probably change within the next few years our approach for the screening and therapy of HPV related diseases. Mass vaccination of adolescent female should lower the frequency of these very frequently lethal affections.

    The human papillomavirus (HPV) can cause anogenital cancers and genital warts; however, it can be prevented through the HPV vaccine, which has been available since 2006. While this vaccine is targeted toward 11-to-12-year-olds, 18-to-26-year-old young adult women are eligible for "catch-up" vaccination. Knowledge of HPV may impact HPV vaccine uptake among this population. The purpose of this study was to assess changes in HPV knowledge and HPV vaccine information sources among young adult college women over a 7-year period. Two independent samples (N = 223 for 2008; N = 323 for 2015) completed a 23-item knowledge scale and survey regarding HPV. Adjusted logistic regression models compared the odds of correctly answering each knowledge item between each time period. The study found that HPV knowledge increased significantly over time (p HPV transmission; there is a vaccine for women that prevents certain types of HPV; HPV can cause genital warts; HPV can be passed to a newborn at birth; and even if you do not see a wart, you can transmit HPV. Recent participants were also more likely to correctly report only women can get HPV as false. While improvements in HPV knowledge were found over time, misperceptions regarding outcomes associated with HPV persist. In order to promote HPV vaccination among this population, health literacy skills, in addition to knowledge, should be improved.

    Men who have sex with men (MSM) are at risk of genital warts and anal cancer due to human papillomavirus (HPV) infection. This study explores MSMs' perceptions of HPV and HPV vaccination prior to the introduction of this programme. Focus groups and one-to-one interviews with self-identified MSM were conducted between November 2014 and March 2015 in Brighton, UK. Participants were recruited from community-based lesbian-gay-bisexual-transgender (LGBT) venues and organizations. Discussions were recorded, transcribed verbatim, and analysed using framework analysis. Thirty-three men took part (median age 25 years, IQR: 21-27), most of whom (n = 25) did not know about HPV, anal cancer (31), or HPV vaccination (26). While genital warts and anal cancer were perceived as severe, men did not perceive themselves at risk of HPV. All MSM would accept the HPV vaccine if offered by a health care professional. The challenges of accessing sexual health services or openly discussing same-sex experiences with health care professionals were perceived as barriers to accessing HPV vaccination. Two participants were concerned that selective HPV vaccination could increase stigma and prejudice against MSM, comparable to the AIDS epidemic. Ten MSM were unsure about the effectiveness of HPV vaccination for sexually active men and were in favour of vaccinating all adolescent boys at school. Most MSM have poor knowledge about HPV and associated anal cancer. Despite the lack of concern about HPV, most MSM expressed willingness to receive HPV vaccination. There is a need for health education about the risks of HPV and HPV-related diseases so that MSM can appraise the benefits of being vaccinated. Concerns about HPV vaccine effectiveness in sexually active men and possible stigmatization need to be addressed to optimize HPV vaccine acceptability. Statement of contribution What is already known on this subject? Men who have sex with men (MSM) have poor knowledge about HPV and HPV

    Full Text Available The objectives of the study were to investigate prevalence of cervical human papillomavirus (HPV genotypes to inform HPV vaccination strategy in South Africa and to study factors associated with HPV prevalence. Sexually active, HIV-negative women, aged 16-22 years recruited from Soweto (n = 143 and Cape Town (n = 148 were tested for cervical HPV and other genital infections. Overall HPV prevalence was 66.7% (194/291 in young women. Cape Town women were more likely to have multiple HPV infections than the Soweto women (48.0%, 71/148 versus 35.0%, 50/143 respectively, p = 0.033 and probable HR-HPV types (34.5%, 51/148 versus 21.7%, 31/143 respectively, p = 0.022. The most frequently detected HPV types were HPV-16 (11.7%, HPV-58 (10.3%, HPV-51 (8.9%, HPV-66 (8.6%, HPV-18 and HPV-81 (7.6% each. HPV types targeted by the bivalent HPV vaccine (HPV-16/18 were detected in 18.6% (54/291 of women, while those in the quadrivalent vaccine (HPV-6/11/16/18 were detected in 24.7% (72/291 of women; and those in the nonavalent vaccine (HPV-6/11/16/18/31/33/45/52/58 were detected in 38.5% (112/291 of women. In a multivariable analysis, bacterial vaginosis remained significantly associated with HPV infection (OR: 4.0, 95% CI: 1.4-12.6. Women were more likely to be HPV positive if they had received treatment for STI during the past 6-months (OR: 3.4, 95% CI: 1.1-12.4 or if they had ever been pregnant (OR: 2.3, 95% CI: 1.1-5.5. Compared to women who reported only one sexual partner, those with increased number of lifetime sex partners were more likely to have HPV (4-10 partners: OR: 2.9, 95% CI: 1.1-8.0. The high prevalence of HPV types targeted by the nonavalent HPV vaccine encourages the introduction of this vaccine and catch-up HPV vaccination campaigns in South Africa. The high burden of BV and concurrent STIs also highlights the need to improve the prevention and appropriate management of sexually-acquired and other genital tract infections in South African

    Full Text Available OBJECTIVES: Since the introduction of Australia's human papillomavirus vaccination program, the management rate of genital warts in sexual health clinics and private hospitals has decreased in women of vaccine-eligible age. However, most genital warts in Australia are managed in general practice. This study examines whether a similar decrease occurred in Australian general practice after the introduction of the program. METHODS: Analysis of a nationally representative cross-sectional database of Australian general practice activity (1,175,879 patient encounters with 11,780 general practitioners. Genital warts management rates were estimated for the periods before and after introduction of the program (Pre-program, July 2002-June 2006; Post-program, July 2008-June 2012. Control conditions included genital herpes and gardnerella/bacterial vaginosis in female patients and genital herpes and urethritis in male patients. Trends in management rates by year, pre-vaccine (July 2000-June 2007 and post-vaccine (July 2007-June 2012 were also calculated. RESULTS: Management rate of genital warts among women potentially covered by program (aged 15-27 years decreased by 61% from 4.33 per 1,000 encounters in the Pre-program period to 1.67 in the Post-program period. Trend analysis of the post-vaccine period showed, among women of vaccine eligible age, a significant year-on-year reduction in the rate of genital warts management (p<0.0001 and a significant increase in the management rate of control conditions per year (p<0.0001. For all other age-sex groups there was no significant change in the management rate of genital warts between the Pre- and Post-program periods. CONCLUSION: The large decrease in general practice management of genital warts in women of vaccine-eligible age highlights the success of the program in the wider community.

    Full Text Available Vaccines that protect against infection with the types of human papillomavirus (HPV commonly associated with cervical cancer (HPV 16 and 18 and genital warts (HPV 6 and 11 are expected to become available in the near future. Because HPV vaccines are prophylactic, they must be administered prior to exposure to the virus, ideally during preadolescence or adolescence. The young age of the target vaccination population means that physicians, parents, and patients will all be involved in the decision-making process. Research has shown that parents and patients are more likely to accept a vaccine if it is efficacious, safe, reasonably priced, and recommended by a physician. Widespread education of physicians, patients, and parents about the risks and consequences of HPV infection and the benefits of vaccination will be instrumental for fostering vaccine acceptance.

  13. Epidemiology and Natural History of Human Papillomavirus Infections in the Female Genital Tract

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Human papillomavirus (HPV is the most common newly diagnosed sexually transmitted infection in the United States. Although the majority of sexually active adults will be infected with HPV at least once in their lives, it is sexually active women less than 25 years of age who consistently have the highest rates of infection. Besides youth and gender, common risk factors for HPV infection and clinical sequelae of infection include high number of sexual partners and coinfection with Chlamydia trachomatis or herpes simplex virus. Most HPV infections are cleared by the immune system and do not result in clinical complications. Clinical sequelae in cases of low-risk HPV infection consist of genital warts, and clinical manifestations of high-risk HPV infection include abnormal Pap test results, low-grade squamous intraepithelial lesions (LSIL, high-grade squamous intraepithelial lesions (HSIL, and cervical cancer. LSIL, HSIL, and cervical cancer carry significant morbidity and/or mortality; genital warts and abnormal Pap test results are often significant sources of psychosocial distress. Currently, there are neither effective means of preventing HPV transmission nor cures for clinical manifestations: infection can only be prevented via complete sexual abstinence, while treatment for clinical sequelae such as genital warts and cytologic abnormalities consists of removing the problematic cells and watching for recurrence; this method consumes significant health care resources and is costly. New prophylactic HPV vaccines promise to dramatically reduce the incidence of HPV infection, genital warts, and cytologic abnormalities.

    This analysis assessed the acquisition (incidence) and persistence (clearance) of human papilloma virus (HPV) infection by self-reported race among men in The HPV in Men (HIM) Study, a multinational prospective study of the natural history of genital HPV infections. Self-reported race was categorized as White, Black, Asian/Pacific Islander (PI), or multiple and mixed race. Genital samples were combined for HPV DNA testing and categorized by any, oncogenic, and non-oncogenic HPV infections. Asian/PI race had significantly the lowest incidence of any, oncogenic, and non-oncogenic HPV infection (P < 0.001). In multivariable analyses, Asian/PI race was associated with a lower probability of acquiring any [HR = 0.63; 95% confidence interval (CI), 0.42-0.95] and non-oncogenic HPV infection (HR = 0.61; 95% CI, 0.40-0.93) when compared to Whites. No significant associations were evident for Asian/PI race for clearance. Multiple and mixed race was significantly associated with lower probability of acquiring non-oncogenic HPV infection (HR = 0.83; 95% CI, 0.69-0.99) and borderline significant associations were observed for any HPV (HR = 0.91) and oncogenic infections (HR = 0.92). Multiple and mixed race was associated with a lower probability of clearing any (HR = 0.92; 95% CI, 0.84-1.00) and oncogenic HPV infections (HR = 0.85; 95% CI, 0.75-0.95). Asian/PI race had the lowest incidence of HPV and exhibited a lower probability of acquiring new HPV infections. Multiple and mixed race had the second lowest incidence of infection and was associated with a lower probability of acquiring and clearing an HPV infection. Race-specific differences in HPV infection could be due to behavior, innate genetic differences, or circulating intratypic HPV variants.

    The incidence of human papillomavirus (HPV) associated oropharyngeal squamous cell cancer (OSCC) is on the rise. With the HPV-positive uterine cervix as a reservoir, HPV-positive OSCC is discussed as a sexually transmitted disease. Mechanisms of HPV transmission to the oral cavity are poorly understood. To gain more insight into HPV-transmission routes, cervically HPV-positive women and their sexual partners are screened for oral HPV infection. Women with cervical dysplasia underwent HPV testing of the uterine cervix and tonsillar region via brush test. In addition, sexual partners received oral HPV testing. Tonsillar brush tests of patients admitted for routine surgery served as the control group. The HPV-PCR (Roche Linear Array Kit) was used to differentiate 37 HPV types. All participants completed a risk-factor questionnaire focusing on sexual habits. 101 women were tested HPV-positive at the cervix. Only 3/101 (3 %) were tested HPV-positive in the oropharynx. In 60/101 (60 %) women the sexual partner could be tested for oral HPV infection: testing was positive in 3/60 (5 %). No oral HPV was detected in the control group. The risk-factor questionnaire revealed significant differences between the female study- and control group in terms of age at first sexual intercourse and smoking habits. The limited data suggest that among sexual partners in Germany, HPV transmission to the oropharynx by oral-genital sex or by autoinoculation is a rare and unlikely event with low HPV concordance. Another explanation for the low oral prevalence could be an independent clearance of HPV from the oropharyngeal site compared to cervix uteri or at different time intervals.

    There is now incontrovertible evidence that HPV is the cause of almost all cases of genital warts, cervical dysplasia and cervical cancer. Moreover the current review of the recent literature on HPV in relation to pregnancy found strong indications that HPV plays an important role in adverse...... outcomes of pregnancy. HPV may contribute to infertility and may increase the risk of miscarriage. Recent studies indicate a significant rate of vertical transmission of HPV between mother and child but whether the mode of delivery makes a difference to the risk of transmission remains unknown.

    Full Text Available Abstract Background HPV burden is a predictor for high-grade cervical intraepithelial neoplasia and cancer. The natural history of HPV load in young women being recently exposed to HPV is described in this paper. Methods A total of 636 female university students were followed for 2 years. Cervical specimens with HPV-16, -18, -31, or -45 DNA by consensus PCR were further evaluated with type-specific and β-globin real-time PCR assays. Proportional hazards regression was used to estimate hazard ratios (HR of infection clearance. Generalized estimating equations assessed whether HPV loads was predictive of HPV infection at the subsequent visit. Results HPV loads were consistently higher among women Conclusions The association between HPV load and persistence is not uniform across high-risk genital genotypes. HPV-16 integration was only rarely demonstrated in young women.

    Genital lesions are common in HIV positive patients and aetiology for these are mainly due to HSV, HPV or bacterial. They usually respond to HAART, antiviral or antimicrobials. We are presenting a young patient on HAART with non-healing genital ulcer lesions for sixteen months. He responded well to a change in ART regimen within a period of 15 days. This happened after a change to a more potent ART regimen.

  2. The Potential Impact of Prophylactic HPV Vaccination on Oropharynx Cancer

    Oropharyngeal cancer (OPC) is significantly increasing in incidence in the United States. Given that these epidemiologic trends are driven by HPV, the potential impact of prophylactic HPV vaccines on the prevention of OPC is of interest. To date, the primary evidence supporting the approval of current prophylactic HPV vaccines are large phase III clinical trials focused on prevention of genital disease (cervical and anal cancer, as well as genital warts). These trials reported 89-98% vaccine efficacy for prevention of both premalignant lesions and persistent genital infection. However, these trials were designed before the etiologic relationship between HPV and oropharyngeal cancer was established. There are differences in the epidemiology of oral and genital HPV infection, such as differences in age and gender distributions, which suggest that the vaccine efficacy shown in genital cancers may not be directly translatable to the oropharynx. Evaluation of vaccine efficacy is challenging in the oropharynx because no premalignant lesions analogous to cervical intraepithelial neoplasia (CIN) in cervical cancer has been identified. In order to truly investigate the efficacy of these vaccines in the oropharynx, additional clinical trials with feasible endpoints are needed. PMID:27152637

    The relationship between sexual practices, identity and role among Latino men who have sex with men (MSM) and HIV risk is the subject of ongoing investigation but less is known about how these aspects of sexuality relate to human papilloma-virus (HPV), an independent risk factor for HIV. This observational study investigated the relationship between HPV and sexual practices, identity and role as well as other sexually transmitted infection (STI)/HIV risk factors among HIV-negative heterosexually and homosexually identified Peruvian MSM. Community-based clinic for MSM in Lima, Peru. 756 subjects were screened based on inclusion criteria of: born anatomically male; age ≥18 years; had any anal intercourse with a man during the previous 12 months; residing in metropolitan Lima; HIV negative; willing to commit to twice-yearly clinic visits for 24 months; had not participated in an HIV or HPV vaccine study. 600/756 participants met the inclusion criteria and were enrolled, of whom 48% (284) identified as homosexual and 10% (57) as heterosexual, the basis of the analyses performed. Compared with homosexually identified MSM, heterosexually identified MSM had completed fewer years of formal education and were less likely to have: anogenital HPV or visible anal warts; given oral sex to a man; or used a condom with their most recent female sexual partner (all phomosexually identified MSM by syphilis or high-risk HPV prevalence. HPV burden, wart type (penile vs anal) and select HIV/STI risk behaviours differed between heterosexually and homosexually identified Peruvian MSM. Understanding the implications of these differences can lead to tailored HIV/STI prevention interventions for heterosexually identified MSM.

    Human papillomavirus (HPV) contributes to the most common sexually transmitted infections, with repeated and persistent infection with particular types causing disease in both men and women. Infection with low-risk HPV types can lead to genital warts and benign lesions of the oral cavity, while high-risk types can cause various HPV-related malignancies. The incidence of head and neck cancers has been rising in the past number of decades mostly due to oropharyngeal cancer linked to HPV infection. HPV vaccination has been shown to be effective for cervical and other anogenital HPV-related cancers, and there is significant potential for HPV vaccination to prevent oropharyngeal cancers, given that the HPV types implicated in this disease can be protected against by the HPV vaccine. Few countries have implemented a universal HPV vaccination programme for males and females, with many countries arguing that female-only vaccination programmes protect males via herd immunity and that men who have sex with men will be protected via targeted vaccination programmes. We argue these may be limited in their effectiveness. We propose that the most effective, practical, ethical and potentially cost-effective solution is universal HPV vaccination that might lead to control of HPV-related diseases in men and women alike. © 2016 John Wiley & Sons A/S.

    Human papillomavirus is a major etiologic agent for some human common cancers. Cervical precancer and cancer is the most prevalent dysplasia by HPV genotypes. Various rapid and sensitive methods have been developed into readily HPV genotyping. In the present study, we compared the performance of Real Time PCR, GenoFlow HPV Array, and INNO-LiPA HPV Genotyping Extra Assays with LCD- Array. From 108 cervical samples, HPV was detected in 33 women (30.55%). Among detected HPV genotypes, HPV 6 and 11 were dominant genotypes. Comparing these methods revealed that for Real Time PCR, Genoflow, and INNO-LiPA in comparison with LCD Array, sensitivity and specificity were 94.2%, 93%; 76.7%, 93%; 64%, 96.5%, respectively. Overall, accuracy and precision of these methods were more than 80% and 90%, respectively. It seems that these methods are reliable and suitable for detection and genotyping of HPVs in cervical disorders and other dysplasia associated with human papillomaviruses.

    Data from the National Health and Nutrition Examination Survey ● During 2011-2014, prevalence of any oral human papillomavirus (HPV) for adults aged 18-69 was 7.3%; high-risk HPV was 4.0%. ● Overall, prevalence of any and high-risk oral HPV was lowest among non-Hispanic Asian adults; any oral HPV was highest among non-Hispanic black adults. ● Prevalence of any and high-risk oral HPV was higher in men than women except for high-risk HPV among Asian adults. ● During 2013-2014, prevalence of any and high-risk genital HPV for adults aged 18-59 was 45.2% and 25.1% in men and 39.9% and 20.4% in women, respectively. ● Prevalence of any and high-risk genital HPV was lower among non-Hispanic Asian and higher among non-Hispanic black than both non-Hispanic white and Hispanic men and women. Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States (1). Some HPV types can cause genital warts and are considered low risk, with a small chance for causing cancer. Other types are considered high risk, causing cancer in different areas of the body including the cervix and vagina in women, penis in men, and anus and oropharynx in both men and women (2). This report provides the most recent national estimates of oral HPV prevalence among adults aged 18-69 from the National Health and Nutrition Examination Survey (NHANES) 2011-2014, as well as prevalence of genital HPV among adults aged 18-59 from NHANES 2013-2014.

    Studies have been mixed on whether naturally acquired human papillomavirus (HPV) antibodies may protect against subsequent HPV infection. We performed a systematic review and meta-analysis to assess whether naturally acquired HPV antibodies protect against subsequent genital HPV infection (ie, natural immunity). We searched the MEDLINE and EMBASE databases for studies examining natural HPV immunity against subsequent genital type-specific HPV infection in female and male subjects. We used random-effects models to derive pooled relative risk (RR) estimates for each HPV type. We identified 14 eligible studies that included >24,000 individuals from 18 countries that examined HPV natural immunity. We observed significant protection against subsequent infection in female subjects with HPV-16 (pooled RR, 0.65; 95% confidence interval, .50-.80) and HPV-18 (0.70; .43-.98) but not in male subjects (HPV-16: 1.22; .67-1.77 [P= .05 (test for heterogeneity)]; HPV-18: 1.50; .46-2.55; [P= .15]). We also observed type-specific protection against subsequent infection for a combined measure of HPV-6/11/31/33/35/45/52/58 in female subjects (pooled RR, 0.75; 95% confidence interval, .57-.92).

    This study sought to determine knowledge of and attitude towards human papillomavirus (HPV) infection, HPV-related diseases and HPV vaccines among female undergraduate students at the University of Lagos. A self-administered questionnaire was administered between May and July 2010, to 368 female students aged 16-29years, who were selected from two faculties of the University of Lagos using two-stage sampling method. Data collected included: socio-demographic characteristics, sexual history, awareness and knowledge of HPV infection, cervical cancer and genital warts, and HPV vaccine; the perceived risk of acquiring genital HPV infection and developing cervical cancer or genital warts, and the willingness to receive an HPV vaccine. Only 64 (17.7%) and 52 (14.4%) of the students had ever heard of HPV infection and HPV vaccines respectively. The median HPV knowledge on a 15-item score was 2. Overall, only 11.1% knew that genital HPV infection can cause cervical cancer. Fourteen (6.9%) of those who were aware of cervical cancer agreed they were at risk of developing the disease. Of the 52 students who had heard of the HPV vaccine, 24 (46.2%) knew it was given for cervical cancer prevention and 30 (57.7%) expressed their willingness to receive the vaccine. The knowledge of and the perceived susceptibility to HPV infection and HPV-related diseases among female students in the University of Lagos were generally low. The need for a well-designed HPV-educational program to bridge the knowledge gap cannot be overemphasized. Copyright © 2012 Ministry of Health, Saudi Arabia. Published by Elsevier Ltd.

    Full Text Available Abstract Background Human papillomaviruses (HPV are the aetiological agents of certain benign and malignant tumours of skin and mucosae; the most important of which is cervical cancer. Also, the incidence of ano-genital warts, HPV-anal cancer and oropharyngeal cancers are rising. To help ascertain a useful PCR detection protocol for oropharyngeal cancers, we directly compared three commonly used primer sets in detection of HPV from different clinical samples. Methods We compared PGMY09/11, MY09/11 and GP5+/6+ primers sets in PCRs of 34 clinically diagnosed samples of genital warts, cervical brushings (with associated histological diagnosis and vulval biopsies. All negative samples were subsequently tested using the previously reported PGMY/GP PCR method and amplicons directly sequenced for confirmation and typing. An optimised PCR protocol was then compared to a line blot assay for detection of HPV in 15 oropharyngeal cancer samples. Results PGMY09/11 primers detected HPV presence in more cervical brushing (100% and genital wart (92.9% samples compared to MY09/11 (90% and 64.3% and GP5+/6+ (80% and 64.3% primer sets, respectively. From vulval biopsies, HPV detection rates were: MY09/11 (63.6%, GP5+/6+ (54.5% and PGMY09/11 (54.5%. PGMY/GP nested PCR demonstrated that HPV was present, and direct sequencing confirmed genotypes. This nested PCR protocol showed detection of HPV in 10/15 (66.7% of oropharyngeal cancer samples. Conclusions PGMY09/11 primers are the preferred primer set among these three for primary PCR screening with different clinical samples. MY09/11 and GP5+/6+ may be used (particularly for cervical samples but demonstrate lower detection rates. A nested PCR approach (i.e. a PGMY-GP system may be required to confirm negativity or to detect low levels of HPV, undetectable using current primary PCR methods, as demonstrated using oropharyngeal cancer samples.

    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.

    Data on genotype-specific concordance of oral-oral and genital-oral HPV infections among marital couples are key to understand HPV transmission between spouses. Genotype-specific concordance of HPV infections (oral/genital) and their co-variates among 131 marital couples were determined during 6-year follow-up (FU). Seven oral scrapings were taken from both spouses, accompanied by six genital samplings from the women and one (at baseline) from the male partners. HPV-genotyping was performed by nested PCR and a Luminex®-based Multimetrix Assay. Demographic data were collected with questionnaires at baseline and study conclusion. Prevalence of oral HPV varied from 10.3 to 27.0 % and 15.8 to 31.3 % in women and men, respectively. At baseline, 37.6 % of the male genital samples were HPV-positive while in female genital samples, HPV prevalence varied from 13.3 to 59.4 %. Only 15 couples had HPV genotype-specific concordance (oral-oral n = 7; male oral-female genital n = 9; female oral-male genital n = 2). In the nested case-control setting, higher number of deliveries (OR 0.145, 95%CI 0.030-0.706, p = 0.017) and higher number of intercourse (OR 0.488, 95%CI 0.243-0.978, p = 0.043) decreased the likelihood of concordant HPV infections while practicing oral sex increased the risk (OR 0.299, 95%CI 0.120-0.748, p = 0.010). In multivariate analysis, the likelihood of concordance was decreased by higher number of pregnancies of the female partner (p = 0.020) and by higher frequency of intercourse reported by the male spouse (p = 0.027). To conclude, asymptomatic HPV infections were common in both spouses while genotype-specific concordance was low. This supports the view that HPV profile of the spouses has been established before the current marital relationship.

    Infection with oncogenic human papilloma virus (HPV) types is a necessary cause of cervical cancer. This study assessed the prevalence of HPV infection and genotypes among 1,006 randomly selected women, ages 18 to 24 years, living in Sicily (south Italy). The overall HPV rate was 24.1% (95% confidence interval, 21.5-26.9). The most frequent types were HPV-16 (4.5%), HPV-53 (2.7%), and HPV-84 (2.6%). The prevalence of vaccine types HPV-6, HPV-11, and HPV-18 was 1.4%, 0.1%, and 1.3%, respectively. Cytologic abnormalities were uncommon (3.1%) and associated with HPV detection (P < 0.0001). The only risk factor for HPV infection was the number of sexual partners (women with 2-3 partners versus women with 1 partner: odds ratio, 3.86; 95% confidence interval, 2.45-6.09). Genital HPV infection is relatively high in young Italian women. The high prevalence of viral types other than vaccine types should be taken into account to ensure accurate postvaccine surveillance and early detection of a possible genotype replacement.

  3. The immunology of genital human papilloma virus infection.

    1998-01-01

    This paper reports a presentation by Margaret Stanley, Reader in Epithelial Biology, at the University of Cambridge, in which she reviews the evidence to date regarding the immunology of human papilloma virus (HPV) infection in genital warts. In this she explains that investigations into the immunology of genital wart infections indicate that the replication cycle of papilloma viruses is tightly linked to keratinocyte differentiation - a strategy for immune evasion. While the papilloma virus infects primitive basal cells, viral replication and viral assembly are confined to differentiating superficial epithelial cells. Viral replication and release are confined to cells destined for death and are not associated with inflammation. Such findings suggest that the immune system is ignorant or indifferent to the infection. Evidence from regressing genital warts in humans and animal models suggests that HPV is a cell-mediated immune response of the Th1 type offering a strategy for immunotherapy in benign disease. This is supported by evidence from trials with immunomodulatory agents. While strategies to elicit cytotoxic responses are required for malignant HPV associated lesions, the problems of immune evasion associated with these approaches should not be underestimated. Present optimal therapeutic strategies for genital human papilloma viruses infection would therefore appear to require the induction of a virus specific immune response, either by immunomodulatory agents and/or immunisation with the relevant viral antigens.

    Genital warts (GWs) and laryngeal papillomatosis (LP) are two usually benign pathologies related to infection with human papillomaviruses (HPVs), mainly HPV6 and HPV11. The aim of this work was to describe the genetic diversity of HPV6 and HPV11 isolates found in GWs and LPs, and to analyse the differential involvement of viral variants in either lesion. A total of 231 samples diagnosed as GWs (n = 198) or LP (n = 33) and caused by HPV6 or HPV11 monoinfections were analysed. The phylogenetic relationships of the retrieved viral sequences were explored. We have identified the long control region and the intergenic E2-L2 region as the two most variable regions in both HPV6 and HPV11 genomes. We have generated new HPV6 (n = 166) or HPV11 (n = 65) partial sequences from GWs and LPs lesions spanning both regions and studied them in the context of all available sequences of both types (final n = 412). Our results show a significant (p <0.01) differential presence of HPV6 variants among both pathologies, with HPV6 B variants being preferentially found in GW versus LP samples. No differential involvement of HPV11 variants was observed. Our findings suggest that different HPV6 variants may either show differential tropism or have different potential to induce lesions in different epithelia. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

    HPV vaccines currently marketed in Italy (bivalent and quadrivalent against HPV 16-18 and HPV and 6,11,16,18 respectively) are an extraordinary tool for the primary prevention of HPV related diseases, particularly of the cervical cancer. Although the implementation of the organized vaccination programs has already translated (for some endpoint) in confirmation of clinical efficacy, remains excluded a significant proportion of the diseases linked to non-vaccine HPV types. The new nonavalent vaccine (HPV9), of impending commercialization, represents an evolution of the quadrivalent, the composition of which are added five high-risk HPV types (HPV 31,33,45,52,58). The high clinical-immunological efficacy in experimental trials against the new genotypes (> 96% for CIN2 +), and the equivalence immunogenic to the four already present in the previous vaccine, will render the use of HPV9 a tool able to control in an even more effective HPV disease. The potential of the new vaccine is linked to the reduction of the HPV cancer burden by 2-20% according to anatomical site, with major benefits for cervical cancer, vulvo-vaginal, penile and more limited benefits for anal tumours. Moreover, the potential benefits could be also linked to the reduction of incidence of pre-neoplastic lesions arising in the lower-genital tract, especially in the cervix (CIN2-3), so often cause lengthy and expensive diagnostic and therapeutic procedures. In the face of this broad provision of benefit from HPV9 vaccine, we have also to consider all the variables related to its introduction in the vaccination calendars: the market price, the schedule of administration (currently in three doses) and data regarding the cost-effectiveness. The authors recognize the new vaccine (currently registered only in the US) a lot of potential in the prevention of HPV-related diseases.

    -se que a implementação de vacinas de elevada eficácia na prevenção de tumores benignos e malignos causados por alguns tipos de HPV leve a uma queda acentuada das taxas desses tumores, os quais afetam milhões de pessoas em todo o mundo.OBJECTIVE: To briefly review strategies aimed at the development of rotavirus and HPV vaccines, with emphasis on the current status of studies assessing the safety, reactogenicity, immunogenicity and efficacy of recently developed vaccines. SOURCES OF DATA: This review focuses on articles published from 1996 to 2006, mainly those from the last five years, with special emphasis on data obtained from recently completed studies involving a new live attenuated human rotavirus vaccine and a virus-like particle (HPV vaccine. SUMMARY OF THE FINDINGS: Strategies for developing rotavirus vaccines ranged from Jennerian approaches to the new human-derived rotavirus vaccine. Currently, two rotavirus vaccines are recognized as both efficacious and safe: a pentavalent human-bovine reassortant vaccine and a vaccine derived from an attenuated rotavirus of human origin. The second of these has been evaluated in more than 70,000 infants all over the world. Prophylactic vaccines against HPV have been tested in more than 25,000 young individuals around the world. Results from phase II and III clinical studies indicate that such vaccines against the most common types of HPV, those linked to both genital warts and 70% of cervical cancers, are safe and highly efficacious. CONCLUSIONS: A future rotavirus immunization program covering 60 to 80% of infants worldwide is likely to reduce by at least 50% the number of rotavirus-associated hospitalizations and deaths. It is also reasonable to expect that implementation of HPV prophylactic vaccines will reduce the burden of the HPV-related diseases that presently impact millions of people around the world.

    Human papillomaviruses (HPVs) cause cancer at multiple anatomic sites in men and women, including cervical, oropharyngeal, anal, vulvar, and vaginal cancers in women and oropharyngeal, anal, and penile cancers in men. In this EUROGIN 2014 roadmap, differences in HPV-related cancer and infection burden by gender and anatomic site are reviewed. The proportion of cancers attributable to HPV varies by anatomic site, with nearly 100% of cervical, 88% of anal, and less than 50% of lower genital tract and oropharyngeal cancers attributable to HPV, depending on world region and prevalence of tobacco use. Often mirroring cancer incidence rates, HPV prevalence and infection natural history varies by gender and anatomic site of infection. Oral HPV infection is rare and significantly differs by gender; yet HPV-related cancer incidence at this site is several-fold higher than at either the anal canal or penile epithelium. HPV seroprevalence is significantly higher among women compared to men, likely explaining the differences in age-specific HPV prevalence and incidence patterns observed by gender. Correspondingly, among heterosexual partners, HPV transmission appears higher from women to men. More research is needed to characterize HPV natural history at each anatomic site where HPV causes cancer in men and women, information that is critical to inform the basic science of HPV natural history and the development of future infection and cancer prevention efforts.

    Perinatal route of transmission of human papillomavirus (HPV) has been demonstrated in several small studies. We designed a large prospective cohort study (HERITAGE) to better understand perinatal HPV. The objective of this article is to present the study design and preliminary data. In the first phase of the study, we recruited 167 women in Montreal, Canada, during the first trimester of pregnancy. An additional 850 are currently being recruited in the ongoing phase. Cervicovaginal samples were obtained from mothers in the first trimester and tested for HPV DNA from 36 mucosal genotypes (and repeated in the third trimester for HPV-positive mothers). Placental samples were also taken for HPV DNA testing. Conjunctival, oral, pharyngeal and genital samples were collected for HPV DNA testing in children of HPV-positive mothers at every 3-6 months from birth until 2 years of age. Blood samples were collected in mother and children for HPV serology testing. We found a high prevalence of HPV in pregnant women (45%[95%CI:37-53%]) and in placentas (14%[8-21%]). The proportion of HPV positivity (any site) among children at birth/3-months was 11%[5-22%]. HPV was detected in children in multiple sites including the conjunctiva (5%[10-14%]). The ongoing HERITAGE cohort will help provide a better understanding of perinatal HPV. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

    Background Oral and fingernail human papillomavirus (HPV) detection may be associated with HPV-related carcinoma risk at these non-genital sites and foster transmission to the genitals. We describe the epidemiology of oral and fingernail HPV among mid-adult women. Methods Between 2011–2012, 409 women aged 30–50 years were followed for 6 months. Women completed health and behavior surveys and provided self-collected oral, fingernail, and vaginal specimens at enrollment and exit for type-specific HPV DNA testing. Concordance of type-specific HPV detection across anatomic sites was described with kappa statistics. Using generalized estimating equations or exact logistic regression, we measured the univariate associations of various risk factors with type-specific oral and fingernail HPV detection. Results Prevalence of detecting HPV in the oral cavity (2.4%) and fingernails (3.8%) was low compared to the vagina (33.1%). Concordance across anatomic sites was poor (kappaHPV type (OR=101.0;95%CI: 31.4–748.6) and vaginal HPV viral load (OR per one log10 viral load increase=2.2;95%CI:1.5–5.5) were each associated with fingernail HPV detection. Abnormal Pap history (OR=11.1;95%CI:2.8-infinity), lifetime number of male vaginal sex partners ≥10 (OR vs. 0–3 partners=5.0;95%CI:1.2-infinity), and lifetime number of open-mouth kissing partners ≥16 (OR vs. 0–15 partners=infinity;95%CI:2.6-infinity, by exact logistic regression) were each associated with oral HPV detection. Conclusions While our findings support HPV DNA deposition or autoinoculation between anatomic sites in mid-adult women, the rarity of HPV in the oral cavity and fingernails suggests that oral/fingernail HPV does not account for a significant fraction of HPV in genital sites.

The primary aim of this study is to determine the decisional satisfaction associated with HPV vaccination. STUDY DESIGN: This is a prospective survey conducted at an urban college where women 18-26 years old completed a decisional satisfaction survey about their HPV vaccine experience. RESULTS: Regardless of the decision to accept or reject HPV vaccination, the decisional satisfaction was very high (mean 5-item score = 21.2 (SD 3.8. Women without HPV vaccination were decisionally neutral significantly more often than those already vaccinated; 22% were decisionally neutral for the option to accept HPV vaccination at that visit. Cervical cancer prevention was preferred significantly more often than genital wart prevention in all analyses. CONCLUSIONS: Targeting those who are decisionally neutral about HPV vaccination may result in a higher uptake of HPV vaccination.

    Degenerate oligonucleotide primers were designed for in vitro amplification by polymerase chain reaction (PCR) of a relatively well-conserved portion of the L1 capsid protein gene of genital human papillomaviruses. A specific 441bp fragment was amplified by PCR from genomic clones and clinical biopsy specimens containing DNA from HPV types 6, 11, 16, 18, 31, and 33, as well as from a number of other clinical specimens known to contain unclassified HPV isolates. As some HPV non-specific DNA was also often amplified, another set of degenerate primers was designed which amplified a 335 bp sequence contained within the 441 bp sequence. These nested primers could be used in a two-stage PCR reaction to obtain distinct HPV-specific DNA fragments suitable for direct sequencing. Two-stage PCR was used to demonstrate the presence of HPV DNA in 13 out of 16 biopsies, which had been classified histologically as cervical intraepithelial neoplasia (CIN), but which were negative for HPV on Southern blot hybridization. Seven of these amplification products were sequenced, and one proved to be a previously unsequenced HPV type. The results have important implications for the routine detection and typing of genital and other HPV types in clinical samples.

    The present study explores how genital self-image may be related to considerations of surgically altering one's genitals and documents the wanted genital changes among young adults. Evidence of a nontrivial proportion of respondents (98 of 1,110) had seriously considered elective genital surgery. Regression models indicate that, for both men and women, identifying as heterosexual and reporting lower composite genital self-image scores results in higher odds of considering genital surgery. Additionally for men, feeling unsatisfied with penis size increased the odds. Clinical and educational efforts to normalize and celebrate genital variation may influence considerations for genital modification in young adults.

    To understand likelihood of type replacement after vaccination against the high-risk human papillomavirus (HPV) types, we evaluated competition of the seven most common genital HPV types in a population sample of unvaccinated, fertile-aged Finnish women. First trimester sera from two consecutive pregnancies were retrieved from 3,183 Finnish women (mean age, 23.1 years) of whom 42.3% had antibodies to at least one HPV type (6/11/16/18/31/33/45) at the baseline. Antibody positivity to more than one HPV types by the second pregnancy was common among the baseline HPV seropositives. However, compared to baseline HPV-seronegative women, significantly increased incidence rate ratios (IRRs), indicating an increased risk to seroconvert for another HPV type, were consistently noted only for HPV33 among baseline HPV16 or HPV18 antibody (ab)-positive women: HPV(16ab only) (→) (16&33ab) IRR 2.9 [95% confidence interval (CI) 1.6-5.4] and HPV(18ab only) (→) (18&33ab) IRR 2.5 (95% CI 1.1-6.0), irrespectively of the presence of antibodies to other HPV types at baseline: HPV(16ab) (→) (16&33ab) IRR 3.2 (95% CI 2.0-5.2) and HPV(18ab) (→) (18&33ab) IRR 3.6 (95% CI 2.1-5.9). Our findings suggest a possible competitive advantage for HPV33 over other genital HPV types in the unvaccinated population. HPV33 should be monitored for type replacement after HPV mass vaccination.

(3 Results: 54.9% knew that HPV caused cervical cancer, and 52.1% identified HPV as an STD. Knowledge of risk factors such as promiscuity (46.9% and early sexual activity (15.6% was low, but higher than that of further HPV-induced diseases: genital warts (in females 9.9%, in males 9%, anal cancer (in females 2.2%, in males 1.9%, penile cancer (9.4%, and vulvar cancer (7.8%. A percentage of 14.6% feared getting infected, and 35.7% supported compulsory HPV vaccination. A percentage of 51.2% would have their future children vaccinated—significantly more girls than boys. (4 Conclusion: Our results support the findings of previous studies about young adults’ HPV-related knowledge, which was poor, especially regarding pathologies in men. Despite the low level of awareness, the students’ attitude was mostly positive when asked about vaccinating their future children.

    Full Text Available Abstract Background Genital warts, which are caused by infection with human papillomavirus (HPV, are one of the most common sexually transmitted diseases in Europe. Although genital warts are commonly perceived as a non-serious condition, treatment is often long, of varying effectiveness and the recurrence rate is high. Very few studies have been performed on the personal consequences of genital warts. The aim of this qualitative study, set in Denmark, was to examine the ways in which genital warts may affect patients' quality of life. Methods To obtain an in-depth understanding of patients' perceptions of genital warts, we used qualitative focus-group interviews with five men and five women aged between 18 and 30 years who had genital warts. The interview guide was based on a literature review that identified important issues and questions. The data were analysed using a medical anthropological approach. Results Patients' experiences were related to cultural conceptions of venereal diseases and the respective identities and sexuality of the sexes. The disease had negative psychological and social effects both for men and for women and it affected their sex and love lives, in particular. The psychological burden of the disease was increased by the uncertain timeline and the varying effectiveness of treatment. We identified a need for more patient information about the disease and its psycho-sexual aspects. Conclusions The men and women participating in this study considered their quality of life to be significantly lowered because of genital warts. The experiences described by the participants give insights that may be valuable in treatment and counselling. The quadrivalent HPV vaccine that has now been added to the childhood vaccination programme for girls in Denmark for the prevention of cervical cancer can also prevent 90% of cases of genital warts. Our results suggest that HPV vaccination could considerably reduce the largely unacknowledged

    Human papillomavirus (HPV)-related screening technologies and HPV vaccination offer enormous potential for cancer prevention, notably prevention of cervical cancer. The effectiveness of these approaches is, however, suboptimal owing to limited implementation of screening programmes and restricted...... indications for HPV vaccination. Trials of HPV vaccination in women aged up to 55 years have shown almost 90% protection from cervical precancer caused by HPV16/18 among HPV16/18-DNA-negative women. We propose extending routine vaccination programmes to women of up to 30 years of age (and to the 45-50-year...... age groups in some settings), paired with at least one HPV-screening test at age 30 years or older. Expanding the indications for HPV vaccination and much greater use of HPV testing in screening programmes has the potential to accelerate the decline in cervical cancer incidence. Such a combined...

    Background Clinical studies demonstrate increased prevalence of human papillomavirus (HPV)-associated disease in HIV-infected individuals and an increased risk of HIV acquisition in HPV-infected individuals. The mechanisms underlying this synergy are not defined. We hypothesize that women with cervical intraepithelial neoplasia (CIN) will exhibit changes in soluble mucosal immunity that may promote HPV persistence and facilitate HIV infection. Methods The concentrations of immune mediators and endogenous anti-Escherichia coli activity in genital tract secretions collected by cervicovaginal lavage were compared in HIV-negative women with high-risk HPV-positive (HRHPV+) CIN-3 (n = 37), HRHPV+ CIN-1 (n = 12), or PAP-negative control subjects (n = 57). Results Compared with control subjects, women with CIN-3 or CIN-1 displayed significantly higher levels of proinflammatory cytokines including interleukin (IL)-1α, IL-1β, and IL-8 (P < 0.002) and significantly lower levels of anti-inflammatory mediators and antimicrobial peptides, including IL-1 receptor antagonist, secretory leukocyte protease inhibitor (P < 0.01), and human β defensins 2 and 3 (P < 0.02). There was no significant difference in endogenous anti-E. coli activity after controlling for age and sample storage time. Conclusion HRHPV+ CIN is characterized by changes in soluble mucosal immunity that could contribute to HPV persistence. The observed mucosal inflammation suggests a mechanism that may also contribute to the epidemiologic link between persistent HPV and HIV. PMID:22801340

    To determine the prevalence of HPV and the risky sexual behaviors associated to it in a sample of male college students, taking into account genotype and viral load. From 2002 to 2003, male students from the Autonomous University of Morelos State completed a questionnaire and provided self-collected genital samples to detect and quantify HPV. We performed a bivariate and a multivariate logistic regression analysis to identify correlates associated with the infection and to assess the viral load as a function of the viral infecting type. The fragments of β-globin gene and L1 of HPV, were amplified, purified and cloned, to evaluate viral load. Among 253 subjects, HPV prevalence was 19.4%, and HPV16 was the most common subtype. History of STIs (OR=4.8; 95% CI 1.2-18.9), contraceptive pill use by female partner (OR=2.6; 95% CI 1.1-6.3) and exchanging sex for money (OR=4.9; 95% CI 1.2-20) were associated to the HPV infection. HPV16 viral load was 7.8 copies (HPV/beta-globin) compared to 0.9 copies for other HPV types. HPV16 displayed the highest viral load, and it was the most prevalent. It was found that using contraceptive pills by female partners was associated with HPV infection. Copyright © 2013 Elsevier Editora Ltda. All rights reserved.

    Problem High-risk human papillomavirus (HR-HPV) is prevalent in HIV-infected women and may be associated with mucosal changes that promote HIV replication. Method of Study Innate immune molecules, antimicrobial activity, HIV RNA, and HPV DNA genotypes were measured in a cross-sectional study of 128 HIV-infected women categorized into HPV-16 (n=8), other HR-HPV (n=41), and non-HR-HPV controls (n=79). Results Compared to controls, HR-HPV groups had higher plasma viral loads (p=0.004), lower CD4 cells (p=0.02), more genital tract HIV RNA (p=0.03), greater number of different HPV types (p<0.001), higher cervicovaginal lavage (CVL) IL-1α (p=0.03) and human beta defensin 2 (HBD2) (p=0.049), and less anti-HIVBal activity (p=0.03). HPV-16 remained significantly associated with higher HBD2 (p=0.03), higher IL-1α (p=0.009), and lower anti-HIVBaL activity (p=0.03) compared to controls after adjusting for plasma viral load and CD4 T cell count. Conclusion HR-HPV is associated with mucosal changes in HIV-infected women that could adversely impact genital tract health. PMID:26685115

    Human papillomavirus (HPV) infections are common and generally harmless, but persistent infections can bring health problems like cancer and genital warts. For the uninfected group, HPV vaccines provide safe and effective protection, but they're type-restricted and expensive. For those infected, so far there have been a handful of treatments for HPV-associated benign or malignant diseases, traditional Chinese medicine being one of them. This systematic review focuses on the application of traditional Chinese medicine in HPV infection and related diseases on the basis of clinical findings. Moreover it covers compositions and mechanisms based on in vitro laboratory methods and animal models. Traditional Chinese medicine improves clinical index in the treatment of cervical cancer and genital warts; the mechanisms behind the effectiveness might be the regulation of cell apoptosis, viral gene transcription and translation, cell signal transduction pathways, and immune function.

    2003-01-01

    ONE OF THE RISK FACTORS FOR HUMAN PAPILLOMAVIRUS (HPV) INFECTION and subsequent lower genital tract neoplasias and cancers is impaired cell-mediated immunity. HIV-positive women with severe immunosuppression are 5 times more likely than HIV-negative women to have lower genital tract neoplasias. A corresponding increase in the risk of invasive vulvar and anal cancers, but not of cervical cancer, has also been observed among HIV-positive women. Treatment failure and recurrence of neoplasia occur much more frequently among HIV-positive than among HIV-negative women. In this review, we discuss recent advances in the understanding of the relation between HIV and HPV coinfection and the development of lower genital tract neoplasias and cancers in women. In addition, we present strategies for monitoring and treating noninvasive and invasive neoplasias of the lower genital tract in HIV-positive women. PMID:12952805

    OBJECTIVES: To determine the average cost of a case of genital warts, for both males and females, with a view to informing the current debate as to which Human papillomavirus vaccine would have maximum cost-effectiveness in the Irish population. METHODS: Contact time between patients and healthcare professionals was prospectively measured at five genitourinary medicine clinics in the south-west of Ireland, over a period of 3 weeks. By identifying all those with genital warts, it was possible to calculate the proportion of total time taken by patients with this condition, and from this to calculate a cost per incident case, by gender. RESULTS: A total of 25.5% of attendances were for genital warts, and these patients used 26.2% of total clinic time (CI 25.4 to 27.0%). The average cost calculated for genital warts was 335 euros per incident case, and by gender 300 euros per male case and 366 euros per female case. CONCLUSIONS: There are considerable costs associated with the treatment of genital warts, with female cases representing a higher cost than males. By vaccinating with the quadrivalent HPV vaccine, there are significant savings to be made.

    The current research focuses on sexual risk behaviour among young adult Canadians who have not been vaccinated against HPV. Six hundred and forty-six Canadian university undergraduates completed a self-administered survey assessing HPV vaccination status and sexual risk behaviour. Five hundred and thirty-seven participants (154 men and 383 women aged 17-23) who met eligibility criteria were analyzed. 48.5% (n = 185) of female and 89.6% (n = 138) of male participants had not been vaccinated against HPV. In the unvaccinated cohort, 51.4% (n = 95) of women were coitally experienced, 49.2% (n = 91) reported experience with oral sex, and 6.5% (n = 12) reported experience with receptive anal intercourse. 55.1% (n = 76) of men were coitally experienced, 22.5% (n = 31) of men reported receptive oral sex, and 2.9% (n = 4) of men reported receptive anal intercourse. Using validated sexual risk behaviour cut-offs, we determined that in the female unvaccinated population, the proportion at significantly increased risk for genital warts, cervical, anal, and oropharyngeal cancer was 11.0%, 30.0%, 6.5%, and 49.2% respectively. In the male unvaccinated population, the proportion at significantly elevated risk for genital warts and anal cancer was 27.2% and 2.9% respectively. Unvaccinated young Canadian women and men commonly engaged in sexual risk behaviours for HPV infection, engaged in sexual risk behaviours at a similar level as their vaccinated counterparts, and a substantial number were at elevated risk of HPV related morbidities at a young age. Findings contribute to an evidence-based case for redoubling efforts to encourage HPV vaccination among unvaccinated young Canadians who are at risk of HPV infection.

    Full Text Available Human papillomavirus 16 (HPV16 species group (alpha-9 of the Alphapapillomavirus genus contains HPV16, HPV31, HPV33, HPV35, HPV52, HPV58 and HPV67. These HPVs account for 75% of invasive cervical cancers worldwide. Viral variants of these HPVs differ in evolutionary history and pathogenicity. Moreover, a comprehensive nomenclature system for HPV variants is lacking, limiting comparisons between studies.DNA from cervical samples previously characterized for HPV type were obtained from multiple geographic regions to screen for novel variants. The complete 8 kb genomes of 120 variants representing the major and minor lineages of the HPV16-related alpha-9 HPV types were sequenced to capture maximum viral heterogeneity. Viral evolution was characterized by constructing phylogenic trees based on complete genomes using multiple algorithms. Maximal and viral region specific divergence was calculated by global and pairwise alignments. Variant lineages were classified and named using an alphanumeric system; the prototype genome was assigned to the A lineage for all types.The range of genome-genome sequence heterogeneity varied from 0.6% for HPV35 to 2.2% for HPV52 and included 1.4% for HPV31, 1.1% for HPV33, 1.7% for HPV58 and 1.1% for HPV67. Nucleotide differences of approximately 1.0% - 10.0% and 0.5%-1.0% of the complete genomes were used to define variant lineages and sublineages, respectively. Each gene/region differs in sequence diversity, from most variable to least variable: noncoding region 1 (NCR1 /noncoding region 2 (NCR2 >upstream regulatory region (URR> E6/E7 > E2/L2 > E1/L1.These data define maximum viral genomic heterogeneity of HPV16-related alpha-9 HPV variants. The proposed nomenclature system facilitates the comparison of variants across epidemiological studies. Sequence diversity and phylogenies of this clinically important group of HPVs provides the basis for further studies of discrete viral evolution, epidemiology, pathogenesis and

    The discovery that the Human PapillomaVirus (HPV) is the necessary cause of cervical cancer has led to the development of prophylactic vaccines. Cervical cancer is the second most common cause of death from cancer among young women in Europe: mortality is still high, despite its important reduction due to screening programs for early detection. Besides cervical cancer, HPV is responsible for a significant proportion of other anogenital cancers and an increasing number of oropharyngeal cancers, representing together an at least equal burden compared to cervical cancer. HPV is also responsible for conditions such as condyloma acuminata (genital warts) and recurrent respiratory papillomatosis. Organized vaccination programs against HPV have the potential to prevent about 70% of cervical cancers and the vast majority of the other HPV-related conditions. Recommendations for HPV vaccination of at least one cohort of females have been issued in nearly all western European countries, and national/regional publicly funded vaccination programs have been introduced in most of them. Different approaches have been chosen for the implementation of HPV vaccination, based on the organization of each country's health care system. A brief outline of these programs in Europe is presented. As for all preventive public health interventions, high coverage of the target population with HPV vaccines pre-exposure is essential to achieve maximum reduction of cases: therefore, in order to obtain the maximum and most equitable coverage and future benefit, programs targeting adolescents before exposure to HPV should be preferred and population-based. Catch-up programs should also be implemented wherever possible, in order to deliver more and even earlier benefits, and effective communication strategies need to be adopted.

MÉTODOS: estudo de validação de teste diagnóstico realizado em 893 mulheres de 18 a 65 anos, rastreadas simultaneamente com colpocitologia, IVA e colposcopia, em unidade de saúde pública de Recife, PE. A IVA foi realizada por embrocação do colo com ácido acético a 5% e observação a olho nu, com auxílio de foco clínico comum. Considerou-se como positividade o achado de qualquer lesão aceto-branca no colo. O padrão-ouro foi o histopatológico de biópsia cervical, realizado sempre que qualquer um dos três testes resultasse anormal. Foram estimados e comparados os indicadores de validade de cada teste, com os respectivos intervalos de confiança a 95%. A concordância entre os resultados dos testes foi avaliada pelo coeficiente kappa (k. RESULTADOS: das 303 mulheres biopsiadas, o estudo histopatológico foi anormal em 24. Deste total, a IVA foi positiva em 22, conferindo-lhe sensibilidade estimada de 91,7%, especificidade de 68,9%, valor preditivo positivo de 7,5% e valor preditivo negativo de 99,7%. Comparando-se os intervalos de confiança a 95%, a IVA mostrou maior sensibilidade que a colpocitologia, mas com menores especificidade e valor preditivo positivo. Houve fraca concordância entre os resultados da IVA e da colpocitologia (k=0,02 e excelente concordância com os da colposcopia (k=0,93. CONCLUSÃO: a IVA foi muito mais sensível que a colpocitologia no rastreamento das NIC e lesões HPV-induzidas e teve o mesmo desempenho da colposcopia. Sua baixa especificidade foi responsável por um elevado número de resultados falso-positivos.PURPOSE: to estimate the validity of visual inspection of cervical intraepithelial neoplasia (CIN and HPV-induced lesion screening, after acetic

Aims: To determine the presence of HPV in genital skin squamous cell carcinomas and to see the relationship between HPV infection and changes in the expression of Ki-67 antigen (Ki-67, p53 protein (p53, retinoblastoma protein (pRb and E-cadherin and to alterations in Langerhans cell density, if any. Methods: A descriptive, comparative, retrospective and cross-sectional study was performed with all the cases diagnosed as squamous cell carcinomas of the genital skin at the Dermatopathology Service from 2001 to 2011. The diagnosis was verified by histopathological examination. The presence of HPV was examined using chromogenic in situ hybridization, and protein expression was studied via immunohistochemical analysis. Results: The 34 cases studied were verified as squamous cell carcinomas and 44.1% were HPV positive. The degree of expression of pRb was 17.50% ±14.11% (mean ± SD in HPV-positive cases and 29.74% ±20.38% in HPV-negative cases (P = 0.0236. The degree of expression of Ki-67 was 47.67% ±30.64% in HPV-positive cases and 29.87% ±15.95% in HPV-negative cases (P = 0.0273. Conclusion: HPV infection was related to lower pRb expression and higher Ki-67 expression in comparison with HPV negative samples. We could not find a relationship between HPV infection and the degree of expression of p53 and E-cadherin or with Langerhans cell density.

    The burden of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) is disproportionately high among men, yet empirical evidence regarding the difference in prevalence of oral HPV infection between men and women is limited. Concordance of oral and genital HPV infection among men is unknown. To determine the prevalence of oral HPV infection, as well as the concordance of oral and genital HPV infection, among U.S. men and women. Nationally representative survey. Civilian noninstitutionalized population. Adults aged 18 to 69 years from NHANES (National Health and Nutrition Examination Survey), 2011 to 2014. Oral rinse, penile swab, and vaginal swab specimens were evaluated by polymerase chain reaction followed by type-specific hybridization. The overall prevalence of oral HPV infection was 11.5% (95% CI, 9.8% to 13.1%) in men and 3.2% (CI, 2.7% to 3.8%) in women (equating to 11 million men and 3.2 million women nationwide). High-risk oral HPV infection was more prevalent among men (7.3% [CI, 6.0% to 8.6%]) than women (1.4% [CI, 1.0% to 1.8%]). Oral HPV 16 was 6 times more common in men (1.8% [CI, 1.3% to 2.2%]) than women (0.3% [CI, 0.1% to 0.5%]) (1.7 million men vs. 0.27 million women). Among men and women who reported having same-sex partners, the prevalence of high-risk HPV infection was 12.7% (CI, 7.0% to 18.4%) and 3.6% (CI, 1.4% to 5.9%), respectively. Among men who reported having 2 or more same-sex oral sex partners, the prevalence of high-risk HPV infection was 22.2% (CI, 9.6% to 34.8%). Oral HPV prevalence among men with concurrent genital HPV infection was 4-fold greater (19.3%) than among those without it (4.4%). Men had 5.4% (CI, 5.1% to 5.8%) greater predicted probability of high-risk oral HPV infection than women. The predicted probability of high-risk oral HPV infection was greatest among black participants, those who smoked more than 20 cigarettes daily, current marijuana users, and those who reported 16 or more lifetime

    Two clinically relevant high-risk HPV (HR-HPV) types 16 and 18 are etiologically associated with the development of cervical carcinoma and are also reported to be present in many other carcinomas in extra-genital organ sites. Presence of HPV has been reported in breast carcinoma which is the second most common cancer in India and is showing a fast rising trend in urban population. The two early genes E6 and E7 of HPV type 16 have been shown to immortalize breast epithelial cells in vitro, but the role of HPV infection in breast carcinogenesis is highly controversial. Present study has therefore been undertaken to analyze the prevalence of HPV infection in both breast cancer tissues and blood samples from a large number of Indian women with breast cancer from different geographic regions. The presence of all mucosal HPVs and the most common high-risk HPV types 16 and 18 DNA was detected by two different PCR methods - (i) conventional PCR assays using consensus primers (MY09/11, or GP5+/GP6+) or HPV16 E6/E7 primers and (ii) highly sensitive Real-Time PCR. A total of 228 biopsies and corresponding 142 blood samples collected prospectively from 252 patients from four different regions of India with significant socio-cultural, ethnic and demographic variations were tested. All biopsies and blood samples of breast cancer patients tested by PCR methods did not show positivity for HPV DNA sequences in conventional PCRs either by MY09/11 or by GP5+/GP6+/HPV16 E6/E7 primers. Further testing of these samples by real time PCR also failed to detect HPV DNA sequences. Lack of detection of HPV DNA either in the tumor or in the blood DNA of breast cancer patients by both conventional and real time PCR does not support a role of genital HPV in the pathogenesis of breast cancer in Indian women

    Full Text Available The morbidity and mortality due to tuberculosis (TB is high worldwide, and the burden of disease among women is significant, especially in developing countries. Mycobacterium tuberculosis bacilli reach the genital tract primarily by haematogenous spread and dissemination from foci outside the genitalia with lungs as the common primary focus. Genital TB in females is a chronic disease with low-grade symptoms. The fallopian tubes are affected in almost all cases of genital TB, and along with endometrial involvement, it causes infertility in patients. Many women present with atypical symptoms which mimic other gynaecological conditions. A combination of investigations is needed to establish the diagnosis of female genital TB (FGTB. Multidrug anti-TB treatment is the mainstay of management and surgery may be required in advanced cases. Conception rates are low among infertile women with genital TB even after multidrug therapy for TB, and the risk of complications such as ectopic pregnancy and miscarriage is high. More research is needed on the changing trends in the prevalence and on the appropriate methods for diagnosis of FGTB.

    Full Text Available Body piercing has been practiced for thousands of years all over the world for beautification, religion, initiation rites or status reasons. Genital piercings also have a significant background and have been practiced for enhancing sexual pleasure, chastity, shocking or as a protest against a conservative society. As the popularity of genital piercings increased in the last years, the number of complications is also on the rise. It is therefore important for the medical professionals to have at least basic knowledge regarding this practice, as it might be required in the management of unpredictable complications.

    To provide Canadian gynaecologists with evidence-based direction for female genital cosmetic surgery in response to increasing requests for, and availability of, vaginal and vulvar surgeries that fall well outside the traditional realm of medically-indicated reconstructions. Published literature was retrieved through searches of PubMed or MEDLINE, CINAHL, and The Cochrane Library in 2011 and 2012 using appropriate controlled vocabulary and key words (female genital cosmetic surgery). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to May 2012. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table). Recommendations 1. The obstetrician and gynaecologist should play an important role in helping women to understand their anatomy and to respect individual variations. (III-A) 2. For women who present with requests for vaginal cosmetic procedures, a complete medical, sexual, and gynaecologic history should be obtained and the absence of any major sexual or psychological dysfunction should be ascertained. Any possibility of coercion or exploitation should be ruled out. (III-B) 3. Counselling should be a priority for women requesting female genital cosmetic surgery. Topics should include normal variation and physiological changes over the lifespan, as well as the possibility of unintended consequences of cosmetic surgery to the genital area. The lack of evidence regarding outcomes and the lack of data on the

    A persistent human papillomavirus (HPV) infection is a prerequisite for a HPV related cancer to develop. Asymptomatic, persistent HPV infections are not only found in genital tract, but also on oral mucosa. Oral HPV persistence may be associated with behavioural factors, but data on the role of innate immunity in oral HPV infections are still limited. Salivary concentrations of matrix metalloproteinases MMP-8 and MMP-9, tissue inhibitor of MMPs (TIMP-1), myeloperoxidase, and serum concentrations of MMP-8 were analysed in women with a persistent oral HPV infection and, as a control, in women who remained HPV DNA-negative during a 6-year follow-up. The effects of smoking, lactation and alcohol use on the salivary and serum parameters were assessed, too. A nested case-control setting was used to select a subgroup of 57 women with a persistent oral HPV infection and 102 controls from the Finnish Family HPV Study. The salivary MMP-8/TIMP-1 molar ratio was lower in HPV DNA-positive women than in controls (p=0.036). The difference was more pronounced in non-smoking women, in this group also the salivary MMP-8 levels differed (p=0.047). There was a correlation between the salivary concentrations of myeloperoxidase and MMP-8 (r=0.567, poral HPV infection was associated with a low salivary MMP-8 concentration indicating eventually a failure in oral anti-inflammatory defence.

    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. 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. 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. Cutaneous beta-HPV does not appear to be contributing to pathogenesis in male genital skin. Copyright © 2016. Published by Elsevier Inc.

    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. To examine the association between seropositivity to cutaneous HPV types and the risk of subsequent development of EGLs. 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. 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. Overall, seropositivity to cutaneous HPV was common among men; however, it appears that cutaneous HPV is not associated with the development of

    The association between human papillomavirus (HPV) infection and non-melanoma skin cancers (NMSCs) such as squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) is not yet fully understood. We analysed the prevalence and spectrum of cutaneous beta-HPV types and mucosal/genital HPV types in paired biopsies (tumour and corresponding perilesional skin) obtained from 50 BCC immunocompetent patients. A small group of SCC patients (n=9) was also included. We also evaluated some previously postulated risk factors for HPV infection in NMSC patients. All biopsies were negative for mucosal/genital HPV types. Overall, beta-HPV DNA was detected more often in SCC compared to BCC patients (78% vs 55% of total samples). The frequency of infection increased with the patient's age [OR=4.88 (95% CI 1.29-18.39)]. There was no significant correlation between beta-HPV positivity and sex, skin type and UV exposure. The prevalence of beta-HPV species 1 types was significantly higher than those belonging to other beta-HPV species in biopsies from BCC (p=0.022) but not from SCC subjects (p=0.091). There was no significant difference in the overall prevalence of beta-HPV infection and the number of viral types between tumour lesions and perilesional skin. BCC samples were significantly more likely to be infected with beta-HPV species 1 types compared to perilesional skin (p=0.036) and showed a higher frequency of mixed infections (p=0.028). These findings demonstrate that beta-HPV types belonging to species 1 are the most common HPV types detected in the skin of BCC patients. Moreover beta-1-HPV types and mixed infections are significantly more frequent in tumour samples than in healthy perilesional skin. Our results suggest that beta-1-HPVs as well as co-infection with more than one viral type could be important in NMSC and in particular in BCC.Further studies aimed to compare the biological activity of viral types in tumours and in healthy skin (viral replication and expression

    The estimated 165,000 cancers of the male genital system that will occur in the United States during 1993 represent one fourth of the expected 600,000 newly diagnosed cancers in American males for the year. Data were collected by the Surveillance, Epidemiology, and End Results (SEER) program. This paper examines histologic data collected by the SEER program from 1973-1987 and focuses on incidence, stage at diagnosis, and survival for the dominant histologic types of cancer that occur in the four major topographic divisions of the male genital system: prostate gland, testis, penis, and scrotum. Some less common histologic types within each organ are also discussed. The incidence of male genital cancer has increased rapidly over the period of study. Cancers of the prostate, most of which are adenocarcinomas, represent more than 92% of all male genital cancers. Among adolescents and young men, germ cell cancers of the testis predominate, but decline rapidly in occurrence after 40 years of age. Blacks had higher incidence rates for prostate cancer than whites; however, the situation was reversed for testicular cancer. Survival increased dramatically for testicular cancer. Cancers of the penis and scrotum of any histologic type are uncommon in the United States. The increased incidence of prostate adenocarcinomas and testis germ cell tumors indicates the need for further etiologic studies as a basis for prevention efforts.

    Genital plastic surgery for women has come under scrutiny and has been the topic of discussion in the news media, online, and in medical editorials. In the absence of measurable standards of care, lack of evidence-based outcome norms, and little standardization either in nomenclature or training requirements, concern has been raised by both ethicists and specialty organizations.Some women request alteration of their vulvas and vaginas for reasons of cosmesis, increasing self-esteem, and improving sexual function. Patients must be assured their surgeon is properly trained and should understand that few validated long-term safety or outcome data are presently available in this relatively new field. Women also should be made aware that, although they may wish to cosmetically or physically alter their external genitalia, this does not mean that they are developmentally or structurally "abnormal." It is important that training guidelines for practitioners be established and that long-term outcome, psychosexual, and safety data be published. The genital plastic surgeon must have sufficient training in sexual medicine to withhold these procedures from women with sexual dysfunction, mental impairment, or body dysmorphic disorder. In an atmosphere in which trademarked marketing terms are becoming part of the lexicon, a more descriptive terminology is suggested, incorporating the terms "labiaplasty," "reduction of clitoral hood," "perineoplasty," "hymenoplasty," and "vaginoplasty." The term "female cosmetic genital surgery" is presented as a descriptive umbrella encompassing these genital plastic procedures.

    Full Text Available High-risk human papillomaviruses (HR-HPV are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investigate the epidemiology of human papillomavirus infections of the oral mucosa without pathology. A cross-sectional study was performed; samples from 390 women seeking prenatal care, Pap smears, family planning or gynecological diseases were studied. Oral cells were collected by direct swab sampling. Information regarding sociodemographic status, sexual behavior, infectious diseases, contraceptive history and tobacco and alcohol consumption were obtained through direct interviews. HPV and genotypes were detected by type-specific polymerase chain reaction. Our results revealed that 14% of the women studied had an oral HPV infection. Women ≤ 20 years of age had the highest HPV prevalence (24.5%. In total, seven genotypes were identified, including the high-risk genotypes 16, 18, 58 and 59 and the low-risk genotypes 6, 81 and 13, the latter of which is a type exclusive to oral mucosa. Sexual behavior was not associated with the presence of genital HPV types in the oral mucosa. Genital HPV types were present in the oral mucosa of women without associated clinical manifestations; however, sexual behavior was not associated with infection, and therefore others routes of transmission should be explored.

    Low risk HPV types 6/11 are responsible for some low-grade cytological abnormalities. Most economic analyses of HPV vaccination have estimated the additional benefit of HPV 6/11 protection by the quadrivalent vaccine, over the bivalent, based on reduction of genital warts but have not included reduction in repeat smears and colposcopies due to low-grade abnormalities. We investigate the contribution of HPV types 6/11 to abnormal smears and associated costs in England. The risk of borderline or mild dysplasia due to HPV 6/11 infection was estimated from a study of type-specific HPV DNA in cervical screening specimens collected throughout England. A Markov model representing 10 million women with HPV 6/11 or with no HPV infection from 24 to 64 years was developed to estimate the number of abnormal smears, subsequent repeat smears and colposcopies due to HPV 6/11 associated with borderline or mild dysplasia. Fitting was achieved by varying the force of infection, probability of borderline or mild dysplasia if HPV-uninfected or infected with HPV 6/11 and the duration of infection. The relative risks of borderline or mild dysplasia when infected with HPV 6/11 compared to not being HPV infected were 6.32 (95% credible interval 1.56-25.6) and 17.5 (1.02-300) respectively. Using best fitting parameters we find the costs incurred are between £170 and £195 per abnormal smear due to infection with HPV 6/11. In England, the impact of cytological abnormalities due to HPV 6/11 is relatively small, but not negligible. A vaccine that protects against HPV 6/11 infections could reduce costs associated with borderline and mild dysplasia, and associated colposcopies. These benefits should be considered when formulating immunisation policy, if possible. Smears and colposcopies in those uninfected with HPV far outnumber those in women infected with HPV 6/11.

    HPV is related to a number of cancer types, causing a considerable burden in both genders in Europe. Female vaccination programs can substantially reduce the incidence of HPV-related diseases in women and, to some extent, men through herd immunity. The objective was to estimate the incremental benefit of vaccinating boys and girls using the quadrivalent HPV vaccine in Europe versus girls-only vaccination. Incremental benefits in terms of reduction in the incidence of HPV 6, 11, 16 and 18-related diseases (including cervical, vaginal, vulvar, anal, penile, and head and neck carcinomas and genital warts) were assessed. The analysis was performed using a model constructed in Microsoft®Excel, based on a previously-published dynamic transmission model of HPV vaccination and published European epidemiological data on incidence of HPV-related diseases. The incremental benefits of vaccinating 12-year old girls and boys versus girls-only vaccination was assessed (70% vaccine coverage were assumed for both). Sensitivity analyses around vaccine coverage and duration of protection were performed. Compared with screening alone, girls-only vaccination led to 84% reduction in HPV 16/18-related carcinomas in females and a 61% reduction in males. Vaccination of girls and boys led to a 90% reduction in HPV 16/18-related carcinomas in females and 86% reduction in males versus screening alone. Relative to a girls-only program, vaccination of girls and boys led to a reduction in female and male HPV-related carcinomas of 40% and 65%, respectively and a reduction in the incidence of HPV 6/11-related genital warts of 58% for females and 71% for males versus girls-only vaccination. In Europe, the vaccination of 12-year old boys and girls against HPV 6, 11, 16 and 18 would be associated with substantial additional clinical benefits in terms of reduced incidence of HPV-related genital warts and carcinomas versus girls-only vaccination. The incremental benefits of adding boys vaccination are

    Little is known about the prevalence of human papillomavirus (HPV) infection in young adults in Asia. We invited female and male students in Busan, South Korea, to participate in a survey that included, for females, self-collection of vaginal cells and, for males, physician-performed collection of exfoliated genital cells. The prevalences of 25 HPV types were evaluated, by a polymerase chain reaction-based assay, in 672 female students (median age, 19 years) and in 381 male students (median age, 22 years). HPV DNA was detected more frequently in female students (15.2%) than in male students (8.7%); in both sexes, high-risk HPV types were predominant. Among sexually active students, HPV prevalence was 38.8% in females and 10.6% in males. In female students, currently smoking cigarettes and having multiple lifetime sex partners were the strongest risk factors for HPV infection; in male students, associations between HPV prevalence and sexual habits were similar to those in female students but never attained statistical significance. Young women in South Korea start having penetrative sexual intercourse relatively late (median age, 18 years), but, once they begin, HPV prevalence quickly rises to levels comparable with those found in university students in the United States and in northern Europe. The high rate of participation in our study suggests that trials of new vaccines against HPV may be feasible among university students in South Korea.

    Data from the National Health and Nutrition Examination Survey Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States (1). Some HPV types can cause genital warts and are considered low risk, with a small chance for causing cancer. Other types are considered high risk, causing cancer in different areas of the body including the cervix and vagina in women, penis in men, and anus and oropharynx in both men and women (2). This report provides the most recent national estimates of oral HPV prevalence among adults aged 18-69 from the National Health and Nutrition Examination Survey (NHANES) 2011-2014, as well as prevalence of genital HPV among adults aged 18-59 from NHANES 2013-2014. Estimates of any HPV (37 types tested) as well as high-risk HPV (14 of the 37 types) are provided.

    The aim of this study was to determine the cervical genotype profile of females who presented to an STI Clinic with external genital warts (EGW); and to determine the potential vaccine coverage prior to the uptake of the HPV vaccines. Sixty-one cervical scrapings were taken from females aged 18-35 y who had external genital warts or a history of external genital warts. The resulting 50 samples that were positive for HPV-DNA were subjected to genotype identification. Forty-six of these samples had detectable genotypes by LIPA analysis and most (78%, 36\\/46) had multiple low risk (LR) and high risk (HR) genotypes on the cervix. Twenty-five of these samples (54%) had more than 1 HR genotype. Of the 36 patients who had any HR genotypes, 18 (50%) were identified to have the most oncogenic HPV genotypes, namely 16 and 18. Three of these samples had both 16 and 18 on the cervix. The presence of multiple HR genotypes on the majority of cervical samples from a self-referred population of females with EGW is presented. This study is of importance since persistent HR-HPV is the necessary risk factor in the development of precancerous and cancerous lesions of the cervix. Gardisil, the quadrivalent HPV vaccine would have been useful in the prevention of 28% (13\\/46) of these infections.

    HPV vaccination in Singapore is voluntary and physician prescription-based. This study investigated the current status and intention for HPV vaccination among Singapore nurses. All female nurses in a general hospital were given an anonymous questionnaire on HPV vaccination experience and intention of vaccinating their daughters. The influence of age, knowledge and perceived-risk of cervical cancer, and cultural background on mother's intention of vaccinating their daughters was analyzed. Of 2,000 nurses, 1,622 (81.1%) responded and analysis was performed on 1,611 with valid data. They showed good awareness on association of cervical cancer with multiple sexual partners (81.9%), history of sexually transmissible diseases (78.2%), and history of genital warts/HPV infection (73.5%), and on cervical cancer preventive effects of HPV vaccination (54.6%). The prevailing misconceptions of the vaccines were: investigational nature (38.9%), side effects (27.9%) and indicated for women at high risk for cervical cancer (20.5%). Misconceptions on the nature, role and safety of HPV vaccines low vaccine up-take rates and daughters. Dissemination of adequate and accurate HPV vaccine information and a review for school-based vaccination are needed for optimal delivery of HPV vaccines in Singapore.

    The discovery of the human papillomavirus (HPV) vaccine illustrates the power of in situ-based pathologic analysis in better understanding and curing diseases. The 2 available HPV vaccines have markedly reduced the incidence of cervical intraepithelial neoplasias, genital warts, and cervical cancer throughout the world. Concerns about HPV vaccine safety have led some physicians, health care officials, and parents to refuse providing the recommended vaccination to the target population. The aims of the study were to discuss the discovery of HPV vaccine and review scientific data related to measurable outcomes from the use of HPV vaccines. The strong type-specific immunity against HPV in humans has been known for more than 25 years. Multiple studies confirm the positive risk benefit of HPV vaccination with minimal documented adverse effects. The most common adverse effect, injection site pain, occurred in about 10% of girls and was less than the rate reported for other vaccines. Use of HPV vaccine should be expanded into more diverse populations, mainly in low-resource settings. Copyright © 2015 Elsevier Inc. All rights reserved.

    Vaccines are available against human papillomavirus (HPV), the causal agent of cervical and other cancers. Efficacy data from the HPV-16/18 AS04-adjuvanted vaccine clinical trial program were reviewed. Six randomized, controlled phase II/III trials evaluating cervical endpoints enrolled women from diverse populations and geographical locations. The program analyzed extensively the cohorts most relevant from a public health perspective: the total vaccinated cohort (TVC), approximating a general population including those with existing or previous HPV infection, and TVC-naïve, approximating a population of young women before sexual debut. Results show that the vaccine reduces HPV-16/18 infection and associated cervical endpoints in women regardless of age, location, or sexual experience. It provides cross-protection against some non-vaccine oncogenic HPV types and types causing genital warts, and may be effective against vulvar, oral, and anal HPV infection. Early epidemiology data following its introduction suggest a decline in the prevalence of vaccine and some non-vaccine HPV types.

    No herpes simplex virus 2 (HSV-2) vaccine has been licensed for use in humans. HSV-2 glycoproteins B (gB) and D (gD) are targets of neutralizing antibodies and T cells, but clinical trials involving intramuscular (i.m.) injection of HSV-2 gB and gD in adjuvants have not been effective. Here we evaluated intravaginal (ivag) genetic immunization of C57BL/6 mice with a replication-defective human papillomavirus pseudovirus (HPV PsV) expressing HSV-2 gB (HPV-gB) or gD (HPV-gD) constructs to target different subcellular compartments. HPV PsV expressing a secreted ectodomain of gB (gBsec) or gD (gDsec), but not PsV expressing a cytoplasmic or membrane-bound form, induced circulating and intravaginal-tissue-resident memory CD8(+) T cells that were able to secrete gamma interferon (IFN-γ) and tumor necrosis factor alpha (TNF-α) as well as moderate levels of serum HSV neutralizing antibodies. Combined immunization with HPV-gBsec and HPV-gDsec (HPV-gBsec/gDsec) vaccines conferred longer survival after vaginal challenge with HSV-2 than immunization with HPV-gBsec or HPV-gDsec alone. HPV-gBsec/gDsec ivag vaccination was associated with a reduced severity of genital lesions and lower levels of viral shedding in the genital tract after HSV-2 challenge. In contrast, intramuscular vaccination with a soluble truncated gD protein (gD2t) in alum and monophosphoryl lipid A (MPL) elicited high neutralizing antibody titers and improved survival but did not reduce genital lesions and viral shedding. Vaccination combining ivag HPV-gBsec/gDsec and i.m. gD2t-alum-MPL improved survival and reduced genital lesions and viral shedding. Finally, high levels of circulating HSV-2-specific CD8(+) T cells, but not serum antibodies, correlated with reduced viral shedding. Taken together, our data underscore the potential of HPV PsV as a platform for a topical mucosal vaccine to control local manifestations of primary HSV-2 infection. Genital herpes is a highly prevalent chronic disease caused by

    The EUROGIN 2011 roadmap reviews the current burden of human papillomavirus (HPV)-related morbidity, as well as the evidence and potential practice recommendations regarding primary and secondary prevention and treatment of cancers and other disease associated with HPV infection. HPV infection causes ~600,000 cases of cancer of the cervix, vulva, vagina, anus and oropharynx annually, as well as benign diseases such as genital warts and recurrent respiratory papillomatosis. Whereas the incidence of cervical cancer has been decreasing over recent decades, the incidence of anal and oropharyngeal carcinoma, for which there are no effective screening programs, has been rising over the last couple of decades. Randomized trials have demonstrated improved efficacy of HPV-based compared to cytology-based cervical cancer screening. Defining the best algorithms to triage HPV-positive women, age ranges and screening intervals are priorities for pooled analyses and further research, whereas feasibility questions can be addressed through screening programs. HPV vaccination will reduce the burden of cervical precancer and probably also of invasive cervical and other HPV-related disease in women. Recent trials demonstrated that prophylactic vaccination also protects against anogenital HPV infection, anogenital intraepithelial lesions and warts associated with vaccine types, in males; and anal HPV infection and anal intraepithelial neoplasia in MSM. HPV-related oropharyngeal cancer could be treated less aggressively because of better survival compared to cancers of the oropharynx unrelated to HPV. Key findings in the field of cervical cancer prevention should now be translated in cost-effective strategies, following an organized approach integrating primary and secondary prevention, according to scientific evidence but adapted to the local situation with particular attention to regions with the highest burden of disease.

    Human Papillomavirus (HPV) is the main risk factor for cervical cancers and is associated with close to 36% of oropharyngeal cancers. There is increasing evidence that oral HPV transmission is related to sexual behavior but to our knowledge studies that involve women who have sex with women have not been performed. We examined the prevalence of oral HPV according to sexual behavior among a population-based sample of 118 women and have made some inferences of possible predictors of oral HPV infection. Women were categorized as heterosexual (history of vaginal sex and/or oral sex with males only, n = 75), bisexual (history of vaginal sex and oral sex with females, n = 32) and other (no history of vaginal sex but oral sex with females [homosexuals], virgins and women with incomplete sexual exposure data, n = 11) The prevalence of oral HPV infection was 12/118 (10.2%) for the overall study population and was not significantly different between heterosexual and bisexual women (10.7% (8/75) vs. 12.5% (4/32), p = 0.784). There was no oral HPV detected among homosexual women, virgins or among women where sexual exposure was unknown. Never smokers were more likely to be oral HPV+ compared to former smokers (Adjusted Odds Ratio (Adj OR) = 0.1, 95% CI, 0.0–1.1) and there was no difference in risk between never smokers and current smokers (Adj OR = 0.7, 95% CI, 0.1–4.6). Twenty-five percent (3/12) of oral HPV+ women had a history of HPV and/or genital warts compared to 9% (10/106) of oral HPV-women (p = 0.104). For the women with a history of vaginal sex (n = 110), oral HPV status was statistically significantly different according to oral sex exposure (p = 0.039). A higher proportion of oral HPV-positive women reported that they had no history of oral sex exposure compared to oral HPV-negative women (4/12, 33% vs. 7/98, 8%). The prevalence of cervical HPV infection did not vary between heterosexuals and bisexuals (35.7% (25/70) vs. 35.5% (11/31), p-value 0.411) and for

    Full Text Available Background In Canada, two vaccines that have demonstrated high efficacy against infection with human papillomavirus (HPV types −16 and −18 are available. The HPV-6/11/16/18 vaccine provides protection against genital warts (GW while the HPV-16/18 vaccine may provide better protection against other oncogenic HPV types. In this analysis, the estimated clinical and economic benefit of each of these vaccines was compared in the Canadian setting. Methods A Markov model of the natural history of HPV infection among women, cervical cancer (CC and GW was used to estimate the impact of vaccinating a cohort of 100,000 12-year-old females on lifetime outcomes and healthcare system costs (no indirect benefit in males included. A budget impact model was used to estimate the impact of each vaccine by province. Results In the base case, vaccination with the HPV-16/18 vaccine was predicted to prevent 48 additional CC cases, and 16 additional CC deaths, while vaccination with the HPV-6/11/16/18 vaccine was predicted to prevent 6,933 additional GW cases. Vaccination with the HPV-16/18 vaccine was estimated to save 1 additional discounted quality adjusted life year (QALY at an overall lower lifetime cost to the healthcare system compared to the HPV-6/11/16/18 vaccine (assuming vaccine price parity. In sensitivity analyses, the HPV-6/11/16/18 vaccine was associated with greater QALYs saved when the cross-protection efficacy of the HPV-16/18 vaccine was reduced, or the burden of GW due to HPV-6/11 was increased. In most scenarios with price parity, the lifetime healthcare cost of the strategy with the HPV-16/18 vaccine was predicted to be lower than the HPV-6/11/16/18 vaccine. In the probabilistic sensitivity analyses, the HPV-16/18 vaccine provided more QALY benefit than the HPV-6/11/16/18 vaccine in 49.2% of scenarios, with lower relative lifetime costs in 83.5% of scenarios. Conclusions Overall, the predicted lifetime healthcare costs and QALYs saved by

    Determination of epidemiologic features of genital HPV infection in women living in the Republic of Belarus, and detection of phylogenetic features of HPV-16. 1035 samples of epithelial cervix smears from patients with benign pathology, pre-cancer and cervix cancer were included into the study. 35 samples containing HPV-16 type DNAwere selected for sequencing. HPV L1 gene sequencing (300 n.p.) was performed by using 3100-Avant (Applied Biosystems). Sequencing results analysis was performed by using ClustalX (1.8) and BioEdit. MEGA 4.1 was used for phylogenetic analysis of the fragments obtained and tree construction. HPV-16 type is a dominant genotype that is responsible for the development of cervix cancer, its frequency of occurrence is 56.7% among patients with the specified pathology living in the Republic of Belarus. Predominance of East-Asian and European HPV-16 subtypes that can be attributed to a single evolutionary branch are the territorial features. At the same time detection of HPV-16 subtypes that have 0.003 - 0.007 p-distance between probes may indicate the presence of the several progenitors circulating in the country. A unique HPV-16 subtype was sequenced in the Gomel Region that could be one of the progenitors of HPV-16 circulating on the European continent. Further studies performed in the field of molecular epidemiology will allow to give a qualitative characteristic of the epidemic process, determine the direction and time of introduction of the virus into the country, control the circulation of the virus in the population.

    Full Text Available Abstract Background Infection with HPV 16 and 18, the major causative agents of cervical cancer, can be prevented through vaccination with a bivalent or quadrivalent vaccine. Both vaccines provide cross-protection against HPV-types not included in the vaccines. In particular, the bivalent vaccine provides additional protection against HPV 31, 33, and 45 and the quadrivalent vaccine against HPV31. The quadrivalent vaccine additionally protects against low-risk HPV type 6 and 11, responsible for most cases of genital warts. In this study, we made an analytical comparison of the two vaccines in terms of cost-effectiveness including the additional benefits of cross-protection and protection against genital warts in comparison with a screening-only strategy. Methods We used a Markov model, simulating the progression from HPV infection to cervical cancer or genital warts. The model was used to estimate the difference in future costs and health effects of both HPV-vaccines separately. Results In a cohort of 100,000 women, use of the bivalent or quadrivalent vaccine (both at 50% vaccination coverage reduces the cervical cancer incidence by 221 and 207 cases, corresponding to ICERs of €17,600/QALY and €18,900/QALY, respectively. It was estimated that the quadrivalent vaccine additionally prevents 4390 cases of genital warts, reducing the ICER to €16,300/QALY. Assuming a comparable willingness to pay for cancer and genital warts prevention, the difference in ICERs could justify a slightly higher price (~7% per dose in favor of the quadrivalent vaccine. Conclusions Clearly, HPV vaccination has been implemented for the prevention of cervical cancer. From this perspective, use of the bivalent HPV vaccine appears to be most effective and cost-effective. Including the benefits of prevention against genital warts, the ICER of the quadrivalent HPV vaccine was found to be slightly more favourable. However, current decision-making on the introduction of HPV

    Human papillomaviruses (HPV) are causally associated with ano-genital and a subset of head and neck cancers. Rising incidence of HPV+ anal cancers and head and neck cancers have now been demonstrated in the developed world over the last decade. The majority of published data on HPV prevalence at the anal and oro-pharyngeal sites are from studies of higher-risk populations. There is a paucity of data on the prevalence of HPV at non-cervical sites in lower risk, non-HIV+ women and this study was designed to provide initial pilot data on a population of women recalled for colposcopy as part of the UK cervical screening programme. 100 non-HIV+ women with abnormal cervical cytology, attending clinic for colposcopic examination were recruited. Swabs from the oro-pharyngeal, anal and cervical sites were taken and DNA extracted. HPV detection and genotyping were performed using a standardised, commercially available PCR-line blot assay, which is used to genotype 37 HPV subtypes known to infect the ano-genital and oro-pharyngeal areas. Strict sampling and laboratory precautions were taken to prevent cross-contamination. There was a very high prevalence of HPV infection at all three sites: 96.0%, 91.4% and 92.4% at the cervix, anus and oro-pharynx, respectively. Multiple HPV subtype infections were dominant at all 3 mucosal sites. At least one or more HR genotype was present at both the cervix/anus in 39/52 (75.0%) patients; both the cervix/oro-pharynx in 48/56 (85.7%) patients; and both the anus/oro-pharynx in 39/52 (75.0%) patients. HPV 16 infection was highly dominant across all mucosal sites, with over a 2-fold increase over the next most prevalent subtype (HPV 31). Women with abnormal smears have widespread infection with high-risk HPV at the cervical, anal and oro-pharyngeal mucosal sites and may represent a higher risk population for HPV disease in the future

    Human papillomavirus (HPV) infection remains one of the most commonly sexually transmitted infections in both females and males. HPV viruses are associated with several manifestations including genital warts, but more importantly for urology practitioners, cervical and penile carcinomas and recurrent genital condylomata in both sexes. The incidence of HPV-related carcinomas has increased in cervical, oropharyngeal, vulvar, penile, and anal cancers. Effective vaccines have been available for almost a decade, but widespread adoption of vaccine administration has been problematic for multiple reasons. Many countries (over 100) have adopted vaccine programs for females and an increasing number of countries are extending the indications to include males between the ages of 9-26. There still seems to be controversy surrounding these universal vaccination programs as well as some ethical and practical concerns regarding the administration of a vaccine for diseases that are associated with sexual contact in both sexes, especially during the early adolescent years. The objective was to provide a review of the available literature so pediatric and adult urologists may be more aware of the issues related to HPV vaccination in order to more effectively counsel patients and parents regarding the risks, benefits, and public health issues regarding HPV vaccination. This topic is especially relevant to pediatric urologists who see patients in the target age group for the HPV vaccine. There has been an explosion of literature regarding HPV vaccination programs and the relative difficulty in adopting the vaccine series with a completion rate of under 50% of patients in the recommended age ranges for vaccination. Articles were obtained from an extensive Medline literature search (1998-present) to evaluate the current HPV vaccination regimens for teenagers with special emphasis on the urologically focused disease burden. The adoption of universal HPV vaccination has been difficult

Effective vaccines have been available for almost a decade, but widespread adoption of vaccine administration has been problematic for multiple reasons. Many countries (over 100) have adopted vaccine programs for females and an increasing number of countries are extending the indications to include males between the ages of 9-26. There still seems to be controversy surrounding these universal vaccination programs as well as some ethical and practical concerns regarding the administration of a vaccine for diseases that are associated with sexual contact in both sexes, especially during the early adolescent years. Objective The objective was to provide a review of the available literature so pediatric and adult urologists may be more aware of the issues related to HPV vaccination in order to more effectively counsel patients and parents regarding the risks, benefits, and public health issues regarding HPV vaccination. This topic is especially relevant to pediatric urologists who see patients in the target age group for the HPV vaccine. There has been an explosion of literature regarding HPV vaccination programs and the relative difficulty in adopting the vaccine series with a completion rate of under 50% of patients in the recommended age ranges for vaccination. Methods Articles were obtained from an extensive Medline literature search (1998-present) to evaluate the current HPV vaccination regimens for teenagers with special emphasis on the urologically focused disease burden. Results The adoption of universal

    Genital herpes is a common sexually transmitted disease, affecting more than 400 million persons worldwide. It is caused by herpes simplex virus (HSV) and characterized by lifelong infection and periodic reactivation. A visible outbreak consists of single or clustered vesicles on the genitalia, perineum, buttocks, upper thighs, or perianal areas that ulcerate before resolving. Symptoms of primary infection may include malaise, fever, or localized adenopathy. Subsequent outbreaks, caused by reactivation of latent virus, are usually milder. Asymptomatic shedding of transmissible virus is common. Although HSV-1 and HSV-2 are indistinguishable visually, they exhibit differences in behavior that may affect management. Patients with HSV-2 have a higher risk of acquiring human immunodeficiency virus (HIV) infection. Polymerase chain reaction assay is the preferred method of confirming HSV infection in patients with active lesions. Treatment of primary and subsequent outbreaks with nucleoside analogues is well tolerated and reduces duration, severity, and frequency of recurrences. In patients with HSV who are HIV-negative, treatment reduces transmission of HSV to uninfected partners. During pregnancy, antiviral prophylaxis with acyclovir is recommended from 36 weeks of gestation until delivery in women with a history of genital herpes. Elective cesarean delivery should be performed in laboring patients with active lesions to reduce the risk of neonatal herpes.

    HPV and Chlamydia trachomatis are the most common causes of sexually transmitted diseases worldwide. Most infections are asymptomatic and left untreated lead to severe reproductive tract sequelae such as cervical cancer and infertility. Interestingly, C. trachomatis may also increase the susceptibility to HPV infection as well as contribute to viral persistence. Recently, a growing body of evidence has suggested that the composition of the cervico-vaginal microbiota plays a key role in the susceptibility and outcome of genital infections caused by several pathogens, including HPV and C. trachomatis. The aim of our study was to undertake a metagenomic analysis of sequenced 16s rRNA gene amplicons to characterize the cervical microbiota from asymptomatic women with HPV/C. trachomatis co-infection. The composition of the cervical microbiota from HPV-positive or C. trachomatis-positive women was also analysed. The main finding of our study showed that the cervical microbiota in HPV/C. trachomatis co-infected women had a higher microbial diversity than the cervical microbiota in healthy controls (pHPV/C. trachomatis co-infected women and the detection of potential microbiological biomarkers of C. trachomatis infection will open the way to innovative approaches that may be helpful to identify women at risk of co-infection.

    Full Text Available No study has estimated the potential impact of Human Papillomavirus (HPV vaccination in Puerto Rico, a population with considerable burden of HPV-related morbidities. We evaluated the health and economic impacts of implementing a vaccination strategy for females and males in Puerto Rico, with the quadrivalent HPV (HPV4 vaccine, under different vaccination scenarios.We adapted a mathematical model which estimates the direct and indirect health benefits and costs of HPV4 vaccination in a dynamic population. The model compared three vaccination scenarios against screening only (no-vaccination for three doses of HPV4 vaccine among individuals aged 11-15 years in Puerto Rico: 1 34% for females and 13% for males (34%F/13%M, 2 50% for females and 40% for males (50%F/40%M, and 3 80% for female and 64% for male (80%F/64%M. Data specific to Puerto Rico was used. When not available, values from the United States were used. Input data consisted of demographic, behavioral, epidemiological, screening, and economic parameters.The model predicted decreases in: 1 HPV infection prevalence for females and males, 2 cervical intraepithelial neoplasia and cervical cancer incidence for females, 3 genital warts incidence for females and males, and 4 cervical cancer deaths among females, when various vaccination program scenarios were considered. In addition, when the vaccination percentage was increased in every scenario, the reduction was greater and began earlier. The analysis also evidenced an incremental cost effectiveness ratio (ICER of $1,964 per quality-adjusted life year gained for the 80%F/64%M uptake scenario.HPV vaccine can prove its cost effectiveness and substantially reduce the burden and costs associated to various HPV-related conditions when targeted to the adequate population together with an organized HPV vaccination program.

    Human papillomavirus (HPV) vaccines provide an opportunity to reduce the incidence of cervical cancer. Optimization of cervical cancer prevention programs requires anticipation of the degree to which the public will adhere to vaccination recommendations. To compare vaccination levels driven by public perceptions with levels that are optimal for maximizing the community's overall utility, we develop an epidemiological game-theoretic model of HPV vaccination. The model is parameterized with survey data on actual perceptions regarding cervical cancer, genital warts, and HPV vaccination collected from parents of vaccine-eligible children in the United States. The results suggest that perceptions of survey respondents generate vaccination levels far lower than those that maximize overall health-related utility for the population. Vaccination goals may be achieved by addressing concerns about vaccine risk, particularly those related to sexual activity among adolescent vaccine recipients. In addition, cost subsidizations and shifts in federal coverage plans may compensate for perceived and real costs of HPV vaccination to achieve public health vaccination targets.

  13. [Immunity of the female genital tract mucosa and mechanisms of papillomavirus evasion].

    Science.gov (United States)

    Riethmuller, D; Seilles, E

    2000-12-01

    Human papillomaviruses (HPV) are responsible for many cutaneous and mucosal lesions. Some viral genotypes are considered to be the causal agents of cervical cancer. Natural genital HPV infection seems to be poorly immunogenic because of its nonproductive and noninflammatory characteristics and also because of the different mechanisms developed by the virus to counteract the immune response. Knowledge of the immune system organization and its regulation in the human female genital tract needs to be clarified. It is mostly "programmed" to ensure a humoral response. Nevertheless, secretory IgA, that are particularly efficient for anti-infectious mucosal immunity are poorly present in physiological vaginal secretions. These distinctive features could explain part of the relative immune deficiency against HPV. Moreover, reduction or loss of MCH1 molecules and a defect in antigen presentation to cytotoxic lymphocytes could in part explain the cytotoxicity deficiency. There is however clear evidence that cellular immune response plays a major role in the control and course of HPV infection. This response varies according to the grade of the lesion and to the oncogenic potential of the infecting HPV. A deficiency in induction of cellular cytotoxicity mechanisms seems to be involved in the persistence of HPV infection and so in carcinogenesis. Finally, worldwide cervical cancer incidence (5000000 new cases per year) warrants effective vaccine developments. Two strategies, one preventive and one therapeutic, are now under study. Vaccine adjustments are based first on humoral immunity induction with production of neutralizing antibodies for prophylaxis and second on cellular immunity induction to kill cells with viral oncoprotein expression for therapy.

    Approximately 80% of cervical cancer cases occur in developing countries. In Thailand, cervical cancer has been the leading cancer in females, with an incidence of 24.7 cases per 100,000 individuals per year. We constructed a decision model to simulate the lifetime economic impact for women in the context of human papillomavirus (HPV) infection prevention. HPV-related diseases were of interest: cervical cancer, cervical intraepithelial neoplasia, and genital warts. The two strategies used were 1) current practice and 2) prophylactic quadrivalent vaccine against HPV types 6, 11, 16, and 18. We developed a Markov simulation model to evaluate the incremental cost-effectiveness ratio of prophylactic HPV vaccine. Women transition through a model either healthy or developing HPV or its related diseases, or die from cervical cancer or from other causes according to transitional probabilities under the Thai health-care context. Costs from a provider perspective were obtained from King Chulalongkorn Memorial Hospital. Costs and benefits were discounted at 3% annually. Compared with no prophylactic HPV vaccine, the incremental cost-effectiveness ratio was 160,649.50 baht per quality-adjusted life-year. The mortality rate was reduced by 54.8%. The incidence of cervical cancer, cervical intraepithelial neoplasia grade 1, cervical intraepithelial neoplasia grade 2/3, and genital warts was reduced by up to 55.1%. Compared with commonly accepted standard thresholds recommended by the World Health Organization Commission on Macroeconomics and Health, the nationwide coverage of HPV vaccination in girls is likely to be cost-effective in Thailand.

    Genital warts are caused by human papillomavirus infection and represent one of the most common sexually transmitted diseases. Many infections are transient but the virus may recur, persist, or become latent. To date, there is no effective antiviral treatment to eliminate HPV infection and most therapies are aimed at the destruction of visible lesions. Potassium hydroxide is a strong alkali that has been shown to be safe and effective for the treatment of genital warts and molluscum contagiosum. Cryotherapy is considered one of the most established treatments for genital warts. No comparative trials have been reported to date on the use of potassium hydroxide for genital warts. A prospective, open-label, randomized clinical trial was conducted to compare topical potassium hydroxide versus cryotherapy in the treatment of genital warts affecting immunocompetent, sexually active men. Over a period of 10 months, 48 patients were enrolled. They were randomly divided into two groups and selected on an alternative basis for either potassium hydroxide therapy or cryotherapy. While response to therapy did not differ substantially between both treatment modalities, side effects such as local pain and post-treatment hypopigmentation were considerably more prevalent in the groups treated using cryotherapy. In our study, potassium hydroxide therapy proved to be at least as effective as cryotherapy and offered the benefit of a better safety profile. Topical 5% potassium hydroxide presents an effective, safe, and low-cost treatment modality for genital warts in men and should be included in the spectrum of therapies for genital warts.

    Persistent oncogenic human papillomavirus (HPV) is the cause of cervical cancer, as well as cancers of the anus, penis, vulva, vagina and oropharynx. There is good evidence that prophylactic HPV vaccines are immunogenic and effective against targeted-type HPV infections and type-specific genital lesions, including high-grade cervical intraepithelial neoplasia (CIN), when administered prior to HPV infection. There is good evidence that HPV vaccines are safe in population usage, with the most frequent adverse event being injection-site reactions. There is evidence to support some cross-protection against non-targeted types occurring following the administration of HPV vaccines. There is limited evidence suggesting that HPV vaccines may be beneficial in preventing future disease in women treated for high-grade CIN. This chapter focuses on the accumulated evidence regarding the global use of the three licensed HPV vaccines including safety, immunogenicity, duration of protection, effectiveness, coverage to date and barriers to higher coverage.

    The aim of this study was to systematically review the findings of publications addressing the epidemiology of anal human papillomavirus (HPV) infection, anal intraepithelial neoplasia, and anal cancer in women. We conducted a systematic review among publications published from Jan. 1, 1997, to Sept. 30, 2013, to limit to publications from the combined antiretroviral therapy era. Three searches were performed of the National Library of Medicine PubMed database using the following search terms: women and anal HPV, women anal intraepithelial neoplasia, and women and anal cancer. Publications were included in the review if they addressed any of the following outcomes: (1) prevalence, incidence, or clearance of anal HPV infection, (2) prevalence of anal cytological or histological neoplastic abnormalities, or (3) incidence or risk of anal cancer. Thirty-seven publications addressing anal HPV infection and anal cytology remained after applying selection criteria, and 23 anal cancer publications met the selection criteria. Among HIV-positive women, the prevalence of high-risk (HR)-HPV in the anus was 16-85%. Among HIV-negative women, the prevalence of anal HR-HPV infection ranged from 4% to 86%. The prevalence of anal HR-HPV in HIV-negative women with HPV-related pathology of the vulva, vagina, and cervix compared with women with no known HPV-related pathology, varied from 23% to 86% and from 5% to 22%, respectively. Histological anal high-grade squamous intraepithelial lesions (anal intraepithelial neoplasia 2 or greater) was found in 3-26% of the women living with HIV, 0-9% among women with lower genital tract pathology, and 0-3% for women who are HIV negative without known lower genital tract pathology. The incidence of anal cancer among HIV-infected women ranged from 3.9 to 30 per 100,000. Among women with a history of cervical cancer or cervical intraepithelial neoplasia 3, the incidence rates of anal cancer ranged from 0.8 to 63.8 per 100,000 person-years, and in

    The prevalent human papillomaviruses (HPVs) infect human epithelial tissues. Infections by the mucosotropic HPV genotypes cause hyperproliferative ano-genital lesions. Persistent infections by high-risk (HR) HPVs such as HPV-16, HPV-18 and related types can progress to high grade intraepithelial neoplasias and cancers. Prophylactic HPV vaccines are based on DNA-free virus-like particles (VLPs) composed of the major capsid protein L1 of HPV-16, -18, -6 and -11 (Gardasil) or HPV-16 and -18 (Cervarix). Sera from vaccinated animals effectively prevent HPV pseudovirions to infect cell lines and mouse cervical epithelia. Both vaccines have proven to be highly protective in people. HPV pseudovirions are assembled in HEK293TT cells from matched L1 and L2 capsid proteins to encapsidate a reporter gene. Pseudovirions and genuine virions have structural differences and they infect cell lines or primary human keratinocytes (PHKs) with different efficiencies. In this study, we show that sera and isolated IgG from women immunized with Gardasil prevent authentic HPV-18 virions from infecting PHKs, whereas non-immune sera and purified IgG thereof are uniformly ineffective. Using early passage PHKs, neutralization is achieved only if immune sera are added within 2-4h of infection. We attribute the timing effect to a conformational change in HPV virions, thought to occur upon initial binding to heparan sulfate proteoglycans (HSPG) on the cell surface. This interpretation is consistent with the inability of immune IgG bound to or taken up by PHKs to neutralize the virus. Interestingly, the window of neutralization increases to 12-16h in slow growing, late passage PHKs, suggestive of altered cell surface molecules. In vivo, this window might be further lengthened by the time required to activate the normally quiescent basal cells to become susceptible to infection. Our observations help explain the high efficacy of HPV vaccines. Copyright © 2016 Elsevier Ltd. All rights reserved.

    High-risk human papillomaviruses (HR-HPV) are the cause of most ano-genital cancers and a fast growing subset of oropharyngeal cancer. As these malignancies occur as a result of an HPV- infection transmitted through intimate contact, many patients with HPV- induced cancer and their partners are concerned about HPV-transmission and the potential partners' cancer risk. Few studies have addressed this issue and whether the HPV-related cancer risk of partners of patients with HPV-related cancers is comparable to or greater than that of the general population. We performed a systematic review of the published literature addressing this issue. Out of 1055 references screened, 53 articles were found eligible for inclusion. Regarding the issue of coincidence of HPV-induced oropharyngeal and/or anogenital cancers in couples, 13 case-reports or case-series were reported and 9 larger studies based on population-registries. Four of these registry studies showed an increased risk of cervical cancer in the partner while four did not. Among the four positive studies, odds ratios for the development of HPV-related cancer among spouses were between 2.6 and 6.7. One study showed an increased risk of tongue or tonsil cancer among husbands of women with cervical dysplasia or cancer. Overall the absolute risk increase in all these studies was small, on the order of 1-3%, although potentially underestimated. Indeed, all these studies have assessed partner's cancer risk at only one anatomical site whereas HPV- related malignancies can affect different locations. This systematic review suggests a small trend of increase risk in HPV-associated cancers among spouses of patients with HPV-related cancer. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Human Papillomavirus (HPV infection is the most prevalent sexually-transmitted virus worldwide. It is known to be the etiological agent of cervical cancer and cervical intraepithelial neoplasia (CIN. Consequently, there is strong motivation to evaluate HPV testing in cervical cancer screening. Recently developed, the second generation of the hybrid capture test (HCA II is a non-radioactive, relatively rapid, hybridization assay, designed to detect 18 HPV types divided into high and low-risk groups. We evaluated 7,314 patients (5,833 women and 1,481 men for HPV infection by HCA II. Among them, 3,008 (41.1% presented HPV infection: 430 (14.2% had HPV DNA of low risk for cancer, 1,631 (54.2% had high risk HPV types and 947 (31.5% had both types. The prevalence in females was 44.9%. The prevalence of HPV DNA in the group for which cytological results were available was slightly higher: 55.3% (1007/1824. Significant differences were detected in the frequency of HPV infection of the cervix between normal cases and those with high-grade squamous-intraepithelial lesions (HSIL(P<0.0001. Among males, the prevalence was 26.2%, composed of 9.1% in Group A, 9.7% in Group B and 7.4% with multiple infections. We observed that male prevalence was lower and that low-risk types were more frequent than in females. HPV viral load was significantly greater in SILs than in normal or inflammatory cases (P<0.0001, suggesting an association between high viral load values and risk of SIL. Because of high costs, the HCA II test cannot be recommended for routine mass screening for cervical infection in poor countries. Nevertheless, it was found to be a useful tool, when combined with cytology, discovering high-risk infections in apparently normal tissues and revealing silent infections that may be responsible for the maintenance of HPV in the general population. These findings point to the need for close and careful management of patients, thereby reducing overtreatment

    Human Papillomavirus (HPV) is a major cause of cervical cancer, precancerous lesions, cancer and other disease. HPV is the most common sexually transmitted infection. Although HPV virus primarily affects woman but it can also affects man because it cause of cancer of the anus, vulva, vagina, penis and some other cancers. HPV vaccines now used to prevent cervical cancer and genital warts because the vaccine protect against four types of HPV that most commonly cause disease are types 6, 11, 16, and 18. This paper is sequel work of Elbasha (2008). Difference with Elbasha (2008) are give alternative proof global stability, numerical simulation and interpretation. Global stability of the equilibrium on the model of a two-sex HPV vaccination were explored by using Lyapunov. Although we use the same lyapunov function, we use the largest invariant set to proof the global stability. The result show that the global stability of the equilibrium depends on the effective reproduction number (R). If R 1 then endemic equilibrium have globally asymptotically stable properties. Then equilibrium proceed with the interpretation of numerical simulation.

    2016-01-01

    Full Text Available Controversy still exists over whether the benefits of the available HPV vaccines outweigh the risks and this has suppressed uptake of the HPV vaccines in comparison to other vaccines. Concerns about HPV vaccine safety have led some physicians, healthcare officials and parents to withhold the recommended vaccination from the target population. The most common reason for not administering the prophylactic HPV vaccines are concerns over adverse effects. The aim of this review is the assessment of peer-reviewed scientific data related to measurable outcomes from the use of HPV vaccines throughout the world with focused attention on the potential adverse effects. We found that the majority of studies continue to suggest a positive risk-benefit from vaccination against HPV, with minimal documented adverse effects, which is consistent with other vaccines. However, much of the published scientific data regarding the safety of HPV vaccines appears to originate from within the financially competitive HPV vaccine market. We advocate a more independent monitoring system for vaccine immunogenicity and adverse effects to address potential conflicts of interest with regular systematic literature reviews by qualified individuals to vigilantly assess and communicate adverse effects associated with HPV vaccination. Finally, our evaluation suggests that an expanded use of HPV vaccine into more diverse populations, particularly those living in low-resource settings, would provide numerous health and social benefits.

  15. Male genital trauma

    We have attempted to discuss genital trauma in relatively broad terms. In most cases, patients present with relatively minimal trauma. However, because of the complexity of the structures involved, minimal trauma can lead to significant disability later on. The process of erection requires correct functioning of the arterial, neurologic, and venous systems coupled with intact erectile bodies. The penis is composed of structures that are compliant and distensible to the limits of their compliance. These structures therefore tumesce in equal proportion to each other, allowing for straight erection. Relatively minimal trauma can upset this balance of elasticity, leading to disabling chordee. Likewise, relatively minimal injuries to the vascular erectile structures can lead to significantly disabling spongiofibrosis. The urethra is a conduit of paramount importance. Whereas the development of stricture is generally related to the nature of the trauma, the extent of stricture and of attendant complications is clearly a function of the immediate management. Overzealous debridement can greatly complicate subsequent reconstruction. A delicate balance between aggressive initial management and maximal preservation of viable structures must be achieved. 38 references

    The 9-valent HPV (9vHPV) vaccine was developed to prevent infection and disease related to 9 HPV types (HPV6/11/16/18/31/33/45/52/58) which cause approximately 90% of cervical cancers, HPV-related vulvar, vaginal and anal cancers, and genital warts worldwide. In a pivotal efficacy study, the 9vHPV vaccine prevented infection and disease due to the 9 vaccine types. Duration of protection remains to be determined. Vaccines that induce long-term protection are generally characterized by the generation of immune memory. The purpose of this report is to assess the persistence of HPV antibody response and existence of immune memory at 5years post-vaccination. A subset of subjects (N=150) who received 3 doses of 9vHPV vaccine at day 1, month 2 and month 6 in the pivotal efficacy study continued in a study extension and received a fourth dose of 9vHPV vaccine at month 60. Serum HPV antibody levels were measured pre-dose 4 and at 7 and 28days post-dose 4 by competitive Luminex immunoassay. Adverse events were assessed using a vaccination report card. HPV antibodies induced following the 3-dose series of 9vHPV vaccine in the base study persisted through month 60 with seropositivity rates ranging from 77.5% to 100%. Geometric mean titers at 1week and 1month post-dose 4 were 1.25-4.10 and 1.65-4.88-fold higher, respectively, than levels observed 1month following the completion of the three-dose primary series. Seropositivity rates were >99% and 100% at 1week and 1month post-dose 4, respectively. The fourth dose of 9vHPV vaccine was generally well tolerated. A three-dose regimen of the 9vHPV vaccine induced persistent HPV antibody response through 5years post-vaccination. Administration of a fourth dose resulted in a strong anamnestic response to all 9 vaccine types. These findings suggest that the efficacy of the 9vHPV vaccine will be long lasting.

    2017-08-01

    College students suffer disproportionately from human papillomavirus (HPV), a sexually transmitted infection (STI) that could result in genital warts or cancers in both males and females. Research contends that stigma and shame may serve as barriers to disclosure intentions, as well as vaccination intentions. The goal of this study was to examine whether two framing strategies-whether to mention that HPV is sexually transmitted and whether to highlight the cause of infection as internal or external-would influence young adults' intentions to disclose a potential diagnosis and their intentions to get the recommended HPV vaccine. Results indicate that STI framing and gender had consistent impacts on disclosure and vaccination intentions. Further, causal attribution framing also influenced participants' intention to get the vaccine at no cost immediately and their intention to get the vaccine at the retail price of $375 in the future. Theoretical and practical implications of these results are discussed.

    The new human papillomavirus (HPV) vaccine is a research breakthrough for pediatric/adolescent health to prevent cervical cancer and related morbidity. The annual heath care cost for the treatment of cervical cancer and genital warts is estimated to be more than three billion dollars a year. The new HPV vaccine has incredible potential to improve reproductive health promotion, reduce health care costs, and close health care disparity gaps. However, issues both for and against the new HPV vaccine, including mandating vaccination, high cost of the vaccine, the short duration of protection offered, and the perceived promotion of sexual activity, cause confusion. Pediatric nurses, including those in advanced practice, benefit by understanding the pros and cons of these issues in advocating for their patients.

    2017-11-01

    Full Text Available ABSTRACT CONTEXT: Myiasis is caused by larval infestation that usually occurs in exposed wounds. Dermatobia hominis is the most common fly species responsible for this parasitic infection. Genital piercing is an ornamental practice used in certain social circles. At placement, it transverses the skin surface and, as such, may be related to complications. CASE REPORT: We report a case of a 31-year-old man with a history of wound infection secondary to genital piercing who was exposed to an environment with flies, leading to myiasis. Mechanical removal and systemic antiparasitic drugs are possible treatments for myiasis. However, prevention that includes wound cleaning and dressing is the best way to avoid this disease. CONCLUSIONS: Genital piercing can lead to potential complications and myiasis may occur when skin lesions are not properly treated.

    Full Text Available The species Alphapapillomavirus 7 (alpha-7 contains human papillomavirus genotypes that account for 15% of invasive cervical cancers and are disproportionately associated with adenocarcinoma of the cervix. Complete genome analyses enable identification and nomenclature of variant lineages and sublineages.The URR/E6 region was sequenced to screen for novel variants of HPV18, 39, 45, 59, 68, 70, 85 and 97 from 1147 cervical samples obtained from multiple geographic regions that had previously been shown to contain an alpha-7 HPV isolate. To study viral heterogeneity, the complete 8 kb genome of 128 isolates, including 109 sequenced for this analysis, were annotated and analyzed. Viral evolution was characterized by constructing phylogenic trees using maximum-likelihood and Bayesian algorithms. Global and pairwise alignments were used to calculate total and ORF/region nucleotide differences; lineages and sublineages were assigned using an alphanumeric system. The prototype genome was assigned to the A lineage or A1 sublineage.The genomic diversity of alpha-7 HPV types ranged from 1.1% to 6.7% nucleotide sequence differences; the extent of genome-genome pairwise intratype heterogeneity was 1.1% for HPV39, 1.3% for HPV59, 1.5% for HPV45, 1.6% for HPV70, 2.1% for HPV18, and 6.7% for HPV68. ME180 (previously a subtype of HPV68 was designated as the representative genome for HPV68 sublineage C1. Each ORF/region differed in sequence diversity, from most variable to least variable: noncoding region 1 (NCR1 / noncoding region 2 (NCR2 > upstream regulatory region (URR > E6 / E7 > E2 / L2 > E1 / L1.These data provide estimates of the maximum viral genomic heterogeneity of alpha-7 HPV type variants. The proposed taxonomic system facilitates the comparison of variants across epidemiological and molecular studies. Sequence diversity, geographic distribution and phylogenetic topology of this clinically important group of HPVs suggest an independent evolutionary

    Full Text Available Abstract Background Cervical cancer is the second most common cancer among women in Brazil. We examined the health and economic impacts of quadrivalent HPV vaccination in Brazil. Methods We adapted a previously developed transmission dynamic model to estimate the effectiveness of HPV vaccination on cervical cancer, cervical intraepithelial neoplasia grades 2 and 3 (CIN2/3, CIN1, and genital warts. We evaluated following vaccination strategies: routine vaccination of 12-year-old girls and routine vaccination in combination with a catch-up vaccination of 12 to 26-year-old women. Results The model projected that the vaccination would reduce the incidence rates of HPV 6/11/16/18-related cervical cancer, CIN2/3, CIN1, and female genital warts by 94% to 98% at year 100. Routine vaccination in combination with a catch-up vaccination could prevent approximately 163,000 cases of cervical cancer, 48,000 deaths from cervical cancer, 2.3 million cases of CIN2/3, and 11.4 million genital warts in the next 50 years. The incremental cost-effectiveness ratios for female vaccination strategies ranged from R$350 to R$720 (US$219 to US$450 per quality-adjusted life year (QALY gained. Conclusions Our study demonstrates that quadrivalent HPV female vaccination can be a cost-effective public health intervention that can substantially reduce the burden of cervical diseases and genital warts in Brazil.

    Full Text Available Abstract Background Genital Human papilloma virus (HPV is one of the most commonly diagnosed Sexually Transmitted Infection (STIs in men and women. Knowledge about HPV infection among men is limited. This study aims to determine correlates of adequate knowledge of HPV infection among men who attend an STI clinic in Puerto Rico. Methods A cross-sectional study of 206 men was conducted at an STI clinic in San Juan, PR. Adequate knowledge was defined as a score of at least 70% of correct responses among those men who reported having ever heard of HPV. Variables that achieved statistical significance in the bivariate analysis (p Results Although 52.5% of men reported having heard of HPV infection before the survey, only 29.3% of this sub-group had an adequate knowledge of HPV. Most men did not know that HPV is a risk factor for anal (38.7%, penile (50.0% and oral (72.6% cancer. Factors associated with adequate knowledge of HPV in age-adjusted models were being men who have sex with men (MSM (OR=2.6;95%CI=1.1-6.1, self-report of genital warts (OR=3.2;95%CI=1.3-7.9 and herpes (OR=7.4;95% CI=2.2-25.1. MSM was marginally associated with adequate knowledge (OR=2.3;95% CI=0.9-5.9 and self-report of herpes remained significantly associated (OR=5.0;95%CI=1.3-18.4 in multivariate logistic regression analysis. Conclusions Awareness and knowledge of HPV was very low in this group of men. Interventions to increase knowledge and awareness in this group are necessary to promote preventive practices for HPV-related cancers in high-risk groups.

  6. Chlamydia trachomatis Genital Infections

    Catherine M. O’Connell

    2016-09-01

    Full Text Available Etiology, transmission and protection: Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infection (STI globally. However, C. trachomatis also causes trachoma in endemic areas, mostly Africa and the Middle East, and is a leading cause of preventable blindness worldwide. Epidemiology, incidence and prevalence: The World Health Organization estimates 131 million new cases of C. trachomatis genital infection occur annually. Globally, infection is most prevalent in young women and men (14-25 years, likely driven by asymptomatic infection, inadequate partner treatment and delayed development of protective immunity. Pathology/Symptomatology: C. trachomatis infects susceptible squamocolumnar or transitional epithelial cells, leading to cervicitis in women and urethritis in men. Symptoms are often mild or absent but ascending infection in some women may lead to Pelvic Inflammatory Disease (PID, resulting in reproductive sequelae such as ectopic pregnancy, infertility and chronic pelvic pain. Complications of infection in men include epididymitis and reactive arthritis. Molecular mechanisms of infection: Chlamydiae manipulate an array of host processes to support their obligate intracellular developmental cycle. This leads to activation of signaling pathways resulting in disproportionate influx of innate cells and the release of tissue damaging proteins and pro-inflammatory cytokines. Treatment and curability: Uncomplicated urogenital infection is treated with azithromycin (1 g, single dose or doxycycline (100 mg twice daily x 7 days. However, antimicrobial treatment does not ameliorate established disease. Drug resistance is rare but treatment failures have been described. Development of an effective vaccine that protects against upper tract disease or that limits transmission remains an important goal.

    Complete genomes of HPV101 and HPV103 were PCR amplified and cloned from cervicovaginal cells of a 34-year-old female with cervical intraepithelial neoplasia grade 3 (CIN 3) and a 30-year-old female with a normal Pap test, respectively. HPV101 and HPV103 contain 4 early genes (E7, E1, E2 and E4) and 2 late genes (L2 and L1), but both lack the canonical E6 ORF. Pairwise alignment similarity of the L1 ORF nucleotide sequences of HPV101 and HPV103 indicated that they are at least 30 % dissimilar to each other and all known PVs. However, similarities of the other ORFs (E7, E1, E2, and L2) indicated that HPV101 and HPV103 are most related to each other. Phylogenetic analyses revealed that these two types form a monophyletic clade, clustering together with the gamma- and pi-PV groups. These data demonstrated that HPV genomes closely related to papillomaviruses identified from cutaneous epithelia can be isolated from the genital mucosal region. Moreover, this is the first report of HPVs lacking an E6 ORF and phylogenetic evidence suggests this occurred subsequent to their emergence from the gamma-/pi-PVs. PMID:17125811

    Restriction fragment length polymorphism (RFLP) methods for genotyping genital human papillomavirus (HPV) are considered labor consuming and constrained by the reduced set of restriction enzymes capable of detecting specific mutations. However, we think that these methods have not taken full advantage of the high diversity of the known restriction enzymes. We have set out to find the best restriction enzyme for HPV typing. An extensive search for enzymes was carried out by combining statistical methods and database information. The search maximized the discrimination between high- and low-risk types by examining the sequence of the L1 gene flanked by primers MY09/11. Different electrophoretic resolutions and two variations of the RFLP method were considered. HpyCH4V is the best enzyme for discriminating between risk types. Moreover, HpyCH4V generates different patterns for virtually all the HPV types. The typical pattern consists of two or three fragments, which facilitates typing in mixed infections. The typing of a set of clinical samples confirmed the expectations. This result illustrates the possibilities of statistical methods to exploit the high diversity of restriction enzymes in order to classify samples in a pre-established hierarchy of types for which DNA sequences are known.

    Prophylactic HPV vaccines target young adolescents to prevent related cervical lesions and even genital warts prior to onset of sexual activity. Parental consent is often essential for success of vaccination program for this age group. We conducted a national multicenter study to explore the acceptability of HPV vaccination among parents of young adolescents and associated factors in relevant parent decision making in China. A total of 2899 parents of young adolescents (11-17 years) participated in the survey between November 28, 2011 and May 9, 2012, but four were excluded from analysis because of inconsistencies in their given information in the questionnaire. Mothers accounted for 62.8% of the parent participants. The mean age of the parents was 40.40 (standard deviation, 4.68) years. Only 36.2% of the parents accepted the vaccine for their children. Knowledge about HPV and HPV vaccine was a positive correlate with HPV vaccination acceptability (Ptrend=0.003). Grade of child (Ptrend=0.015), prior vaccination experience outside the National Expanded Program on Immunization (OR: 1.43; 95%CI: 1.19-1.72), fear of cervical cancer and/or genital warts (OR: 2.47; 95%CI: 2.00-3.05), and prior consultation regarding HPV vaccine information (OR: 2.35; 95%CI: 1.57-3.52) were also positively associated with higher HPV vaccine acceptability. The acceptability was lower in mothers (OR: 0.45; 95%CI: 0.37-0.54) and who had better education (Ptrend=0.009). 57.3% of the parents agreed that the most appropriate venue for HPV vaccination was the local center for disease prevention and control. In conclusion, our study indicates a low acceptability of HPV vaccination among parents of young adolescents in China. We understand there are many challenges in implementing HPV vaccination program. Our findings will serve as valuable references for future HPV vaccination policies and campaigns after HPV vaccines are approved in China. Copyright © 2013 Elsevier Ltd. All rights reserved.

  11. Female genital mutilation in Djibouti.

    2012-12-01

    The practice of female genital mutilation (we will use the latest definition adopted by WHO/UNFP: female genital mutilation/cutting or FGM/C) is still widespread in 28 African countries. The World Health Organisation (WHO) estimates that more than two million females undergo some form of genital mutilation every year. Its negative health impact and its ethical and human rights aspects have been discussed and attempts to eliminate it have been the objectives of several meetings promoted by national and international organisations thanks to an increased awareness related to FGM/C in those countries practicing it and also, maybe due to the number of Africans migrating to industrialized countries. We review the present situation in Djibouti, a small country in the Horn of Africa, where 98 % of the female population has suffered different forms of FGM/C.

    The aim of the present population-based cohort study was to analyze the association between the prevalence of 32 types of human papilloma virus (HPV) in 615 female patients with abnormal cervical cytopathology findings. In total, 32 HPV types were screened by DNA array technology. HPV infection was detected in 470 women (76.42%), 419 of whom (89.15%) were infected with ≥1 high-risk (HR)-HPV type. HPV16, which is recognized as the main HR-HPV type responsible for the development of cervical cancer, was observed in 32.98% of HPV + participants, followed by HPV42 (18.09%), HPV31 (17.66%), HPV51 (13.83%), HPV56 (10.00%), HPV53 (8.72%) and HPV66 (8.72%). The prevalence of HR-HPV types, which may be suppressed directly (in the case of HPV16 and 18), or possibly via cross-protection (in the case of HPV31) following vaccination, was considerably lower in participants ≤22 years of age (HPV16, 28.57%; HPV18, 2.04%; HPV31, 6.12%), compared with participants 23-29 years of age (HPV16, 45.71%; HPV18, 7.86%; HPV31, 22.86%), who were less likely to be vaccinated. Consequently, the present study hypothesizes that there may be a continuous shift in the prevalence of HPV types as a result of vaccination. Furthermore, the percentage of non-vaccine HR-HPV types was higher than expected, considering that eight HPV types formerly classified as 'low-risk' or 'probably high-risk' are in fact HR-HPV types. Therefore, it may be important to monitor non-vaccine HPV types in future studies, and an investigation concerning several HR-HPV types as risk factors for the development of cervical cancer is required.

    The SW756 cell line, derived from an invasive cancer of the uterine cervix, harbours integrated human papillomavirus (HPV) 18 DNA sequences which have been located in chromosome band 12q13. By in situ hybridization experiments with tritiated and digoxigenin-labelled HPV18 probes on R-banded chromosomes, we now localize the integrated viral sequences in 12q14-q15. Interestingly, we have previously localized integrated HPV16 sequences in the same chromosomal region in SK-v cells, derived from a pre-invasive vulvar neoplasia. The chromosomal region 12q14-q15 could thus correspond to a preferential site for the integration of HPV DNA in genital tumors. (authors). 29 refs., 2 figs

    Full Text Available Human papillomavirus (HPV infection is the most common sexually transmitted disease worldwide and can result in pre-malignancies or overt malignancies of the skin and mucosal surfaces. HPV-related illnesses are an important personal and public health problem causing physical, mental, sexual and financial detriments. Moreover, this set of malignancies severely affects the immunosuppressed population, particularly HIV-positive patients and organ-transplant recipients. There is growing incidence of HPV-associated anogenital malignancies as well as a decrease in the average age of affected patients, likely related to the rising number of high-risk individuals. Squamous cell carcinoma is the most common type of HPV-related malignancy. Current treatment options for HPV infection and subsequent disease manifestations include imiquimod, retinoids, intralesional bleomycin, and cidofovir; however, primary prevention with HPV vaccination remains the most effective strategy. This review will discuss anogenital lesions in immunocompromised patients, cutaneous warts at nongenital sites, the association of HPV with skin cancer in immunocompromised patients, warts and carcinomas in organ-transplant patients, HIV-positive patients with HPV infections, and the management of cutaneous disease in the immunocompromised patient.

    2007-12-01

    In this editorial we address the controversies surrounding human papillomavirus (HPV) vaccine school-entry mandate legislation, but differentiate between the mandate debate and issues specific to the vaccine itself. Our goal is not to take a stand in favor of or opposed to mandates, but rather to critically examine the issues. We discuss the following arguments against HPV vaccine school-entry requirements: 1. The public health benefit of mandated HPV vaccination is not sufficient to warrant the intrusion on parental autonomy; 2. A vaccine that prevents a non-casually transmitted infection should not be mandated; 3. Opt-out provisions are inherently unfair to parents who oppose HPV vaccination; 4. Limited health care dollars should not be directed toward cervical cancer prevention; and 5. The vaccine is expensive and potential problems with supply suggest that mandates should not be implemented until insurance coverage and supply issues are resolved. Next, we critically evaluate the following critiques of HPV vaccination itself: 1. Giving girls HPV vaccine implies tacit consent to engage in sexual activity; 2. Giving girls this vaccine will confer a false sense of protection from sexually transmitted infections and will lead to sexual disinhibition; 3. Children already have too many vaccinations on the immunization schedule; 4. Long-term side effects of HPV vaccine are unknown; 5. The vaccine's enduring effectiveness is unknown and booster shots may be required; and 6. It is wrong to only target girls with HPV vaccine; boys should be vaccinated as well.

    Genital herpes has a high global prevalence and burden of disease. This manuscript highlights recent advances in our understanding of genital herpes simplex virus (HSV) infections. Studies demonstrate a changing epidemiological landscape with an increasing proportion of genital herpes cases associated with HSV type 1. There is also growing evidence that the majority of infected individuals exhibit frequent, brief shedding episodes that are most often asymptomatic, which likely contribute to high HSV transmission rates. Given this finding as well as readily available serological assays, some have proposed that routine HSV screening be performed; however, this remains controversial and is not currently recommended. Host immune responses, particularly local CD4 and CD8 T cell activity, are crucial for HSV control and clearance following initial infection, during latency and after reactivation. Prior HSV immunity may also afford partial protection against HSV reinfection and disease. Although HSV vaccine trials have been disappointing to date and existing antiviral medications are limited, novel prophylactic and therapeutic modalities are currently in development. Although much remains unknown about genital herpes, improved knowledge of HSV epidemiology, pathogenesis and host immunity may help guide new strategies for disease prevention and control.

    Full Text Available The study set out to investigate what influences the intentions of college students to get vaccinated against genital human papillomavirus (HPV. College men and women were surveyed to understand their intentions. Regression was used and supported that the constructs of the health belief model (HBM as well as gender, norms, and information seeking contributed to predicting intent to receive the HPV vaccine, R2 = .61, F(6, 159 = 39.41, p < .001. Benefits and barriers were the most influential variable, and men were more likely to intend to receive the vaccine. The findings should be applied to future campaigns aimed at increasing preventive health behaviors, especially vaccinations among college students.

  1. Genital reconstruction in exstrophy patients

    Full Text Available Introduction: Surgery for bladder exstrophy has been evolving over the last four to five decades. Because survival has become almost universal, the focus has changed in the exstrophy-epispadias complex to improving quality of life. The most prevalent problem in the long-term function of exstrophy patients is the sexual activity of the adolescent and adult males. The penis in exstrophy patients appears short because of marked congenital deficiency of anterior corporal tissue. Many patients approach for genital reconstruction to improve cosmesis as well as to correct chordee. We report our series of male patients seeking genital reconstruction following exstrophy repair in the past. Materials and Methods: Fourteen adolescent/adult male patients attended urology services during the period January 2000-December 2009 seeking genital reconstruction following exstrophy repair in the past. Results: Three patients underwent epispadias repair, four patients had chordee correction with cosmetic excision of skin tags and seven patients underwent chordee correction with penile lengthening. All patients reported satisfaction in the answered questionnaire. Patients undergoing penile lengthening by partial corporal dissection achieved a mean increase in length of 1.614 ± 0.279 cm dorsally and 1.543 ± 0.230 cm ventrally. The satisfactory rate assessed by the Short Form-36 (SF-36 showed that irrespective of the different genital reconstructive procedures done, the patients were satisfied with cosmetic and functional outcome. Conclusions: Surgical procedures have transformed the management in these patients with bladder exstrophy. Bladders can be safely placed within the pelvis, with most patients achieving urinary continence and cosmetically acceptable external genitalia. Genital reconstruction in the form of correction of chordee, excision of ugly skin tags and lengthening of penis can be performed to give the patients a satisfactory cosmetic and functional

    Human papillomavirus (HPV)-related cancers are a major worldwide public health concern. Virtually all cervical cancer is HPV-related, with 70% caused by HPV16 and -18. Variable proportions of certain non-cervical cancers (e.g., anal, vulvar, oropharyngeal) are HPV-related; over 90% of the HPV-related ones are related to HPV16, -18. The HPV-related cancers are dominated by cervical cancer in the developing world, where cervical cancer screening is limited. In this setting, widespread uptake of...

    Full Text Available OBJECTIVE: To characterize the prevalence and distribution of genital human papillomavirus (HPV types among women in Jamaica, and to explore risk factors associated with HPV infection. METHODS: This was a cross-sectional study that took place in April-July 2010 with 852 sexually-active women, 16-49 years of age, who had attended a selected public or private primary health clinic in one of Jamaica's four health authority regions. Sociodemographic data was collected from each participant by trained study staff. Each participant had a gynecological examination that included a clinical Pap test and a cervical sample for HPV detection and typing-performed using the Research Use Only Linear Array (LA genotyping assay (Roche Diagnostics Corp., Indianapolis, Indiana, United States. Overall and type-specific prevalence of HPV infection was calculated for 37 HPV types included in the LA genotyping assay. RESULTS: HPV DNA was detected in 460 of the 852 women (54.0%. Oncogenic HPV was detected in 297 women (34.9% and HPV types 16/18 were found in 86 women (10.1%. The most frequently occurring HPV types were: 16 (6.2%; 35 (6.0%; 62 and 83 (5.5%; 61 and 58 (5.4%; 84 (4.7%; 18 (4.3%; and, 66 and 81 (4.2%. HPV prevalence was highest among women who were single, young (16-19 years, and had had more than three sexual partners in their lifetime. CONCLUSIONS: These results, coupled with high rates of cervical cancer, support introducing HPV vaccines while maintaining and strengthening cervical cancer screening services. Policy decisionmaking that reflects these results is instrumental to establishing a comprehensive cervical cancer program in Jamaica.OBJETIVO: Determinar la prevalencia y la distribución de los tipos de virus de los papilomas humanos (VPH genitales en las mujeres de Jamaica y explorar los factores de riesgo asociados con la infección por VPH.

    Reported human papillomavirus (HPV) vaccination coverage in England is high, particularly in girls offered routine immunisation at age 12 years. Serological surveillance can be used to validate reported coverage and explore variations within it and changes in serological markers over time. Residual serum specimens collected from females aged 15-19 years in 2010-2011 were tested for anti-HPV16 and HPV18 IgG by ELISA. Based on these results, females were classified as follows: seronegative, probable natural infection, probable vaccine-induced seropositivity, or possible natural infection/possible vaccine-induced seropositivity. The proportion of females with vaccine-induced seropositivity was compared to the reported vaccination coverage. Of 2146 specimens tested, 1380 (64%) were seropositive for both types HPV16 and HPV18 and 159 (7.4%) positive for only one HPV type. The IgG concentrations were far higher for those positive for both HPV types than those positive for only one HPV type. 1320 (62%) females were considered to have probable vaccine-induced seropositivity. Among vaccine-induced seropositives, antibody concentrations declined with increasing age at vaccination and increasing time since vaccination. The proportion of females with vaccine-induced seropositivity was closest to the reported 3-dose coverage in those offered the vaccination at younger ages, with a greater discrepancy in the older females. This suggests either some under-reporting of immunisations of older females and/or that partial vaccination (i.e. one- or two-doses) has provided high antibody responses in 13-17 year olds.

    Full Text Available Female Genital Mutilation is widely practiced in Egypt as well as in big sections of the African continent. The tradition of mutilation of the female genital areas has been practiced over the course of many years in the country and has been attributed to being promoted by the Islamic religion in Egypt. The Islamic religion is the most widely practiced religion within Egypt and therefore is linked to being the main reason why the country possesses one of the highest prevalence rates of the practice within Africa, according to many surveys performed by many leading agencies and nongovernmental organizations that advocate for the abolition of the practice within the country.

    Men who intentionally mutilate or remove their own genitals are likely to be psychotic at the time of the act, to have a number of goals and aims relating to conflicts about the male role, and to be vulnerable to sociocultural and psychological forces in a causal network as yet unknown. However, from a review of the cases of 53 male self-mutilators, it appears that a significant number involve individuals not psychotic at the time of the act but rather having character disorders and rageful feelings toward themselves or women, and transsexual males who premeditate their own gender conversion surgery. The psychiatric consultant's role in the management of such an individual in the general hospital setting includes not only care of a patient with a psychotic or impulse disorder but also involves support of the house staff, who are distressed by the fear, guilt, hopelessness, anger, and revulsion that the patient's act of genital self-mutilation causes.

    It is unknown if human papillomavirus (HPV) serum antibody responses vary by anatomic site of infection. We aimed to assess the seroprevalence for HPV 6, 11, 16 and 18 in association with HPV DNA detection in different anatomic sites among women. This cross sectional population-based study analyzed data from 524 women aged 16-64 years living in the San Juan metropolitan area of Puerto Rico (PR). Questionnaires were used to assess demographic and lifestyle variables, while anogenital and blood samples were collected for HPV analysis. Logistic regression models were used to estimate the adjusted prevalence odds ratio (POR) in order to determine the association between HPV DNA infection status in the cervix and anus and serum antibody status, controlling for different potential confounders. Overall, 46.9% of women had detectable antibodies to one or more types whereas 8.7% had HPV DNA for one or more of these types detected in cervix (4.0%) or anus (6.5%). Women with cervical HPV detection tended to be more HPV seropositive than women without cervical detection (adjusted POR (95%CI): 2.41 (0.90, 6.47), p=0.078); however the type-specific association between cervical DNA and serum antibodies was only significant for HPV 18 (adjusted POR (95% CI): 5.9 (1.03, 33.98)). No significant association was detected between anal HPV and seropositivity (p>0.10). Differences in the anatomic site of infection could influence seroconversion, however, longitudinal studies will be required for further evaluation. This information will be instrumental in advancing knowledge of immune mechanisms involved in anatomic site response.

    High human papillomavirus (HPV) prevalence and low HPV vaccine uptake are significant public health concerns. Disparities in HPV-associated cancers and HPV vaccine uptake rates suggest the need for additional research examining factors associated with vaccine acceptance. This study assessed HPV awareness and knowledge and identified sociodemographic characteristics associated with HPV knowledge at the population level. Data from adult men ( n = 1,197) and women ( n = 1,906) who participated in the National Cancer Institute's 2014 Health Information National Trends Survey were analyzed. Multivariable regression was used to identify predictors of four HPV knowledge categories: (1) general knowledge, (2) cervical cancer knowledge, (3) "other" cancer knowledge (i.e., anal, oral, penile), and (4) vaccine knowledge. Significant gender differences in awareness and knowledge of HPV and the HPV vaccine were revealed. Most participants (>70%) knew that HPV could cause cervical cancer, but fewer (14.9% to 31.5%) knew of the association between HPV and "other" cancers. Women were more likely to report that a health care provider recommended vaccination. Significant predictors of general HPV and HPV vaccine knowledge included gender, education, income, race, and other sociodemographic characteristics. Age and income predicted cervical cancer knowledge. Knowledge of "other" HPV-associated cancers was predicted by having a child under 18 years in the household and relationship status. HPV knowledge appears to be socially patterned. Low HPV knowledge among men and some racial minorities suggests a need for further intervention. Health education should emphasize risks of noncervical HPV-associated cancers. Patient-provider communication that includes education, counseling, and clear recommendations favoring vaccination may improve uptake.

    High risk human papillomavirus (HR-HPV) infection is common and only a small minority of infections become persistent and lead to cervical cancers. Women positive for HR-HPV usually require a second test to avoid unnecessary colposcopies and over treatment. Elevated DNA methylation of HR-HPV L1 and L2 genes in high grade disease has emerged as a promising molecular triage tool. Our aim was to accurately measure methylation levels at selected CpG positions in the HPV18, HPV31 and HPV33 genomes. We focused on the L2, L1, URR and E6 regions because these were previously shown to be interesting areas for study. Pyrosequencing was used to measure methylation in 208 HPV18, 207 HPV31, and 126 HPV33 positive women selected from a London colposcopy referral population. After adjustment for multiple testing, at FDR 5%, elevated methylation was significantly associated with cervical intraepithelial neoplasia grades 2 or worse (CIN2+) in all investigated CpGs in HPV18 L2 and L1. Two of 6 L2 and 12 of 15 L1 sites in HPV31 and 6 of 8 L2 and 3 of 13 L1 sites in HPV33 showed significantly elevated methylation in CIN2+. Methylation of CpG sites in the URR and E6 region of the HPV types was low and most differences were not significant. Elevated methylation of CpG sites in the L1 and L2 regions of HPV18, HPV31 and HPV33 is associated with CIN2+ and a panel test may be useful for triage of women with HR-HPV infections.

    Few studies have included men when assessing differences in knowledge about HPV, and HPV-associated cancers. We examined gender differences in knowledge about HPV, HPV vaccine, and HPV-associated cancers. Multivariable logistic regression models were used to analyze data of 3,677 survey respondents aged 18 years and older from the 2014 Health Information National Trends Survey. Covariates included age, race/ethnicity, marital status, education, income level, regular provider, general health, internet use, and family structure aged 9 to 27 years. Analyses were conducted in 2015. Sixty-four percent of respondents had heard of HPV and the HPV vaccine. Seventy-eight percent of respondents knew HPV causes cervical cancer, but only 29% knew it causes penile cancer, 26% knew it causes anal cancer, and 30% knew it causes oral cancer. In multivariable analyses, males were less likely to have heard of HPV (aOR: 0.33; 95% CI: 0.25-0.45), and less likely to have heard of the HPV vaccine (aOR: 0.24; 95% CI: 0.18-0.32) compared to females. No differences existed between males and females regarding knowledge about HPV-associated cancers. In conclusion, knowledge of HPV, the vaccine, and HPV-associated cancers in both males and females in the United States remains very low, especially among men. Copyright © 2017 Elsevier Inc.

    BACKGROUND Genital warts are caused by human papillomavirus infection and represent one of the most common sexually transmitted diseases. Many infections are transient but the virus may recur, persist, or become latent. To date, there is no effective antiviral treatment to eliminate HPV infection and most therapies are aimed at the destruction of visible lesions. Potassium hydroxide is a strong alkali that has been shown to be safe and effective for the treatment of genital warts and molluscum contagiosum. Cryotherapy is considered one of the most established treatments for genital warts. No comparative trials have been reported to date on the use of potassium hydroxide for genital warts. OBJECTIVE A prospective, open-label, randomized clinical trial was conducted to compare topical potassium hydroxide versus cryotherapy in the treatment of genital warts affecting immunocompetent, sexually active men. METHODS Over a period of 10 months, 48 patients were enrolled. They were randomly divided into two groups and selected on an alternative basis for either potassium hydroxide therapy or cryotherapy. While response to therapy did not differ substantially between both treatment modalities, side effects such as local pain and post-treatment hypopigmentation were considerably more prevalent in the groups treated using cryotherapy. RESULT In our study, potassium hydroxide therapy proved to be at least as effective as cryotherapy and offered the benefit of a better safety profile. CONCLUSION Topical 5% potassium hydroxide presents an effective, safe, and low-cost treatment modality for genital warts in men and should be included in the spectrum of therapies for genital warts.

    Full Text Available This work, besides presenting the characteristics of the so-called genital stage regarding the alterations each one of the components of the drive suffer, examines the idea that the genital stage constitutes the integration —either biological or psychic— of the partial drives. In this sense, it aims to show, based on descriptions done by several thinkers not necessarily psychoanalysts, that the genitality, at least in its male version, turns out to be problematic since it introduces a relation of surprise in the order of the egoic representations of the individual as regards to its own sex organ. By this way, we paradoxically conclude that the genitality is the expression of a partial drive (as opposed to an apparent totality whose source is the penis. // Este trabajo, además de poner de presente las características de la llamada fase genital, en lo tocante a las modificaciones que se suceden en cada uno de los componentes de la pulsión, interroga la idea de que la fase genital constituye la integración acaso biológica, acaso psíquica- de las pulsiones parciales. En este sentido intenta mostrar, tomando como base descripciones hechas por varios pensadores no necesariamente psicoanalistas, que la genitalidad, al menos en su versión masculina, resulta problemática en la medida en que introduce una relación de extrañeza en el orden yoico, del sujeto respecto a su propio órgano sexual. Por esta vía se concluye con la idea paradójica de que la genitalidad es la expresión de una pulsión parcial (en oposición a una aparente totalidad cuya fuente es el pene.

    Full Text Available Introduction. A number of new technologies including cervical cancer screening and vaccination have introduced new tools in the fight against cervical cancer. Methods. This study was set in Odisha, India, at the Acharya Harihar Regional Cancer Center and study research infrastructure at the Asian Institute of Public Health. IRB approvals were obtained and a research assistant recruited 286 women aged 18–49 years, who provided informed consent and completed a survey tool. Data were entered into EpiData software and statistical analysis was conducted. Results. 76.3% women participants were married, 45.5% had sexual debut at age 21 or greater, 60.5% used contraception, 12.2% reported having a Pap smear in the past, and 4.9% reported having prior genital warts. Most, 68.8% had never heard of HPV and 11.9% were aware that HPV is the main cause of cervical cancer. 82.9% women thought that vaccinations prevent disease, and 74.8% said they make the decision to vaccinate their children. Conclusion. The Odisha community demonstrated a low level of knowledge about cervical cancer prevention, accepted vaccinations in the prevention of disease and screening, and identified mothers/guardians as the key family contacts.

    Full Text Available [b]introduction[/b]. Human Papillomavirus (HPV is a group of DNA viruses which is an etiological factor of many benign and malignant diseases of the upper respiratory tract mucosa, female genital tract and the skin. HPV infection is considered a sexually-transmitted infection, but can also be transmitted by non-sexual routes, including perinatal vertical transmission, physical contact, iatrogenic infection and autoinoculation. Recurrent Respiratory Papillomatosis (RRP in children is connected with HPV infection transmitted vertically from mother to child during the passage of the foetus through an infected birth canal. [b]objective. [/b]The aim of this study was to establish the level of Human Papillomaviruses carrier state in upper respiratory tract mucosa in healthy pre-school children, and to identify potential risk factors for HPV infection. [b]materials and method[/b]. After obtaining consent from their parents, 97 pre-school children were examined – 51 girls and 46 boys between the ages of 3 – 5 years; average age – 4 years and 5 months. 68 children were urban dwellers and 29 came from a rural environment. A questionnaire with detailed history was taken including parents’ and child`s personal data, as well as perinatal risk factors in pregnancy. Socio-demographic information was also obtained, including the standard of living, and chosen environmental factors. Routine ENT examination was performed. Exfoliated oral squamous cells were collected from swabs and analysed for the presence of DNA papillomaviruses by polymerase chain reaction. [b]results.[/b] The presence of HPV in the respiratory tract in children was detected in 19.6% cases. ‘High oncogenic potential’ HPVs, such as HPV-16 and HPV-18, were not observed in squamous cell mucosa of the respiratory tract in the children. No significant differences were observed between the HPV carrier state in urban and rural inhabitants.

    Verruca vulgaris (VV) is a prevalent skin condition caused by various subtypes of human papilloma virus (HPV). The most common causes of non-genital lesions are HPV types 2 and 4, and to a lesser extent types 1, 3, 26, 29, and 57. Although numerous therapeutic modalities exist, none is universally effective or without adverse events (AE). Pulsed dye laser (PDL) is a favorable option due to its observed efficacy and relatively low AE rate. However, it is not known which verrucae are most likely to respond to PDL, or whether the causative viral subtype influences this response. The objective of this prospective blinded study was to assess whether the HPV subtype was predictive of response to PDL. For that matter, 26 verrucae from 26 immunocompetent patients were biopsied prior to treatment by PDL. HPV coding sequences were isolated and genotyped using PCR analysis. Patients were treated by PDL (595 nm wavelength, 5 mm spot size, 1.5 ms pulse duration, 12 J/cm 2 fluence) once a month for up to 6 months, and clinical response was assessed. Binary logistic regression analysis and linear logistic regression analysis were used in order to evaluate statistical significance. Different types of HPV were identified in 22 of 26 tissue samples. Response to treatment did not correlate with HPV type, age, or gender. As no association between HPV type and response to PDL therapy could be established, it is therefore equally effective for all HPV types and remains a favorable treatment option for all VV.

    Human papillomavirus (HPV) vaccination and anal cancer screening are valuable, yet underutilized, tools in prevention of HPV-related cancers among sexual and gender minority (SGM) populations. The aim of this study was to characterize primary care providers' (PCPs) practices and perceptions pertaining to HPV vaccination and anal cancer screening. A survey assessing self-reported practice characteristics related to HPV vaccination and anal cancer screening, as well as perceived barriers to vaccination and anal cancer screening at the patient-, provider-, and system-level was distributed to PCPs at a Federally-Qualified Health Center that specializes in care for SGM populations in the greater Boston area. A total of 33 PCPs completed the survey. All PCPs strongly recommended HPV vaccination to their patients by emphasizing that the vaccine is extremely important or very important. Most PCPs told their patients that the HPV vaccine prevents cervical cancer (96.9%), anal cancer (96.9%), oropharyngeal cancer (72.7%), penile cancer (57.5%), and genital warts (63.6%). There is substantial variability among providers regarding recommendations for anal cancer screening and follow-up. Most PCPs perceived that patient-level factors such as poverty, mental illness, and substance use disorders were barriers to HPV vaccination and anal cancer screening. Systems-level barriers such as lack of clinical time with each patient and lack of staffing were also described as barriers to vaccination and screening. Patient-, provider- and systems-level improvements are important to increase HPV vaccination and anal cancer screening rates.

    Full Text Available Aims and Objectives: Certain strains of human papillomavirus (HPV have been shown to be etiologically related to the development of uterine, cervical, and other genital cancers, but their role in the development of malignancies at other sites is less well established. Previous studies have shown HPV in tumors of the head and neck, but its prevalence has varied depending on the detection methods and the types of tumor and/or tissue examined. This study was undertaken for the detection of high-risk HPV types 16 and 18 and human immunodeficiency virus (HIV in oral squamous cell carcinoma. Materials and Methods: Twenty-five patients histologically diagnosed with oral squamous cell carcinoma and 10 apparently normal persons as controls were selected for the present study. Two biopsy specimens were removed surgically by incision biopsy for histopathological examination and polymerized chain reaction (PCR study. Results: Out of 25 oral squamous cell carcinoma subjects, 8 were found to be HPV positive in PCR. Out of these eight subjects, four had HPV 16 and the other four had other genotypes, and one subject was HIV positive. Conclusion: The conclusion drawn from the present study was that well-defined risk factors like HPV may play a prominent role in the development of oral squamous cell carcinomas, in addition to other risk factors. Further studies with a larger sample size are necessary to arrive at conclusions and to explore the relationship of HPV and HIV in oral squamous cell carcinoma.

    The National Human Papillomavirus (HPV) Vaccination Program in Australia commenced in 2007 for females and in 2013 for males, using the quadrivalent HPV vaccine (HPV 6,11,16,18). Thus far, we have demonstrated very substantial reductions in genital warts and in the prevalence of HPV among young Australian women, providing early evidence for the success of this public health initiative. Australia has a long history of school-based vaccination programs for adolescents, with comparatively high coverage. However, it is not clear what factors promote success in a school vaccination program. The HPV.edu study aims to examine: 1) student knowledge about HPV vaccination; 2) psycho-social outcomes and 3) vaccination uptake. HPV.edu is a cluster randomised trial of a complex intervention in schools aiming to recruit 40 schools with year-8 enrolments above 100 students (approximately 4400 students). The schools will be stratified by Government, Catholic, and Independent sectors and geographical location, with up to 20 schools recruited in each of two states, Western Australia (WA) and South Australia (SA), and randomly allocated to intervention or control (usual practice). Intervention schools will receive the complex intervention which includes an adolescent intervention (education and distraction); a decisional support tool for parents and adolescents and logistical strategies (consent form returns strategies, in-school mop-up vaccination and vaccination-day guidelines). Careful process evaluation including an embedded qualitative evaluation will be undertaken to explore in depth possible mechanisms for any observed effect of the intervention on primary and secondary outcomes. This study is the first to evaluate the relative effectiveness of various strategies to promote best practice in school-based vaccination against HPV. The study aims to improve vaccination-related psychosocial outcomes, including adolescent knowledge and attitudes, decision-making involvement, self

    Full Text Available Background Cervical cancer is an important public health concern worldwide, and in both developed and developing countries. In Malaysia, cervical cancer is the second most common cancer in women after breast cancer and colorectal cancer. The relation between cervical cancer and oncogenic human papillomavirus (HPV infection has been well-established and it has been reported that almost all cervical cancers are correlated to oncogenic HPV DNA. Worldwide around 70 per cent of cervical cancer cases are caused by HPV type 16 and HPV type 18 and responsible for 90 per cent of penile and anal cancer in men. However, HPV type 6 and 11 cause over 90 per cent of genital warts in both men and women. Aims The objective was to assess the knowledge and attitude level among health givers and to compare among the groups. Methods This was a cross-sectional multi-centre study. Simple random sampling was adopted to collect the data. A questionnaire has been developed and it was pretested. Medical doctors and nurses of Malaysian health service were the study population. The data was evaluated with the necessary statistical tests as applicable. P-values <0.05 was considered statistically significant. Results Total participants of this study were 629. They mainly doctor and nurses. The average age was 31.68±7.20 years. Regarding HPV vaccination, their mean knowledge and attitude scores (SD were 13.32±2.30 and 9.38±1.45 respectively. Conclusion Medical doctors have statistically significantly higher knowledge and attitude scores than paramedical staff. Knowledge level was statistically significantly correlated with attitude. More in-depth prospection interventional research has been advocated to safeguard the Malaysian population from the atrocities of cervical cancer.

    2017-01-01

    Female genital mutilation (FGM) is illegal in the UK but nevertheless practised in some immigrant communities. Effective educational approaches are required to inform policy and to direct resources, often in the voluntary sector. The opinions in this article arise from discussions with professionals and members of FGM-practising communities. We highlight the importance of sharing experiences and expertise across health and social care professionals as well as working in partnership with culturally sensitive Non-Governmental Organisations. Enlisting the support of men and religious leaders is crucial to breaking down barriers in male-dominated communities and dispelling myths about FGM being a 'requirement' of faith.

    Guerra, B; Puccetti, C; Cervi, F

    2012-10-01

    Genital herpes is a common sexually transmitted infection. In reproductive age it involves the additional risk of vertical transmission to the neonate. Rates of transmission are affected by the viral type and whether the infection around delivery is primary or recurrent. Neonatal herpes is a rare but very severe complication of genital herpes infection and is caused by contact with infected genital secretions at the time of labor. Maternal acquisition of herpes simplex virus (HSV) in the third trimester of pregnancy carries the highest risk of neonatal transmission. Prevention of neonatal herpes depends on preventing acquisition of genital HSV infection during late pregnancy and avoiding exposure of the infant to herpetic lesions during delivery. Uninfected woman should be counselled about the need of avoiding sexual contact during the third trimester. Elective caesarean section before the onset of labor is the choice mode of delivery for women with genital lesions or with prodromal symptoms near the term, even if it offers only a partial protection against neonatal infection. Antiviral suppressive therapy is used from 36 weeks of gestation until delivery in pregnant women with recurrences to prevent genital lesions at the time of labor so reducing the need of caesarean sections. Currently, routine maternal serologic screening is not yet recommended. Because most mothers of infants who acquire neonatal herpes lack histories of clinically evident genital herpes, researchers should focus on the recognition of asymptomatic primary genital HSV infections.

    The aim of this paper is to describe epidemiology and clinical manifestations of oral infection by Human papillomavirus (HPV), with particular attention to potential malignant lesions. A systematic review of the literature was conducted to describe the state of the art about HPV infection in oropharyngeal mucosa and its modalities of transmission, with particular attention to possible simultaneous infection in multiple anatomic sites. The aspects of prevention and control of infection by administering vaccines and the diffusion of sexual education campaigns are discussed also. Therapeutic protocols are also described where necessary. In recent years there has been a growing interest in HPV oral medicine, suggesting a role of such a family of viruses in the development of neoplasms of the oropharyngeal district as well as of the uterine cervix. Even if the mass media have increasingly faced the problem, causing frequent alarming among patients, the dentist therefore needs a complete and up-to-date knowledge of this infectious condition that is one of the most common causes of sexually transmitted mucous membrane infections (e.g. genital, anal and oral). Recent studies about HPV infection are a basic requirement in order to promote the health of patients and provide them with the most exhaustive indications from dentists.

  17. The clinical utility of HPV DNA testing in cervical cancer screening strategies.

    Bhatla, Neerja; Moda, Nidhi

    2009-09-01

    Cervical cancer continues to be the commonest cause of death among women in developing countries, largely due to the failure to the inability to sustain effective cytology-based screening programs. While this burden may come down following implementation of the human papillomavirus (HPV) vaccine, screening will still be required. HPV DNA testing is a promising new technology for cervical cancer prevention and is the most reproducible of all cervical cancer screening tests. Presently, the two assays most widely used for the detection of genital types are the polymerase chain reaction (PCR) and Hybrid Capture 2 assays (hc2). Rapid, affordable tests are expected to be available soon. HPV DNA testing can be used in a variety of clinical scenarios that include primary screening in women older than 30 yr; as an adjunctive test to cytology; in the triage of women with an equivocal cytologic report, e.g., ASC-US; or for follow-up post-treatment for cervical intraepithelial neoplasia (CIN). HPV DNA testing can also be performed on self-collected samples, which allows screening in remote areas and also in women who refuse gynecologic examination.

    2016-01-01

    As one of the most common sexually transmitted diseases, genital herpes is a global medical problem with significant physical and psychological morbidity. Genital herpes is caused by herpes simplex virus type 1 or type 2 and can manifest as primary and/or recurrent infection. This manuscript provides an overview about the fundamental knowledge on the virus, its epidemiology, and infection. Furthermore, the current possibilities of antiviral therapeutic interventions and laboratory diagnosis of genital herpes as well as the present situation and perspectives for the treatment by novel antivirals and prevention of disease by vaccination are presented. Since the medical management of patients with genital herpes simplex virus infection is often unsatisfactory, this review aims at all physicians and health professionals who are involved in the care of patients with genital herpes. The information provided would help to improve the counseling of affected patients and to optimize the diagnosis, treatment, and prevention of this particular disease.

    2017-07-01

    Given the potential significance of mutilation of the external genitalia in medicolegal fatalities, a review of the literature was undertaken to identify subcategories. Such mutilations may have been sustained sometime before death, around the time of death, or after death. The most common type of ante mortem genital mutilations involves cultural practices such as male circumcision. Less common male mutilations such as subincisions are tribally based. Female genital mutilation is found particularly in African, Middle Eastern, or Asian populations. Self-inflicted genital injuries are most common in males and may be related to attempts at suicide, or to self-harming practices. The latter have a strong association with psychiatric illnesses. Postmortem injuries may arise from animal predation or deliberate mutilation of a corpse. The latter may be associated with ante mortem genital injuries in sadistic homicides. The range of possible causes of genital mutilations in forensic cases necessitates extremely careful evaluation. © 2017 American Academy of Forensic Sciences.

    Full Text Available Although cellular immunity is essential for the elimination of human papillomavirus (HPV, the mechanisms involved are still poorly understood. We summarize the main mechanisms involved in cellular immune response to infections caused by HPV. Immunotherapies for HPV-related cancers require the disruption of T-cell response control mechanisms, associated with the stimulation of the Th1 cytokine response.

Discussion The included studies show that both available HPV vaccines are effective in preventing HPV 16 and HPV 18 infections and probable resulting premalignant lesions of the cervix. However, the duration of protection is currently unclear. With regard to side effects, the vaccination can be considered as secure.

A reduction in the incidence and induced mortality through cervical cancer in Germany is not only depending on the vaccine’s clinical efficacy. Effects of the new technology on the overall participation rate in screening programs and the resulting vaccination rate and immunization status are also important factors. The results of identified health economic models vary substantially due to the heterogeneity of methodological approaches as well as chosen input parameters. However, almost all model-based analyses reached the conclusion that the implementation of a vaccination with lifelong protection can be considered as cost-effective, if the present screening practice continues. A comparison of the two vaccines shows, that the cost effectiveness ratios are more favorable with the quadrivalent vaccine than with the bivalent alternative when considering QALY as primary outcome parameter. The reason for this finding might be that in the case of the quadrivalent vaccine the prevention of genital warts can also be incorporated into the analysis. Variations of the duration of protection as well as the discounting rate were identified as the primary influencing factors of cost-effectiveness results.

    The purpose of this study was to investigate the distribution of Chlamydia trachomatis (CT) genotypes in infective diseases of the female lower genital tract, especially in cervical diseases. This study included 128 CT-positive women. DNA was extracted from cervical swabs. Omp1 gene PCR-RFLP and sequencing were used to confirm the subtypes of CT. The association of subtypes with age, clinical symptoms, cervical cytology, and biopsy results was further analyzed. Omp1 gene PCR-RFLP and sequencing showed that the order of prevalent CT genotypes in the female lower genital tract was D (n=38, 29.69%), followed by E (n=28, 21.88%), G (n=21, 16.41%), and F (n=16,12.50%). Genotypes J, H, and K were comparatively rare. Genotype I was not identified in our samples. Further analysis showed that patients with genotype G were more frequently co-infected with other bacteria. Genotype G was also associated with mucopurulent cervicitis (MPC) and cervical intraepithelial neoplasia (CIN). Patients with genotype E were commonly co-infected with HR-HPV. Although genotype D was the most prevalent, it was a relatively low-risk type. These results provide information on distribution of CT genotypes in infective diseases of the female lower genital tract, which is instrumental to developing a vaccine for CT.

    Although genital HPV is the most prevalent STI in the US, rates of vaccination uptake among high-risk subgroups remain low. Investigations of vaccine compliance have mainly targeted mother-daughter dyads, which in some settings may prove difficult. This study examines an innovative culturally tailored, computer-delivered media-based strategy to promote HPV vaccine uptake. Data, inclusive of sociodemographics, sexual behaviors, knowledge, attitudes, and beliefs about HPV and vaccination were collected via ACASI from 216 African American adolescent females (ages 14-18 years) seeking services in family planning and STI public health clinics in metropolitan Atlanta. Data were obtained prior to randomization and participation in an interactive media-based intervention designed to increase HPV vaccination uptake. Medical record abstraction was conducted 7 month post-randomization to assess initial vaccine uptake and compliance. Participants in the intervention were more compliant to vaccination relative to a placebo comparison condition (26 doses vs. Seventeen doses; p=0.12). However, vaccination series initiation and completion were lower than the national average. Thorough evaluation is needed to better understand factors facilitating HPV vaccine uptake and compliance, particularly perceived susceptibility and the influence of the patient-provider encounter in a clinical setting.

  8. High HPV-51 prevalence in invasive cervical cancers: results of a pre-immunization survey in North Sardinia, Italy.

    Directory of Open Access Journals (Sweden)

    Andrea Piana

    Full Text Available BACKGROUND: Human Papilloma virus (HPV is recognized as the etiological agent of benign and malignant ano-genital lesions. The most prevalent genotypes associated with cervical carcinoma are HPV-16 and -18 worldwide. However, recent studies have emphasized the role of other genotypes, such as HPV-51, in the pathogenesis of cervical dysplasia. The aim of the study was to estimate the burden of HPV-51 infection in invasive cervical malignant lesions in Northern Sardinia, Italy. METHODS/PRINCIPAL FINDINGS: An observational, retrospective, prevalence, mono-center study was carried out to evaluate the presence of HPV genotypes in tissues biopsies of cervical lesions (CIN-1, CIN-2, CIN-3 and invasive carcinoma gathered from 1996 to 2009. Biological samples were collected from women admitted consecutively to a tertiary university hospital situated in Sassari, Italy. Molecular methods were used to identify 28 oncogenic HPV types. A total of 155 formalin-fixed and paraffin-embedded cervical tissue samples were analyzed. Approximately half of the cervical lesions were classified as invasive carcinoma. HPV-DNA was detected in 71% of the samples, with a higher frequency (100% in those categorized as invasive neoplasia. Mono- or co-infections were demonstrated in 45.8% and 25.8% of the cervical samples, respectively. Overall, the most prevalent HPV types were -16 (49% and -51 (19.4%, with an increased frequency of detection associated with the severity of the cervical lesions. CONCLUSIONS/SIGNIFICANCE: This survey highlights for the first time the relevant role of HPV-51 infection in the pathogenesis of invasive cervical cancer prior to the introduction of a vaccination program. Although a selection bias could have influenced the results, other recent studies have described the impact of HPV-51. This remarkable epidemiological element should be carefully evaluated, particularly in the view of opting for preventive vaccines, whose cross-protection patterns

    Full Text Available Purpose: Human papillomaviruses (HPV may have a role in some breast cancers. The purpose of this study is to fill important gaps in the evidence. These gaps are: (i confirmation of the presence of high risk for cancer HPVs in breast cancers, (ii evidence of HPV infections in benign breast tissues prior to the development of HPV positive breast cancer in the same patients, (iii evidence that HPVs are biologically active and not harmless passengers in breast cancer.Methods: RNA-seq data from The Cancer Genome Atlas (TCGA was used to identify HPV RNA sequences in breast cancers. We also conducted a retrospective cohort study based on polymerase chain reaction (PCR analyses to identify HPVs in archival specimens from Australian women with benign breast biopsies who later developed breast cancer. To assess whether HPVs in breast cancer were biologically active, the expression of the oncogenic protein HPV E7 was assessed by immunohistochemistry (IHC.Results: Thirty (3.5% low risk and 20 (2.3% high risk HPV types were identified in 855 breast cancers from the TCGA data base. The high risk types were HPV 18 (48%, HPV 113 (24%, HPV 16 (10%, HPV 52 (10%. Data from the PCR cohort study, indicated that HPV type 18 was the most common type identified in breast cancer specimens (55% of 40 breast cancer specimens followed by HPV 16 (13%. The same HPV type was identified in both the benign and subsequent breast cancer in 15 patients. HPV E7 proteins were identified in 72% of benign breast specimens and 59% of invasive breast cancer specimens.Conclusions: There were 4 observations of particular interest: (i confirmation by both NGS and PCR of the presence of high risk HPV gene sequences in breast cancers, (ii a correlation between high risk HPV in benign breast specimens and subsequent HPV positive breast cancer in the same patient, (iii HPVs in breast cancer are likely to be biologically active (as shown by transcription of HPV DNA to RNA plus the expression of

    Human papillomavirus (HPV) vaccines offer primary prevention of cervical cancer and protection against other HPV-associated cancers. HPV vaccine coverage in the United States (U.S.) remains low, particularly among older adolescents/young adults, and the uninsured. We assessed awareness and knowledge of HPV disease, HPV-related cancers, and HPV vaccines among working, uninsured adults. Data from the 2014 Health Information National Trends Survey (HINTS 4, Cycle 4) were used as a benchmark. Patients were surveyed in late 2014 at the Volunteers in Medicine free clinic in Duval County, Florida. Surveys contained validated measures of HPV disease and vaccine knowledge; HPV-related cancer knowledge was also assessed. Two-hundred and ninety-six surveys were analyzable with an 84% participation rate. Half (50.3%) of participants had heard of HPV, and 32.1% had heard of the HPV vaccine; in HINTS, these estimates were 63.6% and 62.7%, respectively (both P HPV disease knowledge was associated with white race and increased education; high vaccine knowledge was associated with white race, increased education, and female sex. Recognition of HPV as a causative agent was 43.9% for cervical, 9.1% for anal, and 11.1% for throat cancers. For all HPV-associated cancers, participants had lower knowledge/recognition relative to HINTS. The uninsured, socioeconomically disadvantaged adults we surveyed were unaware of a ubiquitous virus that can cause cancer and the existence of a vaccine to protect against it. These findings point to settings and populations in which initiatives to promote HPV vaccination as a cancer prevention tool remain critical. © 2016 The Authors.

    To describe knowledge about human papillomavirus (HPV) and HPV vaccination among women ages 19 to 26 seeking a variety of services at reproductive health centers. A secondary objective was to identify common sources of HPV information. Ten reproductive health centers enrolled 365 women ages 19 to 26 in a randomized, controlled trial to determine the effect of automated reminder messages on HPV vaccine completion. Using responses from a 61-item self-administered baseline questionnaire completed before initiating the HPV vaccine, this subanalysis assessed participants' knowledge regarding HPV and the HPV vaccine. Knowledge of HPV prevention, transmission, and disease outcomes among the study population was highly variable. The mean HPV knowledge score was 11.0 of a possible 19 (SD = 3.8). Most participants (77%) had heard of the HPV vaccine before completing the questionnaire and indicated that their primary sources of information about the vaccine were television ads (61%), health care providers (52%), and friends (45%). Despite a relatively high awareness of the vaccine, specific knowledge regarding HPV and the HPV vaccine varied substantially and participant scores highlighted knowledge gaps among vaccine-eligible young women. Media, health care providers, and friends were identified by participants as sources of information and may influence their knowledge of HPV and the HPV vaccine.

    To determine the prevalence and distribution of female genital mutilation (FGM) procedures in a Nigerian population. Five hundred consecutive women were evaluated for evidence of FGM. The WHO classification system was utilized. Demographic and sociocultural information was collected. Thirty-four percent of women were found to have some type of FGM. Type I and Type II procedures were the most common. Fifty-five percent of women were unaware they had FGM and 62% with FGM did not know the reason. Twenty-one percent of women said they were going to have FGM on their daughters. FGM is still broadly practiced among ethnic and religious groups in Nigeria. Educational efforts need to be directed at eliminating this practice.

    Clinicians are faced with increasing requests for female cosmetic genital surgery and prominent amongst these is labiaplasty. The implications of labiaplasty in adolescence are explored with emphasis on what is known about normal genital appearances, pubertal development, anatomy and physiology and the options for surgical intervention including risks and implications. Faced with what is known to date on female cosmetic genital surgery then such interventions should be avoided in adolescence in the absence of defined medical indications until at least the age of 18 years.

    Chlamydia and genital human papillomavirus (HPV) are the two most common sexually transmitted infections (STIs) among teens and young adults in industrialised countries. The majority of adolescents, however, have limited or no knowledge of these infections. Within the context of a cross-sectional survey on awareness and knowledge of sexually transmitted infections, secondary school students attending the 8th grade and above in Bremen and Bremerhaven, two cities in northern Germany, were asked to rate the risk of peers to get infected with HIV, HPV or chlamydia. Between October and December 2011, students aged 12-20 years completed an anonymous, self-administered questionnaire at their school. In addition to answering questions on awareness and knowledge of sexually transmitted infections, all students were also asked to rate the risk of peers to get infected with HIV, HPV or chlamydia. Furthermore, those reporting ever having sexual intercourse were asked to rate their own risk of getting infected with each of the three infections. 1,148 students, 55% female, completed the questionnaire. 27% of the students reported having had sexual intercourse. 68% of all students rated the risk of same-aged students to get infected with HIV/AIDS as high/medium. The corresponding proportions for HPV and chlamydia were 19 and 25% respectively. Those reporting ever having sexual intercourse generally perceived their own risk of getting infected with HIV, chlamydia or HPV as lower than that of their peers. Generally, the risk of getting infected with HIV was perceived as being higher than that of getting infected with HPV or chlamydia, most likely due to the fact that the students were more aware of HIV than of the other two infections. Efforts should be made to improve awareness and knowledge of HPV and chlamydia among school going adolescents, and to make them realize that these are common infections that are preventable.

    Human papillomavirus (HPV) testing using molecular methods in liquid based cytology (LBC) specimens may be useful as an adjunct to cervical screening by cytology. We compared the positivity rate of the commercially available HPV DNA method hybrid capture 2 (hc2) and the commercially available E6\\/E7 mRNA method PreTect HPV-Proofer in cytological specimens (n=299). LBC specimens collected (n=299) represented the following cervical cytological disease categories: Normal (n=60), borderline nuclear abnormalities (BNA) (n=34), CIN1 (n=121), CIN2 (n=60), CIN3 (n=24). Overall, 69% (205\\/299) of the cases were positive by hc2 and 38% (112\\/299) of the cases were positive by PreTect HPV-Proofer. Concordance rates between the two tests were highest in the high-grade cytology cases (CIN2: 67% and CIN3: 83%) and the normal cytology cases (88%) and lowest in the BNA and CIN1 categories (56% and 52%). HPV DNA viral load analyses were carried out on HPV16 (n=55), HPV18 (n=9) and HPV33 (n=13) samples that were positive by PreTect HPV-Proofer. The sensitivity and specificity of PreTect HPV-Proofer and the hc2 DNA test for the detection of high-grade cytology (i.e. CIN2+) were 71.4% and 75.8% vs 100% and 43.7%, respectively. The relatively low detection rate observed by PreTect HPV-Proofer in the whole range of cytological positive cases, combined with a relatively higher specificity and PPV, suggests that PreTect HPV-Proofer may be more useful than hc2 for triage and in predicting high-grade disease.

    1996-06-01

    By modifying the body in meaningful ways, human beings establish their identity and social status. Lip plugs, ear plugs, penis sheaths, cosmetics, ornaments, scarification, body piercings, and genital modifications encode and transmit messages about age, sex, social status, health, and attractiveness from one individual to another. Through sociocultural sexual selection, male genital modification plays an important role as a sociosexual signal in both male competition and female mate choice. The reliability of the signal correlates with the cost of acquiring the trait. Women use a variety of cues to assess male quality. Male genital modification is one way that some women assess their mates. Extreme male genital modifications not only honestly advertise status, sexual potency, and ability to provide sexual satisfaction, they may provide a reliable index of male-female cooperation through the male's commitment to endure pain and risk.

    Denmark is one of the countries where Human papillomavirus (HPV)-vaccination at present includes only girls. However, the burden of HPV-related cancer in men is increasing, which would argue for gender-neutral vaccination. The aim of this study was to examine the burden of HPV-caused cancers in women and men, and to evaluate the potential of HPV-vaccination in cancer control. Data were retrieved from the literature on population prevalence of high risk (HR) HPV, on HR HPV-prevalence and genotypes in HPV-related cancers, and on number of cytology samples in cervical screening. Data on annual biopsies and conisations were retrieved from the Danish National Health Service Register and the Danish National Patient Register. Incidences of HPV-related cancers in Denmark were extracted from NORDCAN. Number of HPV-caused cancers was calculated from number of HPV-related cancers and the proportion known to be caused by high-risk (HR) HPV. In cross-sectional surveys in Denmark, one fifth of women and almost one third of men were found to be positive for HR HPV. Per year, 548 HPV-caused cancer cases were diagnosed in women and 234 in men, and twice as many cancers in women as in men were preventable with HPV vaccination. However, including screening prevented cervical cancers, the burden of cancers caused by HPV-infection would be 1300-2000 in women as compared to 234 in men. Taking screening prevented cervical cancers into account, the cancer control potential of HPV-vaccination is considerably higher in women than in men. HPV-vaccination could reduce the burden of screening on women and on health care resources. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Human Papillomavirus (HPV) 16 E6 serum antibodies are common in people with HPV-related oropharyngeal cancers (HPV-OPC), but not the general population. We explored HPV16 seroprevalence in people with and without oral HPV16 infection, the cause of HPV-OPC. Oral rinse samples were collected semiannually and tested for 36 types of HPV DNA by PCR. HPV16 E6 serum antibodies were tested at the visit of first oral HPV detection in participants with prevalent (n=54), or incident (n=39) oral HPV16 DNA; or at baseline in matched participants with no oral HPV16 DNA (n=155) using multiplex serology assay. Predictors of seropositivity were examined using logistic regression. HPV16 E6 seropositivity (7.5% vs 0.7%; p=0.005) but not seropositivity to the other HPV16 antigens, was significantly more common in those with than without oral HPV16 infection. There were only 8 HPV16 E6 seropositive participants, but oral HPV16 DNA remained a strong predictor of E6 seropositivity after adjustment for other risk factors (aOR=14.6 95%CI, 1.7-122.5). Seroprevalence was similar in those with prevalent (7.4%; 4/54), and incident (7.7%; 3/39) oral HPV16 infection (p=1.00). E6 seroprevalence was associated with reduced oral HPV16 clearance, but was not statistically significant (HR=0.65 95% CI, 0.16-2.70). Seropositive participants were primarily male (87.5%), HIV-positive (75.0%; median CD4 cell-count of 840) and had oral HPV16 DNA (87.5%). History of an HPV-related cancer (0/8) or HPV-related anogenital dysplasia (1/8) was rare, and 4 participants had recent screening showing no anogenital dysplasia. HPV16 E6 seropositivity was higher among people with than without oral HPV16 infection, despite no known anogenital disease in these participants. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Of the ~60 human papillomavirus (HPV) genotypes that infect the cervicovaginal epithelium, only 12-13 "high-risk" types are well-established as causing cervical cancer, with HPV16 accounting for over half of all cases worldwide. While HPV16 is the most important carcinogenic type, variants of HPV16 can differ in their carcinogenicity by 10-fold or more in epidemiologic studies. Strong genotype-phenotype associations embedded in the small 8-kb HPV16 genome motivate molecular studies to understand the underlying molecular mechanisms. Understanding the mechanisms of HPV genomic findings is complicated by the linkage of HPV genome variants. A panel of experts in various disciplines gathered on 21 November 2016 to discuss the interdisciplinary science of HPV oncogenesis. Here, we summarize the discussion of the complexity of the viral-host interaction and highlight important next steps for selected applied basic laboratory studies guided by epidemiological genomic findings.

    Previous Costa Rica Vaccine Trial (CVT) reports separately demonstrated vaccine efficacy against HPV16 and HPV18 (HPV16/18) infections at the cervical, anal, and oral regions; however, the combined overall multisite efficacy (protection at all three sites) and vaccine efficacy among women infected with HPV16 or HPV18 prior to vaccination are less known. Women age 18 to 25 years from the CVT were randomly assigned to the HPV16/18 vaccine (Cervarix) or a hepatitis A vaccine. Cervical, oral, and anal specimens were collected at the four-year follow-up visit from 4186 women. Multisite and single-site vaccine efficacies (VEs) and 95% confidence intervals (CIs) were computed for one-time detection of point prevalent HPV16/18 in the cervical, anal, and oral regions four years after vaccination. All statistical tests were two-sided. The multisite woman-level vaccine efficacy was highest among "naïve" women (HPV16/18 seronegative and cervical HPV high-risk DNA negative at vaccination) (vaccine efficacy = 83.5%, 95% CI = 72.1% to 90.8%). Multisite woman-level vaccine efficacy was also demonstrated among women with evidence of a pre-enrollment HPV16 or HPV18 infection (seropositive for HPV16 and/or HPV18 but cervical HPV16/18 DNA negative at vaccination) (vaccine efficacy = 57.8%, 95% CI = 34.4% to 73.4%), but not in those with cervical HPV16 and/or HPV18 DNA at vaccination (anal/oral HPV16/18 VE = 25.3%, 95% CI = -40.4% to 61.1%). Concordant HPV16/18 infections at two or three sites were also less common in HPV16/18-infected women in the HPV vaccine vs control arm (7.4% vs 30.4%, P HPV16/18 infections at one or more anatomic sites among some women infected with these types prior to HPV16/18 vaccination.

    Seroepidemiology of human papillomaviruses (HPV) among men is poorly understood. We examined the association between seropositivity to cutaneous HPV and 9-valent HPV (9vHPV) types. Six hundred men were randomly selected from the HPV Infection in Men (HIM) Study. Archived serum specimens were tested for antibodies against 9vHPV types [low-risk (6/11) and high-risk (16/18/31/33/45/52/58)], and 14 cutaneous types, including β-types 5/8/12/14/17/22/23/24/38/47, α-type-27, γ-type-4, µ-type-1, and ν-type-41, using a GST L1-based multiplex serology assay. Risk factor data were collected through questionnaires. Logistic regression was used to evaluate associations between mucosal and cutaneous HPV types. Approximately 21% of men were positive for ≥ 1 cutaneous HPV type, and ≥ 1 nine-valent HPV vaccine type at the same time. Men who were seropositive for any-cutaneous HPV were nearly twice as likely to be seropositive for 9vHPV (adjusted odds ratio (AOR) = 1.97, 95% confidence interval (CI): 1.30-2.99), high-risk (AOR = 1.83; 95% CI: 1.04-3.20), low-risk (AOR = 1.92; 95% CI: 1.16-3.18), and four-valent, 4vHPV, (AOR = 2.01; 95% CI: 1.25-3.21). Type-specific cutaneous HPV seropositivity (types: 8/14/17/23/38/27/4/1) was also positively associated with seropositivity to 9vHPV, high-risk, and low-risk categories. These data indicate that exposure to cutaneous HPV and 9vHPV types is common. Future longitudinal studies are needed to assess the temporality of these associations. Copyright © 2017 The Authors.

    2013-01-01

    Full Text Available Chlamydia trachomatis is the most common cause of curable bacterial sexually transmitted infection (STI worldwide. It manifests primarily as urethritis in males and endocervicitis in females. Untreated chlamydial infection in man can cause epididymitis and proctitis. Though most women with Chlamydia infection are asymptomatic or have minimal symptoms, some develop salpingitis, endometritis, pelvic inflammatory disease (PID, ectopic pregnancy and tubal factor infertility. It is associated with an increased risk for the transmission or acquisition of HIV and is also attributed to be a risk factor for the development of cervical carcinoma. Early diagnosis and treatment of infected individuals is required to prevent the spread of the disease and severe sequelae. Traditionally, tissue culture was considered the gold standard for the diagnosis. However, with the availability of newer diagnostic techniques particularly molecular methods which are not only highly sensitive and specific but are cost-effective also, the diagnosis has became fast and easy. The purpose of this review is to study the various aspects of genital C. trachomatis infection. Also the advances related to the clinical picture, various diagnostic modalities, prevention, treatment, drug resistance and control measures will be dealt with.

    To investigate the clinical and economic impacts of school-based administration of the quadrivalent HPV vaccine. A retrospective health-economic analysis was conducted using data collected in Singapore between 2004 and 2005. A dynamic transmission model was adapted for universal vaccination that provided 80% coverage among students aged 11-12 years. Strategy 1 involved only girls, with a 5-year catch-up vaccination to provide 50% coverage among those aged 13-17 years. Strategy 2 included both girls and boys with no catch-up vaccination. Outcomes included the predicted incidence of HPV-related disease over 100 years. Current coverage was assumed to be 5%. Strategy 1 would reduce cervical intraepithelial neoplasia grade 1 (CIN1) by 63.8%, cervical intraepithelial neoplasia grade 2-3 (CIN2-3) by 62.9%, cervical cancer by 50.9%, and genital warts by 78.0% (female individuals) and 73.6% (male individuals). Strategy 2 would reduce CIN1 by 64.0%, CIN2-3 by 63.1%, cervical cancer by 50.7%, and genital warts by 79.9% (female individuals) and 80.1% (male individuals). The incremental cost-effectiveness ratio was S$12 464 for strategy 1 and $27 837 for Strategy 2. These values decreased to $7477 and $22 574, respectively, if a two-dose regimen was adapted. School-based quadrivalent HPV vaccination offered clinical and economic benefits, and is cost-effective in Singapore. © 2017 International Federation of Gynecology and Obstetrics.

    There has been substantial media coverage of the quadrivalent human papillomavirus (HPV) vaccine since the Food and Drug Administration approved Gardasil (Merck & Co., Inc.) on June 8, 2006. The most vocal complaints maintain that its use will promote promiscuity among teenagers, and condemn proposed mandated use for school entry. Some also question evidence for the vaccine's safety. There have been concerns raised by both providers and patients regarding financial barriers to access. Still others argue that additional populations could benefit who have not been included in current recommendations. Clarification of these issues is essential to advance optimal use of this important new vaccine. There is strong evidence to support HPV vaccine as an effective, safe, and efficient public health measure. School mandates are valuable tools to reduce disparities in availability of immunizations. The time has come to consider universal funding as a means to improve access to all recommended vaccines.

    Estonia has high cervical cancer incidence and low screening coverage. We modelled the impact of population-based bivalent, quadrivalent or nonavalent HPV vaccination alongside cervical cancer screening. A Markov cohort model of the natural history of HPV infection was used to assess the cost-effectiveness of vaccinating a cohort of 12-year-old girls with bivalent, quadrivalent or nonavalent vaccine in two doses in a national, school-based vaccination programme. The model followed the natural progression of HPV infection into subsequent genital warts (GW); premalignant lesions (CIN1-3); cervical, oropharyngeal, vulvar, vaginal and anal cancer. Vaccine coverage was assumed to be 70%. A time horizon of 88years (up to 100years of age) was used to capture all lifetime vaccination costs and benefits. Costs and utilities were discounted using an annual discount rate of 5%. Vaccination of 12-year-old girls alongside screening compared to screening alone had an incremental cost-effectiveness ratio (ICER) of €14,007 (bivalent), €14,067 (quadrivalent) and €11,633 (nonavalent) per quality-adjusted life-year (QALY) in the base-case scenario and ranged between €5367-21,711, €5142-21,800 and €4563-18,142, respectively, in sensitivity analysis. The results were most sensitive to changes in discount rate, vaccination regimen, vaccine prices and cervical cancer screening coverage. Vaccination of 12-year-old girls alongside current cervical cancer screening can be considered a cost-effective intervention in Estonia. Adding HPV vaccination to the national immunisation schedule is expected to prevent a considerable number of HPV infections, genital warts, premalignant lesions, HPV related cancers and deaths. Although in our model ICERs varied slightly depending on the vaccine used, they generally fell within the same range. Cost-effectiveness of HPV vaccination was found to be most dependent on vaccine cost and duration of vaccine immunity, but not on the type of vaccine

    We assessed the public health impact and value of vaccinating boys and men with the quadrivalent HPV vaccine in the United States. We used mathematical population models, accounting for both the direct and indirect protective effects of vaccination. Inputs for the models were obtained from public data sources, published literature, and analyses of clinical trial data. Compared with a program of vaccinating girls and women only, including boys and men 9-26 years of age would further decrease the cumulative mean number of genital wart cases, cervical intraepithelial neoplasia 2/3 cases, cancer cases, and cancer deaths by 5,146,000, 708,000, 116,000, and 40,000, respectively, within 100 years. The mean cost-effectiveness ratio (2008 US $) of this strategy was $25,700 (range: 13,600-48,800) per QALY gained if vaccination protects against all HPV 6/11/16/18-associated diseases, and $69,000 (range: 37,700-152,300)/QALY if it only protects against diseases currently in the vaccine indication. Vaccinating boys and men age 9-26 against all HPV 6/11/16/18-associated diseases provides substantial public health benefits and is cost-effective at commonly cited thresholds.

    Integration of human papillomavirus (HPV) DNA into the host genome can be a driver mutation in cervical carcinoma. Identification of HPV integration at base resolution has been a longstanding technical challenge, largely due to sensitivity masking by HPV in episomes or concatenated forms. The aim was to enhance the understanding of the precise localization of HPV integration sites using an innovative strategy. Using HPV capture technology combined with next generation sequencing, HPV prevalence and the exact integration sites of the HPV DNA in 47 primary cervical cancer samples and 2 cell lines were investigated. A total of 117 unique HPV integration sites were identified, including HPV16 (n = 101), HPV18 (n = 7), and HPV58 (n = 9). We observed that the HPV16 integration sites were broadly located across the whole viral genome. In addition, either single or multiple integration events could occur frequently for HPV16, ranging from 1 to 19 per sample. The viral integration sites were distributed across almost all the chromosomes, except chromosome 22. All the cervical cancer cases harboring more than four HPV16 integration sites showed clinical diagnosis of stage III carcinoma. A significant enrichment of overlapping nucleotides shared between the human genome and HPV genome at integration breakpoints was observed, indicating that it may play an important role in the HPV integration process. The results expand on knowledge from previous findings on HPV16 and HPV18 integration sites and allow a better understanding of the molecular basis of the pathogenesis of cervical carcinoma.

    Among those 9-26 years of age, vaccination can prevent specific types of genital human papillomavirus (HPV), the most common sexually transmitted infection and cause of cervical and other cancers. The objective of this study was to estimate the prevalence of and factors associated with HPV vaccine initiation and completion among females surviving childhood cancer. One-hundred fourteen young adults and 230 mothers with daughters surviving childhood cancer completed surveys querying HPV vaccination history along with medical and sociodemographic factors potentially associated with vaccination outcomes. Vaccination rate differences by age necessitated analysis of outcomes by age group: 9-13 years (preadolescents), 14-17 years (adolescents), and 18-26 years (young adults). Multivariable logistic regression was utilized to identify factors associated with HPV vaccination outcomes. Overall, 34.6% (119/344) of survivors initiated and 20.9% (72/344) completed HPV vaccination. Preadolescents were least likely to have initiated vaccination (P vaccination initiation among young adults only (OR = 0.28; 95%CI, 0.10-0.76, P = 0.012). Physician recommendation (OR = 7.54; 95%CI, 1.19-47.69, P = 0.032; adolescent group) and greater treatment intensity (OR = 5.25; 95%CI, 1.00-27.61, P = 0.050; young adult group) were associated with vaccine completion, whereas being non-White was associated with decreased vaccination completion (OR = 0.17; 95%CI, 0.05-0.66, P = 0.010; adolescent group). A minority of youths surviving childhood cancer have initiated or completed HPV vaccination. Strategies to increase vaccination among survivors are discussed. © 2015 Wiley Periodicals, Inc.

    DNA from two novel HPV genotypes, HPV-150 and HPV-151, isolated from hair follicles of immuno-competent individuals, was fully cloned, sequenced and characterized. The complete genomes of HPV-150 and HPV-151 are 7,436-bp and 7,386-bp in length, respectively. Both contain genes for at least six proteins, namely E6, E7, E1, E2, L2, L1, as well as a non-coding upstream regulatory region located between the L1 and E6 genes: spanning 416-bp in HPV-150 (genomic positions 7,371 to 350) and 322-bp in HPV-151 (genomic positions 7,213 to 148). HPV-150 and HPV-151 are phylogenetically placed within the Betapapillomavirus genus and are most closely related to HPV-96 and HPV-22, respectively. As in other members of this genus, the intergenic E2-L2 region is very short and does not encode for an E5 gene. Both genotypes contain typical zinc binding domains in their E6 and E7 proteins, but HPV-151 lacks the regular pRb-binding core sequence within its E7 protein. In order to assess the tissue predilection and clinical significance of the novel genotypes, quantitative type-specific real-time PCR assays were developed. The 95% detection limits of the HPV-150 and HPV-151 assays were 7.3 copies/reaction (range 5.6 to 11.4) and 3.4 copies/reaction (range 2.5 to 6.0), respectively. Testing of a representative collection of HPV-associated mucosal and cutaneous benign and malignant neoplasms and hair follicles (total of 540 samples) revealed that HPV-150 and HPV-151 are relatively rare genotypes with a cutaneous tropism. Both genotypes were found in sporadic cases of common warts and SCC and BCC of the skin as single or multiple infections usually with low viral loads. HPV-150 can establish persistent infection of hair follicles in immuno-competent individuals. A partial L1 sequence of a putative novel HPV genotype, related to HPV-150, was identified in a squamous cell carcinoma of the skin obtained from a 64-year old immuno-compromised male patient.

    Full Text Available During 1983-86, 225 patients were clinically diagnosed to have genital herpes (GH at our clinic. Of these, 90 men and 55 women were currently married. All the spouses were screened clinically and through standardized techniques for isolation and typing of herpes simplex virus, serological testing and Papanicolaou smear. There were 90 couples in whom at least one spouse had GH and in 38 (42% couples both partners had GH. Clinically, 49% of wives and 75% of husbands of GH patients were diagnosed to have the disease. The spouses of recurrent GH patients had a higher frequency of the disease than spouses of primary GH patients. Among spouses who were clinically asymptomatic, 40% had high serological titres suggestive of GH. Wives generally experienced more severe symptoms, especially pain in the lesions. Majority of lesions in both the partners were vesicles and ulcers. Prodromata were more among recurrent GH patients in both the partners. The frequency of recurrences wasalso similar in spouses. Seventy percent of wives and 40% of husbands could not identify any precipitating factor. Intercourse, physical stress and rich food were cited as possible factors in the remaining. All the wives had acquired the diseases through their husbands who were promiscuous. Fifty percent of husbands had been infected before marriage. Given the fact that asymptomatic carriers exist, it is better to consider all marital partners of GH as infected. Repeated and long-term follow, - up examination, particularly of wives of GH patients is therefore essential as an important socio-preventive aspect of this disease.

  20. HPV testing and vaccination in Europe.

    2014-01-01

    Current cytology-based screening has a moderate sensitivity to detect cervical intraepithelial neoplasia grade 3 (CIN 3) and cervical cancer even in those states providing rigorous quality control of their cervical screening programs. The impact of vaccination against human papillomavirus (HPV) types 16 and 18 as well as the incorporation of HPV testing on the detection of CIN 3 and cancer is discussed. HPV testing used as a triage for atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions, test of cure after treatment, and HPV-based primary screening may improve current cervical screening programs.HPV testing as a triage test for ASCUS seems to offer an improved sensitivity, with a similar specificity as compared to repeat cytology for diagnosing high-grade CIN and has been recommended throughout most EU states. HPV testing as a triage test for low-grade squamous intraepithelial lesions has a low specificity and is not recommended in most member states. HPV test of cure offers an improved sensitivity compared to cytology for women with persistent cervical precancer after treatment. HPV-based cervical cancer screening is more effective than screening with cytology. The effects of HPV-based screening depend on the organization of the program and on adherence to algorithms for screening triage. Otherwise, it is likely that HPV-based screening will increase the referral rate to colposcopy including more women with no detectable cervical lesion. HPV vaccination will require many years to evaluate any beneficial effects on cervical cancer incidence and mortality.

    2013-01-01

    Background Data on the psychosocial burden of human papillomavirus (HPV)-related diseases other than cervical cancer are scarce. The objectives of this study were to measure and compare the psychosocial burden and the impact on health-related quality of life (HRQoL) of HPV-related lower genital tract diseases and genital warts (GW) using several generic and disease-specific instruments. Methods Overall, 842 individuals with normal cervical cytology (n = 241), borderline nuclear abnormalities and/or mild dyskaryosis (n = 23), cervical intraepithelial neoplasia (CIN)1 (n = 84), CIN2/3 (n = 203), vulval intraepithelial neoplasia (VIN)2/3 (n = 43), GW (n = 186) and a history of GW (non-current) (n = 62) were included. The generic European Quality of Life Index Version 5D (EQ-5D) questionnaire was completed by patients with GW and VIN2/3. Sexual functioning was evaluated using the Change in Sexual Functioning Questionnaire (CSFQ). Psychosocial impact was measured in women using the HPV Impact Profile (HIP) questionnaire. HRQoL was assessed using a GW-specific questionnaire, the Cuestionario Especifico en Condilomas Acuminados (CECA) (completed by patients with GW and history of GW). For each instrument, scores were compared between groups using the Student's t-test. In addition, utility loss due to GW and VIN2/3 was evaluated by comparing mean EQ-5D scores weighted by age and sex with the UK general population normal values. Results A significant psychosocial impact was found in women diagnosed with HPV-related genital diseases, particularly in those with GW. The health state of younger adults with GW was significantly impaired compared with UK normal values (mean EQ-5D index score 0.86 vs 0.94, p < 0.001 for 18–24-year-olds; 0.87 vs 0.93, p = 0.030 for 25–34-year-olds). VIN2/3 was found to have a significant negative impact on sexual functioning, and women with VIN2/3 had a highly impaired health state compared with women in the

    A simple, rapid and sensitive colorimetric loop mediated isothermal amplification (LAMP) method was established to detect HPV6 and HPV 16 respectively. The method employed a set of four specially designed primers that recognized six distinct sequences of HPV6-E6 or HPV16-E7 for amplification of nucleic acid under isothermal conditions at 63 degrees C for one hour. The amplification process of LAMP was monitored by the addition of HNB (hydroxy naphthol blue) dye prior to amplification. A positive reaction was indicated by a color change from violet to sky blue and confirmed by real-time turbidimeter and agarose electrophoresis. Thirteen cervical swab samples having single infection with 13 different HPV genotypes were examined to evaluate the specificity. A serial dilution of a cloned plasmid containing HPV-E6 or HPV-E7 gene was examined to evaluate the sensitivity. The results showed that no cross-reaction with other HPV genotypes was observed. The colorimetric LAMP assay could achieve a sensitivity of 1000 copies, 10-20 times lower than that of real-time PCR. The assay was further evaluated with 62 clinical specimens and consistent results were obtained compared with the detection using Kai Pu HPV Genotyping Kit. We concluded that this colorimetric LAMP assay had potential usefulness for the rapid screening of the HPV6 or HPV16 infection in the laboratories and hospitals of provincial and municipal region in China.

    Human papillomavirus (HPV)-related screening technologies and HPV vaccination offer enormous potential for cancer prevention, notably prevention of cervical cancer. The effectiveness of these approaches is, however, suboptimal owing to limited implementation of screening programmes and restricted indications for HPV vaccination. Trials of HPV vaccination in women aged up to 55 years have shown almost 90% protection from cervical precancer caused by HPV16/18 among HPV16/18-DNA-negative women. We propose extending routine vaccination programmes to women of up to 30 years of age (and to the 45-50-year age groups in some settings), paired with at least one HPV-screening test at age 30 years or older. Expanding the indications for HPV vaccination and much greater use of HPV testing in screening programmes has the potential to accelerate the decline in cervical cancer incidence. Such a combined protocol would represent an attractive approach for many health-care systems, in particular, countries in Central and Eastern Europe, Latin America, Asia, and some more-developed parts of Africa. The role of vaccination in women aged >30 years and the optimal number of HPV-screening tests required in vaccinated women remain important research issues. Cost-effectiveness models will help determine the optimal combination of HPV vaccination and screening in public health programmes, and to estimate the effects of such approaches in different populations.

    In 2013, approximately one-third of US adolescent males age 13-17 y had received ≥1 doses of HPV vaccines and only 14% had received ≥3 doses. This study used a nationally representative, online survey to explore experiences and attitudes related to HPV vaccination among parents with adolescent sons. Analyses compared the perspective of parents who do not intend to initiate HPV vaccine for ≥1 adolescent son to that of parents who are likely to initiate or continue HPV vaccination. Of 809 parents of sons age 11-17 years, half were classified as Unlikely to Initiate HPV vaccination and 39% as Likely to Vaccinate. A higher proportion of the Likely to Vaccinate group felt their son's doctor was knowledgeable about HPV vaccine, did a good job explaining its purpose, and spent more time discussing HPV vaccine; in contrast, over half of the Unlikely to Initiate group had never discussed HPV vaccine with their child's doctor. The majority of parents in both groups showed favorable attitudes to adolescent vaccination in general, with lower levels of support for HPV vaccine-specific statements. Physician-parent communication around HPV vaccine for adolescent males should build on positive attitude toward vaccines in general, while addressing parents' HPV vaccine-specific concerns.

    Johnston, Christine; Corey, Lawrence

    2016-01-01

    Herpes simplex virus 2 (HSV-2) is a DNA virus that is efficiently transmitted through intimate genital tract contact and causes persistent infection that cannot be eliminated. HSV-2 may cause frequent, symptomatic self-limited genital ulcers, but in most persons infection is subclinical. However, recent studies have demonstrated that the virus is frequently shed from genital surfaces even in the absence of signs or symptoms of clinical disease and that the virus can be transmitted during these periods of shedding. Furthermore, HSV-2 shedding is detected throughout the genital tract and may be associated with genital tract inflammation, which likely contributes to increased risk of HIV acquisition. This review focuses on HSV diagnostics, as well as what we have learned about the importance of frequent genital HSV shedding for (i) HSV transmission and (ii) genital tract inflammation, as well as (iii) the impact of HSV-2 infection on HIV acquisition and transmission. We conclude with discussion of future areas of research to push the field forward. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    2015-01-01

    SUMMARY Herpes simplex virus 2 (HSV-2) is a DNA virus that is efficiently transmitted through intimate genital tract contact and causes persistent infection that cannot be eliminated. HSV-2 may cause frequent, symptomatic self-limited genital ulcers, but in most persons infection is subclinical. However, recent studies have demonstrated that the virus is frequently shed from genital surfaces even in the absence of signs or symptoms of clinical disease and that the virus can be transmitted during these periods of shedding. Furthermore, HSV-2 shedding is detected throughout the genital tract and may be associated with genital tract inflammation, which likely contributes to increased risk of HIV acquisition. This review focuses on HSV diagnostics, as well as what we have learned about the importance of frequent genital HSV shedding for (i) HSV transmission and (ii) genital tract inflammation, as well as (iii) the impact of HSV-2 infection on HIV acquisition and transmission. We conclude with discussion of future areas of research to push the field forward. PMID:26561565

    Genital herpes is an incurable, chronic disease that affects millions of people worldwide. Not only does genital herpes cause painful, recurrent symptoms, it is also a significant risk factor for the acquisition of other sexually transmitted infections such as HIV-1. Antiviral drugs are used to treat herpes simplex virus (HSV) infection, but they cannot stop viral shedding and transmission. Thus, developing a vaccine that can prevent or clear infection will be crucial in limiting the spread of disease. In this review we outline recent studies that improve our understanding of host responses against HSV infection, discuss past clinical vaccine trials, and highlight new strategies for vaccine design against genital herpes.

    Full Text Available Female genital mutilation (FGM, sometimes referred to as female circumcision or female genital cutting, is a harmful cultural practice without any known health benefit. Its short-term and long-term health risks have led to numerous initiatives toward its eradication at international and local levels, over the last two decades. While major challenges remain and millions of girls and women are still at risk of being subjected to FGM, there is growing evidence that interventions that take into account the social dynamics that perpetuate FGM are yielding positive results toward its reduction. Well-recognized as a human rights violation in international treaties, the elimination of female genital mutilation requires ongoing interventions through cross-sectoral approaches that address attitudinal, cultural and behavioral change.

    Full Text Available Symptomatic primary genital herpes infection is very rare in early childhood. Herpes simplex virus 1 type is the infectious agent in 20-50% percent of primery infections. Sexual abuse should be considered when genital herpes is seen in a person before sexual active age. It is mild and self limiting unless the patient is immune compramised. In this paper we discussed a 17 months old patient with genital herpes and approach to genital herpes in children.

    Studies of the human papillomavirus (HPV) vaccines, Cervarix and Gardasil provide strong evidence for the recommendation that HPV vaccines may minimize the incidence of cervical cancer over time. Both Cervarix and Gardasil provided more than 90% efficacy in preventing cervical intraepithelial neoplasia grade 2+ (CIN 2+) disease caused by HPV 16 and 18 in women 16-26 years who were seronegative and PCR-negative for HPV 16 and 18 at baseline. Cervarix provides more than 75% efficacy in independent cross-protection against persistent HPV 31 and 45, and 47% efficacy against HPV 33; whereas Gardasil offers 50% efficacy only against persistent HPV 31. A reduction in excisional therapies for CIN 2+ is nearly 70% for Cervarix, and 40% for Gardasil. Cervarix efficacy is documented to 6.4 years; Gardasil's to 5 years. Immunologically, Cervarix induces three to nine-fold higher peak-neutralizing antibody titers to HPV 16/18 than Gardasil, has significantly higher cervicovaginal mucus-neutralizing antibody presence than Gardasil, and significantly higher B memory cell response than Gardasil. Safety reports indicate injection site reactions for both Cervarix and Gardasil. Rare serious adverse events have been reported.

    2013-01-01

    A 33-year-old man was referred to our institution with papillary masses at the urethral meatus and difficulty urinating. Genital examination showed two piercings on the frenulum, which were penetrating the external urethra. Endoscopic examination revealed papillary tumours over the entire circumference of the penile urethra and the piercing site. The tumours were resected transurethrally. Microscopic examination revealed condylomata acuminata. Human papillomavirus types 6 and 66 were detected in the lesions. Retrograde urethral viral infection is rare because of the protection provided by the mucosal immune system. Genital piercing may have facilitated spread of the human papillomavirus into the urethra.

    Genital papilloma is caused by human papilloma virus (HPV) infection and recurs frequently. Although T cells are known to play a critical role in the control of HPV infection and papilloma development, the function and phenotype of these cells in the lesion remain to be elucidated. In the present study, we examined the function and phenotype of CD4(+) T cells isolated from the lesions of primary (n = 9) and recurrent (n = 11) genital papillomas. In recurrent papillomas, the frequency of proliferating (Ki-67(+)) CD4(+) T cells was significantly reduced compared with primary papillomas. Cytokine production was evaluated by intracellular cytokine staining in anti-CD3/anti-CD28-stimulated CD4(+) T cells. CD4(+) T cells from recurrent lesions showed impaired production of IL-2, IFN-γ, and TNF-α. Of interest, the frequency of cytokine-producing CD4(+) T cells significantly correlated with the frequency of Ki-67(+)CD4(+) T cells. We also studied expression of programmed death-1 (PD-1), a T-cell exhaustion marker. The frequency of PD-1(+)CD4(+) T cells was significantly increased in recurrent lesions and inversely correlated with the frequency of cytokine-producing CD4(+) T cells. The functional significance of PD-1 expression was determined in blocking assays with anti-PD-L1, which restored cytokine production of CD4(+) T cells from recurrent lesions. Taken together, in recurrent genital papilloma lesions, proliferation, and cytokine production by CD4(+) T cells are impaired and the PD-1/PD-L1 interaction is responsible for the functional impairment of CD4(+) T cells.

    BACKGROUND It is important to understand the knowledge that various groups of a population have about cervical cancer and human papillomavirus (HPV) and their attitudes toward HPV vaccination, as it will ultimately influence their decision-making for or against the acceptability of vaccines and other preventive methods. This study was designed to determine the level of knowledge and awareness about cervical cancer, HPV, and the HPV vaccine among Chinese women in Yunnan province. MATERIAL AND METHODS A survey was conducted in Yunnan province by the Laboratory of Molecular Virology in collaboration with the Yunnan First People's Hospital in Feb 2015. A total of 388 women were recruited and asked to participate in a questionnaire-based interview that collected information related to their awareness and knowledge about: (1) cervical cancer, (2) HPV and HPV vaccine and willingness to have their children receive vaccination, and (3) demographic characteristics. RESULTS A total of 388 HPV-positive women were included; 300/388 (73.3%) were Han, and 88/388 (22.7%) were other ethnicities. Overall, 204/388 (52.6%) of the women were aware of cervical cancer, with a significant difference between Han women and women of other ethnic groups (168/388, 56.0% and 36/88, 40.9%; P=0.015). Overall, 26.5% of the women were aware of the role of HPV in cervical cancer; 29.0% of the Han women and 18.2% of women of other ethnic groups were aware of this role of HPV (P=0.05). The knowledge that HPV infection leads to cervical cancer was higher among Han women (29.0%) compared to women of other ethnicities (18.2%). Knowledge about the HPV vaccine was very low in all ethnic groups, but the Han women were more willing to allow their children to be vaccinated before they become sexually active. A similar difference has also been found in women from various regions. CONCLUSIONS Although level of awareness and knowledge about cervical cancer was moderate, knowledge and awareness of HPV and the HPV

    Full Text Available Purpose: To compare human papillomavirus genotype-specific performance of two genotyping assays, Anyplex II HPV28 (Seegene and EuroArray HPV (EuroImmun, with Linear Array HPV (Roche. Methods: DNA extracted from clinican-collected cervical brush specimens in PreservCyt medium (Hologic, from 403 women undergoing management for detected cytological abnormalities, was tested on the three assays. Genotype-specific agreement were assessed by Cohen's kappa statistic and Fisher's z-test of significance between proportions. Results: Agreement between Linear Array and the other 2 assays was substantial to almost perfect (κ = 0.60 − 1.00 for most genotypes, and was almost perfect (κ = 0.81 – 0.98 for almost all high-risk genotypes. Linear Array overall detected most genotypes more frequently, however this was only statistically significant for HPV51 (EuroArray; p = 0.0497, HPV52 (Anyplex II; p = 0.039 and HPV61 (Anyplex II; p=0.047. EuroArray detected signficantly more HPV26 (p = 0.002 and Anyplex II detected more HPV42 (p = 0.035 than Linear Array. Each assay performed differently for HPV68 detection: EuroArray and LA were in moderate to substantial agreement with Anyplex II (κ = 0.46 and 0.62, respectively, but were in poor disagreement with each other (κ = −0.01.

    Because physicians' practices could be modified to reduce missed opportunities for human papillomavirus (HPV) vaccination, our goal was to: (1) describe self-reported practices regarding recommending the HPV vaccine; (2) estimate the frequency of parental deferral of HPV vaccination; and (3)identify characteristics associated with not discussing it. A national survey among pediatricians and family physicians (FP) was conducted between October 2013 and January 2014. Using multivariable analysis, characteristics associated with not discussing HPV vaccination were examined. Response rates were 82% for pediatricians (364 of 442) and 56% for FP (218 of 387). For 11-12 year-old girls, 60% of pediatricians and 59% of FP strongly recommend HPV vaccine; for boys,52% and 41% ostrongly recommen. More than one-half reported ≥25% of parents deferred HPV vaccination. At the 11-12 year well visit, 84% of pediatricians and 75% of FP frequently/always discuss HPV vaccination. Compared with physicians who frequently/always discuss , those who occasionally/rarely discuss(18%) were more likely to be FP (adjusted odds ratio [aOR]: 2.0 [95% confidence interval (CI): 1.1-3.5), be male (aOR: 1.8 [95% CI: 1.1-3.1]), disagree that parents will accept HPV vaccine if discussed with other vaccines (aOR: 2.3 [95% CI: 1.3-4.2]), report that 25% to 49% (aOR: 2.8 [95% CI: 1.1-6.8]) or ≥50% (aOR: 7.8 [95% CI: 3.4-17.6]) of parents defer, and express concern about waning immunity (aOR: 3.4 [95% CI: 1.8-6.4]). Addressing physicians' perceptions about parental acceptance of HPV vaccine, the possible advantages of discussing HPV vaccination with other recommended vaccines, and concerns about waning immunity could lead to increased vaccination rates.

    To analyse the epidemiological aspects contributing to the transmission of human papillomavirus (HPV) lesions (flat, inverted, and papillomatous condylomas) of the uterine cervix, we recorded the sexual behaviour of 146 women who consecutively attended the department of obstetrics and gynaecology of Kuopio University Central Hospital with a cervical HPV lesion (with or without concomitant cervical intraepithelial neoplasia (CIN]. Similar data were collected from an age matched group of women with no signs of gynaecological infection. The sexual habits of the women infected with HPV differed from those of healthy controls in most aspects studied, including an earlier onset of sexual activity (p less than 0.05), lower number of deliveries (p less than 0.05), less regular use of contraceptive measures (p less than 0.05), and use of the condom instead of intrauterine contraceptive device (IUCD) (p less than 0.0001). They also differed from controls in giving histories of more frequent episodes of: CIN (p less than 0.005), abnormal Pap (Papanicolaou) smears (p less than 0.0001), sexually transmitted disease (STD) (p less than 0.05), and genital warts (p less than 0.001). Furthermore, they had more multiple sexual partnerships (both past and current) than the controls (p less than 0.0001 and 0.005 respectively), they had not established permanent partnerships as often as the controls (p less than 0.001), and they had a higher frequency of casual relationships (p less than 0.0001). In addition, their own and their partners' sexual hygiene was poorer than in the control subjects (p less than 0.05 and 0.001 respectively). The results show the dramatic influence of sexual behaviour on the transmission of cervical HPV lesions, which are known to be intimately associated with CIN in many cases.

  6. The HPV vaccine: framing the arguments FOR and AGAINST mandatory vaccination of all middle school girls.

    Vamos, Cheryl A; McDermott, Robert J; Daley, Ellen M

    2008-06-01

    Human papillomavirus (HPV), the virus responsible for cervical cancer, is the most common viral sexually transmitted infection in the United States. A vaccine was approved in 2006 that is effective in preventing the types of HPV responsible for 70% of cervical cancers and 90% of genital warts. Proposals for routine and mandatory HPV vaccination of girls have become sources of controversy for parents of school-aged youth, legislators, members of the medical community, and the public at large. The purpose of this article was to articulate the arguments used by advocates who either oppose or endorse routine, mandatory administration of the vaccine to school-aged girls, thereby assisting school health personnel in being effective participants in framing the relevant issues. Controversy is grounded in moral, religious, political, economic, and sociocultural arguments including whether concerns that the vaccine increases sexual risk taking, sends mixed messages about abstaining from sexual intercourse, usurps parental authority, and increases the potential for development of new health disparities are offset by the value of administering a cost-effective, age-appropriate public health measure targeting a life-threatening problem. Careful consideration of the medical evidence and public health implications is critical but understanding the context of the debate is no less important to the task of responding to public concerns. School health personnel have a role in the discussion about HPV immunization. Being able to articulate the arguments presented herein can help authorities' responsiveness to parents and community groups as the dialogue about this particular health issue evolves further.

    Approximately 20 million people in the United States have genital human papillomavirus (HPV), a sexually transmitted infection linked to cancer. We examined the news information presented about the HPV vaccine in major U.S. newspapers over the 19 months following its Food and Drug Administration (FDA) approval. To answer the question of how news information is presented in ways that might influence public health, we explored the frequency of cancer prevention and sexually transmitted infection prevention message frames used to describe the HPV vaccine, the extent to which journalists relied on official sources, and the presence of personal examples. A content analysis of 547 newspaper articles revealed that less than half of the articles provided detailed health information. Of the articles that contained a message frame, cancer prevention was most frequently employed. Government/political sources, medical doctors, and the Centers for Disease Control and Prevention (CDC) were the most commonly cited sources. Finally, we found that only 16% of all the articles we sampled featured personal accounts. Together, our findings suggest that U.S. newspaper coverage lacked detailed information about both HPV and the HPV vaccine in spite of federal approval of the vaccine, legal mandates for the vaccine, and a widespread information campaign. Implications for public health are discussed.

    To evaluate knowledge of Bangkok women regarding HPV and self-sampled HPV testing, and their attitudes towards testing. Thai women who had lived in Bangkok for more than 5 years, aged 25-to-65 years old, were invited to join the study. Participating women were asked to a complete self-questionnaire (Thai language), with literate assistance as needed. The questionnaire was divided into 3 parts: (I) demographic data, (II) knowledge and (III) attitudes towards self-sampled HPV testing. Before proceeding to Part III of the questionnaire, a 15-minute educational video of self-sampled HPV testing was presented to all participants. Among 2,810 women who answered the questionnaires, 33.7% reported that they did not know about HPV. The characteristic features of these women were older age (>50 years), lower income (Bangkok women did not know about HPV and self-sampled HPV testing, respectively. Approximately 60% of Bangkok women refused to do the self-sampled HPV testing. Significant negative attitudes were concerns that the testing would be unreliable and a lack of confidence to perform the procedure correctly. Education about HPV and self-sampled HPV testing, ease of the procedure, or the testing models may increase rate of acceptability or positive attitudes.

    We assessed human papillomavirus (HPV) prevalence among HPV-16/18-vaccinated and unvaccinated Finnish male adolescents participating in chlamydia screening 4 years after vaccination with AS04-adjuvanted HPV-16/18 vaccine in 2007-2009. Previously vaccinated (n = 395) or unvaccinated (n = 149) male adolescents were enrolled in 12 municipalities. First-void urine samples were tested for HPV types 6, 11, 16, 18, 31, 33, 35, 45, 51, 52, 56, 58, 59, 66, and 68, and prevalence rates for HPV-16/18, and HPV-11/16/18/31/33/45 were reduced profoundly (0% vs 2.1% [P = .02] and 0.8% vs 5.3 [P = .002], respectively). Overall HPV DNA prevalence was also significantly reduced among HPV-16/18-vaccinated (4.1%) compared with unvaccinated subjects (10.1%) (P = .01). In this post hoc study, a highly significant reduction in HPV prevalence 4 years after vaccination suggests that the bivalent HPV-16/18 vaccine has protective efficacy in men. © The Author 2017.

    The incidence of HPV-related head and neck squamous cell carcinoma (HPV-HNSCC) is increasing. Oral samples are easy and non-invasive to collect, but the diagnostic accuracy of oral HPV detection methods for classifying HPV-positive HNSCC tumors has not been well explored. In a systematic review, we identified eight studies of HNSCC patients meeting our eligibility criteria of having: (1) HPV detection in oral rinse or oral swab samples, (2) tumor HPV or p16 testing, (3) a publication date within the last 10 years (January 2007-May 2017, as laboratory methods change), and (4) at least 15 HNSCC cases. Data were abstracted from each study and a meta-analysis performed to calculate sensitivity and specificity. Eight articles meeting inclusion criteria were identified. Among people diagnosed with HNSCC, oral HPV detection has good specificity (92%, 95% CI = 82-97%) and moderate sensitivity (72%, 95% CI = 45-89%) for HPV-positive HNSCC tumor. Results were similar when restricted to studies with only oropharyngeal cancer cases, with oral rinse samples, or testing for HPV16 DNA (instead of any oncogenic HPV) in the oral samples. Among those who already have HNSCC, oral HPV detection has few false-positives but may miss one-half to one-quarter of HPV-related cases (false-negatives). Given these findings in cancer patients, the utility of oral rinses and swabs as screening tests for HPV-HNSCC among healthy populations is probably limited. Copyright © 2017 Elsevier Ltd.

    Female genital mutilation (FGM) is considered to be against the law and against morality not only in Western countries, although a woman of age and able to consent may sometimes think differently. The procedure may have serious physical and emotional consequences for the girl or woman. Nevertheless there are attempts to justify the procedure with medical and hygienic pseudoarguments, ideology, freedom of religion, cultural identity and social adequacy. Outside the Western world, some people claim that religion and culture alone justify the practice. In Germany, parents can lose the right to determine the residence of their daughter, if she is faced with the risk of genital mutilation in order to prevent that the child or girl is taken to her home country. Genital mutilation as a gender-specific threat is recognized as a reason to grant asylum or prevent deportation. Proposals to make genital mutilation a separate punishable offence are presently discussed by the legislator.

  2. Genital evolution: why are females still understudied?

    2014-05-01

    Full Text Available The diversity, variability, and apparent rapid evolution of animal genitalia are a vivid focus of research in evolutionary biology, and studies exploring genitalia have dramatically increased over the past decade. These studies, however, exhibit a strong male bias, which has worsened since 2000, despite the fact that this bias has been explicitly pointed out in the past. Early critics argued that previous investigators too often considered only males and their genitalia, while overlooking female genitalia or physiology. Our analysis of the literature shows that overall this male bias has worsened with time. The degree of bias is not consistent between subdisciplines: studies of the lock-and-key hypothesis have been the most male focused, while studies of cryptic female choice usually consider both sexes. The degree of bias also differed across taxonomic groups, but did not associate with the ease of study of male and female genital characteristics. We argue that the persisting male bias in this field cannot solely be explained by anatomical sex differences influencing accessibility. Rather the bias reflects enduring assumptions about the dominant role of males in sex, and invariant female genitalia. New research highlights how rapidly female genital traits can evolve, and how complex coevolutionary dynamics between males and females can shape genital structures. We argue that understanding genital evolution is hampered by an outdated single-sex bias.

    Full Text Available Female genital mutilation has been drawing international attention for the last couple of decades, but this phenomenon is almost unknown in Serbia. In this work we will point to its basic forms and its presence in the world as well as to the variety of consequences, especially those which are the most common causes of death. With this purpose in mind, the work represents the a review of theoretical debates and empirical studies, based on which relevant data may be gathered, related to the previously mentioned subject of the work. Female genital mutilation is a phenomenon mostly in Africa, but due to migrations has become a problem thoughout the whole world. Traditional and cultural norms of strict patriarchal societies along with deeply rooted inequality of genders have contributed to the maintenance of this custom up till today. This custom includes a sequence of different procedures which are used to injure female genitals even though there are no medical reasons for such acts. They are conducted by older women in insanitary conditions and by means such as scissors, razors or glass which bring numerous consequences which can result in death. Females subdued to infibulation are at greater risk of death, although each of the forms of mutilation may have this consequence. Female genital mutilation represents violence against women due to its inevitable physical consequences and its harmful effect on health. Girls and women are subdued to the procedure which in some cases results in death, for the purpose of the community acceptance, most of all the acceptance of the future husband. Namely, women are elligible for marriage only if they are virgins, which is achieved by genital mutilation, according to the opinion of the community in which this tradition is preserved. Beside that, marriage is of high importance for the economic stability of a woman, considering the fact that all the economic power is held by men. Genital mutilation has the purpose

    Attitudes and practices concerning genital hygiene may influence topical microbicide use by men. This study examines knowledge and behaviours related to hygiene, genital hygiene, circumcision and hygiene, and to genital hygiene before and after sex among men in Nairobi, Kenya. We conducted 463 interviews of men recruited by respondent driven sampling techniques and 10 focus group discussions with a subsample of 100 volunteers from this group. Men were asked individual quantitative survey and qualitative group discussion questions about general hygiene behaviours, genital hygiene, and the temporal relation of genital hygiene behaviours to sexual encounters. Bathing once daily was associated with education, income, and inside tap water. Genital washing aside from regular bathing and washing before sex ever were negatively associated with bathroom crowding. Genital hygiene before the most recent sexual encounter was uncommon and negatively associated with HIV risk perception, bathroom crowding, and ethnicity. Men believed genital hygiene before sex would arouse suspicions of infidelity or cool sexual ardour. Genital hygiene after sex was associated with education, religion, and having inside tap water. Genital hygiene after the most recent sexual encounter was associated with age, income, and with men having at least one child. Genital hygiene behaviours were associated with resource access factors and group discussions suggest that they are modulated by interactions in sexual partnerships. Topical microbicides may improve hygiene before and after sex.

    2018-03-22

    Cervical screening with cytology has been the basis for substantial reductions in cervical cancer incidence and mortality in most high-income countries over the last few decades. More recently, there have been two key, parallel developments which have prompted a major re-consideration of cervical screening. The first is the emergence of evidence on the improved sensitivity of human papillomavirus (HPV) DNA testing compared to cytology, and the second is the large-scale deployment of prophylactic vaccination against HPV. A key challenge to be overcome before HPV screening could be introduced into national cervical screening programs was the specificity of an infection, for detection of precancerous lesions. This has been done in three ways: (1) by considering the appropriate age for starting HPV screening (30 years in unvaccinated populations and 25 years in populations with mature vaccination programs and high vaccine uptake) and the appropriate screening interval; (2) via development of clinical HPV tests, which are (by design) not as sensitive to low viral loads; and (3) by introducing effective triaging for HPV-positive women, which further risk-stratifies women before referral for diagnostic evaluation. This review discusses these major developments and describes how the benefits of HPV screening are being optimized in both unvaccinated and vaccinated populations.

    Human Papilloma Virus (HPV) is becoming a menace worldwide, especially to the developing world, due to its involvement in a variety of malignancies, with cervical cancer being the most important and prevalent. There are many HPV types; HPV 16/18 are the most carcinogenic but few others are also characterized as high-risk (HR). They can cause a variety of low- or high-grade cellular abnormalities, most frequently detected in a routine Pap test. Most infections clear within 2 years, however, a minority persists and potentially could progress to cervical cancer. Molecular tests detecting HPV DNA, RNA or proteins are now being available either commercially or in-house developed. DNA detection is nowadays an established tool for diagnosis and monitoring of HPV-related disease, however, there is lack of a reference method and standardization with reference materials. The various available test formats create confusion on which molecular test to choose and what are its limitations. Therefore, the need for lab accreditation and participation in proficiency testing has to be stressed. Novel HPV biomarkers (RNA, protein etc.) are now intensively examined for their inclusion as adjunct tools. Recently, developed prophylactic vaccines for HPV 16/18 have already proven safe and efficient and raise high expectations for the complete eradication of these types in the future.

    Full Text Available El Virus Papiloma Humano tipo 16 (HPV16 es el principal responsable del desarrollo del cáncer de cuello uterino. Además de su significado clínico, el estudio de la variación genética en las regiones E6, L1 y LCR de este virus ha permitido identificar variantes específicas de diferentes áreas geográficas. Este descubrimiento sugiere una antigua propagación del HPV16 y su coevolución con el género humano. En este contexto, las variantes podrían servir como marcador molecular antropológico, aportando nuevos datos al análisis de patrones migratorios humanos. El objetivo del trabajo fue determinar las variantes de HPV16 en las regiones genéticas E6 y L1 que infectan mujeres guaraníes de Misiones. Para ello se analizaron 39 muestras de cepillados cervicales de mujeres guaraníes infectadas con HPV16. Las variantes en E6 y L1 se identificaron por PCR e hibridación en dot blot. Los resultados obtenidos fueron: el 77% de las variantes Europeas, 20% Africanas y 3% Asiático Americanas. La baja prevalencia de variantes Asiático Americanas coincide con lo reportado por Picconi y col, 2002 para mujeres quechuas, y haría suponer una limitada diseminación del HPV16 durante la época prehispánica. El predominio de las variantes Europeas podría ser resultado de la colonización española y la inmigración europea, mientras que el tráfico de esclavos negros explicaría la presencia de variantes Africanas. Por otra parte, la hipótesis de competencia viral tampoco puede ser descartada.

    Human papillomavirus (HPV) vaccination is a major strategy for preventing cervical and other ano-genital cancers. Worldwide HPV vaccination introduction and coverage will be facilitated if a single dose of vaccine is as effective as two or three doses or demonstrates significant protective effect compared to 'no vaccination'. In a multi-centre cluster randomized trial of two vs three doses of quadrivalent HPV vaccination (Gardasil™) in India, suspension of the vaccination due to events unrelated to the study led to per protocol and partial vaccination of unmarried 10-18 year old girls leading to four study groups, two by design and two by default. They were followed up for the primary outcomes of immunogenicity in terms of L1 genotype-specific binding antibody titres, neutralising antibody titres, and antibody avidity for the vaccine-targeted HPV types and HPV infections. Analysis was per actual number of vaccine doses received. This study is registered with ISRCTN, number ISRCTN98283094; and with ClinicalTrials.gov, number NCT00923702. Of the 17,729 vaccinated girls, 4348 (25%) received three doses on days 1, 60, 180 or later, 4979 (28%) received two doses on days 1 and 180 or later, 3452 (19%) received two doses on days 1 and 60, and 4950 (28%) received one dose. One dose recipients demonstrated a robust and sustained immune response against HPV 16 and 18, albeit inferior to that of 3- or 2-doses and the antibody levels were stable over a 4 year period. The frequencies of cumulative incident and persistent HPV 16 and 18 infections up to 7 years of follow-up were similar and uniformly low in all the vaccinated study groups; the frequency of HPV 16 and 18 infections were significantly higher in unvaccinated age-matched control women than among vaccine recipients. The frequency of vaccine non-targeted HPV types was similar in the vaccinated groups but higher in the unvaccinated control women. Our results indicate that a single dose of quadrivalent HPV

    Full Text Available Abstract Background The female lower genital tract is a gateway for pathogens entering the host through the mucous membrane. One of the prevalent human viruses is Torque teno virus (TTV. The major reported routes of TTV transmission are fecal-oral and parenteral. Furthermore, other modes of transmission, e.g. sexual contact, are suggested. To investigate the sexual route of TTV transmission, cervical smears of healthy women and those with cervical lesions were screened for the presence of TTV DNA. Methods TTV DNA was studied in cervical smears of 95 patients with cervical lesions and 55 healthy women. Paired serum samples were available from 55 and 42 women, respectively. All healthy women had normal cytology while 44 patients had histologically confirmed low-grade lesion (LGL and 51 high-grade lesion (HGL. TTV DNA was detected with primers specific for the non-coding region. In 40 paired cervical smears and serum samples, the phylogenetic group of TTV isolates was determined. The presence of HPV DNA in cervical smears was detected by means of PCR with MY09/11 primers. Results The prevalence of TTV DNA in cervical smears of healthy women was 52.7% and was comparable with that in paired serum samples (50%. Symptomatic women had significantly higher prevalence of TTV DNA in cervical smears (74.7% than healthy controls. The TTV DNA prevalence in patient serum samples was 51%. The phylogenetic groups of TTV serum isolates were concordant with those of TTV from cervical smears of the same subjects. In cervical smears, a wider variety of TTV isolates was found. The viral loads in cervical smears were 10 to 1000 times as high as in sera. The HPV-positive study subjects had significantly higher TTV DNA prevalence than HPV negatives. The prevalence of TTV was not associated with disease severity. Conclusion High prevalence of TTV in cervical smears suggests that sexual transmission is another mode of expansion of TTV infection among the population. The

    Provoked vestibulodynia (PVD) is characterized by the presence of vulvar touch and pain hypersensitivity. Pain with vaginal distension, which motivates treatment seeking and perpetuates distress, is frequently reported with PVD. However, the concordance between the perception of vulvar and vaginal sensation (ie, somatic and visceral genital sensations, respectively) remains unstudied in healthy women, as well as in clinical populations such as PVD. To evaluate the static and dynamic (time-varying) properties of somatic and visceral genital sensation, women with PVD (n=14) and age- and contraceptive-matched healthy controls (n=10) rated varying degrees of nonpainful and painful genital stimulation. Somatic (vulvar) mechanical sensitivity to nonpainul and painful degrees of force were compared to visceral (vaginal) sensitivity to nonpainful and painful distension volumes. Results indicated that healthy women showed substantial individual variation in and high discrimination of vulvar and vaginal sensation. In contrast, PVD was associated with vulvar allodynia and hyperalgesia, as well as vaginal allodynia. Modeling of dynamic perception revealed novel properties of abnormal PVD genital sensation, including temporal delays in vulvar touch perception and reduced perceptual thresholds for vaginal distension. The temporal properties and magnitude of PVD distension pain were indistinguishable from vaginal fullness in healthy controls. These results constitute the first empirical comparison of somatic and visceral genital sensation in healthy women. Findings provide novel insights into the sensory abnormalities that characterize PVD, including an experimental demonstration of visceral allodynia. This investigation challenges the prevailing diagnostic assessment of PVD and reconceptualizes PVD as a chronic somatic and visceral pain condition. Copyright © 2013. Published by Elsevier B.V.

    To assess the role of genital tuberculosis as an etiological factor for ectopic pregnancy. A total of eighteen women of ectopic pregnancy with concomitant female genital tuberculosis and a total of one hundred thirty six patients of ectopic pregnancy over a period of three years were enrolled. Mean age of patients with ectopic pregnancy and concomitant female genital tuberculosis was twenty-six and mean parity was 0.7. Most of these patients were in poor socio-economic group. Diagnosis of female genital tuberculosis was made by presence of granuloma in histopathological examination of endometrial aspirate or tubal specimen, positive acid fast bacilli in microscopy or culture, positive polymerase chain reaction in endometrial tissue and positive findings of genital tuberculosis during laparoscopy or laparotomy. Genital tuberculosis was responsible for 13.2% of all cases of ectopic pregnancy in the present study. Genital tuberculosis appears to be an important cause of ectopic pregnancy in India.

    Background: Denmark is one of the countries where Human papillomavirus (HPV)-vaccination at present includes only girls. However, the burden of HPV-related cancer in men is increasing, which would argue for gender-neutral vaccination. The aim of this study was to examine the burden of HPV-caused....... Data on annual biopsies and conisations were retrieved from the Danish National Health Service Register and the Danish National Patient Register. Incidences of HPV-related cancers in Denmark were extracted from NORDCAN. Number of HPV-caused cancers was calculated from number of HPV-related cancers...... and the proportion known to be caused by high-risk (HR) HPV. Results: In cross-sectional surveys in Denmark, one fifth of women and almost one third of men were found to be positive for HR HPV. Per year, 548 HPV-caused cancer cases were diagnosed in women and 234 in men, and twice as many cancers in women as in men...

    The association between human papillomavirus (HPV) infections and cervical cancer has suggested the design of prophylactic and therapeutic vaccines against genital warts. The HPV capsid has made of two L1 and L2 coat proteins that have produced late in viral infections. Regarding to the recent studies, two commercial prophylactic vaccines have based on L1 viral like particles (VLPs) could strongly induce antibody responses, and protect human body from HPV infections. However, the use of these HPV vaccines has hindered due to their high cost and some limitations. Currently, among various vaccination strategies, live vector-based vaccines have attracted a great attention. Herein, a non-pathogenic strain of the protozoan organism known as Leishmania tarentolae has utilized to induce potent humoral immunity in mice model. At first, cloning of HPV16 L1 gene into Leishmania expression vector has performed and confirmed by PCR and digestion with restriction enzymes. The promastigotes of Leishmania tarentolae (L.tar) have transfected with linearized DNA construct by electroporation. Protein expression has analyzed by SDS-PAGE and western blotting. Then, the immunogenicity of leishmania expressing L1 protein (L.tar-L1) has assessed in mice model. Our data has indicated that subcutaneous immunization of mice with the recombinant L.tar-L1 has led to enhance the levels of IgG1 and lgG2a in comparison with control groups. Furthermore, there was no significant increase in antibody levels between two and three times of immunizations. The recombinant live vector was able to induce humoral immunity in mice without need of any adjuvant. However, further studies have required to increase its efficiency.

    Clinical and subclinical genital herpes simplex virus type 2 (HSV-2) reactivations have been associated with increases in human immunodeficiency virus (HIV)-1 genital shedding. Whether HSV-2 shedding contributes to the selection of specific genital HIV-1 variants remains unknown. We evaluated the genetic diversity of genital and blood HIV-1 RNA and DNA in 14 HIV-1/HSV-2-co-infected women, including seven with HSV-2 genital reactivation, and seven without as controls. HIV-1 DNA and HIV-1 RNA env V1-V3 sequences in paired blood and genital samples were compared. The HSV-2 selection pressure on HIV was estimated according to the number of synonymous substitutions (dS), the number of non-synonymous substitutions (dN) and the dS/dN ratio within HIV quasi-species. HIV-1 RNA levels in cervicovaginal secretions were higher in women with HSV-2 replication than in controls (p0.02). Plasma HIV-1 RNA and genital HIV-1 RNA and DNA were genetically compartmentalized. No differences in dS, dN and the dS/dN ratio were observed between the study groups for either genital HIV-1 RNA or plasma HIV-1 RNA. In contrast, dS and dN in genital HIV-1 DNA were significantly higher in patients with HSV-2 genital reactivation (p genital HIV-1 DNA was slightly higher in patients with HSV-2 genital replication, indicating a trend for purifying selection (p 0.056). HSV-2 increased the genetic diversity of genital HIV-1 DNA. These observations confirm molecular interactions between HSV-2 and HIV-1 at the genital tract level.

    Squamous cell carcinoma (SCC) represents the most common genital malignant tumor in horses. Similar to humans, papillomaviruses (PVs) have been proposed as etiological agents and recently Equine papillomavirus type 2 (EcPV2) has been identified in a subset of genital SCCs. The goals of this study were (1) to determine the prevalence of EcPV2 DNA in tissue samples from equine genital SCCs, penile intraepithelial neoplasia (PIN) and penile papillomas, using EcPV2-specific PCR, (2) to examine the prevalence of latent EcPV2 infection in healthy genital mucosa and (3) to determine genetic variability within EcPV2 and to disentangle phylogenetic relationships of EcPV2 among PVs. EcPV2 DNA was detected in all but one penile SCC (15/16), in all PIN lesions (8/8) and penile papillomas (4/4). Additionally, EcPV2 DNA was demonstrated in one of two metastasized lymph nodes, one contact metastasis in the mouth, two vaginal and one anal lesion. In healthy horses, EcPV2 DNA was detected in 10% (4/39) of penile swabs but in none of vulvovaginal swabs (0/20). This study confirms the presence of EcPV2 DNA in equine genital SCCs and shows its involvement in anal lesions, a lymph node and contact metastases. Latent EcPV2 presence was also shown in normal male genital mucosa. We found that different EcPV2 variants cocirculate among horses and that EcPV2 is related to the Delta+Zeta PVs and is only a very distant relative of high-risk human PVs causing genital cancer. Thus, similar viral tropism and similar malignant outcome of the infection do not imply close evolutionary relationship. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available HPV vaccines are available to men but there are few studies investigating the acceptability of HPV vaccines among men who have sex with men (MSM, a high risk group. We assessed the intention to take up HPV vaccines among MSM in Hong Kong and the associated factors related to cognitions on HPV and HPV vaccines, basing on the Health Belief Model (n = 542. The acceptability of HPV vaccines was 20% (unconditional on efficacies and price, 29.2% (conditional on efficacies and market price, 51.7% (conditional on efficacies and discounted price and 79.1% (conditional on efficacies and free price. Adjusting for background variables, composite scores of perceived susceptibility, perceived severity, perceived barriers and cue to actions were significantly associated with acceptability of HPV vaccines conditional on specific efficacies and the market price. Acceptability of HPV vaccines was highly price sensitive. Future studies need to use conditional measures. Implementation and translational researches are warranted.

    There is a considerable number of studies on the efficacy HPV (human papillomavirus) vaccination against different cancers but relevant information is scattered in diverse journals. This paper is a review summarizing current knowledge of the potential of HPV vaccination against all HPV related cancers. HPV infection is probably the most frequent sexually transmitted disease. At least 13 HPV genotypes are classified as carcinogenic or probably carcinogenic in respect to cervical cancer. Almost 100% of cervical cancers are linked to HPV infection. HPV 16 and HPV 18 are the most frequently involved genotypes and account together for approximately 70% of cervical cancer in the world. Persistent high risk HPV infection is responsible for a significant proportion of vulvar, vaginal, anal and penile carcinomas. The virus has also been implicated in oncogenesis of head and neck cancers, including oropharyngeal cancers. HPV infection can play an important role in cancerogenesis of lung, esophagus, breast, and colon and rectum. On the contrary, published results indicate that HPV infection is not associated with prostate oncogenesis. Strong predominance of HPV 16 has been reported for all HPV associated cancer sites. Generally, it is estimated that approximately 5.2% of all cancers are associated with oncogenic HPV infection. Currently, there are two vaccines on the market; quadrivalent Silgard® (Gardasil®) and bivalent CervarixTM. Large trials for both vaccines have shown efficacy against HPV related infection and disease. Efficacy has been very high in HPV naive subjects to vaccine related types. While HPV vaccination is currently approved for the prevention of cervical cancer, it also has the potential in the prevention of all HPV associated malignancies. The Czech republic belongs to countries that cover HPV vaccination of girls at the age of 13- 14 years by general health insurance. Overall impact of this vaccination remains to be evaluated.

    2015-01-01

    Increased awareness of human papillomavirus (HPV) as an etiological cause of head and neck squamous cell carcinoma has increased the interest in analysis of distinct oral sub-sites. It is currently under debate, whether HPV plays a role in the development of squamous cell carcinoma of the oral cavity (OSCC). The weakness in most published studies is the lack of performing different HPV detection tests combined with analysis for biological activity of the virus. In addition, different sub-sites of the oral cavity had been combined to a single entity, which retrospectively leads to a highly heterogeneous basis of data. In this review we mainly discuss the unclear role of HPV in OSCC development.

    High-risk human papilloma virus (HPV) infections cause cancers in different organ sites, most commonly cervical and head and neck cancers. While carcinogenesis is initiated by two viral oncoproteins, E6 and E7, increasing evidence shows the importance of specific somatic events in host cells for malignant transformation.

Patient developed severe itching and formication (insect-crawling sensation in the lesions for past 1 week, though careful examination did not reveal any insects. Considering that the disease was causing psychological stress and physical symptoms, radiofrequency excision was planned. However, during the procedure, several maggots appeared from the crypts. The procedure was abandoned and maggots were removed manually. Subsequently external giant warts were removed using radiofrequency device. There was no recurrence of excised warts during 3 month follow-up. To our knowledge, this is the second reported case of maggots in genital warts.

  7. Molecular characterization, tissue tropism, and genetic variability of the novel Mupapillomavirus type HPV204 and phylogenetically related types HPV1 and HPV63.

    Full Text Available HPV204 is the only newly identified Mupapillomavirus (Mu-PV type in more than a decade. To comprehensively characterize HPV204, we performed a detailed molecular analysis of the viral genome and evaluated its clinical relevance in comparison to the other Mu-PVs, HPV1 and HPV63. The 7,227-bp long genome of HPV204 exhibits typical genomic organization of Mu-PVs with eight open reading frames (ORFs (E6, E7, E1, E2, E8, E4, L2, and L1. We developed three type-specific quantitative real-time PCRs and used them to test a representative collection (n = 1,006 of various HPV-associated benign and malignant neoplasms, as well as samples of clinically normal cutaneous, mucosal, and mucocutaneous origins. HPV204, HPV1, and HPV63 were detected in 1.1%, 2.7%, and 1.9% of samples tested, respectively, and were present in skin and mucosa, suggesting dual tissue tropism of all Mu-PVs. To evaluate the etiological role of Mu-PVs in the development of HPV-associated neoplasms, Mu-PV viral loads per single cell were estimated. HPV1 and HPV63 were present in high viral copy numbers in 3/43 and 1/43 cutaneous warts, respectively, and were identified as the most likely causative agents of these warts. HPV204 viral load was extremely low in a single HPV204-positive cutaneous wart (7.4 × 10-7 viral copies/cell. Hence, etiological association between HPV204 and the development of cutaneous warts could not be established. To the best of our knowledge, this is the first study to evaluate the genetic variability of Mu-PVs by sequencing complete LCR genomic regions of HPV204, HPV1, and HPV63. We detected several nucleotide substitutions and deletions within the LCR genomic regions of Mu-PVs and identified two genetic variants of HPV204 and HPV63 and five genetic variants of HPV1.

    For more than 25 years, efforts have been geared towards curtailing the practice of female genital mutilation (FGM) in countries like Nigeria. This study was designed to see if all these efforts have made any impact in reducing the prevalence of FGM appreciably in the south-West of Nigeria. To determine the prevalence of female genital mutilation and profiling the trends of FGM affected patients. A prospective study based on direct observation of the external genitalia by health-care workers . Five hundred and sixty five females less than 15 years of age. The children emergency and gynaecological wards of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria from 1st of January to December 31s 2007. Forty one point nine percent of the patients examined had female genital mutilation, 93.2% of these had the procedure before attaining the age of one year. Type 2 FGM predominated (58.22%). The procedure was performed predominantly (64.6%) by traditional birth attendants. The decision to have the procedure done was influenced in 78% of cases by mothers and grandmothers. In 35.4% of cases, there were immediate and short term complications. Demands of tradition predominated (59.1%) as the most important reason for the practice of female genital mutilation. The practice of FGM appears to be still highly prevalent and resistant to change probably due to deep rooted socio-cultural factors. Strategies such as public education campaigns highlighting its negative impact on health and disregard for human rights should be evolved.

    "Anatomy is destiny": Sigmund Freud viewed human anatomy as a necessary, although not a sufficient, condition for understanding the complexity of human sexual function with a solid biologic basis. The aim of the chapter is to describe women's genital anatomy and physiology, focusing on women's sexual function with a clinically oriented vision. Key points include: embryology, stressing that the "female" is the anatomic "default" program, differentiated into "male" only in the presence of androgens at physiologic levels for the gestational age; sex determination and sex differentiation, describing the interplay between anatomic and endocrine factors; the "clitoral-urethral-vaginal" complex, the most recent anatomy reading of the corpora cavernosa pattern in women; the controversial G spot; the role of the pelvic floor muscles in modulating vaginal receptivity and intercourse feelings, with hyperactivity leading to introital dyspareunia and contributing to provoked vestibulodynia and recurrent postcoital cystitis, whilst lesions during delivery reduce vaginal sensations, genital arousability, and orgasm; innervation, vessels, bones, ligaments; and the physiology of women's sexual response. Attention to physiologic aging focuses on "low-grade inflammation," genital and systemic, with its impact on women sexual function, especially after the menopause, if the woman does not or cannot use hormone replacement therapy. © 2015 Elsevier B.V.

    HPV is a major cancer-causing factor in both sexes in the cervix, vulva, vagina, anus, penis, oropharynx as well as the causal factor in other diseases such as genital warts and recurrent respiratory papillomatis. In the context of the arrival of a nonavalent HPV vaccine (6/11/16/18/31/33/45/52/58), this analysis aims to estimate the public health impact and the incremental cost-effectiveness of a universal (girls and boys) vaccination program with a nonavalent HPV vaccine as compared to the current universal vaccination program with a quadrivalent HPV vaccine (6/11/16/18), in Austria. A dynamic transmission model including a wide range of health and cost outcomes related to cervical, anal, vulvar, vaginal diseases and genital warts was calibrated to Austrian epidemiological data. The clinical impact due to the 5 new types was included for cervical and anal diseases outcomes only. In the base case, a two-dose schedule, lifelong vaccine type-specific protection and a vaccination coverage rate of 60% and 40% for girls and boys respectively for the 9-year old cohorts were assumed. A cost-effectiveness threshold of €30,000/QALY-gained was considered. Universal vaccination with the nonavalent vaccine was shown to reduce the incidence of HPV16/18/31/33/45/52/58 -related cervical cancer by 92%, the related CIN2/3 cases by 96% and anal cancer by 83% and 76% respectively in females and males after 100 years, relative to 75%, 76%, 80% and 74% with the quadrivalent vaccine, respectively. Furthermore, the nonavalent vaccine was projected to prevent an additional 14,893 cases of CIN2/3 and 2544 cases of cervical cancer, over 100 years. Depending on the vaccine price, the strategy was shown to be from cost-saving to cost-effective. The present evaluation showed that vaccinating 60% of girls and 40% of boys aged 9 in Austria with a 9-valent vaccine will substantially reduce the incidence of cervical cancer, CIN and anal cancer compared to the existing strategy.

    In 2008 a human papillomavirus (HPV) vaccination programme for cervical cancer prevention was implemented in the UK. Surveillance of vaccine uptake, impact on prevalence of HPV infection and cervical cancer incidence were identified as key measures to evaluate the intervention. To determine baseline HPV prevalence in unvaccinated women and predict impact of HPV vaccination on high-grade cervical disease (CIN2+). A pseudo-anonymous prospective cohort was sampled on entry to the routine cervical screening programme between March 2009 and November 2010. In total, 13,306 eligible females were identified and high-risk (hrHPV) type specific status determined. Potential impact of prophylactic vaccination on CIN2+ was calculated by applying HPV vaccine clinical trial data to the baseline HPV type-specific data. Of 13,306 samples tested, 3545 (26.6%) were confirmed positive for at least one hrHPV type and 1325 (10%) were positive for low risk HPV. HPV16 was the predominant type detected in cases positive with either single or multiple hrHPV infection(s) (5.2% and 4.7%, respectively). Based on hrHPV type-specific data, Gardasil would have prevented 33.2% HPV16/18 unrelated CIN2+ compared to 47.1% for Cervarix. This difference was not statistically significant. Prior to the introduction of the HPV vaccine, approximately one-quarter of young women were positive for hrHPV and one-tenth positive for HPV16. Post-vaccination, we anticipate a substantial absolute risk reduction in high-grade cervical disease associated with both targeted and non-targeted hrHPV types. There is no significant difference between the two commercially available vaccines in terms of clinical impact. Copyright © 2013 Elsevier B.V. All rights reserved.

  16. Characterization of HPV16 L1 loop domains in the formation of a type-specific, conformational epitope

    Full Text Available Abstract Background Virus-like particles (VLPs formed by the human papillomavirus (HPV L1 capsid protein are currently being tested in clinical trials as prophylactic vaccines against genital warts and cervical cancer. The efficacy of these vaccines is critically dependent upon L1 type-specific conformational epitopes. To investigate the molecular determinants of the HPV16 L1 conformational epitope recognized by monoclonal antibody 16A, we utilized a domain-swapping approach to generate a series of L1 proteins composed of a canine oral papillomavirus (COPV L1 backbone containing different regions of HPV16 L1. Results Gross domain swaps, which did not alter the ability of L1 to assemble into VLPs, demonstrated that the L1 N-terminus encodes at least a component of the 16A antigenic determinant. Finer epitope mapping, using GST-L1 fusion proteins, mapped the 16A epitope to the L1 variable regions I and possibly II within the N-terminus. Conclusions These results suggest that non-contiguous loop regions of L1 display critical components of a type-specific, conformational epitope.

    General and subjective information about those who chose to obtain genital piercings was presented. Particularly, the assumptions made from the literature are refuted by objective and subjective data collected from intimately pierced individuals themselves. Professional nurses must not base practice decisions on assumptions but on the "best evidence with clinical experience, research, (as well as) associated patient values" (Sackett, Strauss, Richardson, Rosenberg, & Haynes, 2001, p. 10). Thus, providing clinically competent care is driven by the latest knowledge and evidence from research and patient sources. Data found here provide further empirical evidence that may help to improve client outcomes by advancing evidence-based nursing practice in relation to people with genital piercings.

    The story of Human Papillomavirus vaccination demands reflection not only for its public health impact on the prophylactic management of HPV disease, but also for its relevant economic and social outcomes. Greater than ever data confirm the efficacy and support the urge for effective vaccination plans for both genders before sexual debut. A review of previous experience in gender-restricted vaccination programs has demonstrated a lower effectiveness. Limiting vaccination to women might increase the psychological burden on women by confirming a perceived inequality between genders; and even if all women were immunized, the HPV chain of transmission would still be maintained through men. The cost-effectiveness of including boys into HPV vaccination programs should be re-assessed in view of the progressive drop of the economic burden of HPV-related diseases in men and women due to universal vaccination. The cost of the remarkable increase in anal and oropharyngeal HPV driven cancers in both sexes has been grossly underestimated or ignored. Steps must be taken by relevant bodies to achieve the target of universal vaccination. The analysis of HPV vaccination's clinical effectiveness vs. economic efficacy are supportive of the economic sustainability of vaccination programs both in women and men. In Europe, these achievements demand urgent attention to the social equity for both genders in healthcare. There is sufficient ethical, scientific, strategic and economic evidence to urge the European Community to develop and implement a coordinated and comprehensive strategy aimed at both genders and geographically balanced, to eradicate cervical cancer and other diseases caused by HPV in Europe. Policymakers must take into consideration effective vaccination programs in the prevention of cancers. Copyright © 2015. Published by Elsevier Ireland Ltd.

    Rat somatosensory cortex contains a large sexually monomorphic genital representation. Genital cortex undergoes an unusual 2-fold expansion during puberty. Here, we investigate genital cortex development and female rat sexual maturation. Ovariectomies and estradiol injections suggested sex hormones cause the pubertal genital cortex expansion but not its maintenance at adult size. Genital cortex expanded by thalamic afferents invading surrounding dysgranular cortex. Genital touch was a dominant factor driving female sexual maturation. Raising female rats in contact with adult males promoted genital cortex expansion, whereas contact to adult females or nontactile (audio-visual-olfactory) male cues did not. Genital touch imposed by human experimenters powerfully advanced female genital cortex development and sexual maturation. Long-term blocking of genital cortex by tetrodotoxin in pubescent females housed with males prevented genital cortex expansion and decelerated vaginal opening. Sex hormones, sexual experience, and neural activity shape genital cortex, which contributes to the puberty promoting effects of sexual touch.

    We investigate the demographic factors associated with human papillomavirus (HPV) vaccine-related awareness and knowledge in an emerging (rather than established) Hispanic/Latino population. We surveyed 119 Spanish-speaking, mostly low-income and immigrant, Hispanic/Latino parents and guardians of adolescents 11 to 17 years old (i.e., eligible to receive the HPV vaccine) about their HPV vaccine-related awareness and knowledge. Data collection took place between August 2013 and October 2013 in Salt Lake City, Utah. Participants had moderately high awareness scores, with more than half the participants reporting having heard of cervical cancer (84.5%), HPV (76.4%), and the HPV vaccine (67.3%). HPV vaccine-related knowledge was low, with fewer than half the participants reporting they knew that most people are infected with HPV (32.7%), that HPV is asymptomatic among women (16.4%), that the HPV vaccine requires more than one dose (33.6%), and that the HPV vaccine is recommended for adolescent girls (47.3%) and boys (35.5%). Combined awareness and knowledge was significantly associated with educational attainment (p = .02) and country of origin (p = .03). Results demonstrate moderate to high HPV vaccine-related awareness and limited HPV vaccine-related knowledge among Hispanic/Latino parents living in Utah. These findings will inform educational interventions to improve the HPV vaccine-related awareness and knowledge in this vulnerable population. © 2016 Society for Public Health Education.

    The role of antibody-mediated immunity in preventing newly acquired oral human papillomavirus (HPV) is not well understood. Among 1618 men participating in the HPV Infection in Men (HIM) Study, we evaluated oral rinses for HPV DNA and baseline sera for HPV-6, -11, -16, and -18 L1 antibodies. Thirty percent of men (486) were seropositive for ≥1 HPV type, and 25 men developed incident oral HPV infection (HPV-6 was detected in 7, HPV-11 in 0, HPV-16 in 17, and HPV-18 in 1). Cox models revealed that men with circulating antibodies to HPV-6, -11, -16, or -18 were not less likely to acquire type-specific oral HPV than men without antibodies (hazard ratio for the risk of acquiring HPV-6, -11, -16, or -18, 1.63; 95% confidence interval, .56-4.76). © The Author 2016.

    Cervical cancer risk is increased among women living with HIV (WLH). Human papillomavirus (HPV) vaccination has been shown to be safe and immunogenic among WLH. We examined HPV vaccine awareness and HPV knowledge among WLH. This cross-sectional study collected data from 145 WLH between March 2011 and April 2012. An interviewer-administered survey assessed HPV vaccine awareness and knowledge. Stata/IC 13 was used to perform chi-square tests and multivariate logistic regression analyses. Our sample was 90 % non-Hispanic black and 64 % earned awareness was ten times higher among WLH who knew HPV caused cervical cancer (OR = 10.17; 95 % CI 3.82-27.06). HPV vaccine awareness is low among WLH. Cancer prevention efforts aimed at raising awareness about the HPV vaccine and increasing knowledge about HPV are necessary first steps in reducing cervical cancer disparities among WLH.

    Female genital mutilation (FGM) is the partial or total removal of the female external genitalia or other deliberate injury to the female genital organs, either for cultural or non-therapeutic reasons. This barbaric act is accompanied by a variety of complications ranging from hemorrhage, fracture, infective complications, gynetresia, with its attendant sexual and obstetric difficulties, and death. A 23-year-old girl, with urinary and genital tract obstruction following female genital mutilation(infibulation) is presented. She was managed by elective defibulation, with a satisfactory outcome. Robust health education strategies are needed for the eradication of FGM.

    Head and neck squamous cell carcinomas (HNSCC) are often divided by their aetiology. Noxae associated collectives are compared with the human papilloma virus (HPV)-associated group, whereas different localisations of oral (OSCC) and oropharyngeal (OPSCC) squamous cell carcinomas are mostly discussed as one single group. Our aim was to show that classification by aetiology is not appropriate for OSCC. HPV DNA was detected by PCR in 7 (3.47%) patients, and we identified 12 (5.94%) positive (+) cases by p16INK4a immunostaining. Only 4 (1.98%) of the p16INK4a+ cases were + for HPV using PCR. Our homogenous collective of OSCC allowed us to compare HPV+ and HPV negative (-) patients without creating bias for tumour localisation, age, gender or tumour stage. After testing OSCC samples for HPV positivity, we compared the results of two commonly used HPV detection methods, p16INK4a immunostaining and HPV DNA-related PCR, on 202 OSCC patients. HPV subtypes were determined with an HPV LCD Array Kit. Clinicopathological features of the patients were analysed, and the disease specific survival rates (DSS) for HPV+ and HPV- patients were obtained. p16INK4a immunostaining is a not a reliable HPV detection method for OSCC. Positive p16INK4a immunostaining did not agree with + results from PCR of HPV DNA. Furthermore, the influence of HPV-related oncogenic transformation in OSCC is overestimated. The significance of HPV infection remains clinically unclear, and its influence on survival rates is not relevant to OSCC cases.

    Secondary prophylaxis of cervical cancer consisting in cytology screening tests, despite its effectiveness, does not achieve the desired results. For several years, primary prophylaxis has been available in the form of protective vaccinations. At present, two vaccine preparations are available on the market, and studies conducted on these preparations confirm their almost 100% effectiveness in the prevention of types of HPV present in the vaccine. Analysis of the programmes of protective vaccinations against HPV carried out during the period 2008-2013 in the Lublin Region. The material used in the study was data obtained from the relevant organs of the territorial self-government concerning programmes of vaccinations against HPV, demographic data pertaining to girls aged 10-18 living in the Lublin Region, as well as data published by the National Institute of Public Health - National Institute of Hygiene (NIZP-PZH). The method applied in the study was analysis of records. During the period 2008-2013, in the Lublin Region a total of 5,496 girls were vaccinated within the health programmes. The mean immunization coverage in Lublin is 50%, and in Radzyń Podlaski 59%. The percentage contribution of vaccinations guaranteed free by the local authorities, with relation to the total number of vaccinations performed in the Lublin Region, was from 60 to 77%. The units of territorial self-government allocated the amount of PLN 5,125,359 for the performance of projects associated with execution of free vaccinations. Among the total number of girls vaccinated against HPV, a considerable percentage were those vaccinated within the prophylactic programmes carried out by the units of territorial self-government.

    In the recent period following the approval of the first vaccine targeted against human papillomavirus, it is imperative that we re-evaluate the past, present, and future of cervical cancer prevention. It is clear that the subject of vaccinating young women against a sexually transmitted infection has incited a candid debate among all groups involved. Therefore, we must make the most appropriate and accurate information available to the public and medical communities. The development of vaccines targeted against oncogenic human papillomavirus (HPV) types has made it possible to eliminate approximately 70% of all invasive cervical cancers in women worldwide. However, knowledge about HPV infection and cervical cancer, as well as the need to vaccinate against oncogenic HPV infection, is still lacking among women and physicians. This deficiency could be a key reason why some parents continue to have reservations about vaccinating their daughters. In order for HPV vaccination programs to be highly successful, multiple barriers must be overcome. Review of lessons learned to date has demonstrated that continued tailored and targeted educational and awareness initiatives are required for healthcare professionals, media, patients, and parents. This article also examines the impact of the HPV vaccination awareness campaign on media and public policy dynamics.

  12. HPV disease transmission protection and control

    Directory of Open Access Journals (Sweden)

    Neil D. Christensen

    2016-09-01

    Full Text Available Human papillomaviruses (HPVs represent a large collection of viral types associated with significant clinical disease of cutaneous and mucosal epithelium. HPV-associated cancers are found in anogenital and oral mucosa, and at various cutaneous sites. Papillomaviruses are highly species and tissue restricted, and these viruses display both mucosotropic, cutaneotropic or dual tropism for epithelial tissues. A subset of HPV types, predominantly mucosal, are also oncogenic and cancers with these HPV types account for more than 200,000 deaths world-wide. Host control of HPV infections requires both innate and adaptive immunity, but the viruses have developed strategies to escape immune detection. Viral proteins can disrupt both innate pathogen-sensing pathways and T-cell based recognition and subsequent destruction of infected tissues. Current treatments to manage HPV infections include mostly ablative strategies in which recurrences are common and only active disease is treated. Although much is known about the papillomavirus life cycle, viral protein functions, and immune responsiveness, we still lack knowledge in a number of key areas of PV biology including tissue tropism, site-specific cancer progression, codon usage profiles, and what are the best strategies to mount an effective immune response to the carcinogenic stages of PV disease. In this review, disease transmission, protection and control are discussed together with questions related to areas in PV biology that will continue to provide productive opportunities of discovery and to further our understanding of this diverse set of human viral pathogens.

    This research examines the influence of evidence type (statistical, narrative, or hybrid) and narrative type (first-person or third-person) on risk perception about human papillomavirus (HPV) and behavioral intention to get the HPV vaccine. In total, 174 college students who had not received the HPV vaccine participated in a controlled experiment. Results show that the hybrid message containing both statistical and narrative descriptions of HPV resulted in greater perceived risk of getting HPV than either of the messages containing just one type of evidence--statistical or narrative. Moreover, the first-person narrative message led to greater risk perception about HPV than the third-person narrative message. Both evidence type and narrative type had an indirect effect on intention to get the HPV vaccine free of cost through HPV risk perception. Implications of the findings for vaccine risk communication are discussed.

    Despite the availability of the human papillomavirus (HPV) vaccine for males, uptake of the vaccine has been low, particularly among young adult males. This study aimed to investigate the levels of HPV vaccination and predictors of HPV vaccine completion in college men ages 18-26. We analyzed data from the 2015 College Student Health Survey, which was administered at 17 post-secondary institutions in Midwest areas. We included only responses from male participants who were ages 18-26 years old, resulting in a sample size of 2516. We used Andersen's Behavioral Model of Health Services Utilization to guide our study design. Multivariate logistic regression was used to examine predictors of HPV vaccine receipt. College-aged males in our sample had a HPV vaccine completion rate of 50.0%. Male students who were younger, had at least one parent who held a graduate degree, had initiated sex, and were enrolled at a private 4-year institution were more likely to have been vaccinated. These findings suggest that HPV vaccination in college-aged men are low. Efforts are needed to increase HPV vaccination in male students who are older, from lower socioeconomic statuses, have not initiated sex, and enrolled at public institutions. Findings also indicate important gender disparities in vaccine uptake that must be addressed in order to achieve optimal vaccine uptake in college-aged males.

    Genital melanoma is a rare pathology. We present the experience of two comprehensive cancer centers in Lyon (France) in the management of genital melanoma in order to identify prognostic factors and optimal treatments. Between April 1992 and Mars 2014, 16 patients with a primary genital melanoma were referred to our department. Nine patients presented a vaginal melanoma, six vulvar melanomas and only one cervical melanoma. The median dimension of the lesion was 33.7 mm (5-100 mm). The AJCC stage ranged from IB to IIIC. 12 cases were the classic dark-blue flat melanoma and the other 4 cases were an atypical amelanotic tumor. Wide local surgery was performed in nine patients. A radical surgery was performed in six patients. In the large cervical melanoma, radiotherapy was performed as first-line treatment. In all the patients regional lymph node staging was performed. Adjuvant treatment was realized in nine patients. Two patients are alive without recurrence. Only one patient was lost to the first follow-up. The other 13 patients experienced a rapid recurrence. The median disease-free survival and the median overall survival were 11.8 months (2-49 m) and of 30.4 m (11-144 m), respectively. The disease-free survival and overall survival could be linked to a clinical presentation (Breslow thickness and morphology of lesion) associated to the early diagnosis. In our small series, the most important prognosis factor remains the tumor thickness. These rare lesions should be treated in experienced centers in order to improve their prognostic.

    Full Text Available Abstract Background High-risk strains of human papillomavirus (HPV cause cervical cancer. American Indian (AI women in the Northern Plains of the U.S. have significantly higher incidence and mortality rates for cervical cancer than White women in the same geographical area. We compared HPV prevalence, patterns of HPV types, and infection with multiple HPV types in AI and White women living in South Dakota, U.S. Methods We analyzed the HPV status of cervical samples collected in 2006-2008 from women aged 18-65 years who attended two rural AI reservation clinics (n = 235 or an urban clinic in the same area serving mostly White women (n = 246. Data collection occurred before HPV vaccination was available to study participants. HPV DNA was amplified by using the L1 consensus primer system and an HPV Linear Array detection assay to identify HPV types. We used chi-square tests to compare HPV variables, with percentages standardized by age and lifetime number of sexual partners. Results Compared to White women, AI women were younger (p = 0.01 and reported more sexual partners (p p p = 0.001. Infections among AI women showed a wider variety and very different pattern of HPV types, including a higher prevalence of mixed HPV infections (19% [95% CI = 26-38] vs. 7% [95% CI = 4-11]; p = 0.001. AI women had a higher percentage of HPV infections that were not preventable by HPV vaccination (32% [95% CI = 26-38] vs. 15% [95% CI = 11-21]; p Conclusions A higher HPV burden and a different HPV genotyping profile may contribute to the high rate of cervical cancer among AI women.

    Full Text Available Seventy five patients of recurrent genital herpes (RGH treated with oral or topical acyclovir and placebo were compared and followed for periods ranging 4 to 8 years in a prospective study. Oral acyclovir definitely helps RGH patients; it shortens healing time; postpones recurrences and instills confidence in the patients. There is sufficient evidence that RGH dies a natural death with time as seen after 8 years follow up in placebo group patients. Topical use of acyclovir cream is not as useful as believed.

    Female genital mutilation (FGM) is a collective term for the deliberate alteration, removal and cutting of the female genitalia. It has no known health benefits and can have negative physical and psychological consequences. The number of women and girls in the UK that are affected by FGM is unknown. Recent NHS data suggested that FGM has been evident (declared or observed) in women who have accessed health care; however, there are gaps in knowledge and a limited evidence base on the health consequences of FGM. This article explores the urological complications experienced by women who have undergone this practice, and the effects this can have on their health and wellbeing.

    2004-10-01

    This review will look critically at recent research articles that pertain to children and adolescents who present with genital injuries. Many recently published articles have noted that the history as given by the child or adolescent is the most important factor in determining the etiology of genital injuries as abuse or accidental. The history is more important than any documented or lack of documented findings on physical examination. Distinguishing whether the injury was accidental or caused by abuse is of significance to the family and the injured child or adolescent. Genital examinations of victims of documented abuse are often normal. Examinations of pregnant adolescents may appear normal, the only evidence that intercourse has taken place being pregnancy. Documented accidental genital injuries are described; unfortunately such injuries can easily be confused with sexual abuse. Photographic documentation of injuries by colposcopic photography has allowed a new level of peer review, improving the understanding of what are normal and non-specific findings, many of which were considered to be abnormal in the past. The psychological impact of living in a violent, war-torn culture, or surviving a traumatic genital injury are reviewed. New ideas on the management of genital trauma are also reported. Increasingly, victims of sexual abuse are found to have normal examinations, and the victim's history becomes the most important determining factor. Peer review has led to a better understanding of the wide variations in the normal genital examination. Psychological support for these victims is important in the management of genital injuries.

    OBJECTIVE In October 2011, the Advisory Committee on Immunization Practices (ACIP) recommended the quadrivalent human papillomavirus vaccine (HPV4) for the routine immunization schedule for 11- to 12-year-old boys. Before October 2011, HPV4 was permissively recommended for boys. We conducted a study in 2010 to provide data that could guide efforts to implement routine HPV4 immunization in boys. Our objectives were to describe primary care physicians’: 1) knowledge and attitudes about human papillomavirus (HPV)-related disease and HPV4, 2) recommendation and administration practices regarding HPV vaccine in boys compared to girls, 3) perceived barriers to HPV4 administration in boys, and 4) personal and practice characteristics associated with recommending HPV4 to boys. METHODS We conducted a mail and Internet survey in a nationally representative sample of pediatricians and family medicine physicians from July 2010 to September 2010. RESULTS The response rate was 72% (609 of 842). Most physicians thought that the routine use of HPV4 in boys was justified. Although it was permissively recommended, 33% recommended HPV4 to 11- to 12-year-old boys and recommended it more strongly to older male adolescents. The most common barriers to HPV4 administration were related to vaccine financing. Physicians who reported recommending HPV4 for 11- to 12-year-old boys were more likely to be from urban locations, perceive that HPV4 is efficacious, perceive that HPV-related disease is severe, and routinely discuss sexual health with 11- to 12-year-olds. CONCLUSIONS Although most physicians support HPV4 for boys, physician education and evidence-based tools are needed to improve implementation of a vaccination program for males in primary care settings.

    Purpose: To investigate the relationship between human papillomavirus (HPV) and Epstein-Barr virus (EBV) in nonendemic nasopharyngeal carcinoma (NPC) and assess the prognostic implications of viral status. Methods and Materials: Paraffin-embedded tumor specimens from 62 patients with primary NPC diagnosed between 1985 and 2011 were analyzed for EBV and high-risk HPV. EBV status was determined by the use of in situ hybridization for EBV encoded RNA. HPV status was assessed with p16 immunohistochemistry and multiplex polymerase chain reaction MassArray for determination of HPV type. Proportional hazards models were used to compare the risk of death among patients as stratified by viral status. Results: Of 61 evaluable tumors, 26 (43%) were EBV-positive/HPV-negative, 18 (30%) were HPV-positive/EBV-negative, and 17 (28%) were EBV/HPV-negative. EBV and HPV infection was mutually exclusive. HPV positivity was significantly correlated with World Health Organization grade 2 tumors, older age, and smoking (all P<.001). The racial distribution of the study population was 74% white, 15% African American, and 11% Asian/Middle Eastern. Among HPV-positive patients, 94% were white. At a median follow-up time of 7 years, HPV-positive and EBV/HPV-negative tumors exhibited worse outcomes than did EBV-positive tumors, including decreased overall survival (hazard ratio [HR] 2.98, P=.01; and HR 3.89, P=.002), progression-free survival (HR 2.55, P=.02; and HR 4.04, P<.001), and locoregional control (HR 4.01, P=.03; and HR 6.87, P=.001). Conclusion: In our Midwestern population, high-risk HPV infection may play an etiologic role in the development of nonendemic, EBV-negative NPC. Compared with EBV-positive NPC, HPV-positive and EBV/HPV-negative NPC are associated with worse outcomes. A larger confirmatory study is needed to validate these findings.

    Commercial molecular tests for human papillomaviruses (HPV) are invaluable diagnostic tools in cervical carcinoma screening and management of women with cervical precancerous lesions as well as important research tools for epidemiological studies, vaccine development, and implementation and monitoring of vaccination programs. In this third inventory of commercial HPV tests, we identified 193 distinct commercial HPV tests and at least 127 test variants available on the market in 2015, which represents a 54% and 79% increase in the number of distinct HPV tests and variants, respectively, in comparison to our last inventory performed in 2012. Identified HPV tests were provisionally divided into eight main groups and several subgroups. Among the 193 commercial HPV tests, all but two target alpha-HPV types only. Although the number of commercial HPV tests with at least one published study in peer-reviewed literature has increased significantly in the last three years, several published performance evaluations are still not in line with agreed-upon standards in the HPV community. Manufacturers should invest greater effort into evaluating their products and publishing validation/evaluation results in peer-reviewed journals. To achieve this, more clinically oriented external quality-control panels and initiatives are required. For evaluating the analytical performance of the entire range of HPV tests currently on the market, more diverse and reliable external quality-control programs based on international standards for all important HPV types are indispensable. The performance of a wider range of HPV tests must be promptly evaluated on a variety of alternative clinical specimens. In addition, more complete HPV assays containing validated sample-extraction protocols and appropriate internal controls are urgently needed. Provision of a broader range of automated systems allowing large-scale HPV testing as well as the development of reliable, rapid, and affordable molecular

    The incidence of human papillomavirus (HPV) positive oral squamous cell carcinoma (OSCC) continues to increase over time, challenging healthcare providers to address their patients' HPV-related concerns. This prospective study assessed health literacy, HPV knowledge, utilization and trust in information sources among patients with incident HPV-positive or HPV-negative OSCC diagnosed at the Ohio State University from 2011 to 2015. Health literacy was assessed with a standardized scale. Additional questions evaluated HPV knowledge (including transmission, prevalence, health consequences and treatment), the frequency and type of information sources sought, and trust in those sources. Surveys were collected from 372 OSCC cases (HPV-positive, n=188; HPV-negative, n=184). Despite high mean health literacy scores, only 45.2% of HPV-related knowledge questions were answered correctly. HPV was known to be a sexually transmitted infection and a cause of cervical and anal cancer by 66.0%, 56.5% and 15.2%, respectively. In all domains, cases with HPV-positive OSCC were significantly more informed than HPV-negative cases (for all, pHPV-positive OSCC felt they knew enough to be comfortable discussing HPV with their doctor or sexual partner, respectively. The most frequently used information source was the internet (80.9%), which ranked 8th in trust of 15 possible sources. Although most (95.5%) patients trusted information from their doctors, only 37.9% used doctors as an information source. Doctors are a highly trusted, but infrequent utilized, information source and should facilitate patient access to high-quality HPV information sources. Copyright © 2016. Published by Elsevier Ltd.

  1. Star-PAP controls HPV E6 regulation of p53 and sensitizes cells to VP-16.

    2014-02-13

    Cervical cancer is the most common genital malignancy and the high-risk human papillomaviruses (HPV type 16, 18 and 31, and so on) are major agents for its cause. A key switch for the onset of cervical cancers by HPVs is the cellular degradation of the tumor-suppressor p53 that is mediated by the HPV-generated E6 protein. E6 forms a complex with the E3 ubiquitin-ligase E6-associated protein (E6AP) leading to p53 degradation. The components that control E6 expression and the mechanisms for regulation of the expression in host cells remain undefined. Here we show that the nuclear noncanonical poly(A) polymerase (PAP) speckle targeted PIPKIα regulated PAP (Star-PAP) controls E6 mRNA polyadenylation and expression and modulates wild-type p53 levels as well as cell cycle profile in high-risk HPV-positive cells. In the absence of Star-PAP, treatment of cells with the chemotherapeutic drug VP-16 dramatically reduced E6 and increased p53 levels. This diminished both cell proliferation and anchorage-independent growth required for cancer progression, indicating a synergism between VP-16 treatment and the loss of Star-PAP. This identifies Star-PAP as a potential drug target for the treatment of HPV-positive cancer cells. These data provide a mechanistic basis for increasing the sensitivity and efficiency of chemotherapy in the treatment of cancers that have low levels of wild-type p53.

    2004-11-01

    Full Text Available Three women with large, mutilating genital ulcers of long duration, destroying almost the lower half of the external genitalia, are reported. They had a history of recurrent oral ulcers as well. All patients had been diagnosed as having ′genital ulcer syndrome′ in the past and had been treated with antimicrobials. Histopathology of the biopsy from the margin of the ulcer revealed features of leukocytoclastic vasculitis. Considering the history, clinical features and histology, a diagnosis of bipolar aphthosis was made in all patients. All patients responded well to immunosuppressive therapy. The cases are reported because of the presence of genital ulcers of an unusually large size, mutilating character and their close similarity to genital ulcers due to sexually transmitted diseases, especially genital herpes and donovanosis.

    A half billion people have genital herpes infections worldwide. Approximately one-fifth of American women between ages 14 and 49 are HSV-2 seropositive. The development of an effective genital herpes vaccine is a global health necessity based on the mental anguish genital herpes causes for some individuals, the fact that pregnant women with genital herpes risk transmitting infection to their newborn children, and the observation that HSV-2 infection is associated with a 3-fold to 4-fold increased probability of HIV acquisition. We review the strengths and limitations of preclinical animal models used to assess genital herpes vaccine candidates and the goals of prophylactic and therapeutic vaccines. We also discuss the current pipeline of vaccine candidates and lessons learned from past clinical trials that serve as a stimulus for new strategies, study designs and endpoint determinations.

    While the use of endovaginal ultrasound probes is increasing, the risk of contamination of women with endocavity vaginal probes was not assessed. In particular, the clinical significance of detection of human papillomavirus (HPV) infection, the most common sexually transmitted viral infection, on endovaginal ultrasound probes is uncertain. The recommendations of good practice for decontamination of these probes developed by the High Council for Public Health and the Academy of Medicine have not been evaluated. The objective of this article was to review recent publications concluding to the detection of HPV and human cellular DNA after gynecological examination and disinfection of vaginal ultrasound probes.

    Vaccines against specific types of human papillomavirus (HPV) linked to cancer and other diseases have been met with mixed acceptance globally and in the United States. Policy-level interventions have been shown to be effective in increasing public health benefit. Government policies and mandates may result in improved HPV vaccination coverage and reduced disease burden, and alternative policies that improve unhindered access to HPV vaccination may allow success as well. The purpose of this commentary is to summarize policy efforts to maximize the public health benefit of HPV vaccination. We examine selected examples of HPV vaccination policy in global contexts and in the United States.

    Due to high cervical cancer rates and limited research on human papillomavirus (HPV) vaccine acceptability in India, the research team examined parental attitudes toward HPV vaccines. Thirty-six interviews with parents were conducted to assess sexually transmitted infection (STI)-related knowledge and HPV-specific vaccine awareness and acceptability. Despite limited knowledge, parents had positive views toward HPV vaccines. Common barriers included concerns about side effects, vaccine cost, and missing work to receive the vaccine. Parents were strongly influenced by health care providers' recommendations. Our findings suggest that addressing parental concerns, health worker training and polices, and efforts to minimize cost will be central to successful HPV vaccine implementation.

    Studies specifically conducted to assess gender differences in genital lichen sclerosus (GLS) are not available. This multicenter study aimed to identify possible gender-related differences on GLS clinical features, history and course, through collecting data from a large mixed-sex sample of patients. This was a cross-sectional study on 729 subjects (53.8% females, 46.2% males) affected with GLS, consecutively observed within a network of 15 Italian dermatology units. The following information was specifically collected: clinical features and severity of symptoms related to GLS, extragenital involvement, previous therapies, diagnostic suspicion at referral, type of referring physicians, development of genital squamous-cell carcinoma (SCC). Females complained of symptoms more frequent and severe than men; pallor and scarring-sclerosis-atrophy were the most frequent features without gender differences; itching- related signs were more frequent in females than in males as well as extragenital involvement; prior to receiving a definitive diagnosis, females received treatment more frequently than males; 40% of patients were referred with a misdiagnosis; the highest rate of correct suspected diagnosis at referral came from dermatologists than from other physicians; duration of the disease was found to predispose to SCC development. Our findings highlighted several gender differences on clinical presentation and symptom profile of GLS. In spite of some characteristic features, misdiagnosis at referrals was frequent.

  10. Female sexual dysfunction in female genital mutilation.

    2016-01-01

    Female genital mutilation (FGM), otherwise known as female genital cutting (FGC), is currently very topical and has become a significant global political issue. The impact of FGM on the lives of women and girls is enormous, as it often affects both their psychology and physical being. Among the complications that are often under-reported and not always acknowledged is female sexual dysfunction (FSD). FSD presents with a complex of symptoms including lack of libido, arousability and orgasm. This often occurs in tandem with chronic urogenital pain and anatomical disruption due to perineal scarring.To treat FSD in FGM each woman needs specifically directed holistic care, geared to her individual case. This may include psychological support, physiotherapy and, on occasion, reconstructive surgery. In many cases the situation is complicated by symptoms of chronic pelvic pain, which can make treatment increasingly difficult as this issue needs a defined multidisciplinary approach for its effective management in its own right. The problems suffered by women with FGM are wholly preventable, as the practice need not happen. The current global momentum to address the social, cultural, economic and medical issues of FGM is being supported by communities, governments, non-governmental agencies (NGOs) and healthcare providers. It is only by working together that the practice can be abolished and women and girls may be free from this practice and its associated consequences. © The Author(s) 2016.

Results: The sensitivities of abnormal vaginal discharges, genital rashes, urethral discharges and painful genital ulcers were 82.3%, 70.6%, 41.2% and 28.6% respectively; while their positive-predictive values were 53.8%, 60.0%, 58.3% and 66.7% respective. All the symptoms had >95% specificities and 95% negative-predictive values for seroincident HSV-2 infection. Conclusions: Abnormal vaginal discharge, genital rashes, urethral discharges and genital ulcers are valid indicators of seroincident HSV-2 infection and could be useful in formulation of screening tools in resource-limited settings.

    Despite the fact that HPV-driven oropharyngeal cancer (HPV-OPC) has relatively low recurrence rates, intensive post-therapy monitoring remains the standard of care. Post-treatment biomarkers are needed to risk stratify HPV-OPC patients for more individualized surveillance intensity and which remain at higher recurrence risk. 115 HPV-OPC patients (ascertained by p16 immunohistochemistry and/or in-situ hybridization) from a multicenter prospective case study (HOTSPOT) had blood collected at diagnosis, and 64 of these also had blood collected at post-treatment follow-up visits for up to two years. Samples were centrally tested for antibodies to the L1, E1, E2, E4, E6, and E7 proteins of HPV16. At diagnosis, most HPV-OPC cases were seropositive to HPV16 E6 (85%). In post therapeutic samples, HPV16 antibody level decreased slowly over time, but only 3 (of 51 cases seropositive at enrollment) dropped low enough to be classified as seronegative. At 3years after diagnosis, cumulative risk of recurrence was 10.2% and 0% in HPV16 E6 seropositive and E6 seronegative HPV-OPC cases, respectively (p=0.18). Risk of recurrence was increased, although not statistically significant, in those with higher HPV16 E6 antibody levels at diagnosis (per log antibody level, hazard ratio [HR]=1.81, 95%CI=0.47-6.92). This study confirms the high seroprevalence of HPV oncogenic antibodies at diagnosis of HPV-OPC. HPV16 E6 antibody levels decrease after treatment, but most cases remain seropositive for up to two years. HPV16 E6 antibody levels at diagnosis did not appear to be a strong predictor of recurrence.

    Primary human papillomavirus (HPV) cervical screening is due to be implemented in England within the next 2 years; however, the acceptability of HPV testing as the primary screening test is unclear. This study explores women's awareness and attitudes toward HPV testing/screening. Qualitative interviews (semistructured and focus group) were conducted with 46 women (aged 25-65 years) from community and secondary care settings. Data were analyzed by using the inductive-framework method. Women were unaware that cervical screening currently includes HPV testing and lacked HPV-related knowledge. Emotions of shock, fear, and anxiety were reported upon receiving a positive HPV result. For women in long-term relationships, the realization that HPV is a sexually transmitted infection was seen as a barrier to primary HPV testing. Knowledge that HPV testing is a screening test to prevent cervical cancer did not change their attitudes. Women debated the need for continued screening following a negative result. Women feared judgment by the community if they participated with primary HPV screening because they were being tested for a sexually transmitted infection, with the possible attendant perception that they had adopted a high-risk lifestyle in comparison to nonattenders. The acceptability of HPV testing may be a limiting factor in encouraging participation with screening in the future. Copyright © 2018 John Wiley & Sons, Ltd.

    Human papilloma virus (HPV) affects both men and women; however, recommendations for HPV vaccination among men were not issued in the United States until 2011. The purpose of this study was to describe and compare characteristics of men who did and did not report receiving at least one dose of the HPV vaccine. Data from the ten states that completed the HPV vaccination module in the 2013 Behavioral Risk Factor Surveillance System (BRFSS) were included in the study. Young men ages 18-26 were included (N = 1624). Categorical variables were compared between those who did and did not receive the HPV vaccine using Chi square. Logistic regression was used to examine the odds of HPV vaccination by the above factors. Only 16.5% of men reported at least one dose of HPV vaccine. Having health insurance, having a primary doctor, and receiving an HIV test were predictive of HPV vaccination. Men in Texas were more likely to report HPV vaccination than all other states. Overall, HPV vaccination is low in men. Targeted interventions for improving HPV vaccination rates in men are warranted, especially for those without health insurance or a routine source of care.

    Using a large, population-based survey, we assessed the levels and correlates of human papillomavirus (HPV) awareness among Scandinavian women after introduction of HPV vaccination. In 2011-2012, a random sample of women aged between 18 and 45 years from Denmark, Sweden and Norway received...... a questionnaire on lifestyle, health and HPV awareness. We included 47 895 women (response rate 60.6%) in our study. Country-specific and age-specific proportions of women who had heard of HPV in 2011-2012 (postvaccination survey) were compared with corresponding proportions in an identical survey from 2004......-2005 (prevaccination survey, n=54 079, response rate 71.3%). Correlates of HPV awareness in the postvaccination survey were assessed by logistic regression. In all countries and age groups, awareness of HPV increased from the prevaccination to the postvaccination survey. In the postvaccination survey, HPV awareness...

    The purpose of this study was to determine the feasibility of human Papillomavirus (HPV) testing alone as a prognostic tool to predict recurrent disease within a three-year follow-up period after treatment for cervical intraepithelial neoplasia (CIN)2 + . Retrospectively, 128 women with histologically verified CIN2 + who had a conization performed at Southern Jutland Hospital in Denmark between 1 January 2013 and 31 December 2013 were included. Histology, cytology and HPV test results were obtained for a three-year follow-up period. 4.7% (6/128) of the cases developed recurrent disease during follow-up. Of the cases without free margins, recurrent dysplasia was detected normal in 10.4% (5/48), whereas in the group with free margins it was 1.3% (1/80). The post-conization HPV test was negative in 67.2% (86/128) and Pap smear normal in 93.7% (120/128). Combining resection margins, cytology and HPV had sensitivity for prediction of recurrent dysplasia of 100%. Specificity was 45.8%, positive predictive value (PPV) 8.5% and negative predictive value (NPV) 100%. Using HPV test alone as a predictor of recurrent dysplasia gave a sensitivity of 83.3%, specificity 69.7%, PPV 11.9% and NPV 98.8%. Combining resection margin and HPV test had a sensitivity of 100%, specificity 45.9%, PPV 8.3% and NPV 100%. HPV test at six months control post-conization gave an NPV of 98.8% and can be used as a solitary test to identify women at risk for recurrent disease three years after treatment for precursor lesions. Using both resection margin and HPV test had a sensitivity of 100% and NPV 100%. Adding cytology did not increase the predictive value. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

    Vitiligo has a major effect on sexual health because of the disfiguring skin lesions affecting self-image and self-esteem. However, this topic has not explored. This article aimed to assess the effect of vitiligo on genital self-image, sexual function, and quality of life in female patients. This cross-sectional study included 50 sexually active women with vitiligo and 25 women without vitiligo. All participants subjected to full history taking and examination. Extent of vitiligo was assessed with the Vitiligo Area Scoring Index score, sexual function with the Female Sexual Function Index, genital self-image with Female Genital Self-Image Score and quality of life with the Dermatology Life Quality Index questionnaires. The main outcome measures were correlation between Vitiligo Area Scoring Index, Female Genital Self-Image Score, Female Sexual Function Index, and Dermatology Life Quality Index domains was determined using t test and Pearson correlation. This study revealed a negative correlation between the Vitiligo Area Scoring Index score and sexual satisfaction. Vitiligo Area Scoring Index and Dermatology Life Quality Index score was significantly correlated with Arabic Version of the Female Genital Self-Image Score alone and with Arabic Version of the Female Sexual Functioning Index alone and with both the Arabic Version of the Female Genital Self-Image Score and the Arabic Version of the Female Sexual Functioning Index (p <.05). Sexual and psychological assessment of patients with vitiligo is imperative to improve outcomes and increase patients' compliance with treatment.

    The success of future human papillomavirus (HPV) vaccination programs will depend on individuals' willingness to accept vaccination, parents' willingness to have their preadolescent and early adolescent children vaccinated, and health care providers' willingness to recommend HPV vaccination. The purpose of this article is to provide a qualitative review of the relevant literature, including research on knowledge and attitudes about HPV infection and its clinical sequelae, the acceptability of HPV vaccination to individuals and parents, and health care providers' attitudes about recommending HPV vaccination. Additionally, strategies are suggested by which providers of adolescent health care can discuss and recommend HPV vaccines with parents and their children. The research published to date suggests that there is a good deal of misunderstanding about HPV infection, cervical cancer screening, and the sequelae of HPV infection. However, the majority of research studies to date indicate that young women, parents, and health care providers are interested in vaccines that prevent HPV and other sexually transmitted infections (STIs). Of particular note are the consistent findings that providers are less comfortable vaccinating younger versus older adolescents and that endorsement of vaccination by a professional organization is of great importance. Furthermore, r
