Facilitators and barriers of HPV vaccination: a qualitative study in rural Georgia

IntroductionHuman papillomavirus (HPV) vaccination protects against HPV-associated cancers and genital warts. Healthy People 2030 goal for HPV vaccine uptake is 80%, but as of 2021, only 58.5% of adolescents are up to date in Georgia. The purpose of the study is to assess the attitudes, vaccine practices, facilitators, and barriers to receiving the HPV vaccine in southwest Georgia.MethodsWe conducted 40 semi-structured interviews in the United States from May 2020-Feburary 2022 with three different audiences (young adults, parents, and providers and public health professionals) guided by the P3 (patient-, provider-, practice-levels) Model. The audiences were recruited by multiple methods including fliers, a community advisory board, Facebook ads, phone calls or emails to schools and health systems, and snowball sampling. Young adults and parents were interviewed to assess their perceived benefits, barriers, and susceptibility of the HPV vaccine. Providers and public health professionals were interviewed about facilitators and barriers of patients receiving the HPV vaccine in their communities. We used deductive coding approach using a structured codebook, two coders, analyses in MAXQDA, and matrices.ResultsOut of the 40 interviews: 10 young adults, 20 parents, and 10 providers and public health professionals were interviewed. Emerging facilitator themes to increase the uptake of the HPV vaccine included existing knowledge (patient level) and community outreach, providers’ approach to the HPV vaccine recommendations and use of educational materials in addition to counseling parents or young adults (provider level) and immunization reminders (practice level). Barrier themes were lack of knowledge around HPV and the HPV vaccine (patient level), need for strong provider recommendation and discussing the vaccine with patients (provider level), and limited patient reminders and health education information around HPV vaccination (practice level). Related to socio-ecology, the lack of transportation and culture of limited discussion about vaccination in rural communities and the lack of policies facilitating the uptake of the HPV vaccine (e.g., school mandates) were described as challenges.ConclusionThese interviews revealed key themes around education, knowledge, importance of immunization reminders, and approaches to increasing the HPV vaccination in rural Georgia. This data can inform future interventions across all levels (patient, provider, practice, policy, etc.) to increase HPV vaccination rates in rural communities.

Distribution of HPV types among women with HPV-related diseases and exploration of lineages and variants of HPV 52 and 58 among HPV-infected patients in China: A systematic literature review

ABSTRACT To summarize the distribution of types of human papillomavirus (HPV) associated with HPV-related diseases and investigate the potential causes of high prevalence of HPV 52 and 58 by summarizing the prevalence of lineages, sub-lineages, and mutations among Chinese women. We searched PubMed, EMBASE, CNKI, and WanFang from January, 2012 to June, 2023 to identify all the eligible studies. We excluded patients who had received HPV vaccinations. Data were summarized in tables and cloud/rain maps. A total of 102 studies reporting HPV distribution and 15 studies reporting HPV52/HPV58 variants were extracted. Among Chinese women, the top five prevalent HPV types associated with cervical cancer (CC) were HPV16, 18, 58, 52, and 33. In patients with vaginal cancers and precancerous lesions, the most common HPV types were 16 and 52 followed by 58. For women with condyloma acuminatum (CA), the most common HPV types were 11 and 6. In Chinese women with HPV infection, lineage B was the most prominently identified for HPV52, and lineage A was the most common for HPV58. In addition to HPV types 16, which is prevalent worldwide, our findings revealed the unique high prevalence of HPV 52/58 among Chinese women with HPV-related diseases. HPV 52 variants were predominantly biased toward lineage B and sub-lineage B2, and HPV 58 variants were strongly biased toward lineage A and sub-lineage A1. Further investigations on the association between the high prevalent lineage and sub-lineage in HPV 52/58 and the risk of cancer risk are needed. Our findings underscore the importance of vaccination with the nine-valent HPV vaccine in China.

CLINICAL CHARACTERISTICS AND THE QUALITY OF LIFE OF PATIENTS WITH GENITAL WARTS

Background: Genital warts are a disease with the highest proportion of sexually transmitted diseases, which are caused by Human Papillomaviruses. Currently, research on the impact on the quality of life of patients with genital warts in Vietnam is still very limited, while this is an issue that deserves attention and has been studied in many places around the world. Objectives: To describe the clinical characteristics and evaluate the quality of life of patients with genital warts at Can Tho Dermato-Venereology Hospital in 2023. Materials and methods: A cross-sectional descriptive study was conducted at Can Tho City Hospital of Dermato-Venereology, including 111 patients who were diagnosed with genital warts and treated. The generic questionnaire European quality of life index version 5D (EQ-5D), and EQ visual analogue scale (EQ-VAS) have been used to assess the quality of life of patients with genital warts. The period of study is from May 2023 to October 2023. Results: Patients in the 14-35 age group accounted for the highest proportion (81.1%), and the over 60-year-old group accounted for the lowest proportion (2.7%). The majority of patients participating in the study were female (61.3%). Types of lesions included sharp papules (78.4%), papular papules (12.6%), keratinized papules (6.3%), and flat papules (2.7%). The mild and moderate disease severity were dominant (79.28%). Genital warts usually do not affect mobility, self-care, or usual activities; however, this disease causes pain or discomfort (59.46%), and anxiety or depression (62.16%). The average general health score according to the EQ-VAS, was 74.6 ± 9.031. There was a relationship between EQ-VAS and disease severity (p<0.002). The more severe the disease was, the lower the average EQ-VAS score was. Conclusion: Genital warts had a negative impact on many aspects of the patient's quality of life, including anxiety or depression, varying from moderate to severe levels. Therefore, in addition to consulting and raising awareness, paying attention to monitoring the problems above is extremely important in treatment.

Elevated risk of sexually transmitted infections among adolescents and young adults with borderline personality disorder: a retrospective longitudinal nationwide population-based study.

In this study, we examined the risk of sexually transmitted infections (STIs) among adolescents and young adults (AYAs) with borderline personality disorder (BPD). A total of 4649 AYAs with BPD and 46,490 age-, sex-, and socioeconomic-matched controls without BPD were enrolled from the National Health Insurance Research Database of Taiwan from 2001 to 2009 and were followed up until the end of 2011. Participants who contracted any STI during the follow-up period were identified. Cox regression analysis was conducted to examine the risk of contracting any STI among both patients and controls. A total of 4649 AYAs with BPD and 46,490 age-, sex-, and socioeconomic-matched controls without BPD were enrolled from the National Health Insurance Research Database of Taiwan from 2001 to 2009 and were followed up until the end of 2011. Participants who contracted any STI (ICD-9-CM code 042, 091-097, 087.11, 078.8, 078.88, 131, and 054.1) during the follow-up period were identified. Cox regression and sub-analyses stratified by sex, age, psychiatric comorbidity subgroups, and psychotropic medication usage were conducted to assess STI risk. AYAs with BPD were at a higher risk of contracting any STI (hazard ratio [HR] = 50.79, 95% confidence interval [CI] = 33.45-77.11) in comparison with controls, including HIV, syphilis, genital warts, gonorrhea, chlamydia, trichomoniasis, and genital herpes. The association of BPD with an increased risk of any STI was prevalent in both sexes, adolescents, and young adult patients. BPD with or without psychiatric comorbid subgroup were all associated with an elevated risk of contracting any STI relative to the control group. AYAs with BPD are highly susceptible to contracting STIs. Future studies should examine the role of the core symptoms of BPD, sexual orientation, risky sex behaviors, depressive and anxiety symptoms, and substance use before sex in the risk of STIs among AYAs with BPD.

Effect of an HPV Vaccination Multi-Level, Multi-Component Program on HPV Vaccination Initiation and Completion in a Pediatric Clinic Network.

Despite clear evidence of the public health benefits of the human papillomavirus (HPV) vaccine in preventing HPV-related cancers and genital warts, underutilization of HPV vaccination in the United States persists. Interventions targeting multi-level determinants of vaccination behavior are crucial for improving HPV vaccination rates. The study's purpose was to implement and evaluate the adapted Adolescent Vaccination Program (AVP), a clinic-based, multi-level, multi-component intervention aimed at increasing HPV vaccine initiation and completion rates in a five-clinic pediatric network in Bexar County, Texas. The adaptation process was guided by established frameworks and involved formative work with clinic stakeholders. The study utilized a quasi-experimental single group pre- and post- study design, with an external comparison data using the National Immunization Survey-Teen (NIS-Teen) datasets for the same time period to examine the AVP's effect on HPV vaccination initiation and completion. A series of interrupted time series analyses (ITSA) compared the clinic system patient outcomes (HPV vaccination initiation and completion rates) in the post-intervention to the general adolescent population (NIS-Teen). Of the 6438 patients (11-17 years) with clinic visits during the 3-year study period, HPV vaccination initiation rates increased from 64.7% to 80.2% (p < 0.05) and completion rates increased from 43.2% to 60.2% (p < 0.05). The AVP was effective across various demographic and economic subgroups, demonstrating its generalizability. ITSA findings indicated the AVP improved HPV vaccination initiation and completion rates in clinic settings and that AVP strategies facilitated resilience during the pandemic. The minimal adaptation required for implementation in a new clinic system underscores its feasibility and potential for widespread adoption.

Factors Associated With Recent Decline in Anal Health Among Older Gay and Bisexual Men: A Cross-sectional Analysis.

We investigated factors associated with "worse than usual" anal health among gay and bisexual men aged ≥35 years recruited to a longitudinal study of anal human papillomavirus infection/lesions from September 2010 to August 2015.Among 616 participants (median age 49 years; 36% HIV-positive), 42 (6.8%) reported worse than usual anal health in the last 4 weeks. Associated factors included spending less time with gay friends (odds ratio [OR] = 2.25, 95% CI = 1.06-4.77), most time "feeling down"(OR = 9.17, 95% CI = 2.94-28.59), reduced libido (OR = 2.90, 95% CI = 1.52-5.52), current anal symptoms (OR = 6.55, 95% CI = 2.54-16.90), recent anal wart diagnosis (OR = 4.33, 95% CI = 1.98-9.49), and fear of developing anal cancer (OR = 9.34, 95% CI = 4.52-19.28).Concerns regarding anal health should be routinely discussed by clinicians, and potentially associated psychosocial, physical, and sexual issues further explored.

Risks of Infections With Contraceptive Vaginal Rings Compared to No Hormone Use [ID 2683646

INTRODUCTION: Alterations in the vaginal microbiome by hormones, foreign bodies, intercourse, etc., can affect the body’s susceptibility to infection. The effect of combined contraceptive vaginal rings (CCVRs) on the vaginal microbiome needs more study. We aim to explore the outcomes of CCVRs on vaginal health and infection risk when compared to women without hormone use to better understand the effect of these devices. METHODS: De-identified data were collected from TriNetX. Using ICD-10 and RXNorm codes, populations were selected for women receiving etonogestrel and ethinyl estradiol CCVR without segesterone use, versus sexually active women of reproductive age on no hormonal contraceptives. Cohorts were matched for age at index, race, and ethnicity. Statistical analysis within 1 year of CCVR placement using risk ratios (RRs); P&lt;.05 was considered significant. RESULTS: Cohort sizes were 274,743 each. Combined contraceptive vaginal ring usage showed an increased risk of gonorrhea (RR 1.221; P=.012), HSV-2 (RR 1.229; P&lt;.0005), acute vaginitis (RR 1.314; P&lt;.0005), subacute/chronic vaginitis (RR 1.708; P&lt;.0005), acute vulvitis (RR 1.708; P&lt;.0005), subacute/chronic vulvitis (RR 1.722; P&lt;.0005), pelvic inflammatory disease (RR 1.184; P&lt;.0005), anogenital warts (RR 1.314; P&lt;.0005), and candidiasis (RR 1.402; P&lt;.0005) when compared to women receiving no hormonal contraception. Combined contraceptive vaginal ring showed significant decreased risk of chlamydia (RR 0.786; P&lt;.0005), syphilis (RR 0.493; P&lt;.0005), and HIV (RR 0.434; P&lt;.0005). Trichomoniasis was statistically insignificant. CONCLUSION: Women on etonogestrel and ethinyl estradiol CCVRs have an increased risk of gonorrhea, HSV-2, vaginitis, vulvitis, PID, anogenital warts, and candidiasis, with a decreased risk of chlamydia, syphilis, and HIV when compared to women receiving no hormonal contraception. Further investigation could be useful in developing multipurpose prevention technologies.

Correlation of CD4+ levels and caspase-3 in condyloma acuminata with HIV reactive patients

Background: Human papillomavirus is an infection that causes malignancy because of persistency and modulation of apoptotic pathways, especially caspase-3. Factors that can increase persistency, recurrency, and malignancy of HPV infection include HIV infection with low CD4 levels. There is disagreement or deep molecular understanding of the induction and modulation of apoptosis in HIV-mediated CD4+ T cell depletion, especially in CA. However, it is necessary to see how CD4+ levels can influence caspase-3, so it may open up new avenues for supporting investigation to consider the presence of malignancy or therapeutic strategies regarding CD4+ can induce apoptosis.Purpose: This study aimed to determine whether there is a correlation between CD4+ levels and caspase-3 expression in condyloma acuminata with HIV reactive patients.Methods: This is an analytic observational study with a cross-sectional design. The research was conducted at Dr. Moewardi General Hospital from August to December 2023. Nineteen patients with condyloma acuminata and HIV reactive were included in this study with a consecutive sampling technique. The expression of caspase-3 was assessed using immunohistochemical staining, looking at the percentage of stained cell nuclei and cytoplasm and CD4+ levels with flow cytometry examination—data analysis using Pearson correlation.Results: Respondents in this study were primarily men, self-employed with heterosexual orientation and genito-genital-oral sexual intercourse. The statistical analysis showed no significant relationship (p: 0.300, r: -0.251) between CD4+ levels and caspase-3 expression.Conclusions: While not statistically significant, CD4+ level is reduced in correlation with increased caspase-3 expressions.

Pedunculated Giant Condyloma Acuminatum of the Scrotum

The patient was a 71-year-old male whose chief complaint was a scrotum mass. The mass had gradually increased in size without any associated symptoms. The physical examination revealed a pedunculated, radish brown, and elastic soft tumor (4. 5×3. 5×3. 0 cm) in the right scrotum. Blood chemical analysis of HbA1c and squamous carcinoma antigen were 8. 3% and 38. 4 ng/ml (≦1. 5), respectively. This tumor was successfully treated with surgical resection. Histopathological examination showed condyloma acuminatum without malignant findings. Giant condyloma acuminatum commonly affects the genital and perianal areas. An immunocompromised state generally exists in the background of the patients.

Risks of Vaginally and Sexually Transmitted Infections With Contraceptive Vaginal Rings Compared to Oral Contraceptives [ID 2683643

INTRODUCTION: Use of combined contraceptive vaginal ring (CCVR) has been found to upregulate immune-related genes in the endocervix and mediators within the cervicovaginal fluid. Attachment and infection rates of certain pathogens within this tract can vary based on hormones within the local environment. Rat studies have shown treatment with estrogen prior to chlamydial infections was protective. Continued clinical safety analyses are critical as CCVR use continues to increase. We calculated risk of vaginal infections associated with CCVR compared to oral contraceptive pills (OCPs) via retrospective chart review. METHODS: De-identified data was collected from TriNetX. Using ICD-10 and RxNorm codes, study cohorts included women receiving etonogestrel and ethinyl estradiol CCVRs without segesterone, versus women on OCPs without vaginal hormones. Cohorts (n=30,796 each) were matched for age, race, and ethnicity. Statistical analysis within 1 year of CCVR placement used risk ratios (RRs); P&lt;.05 was considered significant. RESULTS: Combined contraceptive vaginal rings showed increased risk of HSV-2 (RR 1.790; P&lt;.0005), acute vaginitis (RR 1.722; P&lt;.0005), subacute/chronic vaginitis (RR 1.904; P&lt;.0005), subacute/chronic vulvitis (RR 1.969; P&lt;.0005), acute vulvitis (RR 1.894; P&lt;.0005), candidiasis (RR 1.464; P&lt;.0005), trichomoniasis (RR 2.162; P&lt;.0005), and pelvic inflammatory disease (PID) (RR 2.984; P&lt;.0005). Combined contraceptive vaginal rings showed a decreased risk of chlamydia (RR 0.760; P=.047). There were no differences in risk of gonorrhea, syphilis, HIV, or anogenital warts between the CCVR and OCP cohorts CONCLUSION: In this chart review, women using CCVRs had increased risks for HSV-2, vaginitis, vulvitis, PID, trichomoniasis, and candidiasis and decreased risk of chlamydia compared to OCPs. Further study of local hormone delivery on the vaginal mucosa is warranted.

The Development and Performance of a Machine-Learning Based Mobile Platform for Visually Determining the Etiology of 5 Penile Diseases

ObjectiveTo develop a machine-learning visual classification algorithm for penile diseases in order to address disparities in access to sexual health services. Patients and MethodsWe developed an image data set using original and augmented images for 5 penile diseases: herpes lesions, syphilitic chancres, balanitis, penile cancer, and genital warts. We used a U-Net architecture model for semantic pixel segmentation into background or subject image, an Inception-ResNet version 2 neural architecture to classify each pixel as diseased or nondiseased, and a salience map using GradCAM++. We trained the model on a random 91% sample of the images and evaluated the model on the remaining 9%, assessing recall (or sensitivity), precision, specificity, and F1-score. As of July 1st 2022, the model has been in use via a mobile application platform; we assessed application usage between July and October 1, 2023. ResultsOf 239 images in the validation data set, 45 (18.8%) were of genital warts, 43 (18%) were of herpes simplex virus infection (ranging from early vesicles to ulcers), 29 (12.1%) were of penile cancer, 40 (16.7%) were of balanitis, 37 (15.5%) were of syphilitic chancres, and 45 (18.8%) were nondiseased images. The overall accuracy of the model for correctly classifying images was 0.944. There were 2640 unique submissions to the mobile platform; among a random sample (n=437), 271 (62%) were from the United States, 64 (14.6%) from Singapore, 41 (9.4%) from Canada, 40 (9.2%) from the United Kingdom, and 21 (4.8%) from Vietnam. ConclusionWe report on the development of a machine-learning model for classifying 5 penile diseases, which exhibited excellent performance.

Optimizing Communication on HPV Vaccination to Parents of 11- to 14-Year-Old Adolescents in France: A Discrete Choice Experiment.

With the aim to optimize communication during HPV vaccination campaigns in France, we elicited parental preferences around HPV vaccination. We conducted a single-profile discrete choice experiment (DCE) among parents of 11- to 14-year-old middle-school pupils, who completed an anonymous, self-administered, internet-based questionnaire during 2020-2021. The DCE comprised five attributes (vaccine-preventable disease, justification of optimal age, information on safety, indirect protection and coverage) of vaccination against an unnamed disease that were presented to respondents in ten choice tasks, or scenarios. We use fixed effect logit models to estimate attribute weights on theoretical vaccine acceptance, and random effect linear regression to estimate attribute coefficients on vaccine eagerness (decision and decision certainty). We estimated marginal effects of attributes on expected vaccine acceptance. Vaccination scenarios were accepted by 55.6-89.2% of the 1291 participants. The largest marginal effects on expected vaccine acceptance in the full sample arose from prevention of cancer versus genital warts (+11.3 percentage points); from a "severe side effect suspicion that was not scientifically confirmed" versus a statement about "more benefits than risks" (+8.9 percentage points), and information on 80% vaccine coverage in neighbouring countries versus on "insufficient coverage" (+4.2 percentage points). Explaining the early age of vaccination by sexual debut had a strong negative impact among French monolingual parents with lower education level (vs age-independent, OR 0.48, 95% CI 0.27-0.86), but not other socio-economic groups. After removing low-quality responses (unvaried certainty and short questionnaire completion), among serial non-demanders with children not vaccinated against HPV, only disease elimination impacted vaccine eagerness positively (coefficient 0.54, 0.06-1.02). Using DCEs to elicit parents' preferences around communication messages, notably on cancer prevention, vaccine coverage and information about vaccine safety, could help to optimize HPV vaccination promotion efforts.

Surgical Management of Giant Condyloma Acuminata Involving Vulva, Perineum and Perianal Area

Condyloma acuminata (CA), also known as anogenital warts, are benign proliferative epidermal and/or mucosal lesions usually caused by Human Papilloma Virus (HPV) type 6 and 11. They initially manifest as variable sized and shaped soft papules or plaques on anogenital skin. However, they can grow as a large, bulky, lobulated growth. Lesions are commonly multiple and multifocal, affecting the vulva, perianal, vaginal and cervical regions. They represent the most common sexually transmitted disease (STD) and are highly contagious. Further, the incidence of CA is 5-7fold higher in Human Immunodeficiency virus (HIV) positive patients compared to immunocompetent patients. The HIV infection reduces the local immune control of HPV infection thus favours the proliferation of the HPV which results into large sized CA. The giant condyloma acuminata (GCA) and giant condyloma of Buschke-Löwenstein (GCBL) are uncommon variants of classical condyloma acuminata (CCA) which can reach the size of 10 to 30 cm. The treatment of CA should be individualized and based upon the extent of disease and treatment availability. The small CA which present as papules or plaques can be treated by Podophyllin, Imiquimod, electrosurgical ablation or cryotherapy. However, GCA require excision with cold knife, electrosurgery or CO2 laser. When the base of GCA is narrow, surgical excision with minimal skin loss allows primary closure of the wound, whereas when the base is broad and relatively fixed, one must keep the differential diagnoses of GCA versus GCBL which require wide excision and reconstruction of the tissue. This case report illustrates the surgical management of GCA with broad base in a 44-year-old female patient with HIV infection. She was treated by wide surgical excision followed by reconstruction of the defect with fascio-cutaneous V-Y advancement flaps. Histology confirmed the diagnosis of condyloma acuminatum. Six months following surgery, she had recurrence of a perianal wart that was cauterized. On further 12 month follow up there was no new recurrence of any condylomatous lesion.

Cryotherapy vs Laser for Genital Warts Management: A Systematic Review

The study compared cryotherapy and laser in managing external genital warts (EGW) using various databases. The research involved eleven studies with 92 patients, with follow-up durations ranging from 28 days to 39 months. One study found that CO2 laser therapy was two times more effective than cryotherapy in terms of clearance, recurrence, and complication rates. Six studies showed that laser was the best option for immunocompromised patients and those who did not respond to cryotherapy, with the lowest recurrence rates and complications. Cryotherapy is economical, effective, and safe, but it is painful, deformed, and requires multiple sessions. Current treatment approaches focus on the surface wart rather than the underlying viral infection, making them less successful in long-term effects. There is little evidence to support the idea that a specific therapy is not more successful than others. Future research should focus on extensive comparisons with larger sample sizes.

Human papillomavirus infection: Epidemiology, biology, host interactions, cancer development, prevention, and therapeutics.

Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections worldwide. It is caused by the HPV, a DNA virus that infects epithelial cells in various mucous membranes and skin surfaces. HPV can be categorised into high-risk and low-risk types based on their association with the development of certain cancers. High-risk HPV types, such as HPV-16 and HPV-18, are known to be oncogenic and are strongly associated with the development of cervical, anal, vaginal, vulvar, penile, and oropharyngeal cancers. These types of HPV can persist in the body for an extended period and, in some cases, lead to the formation of precancerous lesions that may progress to cancer if left untreated. Low-risk HPV types, such as HPV-6 and HPV-11, are not typically associated with cancer but can cause benign conditions like genital warts. Genital warts are characterised by the growth of small, cauliflower-like bumps on the genital and anal areas. Although not life-threatening, they can cause discomfort and psychological distress. HPV is primarily transmitted through sexual contact, including vaginal, anal, and oral sex. It can also be transmitted through non-penetrative sexual activities that involve skin-to-skin contact. In addition to sexual transmission, vertical transmission from mother to child during childbirth is possible but relatively rare. Prevention of HPV infection includes vaccination and safe sexual practices. HPV vaccines, such as Gardasil and Cervarix, are highly effective in preventing infection with the most common high-risk HPV types. These vaccines are typically administered to adolescents and young adults before they become sexually active. Safe sexual practices, such as consistent and correct condom use and limiting the number of sexual partners, can also reduce the risk of HPV transmission. Diagnosis of HPV infection can be challenging because the infection is often asymptomatic, especially in men. In women, HPV testing can be done through cervical screening programs, which involve the collection of cervical cells for analysis. Abnormal results may lead to further diagnostic procedures, such as colposcopy or biopsy, to detect precancerous or cancerous changes. Overall, HPV infection is a prevalent sexually transmitted infection with significant implications for public health. Vaccination, regular screening, and early treatment of precancerous lesions are key strategies to reduce the burden of HPV-related diseases and their associated complications. Education and awareness about HPV and its prevention are crucial in promoting optimal sexual health. This study aimed to carry out a literature review considering several aspects involving HPV infection: Global distribution, prevalence, biology, host interactions, cancer development, prevention, therapeutics, coinfection with other viruses, coinfection with bacteria, association with head and neck squamous cell carcinomas, and association with anal cancer.

Human Papillomavirus and Associated Cancers: A Review.

The human papillomavirus is the most common sexually transmitted infection in the world. Most HPV infections clear spontaneously within 2 years of infection; however, persistent infection can result in a wide array of diseases, ranging from genital warts to cancer. Most cases of cervical, anal, and oropharyngeal cancers are due to HPV infection, with cervical cancer being one of the leading causes of cancer death in women worldwide. Screening is available for HPV and cervical cancer, but is not available everywhere, particularly in lower-resource settings. HPV infection disproportionally affects individuals living with HIV, resulting in decreased clearance, increased development of cancer, and increased mortality. The development of the HPV vaccine has shown a drastic decrease in HPV-related diseases. The vaccine prevents cervical cancer with near 100% efficacy, if given prior to first sexual activity. Vaccination uptake remains low worldwide due to a lack of access and limited knowledge of HPV. Increasing awareness of HPV and access to vaccination are necessary to decrease cancer and HPV-related morbidity and mortality worldwide.

Cervical cancer prevention by vaccination: review.

Routine use of human papillomavirus (HPV) vaccines is recommended in adolescents under 15 years of age worldwide. Still, effective programs remain suboptimal for several factors, making the WHO strategy to eradicate cervical cancer public health with an uncertain future. To review the literature on the effectiveness, long-term protection, and safety of HPV vaccination programs and vaccination as adjuvant management. This review aims to describe the current state of vaccination programs and demonstrate the long-term protection and safety of vaccines implemented worldwide targeting adolescent girls, with the most recent published evidence of the three prophylactic HPV vaccines - bivalent (bHPV), quadrivalent (qHPV), and nonavalent (nHPV)-. We mainly focus on publications evaluating efficacy, dosing schemes, and HPV vaccination, as well as studies contributing to the mounting evidence for the real-life effectiveness of prophylactic HPV vaccines from several countries. Human Papillomavirus vaccination programs have made remarkable strides in preventing HPV-related diseases; countries with robust vaccination efforts have witnessed substantial reductions in HPV-related diseases with a decline in high-grade cervical abnormalities and genital warts (54%-83%). However, global coverage remains uneven, with disparities between high-income (HICs) and low-income countries (LMICs). The long-term efficacy of the available human papillomavirus (HPV) goes up to 9.4 years and continues to be immunogenic and well tolerated with an excellent safety profile. As these are crucial topics in HPV vaccination, it is essential to establish systems for continued monitoring of vaccine immunogenicity, efficacy, and safety over time.

Sustained Decline in Hospitalisations for Anogenital Warts in Australia: Analysis of National Hospital Morbidity Data 2003-2020.

In Australia, school-based human papillomavirus (HPV) vaccination was introduced initially for girls in 2007, and then also for boys in 2013. While studies have shown declines in the incidence of anogenital warts, there is a paucity of recent data analysis assessing the impact of vaccination on more severe disease. The National Hospital Morbidity Database of the Australian Institute of Health and Welfare (AIHW) hospitalisation admission data that included ICD-10-AM code A63.0 ('anogenital warts') as the diagnoses, for the years 2003-2020, were analysed to estimate hospitalisation rates per 100,000 mid-year population. The annual average hospitalisation rates per 100,000 population for anogenital warts in both genders combined in the age groups 10-19 years, 20-29 years, and 30-39 years decreased, respectively, from 16.9, 49.6, and 23.6 in 2003-2007 (pre-vaccine period) to 2.6, 15.2, and 14.6 in 2008-2020 (post-vaccine period), equating to declines of 84.7%, 69.4%, and 38.2%, respectively. Following the introduction of the boy's vaccination, hospitalisation rates decreased further in the respective age bands from 4.3, 22.8, and 18.4 in 2008-2013 (early post-vaccine period) to 1.1, 9.3, and 11.7 in 2014-2020 (late post-vaccine period), equating to respective declines of 73.4%, 59.3%, and 36.4%. This analysis confirms that there is a substantial incremental decline in anogenital warts hospitalisations among Australians aged 10-39 years.

Structured Literature Review to Identify Human Papillomavirus's Natural History Parameters for Dynamic Population Models of Vaccine Impacts.

Human papillomavirus (HPV) is a common sexually transmitted virus that can cause cervical cancer and other diseases. Dynamic transmission models (DTMs) have been developed to evaluate the health and economic impacts of HPV vaccination. These models typically include many parameters, such as natural history of the disease, transmission, demographic, behavioral, and screening. To ensure the accuracy of DTM projections, it is important to parameterize them with the best available evidence. This study aimed to identify and synthesize data needed to parametrize DTMs on the natural history of HPV infection and related diseases. Parameters describing data of interest were grouped by their anatomical location (genital warts, recurrent respiratory papillomatosis, and cervical, anal, vaginal, vulvar, head and neck, and penile cancers), and natural history (progression, regression, death, cure, recurrence, detection), and were identified through a systematic literature review (SLR) and complementary targeted literature reviews (TLRs). The extracted data were then synthesized by pooling parameter values across publications, and summarized using the range of values across studies reporting each parameter and the median value from the most relevant study. Data were extracted and synthesized from 223 studies identified in the SLR and TLRs. Parameters frequently reported pertained to cervical cancer outcomes, while data for other anatomical locations were less available. The synthesis of the data provides a large volume of parameter values to inform HPV DTMs, such as annual progression rates from cervical intraepithelial neoplasia (CIN) 1 to CIN2+ (median of highest quality estimate 0.0836), CIN2 to CIN 3+ (0.0418), carcinoma in situ (CIS) 2 to local cancer+ (0.0396), and regional to distant cancer (0.0474). Our findings suggest that while there is a large body of evidence on cervical cancer, parameter values featured substantial heterogeneity across studies, and further studies are needed to better parametrize the non-cervical components of HPV DTMs.

Fine scalpel surgery: preserving the dartos muscle in apatient with scrotal and perigenital giant Buschke-Löwenstein tumors.

Giant condyloma acuminatum (GCA), alternatively referred to as aBuschke-Löwenstein tumor (BLT), is an uncommon, benign, but locally aggressive form of verrucous carcinoma. The condition usually affects the male population under the age of50years; however, there have been rare reports of pediatric cases. Various risk factors such as smoking, diabetes, promiscuous behavior, poor hygiene, immunosuppression, and others are linked to the development of this condition. We present the case of a26-year-old male patient who came to the dermatology department with primary complaints of 10-year-old verrucous tumor formations located in the perigenital and perianal areas. Serological tests for AIDS, hepatitisB, hepatitisC, Chlamydia trachomatis, and syphilis were negative. The routine blood tests were slightly abnormal. Histological verification of condylomata acuminata of Buschke-Löwenstein was made. Given the sensitive areas, surgery was advised. With several fine undermining scalpel excisions, the lesions in the scrotal and perigenital areas were removed and the dartos muscle was preserved. Electrodissection and shave curettage were not performed. The postoperative period passed without complications and no recurrences in the perigenital area were reported. We believe that our case report represents the first documented surgical approach for scrotal Buschke-Löwenstein tumor using exclusively fine undermining scalpel surgery. Abrief literature review of the condition is presented, focusing on the currently available treatment options and highlighting the potential effectiveness of the surgical approach.
