Genital HPV in Children and Adolescents: Does Sexual Activity Make a Difference?

Molecular Detection of HPV, EBV, HSV-1, HCMV, and H. pylori Pathogens: An Evaluation among Polish Children with Molar Incisor Hypomineralization (MIH)

Molar incisor hypomineralization (MIH) is a congenital disorder of the enamel tissue, characterized by a quantitative deficiency. In childhood, infections such as EBV, HSV-1, HCMV, or H. pylori may occur and cause various diseases. This study aimed to investigate the prevalence of HPV, EBV, HSV-1, HCMV, and H. pylori infections in two groups of children: children with molar incisor hypomineralization (MIH) and a control group, using molecular methods. The study group included 47 children aged between 6-13 years who had been diagnosed with MIH. The control group consisted of 42 children. The study found that, in the MIH group, the prevalence of HPV-16 was 6.38%, HPV-18 was 4.26%, EBV was 31.91%, HSV-1 was 4.26%, HCMV was 4.26%, and H. pylori was 12.77%. There were no significant differences in the prevalence of any of tested pathogens between the study and the control group (p > 0.05). However, the study found a higher prevalence of EBV infection in children who had smallpox/pneumonia by the age of 3 years. Ten children were found to have at least two pathogens present. Moreover, both groups had a high prevalence and activity of EBV. These findings provide new insights into the carriage of pathogens among children with MIH, providing new information for parents, scientists, and healthcare professionals.

Interpretation of medical findings in suspected child sexual abuse: An update for 2023

Health care professionals who examine children who may have been sexually abused need to be able to recognize, and photo-document any physical signs, and to have access to expert reviewers, particularly when signs concerning for sexual abuse are found. Although the general consensus among practitioners is that children will show few signs of sexual abuse on examination, there is considerable variability and rates of positive exam findings among practitioners of different professions, practice settings, and countries. This review will summarize new data and recommendations regarding the interpretation of medical findings and sexually transmitted infections (STIs); assessment and management of pediatric patients presenting with suspected sexual abuse or assault; and testing and treating patients for STIs. Updates to a table listing an approach to the interpretation of medical findings are presented, and reasons for changes are discussed.

Epidemiological characteristics and transmissibility of HPV infection: A long-term retrospective study in Hokkien Golden Triangle, China, 2013-2021

OBJECTIVE

Multiple human papillomavirus (HPV)-associated diseases have put a significant disease burden on the world. Therefore, we conducted a study to explore the epidemiological characteristics of HPV and the transmissibility of its genotypes.

METHODS

HPV testing data was collected from Hospital. A transmission dynamics model of HPV was constructed to simulate and compare the transmissibility of different HPV genotypes, which was quantitatively described by the basic reproduction number (R0).

RESULTS

The collected HPV subjects were mainly from Xiamen City, Zhangzhou City and Quanzhou City, together, they are known as the Hokkien golden triangle. There were variations in the distribution of HPV infections by age groups. Among all HPV genotypes, 13 of them had R0 > 1, with 10 of them being high-risk types. The top five were HPV56, 18, 58, 52 and 53, among which, HPV56, 18, 58 and 42 were of high risk, whereas HPV53 was not, and the R0 values for the five were 3.35 (CI: 0.00-9.99), 3.20 (CI: 0.00-6.46), 3.19 (CI: 1.27-6.94), 3.19 (CI: 1.01-8.42) and 2.99 (CI: 0.00-9.39), respectively. In addition, HPV52 had R0 > 1 for about 51 months, which had the longest duration.

CONCLUSION

Most high-risk HPV types in the Hokkien golden triangle could transmit among the population. Therefore, there is a need of further optimization for developing HPV vaccines and better detection methods in the region.

Knowledge about HPV Infection and the HPV Vaccine among Parents in Southeastern Serbia

Background and Objectives: The vaccine against human papilloma virus (HPV) infection is recommended, according to the Serbian National Immunization Program, for children and adolescents aged 9−19 years. Three doses are given keeping in mind the recommendation that the second dose should be administered at least one month after the first dose, and the third at least three months after the second dose. No children who participated in this first study received the third dose because they did not meet these criteria. The study explored parents’ knowledge about HPV infection and their awareness of the HPV vaccine. Materials and Methods: A cross-sectional questionnaire-based study was carried out in the city of Nis, in southeastern Serbia. According to the 2011 population census, the sample of children aged 9 to 19 was 850, and during the observed period, 631 children received the vaccine. A total of 615 fully completed questionnaires filled out by parents were included in the study. The study was carried out from 6 June 2022 to 7 October 2022. Multivariable logistic regression analysis was used. The odds ratio (OR) and 95% confidence intervals (CI) were calculated. The statistical significance was p < 0.05. Results: A total of 615 children were included in the study (499 were vaccinated with the first dose and 116 with the second). Out of 499 children vaccinated with the first dose, 398 (79.6%) were girls, which is significantly higher than the rate for boys (101). The independent variable sex was statistically significant at the level of p = 0.84, OR = 2.664 (95% CI from 0.879 to 7.954). Boys are 164% less likely to be vaccinated with the HPV vaccine than girls. We determined that the independent variable place of residence was significant at the level of p = 0.041, (OR = 3.809, 95% CI from 1.702 to 8.525). Based on these findings, we determined that parents who came from rural areas were 82% less likely to know about HPV infection and HPV vaccination. Children under 15 years of age were significantly more vaccinated than those ≥15 years (OR = 3.698, 95% CI from 1.354 to 12.598). The independent variable parental education was significant at the level of OR = 0.494, 95% CI from 0.301 to 0.791. Parents who had medical education showed significantly higher awareness about the infection caused by HPV and about the HPV vaccine (p = 0.004) than parents with no medical education. The possibility that a parent would decide to vaccinate a child significantly increased upon a pediatrician’s recommendation, p = 0.000 with OR = 0.250 (95% CI from 0.127 to 0.707). Health insurance coverage of HPV vaccination for children aged 9−19 years significantly increased the probability of a positive parental decision to vaccinate a child, p = 0.001 with OR = 3.034 (95% CI from 1.063 to 8.662). Conclusion: We identified several significant factors that were important for HPV vaccination such as: children under 15 years, female sex, urban place of residence, medical education of parents, pediatrician’s recommendation of the HPV vaccination, and HPV vaccination free of charge. Health education and the promotion of HPV vaccination as well as healthy sexual behavior are important factors in the preservation and improvement of the health of the whole population.

Risk factors on testicular function in adolescents

PURPOSE

Adolescence represents an important window for gonadal development. The aim of this review is to carry out a critical excursus of the most recent literature on endogenous and exogenous risk factors related to testicular function, focusing the research on adolescence period.

METHODS

A comprehensive literature search within PubMed was performed to provide a summary of currently available evidence regarding the impact on adolescence of varicocele, cryptorchidism, cancer, diabetes, lifestyle factors, endocrine disruptors, obesity and sexually transmitted diseases. We focused on human studies that evaluated a possible impact of these factors on puberty timing and their effects on andrological health.

RESULTS

Evidence collected seems to suggest that andrological health in adolescence may be impaired by several factors, as varicocele, cryptorchidism, and childhood cancer. Despite an early diagnosis and treatment, many adolescents might still have symptoms and sign of a testicular dysfunction in their adult life and at the current time it is not possible to predict which of them will experience andrological problems. Lifestyle factors might have a role in these discrepancies. Most studies point out towards a correlation between obesity, insulin resistance, alcohol, smoking, use of illegal drugs and testicular function in pubertal boys. Also, endocrine disruptors and sexually transmitted diseases might contribute to impair reproductive health, but more studies in adolescents are needed.

CONCLUSION

According to currently available evidence, there is an emerging global adverse trend of high-risk and unhealthy behaviors in male adolescents. A significant proportion of young men with unsuspected and undiagnosed andrological disorders engage in behaviors that could impair testicular development and function, with an increased risk for later male infertility and/or hypogonadism during the adult life. Therefore, adolescence should be considered a key time for intervention and prevention of later andrological diseases.

Human papillomavirus vaccination history and diagnosis of cervical intraepithelial neoplasia grade ≥2 severe lesions among a cohort of women who underwent colposcopy in Kaiser Permanente Southern California

BACKGROUND

The risk of a high-grade lesion in women undergoing colposcopy following an abnormal screening result may be different by human papillomavirus vaccination status, because women who are vaccinated are presumably less likely to harbor human papillomavirus types 16 and 18.

OBJECTIVE

This study aimed to evaluate whether the risk of high-grade cervical lesion diagnosed through colposcopy is lower in women with human papillomavirus vaccination than in women without vaccination referred to colposcopy based on equal abnormal screening findings.

STUDY DESIGN

Kaiser Permanente Orange County female patients between ages 21 and 38 years were included following an abnormal screening if they had ≥1 colposcopies between July 2017 and August 2018 and had at least 1 pathology diagnosis from the colposcopy visits. Data on demographic characteristics, clinical and sexual histories, and human papillomavirus vaccination were collected using a colposcopy registry smart form and from electronic medical records. Human papillomavirus genotyping was performed for tissues from confirmed cervical intraepithelial neoplasm grade 2+ diagnoses. A multilevel generalized linear model with a logic function was used to evaluate the association between human papillomavirus vaccination history and the outcome of a cervical intraepithelial neoplasm grade 2+ diagnosis and for human papillomavirus type 16- or 18-positive cervical intraepithelial neoplasm grade 2+ as an alternative outcome, adjusting for screening results and potential confounders.

RESULTS

Of 730 women included in the study, 170 had a histologic diagnosis of cervical intraepithelial neoplasm grade 2+ (23.2%). Moreover, 68 cases (40.0%) were histologically human papillomavirus type 16 and/or 18 positive. Of the 730 women, 311 (43%) were vaccinated for the human papillomavirus before colposcopy. Most women (206 [66.2%]) with human papillomavirus vaccination received the vaccine between the ages 18 and 26 years. A history of human papillomavirus vaccination overall, before sexual debut, before the age of 18 years, or with complete dosing was not associated with lower odds of a cervical intraepithelial neoplasm grade 2+ diagnosis (odds ratio, 1.07 [95% confidence interval, 0.70-1.64]; odds ratio, 1.11 [95% confidence interval, 0.55-2.24]; odds ratio, 0.96 [95% confidence interval, 0.49-1.91]; and odds ratio, 0.84 [95% confidence interval, 0.53-1.35], respectively, in reference to no vaccination). Human papillomavirus vaccination history was not significantly associated with the odds of a human papillomavirus type 16- or 18-positive cervical intraepithelial neoplasm grade 2+ diagnosis (P=.45). Notably, 8 cases (4.8% of all cervical intraepithelial neoplasm grade 2+ cases) showed a human papillomavirus type 16 on a cervical intraepithelial neoplasm grade 2+ histologic polymerase chain reaction analysis despite reported or documented human papillomavirus vaccination before sexual debut, including 2 cases who started vaccination before the age of 13 years.

CONCLUSION

Our study did not support modifying the colposcopy management guidelines for abnormal screening results for women with human papillomavirus vaccination, especially those vaccinated in the catch-up age range. Our findings on the 8 cases of human papillomavirus 16-positive cervical intraepithelial neoplasm grade 2+ vaccination before sexual debut suggested that lowering the recommended age for human papillomavirus vaccination may have additional benefits for preventing human papillomavirus infection that could occur early in life in some women.

Hematopoietic Cell Transplantation and Outcomes Related to Human Papillomavirus Disease in GATA2 Deficiency

GATA2 deficiency is a bone marrow failure syndrome effectively treated with hematopoietic cell transplantation (HCT), which also addresses the predisposition to many infections (prominently mycobacterial). However, many GATA2-deficient persons who come to HCT also have prevalent and refractory human papilloma virus disease (HPVD), which can be a precursor to cancer. We analyzed 75 HCT recipients for the presence of HPVD to identify patient characteristics and transplantation results that influence HPVD outcomes. We assessed the impact of cellular recovery and iatrogenic post-transplantation immunosuppression, as per protocol (PP) or intensified/prolonged (IP) graft-versus-host disease (GVHD) prophylaxis or treatment, on the persistence or resolution of HPVD. Our experience with 75 HCT recipients showed a prevalence of 49% with anogenital HPVD, which was either a contributing or primary factor in the decision to proceed to HCT. Of 24 recipients with sufficient follow-up, 13 had resolution of HPVD, including 8 with IP and 5 with PP. Eleven recipients had persistent HPVD, including 5 with IP and 6 with PP immunosuppression. No plausible cellular recovery group (natural killer cells or T cells) showed a significant difference in HPV outcomes. One recipient died of metastatic squamous cell carcinoma, presumably of anogenital origin, at 33 months post-transplantation after prolonged immunosuppression for chronic GVHD. Individual cases demonstrate the need for continued aggressive monitoring, especially in the context of disease prevalent at transplantation or prior malignancy. HCT proved curative in many cases in which HPVD was refractory and recurrent prior to transplantation, supporting a recommendation that HPVD should be considered an indication rather than contraindication to HCT, but post-transplantation monitoring should be prolonged with a high level of vigilance for new or recurrent HPVD.

Medical approach to children who may have been sexually abused-a narrative review

The medical approach to children who may have been sexually abused involves several issues and aspects that need to be considered. The medical examination of children with suspected sexual abuse is important, but a detailed medical history from the child and the parents or caretakers is always part of every thorough examination. It can take a long time until victims disclose their abuse and physical signs of abuse may no longer be visible at the time of examination. If the physical examination is performed non-acutely, only 2.2% of sexually abused girls show diagnostic signs of injury. An experienced examiner should ideally perform the examination in suspected sexual abuse of children. Knowledge of the current literature is of importance, as the interpretation of findings has changed over the past decades and it can be difficult to differentiate between normal variants, symptoms of other medical problems, and signs of sexual assault. Furthermore, sexual abuse of children presents in various form, not necessarily leading to physical injuries. Since 1992, Adams et al. publish a regularly updated system for the classification of anogenital findings in children with suspected sexual abuse, including a detailed list of physical findings and infections related to sexual abuse. The purpose of this article is to summarize important aspects of the medical approach to children with suspected sexual abuse according to the current literature.

Prevalence of Sexually Transmitted Infections and Risk Factors Among Young People in a Public Health Center in Brazil: A Cross-Sectional Study

INTRODUCTION

Sexually transmitted infections (STI) significantly affect the health of sexually active people, especially young people, and can cause low sexual dysfunction, low self-esteem, infertility, increased transmission of HIV, and death.

METHODS

We reviewed the medical records of a cross-section of users of a public health services center and verified the prevalence of STI and its associated predictors for male and female individuals 13-24 years of age in an interior county of southern Brazil.

RESULTS

The records of 1703 adolescents and young adults, stratified by age (13-18 and 19-24 years, respectively) and sex, admitted between April 1, 2012, and March 31, 2017, were reviewed in this retrospective study. Epidemiological, clinical, and laboratory data of medical records were analyzed using the chi-square test and odds ratio, with confidence interval of 95% by the Stata® 9.0 program. During the study period, a total of 3448 patients were attended to; of these, 1703 (49.39%) were 13-24 years of age, with 86.56% of those 19-24 years having at least 1 STI. The prevalence of STI among men and women, respectively, was 35.40% and 47.67% for condylomata, 8.46% and 7.00% for herpes, 26.35% and 18.80% for syphilis, and 20.06% and 6.27% for urethral discharge syndrome. The risk for STI acquisition was the highest in young adults (odds ratio [OR] 1.55, 95% confidence interval [CI] 1.17-2.06, P = .002), female individuals (OR 1.51, 95% CI 1.14-2.00, P = .004), those with multiple sexual partners (OR 1.62, 95% CI 1.22-2.16, P < .001), and those not using or irregularly using prophylactics (OR 1.62, 95% CI 1.22-2.16, P < .001).

CONCLUSIONS

The findings revealed a significant prevalence of STI among young people in public health service. The predictors associated with STI in these patients were being female, having multiple partners in the last year, and not using or irregularly using prophylactics. These predictors confirm the necessity to implement more aggressive strategies to prevent the occurrence of STI in specific populations with higher disease risk, thereby minimizing costs and damage caused by the infections.

Human Papilloma Virus Vaccination After Pediatric Sexual Abuse Evaluations in the Outpatient Child Sexual Abuse Subspecialty Clinic: A Quality Improvement Project

The nonavalent human papilloma virus (HPV) vaccination prophylactically contributes to the prevention of nine types of HPV-associated oral and genital cancers. HPV vaccination rates remain lower than the national Healthy People 2020 goal of 80%. Victims of pediatric sexual abuse are at a higher risk for acquiring and developing HPV-related outcomes. Current research supports vaccination after sexual abuse as soon as eligible and suggests utilizing multiple types of medical encounters to increase vaccination rates.An institutional-review-board-approved quality improvement project was developed to determine the impact of promoting and providing HPV vaccination during the medical encounter after pediatric sexual abuse in a child protection team (CPT) clinic. Twenty percent of the 111 total clinic patients evaluated in the preintervention period and 21% of the 99 patients evaluated in the postintervention period were HPV vaccine eligible, illustrating a significant opportunity for impact. During the intervention period, 62% of patients who were vaccine eligible and presented for their CPT clinic visit received HPV vaccine. Barriers to vaccination in the outpatient CPT clinic setting included high appointment no-show rates, high social and medical visit complexity, and absence of an appropriate consenting caretaker. Implications for forensic nursing practice are discussed.

High rate of detection of ultrasound signs of prostatitis in patients with HPV-DNA persistence on semen: role of ultrasound in HPV-related male accessory gland infection

BACKGROUND

Papillomavirus (HPV) often occurs in the semen of patients with male accessory gland infection (MAGI). Ultrasound (US) evaluation has been suggested as a promising diagnostic tool for patients with HPV-related MAGI. No data on the spontaneous clearance of HPV-DNA have been reported so far in HPV-related MAGI.

PURPOSE

The primary aim of the study was to assess the percentage of early HPV-DNA spontaneous clearance in patients with prostatitis. The secondary aim was to evaluate the frequency of spontaneous clearance of HPV-DNA among patients with prostatitis associated with the presence or absence of US abnormalities.

METHODS

Patients with inflammatory MAGI and at least one suspicious criterion for HPV infection underwent semen HPV-DNA detection and prostate US. The presence of HPV-DNA was further investigated after a 6-month-long follow-up.

MAIN RESULTS

Eighty patients satisfied the inclusion criteria and were recruited in the study. 69% of patients (55/80) showed HPV-DNA persistence in the semen. Among them, 82% (45/55) was positive for US signs of prostatitis, while they occurred only in 12% (3/25) of those patients with no sign of HPV-DNA persistence (p < 0.001). All patients with persistent high-risk HPV genotype (n = 30) showed at least two US signs of prostatitis. In 73% of patients (22/30), E6 and E7 mRNAs were detected.

CONCLUSION

US signs of prostatitis more frequently occurred in patients with evidence of HPV-DNA persistence on semen, especially in those with high-risk genotypes. This highlights the importance of US in the framework of HPV-related MAGI.

Seroprevalence of HPV serotypes 6, 11, 16 and 18 in unvaccinated children from Mexico City

Data regarding humoral immunity against HPV infection are scarce. Most analyses focus on the identification of viruses on mucous membranes and primarily refer to women of reproductive age. The aim of this work was to estimate the seroprevalence of antibodies against HPV serotypes 6, 11, 16 and 18 among unvaccinated boys living in Mexico City. A cross-sectional study of 257 male students from 48 public primary schools in Mexico City, whose ages fluctuated between 9 and 14 years, was carried out. Immunological status was assessed by applying the competitive Luminex Immunoassay of HPV (cLIA). Among the study population, we initially found that 38.52% (n = 99) of the children tested positive against one or more of the HPV 6, 11, 16 and/or 18 serotypes. The most commonly found serotype was isolated HPV 18 or in combination with other serotypes (22% and 31%, respectively), followed by HPV 6 with frequencies of 4.7% and 11%, respectively; however, lower frequencies were estimated for HPV 16 (2%; 6%) and isolated HPV 11, 4%. If a second set of cut-off points for seropositivity is applied, the overall prevalence for any serotype is reduced to 15.2%. As it appears that a significant sector of the study population has had basal contact with an HPV serotype, we recommend considering the possibility of vaccination against HPV at earlier ages.

Cervical Cancer Screening Programs in Europe: The Transition Towards HPV Vaccination and Population-Based HPV Testing

Cervical cancer is the fourth most frequently occurring cancer in women around the world and can affect them during their reproductive years. Since the development of the Papanicolaou (Pap) test, screening has been essential in identifying cervical cancer at a treatable stage. With the identification of the human papillomavirus (HPV) as the causative agent of essentially all cervical cancer cases, HPV molecular screening tests and HPV vaccines for primary prevention against the virus have been developed. Accordingly, comparative studies were designed to assess the performance of cervical cancer screening methods in order to devise the best screening strategy possible. This review critically assesses the current cervical cancer screening methods as well as the implementation of HPV vaccination in Europe. The most recent European Guidelines and recommendations for organized population-based programs with HPV testing as the primary screening method are also presented. Lastly, the current landscape of cervical cancer screening programs is assessed for both European Union member states and some associated countries, in regard to the transition towards population-based screening programs with primary HPV testing.

Interpretation of Medical Findings in Suspected Child Sexual Abuse: An Update for 2018

Most sexually abused children will not have signs of genital or anal injury, especially when examined nonacutely. A recent study reported that only 2.2% (26 of 1160) of sexually abused girls examined nonacutely had diagnostic physical findings, whereas among those examined acutely, the prevalence of injuries was 21.4% (73 of 340). It is important for health care professionals who examine children who might have been sexually abused to be able to recognize and interpret any physical signs or laboratory results that might be found. In this review we summarize new data and recommendations concerning documentation of medical examinations, testing for sexually transmitted infections, interpretation of lesions caused by human papillomavirus and herpes simplex virus in children, and interpretation of physical examination findings. Updates to a table listing an approach to the interpretation of medical findings is presented, and reasons for changes are discussed.
