Aim: To evaluate the prevalence of coexisting anal human papillomavirus (HPV) infection and concordance of HPV types in women with cervical HPV infection and to investigate the possible predictors for anal HPV infection.
Methods: Study group was composed of women referred with documented cervical HPV infection. All patients had undergone anal HPV DNA testing.
Results: One hundred and six patients presenting with cervical HPV infection were eligible for the study. Overall, 24 and 20 distinct HPV genotypes were detected from cervical and anal specimens, respectively. We observed a considerably high prevalence (51.9 %) of coexisting anal HPV infection in our study group. A majority of the women who were found to have anal HPV infection were infected with oncogenic or probable oncogenic types (64.6 %). There were 20.0 and 58.3 % rate of total and partial concordance between the two sites, respectively. We found that no demographic parameter but history of anal intercourse was related with the risk of anal HPV infection.
Conclusion(s): Women with cervical HPV infection have a considerable risk for coexisting anal HPV infection. Concordance of HPV types infecting the cervix and anal canal is relatively high. There is no strong predictor for anal HPV infection in this population.

Background: Vaccination against HPV is an effective strategy for the prevention of HPV infection and cervical cancer. Nevertheless, the HPV vaccine uptake rate is low among ethnic minorities in Hong Kong. This study sought to assess the feasibility and acceptability of motivational interviewing among South Asian mother-daughter dyads and to preliminarily examine its effects on knowledge of HPV infection and vaccination, health beliefs, intention to have the daughters vaccinated, and initiation and completion of HPV vaccine series.

Human papillomavirus (HPV) infection is the most common sexually transmitted infection in the world. Persistent oncogenic HPV infection has been a leading threat to global health and can lead to serious complications such as cervical cancer. Prevention interventions including vaccination and screening have been proven effective in reducing the risk of HPV-related diseases.

Objective: We attempted to evaluate the immediate high-grade squamous intraepithelial lesion-cervical intraepithelial neoplasia grade 2/3 or worse (HSIL-CIN2+/3+, hereafter referred to as CIN2+/3+) risk of specific human papillomavirus (HPV) genotype and form the precise risk-based triage strategy for atypical squamous cells of undetermined significance (ASC-US) women.
Methods: The clinical data of ASC-US women who underwent HPV genotyping testing and colposcopy were retrospectively reviewed. The distribution and CIN2+/3+ risks of specific HPV genotype were assessed by three approaches.

Importance: As US health care systems shift to human papillomavirus (HPV)-based cervical cancer screening, more patients are receiving positive high-risk non-16/18 genotype HPV results and negative for intraepithelial lesion or malignancy (NILM) cytological findings. Risk-based management guidelines recommend 2 consecutive negative annual results to return to routine screening.
Objective: To quantify patterns of surveillance testing and associated outcomes for patients after an HPV-positive results and NILM cytologic findings.

Verruca vulgaris is a cutaneous infection predominantly caused by human papillomavirus (HPV) type 1, 2, and 4. In immunocompromised individuals infected with human immunodeficiency virus (HIV) infection, HPV leads to a higher prevalence of infections and also has a greater likelihood of being infected with atypical types such as genital-associated HPV in extragenital sites. This case report describes a 48-year-old male patient who presented with skin-colored verrucous papules on the hands and feet, with no evidence of genital lesions.
