Human papillomaviruses of skin and genital lesions
… worldwide are caused by human papillomavirus (HPV) which has been established as the cause of cervical cancer and genital warts (condylomas). Cutaneous HPV types have been weakly associated with non-melanoma skin lesions such as squamous cell carcinoma (SCC) and actinic keratosis (AK). We have …

An in depth study of human papillomavirus diversity in South African women infected with HIV
… for cervical cancer is the Human papillomavirus (HPV). High-risk (carcinogenic) HPV types have been linked with 99% of the incidences of cervical cancer. The most common types identified in almost 70% of cervical cancer cases worldwide are HPV 16 and 18. HPV infection is very common in young …

Characterisation of surfactant protein a as a novel prophylactic means against oncogenic HPV infections
Infection with Human Papillomavirus (HPV) presents a continuous global health challenge due to its incurable nature, particularly impacting low- and middle-income countries (LMIC). Although highly effective prophylactic vaccines targeting the most prevalent HPV types exist, they do not cover all …

The prevalence of different human papillomavirus genotypes in lesions of the uterine cervix as a method in risk assessment of cervical cancer
… persistent infection with Human Papillomavirus (HPV), a sexually transmitted, oncogenic virus. There are more than 100 different HPV genotypes. Of these, studies have largely shown that the high- risk types 16 and 18 account for most cancers. However, with improved screening methods, other …

The role of human papillomavirus (HPV) E6 proteins as a risk factor for oesophageal cancer
… focuses on the role of human papilloma virus (HPV) in the development of OSCC. HPV is a well-known risk factor for cervical cancer resulting in its classification into low- and high-risk HPV types. The role of the different HPV types in OSCC development is not known, but in cervical cancer the …

HPV and p16 in head and neck cancer
… evidence to suggest that human papilloma virus (HPV) may play a causal role in head and neck carcinoma (HNSCC). The aim of this study was to investigate the prevalence of HPV DNA in HNSCC and to determine whether any correlation exists with p16 or survival. An initial pilot study of sixty …

Targeting the human papillomavirus for prevention of cervical cancer
Different types of human papillomavirus (HPV) vary in the extent they cause precursor lesions (CIN) and cancer. There are limited long-term efficacy data on HPV testing in primary screening Among 72 cervical cancers in Mozambique, HPV 16 and 18 were the most frequent HPV types (69% of cases). …

Occurrence, determinants and dynamics of HPV coinfections in a cohort of Montreal university students
Background: Coinfections with multiple types of human papillomavirus (HPV) are a common occurrence among HPV-infected individuals, but the clinical significance and etiology of these infections remain unclear. Though current evidence suggests that women with coinfections have increased HPV exposure …

Human Papillomavirus Prevalence in Asymptomatic Men
Introduction: Human papillomavirus (HPV) is the sexually transmitted etiologic agent of cervical cancer. While HPV infects both men and women, little is known about HPV infection in men. Specifically, knowledge of the prevalence of type-specific HPV infection and the distribution of these …

Investigation of some infectious and genetic factors involved in cervical cancer
… The causal role of Human papillomavirus (HPV) in cervical cancer has been firmly established. However, there have been only a few studies of HPV infection of the cervix in Vietnam, and in cervical cancer in particular. This project was conducted to investigate infectious and genetic …

Human papillomavirus testing and its application in cervical cancer prevention
… persistent infections of human papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN) and cancer, HPVtesting has been proposed for improvement of cervical screening programs, including triaging and follow-up after treatment for CIN. We developed two new methods for HPV-testing with …

DETERMINANTS OF HIGH-RISK HPV SEROPREVALENCE AND DNA PREVALENCE IN MID-ADULT WOMEN
Objective: To estimate high-risk (hr) HPV seroprevalence and DNA prevalence then identify determinants of seropositivity and DNA-positivity in mid-adult women. Methods: We conducted a cross-sectional analysis of 378 females at the University of Washington who were between 30 and 50 years of age and …
