OBJECTIVE Large studies describing the profile of high-risk Human papillomavirus (hrHPV) genotypes among women in sub-Saharan Africa are lacking. Here we describe the prevalence and distribution of hrHPV genotypes among HIV-negative women in South Africa, with and without cervical intraepithelial neoplasia (CIN). METHODS We report data on 8,050 HIV-negative women, aged 17-65 years, recruited ...

ObjectivesHuman papillomavirus (HPV) infections are common, especially during women’s reproductive years, with unclear obstetrical impact. This study aimed to identify HPV prevalence at mid-gestation and delivery, type-specific persistence from risk factors for infection persistence.MethodsIn 757 women a Scandinavian prospective mother–child cohort, was analyzed in first-void urine samples deli...

INTRODUCTION Certain genotypes of human papillomavirus (HPV) are linked to cervical abnormalities. HPV DNA and genotype prevalence among women residing in Riyadh, Saudi Arabia is investigated in this hospital-based study. METHODOLOGY Cervical specimens were taken from 519 subjects along with consent and demographic data. DNA was extracted and PCR was performed on all specimens using general p...

Our earlier study demonstrated high prevalence of multiple human papillomavirus (HPV) infection in patients with invasive uterine cervical cancer, including squamous cell carcinoma (SCC). HPV 16 is the most predominant genotype related to SCC of the uterine cervix. The aim of this study was to reveal the biological significance of multiple HPV infection concerning the tumor progression of invas...

BACKGROUND Human papillomavirus (HPV) is the most common viral sexually-transmitted infection. Despite HPV infection is associated with several malignant disorders including penile and anal cancers, little is known about the epidemiology of HPV infection in males, particularly in developing countries. OBJECTIVES The aim of this study was to determine the prevalence of HPV infection and its ge...

Despite the fidelity of host cell polymerases, the human papillomavirus (HPV) displays a degree of genomic polymorphism resulting in distinct genotypes and intra-type variants. The current HPV vaccines target the most prevalent genotypes associated with cervical cancer (HPV16/18) and genital warts (HPV6/11). Although these vaccines confer some measure of cross-protection, a multivalent HPV vacc...

BACKGROUND Human papillomavirus (HPV) is estimated to play an etiologic role in 40-50% of penile cancers worldwide. Estimates of HPV prevalence in U.S. penile cancer cases are limited. METHODS HPV DNA was evaluated in tumor tissue from 79 invasive penile cancer patients diagnosed in 1998-2005 within the catchment areas of seven U.S. cancer registries. HPV was genotyped using PCR-based Linear ...

OBJECTIVE Verrucous carcinoma (VC) is a rare subtype of squamous cell carcinoma, occurring mostly in oral mucosa. To clarify the role of human papillomavirus (HPV) in VC tumorigenesis, we investigated localization and genotypes of HPV and p53 expression in oral VC. METHODS We studied paraffin-embedded specimens of 23 VCs and 10 control non-neoplastic lesions in oral mucosa. To investigate HPV...

Human papillomaviruses (HPV), especially genotypes 16 and 18, are probable effectors of human urogenital malignancies. Although the male urethra is a proposed reservoir of HPV transmission, the association between HPV and squamous cell carcinoma (SCC) of the male urethra has not been studied. The highly sensitive technique of polymerase chain reaction with type-specific HPV 16 and 18 primers an...

This study aimed to describe Human Papilloma Virus (HPV) genotypes and women with cervical intraepithelial neoplasia (CIN) sociodemographic characteristics at the oncology reference centers. A secondary data of 325 records on CIN were analyzed from a cohort database conducted in two public institutions oncological service Northeast Brazil, July 2014 February 2016. The HPV genotype analysis was ...
