In order to determine the prevalence of human papillomavirus (HPV) infection in sexually active female population in Messina, we tested cervical scrapes of women referred to university clinics for routine gynaecologic care. Between March and December 2008, a total of 680 cervical samples of 598 patients (573 Italian from province of Messina and 25 resident aliens) were examined consecutively fr...

Data from the National Health and Nutrition Examination Survey, 2009-2010, indicated that the prevalence of human papillomavirus (HPV) infection among women was 42.7% in the cervix and 3.8% in the oral cavity. The prevalence of oral HPV infection was 5-fold higher among women with than among those without cervical HPV infection (7.0% vs 1.4%; prevalence ratio, 4.9 [95% confidence interval, 2.7-...

BACKGROUND Besides an established role for certain human papillomavirus (HPV) genotypes in the etiology of cervical cancer, little is known about the influence of multiple-type HPV infections on cervical lesion risk. We studied the association between multiple HPV types and cervical lesions among 2,462 Brazilian women participating in the Ludwig-McGill study group investigation of the natural h...

Little information is available regarding distribution of HPV types in different histological subtypes of adenocarcinoma (AC). Thus, in this study we examined the frequency of high-risk (hr) HPV types in AC, adenocarcinoma in situ (AIS) and adenosquamous carcinoma (ADSQ). A total of 102 cases of primary cervical adenocarcinoma (26 AIS and 76 invasive AC) obtained from pathology files from 1995-...

Subclinical oral human papillomavirus (HPV) infection that persists for decades is likely to precede an HPV-driven squamous cell carcinoma of the head and neck, but little is known about the natural history of oral HPV. We systematically reviewed and abstracted data from nine manuscripts that examined human immunodeficiency virus-negative and cancer-free subjects for oral HPV DNA to determine t...

Sinonasal cancers represent a highly heterogeneous group of head and neck cancers, for which etiological prognostic significance high-risk human papillomavirus (HPV) infections has not yet been conclusively established. We investigated the presence transcriptionally-active HPV in series 34 sinonasal squamous cell cancer (SNSCC) cases evaluated effect on overall survival. In addition, we perform...

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...

OBJECTIVES To estimate the frequency of human papillomavirus (HPV) infection and the genotype distribution of HPV among women with a Pap smear showing atypical squamous cells of undetermined significance (ASC-US) attending the Program for the Detection and Control of Cervical Cancer in Bogotá, Colombia. STUDY DESIGN Cervical samples from 200 women with an ASC-US Pap smear were analyzed for th...

Human papillomavirus (HPV) type-specific distribution was evaluated in genital samples collected from 654 women from the South of Italy undergoing voluntary screening and correlated with cyto-histological abnormalities. HPV DNA was detected in 45.9% of the samples, 41.7% of which had multiple infection and 89.0% had high-risk HPV infection. The prevalence of HPV infection and the rate of multip...

BACKGROUND Anal cancer has become one of the most common non-AIDS-defined tumors among Human Immunodeficiency Virus-positive (HIV+) individuals, and a rise in its incidence among HIV+ Men who have Sex with Men (MSM) has been shown, despite the introduction of Highly Active Anti-Retroviral Therapy (HAART). Human Papillomavirus (HPV) infections are highly prevalent among HIV+ MSM and recent studi...
