The high-risk human papillomavirus (HR-HPV) has been known as the most important carcinogen in uterine cervical carcinoma. However, there is limited evidence of malignant potential these concurrent multiple infections. This study included women who had undergone conization. They underwent an HPV test by swab within 12 months before surgery. were divided into two groups: one with a single infect...

BACKGROUND Previous findings regarding risk factors for human papillomavirus (HPV) persistence, other than viral determinants, identified from prospective cohort studies have been inconsistent in part because study designs have differed with respect to differing HPV detection methods and varying lengths of follow-up time. Therefore, the objectives of this study were to continue the search for e...

We examined the prevalence of human papillomavirus (HPV) infection in a sample of Brazilian women presenting normal cervical cytology. Possible interactions between patient characteristics and HPV infection were analyzed in order to provide background data to improve cervical cancer screening and prophylaxis. Cervical samples of 399 women, received for routine evaluation in the Health Depa...

BACKGROUND Human papillomavirus (HPV) infections cause disease in men and women, and male-to-female HPV transmission influences the risk of cancer in females. The purpose of the present study was to describe the overall and age-specific incidence and clearance of HPV infections in men. METHODS In a prospective cohort study of 290 men aged 18-44 years, participants were examined at baseline an...

Introduction: Human papillomavirus (HPV), belonging to the Papovavirida family, is the most prevalent sexually transmitted disease (STD) agent worldwide. In Brazil, it is estimated that there are 3-6 million people infected with HPV. Aim: The aim of this study was to evaluate the knowledge of young male students about penis cancer related to HPV infection. Methods: This exploratory and quantita...

BACKGROUND The implementation of highly active antiretroviral therapy (HAART) among HIV-positive patients results in immune reconstitution, slower progression of HIV disease, and a decrease in the occurrence of opportunistic infections. However, the impact of HAART on cervical human papillomavirus (HPV) infection, clearance, and persistence in high-risk adolescents remains controversial. METH...

BACKGROUND High rates of persistence of human papillomavirus (HPV) infection have been reported for adult women with human immunodeficiency virus (HIV) infection. Although most women are first infected with HPV during adolescence, persistence of specific HPV types has not been carefully examined among HIV-infected adolescents. The objective of this study was to examine the rates of and risk fac...

Lung cancer is the leading cause of cancer deaths among Taiwanese women. Human papillomavirus (HPV) has been detected in lung cancer tissues. The aim of this study was to investigate the association between HPV infection and lung cancer among the Taiwanese women. The analytical data were collected from the longitudinal health insurance databases (LHID 2005 and 2010) of the National Health Insur...

Papillomaviruses infect epithelial cells, and depend on epithelial differentiation for completion of their life cycle. The expression of viral gene products is closely regulated as the infected basal cell migrates towards the epithelial surface. Expression of E6 and E7 in the lower epithelial layers drives cells into S-phase, which creates an environment that is conducive for viral genome repli...

Background & Objective: Malignant breast tumors, which are one of the most important deadly cancers in women, like many other cancers, are proposed to be related to viruses etiologically. Proper management of breast carcinoma necessitates an identification of the etiological factors. Human Papillomavirus is considered to have an etiological role in breast carcinoma. We...
