BACKGROUND HPV is the most prevalent sexually transmitted infection and its effect in cancer induction is well documented. HPV infections are mostly asymptomatic, but it is unclear whether HPV infections can result in alterations of reproductive health. OBJECTIVE To determine the relationship between human papillomavirus infections and reproductive health in both men and women. METHODS A sy...

Human papillomavirus (HPV) is classified into high-risk HPV (HR-HPV) and (LR-HPV) according to their oncogenic potential. These viruses can be found in the cervix, vagina, vulva, anus ENT sphere. infections lead benign or malignant tumors which we could find both LR-HPV HR-HPV genotypes. The objective of this study was investigate genotypes archived tissue samples derived from ear, nose, throat...

UNLABELLED Background Men and women with HIV infection are at increased risk of developing cancers associated with human papillomavirus (HPV). The two licensed prophylactic HPV vaccines protect against de novo infection with HPV-16 and HPV-18, which cause the majority of HPV-associated cancers. Currently, no vaccine efficacy data are available for persons with HIV infection. Nevertheless, some ...

Previous studies have shown that risk factors for oncogenic (high-risk) and nononcogenic (low-risk) human papillomavirus (HPV) infection differ. To determine the risk factors for oncogenic and nononcogenic HPV infection in women residing along the United States-Mexico border, a cross-sectional study of type-specific HPV prevalence was conducted. Women (N=2246) ages 15-79 years, living in commun...

Human papillomaviruses (HPVs) have been recognized as the main etiologic agent of cervical cancer and other anogenital neoplasms, and a leading cause of death from cancer worldwide. In the last twenty years, extensive research has contributed to document the molecular mechanisms of virus persistence and malignant transformation, confirming a direct role of viral proteins in these processes. A c...

Human papillomavirus (HPV) infection is the cause of squamous cell carcinoma of the uterine cervix. This causative relationship has provided the rationale and incentive for development of a prophylactic vaccine. Such a vaccine, if found to be effective, could reduce the need for cervical cancer screening and have a profound effect on the incidence of cervical and other anogenital cancers. This ...

Infection by certain human papillomavirus types is regarded as the major risk factor in the development of cervical cancer, one of the most common cancers of women worldwide. Analysis of the immunogenic and structural features of papillomavirus virions has been hampered by the inability to efficiently propagate the viruses in cultured cells. For instance, it has not been established whether the...

HPV transmission dynamics have rarely been studied in the general population, especially in China. We followed the genital HPV infection status of both partners in 874 couples aged 25-65 years from rural China for up to 7 bi-annual visits during 2009-2013. The positive HPV concordance and transmission rate for partners in a couple were evaluated and relevant risk factors were assessed. The conc...

We evaluated the risk factors associated with oral human papillomavirus (HPV) infection and oral lesions in 161 human immunodeficiency virus (HIV)-positive patients and 128 HIV-negative patients presenting for oral examination at 2 urban healthcare centers. Patients were interviewed on risk factors and provided oral-rinse samples for HPV DNA typing by polymerase chain reaction. Statistical asso...

Background. Smoking may increase the risk of cervical cancer, a disease that is related to human papillomavirus (HPV) infection. However, the effects of smoking on the natural history of HPV are poorly understood, especially in women coinfected with human immunodeficiency virus (HIV).Methods. HIV-infected (n=1797) and HIV-uninfected (n=496) women were assessed every 6 months for type-specific H...
