RAP1-GTPase immunostaining is altered in human precancerous and cancerous cervical lesions.

This study investigated RAP1 immunostaining variation in different cell types during CC progression. Paraffin-embedded cervical tissues from 101 patients were categorized into control, pre-neoplastic and neoplastic groups. RAP1 immunolocalization, HPV detection and genotyping were performed.

Prevalence of DNA-HPV in male sexual partners of HPV-infected women and concordance of viral types in infected couples.

Investigation of HPV infection in men remains important due to its association with genital warts and anorectal cancer, as well as to the role men play in HPV transmission to their female sexual partners. Asymptomatic men (n = 43), whose sexual partners had presented cervical HPV infection, were enrolled in this study. Among the 43 men, 23 had their female partner included and tested for HPV-DNA, totaling 23 couples.

Detection of human papillomavirus infection in penile samples through liquid-based cytology and polymerase chain reaction.

Background: The human papillomavirus (HPV) is strongly related to cervical cancer and its precursor lesions. However, unlike in the case of women, there are limited data regarding HPV infection in men. Analysis of male HPV infection is frequently hindered by the lack of consistency in collection methods, sample adequacy, and low sensitivity of cytologic analysis.
