Nongenital Human Papillomavirus Disease

[The detection of the human papilloma virus during hyperplastic processes in the nose, ears and throat]

The objective of the present work was to carry out the virological and histological studies of various neoplastic and hyperplastic processes in the nose, ears, and throat with a view to identifying the presence of human papilloma virus and Epstein-Barr virus. The brush biopsies and remote neoplasms obtained from 18 patients (including 2 children and 16 adults) presenting with various ENT diseases and tumours were available for the virological investigation with the use of the polymerase chain reaction (PCR) and a system MY09-MY11 degenerate primers . The histological study of biopsies and remote neoplasms was carried out by means of conventional light microscopy. The virological and histological studies conducted in parallel confirmed the diagnostic significance of morphological changes at the tissue and cellular levels caused by the human papilloma virus.

Patterns of Sexual Experience Among Urban Latino and African American Ninth Grade Students

This analysis assessed patterns of sexual experience, the order in which behaviors were initiated, and associated factors, among Latino and African American ninth grade students (average age 15.2) who self-administered audio-computer-assisted surveys on netbooks in classes at 10 Los Angeles-area public high schools. Lifetime experiences with vaginal and oral sex were most common (19% and 16%, respectively); fewer reported anal sex (6%). Of the 23% reporting any sex, 91% fell into four categories: 36% reporting both oral and vaginal sex; 23% vaginal only; 18% all three; and 13% oral only. Most sexually experienced students (88%) initiated with vaginal or oral sex (46% vaginal, 33% oral, 9% both same day). No dominant pathway of sexual onset emerged for those reporting all three types of sex. We found no evidence that oral or anal sex substituted for or delayed vaginal sex. Males, those with a current partner, and those reporting multiple partners were more likely than others to report all three sexual behaviors versus vaginal only (odds ratios [ORs] 2.0, 1.5, 3.0; p = .02, .06, < .01, respectively). Although vaginal intercourse dominated their early sexual behavior, one-fifth of sexually experienced students reported anal intercourse, highlighting the need for specific prevention messages surrounding this higher-risk behavior.
