13. Prevalência de infecção oral e orofaríngea pelo HPV em estudos na população brasileira: revisão sistemática
RESUMO Introdução: O papilomavírus humano (HPV) tem sido associado ao carcinoma de células escamosas (CCE) de cabeça e pescoço. No entanto, não existem evidências conclusivas sobre a prevalência de infecção oral ou faríngea pelo HPV na população brasileira. Objetivo: Determinar a taxa de infecção pelo HPV na população brasileira. Método

14. Epidemiology of oral HPV in the oral mucosa in women without signs of oral disease from Yucatan, Mexico
High-risk human papillomaviruses (HR-HPV) are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investi

15. Safety, tolerability and side effects of human papillomavirus vaccines: a systematic quantitative review
Recently, many studies have evaluated HPV vaccine safety and adverse effects. Two vaccine shave been recently evaluated in randomized controlled trials: the bivalent vaccine for HPV 16 and 18 (Cervarix, GlaxoSmithKline Biologicals, Rixensart, Belgium) and the quadrivalent vaccine for HPV 6, 11, 16, and 18 (Gardasil, Merck and Co., Inc., Whitehouse Station, N

16. Prevalence of high-risk human papillomavirus by cobas 4800 HPV test in urban Peru
Background: Molecular tests allow the detection of high-risk human papillomavirus in cervical samples, playing an important role in the prevention of cervical cancer. Objectives: We performed a study to determine the prevalence of HPV 16, HPV 18 and other high-risk human papillomavirus (pool 12 genotypes) in Peruvian females from diverse urban areas using

17. High incidence of oncogenic HPV genotypes found in women from Southern Brazil
Oncogenic HPV genotypes are strongly associated with premalignant and malignant cervical lesion. The purpose was to determine human papillomavirus (HPV) prevalence and genotypes, and to estimate cervical cancer risk factor associations. Cervical samples were obtained from 251 women seeking gynecological care at the Pelotas School of Medicine Clinic. This is

18. Association between human papillomavirus (HPV) DNA and micronuclei in normal cervical cytology
The aim of the present study was to investigate the association between HPV-DNA and micronucleus (MN) frequency in women with normal cervical cytology. A total of 158 normal cervical smears were analyzed cytologically. The HPV genome was amplified using the GP5+/bioGP6+ consensus primers. HPV-DNA of high-risk types 16, 18, 31, 33, 39, 45 and 59 were also inv

19. HPV infection, risk factors and viral load among Mexican male college students
Objectives: To determine the prevalence of HPV and the risky sexual behaviors associated to it in a sample of male college students, taking into account genotype and viral load. Methods: From 2002 to 2003, male students from the Autonomous University of Morelos State completed a questionnaire and provided self-collected genital samples to detect and quant

20. Genital prevalence of HPV types and co-infection in men
Introduction: HPV infection is a highly prevalent sexually transmitted disease and there is evidence of the relationship of HPV infection and the development of genital warts, penile intraepitelial neoplasia, invasive penile carcinoma and cervical cancer. However, there is sparse data regarding the prevalence of HPV types and co-infection of different HPV t

21. TT virus in peripheral blood cells from patients with human papillomavirus (HPV): investigating association with cervical carcinoma
Torque Teno Virus (TTV) presence was investigated in peripheral blood of 117 brazilian women by nested polymerase chain reaction. TTV DNA was observed in 18.6% of healthy donors and in 24.32% Human Papillomavirus (HPV) patients. TTV presence was also investigated in the HPV positive group for comparison between the cervical cancer and noncancerous patients.

22. Human papillomavirus types 16 and 18 and the prognosis of patients with stage I cervical cancer
OBJECTIVE: This study sought to evaluate the prevalence of human papillomavirus (HPV) types 16 and 18 in women with clinical stage IB cervical cancer treated by radical hysterectomy with pelvic lymphadenectomy as well as to establish a correlation between HPV type and cancer prognosis. METHODS: A single-center cohort study was conducted with 86 patients w

23. Human papillomavirus infection among sexual partners attending a Sexually Transmitted Disease Clinic in Rio de Janeiro, Brazil
Cervical cancer is a major source of illness and death among women worldwide and genital infection with oncogenic human papillomavirus (HPV) its principal cause. There is evidence of the influence of the male factor in the development of cervical neoplasia. Nevertheless, the pathogenic processes of HPV in men are still poorly understood. It has been observed

24. Interação de oncoproteínas virais E6 e E7 de HPV16/18 com alvos celulares potenciais para o desenvolvimento de estratégias terapêuticas. / Interaction of E6 and E7 viral oncoproteins of HPV16/18 with potential cellular targets to the development of therapeutic strategies.
O potencial oncogênico do papilomavírus humano (HPV) baseia-se na capacidade das oncoproteínas virais E6 e E7 alterarem o ciclo celular, levando à imortalização e malignidade das células. O importante papel das oncoproteínas na progressão tumoral e na interação com inúmeros alvos celulares tem relevância em estudos para o desenvolvimento de vaci
