Growing evidence suggests a role for human papillomavirus (HPV) in oral cancer; however its involvement is still controversial. This study evaluates the frequency of HPV DNA in a variety of oral lesions in patients from Argentina. A total of 77 oral tissue samples from 66 patients were selected (cases); the clinical-histopathological diagnoses corresponded(More)
The metastasis status of pelvic lymph nodes (PLNs) seems to be a predictive factor of survival. It was suggested that the presence of HPV DNA and other biological markers in PLN may indicate a sub clinical early metastasis. The aim was to describe the prevalence and distribution patterns of HPV DNA and H-ras mutations in intra operatively obtained cervical(More)
In more than 10 Spanish dairy cows, a bovine herpesvirus 4 (BHV4) associated postpartum metritis was confirmed by virus isolation, BHV4-glycoprotein B (gB) PCR and/or serology. In this study, 12 cows with, and, at the time of sampling, 3 cows without clinical signs of acute postpartum metritis from one large dairy herd in Spain were examined for bacterial(More)
Genital infection with human papillomavirus (HPV) is decisive in the causation of cervical cancer. In order to evaluate the epidemiology of HPV infection in Ushuaia, Province of Tierra del Fuego, Argentina, 132 endocervical cytobrushes from preneoplastic and neoplastic cases and controls were studied. Detection and typing of the viral genome was performed(More)
UNLABELLED Human papillomavirus type 6 (HPV6) is the major etiological agent of anogenital warts and laryngeal papillomas and has been included in both the quadrivalent and nonavalent prophylactic HPV vaccines. This study investigated the global genomic diversity of HPV6, using 724 isolates and 190 complete genomes from six continents, and the association(More)
OBJECTIVES Due to the scarce data on the prevalence of sexually transmitted infections (STIs) among male-to-female trans-sex workers (TSW) and male sex workers (MSW) in Argentina, the present study aimed to estimate the incidence of human immunodeficiency virus (HIV), and the prevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and Treponema(More)
BACKGROUND Reports on the prevalence and genotypes of HPV among trans (male to female transvestites, transsexuals or transgender) sex workers (TSW) are scarce in the literature. OBJECTIVES The aim of the study was to determine the infecting HPV genotypes among TSW in Argentina. STUDY DESIGN 119 TSW were recruited. Anal cells were self collected with a(More)
Perimenopause is an imprecise period in woman over 40 years of age, which comprises the time between the moment that the first changes in the menstrual cycle appear and the year following the definitive cessation of the menses. Besides irregular bleeding, many women also complain of hot flashes and other characteristic symptoms of postmenopause. Moreover,(More)
OBJECTIVES To investigate associations between HLA-DRB1 and HLA-DQB1 polymorphisms with low- and high-grade cervical lesions in Argentine population and the role human papillomavirus status in these associations. MATERIALS AND METHODS Cervical biopsies and peripheral blood samples were taken from 32 patients with cervical intraepithelial neoplasia grade 1(More)
A genital infection with human papillomavirus (HPV) of a high risk type is necessary for the development of cervical carcinoma. HPV viral distribution among diverse world populations is not homogeneous, viral reservoirs having been detected in particular regions that can interact when humans engage in active contacts. Such viral dynamics alters the(More)
