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)
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)
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)
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)
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)
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)
The mortality rate for cervical cancer (CC) in Northern Argentina is three times higher than the average for the country (7.8 deaths/100,000 women). We determined the prevalence and genotype distribution of human papillomavirus (HPV) in 227 sexually active women of the native Pilagá community in Formosa, Argentina. We also conducted an HPV-16 variant(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)
Data relating to Rickettsia typhi infection in Spain are scarce. A serological survey of 383 serum samples (184 males, 199 females) from the general population and 120 sera from sheep were studied by immunofluorescence assay (IFA). The human serum samples were collected from the general population of Palencia and Burgos provinces, and sheep serum samples(More)
OBJECTIVES To compare the prevalence of prothrombin G20210A in patients with objectively confirmed cerebral vein or cortical vein thrombosis against healthy controls, and evaluate geographical variations. DESIGN Systematic review and meta-analysis of case control studies. METHODS We conducted a systematic review of electronic databases including MEDLINE(More)
