Incidence of Cervical Human Papillomavirus and Cervical Intraepithelial Neoplasia in Women with Positive and Negative HIV Status.

Objectives To evaluate the incidence and factors associated with cervical intraepithelial neoplasia (CIN) and cervical infection by human papillomavirus (HPV) among HIV-positive and HIV-negative women. Methods A cohort of 103 HIV positive and 113 HIV negative women were monitored between October 2008 and February 2012, for at least one year. Procedures included cervical cytology, DNA/HPV detection by polymerase chain reaction, colposcopy with biopsy if necessary, followed by an interview for exposure characteristics data.

Prevalence and risk factors for cervical intraepithelial neoplasia among HIV-infected women.

Objectives: To evaluate the prevalence and the risk factors for cervical intraepithelial neoplasia (CIN) among HIV-infected women.

Methods: Cross-sectional study of 494 HIV-infected women in Brazil, between 1998 and 2008. Gynecologic exam was performed, and samples were collected for cervical cytology and for HPV DNA detection.

Kinetics of hepatitis C virus load and hemodialysis: is there any influence of the reuse of dialysis membrane on HCV viremia?

Background: Patients with chronic kidney disease (CKD) on regular hemodialysis are at increased risk of acquiring hepatitis C virus (HCV). Although controversial, a distinct dynamic of the HCV load has been reported in this group - a lower HCV viremia compared to non-uremic patients. The reasons for this remain unclear, but the host immune response related to the hemodialysis procedure and the reuse of dialysis membranes are the most investigated factors.

Prevalence and multiplicity of HPV in HIV women in Minas Gerais, Brazil.

Objective: To detect the frequency and subtypes of HPV in the uterine cervix of HIV-infected women.

Methods: Sample consisted of 288 HIV-infected women, recruited from the public health system of five cities of Minas Gerais, Brazil. Women were seen from August 2003 to August 2008.

[Discrepancy of celiac disease presentation in monozygotic twins].

Context: The celiac disease is an immune-mediated enteropathy caused by a permanent sensitivity to gluten in genetically susceptible individuals. Despite the genetic characteristic of the disease, studies show discrepancy of 30% in its presentation in monozygotic twins.

Objective: To present two pairs of monozygotic confirmed by genetic study and discordant for presentation of celiac disease.

Comparison of HPV genotyping by type-specific PCR and sequencing.

Human papillomavirus (HPV) infection is the most common sexually transmitted disease worldwide and there is a strong link between certain high-risk viral types and cervical carcinogenesis. Although there are several typing methods, it is still unclear which test is the best. This study compared the effectiveness of type-specific PCR (TS-PCR) and sequencing, with a focus on their clinical application.

Populational genetic data for 15 STR markers in the Brazilian population of Minas Gerais.

Fifteen short tandem repeats (STR) markers were analyzed (TPOX, D2S1338, D3S1358, FGA, D5S818, CSF1PO, D7S820, D8S1179, TH01, vWA, D13S317, D16S539, D18S51, D19S433, and D21S11) in unrelated individuals undergoing paternity studies from Minas Gerais state, Brazil. Allele frequencies and statistical parameters for the 15 loci were calculated.

[High prevalence of genotype 1 in individuals with hepatitis C in Belo Horizonte, MG].

The hepatitis C virus is characterized by significant genetic heterogeneity. It is currently classified into six main genotypes and several subtypes. Determining the genotype of the virus is important in clinical practice for guiding the treatment for individuals with chronic hepatitis C.
