Prevalence of DNA-HPV in male sexual partners of HPV-infected women and concordance of viral types in infected couples.

Investigation of HPV infection in men remains important due to its association with genital warts and anorectal cancer, as well as to the role men play in HPV transmission to their female sexual partners. Asymptomatic men (n = 43), whose sexual partners had presented cervical HPV infection, were enrolled in this study. Among the 43 men, 23 had their female partner included and tested for HPV-DNA, totaling 23 couples.

Minichromosome maintenance 7 protein is a reliable biological marker for human cervical progressive disease.

Objective: This study focused on comparing the expression levels of p16, Ki-67, and minichromosome maintenance 7 (MCM7) protein in normal and affected cervical epithelium to ascertain the biological significance of these markers in detecting progressive cervical disease.

Methods: A quantitative and based on-scanning-microscopy analysis of the three markers expression was performed in normal and cervical intraepithelial neoplasia (CIN) I, II, and III tissues. p16 area as well as p16, Ki-67, and MCM7 positive cells or nuclei were evaluated according to their distribution and extent through the cervical epithelium.

Detection of human papillomavirus infection in penile samples through liquid-based cytology and polymerase chain reaction.

Background: The human papillomavirus (HPV) is strongly related to cervical cancer and its precursor lesions. However, unlike in the case of women, there are limited data regarding HPV infection in men. Analysis of male HPV infection is frequently hindered by the lack of consistency in collection methods, sample adequacy, and low sensitivity of cytologic analysis.

Molecular detection of HPV 16 and 18 in cervical samples of patients from Belo Horizonte, Minas Gerais, Brazil.

Purpose: The aim of this study was to investigate the frequency of HPV infection and the types 16 and 18 in cervical samples from patients attended at two public health services of the city of Belo Horizonte, MG.

Methods: Cervical samples from 174 patients were collected for cytopathological and molecular tests. HPV infection was searched by PCR utilizing MY09 and MY11 primers or HPV 16 and HPV 18 specific primers.

Molecular detection of Chlamydia trachomatis and HPV infections in cervical samples with normal and abnormal cytopathological findings.

It has been suggested that Chlamydia trachomatis (CT) and human papillomaviruses (HPV) co-infection could contribute to development of intraepithelial lesions. In this study, HPV and CT-DNA were investigated in 250 cervicovaginal samples of patients from Minas Gerais, Brazil. The cytological analysis revealed that 70% of samples (175) were negative, 5.

[Ulcerative esophagitis associated with the use of alendronate sodium: histopathological and endoscopic features].

Background: Drug-induced or "pill-induced" esophagitis may be secondary to the prolonged contact of the drug with the esophageal mucosa or secondary to the drug ability to alter the local conditions. The alendronate sodium, a bone resorption inhibitor used in the treatment and prevention of osteoporosis, has been cited, recently, as one of the causes of adverse upper gastrointestinal tract injury.

Aim: To describe the clinical, endoscopic and histopathological features of patients with ulcerative esophagitis associated with alendronate sodium.
