Efficacy of Fractional Laser on Steroid Receptors in GSM Patients.

Background: To compare the efficacy of CO fractional laser with that of topical estriol for treating genitourinary syndrome of menopause and to investigate the relationship between epithelial thickness and vaginal atrophy.

Methods: Twenty-five menopausal women were randomized to receive either laser or estrogen treatment. Vaginal biopsies before and after treatment were compared to assess the amount and distribution of estrogen and progesterone receptors.

Chlamydia trachomatis, Neisseria gonorrhoeae and human papillomavirus infections of lower genital tract of Indigenous women from Xingu Indigenous Park.

Introduction: Xingu Indigenous Park (XIP) currently protects 16 ethnic Indigenous groups and is located in the central area of Brazil. XIP is the first and the largest Indigenous land to be recognized in the country. Community access is limited and restricted for the non-Indigenous population, and the Indigenous women are constantly dealing with shortages of medical care.

Effects of oxytocin versus promestriene on genitourinary syndrome: a pilot, prospective, randomized, double-blind study.

Objectives: In this pilot, prospective, randomized, double-blind study, the authors compared the efficacy of oxytocin with promestriene in improving vaginal atrophy of Genitourinary Syndrome of Menopause (GSM).

Methods: A total of 51 postmenopausal women with symptoms of GSM were evaluated. They were randomized into two groups: oxytocin (25 patients) and promestriene (26 patients) and were evaluated before and after 90 days of treatment; the evaluation was based on the domains of the Female Sexual Function Index (FSFI) (lubrication, satisfaction, and pain during sexual intercourse), clinical visual examination, and vaginal wall thickness.

Comparison of topical fractional CO2 laser and vaginal estrogen for the treatment of genitourinary syndrome in postmenopausal women: a randomized controlled trial.

Objective: To compare the efficacy of fractional CO2 laser therapy with topical estrogen therapy for the treatment of postmenopausal genitourinary syndrome of menopause.

Methods: We conducted a randomized controlled clinical trial involving 25 postmenopausal women. Participants were aged between 50 and 65 years with at least 1 year of amenorrhea and follicle-stimulating hormone levels of >40 IU/L.

Expression of CK7 and CDKN2 in Cervical Intraepithelial Neoplasia and Correlation with Clinical Outcome.

Aim: To evaluate cyclin-dependent kinase inhibitor 2A (CDKN2A) and cytokeratin 7 (CK7) expression in cervical intraepithelial neoplasia (CIN) formalin-fixed samples.

Materials And Methods: Staining with antibody clones G175-405 for CDKN2A and OV-TL 12/30 for CK7 were evaluated and the detection of protein expressions were compared in 147 patients with CIN.

Results: Clinical follow-up of patients with CIN1 and CIN2 showed that most patients had a favorable outcome.

Dual p16 and Ki-67 Expression in Liquid-Based Cervical Cytological Samples Compared to Pap Cytology Findings, Biopsies, and HPV Testing in Cervical Cancer Screening: A Diagnostic Accuracy Study.

Objective: Our objective was to verify the sensitivity and specificity of dual immunocytochemistry staining for p16 and Ki-67 in liquid-based samples (the "dual" assay) for cervical lesion screening, compared to biopsy findings and human papillomavirus (HPV) DNA molecular detection.

Study Design: Sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values for the "dual immunocytochemistry assay" were calculated and compared to histopathological results and to high-risk HPV DNA detection in adult women or teenagers submitted to cervical cancer screening.

Results: A total of 151 women were included.

Anal human papillomavirus (HPV) prevalences and factors associated with abnormal anal cytology in HIV-infected women in an urban cohort from Rio de Janeiro, Brazil.

Identifying factors, including human papillomavirus (HPV) genotypes, associated with abnormal anal cytology in HIV-infected women have implications for anal squamous cell cancer (SCC) prevention in HIV-infected women. Anal and cervical samples were collected for cytology, and tested for high-(HR-HPV) and low-risk HPV (LR-HPV) genotypes in a cross-sectional analysis of the IPEC Women's HIV Cohort (Rio de Janeiro, Brazil). Multivariate log-binomial regression models estimated prevalence ratios for factors associated with abnormal anal cytology [≥ atypical squamous cells of undetermined significance, (ASC-US)].

Vascular endothelial growth factor and KIT expression in relation with microvascular density and tumor grade in supratentorial astrocytic tumors.

Purpose: To evaluate the relationship between microvascular density and the expression of vascular endothelial growth factor (VEGF) and KIT as possible markers of angiogenic stimulus in astrocytic tumors and correlate it with histopathological grading.

Methods: We enrolled 99 surgical specimens of supratentorial astrocytic tumors for analysis of VEGF and KIT and subsequent correlation with MVD and grading.

Results: KIT and VEGF expression correlated with microvascular density (p<0.

Vaginoplasty with oxidized cellulose: anatomical, functional and histological evaluation.

Objective: To present and evaluate the histological, anatomical and functional results of the McIndoe procedure, as modified by the application of oxidized cellulose (Surgicel™) in women with vaginal agenesis.

Study Design: Eleven patients with vaginal agenesis underwent vaginoplasty using a mould that had been wrapped with oxidized cellulose. The surgeries were performed between January 2009 and January 2010.

Hepatocellular carcinoma in association with bile duct hamartomas: report on 2 cases and review of the literature.

Biliary hamartomas are hepatic lesions related to defects in the ductal plate and are part of the spectrum of adult polycystic disease. Microscopically, the lesions are small and consist of irregular bile ducts amidst a fibrous stroma. There are reports on the malignant transformation of biliary hamartomas, particularly on cholangiocarcinoma.

Myoid hamartomas of the breast: report of 3 cases and review of the literature.

Hamartomas were first described by Albrecht in 1904, who defined them as tumor-like malformations in which there was abnormal blending of the normal components of an organ. The myoid hamartoma is a rare benign lesion of the breast and has an uncertain origin, possibly in the walls of the blood vessels, muscularis mammillae of the areolae, and mainly in myoepithelium. We report 3 cases of myoid hamartomas of the breast, with the clinical, radiologic, and histopathological findings, and review the literature.
