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.

Cell-cycle analysis and apoptosis-associated proteins in cervical lesions of Brazilian women.

Aim: The aim of the present study was to detect the relative expressions of p53, p21(Waf1/Cip1), p27(Kip1) Bcl-2 and cleaved caspase-3 in cervical lesion samples from Brazilian women by immunohistochemistry.

Materials And Methods: A total of 230 cervical biopsies in paraffin-embedded blocks were studied: 43 were invasive squamous cell carcinomas (SCC), 52 carcinomas in situ/cervical intraepithelial neoplasias III (CIN III), 54 cervical intraepithelial neoplasias II (CIN II), 51 cervical intraepithelial neoplasias I (CIN I) and 30 non-neoplastic lesions (NN) with benign cellular changes.

Results: Significant differences were observed in the p53 expression between the different groups: NN and CIN I (p=0.

Malignant peripheral nerve sheath tumor of the uterine corpus: a case report.

Uterine malignant peripheral nerve sheath tumors (MPNST) are rare and have been reported in the cervix. We describe a case of MPNST of the uterine corpus, and discuss its differential diagnosis.

Immunohistochemical expression of p16(INK4A) in normal uterine cervix, nonneoplastic epithelial lesions, and low-grade squamous intraepithelial lesions.

Objectives: In this study, the authors analyzed the immunoexpression of p16 in high-risk human papillomavirus DNA-negative normal and nonneoplastic cervical epithelia, in low-grade cervical intraepithelial neoplasia (CIN), high-grade CIN, and squamous cell carcinoma.

Materials And Methods: A retrospective study, in which 58 normal cervical hysterectomy samples, 56 nonneoplastic cervical biopsies, 88 CIN 1, 33 CIN 2, 32 CIN 3, and 47 invasive squamous cell carcinoma biopsies, were evaluated for p16 immunoexpression. Human papillomavirus tests were also performed.
