BACKGROUND Changes in host tumor genome DNA methylation patterns are among the molecular alterations associated with HPV-related carcinogenesis. However, there is little known about the epigenetic changes associated specifically with the development of anal squamous cell cancer (SCC). We sought to characterize broad methylation profiles across the spectrum of anal squamous neoplasia. METHODOL...

The American Society for Colposcopy and Cervical Pathology sponsored a consensus conference in 2001 to develop evidence-based guidelines for women with histologic abnormalities of the cervix. The options for management of cervical intraepithelial neoplasia 1, 2, and 3 are ranked according to the strength of the recommendation and the quality of the evidence. Follow-up with repeat cytology at si...

Smad4 is a central mediator for TGFbeta signals, which play important functions in many biological processes. To study the role of Smad4 in mammary gland development and neoplasia, we disrupted this gene in mammary epithelium using a Cre-loxP approach. Smad4 is expressed in the mammary gland throughout development; however, its inactivation did not cause abnormal development of the gland during...

OBJECTIVE This study aimed to determine the accuracy of visual inspection with acetic acid (VIA) versus conventional Pap smear as a screening tool for cervical intraepithelial neoplasia/cancer among human immunodeficiency virus (HIV)-infected women. MATERIALS AND METHODS A total of 150 HIV-infected women attending the Moi Teaching and Referral Hospital HIV clinic in Eldoret underwent conventi...

Case Description- A 25-year old, mare, Arab horse presented to department of surgery of veterinary hospital of Shahid Chamran university of Ahvaz with the signs of breathing disorder, snoring, localized infections of the nose in the right nostril. Clinical Findings- Physical examination revealed a mass in the nasal vestibule which attached to the septum and caused partial obstruction of the nas...

Background & Objective: This study aimed to examine the extent which postcoital bleeding (PCB) can be a predictive factor for cervical cancer. Materials Methods: In this observational we selected and evaluated 280 females with PCB referred Kowsar Hospital of Qazvin, Iran from 2017 2019. Results: Among 189 patients diagnosed as normal in their Pap smear results, one patient had cancer her b...

Cervical intraepithelial neoplasia grade 3 (CIN 3) is the best proxy in research and screening for invasive cancer risk. Yet the timing of CIN 3 development is uncertain because of measurement errors integral to its diagnosis. We were interested in estimating the proportions of prevalent vs incident CIN 3 within 2 years of finding a minor cytologic abnormality. We estimate that only 17 (2.8%) o...

Our study was carried out on a total number of 158 patients, with a mean age of 32, all tested and identified cytologically (Pap-test) as presenting minor cellular abnormalities, respectively ASCUS (10) and LSIL (119), and major cellular abnormalities, respectively SIL-borderline (8) and HSIL (21), and who, either voluntarily or upon cytopathologists' recommendation, were colposcopically examin...

Endoscopic surveillance is recommended for patients with Barrett's esophagus (BE) to detect high-grade intraepithelial neoplasia (HGIN) or early cancer (EC). Early neoplasia is difficult to detect with white light endoscopy and random biopsies are associated with sampling error. Fluorescence spectroscopy has been studied to distinguish non-dysplastic Barrett's epithelium (NDBE) from early neopl...
