INTRODUCTION Women presenting with unhealthy cervix needs to be evaluated with Papanicolaou (Pap) smear for epithelial abnormalities. AIM To detect epithelial cell abnormalities in unhealthy cervix using the 2001Bethesda system of reporting for cervical cytology and to confirm histopathologicaly the findings of Pap smear. MATERIALS AND METHODS In this study, 125 women with clinical diagnosi...

Endocervical polyp represents as a benign, exophytic lesion constituted of variable admixture proliferating endocervical glandular epithelium and metaplastic squamous permeated with fibro-vascular core. The commonly encountered is frequently accompanied by chronic inflammation, erosion superficial epithelial surface reactive alterations layering epithelium.

background and aim: oral mucosal lesions have various prevalence rates among different populations. few studies have evaluated the frequency of oral mucosal lesions in iranian population. this study aimed to determine the frequency of oral mucosal lesions and the related factors.                        materials and methods: this descriptive study was conducted based on the data in the archives...

We evaluated micronucleus and apoptosis occurrence among women with normal smears and women with different kinds of cervical abnormalities, i.e., inflammatory processes and low- and high-grade squamous intraepithelial lesions (N = 12, N = 10 and N = 27, respectively). The sample included 59 women who were seen at a public medical service for cervical cancer prevention in Feira de Santana, Bahia...

The tumor suppressor gene Apc (adenomatous polyposis coli) is a member of the Wnt signaling pathway that is involved in development and tumorigenesis. Heterozygous knockout mice for Apc have a tumor predisposition phenotype and homozygosity leads to embryonic lethality. To understand the role of Apc in development we generated a floxed allele. These mice were mated with a strain carrying Cre re...

BACKGROUND AND OBJECTIVES To investigate the differences in the number of squamous epithelial cells carried to the spinal canal by three different types of spinal needle tip of the same size. METHODS Patients were allocated into three groups (Group I, Group II, Group III). Spinal anesthesia was administered to Group I (n=50) using a 25G Quincke needle, to Group II (n=50) using a 25G pencil po...

BACKGROUND Although oral lichen planus has been classified by the World Health Organization (WHO) as a potentially malignant disorder, such classification is still the target of much controversy. AIM To evaluate the cell proliferation rate in oral lichen planus, comparing it to the rate observed in epithelial dysplasia and oral squamous cell carcinoma, aiming at indications which might indica...

Squamous cell carcinoma in the lung originates from bronchial epithelial cells that acquire increasingly abnormal phenotypes. Currently, no known biomarkers are clinically efficient for the early detection of premalignant lesions and lung cancer. We sought to identify secreted molecules produced from squamous bronchial epithelial cells cultured with organotypic culture methods. We analyzed prot...

OBJECTIVE To describe an unusual variant of oral epithelial dysplasia and to provide an appraisal of its immunohistochemical profile. STUDY DESIGN An unusual form of epithelial dysplasia, which we have termed adenoid dysplasia, was evaluated for staining of cytokeratins AE1/AE3, vimentin, E-cadherin, and β-catenin. The immunohistochemical results were compared with those observed in moderate ...
