INTRODUCTION The anterior ethmoidal artery (AEA) is an important point of anatomical reference in order to locate the frontal sinus and the skull base. Notwithstanding, despite numerous endoscopic studies in cadavers, we still lack an anatomical study on the AEA in the western population. AIM to determine reference points used to locate the artery, study its relationship with the skull base a...

Endoscopic endonasal ligation of the AEA is not used frequently; there are few studies in the literature for standardization of the endoscopic technique for this vessel. AIM To demonstrate the feasibility of periorbital AEA ligation in a transethmoidal e...

Recently, p16 stromal expression has been reported in the examination of endometrial serous adenocarcinomas associated with polyps. Therefore, polyps are defined as preneoplastic formations some textbooks. Due to these different expressions cells polyps, we wanted present place tissue hyperplasia and differential diagnosis our review article.

Background & Objective: Most colorectal cancers (CRCs) arise from adenomatous polyps, and clinical management of this type of polyp is highly dependent on the reliability and validity of the pathological diagnosis. The aim of this study was to examine the interobserver agreement of five pathologists in assessing dysplasia in adenomatous polyps. Methods: I...

34 children aged 9 months to 12 years presenting with chronic and intermittent rectal bleeding were diagnosed as having colorectal polyps by fiberoptic colonoscopy performed under sedation. Bleeding per rectum (mean duration, 15 months) was the chief presenting symptom and was present in 97% of these patients. In 85% of patients polypectomy was carried out without using general anesthesia....

From June 1989, to June 1991, 58 patients with GI polyps were reviewed. Except two patients who had multiple polyps, 56 had only one polyp. The size of polyps were 0.5 to 3 em in diameter. 51 (75%) of polyps were located in the rectosigmoid region, 25 (37%) were in the rectum and 26 (38%) in the sigmoid. (Seventeen) (25%) polyps (two in right colon, four in transverse, and 11 in descending...
