Prospective investigation has been undertaken with the aim to study the frequency, location and age and sex distribution of various histological types of benign gastric epithelial polyps. Histological type--adenomatous, hyperplastic and fundic gland polyps--was diagnosed on the basis of at least three histological samples taken from the polyp. Biopsy samples were also taken from the antrum and ...

PURPOSE The present study aimed to determine the prevalence of MUTYH mutations in patients with multiple colonic polyps and to explore the best strategy for diagnosing MUTYH-associated polyposis (MAP) in these patients. EXPERIMENTAL DESIGN This study included 405 patients with at least 10 colonic polyps each. All cases were genetically tested for the three most frequent MUTYH mutations. Whole...

BACKGROUND Familial adenomatous polyposis (FAP) is a disease inherited in an autosomal dominant fashion. Most FAP patients develop upper gastrointestinal polyps; especially those in the antrum and duodenum are usually neoplastic. The aim of this study was to evaluate the prevalence of gastroduodenal polyps in Iranian FAP patients. MATERIALS AND METHODS 28 patients affected by FAP underwent fr...

AIMS To determine the level of proliferative activity in 39 nasal polyps with clear cut distinct clinical behaviour patterns. METHODS The 39 nasal polyps included 11 polyps labelled as "single" and taken from the lateral nasal wall and the middle turbinate; 12 polyps labelled as "massive" and relating to diffuse polyposis involving the entire nasal cavity; six polyps labelled as "ASA" and rel...

INTRODUCTION Chronic rhinosinusitis with nasal polyps is a multifactorial disease entity with an unclear pathogenesis. Contradictory data exist in the literature on the potential implication of viral elements in adult patients with chronic rhinosinusitis. OBJECTIVE To compare the prevalence of human herpes viruses (1-6) and Human Papilloma Virus in adult patients with chronic rhinosinusitis w...

BACKGROUND The real accuracy of computed tomographic colonography (CTC) is still unknown. OBJECTIVE To perform a meta-analysis of the diagnostic accuracy of CTC for the detection of polyps and colorectal tumors. METHODS SELECTION OF STUDIES Studiesassessing the accuracy of CTC for the detection of colorectal polyps and tumors were selected. data synthesis: Meta-analyses combining sensiti...

Juvenile (retention) polyps are usually solitary lesions in the colorectum but may be multiple in juvenile polyposis. The association between juvenile polyps and colorectal neoplasia is controversial. We present three patients with juvenile polyposis who had colorectal adenomas or adenomatous epithelium in juvenile polyps at ages 3, 4, and 7 years. In a retrospective study of 57 additional pati...

BACKGROUND Colonic adenomatous polyps are premalignant lesions; early recognition and use of a polypectomy for these polyps can reduce the occurrence of colorectal cancer. The purposes of this study were to evaluate the complications of polypectomy and the relationship between the morphology and size of colonic polyps and their histology. METHODS Data on colonic polyps from 324 patients who r...

OBJECTIVE To ascertain the best management options for patients presenting with gallbladder polyps. DESIGN Retrospective case-note analysis. SETTING Tertiary referral teaching hospital practice. PATIENTS Patients with ultrasonography-detected gallbladder polyps. INTERVENTIONS Ultrasonography surveillance or surgery. MAIN OUTCOME MEASURES Demographic data and size and number of polyps were recor...

Endometrial polyps are a frequent finding in infertile patients. Little is known about the true prevalence of polyps in infertile patients. It is unproved whether polyps are causative of infertility, or whether surgical polypectomy by hysteroscopy improves the likelihood of successful conception. This article reviews endometrial polyps in reproductive-age fertile and infertile women.
