The most frequent benign gallbladder polyps are cholesterol polyps. Next in frequency were adenomas, which may have malignant potential. The aim of this study was to assess the possibility of ultrasonography in the diagnosis and differential diagnosis of cholesterol polyps compared to adenomas. Patients were examined during the period from October 2006. to December 2008. In Department of Ultras...

OBJECTIVE To determine the association between pericolonic fat and colorectal polyps using CT colonography (CTC). METHODS A total of 1169 patients who underwent CTC and optical colonoscopy on the same day were assessed. Pericolonic fat was measured on CTC in a band surrounding the colon. Visceral adipose tissue volume was measured at the L2-L3 levels. Student's t-tests, odds ratio, logistic r...

INTRODUCTION Chronic rhinosinusitis with nasal polyps is a multifactorial disease with a complex pathophysiology involving multiple genetic and environmental factors. OBJECTIVE The purpose of this work review is to focus on the importance of genetic studies in chronic rhinosinusitis with nasal polyps besides the several barriers that exists for its understanding. METHODS A systematic review...

OBJECTIVE(S) To investigate the prevalence of microsatellite instability (MSI) in endometrial polyps and to evaluate whether there are clinical and histopathological parameters associated with this kind of instability. STUDY DESIGN Between September 2008 and April 2009, endometrial polyps were collected from 109 patients. MSI was evaluated using the NCI recommended markers BAT25, BAT26, D2S12...

BACKGROUND AND AIMS Colorectal adenomas are recognised as precursors of colorectal carcinomas. The significance of hyperplastic (metaplastic) colorectal polyps is unknown. The relationship between hyperplastic polyps and adenomas, and the prevalence and incidence of these lesions were evaluated in individuals predisposed to familial colorectal cancer. METHODS A total of 299 individuals partic...

INTRODUCTION The pathogenesis of nasal polyps is still not fully understood. AIM To analyze the topography and intensity of interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α), cyclooxygenase 2 (COX-2), nitric oxide synthase 2 (NOS-2), and nuclear factor-κB (NF-κB) expressions in eosinophilic and neutrophilic polyps and in normal nasal mucosa. MATERIAL AND METHODS The study included spe...

Antrochoanal polyps are benign lesions originating from the mucosa of the maxillary sinus. Nasal obstruction and rhinorrhea are their main symptoms. Their endoscopical and radiological appearance makes them relatively easy to diagnose. These polyps are usually presented unilaterally, although bilateral presentation is also possible. We described two cases of atypically giant antrochoanal polyps...

Background: In western countries with high prevalence of colorectal cancers, colonic polyps are usually adenomatous. There are few studies from Iran regarding to the predominant type of polyps in colorectal area. Objectives: We conducted this retrospective study to evaluate the predominant colorectal polyps in our center as the largest referral center of the South region of Iran. Material and M...

Introduction. Antrochoanal polyps (ACPs) occur most commonly in children and young adults. Antrochoanal polyps are associated with chronic sinusitis and/or allergy. The symptoms of ACPs are nasal obstruction, rhinorrhea, headaches and post-nasal drip. The treatment of choice is surgical. Material and methods. In the study we analyzed the clinical data of 19 children with antrochoanal polyps who...

choanal polyps are a form of nasal polyps that grow toward the choana with a single stalk. septochoanal polyp is a rare entity that originates from the mucosa of the nasal septum with choanal extension. the most common site of its origin is mainly the superior aspect of the posterior portion of the nasal septum. however, metaplastic ossification is a rare event in nasal polyp and to the best of...
