BACKGROUND The main goal of this paper is to investigate the frequency, clinical profile, and endoscopic findings of children and teenagers submitted to colonoscopies. METHODS Patients of below 18 years of age, diagnosed with polyps by means of colonoscopies at two reference centers of pediatric endoscopy were followed-up between 2002 and 2012. The clinical variables evaluated in this study i...

INTRODUCTION Peutz-Jeghers Syndrome (PJS) is an uncommon autosomal dominant hamartomatous polyposis syndrome. Morbidity arises from polyp-related complications and increased risks of malignancy. We report on PJS patients registered in the Singapore Polyposis Registry, identified principal causes of morbidity and appraised current management strategies. A followup protocol based on recent litera...

])'AN,IILIAL POLYPOSIS Of the colon w a s first described by Cripps* in 1882. Since then, case reports and family histories have been eagerly studied, and it has become appa ren t that m a n y pat ients afflicted wi th this disease have a tendency to develop adenocarc inoma in one or more polyps before they have a t ta ined the age of 50 years. 1~ I t was no t felt, 1, 4 however, tha t this pro...

BACKGROUND Juvenile polyposis syndrome, a rare disorder in children, is characterized with multiple hamartomatous polyps in alimentary tract. A variety of manifestations include bleeding, intussusception, or polyp prolapse. In this study, we present an 8-month-old male infant of juvenile polyposis syndrome initially presenting with chronic anemia. To the best of our knowledge, this is the young...

A FEW decades ago intestinal polyposis was regarded as a single entity, but increasing knowledge has led to the identification of a number of different syndromes. The term polyposis coli is usually taken to mean familial adenomatosis coli, a premalignant condition occurring in adolescents and adults. Although there have been many reports of colonic polyposis in children, discussions on the subj...

Allele-specific expression (ASE) of the Adenomatous Polyposis Coli (APC) gene occurs in up to one-third of families with adenomatous polyposis (FAP) that have screened mutation-negative by conventional techniques. To advance our understanding of the genomic basis of this phenomenon, 54 APC mutation-negative families (21 with classical FAP and 33 with attenuated FAP, AFAP) were investigated. We ...

Although inflammatory polyposis is one of the common complications in patients with inflammatory bowel disease, it is rare that each poly grows up to more than 1.5 cm. We describe a case of localized giant inflammatory polyposis of the ileocecum associated with Crohn's disease. A 40-year-old man who had been followed for 28 years because of Crohn's disease was hospitalized for right lower abdom...

In normal upper airways, nitric oxide is generated by the paranasal sinus epithelium and then diffuses into the nasal cavities. This study examined whether or not nasal NO concentration is affected by paranasal sinus inflammatory diseases. The influence of obstruction (nasal polyposis) and/or inflammation (allergy or chronic sinusitis) of the paranasal sinuses on nasal NO concentration was eval...

BACKGROUND Allergic rhinitis and nasal polyposis are common nasal diseases, but the available treatment modalities have only limited success. OBJECTIVE To assess the therapeutic effect of low-energy narrow-band red light phototherapy on nasal clinical symptoms of allergic rhinitis and nasal polyposis. METHODS In a double-blind randomized prospective study, 50 patients with allergic rhinitis...

OBJECTIVE To demonstrate the long-term efficacy of intranasal furosemide, an inhibitor of the sodium chloride cotransporter channel at the basolateral surface of the respiratory epithelial cell, vs no therapeutic intervention vs intranasal mometasone furoate, a corticosteroid, in preventing relapses of chronic hyperplastic sinusitis with nasal polyposis. DESIGN Randomized prospective controll...
