Epidemiological studies propose a protective role for dietary fiber in colon cancer (CRC). One possible mechanism of fiber is its fermentation property in the gut and ability to change microbiota composition and function. Here, we investigate the role of a dietary fiber mixture in polyposis and elucidate potential mechanisms using TS4Cre×cAPCl°x468 mice. Stool microbiota profiling was performed...

BACKGROUND Nasal polyposis is a common nasal mass with unknown etiology. It has been assumed that allergy predisposes to polyp formation. Our objective was to compare the prevalence of food sensitization in medically resistant chronic rhinosinusitis patients with or without nasal polyposis. METHODS One hundred and fifty-five patients who fulfilled the inclusion and exclusion criteria were inc...

The evidence for genetic testing for the adenomatous polyposis coli (APC) mutation in individuals with a clinical differential diagnosis of attenuated familial adenomatous polyposis (aFAP), MUTYHassociated polyposis and Lynch syndrome, or individuals who are at-risk relatives of patients with FAP, includes a TEC Assessment. Outcomes of interest are overall survival, disease-specific survival, t...

Background: Colorectal cancer is the second most common cancer in the world which is mainly caused by epigenetic and environmental factors. Among these epigenetic factors, gut microbiota is an important one. Although it has not been proved a unique group of bacteria correlated with colorectal cancer, these findings have generally demonstrated differences between healthy and disease gut microbio...

Cap polyposis is extremely rare in children. We report a case of an 11-month-old male infant who visited our hospital because of rectal prolapse and small amount of hematochezia lasting several days. He also had an epidermal nevus in the sacral area. Colonoscopy showed erythematous, multilobulated, circumferential, polypoid lesions with mucoid discharge from the rectum. He was diagnosed with ca...

We describe the clinical scenario of a young male with history of non ulcer dyspepsia who had endoscopic evidence of gastric polyposis in antral area. The polyps disappeared four months after proton pump inhibitors were stopped. Proton pump inhibitors have been linked to gastric fundal polyposis and not antral gland polyposis. This is the first report originating from an Asian country describin...

Although inflammatory polyposis of the colon is a recognized local complication of ulcerative colitis, giant inflammatory polyposis that totally obliterates the colonic lumen is uncommon, and most of the patients have been from Western countries. We report a Japanese man who had localized giant inflammatory polyposis that obstructed the retrograde flow of barium in a double-contrast barium enem...
