We have developed a method for the routine primary culture of human colonie epithelial cells. Cultured cells exhibited char acteristic epithelial structures, including a brush border and junctional complexes. Flask-like goblet cells containing mucus were also seen within the epithelial monolayer. [3H]Thymidine labeling indices were used to distinguish between cultured cells from familial polypo...

BACKGROUND Inflammatory bowel disease (IBD) and familial adenomatous polyposis (FAP) are uncommon diseases and both are associated with marked increased risk of colorectal cancer. METHODS We present a patient diagnosed in parallel with ulcerative colitis and FAP. Mutational analysis of the APC germline and somatic DNA was performed by sequencing. RESULTS This patient's phenotype consisted o...

INTRODUCTION Previous studies have suggested the use of soluble CD26 (sCD26) as a tumour marker for the detection of colorectal cancer (CRC) and advanced adenomas. The aim of this study was to assess the sCD26 concentration in a large cohort to evaluate its association to epidemiologic parameters and CRC-related symptoms/pathologies. SUBJECTS AND METHODS Serum samples were collected from 2,75...

A 20-year-old woman presented for a routine eye examination. Her best-corrected visual acuity was 20/20 in the right eye and 20/25 in the left eye. Fundus examination revealed in both eyes the presence of multiple egg-shaped hyperpigmented retinal lesions (at least 4), sur-rounded by a depigmented halo(figure 1, black arrows). The appearance of these lesions was suggestive of congenital hypertr...

PURPOSE The aim of this study was to examine the effect of a specific cyclooxygenase-2 inhibitor, rofecoxib, on rectal polyps in familial adenomatous polyposis patients. EXPERIMENTAL DESIGN This was a randomized, double-blind, placebo-controlled study of the efficacy and safety of rofecoxib in the rectum. Initially, 21 patients were assigned randomly in a 1:1 ratio to receive either 25 mg rof...

Colorectal Cancer (CRC) in developed countries is the major causes of cancer death. It may have sporadic or hereditary origin. Familial Adenomatous Polyposis (FAP) is a very frequent hereditary syndromes predisposing to Colorectal Cancer and is characterized by the development of numerous precancerous polyps (from hundreds to thousands) in the second decade of life. Classical FAP is caused by g...

Familial adenomatous polyposis (FAP) is an autosomal dominant precancerous condition, clinically characterized by the presence of multiple colorectal adenomas or polyps. Patients with FAP has a high risk of developing colorectal cancer (CRC) from these colorectal adenomatous polyps by the mean age of diagnosis at 40 years. Germline mutations of the APC gene cause familial adenomatous polyposis ...

Ganglioneuroma (GN) of the gastroin-testinal (GI) tract is rare tumor composed of ganglion cells, nerve fibers, and supporting cells of the enteric nervous system. Diffuse ganglioneuromatosis is associated with multiple endocrine neoplasia IIB (MEN IIB), neurofibro-matosis type I (NF1, also known as von Recklinghausen disease), multiple cu-taneous or GI tract neurofibromatosis, and neurogenic s...
