PURPOSE Leukotrienes and prostaglandins, products of arachidonic acid metabolism, sustain both systemic and lesion-localized inflammation. Tumor-associated Inflammation can also contribute to the pathogenesis of colon cancer. Patients with inflammatory bowel disease (IBD) have increased risk of developing colon cancer. The levels of 5-lipoxygenase (5-LO), the key enzyme for leukotrienes product...

Using a computer database, the author investigated the histopathology of 10 000 consecutive gastric specimens, taken in the last 12 years (2002-2013) at the pathology laboratory of a Japanese hospital. Re-observation of the already examined histological sections was done when the histological diagnosis and findings on the computer data base were not very obvious. The gastric specimens were iden...

Malignant change occurred in a benign, recurrent vaginal müllerian polyp. The patient, a 49 year old woman with cerebral palsy, presented with a polypoid mass in the vagina. At four years of age she had presented with a haemorrhagic polyp, and over the following years she had recurrent irregular bleeding and regrowth of the polypoidal mass, requiring a total of 10 operations to excise the polyp...

A fibro-epithelial polyp is the most common epithelial benign tumor of the oral cavity. Such a polyp is of mesodermal origin and it is a pink, red, or white knob-like painless growth that is sessile or pedunculated. A fibro-epithelial polyp commonly occurs on buccal mucosa, the tongue, or the gingiva. A fibro-epithelial polyp is an inflammatory hyperplastic lesion in response to chronic irritat...

In this paper we describe the development of a computationally efficient computer-aided detection (CAD) algorithm based on the evaluation of the surface morphology that is employed for the detection of colonic polyps in computed tomography (CT) colonography. Initial polyp candidate voxels were detected using the surface normal intersection values. These candidate voxels were clustered using the...

Aim Polyp is called formations protruding into the lumen in the gastrointestinal tract. In this study, we aimed to determine frequency, anatomic distribution within the large bowel and pathologic types of colon polyps based on the colonoscopy results. Materials and methods The colonoscopy reports between 2010 and 2011 were analyzed retrospectively. Complaint of the patients on admission, the ...

Objective: Several factors play role in colorectal carcinogenesis. Among these factors, helicobacter pylori infection is supposed to be one of the causative factors. Previous studies were focused on investigation relationship between existence and colon carcinomas by particular serological diagnostic tests. The aim our study was determine effect severity inflammation related this non carcinoma ...

In a case-control study, the authors investigated relations between plasma carotenoid concentrations and the prevalence of colorectal adenomatous polyps (precursors to colorectal cancer) in residents of Los Angeles County and Orange County, California, from 1991 through 1993. Plasma concentrations of six carotenoids were compared in 472 asymptomatic cases with a first-time diagnosis of at least...

IMAJ • Vol 2 • October 2000 G6PD and Israeli Spotted Fever 781 even with high current. A possible explanation may have to do with impaired conductivity through fat. A lipoma should be sought whenever a huge smooth polyp is identified in the descending colon. Further verification can be obtained with the help of CT, where there is a uniform hypodense polyp. On CT, absorption densities of -80 to ...

Inflammatory fibroid polyp (Vanek tumor) is a rare benign lesion which originates from the submucosa of the gastrointestinal tract. The most common locatization is the gastric antrum. Although the etiopathogenesis is unknown, it is thought that inflammatory fibroid polyps are the result of reactive inflammatory processes because of their eosinophilrich stroma. Microscopically, fibrous connectiv...
