The Vienna classification of gastrointestinal epithelial neoplasia (2000)
Schlemper, R J ; JFA; CORA, Riddell, R H, Kato, Y, Borchard, F, Cooper, H S, Dawsey, S M, ...
BACKGROUND: Use of the conventional Western and Japanese classification systems of gastrointestinal epithelial neoplasia results in large differences among pathologists in the diagnosis of...

We developed a buffered azide-free urea medium which is sensitive, specific, and nontoxic for rapid detection of Campylobacter pylori in gastric biopsies. Detection of urease produced by the organism...
Streutker, C. J., Bernstein, C. N., Chan, V. L., Riddell, R. H., Croitoru, K.
The inflammatory bowel diseases are considered an abnormal host immune response to an environmental stimulus. Evidence suggests a role for intestinal bacteria in initiating and/or providing an...
Trimethoprim as an additional selective agent in media for the isolation of N. gonorrhoeae
The incorporation of trimethoprim into existing selective media using either saponin-lysed blood agar or chocolate agar as the base is suggested for the routine isolation of the gonococcus. The...
Barrett's esophagus. Comparison of benign and malignant cases.
Skinner, D B, Walther, B C, Riddell, R H, Schmidt, H, Iascone, C, DeMeester, T R
Using strict criteria for diagnosis, 23 patients having benign Barrett's esophagus, and 20 patients with adenocarcinoma arising in this epithelium have been analyzed. Evidence supports severe...
Oesophagoscopy, biopsy, and acid perfusion test in diagnosis of "reflux oesophagitis".
Sladen, G E, Riddell, R H, Willoughby, J M
The results of fibreoptic endoscopy have been assessed retrospectively in 71 patients referred for consideration of the oesophagus as the possible or probable cause of their symptoms. Gross...

Distribution of collagenous colitis: utility of flexible sigmoidoscopy.
Tanaka, M, Mazzoleni, G, Riddell, R H
We investigated the distribution of the collagen band in 33 patients with collagenous colitis to estimate the likelihood of the disease being diagnosed in biopsy specimens from the left side of the...
Riddell, R H, Tanaka, M, Mazzoleni, G
The use of oral non-steroidal anti-inflammatory drugs (NSAIDs) in 31 patients with collagenous colitis and in 31 matched control patients with irritable bowel syndrome or colonic diverticular disease...
Of 111 carcinomas developing in 73 patients with ulcerative colitis, 46 (41·5%) arose in the rectum where they are directly accessible to sigmoidoscopy. Fifty-eight per cent of single carcinomas...
Boland, C R, Lance, P, Levin, B, Riddell, R H, Kim, Y S
A group of 18 patients with stable ulcerative colitis involving the entire colon for at least eight years was subjected to a biopsy of normal appearing rectal mucosa and followed prospectively over...
Indeterminate colitis (IC) originally referred to those 10–15% of cases of inflammatory bowel disease (IBD) in which there was difficulty distinguishing between ulcerative colitis (UC) and...
MacNeill, K N, Riddell, R H, Ghazarian, D
Benign apocrine lesions have been described in the anogenital region, although according to the World Health Organisation convincing examples of anal apocrine adenocarcinomas have not been published....
Levin, B., Lennard-Jones, J., Riddell, R. H., Sachar, D., Winawer, S. J.
In chronic ulcerative colitis, the object of surveillance is prevention of cancer or at least prevention of death from cancer by diagnosis at an early curable stage or by detection at a pre-malignant...
