Relative sensitivity of colonoscopy and barium enema for detection of colorectal cancer in clinical practice.
TLDR
Hospital quality assurance committees and/or third-party payors should review the sensitivity of barium enema and Colonoscopy by practitioners in their institutions when sensitivity deviates significantly below the standard set by gastroenterologists performing colonoscopy in this study. Expand
Failure of colonoscopy to detect colorectal cancer: evaluation of 47 cases in 20 hospitals.
TLDR
Several factors that might improve the quality and sensitivity of colonoscopy are suggested: examiners should receive adequate training, cecal intubation rates should be high, and cecAL intubations should be verified by specific landmarks in all cases. Expand
Phosphoserine as a recognition determinant for glycogen synthase kinase-3: phosphorylation of a synthetic peptide based on the G-component of protein phosphatase-1.
TLDR
The work provides another example of a substrate for GSK-3 and demonstrates that the action of G SKS-3 is linked to the presence of phosphate in the substrate and not theaction of any particular protein kinase. Expand
The evolution of pyoderma gangrenosum. A clinicopathologic correlation.
TLDR
It is found that histopathologically, pyoderma gangrenosum evolves from folliculitis and abscess formation; it may also show leukocytoclastic vasculitis. Expand
Neoplasia distal to the splenic flexure in patients with proximal colon cancer.
TLDR
It is estimated that 30% of all patients with colorectal cancer would have a negative screening flexible sigmoidoscopy, suggesting that ongoing evaluation of colonoscopy as a general screening test is appropriate. Expand
