    Notizen: Summary In a double blind study, planned as a 7×7 latin square, three oral doses of futonidin (0.5, 1, 2 mg), of clonidine (0.0075, 0.150, 0.300 mg) and of a placebo were administered to 7 normal volunteers on 7 different treatment days, with an interval of 3 days. On each treatment day sitting blood pressure, heart rate and reaction time were measured, and sedation and dry mouth evaluated before and 1, 2, 3, 4, 6, and 8 h after administration. The placebo did not modify the basal value of any variable. Flutonidin and clonidine produced dose-related effects on blood pressure, heart rate, sedation and dry mouth, but did not influence reaction time. Analysis of the dose-response curves demonstrated that the effect of flutonidin was one-fifth to one-twelfth that of clonidine, depending on which variable was considered.

    Notizen: Abstract From 1979 to 1982, 1233 symptom-free subjects at high risk for colon cancer because of family history and/or personal history of bowel neoplasia (cancer or adenomatous polyp) were examined with a guaiac test (Hemoccult II) for occult blood in stools. The test was positive (H+) in 98 subjects (7.9%). Endoscopy was subsequently performed on 86% of the H+ and on 64% of the H-subjects. Of 20 in invasive cancers found, 15 had been H+ [75.0%; 95% confidence interval (CI), 54.3–91.0%]. Of 96 patients with adenoma(s), 23 were H+ (24%; 95% CI, 16.0–33.0%). However, the sensitivity for adenomas was higher in patients with multiple adenomas or with a single adenoma measuring 2 cm or more in its largest diameter (37.5%; 95% CI, 21.8–54.7%). Of 699 subjects free of neoplastic lesions at endoscopy, 47 had been H+, ie, false positive (6.7%; 95% CI, 5.0–8.7%). Adjusting for differential compliance of H+ and H-subjects to endoscopy, a corrected estimate for sensitivity would be 69% for cancer and 19% for adenomas; the corrected estimate for the false-positive rate would be 5%.
