    Notes: [Auszug] Let us look at a molecule S at a distance d from the planar interface between different dielectric bodies. It induces oscillating dipoles in all volume elements in these bodies and the field at S produced by these dipoles may be obtained as the sum of the contributions of each volume element. ...

    Notes: Summary To find common factors for colonic-neoplasias and skin-tags, 157 inpatients, who consecutively had a coloscopy because of intestinal complaints, were intensively examined dermatologically. Regression-analyses showed that the number of colonic polyps were age- (p=3×10−8) and sex-dependent (1.9×10−2) and skin-tags had no influence on the number of colonic polyps. The size of colonic polyps also showed a clear age dependency (p=3×10−8). The number of skin-tags were dependent on weight (p=9×10−3) and age (p=1.3×10−2), its size on the interaction of sex and triglyceride-levels (p=3×10−8). Discriminant-analyses identified the following factors as important: age and triglyceride-concentration to recognize a patient with colonic polyps; age, positive Haemoccult®-test and number of skin-tags to recognize a patient with tubulovillous adenomas or colonic carcinomas. The essential common factor of colonic polyps and skin-tags was the age. For the recognition of a patient with colonic polyps the age was the most essential factor, skin-tags, on the contrary, were unimportant. The association between colonic polyps and skin-tags therefore was merely an effect of age.
