[Information and statistics in pathological anatomy].

The theme is centred on the topics: informatics without computer-stitistics without numbers. Informatics without computers: the development of electronic data processing in medicine and especially in pathology has demonstrated that we are still far from clear text processing or automated diagnosis. An essential reason is seen in the fact that the present nomenclature allows no clear distinction between the terms of entity of disease and diagnosis. An exact differentiation between these terms is prerequisite for a further development of data processing. Statistics without nombers: In a larger interdisciplinary study we examined how the known risk factors to arteriosclerosis and myocardial infarction can be correlated upon the morphometrical explored patho-anatomical changes of the coronary vessel system. The method used was the factor analysis. In about 30% of the observed cases (total number: 419) the morphologic aspect alone and under simultaneous consideration of the risk factors did not sufficiently explain the patho-anatomically detected myocardial infarctions. As a possible explanation of this phenomenon the simultaneous and concordant attack of the intramural coronary vessels is being discussed.
