A dermatologic decision support system that processes lexical knowledge from standard textbooks.

We present a decision support system that processes lexical fuzzy knowledge from standard pathology textbooks. The user can choose among four methods: full text and hypertext approaches (classic lexical retrieval methods) and two possibilistic, knowledge-based approaches (the fuzzy logic computation and an adapted evidence combination scheme based upon the theory of belief functions). All these methods, including their algorithms, are presented in this paper. The effectiveness of these approaches is demonstrated by examples from dermatopathology. At the top of the lists of differential diagnoses generated by the system the degree of conformity between the approaches is high.

[Diagnosis in the aged from the pathologic-anatomic viewpoint].

The preciseness of clinical diagnostics for two different age groups was reviewed among 2033 unselected autopsies looking at eight single diagnoses. The younger age group was up to 59 years of age, the older one over 59 years. In the older age group myocardial infarction, hepatocirrhosis, bronchial and gastric carcinomas were less frequently diagnosed compared to the younger group. Pulmonary embolism, pulmonary tuberculosis, colon and breast carcinomas were almost evenly diagnosed before death in both groups. The multimorbidity in aged patients is discussed. Also in the geriatric diagnostic a high autopsy rate--86% in our collective--is important.
