[Structural differentiation of psychological performances in epilepsy patients].

Investigating the specific of psychic performance disorders in epileptics structural aspects in addition to quantitative performance differences are considerable. We compared psychometrically obtained performance structures of epileptic children and adults and of parallelised healthy control persons. It became evident, that the performance differentiation hypothesis is to corroborate also in epileptic patients. The psychic performance structure of epileptics is characterized by a lower differentiation level of the basis functions underlining the performances. Our factor analytic investigations emphasize the importance of deceleration of psychic/psychomotoric speed in epileptics as primary basic disorder.

[Specific aspects of psychological disorders of performance in children with epilepsy].

We examined 49 normal intelligent epileptic and parallelised in sex, age and intelligence just as much healthy and 14 minimal cerebral damaged children without seizures. Using a psychological test battery psychic/psychomotor speed, flexibility/preservation proneness, memory span and memory and concentration were registrated. Besides reduced memory performances we found a deceleration of psychic/psychomotor speed as primary basic disorder within the performance structure of epileptic children analogous to our previous examined adults. The tridimensional comparison suggests remarkable psychopathological differences among the two groups of patients.

[Follow-up studies of high-risk children at the time of entering school in comparison with a normal group].

Somatic, neurological and psychological follow-up examinations performed on 54 high-risk children for school enrollment gave no significant differences in comparison with a randomized equal number of normal control children, with regard to physical development and maturation as indicated by carporadiograms. So far as neurological development was concerned, there was a slightly more frequent occurrence of minimal defects and, anamnestically, a marked retardation in the mastering of static functions (running) and speech development in the high-risk group. The results were in correlation with the psychological test findings. Here, too, a more frequent occurrence of impaired intellectual functions was found, which led to a greater number of deferments, conditional enrollments and transfers to special schools. Prospective examinations afford better opportunities of etiologically classifying and registering defects, including light forms. In this connection problems of screening are also discussed.

[Malabsorption caused by HBsAg-positive panareteritis nodosa].

A 36 year old man with panarteriitis nodosa (PAN) presented over a certain period of time meinly with gastrointestinal symptoms. He was HBsAg positive and a "reactive" hepatitis with histologically demonstrated. Arterial microaneurysms and stenoses were detected by angiography in the liver, kidney and small intestine. These findings were confirmed by autopsy. Vascular occlusions had caused infarctions of the small intestine as well as necroses and ulcerations of the large bowel. Chronic ischemia is considered as cause of the patient's malabsorption-syndrome. It is suggested, that cachexia of PAN may be partly due to malabsorption.
