The Leipzig Center for Wilson's Disease in the GDR is charged with the registration and diagnosis of all homozygous Wilson gene carriers, the clarification of all suspected cases, including the heterozygote test, and the co-ordination of long-term treatment. At present, there are 78 recorded Wilson gene carriers living. On the basis of our own comprehensive observations and investigations over prolonged periods of time, questions concerning pathogenesis, genetics, diagnosis and therapeutic measures, including their side-effects, are dealt with. 相似文献

The antidepressants trimipramine and imipramine were compared within the framework of a multiclinical study performed under the conditions of a controlled clinical experiment. There has been found a time-different remission of affective und psychomotoric symptoms. The panthymoleptic action of trimipramine and other antidepressants is discussed with reference to these results. Trimipramine influences psychotic states, especially if in depression anxiety is combined with agitation, also in hypochondriac forms of depression. 相似文献

The author, after pointing out the rare occurence and peculiarities of pattern-sensitive forms of epilepsy, reports the case of a seven-year-old boy with infantile cerebral paresis characterized by symptomatic attacks, who was observed to show absence-like conditions when looking at small-checkered patterns of nylon fabric. Grasping and looking at such fabrics assumed the form of an addiction, with a sense of pleasure being believed to be derived therefrom. Although anticonvulsive therapy resulted in attacks of epilepsy being no longer detectable clinically and by electroencephalography, seizures were still triggered by looking at patterns. Also discussed in this article is the problem of transition from real to psychogenic attacks. 相似文献

The variation in the speed of conduction of motor fibers of the ulnar nerve was determined by Hopf's double-stimulus method and compared with values obtained from the duration of muscular response potentials for differently spaced points of stimulation. However, the values obtained from the difference of the duration of response potentials are inadequate since the duration of potentials cannot always be determined accurately. After a ten-day administration of faustan (15 mg per day) or phenytoin (300 mg per day) there was observed a decrease especially in the minimum rate of conduction of motor fibers of the ulnar nerve. 相似文献
