[Electric abdominal epidutaneous findings in the pathology of colonic motility].

Abdominal epicutaneous electrical activity has been studied in a group of 58 gastroenterically normal subjects or suffering form colon motor pathology. An evident similarity of behaviour was observed in the various groups: 17 out of 18 subjects with irritable colon and 6 out of 7 with subocclusion of the colon presented waves with characteristic amplitude and frequency. This type of electrical activity was present in only 1 normal subject out of 20; 11 patients with paralysis of the colon did not present waves of note; three patients with ulcerative colitis showed behaviour similar to the majority of the normal subjects. The technique illustrated would appear adequate for the study of colon pathology with motility alterations.

The contribution of the cerebellum to mental and social functions in developmental age.

Here are present the data concerning the intellectual, language and frontal performances of 24 children who had undergone surgery because of cerebellar hemispheric or vermis tumors and one girl with viral cerebellitis. The children with right cerebellar tumors presented auditory sequential memory and language processing disturbances; those with left cerebellar tumors showed deficits in spatial tests and visual sequential memory. The girl with cerebellitis showed a complex neuropsychological picture with impairment in processing language and in general sequential functions. Lesions of the vermis lead to two pictures: 1) a postsurgical mutism that could be subdivided into speech disorders (even to the extent of anarthria) and true language disturbances similar to frontal aphasia; and 2) behavioral disturbances ranging from irritability to a truly autistic response. These data seem to support the recently attributed role of the cerebellum as a modulator of the superior mental and social functions.
