Somatosensory evoked potentials in hemimegalencephaly and lissencephaly: anatomo-functional correlations.

Four patients with hemimegalencephaly and four with lissencephaly were studied by median nerve somatosensory evoked potentials. The peripheral conduction velocity and the conduction time between the brachial plexus (Erb's point) and cervical cord were normal in both malformations. In hemimegalencephaly, the cortical components were absent on the malformed hemisphere but normal on the healthy side, whereas in lissencephaly an abnormal, prolonged N20 wave was recorded bilaterally. The difference presumably relates to the absence of normal cortical lamination in hemimegalencephaly and to the presence of a 'four-layered' cortex in lissencephaly.

Farber lipogranulomatosis: an unusual presentation in a black child.

Farber disease, a rare, inherited condition of lipid metabolism usually appears within the first two months of life. The patients may die in the first few years of life or may live into the second decade. We believe this patient to be the first black American reported with Farber disease. Additionally, the characteristics of the disease in this patient were at variance with previously reported cases.

Frequency of agenesis of the corpus callosum in the developmentally disabled population as determined by computerized tomography.

Agenesis of the corpus callosum (ACC) is an infrequent congenital abnormality that has been diagnosed by necropsy, surgery, pneumoencephalography, computerized tomography (CT), and magnetic resonance imaging. The reported prevalence has varied as a function of disability status of the population studied and diagnostic technique. This report found 33 cases of ACC in a consecutive series of 1,447 CTs of developmentally disabled individuals. The prevalence, 2.3%, is consistent with studies using other techniques. However, the significantly higher (p less than 0.01) rate from 1978 to 1979 suggests an initial tendency of neuroradiologists to over-diagnose ACC, and CT data from the 1970s may need to be reexamined.
