The present study evaluated neurophysiologic function of the primary sensorimotor cortex in juvenile neuronal ceroid lipofuscinosis. A 122-channel magnetometer, which allowed studies of the somatosensory system in millimeter and millisecond precision, was used to record somatosensory evoked magnetic fields to median nerve stimulation from 10 patients and their matched control subjects. In both patients and controls, the somatosensory evoked magnetic fields from primary sensorimotor area typically consisted of N20m, P35m, and P60m deflections. ⋯ Both deflections showed a significant positive correlation with the disease duration: the sources were stronger in the older patients than in the younger ones. P60m deflections were normal or reduced in the patients. The results indicated increased thalamocortical excitability in the sensorimotor cortex in juvenile neuronal ceroid lipofuscinosis.

Review Clinical Trial
Intravenous immunoglobulin as therapy for pediatric Guillain-Barré syndrome.
Seven children with Guillain-Barré syndrome were treated with intravenous immunoglobulin. Median patient age was 5.8 years. A standard dosage of 0.4 g/kg/day for 5 days was administered. ⋯ There were no complications with intravenous immunoglobulin therapy except for a brief episode of hypotension in one patient. Review of the literature identified 74 additional children with Guillain-Barré syndrome successfully receiving intravenous immunoglobulin therapy. We suggest intravenous immunoglobulin as initial therapy for pediatric Guillain-Barré syndrome, because it appears equally as effective as plasmapheresis and is associated with fewer complications.
