Trauma in the United States is the leading cause of death and disability in the pediatric population. Differences of age and development affect recovery and outcome following head injury. ⋯ Treatment and management should be tailored to each case in order to effect a positive outcome with respect to brain functioning. Aggressive intervention for prevention of primary and secondary injury must be continued and understanding of the impact of these injuries should provide for a brighter future for these patients.

Extracorporeal membrane oxygenation is an effective rescue treatment for severe cardiorespiratory failure in term or near term neonates, although cerebral palsy, mental retardation, and sensorineural hearing loss are observed in 10 to 20% of survivors. The objective of the present study was to identify potential risk factors that may explain the neurologic and audiologic sequelae noted in 19% of 181 survivors of neonatal extracorporeal membrane oxygenation from our hospital. Our results suggest the following findings in survivors of severe cardiorespiratory failure treated with neonatal extracorporeal membrane oxygenation: (1) hypotension or the need for cardiopulmonary resuscitation before extracorporeal membrane oxygenation significantly increases the risk of spastic cerebral palsy, (2) profound hypocarbia before extracorporeal membrane oxygenation is associated with a significantly increased risk of hearing loss, (3) mental retardation in the absence of spastic cerebral palsy is unexplained except when due to abnormal fetal brain development, and (4) hypoxemia in the absence of hypotension does not increase the risk of neurologic or audiologic sequelae.

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.

There is an established link between congenital heart disease and acquired brain injury, which relates to the dependence of the nervous system on a consistent and responsive supply of oxygen and glucose. The advances in the field of infant cardiac surgery have presented new and different challenges to the arena of child neurology. This review provides an overview of the mechanisms of neurologic injury and cerebral hemodynamics and metabolism during cardiac surgery. This review discusses current and future strategies for the management of children with congenital heart disease.
