Use of subdural grids and strip electrodes to identify a seizure focus in children.
For patients with intractable seizures, the best surgical outcome is achieved following precise localization of the seizure focus. Scalp EEG monitoring may be insufficient and chronic subdural invasive EEG monitoring has therefore been advocated. At Children's Hospital in Boston, 31 children had chronic subdural monitoring from January 1990 through June 1994. ⋯ During monitoring, cortical stimulations were performed to localize speech and somatosensory areas. There was only one complication, a subdural hematoma in a patient who had had previous surgery. Chronic subdural EEG monitoring is helpful in precisely localizing seizure foci in pediatric patients; it also allows motor and speech mapping and appears to be a safe modality in children.

Acute subdural hematoma associated with cerebral infarction in the full-term neonate.
Acute subdural hematomas in the full-term neonate are usually thought to be a manifestation of birth trauma. Most commonly, these hematomas are associated with a tentorial tear, and less frequently are secondary to damage to the occipital sinus accompanying occipital osteodiastasis, or to rupture of bridging superficial cerebral convexity veins. We report 6 cases of acute subdural hematoma associated with cerebral infarction (SDH/CI) in term neonates, an entity which has not been well-documented previously. ⋯ The outcome in 3 patients, who have been followed for more than 1 year, has been good, with some mild focal neurologic deficits, but no seizure activity. The pathogenesis of this entity is unclear, but the acute subdural hematoma in these cases is probably secondary to the cerebral infarction. Recognition of SDH/CI as a specific entity in term neonates has significant management and possibly medicolegal implications.

Reduction cranioplasty can greatly improve the quality of life for selected patients with severe macrocephaly and can significantly diminish some of the difficulties in the long-term chronic care of others. Because of differences in age, cranial morphology and surgical goals, the surgical plan must be tailored to the individual patient. ⋯ Four patients, representing the spectrum of severe macrocephaly and also the problems associated with reduction cranioplasty, are presented. Surgical indications, tactical considerations and risks are discussed.

Results and complications of intracranial pressure monitoring in 303 children.
303 consecutive children who had insertion of an intracranial pressure (ICP) monitor for various reasons were reviewed to determine clinical value and complications rate of ICP monitoring in this age group. 286 patients had a Camino fiberoptic monitor. Of the remaining cases, 9 had a ventricular catheter, 7 had an extradural Gaeltec monitor, and 1 had a subdural feeding tube. The reasons for monitoring the ICP were: trauma in 132 children, postoperative monitoring after tumor surgery in 91, head injury due to child abuse in 30, severe medical conditions such as meningitis, encephalitis, and near-drowning in 30, intracranial hemorrhage in 15, and hydrocephalus in 5 children. ⋯ The outcome in all 303 children correlated with averaged readings of ICP over 24 h and initial Glasgow coma score, but did not correlate with initial ICP measurements. Complications of monitoring were few and consisted of infection in 1 (0.3%) child, intracranial hemorrhage in 1 (0.3%) who had low platelet counts, displacement of monitor in 3 (1%), and malfunction of monitor in 8 (2.6%) children. We conclude that ICP monitoring in the pediatric age group substantially influences our clinical management of unconscious children and is safe.

Delayed and progressive brain injury in children and adolescents with head trauma.
We performed serial CT scans on 351 children and adolescents with serious closed-head injury. Delayed or progressive lesions were encountered in 145 (41%). ⋯ The presence of delayed cerebral injury had a profound influence on survival and recovery from head trauma, especially when the initial severity of the head injury was taken into account. We conclude that serial CT scans provide a reliable means of diagnosing and following the progress of delayed cerebral injury in the pediatric population.
