In this paper we reported a patient with multisystem failure, whose EEG immediately preceding death demonstrated a unique combination of suppression-burst pattern, generalized epileptiform discharges, and alpha-theta pattern coma. Post-mortem examination showed ischemic-anoxic lesions involving cortical and sub-cortical gray matter. The lack of white matter(More)
To determine the role of ventricular shunts as a cause of seizures in children with hydrocephalus, 190 patients with myelomeningoceles were studied. There was a low incidence of seizures (2%) in the nonshunted patients in spite of a high incidence of ventriculomegaly, whereas the overall frequency of seizures in shunted patients was 22%.

This study was conducted to determine if the resistive index (RI) could be used for the examination and follow-up of neonates with increased intracranial pressure. First, in a laboratory model with four mongrel dogs, RI was found to correlate linearly with cerebral perfusion pressure. Second, RI was studied in 57 healthy neonates and 285 neonates with(More)
Using pulsed Doppler ultrasound through the sonic window of the anterior fontanelle in infants, 46 children with ventriculomegaly had sequential evaluations of Resistive Index for comparison with the need for ventriculoperitoneal shunting. Hydrocephalus was associated with myelomeningocele in 17 patients and posthemorrhagic, postmeningitic, or congenital(More)
Previous studies have demonstrated a high correlation between hydrocephalus and the resistive index (RI), as determined by transcranial Doppler ultrasonography. Measurements of RI, calculated by dividing the difference between the peak systolic velocity and the end-diastolic velocity by the peak systolic velocity, were attempted in 55 pediatric patients(More)
