MATERIALS AND METHODS We retrospectively analyzed the records of nine children with the diagnosis of PRES. RESULTS Of the nine patients, seven were receiving immunosuppressive(More)
OBJECTIVE To compare the efficacy and side effects of hypertronic saline and mannitol use in cerebral edema. DESIGN Retrospective study. SETTING Pediatric intensive care unit. SUBJECTS 67 patients with cerebral edema. METHODS Patients with cerebral edema treated with either mannitol or hypertronic saline (HS) (Group II: n = 25), and both mannitol(More)
In an attempt to find the risk of relapse and factors predictive of risk of relapse, 97 children with epilepsy, withdrawn from their medication, followed in our outpatient clinic from 1990 to 1995 were included in this study. The overall relapse rate was 20.6%. All relapses occurred within 2 years after withdrawal started. Female gender, age at onset of(More)

Inherent abnormalities of myelin have been suggested in the pathogenesis of multiple sclerosis (MS). We investigated myelin in acute disseminated encephalomyelitis (ADEM) patients by magnetic resonance spectroscopy (MRS) and cerebrospinal fluid (CSF) analysis for citrulline, a marker of immature myelin. A citrulline peak was observed in the normal appearing(More)
