Iomazenil hyperfixation in single photon emission computed tomography study of malformations of cortical development during infancy.

We present 2 cases of malformations of cortical development and early onset epilepsy. The first case is of a patient with left hemimegalencephaly who developed focal epilepsy at the age of 2 days and cluster spasms at 1.5 months.

Effectiveness and safety of non-intravenous high-dose phenobarbital therapy for intractable epilepsy during childhood.

High-dose phenobarbital (PB) therapy is effective for refractory status epilepticus. We reviewed medical records of patients with intractable partial epilepsies on whom performed non-intravenous high-dose PB therapy. Thirteen patients received PB rectally or orally at a dosage of 20-30mg/kg/day initially, and the PB dosage was gradually reduced to a maintenance dosage of 5-10mg/kg/day orally.

Interictal cerebral blood flow abnormality in cryptogenic West syndrome.

Purpose: To elucidate the abnormality of interictal regional cerebral blood flow (rCBF) of West syndrome at the onset.

Methods: Quantitative measurement of rCBF with an autoradiography method using N-isopropyl-((123)I) p-iodoamphetamine single photon emission computed tomography (SPECT) was performed on 14 infants with cryptogenic West syndrome. Regions of interest (ROIs) for rCBF were placed automatically using an automated ROI analysis software (three-dimensional stereotactic ROI template), and were grouped into 12 segments: callosomarginal, precentral, central, parietal, angular, temporal, posterior cerebral, pericallosal, lenticular nucleus, thalamus, hippocampus, and cerebellum.
