Seizure patterns and other clinical features were analyzed in 55 epileptic patients with electrographic evidence of exclusive or predominant occipital involvement. Few statistically significant differences in clinical or ictal patterns were found between subjects with purely focal occipital involvement and those with temporal and temporo-parietal spread or(More)
Four patients with seizures of presumed temporal lobe origin are presented in whom a definite focal ictal onset in the orbitofrontal cortex was revealed during recording, either by chronically implanted electrodes or ECoG. In three cases automatisms occurred concomitantly with orbitofrontal activation without spread of paroxysmal activity into the temporal(More)
Fifty-five patients with intractable partial seizures whose on-medication EEGs demonstrated either predominantly focal epileptiform lesions or absence of paroxysmal activity, were studied, and the effect of withdrawing all anticonvulsive drugs on their EEGs was observed. Four types of response were encountered: (1) no effect (20%); (2) specific (focal)(More)
Four prolonged episodes of partial complex status epilepticus were observed in a teenaged girl. During each there was an "ictal" phase, in which her mental state frequently fluctuated between mildly clouded consciousness and almost total unresponsiveness; once, she was also blind during this phase of impaired consciousness. With therapy, the periods of(More)
This study is based on 28 patients with intractable seizures in whom exclusively extratemporal or a combination of temporal and extratemporal electrodes were chronically implanted for the localization of the epileptogenic process and possible surgical treatment. Clinical and electrographic data are briefly summarized, the indications for the use of(More)
A case of a suprasellar granular cell tumor, approximately 1.5 cm in diameter, in a 68-year-old woman is described. Diagnosis was established postoperatively by histopathological examination of the tumor tissue. The preoperative computed tomographic scan revealed a slightly hyperdense suprasellar mass with strong contrast enhancement. There was no evidence(More)
A 20-year-old man suffering from Crohn's disease developed coma and generalized seizures following ileocecal resection. During postoperative parenteral feeding he received xylitol in an unusually high concentration. CT examinations a few days before death showed intense hypodensity and swelling of brainstem and basal ganglia and increasing triventricular(More)
Intracranial hemorrhage and decreased density of the cerebral parenchyma were the major findings on CT of 150 full term newborns in the first week of life. Clinically silent hemorrhage was rare. All neonates with severe intracranial bleeding had neurological abnormalities. A correlation was not found between hemorrhage and the mode of delivery. The site of(More)
