We reviewed the EEG, clinical manifestations, computed tomography (CT) and magnetic resonance imaging (MRI) scans of 39 patients with periodic lateralized epileptiform discharges (PLEDs) or bilateral periodic lateralized epileptiform discharges (BIPLEDs) to determine the role of structural lesions (SL) and metabolic abnormalities (MA) in their pathogenesis.… (More)
We analyzed the results of neuroimaging studies in patients with periodic lateralized epileptiform discharges (PLEDs) or bilateral independent periodic lateralized epileptiform discharges (BIPLEDs) for localization of lesions in gray or white matter to determine if "cortical isolation" is a critical mechanism in the pathogenesis of this phenomena. We… (More)
Three women presenting with toxemia of pregnancy revealed reversible increased signal intensity on T2-weighted images by MRI. Overall, neuroradiologic techniques, with MRI the most sensitive, help elucidate the pathophysiology and facilitate the diagnosis in this condition.
A case of Möbius syndrome was associated with transposition of the aorta and pulmonary artery, as well as acheiria. This combination of anomalies supports the hypothesis that Möbius syndrome is caused by an intrapartum insult during the fourth to seventh week of gestation and is consistent with the vascular theory of embryopathogenesis.
BACKGROUND Postpartum cerebral angiopathy is associated with the use of of ergot alkaloids. The exact mechanism is unclear but may be related to their sympathomimetic properties, as evidenced in patients already on other ergot derivatives who deteriorated only after taking additional sympathomimetic drugs. We postulate that sympathomimetic agents,… (More)
A patient undergoing intraoperative median nerve somatosensory evoked potential (MSEP) and brain-stem auditory evoked response (BAER) monitoring showed changes during basilar artery aneurysm clipping. There was loss of the BAER wave V, with preservation of waves I and III. Simultaneously, there also was loss of the MSEP N20 potential, with preservation of… (More)
Nerve conduction velocity studies were done in median, ulnar, and peroneal nerves, one time each in 46 patients who had been on chronic peritoneal dialysis or hemodialysis for varying lengths of time. Only six patients had normal findings; 37 had peripheral polyneuropathy (15 had isolated polyneuropathy; 22 had median nerve dysfunction in addition); 16 had… (More)
A 60-year-old white man presented with aphasia, seizures, paraparesis, and incontinence. His serologic and hematologic profiles were unremarkable. His cerebrospinal fluid showed pleocytosis, increased daily central nervous system IgG synthesis, increased myelin basic protein, and negative cytology and cultures. Cerebral computed tomography exhibited… (More)
A review of clinical data from 18 pediatric patients with periodic lateralized epileptiform discharges and bilateral independent periodic lateralized epileptiform discharges (PLEDs and BIPLEDs) showed 2 with chronic neurologic illness, 6 with a history of prior seizures, 14 with depressed sensorium at the time of EEG, 5 deaths, and 8 of 13 survivors with… (More)
