OBJECTIVE Surgical resection of the temporal lobe is an effective treatment for medically intractable temporal lobe epilepsy, but can cause memory impairment. Deep brain stimulation in epilepsy has targeted gray matter structures using high frequencies, but achieved limited success. We tested the hypothesis that low-frequency stimulation of the fornix(More)
OBJECTIVE Reducing health and economic burdens from diagnostic delay of psychogenic nonepileptic seizures (PNES) requires prompt referral for video electroencephalography (VEEG) monitoring, the diagnostic gold standard. Practitioners make VEEG referrals when semiology suggests PNES, although few semiological signs are supported by well-designed studies, and(More)
Percutaneous endoscopic gastrostomy (PEG) tubes are commonly needed for early nutrition in patients with acute ischemic stroke. We evaluated the relationship between the NIH Stroke Scale (NIHSS) score and the need for PEG tube placement. Patients with acute ischemic stroke were included in this study. We collected information on patient demographics, stroke(More)
BACKGROUND Delay in distinguishing psychogenic nonepileptic seizures (PNES) from epilepsy may result in significant health and economic burdens. Screening tools are needed to facilitate earlier identification of patients with PNES, thereby maximizing cost-effective use of video electroencephalography (VEEG), the expensive gold standard for differentiating(More)
Coexistence of cortical dysplasias (CD) with cavernomas has rarely been reported. We reviewed our surgical specimens from patients who underwent surgery for pharmacoresistant epilepsy between 2003 and 2008, and identified seven cases with cavernoma, of whom two had overlying CD. In addition, each of these patients had a third form of a potentially(More)
The diaphragm pacing system (DPS) is a minimally invasive alternative to mechanical ventilation in patients with quadriplegia due to cervical myelopathy primarily caused by high cervical spinal cord injury. We evaluated 36 patients, 29 of whom had traumatic spinal cord injury, two who had a history of remote meningitis and demyelinating disease, and five(More)
PURPOSE Diagnostic delay in distinguishing psychogenic nonepileptic seizures (PNES) from epileptic seizures may result in unnecessary therapeutic interventions and higher health care costs. Previous studies demonstrated that video-recorded eye closure is associated with PNES. The present study prospectively assessed whether observer or self-report of eye(More)
OBJECTIVE To evaluate in-patient mortality and predictors of death associated with convulsive status epilepticus (SE) in a large, multi-center, pediatric cohort. PATIENTS AND METHODS We identified our cohort from the KID Inpatient Database for the years 1997, 2000, 2003 and 2006. We queried the database for convulsive SE, associated diagnoses, and for(More)
UNLABELLED Carefully selected pediatric patients undergo hemispherectomy (HS) for treatment of refractory epilepsy. HS is associated with a mortality rate of 0-6.6% across studies, mostly due to acute hemorrhage. The purpose of this study was to evaluate in-hospital mortality and predictors of the need for blood transfusion during HS in a large, nationwide(More)
BACKGROUND The safety of controlled hypotension during arthroscopic shoulder procedures with the patient in the beach-chair position is controversial. Current practice for the management of intraoperative blood pressure is derived from expert opinion among anesthesiologists, but there is a paucity of clinical data validating their practice. The purpose of(More)
