A method for assessing pain and analgesia in rats and cats is described. The procedure involves subcutaneous injection of dilute formalin into the forepaw, after which the animal's responses are rated according to objective behavioral criteria. The formalin test is a statistically valid technique which has two advantages over other pain tests: (1) little or(More)
Evoked potentials to visually driven cognitive tasks were recorded through depth electrodes placed bilaterally within the amygdala, hippocampus, midtemporal and inferotemporal cortex, and lateral frontal cortex of 6 epileptic patients. Task-related differential response patterns were used to identify the recording sites engaged by specific aspects of visual(More)
A successfully treated case of inversion and herniation of a cerebral hemisphere beneath the falx is reported. This condition resulted from large subdural hematomas as a complication of shunting in advanced hydrocephalus. The subdural collections were evacuated gradually while ventricular cerebrospinal fluid was replenished through the externalized(More)
In 6 patients, depth electrodes revealed differential evoked responses to familiar versus novel faces. These differential responses were obtained in the amygdala, hippocampus, and temporal neocortex but not in the dorsolateral frontal or cingulate cortex. The limbic and temporal structures that differentiated novel from familiar faces did not respond(More)
We compared the pulsatile secretion of luteinizing hormone (LH) between 13 men with clinically and electrographically documented temporal lobe seizures and 8 age-matched controls. Serum for LH measurement was drawn every 15 minutes during 8 hours of EEG telemetry in both groups. The 2 groups did not differ significantly in average mean baseline LH(More)
Visual evoked potentials were recorded in the amygdala, hippocampus, mid- and inferotemporal cortex, orbitofrontal cortex, and lateral frontal cortex of seven epileptic patients while they were engaged in a difficult task requiring the discrimination between repeated and nonrepeated faces. The explicit recognition of previously seen faces was at chance(More)
Craniopharyngioma, a tumor most commonly diagnosed in the young, may occur at any age. The oldest patient known to have histologic documentation of a craniopharyngioma, an 82.5-year-old woman, presented with visual field changes, panhypopituitarism, and mental status changes. This diagnosis should be considered in such patients, because craniopharyngioma is(More)
INTRODUCTION Adherence to surgical safety checklists remains challenging. Our institution demonstrated acceptable rates of checklist utilization but poor adherence to all checkpoints. We hypothesized that stepwise, multifaceted interventions would improve checklist adherence. METHODS From 2011 to 2013, adherence to the 14-point, pre-incision checklist was(More)
