We analyzed the impact of cause, severity, and duration of fever on functional outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). ⋯ Early onset of fever, number of hours with fever, and especially days of fever are associated with poor functional outcome. Conversely, subfebrile load does not influence clinical outcome. These data suggest prolonged fever should be avoided, but subfebrile temperatures may not justify intervention.

Intracranial subarachnoid hemorrhage (SAH) and spinal subdural hematoma (SDH) are rare complications of spine surgery, thought to be precipitated by cerebrospinal fluid (CSF) hypotension in the setting of an intraoperative durotomy or postoperative CSF leak. Considerable clinical variability has been reported, requiring a high level of clinical suspicion in patients with a new, unexplained neurologic deficit after spine surgery. ⋯ We report the first case of simultaneous intracranial SAH and spinal SDH attributable to postoperative CSF hypotension in the setting of a known intraoperative durotomy. Although rare, each of these entities has the potential to precipitate a poor neurologic outcome, which may be mitigated by early recognition and treatment.

Simulation is becoming a more common modality in medical education. The data regarding effectiveness of simulation in critical care neurology education are limited. ⋯ Simulation is an effective means of neurologic education for critical care trainees, with improvement in both medical knowledge and trainee confidence after completion of a three-scenario simulation experience. This course ensures the exposure of critical care trainees to neurologic diseases that are required curricular milestones to successfully complete the fellowship training program.

The antidepressant-like effects of simvastatin on traumatic brain injury (TBI) remain unclear. The present study aimed to investigate the neuroprotective effects of simvastatin and determine whether simvastatin attenuates TBI-induced depression-like behavior and, more specifically, acts as an antineuroinflammatory. ⋯ Intraperitoneal injection of simvastatin attenuated TBI in rats during the acute stage by reducing neuronal apoptosis, microglia, and TNF-α expression, thereby resulting in a reduction of depressive-like behavior. Our results suggest that simvastatin may be a promising treatment for TBI-induced depression-like behavior.
