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.

Elevated red blood cell distribution width (RDW) has been associated with thrombotic disorders including myocardial infarction, venous thromboembolism, and ischemic stroke, independent of other inflammatory and coagulation biomarkers. The purpose of this study was to determine whether elevated RDW is associated with cerebral infarction and poor outcome after aneurysmal subarachnoid hemorrhage (aSAH). ⋯ RDW elevation is associated with cerebral infarction and poor outcome after aSAH. Further evaluation of this association is warranted as it may shed light on mechanistic relations between anemia, inflammation, and thrombosis after aSAH.

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 American Academy of Neurology (AAN) has established a core curriculum of topics for residency training in neurocritical care. At present there is limited data evaluating neurology residency education within the neurological intensive care unit. This study evaluates learner concerns with the neurological intensive care unit. ⋯ There is significant learner concern regarding education within the neurointensive care unit. Although there are educational guidelines and focused neurocritical care educational materials, these alone do not satisfy residents' educational needs. This study demonstrates the need for educational changes, but it does not assess best strategies nor curricular content.

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.
