Neurocritical care
-
Neurocritical care is a new subspecialty field in medicine that intersects with many of the neuroscience and critical care specialties, and continues to evolve in its scope of practice and practitioners. The objective of this study was to assess the perceived need for and roles of neurocritical care intensivists and neurointensive care units among physicians involved with intensive care and the neurosciences. ⋯ Broad level of support exists among the survey respondents (mostly neurologists and intensivists) for the establishment of neurological critical care units. Since neurology remains the predominant career path from which to draw neurointensivists, there may be a role for more comprehensive neurointensive care training within neurology residencies or an alternative training track for interested residents.

Comparative Study
Phenytoin, levetiracetam, and pregabalin in the acute management of refractory status epilepticus in patients with brain tumors.
There were nearly 700,000 patients in the United States in 2010 living with brain tumor diagnoses. The incidence of seizures in this population is as high as 70% and is historically difficult to control. Approximately 30-40% of brain tumors patients who present with status epilepticus (SE) will not respond to typical therapy consisting of benzodiazepines and phenytoin (PHT), resulting in patients with refractory status epilepticus (RSE). RSE is usually treated with anesthetic doses of propofol or midazolam infusions. This therapy can have significant risk, particularly in patients with cancer. ⋯ Our study suggests that the administration of PHT, LEV, and PGB in brain tumor patients with RSE is safe and highly effective.

Current guidelines for management of critically ill stroke patients suggest that treatment in a neurocritical care unit (NCCU) and/or by a neurointensivist (NI) may be beneficial, but the contribution of each to outcome is unknown. The relative impact of a NCCU versus NI on short- and long-term outcomes in patients with acute ischemic stroke (AIS), intracerebral hemorrhage (ICH), and aneurysmal subarachnoid hemorrhage (SAH) was assessed. ⋯ Presence of an NI was associated with improved clinical outcomes. This effect was more evident in patients with SAH. Patients with ICH tend to have poor outcomes regardless of the presence of a NCCU or a NI.

Case Reports
Intracranial aneurysm with concomitant rupture of an undiagnosed visceral artery aneurysm.
Concomitant intracranial and visceral artery aneurysms are a rare occurrence. We report the case of a patient who underwent surgical repair of a ruptured intracranial aneurysm but subsequently experienced a ruptured hepatic artery aneurysm in the immediate postoperative period. ⋯ Prior to this report, there have only been 2 documented cases of concomitant intracranial and visceral artery aneurysms. These reports serve to remind the clinician that intracranial aneurysms may be only part of a systemic pathology, which should be taken into account when unexpected complications arise postoperatively.

Therapeutic hypothermia (TH) improves outcomes in comatose patients resuscitated from cardiac arrest. However, nonconvulsive status epilepticus (NCSE) may cause persistent coma. The frequency and timing of NCSE after cardiac arrest is unknown. ⋯ NCSE is common in comatose post-cardiac arrest subjects receiving TH. Most seizures occur within the first 8 h of cEEG recording and within the first 12 h after resuscitation from cardiac arrest. Outcomes are poor in those who experience NCSE.
