Time course and risk factors for myocardial dysfunction after aneurysmal subarachnoid hemorrhage.
Myocardial wall motion abnormalities (WMAs) are independent risk factors for a poor outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). ⋯ NCT00123695.

The importance of underlying atherosclerotic intracranial artery stenosis (ICAS) in hyperacute stroke patients who receive endovascular therapy remains unknown. ⋯ Emergent intracranial angioplasty with or without stenting is safe and feasible and yields a high rate of revascularization and favorable outcome in patients with hyperacute stroke and underlying ICAS. Patients with underlying ICAS have less severe infarctions at presentation and higher successful revascularization after multimodal endovascular therapy in the setting of hyperacute stroke compared with those with other stroke subtypes.

Clinical outcome of children with suspected shunt malfunction evaluated in the emergency department.
Patients with cerebrospinal fluid shunts frequently present to the emergency department (ED) with suspected shunt malfunction. The outcome of those patients who were discharged from ED when shunt malfunction was deemed unlikely has not been previously documented. ⋯ Children with cerebrospinal fluid shunts are often evaluated in the ED. Discharge from the ED, when suspicion for shunt malfunction is low, is an appropriate practice.

Finding the optimal location for the implantation of the electrode in deep brain stimulation (DBS) surgery is crucial for maximizing the therapeutic benefit to the patient. Such targeting is challenging for several reasons, including anatomic variability between patients as well as the lack of consensus about the location of the optimal target. ⋯ Fully automatic targeting based on nonrigid image registration with the use of the CranialVault atlas is as accurate and more precise than popular manual methods for STN-DBS.
