Geometry of saccular cerebral aneurysms not associated with a branch vessel.
Saccular cerebral aneurysms located at nonbranching sites are uncommon. Their distribution, morphological features, and presence of a branch vessel or a tiny perforator(s) separate from the aneurysm neck were investigated. ⋯ Saccular aneurysms occurring at nonbranching sites are uncommon. Their geometry is particularly favorable for flow directed stents and is most amenable to aneurysms located on large-diameter conducting vessels such as the internal carotid, vertebral, and vertebrobasilar vessels. Smaller parent arteries harboring this type of aneurysm will require new technology to maintain patency of these more distal vessels. If endovascular techniques cannot achieve aneurysm sac obliteration, then open craniotomy and aneurysm clipping will provide a satisfactory alternative.

Executive function and diffusion in frontal white matter of adults with moyamoya disease.
Cognitive impairment is a frequent complication of moyamoya disease (MMD) in adults. Chronic hypoperfusion in frontal lobes can lead to subtle brain injury, resulting in cognitive dysfunctions. Apparent diffusion coefficient (ADC) in normal-appearing white matter on conventional magnetic resonance imaging correlates with cerebral hemodynamics in the frontal lobe. ⋯ The association of ADC with executive function might suggest that ADC is useful in screening for executive dysfunction during follow-up in the outpatient setting.

Case ReportsSubarachnoid hemorrhage after resuscitation from out-of-hospital cardiac arrest.
This study was undertaken to retrospectively investigate clinical features of subarachnoid hemorrhage (SAH) with cardiopulmonary arrest in patients achieving return of spontaneous circulation (ROSC) in order to explore the possibility of long-term survival. ⋯ Cardiac arrest caused by SAH is a disease state with a grave prognosis, but there is the possibility of a good survival outcome when the administration of a small dose of adrenaline results in the rapid recovery of brainstem reflexes.

Speech-language pathologist-led fiberoptic endoscopic evaluation of swallowing: functional outcomes for patients after stroke.
Dysphagia is a common complication after stroke and is associated with the development of pneumonia. Early detection of dysphagia and specifically aspiration is, therefore, critical in the prevention of pneumonia. Fiberoptic endoscopic evaluation of swallowing (FEES) is a safe bedside instrumental tool for detecting dysphagia and aspiration and, therefore, has the potential to inform dysphagia management. This study investigated the clinical utility of a speech-language pathologist-led FEES service on functional outcomes for patients after acute stroke. ⋯ When used selectively, FEES services have potential for improving functional outcomes for patients after stroke.

Comparative StudyThrombolysis for acute ischemic stroke: do patients treated out of hours have a worse outcome?
Previous studies on the impact of nonworking hours (NWH) have produced conflicting results. We aimed to compare the time to treatment with thrombolysis between NWH and working hours (WH) at an Australian comprehensive stroke center. ⋯ Our study showed that the "NWH effect" increased the door-to-needle time. The patients treated out of hours did not have a worse outcome.
