ReviewTelemedicine or telephone consultation in patients with acute stroke.
The advantages of telephone consultations for patients with acute stroke syndromes are history of use, simplicity, availability, portability, short consultation time, and facile implementation. The favorable aspects of telemedicine consultations are high accuracy, reliability, efficacy, and effectiveness, the growing technological sophistication of the offerings and features, and the high grade of recommendation. ⋯ With recent advances in one-way/two-way video and teleradiology features adapted to Smartphones, the dividing line between "telephone" and "telemedicine" consultations for acute stroke is indistinct. Telestroke providers prefer a figurative "tool belt" of technologies available to adapt to individual consultation requirements.

ReviewTreatment of carotid artery disease: endarterectomy or angioplasty?
The management of carotid stenosis has enjoyed renewed interest in the neurological community in recent years due to the advent of endovascular approaches. In concert, progress in medical treatment of these patients has rekindled the debate regarding the best management of carotid stenosis overall, both for symptomatic and asymptomatic disease. ⋯ For patients with asymptomatic carotid stenosis, intensive medical management has evolved significantly over the past decade to decrease the risk of ischemic stroke to match surgical intervention under most circumstances. This review will examine the supporting evidence for each intervention, and discuss the recent advances in medical and endovascular therapy that provide the data for a new era in clinical decision making.

ReviewImplications of pharmacogenetic testing for patients taking warfarin or clopidogrel.
Our knowledge of the pharmacogenetics of warfarin and clopidogrel continues to expand as we learn more about the individual genetic variations that contribute to the drugs' efficacy and toxicity. We aim to review the recent developments in the field and discuss the clinical implications for the treatment of ischemic stroke patients. Despite recent advances, there is still insufficient data to suggest that routine genetic testing improves outcomes in patients treated with warfarin or clopidogrel for prevention of stroke.

Before the use of hypothermia as a treatment for comatose post-cardiac arrest patients, several prognostic variables were widely accepted as reliable and valid for the prediction of poor outcome. Recent studies using hypothermia have reported on patients with recovery of consciousness in spite of absent or extensor motor responses after 3 days, absent bilateral cortical N20 responses after 24 h, serum neuron-specific enolase levels greater than 33 μg/L, and early myoclonus status epilepticus. ⋯ Recent developments in brain imaging may provide additional objective prognostic information and deserve further study. Pending the results of future validation studies in patients treated with hypothermia, we recommend that irreversible management decisions not be made based on a single prognostic parameter, and, if there is uncertainty, these decisions be delayed for several days to allow for repeated testing.
