Randomized Controlled Trial
Cognitive and neurophysiological outcome of cardiac arrest survivors treated with therapeutic hypothermia.
Cognitive deficits are common in survivors of cardiac arrest (CA). The aim of this study was to examine the effect of therapeutic hypothermia after CA on cognitive functioning and neurophysiological outcome. ⋯ The use of therapeutic hypothermia was not associated with cognitive decline or neurophysiological deficits after out-of-hospital CA.

The purpose of this study was to describe prognostic factors for outcome in a large series of patients undergoing neurosurgical clipping of aneurysms after subarachnoid hemorrhage (SAH). ⋯ Although most prognostic factors for outcome after SAH are present on admission and are not modifiable, a substantial contribution to outcome is made by factors developing after admission and which may be more easily influenced by treatment.

In the first 3 months after acute ischemic stroke, 2% to 6% of patients die from cardiac causes. This may reflect preexisting cardiac disease, cardiac dysfunction related to the acute neurohumoral and autonomic stress response to stroke, or both. Delineation of a high-risk group could facilitate prevention strategies. We aimed to describe the temporal profile of cardiac risk after stroke and develop a predictive model of serious cardiac adverse events (SCAEs) using baseline variables. ⋯ Serious cardiac events are common in the acute period after stroke. Patients at highest risk are identifiable and may benefit from more aggressive strategies to improve survival.

Letter Randomized Controlled Trial
A randomized controlled trial of hydrocortisone against hyponatremia in patients with aneurysmal subarachnoid hemorrhage.
Hyponatremia is common after aneurysmal subarachnoid hemorrhage (SAH). It is caused by natriuresis, which induces osmotic diuresis and decreases blood volume, contributing to symptomatic cerebral vasospasm (SCV). Hypervolemic therapy to prevent SCV will not be efficient under this condition. We conducted a randomized controlled trial to assess the efficacy of hydrocortisone, which promotes sodium retention in the kidneys. ⋯ Hydrocortisone overcame excess natriuresis and prevented hyponatremia. Although there was no difference in outcome, hydrocortisone supported efficient hypervolemic therapy.

Tandem internal carotid and middle cerebral artery occlusion independently predicts poor outcome after intravenous thrombolysis. Recanalization of internal carotid artery dissection by stent-assisted angioplasty has recently been proposed when anticoagulation fails to prevent a new ischemic event. We recently reported a case of tandem internal carotid and middle cerebral artery occlusion with dissection of the internal carotid artery successfully treated with endovascular stent-assisted thrombolysis. ⋯ Endovascular stent-assisted thrombolysis is a promising treatment in tandem internal carotid and middle cerebral artery occlusion due to internal carotid artery dissection and compares favorably with intravenous rtPA.
