Cardioembolic stroke secondary to Lambl's excrescence on the aortic valve: a case report.

We report a patient who presented with aphasia and was found to have an embolic cerebral infarction secondary to LE. LE is a rare source of cardioembolic stroke.

Association between hyperoxia and mortality after stroke: a multicenter cohort study.

Objective: To test the hypothesis that hyperoxia was associated with higher in-hospital mortality in ventilated stroke patients admitted to the ICU.

Design: Retrospective multicenter cohort study.

Setting: Primary admissions of ventilated stroke patients with acute ischemic stroke, subarachnoid hemorrhage, and intracerebral hemorrhage who had arterial blood gases within 24 hours of admission to the ICU at 84 U.

Effectiveness of Factor IX complex concentrate in reversing warfarin associated coagulopathy for intracerebral hemorrhage.

Introduction: The objective of this study is to show the effectiveness of Factor IX complex concentrate (FIXCC) for rapid reversal of an elevated International Normalized Ratio (INR) in patients with anticoagulation-associated intracerebral hemorrhage (AAICH).

Methods: We, retrospectively, analyzed the clinical data of 19 patients with the diagnosis of AAICH from January 2005 to May 2006. A comparison was made among patients treated with FFP and Vit.

Beyond intravenous thrombolysis.

The National Institute of Neurological Disorders and Stroke trial of recombinant tissue plasminogen activator has been considered a landmark study in the acute treatment of ischemic stroke. Unfortunately, only a small percentage of all ischemic stroke patients presents to the hospital in time to receive the drug. Moreover, the recannalization rate of a major artery occlusion, such as the proximal middle cerebral artery or top of the internal carotid artery occlusion, after intravenous (IV) thrombolytic therapy has been disappointingly low.

Perfusion-CT assessment of infarct core and penumbra: receiver operating characteristic curve analysis in 130 patients suspected of acute hemispheric stroke.

Background And Purpose: Different definitions have been proposed to define the ischemic penumbra from perfusion-CT (PCT) data, based on parameters and thresholds tested only in small pilot studies. The purpose of this study was to perform a systematic evaluation of all PCT parameters (cerebral blood flow, volume [CBV], mean transit time [MTT], time-to-peak) in a large series of acute stroke patients, to determine which (combination of) parameters most accurately predicts infarct and penumbra.

Methods: One hundred and thirty patients with symptoms suggesting hemispheric stroke < or =12 hours from onset were enrolled in a prospective multicenter trial.

Light therapy for seasonal affective disorder with blue narrow-band light-emitting diodes (LEDs).

Background: While light has proven an effective treatment for Seasonal Affective Disorder (SAD), an optimal wavelength combination has not been determined. Short wavelength light (blue) has demonstrated potency as a stimulus for acute melatonin suppression and circadian phase shifting.

Methods: This study tested the efficacy of short wavelength light therapy for SAD.
