The CT-angiography (CTA) spot sign is a predictor of hematoma expansion (HE). We have previously reported on the use of dynamic CTA (dCTA) to detect spot sign, and to study its formation over the acquisition period. In this study, we report the frequency of dCTA spot sign in acute intracerebral ... Read more >>

<h4>Background</h4>Dynamic CT angiography (dCTA) contrast extravasation, known as the "dynamic spot sign", can predict hematoma expansion (HE) in intracerebral hemorrhage (ICH). Recent reports suggest the phase of spot sign appearance is related to the magnitude of HE. We used dCTA to explore the association between the phase of spot sign ... Read more >>

We reviewed stroke care delivery during the COVID-19 pandemic at our stroke center and provincial telestroke system. We counted referrals to our prevention clinic, code strokes, thrombolysis, endovascular thrombectomies, and activations of a provincial telestroke system from February to April of 2017-2020. In April 2020, there was 28% reduction in ... Read more >>

The Modified Intracerebral Hemorrhage (MICH) score is a simple tool created to provide prognostication in basal ganglia hemorrhages. Current prognostic scores, including the MICH, are based on the assessment of baseline patient characteristics, failing to account for significant developments, such as intraventricular extension and clinical deterioration, which may occur over ...

<h4>Background</h4>Cryptogenic strokes constitute 20 to 30% of ischemic strokes, and most cryptogenic strokes are considered to be embolic and of undetermined source.

<h4>Background and purpose</h4>Hematoma expansion in intracerebral hemorrhage is associated with higher morbidity and mortality. The computed tomography (CT) angiographic spot sign is highly predictive of expansion, but other morphological features of intracerebral hemorrhage such as fluid levels, density heterogeneity, and margin irregularity may also predict expansion, particularly in centres where ...

Diallyl sulfone (DASO2) is a garlic derivative formed during cooking or after ingestion. Bioactivation of DASO2 in murine lung and liver results in formation of an epoxide that inactivates CYP2E1 and significantly decreases cytochrome P450 and heme levels.
