Review Meta AnalysisMatrix metalloproteinase-9: dual role and temporal profile in intracerebral hemorrhage.
Clinical outcome after intracerebral hemorrhage (ICH) remains poor. Recent trials in ICH, focusing on hematoma reduction, have not yielded significant clinical improvement. The modulation of matrix metalloproteinase (MMP)-9 may represent a potential therapeutic target for reducing perihematomal edema (PHE) and improving clinical outcome. ⋯ MMP-9 inhibition represents a potentially effective target for neuroprotection in ICH. However, as a ubiquitous protein, the inhibition of pathologic processes must be balanced against the preservation of neuroprotective angiogenesis. As the opposing roles of MMP-9 may have similar mechanisms, the most important factor may be the timing of MMP-9 inhibition. Further studies are necessary to delineate these mechanisms and their temporal relationship.

Multicenter Study Observational StudyIntravenous nicardipine dosing for blood pressure lowering in acute intracerebral hemorrhage: the Stroke Acute Management with Urgent Risk-factor Assessment and Improvement-Intracerebral Hemorrhage study.
Intravenous nicardipine is commonly used to reduce elevated blood pressure in acute intracerebral hemorrhage (ICH). We determined factors associated with nicardipine dosing and the association of dose with clinical outcomes in hyperacute ICH. ⋯ Nicardipine dose is roughly predictable with sex, age, body weight, and initial SBP in acute ICH. The maximum dose was associated with neurologic deterioration.

Observational StudySubarachnoid extension of hemorrhage is associated with early seizures in primary intracerebral hemorrhage.
Seizures are common in patients with subarachnoid hemorrhage, potentially by inciting cortical irritability. Seizures are also commonly seen after intracerebral hemorrhage (ICH), although the mechanisms and risk factors within that population are not well understood. The objective of this study is to evaluate whether subarachnoid hemorrhage extension (SAHE) is associated with early seizures in patients with primary ICH. ⋯ SAHE is associated with early seizures in patients with primary ICH. Further study is needed to confirm these findings and determine whether modifications to routine care based on the presence of SAHE would be of benefit.

Comparative StudyDoes large vessel occlusion affect clinical outcome in stroke with mild neurologic deficits after intravenous thrombolysis?
Large vessel occlusion (LVO) is associated with poor functional outcome in acute ischemic stroke. Given the uncertainty whether LVO has the same significance in mild and severe stroke, we compared functional outcomes after intravenous thrombolysis, based on severity and LVO. ⋯ LVO is associated with worse functional outcome and mortality in severe stroke after intravenous thrombolysis. Although significant association between LVO and outcome in mild stroke was not found, there were similar effects on outcome and a larger study might well confirm a relationship.

Comparative StudyDo characteristics of dissection differ between the posterior inferior cerebellar artery and the vertebral artery?
The purpose of this study was to clarify the features of posterior inferior cerebellar artery (PICA) dissection. ⋯ Patients with PICA dissection suffered from subarachnoid hemorrhage more frequently than those with VA dissection. PICA dissection was treated with surgical intervention, whereas VA dissection was treated conservatively.
