The role of admission timing in the outcome of intracerebral hemorrhage patients at a specialized stroke center.

Introduction: Admission at 'off times' has been suggested to result in increased risk of poor outcome. The utilization of high volume centers may be a potential remedy to this variability in care.

Objective: To assess the ability of a high volume center to mitigate variability in care due to timing of admission in a post hoc analysis of an observational study.

Delay in surgical treatment of patients with hilar cholangiocarcinoma: does time impact outcomes?

Background: Substantial time elapses before patients with hilar cholangiocarcinoma (HCC) receive surgical treatment because of time-consuming preoperative staging and other interventions, including biliary drainage and portal vein embolization. Prolonged times potentially lead to unresectability and the formation of metastases, yet these issues have not been investigated previously in HCC. This study aimed to evaluate the time between onset of symptoms and the provision of ultimate treatment in patients with HCC and the impact of the length of time on outcomes.

Decompressive hemicraniectomy without clot evacuation in dominant-sided intracerebral hemorrhage with ICP crisis.

Object: Large intracerebral hemorrhage (ICH), compounded by perihematomal edema, can produce severe elevations of intracranial pressure (ICP). Decompressive hemicraniectomy (DHC) with or without clot evacuation has been considered a part of the armamentarium of treatment options for these patients. The authors sought to assess the preliminary utility of DHC without evacuation for ICH in patients with supratentorial, dominant-sided lesions.

Alpha-7 nicotinic acetylcholine receptor agonists in intracerebral hemorrhage: an evaluation of the current evidence for a novel therapeutic agent.

Intracerebral hemorrhage (ICH) is the most deadly and least treatable subtype of stroke, and at the present time there are no evidence-based therapeutic interventions for patients with this disease. Secondary injury mechanisms are known to cause substantial rates of morbidity and mortality following ICH, and the inflammatory cascade is a major contributor to this post-ICH secondary injury. The alpha-7 nicotinic acetylcholine receptor (α7-nAChR) agonists have a well-established antiinflammatory effect and have been shown to attenuate perihematomal edema volume and to improve functional outcome in experimental ICH.

The role of advanced neuroimaging in intracerebral hemorrhage.

In this report, the authors sought to summarize existing literature to provide an overview of the currently available techniques and to critically assess the evidence for or against their application in intracerebral hemorrhage (ICH) for management, prognostication, and research. Functional imaging in ICH represents a potential major step forward in the ability of physicians to assess patients suffering from this devastating illness due to the advantages over standing imaging modalities focused on general tissue structure alone, but its use is highly controversial due to the relative paucity of literature and the lack of consolidation of the predominantly small data sets that are currently in existence. Current data support that diffusion tensor imaging and tractography, diffusion-perfusion weighted MRI techniques, and functional MRI all possess major potential in the areas of highlighting motor deficits, motor recovery, and network reorganization.
