Obtaining viable informed consent from stroke patients for participation in clinical trials of acute stroke therapies is often problematic because of patients' neurological deficits. Furthermore, obtaining permission from surrogates is often not possible or not legally permissible. ⋯ Acute stroke researchers should consider conducting clinical trials with an exception from the informed consent requirement permitted by this law.

Early assessments of dysphagia and aspiration risk in acute stroke patients.
Dysphagia is common after stroke and is a marker of poor prognosis. Early identification is important. This article reviews the merits and limitations of various assessment methods available to clinicians. ⋯ Although bedside tests remain an important early screening tool for dysphagia and aspiration risk, further refinements are needed to improve their accuracy.

Carotid angioplasty and stenting (CAS) is increasingly being used for treatment of symptomatic and asymptomatic carotid artery disease (CAD). To evaluate the efficacy of cerebral protection devices in preventing thromboembolic complications during CAS, we conducted a systematic review of studies reporting on the incidence of minor stroke, major stroke, or death within 30 days after CAS. ⋯ On the basis of this early analysis of single-center studies, the use of cerebral protection devices appears to reduce thromboembolic complications during CAS. These technical aspects should be taken into account before the initiation of further randomized trials comparing CAS with carotid endarterectomy.
