BACKGROUND Traumatic brain injury (TBI) is a major cause of death and disability worldwide. Progesterone has been shown to improve neurologic outcome in multiple experimental models and two early-phase trials involving patients with TBI. METHODS We conducted a double-blind, multicenter clinical trial in which patients with severe, moderate-to-severe, or(More)
BACKGROUND Early termination of prolonged seizures with intravenous administration of benzodiazepines improves outcomes. For faster and more reliable administration, paramedics increasingly use an intramuscular route. METHODS This double-blind, randomized, noninferiority trial compared the efficacy of intramuscular midazolam with that of intravenous(More)
PURPOSE To determine the relationship between the hyperdense middle cerebral artery sign (HMCAS) and neurologic deficit, as evidenced by the National Institutes of Health (NIH) stroke scale score, and to determine the relationship of the HMCAS and the NIH stroke scale score to arteriographic findings after thrombolytic therapy. METHODS Fifty-five patients(More)
American Society of Neuroradiology " Neuroimaging (NI) can help determine whether seizures result from a structural abnormality of the brain or its surroundings. NI can be a useful tool in a variety of clinical settings in the evaluation of patients who present with seizures. Patients may report seizure-related symptoms to their primary care provider,(More)
BACKGROUND In animal models of ischaemic stroke, 25% albumin reduced brain infarction and improved neurobehavioural outcome. In a pilot clinical trial, albumin doses as high as 2 g/kg were safely tolerated. We aimed to assess whether albumin given within 5 h of the onset of acute ischaemic stroke increased the proportion of patients with a favourable(More)
The telemedicine intervention in chronic disease management promises to involve patients in their own care, provides continuous monitoring by their healthcare providers, identifies early symptoms, and responds promptly to exacerbations in their illnesses. This review set out to establish the evidence from the available literature on the impact of(More)
The authors evaluate eight patients with intracerebral hemorrhage (ICH) who underwent computerized tomography (CT) within 2 1/2 hours after symptom onset and then again several hours later. The second CT scan was performed within 12 hours after onset for seven of the patients and 100 hours after onset for the eighth patient. In four patients, the second CT(More)
BACKGROUND In an adaptive clinical trial (ACT), key trial characteristics may be altered during the course of the trial according to predefined rules in response to information that accumulates within the trial itself. In addition to having distinguishing scientific features, adaptive trials also may involve ethical considerations that differ from more(More)
The hyperdense middle cerebral artery sign (HMCAS) is recognized as a CT finding that indicates thrombus or embolus within the middle cerebral artery. The incidence and significance of this sign are quantitatively evaluated in 50 patients entered into experimental drug studies for treatment of cerebral infarction.
