چکیده
Background and Purpose Although iron-mediated mechanisms are important in experimental brain injury after carotid occlusion, their clinical role in acute ischemic stroke has not been determined. We evaluated the influence of iron stores, measured as serum ferritin, on the outcome of acute cerebral infarct. Methods Admission and fasting glycemia, glycosylated hemoglobin, serum cortisol, serum ferritin, and 24-hour urinary free cortisol levels were measured on the first day of hospitalization in 67 patients admitted with an acute ischemic stroke of less than 24 hours' duration. Patients were classified into two groups according to their Canadian Stroke Scale (CSS) score on day 30; good outcome group (alive and CSS score >7 points) and poor outcome group (dead or CSS score <, 1 points). Results Thirty-three patients (49%) had good outcome and 34 (51%) poor outcome. Fasting glycemia (P=.001), serum cortisol (P<.001), and urinary free cortisol (P=.OO1) but not

The Relation between GABA and L-Arginine Levels with some Stroke Risk Factors in Acute Ischemic Stroke Patients
Changes in extra and intracellular neurotransmitter amino acids concentration in the early stage of acute cerebral ischemia have been reported. In this the study, serum level of gamma aminobutyric acid (GABA) and L-Arginine in acute ischemic stroke patients was assessed. 60 patients with acute ischemic stroke and sixthy healthy volunteers as a control group were assessed. Serum GABA was measure...
متن کاملO10: Thrombo-Inflammation in Acute Ischemic Stroke
Ischemic stroke has been classified as a merely thrombotic disease, so the main goal of its treatment is the recanalization of the occluded vasculature. However, despite fast restoration of blood circulation, progressive stroke still develops in many patients, which has led to the concept of reperfusion injury. The underlying mechanism is only partly known. Though, it is accepted now, tha...
متن کاملSilent subcortical brain infarction
Introduction: The silent brain lesions detected by MRI were fairly common not only in first-ever stroke but also in normal elderly subjects. Some recent studies show the possible role of silent sub-cortical brain infarction in ischemic stroke. The aim of this study was to evaluate the frequency of silent sub-cortical brain infarction in acute first-ever ischemic stroke. Methods: In this descrip...
متن کاملdysphagia in acute ischemic stroke
Introduction: Swallowing dysfunction complicates acute strokes in 25-32% of cases and directly affects patientschr('39') prognosis and recovery. Dysphagia complicates the course of acute strokes through its potential of the development of chest infection, nutritional problems, and dehydration. Dysphagia is also an independent predictor of respiratory morbidity and mortality in acute stroke. In...
متن کاملP 149: Effect of Glycoprotein IIb/IIIa Inhibition on Acute Ischemic Stroke Injuries
Ischemic stroke accounts for about 87 percent of all cases. It occurs as a result of an obstruction within a vessel of the brain and sudden loss of blood circulation to the corresponding area resulting in the loss of brain function. It is caused by thrombotic or embolic occlusion of an artery and is more common than hemorrhagic stroke. We know that most of the injuries after an acute ischemic s...

Myxoma may cause systemic embolization and frequently presents as ischemic stroke. There has been debates whether it is safe to use recombinant tissue plasminogen activator (rt-PA) in patients with cardiac myxoma who are presented with ischemic stroke at emergency department. we describe a young case of atrial myxoma with initial presentation of acute cerebral infarction symptoms who was treate...
