The Sunnybrook Facial Grading System (SFGS) is one of the most employed scales to assess the severity of facial palsy. The aim of our study was to produce an Italian version of the SFGS and of its explanatory criteria, and to test their measurement properties when employed by Italian physicians. A multidisciplinary committee translated and adapted the scale and its criteria into Italian. ⋯ The scores given by the novice physicians were comparable with the scores given by the expert physicians. Our study suggests that the Italian version of the SFGS has excellent internal consistency and reproducibility, comparable to the original scale. Our study confirms in an independent case record the high measurement properties of SFGS and provides the first validated Italian scale for the assessment of facial palsy.

Early recognition of stroke symptoms and activation of emergency medical service (EMS) positively affects prognosis after a stroke. To assess stroke awareness among stroke patients and medical personnel in the catchment area of Verona Hospital and how it affects stroke care, we prospectively studied timing of acute stroke care in relation to patients' characteristics. Patients admitted to Medical Departments of Verona University Hospital between January 1st and December 31st 2009 with a diagnosis of TIA or stroke were enrolled. ⋯ Of 578 patients providing complete information, 60 % arrived to the emergency department with the EMS (EMS+ group), while 40 % arrived on their own (EMS-). EMS+ group was older than EMS- (mean age 76.2, SD 13.2, vs. 72.3, SD 13, respectively), displayed more severe symptoms (mRS 4 vs. 2) and shorter time interval between symptoms onset and hospital arrival, hospital arrival and CT scan, ECG, laboratory tests and neurological evaluation (p < 0.0001); 22 % of the EMS+ patients were stroke recurrences versus 29 % of the EMS- (p = 0.058); 85 % of thrombolised patients were EMS+. We conclude that there is a lack of awareness of stroke symptoms and risks of recurrence even among patients who already had a stroke and among medical personnel.

Local hypothermia induced by intra-arterial infusion of cold saline reduces brain injury in ischemic stroke. Administration of magnesium sulfate through the internal carotid artery is also known to reduce ischemic brain damage. The neuroprotective effects of combination therapy with local endovascular hypothermia and intra-carotid magnesium sulfate infusion has not been evaluated. ⋯ Furthermore, the rats given a local cold magnesium infusion had the best neurological outcome. Local normothermic infusion failed to improve ischemic brain damage. These data suggest that local hypothermia induced by intra-carotid administration of cold magnesium is more effective in reducing acute ischemic damage than infusion of cold saline alone.
