Eclampsia is a poorly understood disorder characterized by seizures or unexplained coma in setting of gestational hypertension. Its neurological manifestations are varied and are an important cause of the morbidity and mortality associated. We present a comprehensive prospective study of forty women recruited over four years describing neurological symptoms(More)
OBJECTIVE To utilize diffusion tensor tractography and evaluate the integrity of the corticospinal tract in children with unilateral Sturge-Weber syndrome (SWS). METHODS Sixteen children (age: 1.5-12.3 years) with SWS involving one hemisphere and varying degrees of motor deficit, underwent magnetic resonance imaging (MRI) as part of a prospective clinical(More)
BACKGROUND AND PURPOSE Timely intervention in young stroke patients minimizes long term disability. We hypothesized that arrival to the emergency department by ambulance would be associated with increased rate of stroke intervention with intravenous t-PA or intra arterial procedures. METHODS Charts of 77 patients aged 15-49 years diagnosed with ischemic(More)
BACKGROUND We sought to examine whether gender-based differences in acute stroke care occur in both Joint Commission (JC) certified and noncertified hospitals. METHODS 602 charts of patients with ischemic stroke were reviewed from five JC certified and five noncertified hospitals for gender differences in the prehospital factors, emergency department(More)
OBJECTIVES The misdiagnosis of acute ischemic stroke in young adults is a significant problem since patients may have many decades of potential disability. Also, proven therapies for acute stroke may not be administered if there is an initial misdiagnosis. We assessed the hypothesis that early use of MRI, arrival by ambulance, and presentation to a Primary(More)
This paper presents a robust method for recognizing human faces with varying illumination as well as partial occlusion. In the proposed approach, a dual-tree complex wavelet transform (DTCWT) is employed to normalize the illumination variation in the logarithm domain. In order to minimize the variations under different lighting conditions, appropriate low(More)
