OBJECTIVE Alerted by the number of patients with transient global amnesia (TGA) in whom Valsalvalike activities immediately preceded the onset of TGA, we have investigated the frequency of patent foramen ovale (PFO) as the prerequisite for paradoxical embolism. DESIGN Case series with comparison to a control group. SETTING Hospitalized and ambulatory(More)
Knowledge of morphofunctional effects on the fetal brain induced by exogenous glucocorticoids is limited. Recently, we reported alterations of both the neuronal cytoskeleton and electrocortical function in the ovine fetal brain after antenatal betamethasone treatment in doses used in perinatal medicine. In the present study we examined whether these changes(More)
BACKGROUND AND PURPOSE Predictors of clinical outcome in aneurysmal subarachnoid hemorrhage (SAH) vary in reliability. Measurement of cerebral venous hemodynamics by transcranial color-coded duplexsonography (TCCS) has become of increasing interest lately, and correlation with intracranial pressure (ICP) seems to be high. The aim of the presented study was(More)
Fifty patients with multiple sclerosis were treated either by corticosteroids given systemically or by intrathecal injection of a steroid crystal suspension. Before and 3 weeks after the beginning of the treatment we examined the patients according to the Expanded Disability Status Scale (EDSS). Four patients had to be excluded from evaluation. In 23(More)
BACKGROUND Clinical studies using ultrasound at diagnostic frequencies in transcranial Doppler devices provided encouraging results in enhancing thrombolysis with tissue plasminogen activator (tPA) in acute stroke. Low-frequency ultrasound does not require complex positioning procedures, penetrates through the skull better, and has been demonstrated to(More)
INTRODUCTION Hashimoto encephalopathy is a very rare autoimmune disease of unknown etiology. The spectrum of clinical manifestations is wide, and there is no characteristic presentation. Because of the good response to corticosteroid treatment, it is important to confirm the diagnosis as fast as possible. CASE REPORT We report an 18-year-old man stroke(More)
OBJECTIVE Superficial siderosis of the central nervous system (CNS) is a rare chronic progressive disorder caused by chronic subarachnoid hemorrhage. We present four patients with superficial siderosis of the CNS to describe the characteristic symptoms, and to discuss the pathogenetic heterogeneity and possible new therapeutic approaches. RESULTS The(More)
Betamethasone has been used extensively to accelerate fetal lung maturation, yet little is known of its effects on neuronal morphogenesis in the developing fetus. Microtubule-associated proteins (MAPs) are a diverse family of cytoskeletal proteins that are important for brain development and the maintenance of neuroarchitecture. Vehicle (n = 7) or(More)
BACKGROUND AND PURPOSE A number of controlled trials have evaluated the benefit of intravenous thrombolysis in acute stroke with inconsistent results. None of these studies assessed the initial vascular status or provided information regarding the recanalization rate after therapy. Further trials need to clarify whether certain subgroups might possibly(More)
OBJECTIVES To evaluate in a prospective multicentre setting the feasibility of transcranial colour coded duplex sonography (TCCS) for examination of the middle cerebral artery (MCA) in patients with acute hemispheric stroke, and to assess the validity of sonographic findings in a subgroup of patients who also had a correlative angiographic examination.
