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)
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)
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)
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 Carotid artery stent placement (CAS) may be associated with clinically silent cerebral lesions. We prospectively evaluated the association of the number of solid cerebral microemboli during unprotected CAS with the frequency of silent cerebral lesions as detected by diffusion-weighted MR imaging (DWI). METHODS We performed(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.

BACKGROUND AND PURPOSE Stent-protected carotid angioplasty (SPAC) is an option for treating cervical symptomatic high-grade internal carotid artery (ICA) stenosis. So far, knowledge about hemodynamic changes in the early postinterventional phase is limited. The purpose of this study was to evaluate these changes. METHODS Thirty-four consecutive patients(More)
PURPOSE In chronic internal carotid artery (ICA) occlusion, cerebral hemodynamics are likely to be stable due to collateral flow. The authors evaluated cerebral hemodynamics in ICA occlusion using the sonographic method of cerebral blood flow volume (CBVF) measurement to find differences that might identify patients with large hemispheric stroke in ICA(More)
