OBJECTIVE To determine the prevalence of alpha-synuclein (AS) aggregates in abdominopelvic autonomic plexuses in the general population and to evaluate the relationship between this finding and the subsequent development of neurologic dysfunction. METHODS First, surgical specimens from 100 patients (ages 44 to 84) undergoing a wide resection of an(More)
BACKGROUND Carotid body (CB) glomus cells are highly dopaminergic and express the glial cell line derived neurotrophic factor. The intrastriatal grafting of CB cell aggregates exerts neurotrophic actions on nigrostriatal neurons in animal models of Parkinson disease (PD). OBJECTIVE We conducted a phase I-II clinical study to assess the feasibility, long(More)
OBJECTIVE To describe the frequency of antibodies against neurofascin in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and the associated clinical features. METHODS Immunocytochemistry was used to identify antibodies to neurofascin 155 (NF155) and 186. Serum reactivity with paranodes and brain tissue was tested with immunohistochemistry(More)
OBJECTIVE To describe the response to rituximab in patients with treatment-resistant chronic inflammatory demyelinating polyneuropathy (CIDP) with antibodies against paranodal proteins and correlate the response with autoantibody titers. METHODS Patients with CIDP and IgG4 anti-contactin-1 (CNTN1) or anti-neurofascin-155 (NF155) antibodies who were(More)
BACKGROUND Bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) is favoured over bilateral globus pallidus internus (Gpi) DBS for symptomatic treatment of advanced Parkinson's disease (PD) due to the possibility of reducing medication, despite lack of definitive comparative evidence. OBJECTIVE To analyse outcomes after one year of bilateral(More)
INTRODUCTION Lewy body disorders such as Parkinson's disease (PD) and Lewy body dementia (LBD) are associated with cardiac sympathetic denervation, which can be visualized on 123I-MIBG scintigraphy. Our objectives were to study the diagnostic value of this technique in Lewy body disorders and its relationship with PD clinical variables. PATIENTS AND(More)
INTRODUCTION Fibrinolysis in stroke should be carried out as soon as possible, but delays occur for various reasons. In the first 17 ischemic infarcts treated in our center we confirmed a tendency to exhaust the therapeutic window. We look now at whether warnings against this tendency, without other logistical or organizational modifications, have had an(More)
INTRODUCTION The effectiveness of stimulating the subthalamic nucleus (DBS-STN) in advanced Parkinson's disease (PD) largely depends on the correct placement of the electrodes. Since the sensory-motor region of the STN lies beside the internal capsule (IC), we believe that the motor effectiveness of DBS-STN could be related to the stimulation threshold in(More)
