Background and Purpose The aims of this prospective and multicenter study were to determine the frequency of anticardiolipin and antinuclear antibodies in an unselected ischemic and hemorrhagic stroke population and to evaluate the clinical significance of these autoantibodies. Methods Over a 1-year period, we collected plasma from 481 consecutive patients(More)
The patient, a 55 year-old man, developed an episode of transient global amnesia. He was a smoker and had hypercholesterolemia. He was found to have a positive rapid plasma reagin test and high levels of anticardiolipin antibodies. Other investigations were negative. The presence in this patient of antiphospholipid antibodies suggests a vascular mechanism(More)
OBJECTIVE To perform a 1-stage meta-analysis of genome-wide association studies (GWAS) of multiple sclerosis (MS) susceptibility and to explore functional consequences of new susceptibility loci. METHODS We synthesized 7 MS GWAS. Each data set was imputed using HapMap phase II, and a per single nucleotide polymorphism (SNP) meta-analysis was performed(More)
Pituitary apoplexy (PA) is currently considered as one of the causes of empty sella (ES). However, in most reported cases the diagnosis of PA was based on anamnesis. A prospective study of three patients diagnosed during the PA episode was carried out. Periodical evaluations of hormone concentrations and cerebral computed tomography images were carried out.(More)

We carried out a prospective study of the prevalence and characteristics of anticardiolipin antibodies (aCL) and migraine on 103 consecutive patients with systemic lupus erythematosus (SLE) derived from three European referral university centers. We also included a control group of 58 patients with migraine not associated with SLE. We interviewed all(More)
