OBJECTIVE To assess the true prevalence of congenital complete heart block (CCHB) in infants of anti-Ro/SSA-positive women known to have connective tissue disease (CTD) and, secondarily, to evaluate the prevalence of other electrocardiographic abnormalities in these newborns at birth. METHODS A prospective study was conducted in 4 referral hospitals. One(More)
PROBLEM To determine which autoantibodies are associated with reproductive failure. METHOD OF STUDY Sera from 269 patients with autoimmune disease and/or reproductive failure were analyzed for anti-phospholipid (aPL), anti-annexin-V, anti-lactoferrin, anti-thyroglobulin, anti-thyroid peroxidase, anti-prothrombin, anti-nuclear, and anti-saccharomycetes(More)
We have prospectively followed 25 pregnancies in 21 patients: 20 were affected by systemic lupus erythematosus (SLE) and 1 by subacute cutaneous lupus erythematosus (SCLE). A flexible treatment schedule was applied to the follow-up of all the pregnancies, and included low dose aspirin, steroids at medium-low dosage and, if needed, azathioprine (AZA) after(More)
A statistical analysis and computational algorithm for comparing pairs of tool marks via profilometry data is described. Empirical validation of the method is established through experiments based on tool marks made at selected fixed angles from 50 sequentially manufactured screwdriver tips. Results obtained from three different comparison scenarios are(More)
Estimating the noise parameter in magnitude magnetic resonance (MR) images is important in a wide range of applications. We propose an automatic noise estimation method that does not rely on a substantial proportion of voxels being from the background. Specifically, we model the magnitude of the observed signal as a mixture of Rice distributions with common(More)
Rheumatic diseases in women of childbearing years may necessitate drug treatment during a pregnancy, to control maternal disease activity and to ensure a successful pregnancy outcome. This survey is based on a consensus workshop of international experts discussing effects of anti-inflammatory, immunosuppressive and biological drugs during pregnancy and(More)
Beta-2-GPI is a 50 kDa glycoprotein which is known to be a serum co-factor, with a role in determining the binding of pathogenic anticardiolipin antibodies to phospholipids. Immunization of naive mice with beta-2-GPI resulted in elevated levels of antibodies directed against negatively charged phospholipids (cardiolipin, phosphotidylserine,(More)
OBJECTIVE To evaluate the prevalence in normal pregnancies of anti-32 glycoprotein I (anti-beta2GPI) antibodies, and their association with obstetrical complications. STUDY DESIGN Prospective study of anti-beta2GPI and anticardiolipin (CL) antibodies in 510 healthy pregnant women at 15-18 weeks. According to the results, women were categorized into three(More)
OBJECTIVE The purpose of this study was to compare the effectiveness of low-molecular-weight heparin with regular heparin in the prevention of fetal resorption in mice with the antiphospholipid syndrome. STUDY DESIGN Antiphospholipid syndrome was passively induced in ICR mice by injecting them with anticardiolipin antibodies on the first day of pregnancy.(More)
This study was undertaken to determine if there is an association between increased titers of five different antiphospholipid antibodies (aPLA) in young patients' sera and the occurrence of acute myocardial infarction (AMI). Antibodies to anticardiolipin (aCL), anti-phosphatidylserine (aPS), antiphosphatidylinositol (aPI), anti-phosphatidylcholine (aPC),(More)
