OBJECT The aim of this study was to evaluate whether the level of a spinal lesion is associated with variations in anomalous brain development and neurobehavioral outcomes in children suffering from the meningomyelocele form of spina bifida and hydrocephalus (SBM-H). METHODS Two hundred sixty-eight children with SBM-H were divided into upper (T-12 and(More)
Neural tube defects (NTDs) constitute a major group of congenital malformations with an overall incidence of approximately 1-2 in 1,000 live births in the United States. Hispanic Americans have a 2.5 times higher risk than the Caucasian population. Spina bifida meningomyelocele (SBMM) is a major clinical presentation of NTDs resulting from lack of closure(More)
We studied mononuclear cell subsets in 17 patients with primary Sjögren's syndrome (PSS) and in 11 normal controls by flow cytometry. We found a decreased percentage of CD4+ cells (p = 0.027) and a higher percentage of CD8+ cells in patients as compared to controls. In both, CD4+ cells and CD8+ cells, CD25 antigen was overexpressed (p = 0.005 and p = 0.025,(More)
With a cross sectional study of 465 consecutive systemic lupus erythematosus (SLE) patients tested for 13 autoantibodies (Aab) and two idiotypes we determined the prevalence of Aab according to disease activity, both general and at particular organ systems. Seventy seven percent of SLE sera had at least one Aab and 56% had it at high titres. Pathogenic(More)
Primary Sjögren's syndrome (PSS) is an autoimmune inflammatory disorder characterized by lymphocytic infiltration of exocrine glands, B cell hyperactivity and autoantibody production. The aim of this study was to determine the presence of IL-10 and IL-13 in this disease. We studied the IL-10 and IL-13 gene expression in vivo by peripheral blood mononuclear(More)
The pattern of inheritance of autoantibodies in eight families chosen from a pool of 110 families of patients with systemic lupus erythematosus (SLE) is described. In all the eight families at least two members were already affected by SLE. In total, 19 patients and 43 first degree relatives were examined. The inheritance of a large set of antinuclear(More)
Patients with primary antiphospholipid syndrome (PAPS) have few or no autoantibodies, other than the antiphospholipid antibodies (aPL) that could be natural autoantibodies encoded by germline genes. Some of the autoantibodies marked by the human anti-DNA common idiotype 16/6 have been found to be encoded by unmutated germline genes. Hence, we tested the(More)
