BACKGROUND Neuropsychiatric systemic lupus erythematosus (NPSLE) is associated with increased morbidity and mortality. METHODS We used Diffusion Tensor Imaging (DTI) to assess white matter abnormalities in seventeen NPSLE patients, sixteen SLE patients without NPSLE, and twenty age- and gender-matched controls. RESULTS NPSLE patients differed(More)
Within systemic lupus erythematosus (SLE) patients can be divided into groups with and without central nervous system involvement, the latter being subcategorized as neuropsychiatric systemic lupus erythematosus (NPSLE). While a number of research groups have investigated NPSLE, there remains a lack of consistent application of this diagnostic criteria(More)
To compare the diagnostic value of transesophageal and transthoracic echocardiography in infective endocarditis, paired transesophageal and transthoracic echocardiograms were obtained prospectively for 66 episodes of suspected endocarditis in 62 patients. Echocardiographic results were compared with the presence or absence of endocarditis determined by(More)
BACKGROUND Valvular heart disease is the most important cardiac manifestation of systemic lupus erythematosus. We performed a study to determine the relation of valvular disease to other clinical features of lupus, whether or not the valve disease progresses, and the associated morbidity and mortality. METHODS We performed transesophageal echocardiography(More)
Patients diagnosed with Systemic Lupus Erythematosus have similar levels of neuropsychological dysfunction (i.e., 20-50%) as those with Neuropsychiatric Systemic Lupus Erythematosus (NPSLE). We hypothesized a gradient between cognition and white matter integrity, such that strongest brain-behavior relationships would emerge in NPSLE, intermediate in(More)
OBJECTIVE Libman-Sacks endocarditis in patients with systemic lupus erythematosus (SLE) is complicated with thromboembolism, severe valve regurgitation, need for high-risk valve surgery, or death. Transesophageal echocardiography (TEE) is highly accurate for detection of valvular heart disease, but there are no prospective randomized controlled series(More)
We demonstrate an automated, multi-level method to segment white matter brain lesions and apply it to lupus. The method makes use of local morphometric features based on multiple MR sequences, including T1-weighted, T2-weighted, and fluid attenuated inversion recovery. After preprocessing, including co-registration, brain extraction, bias correction, and(More)
Pericarditis was the primary manifestation of aortic dissection in these 2 young men. Both patients had no phenotypic characteristics of Marfan or Ehlers-Danlos syndrome. These patients had pleuritic chest pain and characteristic electrocardiographic changes consistent with pericarditis. However, timely performed transthoracic echocardiograms revealed(More)
