Sixty-four patients were evaluated prospectively for a reflex sympathetic dystrophy syndrome (RSDS), using quantitative clinical measurements, high-resolution roentgenography and scintigraphy. Five separate groups were identified by their clinical features, allowing us to distinguish patients with definite or incomplete forms of the RSDS as well as 16(More)
Sixty-four consecutive patients were studied for possible reflex sympathetic dystrophy syndrome (RSDS). They were divided into five groups, based upon specific clinical criteria, and the radiographic and scintigraphic findings in each group were examined. Osteoporosis was the most common radiographic abnormality, present in 69% of subjects with definite,(More)
OBJECTIVE Intimal hyperplasia is considered to be a healing response and is a major cause of vessel narrowing after injury, where migration of vascular progenitor cells contributes to pathological events, including transplant arteriosclerosis. APPROACH AND RESULTS In this study, we used a rat aortic-allograft model to identify the predominant cell types(More)
In order to compare the effectiveness of thaHium-201 (20111) myocardial perfusion scintigraphy and the exercise electrocardiogram for identifying patients with multivessel coronary artery disease, these noninvasive tests and coronary arteriography were performed in 89 patients with prior inferior wall myocardial infarction. Eighty patients performed an(More)
BACKGROUND Growing evidence implicates the involvement of extracellular nucleotides in the regulation of platelet, leukocyte, endothelial cell (EC) and vascular smooth muscle cell (VSMC) phenotype and function. Within the quiescent vasculature, extracellular nucleotides are rapidly hydrolyzed by CD39, the dominant endothelial nucleoside triphosphate(More)
OBJECTIVES Reactivation of Epstein-Barr virus (EBV) infection in renal transplant recipients may cause significant morbidity and mortality. To evaluate factors associated with activation of EBV replication we followed prospectively a group of 65 recipients of cadaveric kidney for 12 months. METHODS Sera were collected periodically from these patients and(More)
