The development of donor-specific HLA antibodies (DSA) is associated with worse renal allograft survival in adult patients. This study assessed the natural history of de novo DSA, and its impact on renal function in pediatric renal transplant recipients (RTR). HLA antibodies were measured prospectively using single-antigen-bead assays at 1, 3, 6 and 12(More)
Current mainstay treatment for pulmonary embolism (PE) includes oral anticoagulation, thrombolytic therapy, catheter embolectomy and acute surgical embolectomy. Surgical embolectomy is reserved for hemodynamically unstable patients (cardiogenic shock, cardiac arrest) and contraindication to thrombolytic therapy. We report a case of saddle PE in a young(More)
Isolated supravalvular aortic stenosis in adults is a rare form of left ventricular outflow tract obstruction. We describe a case in a 41-year-old man in whom the supravalvular aorta had narrowed to approximately the size of the left anterior descending coronary artery. The patient underwent aortic surgery with replacement of the ascending aorta and repair(More)
CONTEXT Microalbuminuria is a known indicator of atherosclerosis and its association with ischemic heart disease (IHD) has been extensively studied in the diabetic population. The significance of urine microalbumin in non-diabetics, however, is yet to be elucidated. AIM To determine whether an independent association exists between microalbuminuria and(More)
Aim: An aortic dissection is an uncommon serious condition, which usually presents with chest pain or upper back pain. Symptoms of aortic dissection may mimic those of other diseases, often leading to delay in diagnosis. Methods: We report an unusual case of aortic dissection with hemopericardium and thrombosed left common iliac artery presenting as acute(More)
A common approach to pattern classification problems is to train a bank of layered perceptrons or other classifiers by clustering the input training data and training each classifier with just the data from a specific cluster. There is no provision in such an approach, however, to assure the component layered perceptron is well suited to learn the training(More)
A 61-year-old man with a personal history of smoking and a family history of coronary artery disease presented with what he described as a squeezing pain in the left side of his chest that woke him from sleep. He also had associated dizziness and diaphoresis. His heart rate was 85 beats per minute, and he was hypotensive (blood pressure, 90/60 mm Hg). An(More)
