Two-dimensional echocardiography is increasingly used to measure aortic root dimensions, which provide prognostic information in aortic regurgitation and the Marfan syndrome. Aortic root dilatation is currently detected by nomograms based on M-mode echocardiographic data. Aortic root diameters measured by 2-dimensional echocardiography at the anulus,(More)
Postoperative fever and pericardial-pleural reaction, designated postpericardiotomy syndrome (PPS), is a common complication of cardiac surgery involving entry into the pericardium. To determine whether the etiology of PPS is viral or immunologic, we undertook a prospective, triple-blind study of consecutive long-term survivors of intrapericardial surgery(More)
To evaluate the pulsed Doppler cardiac output method as a noninvasive means for determining cardiac output in critically ill children, we performed paired pulsed Doppler and thermodilution cardiac output determinations in 17 critically ill children. Commercially available equipment, specifically designed for this purpose, was employed. Forty paired(More)
Systematic, prospective data regarding phenotypic features, including echocardiographic findings, in pediatric patients with the Marfan syndrome are lacking. In addition, limited and conflicting information exists regarding the impact of pharmacologic therapy on aortic growth rate in children. Fifty-three children and adolescents with the Marfan syndrome(More)
Coagulase-negative staphylococci are important causes of bacteremia and focal infections in infants hospitalized in neonatal intensive care units. The medical records and echocardiograms of 58 newborns with persistent Staphylococcus epidermidis bacteremia who were hospitalized in the neonatal intensive care unit at The New York Hospital during the past 5(More)
Epidemiologic and clinical features of Kawasaki disease in 106 patients seen between 1980 and 1986 at The New York Hospital in midtown Manhattan were compared with those in large series from the United States, Canada, and Japan. Dissimilarities in our Kawasaki disease experience included ethnic heterogeneity of our patients (50% white, 18% black, 16%(More)
Pulmonary function tests, including measurements of arterial blood gas levels, total pulmonary compliance, and arterial-alveolar oxygen ratios, were performed in 38 ventilator-dependent preterm infants with respiratory distress syndrome who weighed less than 1500 g at birth. Twenty-seven had a physiologically significant patent ductus arteriosus (PDA).(More)
Since January 1980, 110 children having 113 attacks of Kawasaki syndrome were studied. Age at onset was 7 weeks to 12 years (mean 3 6/12 years, median 2 9/12 years); 77% were younger than 5 years of age; the male to female ratio was 1.8; racial distribution was 52% white, 19% black, 14% Hispanic, and 16% Asian. Protocol of management consisted of high-dose(More)
