The objective of the study was to investigate the antigen specificity and occurrence of individual autoantibodies in mothers of children diagnosed with atrioventricular (AV) block in a nation-wide setting. Patients with AV block detected before 15 years of age were identified using national quality registries as well as a network of pediatric and adult(More)
Forty-one children receiving maintenance treatment for leukemia were vaccinated with inactivated mumps virus, meningococcal polysaccharide groups A and C and polyvalent pneumococcal polysaccharide vaccines. Antibodies against pneumococcal types 3, 18C, 19F and 23F and against meningococcal groups A and C were measured by radioimmunoassay. Mumps antibodies(More)
After a Fontan repair for congenital heart disease, 42 patients underwent graded supine bicycle exercise tests at levels relevant to normal daily activities. Results were compared with those of 28 age-matched normal control subjects. At rest, the cardiac index, stroke index and systolic blood pressure were comparable in both groups, but increases with(More)
Left ventricular dimensions and contractility were determined by echocardiography in 33 patients with tricuspid atresia in 1985 and again in 1988. Eight patients remained palliated throughout the 3-year period; neither the left ventricular end-diastolic diameter (153 +/- 15% of normal vs. 157 +/- 19%, p = NS) nor a load-independent index of contractility(More)
Cardiotoxicity is a potential adverse effect of anthracycline (A) therapy. Radiotherapy (XRT) may also cause a variety of cardiac complications. The purpose of the present study was to evaluate these cardiac side-effects in children and adolescents treated for cancer. We assessed the cardiac status of 91 patients, divided into three groups: Group A (n = 53)(More)
To evaluate the incidence, mortality, late outcome, and cause of central venous thrombosis after pediatric heart operations and other operations performed with cardiopulmonary bypass, we identified patients with postoperative central venous thrombosis during a 10-year period at a single pediatric hospital. There had been 1591 open heart (with bypass) and(More)
Prevention of iron deficiency in low-birth-weight infants requires iron supplementation before neonatal iron stores are exhausted. In order to accurately determine when this depletion occurs, we measured the hemoglobin, mean corpuscular volume, serum iron/iron-binding capacity, and serum ferritin in 117 low-birth-weight infants (1,000 to 2,000 gm) from 0.5(More)
Recent studies have suggested that postoperative bleeding is decreased in pediatric heart operations if fresh whole blood instead of blood component therapy is used for postoperative transfusions. Because this is in contrast to our practice to use whole blood for only the priming of the cardiopulmonary bypass circuit and then to use blood components for(More)
OBJECTIVE Congenital heart block may develop in the fetuses of Ro/SSA-positive and La/SSB-positive mothers. Recurrence rates of only 10-20% despite persisting maternal antibodies indicate that additional factors are critical for the establishment of heart block. The authors investigated the influence of other maternal and fetal factors on heart block(More)
Of 41 pediatric patients currently alive after total body irradiation (TBI) and bone marrow transplantation (BMT), 30 (allogeneic 20, autologous 10) participated in the study. Pre-transplant therapy included high-dose cyclophosphamide (CY) and TBI (n = 12), high-dose CY alone (n = 4), high-dose Ara C and TBI (n = 5), cisplatinum, high-dose melphalan, VP-16(More)
