OBJECTIVES The objective of this study was to find the predictors and generate a prediction score of resistance to intravenous immunoglobulin (IVIG) in patients with Kawasaki disease (KD). STUDY DESIGN Patients diagnosed as having KD were sampled when they received initial high-dose IVIG treatment (2 g/kg dose) within 9 days of illness (n = 320). These(More)
Diagnostic guidelines for Kawasaki Disease was revised to meet the present situation in 2002. This issue intends to explain new guidelines and their backgrounds. Major alterations are interpretation of cases with 4 or fewer febrile days shortened by early intravenous immunoglobulin treatment, and the clinical importance of atypical (incomplete, or(More)
We assessed the usefulness of transthoracic Doppler-derived indexes obtained in the proximal pulmonary artery (PA) branch for estimating pulmonary vascular resistance (PVR) in 45 children with congenital heart disease (CHD) and 23 normal control subjects. The acceleration time, inflection time (InT), deceleration index, and peak velocity, which were(More)
OBJECTIVE To compare the long-term efficacy of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for stenotic lesions after Kawasaki disease. STUDY DESIGN Questionnaires were sent to pediatricians in Japan in hospitals with 100 or more beds. A total of 1637 questionnaires were sent, and 1347 (82%) were returned. The(More)
Although the renin angiotensin system (RAS) is a major regulator of vascular homeostasis, the role of the RAS in tumor angiogenesis is little understood. Here we show that host angiotensin II (ATII) type 1 (AT1) receptor plays an important role in angiogenesis and growth of tumor cells engrafted in mice. Subcutaneous B16-F1 melanoma-induced angiogenesis as(More)
BACKGROUND The purpose of this study was to assess the sequential follow-up results of catheter intervention in Kawasaki disease by use of quantitative coronary angiography (QCA) and intravascular ultrasound imaging. METHODS AND RESULTS Catheter intervention was performed on 23 stenotic lesions in 22 patients (aged 2 to 24 years). Percutaneous balloon(More)
