Prospective evaluation of platelet activation and hypercoagulability was performed in 31 patients with Kawasaki syndrome. Most patients had elevated acute-phase reactants when studied during the first 3 weeks of their illness; 17 of 25 (68%) patients had factor VIII activity greater than 150%, 18 of 24 (75%) had fibrinogen greater than 400 mg/dl, and 17 of(More)
The cardiac catheterization data of six infants with bronchopulmonary dysplasia (BPD) were reviewed to examine the responsiveness of their pulmonary vascular beds to changes in oxygen tension. The infants were studied because of slow recovery from their oxygen requirements and clinical evidence of persistent pulmonary hypertension. All were receiving home(More)
Inhaled nitric oxide (iNO) causes selective pulmonary vasodilation by increasing pulmonary vascular levels of cyclic guanosine monophosphate (cGMP). Dipyridamole, a drug with several putative vasodilator mechanisms, is an inhibitor of cGMP-specific phosphodiesterases (PDE5); it therefore has the potential to increase pulmonary vascular cGMP levels, lower(More)
OBJECTIVE To describe a case of spontaneous chylothorax in a child with Noonan syndrome successfully treated with prednisone. DESIGN Case report. SETTING A pediatric cardiology referral center for the Rocky Mountain region. PATIENT An 18-month-old girl with Noonan's syndrome, pulmonary stenosis, and hypertrophic cardiomyopathy who presented with(More)
We report an unselected series of eight patients younger than 6 months of age with Kawasaki disease evaluated between January 1982 and May 1984. The incidence of coronary artery aneurysms (six patients) and the mortality (two patients) were unusually high in this small series. Because of the confusing clinical presentation in three patients, diagnosis was(More)
Hippocampal gamma oscillations have been associated with cognitive functions including navigation and memory encoding/retrieval. Gamma oscillations in area CA1 are thought to depend on the oscillatory drive from CA3 (slow gamma) or the entorhinal cortex (fast gamma). Here we show that the local CA1 network can generate its own fast gamma that can be(More)
Mucocutaneous lymph node syndrome (MLNS), or Kawasaki's disease, affects thousands of infants and children each year and is associated with a high incidence of coronary artery aneurysm, which may lead to subsequent myocardial infarction. Successful use of the right subclavian-axillary artery to bypass a thrombosed aneurysm of the left anterior descending(More)
Little data are available on the hemodynamic effects of premedications and anesthetic agents on infants and children. Ketamine is the most frequently used anesthetic agent for cardiac catheterization procedures in pediatric patients with congenital heart disease. Previous reports both suggest and deny ketamine's pulmonary vasoreactive effects. Since the(More)
Between October 1984 and January 1985, the largest outbreak of Kawasaki syndrome reported to date in the continental United States (62 cases) occurred in the Front Range of the Rocky Mountains, extending from Colorado Springs, Colorado, to Cheyenne, Wyoming. Fifty-two (84%) of these Kawasaki syndrome patients lived in the Denver metropolitan area. A(More)
