Two-dimensional echocardiograms of the mitral valve orifice area were obtained in 50 normal pediatric subjects, 15 patients with congenital mitral stenosis and 7 patients with tricuspid atresia. The mitral area was measured near the tips of the mitral valve leaflets from a diastolic cross-sectional image of the left ventricle. The cardiac images were(More)
Our hypotheses were that the following factors influenced closure of atrial septal defects (ASDs) detected in neonates: estimated gestational age (EGA), the presence of a persistent ductus arteriosus (PDA), severity of pulmonary disease, gender, and the initial size of the ASD. Our population consisted of 82 newborns (38 premature and 44 term) who were(More)
PURPOSE Lymph node status is important in colorectal cancer. Multiple studies indicate a relationship between the number of nodes harvested and survival. This is important in patients with stage II disease where the role of adjuvant therapy is unclear. This study sought to analyze the impact of lymph node harvest on survival in patients with stage II(More)
OBJECTIVE To determine whether the addition of the aortic-root view would detect more congenital cardiac anomalies than a standard four-chamber view alone. METHODS The study included fetuses of 14 weeks' gestation or more who were scanned in our unit during a 28-month period. Outcome information was obtained from postnatal echocardiograms and autopsies.(More)
Doppler echocardiograms of the tricuspid and mitral valves were recorded along with the electrocardiogram and respiration in 22 normal full-term neonates. A computer-interfaced digitizer pad was utilized to measure the following: peak E and A velocities (cm/s); E and A areas (the components of the total velocity-time integral in the early passive period of(More)
BACKGROUND Although fine-needle aspiration (FNA) is an established tool in the biopsy of breast masses, there has been a trend toward using core-needle biopsy (CNB). The aim of this study was to determine whether FNA has comparable predictive value with CNB and whether FNA is more cost effective. METHODS A retrospective review was conducted on 162(More)
OBJECTIVE To determine whether there is a difference between the types of cardiac lesions detected as abnormal prenatally and those that are not detected. METHODS Consecutive fetuses at 14 weeks' gestation or more were scanned in our unit from February 1990 through July 1995 and later were delivered at our hospital. Outcome information was obtained from(More)
Doppler echocardiograms of the mitral valve were recorded along with electrocardiograms and respirations from 20 diabetics and 16 normal subjects, all aged 10 to 15 years. E and A areas (the components of the total velocity-time integral in the early passive period of ventricular filling [E] and the late active period of atrial emptying [A], respectively),(More)
A functioning immune system and the process of antigen presentation in particular encompass events that occur at multiple length and time scales. Despite a wealth of information in the biological literature regarding each of these scales, no single representation synthesizing this information into a model of the overall immune response as it depends on(More)
