Eight children, who needed walkers to ambulate and who were able to use either anterior or posterior walkers, were selected for a comparative study of both types of walker. Data for gait analysis, using high-speed cinematography, were collected to determine stride length, time in double support and velocity. Trunk, hip and knee angles were also measured(More)
A recent accumulation of surgical and radiological literature has helped spine surgeons to better understand the anatomy and establish surgical trajectories to the anterior L4-L5 disc space. However, the preoperative display of anatomic data in individual subjects in the three-dimensional (3-D) mode has rarely been attempted. The objective of this study was(More)
BACKGROUND The study analyzed the effect of atrial septal defect (ASD) device closure on regional wall motion in the right (RV) and left ventricles (LV) using color tissue Doppler imaging (TDI). Atrial septal defect closure results in acute volume unloading of the RV. For unknown reasons, some patients develop acute left-sided heart failure(More)
This study was conducted to determine the utility of metal detection in coin localization by inexperienced operators, and determine the rate of spontaneous passage of asymptomatic esophageal coins. All children who presented to the emergency department of an urban children's hospital with a suspected coin ingestion were eligible. Coin location was predicted(More)
BACKGROUND In adults, an acute decrease of regional myocardial velocities is a sensitive marker of rejection. In children, velocities are more variable. A new marker, myocardial acceleration during isovolumic contraction (IVA), appears to be less age-dependent than myocardial velocities. This study therefore compared tissue Doppler (TDI)-derived velocities(More)
BACKGROUND Tissue Doppler imaging (TDI), a non-invasive echocardiography technique, permits quantitative analysis of the regional distribution pattern of myocardial velocities. During normal childhood development, regional function changes markedly, including an increasing predominance of longitudinal velocities. This study analyzed the impact of heart(More)
