Two hundred forty previously healthy military personnel with nonstreptococcal upper respiratory infections were prospectively studied to define the incidence and clinicopathologic characteristics of possible virus-associated glomerulonephritis. Nine patients without preceding streptococcal infection had erythrocyte casts on urinalysis and glomerulonephritis(More)
Analysis of a tapering, pulsatile flow field predicts that substantial subvalvular pressure gradients exist in patients with valvular aortic stenosis (AS) without invoking a second anatomic site of obstruction. Using a catheter with two laterally mounted micromanometers, we examined the left ventricle in 11 patients with AS, mean age 64 +/- 11 years (+/-(More)
Changes in the physiologic state of the patient may affect indices of valvular aortic stenosis. We determined the effects of supine exercise on the Gorlin valve area, Cannon valve area, aortic valve resistance, and a modified stroke work loss index in 80 patients with aortic stenosis. Exercise caused a significant increase in the Gorlin and Cannon valve(More)
BACKGROUND Patterns for nonoperative management of pediatric blunt splenic injuries (BSIs) vary significantly within and between institutions. The indications for repeated imaging, duration of activity restrictions, as well as the impact of volume and type of trauma center (pediatric vs. adult) on outcomes remain unclear. METHODS A retrospective review of(More)
