UNLABELLED Local anesthetics decrease postoperative pain when placed at the surgical site. Patients benefit from laparoscopic extraperitoneal hernia repair because this allows earlier mobilization than the more classical open surgical approach. The purpose of this study was to determine the pain-sparing efficacy of local anesthetics placed in the(More)
This study was designed to determine the effect of coronary reperfusion on (1) myocardial infarct size and (2) the accuracy of previously reported methods for estimation of infarct size serum creatine phosphokinase (CPK) values. Thirty mongrel dogs, chronically prepared, were studied in the awake state, and were divided into four groups according to the(More)
The authors report an initially successful left gastric artery embolization performed because of massive upper gastrointestinal bleeding; the procedure was complicated by focal gastric and hepatic infarctions. These complications occurred in the absence of underlying factors known to predispose to ischemia. Low-grade gastric bleeding persisting after(More)
Sixty-one randomly selected patients who underwent lumbar fusion surgeries for discogenic low back pain between 1987 and 1994 were retrospectively studied. All patients had failed to respond to preoperative conservative treatments. Forty-two patients received adjunctive therapy with pulsed electromagnetic field (PEMF) stimulation, and 19 patients received(More)
Right and left ventricular volume variables were obtained in 43 tetralogy patients undergoing diagnostic cardiac catheterization. The patient population consisted of 25 preoperative patients (group 1) and 18 patients who had undergone aortic-to-pulmonary shunt procedure (group 2). Volumes were calculated from biplane cineangiocardiograms using Simpson's(More)
A primary squamous-cell carcinoma of the breast was evaluated by fine needle aspiration cytology in a 41-year-old female. The subsequent mastectomy specimen contained a well-differentiated keratinizing squamous-cell carcinoma. On electron microscopic evaluation, the tumor cells contained well-formed desmosomes and prominent bundles of tonofilaments, typical(More)
The feasibility of determining left atrial volumes (LAV) from LA echo dimensions was assessed in 36 children (group I) with normal cineangiographically determined LAV and 16 children (group II) with LAV overload. Conventional LA echo dimensions, obtained within 24 hours of cardiac catheterization, were compared to the angiographic LA anterior-posterior(More)
Hemodynamic and ventricular volume parameters were evaluated in 21 patients (24 studies) with total anomalous pulmonary venous return (TAPVR), 11 patients with secundum atrial septal defect (ASD), and eight patients who had complete correction of TAPVR or ASD. Right and left ventricular (RV and LV) volume parameters were calculated according to Simpson's(More)
Perforation of the gallbladder from blunt abdominal trauma is relatively rare, and is usually diagnosed at laparotomy for associated visceral injury. Isolated injury of the gallbladder may be unrecognized leading to delayed diagnosis and its associated increased morbidity. Computerized tomography, sonography, and HIDA Tc99m may be used in the early(More)
The effect of pressure or volume overload on the geometry of the left ventricle (LV) was determined in order to examine the feasibility and accuracy of LV volume determinations from one minor axis or two dimensions (one minor axis and the longest length). The longest length (LL) and minor axis (MA) in both the anteroposterior (AP) view and lateral (LAT)(More)
