Ultrasonic features of three cases of liver cell adenoma (LCA) and two cases of focal nodular hyperplasia (FNH) are presented. These tumors have similar sonographic appearances presenting either as solid masses or containing sonolucent areas due to hemorrhage or necrosis. Although these ultrasonic features in patients with an area of decreased activity on(More)
1. Baroreflex sensitivity was tested in three normal, three borderline and one hypertensive subject before and during mental arithmetic, the prolongation of pulse interval caused by a provoked rise in blood pressure being used as a measure of baroreflex sensitivity. 2. Baroreflex sensitivity was significantly decreased during mental arithmetic. 3. During(More)
The comparative protective efficacy of culture-derived Babesia bovis and B. bigemina immunogens against challenge exposure of susceptible crossbred cattle to heterologous strains was examined and correlated with the antigenic threshold requirements for induction of protective immunity. Strong protection was observed in animals vaccinated with 10(More)
BACKGROUND AND STUDY AIMS Linear endoscopic ultrasonography (EUS) is currently favored by many endosonographers for the evaluation of pancreatic pathology. However, radial EUS was used in early studies validating EUS for chronic pancreatitis. Radial and linear EUS have never been compared for the diagnosis of chronic pancreatitis. The aim of this study was(More)
OBJECTIVE To demonstrate that the amount of basilar membrane displacement toward the scala tympani and its attachment to the bony wall of the scala tympani (i.e., interscalar septum) in hydropic temporal bones is related to the intraosseous endolymphatic sac volume. STUDY DESIGN A retrospective analysis of temporal bones from individuals with the(More)
BACKGROUND AND STUDY AIMS Balanced propofol sedation (BPS) combines propofol with opiates and benzodiazepines and targets at moderate sedation. Data comparing outcomes of BPS and standard sedation with opiates and benzodiazepines during elective esophagogastroduodenoscopy (EGD) are sparse. The primary end point of this study was to compare, in the recovery(More)
IntelliVent-ASV® is a development of adaptive support ventilation (ASV) that automatically adjusts ventilation and oxygenation parameters. This study assessed the safety and efficacy of IntelliVent-ASV® in sedated intensive care unit (ICU) patients with acute respiratory failure. This prospective randomized crossover comparative study was conducted in a(More)
We present a case of a pseudoaneurysm of the superior gluteal artery following placement of an iliosacral screw in a patient with an unstable pelvic ring fracture. Percutaneous fixation of posterior pelvic ring injuries is becoming a popular method for pelvic stabilization. Several techniques are available t achieve stability and allow early mobilization in(More)
The value of the electrocardiogram in assessing infarct size was studied using serial estimates of the MB isomer of creatine kinase (CK MB) in plasma, serial 35 lead praecordial maps in 28 patients with anterior myocardial infarction, and serial 12 lead electrocardiograms in 17 patients with inferior myocardial infarction. In patients with anterior(More)
