Review of the literature and the results of the hospital survey substantiate the widely held belief that fine-needle aspiration biopsy is a very safe procedure. However, serious and even fatal complications, although rare, can and do occur and it is important to be aware of the possibility and to take all the appropriate precautions in order to reduce their(More)
The homeostatic response of complex eukaryotes to the challenge of environmental stress includes the induction of several programs of gene expression; among them are those for the acute phase genes and those for the heat shock genes. In some systems, the heat shock response, which is often elicited by more severe stimuli, preempts the acute phase response,(More)
Over the past several decades screening for disease in large asymptomatic populations has increased, culminating most recently with a federal mandate for early, periodic screening, diagnosis and treatment of all children from low-income families. The present study of five consecutive examinations in over 12,000 schoolchildren shows the cumulative occurrence(More)
The diagnosis of peritoneal mesothelioma was made prospectively and noninvasively in four patients with the use of sonography, computed tomography, and sonographically guided fine-needle aspiration biopsy. The imaging methods revealed information similar to the operative findings, with clear superiority of computed tomography over sonography. These(More)
A mechanical infusion pump was used to introduce 99mTc-sulfur colloid at a rate of 1 ml/minute into the hepatic arteries of six patients. The radiotracer distribution patterns were compared to those obtained with "bolus" radionuclide angiography and those seen with standard contrast angiography. In all cases, the slow flow rate radionuclide studies(More)
Dilatation of unobstructed extrahepatic bile ducts was observed in patients with conditions associated with intestinal hypomotility. For further investigation of this association, a prospective study was undertaken in which the common hepatic duct was measured in 15 patients before and 1 day after laparotomy, when all patients had postoperative paralytic(More)
Proinflammatory cytokines upregulate endothelial adhesion molecule expression, thereby initiating the microvascular inflammatory response. We re-evaluated the reported role of reactive oxygen metabolites (ROMs) in signalling upregulation of intercellular adhesion molecule 1 (ICAM-1) on endothelial cells by tumour necrosis factor alpha (TNF-alpha) in vitro.(More)
