To the Editor: Preterm birth is not, as Muglia and Katz (Feb. 11 issue)1 conclude, an “enigma” justifying passionate enthusiasm for “further knowledge of the biology” and investment in “talented investigators from diverse disciplines [who] need to work together, sharing databases, biologic samples, and intellectual perspectives.”1 We need first of all to(More)
We report a case ofPseudomonas aeruginosa liver abscesses following endoscopic retrograde cholangiopancreatography (ERCP) in a patient without evidence of biliary tract disease and of any known cause of hepatic infection. Computer tomography (CT) scan was the best method of diagnosis, allowing, through guided percutaneous puncture of the abscesses,(More)
The effect of metronidazole on liver function tests was studied in patients given total parenteral nutrition (TPN) for an acute attack of Crohn's disease. In those receiving TPN and metronidazole, serum activities of alkaline phosphatase and gamma-glutamyl-transferase decreased or remained normal after 30 days of TPN. In contrast, serum activities of these(More)
UNLABELLED Colonic pseudolipomatosis is a rare and benign condition. It is not well known by gastroenterologists and its pathogenesis is still unclear. METHODS All cases of colonic pseudolipomatosis seen between February 2002 and June 2004 at the Amiens Universisty Hospital were identified and analyzed. RESULTS During this period, 2099 colonoscopies(More)
Free and conjugated noradrenaline concentrations were measured in portal-venous and arterial plasma from sham-operated rats or rats with portal hypertension. Two types of portal hypertension in rats were evaluated: in portal vein stenosed rats, the liver was normal, whereas cirrhosis developed in bile duct ligated rats. In cirrhotic rats, arterial free(More)
In patients with cirrhosis, the significance of elevated plasma catecholamine concentrations is unclear. Thus we investigated the relationship between plasma catecholamine concentrations and the hemodynamic effect of pindolol (an index of sympathetic vascular tone) in 10 patients with cirrhosis. Systemic and splanchnic hemodynamics and plasma catecholamine(More)
The endoscopic features of the gastric mucosa in patients with cirrhosis have not been systematically investigated. In these patients, we observed an endoscopic aspect, consisting of multiple small erythematous areas, outlined by a subtle yellowish network (resembling a mosaic), mainly located in the proximal part of the stomach. We tested the value of this(More)
Systemic and splanchnic hemodynamics of the chronic bile duct-ligated rat were characterized by radioactive microspheres. Conscious and pentobarbital sodium-anesthetized, bile duct-ligated and sham-operated rats had cardiac output and regional organ blood flows determined. The conscious bile duct-ligated rat compared with the sham-operated showed a(More)
