We examined a case of malignant degeneration that occurred as a long-term complication of a choledochal cyst. Analysis of the literature shows the incidence of carcinoma varies with age at the initial appearance of symptoms. The child with a choledochal cyst that appears before 10 years of age carries a minimum risk (0.7%) of subsequent malignant(More)
Our study addressed reproductive character displacement between two subspecies of the house mouse, Mus musculus musculus and Mus musculus domesticus that hybridize in Europe along a zone where selection against hybridization is known to occur. Based on a multi-population approach, we investigated spatial patterns of divergence of mate preference in the two(More)
Single, small hepatocarcinomas (HCC) are still an indication for partial liver resection in patients ineligible for transplantation. Anatomical resections are recommended for oncological reasons. The mini-invasive approach of laparoscopy should minimize hepatic and parietal injury, thereby decreasing the risk of liver failure and ascites. However, the(More)
We study the form of the clines in a female mating preference and male display trait using simulations of a hybrid zone. Allopatric populations of two species are connected by demes in a stepping stone arrangement. Results show that reproductive character displacement (a pattern of increased prezygotic isolation in sympatry compared with allopatry) may or(More)
This study was undertaken to determine the results of resection of hepatocellular carcinoma in cirrhotic patients in Europe, using the same criteria as in the Orient for detection, surgical management, and pathology of the tumors. Seventy-two patients had a liver resection. One- and 3-yr survival rates were 68% and 51%, respectively. Survival rate was(More)
In patients presenting with acute diverticulitis (AD) and signs of acute peritonitis, the presence of extradigestive air (EDA) on a computer tomography (CT) scan is often considered to indicate the need for emergency surgery. Although the traditional management of “perforated” AD is open sigmoidectomy, more recently, laparoscopic drainage/lavage (usually(More)
Metabolic and hormonal responses to the administration of a gastric load of glucose (2.4 mg/g body wt) were evaluated after a fast of 6-7 h in unrestrained rats bearing a portal vein catheter. For the purpose of this study, we have designed a new technique for a direct catheterization of the portal vein that allows serial blood sampling in unrestrained(More)
Evidence is growing in support of the role of stem cells as an attractive alternative in treatment of liver diseases. Recently, we have demonstrated the feasibility and safety of infusing CD34(+) adult stem cells; this was performed on five patients with chronic liver disease. Here, we present the results of long-term follow-up of these patients. Between 1(More)
This article presents further clinical material from the Paris Psychosomatic School (Aisenstein, 2006). The Freudian foundations of psychosomatics are detailed and post-Freudian developments focusing on the contribution of the Paris Psychosomatic School are outlined, in particular, the somatizing process as a result of regression and the somatizing process(More)
Nine patients with Budd-Chiari syndrome (BCS) were treated by a portal systemic shunt. One had thrombosis of the superior mesenteric vein (SMV) and another had complete obstruction of the retrohepatic inferior vena cava (IVC). All other patients had a marked stenosis of the retrohepatic IVC with caval pressure ranging from 12 to 24 mmHg (mean: 17 mmHg).(More)
