BACKGROUND The efficacy of laparoscopy simulators remains controversial. METHODS This was a comparative prospective study that evaluated the impact of simulator training on technical competence during a real surgical procedure. Residents were divided into 3 groups: the Mcgill Inanimate System for Training and Evaluation of Laparoscopic Skills (MISTELS)(More)
Hemorrhage after pancreaticoduodenectomy is a life-threatening complication, which occurs in 4% to 16% of cases, even in experienced centers. Many diagnostic and therapeutic options exist but no one has yet established management guidelines. This study aimed to determine the role of conservative management in delayed hemorrhage. From January 2005 to August(More)
BACKGROUND Literature series that include visceral artery pseudoaneurysms rarely separate them from true aneurysms, although they address different issues. Guidelines for optimal management of these lesions are lacking. We report our experience of stent graft treatment of these lesions with midterm results. METHODS We retrospectively reviewed all patients(More)
Solitary fibrous tumors (SFTs) are mesenchymal neoplasms of fibroblastic origin, most commonly found in the pleura. Numerous extrathoracic locations have been reported during the last 2 decades. Herein, we report the first case of an SFT in the round ligament of the liver. A 46-year-old Caucasian man presented with a 12-month history of abdominal pain. An(More)
BACKGROUND Segmental reversal of the small bowel (SRSB) is proposed in patients with short-bowel syndrome (SBS) as a rehabilitative therapy, but its effects on absorption have not been studied. OBJECTIVE We aimed to determine intestinal macronutrient absorption and home parenteral nutrition (HPN) dependence in SBS patients with intestinal failure. (More)
Microdeletion of chromosome 22q11.2, the most common human deletion syndrome encompasses a wide spectrum of abnormalities. Many clinical or ultrasonographic findings may support deletion studies, either in utero or in the post-natal period. The objective of our study was to evaluate the circumstances of 22q11.2 deletion diagnosis in a single centre of(More)
EX645 is a derivative of Salmonella typhi Ty21a which carries a plasmid specifying production of Vibrio cholerae O antigen. When cultured with exogenous galactose to overcome the galE defect of the vector, EX645 also synthesizes S. typhi O antigen, and this can result in the masking of the shorter V. cholerae O antigen on the bacterial surface. To determine(More)
The short-term kinetics and the effects of different dose regimens and formulations on the humoral immune response induced in human subjects by the live attenuated typhoid vaccine Salmonella typhi Ty21a were examined. Antibody responses in jejunal fluid and serum and by specific antibody production in vitro by peripheral blood lymphocytes to S. typhi(More)
Salmonella typhimurium G30 was used as a vector to express the ETEC (enterotoxigenic Escherichia coli) fimbrial antigens K88 and K99. Two plasmids encoding K88 or K99 production and having a non-antibiotic selection marker (thyA+) were constructed. These were introduced into a thyA G30 derivative to give the vaccine strains EX841 and EX603, which were shown(More)
