Iodine and/or selenium deficiency alters tissue distribution pattern of other trace elements in rats.

Tissue distribution of Fe, Mn, Cu, and Zn, the essential trace elements associated with oxidant and/or antioxidant processes, was examined in iodine- and/or selenium-deficient rats (ID, SeD, ISeD). Fe and Mn were the most affected minerals in all types of deficiency states. Mn levels decreased significantly in the liver in all deficiency states (approx 20-30%), in the heart in ID and SeD rats (approx 30-35%) and in the testis in ID rats (approx 15%).

[Resection of the retroportal pancreatic lamina during a cephalic pancreaticoduodenectomy: first dissection of the superior mesenteric artery].

We report a modification of the standard resection of the retroportal pancreatic lamina during pancreaticoduodenectomy. The resection begins with the dissection of the origin of the superior mesenteric artery (SMA) above the left renal vein and a step-by-step section of the retroportal pancreatic lamina on the right side of the SMA, then the pancreatic head is retracted to the left and freed from the portal vein, and lastly the neck of the pancreas is transected. This technique allows a total lymph node clearance, secures the dissection of the SMA, and allows safe identification of anatomic variations like a replaced right hepatic artery originating from the SMA.

[Pancreaticojejunostomy in the treatment of chronic pancreatitis].

Introduction: The aim of this retrospective study was to evaluate the immediate and long-term outcome of pancreaticojejunostomy (PJ) in the treatment of chronic pancreatitis. MATERIAL AND METHODS. - From 1980 to 1997, 140 patients with chronic pancreatitis with dilated Wirsung duct were treated by PJ and were studied retrospectively.

Detection of peritoneal adhesions using ultrasound examination for the evaluation of an innovative intraperitoneal mesh.

Background: In this multicenter study, we evaluated the efficiency of a specific ultrasound examination in detecting postoperative bowel adhesions and assessed the adhesion rate associated with the intraperitoneal use of Parietex composite mesh (polyester mesh covered on the visceral side by a hydrophilic resorbable film).

Methods: Eighty patients (36 male, 44 female; average age, 58.2 years [ranges 30-80]) were included in a study carried out at eight centers.

Evaluation of the permeability of pancreaticogastric anastomoses (PGA) with dynamic magnetic resonance pancreatography after secretin stimulation (secretin MRCP).

Background: Because some investigators have reported the systematic occurrence of exocrine pancreatic insufficiency after pancreaticoduodenectomy with pancreaticogastric anastomosis (PGA), we assessed PGA patency after pancreaticoduodenectomy.

Methods: Nineteen patients underwent pancreaticoduodenectomy, and their PGAs were studied prospectively with secretin magnetic resonance cholangiopancreatography (MRCP). After administration of negative bowel contrast agent, single-shot fast spin-echo T2-weighted dynamic MR pancreatograms were obtained before and every minute for 12 min after secretin injection.

Recurrence rates at minimum 5-year follow-up: laparoscopic versus open sigmoid resection for uncomplicated diverticulitis.

The aim of the study was to compare the impact of surgical access to sigmoid resection on recurrence rates in patients with uncomplicated diverticulitis of the sigmoid (UDS) at a minimum follow-up of 5 years. Recurrence after surgery was defined as left lower quadrant pain, fever, and leucocytosis with consistent CT and enema findings on admission and at 6 weeks, respectively. Outcome measures included splenic flexure mobilization, specimen length, inflammation at proximal resection margin, and presence of teniae coli at distal resection margin.

[Extra-spinal cause of recurrent sciatalgia after disk surgery: a case report].

There is a general consensus concerning the clinical and radiological approach to diagnosis and proper management strategy in patients with sciatalgia subsequent to disk herniation. Recurrent herniation is the most probable diagnosis when pain recurs the same territory long after surgery. Despite advances in computed tomographic and magnetic resonance imaging, it may be difficult to identify the real source of the pain in some patients.

Primary anastomosis after intraoperative colonic lavage vs. Hartmann's procedure in generalized peritonitis complicating diverticular disease of the colon.

Background And Aims: For complicated diverticulitis Hartmann's procedure remains the favored option in patients with acute complicated sigmoid disease, but there has been increasing interest in primary resection and anastomosis with intraoperative colonic lavage. This study compared primary resection with intraoperative colonic lavage and Hartmann's procedure.

Patients And Methods: Between January 1994 and November 2001, 60 patients underwent emergency laparotomy for diverticular peritonitis (Hinchey stages III and IV).

Evidence for gene flow via seed dispersal from crop to wild relatives in Beta vulgaris (Chenopodiaceae): consequences for the release of genetically modified crop species with weedy lineages.

Gene flow and introgression from cultivated to wild plant populations have important evolutionary and ecological consequences and require detailed investigations for risk assessments of transgene escape into natural ecosystems. Sugar beets (Beta vulgaris ssp. vulgaris) are of particular concern because: (i) they are cross-compatible with their wild relatives (the sea beet, B.

Comparison of conventional and laparoscopic ileocolic resection for Crohn's disease.

Purpose: The purpose of this study was to compare open with laparoscopic ileocolic resection in selected patients with refractory Crohn's disease confined to terminal ileum and cecum in terms of small-bowel obstruction and recurrence rates at a follow-up of five years.

Methods: Thirty-nine patients who underwent laparoscopic ileocolic resection during a four-year period were compared with 53 patients who had previously undergone open ileocolic resection by the same surgeons at the same institution. Small-bowel obstruction was any clinical evidence of obstruction requiring hospital admission, regardless of recurrent disease or the need for surgery.

Changes in serum retinol, alpha-tocopherol, vitamin C, carotenoids, xinc and selenium after micronutrient supplementation during alcohol rehabilitation.

Objective: To test the effect of a 21-day supplementation with moderate doses of antioxidant nutrients on biochemical indicators of vitamin, carotenoid and trace element levels in alcohol-dependent patients during a program of alcohol rehabilitation.

Design: A randomized double-blind trial was performed comparing two groups receiving daily either a combination of micronutrients (beta-carotene: 6 mg, vitamin C: 120 mg, vitamin E: 30 mg, zinc: 20 mg, selenium: 100 micro g) or a placebo.

Subjects: 106 alcohol-dependent patients 20 to 60 years of age without severe liver disease, hospitalized for a 21-day rehabilitation program.

[Strangulated obturator hernia: a report of 17 cases].

Purpose Of The Study: To assess clinical, therapeutic and diagnostic findings of strangulated obturator hernias.

Patients And Method: Retrospective study of 17 patients (16 women, 1 man; average age: 81.7 years), all treated in the same service, for strangulated obturator hernia.

Ultrasound detection of visceral adhesion after intraperitoneal ventral hernia treatment: a comparative study of protected versus unprotected meshes.

Intraperitoneal (IP) ventral hernia repair has been proposed with the advantages of reducing dissection, operative time, and postoperative pain. The IP position of the mesh is suspected of increasing the risk of visceral adhesion and inducing complications. To overcome these drawbacks, a mesh protected on one side by a hydrophilic resorbable film (Parietex Composite) has been validated.

TCR dynamics in human mature T lymphocytes lacking CD3 gamma.

The contribution of CD3gamma to the surface expression, internalization, and intracellular trafficking of the TCR/CD3 complex (TCR) has not been completely defined. However, CD3gamma is believed to be crucial for constitutive as well as for phorbol ester-induced internalization. We have explored TCR dynamics in resting and stimulated mature T lymphocytes derived from two unrelated human congenital CD3gamma-deficient (gamma(-)) individuals.

Population genetic structure in a human-disturbed environment: a case study in the land snail Helix aspersa (Gastropoda: Pulmonata).

Local patterns of genetic variation were analysed in the land snail Helix aspersa for 32 populations sampled within a patchy agricultural landscape: the polders of the Bay of Mont-Saint-Michel (France). This investigation examined the allele frequencies at four enzymatic markers and five microsatellite loci through the genotyping of 580 individuals. A strongly significant population genetic substructuring (mean F(ST)=0.
