Abstract: Necrotizing enterocolitis (NEC) is an inflammatory process, characterized by intestinal necrosis of variable extension, leading to perforation, generalized peritonitis and death. The classical pathogenetic theory focuses on mucosal damage related to a stress induced intestinal ischemia leading to mucosal injury and bacterial colonization of the wall. A more recent hypothesis emphasizes the role of immaturity of gastrointestinal and immune system, particularly of the premature, responsible of bowel wall vulnerability and suffering. NEC is the most common gastrointestinal emergency in the newborn, with a higher incidence in the preterm; improvement of neonatal resuscitation techniques enables the survival of premature of very low birth weight (VLBW) with prolongation

  • Gastric Outlet Obstruction in a Patient with Bouveret's
    Nabais et al. BMC Research Notes 2013, 6:195 http://www.biomedcentral.com/1756-0500/6/195 CASE REPORT Open Access Gastric outlet obstruction in a patient with Bouveret’s syndrome: a case report Celso Nabais*, Raquel Salústio, Inês Morujão, Francisco V Sousa, Eusébio Porto, Carlos Cardoso and Caldeira Fradique Abstract Background: Gallstone ileus accounts for 1% to 4% of cases of mechanical bowel obstruction, but may be responsible for up to 25% of cases in older age groups. In non-iatrogenic cases, gallstone migration occurs after formation of a biliary-enteric fistula. In fewer than 10% of patients with gallstone ileus, the impacted gallstones are located in the pylorus or duodenum, resulting in gastric outlet obstruction, known as Bouveret’s syndrome. Case presentation: We report an 86-year-old female who was admitted to hospital with a 10-day history of persistent vomiting and prostration. She was in hypovolemic shock at the time of arrival in the emergency department. Investigations revealed a gallstone in the duodenal bulb and a cholecystoduodenal fistula. She underwent surgical gastrolithotomy. Unfortunately, she died of aspiration pneumonia on the fourth postoperative day. Conclusion: This case shows the importance of considering Bouveret’s syndrome in the differential diagnosis of gastric outlet obstruction, especially in the elderly, even in patients with no previous history of gallbladder disease. Keywords: Bouveret’s syndrome, Gallstone ileus, Gastric outlet obstruction, Cholecystoduodenal fistula Background syndrome in which other comorbidities added to the Gallstone ileus is a rare complication of gallstone diagnostic challenge. disease, causing 1% to 4% of cases of mechanical bowel obstruction.

  • Peritoneal Fluid in the Rabbit: Permeability of the Mesothelium to Proteins, Lipoproteins and Acid Hydrolases F.C
    Lymphology 8 (1975) 1-10 (Q Georg Thieme Verlag, Stuttgart Peritoneal Fluid in the Rabbit: Permeability of the Mesothelium to Proteins, Lipoproteins and Acid Hydrolases F.C. Courtice, D.C.K. Roberts Department of Experimental Pathology, John Curtin School of Medical Research, Australian National University, Canberra Summary The peritoneal fluid in rabbits fed a normal and a cholesterol added diet was analysed for a wide variety of macromolecules of different size, viz albumin, a-, /J- and -y-globulins, high density lipoprotein and lipoproteins of Sf0-12, Sfl2-20 and Sf>20 and three acid hydrolases, N-acetyl--/hi-glucosaminidase, acid phosphatase and /J-glucuronidase. The composition of the lipoproteins and the concentrations of each substance were compar­ ed with corresponding values in plasma, hepatic lymph, thoracic duct lymph and leg lymph. The results indicate that the large lipoproteins of the thoracic duct lymph derived from the intestinal mucosa do not normally enter the peritoneal cavity probably because they do not mix with the subserous tissue fluid, that the macromolecular composition of peritoneal fluid resembles that of leg lymph, that the peritoneal meso­ thelium is freely permeable to these macromolecules and that the main plasma: peritoneal fluid barrier resides in the blood capillary membrane of the various subserous tissues. Introduction The peritoneal cavity usually contains a small amount of free fluid which has a protein concen­ tration of about 2.5 g/100 ml (2, 35). The origin of this fluid is not certain, but it is probably derived from the several adjacent subserous tissue fluid pools. The mechanisms concerned in the passage of proteins through the mesothelial lining of the cavity are, however, not well under­ stood.
