Case Report: Multivisceral Transplantation for an Extensive Cystic Lymphangioma of the Mesenteric Root.

Background: We report the case of a 7-year-old girl with intestinal failure owing to a cystic lymphangioma compromising the root of the mesentery, not amenable to resection, leading to intestinal failure. Oncologic treatment was attempted to reduce tumor size with no response; therefore, she was listed for multivisceral transplantation.

Procedure: Resection of the tumor required resection of all abdominal organs with vascular inflow and outflow.

Long-Term Outcomes of Intestinal and Multivisceral Transplantation at a Single Center in Argentina.

Background: Intestinal failure (IF) patients received parenteral nutrition (PN) as the only available therapy until intestinal transplantation (ITx) evolved as an accepted treatment. The aim of this article is to report the long-term outcomes of a series of ITx performed in pediatric and adult patients at a single center 9 years after its creation.

Patients And Methods: This is a retrospective analysis of the ITx performed between May 2006 and January 2015.

β-Cyclodextrin and permeability to water in the bladder of Bufo arenarum.

We measured the effect of β-cyclodextrin (BCD, a cholesterol scavenger) on water flow across the isolated toad bladder exposed to an osmotic gradient (J(w)) by a gravimetric technique. BCD, when present in the solution bathing the apical side of the bladder, inhibited the increase in J(w) caused by nystatin, a polyene antibiotic that acts by directly binding apical membrane cholesterol. When present in the basolateral bath, BCD inhibited the increase in J(w) caused by basolateral exposure to oxytocin (which binds membrane receptors and stimulates the synthesis of cAMP), but did not alter the response to theophylline (which inhibits hydrolysis of cAMP by cyclic nucleotide phosphodiesterase).

[Intestinal transplantation in pediatrics. Analysis of the first recipient series in Argentina].

The present is a retrospective analysis of all pediatric patients that underwent intestinal transplant from March 2006 to March 2010, describing demographics, indications, contraindications, clinical follow up and survival in a single center in Argentina. Based on the results shown one can conclude that intestinal transplant should be considered as a valid treatment for patients with intestinal insufficiency and complications related to parenteral nutrition. The results of our program are similar to those reported in the international Intestinal Transplant Registry.
