Antimigration versus conventional fully covered metal stents in the endoscopic treatment of anastomotic biliary strictures after deceased-donor liver transplantation.

Introduction: Migration of fully covered metal stents (FCMS) remains a limitation of the endoscopic treatment of anastomotic biliary strictures (ABS) following orthotopic liver transplantation (OLT). The use of antimigration FCMS (A-FCMS) might enhance endoscopic treatment outcomes for ABS.

Methods: Single center retrospective study.

Changes in peripheral blood mononuclear cells glutamine synthetase mRNA after exercise in healthy volunteers: exploring an alternative proposal for non hepatic ammonia metabolism.

Background: Glutamine synthetase (GS) plays a central role in the inter-organ metabolism of ammonia and hepatic encephalopathy. The main objective of the present work was to disclose the possible effect of exercise on GS mRNA expression in peripheral blood mononuclear cells (PBMC) within a group of healthy volunteers.

Material And Methods: PBMC were studied instead of skeletal muscle because of ethical concerns.

Validation of the psychometric hepatic encephalopathy score (PHES) for identifying patients with minimal hepatic encephalopathy.

Background: The psychometric hepatic encephalopathy score (PHES) is a battery of neuropsychological tests used in the diagnosis of minimal hepatic encephalopathy (MHE).

Aim: The aim of this study was to construct and validate a dataset of normal values for the PHES.

Methods: Volunteers and patients with cirrhosis with and without low-grade overt hepatic encephalopathy (OHE) were enrolled.

Autoimmune hepatitis with giant-cell transformation.

Background/aims: Giant-cell hepatitis (GCH), also known as postinfantile or syncytial giant cell hepatitis, is a frequent pattern of liver injury in the neonate, primarily seen in the first three months of life. Few cases in adults have been reported, some of them associated to autoimmune diseases such as autoimmune hepatitis.

Methods: We present a case of autoimmune hepatitis with giant cell transformation in a 39 year old male with polyarthritis.

Pathophysiology of ascites and dilutional hyponatremia: contemporary use of aquaretic agents.

Ascites, the most common complication of cirrhosis, is associated with a poor quality of life, an increased risk of infection, and renal failure. Twenty percent of cirrhotic patients have ascites at the time of diagnosis, while 30% and 50% will develop ascites by 5 and 10 years, respectively. There are several factors that contribute to ascites formation in cirrhotic patients, these include splanchnic vasodilatation, arterial hypotension, high cardiac output, and decreased vascular resistance.

[Evaluation of coronary flow by means of PET in the Mexican population without coronary artery disease].

Unlabelled: Coronary artery disease (CAD) represents the principal cause of morbidity and mortality in our environment. Positron emission tomography (PET) is a new technique in our country that allows the assessment of myocardial perfusion and the absolute quantification of the coronary blood flow (CBF) through the utilization of radiotracers using the same criteria employed in conventional nuclear cardiology. CBF normal values have been determined in other populations around the world.
