Cannabinoid products for pain management: recommendations from the São Paulo State Society of Anesthesiology.

There is growing interest in using cannabinoids across various clinical scenarios, including pain medicine, leading to the disregard of regulatory protocols in some countries. Legislation has been implemented in Brazil, specifically in the state of São Paulo, permitting the distribution of cannabinoid products by health authorities for clinical purposes, free of charge for patients, upon professional prescription. Thus, it is imperative to assess the existing evidence regarding the efficacy and safety of these products in pain management.

Randomized clinical study comparing active heating methods for prevention of intraoperative hypothermia in gastroenterology.

Objective: to compare the efficacy of three active heating methods in the prevention of intraoperative hypothermia in open gastroenterological surgeries.

Method: randomized clinical trial with a sample of 75 patients, whose initial body temperature measured by a tympanic thermometer. Esophageal temperature <36ºC was considered hypothermic.

Prognostic factors for hepatocellular carcinoma recurrence: experience with 83 liver transplantation patients.

Introduction: Orthotopic liver transplantation (OLT) is a rational therapeutic option for early-stage hepatocellular carcinoma (HCC) providing a potential cure and improving survival.

Methods: This retrospective study of a longitudinal cohort used an electronic database collected prospectively from September 1997 to May 2010. The variables were gender, age (years), and alpha-fetoprotein (AFP) level (ng/mL).

Pretransplant hyponatremia could be associated with a poor prognosis after liver transplantation.

Introduction: Predicting the prognosis of hepatic cirrhosis is the most accurate method to achieve a fair allocation among the liver transplant waiting list thereby reducing overall mortality rates.

Aim: To study the survival rates of recipients who undergo liver transplantation in association with hyponatremia rates.

Methods: This retrospective study used a prospectively collected database.

Portal vein thrombosis and liver transplantation: long term.

Obstruction of the portal vein may be related to constriction by malignant tumors or thrombosis associated with liver disease. We herein have reported our experience with patients undergoing liver transplantation with portal vein thrombosis (PVT) whose diagnosis was made intraoperatively. From September 1991 to May 2009, we studied 27/419 (6.
