Postbariatric Surgery Hyperammonemia: A Rare Cause of Encephalopathy.

Hyperammonemic encephalopathy is an under-recognized and potentially fatal complication of Roux-en-Y gastric bypass surgery. We present a case of a 42-year-old woman with no known history of liver disease who experienced worsening encephalopathy 1 year after bariatric surgery. She presented with elevated ammonia and severe encephalopathy requiring intubation.

Peripheral venous bicarbonate levels as a marker of predicting severity in acute pancreatitis: a retrospective study.

Introduction: Acute pancreatitis is an inflammatory process of the pancreas, which can range from mild, self-limited disease to severe disease potentially resulting in death. Although overall mortality has decreased, the incidence of acute pancreatitis is increasing. Severe episodes of acute pancreatitis are more likely to result in prolonged hospitalisation and increased mortality.
