RESUMO
CASE: Alcoholic ketoacidosis (AKA) usually occurs in patients with a history of prolonged alcohol abuse and recent binge drinking followed by abrupt cessation of alcohol consumption. OUTCOME: A 61-year-old man was brought to our emergency department. He had a history of eating barbecued beef with beer the previous night. He had unexplained hypoglycemia with high anion gap metabolic acidosis and fatty liver, and we strongly suspected AKA. After hydration with saline solution, dextrose, and thiamine, given i.v., his metabolic acidosis rapidly improved. A history of alcohol abuse and high serum ß-hydroxybutyrate concentration were subsequently confirmed, and the diagnosis of AKA was finally made. CONCLUSION: Our case suggests that a high-fat meal can induce AKA without abrupt cessation of alcohol consumption and that AKA should be considered when encountering patients with unexplained high anion gap metabolic acidosis with hypoglycemia and fatty liver, even if the past history of alcohol abuse is unknown.
RESUMO
A 72-year-old Japanese woman was admitted because of vomiting and abdominal pain. An enhanced computed tomography scan showed a small intestinal obstruction due to ileal wall thickening and multiple liver metastases. Her serum alpha-fetoprotein (AFP) level was high at 1671.9ng/ml. An ileocecal resection was performed. The histological diagnosis was AFP-producing small intestinal cancer resembling the primitive gut epithelium of a fetus. The present case suggested that even intestinal cancer could produce AFP.
