Write answer in between .Q:A 2-year-old girl presented to the emergency department after a generalized tonic-clonic seizure that lasted one minute, an hour ago. She has been in good health since birth and has no history of convulsions in the past. She has been sick with an upper respiratory tract infection for the last 2 days, and her parents have been medicating her at home for a subjective fever. Her blood pressure is 10951 mm Hg, pulse rate is 180min, temperature is 38.9C 102.0F, and oxygen saturation is 98 on room air. The child is sleepy and ill-appearing. The cardiovascular, respiratory, and abdominal examinations are unremarkable. Blood glucose level is 50 mgdL. Three boluses of IV dextrose are given, but the patient remains drowsy. CXR is normal. After a few hours, her clinical condition deteriorates with associated respiratory failure that requires intubation and mechanical ventilation. Liver function tests reveal AST 3,000 UL, ALT 2,200 UL, and INR 3.0. Further testing ruled out hepatitis A, B, and C, and CMV infection. CT scan of the brain was normal. What is the most likely cause of her condition?? A: Hemosiderin deposition, B: Copper deposition, C: Ca2 efflux, D: Glutathione saturation, E: Decrease in hypothalamic set point,  <response>: This is a clinical vignette describing a 2-year-old girl who presented with a seizure and was found to have hypoglycemia. She was treated with IV dextrose but her condition deteriorated, requiring intubation. Lab tests showed very elevated liver enzymes and coagulopathy, with infectious causes ruled out. This presentation is most consistent with acute liver failure. The question asks about the most likely underlying cause.Choice A Hemosiderin deposition refers to iron accumulation and is not relevant here. Choice B Copper deposition can cause liver damage but there is no evidence for copper toxicity in this vignette.Choice C Ca2 efflux may relate to mitochondrial dysfunction but is vague and does not explain the acute liver failure.Choice D Glutathione saturation refers to depletion of glutathione, an antioxidant. This can occur in acetaminophen toxicity, which is a common cause of acute liver failure. Choice E Decrease in hypothalamic set point relates to body temperature regulation and is unrelated to the clinical scenario.D: Glutathione saturation
