A patient was found to have pink coloured skin and mucosa, bitter almond smell from breath and frothy discharge. Cause of death in this patient;
**Core Concept**
The patient's symptoms, including pink colored skin and mucosa, bitter almond smell from breath, and frothy discharge, are indicative of a specific metabolic disorder that leads to a distinct cause of death.
**Why the Correct Answer is Right**
The patient's symptoms are characteristic of cyanide poisoning. Cyanide inhibits the enzyme cytochrome c oxidase in mitochondria, which is essential for cellular respiration. This inhibition leads to a rapid decrease in ATP production, causing cellular asphyxiation. The bitter almond smell is due to the release of cyanide from the breakdown of amygdalin in almonds. The pink coloration of the skin and mucosa is due to the formation of methemoglobin, which is a result of the excessive production of methemoglobin by the enzyme cytochrome b5 reductase. The frothy discharge is likely due to the release of cyanide from the breakdown of various cyanogenic glycosides in the body.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the patient's symptoms.
* **Option B:** This option is not a cause of death related to the patient's symptoms.
* **Option C:** This option is not a correct cause of death in this scenario.
**Clinical Pearl / High-Yield Fact**
In cases of cyanide poisoning, the treatment of choice is hydroxocobalamin, which binds to cyanide to form cyanocobalamin, a harmless compound that can be excreted by the kidneys.
**Correct Answer:** C. Cyanide poisoning.
