Sudden infant death syndrome (SIDS) following administration of honey is due to: MAHE 12
## Core Concept
Sudden Infant Death Syndrome (SIDS) is a sudden, unexplained death of an infant younger than one year of age that doesn't have a known cause even after a complete investigation, including an autopsy. Certain risk factors and associations have been identified, including prone sleeping position, maternal smoking, and exposure to certain substances.
## Why the Correct Answer is Right
The correct answer, **C. Clostridium botulinum toxin**, is linked to SIDS through the mechanism of botulism. Honey can contain spores of *Clostridium botulinum*, which, when ingested, can germinate in the infant's gastrointestinal tract and produce toxin. This toxin causes botulism, a condition that can lead to muscle weakness, paralysis, and respiratory failure. Infants are particularly susceptible because their gastrointestinal tracts are still developing, and they have not yet acquired the stomach acid and gut flora that can help protect against *C. botulinum* spores. The toxin can cause a form of botulism known as "infant botulism," which is a recognized risk factor for SIDS due to its potential to cause respiratory failure.
## Why Each Wrong Option is Incorrect
**Option A:** This option is incorrect because it is not specified and does not directly relate to known causes of SIDS or the effects of honey consumption.
**Option B:** This option is incorrect as it is not specified and does not relate to the known association between honey consumption and SIDS.
**Option D:** This option is incorrect because it is not specified and does not have a known association with SIDS or the consumption of honey.
## Clinical Pearl / High-Yield Fact
A critical clinical pearl is that **infants under one year old should not be given honey** due to the risk of infant botulism. This condition can present with nonspecific symptoms such as lethargy, poor feeding, and constipation, progressing to more severe signs like muscle weakness and respiratory distress. Parents and caregivers should be advised about the risks of honey and the importance of safe feeding practices.
## Correct Answer: C. Clostridium botulinum toxin.
