A teenager is having diarrhea, rhinorrhea and sweating, most probable diagnosis is: AIIMS 10
## **Core Concept**
The symptoms described - diarrhea, rhinorrhea, and sweating - are indicative of an acute condition involving the autonomic nervous system. These symptoms can be associated with a cholinergic or muscarinic syndrome.
## **Why the Correct Answer is Right**
The correct answer, **.**, corresponds to an acute cholinergic syndrome or muscarinic crisis. This condition results from an overactivation of muscarinic receptors in the body, which can be caused by organophosphate poisoning, certain medications, or substances that mimic acetylcholine. The symptoms presented:
- Diarrhea: Increased muscarinic activity stimulates gut motility and secretion.
- Rhinorrhea: Increased muscarinic activity causes nasal glandular secretion.
- Sweating: Muscarinic receptors are involved in sweat gland stimulation.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option does not correspond to the symptoms described and does not fit with the muscarinic crisis or cholinergic syndrome.
- **Option B:** Similarly, this option does not relate to the symptoms provided and does not align with the clinical presentation of a muscarinic or cholinergic syndrome.
- **Option C:** This is the correct answer; therefore, it is not discussed here as incorrect.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is to recognize that organophosphate poisoning or exposure to certain pesticides can cause a cholinergic crisis. The symptoms can be remembered by the mnemonic "SLUDGE":
- **S**alivation
- **L**acrimation
- **U**rination
- **D**iarrhea
- **G**astrointestinal upset
- **E**mesis
## **Correct Answer:** .
