What unfavourable oral sequel is associated with prolonged use of antibiotics in children?
**Core Concept**
Prolonged use of antibiotics in children can lead to an imbalance in the normal gut microbiota, resulting in an increased risk of oral candidiasis. This is due to the suppression of beneficial bacteria that normally compete with Candida species.
**Why the Correct Answer is Right**
The correct answer is related to the concept of "antibiotic-associated candidiasis" or "oral candidiasis," which is a type of fungal infection caused by Candida species. Prolonged use of antibiotics disrupts the normal balance of gut microbiota, allowing Candida to overgrow and cause infection. This is often seen in children, especially those taking broad-spectrum antibiotics.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because while antibiotic-associated diarrhea is a common side effect of antibiotic use, it is not directly related to oral candidiasis.
* **Option B:** This option is incorrect because antibiotic-induced thrombocytopenia is a rare side effect of antibiotic use, and it is not specifically related to oral candidiasis.
* **Option C:** This option is incorrect because antibiotic-associated Stevens-Johnson syndrome is a severe skin and mucous membrane disorder, but it is not directly related to oral candidiasis.
**Clinical Pearl / High-Yield Fact**
To prevent oral candidiasis in children taking antibiotics, healthcare providers often advise parents to maintain good oral hygiene, including regular brushing and flossing, and to use a soft-bristled toothbrush.
**Correct Answer: C. Antibiotic-associated oral candidiasis.
