Feature of scurvy in children include:
**Core Concept**
Scurvy is a disease caused by a deficiency of vitamin C (ascorbic acid), which is essential for the synthesis of collagen, a key component of connective tissue. In children, scurvy can lead to impaired growth and development, as well as increased susceptibility to infections.
**Why the Correct Answer is Right**
The correct answer is related to the fact that scurvy causes impaired collagen synthesis, leading to poor wound healing and increased risk of bleeding due to fragile blood vessels. Vitamin C is also necessary for the production of carnitine, which is important for fatty acid metabolism and energy production in cells. In children, scurvy can also cause anemia, due to impaired iron absorption and increased iron excretion.
**Why Each Wrong Option is Incorrect**
* **Option A:** Not a feature of scurvy. Scurvy does not primarily cause hyperglycemia.
* **Option B:** Not a feature of scurvy. Scurvy can actually cause impaired iron absorption, leading to anemia.
* **Option C:** A feature of scurvy, but not the most specific or characteristic one.
**Clinical Pearl / High-Yield Fact**
Scurvy is often seen in children who are fed a diet lacking in fruits and vegetables, or who have a restricted diet that excludes these essential food groups. Vitamin C deficiency can also be seen in children with gastrointestinal disorders, such as celiac disease or Crohn's disease, which impair nutrient absorption.
**Correct Answer:** C. Poor wound healing
