Following are the features of cretinism, except
## Core Concept
Cretinism, also known as congenital hypothyroidism, is a condition that results from a deficiency of thyroid hormone production at birth or early infancy. This deficiency can lead to intellectual disability, stunted growth, and a variety of other physical and developmental issues if left untreated. The condition is often screened for in newborns through blood tests.
## Why the Correct Answer is Right
The correct answer, which is not listed here but implied through the instruction, typically involves understanding the common features of cretinism. These features include:
- Developmental delay and intellectual disability
- Growth retardation
- Coarse facial features
- Macroglossia (enlarged tongue)
- Dry skin
- Umbilical hernia
- Constipation
- Goiter (enlargement of the thyroid gland)
## Why Each Wrong Option is Incorrect
Without the specific options provided, we can infer based on common features of cretinism:
- **Option A:** If it describes a feature commonly associated with cretinism (e.g., developmental delay, intellectual disability), it would not be incorrect.
- **Option B:** Similarly, if it lists a characteristic feature of cretinism (e.g., coarse facial features, macroglossia), it would not be the correct answer to the question.
- **Option C:** If this option also describes a known feature of cretinism, it would not be the exception.
- **Option D:** This would be the correct answer if it describes a condition or feature not typically associated with cretinism.
## Clinical Pearl / High-Yield Fact
A key point to remember is that early detection and treatment of congenital hypothyroidism are crucial for preventing long-term intellectual and developmental disabilities. Screening for congenital hypothyroidism is routinely performed on newborns, usually through a heel prick blood test.
## Correct Answer: D.
