A child is presenting features of hyperparathyroidism. All of the following are true about him except
**Core Concept**
The child is presenting features of hyperparathyroidism, which is a condition characterized by an excess of parathyroid hormone (PTH) in the body, leading to hypercalcemia. This condition can result from various causes, including primary hyperparathyroidism due to parathyroid gland tumors or adenomas, secondary hyperparathyroidism due to vitamin D deficiency or chronic kidney disease, or tertiary hyperparathyroidism due to long-standing secondary hyperparathyroidism.
**Why the Correct Answer is Right**
Hyperparathyroidism can lead to various clinical manifestations, including bone resorption, kidney stones, and neuropsychiatric symptoms. The elevated levels of PTH stimulate osteoclasts to break down bone tissue, leading to an increase in serum calcium levels. Additionally, PTH can cause an increase in 1,25-dihydroxyvitamin D levels, which further contributes to hypercalcemia. The child's presentation of hyperparathyroidism symptoms is likely due to the effects of excess PTH on the body.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not provided, but it is assumed that one of the options A, B, C, or D is incorrect. We will provide explanations for options B, C, and D.
* **Option B:** This option is incorrect because it is not true about hyperparathyroidism. However, without the actual option, we cannot provide a specific explanation.
* **Option C:** This option is incorrect because it does not accurately describe the effects of hyperparathyroidism. However, without the actual option, we cannot provide a specific explanation.
* **Option D:** This option is incorrect because it is not true about hyperparathyroidism. However, without the actual option, we cannot provide a specific explanation.
**Clinical Pearl / High-Yield Fact**
One key point to remember is that hyperparathyroidism can lead to a range of clinical manifestations, including neuropsychiatric symptoms, bone resorption, and kidney stones. It is essential to consider the potential effects of excess PTH on the body when evaluating a patient with hyperparathyroidism.
