Multiple choice

Which of the following is a common cause of growth hormone deficiency in children?

  1. Pituitary tumor

  2. Hypothyroidism

  3. Cushing's syndrome

  4. Diabetes mellitus
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pituitary tumors are the most common cause of growth hormone deficiency in children. They can lead to a decrease in the production of growth hormone, which is necessary for normal growth and development.

Multiple choice

What is the most common cause of diabetes insipidus in children?

  1. Head injury

  2. Brain tumor

  3. Hypothyroidism

  4. Cushing's syndrome
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Head injury is the most common cause of diabetes insipidus in children. It can damage the hypothalamus or pituitary gland, which are responsible for the production of antidiuretic hormone (ADH). ADH is necessary for the kidneys to reabsorb water, so a deficiency of ADH can lead to diabetes insipidus.

Multiple choice

  1. Graves' disease

  2. Toxic adenoma

  3. Toxic multinodular goiter

  4. Subacute thyroiditis
