b. Men are more likely to develop Cushing’s syndrome
c. The incidence of Cushing’s syndrome is distributed equally between sexes
a. Women are more likely to develop Cushing’s syndrome
Which of the following are NOT causes of Addison’s disease?

b. Adrenal Adenoma
c. Glucocorticoid treatment (iatrogenic)
d. Increased ACTH-RH secretion
e. Ectopic ACTH production
c. Glucocorticoid treatment (iatrogenic)
Which of the following statements best describes a toxic thyroid adenoma?
a. Inflammation of the thyroid gland due to lymphocytic infiltration causing stored thyroid hormones to be released into the circulation leading to hyperthyroidism.
b. A malignant tumour of the thyroid gland which produces excessive amounts of thyroid hormones. These arise from the follicular cells of the thyroid gland.
c. An autoimmune disease directed against thyroid stimulating hormone (TSH) receptors. The autoantibodies stimulate the TSH receptors causing increased T3 and T4 production
d. A benign tumour of the thyroid gland which produces excessive amounts of thyroid hormones. These arise from the follicular cells of the thyroid
d. A benign tumour of the thyroid gland which produces excessive amounts of thyroid hormones. These arise from the follicular cells of the thyroid
Which of the following statements correctly describes the pathophysiology of Cushing’s disease?
a. Cushing’s disease results from a benign pituitary adenoma secreting excess levels of cortisol.
b.
Cushing’s disease results from a benign adrenal adenoma secreting excess ACTH. High levels of ACTH in turn cause increased production of cortisol from the adrenal cortex.
c. Cushing’s disease results from a benign pituitary adenoma secreting excess ACTH. High levels of ACTH in turn causes increased production of cortisol from the adrenal cortex.
d. Cushing’s disease results from a benign adrenal adenoma secreting excess levels of cortisol.
c. Cushing’s disease results from a benign pituitary adenoma secreting excess ACTH. High levels of ACTH in turn causes increased production of cortisol from the adrenal cortex.
What is the most common cause of hyperthyroidism?
a. Thyroiditis
b. Toxic multinodular goitre
c. Grave’s disease
d. Toxic thyroid adenoma
c. Grave’s disease
