Textbook Question
Chapter 23, Problem 14RQ
One diagnostic test to determine the cause of hypercortisolism is a dexamethasone suppression test. Dexamethasone blocks secretion of ACTH by the pituitary. The following table shows the results from two patients given a dexamethasone suppression test.
Can you tell from these results where the patients’ pathologies originate? Explain for each patient.

Diabetes insipidus has been identified in two males. One person did not have the condition until he had a stroke. The other had lived with the condition his whole life, and despite the existence of normal ADH receptors, it had never reacted to exogenous ADH. What might be the cause of the two men's diabetes insipidus? Provide your references.
Answer the following:
1.) an indirect agonist that mimics the action of epinephrine and norepinephrine and either stimulate release or block the reuptake of the naturally occuring sympathomimetics

"My Brother Calls Me 'Bug s"": A Case Study on the Endocrine System
Nineteen-year-old Krista waited impatiently as Dr. Weisman scribbled in his chart. She
hoped he was scribbling an explanation of what was wrong with her. She was tired of not
feeling like herself and tired of being so stressed about it. She was particularly tired of
how her eyes seemed to bulge outward, so much that her 10-year-old brother had started
calling her "Bug Eyes."
Dr. Weisman finally put down his pen and looked at Krista. "Well, your blood pressure
and pulse are elevated. You've lost weight without trying, you have difficulty sleeping,
you perspire more than usual and you've had continuing bouts of diarrhea. Those things,
combined with the swelling in the front of your neck, suggest that you may be suffering
from more than the stress of college life. I think we need to run some blood tests to check
your thyroid function."
Krista blinked in surprise. "All of those things can be caused by a…

- Cushing’s syndrome is a disorder that occurs when your adrenal glands release too much cortisol.Sometimes, Cushing’s is caused by a hormone-secreting tumor that leads to dysregulation of the hypothalamus-pituitary-adrenal gland axis. Below, are listed a few tests doctors perform to determine the specific cause of Cushing’s in each patient. Please read the description of the test and possible results and respond to the prompts below. 1 Measure blood levels of adrenocorticotropic hormone (ACTH). If ACTH levels are lower than normal, where is the tumor? How do you know? Remember, this person has high cortisol levels 2 Conduct a corticotropin-releasing hormone (CRH) stimulation test where you inject a shot of CRH. If this test results in a normal increase in ACTH levels, where is the tumor? How do you know? 3 Inject a very high-dose of compound that is a cortisol-receptor agonist. A few hours later measure levels of circulating ACTH. If the test results in normal…arrow_forwardThe symptoms of Cushing’s disease include abdominal obesity, hypertension, glucose intolerance (steroid diabetes), hirsutism, osteoporosis, polyuria, and polydipsia.
