Dr Nicky Cassell Diagnosing Hyperadrenocorticism. Dr Sandy May Treatment and Monitoring of treatment for hyperadrenocoreticism. Dr L van der Merwe & Dr Marlies Bohm Proteinuria and Hypertension in HAC. Dr A Zambelli 1. Which one of the hormones listed below is NOT produced by the adrenal gland. a. Cortisol or one of the precursors b. Aldosterone c. Sex hormones d. Growth Hormone e. Adrenalin 2. Which one of the following statements is NOT one of the guidelines used to decide to surgical remove an adrenal masses? a. Masses that are larger than 3cm. . b. Masses which show ultrasonographic signs of malignancy. c. Masses which are functional. d. Masses which show invasion of the surrounding blood vessels. e. Masses which show metastases to the liver. 3. Which one of the following statements regarding ultrasonographic evaluation of the adrenal glands is INCORRECT? a. The glands are typically uniformly hypoechoic. An outer hypoechoic rim and hyperechoic inner zone may be differentiated. b. The cut-off for maximum adrenal gland size in the dog is 0.74mm for either the cranial or caudal pole and is highly sensitive and specific for a diagnosis of HAC. c. Up to 25% of dogs with PDHcan have normal adrenal gland size on ultrasound and some healthy dogs will have adrenal glands larger than the recommended cutoff values. d. In some patients with PDH there may be asymmetrical enlargement due to nodular hyperplasia and it may be difficult to distinguish from an adrenocortical adenoma. e. Masses ≥ 2.0cm and/or showing mineralisation are considered likely to represent a malignant lesion. 4. Which one of the following statements regarding the ACTH stimulation test in dogs is INCORRECT? a. The baseline cortisol concentration is irrelevant. b. A post stimulation concentration of >600nmol/l is considered highly specific and diagnostic of hyperadrenocorticism in the dog. c. A big advantage of this test is in distinguishing between iatrogenic and spontaneous cushings disease. d. It is the only test used for monitoring response to treatment. e. It does not distinguish between PDH and ADH. 5. Which one of the following statements regarding the Low dose Dexamethasone suppression test (LDDST) is INCORRECT? a. The LDDST is a test used to differentiate ADH from PDH . b. The LDDST is more sensitive than the ACTH stim test overall. c. The LDDST is more sensitive than the ACTH stim test diagnosing PDH. d. The LDDST is more sensitive than the ACTH stim test for the diagnosis of functional adrenal neoplasia. e. The LDDST is a screening test for hyperadrenocorticism.
