What does PTH act on to do what?
In which two ways does the kidney maintain calcium levels?
- Vitamin D activation acts to increase calcium levels –> CKD = hypocalcaemia
- PTH stimulates kidneys to reabsorb calcium –> CKD = hypocalcaemia

How much glucose is given in OGTT?
Two investigations for acromegaly?

Give three classes of drug that can be used to treat acromegaly?
Give an example of a somatostatin analogue.
Give an example of a GH antagonist.
Give an example of a dopamine agonist.
What’s the mnemonic for remembering the symptoms of Addison’s?
Investigations for hyperaldosteronism? Which is first line?
How would you test for Cushing’s syndrome?
How would you test for Cushing’s disease and what result would you look for?
How would you test for adrenal Cushing’s and what result would you look for?
How would you test for ectopic ACTH Cushing’s and what result would you look for?
Give an example of an alpha blocker that could be used to manage pheochromocytoma?
Give an example of a mineralocorticoid.
Give an example of a glucocorticoid.
Which layer of the adrenal cortex are androgens produced?
Where in the adrenal glands is adrenaline produced?
What are the layers of the adrenal cortex and what’s produced in each layer?
Give two diagnostic tests for pheochromocytoma. Which one is gold standard?
First, second and third line treatment for DKA?
Diagnostic criteria for DKA?
What anion gap is seen in DKA?
What electrolyte do you need to closely monitor in DKA?
What should you think of if you see low sodium and high glucose in DKA?
What serum osmolality would confirm pseudohyponatraemia in DKA?
What’s the medical term for heavy menstrual bleeding and is it associated with hyper or hypothyroidism?
Difference between endocrine and exocrine glands?
- Endocrine: hormones/substances secreted directly into bloodstream
- Exocrine: hormones/substances secreted into a ductal system usually leading to an epithelial surface
Other than Addison’s, give three causes of primary adrenal insufficiency.
Other than long term steroid use, give three causes of secondary adrenal insufficiency.
How does hyperglycaemia lead to increased insulin production on a cellular level?
- Increased glucose uptake by beta cells
(GLUT2 receptors) - Increased ATP production due to glucose metabolism
- K+ channels shut due to increasing ATP, causing cell membrane depolarisation
- Ca2+ channels open, influx
- Exocytosis of insulin containing vesicles
Give two microvascular and two microvascular complications of TIIDM.
Micro - retinopathy, nephropathy, neuropathy
Macro - cardiovascular disease, cerebral vascular disease, PAD
What three antibodies are found in Grave’s disease?
Three most common types of thyroid cancer?
Give five causes of hypothyroidism.
What antibodies are found in Hashimoto’s thyroiditis?
What do C-cells in the thyroid secrete?
What’s a key red flag side effect of carbimazole?
- Sign of infection, commonly sore throat
(Carbimazole suppresses bone marrow production so may lower WBC count)
Give four treatments of Grave’s
What can be given to treat hypothyroidism?
Synthetic levothyroxine / T4
What’s the most common antibody type in autoimmune diseases?
IgG
Apart from bones, stones, moans, groans what are three other symptoms of hypercalcaemia?
- polydipsia
- polyuria
- malaise
What test can be done for carcinoid syndrome?
What’s the gold standard for diagnosis of carcinoid syndrome?
- Serum chromogranin-A + octreoscan
Is pre-tibial myxoedema pitting or non-pitting?
Non-pitting
Normal serum potassium range?
What epithelium lines the vas deferens?
pseudostratified columnar epithelium with stereocilia
Give two causes of hypercalcaemia other than MM and hyperparathyroidism.
Pre-diabetic HBA1c range?
42-47
Most common cause of iodine deficiency in developing vs developed countries?
Developed - Hashimoto’s
Developing - Iodine deficiency
Main electrolyte imbalance caused by SIADH?
Hyponatraemia
Drug used to treat hyperthyroidism and its MOA?
- Carbimazole
- Inhibits TPO
Two signs present in hypocalcaemia?
- Chovstek’s sign (tap facial nerve)
- Trousseau’s sign (blood pressure cuff <20mmHg above systolic, 5 minutes, claw hand forms)
Gold standard for diagnosis of carcinoid syndrome?
Serum chromogranin A + octreoscan
Micro and macrovascular complications of TIIDM?
Micro - retinopathy, neuropathy, nephropathy
Macro - CVD, CVD, PAD
(2nd CVD stands for cerebral vascular disease)
First line investigation for hyperaldosteronism?
Difference between a direct and indirect Comb’s test?
- Direct comb’s test detects antibodies stuck to the surface of RBCs (autoimmune haemolytic anaemia)
- Indirect comb’s test tests for antibodies against foreign RBCs. Used before blood transfusions.
