Endocrinology Flashcards
pain in thumb, index finger and forearm
tingling in the arm
what is it ?
carpal tunnel syndrome
hypothyroidism
what is bilateral adrenal hyperplasia
common form of secondary hypertension
patient will be hypertensive but have a low k+ level
features of SIADH
- low serum osmolarity
- high urine osmolarity
- high urine sodium
parathyroidism
the parathyroid hormone PTH is released by the parathyroid gland
has calcium and vitamin D receptors
when PTH is released
- renal phosphate exertion increases
- plasma calcium increases
- absorption of calcium in the gut increases
hyperparathyroidism - impacts
major cause of hypercalacaemia
primary hyperparathyroidism - mainly due to cancer
secondary - CKD causes calcium levels to drop so PTH gets raised to compensate for this
what is the most common cause of hypokalaemia?
hypothermia
- causes low levels of potassium due to a trans cellular shift of potassium when body temperature is low
- it is the most common reversible cause of cardiac arrest
- give patient potassium
what is antiphospholipid syndrome
when the immune system accidentally makes antibodies which attack tissues
this causes blood clots in the arteries and veins
can cause miscarriage in pregnancy
which medications can cause Cushings syndrome
corticosteroids like prednisolone can cause too much cortisol
which medication can cause hyperkalaemia
spironolactone - it is a potassium sparing diuretic
which medication can cause hyponatraemia
omeprazole
PPI
PPIs can affect the normal function of the kidneys and therefore affect the electrolytes
they can also affect ADH
what are the side effects of carbimazole - a hyperthyroidism drug
it can cause neutropenic sepsis
so always check FBC
what is hyperaldosteronism
it is when the adrenal glands release too much aldosterone
it presents with high blood pressure and low potassium
symptoms of worsening palpitations and tremors. He is found to have a goitre with a bruit and is referred to the Endocrinologists. His blood test reveal that he has developed thyrotoxicosis
what is the drug?
amiodirone
it has a high iodine content
what is serotonin syndrome
it is when there is too much serotonin in the blood
this can cause symptoms such as diarrhoea
tremors
mental state changes eg confusion
what is addinosinan crisis
when someone takes steroids long term and then suddenly stops - the body naturally stops making steroids because of the external input of it
when steroids are stopped, there is a sudden decrease in steroids
causes the crisis
low aldosterone
low sodium
high potassium
what is the management for addisonian crisis
IV hydrocortisone - increase glucocorticoids which increase serum cortisol
What is the investigation for Cushing’s disease?
Low-dose dexamethasone suppression test
what are the symptoms of Addisons disease
GI symptoms
hypotension
fatigue
What infections can be a cause of Addisons disease
TB
