ENDO Flashcards
weight gain cold intolerance dry coarse skin/hair thinning eyebrows constipation menorrhagia lethargy
Hypothyroidism
hypothyroid symptoms with a firm, non tender goitre
Hashimoto’s thyroiditis
hypothyroid symptoms with a pain goitre and raised ESR
Subacute/De Quervain’s
lethargy, bradycardic, hypothermia
coma or seizures
myxoedema coma
management of myxoedema coma
emergency hospital admission
IV thyroxine and hydrocortisone
management of hypothyroidism
levothyroxine 50-100mg, start at 25mg for elderly/CVD
check TFTs every 3 months
ensure euthryoid before conceiving children/getting pregnant
treatment for subacute/De Quervain’s
thyroid scintigraphy = lowered iodine uptake
mx= aspirin/NSAIDs for pain
weight loss, heat intolerance manic/restless palpitations Increased sweating oligomenorrhoea anxiety/tremor pretibial myxoedema = erythematous, oedematous lesions
Hyperthyroidism
hyperthyroid symptoms with exophthalmos, ophthalmoplegia and pretibial myxoedema
Grave’s disease
Hyperthyroid & Scintigraphy reveal patchy iodine uptake
toxic multinodular goitre
Hyperthyroidism treatment
propranolol = control thyrotoxic symptoms
carbimazole (agranulocytosis risk - check WCC) - propyluracil in pregnancy
radioiodine Tx
Titrate and block
titrate down to the lowest dose for euthyroid = maintain euthyroid
block and replace
block T4 synthesis + give levothyroxine
fever >38°C tachycardic confusion and agitation N&V HTN, HF jaundice and abnormal LFTs
thyroid storm
triggered by infection, surgery, contrast exposure/CT, trauma
painless enlarge thyroid nodule
hoarseness and dysphagia
fever, weight loss and night sweats
Thyroid cancer
Ix for thyroid cancer
TFTs, Thyroid US
I131 scan = cold nodules
management for thyroid cancer
total thyroidectomy
radioactive I131 to kill residual cells + LT4
yearly thyroglobulin levels to detect any early recurrent disease
main form of thyroid cancer
papillary
others include follicular and medullary
abdominal pain renal stones depression bone pain unquenchable thirst may have peptic ulcers/constipation or pancreatitis
typically elderly females
hyperparathyroidism
pepperpot skull
PTH high
high calcium, low phosphate
hyperparathyroidism
management of hyperparathyroidism
definitive = total parathyroidectomy
tetany/twitching/cramps/spasms of muscle
numb, burning and paresthesia of mouth
Trousseau’s signs +ve = carpal spasm
Chvostek’s signs +ve = twitch on tapping parotid gland
prolong QT
chronic cases may present with cataracts and depression
hypoparathyroidism
low PTH
low calcium
high phosphate
primary hypoparathyroidism
low calcium
high phosphate
high PTH
pseudohypoparathyroidism
pseudohypoparathyroidism diagnosis
urine cAMP and PO4 after PTH infusion
management of hypoparathyroidism
alfacalcidol (vit d)
+ calcium supplements
> 7.5mmol/L total cholesterol
personal/family history of premature CHD (event before 60yrs)
familial hypercholesterolemia
familial hypercholesterolemia
high dose statins
primary prevention of hyperlipidemia
QRISK @ 40yrs = >=10%
>7.5mmol/L LDL
atorvastatin 20mg first line
secondary prevention of hyperlipidemia
80mg atorvastatin - aiming for a 40% drop in LDL
