Iodine deficeincy
Most common cause of hypothyroidism globally and suspect in cases where iodine is not added to diet.
Pheochromocytoma
Triad of sweating, headaches and palpitations. investigate with urinary metanephrines
Nephrogenic DI
Urine osmolality low after fluid deprivation and desmopressin
Prolactinomas
First line treatment with dopamine agonists (cabergoline, bromocriptine)
Prednisolone
Steroids increase the risk of osteonecrosis
Primary hyperaldosteronism
Symptoms include hypertension, headaches, muscle weakness and nocturia. Investigated with aldosterone/renin ratio
Klinefelter’s syndrome
Causes high LH and low testosterone
Wilm’s tumour and neuroblastoma
Refer any child with a palpable abdominal mass or unexplained enlarged organ very urgently to specialist
Primary hyperparathyroidism
Parathyroid adenoma may have normal PTH level
SGT2 inhibitors
Increased risk of urinary tract infection
Sulfonylureas
Often cause weight gain
Angiotensin II receptor blocker
Used first line in all black T2DM patients with hypertension
Diabetes blood pressure
Aim for 135/85 home readings
Metoclopramide
Can cause galactorrhoea
Adrenal venous sampling
After inconclusive CT AVS can be used to determine between unilateral adenoma and bilateral hyperplasia in primary hyperaldosteronism
Bilateral idiopathic adrenal hyperplasia
Most common cause of primary hyperaldosteronism
Pregabalin
Used in neuropathic pain with a history of benign prostatic hyperplasia
Adrenal insufficiency
Can occur on surgery after long term steroid use and needs IV hydrocortisone 100mg
Diabetic ketoacidosis
Hyperglycaemia and ketones, man aged with immediate IV fluids then insulin infusion and potassium
Glucocorticoids
Can induce neutrophilia
