we test all type 1 diabetics for which disease, even if they don’t have symptoms as the conditions are often linked
coeliac disease
anti-TTG and anti-EMA antibodies are which kind of immunoglobulin (IgA-E?)
IgA
remember to test for total IgA levels to exclude IgA deficiency
What can the causes of renal impairment be split into
pre renal
renal
post renal
if you come across a patient in the exam with a combination of acute renal failure and haemoptysis, what two conditions are you thinking of
good pasture syndrome
granulomatosis with polyangitis (aka wagerers granulomatosis
what is the difference between Goodpasture syndrome and granulomatosis with polyangiitis (AKA Wegener’s granulomatosis)
good pastures is associated with anti-GBM antibodies
Wegeners is associated with ANCA
most common cause of nephrotic syndrome in
children
adults
minimal change in children
focal segmental glomerulosclerosis in adults
what is the most common cause of primary glomerulonephritis
IgA nephropathy aka burgers disease
muddy brown casts found on urinalysis is a pathognomonic finding specific to which kind of kidney disease
acute tubular necrosis
type 4 renal tubular acidosis
- most common caused by reduced aldosterone
name some reasons that this can be due to
adrenal insufficiency medications such as ACE inhibitors and sprionolactone SLE diabetes HIV
what is the management of type 4 tubular acidosis
fludrocortisone
sodium bicarbonate and treatment of the hyperkalaemia may also be required
what is the most common cause of haemolytic uraemia syndrome
toxin produced by the bacteria e coli called the shiva toxin
shigella also produces this toxin
the use of antibiotics and anti motility agents such as loperamide to treat gsatronteritits increases the risk of developing HUS too
you should suspect rhabdomyolysis in patients with
crush injury
trauma
prolonged immobilisation
excessive sweating
name the main medications that cause hyperkalaemia
Aldosterone antagonists (spironolactone and eplerenone) ACE inhibitors Angiotensin II receptor blockers NSAIDs Potassium supplements
name the main conditions that cause hyperkalaemia
Acute kidney injury Chronic kidney disease Rhabdomyolysis Adrenal insufficiency Tumour lysis syndrome

Small Cell Lung Cancer
what are the 3 most dangerous aspects of DKA
dehydration
potassium imbalance
acidosis
what is the mnemonic for treating DKA
FIG-PICK
F – Fluids – IV fluid resuscitation with normal saline (e.g. 1 litre stat, then 4 litres with added potassium over the next 12 hours)
I – Insulin – Add an insulin infusion (e.g. Actrapid at 0.1 Unit/kg/hour)
G – Glucose – Closely monitor blood glucose and add a dextrose infusion if below a certain level (e.g. 14 mmol/l)
P – Potassium – Closely monitor serum potassium (e.g. 4 hourly) and correct as required
I – Infection – Treat underlying triggers such as infection
C – Chart fluid balance
K – Ketones – Monitor blood ketones (or bicarbonate if ketone monitoring is unavailable)
