In this video Joel Topf looks at three types of potassium wasting nephropathies: Polyuria; distal RTA; and hypomagnesemia...and how each can lead to hypokalemia.
In this video Joel Topf looks at how you can easily differentiate between different types of diabetes insipidus.
In this video Joel Topf looks at acetazolamide and potassium-sparing diuretics; how to optimise your patients’ diuretic regimen; the advantages and disadvantages of each diuretic; and what to do when they don’t work.

Hypokalaemia: the most common electrolyte abnormality in hospitalised patients; mostly caused by drugs and GI disease
Hypernatraemia can be caused by a number of critical illnesses: water depletion (decreased intake, hypotonic fluid loss – renal/non-renal); solute excess (Na+ or other)
