Attached is an interesting case of a 21 year old man presenting to his GP on 23rd Dec 2011 with a skin rash, otherwise fit and healthy. His biochemistry revealed an apparent hypokalaemic alkalosis with hyponatraemia. He was admitted to hospital where he improved rapidly with IV saline and potassium. He was discharged on Christmas Day with Sando K supplements.
There is little to note from previous history and biochemistry from 2009 appeared normal. Despite a number of investigations, the reason for the derangement in electrolytes remains a mystery.
A summary of his results is attached, including his urine electrolytes which are also unusual. Any opinions on the cause would be appreciated.
Many thanks,
