65 yr old patient presented with history of loose stools of nearly 2 days duration. Found to be diabetes on admission. Started on antibiotics and stool forming agents. 2nd day of admission this patient is found to be a bit dull and quite an amount of oral secretion. In next half an hr or so he arrests , he's put on ventilator and found to have bilateral pin point nonreactive pupils.
Investigation so far reveals his potassium is 2.9 . Rest of his routine investations were normal. Any differential diagnosis? Well eventually I found out the cause.. but just to keep it interesting lets start off with some differentials and I'll go on adding further clues.
