Diabetic ketoacidosis following mumps.

A-13-year-old girl presented with diabetic ketoacidosis with convincing clinical signs of parotitis (fever, drooling of saliva, inability to swallow with development of bilateral parotid swelling) and pancreatitis (fever, abdominal pain and vomiting), along with high serum amylase and positive mumps IgM titer. This suggests that mumps virus may have been the causative factor, probably as a result of concomitant involvement of the pancreas.
