Question 1
A 10-year-old boy presents to the office, complaining of a painful, swollen area along his right jaw and neck. On physical examination, he is noted to be febrile and has diffuse tenderness over the right parotid gland. His laboratory tests include an elevated serum amylase. His parents elected not to vaccinate him. In this patient, based on the most likely diagnosis, which of the following is a complication of his disease?
nerve deafness
testicular torsion
Question 1 Explanation: 
The most likely diagnosis in this patient is mumps. It is endemic in most unvaccinated populations. The onset is characterized by pain and swelling in one or both parotid glands. The pain can be exacerbated by tasting sour liquids such as lemon juice. An elevated serum amylase level is common and coincides with the parotid swelling. Unilateral, rarely bilateral, nerve deafness is a complication of mumps that may be transient or permanent. Other complications include meningoencephalomyelitis, orchitis, epididymitis, pancreatitis, arthritis, and rarely thyroiditis and myocarditis.
