Question Severe pain in the muscles ???

A 3 year old boy is brought to the ER by his mother because of severe pain in the right leg after he fell from the porch 30 minutes ago. He has a 6 month history of intermittent pain in his legs at night. His mother adds that he cannot keep up with his peers on the playground. Evaluation shows a fracture of the right fibula. There is also gluteal muscle weakness bilaterally. Measurement of which of the following is most likely to confirm Dx?

A) ESR
B) Serum CK activity
C) Serum hydroxyproline concentrations (WRONG)
D) Serum Ig concentrations
E) Serum Rheumatoid factor titer

Default Answer B

Most likely it is the case of Polymyositis in which there is muscle pain and proximal muscle atrophy.

So answer would be B. Serum CK activity.
