Eleven-year-old Harry is complaining of a severe sore throat and gets to stay home from school. His pediatrician
prescribes a course of broad-spectrum antibiotics, and Harry feels much better
within a few days. However, some two weeks later, Harry has a dull, bilateral
pain in his lower back and his urine is a smoky brown color. On the basis of
Harry's signs and symptoms, diagnose his condition and draw the
relationship (if any) between his present condition and his earlier sore
throat.
