Upon physical examination, you notice that his ankles and knees are red and swollen, and examination with a stethoscope reveals unusual palpitations (his heart is fluttering). You immediately order an EKG to check for signs of a heart attack, a CBC blood draw to check for signs of infection, a throat culture to check for the presence of Streptococcus, an X-ray of his legs to check for bone fractures or lesions, and a urine sample to check for bacterial contamination.A colleague of yours approaches you and says, “I have a theory: Perhaps this boy is suffering from an acute case of gout, the build-up of uric acid—a by-product of the break-down of DNA—in the joints.
