The husband is being treated for coronary artery disease and tension headaches. Today, he mentions that he "cannot get an erection" even when he feels sexual desire. He adds that he still finds his wife physically attractive and that they are mutually compatible in every respect. This recent development has been causing him significant anxiety and has been a source of concern for his wife. After ruling out medical and psychological causes for his erectile dysfunction by taking a detailed history and pursuing a thorough workup, you agree to his request that he be started on sildenafil. One week later, his wife places an urgent call to your office, reporting that her husband developed severe chest pain "after taking the new medication you prescribed." An EKG done in the emergency department reveals new inferior wall ischemia.

Physical examination demonstrates pallor and hepatosplenomegaly. An extensive workup indicates that the girl is suffering from acute lymphoblastic leukemia, and her parents are informed that chemotherapy will be necessary.
