Consider the following scenario: During routine screening, an asymptom
atic man is found to have an abnormal alanine amino-transferase (ALT)
level and, subsequently, to have chronic hepatitis C. Because his phys
ician is anxious about the possibility of the development of cirrhosis
, the man is given interferon. During the months of therapy, the patie
nt (for now he truly has become a patient) displays a variety of drug-
related symptoms (including thyroid disease) and spends several thousa
nd dollars in personal and third-party funds. The AZT level normalizes
, and the physician breathes a sigh of relief. Unfortunately, the pati
ent spends the rest of his life taking thyroid medication. Exactly who
m did the physician treat?
