A reading and search of the Special Article titled "Internists and Adolescent Medicine"1 did not reveal the use of the name ephebiatrics for this branch of medical practice. Similarly, this name did not appear among the reference titles. Considering the remote and recent history of the naming of medical specialties and the continued disagreement concerning the desirability of even the term internal medicine, I would think that medical journals would be in the forefront of suggesting the use of existing terms that are clear and unambiguous. Furthermore, I would think that most children of the pertinent age group would rather make a visit to their family ephebiatrician than to their adolescent medicine doctor.
