No, and the article doesn't say that. A "physician" is a 'Doctor of Medicine', a medical doctor.
A 'doctor of internal medicine' strikes me as an uncommon lay description, not an official designation. In fact, I have rarely, if ever, heard the phrase 'a doctor of internal medicine'. (at least not among physicians in Canada)
A physician that specializes in general internal medicine is called an 'internest'.
Thank you.
Google for "a doctor of internal medicine" gets 170,000 hits.
I am not sure whether it is only a lay description.
Students: We have free audio pronunciation exercises.
Then maybe I should say it's a description directed toward lay people. Medical people say "internest".
OneLook (all dictionaries online: http://www.onelook.com/ ) offers no definition for the word internest.:
(and google search for it is a mess. It is a question that people outside of Canada would use it)

My apology! The correct spelling is 'internist'. Emotion: embarrassed Now google it.

Considering how common the "ist" suffix is, the spelling part of my brain was clearly fast asleep.Emotion: sleep
