We used to have podiatrist and paediatrician, but podiatrists decided it was all too confusing, and changed to being known as chiropodists.

As synchronicity would have it, I was on the site of the NSW Podiatry Association the other day. I quote:

"The word "podiatry" changed from "chiropody" in the late 70s, and helped overcome the confusion with chiropractic. The word "podiatry" stems from the Greek podis (foot) and iatria (healing/physician)."

Seems foot doctors are fated to confusion...
