No, it does not come up again because they dealt with that storyline. Disruptions in brain function after brain surgery are not uncommon. Foreman's brain just needed some time to recover and essentially remember how to do certain things that it was a little confused about. They showed us that in the next episode, where he was not allowed to touch the patients. As the episode went on, we saw him getting better and better.

I think that that's the best answer! I vote you best answer!
No, they have never mentioned it again later...I have found that strange too...usually things like that don't come out without a reason...maybe someone else have noticed something we missed...
