Deciphering medical abbreviations in outpatient records

I was wondering what those abbreviations actually stand for. Ames i AS I was looking through some gynecologist's outpatient charts today. It’s a bit of a mess. On one chart, it says, "Follow-up with results at Ames." Then on another one, it reads, "Follow-up with results at AS." Just inconsistent notation for the sake of it, I suppose.
I'm lost. What exactly are we talking about here?
