Since it is protected i would not worry abbout it,
While it's possible, the chances are a lot lower since you used protection. Syphilis is not that common, so that wouldn't be a big concern for me. If you already have herpes type 1 (think cold sores), and she didn't have an outbreak, then you wouldn't get it again in a different location. If she did have an outbreak, the chances of you getting it genitally are a lot lower than if you didn't, but you don't mention any sores on her mouth, so I'm guessing she didn't.
There is no risk from her touching any part of you with her hand.
So in summary - possible, yes - likely, no.
