Tom, as you know, with hatchlings and youngsters it's difficult to medicate. I have had great success with using Lamisil ointment. It's used to cure jock itch among other things. I dry dock the turtles and apply some and keep them dry for 24 hours. Like Ken stated before, it's hard for me to tell you what to do because something could end up killing them. Unfortunatley even though we hear it ALL the time....getting them to a vet might be your best bet.
