DEAR DOCTOR K: I'm 54 and have had Type 1 "childhood" diabetes since I was 7. A friend with diabetes heard about a new skin patch that automatically keeps a person's blood sugar in control -- no finger-sticks to check blood sugar, no needles for getting insulin. Can that possibly be true?
DEAR READER: It's not true yet, but I think it's coming. I'm glad you asked the question, because what I'll call "electronic skin patches" are starting to affect both medical care and research in many areas, not just diabetes.
