Oh, interesting. I hadn't actually encountered that definition of acute. Looked it up. Seems like medical dictionaries lean towards defining acute as an opposite to chronic, while non-medical dictionaries include that and other definitions like "extremely sharp or severe; intense" - which is how I took it. Good to know, for talking to doctors.
