PPID: Equine endocrinology researchers revise guidelines for "Cushings" tests for horses

Equine Cushings Disease or pituitary pars intermedia dysfunction (PPID) has been easy to identify, with overt signs like a long coat. Underlying PPID is now being identified in younger horses and in horses that show none of the typical signs. Researchers say that an episode of otherwise-unexplained laminitis may be their first and only clue.
