Professor Rolando Cimaz (Associate Professor at the University of Florence and Head of Pediatric Rheumatology at Meyer Children Hospital) makes a point about Behcet's disease, quite a rare disorder that in certain populations can be very frequent (Turkey, for example); it is characterized by inflammation of blood vessels and it is rare in pediatric age and in the elderly, and affects women preferentially. Rarely, Behcet's disease can have a very serious outcome.
