In medicine, there are many different disease entities with mysterious-sounding names. Wegener's granulomatosis, fish odour disease or Burkitt's lymphoma are just a few examples. An entity with also a rather unusual name, found predominantly in children, is Ondine's curse. This problem is not talked about much, which is a pity, as it can lead to the death of a child even very shortly after birth and can happen during... sleep.
