Transient nephrotic syndrome after anaesthesia resulting from a familial cryofibrinogen precipitating at 35 degrees C

Transient nephrotic syndrome, haematuria, and cryofibrinogenuria in a child after anaesthesia were found in association with a plasma cryofibrinogen that precipitated at 35 degrees C. Investigation of the family showed this to be a familial trait probably with dominant inheritance.
