[Ketotifen poisoning in infancy?].

A male baby aged 3 1/2 months died about 3 hours after application of ketotifen due to chyme aspiration. Apart from a mycotic napkin rash the post-mortem examination did not show any other pre-existing pathological findings. When analysing blood samples toxicologically we observed a remarkably high concentration of ketotifen whereas the urine level was comparatively low. The morphological and toxicological findings are presented and discussed in differential diagnosis with reference to sudden infant death syndrome.
