title: Infantile hypertrophic pyloric stenosis in Greater Manchester.
abstract: An "unprecedented" rise in the incidence of infantile hypertrophic pyloric stenosis (IHPS) was reported from the Central Region of Scotland in 1979. Examination of statistics from Greater Manchester showed a similar trend in some district health authorities but not others. Possible explanations are examined but future research is required. Hospital Activity Analysis can provide a useful tool for such research.
