EDITOR—A Grand Round discussed a boy who presented with cervical adenitis due to Mycobacterium paratuberculosisand later developed symptoms typical of Crohn's disease.1This sequence of events seemed unlikely to be unique; we therefore reviewed the full general practice medical records of 21 patients with Crohn's disease and 21 controls (matched for age, sex, and first letter of the surname) attending Sawston medical practice, a semirural practice of 12 500 patients.
