Sudden death in infancy syndrome in Western Australia.

The objects of the Western Australian investigation into the sudden death in infancy syndrome are stated. Evidence is presented which suggests that these children are subject to an asphyxial mode of dying. It is postulated that anaphylaxis, due to hypersensitivity to the house dust mite, and possibly other allergens, is implicated, with the respiratory system as the target organ. A family counselling service is described.
