Shaken baby syndrome in Switzerland: results of a prospective follow-up study, 2002–2007

Since the incidence of shaken baby syndrome in Switzerland was not known, we conducted a nationwide prospective follow-up study for a 5-year period (from 2002 to 2007). The data were collected through the Swiss Pediatric Surveillance Unit. Inclusion criteria were the presence, in a child under or equal to 6 years of age, more than or equal to two clinical symptoms (altered consciousness, convulsions, respiratory irregularities, and bulging fontanel), one eye finding (retinal hemorrhages, vitreous hemorrhages), one MRI/ CT finding (subdural hematoma, subarachnoid hematoma, and parenchymatous lesions), or history of shaking.
