Agreement: I Agree Body: Dear Editor The news article by Owen Dyer is an important contribution It however misses the key fact that the Lancet was alerted soon after the original publication in 2006 (Bateman et al 2008) in which we showed that other reports of this case by the same authors included data on paracetamol concentrations in the baby that were physiologically impossible in a breast fed baby. This debacle could have been avoided if the original report had been properly assessed and suitable responses made to our letter to the Lancet originally sent to their journal in early 2007, but only published many months later. The lesson learned from this tale show how easily misinformation can influence practice, and emphasises the problem of using a single case report to alter health policy Yours etc Ref Bateman DN, Eddleston M, Sandilands.
