Doctors have called for a boycott of a conference that is to be chaired by a proved plagiarist, the BMJ reports (2009;339:b3545). The fifth annual meeting of the International Academy of Perinatal Medicine is being chaired by Asim Kurjak, who was found guilty of scientific misconduct in 2007. Zagreb University did not sanction him. Harvey Marcovitch, former chairman of the Committee on Publication Ethics, said that by attending speakers "threaten the integrity of science." Iain Chalmers, who originally exposed Kurjak, finds it "extraordinary that the perinatal research community is prepared to lionise a man guilty of scientific and professional misconduct."
