[Correspondence] The need to revise the Helsinki Declaration
In 2011, The Lancet published an Article (Dec 10, p 1997)1 on the first case of a transplant using a synthetic trachea seeded with the patient’s own stem cells. The senior author was Paolo Macchiarini, a thoracic surgeon working at the Karolinska University Hospital, Stockholm. Macchiarini performed another three transplantations with the same technique at the Karolinska. Since research misconduct was suspected and several of the authors of the 2011 article retracted their authorships, The Lancet added an expression of concern to the article in April, 2016.
