[Science and ethics, therapeutic misconception and mirage].

Medical practice changes constantly. Ethical imperatives are however incorrigible. How can we reconcile ethics, practice and progress? Some bioethicians argue that research and care should be disentangled to minimize the 'therapeutic misconception', a clinical propensity to believe that patients are the object of medical care, while in fact they are the subjects of a scientific experiment. On the contrary, we believe that clinical research should be an integral part of the good practice. A divorce between research and clinical practice leads to an incorrigible medicine, liable to the therapeutic mirage, that is the false belief that everything modern medicine can offer has been proved beneficial. But both therapeutic misconception and mirage are possible because of a misunderstanding of either research or clinical practice. In this essay we review ethical principles behind clinical trial methodology and attempt to reconcile ethics, science and clinical practice. Not only should clinical research be integrated to the good practice of medicine, it should also be part of training in our specialty.
