I think we have to appreciate that in the last ten to twenty years, in some parts of the world, very much including the USA, any formal distinction between medical science and either crackpot ventures, or fraud, or both has disappeared. Things have changed out of all recognition. Just as people have talked of countries becoming banana republics we now have banana medicine.
In amongst that there are units delivering treeatments based on excellent science and reliable clinical evidence but even in the UK I sense my colleagues involved in medicine are beginning to lose the will to do things properly. At least for the moment populism has won.
