What a ridiculous, nasty post. Hopefully you will never be in such a position to make heart wrenching decisions like his parents have had to. Unnecessary post
I think they (the parents) have been both badly advised and, more than that, exploited - and it's evident (from the GOSH statement: link below) that Professor Hirano has acted in a less that honourable manner - the fact that he offered his treatment without either attending the patient in the latter stages or even bothered to read the material GOSH supplied that underpinned the prognosis is a scandal - the additional bombshell that he would have benefited financially from offering the treatment he advocated is hopefully something that he will be vociferously and loudly condemned for well into the future.
Were he to be licensed in the UK I would imagine the GMC would take avery dim view of his actions.

Interestingly (as a leftie) I thought Melanie Phillips' comment summed up the situation perfectly (bar her usual dig against anything left in the antepenultimate paragraph)
