There has been recent criticism of Chinese stem cell treatment for a great number of diseases that they are advertising that it has been successful. I see no rationale for the treatment at the moment. There is a component of autoimmune disease as a pathogenic factor in RSD but there are better ways to suppress this aspect of the problem than stem cell procedures. I rarely see ketamine fail in high doses(coma). It does fail in about twenty percent of patients with subanesthetic doses. There are other treatments and drugs on the horizon that may be effective. It is always a tough problem and we certainly do n ot know all of the answers.

Best regards,
