Around the world, there is still a lot of current experience. What's happening, as in the U.K., is that the long-established expert is transferring the knowledge and training up an apprentice. However, to be an apprentice in this, you seem to be a professor of genetics to start with, or something of that order.
I think there is a trend towards bringing in the geneticists now, rather than the orthopaedic specialists, because there are, as Dr. Vargesson said, a number of genetic phenocopies of thalidomide—that is, genetic disorders that produce the same results. In saying that, most of what we dealt with were inquiries from people whose condition was very different from the normal thalidomide pattern. Our usual response to those people was that if they could produce evidence of their mother ingesting the drug, we would look at it. However, we're referring back to all the old reports from where it was known that mothers had taken the drug—that was definitely evidenced—and how their babies came out. None of those would have had transverse or unilateral reductions.
There are patterns, so you need a clinician with expertise, and that's what's happening in the different countries around the world.
