OK... you and this user board are a GREAT help and resource to the user board and for me (non-doctor just trying to help the doctor my wife works for). I feel compelled to chime in from a totally non-medical view.
1. I've been following the Penn State football child-abuse scandal. It appears that at least a few folks in power had the chance (in addition to others without power) to stop this 14 year mess. But, no one did, for fear of the reputation/legacy of Penn State football, and for others, their jobs.
2. I don't know if your situation can be considered "child abuse" or "child neglect", but if you think it even touches on this, seems like you've gotta do something. The worst thing to happen is if everyone stands aside, and something dreadful happens to this kid, which could have been prevented. I understand that this is a "family matter", but I think professionals should be able to step in at some point.
I remember when my son (about 9 years old at the time) had a strain in his neck, and I took him to the pediatrician. He examined my son rather carefully, and asked some pointed questions. Turns out, he was looking for signs of child abuse. I think if he saw anything, he would tell me, then report the incident.
As I've mentioned above, I don't know if your situation can be considered to be child abuse or neglect. I hope your community of colleagues can help with your decision.
Of course, you know all of this already. Just my 2 cents divided by a million or so...
