You might also contact Niavikar Dahiya MD nirvi@satyam.net.in He is an online acquaintance of mine and I believe he has done some work on this subject. He is in Coimbature, Tamil Nadu, India. If that email address does not work try nirvi@vsnl.com.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
