One study (McFarland, et al. 1984) saw no difference in A1C results among 41 women with normal OGTTs and 12 womenwith OGTTs positive for gestational diabetes. Other studies had simular results. ....Frye goes on to postulate that this proves that gestational diabetes does not exist as currently defined. If anyone wants (tragi-)comic relief from real science I suggest Anne Frye's book. [no ISBN, published in 1993 by Laybrys press availible from the author and most of the midwifery supply houses in the USA...press address 7528 NE Oregon St., Portland, Or 97213 phone (503) 255-3378] Somebody stop this woman before she publishes again!

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.
