Re: USG in diagnosing calcification From: Terry J DuBose (tjdubose@juno.com) Sun Jun 8 17:36:00 2003 Messages sorted by: [ date ][ thread ][ subject ][ author ] Next message: Philippe Coquel: "Re: tranvaginally ortransabdominallly" Previous message: Lungsi: "USG in diagnosing calcification" Maybe in reply to: Lungsi: "USG in diagnosing calcification" In the 1980's there was some hope that placental grading would help in determining fetal maturity in the way that the LS Ratio does. However, it did not turn out to be helpful. It appears that only the extreme cases of grades are significant. Diabetic mothers tend to have "immature" placentas of grades "0" later in pregnancy, and IUGR and mothers that smoke tend to have premature placentas of grade "III". Basically, a grade "0" (smooth homogenous texture) should not be found after about 27 weeks, and mature grade "III" (inhomogeneous, calcifications around cotyledons extending to the base plate & central venous lakes" should not be found before 27 weeks. See DuBose; FETAL SONOGRAPHY, Saunders 1996, p. 354-358. Otherwise there does not seem to be any significance to placental grading.

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.
