How about you Mats? >Jay Naliboff, MD >Farmington, Maine > The frozen north eh (please note the last "word" which truely identifies where I am from). Having practiced medicine in Montreal, Calgary, and Chilliwack (close to Vancouver), I can confidently say I know about medicine in the colder climbs. Although we see a lot of peop;e diagnosing seasonal affective disorder (SAD), I have not noticed a lot of seasonal amenorrhea. I have however seen young women that go back to school in the fall and become amenorrheic (sp?) at about the time of their first midterm. J.G.M.

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.
