The Bellevue Literary Review (BLR):
BLR is published by the Department of Medicine at New York University. We invite submissions of previously unpublished works of fiction, nonfiction, and poetry that touch upon relationships to the human body, illness, health and healing. We encourage creative interpretation of these themes.
There is a link above to the Spring 2006 edition with some of the writing available for free on the website, and some submission guidelines. There are some very talented medical writers out here in the blogosphere.
Just a thought.
