Dr. Turecki is a psychiatrist and he has written an interesting article - The Behavioral Complaint. In this article he has used the word "etiology".
Here in looney, homophobic, racist Washington County, Oregon we have a psychiatrist who used to be a cop (maybe he still is a cop). His name is Dr. Ron Turco. When he's not diagnosing people, including me, as members of the international homosexual, Satanic ritual gang he's pumping out accolades he's awarded himself. Interestingly, since my sister, Chris Andrea Hays, became a member of a crazy, homophobic, white supremacist gang she has become convinced she's a victim of the international, homosexual Satanic ritual abuse conspiracy. Of course, she's also become convinced she was abducted by space aliens so we know her enchilada is a few ingredients short.
