I am a doctor and specialize in Obstetrics and Gynecology. In Spain, obstetric and gynecologic ultrasound is usually performed by Ob/Gyns, not by radiologists, so sometimes I have difficulty solving the case of the week when no ultrasound images appear (conventional radiology, CT, MR, etc). I work at a university hospital in the morning and I do prenatal diagnostic ultrasound in the afternoons in a private clinic. I live in Valladolid, a city of 350,000 inhabitants, capital of Castile and Leon in Spain. I am married to an ophthalmologist and have two children; the older daughter is now at West Virginia University (after completing her two degrees) and the younger son is studying engineering in my hometown, Valladolid.As for my hobbies, the little free time I have available, I spend with my family. I like to listen to classical music (my favorites are all Baroque music, especially Bach, Mozart and Verdi) and work on the computer. I believe the there are many learning opportunities offered by the websites. I take many specialty courses through the internet and I am hooked to TheFetus.net (it"s my homepage on all my computers and I look at it as a source of clinical information to improve my clinical practice). Earlier this year I decided to guess the "Case of the week†to see how many got it right. I have not done bad at all. I consider it a sensational and entertaining way to learn, but I admit that I feel some anxiety when I am unable to answer. My main problem is English, but I know that Philippe is lenient with grammatical errors and all sorts.On vacation, I try to travel with my family. I love to get to know, as deeply as possible, various wonderful cities. My last trip was to Berlin, in early November, and the photos that I send are made there. Congratulations Javier!!
