English-Spanish Medical Corpora

Dear all,

I am student of Msc Language Technology in Saarland University. I 
am looking for a English-Spanish medical corpora or, failing that, 
papers, articles, any kind of publication... where you can find 
English-Spanish medical texts aligned (like, for example, 
abstracts in both languages). I hope someone can help me. Thank 
you in advance,

Mario
