Last night, hapless Senator John McCain tweeted:
Last American combat troops leave Iraq. I think President George W. Bush deserves some credit for victory.
I commented on one of my favorite blogs Deus Ex Malcontent:
It’s like giving Billy credit for saving his town from the Gremlins.

My father has PKD and today he made his (I hope) first fistula and I saw in google images some pic showing the name and regions of the arm where the vain and artery are shown too. Can you please tell me how can I get this picture or how can I receive it? My doubt about the fistula surgery is how the blood continue to the end part of the arm, I mean, the fingers and the hand still receiving blood, how? I know that is the wrong place in your blog to put this comment, but I could not find another place to put it. Thank you for any hint here and/or by e-mail.
The arm has more than one artery and vein. While the fistula joins one artery and one vein to make one huge, fat vein for dialysis use, the other arteries and veins get the blood down to the finger tips and back.
