I missed a factor of 7. I guess I fail the fifth grade.:shakehead:

I get 1582, not counting a driver...but there must some trick to this somewhere

At depth, air viscosity increases as the inspired air increases in density. After a cursory web search, I found a very old article (Journal of Applied Physiology 9:5-10, 1956) which measured airway flow in people within decompression chambers. At air pressures simulating 99 feet depth, air...

A truly unruptured 2 mm aneurysm should not be a contraindication to diving. The risk of rupture of any asymptomatic aneurysm is low, and one this small is very low, so the likelihood of an event during the time underwater is miniscule statistically. Moreover, diving doesn't really change the...

Doc If you are saying this is likely BS, I agree

Very odd story. Spina bifida is a spectrum of diseases caused by improper formation of the neural tube during fetal development. We all start life as a flat embryo and then roll into a tube, from head to tail, as the fetus forms. If the tail end doesn't close completely, the lower spine shows...

There are a few reasonable quarries near Pittsburgh, specifically Strawberry and Crusty's, both in Slippery Rock. Crusty's is the private property of Scott's Scuba in Freeport, a very nice LDS. Crusty's is good because a) it isn't off-road, but has its own parking lot b) it has a dive shop/fill...

doc I guess what I meant to say was it is a difficult and exclusionary diagnosis given the information presented to us here. I agree that in many patients, the diagnosis is obvious and little time or money should be wasted searching out other causes. In others, it can be more problematic. But...

TMD is hard to diagnose; I would suspect you would have noticed pain in the joint when chewing, and that the relationship of pain to diving would be more immediate than you describe. It is still a likely cause, but I wouldn't take that as the correct diagnosis just yet. If you are over 50 or...

great news:D

Excuse me if I missed the point of this whole thread, or missed some posts (I tried to read them all), but, from what I have heard: 1) the doctors who attended her on the flight said the AED didn't trigger because she was in electromechanical dissociation, sinus rhythm with no pulse and then...

Not to second guess DAN, but there is no evidence to suggest that a person is any safer six months post bleed than three months, or twelve months post bleed than six months. They are just being extraordinarily conservative, which isn't necessarily a bad thing regarding a recreational activity...

It isn't a matter of being crazy, it's a matter of balancing the love of something versus its inherent risks, and living in a society where we allowed a certain freedom to do that. In some cases, we love something because it DOES have risk. Crazy is taking risks for no real return at all...

Are people being totally honest when they say they swim with feeding sharks to witness the beauty of these animals, which is indeed great but can be seen almost as closely at zoos and aquarium --- as opposed to looking for the bragging rights or thrill-seeking that comes with such activities? I...

I don't think an investigation into the alleged cheating is all that crazy, nor is a lawsuit by opposing players to be considered lunacy. Football is a 20 billion dollar a year industry, with another 20 or more billion in wagering on it. As such, it is not above charges of industrial espionage...

A great fourth quarter of football. Condolences to Pats fans who still had a great, if not perfect, season. Too bad their coach couldn't wait until the game was over to leave. Perhaps he has some more illegal film footage to review for next year...

If you have to pay for it on your own, check out the cost of a CT scan with IAC (internal auditory canal) views...it might be as good for acoustics as MRI and cheaper (and faster too). I can't guarantee it will be chepaer, since I haven't personally checked the costs recently, but CT is usually...

One of the issues here is whether this aneurysm actually ruptured. A small leak may be missed on CT scan, even on MRI. Blood in the spinal fluid may be due to a "traumatic tap", i.e., bleeding from the needle itself. Usually, the fluid is centrifuged to get the red cells out and the fluid...

It's over. No survivng team can match the Pats. Unless Brady goes down, give them the rings now and let's us just watch the commercials on Super Sunday, sans the meaningless game.

I was privileged to meet him about six or seven years ago. He was on a fund raising trip to the US for a hospital in Nepal. He gave a speech to a large gathering and then, for those of us making a sufficient donation, he attended a smaller party. My sister and I got him to autograph our copy of...
