Never Teach a Cardiologist How to Do Anything

Via a cardiologist friend (not quite seriously):
By the way, did I ever mention to never teach a single cardiologist how to perform any kind of dialysis? Because if just one of us knows, all of us will learn, and then we will start doing it.

Ask any radiologist about nuclear stress tests, MRI, CT, ultrasound or diagnostic catheterization.

Jennifer Strange Died from Water Intoxication (Hyponatremia) After Drinking Two Gallons of Water. How Low Did Her Serum Sodium Go?

More on the tragedy here. Some quick calculations. Assuming she weighed 63.5 kg (140 lbs), with a 50% body water percentage, her total body water was 31.75 L.

According to this article, she drank 2 gallons (7.5 liters) over approximately two hours, and we'll assume her kidneys eliminated 1000 ml of that -- figuring her max urine output was 500 ml per hour, and a full bladder holds at most about 1000 ml -- which means her total body water increased by about 6.5 liters in two hours (assuming that she absorbed all the water she ingested). If her serum sodium was initially normal at 140 mEq/L, after the contest she would have a serum sodium of [140 X (31.75 / 38.25)] = 116 mEq/L.

Serious symptoms usually occurs when the serum sodium is less than 120 mEq/L. Dropping your sodium from 140 to 116 could definitely lead to brain swelling and death.

Warren Ellis Reports for Reuters on Second Life

From Second Life Sketches: Two Worlds - Fame and Infamy:

It’s the biggest digital art installation in the world, the size of eight Manhattan Islands, but there are never more than 20,000 people there at the same time. It’s an instant messaging system, a software-coding environment, a design platform for 3-D architecture, an online community, and, conceivably, the germ of the next generation of computer operating systems. It’s called Second Life.
