Dr. Frankenstein Lives. Sort of.

Dr. Sergio Canavero wants to be the modern-day Victor Frankenstein. Create a human from parts. Two parts anyway. A head and a body. Yes, he wants to do a head transplant. His proof that it works? Stimulating the nerves of the spinal cord to test his efforts.

Remember high school biology? That poor frog with his head cut off? Yet applying a current to its spinal cord made the legs jump. It’s what nerves and muscles do when stimulated. It’s not life; it’s a parlor trick—-for lack of a better word.

So, could Dr. Canavero’s experiment work? This head transplant? Maybe, anything is possible. But smart money is on not a chance.

What of the original Frankenstein? Art and life often intertwine and had it not been for a volcanic eruption on the other side of the world Marry Shelly’s classic might never have been written.

Maybe Columbus Wasn’t “The Father of Syphilis” After All

 

Columbus

 

It has long been believed that the sailors who crewed Christopher Columbus’s ships in his famous 1492 voyage contracted syphilis from the natives and transported the deadly disease back to Europe. But was this disease already in Europe long before Columbus was even born? According to a recent article in the Journal of Biological and Clinical Anthropology that just might be the case.

Of course, now most cases of syphilis are treatable and curable with antibiotics, but in 1492 things were a bit different They didn’t know what caused it and indeed that bacteria even existed. Antibiotics? Still centuries away. So syphilis was often deadly, and, if not, it was very disfiguring and incapacitating.

The real culprit is a spirochete called Treponema palladium. And it might have been in Europe as early as 1320.

The Plague—Yes That Plague—Is Alive and Well

Black Death

The Black Death. It hit Europe in the mid 1300s and killed millions—-some say 100 million or between 1/3 and 1/2 of Europe’s population. It changed history. It altered mankind’s view of religion. It disrupted travel and trade. It helped bring on the so-called Dark Ages.

In truth there were several plagues. caused by several different diseases, but the Black Death was especially destructive. Though it has been challenged by some, the Black Death was in all likelihood caused by a nasty little critter called Yersinia Pestis.

But that was centuries ago. Now we know what causes plague and we know how to treat it. It’s passed to humans by bites from infected fleas and can be eradicated with antibiotics. At least in most cases. So like small pox, isn’t it a relic of the past? Not really. The bug is out there and every now and then it raises its head as if to say—-Remember me?

Several cases have cropped in Colorado in the past couple of years, with two recent deaths: high school athlete Taylor Gaes and an as yet unnamed adult. Last year there were other cases of this infection.

And now another case has occurred in California–a child camping in Yosemite National Park.

So the plague is not just of historical significance, but rather is still with us.

I’ve blogged about this before and here are the links to those posts:

Q and A: What Happens When a Person Is Exposed to the Vacuum of Space?

Astronaut

Q: What sort of damage does the human body suffer in the vacuum of space?  How long can one survive and what will happen to the person who does survive?  My scenario involves an astronaut whose faceplate blows out, but not before he depressurizes his suit sufficiently to prevent immediate death.

A: First of all the victim would not explode as was the case in the movies such as Total Recall. But some very bad things do happen internally and they happen very quickly. Whether he depressurizes somewhat beforehand or not, his survival once he reached zero pressure (vacuum) would likely be measured in seconds.

Space decompression sickness is similar to that of a scuba diver that rises too rapidly after a prolonged exposure to the pressures of the deep. In this case the diver is going from excess pressure to normal pressure. In space the victim goes from normal pressure to zero pressure. Same thing physiologically.

In diving, the problem is that the excess pressure causes excess nitrogen (N) to dissolve in the blood. This N will come back out of the blood as the pressure is reduced. This should happen slowly to prevent decompression sickness or the bends. But, if the diver rises rapidly, the pressure drops rapidly, and the N comes out of the blood quickly, forming N bubbles in the blood stream. This is similar to popping the top on a soft drink. Here the release of the pressure allows the carbon dioxide (CO2), which was placed into the liquid under pressure, to come out of the liquid and form bubbles. We call this carbonization. A good thing for your soft drink, but not so good for your brain and heart and muscles.

In space decompression basically the same thing happens. Apparently the culprit is water and not N in this situation, however. With the sudden release of pressure, the water in the blood “boils,” becoming a gas, and bubbles form in the system. I should point out that in chemical and physical terms boiling simply means the changing of a liquid to a gas. This can be accomplished by adding heat (boiling water on a stove) or by lowering the ambient pressure (popping open a soft drink). In the case of space decompression it isn’t that the blood gets hot, but rather that the pressure that keeps the water in its liquid state is removed and the water changes to its gaseous state, or boils. Doesn’t sound very pleasant does it?

Though studies on the effects of exposure to a vacuum have been done on chimpanzees, there are no real data on what happens to humans exposed to zero pressure except for a couple of incidents where an astronaut or a pilot was accidentally exposed. Of course, rapid decompression has caused deaths in both high-altitude flights and in June, 1971 when the Russian spacecraft Soyuz 11 suddenly lost pressure, killing the 3 cosmonauts on board, but survivors are few and far between.

On August 16, 1960, parachutist Joe Kittinger ascended to an altitude of 102,800 feet (19.5 miles) in an open gondola in order to set a world record for high-altitude parachute jumping. He lost pressurization in his right glove but proceeded with his ascent and jump. He experienced pain and loss of function in his hand at high altitude but all returned to normal once he descended via chute to lower altitudes.

In 1965 at NASA’s Manned Spacecraft Center near Houston, TX, a trainee suffered a sudden leak in his spacesuit while in a vacuum chamber. He lost consciousness in 14 seconds, but revived after a few seconds as the chamber was immediately re-pressurized. He suffered no ill effects—due to his very brief exposure—but stated that he could feel water boiling on his tongue. This was actually the above mentioned boiling scenario in which water (in this case saliva) becomes a gas on exposure to zero pressure.

A case of partial, prolonged exposure occurred during an EVA (space walk) in April 1991 on the US space shuttle mission STS-37. One astronaut suffered a 1/8 inch puncture in one glove between the thumb and forefinger. He was unaware of it until later when he noticed a painful red mark on his skin in the exposed area. It appeared that the area bled some but that his blood had clotted and sealed the injury.

So, what happens to a human exposed to zero pressure? Since there is no oxygen in such an environment, loss of consciousness occurs in a matter of seconds. Also, if the victim held his breath (don’t do this during scuba diving when coming up from depths either), the air in his lungs would rapidly expand and his lungs could be damaged, bleed, or rupture. Better to open his mouth and exhale the rapidly expanding gas from his lungs.

Water in his blood stream would immediately begin to “boil,” filling the blood stream with water vapor (the gas form of water) and stopping his heart. Bubbles might appear in the blood stream and cause damage to the body’s organs, particularly the brain. As a result, the brain and nerves cease to function. As more and more gas formed within the body, the entire body would swell but it would not explode.

Exposure to heat or cold or radiation might also occur but it will do little harm since the victim would already be dead.

But what if the exposure were brief and the person rescued? Treatment would be to immediately return him to a pressurized environment and give him 100% oxygen. He may survive unharmed or may have brain and nerve damage which could be permanent.

For your scenario, whether he partially decompressed or not, he would be in trouble very quickly. When your victim’s faceplate ruptured he would hopefully begin to exhale air to prevent the expanding gases in his lungs from rupturing them. As air, and thus oxygen, flowed from his lungs and into space, the oxygen content of his blood would rapidly drop and he would lose consciousness in 10 to 20 seconds. He would then die in short order. If he were quickly rescued, he would be returned to the spacecraft, which would be pressurized, and would be given 100% oxygen via a face mask. He could survive intact or with brain damage. It’s your call. Either way works.

 

Would Lincoln Have Survived With Modern Medical Treatment?

Lincoln 1863

Lincoln’s assassination took place 150 years ago this evening. He died the next day, April 15, 1865. Since he lived overnight, could modern medicine techniques have saved him? Here is a question that appeared in my second Q&A book—FORENSICS AND FICTION

Would Abraham Lincoln Have Survived His Injuries Today?

Q: This is a pure curiosity question. Do you think that Lincoln could have been saved if they had today’s medical knowledge, techniques and equipment in 1864?

Martha Kuhn, Mt. Gilead, Ohio

A: Most likely, yes. He was shot in the back of his head, and the bullet apparently entered his brain. He lived for many hours so the shot was not immediately fatal. A surgeon probed the wound but feared removing the bullet, since it might cause bleeding. He probably should have, but we’ll never know.

Similar wounds today are treated by a trip to the OR, removal of the bullet, controlling bleeding, and preventing any subsequent infection. He would have had at least a 50 percent chance of survival. And since he survived several hours anyway his survival with modern techniques would likely have been much higher.

Heartbeats and Art

First a little semantics: Arrhythmia actually means “without rhythm.” So the only true arrhythmia is asystole or cardiac standstill, which means the heart has no rhythm and simply sits there quietly. Not a good thing. Not compatible with life.

The proper term is dysrhythmia, which means an “abnormal rhythm.” There are many different types of these.

Some are slow:

Sinus Brady

Others are fast:

SVT

We all have dysrhythmias but most of us are totally unaware they are happening. Other folks experience palpitations—-an awareness of a cardiac irregularity. These can sometimes be alarming and I regularly see patients in my office with this complaint.

Beethoven

But can your heart’s rhythm effect your creativity? Did a dysrhythmia contribute to Beethoven’s musical prowess? Did Shakespeare’s heart beat in iambic pentameter?

As a cardiologist, I’m not sure I buy into this but it is intriguing:

Medicine has a lot of very strange disorders in its catalog of maladies.

Fibrodysplasia Ossificans Progressiva (FOP or Stone Man Syndrome) is one of them.
