Researchers at Johns Hopkins published a study that reports that MRI scans CAN cause feelings of dizziness induced by magnetic fields causing motion of the electrically charged fluid of the inner ear.
In both ears, there is a “gyroscope” called the labyrinth. Whenever the head turns or a force like gravity is exerted on this system, fluid moves within, which tells the brain that motion has occurred. It’s much like looking into a glass of water and based on the way the water tilts in the glass, you can guess which way motion is occurring.
In any case, the study Read more »

On Sept 16, 2011, the Stone Temple Pilots had to cancel their tour because their lead singer Scott Weiland was placed on voice rest due to damaged vocal cords at risk for permanent damage. Specifically, the doctors at University of Cincinnati Voice Health Center determined that he had scarring on his left vocal cord and a tremendously inflamed right vocal cord.
The left vocal cord scarring is likely from past vocal trauma that did not heal properly and is now permanently damaged whereas the right vocal cord is at risk of also becoming permanently damaged if not aggressively managed. The picture shown here is an example with inflammation involving both vocal cords. Compare this with Read more »

MSNBC reported recently that a shot of carbon dioxide gas into the nose can help with allergies based on preliminary findings funded by Capnia, a company that makes the product.
Upside:
Symptoms of nasal allergies improved within 30 minutes.
No liquid is involved… just carbon dioxide gas.
Downside: Read more »

Surgery is messy… and I don’t mean in terms of blood and guts…
What I mean are wires, cables, tubing, etc.
Electric cord for the operating tableLet’s take a routine tonsillectomy and adenoidectomy for example…
- Electric cord for the anesthesia machine
- Electric cord for the surgeon’s headlight
- Light cord from the surgeon’s headlight to the lightbox
- Breathing circuit tube from the patient to the anesthesia machine
- Carbon dioxide outflow tube from the patient to the anesthesia machine
- Suction tubing from the surgical table to the vacuum canister
- Vacuum cable from the vacuum canister to the wall socket
- Electrocautery cable (along with electric cord to power the machine)
- Coblation cable (along with electric cord to power the machine)
- IV fluids lines from patient to IV bags
- EKG lines
- Grounding pad cable
- All the wires and cables that go with running a computer
- etc. etc. etc. Read more »

So how would one go about figuring out the best medication for dizziness due to motion-sickness leading to nausea and even vomiting?
Well, step 1… Put a bunch of people in a machine and figure out the necessary motions that will cause dizziness.
Step 2… Do the same thing, but this time, put people on different medications and figure out what works the best.
Sound crazy?
Well it has been done by the friendly folks at NASA. Read more »
