With a raging fever, vomiting and diarrhea, Gregory Rodriguez thought he had some kind of bug when he checked himself into the emergency room at a New York hospital in September. Two days later, he was unconscious, hooked up to an artificial lung and a candidate for a double lung transplant.

Cartridges contained polyethaline glycol when they first were introduced to the market. (at least that's what I was told at the time)

That's a wood preservative. Fills pores in wood with a water resistant material to prevent it from degrading. Also a primary ingredient in anti-freeze.

Seems strangely consistent with the symptoms which are presenting.

How did any of this make it to market in the first place?
