Fools wrote an article in late 2002 titled Swinging for the Fences in Biotech in which PPHM was listed. I think that's the tie to how PPHM got used in this article which was originally written in June but just updated.
it's also funny that while the article kinda gave PPHM a somewhat negative twist, the volume went up a ton right when it was released... and gained a few cents too
