Chronic eosinophilic leukemia (CEL) is a chronic myeloproliferative disorder of unknown etiology in which a clonal proliferation of eosinophilic precursors results in persistently increased numbers of eosinophils in the blood, bone marrow, and peripheral tissues. In CEL, the eosinophil count is greater than or equal to 1.5 × 109 /L in the blood. To make a diagnosis of CEL, there should be evidence for clonality of the eosinophils or an increase in blasts in the blood or...
According to the findings of a 2006 Environmental Protection Agency
scientific advisory panel, the primary chemical used to make Teflon --
perfluorooctanoic acid or PFOA -- is a "likely human carcinogen." But that
applies only to PFOA that has been emitted into the environment.
"The link between Teflon cookware and cancer is an entirely different
subject," says Robert Wolke, professor emeritus of chemistry at the University
of Pittsburgh and author of the two-part book series What Einstein Told His
Cook. "There is no PFOA in the final Teflon product, so there is no risk
that it will cause cancer in those who use Teflon cookware."
That said, Wolke warns, "heating a Teflon pan to 500 degrees or more" (as
happens when we leave empty pans on high heat by mistake) can result in smoke
and gases that can cause flu-like symptoms in humans and kill pet birds.
So keep an eye on your stovetop and keep your smoke alarms in good working
