Eosinophilia in hemodialysis patients.

abstract：:Thyrotoxic crisis (thyroid storm) is a life-threatening condition. Standard therapy is based on thiamazole, prednisolone, and nonselective beta-blockers. Extracorporeal plasmapheresis is an additional tool for removing circulating thyroxine in patients who do not respond quickly to conventional standard therapy. As th...
