Heart Transplant Waiting List Implications of Increased Ventricular Assist Device Use as a Bridge Strategy: A National Analysis.

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...

abstract：:Aseptic loosening is the major cause of failure of hip implants after total hip arthroplasty. Stress shielding of the femur is known to be the principal factor involved in the aseptic loosening of hip implants. Solid stems are found to have a greater rigidity; therefore, they transfer less load proximally, which resul...
