Transparency to Reduce Surgical Implant Waste.

Background: Rising health care costs and emphasis on value have placed the onus of reducing healthcare costs on the surgeon.

Methods: Financial data from 3,973 hip, knee, and shoulder arthroplasties performed at a physician owned orthopedic hospital was retrospectively reviewed over a two-year period. A wasted implant financial report was posted starting the second year of the study.

Lumbar artificial disc replacement in Ehlers-Danlos syndrome: A case report and discussion of clinical management.

Background: Ehlers-Danlos syndrome (EDS) is a heterogeneous collection of connective tissue disorders characterized by varying degrees of skin hyperextensibility, joint hypermobility, and tissue fragility. Surgical treatment of EDS patients is complicated by the extreme fragility of their vessels and tissues. The purpose of this case report is to present the management of an EDS patient with debilitating low-back pain.

Non-infectious aggregates of the prion protein react with several PrPSc-directed antibodies.

The key event in the pathogenesis of prion diseases is the conformational conversion of the normal prion protein (PrP) (PrP(C)) into an infectious, aggregated isoform (PrP(Sc)) that has a high content of beta-sheet. Historically, a great deal of effort has been devoted to developing antibodies that specifically recognize PrP(Sc) but not PrP(C), as such antibodies would have enormous diagnostic and experimental value. A mouse monoclonal IgM antibody (designated 15B3) and three PrP motif-grafted monoclonal antibodies (referred to as IgG 19-33, 89-112, and 136-158) have been previously reported to react specifically with infectious PrP(Sc) but not PrP(C).
