Two-year follow-up of the SMR stemless platform shoulder system: a multicenter, prospective clinical study.

Background: The use of stemless shoulder arthroplasty for osteoarthritis has grown substantially over the past decades. The goal of this study is to evaluate the clinical and radiological outcomes of the Lima SMR stemless anatomic and reverse total shoulder arthroplasty.

Methods: Seventy-three implants in 73 patients (61 anatomic total shoulder arthroplasties [aTSAs] and 12 reverse shoulder arthroplasties [RSAs]) were analyzed with a minimum follow-up of 2 years.

No clinical difference between TiN-coated versus uncoated cementless CoCrMo mobile-bearing total knee arthroplasty; 10-year follow-up of a randomized controlled trial.

Purpose: Improvement of biomechanical properties of cobalt-chromium-molybdenum (CoCrMo) implant surface and reduction of adhesive wear is achieved by titanium-nitride (TiN) coating in vitro. Less pain, higher postoperative outcome scores and a lower revision rate after TKA with a TiN-coated CoCrMo TKA compared with uncoated CoCrMo TKA after 10-year follow-up was hypothesized.

Methods: In a double-blinded RCT, 101 patients received a cementless mobile-bearing CoCrMo TKA, either TiN-coated or uncoated.

[Immunohistology of bullous autoimmune skin diseases].

Autoimmune bullous dermatoses undertake frequently oropharyngeal mucous membranes and the skin surface, either in succession or simultaneously. Actual observation technics by photon and electron microscopy, by immunofluorescence and immunohistochemistry (with specific antibodies) have allowed to differentiate more particularly pemphigus, bullous pemphigoid, cicatricial pemphigoid, acquired bullous epidermolysis, all autoimmune bullous affections.
