Complete clinical course of envenomation by Protobothrops mangshanensis: delayed coagulopathy and response to Trimeresurus albolabris antivenom.

Introduction: Protobothrops mangshanensis, the Mangshan pit viper, is a rare pit viper native to the area surrounding Mount Mang in China's Hunan province. Toxicity from envenomation is not well characterized.

Case Details: A 33-year-old male presented to an emergency department (ED) after being bitten on the forearm by his P.

Bone ingrowth in the presence of particulate polyethylene. Synergy between interface motion and particulate polyethylene in periprosthetic tissue response.

We have investigated whether the presence of polyethylene (PE) alone is sufficient to cause an aggressive periprosthetic tissue response, or whether certain mechanical interface conditions can allow bone to grow while in the presence of PE. An experimental implant was loaded in the presence and absence of particulate PE under stable and unstable conditions. Bone with a thin, discontinuous fibrous membrane formed in both groups of stable implants, either in the presence or absence of PE.

A controlled experimental model of revision implants: Part I. Development.

We investigated the roles of particulate matter with unstable implant, in engendering the aggressive tissue response associated with implant loosening in humans. This study serves as a basis for establishing a controlled animal model to reproduce the conditions present after implant loosening. The model includes a 6 mm polymethylmethacrylate (PMMA) cylinder concentrically pistoning 500 microm under load in a 0.
