Sensitization to Implant Components Is Associated with Joint Replacement Failure: Identification and Revision to Nonallergenic Hardware Improves Outcomes.

Background: Over 90% of one million annual US joint replacements are highly successful. Nonetheless, 10% do poorly owing to infection or mechanical issues. Many implant components are sensitizers, and sensitization could also contribute to implant failure.

Developing effective worker health and safety training materials: hazard awareness, identification, recognition, and control for the salon industry.

Objective: In addition to formaldehyde, workers in salons can be exposed to other chemical irritants, sensitizers, carcinogens, reproductive hazards, infectious agents, ergonomic, and other physical hazards. Worker health and safety training is challenging because of current product labeling practices and the myriad of hazards portending risk for a wide variety of health effects.
