Metal Ion Toxicology and Allergy in Medical Implants and Occupational Exposure
This community investigates the biological effects of metal ions released from medical devices and occupational environments, focusing on allergic contact dermatitis, pulmonary fibrosis, and systemic toxicity.
The research centers on the release of nickel, cobalt, chromium, and beryllium ions from stainless steel, nickel-titanium, and cobalt-chromium alloys used in hip and knee arthroplasty, orthodontic archwires, and dental materials. Key methodologies include patch testing for allergic contact dermatitis, finite element analysis of ion release, and in vitro studies of oxidative stress and cell toxicity. A significant portion of the work examines interstitial lung disease and pulmonary fibrosis resulting from inhalation exposure to metal dusts and fumes, particularly in occupational settings. The community also addresses the diagnosis and management of metal hypersensitivity in patients with implanted prosthetics, distinguishing between local skin reactions and systemic immune responses.
Beryllium research accounts for 9.0% of all beryllium studies, representing 2,799 papers within this group. Nickel contributes 4,410 papers, comprising 2.2% of nickel research, while cobalt contributes 2,790 papers, or 1.9% of cobalt research.
The community comprises 19,373 papers, with the highest publication volume in Contact Dermatitis, Journal of Investigative Dermatology, and The Journal of Immunology.
Recent work includes updated guidelines for diagnostic patch testing, assessments of nickel and cobalt exposure in lithium-ion battery workers, and studies on the toxicological profile of cobalt-chromium dental alloys and nickel-titanium stents.
