Metal Allergy

Novel metal allergy patch test using metal nanoballs

BACKGROUND Patch tests are often used in the clinical diagnosis of metal allergies. In currently available patch tests, high concentrations of metal salt solutions are used. However, diagnosis accuracy can be influenced not only by acute skin reactions to high concentrations of metal salt, but also by skin reactions to other components present in the patch or to pH changes. In this study, we de...

Metal sensitivities and orthopaedic implants revisited: the potential for metal allergy with the new metal-on-metal joint prostheses.

The potential of metal-containing orthopaedic prostheses to induce problems through metal allergy taxes dermatologists and orthopaedic surgeons alike. Metal-on-plastic joint replacements are not thought to induce metal allergy but wear products, principally polypropylene particles, produce a foreign body reaction in bone and may lead to aseptic loosening of the joint. Orthopaedic surgeons are i...

Inflammation: Biologic effect of implant debris Hypersensitivity: Metal-induced allergy

Metal Allergy and Systemic Contact Dermatitis: An Overview

Contact dermatitis is produced by external skin exposure to an allergen, but sometimes a systemically administered allergen may reach the skin and remain concentrated there with the aid of the circulatory system, leading to the production of systemic contact dermatitis (SCD). Metals such as nickel, cobalt, chromium, and zinc are ubiquitous in our environment. Metal allergy may result in allergi...

The association between metal allergy, total knee arthroplasty, and revision

BACKGROUND AND PURPOSE It has been speculated that the prevalence of metal allergy may be higher in patients with implant failure. We compared the prevalence and cause of revisions following total hip arthroplasty (THA) in dermatitis patients suspected to have contact allergy and in patients in general with THA. Furthermore, we compared the prevalence of metal allergy in dermatitis patients wit...
