Nickel Allergy and Our Children's Health: A Review of Indexed Cases and a View of Future Prevention

Area of Science:

• Pediatric Dermatology
• Environmental Health
• Allergy Immunology

Background:

• Nickel is a primary cause of allergic contact dermatitis (ACD) in children and adolescents.
• Exposure to nickel, often through piercings and consumer products, triggers ACD in susceptible individuals.
• Nickel ACD results in significant pediatric skin disease across the United States.

Purpose of the Study:

• To review the significant role of nickel in pediatric skin disease within the US.
• To highlight the need for public awareness campaigns among caretakers to decrease nickel-related morbidity.
• To advocate for the adoption of European legislative models for nickel exposure prevention.

Main Methods:

• Review of peer-reviewed literature on nickel ACD in children.
• Analysis of common sources of nickel exposure in pediatric populations.
• Comparison of regulatory approaches to nickel exposure in the US versus Europe.

Main Results:

• Nickel ACD is prevalent in children, with cases reported in 28 US states.
• Numerous everyday items, including jewelry, coins, and electronics accessories, contain nickel.
• Patch testing is a standard diagnostic method for nickel ACD in children over six months.

Conclusions:

• The US lacks mandatory nickel exposure restrictions, unlike European countries.
• Denmark's regulations demonstrate that controlling nickel content reduces ACD and healthcare costs.
• Implementing preventative strategies and potentially legislation can mitigate nickel-induced skin problems in children.
