    Allergic contact dermatitis is common in children, with mercury and nickel sulfate being the most frequent triggers. Even infants can develop reactions to metals found in everyday items like earrings.

    Area of Science:

    • Pediatric Dermatology
    • Allergology
    • Toxicology

    Context:

    • Contact dermatitis is a prevalent skin condition in children.
    • Identifying specific allergens is crucial for effective management.
    • Pediatric populations may exhibit unique sensitivities to common metals.

    Purpose:

    • To investigate the prevalence and patterns of allergic contact dermatitis in children.
    • To identify the most common metallic allergens responsible for positive patch test reactions in pediatric patients.
    • To assess the age distribution of allergic responses to specific metals.

    Summary:

    • Patch tests were conducted on 100 children using Nickel sulfate, cobalt chloride, bichromate, and mercury.
    • Twenty children showed positive allergic reactions, with 11 to mercury and 9 to nickel sulfate.

  • The youngest patient, an 8-month-old girl, reacted to nickel sulfate from earrings worn since the first week of life. Mercury emerged as the strongest sensitizer in infancy, and peak incidence occurred in children aged 6-8 years.

    • Impact:

    • Highlights mercury and nickel sulfate as significant allergens in pediatric contact dermatitis.
    • Underscores the importance of considering even early-life exposures to metals.
    • Provides data on age-related prevalence, aiding in targeted prevention and diagnosis strategies.
