Nanette Silverberg and colleagues describe 30 pediatric patients with nickel contact hypersensitivity. The DOI is the record that matches this title.
Key numbers
All 30 children had a positive patch test to nickel sulfate 5%. Half (50%) had an id reaction. The abstract’s 14.3% North American incidence, and the 10% figure from ten years earlier, are background statements, not rates from these 30 children, and they are not entered as this study’s results.
Methods (brief)
Clinical series. Patch testing with nickel sulfate 5%.
Evidence fitness
The 30 and the 50% describe this series. They do not describe nickel in a food or a consumer product.
Limitations
Selected clinic patients. No product concentrations.
