Contact dermatitis to PPD rubber in Maleki shoes
Contact Dermatitis
|April 1, 1977
Summary
A case study links traditional Persian Maleki shoes, now often using recycled car tires, to rubber dermatitis. Patch testing identified PPD rubber as the likely allergen, highlighting a potential health risk from footwear materials.
Area of Science:
- Dermatology
- Materials Science
- Public Health
Background:
- The traditional Persian Maleki shoe, with over 800 years of history, features a cloth sole and cotton upper.
- Recent use of recycled car tires for shoe soles in Iran presents new material considerations.
Observation:
- A patient presented with characteristic rubber dermatitis on the soles of his feet.
- The patient had a history of wearing Maleki shoes for several years.
Findings:
- Patch testing revealed a 2+ positive reaction to PPD rubber.
- The positive reaction suggests PPD rubber in the Maleki shoes as the cause of the dermatitis.
Implications:
- This case highlights a potential allergic contact dermatitis risk associated with recycled tire materials in footwear.
- Further investigation into footwear material safety and allergenicity is warranted.
- Public health awareness regarding potential allergens in commonly worn items is important.
