Jennifer Cahill, Ryan Toholka, and Rosemary Nixon report their clinic’s methylisothiazolinone patch-test rates and list disposable wipes among exposures. The DOI printed on the letter is 10.5694/mja13.10946. A different Cahill paper in Pediatrics is not this document.
Key numbers
Relevant methylisothiazolinone reactions were 3.5% (15/428) in 2011, 8.4% (38/454) in 2012, and 11.3% (40/353) to November 2013. These are preservative allergy rates, not metal concentrations.
Methods (brief)
Baseline patch-test series in one Australian clinic.
Evidence fitness
The rates describe preservative allergy. They do not describe metals in wipes.
Limitations
One-page letter. Denominators are patch-test patients, not wipe products assayed for metals.
