Principles of method if other than guideline:
Human patch test
Patch tests were exposed for 48 hours using Finn Chambers (inner diameter 8 mm) on Scanpor tape (Smart-Practice, Greven, Germany). Reading of results was performed on day (D) 2 and D3 according to the current guidelines of the German Contact Dermatitis Research Group. Patients with positive results underwent an additional D7 reading. As a standard operating procedure in the clinic for patch tests, patients were reminded to revisit the clinic in case of any novel reaction on D7. In case of uncertainty, patients were asked to send in a photo in advance, if they refrained from taking the trip to our hospital. However, no such revisit was necessary on or around D7 in the study cohort.

Results and discussion

Applicant's summary and conclusion

Executive summary:

Among 145 patients patch tested with i.a. propan-1-ol, only one nurse was detected with a possible allergy to 1-propanol. The clinical relevance of the positive patch test result was controlled by repetitive open application tests (ROATs), which were performed two times daily over 7 days. Although the first ROAT was positive, a second one was not able to confirm the finding.
