Correlations of patch test reactivity and the repeated open application test (ROAT)/provocative use test (PUT).
    Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 2004, Volume: 42, Issue:11

    The clinical relevance of patch test reactions is often difficult to determine. Use tests have been developed to further evaluate the significance of patch test results. We review studies that have defined correlations between the threshold concentrations at patch testing and the outcome of use tests for particular chemical allergens. Results of patch testing with serial dilutions of colophony, cinnamic aldehyde, and isoeugenol have shown concordance with the outcome of use tests. On the other hand, poor correlations between patch test reactivity and the use test were demonstrated in another study on isoeugenol and on studies on hydroxycitronellal, formaldehyde and chromium. These studies shed light on some factors that may influence the outcome of use tests. Individual factors such as patch test sensitivity, regional variations in reactivity and percutaneous penetration appear to play significant roles. Exposure dose, length of time of exposure, and other factors yet to be determined also affect degree of reactivity. Because patients with low thresholds in serial dilution patch testing are known to react to lower concentrations of products at use testing, results of these studies may be used to help identify subjects with a high risk of developing clinical disease. From the public health standpoint, data obtained may be used as a guide in limiting exposure concentrations in consumer products.

Skin symptoms among workers in a spice factory.
    Contact dermatitis, 1993, Volume: 29, Issue:4

    Workers in a Swedish spice factory (n = 70), and in the office (n = 23) of the same company, were investigated by questionnaire regarding skin symptoms. In a 2nd part of the study, subjects reporting skin symptoms were examined and investigated by patch and prick testing. Skin symptoms were reported by 1/2 the factory workers. Pruritus and skin irritation, particularly from cinnamon powder, were common. Patch test reactions to cinnamic aldehyde were found in 11/25 factory workers, but in several cases, the nature of the reactions was difficult to evaluate. Irritant patch test reactions were seen from powders of cardamom, paprika and white pepper. On prick testing, 6/25 workers reacted to cinnamic aldehyde. The results illustrate the difficulties of patch testing with spices and indicate the need for further research and validation of methods.
