Background And Objective: Diagnosis of vibratory urticaria/angioedema is established after performing the vortex provocation test. There is current consensus on measuring the forearm perimeter after running such test to define a positive response to it.
Material And Method: We evaluated the frequency of prior symptoms following vibratory stimuli in volunteers using a questionnaire, response to the vortex provocation test in the same volunteers (increase in forearm perimeter, erythema, localized edema, heat, and pruritus), interrater reliability, and correlation between the scores obtained in the questionnaire and response to the test.
Article Synopsis
- Patch test outcomes can be affected by age, but there are mixed findings on how age impacts these results.
- The study involved over 13,000 patients and revealed that middle-aged adults (31-65 years) had the highest rates of positive skin sensitisation results, particularly for certain substances like nickel and potassium dichromate.
- Overall, while age does influence some patch test results, most allergens showed consistent reactivity across ages, underscoring the importance of standard testing regardless of age.
Background: Reports of allergic contact dermatitis (ACD) to phytonadione epoxide (PE) in cosmetics suggest that PE is as powerful a sensitiser as its parent compound phytonadione.
Objective: To evaluate a case series of ACD to PE in Spain.
Methods: We reviewed the records of 20 patients with ACD to cosmetics containing PE diagnosed across Spain between January 2019 and June 2023.
