Contact dermatitis (CD) is a common inflammatory skin disease, affecting approximately 15-20% of the general population in industrialized countries and ranking first among occupational diseases in many European countries.
The patch test method aims at reproducing the eczematous lesions by applying occlusive patches containing the suspected allergens to the patient's healthy skin. It requires experienced medical staff to read the reaction.
Newtones Technologies society has developed a new tool, the SkinCam®, able to capture high resolution cross and parallel images, allowing a quantification of color and relief of skin.
This study aims to illustrate patch test results, describing skin appearance (color, roughness, shine), using photographs taken by the SkinCam®.
Patient, male or female, over 18 years of age
Patients called for reading patch test, applied 72 or 96 hours ago
Patients agreeing to have unidentified photographs of patchs tests
Patient affiliated to or benefiting from a social security regime
Protected patient: adult under guardianship, curatorship or other legal protection, deprived of liberty by judicial or administrative decision
Pregnant woman
Patients referred for suspected contact dermatitis to the Allergology and Clinical Immunology Department of the Centre Hospitalier Lyon Sud and the Dermatology and Allergology Department of the Centre Hospitalier Universitaire de St Etienne, with allergic contact dermatitis history and requiring patch test during their care pathway
Cohort
Prospective
The patch under study is photographed using the SkinCam®
Other interventionUnlike standard care, the patch under study is photographed using the SkinCam® and not a standard camera. The shooting and photographic remain similar to that of standard care, with only the camera used being changed.
