Skin allergies are common globally and often frustrating to diagnose.
But new technology could soon help change that.
Dr Alison Bruce, a dermatologist at Mayo Clinic, is aiding the development of an artificial intelligence (AI)-powered tool to support allergy patch testing.
The tool is being designed to help patients self-apply test patches and use their smartphones to capture images over time, with technology offering guidance that could assist clinicians in diagnosis.
It’s a promising step toward faster, easier and more accessible skin allergy care, especially for people in rural areas or those with limited access to specialists.
Itchy skin.
Swollen patches.
A red, angry rash.
Skin allergies impact nearly one in five people.
“That is when a substance comes into contact with the skin and causes a reaction,” says Dr Bruce.
You may think of poison ivy triggering a reaction, but jewellery, fragrances, lotions and many more substances can cause a skin reaction known as contact dermatitis.
“What happens is the skin just turns red, itchy, flaky, scaly, kind of sometimes becomes fissured if it’s very severe, kind of becomes so red and inflamed that the skin breaks down and you get little cracks and crevices in the skin,” Dr Bruce says.
A new tool in development at Mayo Clinic aims to help patients and their healthcare team determine the cause of the reaction.
“We’ve been working on an AI tool to help with skin allergy testing because in the current state, if you as a patient or your doctor suspects that you have allergic contact dermatitis, the way to test for that would be through patch testing,” she says.
But testing can be time-consuming, requiring patients to return to the dermatologist’s office multiple times.
“The idea behind having AI is to enhance what we’re doing.
“Imagine a situation where instead of going into your dermatologist, you were able to put the patches on your skin yourself, remove them at a predetermined time and then use your cellphone and the camera on your cellphone to image those reactions.
“And then AI would be potentially able to interpret the reactions to: ‘Yes, there’s a red reaction that corresponds to nickel, and, therefore, you’re allergic to nickel,’” says Dr Bruce.
She says the new tool can improve the lives of those having skin reactions by making diagnosis more accessible and faster for patients.
“It can be done remotely. It can be done with imaging, AI interpretation, etc.
“It really broadens the reach of people who need care that can’t always make it to places like Mayo Clinic,” she adds. – Mayo Clinic News Network/ Tribune News Service
