Contact Dermatitis

The goal of this clinical trial is to ensure that contact dermatitis does not prevent any person with diabetes from accessing optimal diabetes treatment. The main questions this study aims to answer are: How many pediatric patients with diabetes device-related contact dermatitis experience recurrence of contact dermatitis depending on the type of patch used underneath their device? Is one type of patch (silicone-based or hydrocolloid) more effective than the other at preventing contact dermatitis? The study population consists of children and adolescents aged 2-18 years with contact dermatitis (CD) caused by either an insulin pump or a continuous glucose monitor (CGM). Participants will be asked to complete questionnaires about their well-being and attend three in-person study visits. During these visits, the following assessments will be performed: Clinical skin examination Skin photographs of the most recently used insulin pump site, CGM site, and any reported skin reactions Measurement of height and weight Blood sample for measurement of long-term blood glucose (HbA1c) and filaggrin gene mutations Interview about skin reactions and related symptoms Skin ultrasound Tape stripping of the skin Electrical impedance spectroscopy (EIS), a non-invasive technique that transmits a harmless electrical signal through the skin

The goal of this clinical trial is to learn if a novel barrier topical product works to treat barrier dysfunction in adults. It will also learn about the safety of the novel barrier topical product. The main questions it aims to answer are: Does the novel barrier topical product improve skin hydration, skin sebum, redness, and pigmentation? Does it improve subjective dryness and itch? Researchers will compare the novel barrier topical product to petrolatum (a gold standard occlusive barrier repair agent) to see how they are comparable in treating skin barrier dysfunction. Participants will: Apply the novel barrier topical product or petrolatum twice a day for 28 days Visit the clinic once a week for checkups and tests Keep a diary of their application of the assigned product
