A quick infographic on various pearls about atopic dermatitis, a disease with an increasing burden on medicine and the patient. Herein, viewers can learn about possible risk factors, management recommendations, treatments, and comorbidities of atopic dermatitis. Atopic Dermatitis (AD) is a chronic, relapsing, inflammatory skin disease, affecting greater than 15% of children worldwide. This disease imposes a considerable burden on the physical, mental, and overall well-being of the patient. A combination of dysfunction of the skin barrier, cytokines, chemokines, and receptors in the skin result in the development of AD. #management #medications #treatment #diagnosis #causes #atopy #atopic #dermatitis #eczema #dermatology #skinrash References: Danby SG, Brown K, Wigley AM, et al.
