Atopic dermatitis, commonly known as eczema, is a chronic inflammatory dermatosis that can affect individuals from infancy to adulthood. Also referred to as "the itch that rashes," atopic dermatitis is classically associated with significant pruritus that is accompanied by characteristic cutaneous and other clinical findings. The diagnosis of atopic dermatitis can be challenging due to the wide range of clinical presentations based on patient factors such as age, skin type, ethnicity, and other comorbid conditions. This chapter reviews the classical findings as well as the less common manifestations of atopic dermatitis.

The Role of Exosomes in Medical Dermatology: Literature Review and Update.
J Cosmet Dermatol
January 2025
Clinical Research Center of the Carolinas, Charleston, South Carolina, USA.
Background: Exosomes are extracellular vesicles, composed of a phospholipid bilayer, that are primarily derived from stem cells. The contents of exosomes can be incorporated into the tissue in which they are introduced, which presents a unique therapeutic option.
Aims: Exosomes have been investigated as a treatment for a number of medical ailments, but the literature supporting these indications is inconclusive.

: Atopic dermatitis (AD) is a chronic skin condition that weakens the skin barrier, leading to increased trans-epidermal water loss and reduced skin moisture. Understanding how these changes in the skin barrier relate to AD severity in Mongolian children may offer insights that could apply to other regions facing similar environmental challenges. : A cross-sectional study was conducted at the National Dermatology Center of Mongolia, involving 103 children with AD.

Research on the relationship between gut microbiota (GM) and atopic dermatitis (AD) has seen a growing interest in recent years. The aim of this systematic review was to determine whether differences exist between the GM of adults with AD and that of healthy adults (gut dysbiosis). We conducted a systematic review based on the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses).

Lipids are intimately associated with skin condition. This review aims to discuss the function of linoleic acid (LA, 18:2, ω-6), an essential fatty acid, in skin health and hair growth. In skin, LA can be metabolized into ω-6 unsaturated fatty acid, oxidized derivatives and incorporated into complex lipid molecules, including ω-hydroxy-ceramides.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder influenced by proteins involved in skin barrier maintenance and vitamin D metabolism. Using an intra-patient design, this study compared protein expression in intra-lesional (IL) and peri-lesional (PL) skin biopsies from AD patients and examined associations between protein levels, vitamin D status, and clinical features. Forty-four biopsies from twenty-two AD patients were analyzed using antibody microarrays targeting twelve proteins.
