Assessment of the Cutaneous Hormone Landscapes and Microbiomes in Vulvar Lichen Sclerosus.

Vulvar lichen sclerosus (VLS) is a progressive skin disease of unknown etiology. In this longitudinal case-control exploratory study, we evaluated the hormonal and microbial landscapes in 18 postmenopausal females (mean [SD] age: 64.4 [8.

Vulvar Lichen Sclerosus Clinical Severity Scales and Histopathologic Correlation: A Case Series.

Several vulvar lichen sclerosus (VLS) clinical severity scales have recently been proposed. In this prospective case series, we characterized histopathology in the context of clinical severity in 6 treatment-naïve postmenopausal patients with VLS. The Vulvar Quality of Life Index (VQLI) and an adaptation of the 2018 International Society for the Study of Vulvovaginal Disease Delphi consensus VLS severity score were administered.

Saprophytic bacteria and fungi colonize stearoyl coenzyme-A desaturase-1 knockout skin.

Lipids synthesized on the skin are critical to the antimicrobial barrier. Skin lipids also facilitate survival of lipophilic skin commensals in an otherwise dry and acidic ecological landscape. Thus, skin-specific stearoyl-coenzyme A desaturase 1 knockout mice (Scd1 ) with sebocyte atrophy and decreased synthesis of monounsaturated fatty acids, triglycerides and wax diesters have dry, inflamed skin.
