    Autoinflammatory keratinization diseases: An emerging concept encompassing various inflammatory keratinization disorders of the skin.
    J Dermatol Sci 2018 Feb 1. Epub 2018 Feb 1.
    Department of Dermatology, Fujita Health University School of Medicine, Toyoake, Japan.
    Classifying inflammatory skin diseases is challenging, especially for the expanding group of disorders triggered by genetic factors resulting in hyperactivated innate immunity that result in overlapping patterns of dermal and epidermal inflammation with hyperkeratosis. For such conditions, the umbrella term "autoinflammatory keratinization diseases" (AIKD) has been proposed. AIKD encompasses diseases with mixed pathomechanisms of autoinflammation and autoimmunity, and includes IL-36 receptor antagonist (IL-36Ra)-related pustulosis, CARD14-mediated pustular psoriasis, pityriasis rubra pilaris (PRP) type V, and familial keratosis lichenoides chronica (KLC).

    Incidence of diseases primarily affecting the skin by age group: population-based epidemiologic study in Olmsted County, Minnesota, and comparison with age-specific incidence rates worldwide.
    Int J Dermatol 2018 Jan 29. Epub 2018 Jan 29.
    Division of Clinical Dermatology, Mayo Clinic, Rochester, MN, USA.
    Understanding the effects of age on the epidemiology of diseases primarily affecting the skin is important to the practice of dermatology, both for proper allocation of resources and for optimal patient-centered care. To fully appreciate the effect that age may have on the population-based calculations of incidence of diseases primarily affecting the skin in Olmsted County, Minnesota, and worldwide, we performed a review of all relevant Rochester Epidemiology Project-published data and compared them to similar reports in the worldwide English literature. Using the Rochester Epidemiology Project, population-based epidemiologic studies have been performed to estimate the incidence of specific skin diseases over the past 50 years. Read More

    Possible role of plasmacytoid dendritic cells in pityriasis lichenoides.
    Clin Exp Dermatol 2018 Jan 19. Epub 2018 Jan 19.
    Department of Dermatology, American University of Beirut Medical Center, Beirut, Lebanon.
    Background: Plasmacytoid dendritic cells (pDCs) and their product, type I interferons (IFNs), have been implicated in the pathogenesis of several skin disorders characterized by an interface dermatitis (ID) pattern, such as lichen planus (LP). A type I IFN signature has previously been documented in pityriasis lichenoides (PL). Although pDCs are known to be the main source and most potent producers of local type I IFNs, their role in PL has not been investigated. Read More

    Service de dermatologie, hôpitaux universitaires de Genève (HUG), 1211 Genève, Suisse.
    Pityriasis rubra pilaris is a rare heterogeneous dermatosis associating three clinical signs to different degrees: follicular corneal papules, reddish-orange palmoplantar keratoderma and erythematosquamous lesions that may in some cases be very extensive, interspersed with patches of healthy skin. The aetiology is unclear, and in most cases, the trigger factors consist of trauma or infection, probably in subjects with an existing predisposition. In other cases, the condition is associated with immunological disorders or, in familial cases, genetic keratinisation abnormalities similar to ichthyosis. Read More
