    Investigating the roles of regulatory T cells, mast cells and interleukin-9 in the control of skin inflammation by vitamin D.
    Arch Dermatol Res 2018 Feb 1. Epub 2018 Feb 1.
    Telethon Kids Institute, University of Western Australia, 100 Roberts Rd, Subiaco, Perth, WA, 6008, Australia.
    Topical application of biologically active vitamin D [1,25-dihydroxyvitamin D (1,25(OH)D)], or low-calcemic analogues, curb skin inflammation through mechanisms that involve migratory dendritic cells (DCs) and regulatory T (T) cells. 1,25(OH)D also promotes immunoregulation by mast cells, and inhibits the development of T helper type-9 (Th9) cells that secrete interleukin-9 (IL-9). Here, we investigated the ability of topical 1,25(OH)D to suppress contact dermatitis through an IL-9-dependent process, examining mast cells and IL-9-secreting T cells. Read More

    Systemic contact dermatitis due to corrosion of titanium-coated nickel and cobalt bone plate fixation: A case report.
    Medicine (Baltimore) 2017 Dec;96(50):e9120
    Division of Allergy and Immunology, Department of Dermatology and Venereology, Faculty of Medicine, Universitas Padjadjaran-Dr. Hasan Sadikin Hospital, Bandung, Indonesia.
    Rationale: Corrosion refers to the degradation of a material that occurs following its interaction with other substances in the environment. Corrosion of metallic substances into tissues may lead to inflammatory responses such as systemic contact dermatitis (SCD), a skin condition where an individual who has previously been sensitized to a particular allergen via the cutaneous route will subsequently react to same allergen via the systemic route. This condition occurs following exposure to allergens such as metals, medications, and certain food substances. Read More

    Immunogenetics of cytokine genes in parthenium dermatitis: a review.
    Eur Ann Allergy Clin Immunol 2017 Nov 27. Epub 2017 Nov 27.
    Department of Biochemistry, All India Institute of Medical Sciences, New Delhi, India.
    Summary: Parthenium dermatitis is a chronic immuno-inflammatory, distressing skin disease and is mediated by activated T-lymphocyte which is primarily manifested on the exposed sites of the face, neck, hand and flexures. Parthenium hysterophorus is ubiquitous, hence it is diffi-cult to avoid the aero-allergenic antigen parthenin, responsible for the contact dermatitis. The pathogenesis of parthenium dermatitis is characterized by infiltration of T-lymphocytes into challenged skin sites and the development of a cutaneous inflammation due to altered regulatory network of pro and anti-inflammatory cytokines.

    Australas J Dermatol 2018 Jan 29. Epub 2018 Jan 29.
    Northern Clinical School, University of Sydney, Sydney, New South Wales, Australia.
    We present an unusual case where symptoms of headache and chest pain persisted for 3 years following the implantation of a septal occluder device for an atrial septal defect despite endothelialisation of the device. The patient was found to have nickel hypersensitivity on patch testing. Following the removal of the device the patient had complete resolution of headaches and chest pain up to 10 months post-explantation. Read More

    Lymphocyte surface markers and cytokines are suitable for detection and potency assessment of skin-sensitizing chemicals in an in vitro model of allergic contact dermatitis: the LCSA-ly.
    Arch Toxicol 2018 Jan 30. Epub 2018 Jan 30.
    Department of Internal Medicine, Bundeswehr Hospital, Scharnhorststraße 13, 10115, Berlin, Germany.
    Allergic contact dermatitis is a widespread health disorder and occupational skin disease. Hence, screening for contact-sensitizing chemicals is highly relevant to toxicology, dermatology, and occupational medicine. The use of animal tests for this purpose is constrained by ethical considerations, need for high-throughput screening, and legislation (e. Read More

    Cutting Edge: Nqo1 Regulates Irritant Contact Hypersensitivity against Croton Oil through Maintenance of Dendritic Epidermal T Cells.
    J Immunol 2018 Mar 29;200(5):1555-1559. Epub 2018 Jan 29.
    Department of Immunology and Pathology, Research Institute, National Center for Global Health and Medicine, Ichikawa-shi, Chiba 272-8516, Japan
    Irritant contact dermatitis (ICD) is associated with local release of inflammatory mediators such as reactive oxygen species and regulated by various antioxidative enzymes and antioxidants. Although Nqo1 is involved in antioxidative reactions and detoxification, its role in ICD remains unknown. Nqo1-deficient mice exhibited augmented ear swelling accompanied by neutrophil infiltration in the croton oil-induced mouse ICD model. Read More
