    Hand Impairment in Systemic Sclerosis: Various Manifestations and Currently Available Treatment.
    Curr Treatm Opt Rheumatol 2016 Sep 19;2(3):252-269. Epub 2016 Jul 19.
    Division of Rheumatology, Department of Internal Medicine, University of Michigan, Ann Arbor, MI, USA; University of Michigan Scleroderma Program, Department of Internal Medicine, University of Michigan, Ann Arbor, MI, USA.
    Systemic sclerosis (SSc) is an autoimmune disease initially recognized by hand involvement due to characteristic Raynaud's phenomenon (RP), puffy hands, skin thickening, and contractures resembling claw deformities. SSc contributes to hand impairment through inflammatory arthritis, joint contractures, tendon friction rubs (TFRs), RP, digital ulcers (DU), puffy hands, skin sclerosis, acro-osteolysis, and calcinosis. These manifestations, which often co-exist, can contribute to difficulty with occupational activities and activities of daily living (ADL), which can result in impaired quality of life. Read More

    Nephrology Unit, Department of Clinical Medicine, Sapienza University of Rome, Viale dell'Università 37, 00161, Rome, Italy.
    An immunologic adjuvant is a substance that enhances the antigen-specific immune response preferably without triggering one on its own. Silicone, a synthetic polymer used for reconstructive and cosmetic purposes, can cause, once injected, local and/or systemic reactions and trigger manifestations of autoimmunity, occasionally leading to an overt autoimmune disease. Siliconosis, calcinosis cutis with hypercalcemia and chronic kidney disease have all been reported in association with silicone injection. Read More

    Calciphylaxis and Martorell Hypertensive Ischemic Leg Ulcer: Same Pattern - One Pathophysiology.
    Dermatology 2016 14;232(5):523-533. Epub 2016 Sep 14.
    Department of Dermatology, University Hospital of Zurich, Zurich, Switzerland.
    This review presents a closer look at four diseases which are probably closely related to one another pathophysiologically: (a) calciphylaxis (distal pattern); (b) calciphylaxis (proximal pattern); (c) Martorell hypertensive ischemic leg ulcer; (d) calciphylaxis with normal renal and parathyroid function (synonym: eutrophication). The four diseases have largely the same risk factors: (1) arterial hypertension, (2) diabetes mellitus (types 1 and 2), (3) secondary or tertiary hyperparathyroidism (in end-stage kidney disease) and (4) oral anticoagulation with vitamin K antagonists. They share the same clinical patterns: necrotizing livedo, skin infarctions at typical locations and acral gangrene in calciphylaxis. Read More
