    Psoriasis Induced by Anti-Tumor Necrosis Factor Alpha Agents: A Comprehensive Review of the Literature.
    Acta Dermatovenerol Croat 2016 Aug;24(3):169-74
    Prof. Massimo De Martinis, MD, Department of Life, Health AND Environmental Sciences, University of L'Aquila, L'Aquila, Italy;
    Tumor necrosis factor alpha (TNF-α) inhibitors revolutionized the management of patients affected by autoimmune diseases such as inflammatory bowel diseases, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and psoriasis. The biologic agents targeted to block TNF-α such as infliximab, adalimumab, certulizumab pegol, etanercept, and golimumab, have a good safety profile; however, with increasing, broader, and prolonged use, patients could be exposed to an increased risk of adverse reactions including a wide spectrum of dermatological conditions of different etiology and morphology. Among these, of particular interest is the development of skin immune-mediated diseases that seem to be the consequence of the paradoxical inflammation induced by anti-TNF-α therapy. Read More

    Background: Guttate psoriasis (GP) is characterized by acute onset of small, rounded psoriatic lesions. Although this particular phenotype of psoriasis is usually associated with streptococcal throat infections and mainly occurs in HLA-Cw6(+) patients, the specific immunologic response to this innate stimulus that causes these skin lesions is poorly understood.

    Objective: This study aims to elucidate how key cellular elements of patients with GP respond to Streptococcus pyogenes and whether this initial immune response is favored by the genetic and environmental background of these patients. Read More

    Tailor systemic therapy to the patient with severe psoriasis.
    Practitioner 2016 Feb;260(1790):23-6, 3
    There is no standard definition regarding the severity of psoriasis, and a number of factors should be considered, including the extent and stability of skin disease, involvement of joints, response to treatment, and impact on quality of life. Erythrodermic psoriasis and pustular psoriasis are severe conditions and the patient may be systemically unwell and febrile. NICE recommends that four key areas should be evaluated and recorded when assessing patients: severity, using the static Physician's Global Assessment (sPGA); disease impact on physical, psychological and social wellbeing using the Dermatology Life Quality Index (DLQI); the presence of psoriatic arthritis; and comorbidities.

    The practical usefulness of dermoscopy in general dermatology.
    G Ital Dermatol Venereol 2015 Oct 18;150(5):533-46. Epub 2015 Jun 18.
    Department of Experimental and Clinical Medicine Institute of Dermatology University of Udine, Udine, Italy -
    Beside to traditional use, dermoscopy is more and more used in the assessment of other "general" dermatologic conditions, namely scalp and hair disorders (trichoscopy), nails abnormalities (onychoscopy), skin infections and infestations (entomodermoscopy), and cutaneous inflammatory diseases (inflammoscopy). Among the list of new applications of dermoscopy, the study of inflammatory dermatoses is probably the most promising topic in terms of development and usefulness, considering the large number of such disorders and the frequent problems in their differential diagnosis which the dermatologist encounters in own daily clinical practice. In this paper, we report selected relatively common clinical differential diagnosis issues concerning inflammatory dermatoses (and some clinically related noninflammatory conditions), analysing them by a dermoscopic point of view in order to assist their noninvasive resolution according to the available literature data and our personal experience, including papulosquamous dermatoses (guttate psoriasis, pityriasis lichenoides chronica, pityriasis rosea, lichen planus, lymphomatoid papulosis, classic pityriasis rubra pilaris, papulosquamous sarcoidosis, disseminated forms of porokeratosis and papulosquamous chronic GVHD), dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides, subacute cutaneous lupus erythematosus), palmar psoriasis vs. Read More

    Differentiation of pityriasis lichenoides chronica from guttate psoriasis by dermoscopy.
    Clin Exp Dermatol 2015 Oct 16;40(7):804-6. Epub 2015 Feb 16.
    Department of Experimental and Clinical Medicine, Institute of Dermatology, University of Udine, Italy.
    Clinical differentiation between pityriasis lichenoides chronica (PLC) and guttate psoriasis (GP) may sometimes be a difficult task, which often requires histological analysis to reach a definitive diagnosis. In this study, PLC and GP lesions were examined using dermoscopy, and the significance of specific dermoscopic findings was investigated in order to facilitate their differentiation and decrease the number of cases requiring biopsy. We found that the incidence of orange-yellowish structureless areas, focal dotted vessels and nondotted vessels was statistically significant in PLC, while the incidence of diffuse dotted vessels was statistically significant in GP.
