    Clinical correlations of recent developments in the pathogenesis of atopic dermatitis
    (Scielo, 2008-02) Sehra, Sarita; Holbreich, Mark; Kaplan, Mark H.; Tuana, Florencia M. Barbé; Mousdicas, Nico; Travers, Jeffrey B.; Pediatrics, School of Medicine
    Atopic dermatitis is a chronic inflammatory skin disease with a steadily increasing prevalence affecting 10-20 of infants and 1-3 of adults globally. It is often the first clinical manifestation of atopic disease preceding asthma and allergic rhinitis. Probably half of the children with atopic dermatitis develop some other form of atopic disease later in life. The pathogenesis involves a complex interplay of factors including genetic predisposition due to altered immune or skin barrier function, interactions with the environment such as food and allergen exposures, and infectious triggers of inflammation. In this review, we summarize the recent advances in understanding the contribution of different factors in the pathophysiology of atopic dermatitis and how insights provide new therapeutic potential for its treatment.

    Eruptive Disseminated Porokeratosis Associated with Corticosteroid-Induced Immunosuppression
    (Wiley, 2015-10) Bednarek, Robert; Ezra, Navid; Toubin, Yulianna; Linos, Konstantinos; Mousdicas, Nico; Department of Dermatology, IU School of Medicine
    Eruptive disseminated porokeratosis (EDP) is a disease that presents clinically with sudden onset of erythematous papules and plaques, with a ridge-like border histologically represented by a cornoid lamella. We report a case of EDP occurring in a 39-year-old woman 3 days after completion of a 2-week course of oral corticosteroid therapy for an acute asthma exacerbation. The patient was treated with emollients and sun protection. Unlike the more chronic disseminated superficial (actinic) porokeratosis, EDP secondary to immunosuppression from corticosteroid therapy has very rarely been reported in the dermatological literature.

    Pediatric positional sitting dermatitis: a new form of pediatric contact dermatitis
    (Wiley, 2016-05) Isaacs, Michael J.; Strausburg, Matthew B.; Mousdicas, Nico; Department of Dermatology, IU School of Medicine
    We report on four pediatric patients who presented with localized dermatitis in areas subject to repetitive friction due to their sitting positions. We propose that the cause of the eruption was irritant contact dermatitis due to frequently sitting in a crossed-leg sitting position, an entity for which we have coined the term pediatric positional sitting dermatitis (PPSD). The goal of this report is to raise clinicians' awareness of PPSD, which to our knowledge has not been previously described, and to discuss management of these patients.

    Rosacea Fulminans Precipitated by Acute Stress: A Case Report Describing an Integrative Approach for a Patient Reluctant to Use Isotretinoin
    (InnoVision Health Media, 2016-12) Veerkamp, Patrick; Mousdicas, Nico; Bednarek, Robert; Department of Dermatology, IU School of Medicine
    CONTEXT: Rosacea fulminans is a rare skin disorder with a multifactorial etiology. Stress is one of the common precipitating factors of this condition but is not often targeted in treatment. Isotretinoin is considered part of the first-line therapy for this condition but, in cases where its use is restricted, other therapeutic interventions as part of an integrative approach may be effective. PATIENT CONCERNS: A 38-y-old female presented with rosacea fulminans brought on by an acutely stressful event. After multiple failed therapies, she experienced resolution of her symptoms with a combination of systemic corticosteroids, antibiotics, diet modification, and stress reduction, with the treatment of stress playing a significant role. CONCLUSIONS: Stress management and diet modification are key adjunctive therapies in the treatment of rosacea fulminans and need to be addressed more often in treatment. In cases where patients are reluctant or unable to take isotretinoin, an integrative approach may be effective in achieving symptomatic improvement.

    Treatment of estrogen-induced dermatitis with omalizumab
    (Elsevier, 2019-05-25) Ocana, Jesus A.; Bell, Maria C.; Heskett, Jordan B.; Baker, William H.; Mousdicas, Nico; Turner, Matthew J.; Dermatology, IU School of Medicine
    In 1945, Drs Bernhard Zondek and Yehuda Bromberg demonstrated intradermal treatment with estrone and estradiol benzoate induced urticarial lesions in some patients.1 Fifty years later, Shelley et al,2 who introduced the concept of progesterone dermatitis several decades prior, defined estrogen dermatitis based on studies of 7 women with premenstrual flares of skin eruptions including papulovesicular, urticarial, or eczematous lesions or generalized pruritus. Previously described therapies for estrogen dermatitis include estrogen desensitization, tamoxifen, leuprolide, and oophorectomy.3 Here we report a case of estrogen-induced dermatitis successfully treated with omalizumab.
