Guttate Psoriasis Following COVID-19 Infection.

Guttate psoriasis is a subgroup of psoriasis that most commonly presents as raindroplike, erythematous, silvery, scaly papules. Guttate psoriatic flares may follow rhinovirus or COVID-19 infection due to dysregulation of the innate immune response. We describe the case of a patient who experienced a moderate psoriatic flare 3 weeks after diagnosis of SARS-CoV-2 infection.

Rate of change of carotid intima-media thickness with magnesium administration in Abcc6⁻/⁻ mice.

Pseudoxanthoma elasticum (PXE), caused by mutations in the ABCC6 gene, demonstrates progressive build-up of calcium phosphate and proteoglycans in the skin, eye, and arteries, and is associated to myocardial infarctions, stroke, blindness, and elevated carotid intima-media thickness (CIMT). Although CIMT reduction with magnesium (Mg) has been documented in a mouse model for PXE (Abcc6(-/-) ), it is not clear if Mg is effective in humans with PXE to reduce CIMT. To examine this, we calculated the rate of change of CIMT (washout) in 15- and 12-month-old Abcc6(-/-) mice fed standard rodent diet with or without Mg supplementation for 2 months.

The prevalence of systemic diseases associated with dermatoses and stroke in the United States: a cross-sectional study.

Aims: To evaluate the prevalence of systemic diseases associated with dermatoses and conventional risk factors in patients with acute ischemic stroke (AIS). We hypothesized that conventional risk factors would not be overrepresented in AIS admissions of patients with dermatoses.

Methods: Cross-sectional study.

Psoriasis vulgaris: an evidence-based guide for primary care.

Psoriasis vulgaris is a chronic, sometimes debilitating, inflammatory disorder with multiple pathways of pathogenesis that can be associated with metabolic and cardiovascular disease. This article aims to be a comprehensive, literature-based review of the epidemiology, genetic factors, clinical diagnosis, treatments, and pharmacology for psoriasis as derived from articles published in PubMed. Levels of evidence and recommendations were made according to the strength of recommendation taxonomy.

The diagnostic evaluation of MelaFind multi-spectral objective computer vision system.

Introduction: Over 75,000 people in the United States were diagnosed with melanoma in 2012. The incidence of melanoma continues to increase over time and early detection is currently the most promising strategy to decrease melanoma-related morbidity and mortality. Currently, most physicians perform skin cancer screenings with the unaided eye.

Signaling through purinergic receptors for ATP induces human cutaneous innate and adaptive Th17 responses: implications in the pathogenesis of psoriasis.

Human cutaneous dendritic cells (DCs) have the ability to prime and bias Th17 lymphocytes. However, the factors that stimulate cutaneous DCs to induce Th17 responses are not well known. Alarmins, such as ATP, likely play a pivotal role in the induction and maintenance of cutaneous immune responses by stimulating DC maturation, chemotaxis, and secretion of IL-1β and IL-6, Th17-biasing cytokines.

Anti-cytokine therapy in the treatment of psoriasis.

Psoriasis is a chronic, inflammatory skin disease with many associated co-morbidities including diabetes, hypertension, obesity, psoriatic arthritis, and cardiovascular disease. It has long been known that psoriasis is a T cell-mediate disease and recent findings further demonstrate the important roles of the Th17 and Th22 arms of the immune system in the pathogenesis of psoriasis. Our understanding of this disease has progressed greatly and agents that target the cytokines involved in disease activity are under development or currently being used to treat psoriasis.
