Clinical Utility of a Digital Dermoscopy Image-Based Artificial Intelligence Device in the Diagnosis and Management of Skin Cancer by Dermatologists.

Background: Patients with skin lesions suspicious for skin cancer or atypical melanocytic nevi of uncertain malignant potential often present to dermatologists, who may have variable dermoscopy triage clinical experience.

Objective: To evaluate the clinical utility of a digital dermoscopy image-based artificial intelligence algorithm (DDI-AI device) on the diagnosis and management of skin cancers by dermatologists.

Methods: Thirty-six United States board-certified dermatologists evaluated 50 clinical images and 50 digital dermoscopy images of the same skin lesions (25 malignant and 25 benign), first without and then with knowledge of the DDI-AI device output.

Treatment burden and the perspectives of patients with psoriasis using topical treatments: results from a national survey of adults with psoriasis in the United States.

Background: Topical treatments are the foundation for patients with psoriasis; however, adherence can be limited by patient preferences and treatment burden.

Methods: The Harris Poll conducted an online survey of US patients with psoriasis who use prescription topical therapy to examine their preferences and perspectives on topical treatments.

Results: Among patients with psoriasis who use topical treatment ( = 507), most participants described their psoriasis symptoms as mild (31%) or moderate (59%).

Revolutionizing Skin Cancer Triage: The Role of Patient-Initiated Teledermoscopy in Remote Diagnosis.

Introduction: Teledermatology, defined as the use of remote imaging technologies to provide dermatologic healthcare services to individuals in a distant setting, has grown considerably in popularity since its widespread implementation during the COVID-19 pandemic. Teledermoscopy employs a smartphone dermatoscope attachment paired with a smartphone camera to visualize colors and microstructures within the epidermis and superficial dermis that cannot be seen with the naked eye ABCD criteria alone.

Methods: Our retrospective observational cohort and case-control study evaluated the utility of loaning a smartphone dermatoscope attachment to patients for remote triage of self-selected lesions of concern for skin cancer.

Patient Perspectives on the Prevalence and Burden of Intertriginous Psoriasis: Results from a National Survey of Adults with Psoriasis in the United States.

Introduction: A survey was conducted by The Harris Poll on behalf of Arcutis Biotherapeutics in the USA to understand perspectives and burden of patients with psoriasis using prescription topical treatments for their disease. This manuscript presents results from the subset of patients with intertriginous psoriasis.

Methods: The survey was conducted online October 21-November 24, 2021, among 507 US adults aged 18+ years with psoriasis diagnosed by a healthcare provider and currently using prescription topical treatment.

What can inherited immunodeficiencies reveal about pyoderma gangrenosum?

Pyoderma gangrenosum (PG) is a rare ulcerative neutrophilic dermatosis that is occasionally associated with primary immunodeficiency. Though contributions from dysregulation of the innate immune system, neutrophil dysfunction and genetic predisposition have been postulated, the precise pathogenesis of PG has not yet been elucidated. This article reviews reported cases of coexisting PG and primary immunodeficiency in order to gain insight into the complex pathophysiology of PG.

Malignant T Cell Activation by a Species Isolated from Cutaneous T-Cell Lymphoma Lesions.

Cutaneous T-cell lymphoma (CTCL) is a life-debilitating malignancy of lymphocytes homing to the skin. Although CTCL is thought to arise from a combination of genetic, epigenetic, and environmental factors, specific triggers are unclear. The skin is colonized by a unique microbiota and is heavily influenced by its interactions.

Patient Experience Surveys Reveal Gender-Biased Descriptions of Their Care Providers.

Patient experience surveys (PES) are collected by healthcare systems as a surrogate marker of quality and published unedited online for the purpose of transparency, but these surveys may reflect gender biases directed toward healthcare providers. This retrospective study evaluated PES at a single university hospital between July 2016 and June 2018. Surveys were stratified by overall provider rating and self-identified provider gender.

Low-dose methotrexate in dermatology: the utility of serological monitoring in a real-world cohort.

When prescribing low-dose methotrexate, frequent serological testing is recommended in the dermatologic literature, although much of the supporting data is extrapolated from non-dermatologic conditions. We performed a retrospective cohort study to determine the cumulative incidence and timing of low-dose methotrexate-associated serological abnormalities over the first year of therapy, in a pragmatic cohort of patients with dermatologic compared to non-dermatologic diagnoses. Laboratory values recorded included white blood cell count, hemoglobin, platelet count, estimated glomerular filtration rate, alanine aminotransferase, and aspartate aminotransferase.

Shared Decision-making in Dermatology: A Scoping Review.

Importance: Shared decision-making (SDM) can improve the quality of care for patients. The extent to which this tool has been used and the evidence supporting its use in dermatology have not been systematically examined.

Objective: To perform a scoping review of the literature regarding SDM in dermatology.

Synergistic induction of IL-23 by TNFα, IL-17A, and EGF in keratinocytes.

IL-23 is an inflammatory cytokine that plays an essential role in Th17 immunity by enhancing Th17 cell proliferation and survival, and Th17 cytokine production. IL-23 has pathogenic roles in the development of Th17-mediated inflammatory diseases including psoriasis. Despite successful treatment of psoriasis by blocking IL-23, the regulation of IL-23 expression in psoriasis patients is largely unknown.
