Considerations For The Use Of Medical Devices In Dermatology., Jordan Wang, Dorota Z. Korta, Christopher B. Zachary

Department of Dermatology and Cutaneous Biology Faculty Papers

This manuscript addresses the significant considerations concerning the development and use of medical devices in dermatology. With the rapidly growing demand and booming market for medical devices, especially lasers, it is crucial that dermatologists become familiar with the nuances associated with supporting clinical studies, consumer-driven marketing strategies, and the complex relationships that exist between physicians, industry, and consumers. An examination of these relationships includes an overview of the potential biases pertaining to advisory panels and treating clinicians. The aim of this paper is to serve as an introduction to the background of medical devices and to offer dermatologists important information …

Fungus Amungus -- A Common Disease State That Is Commonly Missed: A Survey Based Study, Ramsin Yadgar, Adam Friedman, Neal Bhatia

GW Research Days 2016 - 2020

Background: Dermatophyte infections involving the skin, hair, or nails affect an estimated 25% of the world's population, and accounted for 51 million outpatient visits over a ten-year period (1995-2004) in the United States alone. Dermatomycosis is routinely managed by dermatologists, though given the diversity of clinical presentations, is sometimes misdiagnosed, which can result in inappropriate therapy, worsening of symptoms, and even result in additional skin and soft tissue infections.

Methods: An interactive survey of board-certified dermatologists was conducted at the 2016 Orlando Dermatology Aesthetic & Clinical Conference, during a seminar on superficial mycotic infections. The structure of the survey entailed …

Thin Melanoma With Nodal Involvement: Analysis Of Demographic, Pathologic, And Treatment Factors With Regard To Prognosis., Giorgos Karakousis, Phyllis A Gimotty, Edmund K Bartlett, Myung-Shin Sim, Madalyn G Neuwirth, Douglas Fraker, Brian J Czerniecki, Mark B Faries

Articles, Abstracts, and Reports

BACKGROUND: Although only a small proportion of thin melanomas result in lymph node metastasis, the abundance of these lesions results in a relatively large absolute number of patients with a diagnosis of nodal metastases, determined by either sentinel lymph node (SLN) biopsy or clinical nodal recurrence (CNR).

METHODS: Independent cohorts with thin melanoma and either SLN metastasis or CNR were identified at two melanoma referral centers. At both centers, SLN metastasis patients were included. At center 1, the CNR cohort included patients with initial negative clinical nodal evaluation followed by CNR. At center 2, the CNR cohort was restricted to …

Adverse Reactions Of Biological Therapies In Patients With Psoriasis, Maria I. Sârbu, Mircea Tampa, Mădălina I. Mitran, Cristina I. Mitran, Alexandra M. Limbău, Simona R. Georgescu

Journal of Mind and Medical Sciences

Psoriasis is a chronic, immune-mediated disorder characterized by well demarcated, erythematous plaques covered by thick, silvery-white scales, most often located on the knees, elbows, sacral area and scalp. It has a significant impact on the patient's quality of life.

Biological therapies revolutionized the treatment of psoriasis vulgaris but there has been concern regarding the use of those agents due to severe adverse reactions reported in patients receiving TNF-α inhibitors for various inflammatory diseases.

The aim of this paper is to review the most important adverse reactions reported in patients receiving biological treatments. The most common and severe side effects associated …

Atr Mutations Promote The Growth Of Melanoma Tumors By Modulating The Immune Microenvironment., Chi-Fen Chen, Rolando Ruiz-Vega, Priya Vasudeva, Francisco Espitia, Tatiana B Krasieva, Sebastien De Feraudy, Bruce J Tromberg, Sharon Huang, Chad P Garner, Jie Wu, Dave S B Hoon, Anand K Ganesan

Articles, Abstracts, and Reports

Melanomas accumulate a high burden of mutations that could potentially generate neoantigens, yet somehow suppress the immune response to facilitate continued growth. In this study, we identify a subset of human melanomas that have loss-of-function mutations in ATR, a kinase that recognizes and repairs UV-induced DNA damage and is required for cellular proliferation. ATR mutant tumors exhibit both the accumulation of multiple mutations and the altered expression of inflammatory genes, resulting in decreased T cell recruitment and increased recruitment of macrophages known to spur tumor invasion. Taken together, these studies identify a mechanism by which melanoma cells modulate the immune …

The Influence Of Tumor Regression, Solar Elastosis, And Patient Age On Pathologists' Interpretation Of Melanocytic Skin Lesions., Linda Titus, Raymond L Barnhill, Jason P Lott, Michael W Piepkorn, David E Elder, Paul D Frederick, Heidi D Nelson, Patricia A Carney, Stevan R Knezevich, Martin A Weinstock, Joann G Elmore

Articles, Abstracts, and Reports

It is not known whether patient age or tumor characteristics such as tumor regression or solar elastosis influence pathologists' interpretation of melanocytic skin lesions (MSLs). We undertook a study to determine the influence of these factors, and to explore pathologist's characteristics associated with the direction of diagnosis. To meet our objective, we designed a cross-sectional survey study of pathologists' clinical practices and perceptions. Pathologists were recruited from diverse practices in 10 states in the United States. We enrolled 207 pathologist participants whose practice included the interpretation of MSLs. Our findings indicated that the majority of pathologists (54.6%) were influenced toward …

Challenges To Smartphone Applications For Melanoma Detection, Jordan V. Wang, Lance W. Chapman, Matthew S. Keller

Department of Dermatology and Cutaneous Biology Faculty Papers

This commentary addresses the emerging market for health-related smartphone applications. Specific to dermatology, there has been a significant increase not only in applications that promote skin cancer awareness and education but also in those meant for detection. With evidence showing that 365 dermatology-related applications were available in 2014--up from 230 in 2012--and that 1 in 5 patients under the age of 50 have used a smartphone to help diagnose a skin problem, there is clearly a large subset of patients participating in this growing trend. Therefore, we are obligated to take a closer look into this phenomenon. Studies have shown …

Ladarixin, A Dual Cxcr1/2 Inhibitor, Attenuates Experimental Melanomas Harboring Different Molecular Defects By Affecting Malignant Cells And Tumor Microenvironment., Daria Marley Kemp, Alyson Pidich, Mary Larijani, Rebecca Jonas, Elizabeth Lash, Takami Sato, Mizue Terai, Maria De Pizzol, Marcello Allegretti, Olga Igoucheva, Vitali Alexeev

Department of Dermatology and Cutaneous Biology Faculty Papers

CXCR1 and CXCR2 chemokine receptors and their ligands (CXCL1/2/3/7/8) play an important role in tumor progression. Tested to date CXCR1/2 antagonists and chemokine-targeted antibodies were reported to affect malignant cells in vitro and in animal models. Yet, redundancy of chemotactic signals and toxicity hinder further clinical development of these approaches. In this pre-clinical study we investigated the capacity of a novel small molecule dual CXCR1/2 inhibitor, Ladarixin (LDX), to attenuate progression of experimental human melanomas. Our data showed that LDX-mediated inhibition of CXCR1/2 abrogated motility and induced apoptosis in cultured cutaneous and uveal melanoma cells and xenografts independently of the …
