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 …

Review Of Applications Of Microneedling In Dermatology., Christopher Iriarte, Olabola Awosika, Monica Rengifo-Pardo, Alison Ehrlich

Dermatology Faculty Publications

Microneedling (MN) is a novel therapeutic modality in dermatology. Through physical trauma from needle penetration, MN induces a wound healing cascade with minimal damage to the epidermis. This allows for enhancement in the absorption of mainstay topical therapies across the thick stratum corneum. MN has become increasingly utilized over the last several years as it is a relatively simple procedure that is cost-effective, well tolerated, and offers both cosmetic and therapeutic benefits. The ability to treat localized areas of disease has led to numerous studies gauging its potential in focal diseases of inflammation, dyschromia, and photodamage. This review discusses the …

Sustained Nitric Oxide-Releasing Nanoparticles Interfere With Methicillin-Resistant Staphylococcus Aureus Adhesion And Biofilm Formation In A Rat Central Venous Catheter Model., Mircea Radu Mihu, Vitor Cabral, Rodney Pattabhi, Moses T Tar, Kelvin P Davies, Adam J Friedman, Luis R Martinez, Joshua D Nosanchuk

Dermatology Faculty Publications

Staphylococcus aureus is frequently isolated in the setting of infections of indwelling medical devices, which are mediated by the microbe's ability to form biofilms on a variety of surfaces. Biofilm-embedded bacteria are more resistant to antimicrobial agents than their planktonic counterparts and often cause chronic infections and sepsis, particularly in patients with prolonged hospitalizations. In this study, we demonstrate that sustained nitric oxide-releasing nanoparticles (NO-np) interfere with S. aureus adhesion and prevent biofilm formation on a rat central venous catheter (CVC) model of infection. Confocal and scanning electron microscopy showed that NO-np-treated staphylococcal biofilms displayed considerably reduced thicknesses and bacterial …

Systemic Sclerosis: Clinical Manifestations, Anesthetic And Orthopedic Considerations In A Patient, Obada Hasan, Muneeba Jessar, Muhammad Ashar, Shahryar Noordin, Tashfeen Ahmad

Section of Orthopaedic Surgery

Introduction: Systemic sclerosis is a rare and progressive multisystem autoimmune disorder that is characterized pathologically by vascular abnormalities, connective tissue sclerosis and atrophy of skin and various internal organs (e.g., alimentary tract, lungs, heart, kidney, CNS), and autoantibodies. With an unknown etiology, Scleroderma is a complex polygenetic disease. A recent Genome Wide Association Study (GWAS) confirmed a strong association with the Major Histocompatibility Complex (MHC) and autoimmunity. We provide a case scenario along with a review of the systems involved and challenges physicians can face in dealing with this rare disease.
Case Presentation: Our patient, a known case of systemic …

Promotion Of Skin Protection In Children In Waterbury, Vt, Kelsey M. Sullivan

Family Medicine Clerkship Student Projects

Background: Vermont has among the highest rates of skin cancer in the nation. Between 2001 and 2005, Vermont had the highest incidence of melanoma of any state, 63% higher than the national average. It is also estimated that if children under 18 regularly used sunscreen of at least SPF 15, the incidence of squamous and basal cell carcinomas would decrease by 78%. Modeling by the EPA and CDC suggests that recommended sun protection measures could prevent 11,000 cases of skin cancer, 50 deaths, and $30 million in cancer treatment costs nationwide. Intervention: To create an information sheet on skin protection …

Department of Medicine

Background:The vector-borne cutaneous leishmaniasis (CL) is endemic in several regions of Pakistan mainly affecting poor populations. Host genetic factors, particularly SLC11A1 (solute carrier transmembrane protein) within macrophages, play a crucial role in disease pathology and susceptibility. Association of SLC11A1 with cutaneous leishmaniasis, a neglected tropical disease, is not well established. Inconsistencies have been observed within different populations worldwide with respect to genetic susceptibility. This study was designed to investigate genetic variation(s) in SLC11A1 and to assess possible association with cutaneous leishmaniasis in Pakistan.

Results: Eight polymorphisms (rs2276631, rs3731864, rs2290708, rs2695342, rs201565523, rs17215556, rs17235409, rs17235416) were genotyped across SLC11A1 in …

In Vitro Three-Dimensional Skin Tissue Constructs, Tinashe Dereck Gombedza

Theses

Human skin provides fortification against peripheral threats which may compromise the integrity and health of the human body. Its presence as the largest human organ forms a protective barrier making it an effective first line of defence against pathogenic, chemical and physical damage. Tissue engineering technology has enabled the development of in vitro three-dimensional (3D) organotypic skin cultures in order to understand the skin's physiology and architecture. This advancement has enabled the use of 3D skin model platforms to study skin diseases and conditions as well as facilitate drug discovery, clinical research and cosmetic product development.

In this study, an …
