Introduction Of Probiotics To Improve Eczema Symptoms In Children In One Pediatric Primary Care Practice: A Quality Improvement Project, Christie Potter

Doctor of Nursing Practice Scholarly Projects

Background: There is emerging interest in alternative approaches to treating children with eczema because there is currently no allopathic cure. Non-pharmacological approaches are regarded as generally safe, well tolerated, and cost effective. Eczema is a chronic, relapsing inflammatory, itchy skin condition that adversely affects quality of life in many individuals, including children. Eczema interferes with sleep, leads to secondary skin infections, and causes intractable itching. Topical steroids are the current standard of practice in treating patients but, evidence suggests that they can cause unwanted side effects and can lead to serious systemic reactions. The purpose of this quality improvement project …

Adipocytes And Innate Immunity In Systemic Sclerosis, Nancy Wareing

Dissertations and Theses (Open Access)

Systemic sclerosis (SSc; scleroderma) is a chronic systemic autoimmune and connective tissue disorder characterized by vasculopathy, autoimmune phenomena, and widespread fibrosis. Skin thickening and tightening is the cardinal feature of SSc and is responsible, in part, for the considerable morbidity of this disease. There are currently no targeted treatments for skin manifestations in SSc, primarily due to our fragmented understanding of its pathophysiologic mechanisms. In PART I, we report a previously unappreciated link between aberrant expression of the developmental gene sine oculis homeobox homolog 1 (SIX1) in skin-associated adipocytes in SSc skin and the early loss of dermal white adipose …

Complete Clearance Of Pustular Psoriasis After A Single Dose Of Risankizumab, Ashleigh E. Hermann, Stephen E. Weis

HCA Healthcare Journal of Medicine

Introduction

Psoriasis is a chronic, multifactorial, inflammatory skin disease with several subtypes, including pustular psoriasis. Pustular psoriasis is characterized by pustules forming lakes of pus on the skin. Pro-inflammatory pathways, such as the interleukin (IL)-17/IL-23 axis, have been shown to play a significant role in the pathogenesis of psoriasis. Biologic therapies directed towards these pro-inflammatory pathways have effectively treated plaque psoriasis, but fewer treatments have shown similar efficacy for pustular psoriasis.

Case Presentation

We present a 45-year-old Black female who presented to the dermatology clinic with generalized pustular psoriasis affecting approximately 70% of her body surface area. She also noted …

Accidental Extravasation Of Mitomycin C Into The Subcutaneous Tissue, Johnathon Chung, Brooke Walterscheid, Jose Lopez-Vera, Hytham Rashid, Mike K. Liang

HCA Healthcare Journal of Medicine

Introduction

Mitomycin C (MMC) is a common chemotherapeutic agent used to treat a variety of solid tumors. Cutaneous adverse events are rare, but MMC is a known vesicant reported to cause tissue necrosis and sloughing, erythema, and ulceration if incorrectly infused into the subcutaneous tissue. Definitive treatment of extravasation injuries due to MMC depends on the severity of the cutaneous manifestation, which includes stopping the infusion, removing the catheter, or possible debridement.

Case Presentation

We present the case of a 70-year-old female with extensive soft-tissue injury secondary to extravasation of MMC that required hospital admission and surgical intervention to remove …

Trametinib-Induced Epidermal Thinning Accelerates A Mouse Model Of Junctional Epidermolysis Bullosa, Grace Tartaglia, Pyung Hung Park, Michael H. Alexander, Alexander Nyström, Joel Rosenbloom, Andrew P. South

Department of Dermatology and Cutaneous Biology Faculty Papers

Junctional epidermolysis bullosa (JEB) patients experience skin and epithelial fragility due to a pathological deficiency in genes associated with epidermal adhesion. Disease severity ranges from post-natal lethality to localized skin involvement with persistent blistering followed by granulation tissue formation and atrophic scarring. We evaluated the potential of utilizing Trametinib, an MEK inhibitor previously shown to target fibrosis, with and without the documented EB-anti-fibrotic Losartan for reducing disease severity in a mouse model of JEB; Lamc2jeb mice. We found that Trametinib treatment accelerated disease onset and decreased epidermal thickness, which was in large part ameliorated by Losartan treatment. Interestingly, a range …

Zoster-Associated Prothrombotic Plasma Exosomes And Increased Stroke Risk, Andrew N Bubak, Christina Coughlan, Janelle Posey, Anthony J Saviola, Christy S Niemeyer, Serena W R Lewis, Sara Bustos Lopez, Adriana Solano, Stephen K Tyring, Cassidy Delaney, Keith B Neeves, Ravi Mahalingam, Kirk C Hansen, Maria A Nagel

Faculty, Staff and Student Publications

Herpes zoster (HZ; shingles) caused by varicella zoster virus reactivation increases stroke risk for up to 1 year after HZ. The underlying mechanisms are unclear, however, the development of stroke distant from the site of zoster (eg, thoracic, lumbar, sacral) that can occur months after resolution of rash points to a long-lasting, virus-induced soluble factor (or factors) that can trigger thrombosis and/or vasculitis. Herein, we investigated the content and contributions of circulating plasma exosomes from HZ and non-HZ patient samples. Compared with non-HZ exosomes, HZ exosomes (1) contained proteins conferring a prothrombotic state to recipient cells and (2) activated platelets …

Exploring Hapi Incidence In Patients Admitted Through The Ed: A Quality Improvement Initiative, Alexa L. Tietgens

DNP Projects

Each year in the U.S., pressure injuries, or PIs, are responsible for more than 60,000 patient deaths and billions of dollars’ worth of treatment costs. Research shows that roughly 95% of all PIs are preventable by following evidence-based practice guidelines which include early identification of patients at risk, frequent skin assessments, and implementation of prevention strategies. However, the ED environment creates unique risks for PI development due to the routine use of hard surfaces (i.e., stretchers, backboards, exam tables) and frequent hospital overcrowding. Although nurses play a pivotal role in PI prevention, frequent staffing shortages, high patient acuity levels, and …

Preparedness For And Management Of Conditions Of The Skin, Louis D. Mancano Md

Transformative Medicine

Over one-quarter of the US population seeks treatment for a dermatologic condition each year. Studies have indicated that the general medical school curriculum places little emphasis on diseases of the skin, and physicians may be ill-prepared to diagnose and manage these conditions. A better understanding of the seven corticosteroid classes and the variety of vehicles in which they are formulated may improve patient satisfaction, patient adherence, and clinical response to treatment when managing conditions of the skin.

Medical Student Research Symposium

Melanoma is a skin cancer that arises in melanocytes; it is the fifth most common cancer in the United States with approximately 100,000 new cases per year. Current treatments for malignant melanoma are surgical excision, radiation therapy and systemic therapy; however, the five-year survival rate for patients with stage IV is 29.8%. There is an urgent unmet clinical need to investigate novel treatments for these patients. Panobinostat is an orally available histone deacetylase inhibitor used in several hematologic malignancies, but it was ineffective as a single agent against melanoma in Phase 1. To address the insufficiency of options for melanoma …

Sun Protection Intervention For Urban Youth, Erika Polanco, Jordan Tall, Erin Caris, Arjun Muralidharan, Michael Escobar, Sofia Howson, Jason Liu, Alyssa Goodwin, Steven Daveluy

Medical Student Research Symposium

Introduction:

Skin cancer is less prevalent in persons with darker skin color compared to those with light skin, but contrarily is associated with greater mortality rates. Experts agree this is primarily due to late detection. Challenges in early detection include low public awareness, uncommon presentation, lower index of suspicion among health care providers, and decreased access to specialty care. To address some of these barriers, we designed a survey-based study to discover current beliefs, perceptions, and attitudes of urban youth towards sun protection before and after an educational intervention.

Methods:

In 2022, 17 children living in metro Detroit …

HPVs are DNA viruses include approximately 450 types that are classified into 5 genera (α-, β-, γ-, μ-, and ν-HPV). The γ- and β-HPVs are present in low copy numbers in healthy individuals; however, in patients with an inborn error of immunity, certain species of β-HPVs can cause epidermodysplasia verruciformis (EV), manifesting as recalcitrant cutaneous warts and skin cancer. EV presents as either typical or atypical. Manifestations of typical EV are limited to the skin and are caused by abnormal keratinocyte-intrinsic immunity to β-HPVs due to pathogenic sequence variants in TMC6, TMC8, or CIB1. We applied a transcriptome-based computational pipeline, …
