Targeting Neuronal Nitric Oxide Synthase (Nnos) For Melanoma Treatment, Shirley Tong

Pharmaceutical Sciences (PhD) Dissertations

Human cutaneous melanoma is the most aggressive form of skin cancer and the incidence rates have continued to increase over the years. Neuronal nitric oxide synthase (nNOS) produces nitric oxide (NO) has been found to be overexpressed in human melanoma and the expression of nNOS is induced by interferon-gamma (IFN-γ). In our studies, nNOS has been implicated in IFN-γ-stimulated melanoma progression and the inhibition of nNOS using novel inhibitors effectively inhibited IFN-γ-stimulated tumor growth in a xenograft mouse model. Programmed death-ligand 1 (PD-L1) is overexpressed in melanoma and plays an important role in suppressing the immune system ^12-14. Our …

New Practical Aspects Of Sweet Syndrome, Tejas P Joshi, Sarah K Friske, David A Hsiou, Madeleine Duvic

Faculty, Staff and Student Publications

Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, is an inflammatory, non-infectious skin reaction characterized clinically by tender, erythematous papules/plaques/pustules/nodules commonly appearing on the upper limbs, trunk, and head and neck; histologically, SS is characterized by dense neutrophilic infiltrate in the dermis. SS is accompanied by fever; an elevation of inflammatory markers (e.g., erythrocyte sedimentation rate, C reactive protein) in serum may also be observed. Although most cases of SS are idiopathic, SS also occurs in the setting of malignancy or following administration of an associated drug. SS has also been reported in association with pregnancy and a burgeoning list …

Association Of Flame-Retardant Clothing With Mycosis Fungoides: A Retrospective Analysis, Katherine E Park, Vignesh Ramachandran, Jessica Tran, Tejas P Joshi, Naveen Garg, Madeleine Duvic

Faculty, Staff and Student Publications

Introduction: Mycosis fungoides (MF), the most prevalent form of cutaneous T-cell lymphoma (CTCL), has been associated with a variety of environmental and occupational exposures. Flame-retardant clothing (FRC), in contrast to flame-resistant clothing, is chemically treated and may constitute a previously unrecognized occupational hazard.

Objectives: To report an association between FRC and MF.

Methods: After encountering several young male patients whose onset of MF coincided with the occupational use of FRC and occupation as fire fighters, we did a retrospective search. Additional biopsy proven MF patients with use of FRC were identified by the EPIC electronic medical record using the search …

HCA Healthcare Journal of Medicine

Alopecia of the scalp has various causes and presentations. However, linear alopecia is unusual and lupus erythematosus presenting as linear alopecia is exceedingly rare. To date, there have been 16 documented cases of linear alopecia diagnosed as chronic cutaneous lupus erythematosus occurring in a linear configuration following Blaschko's lines. We report 2 additional cases and review the clinical and histologic features along with treatment. This Blaschkoid linear variant of cutaneous lupus erythematosus has distinct clinical and histologic characteristics that set it apart from other causes of alopecia and from classic forms of cutaneous lupus. These distinct features include a linear …

Mathematics & Statistics Faculty Publications

Background

Several studies conducted in Europe have suggested a protective association between early-life farming exposure and childhood eczema or atopic dermatitis; however, few studies have examined associations in adults.

Objectives

We investigated associations between early-life exposures and eczema among 3217 adult farmers and farm spouses (mean age, 62.8 years) in a case–control study nested within an US agricultural cohort.

Methods

We used sampling-weighted logistic regression to estimate odds ratios and 95% confidence intervals for associations between early-life exposures and self-reported doctor-diagnosed eczema (273 cases) and polytomous logistic regression to estimate odds ratios (95% confidence intervals) for a 4-level outcome combining …

Incidence And Potential Co-Morbidities In Facial Pigmentary Demarcation Lines In Indian Populations, Lakkireddygari Sujana, Savitha L. Beergouder, Alekhya Rallapalli, Sujatha Alla, Prasanthi Chidipudi

Engineering Management & Systems Engineering Faculty Publications

Background: The most noticeable part of human body is face. The obvious boundaries on the skin known as Pigmentary Demarcation Lines (PDL) found over face and have clear borders of abrupt transition between more hyper-pigmented skin and areas of normal skin pigmentation due to differences in melanocyte distribution that may be influenced by multiple factors. Facial pigmentary demarcation lines (PDL) directly reflect on patient’s physical appearance and self-image as they may contribute to dysmorphism and even central to depressive illness in susceptible individuals posing cosmetic concern for the patient and a challenge for dermatologist. Therefore, it is important for early …

Bioelectrics Publications

In recent years, the emerging technology of cold atmospheric pressure plasma (CAP) has grown rapidly along with the many medical applications of cold plasma (e.g., cancer, skin disease, tissue repair, etc.). Plasma-activated liquids (e.g., culture media, water, or normal saline, previously exposed to plasma) are being studied as cancer treatments, and due to their advantages, many researchers prefer plasma-activated liquids as an alternative to CAP in the treatment of cancer. In this study, we showed that plasma-activated-saline (PAS) treatment significantly inhibited tumor growth, as compared with saline, in melanoma, and a low-pH environment had little effect on tumor growth in …

It is important to understand the common presentation, complications, and ideal management of patients with necrotizing fasciitis.

Granuloma Annulare: An Updated Review Of Epidemiology, Pathogenesis, And Treatment Options, Tejas P Joshi, Madeleine Duvic

Faculty, Staff and Student Publications

Granuloma annulare (GA) is an inflammatory granulomatous skin disease that can be localized (localized GA) or disseminated (generalized GA), with patch, perforating, and subcutaneous subtypes being less common variants of this benign condition. Recently, new research has emerged that further elucidates GA epidemiology and etiopathogenesis; importantly, new therapeutic options for GA have also been described, although there remains a paucity of randomized controlled studies. In this review, we summarize recent updates on GA epidemiology and etiopathogenesis and offer an updated review of the therapeutic options for GA currently reported in the literature. We hope that the current review galvanizes randomized …

Real-World Evidence Of An Emollient Device For Atopic And Contact Dermatitis In Pediatric To Adult Patients – Data From A Post-Marketing Surveillance, Adelaide Ann Hebert

Faculty, Staff and Student Publications

PURPOSE: Atopic and contact dermatitis have been attributed to skin barrier abnormalities, immune system dysfunction and inflammation leading to pruritus. As these factors may involve oxidative stress, emollient devices containing antioxidants furfuryl palmitate and tocopherol may help reduce itching and inflammation. In this study, a post-marketing questionnaire was carried out of 40 users of a novel emollient device containing furfuryl palmitate and tocopherol (Relizema™ cream), who purchased it from a pharmacy or health-care professional to ascertain the emollient device's action on itching, flushing and moisturizing.

PATIENTS AND METHODS: The post-marketing questionnaire, administered by trained pharmacy and health-care staff, collected data …

Erythema Multiforme After Third Covid-19 Vaccination (Pfizer-Biontech), Sonali Batta, Austinn C Miller, Susuana Adjei, Laurie A Temiz, Stephen K Tyring

Faculty, Staff and Student Publications

We present a case of erythema multiforme (EM) associated with a third (booster) dose of COVID-19 vaccination in a patient who had no cutaneous reactions to previous doses. To our knowledge, this is the first documented case of vaccine-associated EM occurring after a third/booster vaccination. Furthermore, our case emphasizes the need to remain vigilant for vaccine-associated EM in any patient recently vaccinated, regardless of whether previous vaccinations were administered without cutaneous reactions.

Diagnosis And Interpretation Of Testing For Cat Scratch Disease, Nasim Khalfe, Doris Lin

Faculty, Staff and Students Publications

Cat scratch disease (CSD) is an infectious disease caused by Bartonella henselae that presents as regional lymphadenopathy which can appear within weeks after a cat scratch. There is no gold standard for diagnosis. Rather, clinicians rely on an amalgam of criteria to make a definitive diagnosis. We describe a case of a 44-year-old woman with six cats who presented with a painful left inguinal mass, had splenic lesions on imaging, and had positive serology but a negative polymerase chain reaction test for B. henselae.

Squamous Cell Carcinoma Arising In An Epidermal Inclusion Cyst, Suzanne Alkul, Christopher N Nguyen, Nisha S Ramani, Mahmud Alkul, Ida Orengo, Ikue Shimizu, Bhuvaneswari Krishnan

Faculty, Staff and Students Publications

Squamous cell carcinoma (SCC) arising from an epidermal inclusion cyst (EIC) is uncommon. We present a case of a 70-year-old man with a scalp nodule with persistent discharge that was resected based on the clinical impression of an EIC. Histopathologic exam showed an infundibular EIC with an epidermal type of squamous epithelium; however, some of the cyst lining and lumen was replaced by squamous proliferation with malignant features. There are 56 cases of SCC arising in EICs reported in the English literature. Though suspected EICs are commonly benign, a thorough pathologic evaluation is required to rule out malignancy.
