A Review Of The Efficacy Of Popular Eye Cream Ingredients, Hanin Hamie, Reem Yassine, Rajaa Shoukfeh, Dilara Turk, Farhan Huq, Meena Moossavi

Medical Student Research Symposium

Every year, there are new products on the market advertised to preserve a youthful appearance and reduce the signs of aging. One classic example is eye cream. Due to the periorbital region’s high susceptibility to damage from external factors, along with its tendency to demonstrate early signs of aging, periorbital skin is a common target for anti-aging therapy. While some of these ingredients have proven efficacious in clinical trials, others have not shown to be clinically significant. Various products contain different combinations, formulations, and doses of these ingredients. This review evaluates the efficacy of popular topical ingredients found in common …

Melanoma frequently harbors genetic alterations in key molecules leading to the aberrant activation of PI3K and its downstream pathways. Although the role of PI3K/AKT/mTOR in melanoma progression and drug resistance is well documented, targeting the PI3K/AKT/mTOR pathway showed less efficiency in clinical trials than might have been expected, since the suppression of the PI3K/mTOR signaling pathway-induced feedback loops is mostly associated with the activation of compensatory pathways such as MAPK/MEK/ERK. Consequently, the development of intrinsic and acquired resistance can occur. As a solid tumor, melanoma is notorious for its heterogeneity. This can be expressed in the form of genetically divergent …

Melanoma is the third most common type of skin cancer, characterized by its heterogeneity and propensity to metastasize to distant organs. Melanoma is a heterogeneous tumor, composed of genetically divergent subpopulations, including a small fraction of melanoma-initiating cancer stem-like cells (CSCs) and many non-cancer stem cells (non-CSCs). CSCs are characterized by their unique surface proteins associated with aberrant signaling pathways with a causal or consequential relationship with tumor progression, drug resistance, and recurrence. Melanomas also harbor significant alterations in functional genes (BRAF, CDKN2A, NRAS, TP53, and NF1). Of these, the most common are the BRAF and NRAS oncogenes, with 50% …

Hidradenitis Suppurativa Disease Severity And Outcomes Among Black Patients From Low-Income Neighborhoods At A Tertiary Care Hospital: A Retrospective Review, Anna M. Catinis, Olivia A. Gioe, Caroline Savoie, Erika Rosen, Deborah Hilton

School of Medicine Faculty Publications

Hidradenitis suppurativa (HS) is a debilitating, inflammatory condition of apocrine sweat glands. Black patients are disproportionately affected, a finding largely attributed to lower socioeconomic status (SES) in the literature; yet, most HS studies include majority White cohorts. We present, to our knowledge, the first retrospective review of an entirely Black patient population living in low-income neighborhoods diagnosed with hidradenitis suppurativa (HS) to identify potentially modifiable factors related to disease severity and outcomes. We reviewed charts of Black patients with an encounter for HS from 2010-2020 in the New Orleans University Medical Center database. Hurley stage III (HSt III) disease was …

Chlormethine Gel In Combination With Other Therapies For Treatment Of Mycosis Fungoides: A Review With Patient Cases, Marco Ardigò, Neda Nikbakht, Miriam Teoli, Laura Gleason, Liliana Crisan, Christiane Querfeld

Department of Dermatology and Cutaneous Biology Faculty Papers

Topical chlormethine gel has been approved as monotherapy for treatment of adult patients with mycosis fungoides (MF), the most common form of cutaneous T-cell lymphoma. In clinical practice, chlormethine gel is often combined with other skin-directed or systemic therapies to optimize response and target recalcitrant lesions. Positive outcomes with combination regimens using chlormethine gel and topical corticosteroids, phototherapy, retinoids, methotrexate, or interferon-α have been reported in literature. However, there are no treatment guidelines on the use of combination regimens with chlormethine gel. To provide real-world evidence and guidance on the use of chlormethine gel combination regimens, several cases of patients …

School of Medicine Faculty Publications

Third-degree burn injuries pose a significant health threat. Safer, easier-to-use, and more effective techniques are urgently needed for their treatment. We hypothesized that covalently bonded conjugates of fatty acids and tripeptides can form wound-compatible hydrogels that can accelerate healing. We first designed conjugated structures as fatty acid–aminoacid1–amonoacid2–aspartate amphiphiles (Cn acid–AA1–AA2–D), which were potentially capable of self-assembling into hydrogels according to the structure and properties of each moiety. We then generated 14 novel conjugates based on this design by using two Fmoc/tBu solid-phase peptide synthesis techniques; we verified their structures and purities through liquid chromatography with tandem mass spectrometry and nuclear …

Immunosequencing Applications In Cutaneous T-Cell Lymphoma, Jenna Mandel, Laura Gleason, Daniel Joffe, Safiyyah Bhatti, Neda Nikbakht Dec 2023

Immunosequencing Applications In Cutaneous T-Cell Lymphoma, Jenna Mandel, Laura Gleason, Daniel Joffe, Safiyyah Bhatti, Neda Nikbakht

Department of Dermatology and Cutaneous Biology Faculty Papers

Immunosequencing has emerged as a newer clinical test for assessment of T-cell clonality in the blood and skin of cutaneous T-cell lymphoma (CTCL) patients. Utilization of immunosequencing, also known as high-throughput sequencing of the T-cell receptor (HTS-TCR), enables identification and quantification of the precise genetic signature of dominant T-cell clones. Although immunosequencing is more sensitive than commonly used methods such as polymerase chain reaction (PCR) paired with capillary electrophoresis or flow cytometry, it remains underutilized for CTCL management. Nonetheless, incorporation of HTS-TCR in clinical practice offers distinct advantages compared to other molecular analyses that may improve diagnostic evaluation, prognostication, and …

Utility Of T-Cell Immunosequencing In Distinguishing Mycosis Fungoides Progression From Treatment Related Cutaneous Adverse Events, Safiyyah Bhatti, Daniel Joffe, Lauren Banner, Sahithi Talasila, Jenna Mandel, Jason Lee, Pierluigi Porcu, Neda Nikbakht

Department of Dermatology and Cutaneous Biology Faculty Papers

Cutaneous adverse events of both topical and systemic drugs in patients with mycosis fungoides (MF) present a diagnostic challenge as it is often difficult to distinguish drug associated rash from disease progression in the skin. Mogamulizumab and mechlorethamine gel are approved treatments for MF, both of which can cause treatment related cutaneous adverse events. It can often be challenging to distinguish mogamulizumab associated rash (MAR) and mechlorethamine gel associated hypersensitivity dermatitis from MF progression both clinically and histologically. High-throughput sequencing (HTS) of the T-cell receptor (TCR), also known as immunosequencing, can be used to assess T-cell clonality to support a …

INTRODUCTION: The clinical benefit of the anti-CTLA-4 monoclonal antibody (mAb) ipilimumab has been well established but limited by immune-related adverse events, especially when ipilimumab is used in combination with anti-PD-(L)1 mAb therapy. To overcome these limitations, we have developed XTX101, a tumor-activated, Fc-enhanced anti-CTLA-4 mAb.

METHODS: XTX101 consists of an anti-human CTLA-4 mAb covalently linked to masking peptides that block the complementarity-determining regions, thereby minimizing the mAb binding to CTLA-4. The masking peptides are designed to be released by proteases that are typically dysregulated within the tumor microenvironment (TME), resulting in activation of XTX101 intratumorally. Mutations within the Fc region …

Student Papers, Posters & Projects

An intact barrier function of the skin is important in maintaining skin health. The regulation of the skin barrier depends on a multitude of molecular and immunological signaling pathways. By examining the regulation of a healthy skin barrier, including maintenance of the acid mantle and appropriate levels of ceramides, dermatologists can better formulate solutions to address issues that are related to a disrupted skin barrier. Conversely, by understanding specific skin barrier disruptions that are associated with specific conditions, such as atopic dermatitis or psoriasis, the development of new compounds could target signaling pathways to provide more effective relief for patients. …

Stem cells (SCs) are critical to maintain tissue homeostasis. However, it is currently not known whether signaling through cell junctions protects quiescent epithelial SC reservoirs from depletion during disease-inflicted damage. Using the autoimmune model disease pemphigus vulgaris (PV), this study reveals an unprecedented role for a desmosomal cadherin in governing SC quiescence and regeneration through adhesion signaling in the multipotent mouse hair follicle compartment known as the bulge. Autoantibody-mediated, mechanical uncoupling of desmoglein (Dsg) 3 transadhesion activates quiescent bulge SC which lose their multipotency and stemness, become actively cycling, and finally delaminate from their epithelial niche. This then initiates a …

Student Papers, Posters & Projects

Dermatology programs in resource-limited settings manage high patient volumes.1 Trainees have extensive clinical responsibilities, which may preclude engaging in research. Programs in such settings may lack the infrastructure to provide adequate support. At the Department of Dermatovenereology at the University of Gondar in Ethiopia, residents anecdotally report a high caseload and lack of resources, including time, to pursue research. Members of Emory and Mount Sinai Dermatology designed and delivered a 30-minute presentation about research design and methods. Residents were surveyed pre- and postintervention about their attitudes toward pursuing dermatology research during residency

Distinguishing Dystrophic Calcification From Calciphylaxis, Elizabeth Jones, Alexander Valiga, Miriam Solowey Oct 2023

Distinguishing Dystrophic Calcification From Calciphylaxis, Elizabeth Jones, Alexander Valiga, Miriam Solowey

Department of Dermatology and Cutaneous Biology Faculty Papers

Introduction

Calcinosis cutis, a disorder in which calcium salts deposit in skin and subcutis, is categorized into five subtypes: dystrophic calcification, metastatic calcification, idiopathic calcification, iatrogenic calcification, and calciphylaxis.

Dystrophic calcification, the most common subtype, typically results from local tissue damage1,2 and is proposed to be caused by the release of phosphate binding proteins by necrotic cells in response to tissue damage, inflammation, or hypoxia.2 The condition often presents with nontender nodules of the skin or subcutis and normal serum calcium.

Calciphylaxis is believed to be caused by impaired inhibition of calcification in the microvasculature.3 …

An Unusual Presentation Of Pigmented Purpuric Lichenoid Dermatitis, Christine De Antonis, Jordan T. Hyde, Jason B. Lee, Sylvia Hsu

Department of Dermatology and Cutaneous Biology Faculty Papers

Pigmented purpuric lichenoid dermatitis (PPLD) is a rare subtype of pigmented purpuric dermatosis, which classically presents with a mixture of lichenoid papules and patches on the bilateral lower extremities. Herein, we describe an unusual case of a 47-year-old man with PPLD who presented with 1-3mm discrete papules without the presence of larger patches. The diagnosis of PPLD should be considered for patients presenting with bilateral symmetric discrete papules on the legs.

Brown, Haaris Mir, George Singer, Alfredo Cordova, Lisa Rae, Theresa Chin, Lourdes Castanon, Derek Bell, William Hughes, Joseph A. Molnar

Department of Surgery Faculty Papers

BACKGROUND: Traumatic insults, infection, and surgical procedures can leave skin defects that are not amenable to primary closure. Split-thickness skin grafting (STSG) is frequently used to achieve closure of these wounds. Although effective, STSG can be associated with donor site morbidity, compounding the burden of illness in patients undergoing soft tissue reconstruction procedures. With an expansion ratio of 1:80, autologous skin cell suspension (ASCS) has been demonstrated to significantly decrease donor skin requirements compared with traditional STSG in burn injuries. We hypothesized that the clinical performance of ASCS would be similar for soft tissue reconstruction of nonburn wounds.

METHODS: A …

Department of Dermatology and Cutaneous Biology Faculty Papers

INTRODUCTION: Neutrophilic panniculitis (NP) is a rare subtype of neutrophilic dermatosis, a group of neutrophil-rich inflammatory skin disorders that can present in association with myeloid neoplasms. NP is defined by the presence of a neutrophilic infiltrate in the fat lobules of the subcutis in the absence of either infection or vasculitis. We herein describe a 65-year-old woman with a recent diagnosis of myelodysplastic syndrome/myeloproliferative neoplasm overlap syndrome (MDS/MPN) who abruptly developed painful, pruritic nodules consistent with NP.

CASE PRESENTATION: A 65-year-old woman with MDS/MPN presented for evaluation of painful and pruritic nodules on her upper and lower extremities. A biopsy …


Atmospheric Pressure Plasma Treatment Of Skin: Penetration Into Hair Follicles, Kseniia Konina, Theresa A. Freeman, Mark J. Kushner Aug 2023

Atmospheric Pressure Plasma Treatment Of Skin: Penetration Into Hair Follicles, Kseniia Konina, Theresa A. Freeman, Mark J. Kushner

Department of Orthopaedic Surgery Faculty Papers

Sterilization of skin prior to surgery is challenged by the reservoir of bacteria that resides in hair follicles. Atmospheric pressure plasma jets (APPJs) have been proposed as a method to treat and deactivate these bacteria as atmospheric plasmas are able to penetrate into structures and crevices with dimensions similar to those found in hair follicles. In this paper, we discuss results from a computational investigation of an APPJ sustained in helium flowing into ambient air, and incident onto a layered dielectric similar to human skin in which there are idealized hair follicles. We found that, depending on the location of …

Leser-Trélat Sign As A Marker For Underlying Pancreatic Cancer, Kalpit Modi, Richard Chen, Layla Abubshait Aug 2023

Leser-Trélat Sign As A Marker For Underlying Pancreatic Cancer, Kalpit Modi, Richard Chen, Layla Abubshait

Einstein Health Papers

Case Presentation: Early diagnosis and rapid treatment of cancer is essential for good clinical outcomes for patients. In this case, an 85-year-old man presented with failure to thrive and was noted to have rapid-onset, multiple seborrheic keratoses (Leser-Trélat sign) on his chest and back. He was ultimately diagnosed with pancreatic cancer using computed tomography.

Discussion: Leser-Trélat sign is a rare cutaneous marker for underlying malignancy. Identification of this sign can help guide diagnostic imaging and lab work to identify an occult internal malignancy, resulting in more rapid diagnosis, earlier treatment, and potentially better clinical outcomes.


Application Of Teaching Regarding Injury Appearance In Darker Pigmented Skin Patients: A Quality Improvement Project, Tiffany Akiba Aug 2023

Application Of Teaching Regarding Injury Appearance In Darker Pigmented Skin Patients: A Quality Improvement Project, Tiffany Akiba

DNP Projects

Significance and Background: The skin is the largest organ of our body, and skin injury prevention begins with accurately inspecting skin. Current practices stress on looking for any signs of redness which often signify that the skin is possibly injured or compromised. However, darker skin tones do not appear red when injured. Assessing for redness is a practice that is suited better for lighter skin tones.

Purpose: Provide education to providers on current skin assessment practices of darker skin tones.

Methods: The IHI Model of Improvement was used for this project, and the Plan-Do-Study-Act cycle was used to test for …

Understanding The Factors Associated With Us Dermatology Resident Trainees’ Diagnostic Confidence And Skill For Skin Of Color Pathology, Alissa Jeanfreau, Kaylin Beiter, Deborah Hilton

School of Medicine Faculty Publications

Background: Inequities in dermatologic health outcomes translate to worsened clinical outcomes for minority groups. For example, despite a lower incidence of skin cancer overall, African Americans are diagnosed at later stages with greater degrees of lymph node involvement. This has been shown to lead to disproportionate mortality when compared to lighter skinned individuals. Medical education materials contain a significantly lower percentage of skin of color (SOC) images than of lighter skin and research has indicated lower diagnostic accuracy of dermatologic conditions in darker skin by U.S. medical students. The objective of this study was to explore U.S. resident dermatologists’ ability …

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Phospholipase-associated neurodegeneration (PLAN) caused by mutations in the PLA2G6 gene is a rare neurodegenerative disorder that presents with four sub-groups. Infantile neuroaxonal dystrophy (INAD) and PLA2G6-related dystonia-parkinsonism are the main two subtypes. In this cohort, we reviewed clinical, imaging, and genetic features of 25 adult and pediatric patients harboring variants in the PLA2G6.

METHODS: An extensive review of the patients' data was carried out. Infantile Neuroaxonal Dystrophy Rating Scale (INAD-RS) was used for evaluating the severity and progression of INAD patients. Whole-exome sequencing was used to determine the disease's underlying etiology followed by co-segregation analysis using Sanger sequencing. In …

Kinetics Of Wound Development And Healing Suggests A Skin-Stabilizing Effect Of Allogeneic Abcb5+ Mesenchymal Stromal Cell Treatment In Recessive Dystrophic Epidermolysis Bullosa, Elke Niebergall-Roth, Kathrin Dieter, Cristina Daniele, Silvia Fluhr, Maria Khokhrina, Ines Silva, Christoph Ganss, Markus H. Frank, Mark A. Kluth

Research outputs 2022 to 2026

Recessive dystrophic epidermolysis (RDEB) is a rare, inherited, and currently incurable skin blistering disorder characterized by cyclically recurring wounds coexisting with chronic non-healing wounds. In a recent clinical trial, three intravenous infusions of skin-derived ABCB5+ mesenchymal stromal cells (MSCs) to 14 patients with RDEB improved the healing of wounds that were present at baseline. Since in RDEB even minor mechanical forces perpetually provoke the development of new or recurrent wounds, a post-hoc analysis of patient photographs was performed to specifically assess the effects of ABCB5+ MSCs on new or recurrent wounds by evaluating 174 wounds that occurred after baseline. During …

Recalcitrant Cutaneous Mastocytosis Treated With Genetically Informed Targeted Therapy: A Case Report, Laura Gleason, Volkan Tekmen, Alexa Cohen, Safiyyah Bhatti, Burcu Beksac, Jisun Cha, Pierluigi Porcu, Neda Nikbakht

Department of Dermatology and Cutaneous Biology Faculty Papers

Introduction:

Mastocytosis, a clonal proliferation of mast cells commonly involving the skin and bone marrow, has a varied clinical presentation ranging from cutaneous lesions to systemic disease. Cutaneous mastocytosis is managed symptomatically, but systemic mastocytosis is treated with targeted therapy against the mutated receptor tyrosine kinase c-KIT, the pathogenic driver of mastocytosis. However, there are no guidelines for the treatment of cutaneous mastocytosis refractory to symptomatic management.

We herein report a method to select genetically informed therapy for symptomatic and recalcitrant cutaneous mastocytosis.

Case presentation:

We performed a mutational analysis of dermal mast cells after enrichment by laser capture in …
