Reactive Granulomatous Dermatitis Associated With Ovarian Cancer And A Review Of Its Role As A Harbinger For Malignancy, Alexander Sherban, Jisun Cha, Elizabeth Jones

Department of Dermatology and Cutaneous Biology Faculty Papers

Reactive granulomatous dermatitis (RGD) is a rare dermatosis with a variety of cutaneous manifestations unified by a dermal granulomatous infiltrate on histology. Rheumatoid arthritis and autoimmune disease are classic associations, but an increasing number of cases have been attributed to covert malignancy. Only 41 cases of paraneoplastic RGD have been documented to our knowledge and we present an additional case that manifested eight months prior to the diagnosis of ovarian cancer and clinically mimicked morphea. Histopathologic examination identifying palisaded CD68+ cells and collagen degeneration are helpful in diagnosing this entity which may mimic a host of other cutaneous processes, including …

Oxidative Stress Induced By Reactive Oxygen Species (Ros) And Nadph Oxidase 4 (Nox4) In The Pathogenesis Of The Fibrotic Process In Systemic Sclerosis: A Promising Therapeutic Target, Sonsoles Piera-Velazquez, Sergio A. Jimenez

Department of Dermatology and Cutaneous Biology Faculty Papers

Numerous clinical and research investigations conducted during the last two decades have implicated excessive oxidative stress caused by high levels of reactive oxygen species (ROS) in the development of the severe and frequently progressive fibrotic process in Systemic Sclerosis (SSc). The role of excessive oxidative stress in SSc pathogenesis has been supported by the demonstration of increased levels of numerous biomarkers, indicative of cellular and molecular oxidative damage in serum, plasma, and other biological fluids from SSc patients, and by the demonstration of elevated production of ROS by various cell types involved in the SSc fibrotic process. However, the precise …

Collagen-Based Biomaterials With Possible Therapeutic Effects, Ramona Mihaela Nedelcuţă, Gigi Călin, Mihai Cristian Nedelcuţă, Vlad Dumitru Baleanu, Dragos Virgil Davitoiu, Bogdan Socea, Bogdan-Petre Stănoiu

Journal of Mind and Medical Sciences

Epidermolysis bullosa (EB) is a rare, serious genetic disease, incurable through the current means. Apart from this initial definition, there was later some ease in the definition of the disease, including the manifestations of toxic epidermal necrolysis and Stevens Johnson syndrome in this entity. In medical practice, there are cases that do not overlap with the description in the literature, thus the treatment must be adapted and personalized to the particularities. We present the case of a female new-born, with "de novo" mutation for the early-onset antenatal epidermolysis and our personalized therapeutic management, based on collagen from bovine corneas by …

The Role Of Photography In Increasing Efficiency Of Dermatologic Inpatient Consulting Service, Ritu Swali, Tyler D. Evans, Dillon Clarey, Corey Georgesen, Ashley Wysong

Graduate Medical Education Research Journal

Abstract

Introduction:

Inpatient dermatology consultations can bring a mixed bag of pathologies. Due to the highly specialized nature of dermatology and the lack of dermatologic training in medical school, the dermatologic team is consulted for matters that range from non-urgent to pressing. Pictures are a critical component of dermatology and greatly aid in the diagnosis of cutaneous diseases. In the inpatient setting, pictures can help streamline diagnosis and prevent unnecessary tests or procedures. The purpose of this study was to evaluate for the presence of pictures in patients’ chart after a dermatology consult had been placed through EPIC at the …

Dark Side Of Cancer Therapy: Cancer Treatment-Induced Cardiopulmonary Inflammation, Fibrosis, And Immune Modulation, Boopathi Ettickan, Chellappagounder Thangavel

Department of Dermatology and Cutaneous Biology Faculty Papers

Advancements in cancer therapy increased the cancer free survival rates and reduced the malignant related deaths. Therapeutic options for patients with thoracic cancers include surgical intervention and the application of chemotherapy with ionizing radiation. Despite these advances, cancer therapy-related cardiopulmonary dysfunction (CTRCPD) is one of the most undesirable side effects of cancer therapy and leads to limitations to cancer treatment. Chemoradiation therapy or immunotherapy promote acute and chronic cardiopulmonary damage by inducing reactive oxygen species, DNA damage, inflammation, fibrosis, deregulation of cellular immunity, cardiopulmonary failure, and non-malignant related deaths among cancer-free patients who received cancer therapy. CTRCPD is a complex …

A Review Of Fixed Drug Eruption With A Special Focus On Generalized Bullous Fixed Drug Eruption., Hannah J. Anderson, Jason B. Lee, Md

Department of Dermatology and Cutaneous Biology Faculty Papers

Fixed drug eruption (FDE) is a cutaneous adverse drug reaction characterized by the onset of rash at a fixed location on the body each time a specific medication is ingested. With each recurrence, the eruption can involve additional sites. Lesions can have overlying vesicles and/or bullae, and when they cover a significant percentage of body surface area, the eruption is referred to as generalized bullous fixed drug eruption (GBFDE). Due to the widespread skin denudation that can be seen in this condition, GBFDE may be confused clinically with Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). While treatments described for GBFDE include supportive …

A wide variety of diseases and drugs can cause cutaneous pustular eruptions. Acute generalized exanthematous pustulosis (AGEP) is a unique drug-induced dermatosis clinically presented as erythematous papular and pustular eruption, usually caused by certain systemic drugs. We are presenting a very rare association of AGEP with a biological agent, cetuximab. A male aged 66 years, who was recently diagnosed with a case of squamous cell carcinoma of glottis, presented in the dermatology clinic with a recent onset of fever and widespread pustular eruption over the face, trunk, and limbs. The eruption was noted after the injection of cetuximab given for …

Development Of The Biohybrid Assay: Combining Primary Human Vascular Smooth Muscle Cells And Blood To Measure Vascular Calcification Propensity, Armand M G Jaminon, Asim C Akbulut, Niko Rapp, Rafael Kramann, Erik A L Biessen, Lieve Temmerman, Barend Mees, Vincent Brandenburg, Robert Dzhanaev, Willi Jahnen-Dechent, Juergen Floege, Jouni Uitto, Chris P Reutelingsperger, Leon J Schurgers

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Vascular calcification is an active process that increases cardiovascular disease (CVD) risk. There is still no consensus on an appropriate biomarker for vascular calcification. We reasoned that the biomarker for vascular calcification is the collection of all blood components that can be sensed and integrated into a calcification response by human vascular smooth muscle cells (hVSMCs).

METHODS: We developed a new cell-based high-content assay, the BioHybrid assay, to measure in vitro calcification. The BioHybrid assay was compared with the o-Cresolphthalein assay and the T50 assay. Serum and plasma were derived from different cohort studies including chronic kidney disease (CKD) …

Insights Into Cutaneous Squamous Cell Carcinoma Pathogenesis And Metastasis Using A Bedside-To-Bench Approach, Marissa Lobl

Theses & Dissertations

Cutaneous squamous cell carcinoma (SCC) is the second most common skin cancer, affecting 1,000,000 people in the United States annually and causing approximately 9,000 deaths. SCC and basal cell carcinoma are the most common types of skin cancer arising in the superficial squamous cells or deeper basal cells of the epidermis, respectively. SCC is more likely to invade and metastasize, while basal cell cancer tends to grow locally. While the majority of cases of SCC are cured by surgery alone, approximately 2-5% of SCCs metastasize, at which point outcomes may be poor. Specific patient groups, particularly immunosuppressed patients, have a …

Gene Expression Profiling Of Mapk Pathway Inhibitor Resistance In Cutaneous Melanoma: Can Bioinformatics Be Used To Select Better Melanoma Cell Lines?, Stephen Luebker

Theses & Dissertations

Melanoma is the deadliest form of skin cancer, and incidence has continued to increase. Half of all melanomas have a BRAF V600E mutation and respond to MAPK pathway inhibitors, including BRAF inhibitor therapy or BRAF/MEK inhibitor combination therapy, but nearly all patients develop treatment resistance. Melanoma cell lines produce variable results as models of MAPK pathway inhibitor resistance. To better understand how the genomic similarity of a melanoma cell line to patient-derived tumors affects resistance mechanisms, differences in DNA mutations and copy-number alterations were compared between melanoma cell lines profiled by the Cancer Cell Line Encyclopedia and cutaneous melanoma tumors …

Preoperative, Multidisciplinary Clinical Optimization Of Patients With Severely Depressed Left Ventricular Ejection Fraction Who Are Undergoing Coronary Artery Bypass Grafting, Islam Mohammad Shehata, Tiffany D. Odell, Amir Elhassan, Maxim Spektor, Ivan Urits, Omar Viswanath, George M. Jeha, Elyse M. Cornett, Alan D. Kaye

School of Medicine Faculty Publications

Coronary artery bypass grafting (CABG) remains a routine operation despite major advancements in angioplastic procedures. Around 200,000 CABG procedures are performed annually in the U.S. Patients who are not candidates for angioplasty intervention often have advanced coronary disease and comorbidities that raise the risk of heart failure with decreased ejection fraction to around 25%. Over the years, significant developments in various preoperative interventions have occurred; in this paper, we suggest a multidisciplinary preoperative algorithm that can be included in a regularly scheduled multidisciplinary care plan.
