The Impact Of Patient Characteristics On Quality Of Life In Keloid Patients, Jonathan Wang, Romsin Zaya, Rachel Zachian, Mary Metkus, Neda Nikbakht

Phase 1

Introduction: Quality of life (QoL) is an important metric in assessing dermatological diseases such as keloids. This study evaluated the effects of patient characteristics on QoL in keloid patients.

Methods: This was a cross-sectional study. 36 patients presenting to the keloid clinic at TJUH were surveyed. QoL subscale scores for emotion, symptom, and function were calculated in addition to a total score for each patient using a keloid-specific questionnaire. The association between the QoL scores and patient characteristics of sex, ethnicity, as well as keloid location, duration, visibility, size, number, pain score, and pruritis score were evaluated using t-tests. …

The Prevalence Of Orally Administered Glucocorticoids, Generalized Pustular Psoriasis And Erythrodermic Psoriasis In The Treatment Of Adult Plaque Psoriasis Provided By U.S. Dermatologists, Katherine Awh, Kumar Nasham, Christian Albornoz, Steven Feldman, Anthony Albornoz

Phase 1

Introduction: Orally administered glucocorticoids (OAG) are not recommended for the management of plaque psoriasis (PsO) due to the classically feared outcomes of generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP). Given their widespread anecdotal use, we hypothesize that the use of OAG is not infrequent among US dermatologists and is rarely complicated by GPP or EP.

Methods: Anonymous electronic survey of 50 US dermatologists. Primary outcomes of interest were the prevalence of OAG in the management of PsO and the prevalence of GPP and EP in the context of OAG tapering.

Results: Overall, 9 out of 50 (18%) respondents …

Use Of Prame Immunostaining To Distinguish Melanoma In Situ From Lentigo Senilis, Hailey Olds, Sarah Utz, Darius Mehregan

Medical Student Research Symposium

PRAME (PReferentially expressed Antigen in MElanoma) is an antigen that is expressed by malignant cells in melanoma, as well as other cancers such as breast carcinoma, renal cell carcinoma, and leukemia. PRAME immunohistochemistry has proved effective in identifying malignant melanocytes in melanoma lesions, but it is unclear if it may be used to distinguish melanoma from benign melanocytic conditions, such as lentigo senilis. In particular, melanoma in situ may be confused with lentigo senilis clinically and histologically, thus PRAME immunostaining is potentially useful for differentiating these two lesions. We evaluated 31 samples of lentigo senilis, 26 of melanoma in situ, …

Uvb-Induced Microvesicle Particle Release In Human Skin In Vivo Is Diminished Following Oral Vitamin C And E Antioxidant Administration, Cameron Mcglone

Scholarship in Medicine - All Papers

An important question in photobiology asks how Ultraviolet B (UVB, 290 – 320 nm) radiation, which mostly absorbs in the outer epidermis of skin, can generate a systemic response such as immunosuppression. Previous in vitro and ex vivo studies demonstrate UVB-dependent release of bioactive molecule-containing microvesicle particles (MVPs) from keratinocytes. Furthermore, MVP release is diminished upon antioxidant administration. The purpose of this study is to examine UVB-induced MVP release and antioxidant response in vivo. In this IRB-approved study, 8 male participants with Fitzpatrick type I or II skin were treated with 1000 J/m2 UVB irradiation to a 5 by 5 …

Moderate Heat-Assisted Gene Electrotransfer As A Potential Delivery Approach For Protein Replacement Therapy Through The Skin, Chelsea Edelblute, Cathryn Mangiamele, Richard Heller

Bioelectrics Publications

Gene-based approaches for protein replacement therapies have the potential to reduce the number of administrations. Our previous work demonstrated that expression could be enhanced and/or the applied voltage reduced by preheating the tissue prior to pulse administration. In the current study, we utilized our 16-pin multi-electrode array (MEA) and incorporated nine optical fibers, connected to an infrared laser, between each set of four electrodes to heat the tissue to 43 °C. For proof of principle, a guinea pig model was used to test delivery of reporter genes. We observed that when the skin was preheated, it was possible to achieve …

Association Between Life Course Social Determinants Of Health And Metabolic Syndrome Among Female Secondary School Teachers In Johor, Mohammad Fadzly Marzuki

Student Works (2020-2029)

Metabolic syndrome, a cluster of multiple risk factors, is known to increase the risk of cardiovascular diseases, diabetes, and certain cancers. Poor health behaviours such as poor dietary intake and physical activities are known risk factors of metabolic syndrome. However, very little is known if the social determinants of health throughout the life�course are associated with metabolic syndrome. The study aimed to explore the association between life-course social determinants of health and metabolic syndrome. The cross-sectional study involved female secondary school teachers living in the state of Johor, Malaysia. The study used available data from the Clustering of Lifestyle risk …

Unravelling The Potential Applications Of Extracellular Vesicles For The Clinical Management Of Melanoma Patients, Michael Edward Clark

Theses: Doctorates and Masters

Metastatic melanoma is the third most common cancer in Australia with global incidence increasing. After decades without effective systemic treatments for advanced melanoma, the advent of targeted and immune therapies has substantially improved patient survival. While this is encouraging, further research is needed as the majority of patients treated with targeted therapy ultimately develop drug resistance. Immunotherapy can achieve durable responses in many patients however, not all patients respond to current single or a combination of immune checkpoint inhibitors. Considering the cost and potential toxicities to patients being treated with these therapies, there is an urgent need to develop biomarkers …

Electrical and Computer Engineering Faculty Research & Creative Works

Background: Cervical intraepithelial neoplasia (CIN) is regarded as a potential precancerous state of the uterine cervix. Timely and appropriate early treatment of CIN can help reduce cervical cancer mortality. Accurate estimation of CIN grade correlated with human papillomavirus type, which is the primary cause of the disease, helps determine the patient's risk for developing the disease. Colposcopy is used to select women for biopsy. Expert pathologists examine the biopsied cervical epithelial tissue under a microscope. The examination can take a long time and is prone to error and often results in high inter-and intra-observer variability in outcomes. Methodology: We propose …

Efficacy Of Platelet-Rich Plasma (Prp) Injections Vs Topical Minoxidil In Adults With Androgenetic Alopecia, Yuan-Jane Qiu

Capstone Showcase

Androgenetic alopecia is a condition mediated by androgen (specifically DHT) and genetic factors that causes hair loss and thinning of the scalp in men and women. The hairs’ anagen phase is shortened and terminal hairs transition into vellus hairs. Although this condition is considered cosmetic in nature, it has psychologically detrimental effects. There are medical treatments available to prevent further hair loss but there is currently no cure. Topical minoxidil (Rogaine) is the most commonly used medication for androgenetic alopecia that stops hair loss and, in some cases, helps hair regrowth. However, it can cause an allergic contact dermatitis, local …

Extracellular vesicles are thought to facilitate pathogen transmission from arthropods to humans and other animals. Here, we reveal that pathogen spreading from arthropods to the mammalian host is multifaceted. Extracellular vesicles from Ixodes scapularis enable tick feeding and promote infection of the mildly virulent rickettsial agent Anaplasma phagocytophilum through the SNARE proteins Vamp33 and Synaptobrevin 2 and dendritic epidermal T cells. However, extracellular vesicles from the tick Dermacentor andersoni mitigate microbial spreading caused by the lethal pathogen Francisella tularensis. Collectively, we establish that tick extracellular vesicles foster distinct outcomes of bacterial infection and assist in vector feeding by acting …

Brooke-Spiegler Syndrome: Familial Cylindromatosis, A Rare Variant Of A Rare Familial Syndrome., Harsh Patel, William Naber, Austin Cusick, Craig Oser

Ambulatory and Primary Care Articles

Brooke-Spiegler Syndrome (BSS) is a rare autosomal dominant familial disorder resulting in dermatologic neoplasms of copious nodular appendages. Here, we report a case of Familial Cylindromatosis (FC), a subtype of BSS, in a patient with the largest cylindroma of 7.4 × 5.6 × 3.8 cm on the scalp. The patient had undiagnosed cylindromas growing for 36 years at presentation; however, he did not seek out healthcare evaluation. Excision and pathologic investigation of three large masses from different body sites determined a shared phenotype of cylindromas. Subsequent evaluation of the patient's son separately, after primary patient excision, confirmed cylindroma development as …

Biofilm infections in wounds seriously delay the healing process, and methicillin-resistant Staphylococcus aureus is a major cause of wound infections. In addition to inactivating micro-organisms, low-temperature gas plasma can restore the sensitivity of pathogenic microbes to antibiotics. However, the combined treatment has not been applied to infectious diseases. In this study, low-temperature gas plasma treatment promoted the effects of different antibiotics on the reduction of S. aureus biofilms in vitro. Low-temperature gas plasma combined with rifampicin also effectively reduced the S. aureus cells in biofilms in the murine wound infection model. The blood and histochemical analysis demonstrated the biosafety of …

A Case Of Simpson-Golabi-Behmel Syndrome Presenting With Cutaneous Findings, Tessa Mullins, Abigail Russell, Chad Johnston

HCA Healthcare Journal of Medicine

Simpson-Golabi-Behmel syndrome is a rare, X-linked recessive syndrome associated with mutations in the genes encoding glypican 3 (GPC3). The majority of cases have been described in pediatric males, with those affected showing manifestations of overgrowth, congenital heart defects, and increased incidence of neoplasia. Due to the X-linked nature of this disorder, penetrance is not well understood in female cases. Very few cases of female presentations of Simpson-Golabi-Behmel syndrome have been described, and this case highlights that there may be an association between mutated GPC3 carrier status and other cancers. We present a case of GPC3 gene mutation suggestive …

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Seborrheic dermatitis (SD) is a chronic relapsing dermatitis manifesting in the seborrheic area, affecting infants or adults. In Indonesia, the prevalence of SD is 0.99–5.8% of all dermatology cases from 2013 to 2015. SD has been known to be a prominent manifestation among HIV patients, but there is an increasing trend in the general population. Therefore, in 2017, the Indonesian Society for Dermatology and Venereology proposed a consensus for the management of SD in Indonesia based on the discussion from 12 dermatological centers. Concurrent with the development of new drugs, this study aims to evaluate and develop a …

Lucio’S Phenomenon: A Report On Six Patients In A Tertiary Referral Hospital In Indonesia, Melani Marissa, Rahadi Rihatmadja, Denny Surya, Henry W. Lim, Sri Linuwih Menaldi

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Lucio's phenomenon (LP) is a rare variant of leprosy reaction, with the clinical manifestation of “necrotizing erythema.” LP was observed in patients with lepromatous leprosy who have not received or completed the treatment, and it is especially evident in patients with diffuse lepromatous leprosy (DLL), known as Lucio-Latapi’s leprosy. LP occurs due to M. leprae invading the blood vessels, causing endothelial damage that leads to thrombosis, ischemia, infarction, and tissue necrosis. The clinical features of the disease are erythematous lesions that can be accompanied by vesicles or bullae, with ulcers forming scar tissues. Histopathological examination can help establish …

Correlation Between Clinical And Histopathological Findings Of Five Puzzling Cases Of Cutaneous Tuberculosis, Eliza Miranda, Sandra Widaty, Sondang Pandjaitan Sirait, Luddwi Achmad Rizky, Sri Linuwih Menaldi, Henry W. Lim

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Cutaneous tuberculosis refers to the clinical manifestation of extrapulmonary tuberculosis affecting the skin. Determining the type of cutaneous tuberculosis from a patient afflicted with is challenging because clinical and histopathological similarities exist between types. Moreover, confirming a diagnosis of cutaneous tuberculosis is difficult because of its similarity with other diseases. For instance, typical and atypical cutaneous tuberculosis may have similar manifestations, but each disease is managed by completely different approaches. Microbiological examination with polymerase chain reaction and bacterial culture are the gold standard methods used to confirm a diagnosis of cutaneous tuberculosis. However, results often demonstrate negative findings. …

Cutaneous Candidiasis Mimicking Inverse Psoriasis Lesion In A Type 2 Diabetes Mellitus Patient, Steven Philip Surya, Kardiana Purnama Dewi, Regina Regina

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Type 2 diabetes mellitus (T2DM) condition could affect the skin. The disease is among the greatest risk factors of skin infection such as cutaneous candidiasis and is also associated with autoimmune skin diseases such as psoriasis, which lesion morphologies and predilection areas are quite similar. These similarities are a source of confusion to clinicians.

Case illustration: We present a 60-year-old female patient with uncontrolled T2DM and multiple erythematous plaques in the form of shiny lesions at the intertriginous area that developed 1 week prior to her hyperglycemic state. The lesions had recurred at the same site for …

Purpuric Lesion In A Patient With Leprosy: Was It A Lucio’S Phenomenon Or An Epiphenomenon?, Sri Linuwih Menaldi, Melani Marissa, Inadia Putri Chairista, Henry W. Lim, Rahadi Rihatmadja

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Lucio’s phenomenon (LP) is a severe necrotizing cutaneous reaction that occurs in patients with Lucio’s leprosy. The exact pathomechanism is not fully understood, but typically abundant acid-fast bacilli in the walls of blood vessels point to direct perturbation of blood supply to the epidermis. We report a case of LP where epidermal necrosis occurred in the absence of vascular invasion by mycobacteria, raising the question whether this was an epiphenomenon or a true LP.

Case Illustration: A 34-year-old male was referred for an episodic swelling of his hands and feet that persisted for two years. There were …
