Congenital Muscular Dystrophy-Associated Inflammatory Chemokines Provide Axes For Effective Recruitment Of Therapeutic Adult Stem Cell Into Muscles, Vitali Alexeev, Jacquelyn Olavarria, Paolo Bonaldo, Luciano Merlini, Olga Igoucheva

Department of Dermatology and Cutaneous Biology Faculty Papers

Background: Congenital muscular dystrophies (CMD) are a clinically and genetically heterogeneous group of neuromuscular disorders characterized by muscle weakness. The two most prevalent forms of CMD, collagen VI-related myopathies (COL6RM) and laminin α2 deficient CMD type 1A (MDC1A), are both caused by deficiency or dysfunction of extracellular matrix proteins. Previously, we showed that an intramuscular transplantation of human adipose-derived stem cells (ADSC) into the muscle of the Col6a1-/- mice results in efficient stem cell engraftment, migration, long-term survival, and continuous production of the collagen VI protein, suggesting the feasibility of the systemic cellular therapy for COL6RM. In order for this …

BACKGROUND: Poorly healing wounds are one of the major complications in patients suffering from recessive dystrophic epidermolysis bullosa (RDEB). At present, there are no effective means to analyze changes in cellular and molecular networks occurring during RDEB wound progression to predict wound outcome and design betted wound management approaches.

OBJECTIVES: To better define mechanisms influencing RDEB wound progression by evaluating changes in molecular and cellular networks.

METHODS: We developed a non-invasive approach for sampling and analysis of wound-associated constituents using wound-covering bandages. Cellular and molecular components from seventy-six samples collected from early, established and chronic RDEB wounds were evaluated by …

Purpose: This serves as a comprehensive review of the available scientific literature on the utilization of tissue adhesives compared to traditional bilayered closures. We discuss benefits, drawbacks, as well as novel surgical techniques, as applicable to dermatologic surgery.

Methods: A literature review was performed using Pubmed and MEDLINE for relevant articles related to the use of adhesives and …

Metastatic Squamous Cell Carcinoma: A Cautionary Tale, Colby Shreve, Chase Shropshire, David G. Cotter

School of Medicine Faculty Research

Cutaneous squamous cell carcinoma (cSCC) typically arises from a malignant proliferation of keratinocytes. It is the second most common cancer in the United States and typically affects older white men. Risk factors for cSCC include ultraviolet radiation exposure, light skin tone, and immunosuppression. Although metastasis in cSCC is rare, primary tumor characteristics such as location, size, and depth of invasion, among others, can help risk-stratify lesions for local recurrence, metastatic events, and death. We present a case of primary cutaneous metastatic squamous cell carcinoma masquerading as a cyst on the left temple of a 73-year-old Caucasian man following numerous treatments …

Accidental Silver Clay Tattoo: Mystery Finding In A Jewelry Smith, Tom Selby, Christina E. Borchers, Jeffery B. Travers, Samia Borchers

Dermatology Faculty Publications

Permanent tattoos result from the introduction of insoluble pigmentsinto the dermis. The mechanism can be intentional for cosmetic ormedical purposes, as with professional tattooing; or accidental asseen with carbon-related traumatic tattooing. Pigments are generallycomposed of various inorganic salts or metals. Pathology in non-inflamed tattoos will show dermal pigment granules of different sizesand shapes.1 Local inflammatory reactions can occur.Unintentional tattooing related to trauma involving asphalt, carbon,graphite, and gun powder are well known. Other cases involvingjewelry and fireworks have been reported in the literature.2,3 Similarissues arise with accidental placement of amalgam in the oralmucosa during dental procedures.4 We present an interesting caseof …

We hypothesized that human genes differ by their sensitivity to ultraviolet (UV) exposure. We used somatic mutations detected by genome-wide screens in melanoma and reported in the Catalog Of Somatic Mutations In Cancer. As a measure of UV sensitivity, we used the number of silent mutations generated by C>T transitions in pyrimidine dimers of a given transcript divided by the number of potential sites for this type of mutations in the transcript. We found that human genes varied by UV sensitivity by two orders of magnitude. We noted that the melanoma-associated tumor suppressor gene CDKN2A was among the top …

Superficial Basal Cell Carcinoma Of The Face Successfully Treated With Ingenol Mebutate 005% Gel: Case Report And A Review Of The Literature, Theodore Rosen, Kami Lowery

Faculty, Staff and Students Publications

A 64 year-old Caucasian male patient with a long history of ultraviolet light exposure and multiple actinic keratoses presented with a large, erythematous, and scaly plaque on his forehead. Biopsies revealed superficial basal cell carcinoma (sBCC). Because the patient wanted the shortest possible topical regimen, his sBCC was treated with two overnight ingenol mebutate (IM) 0.05% gel applications. He tolerated the local skin reaction (LSR) well, and at approximately six weeks post-treatment, biopsies showed no evidence of sBCC. The patient was happy with the cosmetic outcome and has remained free of clinical recurrence for 18 months. Although IM gel is …

Complex Reconstruction After Extreme Fournier’S Gangrene; A Case Report, Serban Dumitrache, Leonida A. Goman, Raluca Dutu, Raluca Capatina, Carmen Giuglea, Dan M. Enescu

Journal of Mind and Medical Sciences

In this article we present a severe case of Fournier's gangrene (FG) that affected a 64-year-old male patient, with no other known comorbidities. FG is a type of necrotizing fasciitis of the perineal and genital regions, that affects mostly males in the 5th-7th decades, with mortality rates that reach 70%. The infection usually advances through the superficial fascial layers of the perineum and abdomen and affects the skin. In our case the infection also affected the spermatic fasciae and advanced in the abdominal and pelvic cavities, abdominal muscles, and surrounding soft tissues. Subsequent debridement left the patient with large soft …

Carbamazepine-Induced Dress Syndrome: A Case Report, Andrada Luciana Lazar, Olga Hilda Orășan, Corina Baican, Nicolae Voicu Rednic, Adela Sitar-Tăut, Bogdan Man, Vasile Negrean, Nicolae Rednic, Angela Cozma

Journal of Mind and Medical Sciences

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a potentially life-threatening, idiosyncratic, acute adverse drug reaction. Fever, morbilliform cutaneous eruption, and eosinophilia are essential features for the diagnosis of this syndrome, along with significant multisystem involvement, hepatitis being the most common, followed by nephritis. The pathogenesis of DRESS syndrome is not yet fully understood. Several hypotheses have been proposed which support the involvement of an intricate interplay of multiple factors. We report a clinical case of DRESS syndrome with renal injury, induced by carbamazepine, in a patient with alcohol abstinence syndrome. In order to define the case, the …

Journal of Mind and Medical Sciences

Starting from a new organic sunscreen synthesized in our laboratory by the condensation of sodium salt of the p-aminosalicylic acid with 2,6 – dichloroacetanilide, efficient cosmetic formulation with broad photoprotective properties was obtained by using the new compound as organic UV filter, metal oxides as inorganic filters, and vegetable extracts, oils and other ingredients with emollient, protective, and moisturizing effect. After showing the lack of toxicity of the new compound, in order to reduce the amount of UV filter used, it was encapsulated into nanostructured lipid carriers (NLCs). The final cream has demonstrated good qualities for skin application, possessing suitable …

A Case Of Streptococcal Surgical Site Infection Following Mohs Surgery, Kami B Lowery, John J Kohorst, C Helen Malone, Ikue Shimizu

Faculty, Staff and Students Publications

Group A β-hemolytic Streptococcal (GAS) cellulitis is an uncommon surgical site infection that presents with rapid onset of pain and swelling in the first few days after a procedure. Unlike staphylococcal cellulitis, GAS cellulitis lacks purulence and spreading erythema. The absence of these classic signs may delay the diagnosis of GAS cellulitis and lead to severe complications. We present the case of an immunosuppressed 49-year-old patient who developed swelling and severe pain at his incision site two days after undergoing Mohs micrographic surgery on his forehead. He was clinically diagnosed with GAS cellulitis and recovered with intravenous antibiotics. Unfortunately, there …

Ier5, A Dna Damage Response Gene, Is Required For Notch-Mediated Induction Of Squamous Cell Differentiation, Li Pan, Madeleine E Lemieux, Tom Thomas, Julia M Rogers, Colin H Lipper, Winston Lee, Carl Johnson, Lynette M Sholl, Andrew P. South, Jarrod A Marto, Guillaume O Adelmant, Stephen C Blacklow, Jon C Aster

Department of Dermatology and Cutaneous Biology Faculty Papers

Notch signaling regulates squamous cell proliferation and differentiation and is frequently disrupted in squamous cell carcinomas, in which Notch is tumor suppressive. Here, we show that conditional activation of Notch in squamous cells activates a context-specific gene expression program through lineage-specific regulatory elements. Among direct Notch target genes are multiple DNA damage response genes, including IER5, which we show is required for Notch-induced differentiation of squamous carcinoma cells and TERT-immortalized keratinocytes. IER5 is epistatic to PPP2R2A, a gene that encodes the PP2A B55α subunit, which we show interacts with IER5 in cells and in purified systems. Thus, Notch and DNA-damage …

Impaired wound healing complicates a wide range of diseases and represents a major cost to healthcare systems. Here we describe the use of discarded wound dressings as a novel, cost effective, accessible, and non-invasive method of isolating viable human cells present at the site of skin wounds. By analyzing 133 discarded wound dressings from 51 patients with the inherited skin-blistering disease epidermolysis bullosa (EB), we show that large numbers of cells, often in excess of 100 million per day, continually infiltrate wound dressings. We show, that the method is able to differentiate chronic from acute wounds, identifying significant increases in …
