In Vivo Bioluminescence Imaging To Evaluate Systemic And Topical Antibiotics Against Community-Acquired Methicillin-Resistant Staphylococcus Aureus-Infected Skin Wounds In Mice, Yi Guo, Romela Irene Ramos, John S. Cho, Niles P. Donegan, Ambrose L. Cheung, Lloyd S. Miller

Dartmouth Scholarship

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) frequently causes skin and soft tissue infections, including impetigo, cellulitis, folliculitis, and infected wounds and ulcers. Uncomplicated CA-MRSA skin infections are typically managed in an outpatient setting with oral and topical antibiotics and/or incision and drainage, whereas complicated skin infections often require hospitalization, intravenous antibiotics, and sometimes surgery. The aim of this study was to devel

Evaluation Of Matricellular Proteins As Potential Therapeutics For The Treatment Of Human Chronic Skin Wounds, Christopher G. Elliott

Electronic Thesis and Dissertation Repository

There is currently an unmet need for treatments to enhance healing of human chronic skin wounds. Previously, therapy development has focused on growth factors and physical matrices, often resulting in disappointing clinical outcomes. In this thesis, we approached chronic skin wound treatment with a focus on fibrosis and matricellular proteins. Fibrosis is a pathological condition where tissue repair continues, unchecked, resulting in excess contraction, matrix accumulation and fibrogenic growth factor activity; features critically reduced in chronic skin wounds. Identifying factors that promote fibrosis may offer new therapeutic targets for use in chronic skin wounds. Two such factors are the matricellular …

Raman Spectroscopic Analysis Of Human Skin Tissue Sections Ex-Vivo: Evaluation Of The Effects Of Tissue Processing And Dewaxing, Syed Mehmood Ali, Franck Bonnier, Ali Tfayli, Helen Lambkin, Kathleen Flynn, Vincent Mcdonagh, Claragh Healy, Thomas Lee, Fiona Lyng, Hugh Byrne

Raman spectroscopy coupled with K-means clustering analysis (KMCA) is employed to elucidate the biochemical structure of human skin tissue sections, and the effects of tissue processing. Both hand and thigh sections of human cadavers were analysed in their unprocessed and formalin fixed paraffin processed (FFPP) and subsequently dewaxed forms. In unprocessed sections, KMCA reveals clear differentiation of the stratum corneum, intermediate underlying epithelium and dermal layers for sections from both anatomical sites. The stratum corneum is seen to be relatively rich in lipidic content; the spectrum of the subjacent layers is strongly influenced by the presence of melanin, while that …

Preventing Skin Cancer In Adolescent Girls Through Intervention With Their Mothers, Mary K. Baker

Electronic Theses and Dissertations

Indoor tanning (IT) before the age of 35 increases one’s risk for melanoma by 75%, and epidemiological data show a 6.1% annual increase in the incidence of melanomas in white women younger than age 44 in the US. Population-based studies reveal that 15% of adolescents and 8% to 14% of their primary caregivers have engaged in IT in the past year.

The compelling case for IT being a significant risk factor for melanoma, together with the high rates of IT in teen girls and their mothers, provided a strong rationale for conducting an antitanning intervention directed at mother-daughter dyads. This …

Characterization Of Differentiation And Prognostic Biomarkers On Cd8+ Tumor-Infiltrating Lymphocytes In Metastatic Melanoma, Richard C. Wu

Dissertations & Theses (Open Access)

CD8⁺ cytotoxic T lymphocytes (CTL) frequently infiltrate tumors, yet most melanoma patients fail to undergo tumor regression. We studied the differentiation of the CD8⁺ tumor-infiltrating lymphocytes (TIL) from 44 metastatic melanoma patients using known T-cell differentiation markers. We also compared CD8⁺ TIL against the T cells from matched melanoma patients’ peripheral blood. We discovered a novel subset of CD8⁺ TIL co-expressing early-differentiation markers, CD27, CD28, and a late/senescent CTL differentiation marker, CD57. This CD8⁺CD57⁺ TIL expressed a cytolytic enzyme, granzyme B (GB), yet did not express another cytolytic pore-forming molecule, perforin (Perf). In …

Are Epidermal Barrier Defects Responsible For The Underlying Pathology Of Atopic Dermatitis?, Naomi Davis

The Science Journal of the Lander College of Arts and Sciences

Atopic dermatitis, often referred to as eczema, is a chronic inflammatory skin condition frequently seen in young children. It is a complex disease involving environmental factors, genetics and immune dysregulation. There is currently no cure with conflicting opinions from physicians regarding treatment and management. A clearer understanding of pathogenesis of atopic dermatitis can hopefully lead to new and improved treatment options for patients. Current evidence seems to support epidermal skin barrier defects as the cause of this disease. This paper seeks to investigate if this out-in hypothesis can be responsible as the sole pathogenesis of atopic dermatitis. To write this …

Is Dapsone Gel Safe And Effective For The Treatment Of Acne Vulgaris?, Amy Patel

PCOM Physician Assistant Studies Student Scholarship

OBJECTIVE: The objective of this selective EBM review is to determine whether or not dapsone gel is safe and effective for the treatment of acne vulgaris.

STUDY DESIGN: A review of three English language studies published in 2007. Includes two randomized, double-blind, controlled trials and one open label, noncomparative study. DATA SOURCES: Randomized, controlled trials comparing dapsone gel to vehicle gel control were found using PubMed and Cochrane database.

OUTCOMES MEASURED: Success on the Global Acne Assessment Score (GAAS) and reduction in acne lesion counts

RESULTS: The two randomized, controlled trials and the open-label noncomparative study …

Skin Cancer - Education And Prevention: The Role Of Social Marketing, Tim Crowley

Theses

Skin cancer is the most common cancer in Ireland and worldwide. Skin cancer rates have been steadily rising in recent times. The high use of sunbeds in both Ireland and the UK is quite worrisome. Skin cancer is caused by over exposure to UV rays or through the use of sunbeds and as a result it is actually a highly preventable disease. It is estimated that 90-95% of all skin cancers are preventable. This thesis focuses on the use of social marketing in order to educate people on the dangers of skin cancer with the eventual aim of making recommendations …
