  • July 2020 Goal the Goal of the Residency Program Is to Develop Future Leaders in Both Research and Clinical Medicine
    Residency Training Program July 2020 Goal The goal of the Residency Program is to develop future leaders in both research and clinical medicine. Flexibility within the program allows for the acquisition of fundamental working knowledge in all subspecialties of dermatology. All residents are taught a scholarly approach to patient care, aimed at integrating clinicopathologic observation with an understanding of the basic pathophysiologic processes of normal and abnormal skin. Penn’s Residency Program consists of conferences, seminars, clinical rotations, research, and an opportunity to participate in the teaching of medical students. An extensive introduction into the department and the William D. James, M.D. Director of Residency Program clinic/patient care service is given to first-year residents. A distinguished clinical faculty and research faculty, coupled with the clinical and laboratory facilities, provides residents with comprehensive training. An appreciation of and participation in the investigative process is an integral part of our residency. Graduates frequently earn clinical or basic science fellowship appointments at universities across the country. Examples of these include: pediatric dermatology, dermatopathology, dermatologic surgery, dermatoepidemiology, postdoctoral and Clinical Educator fellowships. Additional post graduate training has occurred at the NIH and CDC. Graduates of our program populate the faculty at Harvard, Penn, Johns Hopkins, MD Anderson, Dartmouth, Penn State, Washington University, and the Universities of Washington, Pittsburgh, Vermont, South Carolina, Massachusetts, Wisconsin, and the University of California San Francisco. Additionally, some enter private practice to become pillars of community medicine. Misha A. Rosenbach, M.D. Associate Director of Residency Program History The first medical school in America, founded in 1765, was named the College of Philadelphia.

  • Long-Lasting Muscle Thinning Induced by Infrared Irradiation Specialized with Wavelengths and Contact Cooling: a Preliminary Report
    Long-Lasting Muscle Thinning Induced by Infrared Irradiation Specialized With Wavelengths and Contact Cooling: A Preliminary Report Yohei Tanaka, MD, Kiyoshi Matsuo, MD, PhD, and Shunsuke Yuzuriha, MD, PhD Department of Plastic and Reconstructive Surgery, Shinshu University School of Medicine, Matsumoto, Nagano 390-8621, Japan Correspondence: [email protected] Published May 28, 2010 Objective: Infrared (IR) irradiation specialized with wavelengths and contact cooling increases the amount of water in the dermis to protect the subcutaneous tissues against IR damage; thus, it is applied to smooth forehead wrinkles. However, this treatment consistently induces brow ptosis. Therefore, we investigated whether IR irradiation induces muscle thinning. Methods: Rat central back tissues were irradiated with the specialized IR device. Histological evaluation was performed on sagittal slices that included skin, panniculus carnosus, and deep muscles. Results: Significant reductions in panniculus carnosus thickness were observed between controls and irradiated tissues at postirradiation day 30 (P30), P60, P90, and P180; however, no reduction was observed in nonirradiated controls from days 0 to 180. No significant changes were observed in the trunk muscle over time. From day 0, dermal thickness was significantly reduced at P90 and P180; however, no difference was observed between P180 and nonirradiated controls at day 180. DNA degradation consistent with apoptosis was detected in the panniculus carnosus at P7 and P30. Conclusions: We found that IR irradiation induced long-lasting superficial muscle thinning, probably by a kind of apoptosis. The panniculus carnosus is equivalent to the superficial facial muscles of humans; thus, the changes observed here reflected those in the frontalis muscle that resulted in brow ptosis.

Anatomy of the Dog – Fully illustrated with color line diagrams, including unique three-dimensional cross-sectional anatomy, together with radiographs and ultrasound scans – Includes topographic and surface anatomy – Tabular appendices of relational and functional anatomy “A region with which I was very familiar from a surgical standpoint thus became more comprehensible. […] Showing the clinical rele- vance of anatomy in such a way is a powerful tool for stimulating students’ interest. […] In addition to putting anatomical structures into clinical perspective, the text provides a brief but effective guide to dissection.” vet vet The Veterinary Record “The present book-atlas offers the students clear illustrative mate- rial and at the same time an abbreviated textbook for anatomical study and for clinical coordinated study of applied anatomy. Therefore, it provides students with an excellent working know- ledge and understanding of the anatomy of the dog. Beyond this the illustrated text will help in reviewing and in the preparation for examinations.

  • Fundamentals of Dermatology Describing Rashes and Lesions
    Dermatology for the Non-Dermatologist May 30 – June 3, 2018 - 1 - Fundamentals of Dermatology Describing Rashes and Lesions History remains ESSENTIAL to establish diagnosis – duration, treatments, prior history of skin conditions, drug use, systemic illness, etc., etc. Historical characteristics of lesions and rashes are also key elements of the description. Painful vs. painless? Pruritic? Burning sensation? Key descriptive elements – 1- definition and morphology of the lesion, 2- location and the extent of the disease. DEFINITIONS: Atrophy: Thinning of the epidermis and/or dermis causing a shiny appearance or fine wrinkling and/or depression of the skin (common causes: steroids, sudden weight gain, “stretch marks”) Bulla: Circumscribed superficial collection of fluid below or within the epidermis > 5mm (if <5mm vesicle), may be formed by the coalescence of vesicles (blister) Burrow: A linear, “threadlike” elevation of the skin, typically a few millimeters long. (scabies) Comedo: A plugged sebaceous follicle, such as closed (whitehead) & open comedones (blackhead) in acne Crust: Dried residue of serum, blood or pus (scab) Cyst: A circumscribed, usually slightly compressible, round, walled lesion, below the epidermis, may be filled with fluid or semi-solid material (sebaceous cyst, cystic acne) Dermatitis: nonspecific term for inflammation of the skin (many possible causes); may be a specific condition, e.g. atopic dermatitis Eczema: a generic term for acute or chronic inflammatory conditions of the skin.

After defining the characteristics, then think about causes of that type of rash: CITES MVA PITA: Congenital, Infections, Tumor, Endocrinologic, Solar related, Metabolic, Vascular, Allergic, Psychiatric, Latrogenic, Trauma, Autoimmune.
