Seborrheic Dermatitis: an Overview ROBERT A
Seborrheic Dermatitis: An Overview ROBERT A. SCHWARTZ, M.D., M.P.H., CHRISTOPHER A. JANUSZ, M.D., and CAMILA K. JANNIGER, M.D. University of Medicine and Dentistry at New Jersey-New Jersey Medical School, Newark, New Jersey Seborrheic dermatitis affects the scalp, central face, and anterior chest. In adolescents and adults, it often presents as scalp scaling (dandruff). Seborrheic dermatitis also may cause mild to marked erythema of the nasolabial fold, often with scaling. Stress can cause flare-ups. The scales are greasy, not dry, as commonly thought. An uncommon generalized form in infants may be linked to immunodeficiencies. Topical therapy primarily consists of antifungal agents and low-potency steroids. New topical calcineurin inhibitors (immunomodulators) sometimes are administered. (Am Fam Physician 2006;74:125-30.

Pompholyx Factsheet Pompholyx Eczema (Also Known As Dyshidrotic Eczema/Dermatitis) Is a Type of Eczema That Usually Affects the Hands and Feet
12 Pompholyx factsheet Pompholyx eczema (also known as dyshidrotic eczema/dermatitis) is a type of eczema that usually affects the hands and feet. In most cases, pompholyx eczema involves the development of intensely itchy, watery blisters, mostly affecting the sides of the fingers, the palms of the hands and soles of the feet. Some people have pompholyx eczema on their hands and/or feet with other types of eczema elsewhere on the body. This condition can occur at any age but is usually seen in adults under 40, and is more common in women. The skin is initially very itchy with a burning sensation of heat and prickling in the palms and/or soles. Then comes a sudden crop of small blisters (vesicles), which turn into bigger weepy blisters, which can become infected, causing redness, pain, swelling and pustules. There is often subsequent peeling as the skin dries out, and then the skin can become red and dry with painful cracks (skin fissures). Pompholyx eczema can also affect the nail folds and skin around the nails, causing swelling (paronychia). What causes it? A reaction could be the result of contact with potential irritants such as soap, detergents, solvents, acids/alkalis, The exact causes of pompholyx eczema are not known, chemicals and soil, causing irritant contact dermatitis. Or although it is thought that factors such as stress, there could be an allergic reaction to a substance that is sensitivity to metal compounds (such as nickel, cobalt or not commonly regarded as an irritant, such as rubber or chromate), heat and sweating can aggravate this nickel, causing allergic contact dermatitis. -

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. -

The properties of PNIPAAm-CNC hybrid hydrogels were dependent on the amounts of incorporated CNC. The thermal stability of the hydrogels decreased with increasing CNC content. The rheological measurement indicated that the elastic and viscous moduli of hydrogels increased with the higher amounts of CNC addition, representing stronger mechanical properties of the hydrogels. Moreover, the hydrogel injection also supported the hypothesis that CNC reinforced the hydrogels; the increased CNC content exhibited higher structural integrity upon injection. The PNIPAAm- CNC hybrid hydrogels exhibited clear thermo-responsive behavior; the volume phase transition temperature (VPTT) was in the range of 36 to 39 °C, which is close to normal human body temperature. -
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.
