Acne is one of the most prevalent skin conditions seen by dermatologists. The cosmetic sequelae of severe acne, including scarring and pigmentation, have a profound psychological impact on those in icted. Topical (eg, retinoids, antibiotics, dapsone, hydroxyacids) and oral treatments (eg, antibiotics and/or spironolactone) are often bene cial to control acne or in the instance of oral isotretinoin use, rid the acne permanently; however, these treatments have very little affect on the ultimate cosmetic outcome of the acne scarring and skin texture that results...

A robotic system can select and remove individual hair follicles from the donor area with great precision and without fatigue. This report describes the use of the robotic system in a megasession for hair restoration. Patients were instructed to cut their hair to 1.0 to 1.2 mm before surgery. The robot selected and removed 600 to 800 grafts per hour so the follicular units (FU)s could be transplanted manually to recipient sites. The robot arm consists of a sharp inner punch and a blunt outer punch which together separate FUs from the sur- rounding tissue...

OBJECTIVE: Various types of wound-healing dressings have been used to assist in the healing of surgical wounds. We analyzed the wound-healing process in an animal model using different existing wound dressings. STUDY DESIGN: Full-thickness defects were created using a biopsy punch on the backs of 7-week-old rats. The wounded areas were covered with NEOVEIL (polyglycolic acid [PGA]) or TERUDERMIS (collagen sponge [CS]) affixed using a rat jacket. The wound area, neo-epithelium length, and α-smooth muscle actin (α-SMA) expression were evaluated and compared among the control, PGA, and CS groups...

Boxing is one of the most popular striking combat sports in the world. The aim of this review was to present data concerning performance analysis (time-motion and technical/tactical analysis) and physiological responses (i.e., blood lactate concentration [BLC], heart rate and/or oxygen consumption) during novice and elite male simulated and official amateur boxing competitions in any age category. The present review shows that boxing competition is a high-intensity intermittent striking combat sport. Typically, the activity-to-rest ratio was higher in elite (18:1) than novice (9:1) boxers and significant differences were observed between rounds (1 round=16:1, 2 round=8:1, and 3 round=6:1) in novice boxers...

Dermal fibroblasts secrete various growth factors which are important for skin pigmentation. Imbalance in the synchronization of epidermal and dermal cells in the skin can play vital role in the pathogenesis of pigmentary disorder vitiligo. Therefore, our objective was to check the lesional fibroblasts for any abnormality and senescence in non-segmental vitiligo patients (NSV). Skin punch biopsies were taken from NSV patients and healthy controls. Explant culture of fibroblast from lesional dermis, non-lesional dermis, and control was analyzed...

Fibroblastic connective tissue nevus (FCTN) is a rare and recently described neoplasm of fibroblastic/myofibroblastic lineage. We report a case of a 1-month-old healthy male infant who presented with a dermal plaque on the upper chest since birth. A punch biopsy demonstrated a dermal spindle-cell neoplasm with variable smooth muscle actin positivity and negative staining for CD34, consistent with myofibroma. Over the course of the next year, the remaining lesional tissue exhibited clinical softening and a surgical excisional specimen revealed histologic findings distinct from the original biopsy...

An oscillation indentation method is developed for characterizing the local poroelastic properties of soft and hydrated materials such as hydrogels and biological tissues. In the dynamic oscillation indentation measurement, an indenter is pressed into the material to a certain depth and held for a period of time. After a plateau of force is reached, an oscillation of small depth is superimposed sweeping through a range of frequencies. The shift between the force and displacement spectra is denoted as the phase lag that characterizes the energy dissipative behavior of the soft hydrated materials due to solvent migration...

Animal models of diabetic delayed wound healing are essential to the development of strategies to improve clinical approaches for human patients. The Zucker diabetic Sprague Dawley (ZDSD) rat has proved to be an accurate model of diet-induced obesity and diabetes and we evaluated the utility of the ZDSD rat as a model for delayed wound healing associated with diabetes and obesity. Groups of ZDSD and Sprague Dawley (SD) rats were placed on a diabetogenic diet and evaluated two weeks later for hyperglycemia, as a sign of diabetes...

GATA3 has been recognized as the novel marker for identifying primary and metastatic breast carcinomas, consistently showing that GATA3 was significantly more sensitive than traditional markers gross cystic disease fluid protein 15 (GCDFP15) and mammaglobin (MGB). However, clinically useful groups of breast carcinomas status were not identified, which were determining appropriate treatment strategy, affecting the prognosis. In this study, we undertook a comparative study of the marker GATA3 and GCDFP15 and MGB in clinically useful groups of paired primary and metastatic breast cancer...

Arsenic is commonly known to be associated with squamous cell carcinoma. Among the lesser known associations is basal cell carcinoma and even rarer is its effect on blood vessels causing peripheral vascular disease. Here we present a case of a 55 yr old man with ulceroproliferative lesions on scalp and forehead along with several hyperpigmented patches on trunk and extremities. He had symptoms suggestive of Raynaud's phenomenon that eventually led to digital gangrene. FNAC was done which was suggestive of basal cell carcinoma...
