Although the treatment of tinea incognito is simple and relatively easy, its clinical manifestation varies and can masquerade as various skin disorders, causing misdiagnosis and thus preventing prompt and(More)
BACKGROUND The use of ablative lasers based on the fractional approach is a novel strategy for the treatment of postoperative and acne scars in addition to wrinkles. OBJECTIVE To evaluate and compare the efficacy of carbon dioxide ablative fractional laser (AFL) and the pulsed dye laser (PDL) for the improvement of surgical scars. MATERIALS AND METHODS(More)
BACKGROUND Pigmented purpuric dermatoses (PPD) are a spectrum of disorders characterized by a distinct purpuric rash. Although PPD can be easily diagnosed, the disease entity remains an enigma and a therapeutic challenge. OBJECTIVE The purpose of this study was to investigate the characteristics and clinical manifestations of PPD and to elucidate the(More)
BACKGROUND Excess subcutaneous fat causes not only cosmetic issues, but also substantial systemic health problems. Cryolipolysis has been reported to provide non-invasive fat reduction that significantly reduces subcutaneous fat cells with controlled, localized cooling. OBJECTIVE This study is intended to determine whether a cryolipolysis device can(More)
AIM Most studies about the structures of the human skin have been on the general histologic features of the skin. The purpose of this study was to understand the relationship between the microrelief (MR) pattern and histologic structure of the human skin, and to find the usefulness of the three-dimensional reconstruction (3DR) technique of pathological skin(More)
Autologous fat injection is widely used procedure for various functional and aesthetic purposes. However, it could result in many immediate or delayed complications including dystrophic calcifications. Almost all of the case reports about dystrophic calcification after autologous fat injection were result from the iatrogenic tissue trauma of breast(More)
A new automatic target recognition (ATR) technique called Fractal Transform is presented. The fractal transform is a combination of fractal image processing and the Hough transform. A measurement of the power spectral density (PSD) of an input scene was performed using a ringwedge detector to obtain a log (PSP) vs. log (spatial frequency) plot. By analyzing(More)
BACKGROUND The rapid development of information and communication technology has replaced traditional books by electronic versions. Most print dermatology journals have been replaced with electronic journals (e-journals), which are readily used by clinicians and medical students. OBJECTIVE The objectives of this study were to determine whether e-readers(More)
