BACKGROUND The assessment of the severity of psoriasis is often subjective because of the lack of quantitative laboratory diagnostic tools. Histopathological examination is the most commonly performed procedure for psoriasis diagnosis; however, it is usually descriptive. Thus, there is currently no quantitative method of determining psoriasis severity. The(More)
BACKGROUND Despite several recent reports on the efficacy of long-pulse pulsed dye laser (LP-PDL) in treating infantile hemangiomas, controversy remains. OBJECTIVES To determine the beneficial effects of early therapeutic intervention with LP-PDL in superficial and mixed hemangiomas. METHODS AND MATERIALS Clinical data from 40 children with 47(More)
A variety of methods to prepare nanoparticle suspensions have been employed for aquatic toxicity tests, although they can influence the dispersion property and subsequent toxicity of nanoparticles. Thus, in this study, we prepared stock suspensions of silver (Ag) and copper oxide (CuO) nanoparticles using different methods and compared their acute toxicity(More)

Spontaneous regression of malignant tumors is rare especially of lung tumor and biological mechanism of such remission has not been addressed. We report the case of a 79-year-old Korean patient with non-small cell lung cancer, squamous cell cancer with a right hilar tumor and multiple lymph nodes, lung to lung metastasis that spontaneously regressed without(More)
Pigmentation is induced by production of melanin in specialized organelles termed melanosomes and by transfer of these organelles from melanocytes to surrounding keratinocytes. The chemical basis of melanogenesis is relatively well known but the mechanism of melanosome transfer is not well studied. Various pigmentary disorders and cosmetic applications(More)
Epidemiological study of Langerhans cell histiocytosis (LCH) has been limited due to its rarity and multisystemic involvement. The aim of this study was to investigate the epidemiological features of LCH via the clinical data warehouse (CDW). Clinical data of 30 LCH patients from the all departments of a tertiary referral hospital between 2003 and 2012 were(More)
