The low-fluence 1064-nm Q-switched neodymium:yttrium-aluminium-garnet (QSNY) laser is a widely used treatment for melasma in East Asia, although its mechanism of action is unclear. The aim of this study was to elucidate the mechanism of action of the QSNY laser. We performed a histopathological study on eight Korean women who had considerable improvement in their melasma lesions after a series of low-fluence QSNY laser treatments. Compared with nonlesional skin, samples from melasma lesions show

Fractional bipolar RF provides clinical efficacy with safety in acne scars and enlarged pores through dermal matrix remodeling combined with tolerable epidermal ablation.

Our data suggests that PL may represent an inflammatory condition induced by various triggering agents, such as HHV-8, rather than a lymphoproliferative disorder. PLEVA, characterized by an acute course with severe symptoms, may indicate a relative lack of regulatory T-cells in comparison with PLC.

Meralgia paresthetica is a rarely encountered sensory mononeuropathy characterized by paresthesia, pain or sensory impairment along the distribution of the lateral femoral cutaneous nerve (LFCN) caused by entrapment or compression of the nerve as it crossed the anterior superior iliac spine and runs beneath the inguinal ligament. There is great variability regarding the area where the nerve pierces the inguinal ligament, which makes it difficult to perform blind anesthetic blocks. Ultrasound has

There is a lack of nationwide studies examining the epidemiology and comorbidities of psoriasis vulgaris (PsV) and psoriatic arthritis (PsA) in Asian populations. The purpose of this study is to determine the demographics of psoriasis in Korea along with the incidence of cerebro-cardiovascular (CV) comorbidities and to compare these risks between populations with PsA and with PsV. This cohort study identified 15 484 patients with psoriasis among 855 003 subjects in the Korean National Health Ins

The aim of this study was to evaluate the infectious complications after living donor liver transplantation (LDLT) in children. We enrolled 95 children (38 boys and 57 girls) who underwent LDLT from 1994 to 2004. The median age was 22 months (range, 6 months to 15 yr). We retrospectively investigated the proven episodes of bacterial, viral, and fungal infection. There occurred 150 infections in 67 (70%) of 95 patients (1.49 infections/patient); 74 in 43 patients were bacterial, 2 in 2 were funga

A high cephalosporin sensitization rate (17.4%) was detected by ELISA in HCW exposed to cephalosporins. Monitoring of serum specific IgEs to cephalosporin-HSA conjugates will be useful for detecting sensitized subjects.

A combination of three different energy sources, with bipolar RF, in one session is effective without further downtime for solving multiple problems including tone, texture, and laxity observed in photoaged Asian skin.

Irradiation using an AFR laser may induce the expression of Wnt5a, CYR61, and HSP90 in human skin during the early remodeling phases, suggesting that the induction of proteins may be the preceding event that is associated with the clinical effects of laser treatment.

OK-432 (picibanil) is an inactivated preparation of Streptococcus pyogenes that causes pleurodesis by inducing a strong inflammatory response. Intrapleural instillation of OK-432 has recently been used to successfully treat neonatal and fetal chylothorax. Here we report a trial of intrapleural instillation of OK-432 in two preterm infants who were born with hydrops fetalis and massive bilateral pleural effusion. Both cases showed persistent pleural effusion, refractory to conservative treatment,

Background: High-precision human leukocyte antigen (HLA) genotyping is crucial for anti-cancer immunotherapy, but existing tools predicting HLA genotypes using next-generation sequencing (NGS) data are insufficiently accurate. Materials and Methods: We compared availability, accuracy, correction score, and complementary ratio of eight HLA genotyping tools (OptiType, HLA-HD, PHLAT, seq2HLA, arcasHLA, HLAscan, HLA*LA, and Kourami) using 1,005 cases from the 1000 Genomes Project data. We created a
