Severe Scalp Psoriasis Microbiome Has Increased Biodiversity and Relative Abundance of Pseudomonas Compared to Mild Scalp Psoriasis.

Psoriasis is a chronic inflammatory skin disease associated with various factors. Recently, alterations in the gut and skin microbiomes have been shown to interact with host immunity, affect skin barrier function, as well as development and progression of psoriasis. We aimed to analyze the microbiota of the scalp of patients with psoriasis and determine the characteristics of the microbiome according to disease severity.

Astaxanthin Protects Ultraviolet B-Induced Oxidative Stress and Apoptosis in Human Keratinocytes via Intrinsic Apoptotic Pathway.

Background: Ultraviolet radiation causes skin damage due to increased production of reactive oxygen species (ROS) and inflammatory intermediates and direct attack of DNA of skin cells. Astaxanthin is a reddish pigment that belongs to a group of chemicals called carotenoids and has protective effects as an antioxidant.

Objective: To determine the beneficial effects of astaxanthin on damaged human skin after exposure to ultraviolet radiation.

Identification of genetic mutations of cutaneous squamous cell carcinoma using whole exome sequencing in non-Caucasian population.

Background: Cutaneous squamous cell carcinoma (cSCC) is the second most common nonmelanoma skin cancer worldwide. Recent studies have reported several genetic mutations in development of cSCC such as TP53, HRAS, and NOTCH1. Whole-exome sequencing (WES) of cSCC has not been reported in East Asian populations.

A Phase 3, Randomized, Multi-center Clinical Trial to Evaluate the Efficacy and Safety of Neu-BoNT/A in Treatment of Primary Axillary Hyperhidrosis.

Background: Botulinum toxin type A is widely used to treat primary axillary hyperhidrosis and has proven to be an effective and safe approach. Onabotulinumtoxin A was approved by the FDA as a treatment for primary axillary hyperhidrosis. This study aimed to evaluate the efficacy and safety of Neu-BoNT/A in subjects diagnosed with primary axillary hyperhidrosis.

Incidence and death rate of sarcoidosis in Korea in association with metabolic diseases.

Sarcoidosis is a systemic granulomatous disease that affects a variety of organs. Although the etiology has not been fully understood, it is thought that diverse genetic and environmental factors interact with the immune system to develop granulomas. The incidence and death rate of sarcoidosis vary according to race.

NaHCO- and NaCl-Type Hot Springs Enhance the Secretion of Inflammatory Cytokine Induced by Polyinosinic-Polycytidylic Acid in HaCaT Cells.

Background: Background: Hot springs have been traditionally used as an alternative treatment for a wide range of diseases, including rheumatoid arthritis, bronchial asthma, diabetes, hypertension, psoriasis and atopic dermatitis. However, the clinical effects and therapeutic mechanisms associated with hot springs remain poorly defined.

Objective: The purpose of this study was to demonstrate the different effects of hot springs on cellular viability and secretion of inflammatory cytokines on keratinocyte in two geographically representative types of hot springs: NaHCO-type and NaCl-type, which are the most common types in South Korea.

Positive association between actinic keratosis and internal malignancies: a nationwide population-based cohort study.

Little is known about the comorbidities in actinic keratosis patients. To evaluate the association of actinic keratosis with certain malignancies. All patients with actinic keratosis (n = 61,438) and age- and sex-matched control subjects (n = 307,190) at a 5:1 ratio were enrolled using data from the Korean National Health Insurance Service between the years 2007 and 2014.

Investigation of Genetic Mutations in High-risk and Low-risk Basal Cell Carcinoma in a Non-Caucasian Population by Whole Exome Sequencing.

This study analysed genomic mutations in basal cell carcinoma using whole exome sequencing of DNA specimens obtained from 20 Korean patients. Histological evaluation determined that 15 (75%) were low-risk basal cell carcinomas, and 5 (25%) were high-risk basal cell carcinomas. Seventy-five percent of the basal cell carcinomas harboured somatic mutations in hedge-hog pathway genes (PTCH1, 40% and SMO, 50%) and 45% harboured mutations in TP53.

A Case of Eccrine Poromatosis in a Patient with a History of Chemotherapy Due to Stomach Cancer.

An eccrine poroma (EP) is a benign adnexal tumor that typically presents as a single lesion. Eccrine poromatosis defined as multiple EPs is an uncommon presentation. A 54-year-old male had undergone operation for stomach cancer 10 years prior and insisted that he had also taken adjuvant chemotherapy.

Association between vitiligo and smoking: A nationwide population-based study in Korea.

No study has examined the associations between vitiligo and smoking. The purpose of this study was to investigate the incidence of vitiligo according to smoking status. We used clinical data from individuals aged over 20 years who received a health examination in the National Insurance Program between 2009 and 2012 (n = 23,503,807).

Increased Cardiovascular Risk and All-cause Death in Patients with Behçet Disease: A Korean Nationwide Population-based Dynamic Cohort Study.

Objective: Behçet disease (BD) is a chronic inflammatory multiorgan disease. An increased risk of cardiovascular disease (CVD) and heightened death rate with BD have been suggested, but to our knowledge, a nationwide large-scale study has not been conducted to date. This study aimed to determine the overall CV risk and death rate in patients with BD versus controls using the Korean National Health Insurance Service claim database.
