The first broad replication study of SNPs and a pilot genome-wide association study for androgenetic alopecia in Asian populations.

Background: Many candidate genes for androgenetic alopecia (AGA) have been identified in studies of the Caucasians and some Asian populations.

Aims: This study aimed to confirm the known susceptibility genes reported in previous studies and find additional candidate genes for high-risk individuals for AGA in Korean population.

Patients/methods: We recapitulated the previously reported SNPs and identified the novel Korean AGA risk genetic variants using a Korean hospital-based AGA case and control samples.

Socioeconomic factors influencing cosmetic usage patterns.

Despite daily exposure to chemicals in cosmetic products, there are few studies on the exposure levels to cosmetics particularly in Asians. We sought to investigate the usage pattern of cosmetics, including eye makeup products, fragrances, color makeups, and hair and nail care products, in Koreans. An online survey of 1,800 participants (908 males and 892 females, aged 15-59 years) from 5 Metropolitan cities (Seoul, Incheon, Daejeon, Daegu, and Busan) in Korea was conducted.

Large dermal non neural granular cell tumor on the surgical wound site.

Granular cell tumors (GCTs) can be divided into neural type with S-100 reactivity and non-neural type without that. The latter has not been widely recognized and there are only fewer reports available when compared to conventional GCT. A 65-year-old man was presented with the presence of a painless mass on his back.
