BACKGROUND Dutasteride (Avodart) is a dual inhibitor of both type I and type II 5 alpha reductases, and thus inhibits conversion of testosterone to dihydrotestosterone, a key mediator of male pattern hair loss. OBJECTIVES The aim of this randomized double-blind phase III study was to compare the efficacy, safety, and tolerability of dutasteride (0.5 mg)(More)
BACKGROUND Finasteride at a dose of 1 mg/d has been reported to show no significant improvement in 30-50% of patients with androgenetic alopecia (AGA). Dutasteride, a dual inhibitor of both type I and type II 5 alpha-reductase, inhibits the conversion of testosterone to dihydrotestosterone, which is the key contributor of AGA.

To elucidate the genes responsible for constitutive human skin color, we measured the extent of skin pigmentation in the buttock, representative of lifelong non-sun-exposed skin, and conducted a gene mapping study on skin color in an isolated Mongolian population composed of 344 individuals from 59 families who lived in Dashbalbar, Mongolia.

Tanning ability is important, because it represents the ability of the skin to protect itself against ultraviolet (UV) radiation. Here, we sought to determine genetic regions associated with tanning ability. Skin pigmentation was measured at the outer forearm and buttock areas to represent facultative and constitutive skin color, respectively. In our study(More)
Congenital hyperpigmentation in the acro-genital area and simultaneous occurrence of ganglioneuroma in the esophagus have yet to be reported. Herein, we report a 4-month-old girl presenting with feeding difficulty by esophageal ganglioneuroma and symmetrically distributed brown pigmented patches on the lips, axillae, dorsa of fingers and toes, and genital(More)
