Telogen Effluvium - a review of the science and current obstacles.

Telogen effluvium (TE) is a common cause of diffuse non-scarring hair loss that is usually precipitated by physiological stress such as childbirth or sudden weight loss. Despite its high rate of remission, this phenomenon of sudden excessive hair loss can be very worrisome and upsetting for affected individuals and may significantly impact their quality of life.

Should we biopsy melanonychia striata in Asian children? A retrospective observational study.

Background And Objectives: Melanonychia striata is common in children of darker-skinned Asian races, while subungual melanoma is extremely rare and it is difficult to make a diagnosis clinically. However, performing nail unit biopsies in children is particularly challenging and can result in permanent nail dystrophy. The aim of this study was to review the clinical and histologic characteristics of melanonychia striata in pediatric patients of Asian descent to aid in the clinical decision regarding nail biopsy.
