Abstract:
Traction alopecia is a protracted form of hair loss resulting from persistent tension on the hair follicle . We report a case of a 9-year-old African American girl who presented with extensive scalp ulceration and alopecia 11 days after placement of a synthetic hair braid. Over a period of months, with consistent wound care and low-tension hairstyling, most of the hair regrew. We propose that the ulceration and hair loss in this case represents an acute variant of traction alopecia due to pressure-induced ischemia and necrosis.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
