Pseudofolliculitis barbae (PFB) and acne keloidalis nuchae (AKN) are chronic inflammatory conditions affecting hair follicles common in men of color who are genetically inclined to have tightly curled hair. 1 The incidence of PFB and AKN among African American men may be as high as 83.0% and 13.6%, respectively. 2,3 The barbershop represents a distinctly important institution in the African American community and constitutes a culturally appropriate venue for barbers to provide men with health information. 4 The knowledge and expertise afforded by barbers regarding dermatologic evaluation and intervention of common scalp and hair problems in this population has not been evaluated. The aim of this cross-sectional study was to assess barber perceptions and recommendations regarding PFB and AKN in predominantly African American barbershops.
Peristomal ulcer with cutaneous intestinal metaplasia, defined by scattered colonic crypts within variably intact epidermis, is an exceedingly rare pathologic diagnosis, which possesses the potential to progress to primary adenocarcinoma. Herein, we report the third case of cutaneous intestinal metaplasia in a peristomal ulcer and
hyperhidrosis (Table 1). Topical glycopyrrolate preparations have been reported to be successful outside of the United States. 3 Isolated cases have reported use of oxybutynin with success, however, the associated systemic anticholinergic side effects make it less than ideal. 4,5 Injections of botulinum toxin-A are effective, but may be painful, have insurance coverage barriers, or be cost-prohibitive. 6 Topical aluminum chloride has been used successfully in treating gustatory hyperhidrosis in Frey syndrome, and but there is a scarcity of literature describing the successful use of aluminum chloride to treat diabetic gustatory hyperhidrosis. 7,8 Aluminum chloride is an inexpensive medication used to reduce focal sweating. Aluminum ions form a precipitate with mucopolysaccharides in the sweat ducts, physically obstructing the flow of sweat and damaging epithelial cells along the lumen of the duct. 9 This obstruction is temporary however, and normal sweat gland function returns with epidermal renewal, thus necessitating continued therapy.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
