Updates on disorders in curly hair.

Hair disorders, including central centrifugal cicatricial alopecia (CCCA), traction alopecia (TA), and acquired trichorrhexis nodosa (ATN), commonly occur in individuals with curly textured hair. Curly textured hair in individuals of African descent has unique properties and can present diagnostic and therapeutic challenges. CCCA has been linked to uterine leiomyoma and type 2 diabetes mellitus, as well as fibroproliferation. TA often presents with a fringe sign and can arise from high-tension hairstyles presumed to be protective. Trichoscopy is useful in establishing a diagnosis; perifollicular halos are more commonly seen than perifollicular erythema or scale in CCCA. In TA, miniaturized follicles, hair casts, and "flambeau sign" can be seen. Hairstyling practices likely contribute to TA and ATN; however, the data are mixed on the role of chemical relaxers and heat styling in CCCA. Unique considerations in the presentation of frontal fibrosing alopecia in curly textured hair have also been published recently. This review provides a comprehensive, up-to-date summary of these disorders with an emphasis on their unique properties, as well as considerations in hair care for curly textured hair.

Teaching motivators, facilitators, and barriers among dermatology volunteer clinical faculty.

Volunteer clinical faculty in private practice provide important clinical teaching and mentorship to dermatology residency programs. Motivations for serving as volunteer clinical faculty in specialties such as obstetrics and gynecology, emergency medicine, and family medicine have been identified; however, there is limited data on what drives private practice physicians to volunteer to teach in dermatology residency training programs. This study examined motivators, facilitators, and barriers to serving as volunteer clinical faculty using an anonymous survey of dermatologists, Mohs surgeons, and dermatopathologists affiliated with Emory University's dermatology residency program. Among the 38 invited participants, 26 (68%) completed the survey. The types of practices represented include general dermatology (71%), Mohs surgery (23%), cosmetic dermatology (58%), and dermatopathology (27%). Traditional lectures and impromptu teaching sessions were the most utilized teaching modalities, with 14 (54%) and 11 (42%) of respondents reporting usage, respectively. Most respondents ranked altruistic statements such as "opportunity to be helpful to others" (26, 100%), "providing service to the field of dermatology" (25, 96%), and "enjoyment of teaching" (25, 96%) as important motivations. In contrast, extrinsic rewards such as career advancement and increased income were rated as least important. Significant barriers included limited time for travel and teaching and credentialing. Proposed facilitators included promoting schedule flexibility, increasing teaching supplies, and streamlining credentialing. This single-center study may have limited generalizability to other residency programs with varying characteristics. The motivators, facilitators, and barriers identified by this survey can inform dermatology residency programs on how to maximize volunteer clinical faculty recruitment, retention, and engagement, thus strengthening clinical teaching and mentorship offered.

Angiogenesis in cutaneous lesions of leprosy: implications for treatment.

OBJECTIVE: To examine the potential role of angiogenesis in leprosy. DESIGN: Immunohistochemical analysis of leprosy lesions. SETTING: Department of Dermatology, Venereology, and Leprology, Kasturba Medical College; Division of Dermatology, University of California at Los Angeles; and Departments of Dermatology and Pathology, Emory University. PATIENTS: Thirty-two cutaneous lesions that represented the spectrum of leprosy were obtained from 32 patients. MAIN OUTCOME MEASURE: CD31 microvessel counts. RESULTS: The mean CD31 microvessel count in borderline tuberculoid, midborderline, and lepromatous leprosy lesions was significantly higher than in indeterminate leprosy lesions. CONCLUSIONS: Increased bacterial load is associated with increased angiogenesis. Angiogenesis inhibitors may be of benefit in the treatment of leprosy.
