    Autoimmune skin disease among dermatology outpatients in Botswana: a retrospective review
    (International journal of dermatology, 2019) Madu, Pamela N.; Williams, Victoria L.; Noe, Megan H.; Omech, Bernard; Kovarik, Carrie L.; Wanat, Karolyn A.
    Background There is a paucity of data describing autoimmune skin diseases in sub- Saharan Africa and in HIV positive cohorts. We describe the incidence of autoimmune skin diseases in public dermatology clinics in Botswana. Methods New patient records from public dermatology clinics were reviewed retrospectively for the period of September 2008 to December 2015. New diagnoses of cutaneous lupus erythematosus, systemic lupus erythematosus (SLE) with cutaneous involvement, dermatomyositis, systemic sclerosis, lichen sclerosus, bullous pemphigoid, pemphigus foliaceus, pemphigus vulgaris, and pemphigus vegetans were identified. Demographic data were recorded, and incidence was determined. Results A total of 262 patients were diagnosed with autoimmune skin disease (4% of all new patients) with an incidence rate of 28.8 (per 1,000,000). Cutaneous lupus was the most common diagnosis with discoid lupus occurring most frequently (12.6). The incidence of systemic sclerosis (2.2), morphea (1.6), lichen sclerosus (1.5), SLE with cutaneous involvement (1.3) and dermatomyositis (1.2) was relatively lower. Bullous pemphigoid was the most common bullous disease (3.8). Pemphigus foliaceus (0.9), pemphigus vulgaris (0.6), and pemphigus vegetans (0.2) were observed at a lower rate. At least 19.8% of these patients were also HIV positive. Conclusions The incidence of autoimmune skin diseases in Botswana is lower compared to other published studies in other geographic areas, which may be reflective of a younger population, barriers to access, genetic differences, and a lack of comparative studies in sub-Saharan Africa. The hygiene hypothesis and helminth infections may also contribute to these differences. Further studies are needed to understand these disorders in this region

    Novel Education Modules Addressing the Underrepresentation of Skin of Color in Dermatology Training
    (Journal of Cutaneous Medicine and Surgery, 2021) Slaught, Christa; Madu, Pamela; Chang, Aileen Y.; Williams, Victoria L.; Kebaetse, Masego B.; Nkomazana, Oathokwa; Molefe-Baikai, Onkabetse Julia; Bekele, Negussie A.; Omech, Bernard; Kellman, Philip J.; Krasne, Sally; Kovarik, Carrie L.
    Background: Representative images of pathology in patients with skin of color are lacking in most medical education resources. This particularly affects training in dermatology, which relies heavily on the use of images to teach pattern recognition. The presentation of skin pathology can vary greatly among different skin tones, and this lack of representation of dark skin phototypes challenges providers’ abilities to provide quality care to patients of color. In Botswana and other countries in sub-Saharan Africa, this challenge is further compounded by limited resources and access to dermatologists. There is a need for improved and accessible educational resources to train medical students and local medical providers in basic skin lesion description and diagnosis. Objectives: We examined whether online Perceptual and Adaptive Learning Modules (PALMs) composed of representative dark skin images could efficiently train University of Botswana medical students to more accurately describe and diagnose common skin conditions in their community. Methods: Year 4 and 5 medical students voluntarily completed PALMs that teach skin morphology, configuration, and distribution terminology and diagnosis of the most common dermatologic conditions in their community. Pre-tests, post-tests and delayed-tests assessed knowledge acquisition and retention. Results: PALMs training produced statistically significant (P < .0001) improvements in accuracy and fluency with large effect sizes (1.5, 3.7) and good retention after a 12.5-21-week median delay. Limitations were a self-selected group of students, a single institution, slow internet connections, and high drop-out rates. Conclusions: Overall, population-specific PALMs are a useful tool for efficient development of pattern recognition in skin disease description and diagnosis.
