Biologic agents have become more common to treat patients with psoriasis, but concerns about their effect on pregnancy and lactation often preclude this treatment during these time periods. During the past decade, we have gained a much better understanding of the course of psoriasis during pregnancy and the safety of the use of biologic agents during pregnancy and lactation. Under certain circumstances, biologic agents can be considered appropriate treatment options for patients who are pregnant or lactating.

Background Patients with skin of color are at risk for skin cancer, pigmentary disorders, and photo-exacerbated conditions but find it challenging to use sunscreens on the market that leave an obvious residue on their skin. Objective The objective of this study was to examine sunscreen recommendations from the popular press and from practicing dermatologists for patients with skin of color. Methods We queried the Google search engine with the following search terms: “Sunscreen” with “skin of color,” “dark skin,” “black skin.” For comparison, we also searched for “sunscreen” with “white skin,” “pale skin,” and “fair skin.” We conducted an anonymous survey regarding sunscreen recommendations among dermatology trainees and board-certified dermatologists. Results Websites with recommendations on sunscreens for patients with skin of color compared with sunscreens for white or fair skin were more likely to recommend chemical sunscreens (70% vs. 36%) and more expensive products (median: $14 vs. $11.3 per ounce), despite the lower sun protection factor level (median: 32.5 vs. 50). In our survey study, dermatologists were overall cost-conscious and felt that sun protection factor level, broad spectrum (ultraviolet A/B protection), and price were the most important features of sunscreens for their patients. Cosmetic elegance was deemed least important. Dermatologists overall counseled patients with skin of color less on sunscreen use, and 42.9% reported that they either never, rarely, or only sometimes take patients’ skin type into account when making sunscreen recommendations. Conclusion These data represent an area for growth within dermatology to improve culturally competent care by gaining familiarity with sunscreen types and formulations that are geared toward patients with skin of color.

Hidradenitis suppurativa (HS) is a complex disease with a dramatic impact on the quality of life of patients that it afflicts. Despite this, there are few treatment options offering long-term relief. The exact pathophysiology of HS is unclear, although the current theory involves follicular obstruction, rupture, and subsequent inflammation leading to fistula and abscess development in intertriginous skin. Several inflammatory modulators have been implicated in the development of HS, including tumor necrosis factor (TNF)-α as well as interleukin (IL)-1β, IL-10, and IL-17. Initial evidence for the use of TNF-α inhibitors in HS stemmed from recognition that inflammatory bowel disease patients treated with these medications saw a concurrent improvement in their HS symptoms. Early case reports and case series illustrated TNF-α inhibitors’ value in the treatment of HS. Later, two phase III clinical trials, PIONEER I and PIONEER II, demonstrated that adalimumab is an efficacious treatment for HS. Infliximab represents another effective HS treatment option with its main advantage being dosing flexibility. In contrast, clinical trials have failed to show evidence for application of etanercept in HS. There is limited data on other TNF-α inhibitors such as certolizumab-pegol and golimumab. This review outlines the history, dosing, response, and adverse effects of TNF-α inhibitors in the treatment of HS.
