Non-celiac gluten sensitivity is often clinically indistinguishable from celiac disease, and patients show improvement or resolution of their symptoms with a gluten-free diet. In contrast to celiac disease, the effects of gluten on the skin and hair in the context of non-celiac gluten sensitivity are not as clear. This review aims to describe the impact of gluten on the skin and hair in patients with non-celiac gluten sensitivity and those without a definitive celiac disease diagnosis. A literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guidelines for systematic reviews. Forty-two publications met inclusion criteria with five studies describing the skin manifestations of non-celiac gluten sensitivity. Trials identifying the impact of a gluten-free diet on skin disease, as well as dermatologic conditions and their associations with antigliadin antibodies were also identified. Dermatologic manifestations in patients with non-celiac gluten sensitivity vary and may be non-specific. It may be appropriate for some of these patients with skin manifestations to trial a gluten-free diet. Dermatologic conditions that may respond positively to a gluten-free diet include psoriasis, atopic dermatitis, vitiligo, and palmoplantar pustulosis, while linear IgA disease does not appear to improve with this dietary change.

One of the many consequences of the COVID-19 pandemic was the cancelation of the 2020 American Academy of Dermatology Annual Meeting. This conference historically features lectures from world-renowned experts in all areas of dermatology, thus providing an important educational experience for dermatology residents. We hypothesized that the cancellation of this meeting produced a substantial educational loss for dermatology residents. To mitigate this impact, we developed a virtual faculty exchange program and surveyed dermatology residents' perspectives on its implementation. All participating residents found the virtual faculty exchange useful and would recommend it to other residents/programs. Moreover, all residents wanted to participate in more faculty exchange sessions as well as incorporate them throughout the academic year. Additionally, this educational program eliminated the potential cost of >$15,000 in flights and >24 metric tons of carbon emissions. This virtual faculty exchange program is a viable tool to enhance dermatology resident education in the COVID-19 era.

The treatment of cutaneous squamous cell carcinoma in situ by Mohs micrographic surgery is currently deemed as appropriate by the Mohs Appropriate Use Criteria. However, squamous cell carcinoma in situ is a very superficial, indolent, low-risk tumor amenable to destructive and non-surgical treatments. It is uncommon for squamous cell carcinoma in situ to have progressed to invasive malignancy subsequent to definitive management. The suggestion that squamous cell carcinoma in situ on certain anatomic locations has a poorer prognosis is widely assumed but lacks an evidence base. We recommend that most primary squamous cell carcinoma in situ in non-immunosuppressed patients be scored inappropriate or uncertain for Mohs micrographic surgery by the Mohs Appropriate Use Criteria. Multiple other efficacious treatment options exist for managing squamous cell carcinoma in situ, including curettage and cryotherapy, curettage and electrodessication, and topical therapies.

Because there are important distinctions between ablative and non-ablative laser resurfacing, accurate and effective patient education is paramount. However, as more patients use the internet as a resource for medical information, little is known about the content and readability of these sources. Thus, we sought to evaluate the readability of major online resources about laser resurfacing while recognizing the recommendations by the American Medical Association and National Institutes of Health. An internet search for the term "Laser Resurfacing" was performed. The first 9 results were identified, patient information from each of these 9 sites were downloaded, and a total of 25 articles were examined. Readability was analyzed using 7 different established tests. Analysis demonstrated an average grade level of at least 9th grade, with all articles exceeding the recommended 6th grade reading level, emphasizing that these resources are too challenging for many patients to read and comprehend. Such materials may hamper appropriate decision-making in patients considering the use of a laser for their dermatologic conditions. The potential detrimental effect on the opinion, participation, and satisfaction of laser resurfacing should spur dermatologists to be more critical of online patient materials and motivated to produce more appropriate resources.

Comma and corkscrew hairs are trichoscopic markers of tinea capitis. Although comma hairs have been reported in both black and white patients with tinea capitis, corkscrew hairs were previously hypothesized to manifest exclusively in patients with curly or African hair types. However, we report a significant number of comma and corkscrew hairs in a Hispanic female patient with naturally straight hair and Trichophyton tonsurans tinea capitis. Thus, dermoscopy is a rapid, noninvasive, and cost-effective tool for evaluating tinea capitis and should be used in combination with culture in all patients regardless of hair texture or race.

Gel manicures have become a popular beauty trend in recent years. The specially formulated nail polish must undergo curing under light-based units. The majority of these curing lamps emit high-intensity ultraviolet A, which can cause skin damage and increase the risk for skin cancers. Incorporating relevant information in patient education endeavors can help them practice avoidance, apply broad-spectrum sunscreen prior, or use nitrile exam gloves in order to prevent photoaging and skin cancer resulting from these procedures.

This manuscript addresses the significantconsiderations concerning the development anduse of medical devices in dermatology. With therapidly growing demand and booming marketfor medical devices, especially lasers, it is crucialthat dermatologists become familiar with thenuances associated with supporting clinical studies,consumer-driven marketing strategies, and thecomplex relationships that exist between physicians,industry, and consumers. An examination of theserelationships includes an overview of the potentialbiases pertaining to advisory panels and treatingclinicians. The aim of this paper is to serve as anintroduction to the background of medical devicesand to offer dermatologists important informationon what should be considered before recommendingtreatment.

In dermatology, a particularly common ethical dilemma can arise when the skin lesions of bystanders are inadvertently viewed in public settings. Dermatology is a unique field, where a person’s organ of interest is readily visible to others. When lesions are suspicious for skin disease, unsolicited medical opinions may or may not be given depending on several factors. This study examined the actions and attitudes of dermatologists with different levels of experience through the use of case scenarios with various settings and skin lesions.
