Seventy-percent of Americans search health information online, half of whom access medical content on social media websites. In spite of this broad usage, the medical community underutilizes social media to distribute preventive health information. This project aimed to highlight the promise of social media for delivering skin cancer prevention messaging by hosting and quantifying the impact of an online video contest. In 2010 and 2011, we solicited video submissions and searched existing YouTube videos. Three finalists were selected and ranked. Winners were announced at national dermatology meetings and publicized via a contest website. Afterwards, YouTube view counts were monitored. No increase in video viewing frequency was observed following the 2010 or 2011 contest. This contest successfully identified exemplary online sun safety videos; however, increased viewership remains to be seen. Social media offers a promising outlet for preventive health messaging. Future efforts must explore strategies for enhancing viewership of online content.
Dermatitis I Allergic contact dermatitis I Atopic dermatitis Opinion statement Allergic contact dermatitis (ACD) is a type IV (delayed) hypersensitivity reaction that has a wide spectrum of presentations that often imitate or overlap with other cutaneous eruptions. Differential diagnoses to consider include infections, skin lymphoma-malignancies, inflammatory dermatoses, nutritional deficiencies, and mechanical causes of tissue damage. We discuss clues to the diagnosis of ACD, such as pruritus, localization to the area of skin contact with the allergen, recurrence with repeat exposures, and supportive skin biopsy histology. Epicutaneous patch testing remains the gold standard for diagnosing ACD. Definitive treatment is contact allergen avoidance and, when indicated, dietary restriction. With these measures, most patients will improve clinically. In cases where avoidance measures and interim topical therapies fail, ultraviolet light therapy or systemic immunosuppression may be considered. Key points 1. Allergic contact dermatitis (ACD) is a type IV (delayed) hypersensitivity reaction with a range of clinical presentations. 2. Mimickers of ACD include infections, skin lymphoma-malignancies, inflammatory dermatoses, nutritional deficiencies, and mechanical causes of tissue damage. 3. Allergen avoidance, which might include dietary restriction, is the definitive treatment for ACD.
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.
