Background Social media platforms are increasingly used by patients to research and discuss medical problems. Objective The aim of this study was to identify by whom, how frequently, and in what manner allergic contact dermatitis (ACD) is discussed on social media sites. Methods Search terms “allergic contact dermatitis” and “contact dermatitis” were queried across Twitter, Instagram, Reddit, Facebook, YouTube, and Google search metrics. The frequency, content, and creators of the content were assessed. Results ACD content was identified on all platforms, generated by by patients, physicians, professional organizations, and companies. When comparing the volume of posts, more content was on Instagram than Twitter, particularly among patients. Patient support groups were identified on Facebook but not on Reddit. A formal analysis of YouTube videos found that the medical information presented in these videos was often of poor quality. Conclusions Patch testing physicians should be aware that information on ACD exists across social media sites. While some content is generated by physicians, patients and industry groups also post and share material. Patch testing physicians should know that there is an opportunity to share ACD information, but they should also be aware that patients are posting and creating online support communities independent of physicians. Highlights Online support communities exist for patients with ACD on Facebook. Online information is of lower quality, with a mean QUEST quality score of 7.4/28 on reviewed YouTube videos. Of the five social media sites reviewed, patients are most active on Instagram, Reddit, and Facebook. Approximately 9000 Google searches per month are conducted using contact dermatitis‐related search terms. Differences in terminology exist between physicians and non‐physicians. While the most popular hashtag term was “contact dermatitis”, physicians disproportionately authored posts tagged with “allergic contact dermatitis.”

Introduction: Drain use in total knee arthroplasty (TKA) remains controversial. Use has been associated with increased complications, particularly post-operative transfusion, infection, increased cost, and longer hospital stays. However, studies examining drain use were performed before widespread adoption of tranexamic acid (TXA) which markedly reduces transfusion without increasing VTE events. We aim to investigate incidence of post-operative transfusion and 90-day return to the operating room (ROR) for hemarthrosis in TKA with use of drains and concomitant intravenous TXA. Methods: Primary TKAs from a single institution were identified from August 2012-December 2018. Inclusion criteria were primary TKA, age 18 years and over where use of TXA, drains, anticoagulant, and pre-and post-surgical Hb were documented during the patient’s admission. Primary outcomes were 90-day ROR specifically for hemarthrosis and rate of post-operative transfusion. Results: A total of 2008 patients were included. Sixteen patients required ROR, three of which were due to hemarthrosis. Drain output was statistically higher in the ROR group (269.3mL vs. 152.4mL (p = 0.05)). Five patients required transfusion within 14 days (0.25%). Patients requiring transfusion had significantly lower presurgical Hb (10.2g/dL, p=0.01) and 24-hr postoperative Hb (7.7g/dL, p< 0.001). Drain output between the transfusion and no transfusion groups varied significantly (p=0.03), with transfusion patients having higher POD 1 drain output of 362.6mL and total drain output of 376.6mL. Conclusion: In this series, post-operative drain use with concomitant weight-based IV TXA is shown to be safe and efficacious. We observed exceedingly low risk of post-operative transfusion compared to prior reports of drain use alone, as well as preserved low rate of hemarthrosis that has previously been positively linked to drain use.
