Up to 15 billion dollars of US health care expenditure each year is consumed by treatment of poorly healing wounds whose etiologies are often associated with aberrancies in tissue oxygenation. To address this issue, several modes of tissue oxygen delivery systems exist, including Hyperbaric Oxygen Therapy (HBOT) and Topical Oxygen Therapy (TOT), but their efficacies have yet to be fully substantiated. Micro/nanobubbles (MNBs), which range anywhere from 100 μm to <1 μm in diameter and are relatively stable for hours, offer a new mode of oxygen delivery to wounds. The aim of this article is to systematically review literature examining the use of TOT for wound healing and use of MNBs for tissue oxygenation using the MEDLINE database. The search yielded 87 articles (12 MNB articles and 75 TOT articles), of which 52 met the inclusion criteria for this literature review (12 MNB articles and 40 TOT articles). Additionally, we present an analysis on the efficacy of our MNB generating technology and propose its use as a wound healing agent.
Mixed reality, a blending of the physical and digital worlds, can enhance the surgical experience, leading to greater precision, efficiency, and improved outcomes. Various studies across different disciplines have reported encouraging results using mixed reality technologies, such as augmented and virtual reality. To provide a better understanding of the applications and limitations of this technology in plastic surgery, we performed a systematic review of the literature in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The initial query of the National Center for Biotechnology Information database yielded 2544 results, and only 46 articles met our inclusion criteria. The majority of studies were in the field of craniofacial surgery, and uses of mixed reality included preoperative planning, intraoperative guides, and education of surgical trainees. A deeper understanding of mixed reality technologies may promote its integration and also help inspire new and creative applications in healthcare.
Background: Cleft lip affects one in 700 children globally, and the prevalence far surpasses capacity to deliver cleft care in underresourced and endemic regions. A hands-on educational presence is needed to promote overseas surgical autonomy, build overseas capacity, and ensure a sustained clinical and educational infrastructure. The goal of this study was to build and assess an augmented reality educational platform that allows a remote yet virtual interactive presence to transfer cleft surgery knowledge/skills to overseas colleagues. Methods: A prospective study assessing a 13-month overseas augmented reality–based cleft surgery curriculum was conducted. Three semiannual site visits engaged two Peruvian surgeons in evidence-based didactics, on-site cleft surgery, and familiarization with the augmented reality platform. During 10 remote augmented reality visits, a surgeon stationed in United States guided the same Peruvian surgeons through cleft surgery. Quarterly assessments of the Peruvian surgeons were performed using visual analogue scale questionnaires. Results: Visual analogue scale scores by both the remote and overseas surgeons demonstrated significant, progressive improvement in all facets of cleft lip repair throughout the curriculum. Site visits preferentially built capacity for cleft diagnosis and preoperative counseling (p < 0.001), principles of repair (p < 0.001), repair technique (p < 0.02) and intraoperative decision-making (p < 0.001). Remote sessions preferentially developed understanding of cleft operative design/anthropometry (p < 0.04), cleft anatomy (p < 0.01), and operative efficiency (p < 0.001). At 30-month follow-up, no children with cleft lip required transfer to tertiary care centers. Conclusion: A curriculum that combines on-site training and augmented reality–based hands-on remote teaching can build sustained capacity of comprehensive cleft care in underresourced areas.
Background: Social media play an important role in plastic surgery, yet there are limited studies in the literature to guide plastic surgeons’ social networking practices. To address this deficiency and provide further insight, the authors set out to investigate the public’s attitude toward plastic surgery using Twitter, a popular social media platform. The authors examined a large body of messages (tweets) related to plastic surgery using novel techniques of natural language processing and sentiment analysis. Methods: The authors collected over 1 million tweets with the keywords “plastic,” “cosmetic,” “aesthetic,” and “reconstruction” surgery spanning from 2012 to 2016 from the Twitter Gardenhose feed. Using hedonometrics, the authors extracted the average happiness/positivity (h avg) of tweets and created word-shift graphs to determine the most influential words. Results: The positivity scores for keywords “plastic,” “cosmetic,” “aesthetic,” and “reconstruction” surgery were 5.72, 6.00, 6.16, and 6.09, respectively. In relation to “plastic,” keywords “cosmetic” and “aesthetic” were more positive because they lacked antagonistic words, such as “fake,” “ugly,” “bad,” “fails,” or “wrong.” The keyword “reconstruction,” however, was more positively associated than the term “plastic” because of an increase in positive words, such as “honor,” “amazing,” “successful,” and “respect.” Conclusions: Tweets containing the term “plastic” surgery trended toward negativity, and may be explained by the increase in unfavorable, associative words. Conversely, related terms such as “aesthetic,” “cosmetic,” and “reconstruction” were more favorably regarded because of the lack of antagonistic words and the presence of supportive words. The authors’ results are informative and may serve to guide plastic surgeons’ social media practices.
Background: Ulnar polydactyly is frequently encountered in the newborn nursery and is commonly treated with bedside suture ligation. However, growing concern about the complications associated with suture ligation has led some practitioners to advocate for primary surgical excision instead. Thus, we set out to compare outcomes of suture ligation and surgical excision by systematic appraisal of the literature. Methods: Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic review was performed to identify studies published between 1950 and 2017 that described outcomes of suture ligation, surgical excision, or both. Baseline characteristics, complications, and study quality were extracted for each included article. Results: A total of 900 articles were reviewed, of which 10 studies (8 case series, 2 comparative analyses) met the inclusion criteria. There was considerable heterogeneity among the studies with respect to patient characteristics and reported outcomes. There were 2 retrospective case series of suture ligation that reported no acute complications and a variable proportion of patients with residual remnants or neuromas. Studies evaluating surgical ligation reported no acute or long-term complications, with only 1 case series reporting a small percentage of residual remnants. However, in the largest cohort analysis, the difference in complication rate was reported to be as high as 23.5% for suture ligation compared with 3% for surgical excision. Conclusions: There is a paucity of literature limiting the comparison of suture ligation and surgical excision for ulnar polydactyly. Further studies are required to determine the optimal treatment.
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.
