Sir:FigureTo date, the most promising innovation in medicine is stem cells. Over the past decade, a remarkable number of articles have been published regarding stem cells.1–5 Novel research and innovation are essential for the improvement of plastic surgery. We think that stem cell research is exceedingly important for improvement of plastic surgery. Therefore, in this study, we evaluated stem cell publications in plastic surgery–related journals between 2001 and 2009. We downloaded records from PubMed over the Internet. The search strategy used the phrase “stem cell” in articles between 2001 and 2009. The analysis was limited to articles that were already published. Articles in press were excluded. All types of articles were included, such as original articles, editorial materials, letters, case reports, and others. Articles in all languages were included. The total number of stem cell studies per year was identified. After downloading, the articles related to plastic surgery were extracted. Of these articles affiliated with plastic surgery, we extracted articles published in the journals most commonly regarding plastic surgery, to evaluate the interest of plastic surgery related journals into stem cell studies. Plastic and Reconstructive Surgery, Annals of Plastic Surgery, Aesthetic Plastic Surgery, Burns, Clinics in Plastic Surgery, Journal of Craniofacial Surgery, Journal of Oral and Maxillofacial Surgery, and Wound Repair and Regeneration were selected as data sources. The number of articles in these journals was compared with the total number of the publications per each year, between 2001 and 2009. The analysis of publications was stratified by publication year, journal, and countries of the authors' affiliations. The countries of the authors' affiliations were identified from the addresses in their affiliations and correspondences. There were 20,072 articles published in the literature between 2001 and 2009. The number of the publications increased annually, reaching a peak of 4037 in 2009 (Fig. 1). The affiliation of these articles to plastic surgery was 212. One hundred forty-nine of these 212 articles (70 percent) affiliated with plastic surgery were published in the journals most commonly regarding plastic surgery. Most of these articles were published in Plastic and Reconstructive Surgery (43 percent), Wound Repair and Regeneration (17 percent), and Journal of Craniofacial Surgery (13 percent) (Table 1). Authors from 20 countries contributed to publications in the journals most commonly regarding plastic surgery. The top five countries are the United States (50.3 percent), Japan (16.7 percent), China (11.4 percent), Italy (4.6 percent), and South Korea (3.3 percent). The top five centers are the University of California (11 articles), Harvard Medical School (seven articles), Stanford University School of Medicine (seven articles), the University of Pittsburgh (seven articles), and the University of Tokyo School of Medicine (five articles). Disregarding the possibility of authors having the same name, 668 authors contributed to publications. Most authors were presented in only one article, and 129 authors were present in two or more articles.Fig. 1: The annual number of stem cell studies in the literature between 2001 and 2009.Table 1: Annual Number of Stem Cell Studies in Plastic Surgery JournalsIn conclusion, this article provides an overview of the stem cell studies published in the journals most commonly regarding plastic surgery. The background of the articles was analyzed, and an overview of the stem cell studies in plastic surgery was emphasized.
