Background: Vitiligo is a common depigmenting disorder with a prevalence of 0.5–2%. Despite the increasing popularity of bibliometric studies in recent years, medical literature lacks a report investigating bibliometric features of vitiligo literature. Aim: It was aimed to analyze vitiligo literature by evaluating productivity of countries, institutions, and authors, and performing assessment of publication trends, bibliometric networks, and correlations. Material and Methods: We collected all data in this study by searching databases provided by Web of Science. All documents published on vitiligo literature between 1975 and 2017 were included. We performed correlation analyses between productivity and demographical and economical features of the countries publishing vitiligo articles. Results: A total of 7187 documents were detected and 72.2% of which was original article. The peak year for publication number by year was 2016 with 528 articles and the highest number of citations was reported in 2017. The USA was the leading country by total publication number (24.82%) followed by the United Kingdom (UK), India, China, and Italy (10.91%, 8.64%, 7.54%, and 6.87% respectively). Estonia was found to be the most productive country of vitiligo literature (13.01) followed by Netherlands, the UK, and Switzerland (12.64, 11.78, and 9.25, respectively). We found a high correlation between GDP per capita and the productivity of the countries (r = 0.732,P < 0.001). Conclusion: As revealed in our study, although vitiligo occurs worldwide, developed countries dominated vitiligo literature. Researchers from developing and least-developed countries should be encouraged and supported to perform novel vitiligo studies. [ABSTRACT FROM AUTHOR]

The article discusses a study focusing on teledermatology research publication between 1975 and 2017 and its bibliometric evaluation. Topics discussed include the use of data from Thomson Reuters Web of Science in this study; the use of teledermatology keyword in the research; and the publication of teledermatology research in the U.S. and Great Britain.

Background/Objective Telemedicine and teledermatology literature has a limited number of bibliometrics reports. We aimed to analyze telemedicine and teledermatology literature using the Institute for Scientific Information Web of Science database. Methods The statistical analysis of the documents published during 1980–2013 was performed. We also analyzed the correlations between economical productivities, humanity index, and technological advancement levels and performances of the countries in both fields. Results The USA ranked first in the telemedicine field with 3204 publications and 33.8% of the world production followed by the UK and Germany. In the teledermatology field, the USA was the first country again with 206 papers (36%) followed by the UK and Australia (104 and 50 papers, respectively). The most productive countries in telemedicine were Cyprus (30.03), Norway (28.19), and Australia (19.61). Austria ranked first (4.94) in terms of productivity in teledermatology followed by Norway (3.13), New Zealand (2.43), and Australia (2.13). A high correlation was found between number of publications and 2013 gross domestic product values of 60 countries ( r = 0.804, p < 0.001 for telemedicine and r = 0.721, p < 0.001 for teledermatology). A high correlation was detected between the number of telemedicine publications and gross domestic product per hour worked ( r = 0.712, p < 0.001) although moderate correlation was measured in teledermatology field ( r = 0.558, p < 0.05). We found a significant correlation between number of publications and human development index ( r = 0.779, p < 0.001 for telemedicine and r = 0.767, p < 0.001 for teledermatology). Conclusion Most items have been published from high-income, developed countries. Thus the physicians in undeveloped and developing countries, in which telemedicine and teledermatology applications are crucial to deliver medical care and services, should be encouraged to perform novel studies.
