Background
Mycetoma is a neglected tropical disease that attracts little attention in regard to research and publications and hence this study was undertaken to determine the trends and global scientific research output in mycetoma-related fields.
Methods
Mycetoma data were retrieved from the Web of Science (WoS) and Scopus databases. The MeSH Browser was used to extract relevant keywords. Biblioshiny software (R-studio cloud), VOSviewer v. 1.6.6 and SPSS software were used for data management.
Results
Research trends on mycetoma increased globally from 1999 to 2020. The results were 404 documents (4444 citations) in WoS and 513 documents (5709 citations) in Scopus, and the average number of citations per article was 11 in WoS and 11.13 in Scopus. There was a significant association between the total number of citations and the total citations per year in both WoS (r=0.833, p<0.0001) and Scopus (r=0.926, p<0.0001). Sudan, India, the Netherlands and Mexico were the top-ranking productive countries for mycetoma publications in WoS, while India, the USA and Mexico were the top-ranking countries in Scopus. Articles on mycetoma were mainly published in PLoS Neglected Tropical Diseases, the International Journal of Dermatology and the Journal of Clinical Microbiology. A. H. Fahal from the Mycetoma Research Centre, University of Khartoum, Sudan, had the highest number of citations in mycetoma research during 1999–2020, followed by W. W. J. van de Sande from the Erasmus Medical Centre, University of Rotterdam, the Netherlands, during 2003–2020.
Conclusion
The analysis provides insight into a global overview of Mycetoma research. In addition, the analysis holds a better understanding of the development trends that have emerged in Mycetoma over the past 21 years, which can also offer a scientific reference for future research.
Highlights
Volvulus is a common cause of large bowel obstruction but its metachronous occurrence is an extreme rarity.
Metachronous transverse colonic volvulus should be eliminated as a differential diagnosis.
Gangrenous bowel is a life threatening condition and should be dealt with as an emergency situation with the adequate procedure.
The elective surgical resection should follow optimization of the general condition and set-up.
The ongoing pandemic of novel coronavirus disease, COVID19, which first reported in Wuhan, China, inDecember 2019, [1] and caused by severe acute respiratory syndrome coronavirus 2 (SARSCoV2) has resulted to more than 6,881,352 confirmed cases in the world, and 399,895 global deaths, as reported in 8:36am CEST, 8 June 2020. [2] It has been reported that the primary spread of COVID-19 via human transmission is during close contact, most often through small droplets spread by coughing, sneezing, and talking. [3] Researchers and health experts have discovered that wearing of appropriate face masks can significantly reduce the transmission up to the 75%.
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.
