Top 100 Highly Cited Articles on Rhinoplasty between 2001 and 2020: A Bibliometric and Visualized Analysis.

BACKGROUND: The authors performed a bibliometric and visualized analysis of the top 100 highly cited articles in rhinoplasty published between 2001 and 2020, to provide researchers with the present research status and the potential directions. METHODS: The authors obtained data from the Web of Science Core Collection on April 7, 2021. Quantitative and qualitative analyses were performed using the Web of Science. Collaboration and keyword analyses were performed using VOSviewer software. RESULTS: The top 100 highly cited articles included 86 original research articles and 14 reviews. The average total citations was 77 (range, 50 to 202). The article with 202 citations was published by Toriumi in 2006 and was the most influential reference. The most common level of evidence was level IV ( n = 24). Only five articles had a level of evidence of I. The top 100 articles were published in 24 journals. Plastic and Reconstructive Surgery published 49 articles with 4013 citations. The United States published the most highly cited articles. The University of Texas System published 16 articles with 1166 citations. R. J. Rohrich published 14 articles with 1025 total citations. "Cleft lip and palate," "FACE-Q," "Functional Rhinoplasty Outcome Inventory 17," "NOSE scale" (Nasal Obstruction Symptom Evaluation scale), "quality-of-life," "questionnaire," and "RHINO scale" (Rhinoplasty Health Inventory and Nasal Outcomes scale) were important keywords. CONCLUSIONS: Plastic and Reconstructive Surgery was the most influential journal, most research was reported from the United States, and the University of Texas System published the most highly cited article. R. J. Rohrich, R. K. Daniel, and B. Guyuron were the most prolific and influential authors. Global cooperation in rhinoplasty requires further strengthening.

NPHS2 variation in sporadic focal segmental glomerulosclerosis.

Mutations in NPHS2, the gene that encodes podocin, are well-established causes of both familial and sporadic steroid-resistant focal segmental glomerulosclerosis (FSGS) in the pediatric population, but have not been well-characterized in late-onset disease. To investigate the role of NPHS2 polymorphisms in sporadic cases of late-onset FSGS, we studied 377 biopsy-confirmed FSGS cases and 919 controls. We identified 18 single nucleotide polymorphisms (SNPs) by resequencing a subgroup of cases and controls, and subsequently genotyped African-American and European-American cases and controls for five missense SNPs, three SNPs within introns, and four SNPs in the 3' untranslated region. No homozygotes or compound heterozygotes were observed for any missense mutation. R138Q carriers were more frequent among FSGS cases relative to controls (OR = 4.9, P = 0.06), but heterozygosity for the other four missense mutations was equally distributed among FSGS cases and controls. Finally, a common haplotype of noncoding SNPs carried by 20% of African-Americans, but not observed in European-Americans, was strongly associated with a 50% reduction in risk for sporadic FSGS (OR = 0.5, P = 0.001). These results indicate that genetic variation or mutation of NPHS2 may play a role in late-onset sporadic FSGS.
