BACKGROUND

Atopic eczema is a common and distressing disease. This study aims to review PubMed indexed research statistics on atopic eczema over a-10 year period to investigate the clinical relevance and research interest about this disease.

METHODS

PubMed (a service of the U.S. National Library of Medicine) was searched for the terms "atopic dermatitis" and "eczema", with limits activated (Humans, Clinical Trial, Meta-Analysis, Randomized Controlled Trial, English, published in the last 10 years), and editorials, letters, practice guidelines, reviews, and animal studies excluded. Journal impact factor (IF) is in accordance with Journal Citation Report (JCR) 2009, a product of Thomson ISI (Institute for Scientific Information).

RESULTS

A total of 890 articles were retrieved. Taking out publications that were irrelevant and those without an impact factor, 729 articles were obtained. These articles were grouped into dermatology (n = 337, mean IF: 3.01), allergy/immunology (n = 215, mean IF: 4.89), pediatrics (n = 118, mean IF: 2.53) and miscellaneous subject categories (n = 142, mean IF: 5.10). The impact factors were highest in the miscellaneous category (p = 0.0001), which includes such prestigious journals as the New England journal of Medicine (n = 1, IF: 47.05), the Lancet (n = 4, IF: 30.76) and BMJ (n = 6, IF: 13.66). There was no publication in any family medicine or general practice journal. The British Journal of Dermatology (n = 78), Pediatric Allergy and Immunology (n = 49) and Journal of Allergy and Clinical Immunology (n = 46) had the highest number of publications on the subject. Atopic eczema ranked higher in impact factors in allergy/immunology although more publications appeared in the dermatology category.

CONCLUSIONS

Atopic eczema is a multidisciplinary disease. Its clinical relevance and research interests are definitely beyond that of a mere cutaneous disease. Investigators may consider allergy/immunology and miscellaneous journal categories for higher impact of their research.
