BACKGROUND
The lack of standardized nomenclature for atopic dermatitis (AD) creates challenges for scientific communication, patient education, and advocacy.
OBJECTIVE
We sought to determine the relative popularity of the terms eczema, AD, and atopic eczema (AE) using global search engine volumes.
METHODS
A retrospective analysis of average monthly search volumes from 2014 to 2016 of Google, Bing/Yahoo, and Baidu was performed for eczema, AD, and AE in English and 37 other languages. Google Trends was used to determine the relative search popularity of each term from 2006 to 2016 in English and the top foreign languages, German, Turkish, Russian, and Japanese.
RESULTS
Overall, eczema accounted for 1.5 million monthly searches (84%) compared with 247 000 searches for AD (14%) and 44 000 searches for AE (2%). For English language, eczema accounted for 93% of searches compared with 6% for AD and 1% for AE. Search popularity for eczema increased from 2006 to 2016 but remained stable for AD and AE.
CONCLUSIONS
Given the ambiguity of the term eczema, we recommend the universal use of the next most popular term, AD.
背景
特应性皮炎（AD）缺乏标准化命名法，给科学交流、患者教育及宣传工作带来了挑战。
目的
我们试图通过全球搜索引擎搜索量来确定湿疹、特应性皮炎（AD）和特应性湿疹（AE）这几个术语的相对流行程度。
方法
对2014年至2016年期间谷歌、必应/雅虎和百度在英语及其他37种语言中关于湿疹、AD和AE的月平均搜索量进行回顾性分析。利用谷歌趋势确定2006年至2016年期间每个术语在英语以及德语、土耳其语、俄语和日语这几种主要外语中的相对搜索流行程度。
结果
总体而言，湿疹每月搜索量为150万次（84%），相比之下，AD为24.7万次（14%），AE为4.4万次（2%）。在英语中，湿疹占搜索量的93%，AD占6%，AE占1%。从2006年到2016年，湿疹的搜索流行度有所上升，但AD和AE的搜索流行度保持稳定。
结论
鉴于湿疹这一术语存在歧义，我们建议普遍使用次流行程度最高的术语AD。
