Rome Ⅰ, the first edition was published in 1994, with symptom-based diagnostic criteria for FGIDs. These criteria began to change the diagnostic approach to F-GIDs, and no longer considered ＂diagnoses of exclusion＂ but rather ＂diagnoses of inclusion＂. Rome Ⅱ, the second edition published in 2000, resulted from the continual process of analyzing new scientific and clinical evidence in the study of F-GIDs. Rome Ⅱ, diagnostic criteria for irritable bowel syndrome （IBS）, was extended with a focus on the frequency of symptoms occurring twelve weeks （not necessarily consecutive weeks） within twelve months. ROlE Ⅲ, the third edition, conservative one, was published in September 2006, with changes made only where there is good evidence to do so. Some of the differences between Rome Ⅱ and Rome Ⅲ criteria are highlighted in this issue.展开更多

This study was designed to investigate the association between CS and the grading score using the lens opacities classification system （LOCS） III as well as the association between CS and visual acuity （VA） in nuclear or cortical age-related cataract （ARC） patients. Methods A total of 270 eyes with ARC and 30 control eyes were divided into nuclear opacity （NO）, nuclear color （NC）, cortical cataract （C） based on LOCS II1. The CS values measured at all spatial frequencies under photopic and glare conditions that resulted in contrast sensitivity function （CSF） were evaluated, and LogMAR VA was tested with the Early Treatment Diabetic Retinopathy Study （ETDRS） chart. The correlation between CSF and LOCS III grading scores, and between CSF and LogMAR VA were analyzed. Results Compared to the controls, CSF of the nuclear or cortical ARC significantly declined. There are significant correlation between CSF and LogMAR VA, and between CSF and LOCS III grading scores. Compared to the VA, a stronger correlation existed between CSF and LOCS III grading score than that of LogMAR VA and LOCS III grading score. CS at some spatial frequencies is significantly influenced with LOCS III grading score. Conclusions CSF significantly declined with the increasing ARC grading scores. Comparing to VA, CSF reflected the severity of cataract more comprehensively. CS at low spatial frequency is significantly influenced by ARC. Therefore, CS is more precise than VA in assessing the visual function of ARC patients.展开更多

文摘目的:研究慢性偏头痛(chronic migraine,CM)的临床特征,并对国际头痛疾病分类第3版试行版(International Classification of Headache Disorders,3rd Edition,beta version,ICHD-Ⅲbeta)及专家共识版(Expert Opinion criteria,EOc)CM的诊断标准进行临床实践测试。方法:回顾性分析重庆医科大学附属第一医院神经内科头痛门诊2014年6月至2016年6月CM患者的人口学特征及临床特征,并对ICHD-Ⅲbeta及EOc版CM诊断标准进行临床实践测试分析。结果:共纳入236例CM患者,165例(69.9%)患者合并药物过度使用,仅2例(0.8%)患者使用曲普坦类,无患者使用麦角胺类。CM患者的偏头痛亚型中最常见的是无先兆偏头痛(migraine without aura,MO;70.3%),其次为可能性偏头痛(probable migraine,PM;26.3%)和先兆偏头痛(migraine with aura,MA;3.4%)。236例患者均满足EOc版标准,仅167例(70.8%)满足ICHD-Ⅲbeta版CM标准。69例不符合ICHD-Ⅲbeta标准的患者中,62例为不典型偏头痛发作,符合PM,7例为有典型偏头痛发作但既往发作少于5次。结论:CM患者常合并药物过度使用,但偏头痛特异性止痛药曲普坦及麦角胺类使用较少。EOc版CM诊断标准更符合中国CM患者的实际情况,可能更利于在临床中应用。
