概括
克罗恩病患者的psoas肌肉的明显扩散系数 (ADC) 在不复杂和严格的疾病患者中较低. 这一发现表明ADC可能作为CD肌肉变化的成像生物标志物.
科学领域:
- 胃肠病学 胃肠病学
- 放射学 放射学是一门学科.
- 生物标志物 生物标志物
背景情况:
- 克罗恩氏病 (CD) 是一种慢性炎症性肠病.
- 评估疾病活动及其对骨肌肉的影响对于患者管理至关重要.
- 肌肌肉的变化可能反映了CD中的全身炎症.
研究的目的:
- 评估psoas肌肉明显扩散系数 (ADC) 和psoas肌肉指数 (PMI) 与克罗恩病活动和分类之间的关联.
- 确定ADC和PMI是否可以作为CD肌肉参与的成像生物标志物.
主要方法:
- 对88名克罗恩病患者进行磁共振肠道扫描的回顾分析.
- 基于蒙特利尔分类 (B1,B2,B3) 和疾病活性 (马里亚,爬行脂肪) 的患者分类.
- 在L3脊椎水平测量psoas肌肉的ADC和PMI.
主要成果:
- 与对照组相比,在无并发症 (B1) 和并发症 (B2+B3) 的CD中观察到较低的ADC值 (p=0.02).
- 患有严格疾病 (B2) 的患者的ADC显著低于非严格疾病的患者 (p=0.01).
- 与透性疾病相比,非透性疾病的PMI较高 (p=0.10),尽管在统计学上并不显著. 根据MaRIA得分或爬行脂肪的存在,没有发现ADC或PMI的显著差异.
结论:
- 克罗恩病患者的psoas肌肉的明显扩散系数 (ADC) 显著降低,特别是那些没有并发症和严格的疾病患者.
- ADC显示了与克罗恩病相关的神经病变的成像生物标志物的潜力.
- 需要进一步的研究来探索ADC在监测CD进展和治疗反应方面的临床实用性.

Appendicitis-I: Introduction
128
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Assessment of the Rectum and Anus
208
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
