概括
围膜膜炎和纤维化 (PDIF) 在肌肉炎相关的间歇性肺病 (M-ILD) 中很常见,通常与抗Jo抗体有关. 早期识别PDIF可能有助于M-ILD的诊断和管理,但似乎不会影响疾病的进展.
科学领域:
- 放射学 放射学是一门学科.
- 肺部病理学 肺部病理学
- 类风湿病学 类风湿病学
背景情况:
- 周周膜炎和纤维化 (PDIF) 是一种已知的放射性特征,在患有肌炎相关的间歇性肺病 (M-ILD) 的患者中.
- 在M-ILD中PDIF的精确定义和临床意义需要进一步阐明.
研究的目的:
- 为PDIF建立正式的高分辨率计算机断层扫描 (HRCT) 标准.
- 研究PDIF与M-ILD患者的临床,血清和成像特征之间的关联.
主要方法:
- 对46名M-ILD患者和169个HRCT扫描的回顾性审查.
- 三位胸部放射科医生制定了PDIF标准.
- 两个放射科医生对PDIF扫描的独立评估,与临床和血清学数据相关联.
主要成果:
- 在28.2%的患者和18.9%的扫描中存在PDIF,经常出现早期并持久.
- PDIF与抗Jo-1和抗Ro52抗体和并发性肌肉炎有关.
- 呼吸障碍在PDIF患者中普遍存在;然而,肺功能趋势 (FVC,DLCO) 与没有PDIF患者没有显著差异.
结论:
- PDIF是M-ILD的常见发现,特别与抗合成酶综合征有关.
- 早期发现PDIF可能有助于M-ILD的诊断和管理.
- PDIF似乎与疾病进展无关,尽管对更广泛的炎症性ILDs进行进一步研究是有必要的.

Pericarditis I: Introduction
301
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Pericarditis II: Clinical Features and Diagnostic Tests
270
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
