概括
爪视频毛囊镜 (NVC) 揭示了系统性硬化症 (SSc) 中明显的微血管损伤模式. 与有限的皮肤SSc (lcSSc) 相比,扩散皮肤SSc (dcSSc) 显示出更严重的毛细血管损失和晚期NVC变化.
科学领域:
- 类风湿病学 类风湿病学
- 皮肤病学 皮肤病学
- 微血管医学是一种微血管医学.
背景情况:
- 系统性硬化症 (SSc) 是一种多系统的自身免疫性疾病,其特点是微血管异常.
- 爪视频毛囊镜 (NVC) 是一种非侵入性技术,用于可视化爪毛细血管并评估微血管状况.
- 区分有限皮肤SSc (lcSSc) 和扩散皮肤SSc (dcSSc) 对于预后和管理至关重要.
研究的目的:
- 调查和区分在皮肤SSc有限 (lcSSc) 和皮肤SSc扩散 (dcSSc) 的患者中详细的指甲折视频毛囊镜 (NVC) 发现.
- 为了将NVC发现与疾病严重程度和系统性硬化症 (SSc) 的临床子集相关联.
主要方法:
- 招募了157名患者:100人患有lcSSc,27人患有dcSSc,30人患有初级雷诺现象 (pRP).
- 评估NVC SSc模式,绝对毛细血管数量 (每线性毫米),并得分为"早期"/"活跃"和"晚期"NVC状态.
- 评分包括毛细血管扩张,微型出血,巨型毛细血管,毛细血管密度,改变的微血管结构和异常的毛细血管形状.
主要成果:
- 在lcSSc,dcSSc和pRP组中发现绝对毛细血管数的显著差异 (p<0.001).
- dcSSc患者表现出明显更高的毛细血管数量损失和更高的"晚期"NVC状态得分,表明更严重的微血管损伤.
- 更高的Rodnan皮肤评分与毛细血管数量的减少和"晚期"NVC状态评分的增加相关 (p<0.001).
结论:
- 详细的NVC分析和评分对于区分lcSSc和dcSSc之间的微血管损伤严重程度至关重要.
- 这些发现强调了NVC在评估系统性硬化症亚型中的疾病严重程度和进展方面的实用性.

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
38
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

01:27Assessment of the Cardiovascular System III: Palpation
501
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
