概括
通过将标准生物标记物如血清C反应蛋白 (CRP) 和突白细胞 (WBC) 与新型标记物如素-3 (PTX3) 结合起来,可以改善感染性关节炎的诊断. 这种方法提高了这种骨科紧急情况的诊断准确性.
科学领域:
- 整形外科 整形外科 整形外科
- 临床化学 临床化学
- 免疫学 免疫学 免疫学
背景情况:
- 败血性关节炎是一个关键的骨科紧急情况,需要及时诊断.
- 目前的诊断标准和败血性关节炎的最佳生物标志物尚未完全确定.
- 该研究调查了既有和新生物标志物的实用性,以区分败血性和非败血性关节炎.
研究的目的:
- 为了评估血清C反应蛋白 (CRP),突白细胞 (WBC),素-3 (PTX3),介质素-6 (IL-6) 和前素的诊断性能.
- 为了比较单个生物标志物及其组合的诊断准确性.
- 确定适合排除或确认败血性关节炎的生物标志物.
主要方法:
- 来自31名接受关节切除术的患者的血清和突液样本的分析.
- 将患者分为败血性和非败血性关节炎组的分类.
- 用曲线下的面积 (AUC),准确性,灵敏度,特异性,正预测值 (PPV) 和负预测值 (NPV) 来评估诊断性能.
主要成果:
- 在单个生物标志物中,同胞白细胞表现为最高的诊断性能 (AUC=0.837).
- 结合血清CRP和突白细胞,实现了100%的灵敏度和NPV.
- 将新生物标志物 (PTX3,IL-6,前素) 添加到血清CRP和突白细胞中,进一步改善了AUC至0.887,保持了100%的灵敏度和NPV. PTX3在排除问题上表现出色,而前素在确认问题上表现出很高的特异性.
结论:
- 血清CRP和突白血球对性关节炎的诊断至关重要.
- 将它们与PTX3,IL-6和普雷塞普辛结合,可以提高诊断准确度.
- 建议采用量身定制的生物标志物策略,使用PTX3进行排除和前素进行确认.

Acute Pyelonephritis II: Diagnostic Studies and Management
40
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
