- 免疫学 免疫学 免疫学
背景情况:
- 狼性炎 (LN) 是系统性红斑狼 (SLE) 的严重并发症.
- 脏活检是诊断的黄金标准,但具有侵入性.
- 本研究探讨了非侵入性对比增强超声波 (CEUS) 参数,以区分LN类型.
研究的目的:
- 评估定量CEUS参数,以非侵入性预测增殖性与非增殖性狼性炎.
- 为了比较CEUS发现与LN患者的活检结果.
- 确定可帮助临床决策的CEUS参数,用于LN管理.
主要方法:
- 在活检前接受CEUS的58名经活检确认的LN患者的回顾性分析.
- 分类为增殖性 (38例) 和非增殖性 (20例) 的LN.
- 从时间强度曲线 (TIC) 分析临床数据,常规超声波和CEUS定量参数,使用后勤回归和ROC分析.
主要成果:
- 患有增殖性LN的患者显示,到峰值的绝对时间 (∆TTP),半下降时间 (DT/2) 和曲线下的TIC面积 (TIC-AUC) 值 (P < .05) 显著更高.
- 鉴定出TIC-AUC和抗dsDNA抗体是扩散性LN的独立预测因素.
- ROC分析显示,TIC-AUC的AUC达到0.810 (灵敏度为68.8%,特异性为84.6%),表现优于抗dsDNA (AUC为0.745).
结论:

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Nephrotic Syndrome II : Assessment and Medical Management
187
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
