概括

电肌图 (EMG) 经常显示出异常,特别是在患有异常性炎症性肌病 (IIM) 的患者中,特别是纤维化潜力和积极的尖波 (Fib/PSW). 这些发现对于诊断IIM至关重要,即使在不符合全部分类标准的情况下也是如此.

科学领域:

类风湿病学类风湿病学
神经学神经学
临床电生理学临床电生理学

背景情况:

异常性炎症性肌肉病变 (IIM) 的诊断是使用欧洲反风湿联盟/美国风湿学会 (EULAR/ACR) 标准进行的.
电肌图 (EMG) 对于诊断IIM至关重要,但其与EULAR/ACR标准相关的发现需要进一步调查.

研究的目的:

在被诊断为IIM的患者中,确定特定EMG异常的频率,即纤维化潜力和正尖波 (Fib/PSW) 的频率.
在IIM的EULAR/ACR分类标准的背景下分析EMG发现.

主要方法:

对临床诊断为IIM的成年患者的临床和EMG记录的回顾性审查 (多质神经炎,皮质神经炎,氨基性皮质神经炎,包容性身体神经炎).
根据EULAR/ACR标准对患者进行分类.
在被招募的患者队列中调查Fib/PSW的频率.

主要成果:

在79名临床诊断为IIM的患者中,有75人符合确定的或可能的IIM标准.
在符合IIM标准的95%的患者中观察到动潜力和积极的尖波 (Fib/PSW).
在4名不符合足够的IIM概率标准的患者中也检测到Fib/PSW.

结论:

在根据IIM的EULAR/ACR标准分类的患者中,动潜力和正尖波 (Fib/PSW) 非常普遍.
电磁图谱的发现,特别是Fib/PSW,可以帮助检测IIM中的肌肉参与,包括在不完全满足分类标准的情况下.

Myasthenia Gravis: Diagnostic Tests

Myasthenia Gravis: Diagnostic Tests

Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Disorders of the Skeletal Muscle

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
