Abstract
Botulinum neurotoxin serotype A (BoNT-A) has several therapeutic indications such as spasticity and dystonia. Although its use is generally considered safe, a systemic diffusion can lead to systemic complications, and a botulism-like syndrome can occur after intramuscular injections. Herein, two adult cases who developed general muscle weakness after a BoNT-A intramuscular injection are reported. Both presented with a progressive decrement on low-frequency (LF) repetitive nerve stimulation (RNS). It is suggested that a progressive decrement on LF-RNS in muscles distant from the injection site strongly supports the diagnosis of iatrogenic botulism.
血清 A 型肉毒杆菌神经毒素(BoNT-A)具有多种治疗适应症,如痉挛和肌张力障碍。尽管人们普遍认为其使用是安全的,但全身扩散可能导致全身并发症,肌肉注射后可能出现肉毒中毒样综合征。本文报告了两例在肌肉注射 BoNT-A 后出现全身肌无力的成人病例。两人在接受低频(LF)重复神经刺激(RNS)后均出现进行性肌力下降。研究认为,远离注射部位的肌肉在接受低频重复神经刺激(LF-RNS)时出现进行性减弱,可有力地支持先天性肉毒中毒的诊断。
期刊介绍:
Neurophysiologie Clinique / Clinical Neurophysiology (NCCN) is the official organ of the French Society of Clinical Neurophysiology (SNCLF). This journal is published 6 times a year, and is aimed at an international readership, with articles written in English. These can take the form of original research papers, comprehensive review articles, viewpoints, short communications, technical notes, editorials or letters to the Editor. The theme is the neurophysiological investigation of central or peripheral nervous system or muscle in healthy humans or patients. The journal focuses on key areas of clinical neurophysiology: electro- or magneto-encephalography, evoked potentials of all modalities, electroneuromyography, sleep, pain, posture, balance, motor control, autonomic nervous system, cognition, invasive and non-invasive neuromodulation, signal processing, bio-engineering, functional imaging.
