We compared the P13 latency of VEMP and the R1, R2, R2’ latency of the blink reflex in stroke patients. Statistical analysis was conducted using the Fisher exact test and independent t-test, with a p-value < 0.05 indicating statistical significance.Results: In 29 stroke patients, excluding those with bilateral lesions, the VEMP and the blink test did not show a statistically significant relationship (p = 0.2701). In all 34 stroke patients participating in the study, including those with bilateral lesions, R2’ mean showed a statistically significant difference (p = 0.0081) according to the presence of normal or abnormal VEMP. Conclusion: R2’ of the blink reflex passes through more neural pathways and polysynaptic pathways than R1 and R2; therefore, it showed a more prominent difference between the normal and abnormal VEMP groups.","PeriodicalId":440658,"journal":{"name":"Journal of Electrodiagnosis and Neuromuscular Diseases","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123803525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lumbar plexus, a complex neural network formed by divisions of the first four lumbar roots, penetrates the psoas muscle before it exits the pelvis. Owing to their anatomical proximity, neoplasms in the vicinity of the psoas muscle may involve the lumbar plexus. We report a case of postoperative lumbar plexopathy involving the posterior divisions of the lumbar plexus, following the resection of a recurrent retroperitoneal liposarcoma located in the dorsal aspect of the psoas muscle. A 50-year-old man visited a rehabilitation clinic for an evaluation of proximal weakness of the unilateral lower extremity after resection of a recurrent liposarcoma of the left psoas muscle. Physical examination showed weakness of left hip flexion and knee extension accompanied by sensory loss in the left anteromedial thigh and the medial lower leg. An electrophysiological study revealed left lumbar plexopathy with selective involvement of the posterior divisions of the lumbar plexus. The patient could walk independently without a walking aid on level surfaces while he underwent exercise therapy. A comprehensive evaluation, including a physical examination, the use of imaging modalities such as computed tomography for anatomical characterization, and electrophysiological studies, is important for accurate diagnosis.","PeriodicalId":440658,"journal":{"name":"Journal of Electrodiagnosis and Neuromuscular Diseases","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128138582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 17-year-old female patient presented with left upper extremity swelling and pain after inoculation with the BNT162b2 vaccine in the left deltoid muscle. Contrast-enhanced brachial plexus magnetic resonance imaging revealed severe swelling of the left axillary and subclavian lymph nodes, which lie immediately above the subclavian vein. An electrodiagnostic study revealed left brachial plexopathy, mainly involving the lower trunk with mixed demyelinating and axonal injury.

CMT can be classified into demyelinating, intermediate, or axonal neuropathy based on clinical, histopathological, and electrophysiological findings. Approximately 140 genes have been reported to be associated with CMT. Mutations in the myelin protein zero (MPZ), ganglioside-induced differentiation related protein 1 (GDAP1), and neurofilament light-chain polypeptide gene (NEFL) genes have been reported to cause all three types of CMT, which is noteworthy because most CMT-related genes cause a single type of neuropathy (either demyelinating or axonal). In contrast, it remains unclear why these genes cause several types of CMT. CMT is presently incurable; however, ongoing attempts to treat CMT with various drugs and dietary supplements have increased the importance of an exact genetic diagnosis for precision medicine. Therefore, it is important to identify the causative mutations and compare the associated clinical characteristics. Taken together, a comparison of causative mutations and clinical features of patients with MPZ, GDAP1, and NEFL mutations will be the first step in understanding how different types of CMT are caused, and will enable a molecular genetic diagnosis. In this review, we describe the clinical, electrophysiological, and genetic characteristics of MPZ-, GDAP1-, and NEFL-related CMT.","PeriodicalId":440658,"journal":{"name":"Journal of Electrodiagnosis and Neuromuscular Diseases","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125499412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motor studies, including segmental and inching tests, and sensory NCS were performed. The 5-point severity score was evaluated based on the signal change and swelling in the fat-suppressed T2 weighted sequence. The findings of MRI and NCS were grouped into 3 categories. The Spearman rank test was used to evaluate correlations between the severity score on MRI and electrodiagnostic parameters.Results:The locations of the lesions on MRI and NCS were correlated in 20 of the 46 patients with UNE, while the other 20 patients had no correlations. Six patients who could not be categorized according to the location showed various findings. The severity score based on MRI showed significant negative correlations with amplitude on the segmental study (r = -0.423, p = 0.002) and the inching study (r = -0.456, p = 0.002), and with conduction velocity in the segmental study (r = -0.526, p < 0.001) and the inching study (r = -0.548, p < 0.001).Conclusion Electrodiagnostic outcomes had negative correlations with the severity score, reflecting the structural changes seen on MRI.

Some cases related to subacute combined degeneration or myeloneuropathy after N2O abuse have been reported. However, isolated peripheral polyneuropathy without spinal cord involvement has rarely been reported in South Korea. We describe a 29-year-old woman who had inhaled “happy balloons” daily (1,000 balloons/day) for recreational purposes over 3-month period, and presented with acute symmetrical hypoesthesia, paresthesia, and motor weakness on the bilateral lower limbs. Serologic tests showed megaloblastic anemia and vitamin B12 deficiency. Magnetic resonance imaging of the brain and spine showed no abnormalities. An electrodiagnostic study confirmed lower limb-dominant axonal sensorimotor polyneuropathy due to vitamin B12 deficiency from N2O abuse. The patient was treated with intramuscular vitamin B12 replacement. A follow-up electrodiagnostic study 4 months after the initial study showed only partial improvement. Despite the legal efforts of the Korean government to ban the use of N2O other than for medical purposes, cases of complications from its abuse are on the rise, especially among young adults. Physicians should recognize the strong possibility of N2O abuse as an underlying cause of vitamin B12 responsive polyneuropathy with or without spinal cord involvement.","PeriodicalId":440658,"journal":{"name":"Journal of Electrodiagnosis and Neuromuscular Diseases","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117115367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common clinical finding was proximal muscle weakness in all 5 patients, followed by spinal scoliosis and respiratory distress in 4 patients and delayed motor development in 2 patients. Other uncommon clinical findings were winged scapula in one patient and cardiomegaly in one patient. Magnetic resonance imaging of muscles revealed that fatty replacement was predominant in the paraspinal muscles, adductors, semimembranosus, semitendinosus, long head of the biceps femoris, and medial gastrocnemius. Muscle biopsies in 2 patients showed type 1 predominance and multiple eccentric cores within the fibers. We identified 5 pathogenic variants of SELENON.
