Voluntary ambulation using voluntary upper limb muscle activity and Hybrid Assistive Limb® (HAL®) in a patient with complete paraplegia due to chronic spinal cord injury: A case report

Context: We sought to describe our experience with the Hybrid Assistive Limb® (HAL®) for active knee extension and voluntary ambulation with remaining muscle activity in a patient with complete paraplegia after spinal cord injury.

Findings: A 30-year-old man with complete paraplegia used the HAL® for 1 month (10 sessions) using his remaining muscle activity, including hip flexor and upper limb activity. Electromyography was used to evaluate muscle activity of the gluteus maximus, tensor fascia lata, quadriceps femoris, and hamstring muscles in synchronization with the Vicon motion capture system. A HAL® session included a knee extension session with the hip flexor and voluntary gait with upper limb activity. After using the HAL® for one month, the patient’s manual muscle hip flexor scores improved from 1/5 to 2/5 for the right and from 2/5 to 3/5 for the left knee, and from 0/5 to 1/5 for the extension of both knees.

Conclusion/clinical relevance: Knee extension sessions with HAL®, and hip flexor and upper-limb-triggered HAL® ambulation seem a safe and feasible option in a patient with complete paraplegia due to spinal cord injury.     

外伤性截瘫合并耳聋11例临床分析

初步分析了11例外伤性截瘫合并耳聋患者,指出外伤性截瘫多有慢性肾功能不全、肾性贫血等并发症。这些并发症对耳聋的发生有一定的影响,但长时间或反复使用耳毒性药物是一个不可忽视的重要因素。作者对此提出了预防耳聋的一些具体措施,可供临床参考或借鉴。

Acute transverse myelitis in the emergency department: A case report and review of the literature

Acute transverse myelitis (ATM) is a neurologic condition that presents with bilateral lower extremity weakness and sensory loss associated with bowel and bladder dysfunction. Whereas the time of onset may be hours to days, the time to either partial or complete recovery may require months. The etiology is varied and may be idiopathic. Laboratory and radiographic evaluation may be nonrevealing. Corticosteriods have been used for treatment, but their efficacy is controversial. As illustrated by this case report, the essential aspect of the initial management of ATM is the elimination of potentially treatable causes.

Epidural abscess following epidural steroid and local anaesthetic injection

Epidural abscess is a well-recognised but rare complication of epidural catheter placement. We have found only five previous reports of epidural abscess from noncatheter-related administration of steroids and/or local anaesthetic. We describe a further case which led to critical illness and emphasise the association between diabetes mellitus and epidural infection.     

截瘫患者血红蛋白水平的10年回顾性分析

通过对97例截瘫住院患者连续10年的Hb测定结果进行回顾性分组研究,结果表明,无并发症组10年中Hb分布较一致,其均值与正常人比较无显著性差异(P>0.05),但12.3％的病例Hb水平低于正常人下限;当截瘫并发泌尿系感染、尿毒症或难治性褥疮等病症时,则导致Hb水平的降低。提出Hb测定结果,可做为在整体水平上观察截瘫患者的治疗及康复效果的指标。     

骨髓间质干细胞和脑源性神经营养因子联合应用促进兔脊髓外伤性截瘫的修复

目的:观察骨髓间质干细胞(bone m arrow strom a cells,BM SCs)和脑源性神经营养因子(brain derived neurotrophic factor,BD N F)联合应用对兔脊髓外伤性截瘫结构和功能修复的影响,以寻求建立一种更有效的治疗脊髓外伤性截瘫的疗法。方法:采用改良A llen打击法建立兔脊髓外伤性截瘫的模型,模型建立成功后观察3d再分别行注射生理盐水(对照组)、BM SCs、BD N F和BM SCs BD N F干预。脊髓损伤移植后1、3、5周进行改良Tarlov评分及CSEP评测,5周观察脊髓结构的变化。结果:与BM SCs组、BD N F组相比,移植后第5周,BM SCs BD N F联合移植组脊髓损伤处结构恢复较好,第3周、5周后,BM SCs BD N F组的CSEP和改良Tarlov评分亦明显好于BM SCs组和BD N F组(P<0.01)。结论:BM SCs和BD N F联合移植对急性脊髓外伤性截瘫的结构和功能有更好的修复作用。     

A novel missense mutation (I344K) in the SPG4gene in a Korean family with autosomal-dominant hereditary spastic paraplegia

 Hereditary spastic paraplegia (HSP) is a group of clinically and genetically heterogeneous neurodegenerative disorders characterized by slowly progressive spasticity and weakness of the lower extremities. Among eight loci linked with autosomal-dominant (AD)-HSP, the SPG4 locus on chromosome 2p22 accounts for about 40% of all patients. Recently, mutations in a new member of the AAA protein family, called spastin, have been identified as responsible for SPG4-linked AD-HSP. Here, we describe a novel missense mutation (c.1031T>A; I344K) in exon 7 of the SPG4 gene identified in a Korean family with typical clinical features of pure AD-HSP. The mutation affects the third amino acid of the highly conserved AAA cassette domain, which is the most fore part of the domain altered by a missense mutation reported so far. Clinical presentations of affected individuals carrying the I344K mutation were not different from those of pure AD-HSP with SPG4 mutations reported previously. However, it is noteworthy that neither urinary dysfunction nor involvement of upper extremities was noticed in this family. To our knowledge, this is the first report of genetically confirmed AD-HSP in Korea. Received: February 20, 2002 / Accepted: May 21, 2002     

一个遗传性痉挛性截瘫家系的临床特点与spastin基因突变分析

目的探讨遗传性痉挛性截瘫(hereditary spastic paraplegia,HSP)一家系的临床特点及其与spastin基因突变关系。方法对整个家系进行详细的临床检查,先证者和家系内另两例患者进行了肌电图检查,先证者还进行了胸髓核磁共振检查。应用聚合酶链反应结合DNA序列分析方法,检测该家系中先证者和其父亲spastin基因的突变情况。结果家族中所有患者具有遗传性痉挛性截瘫的典型表现,先证者胸髓核磁共振成像显示胸髓明显萎缩,PCR-DNA序列分析患者spastin基因的17个外显子均未发现有异常的突变。结论该HSP家系的患者具有典型的临床表现,并非spastin基因外显子突变所致。
