    Brown-Sequard syndrome (BSS) is a unilateral cord injury characterised by an ipsilateral motor deficit with contralateral pain and temperature hypoaesthesia. Although there are a variety of causes, the majority of cases are generally of neoplastic origin or are traumatic in origin. We describe a rare cause of Brown-Sequard syndrome as a result of post-traumatic arachnoiditis. Magnetic resonance imaging with the use of thin-slice high-resolution constructive interference in steady state (CISS) and T2-weighted spin-echo sequence were used to demonstrate the cause and appearance of the lesion in the spinal canal and was useful in the assessment and management of the patient. This case illustrates the usefulness of the CISS sequence in MRI for elucidating arachnoiditis.

    BACKGROUND: Nurses are involved in delivering care for patients following acute traumatic spinal cord injury throughout the entire care journey. An injury of this type is significant for the individual and their family and can be challenging for nurses delivering care for patients with life changing injuries, especially for nurses new to this setting. There is a lack of research that examines the experience of nurses caring for these patients in the acute setting.

    METHOD: A hermeneutic phenomenological approach was used to understand the experience of nurses caring for patients in the acute setting who had sustained a traumatic spinal injury with associated neurological deficit. Using the phenomenological approach guided by the insight of Gadamer and Max Van Manen, participants with a broad range of experience were recruited and interviewed. The responses were transcribed into a text and subjected to hermeneutic analysis. Burnard's (1991) 14-step process and the hermeneutic approach were used to interpret and understand the phenomenon of interest.

    CONCLUSION: The study highlights the experience and challenges of providing care to these individuals. Although patients had significant physical disabilities and were often dependent physically, the nurses' concerns were directed more towards fulfilling their psychological needs. Nurses identified grieving patients and felt their role was to provide realistic hope to motivate them. They felt an internal tension regarding desensitisation towards their patients, but this was often an internal protective mechanism to deal with the significance of the events surrounding these patients. Nurses new to this setting took time to learn the routines and manage the unique challenges effectively. Caring for these patients gave the nurses the opportunity to understand their patients and their families, and appreciate that both groups will fluctuate in their behavior throughout the acute process, as they adjust to grief and loss.

    A severe epizootic of bovine malignant catarrh occurred from November 1976 until June 1977 in cattle at an agricultural institute in peninsular Malaysia. In a group of 82 Kedah-Kelantan cattle the morbidity rate was 47.6 per cent with a fatality rate of 89.7 per cent. In a group of 43 local Indian dairy cattle the morbidity rate was 23.3 per cent with a fatality rate of 100 per cent. Although evidence suggested that sheep acted as a common source of infection, the disease occurred in one animal which had no contact with sheep but had contact with infected cattle and carcases.

    Leg exercises through standing, cycling and walking with/without FES may be used to preserve lower limb muscle and bone health in persons with physical disability due to SCI. This study sought to examine the effectiveness of leg exercises on bone mineral density and muscle cross-sectional area based on their clinical efficacy in persons with SCI. Several literature databases were searched for potential eligible studies from the earliest return date to January 2022. The primary outcome targeted was the change in muscle mass/volume and bone mineral density as measured by CT, MRI and similar devices. Relevant studies indicated that persons with SCI that undertook FES- and frame-supported leg exercise exhibited better improvement in muscle and bone health preservation in comparison to those who were confined to frame-assisted leg exercise only. However, this observation is only valid for exercise initiated early (i.e., within 3 months after injury) and for ≥30 min/day for ≥ thrice a week and for up to 24 months or as long as desired and/or tolerable. Consequently, apart from the positive psychological effects on the users, leg exercise may reduce fracture rate and its effectiveness may be improved if augmented with FES.

    BACKGROUND: Excitotoxicity-induced in vivo injury models are vital to reflect the pathophysiological features of acute spinal cord injury (SCI) in humans. The duration and concentration of chemical treatment controls the extent of neuronal cell damage. The extent of injury is explained in relation to locomotor and behavioural activity. Several SCI in vivo methods have been reported and studied extensively, particularly contusion, compression, and transection models. These models depict similar pathophysiology to that in humans but are extremely expensive (contusion) and require expertise (compression). Chemical excitotoxicity-induced SCI models are simple and easy while producing similar clinical manifestations. The kainic acid (KA) excitotoxicity model is a convenient, low-cost, and highly reproducible animal model of SCI in the laboratory. The basic impactor approximately cost between 10,000 and 20,000 USD, while the kainic acid only cost between 300 and 500 USD, which is quite cheap as compared to traditional SCI method.

    METHODS: In this study, 0.05 mM KA was administered at dose of 10 µL/100 g body weight, at a rate of 10 µL/min, to induce spinal injury by intra-spinal injection between the T12 and T13 thoracic vertebrae. In this protocol, detailed description of a dorsal laminectomy was explained to expose the spinal cord, following intra-spinal kainic acid administration at desired location. The dose, rate and technique to administer kainic acid were explained extensively to reflect a successful paraplegia and spinal cord injury in rats. The postoperative care and complication post injury of paraplegic laboratory animals were also explained, and necessary requirements to overcome these complications were also described to help researcher.

    RESULTS: This injury model produced impaired hind limb locomotor function with mild seizure. Hence this protocol will help researchers to induce spinal cord injury in laboratories at extremely low cost and also will help to determine the necessary supplies, methods for producing SCI in rats and treatments designed to mitigate post-injury impairment.

    CONCLUSIONS: Kainic acid intra-spinal injection at the concentration of 0.05 mM, and rate 10 µL/min, is an effective method create spinal injury in rats, however more potent concentrations of kainic acid need to be studied in order to create severe spinal injuries.

    Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease of idiopathic etiology. Glutamate excitotoxicity is one of the proposed hypotheses causing progressive death of motor neurons. We aimed to develop an experimental animal model of this disease to enhance the knowledge of pathophysiological mechanism of ALS. Male Wistar rats were infused with Kainic acid (KA) intra-cisternally for 5 days at the dosage of 50 fmol/day and 150 fmol/day. Locomotor activity, sensory function and histological changes in cervical and lumbar sections of spinal cord were evaluated. Glial Fibrillary Acidic Protein (GFAP) and Neurofilament Protein (NFP) were used as immunohistochemical marker for reactive astrogliosis and neuronal damage respectively. Specific Superoxide Dismutase (SOD) activity of spinal cord was estimated. The locomotor activity in the parameter of observed mean action time remained reduced on 14(th) day after administration of KA. Spinal motor neurons under Nissl stain showed pyknosis of nucleus and vacuolation of neuropil. GFAP expression increased significantly in the lumbar section of the spinal cord with high dose of KA treatment (p<0.05). NFP was expressed in axonal fibres around the neurons in KA-treated rats. A significant increase in specific SOD activity in both cervical and lumbar sections of the spinal cord was found with low dose of KA treatment (p<0.05). This study concludes that spinal cord damage with some features similar to ALS can be produced by low dose intra-cisternal administration of KA.

    Fifty-four per cent of 52 patients presenting to the University of Malaya Medical Centre with a myelopathy for which appropriate investigations uncovered no definite etiology, subsequently developed clinically definite or probable multiple sclerosis. In the subgroup of patients with a presentation indicative of acute/subacute transverse myelopathy, 14 or 52% also went on to develop clinically definite or probable multiple sclerosis, a far higher proportion than previously recorded in the literature. This finding is probably a further manifestation of racial difference in the behaviour of multiple sclerosis. For the group as a whole, the only factor which appeared to be associated with an increased risk of developing multiple sclerosis was female sex; 67% of 33 female patients went on to develop multiple sclerosis after a mean follow-up period of 5.5 years. Other factors such as age of onset, racial composition, level of spinal cord involvement, presence of fever and CSF finding were found not to be important.

    The presence of anatomical anomalies such as absence of C1 posterior arch and presence of C2 high-riding vertebral artery may not allow a conventional C1-C2 fusion, and this patient will require occipitocervical fusion. A 62-year-old lady presented with cervical myelopathy. CT scan demonstrated an os odontoideum with C1-C2 dislocation. The posterior arch of atlas on right C1 vertebra was absent, and there was high-riding vertebral artery on left C2. MRI revealed severe cord compression with cord oedema. The chronic atlantoaxial dislocation was reduced successfully with skeletal traction. Hybrid C1-C2 fusion augmented with autogenous local bone graft with corticocancellous iliac crest bone graft was performed to avoid an unnecessary occipitocervical fusion. She was stable throughout surgery and discharged 6 days later. CT scan 6 months post-operation showed a solid posterior fusion mass. Hybrid C1-C2 fusion can be performed to avoid occipitocervical fusion despite presence of abnormal anatomy at C1 and C2 vertebrae.

    The optimisation of blood pressure management is critical in managing hypotensive episodes in patients with spinal cord injury. Improper handling of this preventable factor will negatively impact the patient recovery prognosis. A 42-year-old man was admitted for a complete spinal cord injury after fell from height. He developed subacute neurological deterioration unrelated to the mechanical instability but due to multiple episodes of hypotension occurring one month after the initial injury. After proper management of blood pressure, his deterioration was halted and no further progression. Spinal cord haemodynamics play an important role in mediating the onset of subacute post-traumatic ascending myelopathy. Better education and awareness on Subacute Post-traumatic Ascending Myelopathy (SPAM) especially to the junior healthcare providers are important to hinder this rare but avoidable condition.

    Glial heterotopia of oropharynx is a congenital anomaly, whereby ectopic mature glial tissue is found around oropharynx isolated from the brain and spinal cord. Herein we report a rare presentation of a mass at the base of tongue in a neonate. In addition, to underscore the rarity of oropharygeal glial heterotopia, we discuss the dilemma in approaching its diagnosis and management in a neonate.

    Functional electrical stimulation (FES) has been used to produce force-related activities on the paralyzed muscle among spinal cord injury (SCI) individuals. Early muscle fatigue is an issue in all FES applications. If not properly monitored, overstimulation can occur, which can lead to muscle damage. A real-time mechanomyography (MMG)-based FES system was implemented on the quadriceps muscles of three individuals with SCI to generate an isometric force on both legs. Three threshold drop levels of MMG-root mean square (MMG-RMS) feature (thr50, thr60, and thr70; representing 50%, 60%, and 70% drop from initial MMG-RMS values, respectively) were used to terminate the stimulation session. The mean stimulation time increased when the MMG-RMS drop threshold increased (thr50: 22.7 s, thr60: 25.7 s, and thr70: 27.3 s), indicating longer sessions when lower performance drop was allowed. Moreover, at thr70, the torque dropped below 50% from the initial value in 14 trials, more than at thr50 and thr60. This is a clear indication of muscle fatigue detection using the MMG-RMS value. The stimulation time at thr70 was significantly longer (p = 0.013) than that at thr50. The results demonstrated that a real-time MMG-based FES monitoring system has the potential to prevent the onset of critical muscle fatigue in individuals with SCI in prolonged FES sessions.

    Sonic hedgehog (SHH) is a vertebrate homologue of the secreted Drosophila protein hedgehog and is expressed by the notochord and floor plate in the developing spinal cord. Sonic hedgehog provides signals relevant for positional information, cell proliferation and possibly cell survival, depending on the time and location of expression. Although the role of SHH in providing positional information in the neural tube has been experimentally proven, the underlying mechanism remains unclear. In this study, in ovo electroporation was employed in the chicken spinal cord during chicken embryo development. Electroporation was conducted at stage 17 (E2.5), after electroporation the embryos were continued incubating to stage 28 (E6) for sampling, tissue fixation with 4% paraformaldehyde and frozen sectioning. Sonic hedgehog and related protein expressions were detected by in situ hybridization and fluorescence immunohistochemistry and the results were analysed after microphotography. Our results indicate that the ectopic expression of SHH leads to ventralization in the spinal cord during chicken embryonic development by inducing abnormalities in the structure of the motor column and motor neuron integration. In addition, ectopic SHH expression inhibits the expression of dorsal transcription factors and commissural axon projections. The correct location of SHH expression is vital to the formation of the motor column. Ectopic expression of SHH in the spinal cord not only affects the positioning of motor neurons, but also induces abnormalities in the structure of the motor column. It leads to ventralization in the spinal cord, resulting in the formation of more ventral neurons forming during neuronal formation.

    Downstream Regulatory Element Antagonist Modulator (DREAM) protein modulates pain by regulating prodynorphin gene transcription. Therefore, we investigate the changes of mRNA and DREAM protein in relation to the mRNA and prodynorphin protein expression on the ipsilateral side of the rat spinal cord after formalin injection (acute pain model). DREAM like immunoreactivity (DLI) was not significantly different between C and F groups. However, we detected the upregulation of mean relative DREAM protein level in the nuclear but not in the cytoplasmic extract in the F group. These effects were consistent with the upregulation of the relative DREAM mRNA level. Prodynorphin like immunoreactivity (PLI) expression increased but the relative prodynorphin mRNA level remained unchanged. In conclusion, we suggest that upregulation of DREAM mRNA and protein expression in the nuclear compartment probably has functional consequences other than just the repression of prodynorphin gene. It is likely that these mechanisms are important in the modulation of pain.

    Congenital dermal sinus (CDS) and occult spinal dysraphism are suspected when a cutaneous marker overlies the spine of a newborn. CDS can have the appearance of a simple dimple and occur within the gluteal cleft without any skin markers. CDS are the commonest cause of intramedullary spinal cord abscess.

    Primary intramedullary germinoma arising in the cervical spinal cord is a very rare entity. We present one such case arising in a young man who presented with radiculopathy and myelopathy, which was partially excised. Upon histological confirmation, he was treated successfully with radiotherapy alone. To our knowledge, this is only the second reported case worldwide which is histologically confirmed. Although extremely rare, differential diagnosis for intramedullary spinal cord tumor should include germinoma.
