Spinal Cord Series and Cases最新文献

Introduction: Spinal cord infarction is a rare but often devastating disorder. The pathogenesis of most non-surgical cases involves atherothrombosis and treatment with anticoagulation and antiplatelet agents may be indicated. Functional recovery in most cases is poor. We describe five cases of spinal cord infarction and provide details on their functional outcomes after long-term (>10 years) follow-up.

Case presentation: A 28-year-old female presented at 16 weeks gestation with chest and back pain and paraesthesia in her fingers. Magnetic resonance imaging on admission revealed a spinal cord lesion extending from C5-T8. She was treated with anticoagulation and rehabilitation. Six years following presentation she was able to return to work. A 42-year-old male experiencing central chest pain and leg weakness was initially diagnosed as having acute coronary syndrome. Following discharge, he was re-admitted with urinary retention and leg weakness. Magnetic resonance imaging revealed a spinal cord lesion extending from T4 to T7. He was treated with anticoagulation, and eight months following presentation he regained full muscle strength but required intermittent self-catherisation. Three further cases are described.

Discussion: The aetiology of non-surgical spinal cord infarction is not always evident, but is commonly associated with atherothrombosis. There are often delays in making a diagnosis, but early recognition and prompt treatment of spinal cord infarction is essential. Long-term functional outcomes are often poor and typically reflect the severity of initial presentation. This case series is unique as it has one of the longest follow-up periods described in the literature.

Study design: A systematic review and meta-analysis OBJECTIVE: To determine the global frequency of osteomyelitis in individuals with spinal cord injury who have pressure injuries (SCI-PI).

Methods: A comprehensive search on PubMed, EMBASE, Scopus, and the Web of Science has been conducted until November 2023. The Cochrane Handbook for Systematic Reviews was followed. Cohort and cross-sectional studies included SCI-PI participants who reported the frequency of osteomyelitis without language restriction. Data extraction was performed by four reviewers in two groups. We used the Newcastle-Ottawa Quality Assessment Scale for quality assessment. The Chi-squared and I² tests were applied to detect heterogeneity between studies. Also, a random-effects model was performed for the report data.

Results: Ten out of 986 studies met our eligibility criteria, with 492 SCI-PI individuals. It was discovered that most SCIs were thoracolumbar injuries and male. There was a history of PI in more than half the patients. SCI was primarily caused by trauma. A meta-analysis revealed a significantly heterogeneous 43.0% osteomyelitis frequency. There was no evidence of publication bias. Subgroup analysis based on study quality revealed that the frequency of osteomyelitis in low-quality studies was 34.5%, whereas the frequency in high-quality research was 47.4%. Furthermore, the overall frequency of osteomyelitis was 29.0% in the subgroup analysis of research carried out in the USA.

Conclusions: Our study highlights the significant burden of osteomyelitis among SCI-PI individuals. These findings underscore the pressing need for standardized diagnostic and management protocols to mitigate the morbidity associated with osteomyelitis in this vulnerable population.

Study design: Retrospective case series of 48 patients.

Objectives: This study's primary objective was to provide a clinical description of a group of individuals with a working diagnosis of idiopathic spinal cord herniation (ISCH). The secondary objectives were to appreciate the natural history of these patients and describe their clinical evolution with conservative or surgical management.

Setting: The study was carried out at l'Hôpital de l'Enfant-Jésus, CHU de Québec (Québec, Canada), a tertiary care university hospital.

Methods: This case series study is based on routinely collected data. Forty-eight (48) cases were identified as having an ISCH on MR imaging, between 2009 and 2019. Their medical files have been searched retrospectively. Patient characteristics were described according to their asymptomatic or symptomatic status.

Results: The mean age of patients at the time of diagnosis was 52.5 years. Most of the patients identified were asymptomatic (69%) and followed clinically. The main neurologic presentation for the symptomatic group was Brown-Séquard-like syndrome. 20% of the symptomatic patients were rapidly treated surgically after consultation with the neurosurgeon. The mean follow-up duration was 56 months for asymptomatic patients and 51 months for symptomatic patients. Most of our patients (41 out of 45) were considered stable or unchanged at follow-up. There was no neurological progression in all asymptomatic patients.

Conclusions: Our study shows that ISCH and its variants are not always symptomatic and may be a fortuitous finding. As the natural history may be non-progressive, it is probably appropriate to treat some cases expectantly.

Study design: Longitudinal observational study. Measurements were undertaken between weeks 4-6 post-spinal cord injury (SCI), repeated at week 8 and every 4 weeks thereafter until week 20 or rehabilitation discharge, whichever occurred first.

Objectives: Observe variation in measured resting energy expenditure (REE) and body composition in males undergoing SCI rehabilitation, compare REE with SCI-specific prediction equations incorporating fat-free mass (FFM), and explore the prevalence of clinical factors that may influence individual REE.

Setting: Spinal Injuries Unit, Brisbane, Queensland, Australia.

Methods: Indirect calorimetry was used to measure REE and bioimpedance spectroscopy to assess body composition. Four SCI-specific FFM-based REE and basal metabolic rate (BMR) prediction equations were compared to measured REE. A clinically significant change in REE was defined as +/- 10% difference from the week 4-6 measurement. Clinical factors that may affect REE variations were collected including infection, pressure injuries, autonomic dysreflexia, spasticity, and medications.

Results: Fifteen people participated (mean age 35 ± 13 years, 67% paraplegic). There was no statistically significant change in mean REE, weight, or body composition, and the Chun and Nightingale BMR prediction equations performed best (r_c > 0.8 at all time points). One-third of participants had >10% change in REE on 11 occasions, with clinical factors not consistently associated with the observed changes.

Conclusion: During SCI rehabilitation, mean REE, weight, and body composition remain unchanged, and FFM-based BMR prediction equations may be an acceptable alternative to indirect calorimetry. Future research designs should avoid single indirect calorimetry measures as snapshot data may not represent typical REE in this population.

Study design: Retrospective population based study on traumatic spinal cord injury (SCI) in Ireland.

Objectives: To gather the most recent epidemiological data prior to the implementation of a new national trauma strategy. Also, to consider if the COVID-19 pandemic impacted on SCI epidemiology in Ireland.

Setting: Republic of Ireland.

Methods: All patients with TSCI discharged from the National Rehabilitation Hospital (NRH), the national acute SCI unit and two neurosciences centres were included. The International Spinal Cord Injury Core Data Set was collected on all patients at discharge from rehabilitation between 2017 and 2022.

Results: Overall crude incidence of TSCI was 14 per million per year, ranging between 11.3 and 18.4. 12.7% of patients did not survive to discharge from hospital. In those completing rehabilitation, the mean age of injury onset was 50.1 years (SD 19.9). Males accounted for 75.7%. The most common impairment was incomplete tetraplegia, 45.3% of all TSCI. Leading aetiology was falls, 53.9% of injuries. Patients with incomplete tetraplegia and those whose cause of injury were falls were older than those with all other impairments and injury aetiologies (p < 0.001).

Conclusions: Overall incidence of TSCI is similar to our previous studies. Also similar is the predominant pattern of older people sustaining falls resulting in incomplete tetraplegia.

Introduction: Cauda equina syndrome (CES) related to beta thalassemia with extramedullary hematopoiesis is a rarely reported and challenging clinical presentation. A thorough literature review revealed only a limited number of documented cases, each demonstrating a variety of treatment modalities with divergent outcomes.

Case presentation: In this case, a 29-year-old male with beta thalassemia, undergoing frequent blood transfusions, and with a history of splenectomy, presented with 2 days of worsening in his lower back pain, extending to both lower limbs, numbness, and urinary incontinence. Following the ASIA ISNCSCI scoring system for physical assessment, there was a significant decrease in anal tone and perianal sensation, suggesting possible sacral nerve roots involvement, but no other upper or lower extremities sensory or motor deficits were detected. Provided with the patient history of frequent blood transfusion and Thalassemia for which hematology referral was promoted. Spinal MRI revealed extramedullary hematopoiesis, disc protrusion, and cauda equina compression.

Discussion: Spine surgery, including decompression and laminectomy, resulted in improved back pain and lower limb symptoms during the one-year follow-up. However, persistent sensory impairment and neurogenic bladder necessitated ongoing urological management. The absence of clear guidelines for the management of such cases underscores the need for further data collection and comprehensive outcome reviews.

Introduction

Patients with spinal cord injury/disorder (SCI/D) and neurogenic lower urinary tract dysfunction (NLUTD) are on a 16–28 folder higher risk for bladder cancer [1]. Whereas in the general population 90% of bladder tumors are transitional cell carcinoma (TCC) patients with NLUTD have a shift to squamous cell carcinoma with 36,8% and only 46.3% TCC [2]. In addition, there is a significant increase in the bladder cancer-specific death rate in SCI patients (3rd most common) compared to the general population (10th most common) [2]. Chronic inflammation and mechanical irritation by permanent indwelling catheters are discussed as risk factors for developing bladder cancer. Typical symptoms of bladder cancer are often absent in patients with NLUTD and a reliable screening has not been established.

Case presentation

We present a case series of six patients with SCI and with squamous cell carcinoma diagnosed in the last 5 years in our institution. In five patients, bladder management was performed by indwelling suprapubic catheters, one patient used reflex voiding. Three patients were diagnosed during the regular, annual neuro-urological check-up, the remaining due to increasing spasticity and autonomic dysregulation. Subsequently, five patients underwent cystectomy with ileal conduit or uretercutaneostomy, one patient refused further surgical treatment. Four patients died within one year after diagnosis.

Discussion

Squamous cell carcinoma of the bladder is more common in patients with NLUTD. Chronic inflammation and mechanical irritation may be the reasons for carcinoma genesis. A regular check including cystoscopy is strongly recommended to detect tumor development early.

Introduction: Autonomic dysreflexia (AD) is a potentially life-threatening syndrome that can occur in patients with traumatic injury to the spinal cord; however, it has not been well described in patients with non-traumatic spinal cord injury (SCI) from cancer and its treatments.

Case presentation: We report four cases of autonomic dysreflexia secondary to primary spinal cord tumors and metastatic disease to the spine, and as sequela to cancer treatment. The clinical characteristics, diagnostic considerations, and therapeutic strategies used to mitigate the symptoms are discussed.

Discussion: The case series shows that AD is a rare but important condition to consider among patients with cancer-related SCI. There is a need for close monitoring and early identification of this syndrome in this population. Therapeutic strategies are available to mitigate these symptoms and risks of complications.

Introduction: Ligamentum flavum haematoma (LFH) is an extremely rare entity, found mostly in the lumbar and thoracic ligamentum flavum and seldom in the cervical ligamentum flavum. Cervical LFH can cause paralysis in patients. We describe a case of LFH in the cervical spine that accepted surgical treatment.

Case presentation: A 70-year-old man with incomplete spinal cord injury presented with sudden paralysis of his left limbs for 10 days and hemi-hypaesthesia below the level of the right clavicle. Magnetic resonance imaging (MRI) showed a space-occupying lesion in the left ligamentum flavum between the C4 and C5 laminae. The preliminary diagnoses were concluded to be incomplete spinal cord injury, spinal epidural lesions, and cervical spinal stenosis. After a posterior C3-C6 laminectomy with lateral mass screw instrumentation, the muscle strength and sensation recovered partially. The lesion was greyish black and located in the ligamentum flavum. A pathological examination identified it as a haematoma of the ligamentum flavum. The patient was discharged 15 days after the operation and commenced rehabilitation.

Discussion: The LFH was mainly caused by slight trauma during gentle activities and contributed by many factors. MRI is an essential tool but pathological diagnosis is the gold standard. Most LFH patients can be treated surgically.

Introduction: Osteochondromas, also known as osteocartilaginous exostosis, are among the most common benign cartilaginous bone tumors, primarily occurring as solitary lesions. While typically found in long bones, spinal involvement is rare, accounting for only a small percentage of benign lesions in this location. Solitary osteochondromas responsible for spinal cord compression are seldom.

Case presentation: We describe the case of a 34-year-old male with no significant medical history, presenting with progressive symptoms suggestive of spinal cord compression. Imaging studies revealed a bony lesion originating from the left lateral aspect of the posterior arch of the T8 vertebra, causing spinal cord compression and myelopathy. Surgical intervention was necessary to decompress the spinal cord and obtain histological samples, resulting in immediate postoperative improvement in motor function. Pathologic exam concluded to an osteochondroma.

Discussion: Osteochondromas primarily affect growing bones and are more commonly observed as solitary lesions, particularly in male patients. Spinal involvement is rare, and neurological symptoms are typically indicative of intracanalar extension of the exostosis, leading to compression of neural elements. Imaging modalities such as MRI are crucial for assessing cartilage thickness and the impact of compression on the spinal cord.
