Intramedullary spinal cord and filum tumours-long-term outcome: single institution case series.

BACKGROUND: Intramedullary spinal cord tumours are rare and account for about 2-4% of primary CNS tumours. Ependymomas and astrocytomas are most frequent. The aim of this study was to evaluate the long-term neurological outcome, quality of life (QoL), survival, need for additional treatment and frequency of neuropathic pain in a patient group treated at a tertiary university hospital. METHOD: Retrospective descriptive study of 52 long-term survivors with intramedullary or filum tumours consenting to participate in this study. Fifty-six operations were performed in 48 patients. Clinical and radiological follow-up period was 113 and 117 months, respectively. RESULTS: Good neurological outcome (ASIA score D or E, modified McCormick grade 1 or 2) was achieved in 88%. We found two negative prognostic factors in regards of severe disability which were large craniocaudal tumour size (p = 0.004) and histologic verified astrocytomas (p = 0.002). SF-36 results showed significantly lower results on all five subdomains concerning physical function, whereas scores for mental health and role emotional showed no significant differences compared to Norwegian norms. Ten patients including all astrocytoma patients, one primitive neuroectodermal tumour and three recurrent tumours of filum terminale had adjuvant therapy. None of the patients with intramedullary ependymoma had adjuvant therapy. Neuropathic pain was present in 54% of patients at the last follow-up. CONCLUSION: This series shows that good results can be obtained with surgery for intramedullary tumours, even without perioperative neurophysiological monitoring. Multicentre studies are needed for further evaluation of negative and positive prognostic factors to further improve outcome.

Non-traumatic spinal cord injury in Norway 2012-2016: analysis from a national registry and comparison with traumatic spinal cord injury.

STUDY DESIGN: Registry-based cross-sectional study. OBJECTIVES: To describe and analyze epidemiological and demographic characteristics of non-traumatic spinal cord injury (NTSCI) and to compare persons with NTSCI and traumatic spinal cord injury (TSCI). SETTING: A total of 225 non-traumatic and 349 traumatic SCI patients were admitted for primary rehabilitation at one of the three specialized SCI departments in Norway (located in Bergen, Trondheim, and Oslo) from 2012 to 2016. Patients who consented to registration in the Norwegian Spinal Cord Injury Registry (NorSCIR) were included. METHODS: Data were collected using the International SCI Core Data Set, as recommended by the International Spinal Cord Society (ISCoS). Demographics and injury characteristics were analyzed descriptively. The NTSCI and TSCI groups were compared using a Mann-Whitney U test and chi-square test. RESULTS: The mean age of the NTSCI patients was 55 years, and 59% were male. The incidence of NTSCI was 7.7-10.4 per million person-years, which is lower than the incidence of TSCI. NTSCI individuals were older, less severely injured, and their length of stay at the hospital was shorter than the TSCI individuals. The results may be influenced by the inclusion criterion in the registry. This makes the analyzed sample for NTSCI less complete. However, the majority of patients with nonprogressive NTSCI are included in the NorSCIR. CONCLUSION: For the first time, we are able to provide the national epidemiological status on NTSCI based on available data from the national registry. Further studies are required to improve the capture of NTSCI for future incidence studies.

Epidemiology of traumatic spinal cord injury in Norway in 2012-2016: a registry-based cross-sectional study.

STUDY DESIGN: A registry-based cross-sectional study. OBJECTIVES: To analyse the epidemiological and demographic characteristics of persons with traumatic spinal cord injury (TSCI) in Norway. SETTING: TSCI patients admitted for primary rehabilitation to one of the three specialised spinal cord injury (SCI) departments (located in Bergen, Trondheim, and Oslo) and consented to the Norwegian Spinal Cord Injury Registry (NorSCIR). METHODS: Analysis of data from NorSCIR during a 5-year period (2012-2016) was performed. Data were collected by using the International SCI Core Data Set as recommended by the International Spinal Cord Society (ISCoS). RESULTS: The lowest incidence of TSCI was 11.4/million (2012), and the highest incidence was 15.9/million (2014). In the study period, 349 individuals were registered with TSCI. In total, 76% were male, and the mean age was 47 (SD ± 19) years. We observed dominance in the 60-74 years age group. The distribution between tetraplegia and paraplegia was 48%/42%. For those initially classified as American Spinal Cord Injury Association Impairment Scale (AIS) grade A (complete injury), 77% remained grade A at discharge. Considerable changes during primary rehabilitation after incomplete lesions were observed. Most patients (68%) were discharged home after primary rehabilitation. Falls were the main cause of TSCI (47%) and occurred more often during the weekend. CONCLUSION: Through a National Medical Quality Registry based on internationally provided data sets, we are able to present systematic and updated data from Norway.

Telehealth for people with spinal cord injury: a narrative review.

STUDY DESIGN: Narrative review. OBJECTIVES: To find and discuss what has been published about the use of telehealth, on people with spinal cord injury (teleSCI). SETTING: International. METHOD: Cochrane Library, Ovid Medline, EMBASE and CINAHL, from 1996 till June 2017 have been searched. Searches in  PsycINFO, from 1996 till September 2017, were included afterwards. Extracted data include studies in English language, containing information about spinal cord injury and disorders, and telehealth. Literature reviews, systematic reviews, and studies containing other types of neurological disorders, were excluded. Studies were grouped based on how and to whom telehealth was offered. RESULTS: Twenty nine studies were included in the review. They were categorized according to the way teleSCI was provided, and to what modality was used. Some studies utilized more than one modality. TeleSCI seems to be favorable concerning treatment and follow-up, as well as favorable socioeconomically and environmentally. The studies spanned across several aims and outcomes. There was also heterogeneity in number of participants, the differences in modalities, and in the level of evidence. Thus  it was challenging to compare studies  and make future recommendations. CONCLUSIONS: TeleSCI can be used for examination and guiding purposes. Further research is warranted to evaluate optimal utilization, methodology and efficacy. SPONSORSHIP: The first author has received funding from the Norwegian Extra Foundation.

Long-term outcome after spinal cord infarctions.

OBJECTIVES: To investigate long-term outcome in patients with spontaneous spinal cord infarctions and secondly to compare outcome with that of patients with cerebral infarction. MATERIAL AND METHODS: The study includes 30 patients with spinal cord infarction discharged between 1995 and 2010. Surviving patients were contacted by telephone and sent a questionnaire. Data on employment, function, depression, fatigue, pain, and quality of life were obtained and compared to similar data obtained from a group of patients with cerebral infarction. RESULTS: Seven patients with spinal cord infarction had died after a mean follow-up of 7.1 years. Mortality was associated with poor functioning in the acute phase. Thirteen of 20 responding patients were able to walk. Compared to patients with cerebral infarction, patients with spinal cord infarction had significantly lower mortality, poorer functioning, higher re-employment rate, and more pain. CONCLUSION: Many patients with spinal cord infarction experience significant improvement. Even though functional outcome is worse, the mortality rate is lower and the frequency of re-employment higher among patients with spinal cord infarction compared to patients with cerebral infarction.

Impact of fatal cases on the epidemiology of traumatic spinal cord injury in Estonia.

BACKGROUND AND PURPOSE: Most epidemiological studies on traumatic spinal cord injury (TSCI) have not included patients who die before hospitalization. The aim of the research was to study the incidence of TSCI by including the individuals who die at the scene of the accident in addition to data retrieved from all hospitals in Estonia. METHODS: Medical records of patients with TSCI from all hospitals in Estonia from 2005 to 2007 were studied. With collaboration from the Estonian Forensic Science Institute the data of the victims of TSCI who died before hospitalization were included. RESULTS: From 2005 to 2007, 391 TSCI cases were identified: 183 patients were found retrospectively from medical records and 208 cases were detected from autopsy reports. Fifty-three per cent of patients died before hospitalization. The annual incidence rate was 97.0 per million population (95% confidence interval 87.4-106.6). The mean age at injury was 44.4 ± 18.7 years. Motor vehicle accidents were the leading cause of TSCI amongst the individuals who died before hospitalization (75%). Falls accounted for the highest number of TSCIs (43%) amongst the patients who reached hospital. CONCLUSIONS: Our study shows that, when the cases that die at the scene of the accident are included, the incidence of TSCI in Estonia rises from 39.7 to 97.0 per million population.

Factors influencing optimal seating pressure after spinal cord injury.

STUDY DESIGN: Retrospective, cross-sectional design. OBJECTIVES: To identify factors that predict unsatisfactory seating pressure in spinal cord-injured (SCI) individuals. SETTING: Seating Clinic at the University Hospital, Norway. METHODS: All wheelchair users with traumatic SCI hospitalized between 1 January 2007 and 31 December 2010 were included. Individual assessment by a team was performed. To measure seating pressure, a computerized seating pad with sensing points 40 × 40 cm was used. Primary end points were defined as satisfactory or unsatisfactory seating position based on measured pressure (more or less 100 mm Hg), clinical findings and physical activity level. To explore possible risk factors for high seating pressure, both univariate and multivariate regression analysis were performed. RESULTS: A total of 75 persons with SCI were assessed, 39 (52%) with unsatisfactory result. Statistical analysis revealed that use of manual wheelchair (odds ratio (OR)=6.86, confidence interval (CI) 1.77-26.63) and history of pressure ulcer (OR=8.47, CI 2.46-29.13) significantly increase the risk of unsatisfactory seating pressure. Paraplegia caused significantly higher risk (OR=2.5, CI 0.99-6.34) in the univariate model, probably because the SCI with tetraplegia do prefer electrically powered wheelchairs. CONCLUSIONS: Use of manually driven wheelchairs and persons with previous pressure ulcer are at significant risk of high seating pressure and consequently developing new pressure ulcers. The patients from these subcategories need close follow-up regarding seating position and prevention of pressure ulcers.

Traumatic spinal cord injury in two European countries: why the differences?

BACKGROUND AND PURPOSE: The aim of the study was to compare the incidence, causes, severity and mortality of traumatic spinal cord injury (TSCI) in Western Norway and Estonia from 1997 to 2001. METHODS: The patients were identified from hospital records. All patients were followed until death or 14 October 2011. Analysed data included demographic data, causes of injury, neurological level, American Spinal Injury Association Impairment Scale and mortality. RESULTS: A total of 71 patients in Western Norway and 244 in Estonia were included. The standardized incidence rate per million was 24.9 (CI 95%, 19.4-31.7) for Western Norway and 37.4 (CI 95%, 32.8-42.5) for Estonia. Falls was the most frequent cause of TSCI in both countries. The incidence of TSCI was highest among men in their 20s in Estonia and men in their 70s in Western Norway. The median survival time among the deceased was 4.0 (95% CI, 1.50-6.50) years in Norway and 2.8 (95% CI, 1.54-4.04) in Estonia. The mean standardized mortality ratio (SMR) was 5.00 (95% CI, 4.00-6.20) in Estonia and 1.89 (95% CI, 1.23-2.77) in Western Norway. CONCLUSION: Although the two cohorts had similar demographic, injury and clinical characteristics, the age profile of the victims was different. The incidence rate was 1.5 times higher and SMR was 2.7 times higher in Estonia. Probable explanations for the different outcomes of the two European countries are socioeconomic differences, lower physical activity level, lower life expectancy and insufficient injury prevention programmes in Estonia.

High incidence of traumatic spinal cord injury in Estonia.

STUDY DESIGN: Retrospective population-based cohort study. OBJECTIVES: To provide national data on epidemiology of traumatic spinal cord injury (TSCI) among the population of Estonia from 1997 to 2007. SETTING: All Estonian hospitals. METHODS: Medical records of patients with TSCI from all regional, central, general and rehabilitation hospitals in Estonia were retrospectively reviewed. Epidemiological characteristics, etiology, neurological level and severity of injury, concomitant injuries were analyzed. RESULTS: A total of 595 patients with TSCI from 1 January 1997 to 31 December 2007 were identified. The male to female ratio was 5.5:1. The mean age at injury was 39.0 years. The crude incidence rate was 39.7 (95% confidence interval: 36.6-43.0) per million population. The most frequent cause of TSCI was falls (41%), followed by traffic accidents (29%). Alcohol consumption preceded 43% of injuries. The lesion level was cervical in 59.4%, thoracic in 18.3% and lumbar/sacral in 22.3%. CONCLUSION: Compared to recent studies from Europe, where the incidence of TSCI is between 15 and 30 per million population, the incidence of TSCI in Estonia is among the highest. The rates are significantly higher in men compared with women and especially among the youngest men. The leading cause of TSCI is falls. A significant proportion of injuries are related to alcohol consumption before trauma in Estonia.
