In basic research on spinal cord injury (SCI), behavioral evaluation of the SCI animal model is critical. However, it is difficult to accurately evaluate function in the mouse SCI model due to the small size of mice. Although the open-field scoring scale is an outstanding appraisal method, supplementary objective tests are required. Using a compact SCANET system, in which a mouse carries out free movement for 5 min, we developed a novel method to detect locomotor ability. A SCANET system samples the horizontal coordinates of a mouse every 0.1 s, and both the speed and acceleration of its motion are calculated at each moment. It was found that the maximum speed and acceleration of motion over 5 min varied by injury severity. Moreover, these values were significantly correlated with open-field scores. The maximum speed and acceleration of SCI model mice using a SCANET system are objective, easy to obtain, and reproducible for evaluating locomotive function.

Background: Sepsis and multiple organ failure (MOF) remain one of the main causes of death after multiple trauma. Trauma- and infection-associated immune reactions play an important role in the pathomechanism of MOF, but the exact pathways remain unknown. Spinal cord injury (SCI) may lead to an altered immune response, and some studies suggest a prognostic advantage for such patients having sepsis or multiple trauma. Yet these findings need to be evaluated in larger cohorts of trauma patients. Methods: Retrospective, multicenter study, using the data of the TraumaRegister DGU. Patients with and without SCI surviving the initial first 72 hours after trauma were matched according to injury pattern and age. Comparative analysis considered morbidity (sepsis, MOF) and hospital mortality. Results: The study population included 800 matched pairs. As intended by the matching process, patients with cervical SCI had an otherwise comparable injury pattern but a higher severity of trauma (mean Injury Severity Score: 36 vs 29, mean number of diagnosis: 5.6 vs 4.4). They had a higher rate of sepsis (15.9% vs 10.9%, P = .005) and MOF (35.9% vs 24.1%, P < .001) while mortality revealed no significant difference (9.5% vs 9.9%, P = .866). Conclusions: Cervical SCI leads to an increased rate of sepsis and MOF but appears to be favorable with respect to outcome of sepsis and MOF following multiple trauma. Further research should focus on the pathomechanisms and the possible arising therapeutic options.

The evaluation of the abdomen in patients with spinal cord injury (SCI) is challenging for obvious reasons. There are very little data on the incidence and complications of patients who sustain SCI with concomitant intraabdominal injury (IAI). To determine the incidence and outcomes of IAI in blunt trauma patients with SCI, a trauma registry and record review was performed between January 1998 and December 2005. Baseline demographic data, Injury Severity Score, and associated IAI were collected. Two groups were established and outcomes were analyzed based on the presence or absence of IAI. Intraabdominal and hollow viscus injures were found in 15 per cent and 6 per cent, respectively, of 292 patients with blunt SCI. The presence of intraabdominal injury varied according to the level of the SCI: 10 per cent of cervical, 23 per cent of thoracic, and 18 per cent of lumbar SCI. The overall mortality was 16 per cent. The presence of intraabdominal injury was associated with longer intensive care unit length of stay (13 versus 6 days, P < 0.01), hospital length of stay (23 versus 18 days, P < 0.05), higher complication rate (46% versus 33%, P = 0.09), and higher mortality (44% versus 11%, P < 0.01) when compared with patients with SCI without IAI. Intraabdominal injuries are common in blunt SCI. Liberal evaluation with computed tomography is necessary to identify injuries early.

Background: Spinal Cord Injury Without Radiological Abnormality (SCIWORA) is underreported and poorly recognized in adults. This entity is an important subtype of spinal cord injury (SCI) with relatively good outcomes. Despite this, few studies have been performed to determine specific imaging-related prognostic factors. Methods: A retrospective review of adult patients with cervical SCI admitted to two University hospitals from January 2000 to December 2010 was performed. Only patients with an MRI performed within 72 hours after trauma were included. All patients with bony injury or traumatic malalignment were excluded. Data gathered on the remaining patients included demographics, mechanism of injury, severity of SCI, long-term patient outcome, improvement in neurological condition and MRI results. Results: 49 patients selected. Patients with extramedullary hemorrhage showed worse neurological status at initial examination. Disruption of either the anterior longitudinal ligament or ligamentum flavum was associated with worse outcomes at initial examination and at 1-year follow up. Lesion length was also significantly associated with outcomes at 1 year evaluation and initial evaluation. Conclusions: Early MRI has an important prognostic value in patients suffering SCIWORA. Lesion length is a powerful predictor of outcome. Soft tissue injury and spinal cord changes play a role in the severity of injury as well as the ability to recover.

Although, biomarkers are regarded as an important tool for monitoring injury severity and treatment efficacy, and for predicting clinical evolution in many neurological diseases and disorders including spinal cord injury, there is still a lack of reliable biomarkers for the assessment of clinical course and patient outcome. In this study, a biological dataset of 60 cytokines/chemokines, growth factorsm and intracellular and extracellular matrix proteins, analyzed in CSF within 24 h of injury, was used for correlation analysis with the clinical dataset of the same patients. A heat map was generated of positive and negative correlations between biomarkers and clinical rating scale scores at discharge, and between biomarkers and changes in clinical scores during the observation period. Using very stringent statistical criteria, we found 10 molecules which correlated with clinical scores at discharge, and five molecules, which correlated with changes in clinical scores. The proposed methodology may be useful for generating hypotheses regarding “predictive” and “treatment effectiveness” biomarkers, thereby suggesting potential candidates for disease-modifying therapies using a “bed-to-bench” approach.
