Spontaneous Epidural Hematoma during Pregnancy

Spontaneous epidural hematoma during pregnancy is rare but it requires urgent diagnosis and decompressive surgery because the prognosis is mainly linked to the speed of treatment. Reporting the case of a pregnant woman in the 8th month of pregnancy who presented back pain with paraplegia, an MRI was performed on her returning in favor of a compressive hematoma at the D1D2 level. Followed by a D1D2 laminectomy with evacuation of the hematoma. The postoperative period is marked by total neurological recovery.

Complete Neurological Recovery In A 3 Year Old Presenting With Posterior Reversible Encephalopathy Syndrome Due To Idiopathic Hypertension – A Case Report

Posterior reversible encephalopathy syndrome is an acute neurological illness presenting with clinical symptoms and distinctive MRI findings. Symptoms include headaches, seizures, altered consciousness as well as visual impairment. PRES is always accompanied by peculiar radiological findings of edematous change affecting the rear cerebral area. It commonly occurs in settings where patients are undergoing hypertensive crisis, or there is the use of steroids, calcineurin inhibitors, in the nephritic state or end-stage renal disease. The management includes treating the underlying cause and symptomatic therapy. However, due to relatively fewer pediatric reports, its management isn’t specific and rather based on experience. Our patient is a 3-year-old male, who presented with hypertensive crisis and MRI findings confirmed it to be a case of PRES. He was managed with a combined regime of antihypertensive and steroids which lead to complete neurological recovery and resolution of PRES. There are a scarce number of case reports on the use of steroids for the treatment of vasogenic oedema in children.

Can the rate of mortality and neurological recovery be predicted from the time of onset of symptoms and MRI grade in patients with cerebral fat embolism?

Aims The aim of this study was to assess whether it is possible to predict the mortality, and the extent and time of neurological recovery from the time of the onset of symptoms and MRI grade, in patients with the cerebral fat embolism syndrome (CFES). This has not previously been investigated. Methods The study included 34 patients who were diagnosed with CFES following trauma between 2012 and 2018. The clinical diagnosis was confirmed and the severity graded by MRI. We investigated the rate of mortality, the time and extent of neurological recovery, the time between the injury and the onset of symptoms, the clinical severity of the condition, and the MRI grade. All patients were male with a mean age of 29.7 years (18 to 70). The mean follow-up was 4.15 years (2 to 8), with neurological recovery being assessed by the Glasgow Outcome Scale and the Mini-Mental State Examination. Results In all, seven who had early-onset CFES (< 24 hours), and a severe Takahashi grade on MRI, died. There was a significant association between the time of onset of neurological signs and mortality (p = 0.035). Mortality was also significantly associated with a severe Takahashi grade (p < 0.001). Among the 27 surviving patients, 26 (96.3%) recovered completely. One (3.7%) had a cognitive deficit. The mean time to recovery was 4.7 weeks (2 to 13), with late recovery aftereight eight weeks being recorded in three patients. Conclusion There was a significantly increased rate of mortality in patients with CFES who had an early onset of symptoms and a severe grade on MRI. Complete neurological recovery can be expected in most patients with CFES who survive. Cite this article: Bone Joint J 2022;104-B(1):142–149.

Pursuing More Aggressive Timelines in the Surgical Treatment of Traumatic Spinal Cord Injury (TSCI): A Retrospective Cohort Study with Subgroup Analysis

Background: The optimal timing of surgical therapy for traumatic spinal cord injury (TSCI) remains unclear. The purpose of this study is to evaluate the impact of “ultra-early” (<4 h) versus “early” (4–24 h) time from injury to surgery in terms of the likelihood of neurologic recovery. Methods: The effect of surgery on neurological recovery was investigated by comparing the assessed initial and final values of the American Spinal Injury Association (ASIA) Impairment Scale (AIS). A post hoc analysis was performed to gain insight into different subgroup regeneration behaviors concerning neurological injury levels. Results: Datasets from 69 cases with traumatic spinal cord injury were analyzed. Overall, 19/46 (41.3%) patients of the “ultra-early” cohort saw neurological recovery compared to 5/23 (21.7%) patients from the “early” cohort (p = 0.112). The subgroup analysis revealed differences based on the neurological level of injury (NLI) of a patient. An optimal cutpoint for patients with a cervical lesion was estimated at 234 min. Regarding the prediction of neurological improvement, sensitivity was 90.9% with a specificity of 68.4%, resulting in an AUC (area under the curve) of 84.2%. In thoracically and lumbar injured cases, the estimate was lower, ranging from 284 (thoracic) to 245 min (lumbar) with an AUC of 51.6% and 54.3%. Conclusions: Treatment within 24 h after TSCI is associated with neurological recovery. Our hypothesis that intervention within 4 h is related to an improvement in the neurological outcome was not confirmed in our collective. In a clinical context, this suggests that after TSCI there is a time frame to get the right patient to the right hospital according to advanced trauma life support (ATLS) guidelines.

Preoperative Magnetic Resonance Imaging Signal Intensity Classification Is Associated With Clinical Presentation and Surgical Outcomes in Myelopathy Caused by Thoracic Ossification of Ligamentum Flavum: A Multicenter Study

Study Design Retrospective Cohort Study Objectives To explore whether classification of the increased signal intensity (ISI) on magnetic resonance imaging (MRI) correlates with clinical presentations and outcomes in symptomatic thoracic ossification of ligamentum flavum (T-OLF) patients. Methods All patients with symptomatic T-OLF who underwent laminectomy at four institutions were reviewed. The ISI on preoperative T2-weighted MRI was divided into 3 groups, Grade 0, none; Grade 1, light (obscure); and Grade 2, intense (bright). Neurological function before surgery and at follow-up was evaluated by the revised Japanese Orthopedic Association (JOA) score. Patients’ demographics, clinical manifestations, and surgical outcomes were compared. Results A total of 94 patients were involved. Preoperative MRI showed 32 patients in Grade 0, 39 patients in Grade 1, and 23 patients in Grade 2. Low extremities numbness, weakness, and clinical signs were less frequent in Grade 0 patients. The grade of ISI was correlated with the duration of symptoms and cord compression. Grade 0 patients had a better preoperative JOA score than those with ISI changes, while Grade 2 patients showed worse neurological recovery, longer duration of operation, more intraoperative blood loss, and a higher incidence of perioperative complications. Conclusion The classification of ISI is an effective parameter for preoperatively assessing cord compression, clinical severity, and surgical outcomes in T-OLF patients. Grade 0 patients have relatively mild neurological impairment but are more likely to be misdiagnosed. Grade 2 indicates the worst clinical impairment and neurological recovery, and implies a risky and challenging surgery.

Mielopathy related to copper deficiency after bariatric surgery: case report / Mielopatia relacionada à deficiência de cobre após cirurgia bariátrica: relato de caso

Copper is an essential enzymatic cofactor in many stages of normal functioning of human body, acting mainly in hematological, vascular and neurological functions. Its deficiency is linked to some conditions as highly isolated oral zinc intake, parenteral nutrition and after bariatric surgery. Neurological symptoms due copper deficiency include gait abnormalities, sensitive ataxia and sensitive neuropathic symptoms. We present a case of copper deficiency myelopathy after bariatric surgery. Copper deficiency myelopathy is poorly diagnosed, being imperative the early recognition of the condition aiming better outcomes and neurological recovery.

726 Outcomes of ischaemic stroke in patients with atrial fibrillation

Aims Atrial fibrillation (AF) increases the risk of ischaemic strokes (IS) and is associated with a more severe neurological impairment. We sought to investigate whether AF also impacts the neurological recovery and whether patients with AF have a different response to the treatment. Methods and results Data of patients admitted to the Stroke Unit of our institution from January to December 2020 were retrieved from the local database. The stroke severity was calculated by mean of the National Institute of Health Stroke Scale (NIHSS) at hospital admission (NIHSSad), at 24 h (NIHSS24) and at discharge (NIHSSdis). The functional capacity was assessed by the modified Rankin score (mRS). As for the neurological recovery, this was assessed by the delta NIHSS at 24 h (Δ24 = NIHSS24−NIHSSad) and at discharge (Δdis = NIHSSdis−NIHSSad). Out of 545 patients with IS 64 had known history of AF or were admitted with AF. Patients with AF had higher NIHSSad (13.9 ± 7 vs. 8.5 ± 7; P &lt; 0.001) and NIHSS24 (9.6 ± 8 vs. 6.4 ± 7; P = 0.007) than patients without, however the neurological improvement was greater (Δdis −7.4 ± 9 vs. −3.4 ± 6; P = 0.002), indeed the NIHSSdis was similar (4.2 ± 5 vs. 4.2 ± 6; P = 0.98). Patients with AF also had a more impaired mRS before the ischaemic event and at discharge (2.4 ± 1.9 vs. 1.6 ± 1.7, P = 0.02; 1.2 ± 1.2 vs. 0.4 ± 0.9, P &lt; 0.001). Among AF patients with CHADVASC ≥ 3, 34% of them were taking antiplatelet therapy, 31% anticoagulants, and 35% didn’t take any therapy. Of interest, no differences in the NIHSSad nor in the NIHSSdis were found between them and neither in the Δdis. As for the treatment of AF patients, no differences in the neurological recovery were observed between those treated with intravenous thrombolysis and those not treated at all (Δdis 2.8 ± 5 vs. 2.8 ± 8, P = 1), whereas the Δdis was significantly higher in patients treated with mechanical thrombectomy (−11.7 ± 7, P = 0.007). Conclusions Patients with AF experience more severe stroke, however the neurological recovery is greater than in patients without the arrhythmia. The treatment with antiplatelets or anticoagulants before the event does not reduce the severity of the stroke and does not influence the improvement of the NIHSS at discharge. The mechanical thrombectomy is more effective in reducing the neurological impairment.
