Clinical and radiological characteristics of spinal epidural lipomatosis: A retrospective review of 90 consecutive patients

BackgroundThe epidemiology and clinical characteristics of spinal epidural lipomatosis (SEL) have been well-reported in the literature. However, few studies investigated the concomitant spinal pathologies that were present in patients with SEL. Therefore, we aimed to summarize the clinical and radiological characteristics of patients with SEL diagnosed on spinal imaging.MethodsPatients who were diagnosed with SEL on magnetic resonance imaging from January 2018 to October 2020 at our institution were included in the study. Clinical data was collected using a standardized data collection form. SEL was graded using a modified version of the Borré grading system. Factors associated with moderate or severe SEL were determined using multiple logistic regression.ResultsA total of 90 patients were included in the analysis. The mean (±SD) age was 59.3 (±17.1) years, and 62 patients (68.9%) were male. 61 patients (67.8%) had moderate or severe SEL. Most patients were overweight or obese (57 patients, 63.3%). The most common presenting symptoms was back pain (57 patients, 63.3%). SEL was diagnosed incidentally in 42 patients (46.7%). The lumbar spine was the most common site of SEL (35 patients, 38.9%). The most common concomitant spinal pathologies were disc bulge (83 patients, 92.2%) and flavum hypertrophy (60 patients, 66.7%). Moderate or severe SEL was associated with WHO Obesity Class, back pain or radicular leg pain at first presentation, and SEL that was worst at the lumbar or lumbosacral spinal level.ConclusionsModerate or severe SEL were independently associated with WHO Obesity Class, back pain, radicular leg pain, and SEL that was worst at the lumbar or lumbosacral spinal level. Future studies should prospectively evaluate whether weight loss therapy is warranted in patients with SEL.

目的分析长臂单轴椎弓根螺钉经 Wiltse入路在单纯性胸腰椎压缩性骨折中的应用效果及对肌肉损伤的影响。方法选取自 2018年 1月至 2020年 8月周口市中心医院收治的单纯性胸腰椎压缩性骨折病人 87例，根据复位固定术式不同，分为观察组 38例、对照组 49例，其中观察组采取长臂单轴椎弓根螺钉经 Wiltse入路，对照组采取 AF系统经传统后正中入路。记录两组病人围术期指标、手术前后血清肌肉损伤指标［肌酸激酶( CK)、肌红蛋白( Mb)］变化；采用疼痛视觉模拟评分( VAS)评价病人不同时间节点疼痛水平；经胸腰椎正侧位片检查获取伤椎原始高度( H0)、术前及术后 1周伤椎椎体前缘高度( H1H2)，计算术前、术后 1周伤椎相对高度( H1/H0、H2/H0)及伤椎复位率，并测量矢状位 Cobb角变化；随访 3个月，采用 Oswestry功能障、碍指数( ODI)评价功能障碍情况，并统计手术相关并发症。结果观察组手术时长、术中失血量、术后引流量及首次下床活动时间均明显短于或低于对照组( P<0.05)。术后 3d，两组血清 CK、Mb水平均较术前升高( P<0.05)，且观察组血清 CK、Mb水平     

Machine learning in clinical diagnosis,prognostication, and management of acute traumatic spinal cord injury (SCI): A systematic review

BackgroundMachine learning has been applied to improve diagnosis and prognostication of acute traumatic spinal cord injury. We investigate potential for clinical integration of machine learning in this patient population to navigate variability in injury and recovery.Materials and methodsWe performed a systematic review using PRISMA guidelines through PubMed database to identify studies that use machine learning algorithms for clinical application toward improvements in diagnosis, management, and predictive modeling.ResultsOf the 132 records identified, a total of 13 articles met inclusion criteria and were included in final analysis. Of the 13 articles, 5 focused on diagnostic accuracy and 8 were related to prognostication or management of traumatic spinal cord injury. Across studies, 1983 patients with spinal cord injury were evaluated with most classifying as ASIA C or D. Retrospective designs were used in 10 of 13 studies and 3 were prospective. Studies focused on MRI evaluation and segmentation for diagnostic accuracy and prognostication, investigation of mean arterial pressure in acute care and intraoperative settings, prediction of ambulatory and functional ability, chronic complication prevention, and psychological quality of life assessments. Decision tree, random forests (RF), support vector machines (SVM), hierarchical cluster tree analysis (HCTA), artificial neural networks (ANN), convolutional neural networks (CNN) machine learning subtypes were used.ConclusionsMachine learning represents a platform technology with clinical application in traumatic spinal cord injury diagnosis, prognostication, management, rehabilitation, and risk prevention of chronic complications and mental illness. SVM models showed improved accuracy when compared to other ML subtypes surveyed. Inherent variability across patients with SCI offers unique opportunity for ML and personalized medicine to drive desired outcomes and assess risks in this patient population.

【摘要】 目的：探讨手术治疗脊柱结核病灶清除术后合并感染的疗效分析。方法：回顾性分析2006年1月~2018年12月在我院骨科收治的因脊柱结核术后感染而再次手术的患者的资料18例，其中男性11例，女性7例，年龄27~76岁，平均46.6±18.3岁，随访12~36个月，平均18.6±6.5个月，统计合并症、首次手术方式、致病菌种类、手术时间、术中出血量、术后植骨融和情况等资料，统计手术前、术后2周以及末次随访Cobb角以及C反应蛋白（C-reactive protein，CRP）、血沉、疼痛视觉模拟评分（visual analogue scale，VAS）；根据美国脊髓损伤协会损伤分级（American Spinal Injury Association，ASIA）分析患者手术前及末次随访时的截瘫程度的变化，综合上述因素，评价手术治疗脊柱结核术后感染的疗效分析及相关风险。结果：18例患者中，感染金黄色葡萄球菌4例，大肠埃希菌3例，肺炎克雷伯菌2例，表面葡萄球菌2例，溶血性葡萄球菌2例，厌氧菌1例，铜绿假单胞菌1例，阴沟肠杆菌1例；鲍曼不动杆菌2例。14例采取了单纯后路手术，4例采取了前后路联合的手术。手术时间为97～280min，出血量为100～1200ml。患者术前血沉45.6±25.8mm/h，CRP为38.3±42.0mg/L，VAS评分为6.3±1.5分，Cobb角为15.3°±6.7°；术后2周时血沉30.3±11.0mm/h，CRP为24.1±8.9mg/L，VAS评分2.4±1.2分，Cobb角12.6°±5.8°；末次随访血沉14.2±9.6mm/h，CRP为11.6±13.2mg/L，VAS评分为1.8±1.1分，Cobb角12.8°±4.7°，均有统计学差异（P＜0.05）。1例ASIA B级患者术后恢复至D级、1例ASIA C级患者及4例ASIA D级患者末次随访时ASIA分级达到E级；有1例ASIA D级患者术后仍评为D级，但患者疼痛等症状明显恢复，生活基本自理。术后3～5个月植骨融合率100%。所有患者再次术后未见明显并发症。结论：脊柱结核术后感染的患者，经过充分抗感染、手术中彻底清除病灶、术后充分引流后，也能取得很好的治疗效果。     

芒针对脊髓损伤大鼠运动功能和炎症水平的影响

目的探究芒针深刺秩边穴对大鼠脊髓损伤后运动功能的影响及可能作用机制。方法选择健康雄性Wister大鼠81只,随机分为正常组、模型组和芒针组(正常组9只,其余两组各36只),采用改良Allen's造模法制备大鼠脊髓中度损伤模型,模型组不做特殊处理,芒针组采用芒针深刺秩边穴,每日1次,每次30 min。分别于术后1 d、3 d、5 d、7 d行BBB(Basso-Beattie-Bresnahan)运动功能评分;术后1 d、3 d、5 d、7 d取受损段脊髓组织行酶联免疫吸附测定(ELISA)、实时荧光定量PCR(RT-qPCR)和苏木素-伊红染色(HE染色)。结果术后5 d和7 d,芒针组大鼠BBB评分高于模型组,差异有统计学意义(P<0.01);脊髓损伤后,模型组和芒针组大鼠脊髓组织中高迁移率族蛋白B1(HMGB1)、核转录因子kB(NF-kB)、白介素-6(IL-6)含量及HMGB1mRNA、NF-kBmRNA、IL-6mRNA水平显著升高(P<0.05);受损的脊髓组织松散,灰质中有许多空洞形成,伴有炎性细胞浸润。芒针治疗后,芒针组大鼠脊髓组织中HMGB1、NF-kB、IL-6含量及HMGB1mRNA、NF-kBmRNA、IL-6mRNA水平较模型组降低,且在3 d、5 d、7 d差异有统计学意义(P<0.05);受损部位的空洞及炎性细胞逐渐减少。结论脊髓损伤后,炎症因子的大量聚集引起级联性炎症反应,影响大鼠运动功能的恢复。芒针的抗炎机制可能包括抑制HMGB1的表达,降低NF-kB信号通路的传导,下调促炎因子IL-6的分泌。

Healthcare utilization following spinal cord injury: Objective findings from a regional hospital registry

Objective: The purpose was to describe the prevalence and characteristics of healthcare utilization among individuals with spinal cord injury (SCI) from a Level I trauma center.

Design: Retrospective data analysis utilizing a local acute trauma registry for initial hospitalization and merged with the Dallas-Fort Worth Hospital Council registry to obtain subsequent health care utilization in the first post-injury year.

Setting: Dallas, TX, USA.

Participants: Six hundred and sixty four patients were admitted with an acute traumatic SCI from January 2003 through June 2014 to a Level I trauma center. Fifty five patients that expired during initial hospitalization and 18 patients with unspecified SCI (defined by ICD-9 with no etiology or level of injury specified) were not included in the analysis, leaving a final sample of 591.

Outcome Measures: Data included demographic and clinical characteristics, charges, and healthcare utilization.

Results: Mean age was 46.1?years (±18.9?years), the majority of patients were male (74%), and Caucasian (58%). Of the 591 patients, 345 (58%) had additional inpatient or emergency healthcare utilization accounting for 769 additional visits (median of 3 visits per person). Of the 769 encounters, 534 (69%) were inpatient and 235 (31%) were emergency visits not resulting in an admission. The most prevalent ICD-9 codes listed were pressure ulcer, neurogenic bowel, neurogenic bladder, urinary tract infection, fluid electrolyte imbalance, hypertension, and tobacco use.

Conclusion: Individuals with SCI experience high levels of healthcare utilization which are costly and may be preventable. Increasing our understanding of the prevalence and causes for healthcare utilization after acute SCI is important to target preventive strategies.
