Both clinical and imaging findings are similar and are easily misdiagnosed. This study is to clarify clinical and radiographic finding that could be helpful to differentiate SMS from SIA.Methods: We compared the demographic, clinical, and radiographic characteristics between the SIA and SMS groups. The SIA group (n=13) was diagnosed postoperatively with pathologic confirmation, and the SMS group (n=25) was composed of patients who have a lesion in the spinal cord and met the McDonald criteria for the diagnosis of multiple sclerosis (criteria revised in 2010).Results: Clinically, patients with SIA had a significantly longer symptom duration before the first visit than SMS (4.9±4.4 vs. 2.1±3.6 months, p=0.008). All persons with SIA showed progressive disease course, whereas 95.8% of persons with SMS showed remission (p<0.001). In contrast to SMS, the involvement of both halves of the spinal cord was more frequently observed in patients with SIA (p<0.001). In addition, fusiform dilation in the sagittal plane (p<0.001) or tumoral cyst (p=0.001) also significantly suggested SIA rather than SMS.Conclusion: Despite many limitations of this study, the present data demonstrated the clinical and imaging features helpful in distinguishing SIA from SMS. As with most tumors, SIA tends to show a slowly progressive clinical course without remission. Occupation of both halves of the spinal cord, fusiform dilation, or cysts was favoring radiographic factor for the SIA.","PeriodicalId":229172,"journal":{"name":"The Nerve","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128725054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, spinal abscesses are still unusual and difficult to treat. A 56-year-old woman presented with lower back pain and fever and chills that started two days before the visit. Initially, she showed lower limb extremity motor weakness. There was right focal acute pyelonephritis of the upper kidney portion with an associated complicated cyst on abdominal-pelvic computed tomography. Klebsiella pneumoniae was cultivated in blood and urine cultures. Spine magnetic resonance imaging with contrast enhancement was completed and the results showed epidural and subarachnoid space abscess formation in the whole lumbar space. The patient was treated with total laminectomy at L2-3 and laminotomy at L4-5 with epidural and subarachnoid abscess removal. After surgery, her back pain subsided enough that intravenous morphine was no longer needed. However, lower limb extremity motor weakness was not recovered. Antibiotics were administered to treat a potential cerebral nervous system infection for nine weeks. At the last follow-up, inflammation levels were normalized and the motor weakness in both legs was also normalized with active rehabilitation. This report described an epidural and subarachnoid abscess in a middle-aged woman due to urinary tract infection sepsis associated with acute pyelonephritis caused by Klebsiella pneumoniae. With proper surgery and adequate antibiotic treatment, the patient's symptoms improved significantly without any complications.","PeriodicalId":229172,"journal":{"name":"The Nerve","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133615452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Segmental angle (SA), cervical sagittal alignment (CSA), subsidence, and fusion were evaluated. A visual analogue scale (VAS) and the neck disability index (NDI) were applied pre- and post-operatively and at the last follow-up.Results: Subsidence occurred in 9 (45%) patients and 15 segments (48.4%) at the last follow-up. The mean VAS and NDI scores had improved in both groups with and without subsidence. The mean SA at the last follow-up had significantly increased to 2.3°±8.5° in the subsidence group and to 1.7°± 5.2° degree in the non-subsidence group compared to the post-operative SA (p<0.001). The overall mean CSA at the last follow-up significantly increased overtime in both groups from the postoperative CSA (p=0.003). The fusion rate was 86.7% in the subsidence group and 81.3% in non-subsidence group. However, the difference in SA, CSA and fusion rates between the two groups were not statistically significant (p=0.119, 0.98, and 0.682, respectively).Conclusion: As a result of a long-term follow-up study after stand-alone ACDF, subsidence occurs to some extent. Still, it does not appear to significantly impact radiological and clinical outcomes if the clinician performs sufficient decompression of foramen during surgery. Subsidence seems to have a positive influence on the fusion rate.","PeriodicalId":229172,"journal":{"name":"The Nerve","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126795328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients had clinical or neurophysiological confirmation of CPNe. Among them, 35 (60%) patients underwent axial knee MRI with a 1.5-Tesla scanner. These 35 patients were selected for study and were classified into three groups according to the time of examination after the occurrence of dropped foot―acute, subacute, and chronic onset groups. According to muscle appearances (normal, edematous change, and atrophy), we diagnosed them with CPNe, except for those with normal morphology. We evaluated the applicability of MRI in the diagnosis of CPNe compared to that of electromyography (EMG).Results: The 18, 11, and six cases were included in the acute, subacute, and chronic onset groups, respectively. In the acute onset group, three cases had normal muscle appearance, while 15 cases had edematous changes in the affected muscles. In the subacute onset group, eight cases had edematous changes, while three cases showed muscle atrophy. In the chronic onset group, six cases had muscle atrophy. CPNe could be diagnosed using MRI in about 91% (32/35) of all the cases. Excluding the chronologically chronic stage, diagnosis rate was approximately 89%(26/29) of all the cases. However, only in 27 cases (77%) denervation potentials were presented on EMG.Conclusion: According to our results, MRI is a helpful diagnostic modality, especially in the early stage of CPNe, and may lead to proper management.","PeriodicalId":229172,"journal":{"name":"The Nerve","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114829801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, quantitative computed tomography (QCT) measures the BMD more accurately by directly measuring the trabecular bone. This study examined the factors that cause the discrepancy between DXA and QCT with advanced spinal imaging.Methods: The medical records of 59 patients who underwent DXA, QCT, and a lumbar spine magnetic resonance imaging (MRI) were reviewed retrospectively. The following values were measured on plain radiographs, computed tomography, and MRI: lumbar lordosis, segmental scoliosis, compression fracture, spondylosis, abdominal aortic calcification, facet joint degeneration, and Modic change. The significant parameters contributing to the discordance results between DXA and QCT were evaluated by logistic regression analysis.Results: QCT identified osteoporosis in 43 patients (72.88%). DXA identified 15 osteoporotic patients (25.42%). Of the 44 patients not diagnosed with osteoporosis by DXA, 30 patients (68.18%) were diagnosed with osteoporosis by QCT. Multivariate logistic regression analysis showed that the result of DXA might be overestimated by a degenerated facet joint (odds ratio [OR] 4.58; 95% confidence interval [CI], 1.1-19.07) and measurements at a fracture site (OR, 1.63; 95% CI, 1.23-2.15).Conclusion: DXA might miss a diagnosis of osteoporosis. Facet joint hypertrophy due to degeneration revealed a stronger association with the overestimation of the BMD by DXA than the formation of osteophytes at the vertebral body. Therefore, the results of DXA should be interpreted carefully, considering the possibility of interruption.","PeriodicalId":229172,"journal":{"name":"The Nerve","volume":"273 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124515456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-three patients with SAI screw fixation and 25 with CI screw fixation were included. Preoperative patient and surgical characteristics and postoperative outcomes and complications were analyzed between the SAI and CI groups. Radiographic parameters were analyzed before and after surgery.Results: Lumbosacral fusion rates showed no statistically significant difference between the SAI group and CI groups (90.7% vs. 92.0%, p=0.878). The SAI group showed a significantly good result with regard to SSI compared to the CI group (0% vs. 16%, p=0.016), but had a significantly higher rate of distal screw fracture than the CI group (16.3% vs. 0%, p=0.042).Conclusion: The SAI screw fixation technique could achieve good outcomes of pain relief, deformity correction, and lumbosacral fusion rate with relatively lower complications such as the rates of reoperation, SSI, and screw prominence as compared to the CI screw fixation technique.
