BACKGROUND
Spinal cord ischemia (SCI) is one of the most devastating complications of thoracic endovascular aortic repair (TEVAR). Prophylactic cerebrospinal fluid drainage (CSFD) has been shown to decrease the risk of SCI in open thoracic aortic procedures; however, its utility in TEVAR remains uncertain. This systematic review and meta-analysis aim to determine the role of prophylactic CSFD in preventing SCI in TEVAR.
METHODS
A literature search of five databases was performed and all studies published before September 2022 that reported SCI rates in TEVAR patients undergoing prophylactic CSFD were included. A random effects meta-analysis of means or proportions was performed for single-arm data. Odds ratios (ORs) with 95% confidence intervals (CIs) were reported for comparisons between groups.
RESULTS
A total of 4,793 patients undergoing TEVAR from 40 studies were included. The mean age was 68.8 years and 70.9% of patients were male. The overall SCI rate was 3.5%, with a 1.3% rate of immediate SCI and a 1.9% rate of delayed SCI. There were no significant differences in SCI rates between prophylactic CSFD patients and non-drained patients. Routine CSFD did not have a significant impact on SCI rates compared to non-drained patients. There was an increased rate of transient SCI with selective CSFD compared to non-drained patients (OR 2.08; 95% CI: 1.06-4.08; P=0.03). The most common drain-related complication was spinal headache (4.3%). The major complication rate was 1.6%, of which epidural or spinal hematoma (0.9%) was the most common, followed by intracranial or subdural hemorrhage (0.8%) and paraparesis or paraplegia (0.8%).
CONCLUSIONS
This study found no significant difference in SCI rates between prophylactic CSFD patients and their non-drained counterparts. CSFD is associated with a small but non-negligible risk of serious complications. Multi-center randomized controlled trials (RCTs) are warranted to help stratify the risk of both SCI and CSFD-related complications in patients undergoing endovascular aortic procedures.

INTRODUCTION AND IMPORTANCE
Solitary spinal plasmacytoma (SSP) is an uncommon neoplasm originating from bone marrow plasma cells. Although infrequent in the thoracic region, it has the potential to induce substantial damage. In this study, we present the case of a patient with thoracic spine SSP treated through surgical intervention.
CASE PRESENTATION
We report the case of a 38-year-old female who presented with progressive mid-back pain, numbness, weakness in both lower limbs and gait disturbance. Imaging showed an osteolytic lesion with vertebral collapse of T11. MRI was strongly suggestive of solitary plasmocytoma. Hematologic tests were normal. Surgery was carried out. At the first stage, a posterior approach with laminectomy and fixation were performed. Biopsy of tumor cells confirmed the diagnosis of SSP. At the second stage, a trans-thoracic approach was performed, the tumor was resected in a single block and anterior interbody fusion was done. After the surgery the patient fully recovered from the paraparesis and at two years follow up no recurrence of tumor cells was detected.
CLINICAL DISCUSSION
Spinal malignant bone tumors are rare, with solitary plasmacytoma being the most common. Diagnosis of SSP is based on bone biopsy findings. MRI and CT scans assess tumor extent and spinal stability. Prognosis relates to the likelihood of progressing into multiple myeloma. Though radiotherapy is common, surgery offers local control, especially for instability and neurological issues.
CONCLUSION
SSP in the thoracic spine is a rare condition that requires a multidisciplinary approach and a prompt treatment.

Paraparesis following cardiac surgery is a manifestation of spinal cord injury (SCI). It can occur in any aortic surgery from the aneurysm to the coarctation of the aorta (CoA) where the cross-clamp of the aorta is applied. Though the incidence of paraplegia is low, its occurrence affects the morbidity and mortality of the patient. There are only sporadic case reports on the development of paraplegia following recurrent and technically challenging repair of CoA. However, the spontaneous development of paraplegia has also been reported in cases of unoperated CoA. The present report describes the case of delayed SCI in which paraparesis developed 5 days post a coarctation repair. The risk factors and strategies to protect the spinal cord during aortic surgeries are emphasized.

CASE SERIES SUMMARY
A 1-year-old castrated male Maine Coon cat was referred because of a 1-week history of progressive spastic non-ambulatory paraparesis. An MRI examination of the thoracolumbar spine showed multiple lytic lesions, with the most aggressive one centred on the adjacent endplates of L1-L2 and its associated disc. Ventral new bone formation, L1 vertebral body shortening and mild dorsal displacement of the caudal aspect of L1 were noted. Contrast enhancement of both paravertebral soft tissue and extradural lesion was present. These findings were compatible with L1-L2 discospondylitis (DS), spinal epidural empyema (SEE), with secondary L1 pathological vertebral fracture, subluxation and spinal cord compression. CT of the thoracolumbar spine, abdomen and thorax confirmed these findings. The patient deteriorated to paraplegia with absent nociception, despite initial medical therapy. A right-sided L1-L2 hemilaminectomy and spinal decompression were then performed, followed by application of a unilateral construct comprising four smooth arthrodesis wires and polymethylmethacrylate (PMMA). S was isolated from both epidural material, intraoperatively sampled and blood culture. Antibiotic therapy was continued for 6 weeks, based on susceptibility results. The outcome was excellent, with a gradual improvement and complete neurological recovery at the 8-week postoperative check. Repeated spinal radiographs showed an intact apparatus and marked signs of vertebral fusion. At the 14-month follow-up examination, the cat remained free of clinical signs.
RELEVANCE AND NOVEL INFORMATION
To the authors' knowledge, this is the first case report of SEE and DS in a cat that required surgical stabilisation. The outcome was still optimal, despite the rapid neurological deterioration.

INTRODUCTION
Infection with human T cell lymphotropic virus type 1 (HTLV-1) is endemic in Brazil and is linked with pro-inflammatory conditions including HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), a chronic neuroinflammatory incapacitating disease that culminates in loss of motor functions. The mechanisms underlying the onset and progression of HAM/TSP are incompletely understood. Previous studies have demonstrated that inflammation and infectious agents can affect the expression of cellular prion protein (PrP) in immune cells.
METHODS
Here, we investigated whether HTLV-1 infection affected PrP content in cell lines and primary CD4cells using flow cytometry and western blot assays.
RESULTS
We found that HTLV-1 infection decreased the expression levels of PrP and HTLV-1 encoded p12, an endoplasmic reticulum resident protein also known to affect post-transcriptionally cellular proteins such as MHC-class I and the IL-2 receptor. In addition, we observed a reduced percentage of CD4 T cells from infected individuals expressing PrP, which was reflected by IFN type II but not IL-17 expression.
DISCUSSION
These results suggested that PrP downregulation, linked to both HTLV-1 p12 and IFN-γ expression in CD4 cells, may play a role in the neuropathogenesis of HTLV-1 infection.

BACKGROUND
Our study presents a single-center experience of resection of intradural spinal tumors either with or without using intraoperative computed tomography-based registration and microscope-based augmented reality (AR). Microscope-based AR was recently described for improved orientation in the operative field in spine surgery, using superimposed images of segmented structures of interest in a two-dimensional or three-dimensional mode.
METHODS
All patients who underwent surgery for resection of intradural spinal tumors at our department were retrospectively included in the study. Clinical outcomes in terms of postoperative neurologic deficits and complications were evaluated, as well as neuroradiologic outcomes for tumor remnants and recurrence.
RESULTS
112 patients (57 female, 55 male; median age 55.8 ± 17.8 years) who underwent 120 surgeries for resection of intradural spinal tumors with the use of intraoperative neuromonitoring were included in the study, with a median follow-up of 39 ± 34.4 months. Nine patients died during the follow-up for reasons unrelated to surgery. The most common tumors were meningioma (n = 41), schwannoma (n = 37), myopapillary ependymomas (n = 12), ependymomas (n = 10), and others (20). Tumors were in the thoracic spine (n = 46), lumbar spine (n = 39), cervical spine (n = 32), lumbosacral spine (n = 1), thoracic and lumbar spine (n = 1), and 1 tumor in the cervical, thoracic, and lumbar spine. Four biopsies were performed, 10 partial resections, 13 subtotal resections, and 93 gross total resections. Laminectomy was the common approach. In 79 cases, patients experienced neurologic deficits before surgery, with ataxia and paraparesis as the most common ones. After surgery, 67 patients were unchanged, 49 improved and 4 worsened. Operative time, extent of resection, clinical outcome, and complication rate did not differ between the AR and non-AR groups. However, the use of AR improved orientation in the operative field by identification of important neurovascular structures.
CONCLUSIONS
High rates of gross total resection with favorable neurologic outcomes in most patients as well as low recurrence rates with comparable complication rates were noted in our single-center experience. AR improved intraoperative orientation and increased surgeons' comfort by enabling early identification of important anatomic structures; however, clinical and radiologic outcomes did not differ, when AR was not used.

Feline arterial thromboembolism has been reported to be secondary to various feline cardiomyopathies; however, it has not been described in cats with transient myocardial thickening. A previously healthy, one-year-old, castrated male cat presented with acute paraparesis and congestive heart failure. Echocardiography revealed asymmetric left ventricular free wall thickening and left atrial enlargement. Antithrombotic treatment and cardiac medication resulted in reperfusion and mobility on day seven in one limb and on day 10 in the other. Different complications were managed successfully, including worsening acute kidney injury, inflammation, pleural effusion, and anemia. After three weeks, the cat was discharged and prescribed oral antithrombotic drugs (clopidogrel and rivaroxaban) and cardiac medication. Within five months, echocardiographic findings normalized, and medical treatment was gradually discontinued. To date, the cat remains healthy at 1735 days after the initial diagnosis and 1494 days after the last antithrombotic medication. To the best of our knowledge, this is the first case report on feline arterial thromboembolism combined with transient myocardial thickening, with favorable long-term survival.

Multidrug-resistant tuberculous spondylitis is a global health issue, especially in developing nations, and non-specific symptoms lead to delay in identification, treatment, and potential disability in children. Radiology plays a crucial role in diagnosing tuberculous spondylitis, which in turn might lead to effective treatment, prevention of disability and improved patient outcomes. Our case involved a 20-month-old malnourished child presented with paraparesis, revealing a history of contact with parental multidrug-resistant tuberculosis. Multimodality radiological examinations, including conventional radiography, CT, and MRI revealed extensive disease of the spine with disc involvement, large paravertebral abscess, and kyphotic deformity which produced neurological deficits, necessitating both anti-tuberculosis regimen and surgical intervention. Radiological examinations have a pivotal role in diagnosing, evaluating and guiding timely management of multidrug-resistant tuberculous spondylitis. Prompt diagnosis of the condition is crucial in order to prevent potentially severe complications, which contribute significantly to morbidity. Our case demonstrated the importance of radiology in diagnosing extensive spine involvement of the disease causing neurological deficits. Furthermore, radiology also helps in managing tuberculous spondylitis to prevent future disability in a child patient of a developing country. This case highlights the crucial significance of radiological imaging in the diagnosis and management of pediatric tuberculous spondylitis in impoverished nations. The patient's complex medical history highlights the socioeconomic factors contributing to tuberculosis burden. Early and comprehensive radiological assessment, together with collaboration between radiologists and clinicians, is vital for timely intervention and improved outcomes in pediatric tuberculous spondylitis cases to prevent the impact of this debilitating disease on children.

Review
We report the case of a 42-year-old woman with paraparesis associated with transverse myelitis. For differential diagnostics detailed microbiological, cerebrospinal fluid (CSF) and neuroimaging examinations were performed. Syphilis was confirmed, but diagnosis of neurosyphilis was only probable based on the CSF microbiological test results. The beneficial treatment response to application of the therapeutic protocol for syphilis supported the supposed diagnosis of syphilis-associated myelitis in our case. In this case report we reviewed the differential diagnostic tools of myelopathies/myelitis.

Randomized Controlled Trial
Multicenter, randomized, double-blind, placebo-controlled phase 3 study of mogamulizumab with open-label extension study in a minimum number of patients with human T-cell leukemia virus type-1-associated myelopathy.
Human T-cell leukemia virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic neurodegenerative disease. This multicenter, randomized phase 3 study evaluated the efficacy and safety of 0.3 mg/kg intravenous mogamulizumab, a monoclonal antibody targeting-CC chemokine receptor 4, every 12 weeks in HAM/TSP patients. This study comprised a 24-week double-blind, placebo-controlled period, 24-week open-label period, and extension treatment period. The primary endpoint was the proportion of patients with a ≥ 1-grade improvement in the Osame motor disability score (OMDS). Secondary endpoints were changes in HTLV-1 proviral load, 10-m timed walk, cerebrospinal fluid (CSF) neopterin levels, and safety. The exploratory endpoint was CSF chemokine C-X-C motif ligand 10 (CXCL10) levels. Thirty-four and 33 patients were randomized to mogamulizumab and placebo arms, respectively. At the end of the double-blind period, no significant difference was found in the OMDS improvement rate or other secondary efficacy endpoints assessing motor activities. However, the mogamulizumab arm showed a significant decrease in HTLV-1 proviral load (- 59.39 ± 29.91% vs. placebo 2.32 ± 36.31%) and CSF neopterin (p < 0.001)/CXCL10 levels (p = 0.004). The baseline OMDS pattern and the 60-80% HTLV-1 proviral load reduction were sustained through the open-label and extension treatment periods. Although a higher incidence of rash (69.2%) was reported, the safety profile was similar compared with a previous phase 1/2a study. We found no significant difference in clinical benefit; however, mogamulizumab may provide long-term clinical benefit by preventing disease progression, as CSF neopterin/CXCL10 levels are associated with long-term prognosis in HAM/TSP.Clinical Trial Registration Number: NCT03191526 (registered date: 6-June-2017).
