Methods: From June 2011 to August 2016, 24 patients with mono-segmental thoracic spine tuberculosis were treated by transfacet debridement combined with bone grafting and internal fixation through paraspinal approach. There were 11 males and 13 females with age ranging from 21 to 63 years (average, 39.5). There were 3 patients in T4/5, 2 patients in T5/6, 3 patients in T7/8, 3 patients in T8/9, 4 patients in T9/10, 3 patients in T10/11, and 6 patients in T11/12. Patients had different degraded local kyphosis deformity shown on X-ray, and different degraded bone destruction and abscess in thoracic spine shown on CT and MRI before the operation. All of the patients before the regular anti tuberculosis treatment for 2 to 4 weeks, the surgical approach used by paraspinal muscle approach, postoperative regular anti tuberculosis treatment for 9 to 12 weeks. Record the clinical symptoms of patients before and after surgery, preoperative Frankel functional classification of spinal cord injury, the operative time, intraoperative blood loss, postoperative ESR, CRP, complications, VAS score, ODI score and Cobb angle changes, imaging check regularly to evaluate the fusion and follow-up of nerve functional recovery. Results: The average operation time was 198 min. The average blood loss was 436 ml. There were no severe complications during and after operation. All patients were followed up for 1 year to 2 years, average 1.5 years of follow-up, the clinical symptoms improved significantly after operation and last follow-up ESR, CRP, VAS score, ODI score and Cobb angle were significantly improved after operation (P < 0.05), grade I Eck fusion, the fusion rate was 100% and the neurological function were improved. Conclusion: on the basis of strict anti tuberculosis chemotherapy, the use of paraspinal muscle gap approach for the treatment of thoracic tuberculosis is less invasive, less destructive to spinal stability, and can achieve obvious curative effect. It is worthy of clinical application.展开更多

Twenty-four patients with thoracic or lumbar spinal tuberculosis whose lesions were confined to adjacent segments were admitted to our hospital and treated. The American Spinal Injury Association（ASIA） impairment scale was used to assess the neurological function. All patients were treated with one-stage surgical treatment via a posterior-only approach. The clinical efficacy was evaluated by the Japanese Orthopaedic Association（JOA） scores and oswestry disability index（ODI） of nerve function. Patients were evaluated preoperatively and postoperatively by measurement of spinal deformity using Cobb angle and radiological examination. All the patients were followed up for 13 to 27 months. They had significantly postoperative improvement in JOA score, ODI and ASIA classification scores. The kyphotic angles were significantly corrected and maintained at the final follow-up. Bone fusion was achieved within 4–12 months. It was concluded that one-stage surgical treatment via a posterior-only approach is effective and feasible for the treatment of spinal tuberculosis.展开更多

The aim of this study was to investigate the diagnosis and treatment of spinal tuberculosis after organ transplantation. METHOD: Two cases were diagnosed as spinal tuberculosis after liver transplantation and were treated with socarboxazide, rifampicin, streptomycin and ethambutol for more than one year. RESULTS: After treatment with anti-tuberculosis drugs for several months, the symptoms of both patients clearly improved. Back pain disappeared, and erythrocyte sedimentation and body temperature returned to normal. CONCLUSIONS: We should highly suspect spinal tuberculosis if notalgia and night sweats are present after organ transplantation. Anti-tuberculosis therapy is an effective treatment for spinal tuberculosis after organ transplantation.展开更多

The clinical manifestations of spinal intramedullary TB aresimilar to those of intramedullary spinal cord tumors. Therefore, it is necessary tomake a careful differential diagnosis of spinal intramedullary lesions to achievethe appropriate treatment and favorable prognosis. We report a rare case of ayoung male patient with paraplegia due to spinal intramedullary TB, which isuncommon and regrettable.CASE SUMMARY A 23-year-old male presented with fever accompanied by nausea and vomitinglasting for 2 mo and was then diagnosed with tubercular meningitis. After anti-TBtreatment, his symptoms were significantly improved. However, 2 mo after thediagnosis of tubercular meningitis, the patient felt numbness below the costal archlevel, which lasted for 1 wk, and he paid no attention to this symptom. Whatfollowed was paraplegia and urine/fecal incontinence. Magnetic resonanceimaging of the thoracic spine showed a ring-enhanced intramedullary cord lesionat T8-T9. Lesion exploration showed enlargement of the spinal cord at T8-T9, andthe lesion could be observed by incision. The lesion was adhered to the peripheraltissue and was grayish-white and tough with a poor blood supply and a diameterof approximately 0.8 cm. The lesion was resected completely. The results ofpathological examination by both hematoxylin-eosin staining and acid-fast bacillistaining confirmed TB, accompanied by acute and chronic suppurativeinflammation and granulation tissue formation. The patient was instructed tocontinue anti-TB treatment after the operation, but he did not follow the medicaladvice. Follow-up continued for ten years, the patient had persistent paraplegia,the numbness disappeared and urine/fecal sensation recovered.CONCLUSION Although TB is a kind of benign disease, some cases progress rapidly. Moreover,spinal intramedullary TB may seriously endanger quality of life and still needstimely diagnosis and proper treatment.展开更多

文摘Spinal cord injury(SCI)interrupts the flow of information between the brain and the spinal cord,thus leading to a loss of sensory information and motor paralysis of the body below the lesion.Surprisingly,most SCIs are incomplete and spare supraspinal pathways,especially those located within the peripheral white matter of the spinal cord,which includes reticulospinal pathways originating from the medullary reticular formation.Whereas there is abundant literature about the motor cortex,its corticospinal pathway,and its capacity to modulate functional recovery after SCI,less is known about the medullary reticular formation and its reticulospinal pathway.
文摘Objective: To evaluate the clinical feasibility and efficacy in treatment of thoracic tuberculosis via paraspinal approach. Methods: From June 2011 to August 2016, 24 patients with mono-segmental thoracic spine tuberculosis were treated by transfacet debridement combined with bone grafting and internal fixation through paraspinal approach. There were 11 males and 13 females with age ranging from 21 to 63 years (average, 39.5). There were 3 patients in T4/5, 2 patients in T5/6, 3 patients in T7/8, 3 patients in T8/9, 4 patients in T9/10, 3 patients in T10/11, and 6 patients in T11/12. Patients had different degraded local kyphosis deformity shown on X-ray, and different degraded bone destruction and abscess in thoracic spine shown on CT and MRI before the operation. All of the patients before the regular anti tuberculosis treatment for 2 to 4 weeks, the surgical approach used by paraspinal muscle approach, postoperative regular anti tuberculosis treatment for 9 to 12 weeks. Record the clinical symptoms of patients before and after surgery, preoperative Frankel functional classification of spinal cord injury, the operative time, intraoperative blood loss, postoperative ESR, CRP, complications, VAS score, ODI score and Cobb angle changes, imaging check regularly to evaluate the fusion and follow-up of nerve functional recovery. Results: The average operation time was 198 min. The average blood loss was 436 ml. There were no severe complications during and after operation. All patients were followed up for 1 year to 2 years, average 1.5 years of follow-up, the clinical symptoms improved significantly after operation and last follow-up ESR, CRP, VAS score, ODI score and Cobb angle were significantly improved after operation (P < 0.05), grade I Eck fusion, the fusion rate was 100% and the neurological function were improved. Conclusion: on the basis of strict anti tuberculosis chemotherapy, the use of paraspinal muscle gap approach for the treatment of thoracic tuberculosis is less invasive, less destructive to spinal stability, and can achieve obvious curative effect. It is worthy of clinical application.
文摘This study examined the clinical outcomes of one-stage surgical treatment for patients with spinal tuberculosis via a posterior-only approach. Twenty-four patients with thoracic or lumbar spinal tuberculosis whose lesions were confined to adjacent segments were admitted to our hospital and treated. The American Spinal Injury Association（ASIA） impairment scale was used to assess the neurological function. All patients were treated with one-stage surgical treatment via a posterior-only approach. The clinical efficacy was evaluated by the Japanese Orthopaedic Association（JOA） scores and oswestry disability index（ODI） of nerve function. Patients were evaluated preoperatively and postoperatively by measurement of spinal deformity using Cobb angle and radiological examination. All the patients were followed up for 13 to 27 months. They had significantly postoperative improvement in JOA score, ODI and ASIA classification scores. The kyphotic angles were significantly corrected and maintained at the final follow-up. Bone fusion was achieved within 4–12 months. It was concluded that one-stage surgical treatment via a posterior-only approach is effective and feasible for the treatment of spinal tuberculosis.
文摘BACKGROUND: Spinal tuberculosis is a common disease in orthopedic clinical practice; however, it is seldom reported after organ transplantation. The aim of this study was to investigate the diagnosis and treatment of spinal tuberculosis after organ transplantation. METHOD: Two cases were diagnosed as spinal tuberculosis after liver transplantation and were treated with socarboxazide, rifampicin, streptomycin and ethambutol for more than one year. RESULTS: After treatment with anti-tuberculosis drugs for several months, the symptoms of both patients clearly improved. Back pain disappeared, and erythrocyte sedimentation and body temperature returned to normal. CONCLUSIONS: We should highly suspect spinal tuberculosis if notalgia and night sweats are present after organ transplantation. Anti-tuberculosis therapy is an effective treatment for spinal tuberculosis after organ transplantation.

文摘Spinal tuberculosis,as one of the most serious forms of extrapulmonary tuberculosis,is one of the primary causes of spinal deformity and paralysis in developing countries.It immensely affects people's quality of life with high incidences of deformity and disability.The onset of spinal tuberculosis is related to many factors such as gender,age,environment,habits and hereditary factor.As a genetic factor,gene polymorphism plays an important role in the occurrence and development of tuberculosis.This article reviews the research progress of the susceptibility of spinal tuberculosis and its related gene polymorphisms,in order to provide reference for early prevention and treatment of spinal tuberculosis.
文摘Objective:To investigate the effect of intensive psycho1ogical nursing on the mood and coping ways of spinal tuberculosis patients.Methods:The clinical data of 102 patients undergoing spinal tuberculosis surgery in our hospital from February 2017 to January 2020 were retrospectively analyzed.A11 the cases were grouped according to different nursing plans,patients who received routine care were included in the control group(n=50),and the ones with intensive psychological care were included in the observation group(n=52).Compare negative emotions after nursing[assessment using self-assessment scale of anxiety(SAS),depression self-assessment scale(SDS)]and solutions[assessment using medical response questionnaire(MCMQ)]of the two groups.Results:After nursing,the SAs,SDs scores,avoidance and yield scores of the two groups were reduced,and the coping scores were increased,and the change of the observation group was greater than that of the control group,the difference was statistically significant(P<0.05).Conclusion:Spinal tuberculosis surgery patients were treated with intensive psychological care,which can relieve patients'negative emotions,improve solutions and are worthy of clinical use.
文摘Objective: to explore and analyze the clinical value of CT and MRI in the diagnosis of spinal tuberculosis. Methods: a total of 48 patients with spinal tuberculosis admitted to our hospital from January to December 2020 were selected for the study. All patients received CT and MRI imaging diagnosis successively, and the results of the two imaging examinations were compared and analyzed. Results: the diagnosis results of the two methods for bone disc loss and paravertebral mass are exactly the same, P > 0.05. The detection rate of ligament diffusion, dural cyst and meningeal enhancement by MRI was significantly higher than that by CT, while the detection rate of calcification was significantly lower than that by CT, P<0.05. Conclusion: in the clinical diagnosis of spinal tuberculosis, both CT and MIR have high application value and the diagnostic accuracy of MIR is relatively higher.

文摘Human spinal cord organoids(hSCOs)offer a promising platform to study neurotrauma by addressing many limitations of traditional research models.These organoids provide access to human-specific physiological and genetic mechanisms and can be derived from an individual's somatic cells(e.g.,blood or skin).This enables patient-specific paradigms for precision neurotrauma research,pa rticula rly relevant to the over 300,000 people in the United States living with chronic effects of spinal cord injury(SCI).
文摘BACKGROUND Spinal epidural abscess(SEA)is a rare condition that mostly results from infection with either bacteria or tuberculosis.However,coinfection with bacteria and tuberculosis is extremely rare,and it results in delays in diagnosis and antimicrobial treatment causing unfavorable outcomes.CASE SUMMARY A 75-year-old female visited the hospital with low back pain,and magnetic resonance imaging(MRI)revealed an SEA at the lumbosacral segment.Staphylococcus hominis and methicillin-resistant Staphylococcus epidermidis were identified from preoperative blood culture and intraoperative abscess culture,respectively.Thus,the patient underwent treatment with vancomycin medication for 9 wk after surgical drainage of the SEA.However,the low back pain recurred 2 wk after vancomycin treatment.MRI revealed an aggravated SEA in the same area in addition to erosive destruction of vertebral bodies.Second surgery was performed for SEA removal and spinal instrumentation.The microbiological study and pathological examination confirmed Mycobacterium tuberculosis as the pathogen concurrent with the bacterial SEA.The patient improved completely after 12 mo of antitubercular medication.CONCLUSION We believe that the identification of a certain pathogen in SEAs does not exclude coinfection with other pathogens.Tubercular coinfection should be suspected if an SEA does not improve despite appropriate antibiotics for the identified pathogen.
文摘BACKGROUND Tuberculosis (TB) mostly attacks the lungs, and extrapulmonary TB involving thecentral nervous system is uncommon;among these cases, spinal intramedullaryTB is even more rare. The clinical manifestations of spinal intramedullary TB aresimilar to those of intramedullary spinal cord tumors. Therefore, it is necessary tomake a careful differential diagnosis of spinal intramedullary lesions to achievethe appropriate treatment and favorable prognosis. We report a rare case of ayoung male patient with paraplegia due to spinal intramedullary TB, which isuncommon and regrettable.CASE SUMMARY A 23-year-old male presented with fever accompanied by nausea and vomitinglasting for 2 mo and was then diagnosed with tubercular meningitis. After anti-TBtreatment, his symptoms were significantly improved. However, 2 mo after thediagnosis of tubercular meningitis, the patient felt numbness below the costal archlevel, which lasted for 1 wk, and he paid no attention to this symptom. Whatfollowed was paraplegia and urine/fecal incontinence. Magnetic resonanceimaging of the thoracic spine showed a ring-enhanced intramedullary cord lesionat T8-T9. Lesion exploration showed enlargement of the spinal cord at T8-T9, andthe lesion could be observed by incision. The lesion was adhered to the peripheraltissue and was grayish-white and tough with a poor blood supply and a diameterof approximately 0.8 cm. The lesion was resected completely. The results ofpathological examination by both hematoxylin-eosin staining and acid-fast bacillistaining confirmed TB, accompanied by acute and chronic suppurativeinflammation and granulation tissue formation. The patient was instructed tocontinue anti-TB treatment after the operation, but he did not follow the medicaladvice. Follow-up continued for ten years, the patient had persistent paraplegia,the numbness disappeared and urine/fecal sensation recovered.CONCLUSION Although TB is a kind of benign disease, some cases progress rapidly. Moreover,spinal intramedullary TB may seriously endanger quality of life and still needstimely diagnosis and proper treatment.

文摘Background:Skeletal tuberculosis(TB)remains a persistent clinical and research chal-lenge due to its chronic course,osteolytic destruction,and the limitations of existing animal models,which often require high-level biosafety containment or fail to repli-cate human skeletal pathology.Methods:This study developed a biosafe,accessible,and versatile murine model of skeletal TB using Mycobacterium smegmatis,a fast-growing,nonpathogenic myco-bacterial species with high genomic homology to Mycobacterium tuberculosis.Three infection routes-subperiosteal calvarial injection,intratibial injection,and intra-cardiac inoculation-were systematically evaluated for their ability to induce lo-calized versus disseminated bone infection under standard biosafety level(BSL)-1 conditions.Results:Subperiosteal calvarial and intratibial injection of M.smegmatis induced local-ized bone lesions characterized by osteolysis,sequestrum formation,granulomatous inflammation,and increased osteoclast activity.Intratibial infection additionally trig-gered compartment-specific immune responses,including neutrophil and macrophage expansion,transient B-cell depletion,and activation of interferon-γ^(+)(IFN-γ^(+))T cells,reflecting active immune remodeling at the infection site.Systemic dissemination via intracardiac injection reproducibly generated progressive vertebral and tibial bone destruction with organized granuloma formation and immune cell infiltration but without prominent sequestrum formation.Compared to intratibial infection,intracar-diac delivery exhibited lower intragroup variability and more closely recapitulated the diffuse progression of extrapulmonary skeletal tuberculosis.Conclusions:This M.smegmatis-based murine model provides a straightforward,reliable,and immunopathologically relevant platform for exploring host-pathogen dynamics,immune-driven bone destruction,and early-stage therapeutic testing in skeletal TB,all within standard BSL-1 laboratories.This model fills a critical gap by enabling BSL-1 research into skeletal TB mechanisms and drug development.

文摘BACKGROUND Tuberculous osteitis is a chronic,granulomatous bone infection that frequently results in impaired bone healing following surgery.Despite surgical intervention and prolonged anti-tuberculous therapy,complete bone regeneration often remains unachieved,contributing to subsequent orthopedic complications.AIM To investigate the efficacy and safety of pamidronate in promoting bone regeneration following surgical treatment of experimental animal tuberculous osteitis.METHODS A controlled randomized basic study of rabbit femoral tuberculosis induced by Mycobacterium tuberculosis strain H37Rv included surgical removal of infected tissue and implantation of osteoinductive bone grafts with the following animal allocation to one of three groups:(1)Bisphosphonates alone;(2)Bisphosphonates combined with anti-tuberculous therapy;and(3)Anti-tuberculous therapy alone.The control group consisted of animals that received no surgical or medical treatment.Clinical evaluations,biochemical markers,micro-computed tomography imaging,and histomorphometry analyses were conducted at 3 months and 6 months postoperatively.RESULTS Pamidronate treatment significantly reduced early implant resorption,increased osteoblastic activity,improved trabecular bone regeneration,and maintained graft integrity compared to the anti-tuberculous therapy-only group.Histologically,pamidronate led to enhanced vascular remodeling and increased bone matrix formation.Crucially,bisphosphonate therapy demonstrated safety,compatibility with anti-tuberculous medications,and did not exacerbate tuberculous inflammation.Furthermore,micro-computed tomography analysis revealed a significant increase in trabecular thickness and density in pamidronate-treated groups,underscoring the anabolic effects of bisphosphonates.Morphometric evaluation confirmed a marked reduction in osteoclast number and activity at graft interfaces.These combined radiological,histological,and biochemical data collectively demonstrate the efficacy of pamidronate as an adjunctive agent in enhancing bone repair outcomes following surgical intervention for tuberculous osteitis.CONCLUSION A single intravenous dose of pamidronate significantly enhances bone regeneration and prevents implant resorption following surgical treatment of tuberculous osteitis.The following prospective studies are needed.
文摘Spinal cord injury(SCI) often results in permanent dysfunction of locomotion,sensation,and autonomic regulation,imposing a substantial burden on both individuals and society(Anjum et al.,2020).SCI has a complex pathophysiology:an initial primary injury(mechanical trauma,axonal disruption,and hemorrhage) is followed by a progressive secondary injury cascade that involves ischemia,neuronal loss,and inflammation.Given the challenges in achieving regeneration of the injured spinal cord,neuroprotection has been at the forefront of clinical research.

文摘Spinal cord injury(SCI)is a debilitating ailment that leads to the loss of motor and sensory functions,often leaving the patient paralyzed below the injury site(Chen et al.,2013).Globally around 250,000-300,000 people are diagnosed with SCI annually(Singh et al.,2014),and while this number appears quite low,the effect that an SCI has on the patient’s quality of life is drastic,due to the current difficulties to comprehensively treat this illness.The cost of patient care can also be quite costly,amounting to an estimated$1.69 billion in healthcare costs in the USA alone(Mahabaleshwarkar and Khanna,2014).
