Pott's disease in Abidjan: experience of the department of rheumatology of university teaching hospital of Cocody: about 420 cases

INTRODUCTION

Pott's disease continues to be rife primarily in ivorian's setting. This large-scale study presents the Ivorian experience in the management of this disease.

AIM

To determine the epidemiological, clinical, paraclinical, therapeutic and evolutionary profile of Pott's disease in Abidjan and to identify the factors associated with neurological compressions.

METHODS

Retrospective and analytical study of 420 files of patients suffering from presumptive or confirmed Pott's disease, hospitalized in the rheumatology department of Cocody University Hospital from January 2010 to December 2019.

RESULTS

The hospital frequency of tuberculous spondylodiscitis was 10.2%. Our study population consisted of 223 men and 197 women with an average age of 43.8 ± 15.5 years. A tuberculosis history and a notion of tuberculosis contagion were noted in 4.3% and 13.8% of cases respectively. The mean diagnostic time was 9.67 ± 10.11 months. The main clinical data were spinal syndrome (98.80%) and also tuberculous impregnation signs (84.76%). Neurological complications were noted in 11.66% of cases. Bacilloscopy and PCR BK were positive in 33.71% and 57.14% of cases respectively. Computed tomography was the most requested and performed diagnostic imaging (92.86%). The associated tuberculous targets (11.2%) were visceral (78.70%), in particular pulmonary (75.67%). The mean duration of anti-tuberculosis treatment was 12.42 months with a cure of 97.14% of patients. Diagnostic delay (P = 0.01), gibbosity (P = 0.009), and presence of soft tissue abscesses (P = 0.004) were significantly associated with neurological compressions.

CONCLUSION

Pott's disease is common in Abidjan and affects young adults. It manifests as a spinal syndrome with tuberculous impregnation signs. Computed tomography was the most performed diagnostic imaging. The factors associated with neurological compressions are: diagnostic delay, gibbosity and soft tissue abscesses.

Conclusion

A Case Report of a Tragic Story of Pott's paraplegia Cured after Four Years

Pott's disease is a form of spondylodiscitis caused by mycobacterium tuberculosis. It is a serious form of spinal infections that can lead to terrible disabilities in case of undiagnosed and treated early. To document a case of Pott's paraplegia cured after four years. This report details the case of a patient with an undiagnosed case of spinal tuberculosis in a 55-year-old man who had complained of lower back pain and tenderness over the course of several months. The case progressed to the point that he had difficulty standing and numbness, then weakness, of the lower limbs. This patient was only treated with analgesics and antibiotics. Herbal remedies, massage and amulets also played a major role in his treatment. The patient remained bed-bound and paraplegic for four years, after which, he was referred for a thoracolumbar Magnetic Resonance Imaging (MRI) and was diagnosed with tuberculous spondylodiscitis. The patient underwent decompression surgery and started anti-tuberculous drugs. He regained his ability to walk. His lifestyle has improved and he has been living independently for eight years. In conclusion, diagnosis and correct treatment can result in a patient who was previously handicapped becoming independent once again. Medical imaging using MRI can play an essential role in the diagnosis of spinal lesions, including those present in cases of Pott's disease.

[Tuberculous Spondylitis - Diagnosis and Management]

Tuberculous Spondylitis - Diagnosis and Management Abstract. Despite a decreasing incidence of tuberculosis (TB) over the last decades in Switzerland, the frequency of newly diagnosed tuberculous spondylitis has remained stable. It occurs most frequently in old, immunocompromised persons and/or persons who have moved to Switzerland from TB endemic areas. It is a chronic manifestation of TB, which is characterized by 'cold abscesses', neurological deficits and kyphotic spinal deformity. Tuberculous spondylitis is often diagnosed with a delay, which can lead to higher morbidity and treatment complexity. Antibiotic therapy is essential in tuberculous spondylitis. Surgical interventions aim to obtain samples, decompress nervous structures, obtain pain control and, if necessary, deformity correction/stabilization. This paper provides an overview of the modern diagnostic and therapeutic management of tuberculous spondylitis in Switzerland.

Tuberculous retropharyngeal abscess with Pott disease and tuberculous abscess of the chest wall: A case report

RATIONALE

Tuberculous retropharyngeal abscess is rare, but it can be fatal if not treated appropriately. It usually occurs secondary to tuberculosis of the cervical spine. Moreover, tuberculous abscess involving the chest wall is relatively rare in skeletal tuberculosis. Although the optimal treatment is controversial, most clinicians suggest a combination of sufficient antituberculous medication and complete resection to prevent recurrence and increase therapeutic efficacy. Herein, we present an unusual case of retropharyngeal abscess with cervical Pott disease and tuberculous abscess of the chest wall.

PATIENT CONCERNS

The patient was a 27-year-old Indonesian woman who had neck pain, dysphagia, and odynophagia, but no neurological deficit. Examination of the oral cavity showed anterior displacement of the posterior pharyngeal wall. The mass over the right anterior chest wall measured approximately 5 × 4 cm in size.

DIAGNOSES

Radiography and computed tomography findings were suggestive of retropharyngeal abscess extending to the cervical spine and chest wall abscess.

INTERVENTIONS

She was admitted to the hospital for treatment. Drainage of the retropharyngeal and chest wall abscesses with debridement of the chest wall was performed.

OUTCOMES

No complications occurred after early surgical treatment and administration of antituberculous medication. The patient recovered well and went back to her own country after discharge.

LESSONS

Tuberculous retropharyngeal abscess with Pott disease and tuberculous abscess of the chest wall are both complicated diagnoses that physicians have to consider in similar patient presentations.

Therapeutic effect of minimally invasive catheter drainage and local chemotherapy for the lumbosacral tuberculosis without neural symptoms

Increasing number of studies have shown growing incidence of lumbosacral tuberculosis and its complications. However, the treatment options for this disorder are still limited.To evaluate the long-term therapeutic effect and prognosis of minimally invasive puncture catheter drainage and Isoniazid local chemotherapy for the treatment of lumbosacral tuberculosis without neural symptoms under the guidance of computed tomography (CT).A total of 45 patients with asymptomatic lumbosacral tuberculosis were treated by minimally invasive catheter drainage under CT guidance. Forty-two cases had been followed up, which included 22 women and 20 men with an average age of 36.45 years old. Isoniazid was injected locally and antituberculotic drugs were administered for postoperative treatment. Oswestry Disability Index (ODI), visual analogue scale (VAS) evaluation and Cobb angle were recorded before and after operation.Forty-two patients had been followed up and the follow-up term was from 1.2 to 8.5 years (average 60 months). All patients were healed without recurrent cases. The ODI were improved from 14.86 ± 2.02 before operation to 1.48 ± 1.55 after operation. The post-operative (4.19 ± 1.17) VAS score was improved compared to the pre-operative VAS score (0.55 ± 0.55). The post-operative Cobb angle (6.19° ± 3.85°) was also improved relatively to the preoperative Cobb angle (5.90° ± 3.71°).Minimally invasive puncture catheter drainage combined with Isoniazid local chemotherapy is an effective method for lumbosacral tuberculosis without neural symptom. Meanwhile, it can be applied for the treatment of spinal tuberculosis before open surgery.

Tuberculosis of the cervical spine

Tuberculosis of the cervical spine is a rare extra-pulmonary localization. We reported the case of a 59-year-old woman with no medical history. She consulted for a 9 weeks history of painful cervical stiffness. Neurological examination was normal. Plain radiography revealed an osteolytic lesion of the C3 body, with infiltration of adjacent soft tissues. MRI showed a compression fracture of the C3 body with a signal anomaly extending to the anterior epidural space and pre-vertebral soft tissues. First, tumoral extension assessment was done and was normal. BK's research into sputum was negative. Histological examination of a CT biopsy revealed typical granulomatous inflammation. The diagnosis of tuberculosis was retained and antituberculous treatment was started with immobilization for 12 months. The patient had a total functional recovery at 18 months follow-up, with complete radiographic bone reconstruction of C3 after 12 months.

Posterolateral decompression, bone graft fusion, posterior instrumentation, and local continuous chemotherapy in the surgical treatment of thoracic spinal tuberculosis

To investigate the clinical efficacy of surgical treatment for thoracic spinal tuberculosis with kyphosis deformity via posterolateral debridement, fusion, posterior instrumentation and local continuous chemotherapy. A total of 25 patients with thoracic tuberculosis received surgery by posterolateral decompression, fusion, posterior instrumentation, and postural drainage with local continuous chemotherapy between June 2009 and October 2011. The clinical outcomes was evaluated using statistical analysis about deformity correction, bone fusion, neurologic status, and the visual analog score (VAS) and erythrocyte sedimentation rate (ESR). All of 25 patients were followed up for 39.0 ± 10.7 months (range, 24-60 months) postoperatively. There was no recurrence of tuberculosis, breakage and looseness of internal fixation. Bony fusion was achieved in all cases with 6.7 ± 1.9 months. The values of ESR recovered to normal within 6 months postoperatively. All patients with neurological deficit had significant improvement at the final follow-up. The average preoperative Cobb angles were significantly decreased to 12.2 ± 2.9° (range, 8-17°) postoperatively, and at final follow-up were 12.9 ± 2.7°. Our results showed that single-stage posterolateral debridement fusion, posterior instrumentation and local continuous chemotherapy can be expected to yield satisfactory clinical and radiographic outcomes in patients with thoracic spinal tuberculosis.

Bilateral costotransverse and local continuous chemotherapy approach for debridement, fixation, and fusion of contiguous multisegmental thoracic spinal tuberculosis: A retrospective study

The study aims to evaluate the clinical efficacy of bilateral costotransverse debridement, transpedicular fixation, fusion, and local continuous chemotherapy in 20 patients of contiguous multisegmental thoracic spinal tuberculosis (CMTSTB). We analyzed 20 patients with contiguous thoracic spinal tuberculosis (TB) who underwent surgery via bilateral costotransverse debridement, fusion, posterior instrumentation, and postural drainage with local continuous chemotherapy. The clinical outcomes were evaluated in terms of kyphotic angle, bone fusion, neurologic status, erythrocyte sedimentation rate (ESR), and intraoperative and postoperative complications. All of the patients (8M/12F), averaged 45.8 ± 15.6 years old. The mean duration of postoperative follow-up was 30.7 ± 4.0 months. There was no recurrent TB infection. The values of ESR returned to normal levels at final follow-up. All patients got bony fusion within 8.1 ± 2.3 months after surgery. The average preoperative Cobb angle was 39.9° ± 8.6°, correcting to 9.8° ± 2.3° postoperatively and 10.8° ± 2.3° at the last follow-up. All patients with neurological deficit had dramatic improvement at the final follow-up. Our results showed that bilateral costotransverse surgery and local continuous chemotherapy are feasible and effective procedures in the treatment of CMTSTB. The approach can provide radical debridement, rebuild spinal stability, and cure TB.

Could an increase in vigilance for spinal tuberculosis at primary health care level, enable earlier diagnosis at district level in a tuberculosis endemic country?

BACKGROUND

Expert clinicians and researchers in the field of spinal tuberculosis (STB) advocate for early identification and diagnosis as a key to reducing disability, severity of disease, expensive surgery and death, especially in tuberculosis (TB) endemic countries like South Africa. South Africa has the highest incidence per capita of tuberculosis in the world, and a conservative estimate of the incidence of STB in South Africa is 8-16:100 000. People living with STB may initially present to primary health care (PHC) centres, where the opportunity exists for early identification. Spinal pain is the most common presentation of STB, but even this symptom may not be present. Occasionally the only symptoms are neurological injury, dysphagia or referred pain. Computerised tomography-guided biopsy remains the diagnostic gold standard for STB.

AIM

A narrative review was undertaken to investigate the evidence available that could assist with the early diagnosis of STB.

METHOD

Articles were searched for and retrieved from three databases and assessed for quality and relevance to primary settings in a TB endemic country.

RESULTS

The following evidence-based, affordable and available tools could facilitate early diagnosis of STB at PHC and district hospital levels: (1) back pain screening questions, undressed spinal physical examination, HIV and antiretroviral therapy history, (2) erythrocyte sedimentation rate, C-reactive protein, platelets, haemoglobin, white cell count (WCC), sputum for GeneXpert and accurate weight measurement, (3) physiotherapy and/or medical and/or speech therapy assessment, (4) full spinal radiograph, chest radiograph, abdominal ultrasound, urine lipoarabinomannan (LAM) if CD4 < 200 and ultrasound-guided biopsy of superficial abscesses, (5) clear referral guidelines at all levels, (6) a positive response to treatment to confirm the diagnosis.

CONCLUSION

These affordable and simple actions at PHC and district levels could facilitate earlier diagnosis of STB.

Features of 921 Patients With Spinal Tuberculosis: A 16-Year Investigation of a General Hospital in Southwest China

Southwest China has a high burden of spinal tuberculosis (TB). Few large case studies of spinal TB in southwest China have been conducted. This study investigated the features of 921 patients who were treated for spinal TB at a general hospital in southwest China between 2001 and 2016. Demographic data, clinical data, laboratory data, imaging findings, treatment methods, and outcomes of patients who were admitted to the hospital for spinal TB were reviewed retrospectively. The annual incidence of spinal TB increased throughout the study period. The greatest number of patients were 41 to 50 years old (22.04%). Local pain was the most common symptom (97.8%). A significant difference in the duration of symptoms was observed between rural populations (28.40 months) and urban populations (10.17 months) (P=.041). Of the patients, 32.68% had a normal erythrocyte sedimentation rate and 25.84% had a normal C-reactive protein level. The lumbar spine was the most commonly involved spinal site (44.77%), followed by the thoracic spine (43.60%). All of the patients underwent chemotherapy, and 77.10% of patients underwent surgery. Most of the patients were cured, with the exception of 2.19% of patients who discontinued chemotherapy after early improvement of clinical status. Spinal TB is still a major public health problem in southwest China. Chemotherapy and surgery can yield satisfactory outcomes with timely diagnosis and long-term treatment. It is urgent to increase the attention paid to spinal TB and improve knowledge of this disease among the general public, especially in southwest China. [Orthopedics. 2017; 40(6):e1017-e1023.].

Atypical spinal tuberculosis involved noncontiguous multiple segments: Case series report with literature review

In its typical form, spinal tuberculosis (TB) presents as destroyed contiguous vertebral bodies with involvement of intervertebral discs and paravertebral or psoas abscesses. Atypical forms are uncommonly reported. Here, we describe 8 patients with noncontiguous multisegmental spinal TB with no intervertebral disc involvement. From 2013 to 2014, we surgically treated 384 patients with spinal TB to relieve spinal cord compression, re-establish spinal stability, confirm the diagnosis, and debride the TB foci. Eight of these patients had noncontiguous multisegmental TB without intervertebral disc involvement. Seven of the 8 patients underwent short-segmental fixation and fusion at a single focus. Appropriate combinations of anti-TB medication were continued until final follow-up. They were followed at established intervals using plain radiography, 3-dimensional computed tomography, and magnetic resonance imaging of the surgical region to evaluate fusion and the condition of the foci. Mean follow-up was 26.6 months (range, 24-32 months), during which time all patients were prescribed the appropriate anti-TB medications. Satisfactory clinical and radiological results were obtained in all patients, without complications. Presentation of noncontiguous multisegmental spinal TB without the involvement of intervertebral disc resembles that of a neoplasm or other spinal infection. Differentiation requires the presence of a combination of general symptoms, laboratory test results, appropriate radiological results, and the physician's experience. For patients in whom surgery is indicated, the patient's general condition should be taken into consideration. Surgical intervention only focus on the responsible level is less invasive and can achieve satisfactory clinical and radiographic outcomes.

[Spinal tuberculosis: experience in a third level medical facility in Puebla, Mexico]

BACKGROUND

Pott's disease or spinal tuberculosis (STB) is a serious infectious disease, caused by the migration of the bacterium Mycobacterium tuberculosis to the spine. Knowing this disease is a priority for all the physicians. The objective was to show the experience in patients with STB treated in a third level hospital in Puebla, Mexico.

METHODS

Descriptive study. From January to December, 2014, we collected information of patients with STB. The variables were age, gender, length of hospital stay, affected segment of the spine, associated diseases, symptoms, diagnostic methods, type of treatment and complication. We used descriptive statistics, as well as measures of central tendency and dispersion.

RESULTS

We studied 14 patients, 71.4 % male; mean age was 60.29 ± 16.54 years (33-93); the average hospital stay was 18.93 ± 9.32 days (4-34). The affected segment was thoracic in six patients (42.85%) and lumbar in eight (57.15%). Nine patients had associated diseases (64.28%) and five did not (35.7%). All patients received medical treatment and 11 surgical procedures were performed in a total of five patients (35.7%). Complications occurred in two patients (14.3%).

CONCLUSIONS

STB must be managed early to avoid complications. Coordination with the first level of medical care is very important, as well as the adherence to national and international guidelines.

Concomitant metastatic cutaneous tuberculous abscesses and Pott disease in an immunocompetent patient

Tuberculosis affects one-third of the world's population. The incidence of extrapulmonary tuberculosis including cutaneous and skeletal manifestations has increased in the last decades. The authors report a clinical case of concomitant metastatic cutaneous abscesses and Pott disease in an immunocompetent patient, a rare presentation of tuberculosis.

Immunotherapy for non-responders among patients of spinal tuberculosis

BACKGROUND

Combined chemo- and immunotherapy are the major advancement in the treatment of tuberculosis. Immunotherapy supposedly increases cure rate while reducing the duration of treatment and tissue damage. Non-responders are those patients of tuberculosis who do not respond to anti-tubercular therapy (ATT) in the desired manner despite the mycobacteria showing sensitivity to the given drugs. The role of immunotherapy in the treatment of this particular subset of patients has been investigated scarcely.

METHODS

The present study included a retrospective review of prospectively collected clinico-radiological data of 14 non-responder patients who were taking ATT for spinal tuberculosis for a mean duration of 10.3 months. An immunotherapeutic regime comprising of single intramuscular injection of vitamin D 600,000IU, 3 days course of oral albendazole 200mg daily, salmonella vaccine 0.5ml intramuscular and influenza vaccine 0.5ml intramuscular were added to ATT. The vaccines and the course of oral albendazole were repeated after a month.

RESULTS

Before immunotherapy, seven patients were partially dependent while other seven were completely dependent on others for activities of daily living. All except one patient after treatment became independent till last follow-up (p value <0.01). Post immunotherapy, ATT was continued for mean duration of 4.9 months with mean follow-up of 22.4 months. All patients showed good clinical response within 2-6 weeks after the initiation of immunotherapy.

CONCLUSIONS

The crux to success of the immunotherapy regime is its potential to restore the existing Th1 Th2 imbalance and to provide substitute to the anergic and dysfunctional immune cells.

The efficacy of local continuous chemotherapy and postural drainage in combination with one-stage posterior surgery for the treatment of lumbar spinal tuberculosis

BACKGROUND

The objective of this study was to compare the outcomes of one-stage posterior surgery involving debridement, bone grafting, and instrumentation with and without local continuous chemotherapy and postural drainage for the treatment of lumbar spinal tuberculosis.

METHODS

From January 2009 to January 2013, 109 patients with lumbar spinal tuberculosis were treated in our center using a posterior surgical approach. Patients underwent one-stage posterior debridement, bone grafting, and instrumentation, without (group A) and with (group B) local continuous chemotherapy and postural drainage. Clinical and radiographic results for the two groups were analyzed and compared. Clinical efficacy was evaluated based on surgery duration and blood loss. The Frankel scale was used to evaluate neurological function. A visual analog scale was used to assess low back pain. Bone graft fusion and instrumentation failure were monitored by radiography, and tuberculosis activity was monitored by erythrocyte sedimentation rate (ESR) and C-reactive protein testing.

RESULTS

Groups A and B contained 52 and 57 patients, respectively. Patients were followed for 18-36 (mean, 26.64 ± 4.2) months. All bone grafts ultimately fused, but the fusion rate was significantly more rapid in group B [6.4 ± 0.5 (range, 5-10) months] than in group A [8.9 ± 0.6 (range, 6-12) months; P < 0.05]. At 6 weeks postoperatively, ESR levels differed significantly between groups A and B (24.6 ± 1.5 vs. 16.3 ± 1.1 mm/h; P < 0.05). ESR levels normalized in both groups at 16 weeks.

CONCLUSIONS

Local continuous chemotherapy and postural drainage effectively eliminated infection foci caused by abscess remnants and accelerated interbody bone fusion in patients with lumbar spinal tuberculosis undergoing one-stage posterior surgery involving debridement, bone grafting, and instrumentation.

Management of spinal tuberculosis - a metropolitan city based survey among orthopaedic and neurosurgeons

OBJECTIVE

To explore the core understanding of spinal tuberculosis and its current management plans by orthopaedics and neurosurgeons.

METHODS

The questionnaire-based study was conducted from July 2011 to November 2012 in Karachi and comprised consultant orthopaedics and neurosurgeons belonging to 4 private and 3 government tertiary care teaching hospitals and having a minimum five years of post-fellowship experience. A pre-designed questionnaire was used to explore the current practice in spinal tuberculosis regarding its clinical presentation, diagnosis and treatment. SPSS 15 was used for statistical analysis.

RESULTS

There were 48 subjects in the study; 24(50%) orthopaedic surgeons and 24(50%) neurosurgeons. According to 44(91.70%) respondents, common age for spinal tuberculosis was second and third decades of life, and 37(77.08%)reported refractory back pain with or without neurological deficits as the commonest clinical finding. Typical magnetic resonance imaging findings was the uniform observation of all the 48(100%) respondents. Diagnosis was made by histopathological findings by 39(81.25%) respondents. Anti-tuberculosis therapy was started empirically on the basis of clinical, laboratory and radiological findings by 33(68.75%) respondents. Those in favour of giving anti-tuberculosis therapy for 18 months were 32(66.7%) respondents, and 33(68.75%) thought surgery does not expedite recovery.

CONCLUSIONS

Extremely variable tools of diagnosis and diversified approaches for the treatment are alarming signs for the possible development of resistant strains and complications of spinal tuberculosis.

[A CASE OF SPINAL TUBERCULOSIS WITH NEUROPATHY AMELIORATED BY DRAINING A TUBERCULOUS ILIOPSOAS ABSCESS WITHOUT SPINAL SURGERY]

A 75-year-old woman was referred to our hospital after a health check-up disclosed abnormal shadows in the bilateral lungs. The patient was admitted to our hospital after being diagnosed with pulmonary tuberculosis. A physical examination showed a mass in the left inguinal area. Enhanced computed tomography revealed that the tuberculosis involved several regions including the lumber vertebrae, iliopsoas muscles, and left inguinal area. A therapeutic regimen consisting of INH, RFP, EB, and PZA was begun. Neuropathy in the lower extremities and dysuria indicated a spinal lesion, and spinal surgery was considered. However, the patient's history indicated that these symptoms were likely due to an iliopsoas abscess rather than a spinal lesion. This hypothesis was confirmed when the patient's symptoms improved with no sequelae after the abscess was drained. Our case demonstrates that spinal lesions as well as iliopsoas abscesses can cause neuropathy, and underscores the importance of obtaining a patient's history to correctly diagnose the disease and determine the appropriate treatment options.

[Treatment of thoracolumbar spinal tuberculosis with single posterior debridement, bone grafting, internal fixation and local chemotherapy]

OBJECTIVE

To evaluate the clinical effects of single posterior debridement, bone grafting, internal fixation and local chemotherapy in treating thoracolumbar spinal tuberculosis.

METHODS

From February 2009 to September 2012,11 patients with thoracolumbar spinal tuberculosis were treated by single posterior debridement, bone grafting, internal fixation and local chemotherapy. There were 7 males and 4 females, aged from 27 to 65 years old with an average of 53.7 years. The courses of disease was from 3 months to 2 years with the mean of 9 months. According to ASIA standard of spinal cord injury, 3 cases were grade C and 8 cases D. After treatment, clinical effects were evaluated by ASIA grade, visual analogue score (VAS) and Oswestry Disability Index (ODI); kyphosis Cobb angle change was observed by X-rays.

RESULTS

Eleven patients were followed up from 12 to 29 months with an average of 18 months. ASIA grade of spinal cord injury, 3 patients with grade C improved to grade D in 2 cases and grade E in 1 case 8 patients with grade D improved to grade E in 7 cases and unchanged in 1 case. VAS decreased from preoperative 6.10 ± 1.30 to 1.70 ± 0.80 at 3 d after operation (P < 0.05). ODI improved from preoperative (68.36 ± 10.41)% to (14.55 ± 8.99)% (P < 0.05) at 3 d after operation. Kyphotic Cobb angle was corrected from preoperative (22.64 ± 4.84)° to (4.27 ± 1.49)° (P < 0.05) on the 3rd day after operation, and angle loss was mild at final follow-up, there was no significant difference between postoperative at 3 d and final follow-up.

CONCLUSION

Single posterior debridement, bone grafting, internal fixation and local chemotherapy for the treatment of thoracolumbar spinal tuberculosis can effectively remove the lesion, improve nerve function and correct deformity, has advantage of single incision, little trauma, and low recurrence rate. But it still need long-term and systemic treatment with anti-TB drugs.

Cervical spinal tuberculosis: a preliminary study of clinical diagnosis and management

BACKGROUND

Cervical involvement in spinal tuberculosis is rare; however delayed diagnosis and treatment may result in massive, irreversible neurological deterioration. The purpose of this study is to report on a strategy for clinical diagnosis and management of cervical spinal tuberculosis.

MATERIAL AND METHOD

Eighteen patients (13 males and 5 females) during 1998-2013 were retrospectively reviewed at Chiang Mai University Hospital. The patients had a mean age of 51.4 years (range 37-68 years). History, examination, radiographs, MRI and tissue sampling were used in diagnosis. Most of the patients were given antituberculous therapy (ATT) and underwent surgical management. The mean follow-up period was 12.8 months.

RESULTS

Axial neckpain, quadriparesis, spastic gait and hand clumsiness were the predominant symptoms. Disc narrowing, endplate destruction andparaspinal soft tissue swelling were the prominent radiographic findings. MRI found Gadolinium enhancement of prevertebral soft tissue, T2 hypersignal of the intervertebral discs, intraosseous T2 hypersignal at the vertebral body, and disc fragmentation. Thirteen patients underwent single-stage anterior debridement with fusion. Three patients underwent posterior fusion alone. Axial neck pain improved in all patients. Nurick's disability index and fusion rate improved in 70% of the patients after conservative and surgical treatment.

CONCLUSION

Cervical spinal tuberculosis should be suspected in endemic patients with severe neck pain and progressive neurological deficit. Histopathology is the gold standard of tuberculosis diagnosis. Anti-tuberculosis drugs should be continued for at least 12 months. Radical anterior debridement and instrumented fusion has demonstrated favorable results. The posterior approach is an alternative treatment in patients when the anterior approach cannot be performed or as part of second-stage surgery.

Fate of kyphosis in tuberculosis of subaxial cervical spine treated non-operatively

OBJECTIVE

Observation of post treatment kyphotic angle in patient of cervical spine tuberculosis managed non operatively.

BACKGROUND

The incidence of tuberculosis of cervical spine is about 6-9%. The most dreaded complications of spinal tuberculosis are neural involvement and spinal deformity. Due to destruction of the vertebra tuberculosis of spine usually leads to variable amount of kyphotic deformity.

METHODS

We retrospectively reviewed 13 patients with clinico-radiological diagnosis of cervical spine tuberculosis managed in our centre between 2004 to 2011. The patients were started on antitubercular therapy. Crutchfield tongs traction was applied 8 to 12 weeks followed by mobilization with four post collar. The kyphotic angles were measured by radiograph at presentation and last available follow up radiograph.

OBSERVATIONS

The mean age of the patients was 20 years. C3-C4 vertebra was the most commonly involved area. One patient had single vertebra involvement, five patients had two vertebrae involvement, five patients had three vertebrae involvement and two patients had four vertebrae involvement. The average number of vertebrae involved was 2.6 vertebrae. 9 out of 13 patients had neural deficit at the time of initial presentation. The mean follow up was 21.23 months (12 to 42 months). All patients responded favorably and had neural recovery. At final follow up, 10 out of 13 patients had improvement in kyphotic angle, two patients had deterioration of kyphotic angle and one patient had no change in kyphotic angle. Only one patient had significant deterioration in kyphotic angle.

CONCLUSIONS

Non operative treatment of cervical spine tuberculosis by initial traction and antitubercular therapy improves the pretreatment deformity irrespective of the number of vertebra involved.

Computed tomography-guided percutaneous focal catheter infusion in the treatment of spinal tuberculosis

The study aimed to investigate the efficacy of computed tomography (CT)-guided percutaneous focal catheter infusion for the treatment of spinal tuberculosis. Clinical and follow-up data from 27 spinal tuberculosis patients who underwent CT-guided intervertebral catheterized infusion chemotherapy from May 2008 to October 2011 were retrospectively analyzed; treatment included pure intervertebral infusion chemotherapy and catheter drainage for continuous abscess washing during infusion chemotherapy. All surgeries were successfully completed under CT guidance without complications. The C-reactive protein levels of most patients rebounded within the first postoperative week but significantly decreased after the second and fourth postoperative weeks. CT-guided percutaneous focal catheter infusion was effective for the treatment of spinal tuberculosis and induced little trauma; this treatment could also relieve the symptoms and improve the quality of life of elderly patients with poor general conditions.

Atypical imaging features of tuberculous spondylitis: case report with literature review

Spinal tuberculosis in its typical form that shows destruction of two adjacent vertebral bodies and opposing end plates, destruction of the intervening intervertebral disc and a paravertebral or psoas abscess, is easily recognized and readily treated. Atypical tuberculous spondylitis without the above mentioned imaging features, although seen infrequently, has been well documented. We present, in this report, a case of atypical tuberculous spondylitis showing involvement of contiguous lower dorsal vertebral bodies and posterior elements with paravertebral and epidural abscess but with preserved intervertebral discs. The patient presented in advanced stage with progressive severe neurological symptoms due to spinal cord compression. Non-enhanced magnetic resonance imaging led to misdiagnosis of the lesion as a neoplastic process. It was followed by contrast enhanced computed tomography of the chest and abdomen that raised the possibility of an infectious process and, post-operatively, histopathological examination of the operative specimen confirmed tuberculosis. This case indicates the difficulty in differentiating atypical spinal tuberculosis from other diseases causing spinal cord compression. The different forms of atypical tuberculous spondylitis reported in the literature are reviewed. The role of the radiologist in tuberculous spondylitis is not only to recognize the imaging characteristics of the disease by best imaging modality, which is contrast enhanced magnetic resonance imaging, but also to be alert to the more atypical presentations to ensure early diagnosis and prompt treatment to prevent complications. However, when neither clinical examination nor magnetic resonance imaging findings are reliable in differentiating spinal infection from one another and from neoplasm, adequate biopsy, either imaging guided or surgical biopsy is essential for early diagnosis.

[Pott's disease (about 16 cases)]

INTRODUCTION

Pott's disease or spinal tuberculosis is rare, but represents the most common form of osteo-articular tuberculosis in endemic countries.

MATERIAL AND METHODS

[corrected] From January 2000 to December 2010, we collected 16 cases of Pott's disease. We analyzed clinical and radiological profile, means of confirmation and treatment.

RESULTS

Spinal and chest pain were the most frequent signs. Four patients had neurological signs. The diagnosis was made by the detection of bacillus in the pus of paravertebral abscess in six cases, by histological study of vertebral biopsy in five cases, biopsy of another associated lesion in one case and in front of radio-clinical arguments with good clinical evolution under antibacillary treatment in four cases. The antibacillary treatment associating four drugs was indicated and correctly followed by all patients. Surgical drainage was associated in five cases. The evolution was good in all cases.

DISCUSSION

Diagnosis of Pott's disease is late when there is no neurological sign. Imaging allows to make early diagnosis with MRI. Prognosis is good when treatment is started early.

Microbiological and immunological diagnosis of tuberculous spondylodiscitis

BACKGROUND

Tuberculous spondylodiscitis is one the many manifestations of active tuberculosis (TB) and can result following primary infection or, more frequently, from reactivation of active TB in subjects with latent TB. Definitive diagnosis of tuberculous spondylodiscitis requires the identification of Mycobacterium tuberculosis in the biological sample following microbiological analysis.

AIM

To summarize the recent advancement in the diagnosis of TB, focusing on classical and molecular microbiological procedures, providing an overview on the recent advancements in the understanding of TB pathogenesis and their implications for the immunological diagnosis

MATERIALS AND METHODS

Isolation in culture of the bacilli and detection using molecular tools are the gold standards, though sensitivity of these assays is significantly lower compared to what observed for pulmonary TB, making diagnosis of spinal TB challenging.

RESULTS

The use of the interferon-gamma release assays (IGRAs) for the immunological diagnosis of TB infection could be of help and shall precede the invasive techniques, such as biopsy or surgery, required to obtain the biological sample. IGRAs measure the presence of effector T cells in the blood that can readily respond to an antigenic stimuli by secreting cytokines, and that are an indication of the presence of the bacilli in vivo. IGRAs are more sensitive and specific than the intradermic reaction of Mantoux, though both these immunological tests cannot distinguish between latent TB infection and active TB.

CONCLUSIONS

A modern diagnosis of TB spondylodiscitis should rely on the use of microbiological and immunological assays and the latter could potentially be of great help in monitoring therapy effectiveness.

Tuberculous spondylodiscitis: epidemiology, clinical features, treatment, and outcome

BACKGROUND

Tuberculous spondylodiscitis (TS) is a rare but serious clinical condition which may lead to severe deformity and early or late neurological complications.

AIM

To discuss certain aspects of the approach to TSs, focusing upon epidemiology, diagnosis, and treatment outcome.

MATERIALS AND METHODS

For the purpose of this review, a literature search was performed using the Pubmed database through to 19th October 2011 to identify studies published in the last 20 years, concerned in epidemiological, clinical, diagnostic, and therapeutical aspects of TS in adults. Only studies drafted in English language and reporting case series of more than 20 patients have been included.

RESULTS

TS has been reported to accounts for 1-5% of all TB cases, and for about 50% of the cases of articulo-skeletal TB infections. Despite the actual availability of more effective diagnostic tools, early recognition of TS remains difficult and a high index of suspicion is needed due to the chronic nature of the disease and its insidious and variable clinical presentation. A prompt diagnosis is required to improve long term outcome, and a microbiological confirmation is recommended to enable appropriate choice of anti-mycobacterial agents. Surgery has an important role in alleviating pain, correcting deformities and neurological impairment, and restoring function.

CONCLUSIONS

Further studies are required to assess the appropriate duration of anti-microbial treatment, also in regarding of a combined surgical approach.

Presentation of a rare sacral tuberculosis in an otherwise healthy patient: diagnostic challenge and review of treatment

In the developed world, spinal tuberculosis is a rare and often overlooked cause of a spinal mass. The most common sites for vertebral tuberculosis are the lower thoracic and upper lumbar spine, while the cervical and sacral (<5%) areas are rarely infected. Magnetic Resonance Imaging has proven to be the best imaging modality to identify spinal TB while antibiotic treatment has made spinal tuberculosis a diagnostic problem instead of a therapeutic one. We present the case of a 30-year-old male who presented with the sole complaint of a two-month history of radiating lower back pain. Imaging findings included normal radiographs and a large, heterogeneously T2-enhancing lesion found to be tuberculosis. Treatment included CT-aspiration and chemotherapy. TB spondylitis is primarily treated with medical management, and surgical intervention is usually warranted only when there is an unacceptable degree of kyphosis or persistent neurological symptoms.

Tuberculosis of the spine. A systematic review of case series

PURPOSE

The objective of this systematic review was to characterise the methodological issues, as well as clinical, diagnosis, microbiological and treatment characteristics of patients with spinal tuberculosis.

METHODS

We conducted a systematic review including prospective or retrospective case series written in English, Spanish, French, German and Italian published in the period from January 1980 to March 2011.

RESULTS

Thirty-seven articles were included with a total of 1,997 patients; the median of the percentage of men was 53% (interquartile range [IQR] 48-64) and the median of the patients mean age was 43.4 (IQR 37-55). The most common symptom reported was back pain, and thoracic spine was the most frequent segment involved. Spinal plain radiography was done in 35 studies (94.6%), magnetic resonance imaging (MRI) in 26 (70.2%), computed tomography scan (CT-scan) in 13 (35%) and microbiological diagnosis in 29 (78.3%). Surgical treatment was reported in 28 articles 75.7%; finally, 24 articles reported follow-up, and in 15 of them at least 80% of patients improved.

CONCLUSIONS

Spinal TB is still an important public health issue, it must be suspected in the presence of back pain or characteristic images and should be confirmed with microbiological procedures. Chemotherapy treatment is often used; in contrast, there is heterogeneity in the percentage of patients treated by surgery.

Surgical treatment of spondylodiscitis. An update

CONCEPT

Spondylodiscitis refers to an infection affecting the intervertebral disk, the vertebral body or the posterior arch of the vertebra being aetiologically, pyogenic, granulomatous (tuberculosis, brucellosis, or fungal infection) or parasitic.

DIAGNOSIS

Spondylodiscitis diagnosis is based on clinical symptoms, a combination of erythrocyte sedimentation rate with C-reactive protein (CRP) tests and, less useful, leukocytosis. Blood culture is also a very cost-effective method of identifying organisms. Plain radiographs are useful, however changes may take several months to appear. Radionuclide tests are currently less used; nevertheless, fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) shows encouraging results particularly when magnetic resonance images (MRI) are unconvincing in the distinction between degenerative changes and infection. MRI with gadolinium enhancement is the choice for image diagnosis.

MANAGEMENT

Medical management is usually the basis for treatment, alone or in combination with surgery. Surgical approach, either by endoscopy or open, is indicated for biopsy when clinical evolution is unsatisfactory and no micro-organism has been isolated, and also whenever a root, spinal cord or dural compression is seen on MRI; spinal instability or severe deformity are also clear indications for surgical treatment. Less invasive surgery either CT-scan guided or, particularly, by endoscopy has good results. However open surgery is still the standard. The anterior approach allows for anterior disc and bone debridement. The posterior approach is indicated when posterior elements are involved or in the presence of an epidural abscess. Although good results have been claimed, the use of instrumentation in the presence of an infected focus is controversial, as the use of cages or BMPs are.

Prompt restoration of airway along with rapid neurological recovery following ultrasonography-guided needle aspiration of a tubercular retropharyngeal abscess causing airway obstruction

Upper respiratory obstruction in cervical spine tuberculosis rarely occurs due to retropharyngeal cold abscess or secondarily from its rupture. Options for securing the airway are intubation, tracheostomy and needle aspiration or surgical drainage. A young boy presented with neck pain, quadriparesis and stridor, suggesting subacute airway obstruction in advanced tubercular spondylodiscitis of cervical spine C3-C4 (cervical 3rd and 4th level) with extradural compressive myelopathy (C3-C5) and a large retropharyngeal cold abscess. An urgent ultrasonography-guided needle aspiration with a head low position through the left posterior triangle was performed with adequate precautions and back-up for advanced airway management. Needle aspiration yielded 200 ml of pus. Stridor and hoarseness of voice decreased immediately. Within two-and-a-half hours, the patient improved neurologically. Although guided needle aspiration is one of the treatment options, there is a strong tendency to undermine this technique in favour of other options, especially surgery.

Primary disseminated MDR-TB in a Bangladeshi man: a silent and emerging clinical problem for clinicians

A 26 years old Bangladeshi man experienced sudden gross haematuria for 10 days when he was working in Italy in June'07 that was resolved spontaneously. Six months' later he again developed haematuria and was admitted into an Italian hospital for its evaluation and management. In the mean time, he developed low grade fever, cough, back pain, spinal angulations, walking difficulty. His X-ray chest postero-anterior view revealed cavitary lesions in upper zones of both lung fields. Intravenous Urography (IVU) was done which revealed hydronephrosis and hydroureter of left kidney. Magnetic Resonance Imaging (MRI) of dorso-lumber spine revealed collapse of D10-12 and L4-5 vertebral bodies with perivertebral and epidural abscess. Sputum and urine smear for Acid-Fast-Bacilli (AFB) demonstrated the organisms on Z-N stain and AFB culture and sensitivity demonstrated that it was resistant to isoniazide, Rifampicin and streptomycin and diagnosed as primary disseminated multi-drug Resistant tuberculosis (MDR-TB). Second-line drugs were started in Italy on 15th January'08 and were continued thereafter in National Institute of Diseases of the Chest and Hospital (NIDCH). A ureteric stent which was given in Italy to get relief of hydro-ureter was removed in Dhaka. A neurosurgery (costo-transversectomy with decompression of spine) was done in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka and patient get relief of back pain paresthesia. Lastly, his sputum and urine AFB smear and AFB culture became negative. So, primary disseminated MDR-TB with renal, spinal and pulmonary involvement was diagnosed in this Bangladeshi man who had a sputum AFB culture and sensitivity during his initial diagnostic work-up in Italy. It's an alarming case that demonstrated necessity of sputum AFB culture and sensitivity during initial diagnostic work-up.

[Pott's disease: report of 82 cases]

Nous rapportant dans cette étude, les résultats de l'expérience du service de neurochirurgie du CHU Hassan II de Fès dans la prise en charge du mal de pott dans la région de Fès. Il s'agit d'une étude rétrospective de quatre-vingt-deux cas; étalée sur une période de cinq ans (janvier 2002 au décembre 2006). L'objectif de ce travail était d'illustrer les différents aspects épidémiologiques, diagnostiques et thérapeutiques de la localisation vertébrale de la tuberculose dans notre pratique. L'âge moyen de nos patients était de 43,1 ans, avec une légère prédominance féminine (53,82%). La durée d'évolution de la maladie était longue (dix mois en moyenne); ceci est expliquée par la symptomatologie initiale insidieuse faite de rachialgies (98,78%) et une admission des patients au stade de complications neurologiques (41,46%). La radiographie standard était réalisée chez tous nos patients, et complétée par la TDM dans 86.58% des cas ce qui a permis de déceler la prédominance de l'atteinte dorsale et lombaire. L'IRM est l'examen de choix, elle était demandée chez tous les malades déficitaires (37,8%).Tous nos patients ont bénéficié d'un traitement antibacillaire associé à une immobilisation du foyer pottique. Une décompression par voie antérieure était réalisée chez 29 patients (35,36%); alors que la laminectomie n'était pratiquée que chez 5 patients (6.09%), tandis que l'évacuation de l'abcès de psoas était réalisée chez 25 patients (30,48%). Le diagnostic de certitude histologique était posé dans 51 cas (62,19%). Les meilleurs résultats étaient obtenus chez les malades opérés par voie antérieure, 26 cas (89,65%) de récupération totale et 3 cas (10,34%) partielle. L'évolution vers la consolidation et la fusion vertébrale était la règle chez tous nos malades et ceci au bout de 4 à 18 mois après le traitement.

[Pott's disease of the upper cervical spine (three cases and literature review)]

BACKGROUND

Sub-occipital Pott's disease is rare, but dangerous.

AIM

To recall diagnostic aspects and spatially the neuroradiological ones of sub-occipital Pott's disease.

METHODS

We describe three patients with sub-occipital Pott's disease followed in our department from 2002 to 2007.

RESULTS

There were two women and one man (mean age at onset: 48 years). The early clinical picture was non specific. Exploration, in addition to standard radiographies included a computerized Tomography (CT) (n=2) and MRI (n=1 and n=3). The diagnosis was confirmed histologically on a biopsy of the abscess (n=1), a bacteriological evidence (n=2) and retained thanks to argument presumption (n=3). The treatment was based on quadruple antituberculous chemotherapy with external traction (n=2 and n=3) associated with urgent surgery (n=1) because of the worsening of the neurological complications. The evolution was fatal (n=1) and positive (n=2 and n=3).

CONCLUSION

Tuberculosis should be suspected in patients with chronic torticollis and residing in an area when tuberculosis is endemic. Medical treatment is based on a quadruple antituberculosis chemotherapy with traction in the presence of atlanto-axial instability. Surgery is reserved in case of neurological worsening or persistent instability.

Tuberculous retropharyngeal abscess associated with spinal tuberculosis well controlled by fine-needle aspiration and anti-tuberculous chemotherapy

We present a rare case of a tuberculous retropharyngeal abscess (RPA) associated with spinal tuberculosis (TB) (Pott's disease). A patient presented with RPA and collapse of the second cervical vertebra. Fine needle aspiration was performed through the pharynx, not only for diagnosis but also for reduction of the abscess. Tuberculous RPA was diagnosed by microbiological tests of the aspirated fluid from the abscess, which was likely to be extended from Pott's disease. Anti-TB chemotherapy after the aspiration proved effective, resulting in the resolution of the abscess. Early diagnosis and treatment are essential in order to prevent life-threatening complications.

Tuberculosis of the Subaxial cervical spine: a case series from Tema, Ghana

BACKGROUND

Tuberculosis (TB) is endemic in West Africa. However, TB of the cervical spine is rare.

OBJECTIVE

To report a series of patients with TB of the sub-axial cervical spine (SACS), in order to illustrate its presentation, treatment and outcome.

METHODS

The patients were studied with respect to clinical history and physical examination. Laboratory tests, plain cervical spine X ray studies and myelography with post-myelographic CT scans were used for diagnosis. All patients underwent surgery and antituberculous therapy (ATT). Histopathologic results of surgical specimens were also analysed.

RESULTS

All the patients were male and presented with severe neck pain and long tract signs. Osteomyelitis of the SACS was evident with disc space involvement and prevertebral soft tissue swelling. None of the patients had a history of pulmonary TB or TB meningitis; none had a positive Mantoux test. All patients improved neurologically after surgery and ATT.

CONCLUSION

Although tuberculosis of the cervical spine is rare, the possibility of the disease should be considered when patients from areas in which the disease is endemic report with severe neck pain. Surgery could be indicated in cases with associated neurologic deficit and or spinal column instability. Anti-tuberculosis therapy should be continued for at least six months.

[Combination of intensified anti-tuberculosis with operation for treatment of thoracolumbar tuberculosis]

OBJECTIVE

To evaluate the clinical significance of the combination of intensified anti-tuberculosis treatment, posterior transpedicular screw system internal fixation, intertransverse bone grafting, and anterior approach focus debridement for the treatment of thoracolumbar tuberculosis.

METHODS

From January 2005 to December 2007, 20 patients with thoracolumbar tuberculosis (T10-L3) were treated. There were 13 males and 7 females aged 21-64 years old (average 44 years old). The course of disease was 3 months to 3 years (average 10 months). The focus involved single vertebrae bodies in 8 cases, two vertebrae bodies in 9 cases, and three vertebrae bodies in 3 cases. The preoperative Cobb angle was 9-35 degrees (average 26.7 degrees). The neurological function was evaluated according to the Frankel grading criterion, there were 2 cases of grade B, 5 of grade C, 7 of grade D, and 6 of grade E. Vertebral body defect index score: 9 cases of 1-2 points, 7 cases of 2-3 points, and 4 cases above 3 points. After receiving the systemic five-drug treatment of anti-tuberculosis for 2-3 weeks, the patients underwent the posterior transpedicular screw system internal fixation and intertransverse bone grafting, and then received tuberculosis focus debridement via anterior approach, nerve decompression, and bone grafting fusion.

RESULTS

The time of operation averaged 210 minutes and the mean blood loss during operation was 650 mL. Postoperatively, 2 patients had mild belting sensation in their thorax and 2 patients had mild pneumothorax. Their symptoms relieved 2-3 weeks later without specific treatment. All the patients were followed up for 12-23 months. X-ray films showed that all the patients achieved successful bony fusion 6-18 months after operation, and the Cobb angle was 7-21 degrees (average 15.2 degrees) 12 months after operation without aggravation. The Frankel grading system was used to assess the postoperative neurological function, 1 patient in grade B before operation was improved to grade C after operation, 1 patient in grade B was improved to grade D, 1 patient in grade C was improved to grade D, 4 patients in grade B were improved to grade E, and 7 patients in grade D were improved to grade E. All of the incisions healed and erythrocyte sedimentation rate became normal 2 weeks to 3 months after operation. All the patients showed no obvious abnormity in liver and kidney function. There was no recurrence of tuberculosis.

CONCLUSION

It seems that the systemic drug treatment of anti-tuberculosis before and after operation, the thorough debridement of focus during operation, and the effective and reliable way to reconstruct for the spinal stability are the key points for the treatment of spinal tuberculosis.

Giant retropharyngeal abscess secondary to tubercular spondylitis

Chronic retropharyngeal abscess secondary to tubercular spondilitis is a rare phenomenon. Anatomical location of this abscess makes it a life threatening condition requiring prompt diagnosis and treatment thus preventing morbidity and mortality. Authors are documenting a case of tubercular spondylitis of cervical region in a 12-year old male child with huge retropharyngeal abscess extending to superior mediastinum. Clinically, patient had respiratory distress but no neurological deficit. USG (Ultrasonography) guided aspirate of abscess sent for microscopy and culture showed acid fast bacilli. Multiple USG guided aspirations under antibiotic and antitubercular cover (Category I) were done. Patient is doing well at three month follow-up.

Tubercular epidural abscess in children: report of two cases

Tubercular spinal epidural abscess (SEA) is an uncommon infectious occurrence. SEA was first described in 1761. Clinical prospects of tubercular SEA are graver, if not promptly diagnosed and treated appropriately. We present two cases of spinal epidural abscess of tubercular etiology who progressed to paraplegia over the course of disease. MRI pointed towards an epidural abscess in the dorsal spine. Histopathological analysis revealed SEA, tubercular in nature in both cases. Patients responded to surgical decompression and anti-tubercular therapy (ATT). Such type of clinical entities has least been documented.

Epidural tuberculosis involving the entire spine

We discuss an elderly male who developed severe back pain, rapidly progressing paraparesis and urinary retention consequent to L5-S1 spinal tuberculosis with dissemination of epidural tubercular abscess and granulation tissue to the cervical, thoracic, lumbar and sacral region. The initial diagnosis of lumbo-sacral pathology with high thoracic extension was tackled by an L5 laminectomy and decompression along with saline flushing and evacuation of the thoraco-lumbar and sacral epidural abscess with the aid of a catheter passed superiorly and inferiorly. He developed neck pain and upper limb weakness subsequently and was found to have extensive extradural cervical compression by granulation tissue. He underwent C4-7 laminectomy and decompression of the cord. He was started on four-drug anti-tubercular treatment. At 6-month follow-up, he had marked neurological improvement. MRI screening of the entire spine showed complete resolution of the disease. Contiguous epidural involvement of the entire spine by tubercular pathology has never been reported before. We suggest that screening of the entire spine should be considered in select cases of spinal tuberculosis based on symptomatology.

Tuberculous spondylitis--analysis of 22 cases

Tuberculous spondylitis (TS) frequently poses both diagnostic and therapeutic challenges. The clinical symptoms, radiological imaging studies and laboratory tests are quite often inconclusive in the early stages of the disease.

GOAL

To identify early clinical symptoms, review results from radiological imaging studies and laboratory tests to establish their diagnostic value and determine the effect of conservative therapy in patients with early TS.

RESULTS

Twenty two (22) patients with TS subjected to conservative therapy were studied. Medullary compression syndrome was found in 10 patients. The highest diagnostic value was established by Magnetic Resonance Imaging (MRI) data for discitis engaging two adjacent vertebrae and QuantiFERON TB Gold and T SPOT.TB tests. The effect of the disease on 12 patients, whose treatment had started before the collapse of the bodies of the vertebrae was non-occurrence of any residual deformity of the spinal column. The effect on 9 patients, whose therapy started at a later stage was a recovery of the neurological deficiency and deformity occurrence of various degrees.

CONCLUSION

Repetitive lateral plain radiographs, MRI and QuantiFERON TB Gold test have proven of highest diagnostic value at this stage of the disease in our patients. The presence of clinical data, accelerated ESR levels, plain radiography and MRI evidence of an inflammatory process preceding the occurrence of bone destruction and the formation of paravertebral soft tissue collection provide sufficient reasons to conduct QuantiFERON TB Gold or T SPOT.TB testing and start an antituberculous therapy. In the frequent cases when the diagnosis cannot be sufficiently proven, we recommend empirical anti-tuberculous therapy.

[Surgical retreatment of thoracic and thoracolumbar spinal tuberculosis]

OBJECTIVE

To explore the surgical measures and principles in the retreatment of thoracic and thoracolumbar spinal tuberculosis.

METHODS

Thirty retreatment cases of thoracic and thoracolumbar spinal tuberculosis in recent 3 years were retrospectively analyzed. The patients were hospitalized by inadequate decompression of spinal canal, tubercular toxic symptoms or sinuses. The disease course was an average of 6 months from the last operation. The patients were given anti-tuberculosis therapy according to the adjusted regimens for 2 - 8 weeks before reoperations. Ten cases were performed by anterior approach with debridement, 6 cases anterior approach (debridement, fusion & plate-screw fixation) and 4 cases dislodgment of transpedicular screw system and routine surgical treatment by anterior approach in one primary term. Debridement, Ti-mesh implantation and bone grafting, without taking out of the transpedicular screw systems was performed in 1 case of elder patient older than 70 years old with transpedicular screw system fixation. Nine cases underwent sinuses excision, debridement and dislodgment of transpedicular screw system in first attempt. After 2 - 3 weeks since incision healing, anterior approach was routinely performed. The tissues and liquor puris debrided from focus were sent for pathological examination, Bacillus tuberculosis detection and culture and drug sensitivity test. The patients were given anti-tuberculosis therapy according to the results of drug sensitivity test for 1 - 1.5 years. Follow-ups included relapse rate, fusion of bone graft and status of neurological recovery, etc.

RESULTS

All 30 cases recovered from peroperation. The follow-up period ranged from 3 to 32 months (mean: 18 months). Fourteen of 21 cases with neurological deficits recovered partially or totally. All incisions had primary healing. No relapse occurred within follow-up period. All cases were confirmed with Bacillus tuberculosis infection by pathology. Bacillus tuberculosis was detected and cultured successfully in 16 cases (53.3%). Nine strains (56.3%) were drug resistant and in which 4 strains (25.0%) were multi-drug resistant.

CONCLUSION

For the retreatment of thoracic and thoracolumbar spinal tuberculosis, targeted chemotherapy, thorough debridement and reasonable operative options are key to therapeutic success.

[A case of pulmonary tuberculosis complicated with spinal caries improved by the nutrition management of percutaneous endoscopic gastrostomy]

The case was 71-year-old woman. She was diagnosed as drug sensitive pulmonary tuberculosis (bII3 by the GAKKAI classification) and the chemotherapy with INH, RFP, EB and PZA was started. Two months later back pain and hemiparesis of both lower limbs appeared and it was diagnosed as caries of the 10th thoracic vertebrae. Because she was confined to bed and impossible to eat orally, the parenteral-hyperalimentaiton therapy was started with the central vein catheter. Howerer, nutritional state, pulmonary tuberculosis lesions and caries symptoms deteriorated. Then percutaneous endoscopic gastrostomy was performed and enteral nutrition was started. Since then nutritional state and tuberculosis lesions including caries improved gradually. It was estimated that the enteral nutrition brought about recovery of function and immunity of her digestive tract. For patients with advanced tuberculosis with poor nutritional state, the enteral nutrition is a useful adjuvant therapy, and the gastrostoma is considered to be one of the effective administrational routes when oral ingestion is difficult.

[Tuberculous spondylitis in children and adolescents: results of treatment]

The results of treatment for tuberculous spondylitis were studied in 160 children and adolescents receiving different chemotherapy regimens and in 145 after application of the currently available surgical methods. When an individual regimen was used in 1990-2000, recovery was achieved in 90.8 +/- 2.9% of cases; recurrent vertebral processes were observed in 7.1 +/- 2.5%. With the routine regimen, controlled treatment was terminated in 81.0 +/- 5.2% of cases and the number of recurrent vertebral processes was increased by 11.8 +/- 4.6%. With the DOTS-Plus regimen, treatment was completed in 91.0 +/- 4.1% of cases. Mycobacterium tuberculosis cultures were isolated from postoperative biopsy specimens in 6.8 +/- 3.5% of the 154 operated patients. The author presents the results of reconstructive operations using a free-pedicle autograft and a myovascular graft. In the late period, the operated vertebral portion was fixed to form a bone block in 83.3 +/- 5.6 to 88.0 +/- 7.9% of cases. There was an increase in spinal deformity in patients with a disseminated vertebral process.

[Spinal cord involvement by tuberculosis]

INTRODUCTION

We are observing an increase of patients with tuberculosis in Spain. Within the forms of extrapulmonary presentation, the involvement of the central nervous system by the bacillus that cause this disease is a relatively frequent location. Although sometimes is affected the spinal cord of secondary form, rarely is observed isolated involvement.

DEVELOPMENT AND CONCLUSIONS

We describe the diverse forms of spinal cord tuberculosis presentation, attending of its location within the spinal cord or adjacent annexes, in order that the clinician knows and remembers this infrequent but possible infection of the spinal cord, because their knowledge and prompt treatment modifies clearly their final prognosis. We analyze the treatment rules for each case according to the last recommendations, and finally, the differences in two groups of population, immunodepressant patients, like human immunodeficiency virus infected patients, as well as in paediatric age patients, because both groups have more possibility of tuberculosis infection generally, and therefore spinal cord involvement, with a differential clinical and therapeutic behaviour.
