Conservative management for pediatric craniocervical Pott's disease: A case study and literature review.

Craniocervical Pott's disease is rare, particularly in the pediatric population. The importance of motion preservation in this age group renders managing this disease even more challenging. The literature regarding craniocervical Pott's disease comes from endemic regions. Most authors will agree on early surgical intervention in cases of neurological compromise or severe instability, while patients with minimal symptoms will do well with conservative management. Controversy remains when patients are mildly symptomatic but with imaging findings concerning for significant instability. Here, we present the case of a 15-year-old male presenting with craniocervical tuberculoma with radiographic instability and advanced bony destruction without overt neurological deficits. He was managed with a rigid cervical collar and completed 1 year of anti-tuberculosis therapy. At 1-year follow-up, he had an intact range of motion, was pain-free, and remained neurologically intact. Although this case suggests good outcomes with conservative management are possible, more long-term follow-up is required to assess the need for delayed surgical intervention in this unique population.

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.

Unusual presentation of Pott disease and diagnostic challenges in a resource-limited setting: a case report.

BACKGROUND: Pott disease is rare and responsible for only 1%-2% of all tuberculosis cases. It poses diagnostic challenges in resource-limited settings due to unusual presentation and limited investigative capacity, resulting in debilitating sequelae if diagnosed late. CASE PRESENTATION: We present a case of severe Pott disease of the lumbar spine, with a large paravertebral abscess tracking down to the gluteal region in a 27-year-old Black African Ugandan woman living with human immunodeficiency virus, whose main complaint was right lower abdominal pain. She was initially misdiagnosed from the peripheral clinics as a case of lumbago and later with a psoas abscess. The diagnosis of severe Pott disease was established at the regional referral hospital following an abdominal computed tomography scan, and the patient was appropriately initiated on anti-tuberculosis drugs. However, only abscess drainage and provision of a lumbar corset were possible, with no neurosurgical intervention done on the spine due to financial constraints. Clinical review at 2, 6, and 12 months revealed improvement. CONCLUSIONS: Pott disease may present with non-specific symptoms such as abdominal pain resulting from pressure effects of an expansile cold abscess. This, coupled with limited diagnostic capacity in resource-limited settings; results in significant morbidity and possible mortality. Hence, there is need to train clinicians to increase their index of suspicion and equip health units with basic radiological equipment, such as x-ray, for timely detection and subsequent management of Pott disease.

Diagnosis and Treatment of Skipped Multifocal Spinal Tuberculosis Lesions.

Spinal tuberculosis, also known as Pott's disease or tuberculous spondylitis, is usually secondary to primary infection in the lungs or other systems, and in most instances, is thought to be transmitted via blood. Typical manifestations of infection include narrowing of the intervertebral disc by erosion and bone destruction of adjacent vertebrae. Atypical spinal tuberculosis is a specific type of spinal tuberculosis. It mainly consists of single vertebral lesions, single posterior structure lesions, multiple vertebral lesions, and intra-spinal lesions. Skipped multifocal spinal tuberculosis is one of these types and is characterized by two or more vertebral lesions without the involvement of the adjoining intervertebral discs, regardless of their location. To date, only a few cases have been reported. Upon clinical admission, it can be treated conservatively or surgically, depending on the patient's symptoms. In addition, gene or biological therapies are being investigated. However, because of the exceptional imaging findings and insidious symptoms, it is often misdiagnosed as a neoplastic lesion, osteoporotic fracture, or other infectious spondylitis, increasing the risk of neurological deficit and kyphotic deformity, and delaying the optimal treatment window. In this study, we review the diagnosis and treatment strategies for skipped multifocal spinal tuberculosis lesions and enumerate the common differential diagnoses, to provide reference and guidance for clinical treatment and diagnosis direction.

Lest we forget spinal tuberculosis (Potts's spine): Case series with unusual presentation.

Pott's disease, also known as TB spondylitis, is a very uncommon extrapulmonary infection caused by Mycobacterium tuberculosis. As its prevalence is not high it can easily be underdiagnosed. Magnetic resonance imaging (MRI), computed tomographic (CT) guided needle aspiration, or biopsy are known to be the best techniques for early histopathological diagnosis along with confirmation by microbiological results. Ziehl Neelson stain (ZN) can detect Mycobacterium infections when clinically suspected samples are adequate and optimally stained. No single method or simple guideline can diagnose spinal tuberculosis. Early diagnosis and prompt treatment are necessary to prevent permanent neurological disability and to minimize spinal deformity. We are reporting three cases of Potts disease which could have been easily missed if we would have relied on one single investigation.

A Comparative Study of Diagnosis and Treatment of Pott's Spine Amongst Specialists and Super Specialists in India.

Background and Objective: There is a paucity of guidelines about the diagnosis and management of Pott's spine. In this study, we report the pattern of practice of diagnosis and treatment of Pott's spine among the specialists and super-specialists in India. Subject and Methods: Response to a 22-item questionnaire regarding the diagnosis and treatment of Pott's spine has been reported. The responses were compared between medical and surgical specialists, residents and consultants, and specialists and super-specialists. There were 84 responders: 42 physicians and 42 surgeons; 48 residents and 36 faculty or consultants; 53 specialists and 31 super-specialists. Results: Thirty-eight responders rarely recommended biopsy whereas others recommended biopsy more frequently, especially the surgeons (P < 0.007). Twenty-five responders recommended immobilization even in an asymptomatic patient whereas 38 would immobilize those with neurological involvement only. All but 4 responders would repeat imaging at different time points. The response of medical treatment was judged at 1 month by 53, and 3 months by 26 responders. Surgery was recommended in a minority of patients-in those with neurological involvement or abscess. Surgeons more frequently biopsied, immobilized the patients, and recommended surgery compared to the physicians. The residents also recommended biopsy and recommended immobilization more frequently compared to consultants or faculty members. Super-specialists more frequently recommended biopsy compared to specialists. Conclusion: There is marked variation in investigations and treatment of Pott's spine patients, suggesting the need for consensus or evidence-based guidelines.

Clinical Conundrum: A Complex Case of Pott Disease in Pregnancy.

Spinal tuberculosis (TB) is a rare form of extrapulmonary TB that can be clinically difficult to diagnose, particularly in pregnancy. This 24-year-old G2, P0 patient was diagnosed at 19 weeks gestation, 2 days after a protracted admission for hyperemesis gravidarum, COVID-19 infection, and unexplained transaminitis with bilateral lower limb weakness and urinary retention. She underwent emergent spinal decompression surgery with expectant management on intravenous antitubercular medication and cesarean delivery at 343 weeks gestation. Spinal tuberculosis is a difficult diagnosis, impacted by medical comorbidities, pregnancy, and diagnostic bias. This case describes successful antenatal management of spinal tuberculosis and highlights the importance of interdisciplinary care.

Treatment response and complications during management of Pott's spine.

The global incidence of TB in 2016 was 10.4 million and India accounts for a quarter of the global burden of TB. It is estimated that there are 2.79 million people with TB in India. About 10% of extra pulmonary TB involves bone and joints. Spinal TB accounts for half the cases of skeletal TB. The incidence of spinal TB is 1-4% of total TB cases, then it is estimated that only in India approximately 60,000 spinal TB cases exist. To report the pattern of recovery and predictors of outcome of Pott's spine. The intervention comprised of four drug antitubercular treatment, rest, immobilization, and ultrasonography or computerized tomography guided aspiration or biopsy as indicated outcome measures were six months Nurick grade, and mRS and complications like drug induced hepatitis (DIH) and paradoxical worsening. Seventy-three patients with Pott's spine, median age 36 (11-73) years, 32 (43.8%) females were included. The neurological signs were present in 44 (64.4%) patients. At six months, median Nurick grade improved from 4 to 2 and;and 70% patients had a good outcome as defined by mRS.The predictors of poor outcome were weight loss, non-ambulatory state on admission and paradoxical worsening. It is concluded that neurological involvement in Pott's spine was present in 64% patients, paradoxical worsening (deterioration in symptoms after one month of ATT) in 11% and DIH in 16%. Weight loss, non-ambulatory state on admission and paradoxical worsening predicted poor outcome.

Study on the expression level of NF-κB and clinical evaluations in spinal tuberculosis patients.

Spinal tuberculosis or tuberculous spondylitis is one of the most common types of skeletal tuberculosis. Complications of the spine and spinal cord tuberculosis include destruction of the vertebrae, deformity, and paraplegia. Since in some patients, the clinical manifestations of tuberculosis are unusual and timely diagnosis and treatment of this disease can prevent its serious consequences, so in the present study, some cases of rare manifestations of tuberculosis were investigated. The expression of the NF-κB gene in these patients was also evaluated. In this regard, 36 patients with spinal tuberculosis and 30 healthy individuals (as a control group) were assessed. Clinical symptoms, imaging, laboratory tests, pathology, and response to treatment related to patients with spinal tuberculosis and spinal cord tuberculosis were evaluated. NF-κB expression was also evaluated using the PCR technique in peripheral white blood cell samples. The obtained results were analyzed using SPSS ver. 16, χ2 and T-test statistical methods. Mann-Whitney U test and Kruskal-Wallis non-parametric tests were used to analyze non-parametric data. The results showed that out of 36 cases of spinal tuberculosis, 29 cases had spinal tuberculosis, five cases had tuberculous radiculomyelitis, one case had spinal intramedullary tuberculoma, and one case had syringomyelia. 52.78% of patients were male, and 70% of cases were observed between the ages of 35 and 55 years. Fever and back pain were seen in more than 80% of cases. The study of NF-κB expression in the control and case groups showed that the NF-κB expression in the case group increased compared to the control group. This increase was statistically significant (P = 0.0071). In general, in the present study, the methods of clinical diagnosis of spinal tuberculosis were evaluated. Also, the amount of NF-κB transcription factor was evaluated as an effective genetic factor in the diagnosis of this disease.

Loss to long-term follow-up in children with spinal tuberculosis: a retrospective cohort study at a tertiary hospital in the Western Cape, South Africa.

Introduction: children with spinal tuberculosis (TB) are at risk of kyphotic deformity both during and after the active phase of the disease. Management guidelines include follow-up until skeletal maturity. Little is known about adherence to this recommendation. This study aimed to investigate loss to long-term spine clinic follow-up (LTFU) among children with spinal TB at a tertiary hospital in the Western Cape Province, South Africa. Methods: this retrospective cohort study included all children diagnosed with spinal TB at Tygerberg Hospital between January 2012 and December 2015. Spine clinic follow-up was investigated for five years following diagnosis. Relevant surgical interventions and re-presentation were evaluated until 31st December 2020. Results: thirty-two children, median age 6 years (range 1-14 years), were diagnosed with spinal TB and intended for spine clinic follow-up. Twenty-seven (84%) children were LTFU within five years of diagnosis with 16 (50%) LTFU within 10.5 months. Among children in follow-up, one child had further surgery for progression of deformity two years from diagnosis and one child had further surgery for new-onset neurological deficit eight years from diagnosis. Conclusion: most children with spinal TB did not receive the recommended follow-up until skeletal maturity. Without further data on these children, the clinical significance of this LTFU could not be evaluated. Further studies are needed to investigate sequelae during skeletal maturation in the context of current management for paediatric spinal TB.

Spinal Tuberculosis. / Tuberkulose der Wirbelsäule.

Tuberculosis is one of the most common infectious diseases worldwide. The frequency in Germany is low, however, an increase has been observed in the past few years. The incidence of extrapulmonary manifestation accounts for up to 10 to 20%. In 50% of these cases the spinal column is affected. Although literature reveals worldwide experiences in the treatment, in Germany spinal tuberculosis remains a rarity. Different pitfalls and specific characteristics regarding diagnosis and therapy are to consider. Therefore, a presentation of these specifics and their discussion based on the available literature will be presented. The purpose is to achieve an increase in awareness regarding this, in our latitudes, rare disease.

Cervical spine TB - Current concepts in management.

OBJECTIVE: Cervical tubercular disease (CTB) is a rare pathology and constitutes 3-5% of all spinal TB. It includes atlantoaxial TB and sub-axial TB. As the literature evidence on this subject is scarce, majority of issues concerning CTB are still controversial. The current narrative review comprehensively discusses the various aspects related to CTB. Literature search: An elaborate search was made using keywords cervical tuberculosis, atlantoaxial tuberculosis, sub-axial tuberculosis, and cervico-thoracic tuberculosis, on pubmed and google (scholar.google.com) databases on 2 December 2020. We identified crucial questions regarding CTB and included relevant articles pertaining to them. RESULTS: The initial search using keywords cervical tuberculosis, atlantoaxial tuberculosis, sub-axial tuberculosis, and cervico-thoracic tuberculosis yielded 4128, 76, 3 and 9 articles on 'pubmed' database, respectively. A similar search using the aforementioned keywords yielded 1,96,000, 2130, 117 and 728 articles on 'google scholar' database. The initial screening resulted in the identification of 178 articles. Full manuscripts were obtained for these articles and thoroughly scrutinised at the second stage. Review articles, randomised controlled trials and level 1 studies were given preference. Overall, 41 articles were included. CONCLUSION: AATB and SACTB constitute 0.3 to 1% and 3% of spinal TB, respectively. The incidence of neuro-deficit in CTB is significantly more than other spinal TB. The general principles of management of CTB are similar to spinal TB elsewhere and medical therapy remains the cornerstone. Surgery is advocated in specific scenarios involving gross neuro-deficit, later stages of disease with significant bony/ligamentous disruptions, altered sagittal balance, drug resistance, and poor response to medications. The surgical approaches for AATB include anterior-alone, posterior-alone and combined approaches, although posterior access is the most preferred. Most of the studies on SACTB have supported the role of anterior approach. Additionally, posterior stabilisation may be necessary in specific scenarios. The overall long-term outcome in CTB is favourable.

The efficacy of single posterior debridement, bone grafting and instrumentation for the treatment of thoracic spinal tuberculosis.

The aim of this study was to investigate the clinical efficacy of single posterior debridement, bone grafting and instrumentation for the treatment of thoracic spinal tuberculosis in adult patients. A retrospective analysis was conducted between June 2013 and September 2017of 88 adult patients with thoracic spinal tuberculosis. All patients were treated with single posterior debridement, bone grafting and instrumentation. The clinical manifestations and laboratory and imageological results were subsequently analysed. All patients were followed for 40.6 ± 4.1 months (range, 36-48 m). Bony fusion was achieved in all bone grafts of thoracic vertebrae. The visual analogue scale scores, erythrocyte sedimentation rate and C-reactive protein levels 6 weeks after surgery and at the final follow up were significantly lower than the preoperative levels (P < 0.05). The postoperative and final follow up kyphosis angles were both significantly smaller than the preoperative kyphosis angles (P < 0.05). The postoperative angle correction rate reached 81.5% and the postoperative angle loss reached only 4.1%. At the last follow up, American Spinal Injury Association improvement was significant, compared with the preoperative levels (P < 0.05). The single posterior approach can achieve satisfactory clinical outcomes in the treatment of thoracic spinal tuberculosis.

This increase was statistically significant (P = 0.0071). In general, in the present study, the methods of clinical diagnosis of spinal tuberculosis were evaluated. Also, the amount of NF-κB transcription factor was evaluated as an effective genetic factor in the diagnosis of this disease.

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.

Clinical efficacy of three types of autogenous bone grafts in treatment of single-segment thoracic tuberculosis: A retrospective cohort study.

A retrospective study investigated and compared the results of lamina with spinous process (LSP), transverse process strut (TPS) and iliac graft (IG) as bone graft in thoracic single-segment spinal tuberculosis(TB) with the one-stage posterior approach of debridement, fusion and internal instrumentation. 99 patients treated from January 2012 to December 2015 were reviewed. LSP was performed in 35 patients (group A), TPS was undertaken in 33 patients (group B), and IG was carried out in 31 patients (group C). Surgical time, blood loss, hospitalization time, drainage volume, and follow-up (FU) duration were recorded. The visual analog scale (VAS), Oswestry Disability Index (ODI), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), American Spinal Injury Association (ASIA) grade, segmental angle, intervertebral height and bone fusion time were compared between preoperative and final FU. All the patients were followed up for a mean 43.90±10.39 months in group A, 45.30±6.20 months in group B, 44.32±7.17 months in group C without difference(P>0.05). The mean age was younger, the blood loss was less, the hospitalization time and the surgical time were shorter in group A than those in group B and C (P<0.05). The drainage volume was less in group A than that in group B and group C. The CRP, ESR, VAS, and ODI were significantly decreased and there were no significant difference among the groups at the final FU. The neurological function after surgery was improved compared with preoperation among the groups. The bony fusion at a mean time 12.90±3.91 months in group A was longer than that in group B (6.75±1.55 months) and group C (5.52±1.64 months) (P<0.05). No significant difference was found at the mean segmental angle, mean intervetebral height of preoperation and final FU among the groups (P>0.05). In conclusion, the LSP and TPS as bone graft are reliable, safe, and effective for single-segment stability reconstruction for surgical management of thoracic TB and TPS could be new bone graft methods.

Cervical spine tuberculosis.

Tuberculosis of the cervical spine differs from other vertebral localizations by its extreme rarity, the clinical images are very diversified, the radiological measurements allow a good diagnostic orientation and specifically the MRI which allows a multi-planar study of the various lesions. Only bacteriological evidence can confirm the diagnosis. The treatment is based on a 12-month antituberculosis multidrug therapy and much debate upon the surgical indication. In our case, the patient presented with bilateral cervicobrachialgia with pain on examination at the mobilization of the cervical spine. A standard X-ray, a cervical CT scan, and a cervical MRI were performed, showing a C4 vertebral body compression of a probably infectious origin. The biopsy confirmed the diagnosis of a Cervical Pott's Disease that had been treated with anterior arthrodesis and TB treatment with rehabilitation, the patients' neurological symptoms improved, and he was doing well.

Drug resistant TB spine in a two year old child: A case report.

Spinal tuberculosis (TB) is a disease of high morbidity that is associated with deformity and neurological sequelae, especially in growing children. Children diagnosed with spinal TB need to be monitored closely for clinical improvements. Previous history of antituberculous therapy (ATT), poor adherence to previous ATT, contact with persons having known drug-resistant (DR) TB, or clinical worsening despite regular ATT are strong indicators for the diagnosis of DR TB of the spine. We report a case of spinal DRTB in a two year old child with no previous history of ATT and contact with a person on irregular treatment for drug sensitive TB that did not show regression of the spinal lesions despite standard ATT.

[Tuberculous Spondylitis - Diagnosis and Management]. / Tuberkulöse Spondylitis ­ Diagnose und 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.

Loss to follow-up among patients diagnosed with spinal tuberculosis at a tertiary hospital in Western Cape Province, South Africa: A retrospective cohort study.

BACKGROUND: Patients diagnosed with spinal tuberculosis (TB) at a major tertiary hospital in Western Cape Province, South Africa, are required to attend regular follow-up at the hospital's outpatient spine clinic and to remain on TB treatment for at least 9 months. This follow-up and lengthy treatment is intended to allow for specialist monitoring of TB treatment response and early identification of secondary complications, and to reduce the risk of recurrence. However, little is known about adherence to these recommendations. OBJECTIVES: The main objectives were to describe (i) loss to spine clinic follow-up (LTFU), and (ii) TB treatment duration among patients diagnosed with spinal TB at the hospital. Secondary objectives were to investigate (i) the association between LTFU and treatment duration, and (ii) factors associated with LTFU. METHODS: This retrospective cohort study included 173 adults diagnosed with spinal TB between 2012 and 2015 and investigated follow-up within 2 years from diagnosis. Clinical, demographic and appointment data were obtained from hospital records and a dataset provided by the provincial Department of Health. LTFU was presented as frequency (%) and as a survival analysis. TB treatment duration was reported as frequency <9 months or ≥9 months, and the association between LTFU and <9 months of treatment was investigated using relative risk (RR) with 95% confidence intervals (CIs). Univariate associations between explanatory variables and LTFU were investigated using simple logistic regression analysis. RESULTS: Patients had a median (interquartile range) age of 36 (29 - 48) years and included 98 females (57%) and 151 individuals (87%) residing <50 km from the hospital. Primary outcomes were that 129 patients (75%) were LTFU within 2 years of diagnosis and 45 (30%) completed <9 months of treatment. The RR of <9 months of treatment was 1.62 (95% CI 1.39 - 1.88) among those LTFU compared with those retained in follow-up. LTFU was not associated with any of the clinical or demographic variables investigated. CONCLUSIONS: Three-quarters of the patients did not complete follow-up at the tertiary hospital spine clinic, and almost one in three received <9 months of TB treatment. Remaining in spine clinic follow-up was significantly associated with receiving at least the minimum duration of TB treatment. However, LTFU could not be predicted from routine clinical and demographic information and is likely to be related to factors not accounted for in the current analysis.
