Chest Wall Hydatid Disease: Surgical management and risk Factors for Recurrence and Mortality

Background Hydatidosis of the thoracic wall differs from other hydatid localizations in its pathophysiology, diagnostic, and therapeutic management. It is a little-studied entity. The objectives of our work were to describe its surgical management and to analyze the factors that may influence recurrence and mortality. Methods A retrospective, descriptive, longitudinal, and multicenter study on four university hospital surgical centers of Tunis, from January 1995 to December 2022 including operated hydatid cysts of the thoracic wall. Overall survival (OS) and cumulative recurrence rates were calculated. Univariate and multivariable Cox regression analyses were performed to identify recurrence and mortality risk factors. Results Forty-nine patients were included. The mean age was 41 ± 17 years [8-76]. The main presenting sign was thoracic parietal swelling (n=22). Chest ultrasound and CT scan showed multivesicular formation in 17 and 33 cases, respectively. Muscle involvement was in the intercostal (n=4), paravertebral (n=13), and pectoralis major (n=3) muscles. Bone involvement was vertebral (n=11), costal (n=12), costo-vertebral (n=21) and sternal (n=2). A posterolateral thoracotomy was performed (n=20). Surgical excision at various levels of the chest wall with spinal stabilization (n=15) was performed. Sixty-three percent of the patients received antiparasitic medical treatment. Recurrence occurred in 37% of cases. Four patients died from hydatidosis-related complications. Factors could be independently associated with recurrence such as male gender, and vertebral involvement. The presence of a visceral hydatid cyst located at a distance from the parietal lesion at the time of diagnosis and the occurrence of postoperative infectious complications could increase mortality. Conclusions Chest wall hydatidosis represents a rare medical condition where surgery remains the preferred treatment modality. However, it carries a substantial burden of morbidity and mortality, influenced by various factors. Further large-scale studies are necessary to gain a deeper understanding of these factors and to optimize management strategies accordingly.

Infected Primary Bone Mantle Cell Lymphoma with Multiple Vertebral Involvement

Primary vertebral lymphoma is an exceedingly rare entity. We hereby report a case of a 67-year-old male who presented to our department with fever, weight loss, and progressively worsening lower back pain radiating to the right hip. Physical examination showed pain on percussion of the dorsal and lumbar spine and tenderness on palpation of the right upper thigh area. The radiographic findings revealed numerous vertebral lesions with a right psoas abscess extending to the right upper thigh. Intravenous antibiotic therapy was initiated and the patient underwent an incision and drainage of the psoas abscess with a favourable outcome. However, given the suspicious imaging findings of the osseous lesions suggestive of malignancy, a vertebral biopsy was performed and yielded histo-pathological findings consistent with bone mantle cell lymphoma. To the best of our knowledge, this is the first case of an infected primary bone mantle cell lymphoma with multiple vertebral involvement. The diagnosis is challenging and can be confused with other diseases.

Preliminary Application of Bilateral Submandibular Horizontal Incision in the Treatment of Upper Cervical Tumors.

The upper cervical spine has a complex anatomical structure, making anterior surgical approaches challenging and prone to complications. This study aims to explore the use of bilateral submandibular incisions to provide safer and more convenient exposure of the upper cervical spine and to assess the feasibility of this approach for anterior surgical treatment of complex upper cervical diseases. From November 2019 to August 2021, three patients with malignant tumors of the upper cervical spine were subjected to an anterior-posterior combined approach for cervical tumor resection. The cohort consisted of one male and two females, aged between 41 and 51 years. The anterior approach began with a submandibular incision, followed by blunt dissection through the prevertebral muscles to expose the diseased vertebra. Subsequently, the diseased vertebra was excised, and either a titanium cage or a pre-customized 3D-printed artificial vertebral body was implanted anteriorly. Then, posterior fixation of the cervical spine was performed using pedicle screws to provide additional stability. Follow-up ranged from 8 to 34 months. All patients experienced varying degrees of pain relief within 24 hours post-operation. Frankel grading showed improvement by at least one grade in all three cases. Regular X-ray and magnetic resonance imaging examinations revealed no tumor recurrence or involvement of adjacent vertebrae in the surgical area. The anterior bilateral submandibular horizontal incision approach offers comprehensive exposure of the anatomical structures of the upper cervical spine. This approach introduces a new option for the anterior treatment of upper cervical spine diseases.

Survey of spinal tuberculosis in Basrah

Background. Tuberculous spondylitis (TS) or spinal tuberculosis is secondary either to pulmonary or intestinal tuberculosis and may be the initial manifestation of tuberculosis (TB). Spinal TB also called Pott’s disease is by definition, an advanced severe disease, requiring accurate evaluation and aggressive systemic therapy. Objective. This study was conducted to demonstrate the prevalence and clinical, laboratory, and management characteristics of patients with spinal tuberculosis in Basrah governorate. Methods. A cross-sectional descriptive retrospective and prospective study was conducted during the period of March 2020 to December 2021. All cases either registered at the tuberculous center / Basrah Health Director were viewed by phone calling or recall or newly diagnosed with spinal tuberculous which attended to Basrah Teaching Hospital. Those patients were followed after diagnosis and treatment initiation for any clinical improvement, worsening or no improvement after diagnosis. Results. Among 51 enrolled patients with spinal tuberculosis in this study, the age distribution was 20-39 years old 23 (45.09%). Most of the patients were males (32) with rates 62.74%. The most common site of vertebral involvement is dorsal segment 29 (56.86%). The most common presenting complaints were: back pain in 49 patients (96.07%). Regarding the examination findings, 2(13.33%) with deformity either kyphotic or gibbous deformity. Most of the examined patients had a power grade 1-3/5 (93.33%) in the lower limbs. Out of the 4 cases of cervical tuberculosis, all of them had been managed conservatively, while 6 out of 16 cases (37.5%) diagnosed with lumber lesions were managed conservatively, and 10 cases (62.5%) were managed surgically. Conclusion. The prevalence and characteristics of patients with spinal TB follow the global trend, although some differences were recorded, but it was not that significant. The surgical approach is still superior to the conservative one in the improvement of neurological deficits.

MRI findings and classification of brucella spondylitis: a China multicenter study.

To propose a magnetic resonance imaging (MRI) classification of brucellosis spondylitis (BS) to determine a standard treatment method and a standard of post-treatment MRI follow-up. This is a multicenter retrospective cohort study. All patients diagnosed with BS at six hospitals for 12years, were included in the study. Data were collected retrospectively from the medical records of the patients. The classification of the cases was based on MRI. We analyzed MRI features of BS was categorized them into three types. Six hundred fifteen patients were included in the study, 78.9% of whom were males. The mean age was 53.05 ± 11.06years. Involvement of single vertebrae occurred in 6.2% of patients, while 72.7% involved two vertebrae and 21.1% involvement of more than two vertebrae. The most common of the lumbar spine was 64.6%. The main findings of MRI were affected vertebral endplate 2/3 above (60.7%), intervertebral space narrow (77.9%), intervertebral disc involvement (83.6%), paravertebral abscess (50.9%), disc abscess (49.6%), epidural abscess (43.3%), vertebra height change (22.1%), psoas abscess (22.0%), and abnormal vertebral accessory (10.2%). MR imaging of BS was categorized into three types. Type I: 57 (9.3%) patients; Type II: 526 (85.5%) patients, including IIa (26.5%), IIb (36.9%), and IIc (22.1%); Type IV: vertebral appendage type, 63 (10.2%) cases; Type III: 32 (5.2%) patients. MRI features of multicenter data can provide theoretical support for diagnosing BS. MRI classification of BS can afford better help for clinical treatment and follow-up after clinical treatment.

Association between nutritional scores and multilevel vertebral involvement in tubercular spine: a retrospective cohort study.

The objective of this study is to evaluate the prognostic value of nutritional scores comprising the Controlling Nutritional Status (CONUT) score and the Prognostic Nutritional Index (PNI), in prediction of multilevel vertebral involvement (> 2 vertebra) in Spinal Tuberculosis (STB). Retrospective analysis of 39 STB patients was conducted to assess nutritional indices (CONUT and PNI) and the numbers of vertebral affection. Spearman's correlation was used to examine the association between these variables. Receiver Operating Characteristic (ROC) curves were utilized to determine optimal cutoff values, with Area Under the Curve (AUROC) evaluation. Additionally, multiple logistic regression was performed as a predictive model. There were 24 males and 15 females, with a mean BMI of 18.88kg/m² (± 1.37). Spearman's correlation analysis revealed negative correlations between BMI, PNI (rho - 0.68, p < 0.001) and multilevel vertebra involvement, while ESR (rho 0.83, p < 0.001), CRP (rho 0.81, p < 0.001), and CONUT score (rho 0.83, p < 0.001) positively correlated with multilevel vertebral affection (> 2 vertebra). Age and comorbidities showed no correlation with the level of vertebral affection. ROC analysis revealed a CONUT Score ≥ 3 cutoff (sensitivity-95.7%, specificity-87.5%) and PNI ≤ 38.605 (sensitivity-78.3%, specificity-93.8%) for predicting multilevel STB (> 2). PNI exhibited superior specificity and positive predictive value where as CONUT score was a better parameter for sensitivity, negative predictive value and diagnostic accuracy. Both CONUT score and PNI were significant predictors of vertebral involvement in univariate analysis, with multivariate analysis identifying CONUT score as the sole predictor of multilevel vertebral affection. Nutritional scores, including CONUT score and PNI, emerged as significant predictors of multilevel STB. CONUT score displayed superior sensitivity, negative predictive value, and overall diagnostic accuracy, while PNI served as a nutritional marker with high specificity and positive predictive value in predicting multilevel involvement in spinal tuberculosis.

Anatomical and Radiological Findings of Abnormal Calcified Structures within and around the Foramen Transversarium and Its Clinical Implications.

The foramen transversarium is a vital anatomical structure found in the cervical vertebrae of the spine. Typically, it serves as a passageway for important neurovascular structures, including the vertebral artery and vein, as well as the vertebral nerve. However, abnormal calcification or ossification of soft tissues in and around this area can lead to various clinical implications. Understanding the presence and implications of abnormal ossified structures in and around the foramen transversarium is crucial for clinicians involved in the diagnosis and management of cervical spine disorders. Accordingly, this present study was designed to evaluate the abnormal ossified structures anatomically and radiologically within and around the foramen transversarium. This study was conducted on 182 (26 sets of cervical vertebrae) dried human cervical vertebrae obtained from the respective departments of anatomy and on 190 (95 males and 95 females) adult patients who visited the radiology department for neck-related problems such as stiff neck, neck/shoulder pain, dizziness, vertigo, imbalance, visual disturbances, and cognitive impairment. Among 182 examined cervical vertebrae, unilateral complete accessory foramen transversarium was found in 23 vertebrae (12.63%), bilateral complete in 19 (10.44%), bilateral incomplete in 6 (3.29%), unilateral complete double in 4 (2.19%), and unilateral complete absence of foramen transversarium in 3 (1.64%). Stenosis due to aberrant osteophytes was noted in 9 vertebrae (4.9%). Out of 190 patients, three males presented with cervical kyphosis, severe spinal canal stenosis, and spinal cord compression due to ossification of the posterior longitudinal ligament and osteophyte complexes at C3-C6, with the most significant compression at C5-C6. A thorough understanding of abnormal ossifications in and around the foramen transversarium is crucial for the management of cervical spine disorders; imaging modalities such as X-ray, computed tomography, and magnetic resonance imaging are crucial for recognizing and intervening in these cases, which is essential to prevent adverse neurological outcomes associated with vertebral artery involvement.

Posterior Spinal Fusion for Severe Kyphosis in a Child with Gaucher Disease: A Case Report and Review of the Literature

Background: Skeleton involvement is one of the most significant aspects of Gaucher disease (GD). However, the treatment for spinal involvement in GD among patients undergoing enzyme replacement therapy (ERT) is poorly characterized. We present a case of progressive kyphotic spinal deformity in a young child caused by vertebral involvement, which was managed by posterior spinal fusion without anterior spinal release under ERT. Case presentation: This is a retrospective study. A 10-year-old boy presenting with progression kyphosis (thoracic kyphotic angle of 113°) associated with type-IIIb GD had undergone posterior spinal fusion with segmental pedicle screw fixation (from T6-L3) and Ponte osteotomy. The patient went back to school without further brace protection. Proximal junctional kyphosis (PJK) was observed at 4 months postoperatively. Revision surgery was performed to prevent neurological impairment. Additional posterior spinal fusion from T2–T6 and decompressive laminectomy were performed during the revision surgery. A 2-year follow-up showed no recurrence of PJK and solid fusion was achieved in the patient under ERT and brace protection. Conclusions: Posterior spinal fusion without anterior spinal release is a good treatment option for severe spinal deformity in patients with GD. However, the fusion level and reinforced fixation require careful consideration. Revision surgery and brace protection is needed as long as PJK is observed.

CT, MRI, and PET/CT imaging features of thoracic spine epithelioid hemangioma: a retrospective observational study.

Epithelioid hemangioma (EH) is an intermediate locally aggressive tumor that consists of epithelioid cells and endothelial cell differentiation, which can occur at any age, but is most common between the ages of 30 and 40 years. EH in the thoracic spine is rare, and accurate diagnosis is critical to treatment planning. Our aim was to explore the imaging and clinical data of thoracic spine EH to improve the understanding of this rare disease. From January 1, 2018 to June 30, 2023, a database of thoracic spine masses was retrospectively reviewed. Five patients with histologically proven thoracic spine EH and complete imaging available were identified and analyzed. Computed tomography (CT) and magnetic resonance imaging (MRI) findings were evaluated separately by two radiologists with more than 10 years of experience. Positron emission tomography (PET)/CT was conducted by two nuclear medicine diagnostic technologists with at least 5 years of experience. The patients included three male and two female patients aged 23 to 56 years (mean age was 38.4 ± 14.3 years). All patients underwent CT, MRI, and 18F-FDG PET/CT examination before treatment. Four patients were limited to one vertebral involvement, only one patient had multiple vertebral involvement, and all tumors involved the accessories, including one involving the posterior ribs. The maximum diameter of the tumor ranged from 2.7 to 4.3. CT, MRI, and 18F-FDG PET/CT findings of thoracic spine EH have certain characteristics, and understanding these imaging findings will help to obtain accurate diagnosis before surgery.

Chronic Nonbacterial Osteomyelitis, Hidradenitis Suppurativa, and SAPHO Syndrome

Introduction: Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome may represent one side of a spectrum of disease that also includes chronic nonbacterial osteomyelitis. Case: A 23-year-old male with bone pain in the anterior chest, shoulder, clavicles, left elbow, and left ankle presented to rheumatology clinic after multiple evaluations for infectious osteomyelitis. Imaging and deep bone biopsies of affected areas were consistent with chronic osteomyelitis, with labs notable for elevated erythrocyte sedimentation rate, C-reactive protein, and positivity for HLA-B27. A full skin exam was consistent with hidradenitis suppurativa, and he was started on infliximab and methotrexate with improvement in both his osteoarticular and skin symptoms. Conclusions: Patients presenting with features of follicular occlusion or neutrophilic dermatoses in conjunction with bone pain should be evaluated for SAPHO/CNO. In patients with SAPHO/CNO with vertebral involvement, bisphosphonates in addition to anti-inflammatory medications (such as methotrexate and TNF-inhibitors) can be effective.

A ten-year experience of musculoskeletal tuberculosis at a tertiary care hospital in South India

BackgroundThe delayed identification and management of musculoskeletal tuberculosis (MSTB) poses substantial health challenges and leads to significant morbidity. This study aimed to collate ten years of hospital data and provide valuable insights into the clinical, diagnostics, and outcomes of the patients diagnosed with MSTB. MethodsA retrospective study was undertaken to review clinic records from 2013 to 2022 for all individuals diagnosed with MSTB in a tertiary care hospital in South India. ResultsOver a decade, 400 cases of MSTB were diagnosed, revealing 57 % males and 43 % females with a mean age of 43.2 ± 18.9 years. Spinal TB constituted 72 % of cases, with the most common involvement of thoracic vertebrae (50.9 %). Extra-spinal MSTB accounted for 28 %, prevalent more in the pediatric age group (p < 0.05). Surgical intervention was required for 80 % of spinal TB cases and 58 % of extra-spinal MSTB cases. The average follow-up duration was two years, with 73 % completing treatment. Unfortunately, seven patients died, and three experienced relapse. ConclusionSpinal TB is the most common type of MSTB and is predominant in young and middle-aged adults, while extra-spinal MSTB is more frequently observed in children. Where use of MRI facilitates early detection of spinal TB; histopathological and microbiological examination confirm the diagnosis. Combining anti-tubercular drugs with modern surgical approaches is essential for obtaining favorable outcomes and improving the quality of life of such patients. It is crucial to have advanced and affordable diagnostic facilities, along with increased public awareness, to reinforce tuberculosis control strategies.

Percutaneous Transforaminal Endoscopic Lumbar Foraminotomy in Stable Degenerative Lumbar Isthmic Spondylolisthesis with Radicular Leg Pain: A Retrospective Study.

Endoscopic surgery is a minimally invasive option for effectively addressing lumbar degenerative diseases. This study aimed to describe the specific technology of percutaneous transforaminal endoscopic lumbar foraminotomy (PTELF) as a therapeutic intervention for managing radicular leg pain (RLP) resulting from stable degenerative lumbar isthmic spondylolisthesis (DLIS) and to present the associated clinical results. From March 2022 and April 2023, 25 patients were diagnosed with single-level stable DLIS with RLP and underwent PTELF. Clinical assessments utilized the visual analog scale (VAS), Oswestry Disability Index (ODI), and modified MacNab criteria. All endoscopic surgery videos were reviewed to interpret the pathology associated with DLIS. The mean age of the cohort was 65.3 ± 11.0 years. The mean preoperative ODI score, VAS score for low back, and VAS score of the leg were 64.1 ± 8.2, 7.0 ± 0.7, and 7.3 ± 0.8, respectively. These scores significantly improved to 16.3 ± 10.4, 2.0 ± 0.6, and 1.7 ± 1.0 at the final follow-up, respectively (P<0.01). The modified MacNab criteria indicated "good" or "excellent" outcomes in 92.0% of cases. Analysis of 23 surgical videos revealed 15 patients with disc herniation, nine with lower vertebral endplate involvement, consistent presence of uneven bone spurs (at the proximal lamina stump and around the foramen), and accumulated scars. Two patients experienced postoperative dysesthesia, and one encountered a recurrence of RLP. PTELF emerges as a potentially safe and effective procedure for alleviating RLP in patients with stable DLIS. However, additional evidence and extended follow-up periods are imperative to evaluate the feasibility and potential risks associated with PTELF.

Further characterization of ARSK-related mucopolysaccharidosis type 10.

Mucopolysaccharidosis type 10 is caused by biallelic variants in ARSK, which encodes for a lysosomal sulfatase. To date, seven patients with a mild phenotype resembling spondyloepiphyseal dysplasia or multiple epiphyseal dysplasia have been described. In this report, we present two novel ARSK variants and report clinical and radiological findings of three patients. The patients' initial complaints were hip or knee pain and a waddling gait. All patients showed normal intelligence, normal hearing and eye examinations, and none had organomegaly. While typical dysostosis multiplex findings were not observed, mild platyspondyly with anterior beaking of some vertebral bodies, irregular vertebral endplates, wide ribs, inferior tapering of the ilea with a poorly developed acetabulum, irregularity of the central part of the femoral head, delayed ossification of the carpals were noted. Remarkably, all patients showed metaphyseal striation of the long bones, a crucial diagnostic clue to identify ARSK-related MPS type 10. Interestingly, vertebral involvement regressed during follow-up. On the other hand, hip dysplasia progressed in all patients. In conclusion, this study provides valuable long-term results on a recently discovered form of MPS.

Extrarenal nephroblastomas in the inguinal region and paraspinal musculature with vertebral involvement and spinal cord compression in a 12‐year‐old dog

AbstractA 12‐year‐old, entire, male shar‐pei was presented with a 1‐month history of depression, lumbar pain and progressive hindlimb weakness. In addition, the owners had noticed a mass in the right inguinal region. Computed tomography showed a contrast‐enhanced soft tissue mass located at the right paraspinal musculature, affecting the vertebral body of T13, invading the vertebral canal and compressing the spinal cord. The inguinal mass showed similar imaging characteristics. Due to the uncertain prognosis, euthanasia was recommended, and postmortem examination was requested. Microscopic and immunohistochemical findings were consistent with ectopic nephroblastomas. According to this case report, ectopic nephroblastomas should be considered within the differential diagnosis of masses affecting the paraspinal musculature, as well as the inguinal region, even in senior dogs. To the authors’ knowledge, this is the first report of two ectopic nephroblastomas presented in different locations in a dog.

Spinal lymphoma in a goat.

A 3-year-old Pygmy Wether was presented for chronic hindlimb paralysis. A neurological exam revealed nonambulatory paraplegia with absent deep pain nociception, lack of hindlimb withdrawal reflexes, and paraspinal pain on palpation with T3 to L3 neurolocalization. MRI of the lumbar spine revealed an extensive, dorsal to dorsolateral, severely compressive, heterogeneously contrast-enhancing extradural lesion of the lumbar spine with intervertebral foraminal extension into the surrounding paraspinal musculature. Vertebral bone marrow involvement was also noted in the L5 and L6 vertebrae. A diagnosis of lymphoma was obtained after cytological sampling. This is the first case report describing specific MRI findings (signal characteristics, enhancement pattern, and perilesional changes) in a goat with paraspinal lymphoma.

Single Sequence Whole-Spine Screening Magnetic Resonance Imaging: Diagnostic and Therapeutic Role in Multiple-Level Spinal Tuberculosis.

Spinal tuberculosis (TB) is the most common form of skeletal tuberculosis. Paradiscal continuous vertebral involvement at a single level is the most prevalent pattern among all forms of spinal TB. There is a wide range of reported incidences of multiple-level non-contiguous spinal TB in the literature. We would like to discuss on the utility of single whole spine screening T2-weighted (T2W) mid-sagittal magnetic resonance imaging (MRI) film in diagnosing multiple-level spinal TB and therapeutic benefits it can provide. We have done a retrospective review of the collected data of patients in Vardhman Mahavir Medical College and Safdarjung Hospital from August 2017 to October 2021 to find the incidence of multiple-level spinal TB and possible factors attributed to this specific disease pattern. All the patients who had been diagnosed of spinal TB either microbiologically or histopathologically or by a good clinical response to anti-tubercular treatment (ATT) and had a whole spine screening MRI film, were included. Patients of spinal TB who did not have a whole spine screening MRI were excluded from the study. Multiple-level spinal TB was diagnosed when lesions were identified in vertebral levels other than a typical paradiscal lesion, and additional lesions were separated from the primary disease by at least one normal spinal segment. Among the patients, 242 met the inclusion criteria, and 76 showed multiple-level non-contiguous spinal TB on MRI, incidence being 31.4%. The rest of the 166 patients showed typical single-segment contiguous lesions. By doing multivariate analysis to determine the independent risk factors for multiple-level spinal TB, extremes of age (<20 years and >50 years) have been found to be a significant factor with p value of 0.0001. Though drug resistance was not found to be a significant risk factor (p value 0.051), the proportion of patients having multiple-level TB was far more in the drug-resistant group (13/76). Single sequence whole spine screening MRI film is an effective, economical, and time-saving tool to detect multiple-level spinal TB. Along with its diagnostic accuracy, it also provides therapeutic benefits like access to a more approachable site for biopsy.

Transfacetal and transpedicular anterior decompression with posterior stablilization: Effective way for managing all cases of andersson lesion

Abstract Background: Andersson lesion (AL), also known as aseptic spondylodiscitis, is a pathological condition characterized by a destructive lesion in the vertebral or discovertebral region. The aim of this study was to assess functional, radiological, and neurological outcome of midline posterior surgery with transfacetal/transpedicular decompression and long-segment instrumentation and fusion in all patients with AL. Materials and Methods: A total of 36 consecutive patients with AL with or without neurodeficit were managed with midline posterior approach with long-segment fixation, decompression and anterior vertebral reconstruction added by same midline approach. The demographic data, visual analogue scale (VAS), modified Oswestry Disability Index (mODI), ankylosing spondylitis quality of life (ASQoL), local and global kyphosis angle, Frankel neurological grade, blood loss, duration of surgery, perioperative complications, and fusion rate were compiled and assessed. Results: The mean age of the patients was 52 years (26 males and 10 females). Among the patients, 9 patients had thoracic, 25 patients had thoracolumbar, and 2 patients had lumbar vertebral involvement. All patients in the study achieved fusion at final follow-up period of 24 months. The mean duration of hospital stay, intraoperative blood loss, and surgery duration was 6.17 days, 252 mL, and 130 min, respectively. VAS improved from mean 7.69 ± 0.98 to 1.67 ± 0.72, mODI from mean 70.28 ± 3.55 to 21.14 ± 2.13, ASQoL from mean 14.22 ± 1.59 to 7.17 ± 1.25, local kyphosis from 23.61 ± 1.67 to 18.52 ± 1.05, and global kyphosis from 57.02 ± 0.72 to 36.16 ± 1.23, leading to better sagittal balance. Except two patients all had full neurological recovery. Conclusions: Posterior midline approach with long-segment instrumentation and anterior decompression by transpedicular/transfacetal approach and bone grafting with selective use of cages can give satisfactory results with excellent fusion rates and good functional outcomes.

Evaluation of the role of computed tomography guided biopsy in effective diagnosis and management of patients with Koch’s spine in India

Background: In the Indian population, tuberculosis and malignancy are the most common spinal pathologies. Radiological findings are often non-specific, thus non-diagnostic and fail to provide a prognostic perspective if the disease is established. Therefore, bacterial and/or histological evidence must be obtained to distinguish one infection from another or neoplasm. In this study, we evaluated the role of Computed Tomography-guided biopsy in Koch's spine by assessing diagnostic yield, the incidence of patients with drug-resistant tuberculosis, and drug sensitivity. Methods: Patients with suspected Koch's spine attending outpatient department of tertiary health care centre in India were selected for the study. Data were collected using proforma containing demographic, clinical, radiological and other laboratory variables. In addition, biopsy samples were sent for microbiological and histopathological analysis. Patients were followed up at an interval of 3 months to one year. Results: Most patients had Lumbar vertebra involvement followed by dorsal and least with cervical spine.41.25% of cases were drug resistant. In resistant cases, Isoniazid resistance is more seen, followed by Rifampicin. The clinical assessment revealed a significant difference in fever, back pain, Weight WBC count, Erythrocyte Sedimentation Rate and C Reactive Protein post-biopsy and treatment. Conclusions: Patients with Koch's spine should have tissue sampling for diagnosis and drug sensitivity; otherwise, they will not receive adequate treatment, leading to delayed recovery, disease worsening and resistance. Computed tomography guided biopsy thus helps early diagnosis and guides to proper anti-tuberculous treatment. In addition, it helps to decrease the burden of morbidity associated with Koch's spine.

Clinical characteristics and predictors for recurrence in chronic nonbacterial osteomyelitis: a retrospective multicenter analysis.

Chronic nonbacterial osteomyelitis (CNO) is a rare disease of unknown etiology and most commonly occurs during childhood or adolescence. The purpose of this study is to collect data on the clinical features, outcomes, and management of the disease and to identify the factors affecting recurrence. This is a retrospective multicenter cross-sectional study of pediatric patients diagnosed with CNO. A total of 87 patients with a diagnosis of CNO followed for at least 6 months in 8 pediatric rheumatology centers across the country between January 2010 and December 2021 were included in this study. The study included 87 patients (38 girls, 49 boys; median age: 12.5 years). The median follow-up time was 20 months (IQR: 8.5-40). The median time of diagnostic delay was 9.9 months (IQR: 3-24). Arthralgia and bone pain were the most common presenting symptoms. Multifocal involvement was detected in 86.2% of the cases and a recurrent course was reported in one-third of those included in the study. The most commonly involved bones were the femur and tibia. Vertebrae and clavicles were affected in 19.5% and 20.6% of cases, respectively. The erythrocyte sedimentation rate (ESR) values of 60.9% of the patients were above 20 mm/h and the C-reactive protein values of 44.8% were above 5 mg/L. The remission rate was 13.3% in patients using nonsteroidal antiinflammatory drugs and 75.0% in those using biological drugs. Vertebral and mandibular involvement and high ESR values at the time of diagnosis were associated with recurrence. In this multicenter study, CNO with vertebral and mandibular involvement and high ESR at diagnosis were associated with recurrence.

An Interesting Case Report on Calcaneal Tuberculosis as a Rare Presentation of Disseminated Tuberculosis

Despite the high prevalence rate of tuberculosis infection in Malaysia, calcaneal tuberculosis (TB) is rare. In this article, we present a case of a 53-year-old Malay female who initially presented with left calcaneal swelling for 3 months. Surgical drainage was performed and affected calcaneal was biopsied for histological examination which findings reported as consistent with tuberculosis infection. Further history revealed concomitant respiratory symptoms with the diagnosis of disseminated TB is supported by positive Mantoux test, detection of Acid-Fast bacilli in sputum and CT imaging showing lung and vertebral involvement. Anti-tuberculosis medication is the first line of treatment in calcaneal TB and surgery is usually reserved for patient with severe, intractable disease.
