Mycotic aneurysms are a rare but potentially life-threatening complication of infections, particularly those involving the spine. Spondylodiscitis, a bacterial or fungal infection of the intervertebral disc, is a known risk factor for the development of mycotic aneurysms. Early diagnosis and prompt treatment are crucial for improving patient outcomes. We report the case of a 79-year-old patient with a history of diabetes admitted for chronic back pain refractory to medical treatment. A cervico-thoraco-abdomino-pelvic CT scan showed infectious spondylodiscitis at the lumbar level complicated by a mycotic aneurysm of the infrarenal abdominal aorta. This case highlights the diagnostic challenges associated with mycotic aneurysms, particularly when they arise from a contiguous infectious focus. Imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), play a pivotal role in identifying these aneurysms and assessing their extent.The patient underwent surgical management of the spondylodiscitis and the mycotic aneurysm. A stent was placed to reinforce the weakened aortic wall and prevent rupture. Postoperative management included long-term antibiotic therapy to eradicate the infection. The patient experienced a favorable outcome, with resolution of symptoms and improved quality of life.

Tuberculosis Spondylitis, also known as Pott's Disease, is an extrapulmonary form of tuberculosis (TB) that affects the spine. Sternal involvement is rare and accounts for only 0.3 % of cases. Its presentation is usually insidious in onset with many patients having little to no symptoms. Additionally, microbiological and histological results are inconsistent due to paucibacillary load from vertebral biopsies making definitive diagnosis challenging. Due to difficulty obtaining a diagnostic sample, a significant amount of TB spondylitis cases are presumed TB cases from improving clinical symptoms after empiric treatment as was our case. The purpose of this case report is to emphasize the diagnostic challenges of TB as well as present imaging findings over the course of two years with progressive involvement of the spine and sternum. Thus, here we report a case of presumed spinal tuberculosis affecting not only multiple levels of the spinal column but also the sternum in an immunocompetent United States born citizen with an indolent clinical course.

Gout is a crystalline arthropathy associated with prolonged body overload with uric acid. The most common sites are the distal joints of the lower limbs and the spine is rare. We report a case of gout with an initial cervical location of spondylodiscitis with epiduritis in a 62-year-old patient.

Background: Surgical treatment of spinal infections, refractory to medical treatments, is increasing in incidence. Here, we present a unique case of discitis secondary to an iatrogenic cause, spinal steroid injection, that resulted in acute neurology, ventral phlegmon, and osteomyelitis requiring multiple surgical interventions for treatment. Case Description: With the adoption of minimally invasive spinal surgery, the patient underwent full endoscopic debridement and decompression at our hospital. The endoscopic technique offers a unique avenue to the anatomically difficult ventral phlegmon for surgical excision, cultures, and pathogen identification. The endoscopic debridement was paired with percutaneous pedicle screw fixation to stabilize the spine from the worsening bone destruction. Outcome: The patient recovered well postoperatively, with the resolution of her neurological symptoms and improved mobility. Conclusions: Full endoscopic spinal debridement and decompression is a powerful tool to manage severe spinal discitis and preliminary studies encourage its adoption in surgical practices.

Co-infection with Brucella melitensis and Coxiella burnetii has been rarely reported. To date, there are only two co-infection case reports from Croatia and China which diagnosed the infections mainly through the use of serological tests. In this report, we present the first case of molecularly confirmed B. melitensis bacteremia and C. burnetii spondylodiscitis co-infection in a goat dairy farmer who presented with lumbosacral spondylodiscitis and bilateral psoas abscesses. From the blood culture, B. melitensis was identified by using 16S rRNA gene sequencing and specific PCR. Lumbar bone tissue was found to be positive for C. burnetii using multiplex real-time PCR and was confirmed with a positive result from conventional PCR which detected the infection through the identification of the IS1111 gene. The patient's condition improved after decompressive laminectomy was performed and administration of antibiotics regimen: intravenous gentamicin, oral rifampicin, and oral doxycycline. From our case, it is important to raise awareness of this underreported co-infection with multiple zoonotic diseases, especially Q fever and brucellosis, which share the same exposure risk. Moreover, we also emphasize the use of advanced molecular techniques to improve the diagnostic efficiency and reduce the use of time-consuming procedures among patients who are continuously exposed to such risk factors in areas with high seroprevalence of these zoonotic diseases.

Pott's disease or tuberculous spondylodiscitis is the disco-vertebral localization of Koch's bacillus. It causes progressive spinal lesions, with abscesses forming in the perivertebral soft tissues and epidural spaces. Medical imaging plays an indisputable role in the diagnosis and management of Pott's disease. Magnetic resonance imaging (MRI) enables early positive diagnosis and assessment of spinal damage. Computed tomography (CT) is currently the best interventional imaging method for the drainage of soft tissue abscesses and disco-vertebral biopsies for bacteriological and histological purposes. We report a case of accidental discovery of Pott's disease with abscesses of the psoas simulating an appendicular syndrome and describe its epidemiological, clinical, and radiological aspects through a review of the literature.

Introduction: Spondylodiscitis (SD) is an infection of the intervertebral disc with involvement of the adjacent vertebral bodies. Diagnostic tests with CT-guided biopsy only provide a positive yield in 14%–48% of cases. Percutaneous endoscopic debridement and drainage (PEDD) has recently shown promise in the treatment of spondylodiscitis. Research question: The purpose of this study is to determine differences in pathogen identification and clinical outcomes for PEDD versus CT-guided needle biopsy in SD patients. Materials and methods: We conducted a systematic review of the literature using PRISMA guidelines to determine differences in positive microbiology results, perioperative complications, pain control, and long-term clinical outcomes for PEDD vs. CT-guided needle biopsy in SD patients. Results: 1078 studies were evaluated, 87 of which underwent full review. 15 studies met the inclusion and exclusion criteria, including 7 PEDD, 7 CT-guided biopsy, and 1 CT-guided biopsy vs. PEDD article, for a total of 192 PEDD patients and 604 CT-guided biopsy patients. We found 36.59% of CT-guided biopsy patients had positive microbiology results, compared to 84.38% of PEDD patients. No major perioperative complications occurred as a result of the PEDD procedure. Of the five PEDD studies that reported pain outcomes, greater than 80% of patients experienced relief after intervention. Discussion and conclusion: These results suggest that PEDD may improve pathogen identification while simultaneously reducing pain compared to CT-guided needle biopsy in SD. Although current treatment guidelines recommend CT-guided biopsy, in patients with severe back pain and suspected SD, PEDD can be considered an alternative intervention.

Achromobacter xylosoxidans is a Gram-negative, aerobic, non-fermenting bacillus mainly responsible for nosocomial infections. We report the first case of community-acquired spondylodiscitis caused by Achromobacter xylosoxidans in a 61-year-old woman, immunocompromised with necrotizing dermohypodermitis of the right lower limb successfully treated with ertapenem and ciprofloxacin.

Campylobacter sp. is widely considered a leading causative agent of bacterial food-borne gastrointestinal illness. Discitis and endocarditis caused by Campylobacter spp. are extremely rare. We describe the case of a 94-year-old man who was admitted for recent lumbar pain, diarrhea, and fever. C. fetus and C. coli were identified by MALDI-TOF from blood and stool samples respectively. MRI of the spine showed L5–S1 discitis. Patient was treated with 6 weeks of amoxicillin with clinical and microbiological response until cardiac implantable electronic device (CIED) related endocarditis occurred four weeks after the end of the antibiotic treatment. He was treated with another 6 weeks amoxicillin regimen, with a favorable outcome after a 6-month follow-up. Enteric infection with Campylobacter spp. in a debilitated patient should raise the possibility of a co-infection with another more invasive species such as C. fetus, leading to systemic invasion. In case of Campylobacter fetus bacteremia, a search for endocarditis and spondylodiscitis is recommended even in the absence of specific clinical signs.

The presented case report concerns a 40-years-old man who was admitted to the infectiology department for back pain and elevated C-reactive protein, leading to suspicion of spondylodiscitis. Initially, the first lumbar spine MRI yielded negative results. Nevertheless, the patient was treated with Gentamicin followed by Ceftriaxone and Levofloxacin for a sepsis to Shewanella Algae. The second lumbar spine MRI on day 8 confirmed the diagnosis.

Background: Generally, a sufficient duration of relevant antibiotics based on an appropriate culture combined with proper surgical treatment guarantees a favorable clinical outcome in patients with pyogenic spine infections. However, a patient’s condition often deteriorates as concurrent infections occur in other organs, leading to mortality. Therefore, this study aimed to investigate the epidemiology of concurrent infections in patients with a pyogenic spine infection and estimate the rates and risks of early mortality. Methods: Patients with a pyogenic spine infection were identified using a national claims database that includes the entire population. The epidemiology of the six types of concurrent infections was investigated, and the corresponding early mortality rates and risks were estimated. The results were validated internally by bootstrapping and externally by defining two additional cohorts for sensitivity analysis. Results: Among 10,695 patients with a pyogenic spine infection, the prevalence of the six types of concurrent infections was 11.3 % for urinary tract infections, 9.4 % for intra-abdominal infections, 8.5 % for pneumonia, 4.6 % for septic arthritis or osteomyelitis of the extremities, 0.7 % for central nervous system infections, and 0.5 % for cardiac infections. Patients with a concurrent infection had approximately 4-fold greater mortality than those without (3.3 % vs. 0.8 %). The early mortality rates were particularly higher in patients with multiple or specific types of concurrent infections, including central nervous system infections, cardiac infections, and pneumonia. In addition, the mortality trends differed significantly according to the number and type of concurrent infections. Conclusions: These data on six types of concurrent infection among patients with pyogenic spinal infection can be used as a source of reference by clinicians.

The successful operative management of spinal infections necessitates a thoughtful approach. Ideal treatment combines the universal goals of any spine operation, which are decompression of the neural elements and stabilization of instability, with source control and eradication of infection. Techniques to treat infection have evolved independently and alongside advances in implant technology and surgical techniques. This review will seek to outline current thinking on approaches to both primary and secondary spinal infections.

Background: Spinal tuberculosis (TB) is the most common extrapulmonary form of tuberculosis. In both developing and developed countries, TB has been on the rising trend due to factors such as increasing HIV coinfection, multidrug resistance of the organism, and global migration. Spinal TB, which most often affects the lower thoracic and thoracolumbar area, accounts for 50% of all musculoskeletal tuberculosis. Methods: Using the Cochrane Database of Systematic Reviews, EMBASE, and PubMed, a systematic computerized literature search was performed. Analyses of studies published within the past 10 years were conducted. The searches were performed using Medical Subject Headings terms, with “spinal tuberculosis,” “diagnosis,” “epidemiology,” and “etiology”,“management,” “surgery,” and “therapy” as subheadings. Results: Progressive collapse, kyphosis, and neurological deficiency are hallmarks of the disease because of its destructive effect on the intervertebral disc and adjacent vertebral bodies. The condition may be identified using laboratory testing and distinctive imaging features, but the gold standard for diagnosis is tissue diagnosis using cultures, histology, and polymerase chain reaction. Uncomplicated spinal TB is today a medical condition that can be adequately treated by multidrug ambulatory chemotherapy. Surgery is reserved for individuals who have instability, neurological impairment, and deformity correction. Debridement, deformity correction, and stable fusion are the cornerstones of surgical treatment. Conclusions: Clinical results for the treatment of spinal TB are generally satisfactory when the disease is identified and treated early. However, the major health issue and the biggest obstacle in achieving the goals of the “End TB strategy” is the recent rise in the emergence of drug resistance. Hence strict vigilance and patient perseverance in the completion of the treatment is the main need of the hour.

ABSTRACT: Background: The diagnosis of spinal tuberculosis often relies on clinical, radiological, and laboratory findings, particularly in resource-constrained settings. However, numerous noninfectious conditions exhibit similar clinical and radiological features to spinal tuberculosis, leading to potential misdiagnosis in the absence of microbiological or histopathological confirmation. This study aims to present a case series from a developing country, highlighting noninfectious conditions that mimic spinal tuberculosis. Methods: A retrospective analysis was conducted on hospital records and imaging of patients diagnosed with spinal tuberculosis, lacking microbiological or histopathological evidence, and unresponsive to empirical antitubercular treatment. Patients displaying noninfectious conditions resembling spinal tuberculosis upon further investigation were included. Clinical and radiological findings of these patients were thoroughly analyzed. Results: Among a total of 23 patients observed over a 6-year period (2015–2020), various noninfectious conditions were identified as mimickers of spinal tuberculosis. These conditions included vertebral body haemangioma, ankylosing spondylitis (with or without Andersson lesion), rheumatoid pannus, osteoid osteoma, cystic hygroma, multiple myeloma, vertebral metastasis, malignant small round-cell tumor, pancreatic pseudocyst, esophageal duplication cyst, Modic changes in degenerative disc disease, Paget's disease, and psoas hematoma. Conclusion: Noninfectious spinal conditions can masquerade as spinal tuberculosis, underscoring the importance of obtaining a definitive tissue diagnosis before initiating antitubercular treatment. Particular attention should be given to features such as central lesions and the absence of soft tissue involvement in suspected cases of spinal tuberculosis, warranting a careful reconsideration of the diagnosis.

ABSTRACT: Ureaplasma urealyticum is part of the normal genital flora of many sexually experienced people, thereby it is mostly associated with genitourinary tract infections. Here, we present the first case reported in the literature of spondylodiscitis caused by U. urealyticum in a 62-year-old immunocompetent subject. U. urealyticum was detected through broad-range bacterial polymerase chain reaction in all samples obtained by T11 bone biopsy, while cultures were all negative. Due to the technical difficulties in removing the spinal osteosynthesis devices, no neurosurgical intervention was planned, therefore a suppressive therapy with moxifloxacin was administered. After 7 months, the patient underwent T10-11 partial vertebrectomy, insertion of an expandable cage at that level, the substitution of T11 screws, and prolongation of stabilization from T6 to ilium due to a fracture of T11 and T12; the remaining spinal osteosynthesis material was not removed. A computed tomography scan of the spine did not show features compatible with spondylodiscitis. Moxifloxacin was stopped after 15 months without any recurrence of U. urealyticum infection. Our case highlights the importance of considering U. urealyticum as a potential etiological germ in culture-negative spondylodiscitis.

Introduction: The myriad presentation of osteoarticular brucellosis make the patient seek the help of general practitioners, orthopaedic and rheumatology specialists. Moreover, the lack of disease-specific symptomatology is the leading cause of the delay in diagnosing osteoarticular brucellosis. Given the increasing number of spinal brucellosis cases across the country, no literature is presented on the systematic management of spinal brucellosis. However, with our experience, we formulated a classification for managing spinal brucellosis. Methods: A single-centred prospective observational study was conducted with 25 confirmed cases of spinal brucellosis. Patients were analysed and graded clinically, serologically, and radiologically and were managed with antibiotics for 10–12 weeks, and if necessary, stabilisation and fusion were done based on the treatment classification devised. All patients were followed up to ensure disease clearance at serial follow-up with relevant investigations. Results: The mean age of the study participants was 52.16 ± 12.53 years. According to spondylodiscitis severity code (SSC) grading, four patients belong to grades 1, 12 to grade 2 and 9 to grade 3 at presentation. Erythrocyte sedimentation rate (p = 0.02), c-reactive protein (p

Resumen: Introducción: La biopsia discal es una herramienta necesaria en el proceso diagnóstico y terapéutico de las espondilodiscitis. Su rentabilidad es variable según condicionantes como la técnica utilizada, el uso concomitante de antibióticos o el germen causante. Estudiamos los resultados de este procedimiento en nuestro centro en un periodo de 5 años. Material y métodos: Análisis retrospectivo de todos los casos que requirieron biopsia discal por posible espondilodiscitis en nuestro centro entre enero de 2015 y noviembre de 2019, tanto percutánea (26 casos) como abierta (13 casos). Recogemos datos de filiación y clínicos, comorbilidad, antibioterapia concomitante, pruebas de imagen, tipo de biopsia, resultado de cultivos y evolución clínica. Resultados: Treinta y nueve pacientes: 66,7% varones, 66,9 años de edad media. El 74% con factores de riesgo conocidos. El síntoma principal es dolor mayoritariamente (89,7%) y fiebre en el 5%. La RMN en la prueba más frecuentemente realizada (87%). Los segmentos lumbares se afectaron en el 76,9%, por el 23% los dorsales. En 9 casos (23%) los pacientes reciben tratamiento antibiótico simultáneamente a la realización de la biopsia. En estos casos la biopsia siempre arrojó un resultado negativo. Los cultivos fueron positivos más frecuentemente en los pacientes sin antibióticos en el momento de la biopsia (53,3%), con significación estadística. Los microorganismos aislados de manera más repetida fueron los bacilos gramnegativos (31,2%) y los cocos grampositivos (31,2%). Constatamos 2 fallecimientos durante el ingreso por sepsis (dentro del primer mes tras el diagnóstico). Del resto de los pacientes fallecieron 5 de manera tardía durante el seguimiento: 3 por nuevas infecciones complicadas de manera tardía y 2 por complicaciones ulteriores de patologías previas. El resto de pacientes con diagnóstico final de espondilodiscitis evolucionaron satisfactoriamente con antibioterapia. Conclusiones: La espondilodiscitis es potencialmente grave y requiere un adecuado diagnóstico, siendo la biopsia discal un procedimiento necesario en ocasiones. Una mala situación clínica del paciente puede imposibilitar la retirada del antibiótico, lo cual disminuye drásticamente el rendimiento de la biopsia. Abstract: Introduction: Spinal disc biopsy is a necessary tool in diagnosing and treating spondylodiscitis. Its profitability varies according to the technique, concomitant antibiotics therapy or causative germ. We studied the results of this procedure in our institution. Materials and methods: Retrospective analysis of all cases requiring disc biopsy due to possible spondylodiscitis over a 5 year period, both percutaneous (26 cases) and open (13 cases). We collected filiation and clinical data, comorbidity, concomitant antibiotic therapy, imaging tests, biopsy type, cultures results and clinical evolution. Results: 39 patients; 66.7% male, 66.9 years of average age. 74% has known risk factors. The main symptom was pain (89.7%). Fever occurred in 5%. MRI performed in 87%. Lumbar involvement in 76.9%. 9 patients (23%) received antibiotic treatment simultaneously with biopsy. In these cases biopsy always yielded a negative result, but positive in patients without antibiotics at the time of the biopsy (53.3%), with statistical significance. Most frequent isolated microorganisms were gram-negative bacilli (31.2%) and gram-positive cocci (31.2%). We found 2 deaths during admission for sepsis (within the first month after diagnosis). Of the rest of patients, 5 died late during the follow-up: 3 due to new infections and 2 due to subsequent complications of previous pathologies. The remaining patients with final diagnosis of spondylodiscitis evolved satisfactorily with antibiotic therapy. Conclusions: Spondylodiscitis is potentially serious and requires an adequate diagnosis, with disc biopsy being a necessary procedure on occasions. Patients poor clinical condition can make it impossible to withdraw antibiotics, which drastically reduces the performance of the biopsy.

Spinal tuberculosis (Pott's disease) is a frequent manifestation of Mycobacterium tuberculosis infection. It manifests as destruction of 2 or more adjacent vertebral bodies followed with destruction of the intervertebral disc, leading to a condition known as spondylodiscitis. Tuberculous spondylodiscitis represents with back pain, fever, joint stiffness, loss of spinal mobility, neurological symptoms, vertebral body collapse, gibbus formation and kyphosis. Persistent Pott's disease might lead to soft tissues abscesses, frequently involving iliopsoas muscle.We, herein, present a 20 years long follow-up case of a Pott's disease patient. The patient got diagnosed as tuberculous spondylodiscitis, almost 10 years after first symptoms onset. She underwent frequent computed tomography and magnetic resonance scanning, with spinal spondylodiscitis being its only significant finding, while lung parenchyma and other organs were not infected. Patient got treated with multidrug anti-tubercular regimen for 18 months in 2 different periods of time; nonetheless she complicated with iliopsoas muscle abscess and percutaneous fistula.Early diagnosis and treatment of spinal tuberculosis (TB) are of great importance in ensuring a good clinical outcome. Delaying the diagnosis and proper management can lead to spinal cord compression, deformity and irreversible neurological complications. Thus, multidrug anti-tubercular therapy must be started timely and the duration of anti-tubercular therapy needs to be individualized. The decision to terminate anti-tubercular therapy should be based on clinical, radiological, pathological and microbiological indices, rather than being based on specific guidelines.

Parvimonas micra is an obligate anaerobe that forms part of the normal gastrointestinal flora. The advent of matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF) and 16s ribosomal RNA gene sequencing has led to increased detection of many rare anaerobic isolates, including Parvimonas micra. Typical risk factors for Parvimonas micra bacteremia include dental procedures or spinal instrumentation. Here, we report a case of Parvimonas micra spondylodiscitis and psoas abscess in a patient with no obvious antecedent risk factors and explore the challenges in isolation of the organism from tissue samples.

Introduction: Meningitis is a rare but severe complication in patients with spondylodiscitis. Data about the incidence and clinical management are rare. Research question: Aim of this study was to assess the incidence, clinical course and outcome of patients suffering from meningitis due to spondylodiscitis. Material and methods: We performed a retrospective analysis of our prospective clinical database that included all patients suffering from spondylodiscitis between January 2010 and December 2019 were included. We assessed clinical findings, laboratory tests, treatment and outcome comparing patients with and without meningitis. Results: Out of 469 patients suffering from spondylodiscitis, 30 patients (14 female) were diagnosed with an associated meningitis (6.4%). The mean CSF cell count was 3375.85 ± 8486.78/μl (range 32-41500/μl). The mean age at presentation was 70.87 ± 8.84 yrs (range 48-88 yrs). Mean C-reactive protein (CRP) and white blood cell (WBC) counts at time of admission were statistically higher in patients with associated meningitis (CRP: 19.81 ± 12.56 mg/dl vs. 11.63 ± 11.08 mg/dl, p = 0.001; WBC: 14.67 ± 7.76 g/l vs. 10.88 ± 05.11 g/l, p = 0.005. Mortality was also higher, as 13.3% and 7.1% of patients with and without concomitant meningitis died, respectively. Conclusion: Bacterial meningitis due to spondylodiscitis is a rare but severe condition and is associated with higher morbidity and mortality rates. In patients with spondylodiscitis presenting with an altered state of consciousness an associated meningitis should be ruled out.

Background: Spondylodiscitis is a potentially life-threatening infection of the intervertebral disk and adjacent vertebral bodies, with a mortality rate of 2–20%. Given the aging population, the increase in immunosuppression, and intravenous drug use in England, the incidence of spondylodiscitis is postulated to be increasing; however, the exact epidemiological trend in England remains unknown. Objective: The Hospital Episode Statistics (HES) database contains details of all secondary care admissions across NHS hospitals in England. This study aimed to use HES data to characterise the annual activity and longitudinal change of spondylodiscitis in England. Methods: The HES database was interrogated for all cases of spondylodiscitis between 2012 and 2019. Data for the length of stay, waiting time, age-stratified admissions, and ‘Finished Consultant Episodes’ (FCEs), which correspond to a patient's hospital care under a lead clinician, were analysed. Results: In total, 43135 FCEs for spondylodiscitis were identified between 2012 and 2022, of which 97.1% were adults. Overall admissions for spondylodiscitis have risen from 3 per 100,000 population in 2012/13 to 4.4 per 100,000 population in 2020/21. Similarly, FCEs have increased from 5.8 to 10.3 per 100,000 population, in 2012–2013 and 2020/21 respectively. The highest increase in admissions from 2012 to 2021 was recorded for those aged 70–74 (117% increase) and aged 75-59 (133% increase), among those of working age for those aged 60–64 years (91% increase). Conclusion: Population-adjusted admissions for spondylodiscitis in England have risen by 44% between 2012 and 2021. Healthcare policymakers and providers must acknowledge the increasing burden of spondylodiscitis and make spondylodiscitis a research priority.

Objectives: This project is an application of the One Paleopathology approach to the study of Q fever (C. burnetii infection), a disease which is underdiagnosed and largely unknown in paleopathology., Materials: Clinical and veterinary pathological case reports and reviews, bioarcheological and zooarchaeological data, veterinary and environmental studies of wild and domestic animal pathology, clinical molecular pathogen data METHODS: One Paleopathology approach which combines data from people, animals, and their environment to understand disease in the past., Results: Q fever in animals presents as reproductive failure, with no typical skeletal manifestations seen in animals. Persistent Q fever (C. burnetii) focalized infection affects the human skeleton in predictable ways, including spondylodiscitis and extravertebral osteomyelitis or osteitis which can occur more commonly in children. Evidence of skeletal involvement suggests C. burnetii infection in the past is underestimated and underdiagnosed in humans., Conclusion: Using the One Paleopathology approach can improve the study of C. burnetii infection in the past, where both animal and human paleopathology and environmental factors are assessed in developing potential diagnoses., Significance: This project is the first paleopathological study to specifically focus awareness on identification of C. burnetii in past skeletal samples, both animal and human., Limitations: Lack of paleopathological studies and existing reference literature identifying skeletal involvement associated with C. burnetii infection., Suggestions for Future Research: Future paleopathological genomic studies should focus on identification of C. burnetii genotypes., Competing Interests: Declaration of Competing Interest None., (Copyright © 2024 Elsevier Inc.

We present a case of spondylodiscitis caused by Aspergillus fumigatus, which we successfully treated with isavuconazole after voriconazole severe intolerance. Aspergillus spondylodiscitis is a severe and relatively rare form of extra-pulmonary invasive aspergillosis. Typically, voriconazole is the first-choice antifungal drug for treating Aspergillus osteomyelitis or spondylodiscitis. However, isavuconazole, a new antifungal medication, has been demonstrated as non-inferior to voriconazole in cases of invasive aspergillosis. It has the added benefits of fewer hepatobiliary, ocular, and cutaneous side effects. It generally does not demand serum level monitoring and poses fewer risks of drug interactions. Nonetheless, there are no studies yet that support its use in spondylodiscitis, and published experiences are very limited and based on isolated cases, albeit mainly positive. The case we present here aims to provide additional evidence on the efficacy and tolerability of isavuconazole in treating this condition., Competing Interests: Declaration of competing interest JF was an advisor/consultant and received grant support and honoraria for talks on behalf of Astellas Pharma, Gilead Sciences, Merck Sharp & Dohme, Shionogi, Mundipharma and Pfizer., (Copyright © 2024 Japanese Society of Chemotherapy, Japanese Association for Infectious Diseases, and Japanese Society for Infection Prevention and Control.

Tuberculosis Spondylitis, also known as Pott's Disease, is an extrapulmonary form of tuberculosis (TB) that affects the spine. Sternal involvement is rare and accounts for only 0.3 % of cases. Its presentation is usually insidious in onset with many patients having little to no symptoms. Additionally, microbiological and histological results are inconsistent due to paucibacillary load from vertebral biopsies making definitive diagnosis challenging. Due to difficulty obtaining a diagnostic sample, a significant amount of TB spondylitis cases are presumed TB cases from improving clinical symptoms after empiric treatment as was our case. The purpose of this case report is to emphasize the diagnostic challenges of TB as well as present imaging findings over the course of two years with progressive involvement of the spine and sternum. Thus, here we report a case of presumed spinal tuberculosis affecting not only multiple levels of the spinal column but also the sternum in an immunocompetent United States born citizen with an indolent clinical course., (© 2024 The Authors.)

Background: The relationship of spinopelvic parameters with spondylolisthesis is widely explored. However, there is scarce evidence on correlation of tuberculosis of lumbar spine with respect to spinopelvic harmony. The current study aims to find the association between functional outcomes and spinopelvic parameters in lumbar spine tuberculosis treatment., Methods: A total of 47 patients with active tuberculosis confined to lumbar spine were prospectively analyzed and divided into 2 groups according to mode of intervention. Group A included 26 operatively managed patients and group B had 21 conservatively managed cases. Functional parameters comprising Oswestry Disability Index (ODI) and Visual Analog Scale (VAS) along with spinopelvic radiologic parameters (pelvic incidence [PI], pelvic tilt [PT], sacral slope [SS], lumbar lordosis [LL], PI-LL, sagittal vertical axis) in both groups were analyzed at 0 and 6 months of follow-up., Results: Both the groups showed significant improvement from initial presentation to final follow-up in ODI (Group A: 85.4 ± 12.1-12.3 ± 3.2, P = 0.02; Group B: 82.5 ± 10.06-36.8 ± 11.9, P = 0.04) and VAS (Group A: 8.1 ± 1.2-1.4 ± 0.9, P = 0.02; Group B: 8.5 ± 0.09-3.5 ± 1.1, P = 0.02). Statistically significant (P < 0.05) difference was observed in both functional outcome parameters between the 2 groups at 2-month and 6-month follow-up, compared with nonsignificant difference (P > 0.05) at presentation. Better improvements of spinopelvic parameters of PT, SS, LL, PI-LL were observed in Group A and in both groups the difference of these parameters correlated with differences of functional outcome parameters, though PI showed no correlation., Conclusions: The spinopelvic parameters played significant role in functional outcome. There is better functional outcome when LL is adequately restored. Surgical correction offered betterment of spinopelvic parameters like PT, SS, an sagittal vertical axis, which in turn leads to improvement in functional outcome., (Copyright © 2024 Elsevier Inc.

Introduction: Fever is a cosmopolit zoonosis due to Coxiella burnetii. The diagnosis of chronic Q fever can be really misleading. The growth of this bacterium is difficult and blood cultures are often negatives., Case Presentation: We rapport here the case of a 69-year-old man presenting with an alteration of his general condition and low back pain. He suffered from a well-controlled HIV infection and lower limb arteriopathy treated with a cross-femoral bypass. A computed tomography scan revealed a L3-L4 abscessed spondylodiscitis but multiple blood cultures remained sterile, and the transthoracic echocardiography was normal. PET scan showed a hypermetabolism on L3-L4 vertebrae but also indicated an intense uptake of the cross-femoral bypass. C. burnetii serology was in favour of a chronic Q fever. The management of this chronic Q fever needed a multidisciplinary discussion. Three months after the treatment initiation, C. burnetii serology was reduced by a titer and has stabilized 6months to a year., Conclusion: Chronic Q fever and mostly osteoarticular diseases are difficult to diagnose. We have to evoke the diagnosis of osteoarticular chronic Q fever in case of insidious inflammatory syndrome, negatives blood cultures spondylodiscitis especially when associated to endocarditis or vascular infection, and in case of spondylodiscitis with a granulomatous histology without Mycobacterium tuberculosis. Although there are many complementary tests (PET scanner, PCR), serology remains the cornerstone of diagnosis., (Copyright © 2024 The Author(s). Published by Elsevier Masson SAS..

Objectives: Pyogenic vertebral osteomyelitis (PVO) is associated with a high burden of disease. Our study aimed to describe characteristics at presentation of PVO, the risk of inadequate treatment response (ITR), relapse, and death, and to determine risk factors for ITR. Methods: Patients with an ICD-10 discharge code for PVO and admission to a major Danish university hospital between November 2016 and April 2019 were included. ITR was defined as clinical, microbiological, and/or radiological progression during treatment. Data were collected through review of medical records, and logistic regression was used to determine adjusted odds ratios (aOR). Results: Of 106 patients included, 87% presented with pain in the spine, 97% elevated CRP, 14% severe sepsis, and 13% with a history of previous spinal surgery. 39% were infected with Staphylococcus aureus and 9% with Escherichia coli. 31% responded inadequately to treatment, and risk factors for ITR were previous spinal surgery (aOR 19.29; 95% confidence interval (CI) 2.20–169.08), severe sepsis (aOR 4.59; 95% CI 1.28–15.41), and infection with Escherichia coli (aOR 8.10; 95% CI 1.71–38.45). 13% experienced relapse within the first 2 years, while the 1-year crude mortality was 12%. Conclusion: Staphylococcus aureus is still the main pathogen in PVO patients, and the risks of relapse and mortality remain high. Factors found to be associated with ITR were previous spinal surgery, severe sepsis, and infection with Escherichia coli.

Abstract: Infections that affect the intervertebral discs and vertebrae are known as spondylodiscitis. Such infections are commonly caused by pyogenic organisms, particularly Staphylococcus aureus, and hematogenous spread is the most common route. Non-pyogenic infections include Mycobacterium tuberculosis and Brucellosis. Mycotic infections are becoming more common, in line with the growing number of immunodeficiency disorders. Cryptococcus is included among these mycotic infections. We present a case of such an infection in a non-immunocompromised patient with a known history of treatment with antitubercular therapy. A 52-year-old man came to our hospital with a backache of one-month duration and progressive neurological deficits of the lower limbs of one-week duration. His imaging studies were suggestive of spondylodiscitis at the D10–11 and D11–12 levels with a left paraspinal abscess. The patient underwent anterolateral decompression, biopsy, and instrumented posterior spinal fusion. The pus grew Cryptococcus, and histopathology confirmed Cryptococcal spondylodiscitis. The patient was treated with parenteral amphotericin B and fluconazole. A mycotic infection must be considered in the differential diagnosis of infectious spondylodiscitis.

Background: A 25-year-old patient was treated for post-traumatic neck pain with intradiscal injections at the C3-4 and C4-5 levels using radiopaque gelified ethanol. After the injections, the axial neck pain increased. Laboratory infection parameters were normal despite the progressive disc destruction observed on CT scans at both index levels. The patient underwent debridement and anterior cervical discectomy and fusion. Staphylococcus epidermidis and Cutibacterium acnes grew in all the intraoperative cultures. The patient was subsequently treated with Rifampicin and Moxifloxacin and after 3 months no signs of infection were observed. CT scan showed solid fusion of the at the index segments 7 months postoperatively. Conclusion: Infections after intradiscal injections are rare and we believe this is the first case describing iatrogenic spondylodiscitis after DiscoGel injection. When increased axial neck pain is experienced after injection with DiscoGel, post-operative spondylodiscitis should be suspected. Even if laboratory parameters are normal, examinations with MRI and CT should be performed and if these studies show signs of infection, surgical revision should be conducted.

Objective: This study presents real-life experience with cefiderocol used on a compassionate basis for treatment of three patients with severe infections caused by extensively/pan-drug resistant (XDR/PDR) Acinetobacter baumannii (Ab). Methods: Serum bactericidal activity was determined and considered as a surrogate of cefiderocol susceptibility. Results: Clinical improvement and microbiological eradication of A. baumannii were observed in all three patients, who were affected by extremely complex conditions either for type of infection, adverse effect or resistance profile of A. baumannii. Conclusion: Cefiderocol for XDR/PDR-Ab infections might be reconsidered, especially in light of the recent disappointing results of the CREDIBLE-CR study.

Objectives: Spondylodiscitis is a severe infection of the spine that can take a diverse number of disease courses depending on its localization, resulting in specific therapeutic strategies. This study aims to identify localization specific characteristics and clinical parameters for spondylodiscitis. Methods: A retrospective review was performed of 211 patients from 2013–2018 with proven spondylodiscitis. In total, 33 were cervical, 48 thoracic and 112 lumbar. In 18 patients disseminated infestations of several localizations were found. The patient records were evaluated for clinical and outcome parameters and demographic characteristics. Results: Patient age, Body Mass Index, inpatient and intensive care stay, and inpatient complications did not differ significantly between different infection localizations. C-reactive protein (CrP) levels showed a significantly reduced value in the thoracic area compared to other localizations. For comorbidities, there was a significantly higher prevalence of endocarditis in disseminated and lumbar infestations compared to thoracic and cervical cases. Epidural abscesses showed a highly increased incidence in cervical cases. With a 30-day mortality rate of 12.1% for cervical, 12.5% thoracic, 13.4% lumbar, and 22.2% in disseminated disease, no significant difference was observed. Conclusions: The present study determined that, although the 30-day mortality rate does not differ according to the localization of the infection, specific clinical parameters, such as CrP values or comorbidities, showed localization-dependent differences.

Introduction: Primary spondylodiscitis due to Listeria monocytogenes (LM) is a rare condition. Research question: We present a case of spontaneous LM spondylodiscitis with an epidural abscess in a middle-aged man, who reported no gastrointestinal infection. Material and methods: We identified 5 spinal infection cases due to LM in the literature, with 3 diagnosed as primary spondylodiscitis. Results: The patient was treated with surgical decompression, debridement, and antibiotic therapy. Blood cultures remained negative throughout the case and microbiological cultures were obtained during surgery. The patient developed side-effects of prolonged gentamicin therapy but made a recovery from his spinal complaints at 6-months follow-up. Listeriosis is a relatively rare food-borne disease with a wide spectrum of presentation. Surgeons should consider more aggressive therapy for spinal infections and recognize the uncommon manifestations. We identified 3 primary and 2 secondary LM spondylodiscitis cases in the literature. Antibacterial treatment of LM spondylodiscitis varied in agents and duration, but no side-effects were previously reported. Gentamicin treatment requires care and attention to complications. Discussion and conclusion: Listeria monocytogenes is a rare cause of primary spondylodiscitis. Further studies are needed to establish a safe treatment protocol for treatment with gentamicin and LM spondylodiscitis.

Introduction: and research question: This paper explains how antibiotic loaded cement can be used in surgical treatment of spondylodiscitis to reconstruct the anterior column of the spine. Material and methods: 35 consecutive surgical procedures performed for spondylodiscitis were collected over a 11-year period and charts were reviewed. Most infections were caused mainly by staphylococcus spp (n = 16), streptococcus spp (n = 8) and pseudomonas spp (n = 4). Most patients had long standing but unsuccessful antibiotic therapy (median 42 days). Other indications included instability, neurologic deficit, abscess, and patients were generally in very poor medical condition. Results: Anterior debridement was followed by a partial cavity filling with surgical high viscosity PMMA cement in all cases. Cement was a high viscosity gentamycin loaded cement, that was placed in the cavity created by debridement under the direct eye control. In 25 cases, a part of the cavity was filled with freeze dried cancellous bone allograft rehydrated in rifampicin. Spine was further stabilized with an anterior plate in 15 cases, with short (+1/+1) posterior instrumentation in 5 cases, and a long (≥ +2/+2) posterior instrumentation in 11 cases. In four patients, spine was left un-instrumented. Immediate, unrestricted mobilization was always authorized after surgery. None of the patients were reoperated neither for mechanical failure nor for infection relapse. Conclusion: This report supports the idea that surgical bone cement is an efficient gap filler when used through anterior approach. For small as well as for large defects, it can help to reconstruct the anterior column and locally control the infection in combination with additional stabilization and optimal intravenous and oral antibiotic treatment.

Non-typhoidal Salmonella (NTS) disease is usually a self-limiting infection presenting with digestive symptoms. However, disseminated presentation with involvement of secondary infectious sites is observed. We report diagnostic specificities and challenges related to the management of three patients with invasive NTS (iNTS) and secondary infectious locations. Among the seven patients (age range 46 – 83 years), four (two with extra-digestive infectious sites) had at least one immune debilitating condition. Two patients were incidentally discovered with iNTS and deceased after developing a septic shock despite antimicrobial treatment. Two individuals recovered under medical treatment without complications. Three other patients presented with secondary infectious sites. Case 1 suffered from urinary tract infection and dorsolumbar spondylodiscitis that responded well to antimicrobials and surgery. Abdominal prosthetic aortic aneurysm was diagnosed in case 2 and medical treatment only was applied. After four years of follow-up, he remains under antimicrobial treatment. Case 3 presented with conjoint thoracic aortic aneurysm and cutaneous abscesses managed with antimicrobials and surgery. Atherosclerosis and previous vascular intervention were the predisposing events for vascular involvement. iNTS is a serious disease carrying a high risk of mortality or secondary locations. Secondary locations can be managed by long duration antimicrobial therapy combined with surgery. Spine and aortitis are the most frequent secondary locations. Multi-drug resistant NTS represent an additional risk of mortality. Public health measures should be implemented to limit the spread of NTS to humans and the emergence of drug resistance.

Spondylodiscitis describes an infection of the vertebral body and disc. Clinical presentation is often nonspecific. As a result, imaging plays a crucial role in establishing the diagnosis. The most common associated organism is Staphylococcus aureus. Actinomyces neuii is a gram-positive rod that is primarily known to cause soft tissue infections but has rarely been described in association with spondylodiscitis. At the time of this publication, only 1 other case of A. neuii has been reported in the literature. We present a case report of a diabetic patient diagnosed with spondylodiscitis with cultures demonstrating A. neuii as the most likely causative organism. In our case, no definitive infectious source was identified. The significance of A. neuii spondylodiscitis is unclear. At 1 year follow up, this patient had been successfully treated with antibiotic therapy, but did suffer from significant chronic back pain attributed to the infection. Finally, our case highlights important clinical and imaging findings that may illustrate the elusive nature of this diagnosis., (Published by Elsevier Inc. on behalf of University of Washington.)

Background: Endoscopic surgery is a minimally invasive procedure that has been shown to relieve intradiscal pressure, irrigation of inflammatory factors, and visual debridement, which are crucial for the successful treatment of spondylodiscitis. This study proposes a systematic review and meta-analysis to evaluate the effectiveness and safety of endoscopic treatment of thoracolumbar spondylodiscitis., Methods: Multiple databases were searched for studies involving thoracolumbar spondylodiscitis treated by endoscopic disc drainage with or without additional posterior fixation over the last 20 years. Studies that met the inclusion criteria, which included outcomes related to the percentage of cured infections, patient satisfaction, regression of inflammatory markers, and/or the percentage of adverse event rates, were included in the analysis. For each study, the percentage of patients who showed improvement or experienced an adverse event was abstracted and pooled in a meta-analysis., Results: Based on the search strategy and inclusion criteria, our systematic review and meta-analysis included 20 studies with 546 participants. The success rate was 89.4% (95% CI 83.1%-94.5%). The rate of major adverse events was 0.3%, while that of postoperative transient paresthesia was 2.6% (95% CI 0.8%-5.1%). The recurrence rate was 1.7% (95% CI 0.3%-4.0%), and revision surgery was 8.5% (95% CI 3.8%-14.6%). The causative pathogen diagnosis rate was 73.9% (95% CI 67.7%-79.8%), while progression of deformity was 3.7% (95% CI 0.2%-9.8%), and spontaneous fusion was 40.1% (95% CI 11.0%-73.3%)., Conclusions: Endoscopic discectomy for thoracolumbar spondylodiscitis has been shown to be a safe technique with satisfactory clinical outcomes and a high causative pathogen identification rate., (Copyright © 2024 Elsevier Inc.

Gout is a crystalline arthropathy associated with prolonged body overload with uric acid. The most common sites are the distal joints of the lower limbs and the spine is rare. We report a case of gout with an initial cervical location of spondylodiscitis with epiduritis in a 62-year-old patient., (© 2024 The Authors.

Objective: Pediatric spondylodiscitis (PSD) is an uncommon condition, for which there are no specific international clinical guidelines. Factors related to complications have not been stablished. Our aim was to describe clinical and epidemiological characteristics of PSD, to analyze factors associated with complications and to evaluate adherence to the recommendations of the Spanish National Consensus Document (NCD) for the diagnostic and therapeutic approach to acute osteoarticular infections., Material and Methods: Ambispective, multicenter, national study of two PSD cohorts: historical (2008-2012) and prospective (2015-2020, after publication of NCD). Patients with diagnosis of PSD were included. Demographic, clinical, microbiological and radiological data were recorded. Factors related to the development of complications were analized by logistic regression. Comparisons between both cohorts were performed., Results: Ninety-eight PSD were included. In 84.7%, diagnosis was confirmed by magnetic resonance imaging. Microbiological isolation was obtained in 6.1%, with methicillin-sensitive S. aureus as the main etiologic agent. Complications occurred in 18.9%, the most frequent being soft tissue abscess. Of the 8.6% of patients with sequelae, persistent pain was the most common. Comparing cohorts, there was better adherence to NCD treatment recommendations in the prospective one (57.6% vs. 12.9%, p < 0.01), including a reduction in the length of intravenous antibiotic therapy (10 vs. 14 days, p < 0.01)., Conclusions: The evolution of PSD in our series was favorable, with low frequency of complications and sequelae. The adherence to the recommendations of the NCD was high. Studies with larger sample size are needed to establish new recommendations to optimize the approach to these infections., (Copyright © 2024 Asociación Española de Pediatría.

Background: Surgical treatment of spinal osteomyelitis and discitis remains challenging due to the risk of implant colonization. We sought to demonstrate the safety and efficacy of using antibiotic-impregnated poly-methyl methacrylate (AI-PMMA) in spinal reconstruction for pyogenic spondylodiscitis. Method: We retrospectively analyzed prospective data on consecutive patients who underwent AI-PMMA interbody fusion for thoracolumbar pyogenic spondylodiscitis from December 2011 to October 2016 at a single institution with multiple surgeons. We included consecutive patients who underwent AI-PMMA spinal reconstruction and fusion and were older than 18 years of age. All patients were included in the analysis regardless of their follow-up status who had previous spine surgery in the same area were excluded. Vancomycin powder was mixed with PMMA and tobramycin. The AIPMMA was introduced into the disc space as 5–10 mm beads, then contoured to fit. The primary outcome was fusion using CT or X-ray. Secondary outcomes were recurrent infection, PMMA-related complications, and VAS results. Descriptive statistics and univariate analyses were used. Results: Sixty-two patients were included in the study. The mean follow-up interval was 18.6 months (3–66 months). Sixty-six AI-PMMA levels demonstrated a fusion rate of 100% (95% CI: 94.9%–100%). There was no cement extravasation or embolism. One patient (1.6%) developed a recurrent infection at the same level requiring revision surgery. Five patients (8%) died on long-term follow-up due to non-PMMA/infection-related causes. VAS back showed significant improvement in pain (7.8 vs. 3.5; 95% CI 2.8–5.8; p = 0.00). Conclusion: We demonstrated that the application of AI-PMMA for spinal reconstruction in pyogenic spondylodiscitis is safe and efficacious. The study is limited by its retrospective design. Prospective studies are warranted.

Background: Coagulase-negative staphylococci (CoNS) are part of the normal skin flora. Although CoNS are generally considered as low pathogenic microorganisms, they can cause serious infections, particularly in the context of foreign body material. Case report: Here we present two cases of concomitant infectious endocarditis and spondylodiscitis; one caused by S. epidermidis, the other by S. haemolyticus. Additionally, we reviewed the literature for previously reported cases of concomitant endocarditis and spondylodiscitis due to CoNS. Conclusion: In patients with back pain and a cardiac device in situ, CoNS should be considered as causative pathogens for possible endocarditis and/or spondylodiscitis, and should not be regarded as contamination.

Bacillus circulans is mainly considered an opportunistic pathogen in immunocompromised patients. However, many different infections have been described in the literature: bacteremia, abscesses, meningitis, endophthalmitis, and wound infections.We observed a spondylodiscitis caused by Bacillus circulans in an immunocompetent patient. To date, this is the first case reported in literature. Vertebral osteomyelitis represents for clinicians a challenging infection to manage and treat, because of its insidious and indolent course. The diagnosis is frequently difficult and can often be delayed for several months and initially be misdiagnosed and mismanaged. For this reason, the clinical case was described and all published cases of infection caused by Bacillus circulans were reviewed.

Pleural effusions are associated with a variety of disease states, rendering the differential diagnosis challenging. Spondylodiscitis is an uncommon disease, and its prompt diagnosis can reduce morbidity and mortality. However, an atypical manifestation of the disease, such as pleural effusion, can result in delayed diagnosis. A 76-year-old woman presented with back pain and right pleural effusion. Magnetic resonance imaging revealed paravertebral soft tissue infiltration, with enhancement of bone marrow and intervertebral disk at the T8 and T9 levels, suggesting spondylodiscitis. In patients with exudative pleural effusion, spondylodiscitis may be the cause, so careful analysis of imaging is necessary.

Purpose: To investigate the fusion construct properties, construct length, intervertebral prosthesis (IVP) selection, bone grafting methods, complications management, and follow-up outcomes of spondylodiscitis fusion., Method: This case series was conducted in Al-Zahra University referral hospital from March 2016 to November 2021. All the surgery-eligible patients were enrolled. Those who did not participate or failed the neurosurgical intervention were excluded. A unified neurosurgical protocol was defined. After operation and follow-up, all variables were documented. IBM SPSS v.26 was used for data analysis. P-value ≤ 0.05 was considered significant., Result: Ninety-two patients were reviewed in the final analysis with 65.2 % males. The mean age was 55.07 ± 14.22 years old. The most frequent level of pathology and surgery was the lumbar spine (48.9 %). Short and long constructs were almost equally used (57.6 and 42.4 %, respectively). Bone graft mixture was the dominant IVP (75 %). The most frequent persistent postoperative symptom was back pain (55.4 %), while the neurological deficits resolution rate was 76.7 %. The fusion rate was 92.3 %. Proximal junctional kyphosis incidence was 16.3 % and had a significant association with on-admission neurological symptoms, thoracic and thoracolumbar junction involvements (p < 0.05). Follow-up Oswestry disability index scores showed 44.6 % of the patients had mild or no functional disabilities. Advanced age, On-admission deficits, comorbidities, titanium cages, and poor fusion status were associated with poor functional outcomes and higher mortality rates (P < 0.05)., Conclusion: The introduced neurosurgical protocol could effectively achieve acceptable SD treatment, spine stabilization, and fusion with low long-term surgical complications. Autologous bone graft mixture in comparison to titanium cages showed a higher fusion rate with a lower mortality rate. Patients with older age, neurological symptoms, and comorbidities are expected to experience less favorable clinical outcomes., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2023.

Background: Patients in low- and middle-income countries (LMICs) have substantial treatment abandonment and non-adherence with outpatient oral medications. This work sought to investigate outcomes of postoperative discitis treated with debridement and a novel technique focused on reducing outpatient antibiotic requirement in an LMIC setting., Methods: This study, conducted and reported following STROBE guidelines, reviewed outcomes of all patients with postoperative discitis who had been debrided by 1 neurosurgeon in a resource-limited setting during 2008-2020. Patients had undergone single-level L4-L5 or L5-S1 discectomy elsewhere, later developing magnetic resonance imaging-confirmed discitis. After non-response or deterioration following intravenous antibiotics, patients underwent early debridement, followed by in-patient antibiotic instillation into disc space for 2 weeks via drain. Study outcomes were modified Kirkaldy-Willis Grade, Japan Orthopaedic Association (JOA) score, and visual analog scale (VAS) score, all assessed at 1 year., Results: Twelve patients were included, 10 male and 2 female, with median age of 46 (IQR 3.5) years. Debridement was done after median 82.5 (IQR 35) days and took median time of 105 (IQR 17.5) minutes. VAS scores (mean ± SD) decreased from 9.25 ± 0.75 preoperatively to 0.67 ± 0.89 1 year postoperatively (mean difference 8.58, 95% CI 8.01-9.15, P < 0.001). JOA scores (mean ± SD) improved from 4.5 ± 2.94 to 26.42 ± 1.31 1 year postoperatively (mean difference 21.92, 95% CI 20.57-23.26, P < 0.001). Kirkaldy-Willis grade was excellent in 6 (50%) patients, good in 5 (41.7%), and fair in 1 (8.3%). Patients became ambulatory within 2 weeks, with no major complications during 4.15 (IQR 3.45) years of median follow-up., Conclusions: In LMICs, patients with medically refractory postoperative discitis potentially have good outcomes after debridement plus 2-week local antibiotic instillation., (Copyright © 2023 Elsevier Inc.

Spondylodiscitis, the inflammation of the vertebral bodies and the intervertebral disk space, is the reason for low back pain in a minority of cases. This is caused by various pathogens. Mycobacterium tuberculosis is responsible for 17–39% of all the cases of spondylodiscitis. On the contrast, spondylodiscitis from non tuberculous mycobacteria is extremely rare in literature. We describe a 68 -year old diabetic woman which is the first case of bone marrow involvement by M. intracellulare (member of M avium complex)with spondylodiscitis.

The incidence and significant morbidity of vertebral osteomyelitis are increasing despite the progress of diagnosis competences. Among the 50 cases of vertebral osteomyelitis managed in our centers over the past 5 years, 84% of the cases were in men. The mean age was 55 years. Sixty-two percent of patients had comorbidities and risk factors: diabetes mellitus (24%), malignancy (16%), intravenous drug use (10%) and alcoholism (4%). A source of infection was identified in 66% of cases, including postvertebral surgery infection (18%) and hematogenous infection (48%). The mean time to diagnosis was 36 days. Back pain were occurred in 90% of cases, fever (70%), neurologic deficits (40%), epidural abscesses (32%), completed vertebral bone destruction (26%) and psoas abscess (12%). A single organism was isolated in 92% of cases. Gram-positive bacteria were identified in 76% of cases, while Gram-negative bacilli (GNB) were found in 18% of cases. The presence of GNB was significantly associated with malignancy (p 0.041). The mean duration of antibiotic therapy was 123 days. Surgical treatment was performed in 41 cases: spinal stabilization (26%), drainage of abscesses (32%) and relief of compression (40%). Residual pain was found in 24% of cases, and neurologic sequelae in 22%. Cervical or thoracic localization was a risk factor for neurologic compromise (p 0.042). The epidemiology of vertebral osteomyelitis has changed; an increase in malignancy that was significantly associated with vertebral osteomyelitis due to GNB has been observed. Our study shows that the rate of neurologic complications remains high despite improved diagnostic capabilities and optimal treatment.

We report a case of spondylodiscitis and spinal abscess following haematogenous dissemination of the emerging yeast Candida dubliniensis in a human immunodeficiency virus-1 (HIV-1) and hepatitis C virus (HCV)-coinfected patient. Although C. dubliniensis is considered less virulent compared to its closest known relative Candida albicans, reports of severe fungal infections are increasing. This case indicates that the pathogenicity of C. dubliniensis may be higher than previously believed. Therefore fungal infections caused by this dimorph fungus should be kept in mind in immunocompromised patients with spondylodiscitis and spinal abscess.
