Patients with Spondylodiscitis following Chemoradiotherapy for Head and Neck Cancer in a Portuguese Cancer Hospital: A Case Report.

Introduction: Head and neck cancer is an umbrella term for tumor manifestations across the head and neck regions, including the oral cavity, pharynx (including the naso, oro, and hypopharynx), larynx, and sinuses. Treatment options for head and neck cancer include surgery, radiation therapy, chemotherapy, and immunotherapy, with specific treatment plans depending upon individual tumor location and staging, together with overall patient health status. Furthermore, definitive chemoradiotherapy (CRT) has emerged as a highly effective therapeutic option for locoregional advanced head and neck squamous cell cancer. However, such therapy has also been linked to the development of spondylodiscitis. Spondylodiscitis consists of an infection starting at the vertebral endplates and spreading into the intervertebral discs, typically manifesting in adults. Case Presentation and Conclusion: This case report describes our clinical team's experience in managing three separate cases of spondylodiscitis following CRT for head and neck tumors that presented at our clinic for diagnosis and treatment in order to identify predisposing factors that underlie the link between CRT and spondylodiscitis.

Distal Junctional Failure due to Spondylodiscitis in a Patient with Long Posterior Fixation for Ossified Longitudinal Ligament and Ossified Ligamentum Flavum.

Introduction: Distal junctional failure (DJF) is underreported when compared to proximal junctional failure. DJF arising due to spondylodiscitis has never been reported in the literature. Case Report: A 45-year-old lady with a body mass index of 33 presented with a long-standing inability to walk due to myelopathy secondary to continuous ossified posterior longitudinal ligament and ossified ligamentum flavum. Posterior fusion and laminectomy were done from D2 to L2. She had an initial wound breakdown with a surgical site infection, but after 6 weeks, she developed spondylodiscitis at the distal instrumented vertebra, leading to DJF. She was started on appropriate antibiotics and an extension of fusion. Conclusion: This report demonstrates and discusses the management of a rare case of DJF arising due to spondylodiscitis of the last instrumented vertebra.

Brucella spondylodiscitis that affected both cervical and lumbar spines: a rare case report from Syria.

Introduction and importance: Brucellosis, the most common microbial zoonotic disease in the world, is endemic in both industrialized and underdeveloped countries. Between 2 and 53% of patients with brucellosis, patients develop spondylitis, and people between the ages of 50 and 60 are the most commonly affected. It mostly affects the lumbar vertebrae (L4 and L5 in particular) and the thoracic vertebrae. Case presentation: A 52-year-old patient was brought to the neurological clinic after complaining of lower back discomfort, reduced mobility, and lower extremity weakness for 6 weeks. Both the cervical and lumbar columns were the sites of the specific discomfort. MRI showed cervical and lumbar discitis. Clinical discussion: A high titre of anti-brucella antibodies was found by serology testing. He was treated with oral doxycycline (100 mg, two times daily), rifampicin (900 mg) orally once daily, and gentamicin (400 mg) once daily. The patient had massive improvement after 3 months of treatment. Conclusions: This case should serve as a reminder to healthcare providers to keep a high index of suspicion for uncommon infections, including Brucella species, in patients exhibiting discitis symptoms, especially when traditional microbiological gram stain and culture are negative.

Spondylodiscitis after sacral colpopexy: diagnose early to treat earlier.

Spondylodiscitis following sacral colpopexy for Pelvic Organ Prolapse (POP) represents a rare complication with severe consequences. Authors performed a literature search, from 2000 to 2022, to set a narrative review of literature. Spondylodiscitis is an uncommon but dangerous side effect of a routine surgical treatment that needs to be identified and treated right away to prevent worsening clinical consequences. Suboptimal dissection of the sacral promontory and/or site infection are associated with spondylodiscitis. When spondylodiscitis is suspected, advanced imaging methods should be used, and surgical excision shouldn't be put off after a failed course of treatment. Authors presented a case-video of a 68-year-old woman who reported severe lower back pain 7 weeks after surgery, in which sacral spondylodiscitis was diagnosed and laparoscopically treated. In this case, a laparoscopic tack and mesh removal from promontory was carried out following the patient's continued lower back pain and the antibiotic therapy's incomplete radiological remission of spondylodiscitis. The patient's radiological findings and symptoms completely resolved two weeks following the procedure.

Value of Spinal Infection Treatment Evaluation Score, Pola Classification, and Brighton Spondylodiscitis Score from Decision to Surgery in Patients with Spondylodiscitis: A Receiver-Operating Characteristic Curve Analysis.

Study Design: This was a retrospective study. Purpose: This study aimed to assess the value of the Spinal Infection Treatment Evaluation (SITE) score, Brighton Spondylodiscitis Score (BSDS), and Pola classification to predict the need for surgical intervention in patients with spondylodiscitis. Overview of Literature: Spondylodiscitis is a rare disease, and the prediction of its outcome is crucial in the decision-making process. Methods: All case records were assessed to extract information on the American Spinal Injury Association (ASIA), Visual Analog Scale (VAS), and Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) scores before and after surgery. The SITE score, Pola classification, and BSDS were recorded. The receiver-operating characteristic (ROC) curve analysis and the area under the curve (AUC) were applied to estimate the predictive ability of the scoring systems. Patients' satisfaction with surgery outcomes was evaluated using the VAS, ASIA, JOABPEQ, and Likert scale for quality-of-life evaluation. Results: In all 148 patients, case records were reviewed. The mean±standard deviation age of the patients was 54.6±14.7 years. Of these, 112 patients underwent surgery. The AUC scores were 0.86, 0.81, and 0.73 for the SITE score, BSDS, and Pola classification, respectively. In the comparison of the AUC of ROC curves, SITE score vs. BSDS showed a significantly greater AUC, 0.13 (Z =2.1, p =0.037); SITE score vs. Pola classification, 0.05 (Z =0.82, p =0.412); and Pola classification vs. BSDS, 0.08 (Z =1.22, p =0.219). The optimal cutoff score was 8.5 (sensitivity, 80.6%; specificity, 81.2%) for the SITE score and 9.5 (sensitivity, 52.8%; specificity, 83.0%) for the BSDS in the decision to surgery. VAS back pain and JOABPEQ subscales showed a significant difference when compared with preoperative scores. According to ASIA grading, none of the patients experienced neurological deterioration. Overall, patients' satisfaction was observed. Conclusions: The findings suggest that the SITE score is a useful measure and helps clinicians make clinically sound decisions in patients with spondylodiscitis.

Lower specificity of the ESC2023 diagnostic criteria for infective endocarditis when spondylodiscitis is regarded as a vascular phenomenon.

The ESC diagnostic criteria for infective endocarditis (IE) added spondylodiscitis as minor diagnostic criterion. Of patients with Staphylococcus aureus, streptococcal or Enterococcus faecalis bacteremia, 11 of 1807 episodes were reclassified to definite IE of which nine were not treated as IE. Spondylodiscitis as a minor criterion decreases specificity of the criteria.

Sonographic diagnosis of spondylodiscitis in a young child.

Sonographic diagnosis of spondylodiscitis is described in a 21-month-old girl who presented with altered gait. Spondylodiscitis, also referred to as discitis-osteomyelitis, is an infection of the intervertebral disc and adjacent vertebrae. The imaging modality of choice is spinal magnetic resonance imaging. Our case is the first description in the English language of the sonographic diagnosis of spondylodiscitis. Pediatric radiologists and sonographers should be acquainted with its features, for both incidental and intentional diagnosis.

The projected increase of vertebral osteomyelitis in Germany implies a demanding challenge for future healthcare management of aging populations.

PURPOSE: Since an increase in the occurrence of native vertebral osteomyelitis (VO) is expected and reliable projections are missing, it is urgent to provide a reliable forecast model and make it a part of future health care considerations. METHODS: Comprehensive nationwide data provided by the Federal Statistical Office of Germany were used to forecast total numbers and incidence rates (IR) of VO as a function of age and gender until 2040. Projections were done using autoregressive integrated moving average model on historical data from 2005 to 2019 in relation to official population projections from 2020 to 2040. RESULTS: The IR of VO is expected to increase from 12.4 in 2019 to 21.5 per 100,000 inhabitants [95% CI 20.9-22.1] in 2040. The highest increase is predicted in patients over 75 years of age for both men and women leading to a steep increase in absolute numbers, which is fourfold higher compared to patients younger than 75 years. While the IR per age group will not increase any further after 2035, the subsequent increase is due to a higher number of individuals aged 75 years or older. CONCLUSIONS: Our data suggest that increasing IR of VO will seriously challenge healthcare systems, particularly due to demographic change and increasing proportions of populations turning 75 years and older. With respect to globally fast aging populations, future health care policies need to address this burden by anticipating limitations in financial and human resources and developing high-level evidence-based guidelines for prevention and interdisciplinary treatment.

Bacterial and Viral Infectious Disease of the Spine.

Spinal infections are a diverse group of diseases affecting different compartments of the spine with variable clinical and imaging presentations. Diagnosis of spinal infections is based on a combination of clinical features, laboratory markers, and imaging studies. Imaging plays a pivotal role in the diagnosis and management of spinal infections. The characteristic imaging manifestations of bacterial and viral infections in the spine are discussed with key teaching points emphasized.

Antimicrobial Treatment Challenges in the Management of Infective Spondylodiscitis Associated with Hemodialysis: A Comprehensive Review of Literature and Case Series Analysis.

Infective spondylodiscitis (ISD), the infection of vertebral bodies and surrounding tissues, is a rare complication with major impact on the long-term survival of hemodialysis (HD) patients. Although the most frequent etiology is staphylococcal, identifying these pathogens in blood cultures and biopsy cultures is often difficult. This paper aims to present suitable antibiotic combinations for the treatment of these patients, which is usually challenging in the case of an unidentified pathogen. We presented the therapies applied for 13 HD patients and 19 patients without chronic kidney disease (CKD), diagnosed with ISD between 2013 and 2023 in Bihor County. The percentage of positive blood cultures was low in both groups (30.78% HD vs. 15.78% non-HD). The average length of antibiotic therapy was 5.15 weeks in HD patients and 6.29 weeks in non-HD patients. The use of Carbapenem alone (e.g., Meropenem) for an average of 19.6 days for patients in HD when the pathogen was not identified has proven to be efficient in most cases, similarly to using Vancomycin and Fluoroquinolone/Cephalosporines in combination. Regarding the non-CKD patients, the use of Clindamycin in various combinations for an average of 30.3 days has proven to be efficient in more than 90% of cases of ISD with a nonidentified pathogen. Within 2 years after ISD was diagnosed, 12 of the 13 HD patients passed away, mainly due to cardiovascular causes. Unfortunately, there are no guidelines in the literature concerning the empiric treatment of ISD in the particular case of HD patients. Upon checking the literature on PubMed and Google Scholar, only 10 studies provided relevant data regarding ISD treatment for HD patients. More data about the treatment and evolution of these patients is needed in order to elaborate a truly relevant metanalysis.

Single- and Multilevel Corpectomy and Vertebral body replacement for treatment of spinal infections. A retrospective single-center study of 100 cases.

Background: The optimal operative approach for treating spinal infections remains a subject of debate. Corpectomy and Vertebral Body Replacement (VBR) have emerged as common modalities, yet data on their feasibility and complication profiles are limited. Methods: This retrospective single-center study examined 100 consecutive cases (2015-2022) that underwent VBR for spinal infection treatment. A comparison between Single-level-VBR and Multi-level-VBR was performed, evaluating patient profiles, revision rates, and outcomes. Results: Among 360 cases treated for spinal infections, 100 underwent VBR, located in all spinal regions. Average clinical and radiologic follow-up spanned 1.5 years. Single-level-VBR was performed in 60 cases, Two-level-VBR in 37, Three-level-VBR in 2, and Four-level-VBR in one case.Mean overall sagittal correction reached 10° (range 0-54°), varying by region. Revision surgery was required in 31 cases. Aseptic mechanical complications (8% pedicle screw loosening, 3% cage subsidence, 6% aseptic adjacent disc disease) were prominent reasons for revision. Longer posterior constructs (>4 levels) had significantly higher revision rates (p < 0.01). General complications (wound healing, hematoma) followed, along with infection relapse and adjacent disc infection (9%) and neurologic impairment (1%).Multilevel-VBR (≥2 levels) displayed no elevated cage subsidence rate compared to Single-level-VBR. Three deaths occurred (43-86 days post-op), all in the Multi-level-VBR group. Conclusion: This study, reporting the largest number of VBR cases for spinal infection treatment, affirmed VBR's effectiveness in sagittal imbalance correction. The overall survival was high, while reinfection rates matched other surgical studies. Anterior procedures have minimal implant related risks, but extended dorsal instrumentation elevates revision surgery likelihood.

Optic Neuritis and Vertebral Osteomyelitis: An Uncommon Presentation of Cat-Scratch Disease.

In cat-scratch disease (CSD), hematogenous spread may result in atypical presentations. Ocular manifestations develop in a minority of patients, with treatment being important in reducing long-term visual sequelae. Bone infection is rare. We present the case of a 52-year-old woman, with close contact with cats, reporting acute unilateral blurred vision and presenting papilledema, optic disc pallor, and peripapillary hemorrhage. Etiologic study of optic neuritis revealed an elevated positive Bartonella IgG; hence, treatment for CSD with doxycycline plus rifampin and corticosteroids was started. Concomitant lumbar pain of increasing intensity warranted magnetic resonance imaging, which revealed L3-L4 vertebral osteomyelitis with spondylodiscitis. Given the temporal link with CSD diagnosis and the significant clinical improvement since its treatment was started, an etiologic link was presumed and antibiotics were prolonged. This case stands out for the presence of distinct atypical CSD manifestations in the same patient. Further studies are needed to determine the optimal treatment for rare manifestations, particularly bone infection.

Can gas and infection coexist in the intervertebral disc? A retrospective analysis of percutaneously biopsied suspected discitis-osteomyelitis cases.

OBJECTIVES: To retrospectively evaluate the correlation between intradiscal gas and infection in patients percutaneously biopsied for suspected discitis-osteomyelitis. MATERIALS AND METHODS: We retrospectively reviewed all CT-guided discitis-osteomyelitis biopsies performed between 2002 and 2022. Two independent trained musculoskeletal radiologists evaluated for presence of gas on CT and/or MRI within 1 week of the biopsy. Disagreements were resolved by a third musculoskeletal radiologist. CT was considered the gold standard for the detection of intradiscal gas. Pathology, microbiology, and imaging and clinical follow-up were used as the gold standard for presence of infection. Interrater agreement on CT and MRI, sensitivity, and positive predictive value were calculated, using the presence of gas as an indicator (test positive) for "no infection." RESULTS: There were 284 biopsies in 275 subjects (mean age 58 ± 1.0 (range 4-99) years; 101 (37%) females and 174 (63%) males). Of the biopsies, 12 (4%) were cervical, 80 (28%) were thoracic, 192 (68%) were lumbar, and 200 (70%) were considered true discitis-osteomyelitis based on pathology, imaging, and clinical follow-up. Interrater agreement was excellent for CT (kappa = 0.83) and poor for MRI (kappa = - 0.021). The presence of gas had a 94% specificity and 76% negative predictive value for the absence of infection. CONCLUSION: CT is the preferred method for detecting intradiscal gas. The presence of gas means that discitis-osteomyelitis is unlikely. If intradiscal gas is present in the setting of discitis-osteomyelitis, the gas bubbles tend to be smaller and fewer in number.

Dorsal Lytic Lesions: Cancer or Infection?

Infectious spondylodiscitis is a rare disease and typically presents with an insidious progression characterized by spinal pain that usually starts gradually and progressively worsens over several weeks to months. It occurs through three main mechanisms: direct contamination in cases of trauma or surgery, hematogenous dissemination, or through contiguity. We report the case of a 63-year-old male, admitted due to a history of dorsolumbar pain after falling from a height of 1.5 meters, with four months of evolution, without other accompanying symptoms, and refractory to anti-inflammatory and analgesic therapy. Initial laboratory evaluation revealed normocytic and normochromic anemia and a slight elevation in C-reactive protein. Computed tomography of the spine showed pathological fractures of T7-T9. A percutaneous biopsy was performed, positive for methicillin-sensitive Staphylococcus aureus, and the patient underwent 12 weeks of targeted antibiotic therapy. A surgical procedure with percutaneous posterior arthrodesis from T4 to T12 was performed. With this case, the authors aim to emphasize the importance of biopsy as a complementary diagnostic method to imaging studies in the diagnosis of spondylodiscitis, with the possibility of identifying the causative agent.

Application of Nuclear Medicine Techniques in Musculoskeletal Infection: Current Trends and Future Prospects.

Nuclear medicine has become an indispensable discipline in the diagnosis and management of musculoskeletal infections. Radionuclide tests serve as a valuable diagnostic tool for patients suspected of having osteomyelitis, spondylodiscitis, or prosthetic joint infections. The choice of the most suitable imaging modality depends on various factors, including the affected area, potential extra osseous involvement, or the impact of previous bone/joint conditions. This review provides an update on the use of conventional radionuclide imaging tests and recent advancements in fusion imaging scans for the differential diagnosis of musculoskeletal infections. Furthermore, it examines the role of radionuclide scans in monitoring treatment responses and explores current trends in their application. We anticipate that this update will be of significant interest to internists, rheumatologists, radiologists, orthopedic surgeons, rehabilitation physicians, and other specialists involved in musculoskeletal pathology.

Drug eluting bioactive glass ceramics for fusion in spondylodiscitis: a pilot study.

Retrospective observational study. To determine the efficacy and safety of bioactive glass ceramics mixed with autograft in the treatment of spondylodiscitis. Thirty-four patients with spondylodiscitis underwent surgery using autologous bone graft augmented by antibiotic loaded bioactive glass ceramic granules. Twenty-five patients aging 6 to 77, completed 1-year follow-up. The lumbosacral junction was affected in 3, lumbar spine in 13, one each in the dorso-lumbar junction and sacrum, and 7 dorsal spines. The organism isolated was Mycobacterium tuberculosis in 15, Methicillin sensitive Staphylococcus aureus (MSSA) in 4, Pseudomonas aeruginosa in 4, Klebsiella pneumoniae in one, Burkholderia pseudomallei in 1, and mixed infections in 2. All patients had appropriate antibiotic therapy based on culture and sensitivity. Clinical and radiological evaluation of all the patients was done at 6 weeks, 3 months, 6 months, and 12 months after the surgery. Twenty-three patients improved clinically and showed radiographic fusion between 6 and 9 months. The patient with Burkholderia infection died due to fulminant septicemia with multi organ failure while another patient died at 9 months due to an unrelated cardiac event. The mean Visual Analogue Score (VAS) at the end of 1-year was 2 with radiological evidence of fusion in all patients. There were no re-infections or discharging wounds, and the 30-day re-admission rate was 0. Bioactive glass ceramics is a safe and effective graft expander in cases of spondylodiscitis. The absorption of antibiotics into the ceramic appears to help the elimination of infection.

Posterior Decompression and Fusion for Cervical Spondylodiscitis due to Osteoradionecrosis after Head-and-Neck Cancer Radiotherapy: Two Case Reports.

Introduction: Cervical spondylodiscitis due to osteoradionecrosis (ORN) after head-and-neck cancer radiotherapy is a severe complication. However, there are few reports on the surgical treatment of this condition. Case Report: We report two cases of cervical spondylodiscitis due to ORN, which were successfully treated with posterior decompression and fusion. The first case was in a 73-year-old male patient with spondylodiscitis at C3-C5, due to ORN. A posterior fusion of the spine (C2-T1) was performed, and a biopsy was conducted at a site separate from the incision for fusion. The second case was in a 76-year-old female patient with spondylodiscitis due to C4-C7 ORN. Cervical posterior decompression and fusion (C2-Th2) were performed, and decompression (C5-6) was conducted through an incision separate from that for the fusion.An anterior approach was avoided in both cases because of radiation-induced tissue changes. For these two patients with cervical spondylodiscitis due to ORN, surgery resulted in an improvement of infection and neurological deficits by posterior spinal fusion, isolation from decompression or biopsy of the infected area, and antibiotic treatment. Conclusion: Posterior decompression and fusion are effective for spondylodiscitis in the cervical spine after head-and-neck radiotherapy, treating both infection and neurological deficits. Spinal fusion that avoids the level of the infected vertebral body and decompression from separate skin incision sites may prevent the spread of infection. An anterior approach should be avoided because the risk of esophageal perforation and posterior pharyngeal wall defects is high.

Campylobacter coli enteritis associated with Campylobacter fetus bacteremia, spondylodiscitis, and late CIED-related endocarditis, a case report.

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.

Spondylodiscitis following perforated acute appendicitis in a 14-year-old female: A case report.

INTRODUCTION AND IMPORTANCE: Acute appendicitis is a common surgical emergency, often resulting in perforation and increased morbidity. Up to 55 % of children with complicated appendicitis may experience a complication such as infection, bowel obstruction, or unplanned hospital re-admission (Blakely et al., 2011 [23]). However, the development of infectious spondylodiscitis following appendectomy is an extremely rare complication, particularly in pediatric patients. We present the first reported case of lumbar spondylodiscitis occurring post-perforated appendicitis in a 14-year-old female, highlighting the importance of recognizing and managing uncommon complications. CASE PRESENTATION: A previously healthy 14-year-old female underwent urgent appendectomy for perforated appendicitis. Postoperatively, she developed severe back pain and immobility. Imaging revealed early lumbar discitis, and Pseudomonas aeruginosa was isolated from the surgical site. The patient received multiple antibiotic regimens, including vancomycin, ceftazidime, and meropenem, resulting in clinical improvement. CLINICAL DISCUSSION: Infectious spondylodiscitis is typically hematogenously spread or due to direct inoculation. In this case, the spread from a contiguous focus of infection without vascular insufficiency is suspected. The coexistence of appendicitis and spondylodiscitis poses diagnostic challenges, requiring a multidisciplinary approach for accurate diagnosis and appropriate treatment. CONCLUSION: This unique case highlights the need for vigilance in recognizing rare complications of appendicitis, such as infectious spondylodiscitis. Early diagnosis and tailored antibiotic therapy are crucial for optimal outcomes. Further research is needed to explore the underlying mechanisms and risk factors associated with this rare complication.

An Uncommon Cause of Nocturnal Crying and Discomfort: A Case of a 15-month-old Girl With Spondylodiscitis.

Nocturnal crying in toddlers has a broad spectrum of causes, including psychosocial and somatic causes, whereby the majority are self-limiting and do not need referral to specialist medical care. Although uncommon, atypical presentations of nocturnal crying-such as spondylodiscitis-require referral to specialist medical care, especially when combined with discomfort. In this case report, we present a case of a 15-month-old girl with an atypical presentation of nocturnal crying in combination with back pain.
