RESUMEN
BACKGROUND: Spondylodiscitis can be a disabling and life-threatening infection. Ascorbic Acid is crucial for neutrophil function and collagen formation. Its association and clinical relevance in spondylodiscitis has not been previously examined. AIMS: To determine the prevalence, characteristics, and clinical outcomes of spondylodiscitis patients with Ascorbic Acid deficiency. METHODS: Sixty-eight consecutive patients admitted with spondylodiscitis, between December 2021 and August 2023 were included. Clinical characteristics, Ascorbic Acid levels and clinical outcomes were evaluated. RESULTS: Thirty-seven patients had Ascorbic Acid levels taken during admission. The median initial Ascorbic Acid level was 15 µmol/L with an IQR 6.5-27 µmol/L. Depletion defined as <28 µmol/L was present in 78% of patients. Deficiency defined as ≤11 µmol/L was present in and 46% of patients. Patients with depletion were more likely to require Intensive Care Admission (absolute risk increase = 24.1%; 2.6%-45.7%). Fifteen patients had repeat serum levels taken during admission with median increase of 17 µmol/L and an IQR 0-26 µmol/L. Patients that received supplementation had a significantly greater increase in Ascorbic Acid levels compared with those that did not receive supplementation (P = 0.002). CONCLUSION: Ascorbic acid deficiency is highly prevalent amongst spondylodiscitis patients. Depletion was associated with worse outcomes. Replacement significantly increased serum levels in comparison to standard hospital diet. The clinical significance of replacement remains to be evaluated.

OBJECTIVES: Knowledge of Candida spondylodiscitis is limited to case reports and smaller case series. Controversy remains on the most effective diagnostical and therapeutical steps once Candida is suspected. This systematic review summarized all cases of Candida spondylodiscitis reported to date concerning baseline demographics, symptoms, treatment, and prognostic factors. METHODS: A PRISMA-based search of PubMed, Web of Science, Embase, Scopus, and OVID Medline was performed from database inception to November 30, 2022. Reported cases of Candida spondylodiscitis were included regardless of Candida strain or spinal levels involved. Based on these criteria, 656 studies were analyzed and 72 included for analysis. Kaplan-Meier curves, Fisher's exact, and Wilcoxon's rank sum tests were performed. RESULTS: In total, 89 patients (67% males) treated for Candida spondylodiscitis were included. Median age was 61 years, 23% were immunocompromised, and 15% IV drug users. Median length of antifungal treatment was six months, and fluconazole (68%) most commonly used. Thirteen percent underwent debridement, 34% discectomy with and 21% without additional instrumentation. Median follow-up was 12 months. The two year survivorship free of death was 80%. The two year survivorship free of revision was 94%. Younger age (p = 0.042) and longer length of antifungal treatment (p = 0.061) were predictive of survival. CONCLUSION: Most patients affected by Candida spondylodiscitis were males in their sixties, with one in four being immunocompromised. While one in five patients died within two years of diagnosis, younger age and prolonged antifungal treatment might play a protective role.

Pyogenic spondylodiscitis presents significant diagnostic and therapeutic challenges. In Germany, a comprehensive understanding of its epidemiology and inpatient management outcomes is limited, hindering the optimisation of therapeutic strategies. This study aimed to characterise the evolving epidemiological trends of pyogenic spondylodiscitis in Germany, and concurrently evaluate inpatient management strategies and outcomes. We performed a retrospective population-based study of spondylodiscitis cases in Germany from 2005 to 2021, utilising data from the German Federal Statistical Office database. The parameters assessed were incidence trends, demographic characteristics, inpatient management strategies, and inpatient mortality. The study found a significant rise in the population-adjusted incidence of spondylodiscitis in Germany from 2005 to 2021, increasing by 104% from 5.4 to 11.0 cases per 100,000 individuals (p < 0.001). The highest number of diagnoses was recorded in 2019. Age group-adjusted data revealed the largest relative changes in the "90 + " age group, followed by the "80-89" and "70-79" age groups. These increases were not solely attributable to population changes but were also confirmed after calculating the age-group-adjusted incidence rates. Additionally, our statistical analysis demonstrated that both age and year significantly influenced the incidence of spondylodiscitis. Over the same period, inpatient mortality also surged significantly by 347% (p < 0.001), with the highest increase recorded in the 90 + age group, observing a 2450% rise (p < 0.001). The mean length of inpatient stay decreased by 15% (p < 0.05). Concurrently, there was a significant increase in surgical interventions using spinal stabilisation procedures (p < 0.001), which might suggest a shift in the treatment paradigm for spondylodiscitis. The results underscore a concerning rise in spondylodiscitis incidence and mortality in Germany, particularly affecting the ageing population. A notable shift towards surgical intervention was observed. The data highlights the urgent necessity for high-level evidence studies comparing surgical versus conservative treatment, thereby guiding optimised therapeutic strategies.

The incidence of infectious spondylodiscitis (IS) has increased in recent years due to an increase in the numbers of older patients with chronic diseases, as well as patients with immunocompromise, steroid use, drug abuse, invasive spinal procedures, and spinal surgeries. However, research focusing on IS in the general population is lacking. This study investigated the incidence and treatment trends of IS in South Korea using data obtained from the Health Insurance Review and Assessment Service. A total of 169,244 patients (mean age: 58.0 years) diagnosed from 2010 to 2019 were included in the study. A total of 10,991 cases were reported in 2010 and 18,533 cases in 2019. Hence, there was a 1.5-fold increase in incidence rate per 100,000 people from 22.90 in 2010 to 35.79 in 2019 (P < 0.05). The incidence rate of pyogenic spondylodiscitis per 100,000 people increased from 15.35 in 2010 to 33.75 in 2019, and that of tuberculous spondylodiscitis decreased from 7.55 in 2010 to 2.04 in 2019 (P < 0.05, respectively). Elderly individuals ≥ 60 years of age accounted for 47.6% (80,578 patients) of all cases of IS. The proportion of patients who received conservative treatment increased from 82.4% in 2010 to 85.8% in 2019, while that of patients receiving surgical treatment decreased from 17.6% to 14.2% (P < 0.05, respectively). Among surgical treatments, the proportions of corpectomy and anterior fusion declined, while proportion of incision and drainage increased (P < 0.05, respectively). The total healthcare costs increased 2.9-fold from $29,821,391.65 in 2010 to $86,815,775.81 in 2019 with a significant increase in the ratio to gross domestic product. Hence, this population-based cohort study demonstrated that the incidence rate of IS has increased in South Korea. The conservative treatment has increased, while the surgical treatment has decreased. The socioeconomic burden of IS has increased rapidly.

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.

OBJECTIVE: The incidence of pyogenic spondylodiscitis is increasing, and the disease is associated with considerable morbidity, mortality, long-term healthcare utilization and societal costs. Disease-specific treatment guidelines are lacking and there is little consensus regarding optimal conservative and surgical management. This cross-sectional survey of German specialist spinal surgeons sought to determine practice patterns and degree of consensus regarding the management of lumbar pyogenic spondylodiscitis (LPS). METHODS: An electronic survey covering provider information, diagnostic approaches, treatment algorithms, and follow-up care of patients with LPS was distributed to members of the German Spine Society. RESULTS: Seventy-nine survey responses were included in the analysis. Magnetic resonance imaging is the diagnostic imaging modality of choice for 87% of respondents; 100% routinely measure C-reactive protein in suspected LPS and 70% routinely take blood cultures before therapy initiation; 41% believe that surgical biopsy to obtain microbiological diagnosis should be carried out in all cases of suspected LPS, whereas 23% believe that surgical biopsy should only be carried out when empirical antibiotic therapy proves ineffective; 38% believe an intraspinal empyema should always be surgically evacuated, regardless of spinal cord compression. The median intravenous antibiotic duration is 2 weeks. The median total duration of the antibiotic therapy (intravenous and oral) is 8 weeks. Magnetic resonance imaging is the preferred imaging modality for follow-up of both conservatively and operatively treated LPS. CONCLUSIONS: There exists considerable variation of care in the diagnosis, management, and follow-up of LPS among German spine specialists with little agreement on key aspects of care. Further research is required to understand this variation in clinical practice and to enhance the evidence base in LPS.

BACKGROUND: Staphylococcus aureus is an uncommon cause of community-acquired bacterial meningitis. We aimed to describe patients with this disease. METHODS: We evaluated clinical characteristics and outcome of adults with community-acquired S. aureus meningitis from prospective nationwide cohort studies from Denmark (2015-2020) and the Netherlands (2006-2021). Whole genome sequencing of S. aureus isolates was performed to evaluate the potential association between clonal complex and clinical characteristics. RESULTS: We evaluated 111 episodes of community-acquired S. aureus meningitis: 65 from Denmark and 46 from the Netherlands. The median age was 66 years (interquartile range [IQR] 50-74) and 43 of 111 patients were female (39%). Concomitant infectious foci were found in 95 of 107 patients (89%), most commonly endocarditis (53 of 109 [49%]) and spondylodiscitis (43 of 109 [39%]). The triad of neck stiffness, altered mental status (Glasgow Coma Scale score <14), and fever was present in only 18 of 108 patients (17%). Surgery was performed in 14 of 33 patients (42%) with spondylodiscitis and 26 of 52 (50%) with endocarditis. A favorable outcome (Glasgow Outcome Scale score 5) occurred in 26 of 111 patients (23%), while 39 (35%) died. The most common bacterial clonal complexes (CC) were CC30 (16 [17%]), CC45 (16 [17%]), CC5 (12 [13%], and CC15 (10 [11%]); no associations between CCs and concomitant foci or outcome were found. CONCLUSIONS: Community-acquired S. aureus meningitis is a severe disease with a high case fatality rate, occurring mainly in patients with concomitant endocarditis or spondylodiscitis.

PURPOSE: Discitis represents infection of the intervertebral disc and osteomyelitis of the adjacent end plates. Classically, patients present with fever and back pain. Varied presentations and lack of adherence to guidelines lead to great variation in its identification and management. The primary objective of this study was to conduct a cohort analysis, assessing the identification and management of discitis, in a busy secondary orthopaedic centre. METHODS: A retrospective study was conducted, of cases diagnosed and treated for discitis, in a secondary orthopaedic department, within the UK from January 2017 to October 2019. During this time period, all patients who underwent magnetic resonance imaging (MRI) spine were identified. Patients with MRI-proven discitis were then added into the study. RESULTS: A total of 152 MRIs showed radiographic features of discitis. Of these, only 38 had a clear clinical correlation. Back pain was the most common presenting complaint followed by fever. The commonest site of involvement was vertebral levels L5 and S1. All patients had baseline bloods, and most, but not all, had blood cultures taken. Staphylococcus aureus was the most frequently isolated, causative organism. The mainstay of treatment was intravenous flucloxacillin, with most patients requiring a minimum of six weeks. CONCLUSION: Our study has helped define the population of patients presenting with discitis, in a busy secondary orthopedic center. Analyzing over two years of data has provided us with valuable insight into the most appropriate diagnostics and management for discitis.

BACKGROUND AND OBJECTIVE: spondylodiscitis is becoming a more frequently encountered diagnosis in our clinical practice. Multimorbid and especially older patients build up a relevant portion of cases. The goal of our study was to evaluate our clinical data and to reveal specifics concerning elderly patients with spontaneous spondylodiscitis. PATIENTS AND METHODS: We retrospectively analyzed clinical data for the years from 2012 to 2014. The search was conducted on the basis of the International Classification of Diseases, 10th Revision (ICD-10) diagnoses for spondylodiscitis. Postoperative infections were not included in this study. All cases were evaluated in terms of infectious agents (in blood culture and/or computerized tomography [CT]-guided or surgical biopsy), age, and overall survival. RESULTS: Fifty-one patients with spontaneous spondylodiscitis were identified. The most frequent pathogen was methicillin-sensitive Staphylococcus aureus (MSSA; n = 21; 41.17%). Escherichia coli and S. epidermidis were each found in four patients each (7.84%). Methicillin-resistant S. aureus (MRSA), Pseudomonas aeruginosa, and S. hominis were found in three cases (5.88%). Other bacteria were found in one case (each 1.96 %). In 12 cases, there was no bacteria growth (23.53%). One of these patients revealed to have a tuberculosis infection, diagnosed after the study period (in 2015). Two-thirds of the patients were ≥65 years old (n = 34). All three patients with MRSA were >65 years old. Three of seven patients <50 years had IV drug abuse (42.86%). In these patients, rather rare infectious agents for spondylodiscitis were found (P. aeruginosa, S. hominis, Citrobacter). Mortality was 7.84% (n = 4). All of these patients were ≥67 years old, three of four (75%) were ≥75 years old. CONCLUSION: Our study of spontaneous spondylodiscitis showed a stronger representation of older patients (>65 years). Lethal outcome exclusively concerned the older age group. S. aureus was the most frequent pathogen as shown previously. MRSA infections might be more common in the older age group. Rare causative organisms mainly occurred in patients with iv drug abuse. Further evaluation through randomized multicenter studies focusing on the different subgroups and comorbidities in larger populations and correlation with appropriate treatment options is necessary.

BACKGROUND: This retrospective study analyzed the clinical characteristics and outcomes of patients with anaerobic spondylodiscitis. METHODS: From a total of 382 patients with infectious spondylodiscitis, nine patients (2.4%; two male and seven female with an average age of 67 years) with anaerobic spondylodiscitis between March 2003 and March 2017 were analyzed. RESULTS: Most of the patients (77.8%) initially presented with afebrile back pain. Hematogenous spread occurred in seven patients and postoperative infection in two patients. Bacteroid fragilis was the most common pathogen isolated from three patients. Atypical radiographic characteristics, including a vertebral fracture with the preservation of disk height or coexisting spondylolytic spondylolisthesis, occurred in four patients with hematogenous anaerobic spondylodiscitis. The eradication rate of anaerobic infection was significantly higher in the patients with hematogenous infection than in those with postoperative infection (100% vs. 0%, p = 0.0476). Anaerobic spondylodiscitis accounted for 2.4% of cases of infectious spondylodiscitis and predominantly affected the female patients. CONCLUSIONS: Diagnostic delay may occur because of atypical spinal radiographs if the patient reports only back pain but no fever. Anaerobic infection following elective spinal instrumentation has a higher recurrence rate.

BACKGROUND: Pediatric spondylodiscitis is rare, hardly diagnosed and treated due to the nonspecificity of clinical presentation and laboratory investigations, difficulty of etiologic identification and lack of management guidelines. METHODS: A retrospective study was conducted on 29 children with spondylodiscitis. Clinical, hematic and radiologic data were collected and compared between 2 age-subgroups (below and from 4 years old on) to investigate age-related differences. Epidemiologic, management and follow-up data were also described. RESULTS: Slight male predominance and a peak of incidence <2 years were observed. Symptoms were significantly differently distributed in the 2 age-subgroups: children <4 years showed mainly refusal/inability to sit or bear weight, irritability, limping and poor general conditions; children ≥4 years most frequently had back pain and fever, and pain upon palpation of the spine. The lumbar spine and more than 1 vertebra were most frequently involved. Median diagnostic delay of 12 days was observed, without significant difference between age-subgroups, and delay >2 months was always associated with multivertebral involvement and complications. All children were treated with broad-spectrum antibiotics for a median of 12 weeks. Only in 1 complicated case, surgical treatment was also required. CONCLUSIONS: The clinical presentation of spondylodiscitis may be age-specific, with younger children often exhibiting subtle signs and symptoms. Broad-spectrum antibiotics covering for Staphylococcus aureus should be initiated as soon as possible and performed many weeks, being effective in treating the infection without clinical sequelae, even in patients with comorbidities. Surgical treatment should be reserved for complicated cases with neurologic involvement.

AIMS: The aims of this study were to determine the diagnostic yield of image-guided biopsy in providing a final diagnosis in patients with suspected infectious spondylodiscitis, to report the diagnostic accuracy of various microbiological tests and histological examinations in these patients, and to report the epidemiology of infectious spondylodiscitis from a country where tuberculosis (TB) is endemic, including the incidence of drug-resistant TB. METHODS: A total of 284 patients with clinically and radiologically suspected infectious spondylodiscitis were prospectively recruited into the study. Image-guided biopsy of the vertebral lesion was performed and specimens were sent for various microbiological tests and histological examinations. The final diagnosis was determined using a composite reference standard based on clinical, radiological, serological, microbiological, and histological findings. The overall diagnostic yield of the biopsy, and that for each test, was calculated in light of the final diagnosis. RESULTS: The final diagnosis was tuberculous spondylodiscitis in 250 patients (88%) and pyogenic spondylodiscitis in 22 (7.8%). Six (2.1%) had a noninfectious condition-mimicking infectious spondylodiscitis, and six (2.1%) had no definite diagnosis and improved without specific treatment. The diagnosis was made by image-guided biopsy in 152 patients (56%) with infectious spondylodiscitis. Biopsy was contributory in identifying 132/250 patients (53%) with tuberculous spondylodiscitis, and 20/22 patients (91%) with pyogenic spondylodiscitis. Histological examination was the most sensitive diagnostic modality, followed by Xpert MTB/RIF assay. CONCLUSION: Image-guided biopsy has a reasonably high diagnostic yield in patients with suspected infectious spondylodiscitis. A combination of histological examination, Xpert MTB/RIF assay, bacterial culture, and sensitivity provides high diagnostic accuracy in a country in which TB is endemic.

PURPOSE: In patients with pyogenic spondylodiscitis, surgery is considered the treatment of choice to conduct proper debridement, stabilise the spine and avoid extended bed rest, which in turn is a risk factor for complications such as deep vein thrombosis and pulmonary embolism. METHODS: We conducted a retrospective clinical study with analysis of a group of 99 patients who had undergone treatment for pyogenic discitis at our institution between June 2012 and August 2017. Included parameters were age, sex, disease pattern, the presence of deep vein thrombosis, resuscitation, in-hospital mortality, present anticoagulation, preexisting comorbidities, tobacco abuse, body mass index, microbiological germ detection and laboratory results. RESULTS: Among the analysed cohort, 12% of the treated patients for pyogenic spondylodiscitis suffered from a radiologically confirmed pulmonary embolism. Coronary heart disease (p < 0.01), female sex (p < 0.01), anticoagulation at admission (p < 0.01) and non-O blood type (p < 0.001) were associated with development of pulmonary embolism. Pulmonary embolism was significantly associated with resuscitation (p < 0.005) and deep vein thrombosis (p < 0.001). Neurosurgery was not associated with increased risk for pulmonary embolism compared to conservative-treated patients (p > 0.05). CONCLUSION: Surgery for pyogenic spondylodiscitis was not associated with an elevated risk of pulmonary embolism in our analysis. However, we describe several risk factors for pulmonary embolism in this vulnerable cohort. Prospective studies are necessary to improve prevention and postoperative management in patients with pyogenic spondylodiscitis.

BACKGROUND CONTEXT: Spondylodiscitis is the most common spinal infection of which the incidence has increased and the peak prevalence is between 50 and 70 years of age. Spondylodiscitis is often a complication of a distant infection. Early diagnosis can be challenging, and although improvements in diagnostic techniques and modern therapy have diminished the mortality of the disease, current literature about the outcome of spondylodiscitis is scarce. PURPOSE: To evaluate the long-term clinical outcome of patients who suffered from spondylodiscitis. STUDY DESIGN: A two-center cross-sectional study. PATIENT SAMPLE: Patients with spondylodiscitis in two large teaching hospitals in the Netherlands between 2003 and 2017. OUTCOME MEASURES: Visual Analogue Scale (VAS) for back pain, Oswestry Disability Index (ODI) for function, and Short Form 36 (SF-36) for general quality of life of spondylodiscitis patients. METHOD: Eligible patients were identified from electronic patient databases and completed multiple patient reported outcome measures after obtaining informed consent. General demographic and clinical information (age, sex, medical history) were extracted from the patient records. SF-36 domain scores of spondylodiscitis patients were compared with a nationwide population sample. RESULTS: 183 patients were treated for spondylodiscitis; additional questionnaires were received from 82 patients. After a median follow-up of 63 months, the overall mortality was 28%. The mean VAS for back pain was 3.5, and the mean ODI score was 22. In all SF-36 domains a significantly lower score was found in the spondylodiscitis group compared with a normative national Dutch cohort. There was a strong correlation between back pain and ODI scores (ρ=0.81, p<.05). CONCLUSIONS: Our study confirms that spondylodiscitis is a disease causing a profound impact on back pain, function and quality of life. The results suggest that chronic back pain is a debilitating problem, as it has an extensive influence on daily activities and social and psychological well-being, causing significant disability.

BACKGROUND: The association of infective endocarditis (IE) with spondylodiscitis (SD) was first reported in 1965, but few data are available about this issue. This study aimed to evaluate the prevalence of SD in patients with IE, and to determine the clinical features and the prognostic impact of this association. METHODS: We retrospectively analysed 363 consecutive patients admitted to our Department with non-device-related IE. Radiologically confirmed SD was revealed in 29 patients (8%). Long-term follow-up (average: 3 years) was obtained by structured telephone interviews; in 95 cases (13 of whom had been affected by SD), follow-up echocardiographic evaluation was also available. RESULTS: At univariable analysis, the combination of IE with SD was associated with male gender (p = 0.017), diabetes (p = 0.028), drug abuse (p = 0.009), Streptococcus Viridans (p = 0.009) and Enterococcus (p = 0.015) infections. At multivariable analysis, all these factors independently correlated with presence of SD in patients with IE. Mortality was similar in patients with and without SD. IE relapses at 3 years were associated with the presence of SD (p = 0.003), Staphylococcus aureus infection (p < 0.001), and drug abuse (p < 0.001) but, at multivariable analysis, only drug abuse was an independent predictor of IE relapses (p < 0.001; HR 6.8, 95% CI 1.6-29). At echocardiographic follow-up, SD was not associated with worsening left ventricular systolic function or valvular dysfunction. CONCLUSIONS: The association of IE with SD is not rare. Hence, patients with IE should be screened for metastatic infection of the vertebral column, especially if they have risk factors for it. However, SD does not appear to worsen the prognosis of patients with IE, either in-hospital or long-term.

OBJECTIVE: The incidence and associated risk factors for sacral osteomyelitis and sacral discitis after sacrocolpopexy remain unknown. The aim of this study was to determine the incidence of sacral osteomyelitis and discitis after minimally invasive sacrocolpopexy and their association with the method of sacral mesh fixation. METHODS: This is a retrospective cohort study of consecutive minimally invasive sacrocolpopexies performed by 11 female pelvic medicine and reconstructive surgery board-certified surgeons from January 2009 to August 2019 within a single health system. Sociodemographic, procedure, and clinical variables were abstracted from the electronic health record (EHR). We then performed a confirmatory EHR interrogation, cross-referencing procedural codes for laparoscopic and robot-assisted sacrocolpopexy and diagnostic codes for sacral osteomyelitis and sacral discitis. RESULTS: The EHR chart review identified 1,189 women who underwent laparoscopic (55.2%) and robot-assisted (44.8%) minimally invasive sacrocolpopexy, all with polypropylene mesh. Median follow-up was 7.7 months (interquartile range, 0-49.8). Titanium helical tacks were used in 52.7% patients, sutures in 41.6%, and both in 5.6%. No cases (0%) of sacral osteomyelitis or discitis were identified by chart review. The system-wide EHR interrogation of procedural and diagnostic codes identified 421 additional procedures for a total of 1,610 minimally invasive sacrocolpopexies. Among these, there were no cases (0%) of osteomyelitis or discitis. CONCLUSIONS: Sacral osteomyelitis and discitis are rare early outcomes after minimally invasive sacrocolpopexy with an incidence of less than 1/1,000 cases. Given an absence of cases, we were unable to assess for an association between method of sacral attachment and sacral osteomyelitis and sacral discitis.

BACKGROUND: Due to the unspecific symptoms of spondylodiscitis (SpD), an early radiological examination is necessary. However, controversially discussed is the need for magnetic resonance imaging of the entire spine to exclude multisegmental infections and to determine the required surgical interventions. The aims of this study were to assess the incidence of multilevel non-contiguous pyogenic SpD and compare comorbidities, pain symptoms, and subsequent surgical strategies between unifocal (uSpD) and multifocal (mSpD) SpD. METHODS: We retrospectively evaluated the data of patients with confirmed, surgically treated, pyogenic SpD who had received a total spine MRI in a single spine center between 2016 and 2018. MRI findings were classified according to Pola-classification and demographics, duration of clinical symptoms (pain and neurology) and Charlson Comorbidity-Index (CCI) results were compared between uSpD und mSpD groups. Surgical therapy was evaluated in patients with mSpD. RESULTS: uSpD was detected by MRI in 69 of 79 patients (87%). Of these, mSpD was detected in 10 patients (13%) with 21 infected segments (cervical and/ or thoracic and/ or lumbar region). Age and CCI were similar between uSpD and mSpD and 24 of all SpD regions were clinically unapparent. All patients with uSpD were treated operatively. In seven patients with mSpD, all infected levels of the spine were treated surgically in a one-stage procedure; one patient had a two-stage procedure and one patient had surgery at the lumbar spine, and an additional infected segment of the upper thoracic spine was treated conservatively. One patient died before a planned two-stage procedure was performed. CONCLUSIONS: Due to mSpD being found in approximately 13% of SpD cases, and considering the risk of overlooking an mSpD case, MRI imaging of the total spine is recommended. The detection of multiple infection levels can have an impact on the therapeutic strategy chosen.

BACKGROUND: Kingella kingae (Kk) is frequently responsible for invasive skeletal infections in children aged 3-36months. However, few outbreaks of invasive Kk infections in day care centers have been reported. The objective of the present study was to describe (a) the clinical and laboratory data recorded during an outbreak of invasive Kk skeletal infections, and (b) the management of the outbreak. METHOD: Four children from the same day care center were included in the study May and June 2019. We retrospectively analyzed the children's clinical presentation and their radiological and laboratory data. We also identified all the disease control measures taken in the day care center. RESULTS: We observed cases of septic arthritis of the wrist (case #1), shoulder arthritis (case #2), knee arthritis (case #3) ans cervical spondylodiscitis (case #4). All cases presented with an oropharyngeal infection and concomitant fever prior to diagnosis of the skeletal infection. All cases were misdiagnosed at the initial presentation. The mean (range) age at diagnosis was 10.75months (9-12). The three patients with arthritis received surgical treatment. All patients received intravenous and then oral antibiotics. In cases 1 and 2, Kk was detected using real-time PCR and a ST25-rtxA1 clone was identified. The outcome was good in all four cases. Four other children in the day care center presented with scabies during this period and were treated with systemic ivermectin. The Regional Health Agency was informed, and all the parents of children attending the day care center received an information letter. The day care center was cleaned extensively. CONCLUSION: Our results highlight the variety of features of invasive skeletal Kk infections in children and (given the high risk of transmission in day care centers) the importance of diagnosing cases as soon as possible.

Spondylodiscitis is a serious and potentially life-threatening disease. Obesity is a risk factor for many infections, and its prevalence is increasing worldwide. Thus, the aim of this study was to describe characteristics of obese patients with spondylodiscitis and identify risk factors for a severe disease course in obese patients. Between December 2012 and June 2018, clinical records were screened for patients admitted for spondylodiscitis. The final analysis included 191 adult patients (mean age 64.6 ± 14.8 years). Patient data concerning demographics, comorbidities, surgical treatment, laboratory testing, and microbiological workup were analysed using an electronic database. Patients were grouped according to body mass index (BMI) as BMI ≥ 30 kg/m2 or < 30 kg/m2. Seventy-seven patients were classified as normal weight (BMI 18.5-24.9 kg/m2), 65 as preobese (BMI 25-29.9 kg/m2), and 49 as obese (BMI ≥ 30 kg/m2). Obese patients were younger, had a higher revision surgery rate, and showed higher rates of abscesses, neurological failure, and postoperative complications. A different bacterial spectrum dominated by staphylococci species was revealed (p = 0.019). Obese patients with diabetes mellitus had a significantly higher risk for spondylodiscitis (p = 0.002). The mortality rate was similar in both cohorts, as was the spondylodiscitis localisation. Obesity, especially when combined with diabetes mellitus, is associated with a higher proportion of Staphylococcus aureus infections and is a risk factor for a severe course of spondylodiscitis, including higher revision rates and sepsis, especially in younger patients.

INTRODUCTION: Spinal epidural abscess is uncommon but potentially debilitating infection. Delay in early diagnosis may be associated with increased morbidity and mortality despite recent advances in medicine. AIM: To present the clinical course and outcome of treatment of spontaneous spinal epidural abscesses. MATERIALS AND METHODS: Thirty-four patients (20 men and 14 women) with clinical, neuroimaging and/or histological data for spinal epidural abscess were treated at the Clinic of Neurosurgery at St George University Hospital, Plovdiv, Bulgaria, for the period 2009-2018. RESULTS: The average age of patients was 62 years (21-76 years) and the ratio of men to women was 1.4:1. All patients (100%) presented with vertebralgia, 13 patients (38.2%) had additional radiculalgia, and 10 patients (29.4%) presented with sensory or motor deficit. The duration of complaints varied from 4 to 180 days. At hospital admission, only 9 patients (26.4%) had intact neurological status. The most common localization of the spinal epidural abscess was in the lumbar and lumbosacral area (52.9%), concomitant spondylodiscitis was present in 31 patients (91.2%). Twenty-four patients (70.6%) underwent emergency surgery within 24 hours, and the rest had planned surgery. Decompressive interlaminotomy or hemilaminectomy was performed in 9 patients (26.5%). The remaining 25 patients (73.5%) underwent laminectomy, in 15 patients (44.1%) it was combined with posterior pedicle screw fixation. After the treatment, 23 patients (67.6%) had a good outcome, the remaining 11 (32.4%) had a poor outcome, and 3 patients died (8.8%). CONCLUSION: In patients with spinal epidural abscess, emergency surgery is the treatment method of choice. It allows decompression of neural structures, correction of the spinal deformity, segmental stabilization and rapid mobilization of patients.
