[PMID: 37645470 PMCID: PMC10461046 DOI: 10.3389/fsurg.2023.1215240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Accepted: 08/02/2023] [Indexed: 08/31/2023] Open
Abstract
Objective The purpose of this study is to evaluate the safety and efficacy of a percutaneous endoscopic debridement and drainage for lumbar infections with early epidural abscesses. Methods Eight cases of early epidural abscess underwent lumbar intervertebral space debridement and drainage by percutaneous endoscopic. Laboratory indicators, pathogenic microorganisms and complications were documented, and the ASIA scores were used to assess preoperative and postoperative neurological function changes. Additionally, the VAS was used to evaluate the therapeutic effect. Results The average duration of the drainage tube was 11.25 ± 3.96 days (7-20 days), and the epidural abscess was eliminated after the tube was taken out. Postoperative CRP (14.40 ± 12.50 mg/L) and ESR (48.37 ± 16.05 mm/1 h) were significantly lower than the preoperative CRP (62.5 ± 61.1 mg/L) and ESR (75.30 ± 26.20 mm/1 h). The VAS score after the operation (2.50 ± 0.92 points) was significantly lower than the one before the surgery (8.25 ± 0.83 points). 5 patients experienced lower extremity pain and neurological dysfunction prior to surgery, however, after drainage, the lower extremity pain dissipated and the lower extremity muscle strength improved in one patient. All 8 patients were followed up for a period of (28.13 ± 10.15) months, including 3 patients with spinal segmental instability who had lumbar bone graft and internal fixation for the second stage. At the end of the follow-up, all 8 patients were clinically cured without any progressive nerve injury, paraplegia or recurrence of infection. Conclusion Percutaneous Endoscopic Debridement and Drainage is an effective way to drain intraspinal abscesses, thus avoiding any potential progressive harm to the spinal cord.

Abstract
This is a case of a 71-year-old female with a history of only one known medical problem (hypertension) who presented with a right sternoclavicular joint (SCJ) infection in addition to (1) a contiguous lower cervical and upper thoracic epidural phlegmon and (2) cellulitis and a phlegmon in her posterior neck, which was subcutaneous and near the lower cervical and upper thoracic spinous processes. These loci of infection developed several days after she had pricked her fingers when cutting rose bushes and were initially considered to be epidural abscesses. However, after the patient was transferred to our tertiary medical center, a neurosurgeon and radiologist determined that the cervicothoracic infections were phlegmons rather than fully developed abscesses. The phlegmons were treated with only IV antibiotics. The SCJ infection was surgically debrided, and the medial clavicle was excised. Bone and fluid cultures grew methicillin-sensitive Staphylococcus aureus (S. aureus). The patient recovered uneventfully (the final follow-up was four years later). This case is uncommon because of the concurrent SCJ infection with medial clavicle osteomyelitis, cervical-thoracic epidural, and paraspinous phlegmons.

Abstract
A 56-year-old male admitted to the hospital for generalized weakness and fever. He was treated in hospital for 10 days due to COVID-19. He did not receive any immunosuppressive therapy during admission. One day after his discharge he experienced back pain and received analgesic therapy for 10 days. About one month later he experienced severe back pain and gross hematuria. He was admitted to hospital with acute kidney injury and new-onset lower extremity muscle weakness. His renal biopsy revealed IgA nephropathy and thoracic/cervical/lumbar-spine imaging showed an epidural abscess. This is a unique case report of a patient developing an epidural abscess and acute kidney injury together as a serious complication of COVID-19 infection.

Abstract
Staphylococcus aureus is a common skin commensal with the potential to cause severe infections resulting in significant morbidity and mortality. Up to 30% of individuals are colonized with S aureus, though infection typically does not occur without skin barrier disruption. Infection management includes promptly addressing the source of infection, including sites of metastatic infection, and initiation of effective antibiotics, which should be selected based on local antibiotic susceptibility patterns. Given that S aureus colonization is a risk factor for infection, preventive strategies are aimed at optimizing hygiene measures and decolonization regimens for outpatients and critically ill children with prolonged hospitalizations.

Abstract
Spinal-epidural abscess (SEA) is believed to be primarily of haematogenous origin and very rarely as a consequence of central neuraxial blockade. Early diagnosis and pertinent management invariably improve neurological outcomes. We report a case of long-segment SEA, which was suspected during subarachnoid anaesthesia, subsequently diagnosed and managed appropriately, averting irreversible neurological deficits.

Am J Med Sci 2021; 361:485-490. [PMID: 33637307 DOI: 10.1016/j.amjms.2020.10.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/25/2020] [Accepted: 10/22/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Spinal epidural abscess (SEA) is an uncommon and highly morbid infection of the epidural space. End-stage renal disease (ESRD) patients are known to be at increased risk of developing SEA; however, there are no studies that have described the risk factors and outcomes of SEA in ESRD patients utilizing the United States Renal Data System (USRDS). METHODS To determine risk factors, morbidity, and mortality associated with SEA in ESRD patients, a retrospective case-control study was conducted using the USRDS. ESRD patients diagnosed with SEA between 2005 and 2010 were identified, and logistic regression was performed to examine correlates of SEA, as well as risk factors associated with mortality in SEA-ESRD patients. RESULTS The prevalence of SEA amongst ESRD patients was 0.39% (n = 1,697). Patients with SEA were more likely to be male [adjusted Odds Ratio (OR) = 1.22], black (OR = 1.19), diabetic (OR = 1.26), with catheter access (OR = 1.29), and less likely to be ≥65 years old (OR = 0.64). Osteomyelitis, bacteremia/septicemia, MRSA, and endocarditis were all significantly associated with increased risk of SEA (OR = 1.54-5.14). Age ≥65 years (HR = 1.45), urinary tract infections (HR = 1.26), decubitus ulcers (HR=1.37), and post-SEA paraplegia (HR = 1.25) were significantly associated with mortality among those with SEA. CONCLUSIONS As described in previous literature, risk factors for SEA included infections, diabetes, and indwelling catheters. Additionally, clinicians should be aware of the risk factors for mortality in SEA-ESRD patients. As the largest study of SEA to date, our report identifies important risk factors for SEA in ESRD patients, and novel data regarding their mortality-associated risk factors.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES The aim of this study is to identify predictive factors associated with failure of nonoperative management of spinal epidural abscess (SEA). METHODS Between January 2007 and January 2017, there were 97 patients 18 years or older treated for SEA at a tertiary referral center. Of these, 58 were initially managed nonoperatively. Details on presenting complaint, laboratory parameters, radiographic evaluation, demographics, comorbidities, and neurologic status (Frankel grades A-E) were collected. Success of treatment was defined as eradication of infection with no requirement for further antimicrobial therapy. Diagnosis of SEA was made via evaluation of imaging and intraoperative findings. Patients with repeat presentation of SEA, children, and those who were transferred for immediate surgical decompression were excluded. RESULTS Fifty-eight patients initially treated nonoperatively were included. Of these, 21 failed nonoperative management and required surgical intervention. The mean age was 60 years, 66% male, and 19% of Maori ethnicity. Abscess location was predominantly dorsal, and in the lumbar region (53%). Multivariate analysis identified Maori ethnicity, multifocal sepsis, and elevated white cell count as predictors of failure of nonoperative management. With 1 predictor the risk of failure was 44%. In the presence of 2 predictive variables, failure rate increased to 60%, and if all 3 variables were present, patients had a 75% risk of failure. CONCLUSION Thirty-six percent of patients treated nonoperatively failed nonoperative management-the failure rate was significantly increased in patients with multifocal sepsis, in patients with elevated white cell count, and in patients of Maori ethnicity.

Abstract
BACKGROUND CONTEXT Spinal epidural abscess (SEA) can cause neurologic deficits and needs urgent surgical intervention. Many clinical factors had been proposed to predict surgical outcomes in patients with SEA, but the predictive radiographic risk factors for residual neurologic deficits were not addressed sufficiently. PURPOSE To analyze the clinical and radiographic risk factors for residual neurologic deficit in patients with SEA after surgical intervention of the thoracic or lumbar spine. STUDY DESIGN/SETTING A retrospective consecutive case series. PATIENT SAMPLE From January 2005 through December 2014, 53 patients with primary SEA, confirmed by culture or histopathology, in the thoracic or lumbar spine who underwent posterior-only approach surgery at our hospital. OUTCOME MEASURES Neurologic status was assessed using the Frankel grading system preoperatively, postoperatively, and at final follow-up. METHODS The patients were allocated into two groups based on the presence of postoperative residual neurologic deficits. Patients' demographic, clinical, and factors based on magnetic resonance imaging (MRI) were analyzed for their influence on residual neurologic deficits. Clinical factors included age, sex, diabetes, comorbidities, pathogens, affected spinal levels, the interval between onset of symptoms to surgery, preoperative neurologic status, presence of cauda equina syndrome, and surgical procedures. MRI factors included the distribution of abscesses within the spinal canal, presence of ring enhancement, presence of paravertebral abscess or psoas abscess, canal compromise anteroposterior (AP) ratio and cross-sectional area ratio, abscess length, and abscess thickness. RESULTS Thirty-five of the 53 patients (66%) had preoperative neurologic deficits, and 21 of 53 patients (40%) had postoperative residual neurologic deficits. Patients' neurologic status improved significantly after the surgery (p<.001). Risk factors including age, diabetes, cauda equina syndrome, presence of anterior with posterior (A+P) dural abscess, canal compromise AP ratio, cross-sectional area ratio, abscess length, and abscess thickness were significantly correlated with postoperative residual neurologic deficits. In multivariate logistic regression analysis, age ≥70 years, preoperative cauda equina syndrome, abscess length ≥5.5 cm and abscess thickness ≥0.8 cm were the four most significant factors related to residual neurologic deficits. CONCLUSIONS In patients with SEA of the thoracic and lumbar spine, age ≥70 years, preoperative cauda equina syndrome, abscess length ≥5.5 cm and abscess thickness ≥0.8 cm were the most significant preoperative risk factors for residual neurologic deficits after surgery.

Abstract
Spinal epidural abscess (SEA) is a rare condition associated with significant morbidity and mortality. Despite advances in diagnostic medicine, early recognition of SEAs remains elusive. The vague presentation of the disease, coupled with its numerous risk factors, the diagnostic requirement for obtaining advanced imaging, and the necessity of specialized care constitute extraordinary challenges to both diagnosis and treatment of SEA. Once diagnosed, SEAs require urgent or emergent medical and/or surgical management. As SEAs are a relatively rare pathology, high-quality data are limited and there is no consensus on their optimal management. This paper focuses on presenting the treatment modalities that have been successful in the management of SEAs and providing a critical assessment of how specific SEA characteristics may render one infection more amenable to primary surgical or medical interventions. This paper reviews the relevant history, epidemiology, clinical presentation, radiology, microbiology, and treatment of SEAs and concludes by addressing the medicolegal implications of delayed treatment of the disease.

Abstract
BACKGROUND Pyogenic spondylodiscitis is a rare disease that is being diagnosed with increasing frequency in recent years. It is associated with a high morbidity and mortality. DIAGNOSIS Often, because of its nonspecific symptoms, pyogenic spondylodiscitis is diagnose with some delay. In addition to pathogen detection, MRI is the gold standard to diagnose pyogenic spondylodiscitis. Also, x-ray imaging and CT can be carried out for surgical planning and for subsequent follow-up imaging. If blood or tissue cultures are negative, open surgical biopsies should be preferred over CT-guided biopsies. THERAPY The therapy can be conservative, such as immobilization, as well as antibiotics and analgesics, or surgical. If, for example, neurological deficits, spinale instabilities or deformities, septic disease progression or extensive abscess formations are present, surgical therapy is indicated. The surgical treatment strategies depend on the severity of the disease. OUTLOOK The prognosis is dependent on a rapid diagnosis and a swift start to therapy. There is no clear evidence with regard to treatment options (conservative vs. surgical therapy).

Readmission after spinal epidural abscess management in urban populations: a bi-institutional study. J Neurosurg Spine 2020; 32:465-472. [PMID: 31756697 DOI: 10.3171/2019.8.spine19790] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2019] [Accepted: 08/28/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE The incidence of spinal epidural abscess (SEA) is rising, yet there are few reports discussing readmission rates or predisposing factors for readmission after treatment. The aims of the present study were to determine the rate of 90-day readmission following medical or surgical treatment of SEA in an urban population, identify patients at increased risk for readmission, and delineate the principal causes of readmission. METHODS Neurosurgery records from two large urban institutions were reviewed to identify patients who were treated for SEA. Patients who died during admission or were discharged to hospice were excluded. Univariate analysis was performed using chi-square and Student t-tests to identify potential predictors of readmission. A multivariate logistic regression model, controlled for age, body mass index, sex, and institution, was used to determine significant predictors of readmission. RESULTS Of 103 patients with identified SEA, 97 met the inclusion criteria. Their mean age was 57.1 years, and 56 patients (57.7%) were male. The all-cause 90-day readmission rate was 37.1%. Infection (sepsis, osteomyelitis, persistent abscess, bacteremia) was the most common cause of readmission, accounting for 36.1% of all readmissions. Neither pretreatment neurological deficit (p = 0.16) nor use of surgical versus medical management (p = 0.33) was significantly associated with readmission. Multivariate analysis identified immunocompromised status (p = 0.036; OR 3.5, 95% CI 1.1-11.5) and hepatic disease (chronic hepatitis or alcohol abuse) (p = 0.033; OR 2.9, 95% CI 1.1-7.7) as positive predictors of 90-day readmission. CONCLUSIONS The most common indication for readmission was persistent infection. Readmission was unrelated to baseline neurological status or management strategy. However, both hepatic disease and baseline immunosuppression significantly increased the odds of 90-day readmission after SEA treatment. Patients with these conditions may require closer follow-up upon discharge to reduce overall morbidity and hospital costs associated with SEA.

Abstract
BACKGROUND Red flags are signs and symptoms that are possible indicators of serious spinal pathology. There is limited evidence or guidance on how red flags should be used in practice. Due to the lack of robust evidence for many red flags their use has been questioned. The aim was to conduct a systematic review specifically reporting on studies that evaluated the diagnostic accuracy of red flags for Spinal Infection in patients with low back pain. METHODS Searches were carried out to identify the literature from inception to March 2019. The databases searched were Medline, CINHAL Plus, Web of Science, Embase, Cochrane, Pedro, OpenGrey and Grey Literature Report. Two reviewers screened article texts, one reviewer extracted data and details of each study, a second reviewer independently checked a random sample of the data extracted. RESULTS Forty papers met the eligibility criteria. A total of 2224 cases of spinal infection were identified, of which 1385 (62%) were men and 773 (38%) were women mean age of 55 (± 8) years. In total there were 46 items, 23 determinants and 23 clinical features. Spinal pain (72%) and fever (55%) were the most common clinical features, Diabetes (18%) and IV drug use (9%) were the most occurring determinants. MRI was the most used radiological test and Staphylococcus aureus (27%), Mycobacterium tuberculosis (12%) were the most common microorganisms detected in cases. CONCLUSION The current evidence surrounding red flags for spinal infection remains small, it was not possible to assess the diagnostic accuracy of red flags for spinal infection, as such, a descriptive review reporting the characteristics of those presenting with spinal infection was carried out. In our review, spinal infection was common in those who had conditions associated with immunosuppression. Additionally, the most frequently reported clinical feature was the classic triad of spinal pain, fever and neurological dysfunction.

Abstract
BACKGROUND CONTEXT Neutrophil to lymphocyte ratio and platelet to lymphocyte ratio have been previously identified as markers for overall survival in oncology but remain heretofore unexplored in spinal epidural abscess (SEA). PURPOSE The purpose of this study was to determine the impact of these routinely collected assessments on 90-day mortality in SEA. STUDY DESIGN/SETTING Retrospective, case-control study. PATIENT SAMPLE Patients 18 years or older diagnosed with SEA at 2 academic medical centers and 3 community hospitals. OUTCOME MEASURES Ninety-day postdischarge and in-hospital mortality. METHODS Complete blood count with differential obtained on the day immediately preceding or on the day of admission was used to calculate platelet to lymphocyte and neutrophil to lymphocyte ratios. Multivariate analyses were used to determine if these ratios were independent risk factors for 90-day mortality. RESULTS For 1,053 SEA patients included in the study, the rate of 90-day mortality was 134 (12.7%). The rate of 90-day mortality with neutrophil to lymphocyte ratio (≥8) was (20.5%) compared to (8.1%) with neutrophil to lymphocyte ratio <8. Neutrophil to lymphocyte ratio was positively associated with bacteremia, elevated erythrocyte sedimentation rate, and concurrent systemic infections (endocarditis, meningitis) and negatively associated with duration of symptoms prior to presentation. On multivariate analysis, elevated neutrophil to lymphocyte remained an independent risk factor for 90-day mortality (odds ratio=2.62, 95% confidence interval=1.66-4.17, p<.001). Platelet to lymphocyte ratio was not associated with 90-day mortality. CONCLUSIONS Absolute neutrophil to lymphocyte ratio is a routinely collected but overlooked biomarker in patients with spinal epidural abscess that is a novel independent risk factor for 90-day mortality.

Abstract
STUDY DESIGN Systematic review. OBJECTIVES Spinal epidural abscesses (SEAs) are rare, but when missed or when diagnosis is delayed, SEA can lead to permanent neurological impairment or death. Limited information exists on the optimal treatment modalities for SEA, especially in the lumbar spine. We synthesize the current literature to identify the clinical features, diagnosis, management, and outcomes of lumbar SEA. METHODS Queries in 4 databases-EMBASE, MEDLINE, Scopus, and Web of Science-were performed using comprehensive search terms to locate published literature on lumbar SEA. RESULTS Ten articles reporting results for 600 cases of lumbar SEA were included, published between 2000 and 2017. Negative prognostic factors included diabetes, older age, methicillin-resistant Staphylococcus aureus, immune compromise, and more severe disease at presentation. Early first-line surgically treated patients responded better, specifically in terms of motor recovery, than those undergoing medical management or failing medical treatment, despite generally worse initial presentation. Elevated C-reactive protein, leukocytosis, and positive blood cultures predicted medical management failure. CONCLUSIONS This systematic review provides guidance to neurological and orthopedic spine surgeons seeking the best treatment for lumbar-localized SEA. This study is limited by a dearth of high-quality publications to support evidenced-based management recommendations. Surgical treatment appears to provide better outcomes than medical treatment alone, especially in those who present with a motor deficit. Further investigation is needed to confirm this finding. What is clear is that early recognition and treatment remains crucial to minimizing morbidity and mortality of SEA.

Abstract
STUDY DESIGN Systematic review. OBJECTIVES Past research has demonstrated increased speed and severity of progression for spinal epidural abscesses (SEAs) of the thoracic level, specifically, when compared with SEAs of other spinal cord levels. Untreated, this infection can result in permanent neurological sequelae with eventual progression to death if inadequately managed. Despite the seriousness of this disease, no articles have focused on the presentation, diagnosis, and treatment of SEAs of the thoracic level. For this reason, specific focus on SEAs of the thoracic level occurred when researchers designed and implemented the following systematic review. METHODS A query of Ovid-Medline and EMBASE, Cochrane Central, and additional review sources was conducted. Search criteria focused on articles specific to thoracic epidural abscesses. RESULTS Twenty-five articles met inclusion criteria. The most commonly reported symptoms present on admission included back pain, paraparesis/paraplegia, fever, and loss of bowel/bladder control. Significant risk factors included diabetes, intravenous drug use, and advanced age (P = .001). Patients were most often treated surgically with either laminectomy, hemilaminectomy, or radical decompression with debridement. Patients who presented with neurological deficits and had delayed surgical intervention following a failed antibiotic course tended to do worse compared with their immediate surgical management counterparts (P < .005). CONCLUSIONS For the first time researchers have focused specifically on SEAs of the thoracic level, as opposed to previously published general analysis of SEAs as a whole. Based on the results, investigators recommend early magnetic resonance imaging of the spine, laboratory workup (sedimentation rate/C-reactive protein, complete blood count), abscess culture followed by empiric antibiotics, and immediate surgical decompression when neurological deficits are present.

Abstract
BACKGROUND Spinal epidural abscess is a high-risk condition that can lead to paralysis or death. It would be of clinical and prognostic utility to identify which subset of patients with spinal epidural abscess is likely to develop a motor deficit or die within 90 days of discharge. METHODS We identified all patients ≥18 years of age who were admitted to our hospital system with a diagnosis of spinal epidural abscess during the period of 1993 to 2016. Explanatory variables were collected retrospectively. Bivariate and multivariable logistic regression was performed using these variables to identify independent predictors of motor deficit and 90-day mortality. Nomograms were then constructed to quantify the risk of these outcomes. RESULTS Of the 1,053 patients we identified with spinal epidural abscess, 362 presented with motor weakness. One hundred and thirty-four patients died within 90 days of discharge, inclusive of those who died during hospitalization. Multivariable logistic regression yielded 8 independent predictors of pre-treatment motor deficit and 8 independent predictors of 90-day mortality. We constructed nomograms that generated a probability of pre-treatment motor deficit or 90-day mortality on the basis of the presence of these factors. CONCLUSIONS By quantifying the risk of pre-treatment motor deficit and 90-day mortality, our nomograms may provide useful prognostic information for the treatment team. Timely treatment of neurologically intact patients with a high risk of developing a motor deficit is necessary to avoid residual motor weakness and improve survival.

Abstract
BACKGROUND Prompt diagnosis and treatment are critical in spinal epidural abscess, as delay can lead to paralysis or death. The initial management decision for spinal epidural abscess is not always clear, with the literature showing conflicting results. When considering nonoperative management, it is crucial to avoid failure of treatment, given the neurologic compromise incurred through failure. Unfortunately, data regarding risk factors associated with failure are scarce. METHODS All patients admitted to our hospital system with a diagnosis of spinal epidural abscess from 1993 to 2016 were identified. Patients who were ≥18 years of age and were initially managed nonoperatively were included. Explanatory variables and outcomes were collected retrospectively. Bivariate and multivariable analyses were performed on these variables to identify independent predictors of failure of nonoperative treatment. A nomogram was constructed to generate a risk of failure based on these predictors. RESULTS We identified 367 patients who initially underwent nonoperative management. Of these, 99 patients underwent medical management that failed. Multivariable logistic regression yielded 6 independent predictors of failure: a presenting motor deficit, pathologic or compression fracture in affected levels, active malignancy, diabetes mellitus, sensory changes, and dorsal location of abscess. We constructed a nomogram that generates a probability of failure based on the presence of these factors. CONCLUSIONS By quantifying the risk of failure on the basis of the presence of 6 independent predictors of treatment failure, our nomogram may provide a useful tool for the treatment team when weighing the risks and benefits of initial nonoperative treatment compared with operative management. LEVEL OF EVIDENCE Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND Spontaneous spinal infections (SSIs) represent a rare and serious pathological entity. We tried to study a correlation between type of treatment, timing of treatment and clinical outcome through a multivariate analysis of an observational cohort study with the aim to define what is the optimal clinico-therapeutic management. METHODS We performed a retrospective observational cohort study on all consecutive patients observed in our Institute in a period of 13 years; from 2001 to 2014 we enrolled 50 consecutive patients with symptomatic spontaneous spinal infections (no previous surgery or recent infection in other site), confirmed with diagnostic imaging. The inclusion parameters were: diagnostic imaging, signs and symptoms positive for SSI, no history of recent infection or surgery. Of each parameter analyzed, we calculated mean and standard deviation and when necessary correlation (ρ), covariance (σ) and relation coefficient between type of treatment, timing of treatment and clinical outcome. RESULTS Our results suggest that an increase of one day from the onset of symptoms and the start of therapy leads to an increase in the Oswestry Disability Index Scale both at 6 months than at 1 year, with a statistical relevance, so our experience shows a statistically significant correlation and a positive co-variance between timing and outcome at 6 months and 1 year. CONCLUSIONS SSI are rare, very difficult to diagnose and represent a significant clinical problem. If not properly managed, they may lead to significant impact in the quality of life. The most relevant problem is not the treatment, conservative or surgical, but early diagnosis, so a careful physical, laboratory and imaging examination is fundamental, with an important help provided by isolation of the pathogen and histology. In our experience early diagnosis has a fundamental role. In the light of this, current treatment protocols may require a prompt and multidisciplinary management including infectivologists, neuroradiologists and spine surgeons.

Abstract
The epidural space contains the internal vertebral venous plexus, adipose, and other connective tissues. In the anatomical literature, there are nonspecific descriptions of varying fibrous connective tissue bands in the epidural space, mainly mentioned in the lumbar region, that tether the dural sac to the posterior longitudinal ligament, the vertebral canal, and the ligamentum flavum. These ligaments have been termed as Hofmann’s ligaments. This review expands on the anatomy and function of Hofmann’s ligaments, increasing the awareness of their presence and serves as an impetus for further study of their histology, innervation, and function.

Abstract
BACKGROUND A spinal epidural abscess is a medical emergency. Despite urgent surgical intervention and adjuvant antibiotic therapy, neurologic prognosis remains variable and guarded. The optimal approach to managing this condition is debated with substantial variability in clinical practice, dependent on patient demographic and pretreatment neurologic status as well as radiologic appearance. METHODS A systematic search in MEDLINE and similar databases was conducted for literature published from 1990 to 2015 using the search term "spinal epidural abscess", limiting the search results to human studies published in the English language. Case series that consisted of fewer than 10 patients were excluded. The evidence strength was graded according to the Grades of Recommendation Assessment, Development, and Evaluation criteria. RESULTS The search yielded 1843 patients from 34 retrospective case series. Ten studies compared surgical and medical management, with no significant difference in patients with good outcome (odds ratio, 0.65; P = 0.11) or neurologic improvement (odds ratio, 1.11; P = 0.69). However, failure rates after initial medical management requiring surgical intervention ranged from 10% to 50%. Three of 4 studies evaluating timing of surgery reported large effect sizes for neurologic outcome if early surgery was performed (P < 0.01). Other prognostic factors from a neurologic perspective included admission neurologic status, patient age, and diabetes mellitus. CONCLUSIONS Surgery with adjuvant antibiotics remains the optimal treatment for the neurologically symptomatic patient with spinal epidural abscess. If antibiotic therapy alone is considered for the neurologically intact patient, we recommend interdisciplinary medical and surgical consultations with an in-depth dialogue on the potential for failure in isolated medical management and the recommendation for close neurologic monitoring.

Abstract
Staphylococcus aureus is a major human pathogen that causes a wide range of clinical infections. It is a leading cause of bacteremia and infective endocarditis as well as osteoarticular, skin and soft tissue, pleuropulmonary, and device-related infections. This review comprehensively covers the epidemiology, pathophysiology, clinical manifestations, and management of each of these clinical entities. The past 2 decades have witnessed two clear shifts in the epidemiology of S. aureus infections: first, a growing number of health care-associated infections, particularly seen in infective endocarditis and prosthetic device infections, and second, an epidemic of community-associated skin and soft tissue infections driven by strains with certain virulence factors and resistance to β-lactam antibiotics. In reviewing the literature to support management strategies for these clinical manifestations, we also highlight the paucity of high-quality evidence for many key clinical questions.

Abstract
Study Design Case report. Objective To describe a very rare case of an immunocompetent man who underwent surgery for thoracic spondylodiscitis caused by methicillin-resistant Staphylococcus aureus (MRSA) that developed as a superinfection of a pulmonary tuberculous granuloma. Methods Posterior decompression and pedicle screw vertebral fixation were followed by T5-T6 anterior somatotomy with implant of an expandable mesh and lateral plating as symptoms worsened. During the anterior approach, an atypical resection of the left lower lobe was also performed. Results A tuberculous granuloma was detected on histology. Ziehl-Neelsen stain confirmed the diagnosis. Culture also detected MRSA. Conclusions Early medical management is the first choice for spondylodiscitis to eradicate the infection and alleviate pain. Immobilization of the affected spine segments can protect the patient from vertebral collapse and from the appearance of neurologic deficits. Surgery is suggested if there are compressive effects on the spinal cord, spinal epidural abscess, vertebral collapse, and deformity. We decided to remove the abscess and to restore the anterior column using an anterior approach. Moreover, in this case, an anterior approach allowed us to identify the etiology of the lesion and to determine the best chemotherapy regimen.

OBJECT Over the past decade, the incidence of bacterial spinal epidural abscess (SEA) has been increasing. In recent years, studies on this condition have been rampant in the literature. The authors present an 11-year institutional experience with SEA patients. Additionally, through an analysis of the contemporary literature, they provide an update on the challenging and controversial nature of this increasingly encountered condition. METHODS An electronic medical record database was used to retrospectively analyze patients admitted with SEA from January 2001 through February 2012. Presenting symptoms, concurrent conditions, microorganisms, diagnostic modalities, treatments, and outcomes were examined. For the literature search, PubMed was used as the search engine. Studies published from January 1, 2000, through December 31, 2013, were critically reviewed. Data from articles on methodology, demographics, treatments, and outcomes were recorded. RESULTS A total of 106 patients with bacterial SEA were identified. The mean ± SD age of patients was 63.3 ± 13.7 years, and 65.1% of patients were male. Common presenting signs and symptoms were back pain (47.1%) and focal neurological deficits (47.1%). Over 75% of SEAs were in the thoracolumbar spine, and over 50% were ventral. Approximately 34% had an infectious origin. Concurrent conditions included diabetes mellitus (35.8%), vascular conditions (31.3%), and renal insufficiency/dialysis (30.2%). The most commonly isolated organism was Staphylococcus aureus (70.7%), followed by Streptococcus spp. (6.6%). Surgery along with antibiotics was the treatment for 63 (59.4%) patients. Surgery involved spinal fusion for 19 (30.2%), discectomy for 14 (22.2%), and corpectomy for 9 (14.3%). Outcomes were reported objectively; at a mean ± SD follow-up time of 8.4 ± 26 weeks (range 0-192 weeks), outcome was good for 60.7% of patients and poor for 39.3%. The literature search yielded 40 articles, and the authors discuss the result of these studies. CONCLUSIONS Bacterial SEA is an ominous condition that calls for early recognition. Neurological status at the time of presentation is a key factor in decision making and patient outcome. In recent years, surgical treatment has been advocated for patients with neurological deficits and failed response to medical therapy. Surgery should be performed immediately and before 36-72 hours from onset of neurological sequelae. However, the decision between medical or surgical intervention entails individual patient considerations including age, concurrent conditions, and objective findings. An evidence-based algorithm for diagnosis and treatment is suggested.

Abstract
OBJECT One often overlooked aspect of spinal epidural abscesses (SEAs) is the timing of surgical management. Limited evidence is available correlating earlier intervention with outcomes. Spinal epidural abscesses, once a rare diagnosis carrying a poor prognosis, are steadily becoming more common, with one recent inpatient meta-analysis citing an approximate incidence of 1 in 10,000 admissions with a mortality approaching 16%. One key issue of contention is the benefit of rapid surgical management of SEA to maximize outcomes. Timing of surgical management is definitely one overlooked aspect of care in spinal infections. Therefore, the authors performed a retrospective analysis in which they evaluated patients who underwent early (evacuation within 24 hours) versus delayed surgical intervention (> 24 hours) from the point of diagnosis, in an attempt to test the hypothesis that earlier surgery results in improved outcomes. METHODS A retrospective review of a prospectively maintained adult neurosurgical database from 2009 to 2011 was conducted for patients with the diagnostic heading: epidural abscess, infection, osteomyelitis, osteodiscitis, spondylodiscitis, and abscess. The primary end point for each patient was neurological grade, measured as an American Spinal Injury Association Impairment Scale grade using hospital inpatient records on admission and discharge. Patients were divided into early surgical (< 24 hours) and delayed surgical cohorts. RESULTS Eighty-seven consecutive patients were identified (25 females; mean age 55.5 years, age range 18-87 years). Fifty-four patients received surgery within 24 hours of admission (mean time from admission to incision, 11.2 hours), and 33 underwent surgery longer than 24 hours (mean 59 hours) after admission. Of the 54 patients undergoing early surgery 45 (85%) had a neurological deficit, whereas in the delayed surgical group 21 (64%) of 33 patients presented with a neurological deficit (p = 0.09). Patients in the delayed surgery cohort were significantly older by 10 years (59.6 vs 51.8 years, p = 0.01). With regard to history of prior revision, body mass index, intravenous drug abuse, tobacco use, prior radiation therapy, diabetes, chronic systemic infection, and prior osteomyelitis, there were no significant differences. There was no significant difference between early and delayed surgery groups in neurological grade on presentation, discharge, or location of epidural abscess. The most common organism isolated was Staphylococcus aureus (n = 51, 59.3%). The incidence of methicillin-resistant S. aureus was 21% (18 of 87). CONCLUSIONS Evacuation within 24 hours appeared to have a relative advantage over delayed surgery with regard to discharge neurological grade. However, due to a limited, variable sample size, a significant benefit could not be shown. Further subgroup analyses with larger populations are required.

Abstract
BACKGROUND CONTEXT The treatment of epidural abscess is known to have a high rate of morbidity. Little is known regarding the risk factors for postoperative complications, mortality, and costs of care. PURPOSE To identify predictors of postsurgical morbidity and mortality, and total charges, associated with epidural abscess. STUDY DESIGN Nationwide Inpatient Sample (NIS) from the year 2006 to 2011. PATIENT SAMPLE All patients who had epidural abscess and underwent surgery in the NIS were included. Weighting was used to derive a representative sample. OUTCOME MEASURES They included in-hospital mortality, the development of complications, and total charges. A utility for failure to rescue (FTR) was also developed. Failure to rescue was defined as occurring when patients died after sustaining a complication. METHODS All patients identified as having epidural abscess and receiving surgical intervention were included. Risk factors were assessed in a bivariate fashion with those maintaining p values less than .2 included in the final multivariable models. Independent predictors of outcome were those that maintained significance after inclusion in multivariable regression. Predictors for total charges were evaluated using generalized linear modeling. RESULTS The population consisted of 30, 274 individuals. The mean age was 57.4 years (±14.7 years). Sixty-three percent of the population was white and 27% was underinsured. Diabetes was present in 30% and 19% had some degree of paralysis. Three percent of patients died during hospitalization and 26% sustained one or more complications. Mean total charges were $159,782 (range: $4,008-$3,373,410). Significant independent predictors for mortality included age, insurance status, liver disease, paralysis, and renal failure, with age (80 years or more) having the greatest effect (odds ratio 4.0 [95% confidence interval 2.0, 7.9]). Many of these same variables were found to be influential in the development of postoperative complications, major morbidity, and FTR. The number of medical comorbidities, underinsured status, paralysis, and renal failure were factors that influenced charges to an extent greater than 20% of the population mean. CONCLUSIONS Age, insurance status, paralysis, and medical comorbidities appear to be the predictors of morbidity, mortality, and expense of care. The results of this work highlight the characteristics that may be targeted to reduce charges and improve care for epidural abscess.

Abstract
Furunculosis is a deep infection of the hair follicle leading to abscess formation with accumulation of pus and necrotic tissue. Furuncles appear as red, swollen, and tender nodules on hair-bearing parts of the body, and the most common infectious agent is Staphylococcus aureus, but other bacteria may also be causative. In some countries, methicillin resistant S. aureus is the most common pathogen in skin and soft tissue infections which is problematic since treatment is difficult. Furunculosis often tends to be recurrent and may spread among family members. Some patients are carriers of S. aureus and eradication should be considered in recurrent cases. Solitary lesions should be incised when fluctuant, whereas patients with multiple lesions or signs of systemic disease or immunosuppression should be treated with relevant antibiotics. The diagnostic and therapeutic approach to a patient suspected of staphylococcosis should include a thorough medical history, clinical examination, and specific microbiological and biochemical investigations. This is particularly important in recurrent cases where culture swabs from the patient, family members, and close contacts are mandatory to identify and ultimately control the chain of infection. Focus on personal, interpersonal, and environmental hygiene issues is crucial to reduce the risk of contamination and recurrences.

Abstract
BACKGROUND CONTEXT Spinal epidural abscess (SEA) is a rare, serious and increasingly frequent diagnosis. Ideal management (medical vs. surgical) remains controversial. PURPOSE The purpose of this study is to assess the impact of risk factors, organisms, location and extent of SEA on neurologic outcome after medical management or surgery in combination with medical management. STUDY DESIGN Retrospective electronic medical record (EMR) review. PATIENT SAMPLE We included 128 consecutive, spontaneous SEA from a single tertiary medical center, from January 2005 to September 11. There were 79 male and 49 female with a mean age of 52.9 years (range, 22-83). OUTCOME MEASURES Patient demographics, presenting complaints, radiographic features, pre/post-treatment neurologic status (ASIA motor score [MS] 0-100), treatment (medical vs. surgical) and clinical follow-up were recorded. Neurologic status was determined before treatment and at last available clinical encounter. Imaging studies reviewed location/extent of pathology. METHODS Inclusion criteria were a diagnosis of a bacterial SEA based on radiographs and/or intraoperative findings, age greater than 18 years, and adequate EMR. Exclusion criteria were postinterventional infections, Pott's disease, isolated discitis/osteomyelitis, treatment initiated at an outside facility, and imaging suggestive of a SEA but negative intraoperative findings/cultures. RESULTS The mean follow-up was 241 days. The presenting chief complaint was site-specific pain (100%), subjective fevers (50%), and weakness (47%). In this cohort, 54.7% had lumbar, 39.1% thoracic, 35.9% cervical, and 23.4% sacral involvement spanning an average of 3.85 disc levels. There were 36% ventral, 41% dorsal, and 23% circumferential infections. Risk factors included a history of IV drug abuse (39.1%), diabetes mellitus (21.9%), and no risk factors (22.7%). Pathogens were methicillin-sensitive Staphylococcus aureus (40%) and methicillin-resistance S aureus (30%). Location, SEA extent, and pathogen did not impact MS recovery. Fifty-one patients were treated with antibiotics alone (group 1), 77 with surgery and antibiotics (group 2). Within group 1, 21 patients (41%) failed medical management (progressive MS loss or worsening pain) requiring delayed surgery (group 3). Irrespective of treatment, MS improved by 3.37 points. Thirty patients had successful medical management (MS: pretreatment, 96.5; post-treatment, 96.8). Twenty-one patients failed medical therapy (41%; MS: pretreatment, 99.86, decreasing to 76.2 [mean change, -23.67 points], postoperative improvement to 85.0; net deterioration, -14.86 points). This is significantly worse than the mean improvement of immediate surgery (group 2; MS: pretreatment, 80.32; post-treatment, 89.84; recovery, 9.52 points). Diabetes mellitus, C-reactive protein greater than 115, white blood count greater than 12.5, and positive blood cultures predict medical failure: None of four parameters, 8.3% failure; one parameter, 35.4% failure; two parameters, 40.2% failure; and three or more parameters, 76.9% failure. CONCLUSION Early surgery improves neurologic outcomes compared with surgical treatment delayed by a trial of medical management. More than 41% of patients treated medically failed management and required surgical decompression. Diabetes, C-reactive protein greater than 115, white blood count greater than 12.5, and bacteremia predict failure of medical management. If a SEA is to be treated medically, great caution and vigilance must be maintained. Otherwise, early surgical decompression, irrigation, and debridement should be the mainstay of treatment.

Abstract
PURPOSE OF REVIEW The incidence of spinal epidural abscess is increasing, and the understanding of the pathophysiology is evolving. Better understanding of the pathophysiology, specifically the role of ischemia, warrants a change in therapy. RECENT FINDINGS Paralysis in spinal epidural abscess may be the result of spinal cord compression, spinal cord arterial and/or venous ischemia and thrombophlebitis or a combination of these. SUMMARY Recent evidence indicates the following areas of investigation and management can improve outcome in spinal epidural abscess: minimally invasive surgery early versus medical management when there are no significant neurological deficits, neuroradiologic arterial evaluation with therapies directed at vascular ischemia and thrombosis, and aggressive rehabilitation.

Abstract
Spinal epidural abscess (SEA) is a severe pyogenic infection of the epidural space that leads to devastating neurological deficits and may be fatal. SEA is usually located in the thoracic and lumbar parts of the vertebral column and injures the spine by direct compression or local ischemia. Spinal injury may be prevented if surgical and medical interventions are implemented early. The diagnosis is difficult, because clinical symptoms are not specific and can mimic many benign conditions. The classical triad of symptoms includes back pain, fever and neurological deterioration. The gold standard in the diagnostic evaluation is magnetic resonance imaging with gadolinium enhancement, which determines the location and extent of the abscess. Increased awareness of the disease is essential for rapid recognition and immediate implementation of treatment. Here we describe the case of a 26-year-old woman with SEA with fever, back pain in the thoracic region and delayed symptoms of a transverse spinal cord injury.

Abstract
Object
Spinal epidural abscess (SEA), once considered a rare occurrence, has showed a rapid increase in incidence over the past 20–30 years. Recent reports have advocated for conservative, nonoperative management of this devastating disorder with appropriate risk stratification. Crucial to a successful management strategy are decisive diagnosis, prompt intervention, and consistent follow-up care. The authors present a review of their institutional experience with operative and nonoperative management of SEA to assess morbidity and mortality and the accuracy of microbiological diagnosis.
Methods
A retrospective analysis of patient charts, microbiology reports, operative records, and radiology reports was performed on all cases involving patients admitted with the diagnosis of SEA between July 1998 and May 2009.
Results
Seventy-seven cases were reviewed (median patient age 51.4 years, range 17–78 years). Axial pain was the most common presenting symptom (67.5% of cases). Presenting signs included focal weakness (55.8%), radiculopathy (28.6%), and myelopathy (5.2%). Abscesses were localized to the lumbar, thoracic, and cervical spine, respectively, in 39 (50.6%), 20 (26.0%), and 18 (23.4%) of the patients. Peripheral blood cultures were negative in 32 (45.1%) of 71 patients. Surgical site or interventional biopsy cultures were diagnostic in 52 cases (78.8%), with concordant blood culture results in 36 (60.0%). Methicillin-resistant Staphylococcus aureus (MRSA) was the most frequent isolate in 24 cases (31.2%). The mean time from admission to surgery was 5.5 days (range 0–42 days; within 72 hours in 66.7% of cases). Outcome data were available in 72 cases. At discharge, patient condition had improved or resolved in 57 cases (79.2%), improved minimally in 6 (8.3%), and showed no improvement or worsening in 9 (12.5%). Patient age and premorbid weakness were the only factors found to be significantly associated with outcome (p = 0.04 and 0.012, respectively).
Conclusions
These results strongly support immediate surgical decompression combined with appropriately tailored antibiotic therapy for the treatment of symptomatic SEA presenting with focal neurological deficit. The nonsuperiority discovered in other patient subsets may be due to allocation biases between surgically treated and nonsurgically treated cohorts. The present data demonstrate the accuracy of peripheral blood culture for the prediction of causative organisms and confirm patient age as a predictor of outcomes.

Abstract
The causative organism of vertebral osteomyelitis (VO) was almost exclusively Staphylococcus aureus. The purpose of this study was to delineate the differences in clinical features and outcomes between patients with methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) VO. This study retrospectively reviewed 85 consecutive patients with VO treated between 2005 and 2011. Surgical site infections were excluded. Diagnosis was made by cultures of either blood or biopsied samples. We identified 16 cases of MRSA VO and 14 cases of MSSA VO. The average follow-up period was 18.5 months. Clinical features and outcomes were analyzed. Males were more likely to have MRSA VO than MSSA VO (87.5% vs. 35.7%). In regards to the number of co-morbidities, patients with MRSA VO had significantly more co-mobidities than patients with MSSA VO. Additionally, the rate of patients who underwent surgical procedure (excluding spinal surgeries in the affected region) within 3 months were significantly higher in the MRSA VO group than the MSSA VO group (56.3% vs. 14.3%). White blood cell counts and C-reactive protein levels in patients with both strains significantly improved 4 weeks after the initial treatment compared with the pretreatment values. The recurrence rate within 6 months tended to be higher for MRSA VO (37.5% vs. 7.1%), but no significant difference in mortality was observed between the two VO types. In conclusion, male sex, multiple co-morbidities and previous non-spine surgery were significant risk factors for VO due to MRSA as compared to MSSA. The recurrence rate within 6 months tended to be higher for MRSA VO. Patients with MRSA VO should be monitored carefully for recurrence by sequential clinical, radiographic, and laboratory examinations during the treatment course.

Abstract
INTRODUCTION Spinal infection is a rare pathology although a concerning rising incidence has been observed in recent years. This increase might reflect a progressively more susceptible population but also the availability of increased diagnostic accuracy. Yet, even with improved diagnosis tools and procedures, the delay in diagnosis remains an important issue. This review aims to highlight the importance of a methodological attitude towards accurate and prompt diagnosis using an algorithm to aid on spinal infection management. METHODS Appropriate literature on spinal infection was selected using databases from the US National Library of Medicine and the National Institutes of Health. RESULTS Literature reveals that histopathological analysis of infected tissues is a paramount for diagnosis and must be performed routinely. Antibiotic therapy is transversal to both conservative and surgical approaches and must be initiated after etiological diagnosis. Indications for surgical treatment include neurological deficits or sepsis, spine instability and/or deformity, presence of epidural abscess and upon failure of conservative treatment. CONCLUSIONS A methodological assessment could lead to diagnosis effectiveness of spinal infection. Towards this, we present a management algorithm based on literature findings.

Abstract
Central nervous system (CNS) infections—i.e., infections involving the brain (cerebrum and cerebellum), spinal cord, optic nerves, and their covering membranes—are medical emergencies that are associated with substantial morbidity, mortality, or long-term sequelae that may have catastrophic implications for the quality of life of affected individuals. Acute CNS infections that warrant neurointensive care (ICU) admission fall broadly into three categories—meningitis, encephalitis, and abscesses—and generally result from blood-borne spread of the respective microorganisms. Other causes of CNS infections include head trauma resulting in fractures at the base of the skull or the cribriform plate that can lead to an opening between the CNS and the sinuses, mastoid, the middle ear, or the nasopharynx. Extrinsic contamination of the CNS can occur intraoperatively during neurosurgical procedures. Also, implanted medical devices or adjunct hardware (e.g., shunts, ventriculostomies, or external drainage tubes) and congenital malformations (e.g., spina bifida or sinus tracts) can become colonized and serve as sources or foci of infection. Viruses, such as rabies, herpes simplex virus, or polioviruses, can spread to the CNS via intraneural pathways resulting in encephalitis. If infection occurs at sites (e.g., middle ear or mastoid) contiguous with the CNS, infection may spread directly into the CNS causing brain abscesses; alternatively, the organism may reach the CNS indirectly via venous drainage or the sheaths of cranial and spinal nerves. Abscesses also may become localized in the subdural or epidural spaces. Meningitis results if bacteria spread directly from an abscess to the subarachnoid space. CNS abscesses may be a result of pyogenic meningitis or from septic emboli associated with endocarditis, lung abscess, or other serious purulent infections. Breaches of the blood–brain barrier (BBB) can result in CNS infections. Causes of such breaches include damage (e.g., microhemorrhage or necrosis of surrounding tissue) to the BBB; mechanical obstruction of microvessels by parasitized red blood cells, leukocytes, or platelets; overproduction of cytokines that degrade tight junction proteins; or microbe-specific interactions with the BBB that facilitate transcellular passage of the microorganism. The microorganisms that cause CNS infections include a wide range of bacteria, mycobacteria, yeasts, fungi, viruses, spirochaetes (e.g., neurosyphilis), and parasites (e.g., cerebral malaria and strongyloidiasis). The clinical picture of the various infections can be nonspecific or characterized by distinct, recognizable clinical syndromes. At some juncture, individuals with severe acute CNS infections require critical care management that warrants neuro-ICU admission. The implications for CNS infections are serious and complex and include the increased human and material resources necessary to manage very sick patients, the difficulties in triaging patients with vague or mild symptoms, and ascertaining the precise cause and degree of CNS involvement at the time of admission to the neuro-ICU. This chapter addresses a wide range of severe CNS infections that are better managed in the neuro-ICU. Topics covered include the medical epidemiology of the respective CNS infection; discussions of the relevant neuroanatomy and blood supply (essential for understanding the pathogenesis of CNS infections) and pathophysiology; symptoms and signs; diagnostic procedures, including essential neuroimaging studies; therapeutic options, including empirical therapy where indicated; and the perennial issue of the utility and effectiveness of steroid therapy for certain CNS infections. Finally, therapeutic options and alternatives are discussed, including the choices of antimicrobial agents best able to cross the BBB, supportive therapy, and prognosis.

Insidious Onset of Tetraparesis due to Cervical Epidural Abscess from Enterococcus faecalis. Case Rep Med 2013; 2013:513920.

Abstract
We report a case of cervical epidural abscess from Enterococcus faecalis, which caused an insidious onset of tetraparesis. This 53-year-old female with a history of diabetes mellitus and chronic renal failure under hemodialysis presented with pain and progressive weakness of upper and lower extremities without fever. Although a recent MRI she did at the beginning of symptoms showed no significant pathologies, except for a cervical disc herniation and adjacent spinal degeneration, and stenosis that confused the diagnostic procedure, newer imaging with CT and MRI, which was performed due to progression of tetraparesis, revealed the formation of a cervical epidural abscess. Surgical drainage was done after a complete infection workup. The patient showed immediate neurological improvement after surgery. She received antibiotics intravenously for 3 weeks and orally for another 6 weeks. The patient was free from complications 24 months after surgery. A high index of suspicion is most important in making a rapid and correct diagnosis of spinal epidural abscess. The classic clinical triad (fever, local pain, and neurologic deficits) is not sensitive enough for early detection. Continuous clinical, laboratory, and imaging monitoring are of paramount importance. Early diagnosis and surgical intervention could optimize the final functional outcome.

Abstract
Background: We reviewed the literature regarding the pathogenesis, clinical presentation, diagnosis, and management of spinal epidural abscess (SEA). Methods: Utilizing PubMed, we performed a comprehensive review of the literature on SEAs. Results: SEA remains a difficult infectious process to diagnose. This is particularly true in the early stages, when patients remain neurologically intact, and before the classic triad of fever, back pain, and neurologic deficit develop. However, knowledge of risk factors, obtaining serologic markers, and employing magnetic resonance scans facilitate obtaining a prompt and accurate diagnosis. In patients without neurologic deficits, lone medical therapy may prove effective. Conclusions: More prevalent over the previous three decades, SEA remains a rare but deleterious infectious process requiring prompt identification and treatment. Historically, identification of SEA is often elusive, diagnosis is delayed, and clinicians contend that surgical debridement is the cornerstone of treatment. Early surgery leads to more favorable outcomes and preserves neurologic function, particularly in the early stages of disease when minimal or no neurologic deficits are present. The advent of improved imaging modalities, diagnostic techniques, and multidrug antimicrobial agents has enabled medical/spinal surgical consultants to more rapidly diagnose SEA and institute more effective early medical treatment (e.g., data suggest that lone medical therapy may prove effective in the early management of SEA).

Abstract
A 62-year-old woman presented with a 4-month history of central lower backache and a 2-week history of progressive bilateral leg weakness. She also complained of numbness on her left thigh and gluteal region, associated with urinary hesitancy and constipation. On examination, she had bilateral partial foot drop, absent knee and ankle reflexes and a negative Babinski's reflex and associated hyperaesthesia in L3 distribution bilaterally with decreased anal tone. Laboratory results revealed normal inflammatory markers. MRI scan demonstrated a large uniformly enhancing lesion in the filum terminale suggestive of a lumbar spinal tumour. An emergency spinal laminectomy from L3 to S2 was performed. Per operatively, the duramater was thickened and hyperaemic. The histopathology report suggested inflammation with no evidence of malignancy. Tissue specimen of cultured Staphylococcus aureus was sensitive to flucloxacillin. A final diagnosis of lumbar spinal abscess was made and subsequent antibiotic treatment led to good clinical recovery.
