Abstract
Spinal infections are relatively rare entities but the incidence is significantly increasing due to the rapidly growing numbers of interventions on the spine. Primary infections of intervertebral discs (spondylodiscitis) and vertebral bodies (spondylitis) are distinguished from secondary postinterventional infections. Treatment relies primarily on either conservative or surgical management. In the absence of indications for surgery, a conservative approach is indicated when the patient is neurologically intact and the bony destruction is minimal. Conservative therapeutic options are based on the microbiological diagnosis and use of antibiotics, immobilization, analgesics and orthotics. Indications for a surgical intervention are the presence of neurological deficits, intraspinal abscesses, extensive osseous destruction and failure of conservative management. Surgical therapy focusses on the decompression of neural structures, debridement and eradication of the focus of infection, pathogen identification, correction of the deformity and restoration of a physiological spinal profile. Following a postoperative infection a timely diagnosis including assessment of the extent of infection is crucial. In the case of a purely superficial infection, antibiotic prophylaxis and close monitoring is indicated. If findings are pronounced surgical revision, debridement together with antibiotic therapy and if necessary vacuum-assisted closure as well as revision ranging from exchange of implants to complete removal of osteosynthetic material are required. Spinal infections are severe conditions frequently with residual long-term sequelae, whether the patients are managed conservatively or surgically.

Abstract
BACKGROUND Back pain has many causes. In Germany, about 70% of adults have at least one episode of back pain per year. METHODS This review is based on a selective literature search and on the German National Disease Management Guideline for Low Back Pain. RESULTS The physician taking the history from a patient with back pain should ask about the nature, onset, course, localization, and radiation of the pain and its dependence on physical activity and/or emotional stress. In the differential diagnosis, neurologic deficits and any "red flags" suggesting dangerous conditions such as spinal fracture, bacterial infection, and tumors must be ruled out. If no specific cause of the pain can be identified, no imaging studies are indicated on initial presentation. The treatment of acute, nonspecific low back pain focuses on pain relief and functional improvement. Adequate patient education and counseling are essential. Exercise therapy is no more effective than the continuation of normal daily activities. Restriction of activity, including bed rest, is of no benefit and merely prolongs recovery and the resumption of normal activity. Further diagnostic testing is indicated if there is any suspicion of a fracture, infection, or tumor. CONCLUSION After dangerous conditions have been ruled out, low back pain can be pragmatically classified as either nonspecific or specific. More research is needed so that the diagnostic assessment and individualized treatment of acute lower back pain can be further refined.

Abstract
Streptococcus constellatus is an extremely rare cause of pyogenic spondylodiscitis. Literature search yielded only one case report in an elderly 72 years old man with spontaneous T10-T11 S. constellatus spondylodiscitis. It is virtually unheard of in young teenage. We report the case of a 14 years old male teenager who presented with worsening low back pain for one year with no neurological deficit. Imaging studies were consistent with features of L4-L5 spondylodiscitis. CT guided biopsy grew a pure culture of streptococcus constellatus sensitive to penicillin and erythromycin. He showed full recovery with six weeks of intravenous antibiotics. Due to the insidious onset, this case highlight the importance of high clinical suspicion and early diagnosis, with image guided biopsy followed by treatment with appropriate intravenous antibiotics to enable full recovery without further neurological deterioration.

Abstract
BACKGROUND A recent population-based study from Denmark showed that the incidence of spondylodiscitis rose from 2.2 to 5.8 per 100 000 persons per year over the period 1995-2008; the age-standardized incidence in Germany has been estimated at 30 per 250 000 per year on the basis of data from the Federal Statistical Office (2015). The early diagnosis and treatment of this condition are essential to give the patient the best chance of a good outcome, but these are often delayed because it tends to present with nonspecific manifestations, and fever is often absent. METHODS This article is based on a systematic search of Medline and the Cochrane Library for the period January 2009 to March 2017. Of the 788 articles identified, 30 publications were considered. RESULTS The goals of treatment for spondylodiscitis are to eliminate infection, restore functionality of the spine, and relieve pain. Magnetic resonance imaging (MRI) remains the gold standard for the radiological demonstration of this condition, with 92% sensitivity and 96% specificity. It also enables visualization of the spatial extent of the infection and of abscess formation (if present). The most common bacterial cause of spondylodiscitis in Europe is Staphylococcus aureus, but tuberculous spondylodiscitis is the most common type worldwide. Antibiotic therapy is a pillar of treatment for spondylodiscitis and should be a part of the treatment in all cases. Neurologic deficits, sepsis, an intraspinal empyema, the failure of conservative treatment, and spinal instability are all indications for surgical treatment. CONCLUSION The quality of life of patients who have been appropriately treated for spondylodiscitis has been found to be highly satisfactory in general, although back pain often persists. The risk of recurrence increases in the presence of accompanying illnesses such as diabetes mellitus, renal failure, or undrained epidural abscesses.

Abstract
Spondylodiscitis may involve the vertebral bodies, intervertebral discs, paravertebral structures and spinal canal, with potentially high morbidity and mortality rates. A rise in the susceptible population and improved diagnosis have increased the reported incidence of the disease in recent years. Blood cultures, appropriate imaging and biopsy are essential for diagnosis and treatment. Most patients are successfully treated by conservative means; however, some patients may require surgical treatment. Surgical indications include doubtful diagnosis, progressive neurological deficits, progressive spinal deformity, failure to respond to treatment, and unresolved pain.

Abstract
Spondylodiscitis is a severe infectious disease of the intervertebral discs and of the adjacent parts of the vertebral bodies, culminating in destruction of the mobile segment. It is accompanied by a mortality rate of approximately 15%. Severe courses of the disease can also lead to abscess formation and dispersal of sepsis. Malpositioning of the axis organ and deficits in neurological function up to paraplegia are also possible complications. Timely diagnostics and targeted therapy contribute to minimizing the risk of significant health disorders. This review article gives a summary of important algorithms in the diagnostics and treatment and discusses them against the background of currently available literature. According to the current state of knowledge the surgical treatment of spondylodiscitis provides many advantages and is therefore the method choice, even if a conservative approach can be successful in selected cases. The endpoints of treatment are cleansing of the infection with normalization of laboratory parameters of inflammation and the osseous fusion of the mobile segment.

Early surgery with antibiotics treatment had better clinical outcomes than antibiotics treatment alone in patients with pyogenic spondylodiscitis: a retrospective cohort study. BMC Musculoskelet Disord 2017; 18:175. [PMID: 28449655 PMCID: PMC5408454 DOI: 10.1186/s12891-017-1533-1] [Citation(s) in RCA: 45] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2016] [Accepted: 04/21/2017] [Indexed: 11/22/2022] Open
Abstract
Background Pyogenic spondylodiscitis is a form of spinal infection that can result in severe back pain and even death. However, information is lacking on the relative effectiveness of various therapies. A retrospective chart review was conducted to investigate whether early surgical treatment of pyogenic spondylodiscitis coupled with intravenous antibiotics results in better patient prognoses than intravenous antibiotics therapy alone. Methods All patients treated for pyogenic spondylodiscitis at a single medical center from July 2006 to July 2011 were retrospectively reviewed. The inclusion criteria consisted of diagnosis of an early stage infection without neurological deficit, and patients without severe sepsis who were suitable candidates for early surgery as determined by a Pittsburgh bacteremia score < 4, and patients with delayed diagnosis and lost to outpatient follow-up were excluded. Clinical outcomes included patient demographic data, kyphosis angle, length of treatment, Oswestry Disability Index and visual analogue pain scale were analyzed. Results Of 90 enrolled patients, Group 1 (n = 47) received only antibiotic therapy and Group 2 (n = 43) received early surgery with post-surgery antibiotics for 2 to 4 weeks. Group 2 exhibited significantly better results than Group 1 for mean antibiotic administration period, mean hospitalization period, kyphotic angle correction. Of 61 patients who participated in telephone follow-up after discharge, Group 2 (n = 26) had significant lower mean ODI score, and mean back pain score than Group 1 (n = 35). Conclusions While infection control was similar for both groups, patients treated with early surgery and antibiotics were hospitalized for fewer days and required less antibiotics than those treated with antibiotics alone, also having better functional outcomes. In short, early surgical treatment of pyogenic spondylodiscitis typically achieves a better prognosis, shorter hospitalization period, and subsequent significant improvement in kyphotic deformity and quality of life.

Abstract
Pyogenic spinal infection continues to represent a worldwide problem. In approximately one-third of patients with pyogenic spondylodiscitis, the infectious agent is never identified. Of the cases that lead to organismal identification, bacteria are more commonly isolated from the spine rather than fungi and parasites. This study applied universal prokaryotic 16S rRNA PCR as a rapid diagnostic tool for the detection of bacterial agents in specimens from patients suspected of pyogenic spondylodiscitis. Gram and Ziehl-Neelsen staining were used as a preliminary screening measure for microbiologic evaluation of patient samples. PCR amplification targeting 16S rRNA gene was performed on DNA extracted from 57 cases including specimens from epidural abscesses, vertebral, and disc biopsies. Positive samples were directly sequenced. MRI findings demonstrated that disc destruction and inflammation were the major imaging features of suspected pyogenic spondylodiscitis cases, as 44 cases showed such features. The most common site of infection was the lumbar spine (66.7%), followed by thoracic spine (19%), the sacroiliac joint (9.5%), and lumbar-thoracic spine (4.8%) regions. A total of 21 samples amplified the 16S rRNA-PCR product. Sanger sequencing of the PCR products identified the following bacteriological agents: Mycobacterium tuberculosis (n = 9; 42.9%), Staphylococcus aureus (n = 6; 28.5%), Mycobacterium abscessus (n = 5; 23.8%), and Mycobacterium chelonae (n = 1; 4.8%). 36 samples displayed no visible 16S rRNA PCR signal, which suggested that non-bacterial infectious agents (e.g., fungi) or non-infectious processes (e.g., inflammatory, or neoplastic) may be responsible for some of these cases. The L3–L4 site (23.8%) was the most frequent site of infection. Single disc/vertebral infection were observed in 9 patients (42.85%), while 12 patients (57.15%) had 2 infected adjacent vertebrae. Elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) inflammatory markers were noted in majority of the patients. In conclusion, microbiological methods and MRI findings are vital components for the proper diagnosis of pyogenic spondylodiscitis. Our findings suggest that molecular methods such as clinical application of 16S rRNA PCR and sequencing may be useful as adjunctive diagnostic tools for pyogenic spondylodiscitis. The rapid turnaround time of 16S rRNA PCR and sequencing submission and results can potentially decrease the time to diagnosis and improve the therapeutic management and outcome of these infections. Although S. aureus and M. tuberculosis were the most common causes of pyogenic spinal infections in this study, other infectious agents and non-infectious etiologies should be considered. Based on study results, we advise that antibiotic therapy should be initiated after a definitive etiological diagnosis.

Abstract
All over the globe, the incidence of vertebral infection is rising. Nowadays, compared to tuberculous variety, pyogenic spondylodiscitis incidence is high. The increase in the susceptible population and improved diagnostics summatively contributed to this. In clinical grounds, differentiation of pyogenic and tuberculous spondylodiscitis is well defined. Enterobacter agglomerans is a hospital contaminant and associated with infections in immunocompromised individuals and intravenous lines. It causes a wide array of infections. Enterobacter agglomerans spondylodiscitis is unusual and there are, around the globe, only less than 31 suspected cases that have been previously reported. Enterobacter agglomerans histology mimics tuberculous rather than pyogenic spondylodiscitis. A 65-year-old farming lady, while being in hospital, developed sudden onset spastic paraparesis with hyperreflexia. Later blood culture revealed Enterobacter agglomerans with 41-hour incubation in 99.9% probability from Ramel identification system. Her initial ESR was 120 mm/first hour. Isolate was susceptible to ciprofloxacin and intravenous followed with oral therapy shows a drastic ESR fall and improved clinical response. Differentiation of tuberculous and pyogenic spondylodiscitis is very much important in management point of view. Therefore, blood culture has a role in diagnosis of spondylodiscitis. ESR can be used as important inflammatory marker in monitoring the response to treatment. Retrospectively, ESR would aid in reaching a definitive diagnosis.

Abstract
Infective spondylodiscitis is a rare disease. This case review describes the clinical course, risk factors, and outcomes of adult patients on maintenance hemodialysis who presented with infective spondylodiscitis at a single medical center in Taiwan. There were 18 cases (mean age: 64.9 ± 10.8 years) over more than 10 years. Analysis of underlying diseases indicated that 50% of patients had diabetes, 55.6% had hypertension, 55.6% had coronary artery disease, 22.2% had congestive heart failure, 22.2% had a cerebral vascular accident, 16.7% had liver cirrhosis, and 11.1% had malignancies. Sixty-one percent of patients had a degenerative spinal disease and the most common symptom was back pain (83.3%). A total of 38.9% of patients had leukocytosis, 99.4% had elevated levels of C-reactive protein, 78.6% had elevated erythrocyte sedimentation rates, and 55.6% had elevated levels of alkaline phosphatase. The average hemodialysis duration was 72.8 ± 87.5 months, and 8 patients (44.4%) started hemodialysis within 1 year prior to infective spondylodiscitis. Four patients (22.2%) had vascular access infection-associated spondylodiscitis. The lumbar region was the most common location of infection (77.8%), 44.4% of patients developed abscesses, and Staphylococci were the most common pathogen (38.9%). The mortality rate was 16.7%, all due to sepsis. Thirty-three percent of the survivors had recurrent infective spondylodiscitis within 1 year. Infective spondylodiscitis should be considered in hemodialysis patients who present with prolonged back pain with or without fever. Non-contrast MRI is an appropriate diagnostic tool for this condition. Vascular access infection increases the risk for infective spondylodiscitis in hemodialysis patients.

Outcome of conservative and surgical treatment of pyogenic spondylodiscitis: a systematic literature review. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2015; 25:983-99. [PMID: 26585975 DOI: 10.1007/s00586-015-4318-y] [Citation(s) in RCA: 126] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2015] [Revised: 10/30/2015] [Accepted: 11/01/2015] [Indexed: 12/17/2022]
Abstract
BACKGROUND Spondylodiscitis is a spinal infection affecting primarily the intervertebral disk and the adjacent vertebral bodies. Currently many aspects of the treatment of pyogenic spondylodiscitis are still a matter of debate. PURPOSE The aim of this study was to review the currently available literature systematically to determine the outcome of patients with pyogenic spondylodiscitis for conservative and surgical treatment strategies. METHODS A systematic electronic search of MEDLINE, EMBASE, Cochrane Collaboration, and Web of Science regarding the treatment of pyogenic spondylodiscitis was performed. Included articles were assessed on risk of bias according the Cochrane Handbook for Systematic Reviews of Interventions, and the quality of evidence and strength of recommendation was evaluated according the GRADE approach. RESULTS 25 studies were included. Five studies had a high or moderate quality of evidence. One RCT suggest that 6 weeks of antibiotic treatment of pyogenic spondylodiscitis results in a similar outcome when compared to longer treatment duration. However, microorganism-specific studies suggest that at least 8 weeks of treatment is required for S. aureus and 8 weeks of Daptomycin for MRSA. The articles that described the outcome of surgical treatment strategies show that a large variety of surgical techniques can successfully treat spondylodiscitis. No additional long-term beneficial effect of surgical treatment could be shown in the studies comparing surgical versus antibiotic only treatment. CONCLUSION There is a strong level of recommendation for 6 weeks of antibiotic treatment in pyogenic spondylodiscitis although this has only been shown by one recent RCT. If surgical treatment is indicated, it has been suggested by two prospective studies with strong level of recommendation that an isolated anterior approach could result in a better clinical outcome.

Purpose To analyze the suitability of magnetic resonance imaging (MRI) in distinguishing radiology images with a corresponding delineation of spondylitis and vertebral metastasis confirmed by histology results. Overview of Literature MRI is an accurate modality for assessing vertebrae and their disorders. Infections and metastasis are most commonly found in the vertebrae. It is difficult to differentiate between these two disorders both clinically and radiographically, particularly in atypical cases. Methods McNemar statistical test was used to analyze the data. Samples were chosen using the consecutive method. There were 35 samples (14 males and 21 females), consisting of 22 samples of spondylitis and 13 samples of metastasis confirmed on histology examination. Results Nineteen (86%) out of the 22 samples of histological spondylitis were diagnosed as having spondylitis on MRI, whereas all 13 samples of metastasis were 100% accurately diagnosed on MRI. Conclusions There was no statistically significant difference between diagnostic radiology using MRI and histological diagnosis with a p=0.250 (p>0.05). In this respect, MRI was more precise in diagnosing metastasis. Typical MRI description of spondylitis was the involvement of anterior vertebrae and components of intervertebral discs, stiffening of discs, paravertebral abscess, and involvement of the vertebral segment sequence. Typical MRI delineation of metastasis was involvement of the anterior posterior vertebral component, paravertebral mass, and skip lesions.

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2015; 25:1012-20. [PMID: 25895880 DOI: 10.1007/s00586-015-3936-8] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2014] [Revised: 04/06/2015] [Accepted: 04/06/2015] [Indexed: 12/19/2022]
Abstract
INTRODUCTION Established treatment options of spondylodiscitis, a rare but serious infection of the spine, are immobilization and systemic antibiosis. However, the available data for specific treatment recommendations are very heterogeneous. Our intention was to develop a classification of the severity of spondylodiscitis with appropriate treatment recommendations. MATERIALS AND METHODS From 10/1/1998 until 12/31/2004, 37 cases of spondylodiscitis were examined regarding medical history, gender status, location and extent of spondylodiscitis, type and number of operations. Subsequently, a classification of six grades according to severity has been developed with specific treatment recommendations. The further evaluation of our classification and corresponding treatment modalities from 1/1/2005 to 12/31/2009 including further 132 cases, resulted in a classification of only three grades of severity (the SSC--spondylodiscitis severity code), with a follow-up until 12/31/2011. Between 01/01/2012 and 12/31/2013, a prospective study of 42 cases was carried out. Overall, 296 cases were included in the study. 26 conservatively treated cases were excluded. RESULTS AND CONCLUSION The main localization of spondylodiscitis was the lumbar spine (55%) followed by the thoracic spine (34%). The classification of patients into 3 grades of severity depends on clinical and laboratory parameters, the morphological vertebral destruction seen in radiological examinations and the current neurological status. Therapies are adapted according to severity and they include a specific surgical management, systemic antibiotic therapy according to culture and sensitivity tests, physiotherapy and initiation of post-hospital follow-up. 40.6% of patients are associated with neurological deficits, classified as severity grade 3 and treated surgically with spinal stabilization and decompression. 46.9% of patients corresponded to severity grade 2, with concomitant vertebral destruction were dorsoventrally stabilized. The 31 patients of severity Grade 1 were treated surgically with dorsal stabilization. From 1998 to 2013, the time from the onset of symptoms to the first surgical treatment was about 69.4 days and has not changed significantly. However, the time from admission to surgical treatment had been reduced to less than 2 days. Also the time of hospitalization was reduced and we see positive effects regarding the sensation of pain. 270 patients underwent surgery. We treated 89% dorsally and 21% dorsoventrally. With the spondylodiscitis severity code, a classification of the severity of spondylodiscitis could be established and used for a severity-based treatment. In addition, specific parameters for the treatment of individual grades of severity can be determined in a clinical pathway.

Abstract
BACKGROUND Orthoses are external aids that are often used to treat pain and diseases affecting the spine, such as lumbago, whiplash, and disc herniation. In this review, we assess the effectiveness and complications of orthotic treatment for typical spinal conditions and after spinal surgery. The orthotic treatment of fractures and postural abnormalities are beyond the scope of this article. METHOD This review is based on a selective search in the Medline database with consideration of controlled trials, systematic reviews, and the recommendations of the relevant medical societies. RESULTS Three relevant systematic reviews and four controlled trials were found. Very few controlled trials to date have studied the efficacy of orthotic treatment compared to other conservative treatments and surgery. No definitive evidence was found to support the use of orthoses after surgery, in lumbar radiculopathy, or after whiplash injuries of the cervical spine. In a single trial, short-term immobilization was an effective treatment of cervical radiculopathy. Orthoses are not recommended for nonspecific low back pain. The potential complications of cervical orthoses include pressure-related skin injuries and dysphagia. CONCLUSION No definitive evidence as yet supports the use of orthoses after spinal interventions or in painful conditions of the cervical or lumbar spine. They should, therefore, be used only after individual consideration of the indications in each case.

Abstract
Study Design Retrospective review of patients who had pyogenic discitis and were managed surgically. Purpose To analyze the bacteriology, pathology, management and outcome of pyogenic discitis of the lumbar region treated surgically. Overview of Literature Surgical management of pyogenic discitis is still an infrequently used modality of treatment. Methods A total of 42 patients comprised of 33 males and 9 females who had pyogenic discitis with a mean age of 51.61 years (range, 16-75 years) were included in this study. All the cases were confirmed as having pyogenic discitis by pus culture report and histopathological examination. The mean follow-up period was 41.9 months. Results Debridement and posterior lumbar interbody fusion with autologous iliac bone graft was done in all cases. Thirteen (30.95%) patients had other medical co-morbidities. Five cases had a previous operation of the spine, and three cases had a history of vertebral fracture. Three patients were operated for gynaecological problems, and four cases had a history of urological surgery. L4-5 level was the most frequent site of pyogenic discitis. The most common bacterium isolated was Staphylococcus aureus (S. aureus). Radiologically good fusion was seen in the majority of patients. Conclusions Pyogenic discitis should be suspected in people having pain and local tenderness in the spinal region with a rise in inflammatory parameters in blood. The most common bacterium was S. aureus, but there were still a greater number of patients infected with other types of bacteria. Therefore, antibiotics therapy should be started only after isolating the bacteria and making the culture sensitivity report.

Abstract
UNLABELLED SURGICAL GOAL: Resolve infection and achieve primary stability of instrumentation and permanent fusion of the affected spinal segment by means of debridement of the focus of infection. Defect-filling using autologous/allograft bone or a spacer, as well as immobilization by means of dorsal instrumentation. INDICATION Acute and chronic thoracolumbar spondylodiscitis. CONTRAINDICATIONS Purely epidural abscesses requiring only decompression (fenestration). Defects whose size make a ventral approach necessary. SURGICAL TECHNIQUE Classic dorsal approach to the thoracolumbar spine. Pedicle placed using screws depending on the size of the spinal defect for mono-, bi-, or multisegmental spinal fusion. Exposure performed at the level of the infected spinal disc or vertebral body on the more strongly affected side. Focus of infection removed. Depending on the degree of infection, defect filling is carried out using autologous bone or cancellous allograft, followed by rod assembly. POSTOPERATIVE MANAGEMENT Back brace-free follow-up treatment, physiotherapy and back training. Antibiotic administration until inflammation values fall within the normal range, or for at least 14 days. RESULTS Successful fusion of affected segments, including resolution of infection, is reported in over 90% of cases described in the literature. The revision rate among our mostly multimorbid patient group with an average age of 66 years was 16%. Of 39 of the 114 (34%) patients with preoperative neurological deficits, 26 (66%) demonstrated postoperative regression. Nine patients (23%) showed no improvement, whilst exacerbation of existing neurological deficits was seen in four patients (11%). Staphylococcus was the major pathogen in 34% of cases.

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
An evidence-based recommendation for a standardized antibiotic therapy of spondylodiscitis has not yet been published. Crucial for conservative therapy is the verification of the causative organism and an appropriate antibiotic therapy. Intravenous antibiotic therapy should be administered for 2-3 weeks and a switched to oral administration for 6-12 weeks is then possible. If an empirical antimicrobial therapy is required a combination of ciprofloxacin and clindamycin, alternatively a combination of cefotaxim and flucloxacillin is recommended. Surgical removal of the infection by extensive debridement with stabilization and filling the resulting bone defect is desirable. Under the perception of a high local dose of antibiotic the defect filling with a mixture of cancellous bone and antibiotic-loaded hydroxyapatite and calcium sulfate is advisable.

Abstract
The incidence of pyogenic spondylodiscitis is low but has been steadily increasing in recent years. To date there has been no consensus concerning selection of the appropriate treatment, management and strategies and the recommendations for an operative strategy are still a highly controversial issue. In the literature a few statements have been published concerning therapeutic decision-making in pyogenic spondylodiscitis. The classification given in this article is based on clinical experience and retrospective data analysis considering the degree of segmental bony destruction, grade of kyphosis and instability, epidural involvement of the disease and neurological deficits, which are pivotal for therapeutic decision-making. The therapeutic procedure can be defined based on this classification.

Abstract
Specific and non-specific infections of the spine are rare. Due to their potential for severe instabilities, deformities and the impairment of neurological structures, the treatment is often prolonged and needs an interdisciplinary management. The clinical presentation is uncharacteristic, therefore diagnosis is often delayed. There are no prospective randomized studies for therapy recommendation. The surgical concept includes eradication of the infection and the reliable stabilization of involved segments. This concept is successful in most cases of endogenous vertebral osteomyelitis. The therapy of the exogenous spine infections after macro and micro surgery is more difficult, due to the critical wound situation and the involvement of the posterior parts of the spine. In these cases, infection-associated instability of the anterior part is complicated by critical posterior wound conditions. We present three cases of severe exogenous vertebral infections, where temporary external transpedicular spine fixation was used for salvage procedure, till soft tissue conditions have permitted a definitive internal stabilization.

Abstract
A young mother presented her 19-month-old boy to the general practitioner (GP) with a 24 h history of reluctance to stand or walk and a slightly raised temperature. The GP arranged an assessment by the paediatrician, who organised an ultrasound of the hips which was normal. Approximately 1 week later the patient became constipated as well, was seen again by another GP but no cause was found. Another week later mother consulted the initial GP again as the boy had not shown any signs of improvement and had become more irritable. The GP arranged a review by the paediatrician and MRI scans of the hips and back were performed. These scans showed normal hips but lumbar spine changes suggestive of a spondylodiscitic event. The patient was treated with intravenous antibiotics, a corset and analgesia and made an excellent recovery.

Abstract
Tuberculosis of the spine usually occurs with a latency period after primary infection with tuberculosis (TB) and the most frequent agent is Mycobacterium tuberculosis. The rate of TB has increased due to the impact of acquired immunodeficiency syndrome (AIDS) and more than 50% of skeletal tuberculosis is localized in the spine. Spinal tuberculosis was discovered by Pott in 1776. Magnetic resonance imaging (MRI) with gadolineum is the most sensitive imaging method. Diagnostic accuracy is given by direct detection of Mycobacterium tuberculosis by punction or biopsy. Granuloma of the spine can lead to abscesses, severe spinal deformity with instability and potentially paraplegia. Chemotherapy is effective with a minimum duration of 6-12 months. In cases with neurological deficits and severe deformity there is an additional indication for surgical therapy. In the acute phase a posterior instrumentation, anterior debridement and reconstruction of the defect is indicated. After recovery of the spinal tuberculosis Pott's kyphosis could remain and operative correction can be managed by pedicle substraction osteotomy.

Abstract
Spondylodiscitis is an inflammatory disease, usually infectious, of one or more vertebral bodies and of corresponding intervertebral discs. The fungal aetiology is rare (less than 5% of cases), affecting mostly immunocompromised individuals. It is often a delayed diagnosis by the indolence of symptoms, presenting itself as a serious infection, which may result in important functional consequences. The authors present the case of a 75-year-old male, with constitutional complaints and intense back pain. Prior recent history of left hemicolectomy due to diverticulitis with multiple surgical complications, resulted in prolonged intensive care unit hospitalisation, and, later on, an episode of fungal endophthalmitis. The diagnosis of spondylodiscitis L5/S1 was performed by MRI. The patient underwent surgical disco-vertebral debridement and isolation of a Candida albicans was seen in the collected surgical material. No evidence of an immunossupressive status was found. Treatment was complemented with liposomal amphotericin B in the maximum recommended dose.

Abstract
Spondylodiscitis affects children aged between two and eight years, and mainly involves the lumbar or lumbosacral spine. Diagnosis is difficult because the symptoms are not very specific and due to the children's difficulty in communicating. Unlike adults, children have vascularised intervertebral discs, which explains the higher incidence of this disease in this age group. C-reactive protein, and blood and urine cultures are important laboratory tests. In most cases, fine needle or traditional biopsy helps identify the pathogen particularly in patients who do not respond to the antibiotic therapy test. Magnetic resonance imaging has high sensitivity and specificity in the investigation of pyogenic infection of the spine, particularly in the early stages, when these changes are not shown in other imaging tests. X-rays can take up to six weeks to show changes. The first radiographic sign of infection is the irregularity of the vertebral endplates in the infection area, followed by their erosion and that of the adjacent bone, decreased disc space, segmental collapse, loss of lordosis (in cases of low back involvement) and ultimately, permanent structural deformity. After eight to twelve weeks, local regeneration occurs, accompanied by bone sclerosis arising from the formation of new trabecular bone, replacing the necrotic cancellous bone. Effective treatment often leads to bone fusion of the affected disc space. However, when no therapy is adopted, total vertebral collapse can occur. The treatment involves immobilisation, antibiotic therapy, and surgical decompression in more advanced cases.

Abstract
Despite modern diagnostic imaging options pyogenic infections of the spine are often detected tardily and therefore accompanied by a high mortality rate. To ensure an efficient and adequate therapy it is necessary to identify and treat the focus of inflammation. The recommendations for the operative strategy are still a highly controversial issue. On the other hand no classification and guidelines for surgical treatment and treatment strategies of pyogenic spinal infection have yet been published.Pyogenic spinal infections are often underestimated in frequency of occurrence and severity of symptoms. From 1994 until 2008, 269 patients suffering from an infection of the thoracic and lumbar spine were treated in the Department of Orthopedic Surgery Heidelberg and 221 patients underwent surgery. Within the scope of a clinical trial clinical aspects and therapeutic consequences of patients with pyogenic spinal infections were retrospectively investigated. Based on the study data a classification of pyogenic spinal infections of the thoracic and lumbar spine and a guide for surgical decision-making was developed.

Abstract
OBJECTIVE The objective of this study was to evaluate and compare the diagnostic value of the open biopsy technique and the percutaneous biopsy techniques in lumbar spondylodiscitis. METHODS Between January 2004 and December 2009, we retrospectively reviewed the medical records of 57 patients with infectious lumbar spondylodiscitis. The etiologic diagnosis of the infectious spondylodiscitis was obtained by two methods. Of 57 cases, twenty-seven patients underwent open biopsy and thirty patients underwent percutaneous needle biopsy including computed tomography (CT) - guided and fluoroscopy-guided needle aspiration. All biopsies were performed by experienced two neurosurgeons and one interventional radiologist. RESULTS Of the 57 cases radiologically consistent with spinal infection, 29 (50.9%) biopsy specimens resulted in positive cultures and 28 (49.1%) returned negative cultures. According to the type of biopsy techniques, the culture-positive rate was higher (p=0.005) in the open biopsy group than the percutaneous needle biopsy group. 19 (70.4%) of 27 biopsy specimens were positive in the open biopsy group, and 10 (33.3%) of 30 biopsy specimens were positive in the percutaneous needle biopsy group. Furthermore, the open biopsy showed higher positive culture rate than the percutaneous needle biopsy in cases with administration of empirical antibiotics although there was no statistically significant (p=0.137). CONCLUSIONS Open biopsy should be considered for administration of organism-specific antibiotics for the successful treatment when percutaneous needle yield negative result. Furthermore, empirical antibiotics should be delayed until results of cultures unless the patient is severely septic, critically ill, neutropenic or neurologically compromised.

Abstract
PURPOSE Pyogenic infections of the spine are relatively rare with an incidence between 1:100,000 and 1:250,000 per year, but the incidence is increasing due to increases in average life-expectancy, risk factors, and medical comorbidities. The mean time in hospital varies from 30 to 57 days and the hospital mortality is reported to be 2-17%. This article presents the relevant literature and our experience of conservative and surgical treatment of pyogenic spondylodiscitis. METHOD We have performed a review of the relevant literature and report the results of our own research in the diagnosis and treatment of pyogenic spondylodiscitis. We present a sequential algorithm for identification of the pathogen with blood cultures, CT-guided biopsies and intraoperative tissue samples. Basic treatment principles and indications for surgery and our surgical strategies are discussed. RESULTS Recent efforts have been directed toward early mobilisation of patients using primary stable surgical techniques that lead to a further reduction of the mortality. Currently our hospital mortality in patients with spondylodiscitis is around 2%. With modern surgical and antibiotic treatment, a relapse of spondylodiscitis is unlikely to occur. In literature the relapse rate of 0-7% has been recorded. Overall the quality of life seems to be more favourable in patients following surgical treatment of spondylodiscitis. CONCLUSION With close clinical and radiological monitoring of patients with spondylodiscitis, conservative and surgical therapies have become more successful. When indicated, surgical stabilisation of the infected segments is mandatory for control of the disease and immediate mobilisation of the patients.

Abstract
INTRODUCTION Low back pain (LBP) is an epidemiologically and economically relevant health care problem appropriate for quality assurance approaches. Therefore an expert panel (AQUIK) of the National Association of Statutory Health Insurance Physicians has proposed three quality indicators (QI) for monitoring the quality of ambulatory care for LBP. The aim of this article is to present and evaluate the proposed QIs. MATERIAL AND METHODS The three proposed QIs relating to red flags, imaging and sick leave certificates were evaluated with regard to the underpinning evidence, epidemiology and feasibility. Guidelines and original research as well results from surveys and observational studies evaluating adherence to LBP guidelines were used for assessment. RESULTS The expert panel concluded that only the recording of red flags is a relevant and feasible QI. Despite a two-stage expert method the epidemiology of LBP, feasibility and existing routine health care data were not sufficiently taken into account. The author's conclusion differs in two instances. The red flag concept is not sufficiently clinically validated and recordable to be used as a QI. Otherwise imaging is considered a suitable QI given the observed overuse and the availability of billing data. CONCLUSION Deriving valid and pragmatic QI from LBP guidelines for evaluating care for LBP is difficult. The core messages of guidelines are only recommendations with limited precision and transferability to individual patients. For pragmatic reasons definition of an upper or lower proportion of patients receiving a given health care service is recommended instead of tedious individual evaluation. Reasonable estimates can be based on data from research on health care services. Because of this uncertainty QIs should be evaluated before they are used as a steering instrument.

Abstract
OBJECTIVE Bacterial spondylodiscitis is a rare entity in spinal surgery. This study analyses the postoperative results of 53 patients, focusing on the history, the treatment, and the course of the disease. MATERIAL AND METHODS This retrospective study is based on the patients' medical charts, including the laboratory and microbiological data. RESULTS Twenty-nine patients suffered from different neurological deficits ranging from isolated mild hypaesthesia (n=1) to complete paraplegia (n=6). Depending on the affected area and the extension of the infection, surgery was done either as simple decompression in 16 cases or as decompression combined with a ventral or dorsoventral stabilization in 37 patients. Staphylococcus aureus was the most important triggering organism (n=23). After a median follow-up of 11.25 months, three patients had died, and 22 patients were still disabled because of persisting pain or neurological disturbances. CONCLUSION Because of persistent neurological deficits and possible lethal complications, spondylodiscitis remains a severe problem. Management comprises targeted antibiotic therapy and surgery in selected cases.

Abstract
The localization of HIV-1 proviruses in compositional DNA fractions from 27 AIDS patients during the chronic phase of the disease with depletion of CD4+ and different levels of viremia showed the following. (1) At low viremia, proviruses are predominantly localized in the GC-richest isochores, which are characterized by an open chromatin structure; this result mimics findings on HIV-1 integration in early infected cells in culture. (2) At higher viremia, an increased distribution of proviruses in GC-poor isochores (which match the GC poorness of HIV-1) was found; this suggests a selection of cells in which the 'isopycnic' localization leads to a higher expression of proviruses and, in turn, to higher viremia. (3) At the highest viremia, integrations in GC-rich isochores are often predominant again, but generally not at the same level as in (1); this may be the consequence of new integrations from the extremely abundant RNA copies.
