The effect of lumbar corticosteroid injections on postoperative infection in lumbar arthrodesis surgery.

We sought to characterize the association between lumbar corticosteroid injections and postoperative infection rate for patients in the Military Health System undergoing lumbar arthrodesis. The Military Health System Data Repository was searched for all patients undergoing lumbar arthrodesis from 2009 to 2014. Current Procedural Terminology (CPT) codes were used to identify the subset of patients who also received preoperative lumbar corticosteroid injections. These patients were stratified by timing, type, and number of injections. Infection rates were compared to the control group of patients who did not receive preoperative lumbar corticosteroid injections. The search identified 3403 patients who had undergone lumbar arthrodesis from 2009 to 2014 within the Military Health System. 612 patients had received lumbar corticosteroid injections prior to surgery (348 epidural, 264 facet). The control group consisted of the remaining 2791 patients. Overall post-operative infection rate was 1.47% with an infection rate in the injection group of 1.14% versus 1.54% in the control group. When stratified by time, infection rates ranged from 0% to 1.85% in the injection groups. No differences between injection and control groups reached statistical significance in any subgroup analysis. Post-operative infection rate is not significantly increased in patients receiving lumbar corticosteroid injections (LCSIs) prior to lumbar arthrodesis. No differences were observed in infection rates based on timing, type, or number of injections prior to surgery.

Therapeutic effect of minimally invasive catheter drainage and local chemotherapy for the lumbosacral tuberculosis without neural symptoms.

Increasing number of studies have shown growing incidence of lumbosacral tuberculosis and its complications. However, the treatment options for this disorder are still limited.To evaluate the long-term therapeutic effect and prognosis of minimally invasive puncture catheter drainage and Isoniazid local chemotherapy for the treatment of lumbosacral tuberculosis without neural symptoms under the guidance of computed tomography (CT).A total of 45 patients with asymptomatic lumbosacral tuberculosis were treated by minimally invasive catheter drainage under CT guidance. Forty-two cases had been followed up, which included 22 women and 20 men with an average age of 36.45 years old. Isoniazid was injected locally and antituberculotic drugs were administered for postoperative treatment. Oswestry Disability Index (ODI), visual analogue scale (VAS) evaluation and Cobb angle were recorded before and after operation.Forty-two patients had been followed up and the follow-up term was from 1.2 to 8.5 years (average 60 months). All patients were healed without recurrent cases. The ODI were improved from 14.86 ±â€Š2.02 before operation to 1.48 ±â€Š1.55 after operation. The post-operative (4.19 ±â€Š1.17) VAS score was improved compared to the pre-operative VAS score (0.55 ±â€Š0.55). The post-operative Cobb angle (6.19°â€Š±â€Š3.85°) was also improved relatively to the preoperative Cobb angle (5.90°â€Š±â€Š3.71°).Minimally invasive puncture catheter drainage combined with Isoniazid local chemotherapy is an effective method for lumbosacral tuberculosis without neural symptom. Meanwhile, it can be applied for the treatment of spinal tuberculosis before open surgery.

Single posterior surgical management for lumbosacral tuberculosis: titanium mesh versus iliac bone graft: A retrospective case-control study.

Recently, the one-stage posterior approach for treating spinal tuberculosis (TB) has gained popularity. However, large bony defects after debridement remain a major challenge in posterior surgery. The present retrospective study aims to compare the clinical outcomes of posterior-only surgical management by titanium mesh versus iliac bone grafts for treating lumbosacral TB. This was a retrospective cohort study. From January 2006 to April 2012, 36 patients with lumbosacral TB were treated at our department. The 36 cases were divided into 2 groups: 17 patients in Group A (titanium mesh) underwent one-stage posterior internal fixation, debridement, and titanium mesh bone fusion. The 19 patients in Group B (iliac bone graft) underwent posterior instrumentation, debridement, and iliac bone graft in a single procedure. The clinical and radiographic results for the 2 groups were analyzed and compared. The mean year of patients was 49.9 ±â€Š15.4 months in group A and 55.5 ±â€Š12.6 months in group B. All patients were followed up for an average of 47.3 ±â€Š8.1 months (range 36-60 months). Spinal TB was completely cured and no intraspinal infection and central nervous system complications of TB infection occurred. Bone fusion was achieved 6.4 ±â€Š1.9 months in group A and 7.8 ±â€Š2.1 months in group B. There was no significant statistical difference in bone fusion between the 2 groups (P > .05). The Oswestry Disability Index score (ODI) significantly improved between the preoperative and the last visit in either group. However, no significant difference was observed between the 2 groups at last visit (P > .05). There were significant differences between groups regarding the postoperative lumbosacral angle and angle correction loss at the final follow-up (P < .05). The average operative complication rate of Group A was less than that of Group B. Both iliac bone and titanium mesh can effectively construct anterior column defects in posterior surgery. The titanium mesh has the advantage of minor surgical invasion, effective reconstruction of large defects, and ideal sagittal alignment in lumbosacral TB for patients with osteoporosis and poor iliac bone quality.

Toxocara canis myelitis involving the lumbosacral region: a case report.

CONTEXT: Toxocara canis is a parasite known to cause visceral larva migrans. The infection rarely affects the central nervous system but there have been several reports of myelitis caused by visceral larva migrans due to Toxocara canis. In previous reported cases, the lesions were located in the thoracic or cervical spinal cord. To the best of our knowledge, this is the first report of a lesion involving the lumbosacral region. FINDINGS: A 60-year-old man developed weakness and dysesthesia in the lower limbs. The symptoms resolved spontaneously, but recurred after five months. One month later, the patient developed pollakiuria and constipation. He was a dog owner and frequently ate raw chicken meat and beef liver. Sagittal T2-weighted image (T2WI) showed swelling and hyperintensity in the spinal cord from T10 to the lumbosacral region and focal nodular enhancement on the posterior segment of the lumbar spinal cord. Blood cell counts showed slight eosinophilia and elevated serum immunoglobulin E level. Cerebrospinal fluid examination showed slight pleocytosis with eosinophilia. Enzyme-linked immunosorbent assay showed high levels of anti-Toxocara antibodies in the serum and cerebrospinal fluid. In addition, confirmatory test by Western blot was positive. The patient was initially treated with intravenous methylprednisolone with slight improvement in muscle weakness. Albendazole was added with a second course of intravenous methylprednisolone. The muscle weakness in the lower limbs improved considerably, and swelling and hyperintensity on T2WI almost disappeared. CONCLUSION: Our results suggest that Toxocara canis myelitis cannot be discounted even if the myelitis involves the lumbosacral region.

Incidence of microbiological contamination of local bone autograft used in posterior lumbar interbody fusion and its association with postoperative spinal infection.

OBJECTIVE: The aim of this study was to examine the results of microbiological cultures from local bone autografts used in posterior lumbar interbody fusion (PLIF) and to identify their association with postoperative spinal infection. METHODS: The authors retrospectively evaluated cases involving 328 patients who had no previous spinal surgeries and underwent PLIF for degenerative diseases with a minimum 1-year follow-up. Local bone was obtained during laminectomy, and microbiological culture was performed immediately prior to bone grafting. The associations between culture results from local bone autografts and postoperative spinal infections were evaluated. RESULTS: The contamination rate of local bone was 4.3% (14 of 328 cases). Coagulase-negative Staphylococcus (29%) was the most common contaminant isolated, followed by Streptococcus species and methicillin-sensitive Staphylococcus aureus. Of 14 patients with positive culture results, 5 (35.7%) had postoperative spinal infections and were treated with intravenous antibiotics for a minimum of 4 weeks. One of these 5 patients also underwent reoperation for debridement during this 4-week period. Regardless of the microbiological culture results, the infection rate after PLIF with local bone autograft was 2.4% (8 of 328 cases), with 5 (62.5%) of 8 patients showing positive results on autograft culture. CONCLUSIONS: The incidence of contamination of local bone autograft during PLIF was considerable, and positive culture results were significantly associated with postoperative spinal infection. Special attention focused on the preparation of local bone for autograft and its microbiological culture will be helpful for the control of postoperative spinal infection.

Candida albicans lumbar spondylodiscitis in an intravenous drug user: a case report.

BACKGROUND: Spondylodiscitis leads to debility, and few data exist on Candida spondylodiscitis in patients with intravenous drug use. CASE PRESENTATION: We present a case of Candida albicans lumbar spondylodiscitis in a patient with intravenous drug use. This patient was treated with surgical debridement and 9 months of fluconazole therapy, and the neurological deficits resolved completely. The infection did not recur clinically or radiologically during 9 months of follow-up. CONCLUSION: Although Candida albicans lumbar spondylodiscitis is rare, Candida should be suspected as a causative pathogen in patients with intravenous drug use except for Staphylococcus aureus, Pseudomonas aeruginosa, and Mycobacterium tuberculosis. As soon as Candida albicans lumbar spondylodiscitis is suspected, magnetic resonance imaging and percutaneous biopsy should be performed. Surgical intervention combined with treatment with antifungal medications can successfully eradicate the infection and resolve the neurological deficits.

Bacteroides fragilis vertebral osteomyelitis complicated by percutaneous epidural adhesiolysis.

STUDY DESIGN: A case report of anaerobic vertebral osteomyelitis after percutaneous epidural adhesiolysis. OBJECTIVE: To present a case of Bacteroides fragilis spondylodiscitis (BFS) secondary to percutaneous epidural adhesiolysis in a 38-year-old woman without predisposing factors. SUMMARY OF BACKGROUND DATA: Most cases of BFS result from hematogenous spread from a perianal abscess or sigmoidoscopy or local spread from an adjacent infection. However, BFS due to direct inoculation after percutaneous epidural adhesiolysis has not been previously reported. METHODS: A 38-year-old woman presented with spondylodiscitis at the L4-L5 level 2 weeks after percutaneous epidural adhesiolysis. Despite empirical antibiotherapy, the spondylodiscitis and an epidural abscess became much aggravated. Open biopsy and curettage was performed, and metronidazole sensitive Bacteroides fragilis was identified by tissue culture. RESULTS: Metronidazole was administrated for 5 weeks and symptoms were completely resolved. Follow-up magnetic resonance imaging showed that the spondylodiscitis was completely cured. CONCLUSION: This is the first report to be issued regarding BFS secondary to percutaneous epidural adhesiolysis. In our case, the pathogenesis may have been direct inoculation of Bacteroides fragilis into the epidural space and disc during percutaneous epidural adhesiolysis because the procedural approach used was adjacent to the anus.

Lumbo-sacral spine disease due to bovine tuberculosis in a patient with concurrent pulmonary disease.

Lumbo-sacral spinal disease due to bovine tuberculosis (TB) in a patient with concurrent pulmonary disease is rare. We report this unpredicted finding in an immunocompetent patient and discuss the natural history in an area of low prevalence.

Lumbar osteomyelitis with Pseudomonas.

Osteomyelitis is the inflammation of bone secondary to infection with pyogenic organisms. Pseudomonas aeruginosa is usually associated with nosocomial infections and due to its ability to acquire resistance to almost all antibiotics, infections with Pseudomonas pose a great challenge to the physicians. A number of new synergistic combinations have been used in order to treat these organisms and one of the methods is to combine chemicals with systemic antibiotics. In this case we represent a successful eradication of multidrug resistant Pseudomonas using a combination of acetic acid and systemic antibiotics.

Piomiositis multifocal en un paciente previamente sano / Multifocal pyomiositis in a previously healthy patient

Presentamos un caso de piomiositis en una niña de 3 años sin patología subyacente. La piomiositis es una enfermedad común en los países tropicales y rara en los de clima templado. Aunque en España se está comunicando con una frecuencia cada vez mayor. El patógeno más común es el Staphylococcus aureus. La enfermedad puede manifestarse de modo sutil e inespecífico dificultando el diagnóstico. El retraso de éste puede implicar complicaciones graves o incluso la muerte. Para su detección son esenciales las técnicas de imagen, ecografía, tomografía computarizada, resonancia magnética y gammagrafía isotópica. El tratamiento se basa en la antibioticoterapia y el drenaje, no estando bien establecido cuál debe ser su duración. Nuestra paciente se recuperó sin complicaciones tras la incisión y el drenaje del absceso fundamental y la administración de antibióticos antiestafilocócicos

We present a case of pyomyositis in an otherwise healthy 3 - year-old girl. Pyomyositis is a common disease in the tropics that is reported with increasing frequency in Spain. The most common pathogen is Staphylococcus aureus. This disease may give rise to subtle, non-specific or misleading signs and symptoms. Delayed diagnosis and treatment may lead to serious complications or even death. The imaging tools included ultrasonography, computed tomography, magnetic resonance imaging and gallium- 67 scan. Early ultrasound examination of any suspected lesions can help to establish the diagnosis. Treatment, the duration of which has not been definitively established, consists mainly of antibiotic therapy and surgical drainage. Our patient recovereds moothly, without complications, after incision, drainage and administration of antistaphylococcal antibiotics

Development of Daptomycin resistance in vivo in methicillin-resistant Staphylococcus aureus.

Daptomycin is a new lipopeptide antibiotic that is rapidly bactericidal against Staphylococcus aureus. We report daptomycin resistance and treatment failure in 2 patients with osteomyelitis due to methicillin-resistant S. aureus. Disk diffusion susceptibility testing failed to detect resistance. Daptomycin at high concentration retained bactericidal activity against resistant isolates.

Case report: greater meningeal inflammation in lumbar than in ventricular region in human bacterial meningitis.

Differences in the composition of ventricular and lumbar cerebrospinal fluid (CSF) based on single pairs of samples have previously been described. We describe a patient that developed post-surgical recurrent meningitis monitored by daily biochemical and bacteriological CSF analysis, simultaneously withdrawn from lumbar space and ventricles. A 20-year-old Caucasian man was admitted to the ICU after a resection of a chordoma that extended from the sphenoidal sinus to the anterior face of C2. CSF was continuously leaking into the pharyngeal cavity after surgery, and three episodes of recurrent meningitis, all due to Pseudomonas aeruginosa O12, occurred. Our case showed permanent ventricular-to-lumbar CSF gradients of leukocytes, protein and glucose that were increased during the acute phase of meningitis, with the greatest amplitude being observed when bacteria were present in both ventricular and lumbar CSF. This might suggest a greater extent of meningeal inflammation in the lumbar than in the ventricular region. Our case also showed that the increase in intravenous antibiotics (cefepim from 8 to 12 g/day and ciprofloxacine from 1.2 to 2.4 g/day) led to an increase in concentration in plasma but not in CSF.

Brucellar spondylitis.

We carried out a prospective analysis of 86 patients with brucellosis, and 26 (30%) cases were diagnosed as brucellar spondylitis. Two patients had cervical involvement, two thoracic, and 21 lumbosacral as seen in MRI. Four patients had epidural abscess and two had paravertebral abscess. All patients received combined antibiotic therapy for 4 to 12 months. Those with cervical involvement underwent surgical treatment because of medullar compression. Neither death nor severe sequelae were observed.

Paraplegia associated with brucellosis involving the anterior lumbrosacral nerve roots.

We report the case of a 21-year-old man with paraplegia due to brucellosis involvement of lumbosacral anterior roots. Lumbosacral magnetic resonance imaging showed contrast enhancement of anterior roots and the anterior part of duramater. Conduction block was found at the level of the lumbosacral anterior roots by electrophysiological studies, including magnetic stimulation study. Wright agglutination, Rose Bengal tests and bacterial culture obtained from cerebrospinal fluid confirmed the diagnosis of neurobrucellosis. Oral administration of ceftriaxon with additional rifampin was effective, and after 3 months of treatment, laboratory data resolved and clinical signs partially improved.

[Intervertebral discitis caused by staphylococcal sepsis]. / Zapalenie tarczy miedzykregowej spowodowane sepsa gronkowcowa.

The aim of the study was to present the intervertebral discitis of L5-S1 region and adjoining vertebrae in the course of staphylococcal sepsis. A 51-year-old man was treated in hospital because of sudden very strong pain in a lumbar-sacral region of spine with irradiation towards both legs. The patient had general symptoms of infection. The diagnosis of intervertebral discitis of L5-S1 region was made on the basis of magnetic resonance imaging and computed tomography. In case of radicular symptoms accompanied by very strong back pain, intervertebral discitis should be considered during diagnostic investigation.

Paraspinal abscess following facet joint injection.

Injection to the zygapophysial joint is a procedure which is performed frequently for diagnostic or therapeutic reasons in the management of back pain. It is generally considered to be free of significant complications. We report a patient who developed a paraspinal abscess following a lumbar facet joint injection.
