We report a case of Aspergillus terreus discitis which developed in a patient with acute lymphoblastic leukemia following induction chemotherapy. A. terreus was isolated from sputum, one month earlier, but the physician did not consider it significant at the time. Magnetic resonance imaging study showed the involvement of L3-4, L4-5 and L5-S1 intervertebral discs. Etiology was established by means of histology and culturing a surgical specimen of disc materials. Our patient survived after a surgical debridement and amphotericin B administration with a total dose of 2.0 g. Discitis caused by Aspergillus terreus is a very rare event. A. terreus is one of the invasive Aspergillus species. The pathogenetic mechanism is discussed and the literature is reviewed.

Postoperative infections following spine surgery are usually attributable to bacterial organisms. Staphylococcus aureus is known to be the most common single pathogen leading to this infection, and the number of infections caused by methicillin-resistant Staphylococcus aureus is increasing. However, there is a paucity of literature addressing postoperative infection with Mycobacterium tuberculosis. We encountered a case of tuberculous spondylitis after spine surgery. A man had fever with low back pain three weeks after posterior interbody fusion with instrumentation for a herniated intervertebral disc at the L4-L5 level. He had been treated with antibiotics for an extended period of time under the impression that he had a bacterial infection, but his symptoms and laboratory data had not improved. Polymerase chain reaction for Mycobacterium tuberculosis turned out to be positive. The patient's symptoms finally improved when he was treated with antituberculosis medication.

OBJECTIVETo explore the surgical measurements and principles in the treatment of thoracic and thoracolumbar spinal tuberculosis.
METHODSFrom 2001 to 2008, 232 cases of thoracic or thoracolumbar spinal tuberculosis were treated by operations in the study, including 148 males and 84 females with an average age of 37.8 years ranging from 20 to 76 years. Preoperative assessment displayed as follow: Cobb angles of kyphosis < 30 degrees in 65 cases, 30 degrees to 60 degrees in 147 cases, > 60 degrees in 20 cases; Frankel B grade in 13 cases, C in 12 cases, D in 41 cases, E in 166 cases. Among them, 48 cases were performed with one-stage transpedicular screw system and anterolateral debridement by single incision, 184 cases with one-stage anterior approach (debridement, fusion, and plate-screw fixation) routinely. The tissues and liquor puris debrided from focus were sent for pathological examination, Bacillus tuberculosis detection and culture, and drug sensitivity test. The patients were given anti-tuberculosis therapy according the results of drug sensitivity test for 1 to 1.5 years. The followed-up included relapse rate, fusion of the bone graft, the status of neurological restoring, kyphosis correction etc.
RESULTSAll 232 cases recovered from perioperation and 230 cases got primary wound healing, only 2 cases performed with single incision one-stage posterior instrumentation and anterolateral debridement got complications of wound healing problems and the sinus formation,which delayed healed by changing dressings. The complications included intercostals neuralgia in 135 cases and pneumothorax or hydrothorax in 13 cases, which needed not special handling. All the patients in this series got the followed-up ranging from 1.0 to 4.5 years (means 2.6 years). No recurrence within followed-up period and bone union was found in all cases. All 66 cases with the neurological deficits recovered partially or totally. Kyphosis correction were achieved by 27.5 degrees on average postoperatively and showed a mild loss of 4.2 degrees on average during followed-up period. All cases were confirmed with Bacillus tuberculosis infection by pathology. Bacillus tuberculosis was detected and culture successfully in 107 cases (46.1%), 40 strains (37.4%) were drug resistant and in which 8 strains (7.5%) were multi-drug resistant.
CONCLUSIONFor the treatment of thoracic and thoracolumbar spinal tuberculosis, the best treatment include directional chemotherapy, one-stage anterior approach with thorough debridement, auto-rib or Ti-mesh fusion, and plate-screw fixation.

Aspergillosis is a rare cause of spondylitis. Moreover, early diagnosis by MR imaging and adequate treatment can prevent the serious complications of fungal infection. To our knowledge, the MR findings of multilevel aspergillus spondylitis in the cervico-thoraco-lumbar spine have not been previously described. Here, we report the MR findings of aspergillus spondylitis involving the cervical, thoracic, and lumbar spine in a liver transplant recipient.

BACKGROUND: Previous reports have observed differences only in infection rates between posterolateral fusion and posterior lumbar interbody fusion (PLIF). There have been no reports that describe the particular features of surgical site infection (SSI) in PLIF. In this study, we endeavor to identify the distinguishing characteristics and risk factors of SSI in PLIF. METHODS: Our study undertook a review of a case series of an institute. Patients who had undergone PLIF consecutively in the author's hospital were reviewed. Two proactive procedures were introduced during the study period. One was irrigation of the autolocal bone, and the other was the intradiscal space irrigation with a nozzle. Infection rate and risk factors were analyzed. For subgroup analysis, the elapsed time to a diagnosis (ETD), clinical manifestations, hematologic findings, and causative bacteria were examined in patients with SSI. RESULTS: In a total of 1,831 cases, there were 30 cases of SSI (1.6%). Long operation time was an independent risk factor (p = 0.008), and local bone irrigation was an independent protective factor (p = 0.001). Two cases of referred SSI were included in the subgroup analysis. There were 6/32 (19%) superficial incisional infections (SII), 6/32 (19%) deep incisional infections (DII), and 20/32 (62%) organ/space infections (O/SI). The difference of incidence among three groups was significant (p = 0.002).The most common bacteria encountered were methicillin-resistant Staphylococcus epidermidis followed by methicillin-resistant S. aureus in incisional infections, and no growth followed by S. epidermidis in O/SI. ETD was 8.5 +/- 2.3 days in SII, 8.7 +/- 2.3 days in DII and 164.5 +/- 131.1 days in O/SI (p = 0.013). CONCLUSIONS: The rate of SSI in PLIF was 1.6%, with the most common type being O/SI. The causative bacteria of O/SI was of lower virulence than in the incisional infection, and thus diagnosis was delayed due to its latent and insidious feature. Contamination of auto-local bone was presumed attributable to the progression of SSI. Irrigation of auto-local bone helped in the reduction of SSI.

OBJECTIVE:
To establish a proper animal model of pyogenic spondylitis, to evaluate the efficacy of silver nanoparticles for treatment of spinal pyogenic infections, and to explore the distribution of the particles in the body of the animals.
METHODS:
Staphylococcus aureus was inoculated into intervertebral discs of rabbits to establish a spinal pyogenic infection model. These rabbits were divided into Group A [0.1 mg/(kg.d)], Group B [1 mg/(kg.d)], and a Control group. Groups A and B were injected with different doses of silver nanoparticles solution daily at locally infected side. Two weeks later, bacterial cultures, radiographic outcomes, histopathology were analyzed. Atomic absorption spectrometry was utilized to measure silver contents in some vital organs of the rabbits to detect the distribution and accumulation of silver particles.
RESULTS:
Staphylococcus aureus (100 CFU/mL), induced 100% pyogenic spondylitis. 1 mg/kg dose of silver nanoparticles solution could effectively inhibit the occurrence of spinal pyogenic infection with the effective rate of 75%. While the effect of 0.1 mg/kg dose of silver nanoparticles solution was less obvious, the efficiency was only 25%. Significant numbers of silver nanoparticles were observed to accumulate in the animal. In the 1 mg/kg group silver was deposited mainly in the spinal cord, liver, kidneys, spleen, and testicles, while in the 0.1 mg/kg group it accumulated only in the spinal cord.
CONCLUSION
Local administration of silver nanoparticles can effectively prevent and treat pyogenic spondylitis; the particles accumulate in the body commensurate with the administered drug concentration.

According to the literature, thoracic outlet syndrome (TOS) secondary to the malunion of displaced fractures of the clavicle is rare. Various surgical methods, including simple neurolysis, resection of the first rib or clavicle and corrective osteotomy, have been reported. We report a case of TOS secondary to malunion of the clavicle that was treated by an anterior and middle scalenectomy without a rib resection.

BACKGROUND: Infective spondylodiscitis usually occurs in patients of older age, immunocompromisation, co-morbidity, and individuals suffering from an overall poor general condition unable to undergo reconstructive anterior and posterior surgeries. Therefore, an alternative, less aggressive surgical method is needed for these select cases of infective spondylodiscitis. This retrospective clinical case series reports our novel surgical technique for the treatment of infective spondylodiscitis. METHODS: Between January 2005 and July 2011, among 48 patients who were diagnosed with pyogenic lumbar spondylodiscitis or tuberculosis lumbar spondylodiscitis, 10 patients (7 males and 3 females; 68 years and 48 to 78 years, respectively) underwent transpedicular curettage and drainage. The mean postoperative follow-up period was 29 months (range, 7 to 61 months). The pedicle screws were inserted to the adjacent healthy vertebrae in the usual manner. After insertion of pedicle screws, the drainage pedicle holes were made through pedicles of infected vertebra(e) in order to prevent possible seeding of infective emboli to the healthy vertebra, as the same instruments and utensils are used for both pedicle screws and the drainage holes. A minimum of 15,000 mL of sterilized normal saline was used for continuous irrigation through the pedicular pathways until the drained fluid looked clear. RESULTS: All patients' symptoms and inflammatory markers significantly improved clinically between postoperative 2 weeks and postoperative 3 months, and they were satisfied with their clinical results. Radiologically, all patients reached the spontaneous fusion between infected vertebrae and 3 patients had the screw pulled-out but they were clinically tolerable. CONCLUSIONS: We suggest that our method of transpedicular curettage and drainage is a useful technique in regards to the treatment of infectious spondylodiscitic patients, who could not tolerate conventional combined anterior and posterior surgery due to multiple co-morbidities, multiple level infectious lesions and poor general condition.

Transarterial chemoembolization (TACE) is one of the most effective therapies for unresectable hepatocelluar carcinoma or metastatic hypervascular tumors. Abscess occurring in the other organs beside the liver after TACE is a complication that often occurs, sometimes potentially fatal. We report a case of spinal epidural abscess occurred after liver abscess complicated by TACE in a patient with metastatic neuroendocrine tumors to the liver. A 67-year-old female underwent TACE first for the metastatic lesions to liver, with a history of pancreatoduodenectomy for the primary pancreatic neuroendocrine tumor. Four days after TACE, sudden high fever occurred, and liver abscess was found on abdominal CT. Two days later, back pain and radiating pain to the right leg occurred, and lumbar spine MRI showed spinal epidural abscess. After intravenous antibiotics for 8 weeks and partial laminectomy, the patient recovered and was discharged without complications.

The effect and safety of anterior debridement and fusion with a minimally invasive approach combined with posterior fixation via the Wiltse approach were assessed in the single-level lumbar pyogenic spondylodiscitis. Seventeen patients from 2007 to 2009 underwent anterior debridement and fusion with a minimally invasive approach combined with posterior fixation via the Wiltse approach. Postoperative follow-up time was 24-41 months. Data included the patients' general information, microbiology, operative time, intraoperative blood loss, postoperative complications, intervertebral fusion rate, and preoperative and final follow-up scores for American Spinal Injury Association (ASIA) impairment, visual analogue scale (VAS), and Oswestry Disability Index (ODI). Ten patients had undergone a prior spinal invasive procedure, and 7 had hematogenous infection. The infected segments included L1-2, L2-3, L3-4, and L4-5 in 1, 2, 5, and 9 cases, respectively. Thirteen bacterial cultures were positive for Staphylococcus aureus (5 cases), Staphylococcus epidermidis (4), Streptococcus (3), and Escherichia coli (1). The operative time was 213.8±45.6 min, and the intraoperative blood loss was 180.6±88.1 mL. Postoperative complications consisted of urinary retention (2 cases), constipation (3), and deep vein thrombosis (2). On the final follow-up, VAS scores and ODIs were significantly lower than those of preoperation, while the ASIA grades improved. All the cases achieved good intervertebral bony fusion. Anterior debridement and fusion with a minimally invasive approach combined with posterior fixation via the Wiltse approach can successfully treat single-level lumbar pyogenic spondylodiscitis, with less trauma and reliable immobilization. It is a viable option for clinical application.
