Review
INTRODUCTION
Endoscopic surgery is a minimally invasive procedure that has been shown to relieve intradiscal pressure, irrigation of inflammatory factors, and visual debridement which are crucial for the successful treatment of spondylodiscitis. This study proposes a systematic review and meta-analysis to evaluate the effectiveness and safety of endoscopic treatment of thoracolumbar spondylodiscitis.
METHODS
Multiple databases were searched for studies involving thoracolumbar spondylodiscitis treated by endoscopic disc drainage with or without additional posterior fixation over the last twenty years. Studies that met the inclusion criteria, which included outcomes related to the percentage of cured infections, patient satisfaction, regression of inflammatory markers, and/or the percentage of adverse event rates, were included in the analysis. For each study, the percentage of patients who showed improvement or experienced an adverse event was abstracted and pooled in a meta-analysis.
RESULTS
Based on the search strategy and inclusion criteria, our systematic review and meta-analysis included 20 studies with 546 participants. The success rate was 89.4% (95% CI 83.1%-94.5%). The rate of major adverse events was 0.3%, while that of postoperative transient paresthesia 2.6% (95% CI 0.8%-5.1%). The recurrence rate was 1.7% (95% CI 0.3%-4.0%), and revision surgery was 8.5% (95% CI 3.8%-14.6%). The causative pathogen diagnosis rate was 73.9% (95% CI 67.7%-79.8%), while progression of deformity was 3.7% (95% CI 0.2%-9.8%), and spontaneous fusion was 40.1% (95% CI 11.0%-73.3%).
CONCLUSIONS
Endoscopic discectomy for thoracolumbar spondylodiscitis has been shown to be a safe technique with satisfactory clinical outcomes and a high causative pathogen identification rate.

Review
OBJECTIVE
Deciding the healing end point in spinal tuberculosis (STB) remains a controversial topic. The current systematic review aims to address the controversy existing in the literature to find a comprehensive method to assess healing in STB.
METHODS
A thorough literature search was carried out for studies with the assessment of healing parameters in STB. Data extraction was carried out manually, which included study characteristics and healing criteria evaluated in each study.
RESULTS
Qualitative analysis of 8 included studies showed that healing parameters were described in 3 domains: clinical, hematologic, and radiologic response of the patient to antitubercular chemotherapy. Each domain included various individual parameters, with clinical and radiologic assessment criteria being used in most of the studies. Improvement in terms of pain, constitutional symptoms, weight gain, neurology; variation in erythrocyte sedimentation rate and C-reactive protein; and changes in radiography, magnetic resonance imaging, and positron emission tomography/computed tomography were found to be promising predictors in the assessment of healing.
CONCLUSIONS
Radiologic response parameters emerged as the maximally used criteria to assess healing in STB. However, in the absence of any statistical analysis and an observed lag in radiologic response, the cumulative effect of all the parameters in 3 domains (clinical, hematologic, and radiologic) can be used to declare a spinal tubercular lesion nonhealing, healing, or healed.

BACKGROUND
Spondylodiscitis (SD), a rare disease in children, poses diagnostic challenges due to non-specific presenting symptoms, scarcity in incidence, and difficulty expressing pain in non-verbal children.
METHOD
A comprehensive search was conducted on three databases, including PubMed/Medline, Web of Science, and Scopus until March 2023. The inclusion criteria were studies that investigated the clinical characteristics, treatment, and complications of children's spondylodiscitis. Full text of cross-sectional and cohort studies were added. The quality assessment of cohort studies was conducted using the Newcastle-Ottawa Quality Assessment Scale. The search, screening, and data extraction were performed by two researchers independently.
RESULT
Clinical manifestations of discitis in children are nonspecific, such as back pain, fever, reduced ability or inability to walk or sit, limping, and reduced range of movements. The mean delay in the time of diagnosis was 4.8 weeks. The most affected site of all the studies was the lumbar spine. 94% of studies reported increased inflammatory markers such as white blood cell count, C-reactive protein, and erythrocyte sedimentation rate. Less than 30% of patients had positive blood cultures and biopsy findings. The most common microbiological results (64%) were Staphylococcus Aureus and Kingella kingae. In radiographic evaluation, intervertebral disk narrowing, lumbar lordosis reduction, loss of disk height, and destruction of the vertebral body have been reported. In all studies, antibiotic therapy was initiated; in 52% immobilization was employed, and 29% of studies reported surgery was performed, and the follow-up period differed from 1.5 months to 156 months. 94% of studies reported complications such as vertebral body destruction, back pain, kyphosis, reduced range of movement, scoliosis, and neurological complications.
CONCLUSION
Spondylodiscitis is an uncommon, heterogeneous, multifactorial disease with resulting difficult and delayed diagnosis. Due to its morbidity, it is essential to investigate children with refusal to walk, gait disturbances, or back pain, particularly when associated with elevated inflammatory markers.

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

Meta-Analysis
Spondylodiscitis is the commonest spine infection, and pyogenic spondylodiscitis is the most common subtype. Whilst antibiotic therapy is the mainstay of treatment, some advocate that early surgery can improve mortality, relapse rates, and length of stay. Given that the condition carries a high mortality rate of up to 20%, the most effective treatment must be identified. We aimed to compare the mortality, relapse rate, and length of hospital stay of conservative versus early surgical treatment of pyogenic spondylodiscitis. All major databases were searched for original studies, which were evaluated using a qualitative synthesis, meta-analyses, influence, and regression analyses. The meta-analysis, with an overall pooled sample size of 10,954 patients from 21 studies, found that the pooled mortality among the early surgery patient subgroup was 8% versus 13% for patients treated conservatively. The mean proportion of relapse/failure among the early surgery subgroup was 15% versus 21% for the conservative treatment subgroup. Further, it concluded that early surgical treatment, when compared to conservative management, is associated with a 40% and 39% risk reduction in relapse/failure rate and mortality rate, respectively, and a 7.75 days per patient reduction in length of hospital stay (p < 0.01). The meta-analysis demonstrated that early surgical intervention consistently significantly outperforms conservative management in relapse/failure and mortality rates, and length of stay, in patients with pyogenic spondylodiscitis.
