Traditionally, nonoperative management with long-term antibiotics and bed rest has been recommended as first-line treatment for most patients with postoperative discitis. A recent trend in treatment under a limited range of indications has been to perform surgical débridement followed by long-term administration of antibiotics. This descriptive study investigated whether transforaminal lumbar interbody débridement and fusion (TLIDF) combined with intravenous antibiotics is appropriate to manage postdiscectomy discitis. ⋯ Based on previously reported data and the findings of this study, we suggest that surgical intervention should be used in certain cases, as it can achieve better outcomes than conservative treatment. We recommend a novel single posterior approach with TLIDF and posterior pedicle screw instrumentation for management of postdiscectomy discitis.

Carotid atherosclerotic plaque occurs predominantly at the outer wall of the carotid sinus, and computational fluid dynamics (CFD) plays an important role in explaining plaque formation. The present study investigated the hemodynamic factors affecting carotid atherosclerotic stenosis. ⋯ Significantly decreased vascular WSS, dynamic pressure, strain rate, and total pressure gradient are key to atherosclerotic plaque formation at the carotid sinus.

Evidence is lacking concerning the myriad surgical techniques for type 1 Chiari malformation. This study evaluated the impact of arachnoid violation with tonsil thermocoagulation during surgical craniovertebral junction decompression. ⋯ For treatment of symptomatic type 1 Chiari malformation, craniovertebral junction decompression with arachnoid preservation (i.e., without tonsillar manipulation) seems more suitable than the addition of arachnoid opening and thermocoagulation of the tonsils.

This study aims to investigate the utility of 18F-fluoro-ethyl-tyrosine (18F-FET) positron emission tomography in surgical decision making in suspected glioma. ⋯ Lesions with TBRmax >2.5 should be considered suspicious for glioma and biopsy considered. Threshold TBRmax >3.0 is useful for differentiating high-grade glioma from low-grade glioma. This may be a particularly useful tool for directing management in eloquent areas, such as brainstem glioma.

Ewing's sarcoma family tumors (ESFTs) are the second most common malignancy in children and adolescents. The purpose of the present retrospective study was to evaluate the prognostic role of inflammatory biomarkers and preoperative D-dimer levels in patients with spinal ESFTs. ⋯ Our results have indicated that the preoperative D-dimer level is an effective prognostic factor with discriminatory ability for DFS and OS, superior to other indicators. Also, CAR was favorable prognostic factor for OS. Nomograms of DFS and OS can be recommended as practical models to evaluate the prognosis for patients with spinal ESFTs.
