Degenerative cervical myelopathy (DCM) is a leading cause of nontraumatic spinal cord injury. Surgery aims to arrest neurological decline and improve conditions, but controversies surround risks and benefits in elderly patients, outcomes in mild myelopathy, and the risk of adjacent segment disease (ASD). ⋯ Most myelopathic patients improve after anterior cervical discectomy and fusion. Elderly patients show a lower improvement and higher complication rates than their younger counterparts. ASD rates are low, and younger patients with preexisting cranial level alterations are more susceptible.

Hydrocephalus, a major complication in tuberculous meningitis (TBM) patients, often necessitates treatment via ventriculoperitoneal shunt (VPS). However, post-VPS, some patients develop a complication called contralateral isolated lateral ventricle (CILV), leading to persistent hydrocephalus symptoms. This study aims to evaluate cerebrospinal fluid (CSF) parameters in predicting CILV occurrence post-VPS in adult TBM patients. ⋯ The study identified elevated ADA levels and decreased glucose levels in CSF as potential risk factors for CILV development in adult TBM patients post-VPS. These findings suggest the necessity for more tailored surgical approaches, in patients with altered CSF parameters to mitigate the risk of CILV.

Review Meta Analysis
Meta-Analysis of the Efficacy of Raman Spectroscopy and Machine-Learning-Based Identification of Glioma Tissue.
Intraoperative Raman spectroscopy (RS) has been identified as a potential tool for surgeons to rapidly and noninvasively differentiate between diseased and normal tissue. Since the previous meta-analysis on the subject was published in 2016, improvements in both spectroscopy equipment and machine learning models used to process spectra may have led to an increase in RS efficacy. Therefore, we decided to conduct a meta-analysis to determine the efficacy of RS when differentiating between glioma tissue and normal brain tissue. ⋯ Finally, meta-analysis for sensitivity and specificity of RS for glioma tissue showed high heterogeneity (I2 = 99.37% and 98.21%, respectively) and yielded an overall sensitivity of 95.3% (95% confidence interval: 91.0%-99.6%) and an overall specificity of 71.2% (95% confidence interval: 54.8%-87.6%). Calculation of a summary receiver operating curve yielded an overall area under the curve of 0.9265. Raman spectroscopy represents a promising tool for surgeons to quickly and accurately differentiate between healthy brain tissue and glioma tissue.
