Letter to the Editor: Intraoperative microelectrode recording during asleep deep brain stimulation of subthalamic nucleus for Parkinson disease: a case series with systematic review of the literature.

This letter discusses the recent study by Izzo et al., which explored intraoperative microelectrode recording (MER) during asleep deep brain stimulation (DBS) of the subthalamic nucleus for Parkinson's disease. The study's integration of a systematic review positions its findings within the broader context of neurosurgical advances. Highlighting the practicality and patient comfort of the frameless technique under general anesthesia, it emphasizes the significance of MER in optimizing electrode placement, thereby potentially enhancing patient outcomes. The letter suggests future research directions, including randomized clinical trials, to assess the clinical benefits of this methodology further.

Letter to the editor: "Association of hemoglobin drift and outcomes in patients with aneurysmal subarachnoid hemorrhage".

This letter commends the study by Wang et al. on the association between in-hospital hemoglobin (Hb) drift and outcomes in aneurysmal subarachnoid hemorrhage (aSAH) patients undergoing surgical clipping. The study's findings highlight the importance of vigilant Hb monitoring and timely interventions. Future research directions include exploring interventions to minimize Hb drift, such as preoperative optimization and aggressive transfusion protocols. Comparative studies and multi-center approaches could further validate these findings, enhancing the generalizability and applicability of the results. This research represents a significant advancement in neurosurgical postoperative management.

Letter to the Editor: "The relationship between imaging features, therapeutic response, and overall survival in pediatric diffuse intrinsic pontine glioma".

This letter to the editor discusses the findings of Yu et al. (2024), which highlight the prognostic significance of volumetric assessments over cross-product measurements in pediatric diffuse intrinsic pontine glioma (DIPG). The study's methodology enhances precision in monitoring therapeutic responses, offering insights into treatment adjustments based on detailed imaging features. Emphasizing the value of volumetric MRI, this letter suggests its potential to improve surgical planning and therapeutic strategies, thereby optimizing patient management. This approach could revolutionize treatment paradigms, emphasizing personalized care through advanced imaging techniques.
