Impact of collagen matrix on reconstructive material selection and postoperative complications in endoscopic endonasal skull base surgery.
The aim of this study was to investigate the impact of collagen matrix on reconstructive material selection and postoperative complications in endoscopic endonasal skull base surgery. ⋯ Collagen matrix implementation significantly decreased autologous graft harvesting without increasing postoperative CSF leakage, contributing to less invasive surgery.

Safety of the immediate use of nonsteroidal anti-inflammatory drugs after adult craniotomy for tumor.
Poor pain control has a negative impact on postoperative recovery and patient satisfaction. However, overzealous pain management, particularly with opioids, can confound serial neurological assessments, increase morbidity, and predispose patients to long-term dependence. Nonsteroidal anti-inflammatory drugs (NSAIDs) are effective in treating postoperative pain and can limit opioid intake, but their use has been limited in patients undergoing craniotomy for brain tumor resection due to concerns of an increased hemorrhage risk. Herein, the authors aim to 1) address the safety of NSAID use in the immediate postoperative setting and 2) determine whether NSAID administration decreases opioid use following craniotomy for tumor resection in adult patients. ⋯ Postoperative NSAID use following craniotomy for tumor resection was not associated with an increased risk of hemorrhage requiring a return to the operating room. The authors noted higher opioid use in the patients treated with NSAIDs, which may reflect underlying reasons for the decision to treat patients with NSAIDs in the immediate postoperative period. These data warrant further investigation of NSAIDs as a safe, opioid-sparing postoperative pain management strategy in patients with normal kidney function who are undergoing intracranial tumor resection.

The correlation of cerebral arteriovenous malformation flow measured by quantitative MR angiography on MR-detected arteriovenous malformation microhemorrhage.
The objective of this study was to assess the relationship of arteriovenous malformation (AVM) blood flow measured by quantitative MR angiography (QMRA) in nonruptured AVMs with MR-detected microhemorrhage. ⋯ This study represents the first to examine the association between flow measurements on QMRA with microhemorrhage in unruptured AVMs. Higher AVM flow, venous anomaly, arterial ectasia, and diffuse AVM nidus were related to a higher likelihood of AVM microhemorrhage. Higher AVM flow was present in AVMs with venous anomalies, a diffuse nidus, and arterial ectasia, indicating a possible interaction between these angioarchitectural findings, AVM flow, and microhemorrhage. These findings suggest a relationship between higher AVM flow and the risk of microhemorrhage.

Effectiveness and safety of MR-guided focused ultrasound thalamotomy in patients with essential tremor and low skull density ratio: a study of 101 cases.
The objective was to investigate the effectiveness and safety of MR-guided focused ultrasound (MRgFUS) treatment in patients with essential tremor, particularly those with low skull density ratio (SDR) and including those with very low SDR, and to identify the factors influencing treatment effectiveness and to provide insights into therapeutic approaches for patients with lower SDR. ⋯ This study suggested that MRgFUS is effective and safe for patients with medication-resistant essential tremor, including those with very low mean SDR. However, the very low-SDR group had insufficient temperature elevation at the target site compared with the high-SDR group, suggesting the need for a different strategy. Notably, with careful adjustments and considerations, positive outcomes can still be achieved in patients with very low SDR. Therefore, very low SDR should not be considered an absolute exclusion criterion because it is expected to increase the number of patients who benefit from MRgFUS.

The number of women graduating from United States medical schools has reached parity with that of men. However, persistent inequalities and barriers have slowed the pace toward equity in application and representation in neurosurgery residency despite initiatives to increase female representation. The objective of the present study was to assess the advancement of gender parity within neurosurgery residency programs. Additionally, the study aimed to analyze the pipeline dynamics by investigating the effects of attrition on women in neurosurgery, as well as exploring the patterns of female applications to neurosurgery residency programs versus other surgical specialties. ⋯ Neurosurgery continues to struggle with the recruitment of female medical students even as parity has been reached for female medical school matriculants. Greater effort is needed to recruit and retain female applicants to neurosurgery, including increased transparency in match and attrition metrics.
