Background: Glioblastoma multiforme (GBM) is a highly aggressive form of brain cancer. This study investigated the clinical predictive value of heat shock protein β1 (HSPB1) in patients with GBM.
Methods: A correlation was established between HSPB1 expression and GBM progression using data from The Cancer Genome Atlas (TCGA) dataset, Chinese Glioma Genome Atlas dataset, Gene Expression Omnibus dataset, and Human Protein Atlas database. A survival analysis was conducted and an HSPB1-based nomogram was constructed to evaluate the prognostic value of HSPB1 in patients with GBM.
Results: Based on TCGA data mining, we discovered that HSPB1 was significantly elevated in patients with GBM and may reflect their response to immunotherapy. In survival analysis, it appeared to have a predictive role in the prognosis of patients with GBM. Five signaling pathways were significantly enriched in the high HSPB1 expression phenotype according to the gene set enrichment analysis. In addition, a significant association was found between HSPB1 expression and immune checkpoints, tumor immune infiltration, tumor immune microenvironment, and immune cell markers in glioma. Overall, our results suggest that HSPB1 may regulate the function of immune cells, serve as a new immunotherapy target, and predict the response to immunotherapy in patients with GBM.
Conclusion: HSPB1 appears to serve as a potential predictor of the clinical prognosis and response to immunotherapy in patients with GBM. It may be possible to identify patients who are likely to benefit from immunotherapy by assessing the expression level of HSPB1.

Background: The present study aimed to compare the clinical and radiologic outcomes of oblique lumbar interbody fusion (OLIF) combined with lateral screw fixation and minimally invasive transforaminal lumbar interbody fusion (Mis-TLIF) for the treatment of single-level degenerative lumbar spondylolisthesis (DLS).
Methods: Data regarding clinical and radiologic outcomes for single-level DLS treated using OLIF combined with lateral screw fixation or Mis-TLIF between November 2017 and June 2020 were retrospectively analyzed.
Results: Seventy-five patients with single-level DLS (≥2 years' follow-up) were included and divided into two groups according to the surgical method used: OLIF (n = 33) and Mis-TLIF (n = 42). Operative time, intraoperative blood loss, and length of hospital stay were significantly lower in the OLIF group than that in the Mis-TLIF group. There were no significant differences in preoperative low back pain (LBP), leg pain (LP), visual analog scale (VAS) scores, and Oswestry Disability Index (ODI) between the two groups, although the OLIF group had significantly lower LBP VAS scores at 1, 3, and 6 months postoperatively. Additionally, the LP VAS score was significantly lower in the Mis-TLIF group than that in the OLIF group at 1 month postoperatively, and the ODI of the OLIF group at 3 months postoperatively was significantly lower than that of the Mis-TLIF group. There was no significant difference in the preoperative and postoperative lumbar lordosis angles between the two groups, whereas the postoperative surgical segmental lordosis angle and disk height (at 1, 6, 12, and 24 months) in the OLIF group were significantly higher than those in the Mis-TLIF group. Additionally, there was no significant difference in complication rates between the two groups (18.2% in the OLIF group vs. 11.9% in the Mis-TLIF group; p = 0.520).
Conclusion: OLIF combined with lateral screw fixation yielded better clinical and radiologic outcomes than Mis-TLIF in patients with single-level DLS.

Background: Brain arteriovenous malformations (bAVMs) are abnormal vascular connections with direct arteriovenous shunts, generally symptomatic in the adult life. However, a small number of bAVMs may manifest in pediatric patients, with higher bleeding risk and mortality rates when compared to adults. The purpose of this study is to review our experience with endovascular treatment of bAVMs in pediatric patients.
Methods: This is a retrospective analysis of all bAVMs in pediatric patients (0-18 years) who underwent diagnostic digital subtraction angiography (DSA) at our institution from January 2010 to June 2021.
Results: Twenty-six patients met the inclusion criteria, of which 12 underwent endovascular treatment. Treated patients had a mean age of 10.25 years and 58% were females. Complete angiographic exclusion was achieved in five (42%) patients with endovascular treatment. Five patients with residual bAVM after embolization needed adjuvant therapy with surgery (n = 3) or stereotactic radiosurgery (SRS; n = 2). Two patients are still undergoing embolization sessions. Procedure-related complications occurred in two patients (17%) and included small vessel perforation and an occipital ischemic stroke. Two patients showed bAVM recurrence on follow-up (17%) and subsequently underwent SRS (n = 1) or surgery (n = 1), both resulting in complete bAVM exclusion. All patients had a modified Rankin scale (mRS) score of 0 to 2 on follow-up.
Conclusion: Our experience supports the effectiveness and safety of endovascular treatment of bAVM in selected pediatric patients. A multidisciplinary approach combining surgery and SRS is warranted to achieve higher complete bAVM obliteration rates. Long-term follow-up is important as these lesions may show recurrence over time, especially in the pediatric population.

Background: Hypoxia is an important clinical feature of glioblastoma (GBM), which regulates a variety of tumor processes and is inseparable from radiotherapy. Accumulating evidence suggests that long noncoding RNAs (lncRNAs) are strongly associated with survival outcomes in GBM patients and modulate hypoxia-induced tumor processes. Therefore, the aim of this study was to establish a hypoxia-associated lncRNAs (HALs) prognostic model to predict survival outcomes in GBM patients.
Methods: LncRNAs in GBM samples were extracted from The Cancer Genome Atlas database. Hypoxia-related genes were downloaded from the Molecular Signature Database. Co-expression analysis of differentially expressed lncRNAs and hypoxia-related genes in GBM samples was performed to determine HALs. Six optimal lncRNAs were selected for building HALs models by univariate Cox regression analysis.
Results: The prediction model has a good predictive effect on the prognosis of GBM patients. Meanwhile, LINC00957 among the six lncRNAs was selected and subjected to pan-cancer landscape analysis.
Conclusion: Taken together, our findings suggest that the HALs assessment model can be used to predict the prognosis of GBM patients. In addition, LINC00957 included in the model may be a useful target to study the mechanism of cancer development and design individualized treatment strategies.

We present a rare case of Listeria monocytogenes (LM) rhombencephalitis with the formation of multifocal abscesses in a young immunocompetent patient. His initial symptoms of dizziness, headache, and feeling generally unwell were put down to a coincidental coinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The unfortunate rapid progression to trigeminal, hypoglossal, vagal, facial, and abducens nuclei palsies, and then an acquired central hypoventilation syndrome, known as Ondine's curse, required a prolonged intensive care unit (ICU) stay, and prolonged mechanical ventilation. As they continued to deteriorate despite targeted antibiotic treatment, surgical drainage of the abscesses was seen as the only meaningful available treatment option left to contain the disease. Postoperatively, the patient's strength rapidly improved as well as the severity of the cranial nerve palsies. After prolonged rehabilitation, at 3 months of follow-up, the patient was weaned off mechanical ventilation, independently mobile, and was left with only minor residual neurologic deficits. This case highlights a number of interesting findings only touched upon in current literature including the route of entry of LM into the central nervous system, the rare entity of acquired central hypoventilation syndrome, and finally the use of surgical intervention in cerebral LM infections.

Background: The effects of sleep deprivation on surgical performance have been well documented. However, reports on the effects of sleep deprivation on microneurosurgery are limited. This study aimed to investigate the effects of sleep deprivation on microneurosurgery.
Methods: Ten neurosurgeons participated in the anastomosis of a vessel model using a microscope in sleep-deprived and normal states. We evaluated the procedure time (PT), stitch time (ST), interval time (IT), number of unachieved movements (NUM), leak rate, and practical scale for anastomosis quality assessment. Each parameter was compared between normal and sleep-deprived states. Subanalyses were performed on the two groups based on PT and NUM under the normal state (proficient and nonproficient groups).
Results: Although no significant differences were noted in PT, ST, NUM, leak rate, or practical scale, IT was significantly prolonged under sleep deprivation compared with the normal state (mean: 258.8 ± 94.0 vs. 199.3 ± 74.9 seconds; p = 0.02). IT was significantly prolonged under sleep deprivation in the nonproficient group based on both PT and NUM (PT: 234.2 ± 71.6 vs. 321.2 ± 44.7 seconds, p = 0.04; NUM: 173.3 ± 73.6 vs. 218.7 ± 97.7; p = 0.02), whereas no significant difference was observed in the proficient group (PT: 147.0 ± 47.0 vs. 165.3 ± 61.1 seconds, p = 0.25; NUM: 173.3 ± 73.6 vs. 218.7 ± 97.7; p = 0.25).
Conclusions: Although IT was significantly prolonged under sleep deprivation in the nonproficient group, there was no decline in performance skills in either the proficient or nonproficient group. The effect of sleep deprivation may require caution in the nonproficient group, but it is possible that certain microneurosurgical outcomes can be achieved under sleep deprivation.
背景:睡眠不足对外科手术效果的影响已有详细记载。然而,有关睡眠不足对微神经外科影响的报道却很有限。本研究旨在调查睡眠不足对微创神经外科手术的影响:十名神经外科医生分别在睡眠不足和正常状态下使用显微镜参与了血管模型的吻合手术。我们评估了手术时间(PT)、缝合时间(ST)、间隔时间(IT)、未完成动作次数(NUM)、渗漏率和吻合质量评估实用量表。每个参数都在正常和睡眠不足状态下进行了比较。根据正常状态下的 PT 和 NUM 对两组(熟练组和不熟练组)进行了子分析:结果:虽然在 PT、ST、NUM、泄漏率或实用量表方面没有发现明显差异,但与正常状态相比,睡眠不足状态下的 IT 显著延长(平均值:258.8 ± 94.0 对 199.3 ± 74.9 秒;P = 0.02)。根据 PT 和 NUM,非熟练组的 IT 在睡眠剥夺状态下明显延长(PT:234.2 ± 71.6 vs. 321.2 ± 44.7 秒,p = 0.04;NUM:173.3 ± 73.6 vs. 218.7 ± 97.7 秒,p = 0.02)。7;p = 0.02),而熟练组则无明显差异(PT:147.0 ± 47.0 vs. 165.3 ± 61.1 秒,p = 0.25;NUM:173.3 ± 73.6 vs. 218.7 ± 97.7;p = 0.25):结论:虽然在睡眠不足的情况下,非熟练组的 IT 时间明显延长,但熟练组和非熟练组的表现技能都没有下降。在非熟练组中,睡眠不足的影响可能需要谨慎对待,但在睡眠不足的情况下,可能会取得某些微神经外科效果。

Background: Hemostasis in neurosurgery is crucial to patient and surgery outcomes, with many techniques developed for this. One area that is not appropriately characterized despite continuous anecdotal evidence the temperature of the irrigation fluid (IF) used and its effects on stemming hemorrhages. Given the ubiquitous use of IF in neurosurgery for clearing blood from the surgical field, it is important to explore its role as a hemostat and whether or not the temperature of the IF influences its hemostatic capacity. This review explored the literature for an optimal IF temperature for hemostasis in neurosurgery.
Methods: Database searches were conducted using MEDLINE, Scopus, Web of Science, and CINAHL, with citation chaining occurring where applicable. Standard terms around neurosurgery, hemostasis, and irrigation were used.
Results: Seven articles were identified. No optimal temperature for hemostasis could be confidently synthesized from the literature owing to lack of primary investigation on the subject. After collating available information into common themes, it is suggested that that temperatures >38°C are preferred.
Conclusion: The literature in this area is limited. Despite a lack of applicable systematic investigation on the topic, by exploring the physiology of hemostasis and IF, best practice guidelines for IF, and the literature on the role of the temperature of IF in other surgical specialties, it is suggested that a temperature in the range of 38 to 40°C would be most applicable to a value optimal for neurosurgery.
背景:神经外科手术中的止血对患者和手术效果至关重要,为此开发了许多技术。尽管不断有轶事证据表明灌洗液(IF)的温度及其对止血的影响,但仍有一个领域没有得到适当的描述。鉴于 IF 在神经外科手术中普遍用于清除手术区域的血液,因此探讨其作为止血钳的作用以及 IF 的温度是否会影响其止血能力非常重要。本综述探讨了神经外科止血的最佳 IF 温度的文献:方法:使用 MEDLINE、Scopus、Web of Science 和 CINAHL 进行数据库检索,适当时进行引文链检索。结果:共发现 7 篇文章:结果:共发现七篇文章。由于缺乏对这一主题的初步调查,无法从文献中确定止血的最佳温度。在将现有信息整理为共同主题后,建议首选温度 >38°C:该领域的文献有限。尽管缺乏相关的系统性研究,但通过探讨止血和中频炉的生理学、中频炉最佳实践指南以及其他外科专业中频炉温度作用的文献,我们认为 38 至 40°C 的温度范围最适合神经外科的最佳值。

This review explored the literature for an optimal IF temperature for hemostasis in neurosurgery.</p><p><strong>Methods: </strong> Database searches were conducted using MEDLINE, Scopus, Web of Science, and CINAHL, with citation chaining occurring where applicable. Standard terms around neurosurgery, hemostasis, and irrigation were used.</p><p><strong>Results: </strong> Seven articles were identified. No optimal temperature for hemostasis could be confidently synthesized from the literature owing to lack of primary investigation on the subject. After collating available information into common themes, it is suggested that that temperatures >38°C are preferred.</p><p><strong>Conclusion: </strong> The literature in this area is limited. Despite a lack of applicable systematic investigation on the topic, by exploring the physiology of hemostasis and IF, best practice guidelines for IF, and the literature on the role of the temperature of IF in other surgical specialties, it is suggested that a temperature in the range of 38 to 40°C would be most applicable to a value optimal for neurosurgery.</p>","PeriodicalId":16544,"journal":{"name":"Journal of neurological surgery.

Superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery for internal carotid artery (ICA) occlusive disease necessarily requires sufficient external carotid artery (ECA) blood flow. Surgical bypass is therefore precluded if there is common carotid artery (CCA) occlusion. Here we present two such cases: one patient had a CCA occlusion and the other had an ICA occlusion and ECA stenosis. Both had failed medical management, and were therefore treated with angioplasty and stenting of the ECA, followed by STA-MCA bypass. We describe the clinical and radiologic outcomes of these cases, and remark on the potential pitfalls associated with this novel approach.

Background: Isthmic spondylolisthesis most commonly occurs in the lumbosacral junction and can cause backpain and radicular pain as well as stiffness with progressive immobilization, with a negative impact on an individual's ability to work and quality of life. Multiple operative treatments are currently available. This study aims to compare complications, demography, and clinical features between anterior lumbar interbody fusion (ALIF) and posterior lumber body fusion (PLIF) in the operative treatment in isthmic spondylolisthesis.
Methods: An analysis of data from the German spine registry (Deutsche Wirbelsäulengesellschaft [DWG]-Register) of patients who underwent operative treatment (PLIF and ALIF) for isthmic spondylolisthesis in the sacrolumbar junction in 170 departments between January 2017 and May 2021 was performed. Age, gender, American Society of Anesthesiologists (ASA) score, surgical approach, smoker/nonsmoker, as well as severeness of the spondylolisthesis according to the Meyerding classification were evaluated.
Results: In total, 602 patients undergoing fusion in L5/S1 were identified in the registry, n = 570 PLIF (group 1) and n = 32 ALIF (group 2). A significant difference in the ASA score between the two groups was noted; group 1 had more patients suffering a more debilitating disease in comparison to group 2. There was no significant difference in gender, grade of spondylolisthesis, age, or smoking status. Significant differences were found in operative and postoperative variables and complications (fusion material, dura injury).
Conclusion: No difference was found between the two procedures in terms of symptomatic benefit of patients who underwent either ALIF or PLIF. According to the DWG Register, PLIF was the preferred method to treat isthmic spondylolisthesis in the sacrolumbar junction in Germany. To compare these two spine fusion techniques, further studies with an adequate sample size and follow-up period are required.

Varicella-zoster virus (VZV) is a deoxyribonucleic acid (DNA) virus that causes both primary and recurrent viral infections. Herpes zoster (HZ), also known as shingles, is a unique condition that is induced by VZV reactivation. Neuropathic pain, malaise, and sleep disruption are prodromal symptoms in such cases. Postherpetic trigeminal neuralgia is a neuropathic pain caused by VZV infection of the trigeminal ganglion or branches, which remains or reappears after herpes crusting. In this report, we present a case of post-herpetic trigeminal neuralgia of the V2 branch, exhibiting findings of unusual involvement of the trigeminal nerve. Notably, the patient was treated using electrodes placed through the foramen ovale.
