RESUMO
Glioblastoma represents the most common aggressive primary brain tumour in adults. Changes in cognition, personality and in behaviour of patient as well as side effects of treatments cause unique challenges for providing care and may impact caregiver burden in different ways. This retrospective study included 45 patients with diagnosis of glioblastoma treated between January 2022 and June 2023 in two Neurosurgical Departments. We investigated the quality of life and the experiences of glioblastoma patients caregivers on the end-of-life phase using a validated questionnaire consisting of 38 questions related to the caregiver's view of the patient's terminal phase and another 26 questions regarding caregiver's experiences and emotions during the last three months of the patient's life. Fatigue, reduced consciousness and sadness were the most common patient's symptoms reported by their caregivers. The reported quality of life of caregivers was low and superimposable to the quality of life that they attributed to the patients. The burnout symptoms and feelings of insufficient information emphasize the urgent need for psychological support and training dedicated to caregivers. The end-of-life phases of glioblastoma patient may represent a critical factor that significantly affects not only the patient but also caregiver burden, caregiving tasks, and caregiver time. A urgent multidisciplinary support program is needed to face and improve caregivers burden.
RESUMO
INTRODUCTION: Magnetic resonance-guided focused ultrasound (MRgFUS) is a contemporary non-invasive ablative procedure that utilizes high- or low-intensity ultrasound, guided and monitored by magnetic resonance imaging (MRI). While MRgFUS has been established as an effective treatment for conditions like essential tremor and tremor-dominant Parkinson's disease, it has recently emerged as a safe and promising ablative minimally invasive procedure for the management of treatment-resistant psychiatric disorders. Indeed, despite the availability of various pharmacological and behavioral therapies, a subset of psychiatric patients remains refractory to conventional treatments. EVIDENCE ACQUISITION: To assess the feasibility and safety of MRgFUS in psychiatric disorders, a comprehensive literature search in PubMed and Scopus databases was conducted, resulting in the inclusion of five relevant articles in this review. EVIDENCE SYNTHESIS: While data on this innovative procedure are still limited, MRgFUS demonstrates potential as a safer and less invasive surgical technique for treating these disorders. CONCLUSIONS: Continued research efforts and data validation are imperative to establish MRgFUS as an additional, minimally invasive procedure for treatment-resistant psychiatric patients in the near future.
RESUMO
BACKGROUND/AIM: The glioblastomas, aggressive brain tumors with a poor prognosis, have drawn interest in their interaction with the glymphatic system-an emerging brain drainage network. This review explores the relationship between glioblastomas and the glymphatic system, aiming to elucidate their impact on disease progression. The aim of the study was to address the alterations in the glymphatic system in the presence of glioblastoma, and their implications for disease pathogenesis and prognosis. MATERIALS AND METHODS: Following PRISMA guidelines, we conducted a systematic literature review, identifying studies on the glymphatic system in glioblastomas. Four high-quality studies were selected based on stringent criteria. Data extraction involved categorizing key findings, and thematic analysis uncovered recurring patterns in glymphatic alterations associated with glioblastomas. RESULTS: Out of 356 studies, four meeting the high-quality criteria were included. These studies revealed modifications in lymphatic outflow, factors contributing to glymphatic dysfunction, impediments to cerebrospinal fluid drainage, and emerging roles in glioma management. The findings allow a comprehensive understanding of alterations within the glymphatic system in the presence of glioblastoma. CONCLUSION: The glymphatic system in glioblastomas exhibits changes, including diminished lymphatic outflow, disruptions and obstacles to fluid drainage, which represent new dimensions in glioma management. These alterations affect drug delivery, immunotherapy, and imaging interpretation. Future research should prioritize elucidating molecular mechanisms, developing therapeutic strategies, optimizing drug delivery, exploring immunotherapy, and translating findings into clinical practice.

PURPOSE: This systematic review aims to investigate the role of nuclear imaging techniques in detecting incidentalomas and their impact on patient management. METHODS: Following PRISMA guidelines, a comprehensive literature search was conducted from February to May 2022. Studies in English involving patients undergoing nuclear medicine studies with incidental tumor findings were included. Data on imaging modalities, incidentaloma characteristics, management changes, and follow-up were extracted and analyzed. RESULTS: Ninety-two studies involving 64.884 patients were included. Incidentalomas were detected in 611 cases (0.9%), with thyroid being the most common site. PET/CT with FDG and choline tracers showed the highest incidentaloma detection rates. Detection of incidentalomas led to a change in therapeutic strategy in 59% of cases. Various radiotracers demonstrated high sensitivity for incidentaloma detection, particularly in neuroendocrine tumors and prostate cancer. CONCLUSION: Nuclear imaging techniques play a crucial role in detecting incidentalomas, leading to significant changes in patient management. The high sensitivity of these modalities highlights their potential in routine oncology follow-up protocols. Future directions may include enhancing spatial resolution and promoting theranostic approaches for improved patient care.

BACKGROUND: In accordance with technique advancement and minimal invasiveness surgical approaches, the minipterional has progressively replaced the standard pterional approach for treatment of unruptured middle cerebral artery (MCA) aneurysms. Nowadays, multimodal intraoperative resources including microDoppler and microflow probes, indocyanine green videoangiography, and neurophysiologic monitoring constitute a fundamental prerequisite for increasing the safety of the clipping procedure. Our study investigated and compared in a single-center experience the effect of the evolution of a minimally invasive and multimodal approach in unruptured MCA aneurysm surgery by measuring postoperative complication rate, recovery time, and long-term neuropsychological and functional outcomes. METHODS: One hundred and thirty-one patients who underwent surgical treatment for unruptured MCA aneurysms at our institution were evaluated retrospectively. Patients' clinical, radiologic, and surgical reports were collected. Cognitive evaluation and quality of life were assessed through validated tests in telephone interviews. Patients who met the inclusion criteria were divided into 2 groups: "PT (pterional)" and "MPT (minipterional)." RESULTS: Ninety-two patients were included in the analysis. A significant reduction of postoperative complication rates and new-onset postoperative seizures was recorded in the MPT group (P value = 0.006). Severe cognitive deficits were lower in the MPT group, although without a clear statistical correlation. CONCLUSIONS: Decreased complication rates, faster recovery time, and a trend toward better cognitive and functional performances were documented for the MPT group of patients. In our experience, the minipterional approach with multimodality-assisted microsurgery reduced neurologic complications and recovery time and improved long-term cognitive outcome and quality of life.

Background: Ventriculoperitoneal (VP) shunt placement is one of the most performed procedures in neurosurgery to treat various types of hydrocephalus (HC). Immediate or late postoperative complications may quite commonly occur, especially in immunosuppressed patients, who are predisposed to develop rare and difficult-to-treat conditions. Case Description: Herein, we report the case of a 41-year-old female patient with a prior history of acute myeloid leukemia, followed by a tetra-ventricular acute HC due to a spontaneous non-aneurysmal subarachnoid hemorrhage. After an urgent external ventricular drainage placement, she underwent careful testing of "shunt dependency," which ended with a VP shunt placement. After 2 months, she presented at the emergency department with worsening abdominal pain and fever. She underwent a computed tomography scan with contrast administration, which has shown abscesses in the abdominal cavity. An urgent surgical revision of the VP shunt and antibiotics administration followed this. After inflammatory markers normalization, due to the high risk of post-infective peritoneal adherence and consequent impairment of cerebrospinal fluid absorption, a ventriculoatrial shunt was considered the most appropriate solution. Conclusion: Abdominal abscesses are a rare but subtle complication after VP shunt placement. Their management depends on etiology, patient clinical characteristics, and manifestations. Prompt interventions have been shown to improve clinical outcomes and optimize quality of life in such delicate patients.
RESUMO
BACKGROUND: Interruption of the fistulous point is the goal of treatment of spinal dural arteriovenous fistulas (dAVFs). Microsurgery remains a highly efficient treatment in terms of complete occlusion with the lowest risk of recurrence rate. It is reported that the hardest step involves finding the fistulous site itself, potentially extending surgical access and time and increasing potential postoperative surgical-related complications. The accurate preoperative detection of the shunt and spinal level together is crucial for guiding optimal, fast, and safe microsurgical treatment. METHODS: We describe a preoperative angiographic protocol for achieving a safe and simple resection of spinal dural arteriovenous fistulas based on a 6-year institutional experience of 42 patients who underwent minimally invasive procedures. Two illustrative cases are included to support the technical descriptions. RESULTS: The suspected artery associated with the vascular malformation of interest is studied in our angiographic protocol through nonsubtracted selective acquisitions in lateral projection. The resulting frames are reconstructed with three-dimensional rotational angiography. The implementation of the preoperative angiographic protocol allowed 100% of intraoperative identification of the fistulous point in all cases with the use of a minimally invasive approach. CONCLUSIONS: Nowadays, neurosurgeons advocate for minimally invasive procedures and procedures with low morbidity risk for treatment of spinal dural arteriovenous fistulas. Our preoperative approach for accurate angiographic localization of the fistulous point through nonsubtracted and three-dimensional reconstructed angiography allowed us to achieve safe and definitive occlusion of the shunt.

Ventriculitis and nosocomial meningitis caused by carbapenem-resistant Gram-negative and vancomycin-resistant Gram-positive bacteria represent a growing treatment challenge. A case of ventriculitis and bacteremia caused by carbapenem-resistant, KPC-producing Klebsiella pneumoniae and vancomycin-resistant Enterococcus faecium in a young woman with acute leukemia who was successfully treated with meropenem/vaborbactam (MVB), rifampicin, and linezolid is described in this paper. This case report emphasizes the importance of a multidisciplinary strategy, including infectious focus control, for the treatment of device-associated central nervous system (CNS) infections from multidrug-resistant bacteria. Considering the novel resistance patterns, more research on drug penetration into the central nervous system, as well as on the necessity of association therapies, is needed.
RESUMO
BACKGROUND: Skull metastases from follicular thyroid carcinoma (FTC) are infrequent but clinically significant, often presenting with localized pain, neurologic deficits, and cranial nerve dysfunction. Early detection and accurate diagnosis pose challenges due to their asymptomatic nature in some cases. METHODS: A systematic literature review, conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, identified and analyzed 15 relevant studies focusing on large skull metastases in FTC. Data extraction and synthesis included clinical presentation, diagnostic methods, treatment strategies, and patient outcomes. RESULTS: The systematic review encompassed 20 patients with secondary skull metastases from FTC, offering insights into the clinical diversity of this rare condition. Clinical presentations varied, with localized pain (70% of cases) and headaches being predominant symptoms. Imaging techniques, including computed tomography (CT) and magnetic resonance imaging (MRI), played a pivotal role in diagnosis. Surgical resection was considered in select cases, achieving complete or near-complete tumor removal in 30 to 50% of patients. Radiotherapy, including external beam radiation therapy (EBRT) and stereotactic radiosurgery (SRS), provided local control and symptom relief in 70 to 80% of cases. Systemic therapies, such as tyrosine kinase inhibitors (TKIs), showed promise in disease stabilization or regression (45% of patients). Prognosis remained poor, with a median overall survival of 6 to 12 months, reflecting an advanced and aggressive disease state. CONCLUSION: Managing secondary skull metastases from FTC requires a comprehensive approach, including surgical intervention, radiotherapy, and potential systemic therapies. The rarity of these metastases underscores the need for further research to establish standardized treatment guidelines, explore molecular profiling, and investigate immunotherapy and combination therapies, offering hope for improved outcomes in this challenging clinical scenario.
RESUMO
Background: Informed consent is a crucial aspect of modern medicine, but it can be challenging due to the complexity of the information involved. Mixed reality (MR) has emerged as a promising technology to improve communication. However, there is a lack of comprehensive research on the impact of MR on medical informed consent. The proposed research protocol provides a solid foundation for conducting future investigations and developing MR-based protocols that can enhance patients' understanding and engagement in the decision-making process. Methods: This study will employ a randomized controlled trial design. Two arms will be defined: MR-assisted informed consent (MRaIC) as the experimental arm and conventional informed consent (CIC) as the control arm consent, with 52 patients in each group. The protocol includes the use of questionnaires to analyze the anxiety levels and the awareness of the procedure that the patient is going to perform to study the impact of MRaIC versus CIC before medical procedures. Results: The study will evaluate the impact of MR on patients' information comprehension, engagement during the process of obtaining informed consent, emotional reactions, and consent decisions. Ethical concerns will be addressed. Conclusion: This study protocol provides a comprehensive approach to investigate the impact of MR on medical informed consent. The findings may contribute to a better understanding of the effects of MR on information comprehension, engagement during the process of obtaining informed consent, psychological experience, consent decisions, and ethical considerations. The integration of MR technology has the potential to enhance surgical communication practices and improve the informed consent process.
RESUMO
BACKGROUND/AIM: Intraventricular cerebral metastases (IVCM) are a rare but clinically significant subset of brain metastases. This systematic review aimed to provide a comprehensive analysis of IVCM by synthesizing current literature on epidemiology, clinical presentation, imaging features, pathophysiology, and treatment options. MATERIALS AND METHODS: A systematic literature search was conducted, identifying 11 relevant studies encompassing 11 studies encompassing 842 IVCM cases. Data regarding primary tumor origins, patient demographics, presenting symptoms, treatment modalities, and survival outcomes were analyzed. RESULTS: IVCM cases displayed a diverse range of primary tumor origins, with the kidney (27.4%), thyroid (21.6%), lung (19.8%), colon (11.7%), melanoma (8.4%), and breast ductal carcinoma (7.9%) being common sources. Patients presented with a wide spectrum of symptoms, including headaches (42.3%), nausea (31.5%), altered mental status (25.7%), neurological deficits (18.2%), and others. Treatment approaches varied, encompassing surgical resection (41.2%), radiation therapy (32.5%), chemotherapy (15.3%), and immunotherapy (7.9%). Overall survival was generally limited, with a mean duration of approximately 10.3 months (±8.7 months). The time to recurrence after treatment exhibited considerable variability. CONCLUSION: IVCM represents a challenging and underexplored metastatic disease. This systematic review underscores the need for further research to enhance our understanding of IVCM's pathophysiology and develop tailored diagnostic and treatment approaches. Such efforts are crucial to improving outcomes and the overall quality of life for patients facing this complex condition. The multidisciplinary nature of IVCM management, involving neurologists, neurosurgeons, oncologists, radiologists, and other healthcare professionals, is emphasized as essential for individualized patient care.

OBJECTIVE: The surgical approach to lesions near eloquent areas continues to represent a challenge for neurosurgeons, despite all of the sophisticated tools currently used. The goal of surgery in eloquent areas is to maintain a good oncofunctional balance, that is, to preserve neurological function and ensure maximum tumor resection. Among all the available tools, extended reality (used to describe both virtual reality [VR] and mixed reality) is rapidly gaining a pivotal role in such delicate lesions, especially in preoperative planning, and recently, even during the surgical procedure. VR creates a completely new world in which only digital components are present. Augmented reality (AR), using software and hardware to introduce digital elements into the real-world environment, enhances the human experience. In addition, mixed reality, a more recent technique, combines VR and AR by projecting virtual objects into the real world, allowing the user to interact with them. METHODS: A systematic literature review of the last 23.5 years was conducted (January 2000-June 2023) to investigate and discuss all progress related to the emerging role and use of these new technologies (VR, AR, and mixed reality), particularly in eloquent area lesions as a pre- and/or intraoperative tool. RESULTS: Five hundred eighty-four published studies were identified. After removing duplicates and excluding articles that did not meet the inclusion criteria, 21 papers were included in the systematic review. The use of AR or VR was fully analyzed, considering their roles both intraoperatively and for surgical planning. CONCLUSIONS: The increasing use of such innovative technologies has completely changed the way to approach a lesion, using 3D visualization to foster a better understanding of its anatomical and vascular characteristics.

OBJECTIVE: This study aimed to rigorously assess the accuracy of mixed-reality neuronavigation (MRN) in comparison with magnetic neuronavigation (MN) through a comprehensive phantom-based experiment. It introduces a novel dimension by examining the influence of blue-green light (BGL) on MRN accuracy, a previously unexplored avenue in this domain. METHODS: Twenty-nine phantoms, each meticulously marked with 5-6 fiducials, underwent CT scans as part of the navigation protocol. A 3D model was then superimposed onto a 3D-printed plaster skull using a semiautomatic registration process. The study meticulously evaluated the accuracy of both navigation techniques by pinpointing specific markers on the plaster surface. Precise measurements were then taken using digital calipers, with navigation conducted under three distinct lighting conditions: indirect white light (referred to as no light [NL]), direct white light (WL), and BGL. The research enlisted two operators with distinct levels of experience, one senior and one junior, to ensure a comprehensive analysis. The study was structured into two distinct experiments (experiment 1 [MN] and experiment 2 [MRN]) conducted by the two operators. Data analysis focused on calculating average and median values within subgroups, considering variables such as the type of lighting, precision, and recording time. RESULTS: In experiment 1, no statistically significant differences emerged between the two operators. However, in experiment 2, notable disparities became apparent, with the senior operator recording longer times but achieving higher precision. Most significantly, BGL consistently demonstrated a capacity to enhance accuracy in MRN across both experiments. CONCLUSIONS: This study demonstrated the substantial positive influence of BGL on MRN accuracy, providing profound implications for the design and implementation of mixed-reality systems. It also emphasized that integrating BGL into mixed-reality environments could profoundly improve user experience and performance. Further research is essential to validate these findings in real-world settings and explore the broader potential of BGL in a variety of mixed-reality applications.

Surgical treatment of neurovascular lesions like intracranial aneurysms, arteriovenous malformations and arteriovenous dural fistulas is still associated with high morbidity. Several recent studies are providing increasing insights into reliable tools to improve surgery and reduce complications. Inadvertent vessel compromise and incomplete occlusion of the lesion represent the most possible complications in neurovascular surgery. It is clear that direct visual examination alone does not allow to identify all instances of vessel compromise. Various modalities, including angiography, microvascular Doppler and neurophysiological studies, have been utilized for hemodynamics of flow vessels in proper clipping of the aneurysm or complete obliteration of the lesion. We intended to review the current knowledge about the intraoperative microvascular Doppler (iMDS) employment in the most updated literature, and explore the most recent implications not only in intracranial aneurysms but also in neurovascular lesions like arteriovenous malformations (AVMs) and arteriovenous dural fistulas (AVDFs). According to the PRISMA guidelines, systematic research in the most updated platform was performed in order to provide a complete overview about iMDS employment in neurovascular surgery. Twelve articles were included in the present paper and analyzed according to specific research areas. iMDS employment could represent a crucial tool to improve surgery in neurovascular lesions. The safety and effectiveness of the surgical treatment of neurovascular lesions like intracranial aneurysm and other neurovascular lesions like AVMs and AVDFs requires careful and accurate consideration regarding the assessment of anatomy and blood flow. Prognosis may depend on suboptimal or incomplete exclusion of the lesion.
RESUMO
Eloquent brain tumor surgery involves the delicate task of resecting tumors located in regions of the brain responsible for critical functions, such as language, motor control, and sensory perception. Preserving these functions is of paramount importance to maintain the patient's quality of life. Corticocortical evoked potentials (CCEPs) have emerged as a valuable intraoperative monitoring technique that aids in identifying and preserving eloquent cortical areas during surgery. This systematic review aimed to assess the utility of CCEPs in eloquent brain tumor surgery and determine their effectiveness in improving patient outcomes. A comprehensive literature search was conducted using electronic databases, including PubMed/Medline and Scopus. The search strategy identified 11 relevant articles for detailed analysis. The findings of the included studies consistently demonstrated the potential of CCEPs in guiding surgical decision making, minimizing the risk of postoperative neurological deficits, and mapping functional connectivity during surgery. However, further research and standardization are needed to fully establish the clinical benefits and refine the implementation of CCEPs in routine neurosurgical practice.

In the field of minimally invasive neurosurgery, microscopic transsphenoidal surgery (MTS) and endoscopic transsphenoidal surgery (ETS) have been widely accepted as a safe approach for pituitary lesions and, more recently, their indications have been extended to lesions at various skull base regions. It is mandatory during transsphenoidal surgery (TS) to identify key anatomical landmarks in the sphenoid sinus and distinguish them from the lesion. Over the years, many intraoperative tools have been introduced to improve the neuronavigation systems aiming to achieve safer and more accurate neurosurgical interventions. However, traditional neuronavigation systems may lose the accuracy of real-time location due to the discrepancy between the actual surgical field and the preoperative 2D images. To deal with this, augmented reality (AR)-a new sophisticated 3D technology that superimposes computer-generated virtual objects onto the user's view of the real world-has been considered a promising tool. Particularly, in the field of TS, AR can minimize the anatomic challenges of traditional endoscopic or microscopic surgery, aiding in surgical training, preoperative planning and intra-operative orientation. The aim of this systematic review is to analyze the potential future role of augmented reality, both in endoscopic and microscopic transsphenoidal surgeries.
RESUMO
Spinal cord injury (SCI) is a devastating neurological disorder that has a substantial detrimental impact on a person's quality of life. The estimated global incidence of SCI is 40 to 80 cases per million people and around 90% of cases are traumatic. Various etiologies can be recognized for SCI, and post-traumatic SCI represents the most common of these. Patients worldwide with SCI suffer from a persistent loss of motor and sensory function, which affects every aspect of their personal and social lives. Given the lack of effective treatments, many efforts have been made to seek a cure for this condition. In recent years, thanks to their ability to regenerate tissue and repair lost or damaged cells, much attention has been directed toward the use of stem cells (embryonic, induced pluripotent, mesenchymal, hematopoietic), aimed at restoring the functional integrity of the damaged spinal cord and improving a functional recovery including sensory and motor function. In this paper, we offer an overview of the benefits and drawbacks of stem cell therapy for SCI based on clinical evidence. This report also addresses the characteristics of various stem cell treatments, as well as the field's likely future. Each cell type targets specific pathological characteristics associated with SCI and demonstrates therapeutic effects via cell replacement, nutritional support, scaffolds, and immunomodulation pathways. SCI accompanied by complex pathological processes cannot be resolved by single treatment measures. Stem cells are associated with the adjustment of the expression of neurotrophic factors that help to achieve better nutrition to damaged tissue. Single-cell treatments have been shown in some studies to provide very minor benefits for SCI in multiple preclinical studies and a growing number of clinical trials. However, SCI damage is complex, and many studies are increasingly recognizing a combination approach such as physical therapy, electrical stimulation, or medication therapy to treatment.
