BACKGROUND: Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near-infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients. OBJECTIVES: To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with blinded or no cerebral oxygenation monitoring, or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of cerebral oxygen desaturation events (CDEs), neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay)...

BACKGROUND: Evidence for repeat computed tomography (CT) in minor traumatic brain injury (mTBI) patients with intracranial pathology is scarce. The aim of this study was to investigate the utility of clinical cognitive assessment (COG) in defining the need for repeat imaging. METHODS: COG performance was compared with findings on subsequent CT, and need for neurosurgery in mTBI patients (GCS 13-15 and positive CT findings). RESULTS: Of 152 patients, 65...

Many of the currently available treatments for obsessive-compulsive and related disorders (OCRDs) such as pharmacotherapy augmentation strategies, partial hospitalization programs, deep brain stimulation, and neurosurgery are efficacious for individuals suffering from more severe forms of these conditions. Unfortunately, the application of these treatments in milder forms of illness and subclinical samples, which affect a substantial portion of the population, is not justifiable by their costs (e.g. cognitive-behavioral therapy) and/or potential for side effects (serotonin-reuptake inhibitors associated sexual side effects)...

The field of non-invasive stimulation of the cerebellum is quickly expanding. The anatomical structure of the cerebellum with a high density of neurons in the superficial layer, its electrical properties, and its participation in numerous closed-loop circuits involved in motor, cognitive, and affective operations both in children and in adults make of the cerebellum a target with very high potential for neuromodulation of both cerebellar and extra-cerebellar disorders, in neurology, psychiatry, and neurosurgery...

Image-guided surgery (IGS) has allowed for more minimally invasive procedures, leading to better patient outcomes, reduced risk of infection, less pain, shorter hospital stays and faster recoveries. One drawback that has emerged with IGS is that the surgeon must shift their attention from the patient to the monitor for guidance. Yet both cognitive and motor tasks are negatively affected with attention shifts. Augmented reality (AR), which merges the realworld surgical scene with preoperative virtual patient images and plans, has been proposed as a solution to this drawback...

During the past few decades, Chinese endoscopic neurosurgery has achieved rapid development that has been synchronous with the rest of the world. The development history of Chinese endoscopic neurosurgery can be divided into three stages as follows: cognition and initial stage (1964-1995), exploration and maturity stage (1995-2006) and rapid development and promotion stage (2006-present). In the first stage, we mainly began to become aware of endoscopic neurosurgery from the translation and review of foreign literature...

Traumatic brain injury (TBI) disrupts the normal function of the brain. This condition can adversely affect a person's quality of life with cognitive, behavioral, emotional, and physical symptoms that limit interpersonal, social, and occupational functioning. Although many systems exist, the simplest classification includes mild, moderate, and severe TBI depending on the nature of injury and the impact on the patient's clinical status. Patients with TBI require prompt evaluation and multidisciplinary management...

BACKGROUND: The optimal treatment for low-grade gliomas remains controversial. Neurosurgery, radiotherapy, and chemotherapy are the main treatment options. Despite advances in oncology, there are still a lot of uncertainties, and the optimal sequences, combinations, and timings of these procedures have not yet been optimized. It is still unclear whether temozolomide can replace effective, but toxic PCV chemotherapy (procarbazine, lomustine, vincristine) and whether temozolomide can be used upfront alone instead of radiotherapy alone...

OBJECTIVE Cerebral mapping for surgical planning and operative guidance is a challenging task in neurosurgery. Pediatric patients are often poor candidates for many modern mapping techniques because of inability to cooperate due to their immature age, cognitive deficits, or other factors. Resting-state functional MRI (rs-fMRI) is uniquely suited to benefit pediatric patients because it is inherently noninvasive and does not require task performance or significant cooperation. Recent advances in the field have made mapping cerebral networks possible on an individual basis for use in clinical decision making...

BACKGROUND: Patient-reported preoperative factors hold promise in improving the prediction of postoperative adverse events, but they have been poorly studied. OBJECTIVE: To study the role of patient-reported factors in the preoperative risk stratification of elective craniotomy patients. METHODS: A prospective, unselected cohort of 322 adult patients underwent elective craniotomy in Helsinki, Finland. We preoperatively recorded the American Society of Anesthesiologists (ASA) score, Helsinki ASA score, and 3 questionnaire-based patient-reported factors including overall health status, ability to climb 2 flights of stairs, and cognitive function (Test Your Memory test)...

To determine the spatiotemporal relationships among intrinsic networks of the human brain, we recruited seven neurosurgical patients (four males and three females) who were implanted with intracranial depth electrodes. We first identified canonical resting-state networks at the individual subject level using an iterative matching procedure on each subject's resting-state fMRI data. We then introduced single electrical pulses to fMRI pre-identified nodes of the default network (DN), frontoparietal network (FPN), and salience network (SN) while recording evoked responses in other recording sites within the same networks...

Contrary to common psychosurgical practice in the 1950s, Dr. Jean Talairach had the intuition, based on clinical experience, that the brain connectome and neuroplasticity had a role to play in psychosurgery. Due to the remarkable progress of pharmacology at that time and to the technical limits of neurosurgery, these concepts were not put into practice. Currently, these concepts are being confirmed by modern techniques such as neuroimaging and computational neurosciences, and could pave the way for therapeutic innovation in psychiatry...

This article describes the distinctive function of the pediatric clinical research nurse (CRN) in the anesthesia setting. The pediatric CRN in anesthesia acts as a liaison between families and the research team and is the major nexus between the principal investigator or anesthesiologist on a study, and the collaborating surgeons from many different departments. This is unique because the CRNs collaborate with physicians in specialties that can include plastics, urology, neurosurgery, orthopaedics, otolaryngology, cardiology, critical care, and many other departments...
