Assessing frailty screening tools for predicting morbidity for suboccipital decompression in adults with Chiari malformation type I.

Objective: The revised Risk Analysis Index (RAI-rev) and modified 5-item frailty index (mFI-5) are comprehensive assessment tools of frailty that have been used to predict neurosurgical outcomes. The aim of this study was to investigate the utility of these tools to predict extended hospital length of stay (LOS), nonroutine discharge (NRD), and 30-day adverse events (AEs) among patients with Chiari malformation type I (CM-I) undergoing suboccipital decompression.

Methods: The authors conducted a retrospective cohort study using the 2011-2022 American College of Surgeons National Surgical Quality Improvement Program database to identify adults with CM-I who underwent suboccipital decompression.

Lumbocaval Shunt for Idiopathic Intracranial Hypertension: A Technical Report and Case Series.

Background And Objectives: Neurosurgical management of idiopathic intracranial hypertension (IIH) can be challenging given high rates of revision associated with cerebrospinal fluid shunting. In this study, we present a technical report and early outcomes for lumbocaval shunt (LCS) placement in difficult-to-manage cases.

Methods: A literature search was performed for previous reports of LCS or lumboatrial shunt.

Unnecessary Scans Lead to Unnecessary Re-scans: Evaluating Clinical Management of Low and Intermediate Risk Pediatric Traumatic Brain Injuries.

Background: The Pediatric Emergency Care Applied Research Network (PECARN) guidelines provide an algorithm to select patients with mild head trauma at highest risk for clinically important traumatic brain injury (ciTBI) in whom computed tomography (CT) would facilitate management. Failure to follow PECARN criteria exposes children to unnecessary radiation and contributes to increasing hospital costs, length of stay, and parental anxiety. We sought to evaluate the subsequent allocation of resources to low and intermediate risk group patients who underwent an initial Head CT - which was not indicated by PECARN guidelines but which identified cranial or intracranial injury.

Impact of preoperative nutritional status on morbidity and mortality in elderly patients undergoing subdural hematoma evacuation: the role of the Geriatric Nutritional Risk Index.

Objective: Nutritional status has been shown to impact patient outcomes across several neurosurgical procedures. However, few prior studies have assessed associations between preoperative nutritional status and outcomes in elderly patients undergoing subdural hematoma evacuations. The aim of this study was to identify associations between preoperative nutritional status and short-term outcomes in patients aged 65 years and older undergoing subdural hematoma evacuation.

Isolated unilateral alar ligamentous injury: illustrative cases.

Background: Isolated unilateral alar ligament injury (IUALI) is a rare and likely underreported occurrence after upper cervical trauma, with only 16 cases documented in the literature to date. Patients generally present with neck pain, and definitive diagnosis is typically made by magnetic resonance imaging (MRI). Unfortunately, likely due in part to its rarity, there are no formal guidelines for the treatment of an IUALI.

Reduced racial disparities among newborns with intraventricular hemorrhage.

Introduction: Intraventricular hemorrhage (IVH) can ensue permanent neurologic dysfunction, morbidity, and mortality. While previous reports have identified disparities based on patient gender or weight, no prior study has assessed how race may influence in neonatal or infantile IVH patients. The aim of this study was to investigate the impact of race on adverse event (AE) rates, length of stay (LOS), and total cost of admission among newborns with IVH.

Impact of a quality improvement initiative and monthly multidisciplinary meetings on outcomes after posterior spinal fusion for adolescent idiopathic scoliosis.

Introduction: Several studies have demonstrated the benefits of enhanced recovery after surgery (ERAS) protocols for patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal instrumented fusion (PSIF). However, there are relatively few studies investigating the effect of regular multidisciplinary team meetings on level selection, surgical performance parameters, and patient outcomes after PSIF for AIS. The aim of this study was to assess changes in intra- and postoperative outcomes following multidisciplinary team meeting implementation for patients undergoing PSIF for AIS.

Influence of affective disorders on outcomes after suboccipital decompression for adult Chiari I malformation.

Introduction: Affective disorders (AD) have been shown to influence patient outcomes and healthcare resource utilization across several pathologies, though this relationship has not been described in patients with Chiari I malformations (CM-I). The aim of this study was to determine the impact of comorbid AD on postoperative events and healthcare resource utilization in adults following suboccipital decompression for CM-I.

Methods: A retrospective study was performed using the 2016-2019 National Inpatient Sample database.

Virtual Surgical Planning in Craniosynostosis Reduces Operative Time and Length of Stay for Cranial Vault Remodeling.

Cranial vault remodeling (CVR) with and without frontal orbital advancement remodels the skull in craniosynostosis. Virtual surgical planning (VSP) for preoperative planning has been previously shown to be effective in CVR. In this study, the authors aimed to evaluate the impact of VSP on operative and perioperative efficiency for craniosynostosis surgery.

Personality Changes and Staring Spells in a 12-Year-Old Child: A Case Report Incorporating ChatGPT, a Natural Language Processing Tool Driven by Artificial Intelligence (AI).

Low grade gliomas (LGGs) are the most common type of brain tumors diagnosed in children. The presentation of intracranial tumors in pediatric patients is varied and diverse. The early identification and treatment of LGGs are important to achieve favorable outcomes.

Association Between Intravenous to Oral Opioid Transition Time and Length of Hospital Stay After Posterior Spinal Fusion for Adolescent Idiopathic Scoliosis.

Background: Transitioning from intravenous (IV) to oral opioids after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) is necessary during the postoperative course. However, few studies have assessed the effects of longer transition times on hospital length of stay (LOS). This study investigated the impact of longer IV to oral opioid transition times on LOS after PSF for AIS.

Impact of insurance status on healthcare resource utilization and outcomes in adolescent patients presenting with spinal cord injuries.

Objective: Insurance disparities have been suggested to influence the medical and surgical outcomes of adult patients with spinal cord injury (SCI), with a paucity of studies demonstrating their impact on the outcomes of pediatric and adolescent SCI patients. The aim of this study was to assess the impact of insurance status on healthcare utilization and outcomes in adolescent patients presenting with SCI.

Methods: An administrative database study was performed using the 2017 admission year from 753 facilities using the National Trauma Data Bank.

Use of droxidopa for blood pressure augmentation after acute spinal cord injury: case reports.

Hypotension secondary to autonomic dysfunction is a common complication of acute spinal cord injury (SCI) that may worsen neurologic outcomes. Midodrine, an enteral α-1 agonist, is often used to facilitate weaning intravenous (IV) vasopressors, but its use can be limited by reflex bradycardia. Alternative enteral agents to facilitate this wean in the acute post-SCI setting have not been described.

Management of dynamic cervical kyphosis with dorsal epidural lipomatosis: a Hirayama disease variant? Illustrative case.

Background: Hirayama disease, a cervical myelopathy characterized most commonly by a self-limiting atrophic weakness of the upper extremities, is a rare entity, scarcely reported in the literature. Diagnosis is made by spinal magnetic resonance imaging (MRI), which typically shows loss of normal cervical lordosis, anterior displacement of the cord during flexion, and a large epidural cervical fat pad. Treatment options include observation or cervical immobilization by collar or surgical decompression and fusion.

Multiomic analyses implicate a neurodevelopmental program in the pathogenesis of cerebral arachnoid cysts.

Cerebral arachnoid cysts (ACs) are one of the most common and poorly understood types of developmental brain lesion. To begin to elucidate AC pathogenesis, we performed an integrated analysis of 617 patient-parent (trio) exomes, 152,898 human brain and mouse meningeal single-cell RNA sequencing transcriptomes and natural language processing data of patient medical records. We found that damaging de novo variants (DNVs) were highly enriched in patients with ACs compared with healthy individuals (P = 1.

The choroid plexus links innate immunity to CSF dysregulation in hydrocephalus.

The choroid plexus (ChP) is the blood-cerebrospinal fluid (CSF) barrier and the primary source of CSF. Acquired hydrocephalus, caused by brain infection or hemorrhage, lacks drug treatments due to obscure pathobiology. Our integrated, multi-omic investigation of post-infectious hydrocephalus (PIH) and post-hemorrhagic hydrocephalus (PHH) models revealed that lipopolysaccharide and blood breakdown products trigger highly similar TLR4-dependent immune responses at the ChP-CSF interface.

Biallelic inactivation of PBRM1 as a molecular driver in a rare pineoblastoma case: illustrative case.

Background: Pineoblastomas are a rare and aggressive pediatric neuroectodermal tumor subtype. Because of their rarity, pineoblastomas are still poorly understood, and there is little research delineating their molecular development and underlying genetic phenotype. Recent multiomic studies in pineoblastomas and pineal parenchymal tumors identified four clinically and biologically relevant consensus groups driven by signaling/processing pathways; however, molecular level alterations leading to these pathway changes are yet to be discovered, hence the importance of individually profiling every case of this rare tumor type.
