Examining barriers to care: a retrospective cohort analysis investigating the relationship between hospital volume and outcomes in pediatric patients with cerebral arteriovenous malformations.

OBJECTIVE: Comprehensive data on treatment patterns of pediatric cerebral arteriovenous malformations (AVMs) are lacking. The authors' aim was to examine national trends, assess the effect of hospital volume on outcomes, and identify variables associated with treatment at high-volume centers. METHODS: Pediatric AVM admissions (for ruptured and unruptured lesions) occurring in the US in 2016 and 2019 were identified using the Kids' Inpatient Database. Demographics, treatment methods, costs, and outcomes were recorded. The effect of hospital AVM volume on outcomes and factors associated with treatment at higher-volume hospitals were analyzed. RESULTS: Among 2752 AVM admissions identified, 730 (26.5%) patients underwent craniotomy, endovascular treatment, or a combination. High-volume (vs low-volume) centers saw lower proportions of Black (8.7% vs 12.9%, p < 0.001) and lowest-income quartile (20.7% vs 27.9%, p < 0.001) patients, but were more likely to provide endovascular intervention (19.5%) than low-volume institutions (13.7%) (p = 0.001). Patients treated at high-volume hospitals had insignificantly lower numbers of complications (mean 2.66 vs 4.17, p = 0.105) but significantly lower odds of nonroutine discharge (OR 0.18 [95% CI 0.06-0.53], p = 0.009) and death (OR 0.13 [95% CI 0.02-0.75], p = 0.023). Admissions at high-volume hospitals cost more than at low-volume hospitals, regardless of whether intervention was performed ($64,811 vs $48,677, p = 0.001) or not ($64,137 vs $33,779, p < 0.001). Multivariable analysis demonstrated that Hispanic children, patients who received AVM treatment, and those in higher-income quartiles had higher odds of treatment at high-volume hospitals. CONCLUSIONS: In this largest study of US pediatric cerebral AVM admissions to date, higher hospital volume correlated with several better outcomes, particularly when patients underwent intervention. Multivariable analysis demonstrated that higher income and Hispanic race were associated with treatment at high-volume centers, where endovascular care is more common. The findings highlight the fact that ensuring access to appropriate treatment of patients of all races and socioeconomic classes must be a focus.

Experience in endoscope choice for neuroendoscopic lavage for intraventricular hemorrhage of prematurity: a systematic review.

OBJECTIVE: Intraventricular hemorrhage (IVH) of prematurity occurs in 20-38% of infants born < 28 weeks gestational age and 15% of infants born in 28-32 weeks gestational age. Treatment has evolved from conservative management and CSF diversion of temporizing and shunting procedures to include strategies aimed at primarily clearing intraventricular blood products. Neuroendoscopic lavage (NEL) aims to decrease the intraventricular blood burden under the same anesthetic as temporizing CSF diversion measures in cases of hydrocephalus from IVH of prematurity. Given the variety of neuroendoscopes, we sought to review the literature and practical considerations to help guide neuroendoscope selection when planning NEL. METHODS: We conducted a systematic review of the literature on neuroendoscopic lavage in IVH of prematurity to examine data on the choice of neuroendoscope and outcomes regarding shunt rate. We then collected manufacturer data on neuroendoscopic devices, including inflow and outflow mechanisms, working channel specifications, and tools compatible with the working channel. We paired this information with the advantages and disadvantages reported in the literature and observations from the experiences of pediatric neurosurgeons from several institutions to provide a pragmatic evaluation of international clinical experience with each neuroendoscope in NEL. RESULTS: Eight studies were identified; four neuroendoscopes have been used for NEL as reported in the literature. These include the Karl Storz Flexible Neuroendoscope, LOTTA® system, GAAB system, and Aesculap MINOP® system. The LOTTA® and MINOP® systems were similar in setup and instrument options. Positive neuroendoscope features for NEL include increased degrees of visualization, better visualization with the evolution of light and camera sources, the ability to sterilize with autoclave processes, balanced inflow and outflow mechanisms via separate channels, and a working channel. Neuroendoscope disadvantages for NEL may include special sterilization requirements, large outer diameter, and limitations in working channels. CONCLUSIONS: A neuroendoscope integrating continuous irrigation, characterized by measured inflow and outflow via separate channels and multiple associated instruments, appears to be the most commonly used technology in the literature. As neuroendoscopes evolve, maximizing clear visualization, adequate inflow, measured outflow, and large enough working channels for paired instrumentation while minimizing the footprint of the outer diameter will be most advantageous when applied for NEL in premature infants.

The impact of social determinants of health on utilization of pediatric epilepsy surgery: a systematic review.

OBJECTIVE: A minority of pediatric patients who may benefit from epilepsy surgery receive it. The reasons for this utilization gap are complex and not completely understood. Patient and caregiver social determinants of health (SDOH) may impact which patients undergo surgery and when. The authors conducted a systematic review examining SDOH and surgical intervention in children with drug-resistant epilepsy (DRE). They aimed to understand which factors influenced time to surgical program referral or receipt of epilepsy surgery among children with DRE, as well as identify areas to characterize the SDOH impacting epilepsy surgery in children and guide efforts aimed to promote health equity in epilepsy. METHODS: A systematic review was conducted using the PubMed, Embase, and Scopus databases in January 2022. Studies were analyzed by title and abstract, then full text, to identify all studies examining the impact of SDOH on utilization of epilepsy surgery. Studies meeting inclusion criteria were analyzed for SDOH examined, outcomes, and key findings. Quality was assessed using the Grading of Recommendations Assessment, Development and Evaluation system. RESULTS: Of 4545 resultant articles, 18 were included. Studies examined social, cultural, and environmental factors that contributed to SDOH impacting epilepsy surgery. Patients who underwent surgical evaluation were found to be most commonly White and privately insured and have college-educated caregivers. Five studies found differences in time to referral/surgery or rates of surgery by racial group, with most finding an increased time to referral/surgery or lower rates of surgery for those who were Hispanic and/or non-White. Four studies found that private insurance was associated with higher surgical utilization. Three studies found higher household income was related to surgical utilization. No studies examined biological, psychological, or behavioral factors that contributed to SDOH impacting epilepsy surgery. CONCLUSIONS: The authors conducted a systematic review exploring the impact of SDOH in DRE surgery utilization. They found that race, ethnicity, insurance type, caregiver educational attainment, and household income demonstrate relationships with pediatric epilepsy surgery. Further study is necessary to understand how these factors, and others not identified in this study, contribute to the low rates of utilization of epilepsy surgery and potential target areas for interventions aiming to increase equity in access to epilepsy surgery in children.

First use of intraventricular nicardipine in a pediatric patient with vasospasm secondary to meningitis: illustrative case.

BACKGROUND: Cerebral vasospasm is commonly associated with adult aneurysmal subarachnoid hemorrhage but can develop in children. The standard vasospasm treatment includes induced hypertension, avoidance of hypovolemia, systemic use of the calcium channel blocker (CCB) nimodipine, and cerebral angiography for intraarterial therapy. Emerging treatments in adults, such as intraventricular CCB administration, have not been investigated in children. This study demonstrates the successful use of an intraventricular CCB in a pediatric patient with refractory vasospasm secondary to meningitis. OBSERVATIONS: A 12-year-old female presented with Streptococcus pneumoniae meningitis and ventriculitis with refractory symptomatic cerebral vasospasm. She received a 5-day course of intrathecal nicardipine through an existing external ventricular drain. Her clinical status, transcranial Doppler studies, and radiography improved. Treatment was well tolerated. LESSONS: Pediatric vasospasm is uncommon and potentially devastating. The management of vasospasm in adults occurs frequently. Principles of this management are adapted to pediatric care given the rarity of vasospasm in children. The use of intraventricular nicardipine has been reported in the care of adults with level 3 evidence. It has not been adequately reported in children with refractory vasospasm. Here, the first use of intraventricular nicardipine in treating pediatric cerebral vasospasm in the setting of meningitis is described and highlighted.

Information Sharing in Neurosurgery Topics Among Pediatric Patients and Loved Ones Within the Reddit Community.

Introduction With crowd-sourced knowledge, patients arrive at their healthcare visits ready to play an active role. This exploratory study seeks to understand common concerns among patients and loved ones on Reddit, an anonymous internet forum. Ultimately, recognizing common concerns can aid providers in directing their conversations with patients. Methods Reddit posts in the "hot" tab of each subreddit were retroactively screened from September 1, 2022. Posts written within a five-year period were included. Posts by pediatric patients, loved ones, and pregnant patients experiencing the condition or whose fetus was diagnosed were included. Posts omitting the poster's age or individuals, outside of loved ones, who self-identified as over the age of 17 were excluded. Results A total of 12 subreddits and 286 posts were identified, with 37% of posts written by patients and 63% of posts written by a loved one. R/scoliosis patients (n=29) and r/epilepsy loved ones (n=28) sought the most health advice. The subreddit r/hydrocephalus comprised the most post-operative treatment symptom questions. The r/cerebralpalsy subreddit sought the most advice related to daily activities. Discussion Patients within r/scoliosis, r/hydrocephalus, and r/epilepsy are asking health-related questions. Hydrocephalus patients utilize anonymous internet responses to prepare for upcoming healthcare visits. Individuals in r/cerebralpalsy are utilizing Reddit as a method of communication; understanding how these patients interact with social media can guide software development tailored for online interactions. The anonymity of Reddit prevents us from understanding the diversity of posters. Conclusion Reddit is an avenue to disseminate correct information to pediatric patients and loved ones. Healthcare providers can use the information gathered to tailor their discussions better.

Visual outcomes after treatment of craniopharyngioma in children: A systematic review.

OBJECTIVE: Craniopharyngiomas (CP) are rare brain tumors that often result in visual impairment due to their proximity to the optic pathway. The optimal management approach to preserve visual function in these patients remains controversial. We sought to investigate visual outcomes of children with craniopharyngiomas based on treatment modality. METHODS: A systematic review was performed according to PRISMA guidelines. PubMed, Embase, and Scopus databases were searched in December 2022 for relevant articles. Articles were screened by title/abstract for relevance, then by full-text. Relevant demographic, intervention, and outcome data were extracted from included studies. RESULTS: A total of 59 studies were included, representing 2655 patients. The overall visual status (OVS) of patients receiving surgery alone was improved in 27.6% of reported outcomes, unchanged in 50.3%, and deteriorated in 22.1%. The OVS for patients receiving radiation alone was improved in 21.1%, unchanged in 42.1%, and deteriorated in 36.8%. Patients receiving surgery plus adjuvant radiotherapy had OVS improvement in 27.4%, unchanged in 63.2%, and deteriorated in 9.4%. Of those receiving intracystic bleomycin, 23.1% had improvement in OVS, 46.2% remained unchanged, and 30.8% deteriorated. Of patients receiving interferon-α, 34.8% improved, 54.5% remained unchanged, and 10.6% deteriorated. CONCLUSION: OVS most frequently remained unchanged regardless of intervention. The greatest improvement in OVS was seen in those receiving interferon-α or surgery alone. The greatest OVS deterioration was noted with radiation alone. Future standardized, randomized, large-scale studies with focused assessment of ophthalmologic findings are key to further understanding the impact different interventions have on visual outcomes in these children.

A Well-Being Well-Check for Neurosurgery: Evidence-Based Suggestions for Our Specialty Based on a Systematic Review.

BACKGROUND: The path through neurosurgery is rigorous. Many neurosurgeons may experience burnout, depression, or suicide throughout training and practice. We review the literature to help foster a culture of awareness and self-care and arm trainees with coping skills to reduce burnout and, thus, suicidality during all phases of their medical careers. METHODS: A systematic search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using 4 databases. 7 studies were included. RESULTS: Overlying themes of interventions were to increase balance, mindfulness, and physical fitness. The most common interventions included in programs were educational and physical activity. We suggest a comprehensive wellness program emphasizing interventions from 4 wellness dimensions-physical, spiritual, mental, and emotional. CONCLUSIONS: Many neurosurgeons experience burnout, leading to a lack of satisfaction and early retirement; this necessitates a discipline-wide acknowledgment of endemic burnout among neurosurgeons. Systemic changes are needed to refine the training process and prioritize physician well-being- this cannot be left to chance.

Unraveling the complexity of the senescence-associated secretory phenotype in adamantinomatous craniopharyngioma using multimodal machine learning analysis.

BACKGROUND: Cellular senescence can have positive and negative effects on the body, including aiding in damage repair and facilitating tumor growth. Adamantinomatous craniopharyngioma (ACP), the most common pediatric sellar/suprasellar brain tumor, poses significant treatment challenges. Recent studies suggest that senescent cells in ACP tumors may contribute to tumor growth and invasion by releasing a senesecence-associated secretory phenotype. However, a detailed analysis of these characteristics has yet to be completed. METHODS: We analyzed primary tissue samples from ACP patients using single-cell, single-nuclei, and spatial RNA sequencing. We performed various analyses, including gene expression clustering, inferred senescence cells from gene expression, and conducted cytokine signaling inference. We utilized LASSO to select essential gene expression pathways associated with senescence. Finally, we validated our findings through immunostaining. RESULTS: We observed significant diversity in gene expression and tissue structure. Key factors such as NFKB, RELA, and SP1 are essential in regulating gene expression, while senescence markers are present throughout the tissue. SPP1 is the most significant cytokine signaling network among ACP cells, while the Wnt signaling pathway predominantly occurs between epithelial and glial cells. Our research has identified links between senescence-associated features and pathways, such as PI3K/Akt/mTOR, MYC, FZD, and Hedgehog, with increased P53 expression associated with senescence in these cells. CONCLUSIONS: A complex interplay between cellular senescence, cytokine signaling, and gene expression pathways underlies ACP development. Further research is crucial to understand how these elements interact to create novel therapeutic approaches for patients with ACP.

Neurosurgery trainee well-being in a pediatric neurosurgery hospital: baseline data to motivate toward implementing change.

OBJECTIVE: The aim of this study was to obtain aggregated baseline pediatric neurosurgery well-being data at a tertiary care institution. METHODS: An institutional grant funded the completion of the Maslach Burnout Inventory (MBI) by 100% (n = 13) of the trainees during a 1-year period, including 1 pediatric neurosurgery fellow and 12 residents from 4 regional neurosurgery training programs. Aggregated and anonymized group results included frequency scores ranging from 0 (never) to 6 (every day). The mean ± SD group scores were compared to the general population of > 11,000 people in the human services professions. Burnout profiles were calculated on the basis of MBI scale scores by using established comparisons to standardized normal values. Burnout profile types include engaged, ineffective, overextended, disengaged, and burnout. RESULTS: The mean ± SD score for emotional exhaustion was 2.6 ± 1.1 for trainees compared with 2.3 ± 1.2 in the comparison population. The mean ± SD score for depersonalization was 1.6 ± 1 compared with 1.7 ± 1.2 in the comparison population. The mean ± SD score for personal accomplishment was 4.9 ± 0.7 compared with 4.3 ± 0.9 in the comparison population. Profiles were classified as engaged (n = 6), ineffective (n = 3), overextended (n = 3), and burnout (n = 1). CONCLUSIONS: Problematic profiles were present for more than half (7 [53.8%]) of pediatric neurosurgery trainees who cited higher emotional exhaustion than the general population of healthcare providers. Trainees scored lower in depersonalization and higher in personal accomplishment compared with the general population, which are both protective against burnout. Targeting factors that contribute to emotional exhaustion may have an impact on improving the overall well-being of pediatric neurosurgery trainees.

Microsurgical resection of a ruptured intraventricular arteriovenous malformation in a neonate: considerations in management. Illustrative case.

BACKGROUND: Arteriovenous malformations (AVMs) are the most common cause of intracranial hemorrhage in children, although they are rarer in neonates. Age, location, lesion architecture, and rupture status define treatment options. Sparse literature exists to guide the management of clinically symptomatic intraventricular AVM rupture in neonates. We highlight the case of a neonate with a ruptured intraventricular AVM to showcase considerations in treatment, discuss surgical technique, and help guide management. OBSERVATIONS: An 18-day-old female presented with lethargy in extremis and was found to have new intraventricular hemorrhage. Angiogram revealed a Spetzler-Martin grade 2 AVM with a right posterior choroidal feeder and deep venous drainage within the ventricle. Her age limited radiosurgical and endovascular interventions. She underwent an interhemispheric, transcollosal, intraventricular approach for complete AVM resection. Perioperative care was managed by a multidisciplinary team, successfully mitigating the patient's high risk of hemovascular collapse. LESSONS: Stereotactic radiosurgery, endovascular embolization, and microsurgery are options for AVM obliteration, and multimodal therapy must be tailored to the lesion and patient. Conservative management can also be considered. Each intervention carries risks and varying likelihoods of success. Balancing these outcomes is challenging without definitive, high-quality, evidence-based guidance. The best treatment maximizes the chance of AVM obliteration while minimizing morbidity.

Machine learning models for predicting seizure outcome after MR-guided laser interstitial thermal therapy in children.

OBJECTIVE: MR-guided laser interstitial thermal therapy (MRgLITT) is associated with lower seizure-free outcome but better safety profile compared to open surgery. However, the predictors of seizure freedom following MRgLITT remain uncertain. This study aimed to use machine learning to predict seizure-free outcome following MRgLITT and to identify important predictors of seizure freedom in children with drug-resistant epilepsy. METHODS: This multicenter study included children treated with MRgLITT for drug-resistant epilepsy at 13 epilepsy centers. The authors used clinical data, diagnostic investigations, and ablation features to predict seizure-free outcome at 1 year post-MRgLITT. Patients from 12 centers formed the training cohort, and patients in the remaining center formed the testing cohort. Five machine learning algorithms were developed on the training data by using 10-fold cross-validation, and model performance was measured on the testing cohort. The models were developed and tested on the complete feature set. Subsequently, 3 feature selection methods were used to identify important predictors. The authors then assessed performance of the parsimonious models based on these important variables. RESULTS: This study included 268 patients who underwent MRgLITT, of whom 44.4% had achieved seizure freedom at 1 year post-MRgLITT. A gradient-boosting machine algorithm using the complete feature set yielded the highest area under the curve (AUC) on the testing set (AUC 0.67 [95% CI 0.50-0.82], sensitivity 0.71 [95% CI 0.47-0.88], and specificity 0.66 [95% CI 0.50-0.81]). Logistic regression, random forest, support vector machine, and neural network yielded lower AUCs (0.58-0.63) compared to the gradient-boosting machine but the findings were not statistically significant (all p > 0.05). The 3 feature selection methods identified video-EEG concordance, lesion size, preoperative seizure frequency, and number of antiseizure medications as good prognostic features for predicting seizure freedom. The parsimonious models based on important features identified by univariate feature selection slightly improved model performance compared to the complete feature set. CONCLUSIONS: Understanding the predictors of seizure freedom after MRgLITT will assist with prognostication.

Patient family engagement and partnership: Pilot survey results in assessing behavior, communication, and quality of life in children with Lennox-Gastaut syndrome and other drug-resistant epilepsy.

OBJECTIVES: Lennox-Gastaut Syndrome (LGS) and other drug-resistant epilepsy (DRE) can impact behavior, communication, and quality of life (QoL). In collaboration with community engagement efforts with the Lennox-Gastaut Syndrome Foundation (LGSF), we aimed to gain an initial snapshot of patient and family perspectives and experiences with evaluation of behavior, communication, and QoL. METHODS: A cross-sectional survey was conducted to collect self-reported information from caregivers of children with LGS and other DRE regarding their perspectives and experiences with healthcare providers' evaluation of behavior, communication, and QoL. The survey tool was developed by the study investigators in partnership with the LGS Foundation and had diffused to caregivers online by epilepsy advocacy groups including the Pediatric Epilepsy Surgery Alliance (PESA). Responses were analyzed. Descriptive statistics were calculated. The survey asked for caregiver perspectives and assessed which instruments the caregivers had previously been given for measuring these domains. RESULTS: Responses from 245 caregivers were included, with 132 (54%) caregivers of an individual with LGS and 113 (46%) caregivers of an individual with non-LGS related DRE. Respondents reported that 66% of their loved ones had undergone epilepsy-related surgery. Over 90% agreed that measuring behavior, communication, and QoL was important, but fewer than half felt that their healthcare providers evaluated these domains well. LGS caregivers largely shared non-LGS caregivers' perspectives; however, they reported more frequently that communication was not evaluated enough. Barriers to measuring these domains included a lack of good surveys (developmentally appropriate and specific to the type of epilepsy) or not receiving any survey instruments for these domains during clinic appointments. Caregivers play a crucial role for individuals with DRE, and their input is essential in identifying challenges and needs. Caregivers believe that measuring behavior, communication, and quality of life is important, and most of them feel that their loved ones are not adequately evaluated during their healthcare encounters. There is a need for appropriately scaled survey instruments to measure areas of importance for patients and caregivers, as well as incorporation of these outcomes in the healthcare discussion.

Survival and neurological outcomes after stereotactic biopsy of diffuse intrinsic pontine glioma: a systematic review.

OBJECTIVE: Diffuse intrinsic pontine gliomas (DIPGs) are aggressive and malignant tumors of the brainstem. Stereotactic biopsy can obtain molecular and genetic information for diagnostic and potentially therapeutic purposes. However, there is no consensus on the safety of biopsy or effect on survival. The authors aimed to characterize neurological risk associated with and the effect of stereotactic biopsy on survival among patients with DIPGs. METHODS: A systematic review was performed in accordance with PRISMA guidelines to identify all studies examining pediatric patients with DIPG who underwent stereotactic biopsy. The search strategy was deployed in PubMed, Embase, and Scopus. The quality of studies was assessed using the Grading of Recommendations, Assessment, Development and Evaluation system, and risk of bias was evaluated with the Cochrane Risk of Bias in Nonrandomized Studies-of Interventions tool. Bibliographic, demographic, clinical, and outcome data were extracted from studies meeting inclusion criteria. RESULTS: Of 2634 resultant articles, 13 were included, representing 192 patients undergoing biopsy. The weighted mean age at diagnosis was 7.5 years (range 0.5-17 years). There was an overall neurosurgical complication rate of 13.02% (25/192). The most common neurosurgical complication was cranial nerve palsy (4.2%, 8/192), of which cranial nerve VII was the most common (37.5%, 3/8). The second most common complication was perioperative hemorrhage (3.6%, 7/192), followed by hemiparesis (2.1%, 4/192), speech disorders (1.6%, 3/192) such as dysarthria and dysphasia, and movement disorders (1.0%, 2/192). Hydrocephalus was less commonly reported (0.5%, 1/192), and there were no complications relating to wound infection/dehiscence (0%, 0/192) or CSF leak (0%, 0/192). No mortality was specifically attributed to biopsy. Diagnostic yield of biopsy revealed a weighted mean of 97.4% (range 91%-100%). Of the studies reporting survival data, 37.6% (32/85) of patients died within the study follow-up period (range 2 weeks-48 months). The mean overall survival in patients undergoing biopsy was 9.73 months (SD 0.68, median 10 months, range 6-13 months). CONCLUSIONS: Children with DIPGs undergoing biopsy have mild to moderate rates of neurosurgical complications and no excessive morbidity. With reasonably acceptable surgical risk and high diagnostic yield, stereotactic biopsy of DIPGs can allow for characterization of patient-specific molecular and genetic features that may influence prognosis and the development of future therapeutic strategies.

Showing Some Spine on Reddit: Neurosurgical Spinal Cord Conditions in Adults.

BACKGROUND: A crowdsourcing resource used by patients with spinal disease has yet to be thoroughly investigated: the Internet. One such platform is Reddit, a virtual, anonymous meeting place. Analyzing how patients use spinal condition "subreddits" may enable a greater understanding of the questions that patients do not ask their doctors. METHODS: Up to 50 posts in each subreddit's "hot" tab were retroactively screened from June 1, 2022. Posts written by those who had the condition or those interested in knowing more were included. Redditors self-identifying as younger than 18 years were excluded. Posts were subcategorized into questions related to social advice, health advice, providing health education or suggesting equipment, detailing their personal experience, or researchers recruiting patients for research. RESULTS: Eight subreddits with 398 posts were identified related to spinal conditions, including scoliosis, herniated disks, spondylolisthesis, kyphosis, spina bifida, and degenerative disk disease, and 2 subreddits for spinal cord injury. Most patients sought out health advice (59.8%), specifically related to questions regarding their treatments (33.6%), followed by social advice (14.1%) relating to activities in their daily lives. Six posts from the spinal cord injury subreddits discussed the inability to achieve or maintain an erection. DISCUSSION: Patients with spinal conditions congregate on Reddit. Analysis of subreddits allows for a more robust fund of knowledge, granting providers an opportunity to address the main health concerns of patients and caregivers.

Axenfeld-Rieger syndrome: A systematic review examining genetic, neurological, and neurovascular associations to inform screening.

Axenfeld-Rieger Syndrome (ARS) is comprised of a group of autosomal dominant disorders that are each characterized by anterior segment abnormalities of the eye. Mutations in the transcription factors FOXC1 or PITX2 are the most well-studied genetic manifestations of this syndrome. Due to the rarity this syndrome, ARS-associated neurological manifestations have not been well characterized. The purpose of this systematic review is to characterize and describe ARS neurologic manifestations that affect the cerebral vasculature and their early and late sequelae. PRISMA guidelines were followed; studies meeting inclusion criteria were analyzed for study design, evidence level, number of patients, patient age, whether the patients were related, genotype, ocular findings, and nervous system findings, specifically neurostructural and neurovascular manifestations. 63 studies met inclusion criteria, 60 (95%) were case studies or case series. The FOXC1 gene was most commonly found, followed by COL4A1, then PITX2. The most commonly described structural neurological findings were white matter abnormalities in 26 (41.3%) of studies, followed by Dandy-Walker Complex 12 (19%), and agenesis of the corpus callosum 11 (17%). Neurovascular findings were examined in 6 (9%) of studies, identifying stroke, cerebral small vessel disease (CSVD), tortuosity/dolichoectasia of arteries, among others, with no mention of moyamoya. This is the first systematic review investigating the genetic, neurological, and neurovascular associations with ARS. Structural neurological manifestations were common, yet often benign, perhaps limiting the utility of MRI screening. Neurovascular abnormalities, specifically stroke and CSVD, were identified in this population. Stroke risk was present in the presence and absence of cardiac comorbidities. These findings suggest a relationship between ARS and neurovascular findings; however, larger scale studies are necessary inform therapeutic decisions.

Gaps in transitional care to adulthood for patients with cerebral palsy: a systematic review.

PURPOSE: The transition from pediatric to adult care can be complex and difficult to navigate for adolescents with cerebral palsy (CP). We aimed to assess the current state of transitional care for young persons with CP and delineate guidelines for best practice with opportunities for intervention. METHODS: A systematic review was conducted using PRISMA guidelines to search PubMed, Embase, and Scopus databases. Articles were screened for relevance via title and abstract prior to full-text review. RESULTS: Of 3151 resultant articles, 27 observational studies were included. Fourteen (52%) studies assessed clinical outcomes of patients with CP during and post-transition. Transition-associated poor outcomes included housing instability, unemployment, difficulty forming relationships, increased hospital admission rates, and decreased use of rehabilitation services. Factors associated with improved outcomes included family participation, promotion of self-efficacy, and meeting the adult team before transition. Nine (33%) studies conducted interviews with transition-age persons with CP. Key themes were a lack of transition preparedness, difficulty navigating the adult system, gaps in seamless care, and limited accessibility to specialists and environments suitable for patients with complex care needs. Four (15%) studies examined features of current transition services. Perceived barriers included poor communication within health service teams, limited adult providers accepting CP patients, and the lack of financial resources for specialized care. There was no standardized transition tool or approach. CONCLUSION: These findings underscore the importance of a planned transition process in optimizing long-term medical and psychosocial outcomes for persons with CP. Further research, including translational, team-based, and community-engaged research, are needed.

Rett Syndrome-Associated Scoliosis: Analysis of National Trends and Treatment Patterns of a Rare Indication for Posterior Instrumented Fusion.

STUDY DESIGN: Retrospective database cohort study. OBJECTIVE: To evaluate U.S. treatment trends and inpatient outcomes for children undergoing posterior spinal fusion (PSF) for Rett syndrome (RTT)-associated scoliosis (RAS). SUMMARY OF BACKGROUND DATA: RTT is a rare, sporadic neurodevelopmental disorder presenting in childhood with developmental regression, ataxia, and seizures. RAS occurs in 50% to 80% of cases of RTT, but little is known about the case volume and perioperative experience for children undergoing PSF. MATERIALS AND METHODS: Using the International Classification of Diseases Ninth and 10th revision codes in the national Kids' Inpatient Database, we identified children with RTT who underwent PSF from 2000 to 2019. Annual case volumes were analyzed. Clinical characteristics and outcomes were compared with those of a cohort of patients with neuromuscular scoliosis (NMS). RESULTS: Among 220 patients with RAS, 216 (98.2%) were females (mean age at surgery: 12.3±3.3 yr). Surgical case incidence steadily increased over 19 years, with more RAS admissions in the South (31.4%). Overall, patients with RAS demonstrated a higher mean Elixhauser Comorbidity Index score (2 vs . 1, P < 0.001) and had more perioperative complications (41.4% vs . 18%, P < 0.001) than patients with NMS. RTT diagnosis independently predicted higher odds of any complications (odds ratio: 1.98, P < 0.001) and increased length of stay (odds ratio: 1.18, P = 0.009) for admissions for PSF. CONCLUSIONS: Surgical treatment for RAS is rare but increased over a 19-year period. Cases appear to be clustering by region, with the highest proportion in the South. The higher Elixhauser Comorbidity Index in RAS patients predicted higher costs, longer hospital stays, more complications (particularly respiratory), and more nonroutine discharge disposition than in other patients with NMS. RTT was independently associated with higher odds of complications and longer length of stay. Because RAS cases appear to be increasing in number, future studies should emphasize methods to reduce morbidity and investigate deformity-specific metrics to help better understand this population.

Your Brain on Reddit: Exploring Neurosurgical Concerns on a Popular Social Media Site.

OBJECTIVE: Social media has irreversibly impacted global interpersonal connectivity. This study aims to understand how information discussed in condition-specific communities, called "subreddits," on the major social media platform Reddit, can improve education by medical providers. METHODS: The top 50 Reddit posts in each subreddit's "hot" tab were retroactively screened from June 1, 2022. Posts written by those 18 and older who had the condition or were engaging in a better understanding of the condition were included in the analysis. In addition, posts were placed in 1 of 6 categories based on the redditors' primary questions: social advice, health advice, providing health education or suggesting equipment, personal experience/progress, researchers recruiting patients for research, or others. RESULTS: We identified 605 posts within 15 subreddits related to cranial neurosurgical topics including epilepsy, traumatic brain injury, stroke, brain tumors/cancer, seizures, hydrocephalus, cerebrospinal fluid leaks, Chiari malformations, aneurysms, pineal cysts, ataxia, and moyamoya. Asking for health advice was the most common form of information seeking across subreddits (53.6%), specifically treatment-related questions (41.0%). Redditors from r/epilepsy and r/seizures constituted 84.6% of nonsurgical treatment questions relating to antiepileptic dosing or side effects. CONCLUSIONS: Cranial neurosurgical disease can overwhelm patients, leaving them with unaddressed questions. Reddit provides anonymity and camaraderie within condition-specific communities not found at the doctor's office. The ease of access to an Internet community may encourage redditors to seek health information online.
