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.

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.

Navigating the transition: the crucial shift from pediatric to adult care for individuals living with spina bifida.

OBJECTIVE: Spina bifida (SB) is a complex congenital condition characterized by incomplete closure of the neural tube, resulting in varying degrees of physical and neurological impairment. Although commonly managed by multidisciplinary pediatric clinics, a substantial proportion of SB patients are now living into adulthood, necessitating the transition from pediatric to adult healthcare. This transition introduces a myriad of challenges for individuals living with SB and their families. Prior research on SB transition programs has demonstrated anecdotal success; however, minimal research has been published on early posttransition health outcomes and compliance with medical recommendations. This quality improvement study assessed early posttransition compliance with medical recommendations, adverse health events, access to medical supplies/equipment, and patient-reported health outcome and confidence in medical providers. METHODS: Adult participants in the Spina Bifida Transition Clinic at the authors' pediatric institution were invited to complete a telephone survey after transition to adult care. The mean (SEM) elapsed time since transition was 1.21 (0.11) years. The survey evaluated adult provider utilization, accessibility of medical supplies and equipment, adverse medical events, compliance with sleep study acquisition, patient-reported health status, and satisfaction with providers. RESULTS: Of 52 eligible participants, 49 (94%) completed a telephone survey. Within the cohort, 82% had open SB (myelomeningocele), with the remaining having occult SB (lipomyelomeningocele). The mean age at transition was 26.0 years. Since transition, 78% have attended at least one primary care visit, with 76% seeking care from at least one adult care specialist (69% sought care with urologists). Forty-five percent reported an adverse medical event: 31% required an emergency department visit, 22% were hospitalized, 18% underwent surgery, and 24% had skin breakdown. Access to medical supplies varied, with patients experiencing the most difficulty obtaining wheelchairs and assistive walking devices. Patients rated pediatric provider engagement and knowledge of SB significantly higher than adult providers (mean 3.92 vs 3.32, p < 0.001). CONCLUSIONS: This quality improvement study evaluated the effectiveness of our Spina Bifida Transition Clinic in the early post transition period. While patients have used primary and specialty care (urology), they have experienced many adverse events and low compliance with sleep study acquisition. Continued evaluation of transition programs is required to optimize the outcome of those living with SB.

Barriers to healthcare transition for spina bifida patients: a systematic review.

OBJECTIVE: Patients with spina bifida (SB) were historically followed by pediatric providers throughout their entire lives. Through medical and surgical advancements, now more pediatric SB patients are living well into adulthood. Nonetheless, many patients fail to successfully transition to appropriate adult healthcare providers. The goal of this study was to identify factors that helped facilitate or hinder the successful transition of adolescent and young adult (AYA) SB patients to adult providers. METHODS: A systematic review was conducted exploring the transition care of SB patients using the PubMed, Embase, and Scopus databases. Titles and abstracts from articles identified were read and selected for full-text review. Studies meeting the inclusion criteria were reviewed in full and analyzed for study design, populations, interventions, and factors influencing transition. RESULTS: The primary search identified 2050 articles, of which 20 were included in the final review. Thirteen studies discussed factors relating to neurosurgical care, 8 referenced gastrointestinal and genitourinary considerations, 11 examined cognitive and psychosocial factors, and 17 explored healthcare system factors. Several barriers were consistently reported regarding communication, patient and parental attitudes and perceptions, and failure to embrace formalized and transparent protocols. Conflicting results were reported regarding the influence medical comorbidities had on a patient's ability to transition. CONCLUSIONS: The process of transitioning AYA SB patients to adult care is complex, involving an interplay of structural and psychosocial factors. The findings in this review suggest that some barriers can be alleviated with improved education, planning, and awareness of factors that influence transition care.

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.

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.

Neurosurgery Residency Programs on Twitter (X): Current Use and Future Potential.

OBJECTIVE: Twitter (X) is increasingly utilized by medical residency programs to boost engagement and potentially enhance ranking. This study aims to evaluate the role of Twitter (X) in neurosurgery residency programs, assessing their online activity, followership, and content to identify current practices and potential improvements. METHODS: We identified 97/123 neurosurgery residency programs in the United States with Twitter accounts. Active accounts, posting in 2022 and 2023, were matched with the American Association of Neurological Surgeons Neurosurgical Residency Training Program Directory. Tweets from January 2022 through June 2023 were categorized as original or retweets and further subcategorized based on content. Descriptive and correlation analyses were conducted. RESULTS: Twitter (X) accounts were found for 78.8% of accredited neurosurgery programs (n = 97/123), with 68.3% active as of July 2023 (n = 84/123). All active accounts amassed 167,068 followers. Among 5612 tweets identified, 2764 were original content, and 2848 were retweets. Tweets primarily focused on resident or program information (64.3%), research publications (32.0%), and conference participation (9.4%). Only 12.3% (n = 341) of original tweets contained public medical information. A significant correlation (r = 0.493, P < 0.001) was observed between Twitter (X) following and program ranking. CONCLUSIONS: The majority of US neurosurgery residency programs actively use Twitter (X), primarily to showcase academic achievements and aid in recruitment. The correlation between Twitter following and program ranking suggests that online engagement reflects program visibility and impact, underscoring the importance of social media in program outreach and strategic management for maximizing program benefits.

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.

Re-examining the classification of abdominal pseudocysts as surgical site infections through review of broad-range polymerase chain reaction results.

BACKGROUND: The Hydrocephalus Clinical Research Network-quality group (HCRNq) historically defined all abdominal pseudocysts associated with a ventriculoperitoneal shunt as a surgical site infection regardless of culture result. METHODS: We retrospectively reviewed broad-range polymerase chain reaction (BRPCR) results sent between January 2017 and July 2023 from abdominal pseudocyst fluid sent from hospitals around the country to a reference laboratory to help further characterize these collections. RESULTS: A total of 19 samples were tested via BRPCR between 1/2017 and 7/2023. Two (10.5 %) had organisms identified; one with Staphylococcus epidermidis and one with Candida parapsilosis. No fastidious organisms that would be expected to not grow with typical culture techniques were identified. CONCLUSIONS: Few abdominal pseudocysts had organisms identified by BRPCR, suggesting that not all pseudocysts are due to infectious causes. Consideration should be given to alternate causes of pseudocyst development when cultures are negative.

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.

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.

Pediatric glioma immune profiling identifies TIM3 as a therapeutic target in BRAF-Fusion pilocytic astrocytoma.

Despite being the leading cause of childhood mortality, pediatric gliomas have been relatively understudied, and the repurposing of immunotherapies has not been successful. Whole transcriptome sequencing, single-cell sequencing, and sequential multiplex immunofluorescence were used to identify an immunotherapy strategy evaluated in multiple preclinical glioma models. MAPK-driven pediatric gliomas have a higher interferon signature relative to other molecular subgroups. Single-cell sequencing identified an activated and cytotoxic microglia population designated MG-Act in BRAF-fused MAPK-activated pilocytic astrocytoma (PA), but not in high-grade gliomas or normal brain. TIM3 is expressed on MG-Act and on the myeloid cells lining the tumor vasculature but not normal brain. TIM3 expression becomes upregulated on immune cells in the PA microenvironment and anti-TIM3 reprograms ex vivo immune cells from human PAs to a pro-inflammatory cytotoxic phenotype. In a genetically engineered murine model of MAPK-driven low-grade gliomas, anti-TIM3 treatment increased median survival over IgG and anti-PD1 treated mice. ScRNA sequencing data during the therapeutic window of anti-TIM3 demonstrates enrichment of the MG-Act population. The therapeutic activity of anti-TIM3 is abrogated in the CX3CR1 microglia knockout background. These data support the use of anti-TIM3 in clinical trials of pediatric low-grade MAPK-driven gliomas.
