OBJECTIVE: The transition from pediatric to adult care is challenging for patients and families with spina bifida (SB). Lifelong care relationships yield to new care environments that are typically larger, less personal, and less engaged with the nuances of SB care. Adolescence and young adulthood are often characterized by personal and psychological stresses due to factors independent of illness or chronic medical complexity. Surveys have demonstrated that transition is associated with uncertainty, anxiety, and elevated risk of adverse events for many SB patients. To help mitigate this, the authors developed a trial mentorship program between teen patients with SB and undergraduate/medical students. This study analyzes and presents the initial outcomes from this program. METHODS: The authors created the Join, Unite, Motivate, and Prepare (JUMP) program to improve readiness for the transition process. The mentee target population was patients aged 13-19 years receiving care at the authors' SB clinic. Mentors were screened/approved undergraduate/medical students who volunteered to participate and successfully completed online training in mentorship. Upon enrollment, each patient set a combination of clinical, self, and parent/guardian goals using the individualized transition plan. These goals were shared with the mentor, mentee, parent/guardian, and physician. To monitor success, the SB program director routinely met with each mentor to discuss progress made and areas of growth. These included continuous quantitative and qualitative goal setting and failures that needed to be addressed for each agenda. RESULTS: Thirteen mentor-mentee matches were created over 9 months. Of the 13 matches, 6 had more than 5 communications after the initial meeting, and 1 mentor-mentee match is still in contact today. Noted success in the program has been through mentees gaining employment, applying for scholarships, starting college, and connecting with others who are going through similar circumstances. Challenges have arisen through failure to follow-up after the initial office visit, risk with using the virtual platform, and wide geographic dispersion of both mentors and mentees across the authors' state. CONCLUSIONS: Transition from pediatric to adult care for adolescents with SB has proven to be a large hurdle. Easing this process through well-thought-out, interactive processes has the potential to improve readiness, increase patient autonomy, and provide exposure to the adult healthcare community. However, the mentorship model, in the SB setting, has not proven to be the remedy.

OBJECTIVE: Interdisciplinary care and pediatric to adult transitional programs have consistently shown medical and social value for individuals with complex medical conditions such as spina bifida (SB). Such interdisciplinary clinics are common in pediatrics but are rarely offered for adults. This survey-based study reports information related to transition, daily pain burden, and satisfaction with care delivery in an adult SB clinic. METHODS: A 23-question survey that was based on empirical observations from the adult SB clinic was formulated, IRB approved, and distributed to adult patients. Many respondents had previously received care at the institution's pediatric SB clinic and completed transition to the adult program. Responses were de-identified, categorized, stored in a secure database, and statistically analyzed using SPSS. RESULTS: Of 245 patients approached, 116 (47%) surveys were completed and analyzed. Those who had a direct transition (defined as a less than 24-month gap in care) from the pediatric to the adult clinic comprised 44% (n = 51) of responders. The alternative group of 56% (n = 65) had a longer gap, disorganized or absent transition, or had pediatric care elsewhere. The study population had an average age of 36 years, had mostly received childhood care at the authors' institution, regardless of whether they made a direct transition or had a gap in care (68%), and held the diagnosis of open myelomeningocele (78%). Overall satisfaction with the clinic experience was high (mean score 9.04 on a 10-point subjective scale). Differences regarding independence in activities of daily living based on transition status were not significant, but on multivariate analysis, those who reported independence in activities of daily living had an almost 4-fold higher odds of daily pain (p = 0.024; OR 3.86, 95% CI 1.19-12.5). The most frequently identified areas for improvement included improved access to care and pain control. CONCLUSIONS: Pediatric transitional processes and interdisciplinary clinics may contribute to improved patient-perceived outcomes and satisfaction with their SB care in comprehensive settings. Further elucidation of barriers to pain control is warranted, in addition to ways in which comprehensive and longitudinal care can improve them.

INTRODUCTION: Myelomeningocele (MMC) is the most common neural tube defect, but rarely seen in premature infants. Most centers advocate for closure of MMC within 24 h of birth. However, this is not always possible in severely premature infants. Given the rarity of this patient population, we aimed to share our institutional experience and outcomes of severely premature infants with MMC. METHODS: We performed a retrospective, observational review of premature infants (≤ 32 weeks gestational age) identified through our multidisciplinary spina bifida clinic (1995-2021) and surgical logs. Descriptive statistics were compiled about this sample including timing of MMC closure and incidence of adverse events such as sepsis, CSF diversion, meningitis, and death. RESULTS: Eight patients were identified (50% male) with MMC who were born ≤ 32 weeks gestational age. Mean gestational age of the population was 27.3 weeks (SD 3.5). Median time to MMC closure was 1.5 days (IQR = 1-80.8). Five patients were taken for surgery within the recommended 48 h of birth; 2 patients underwent significantly delayed closure (107 and 139 days); and one patient's defect epithelized without surgical intervention. Six of eight patients required permanent cerebrospinal fluid (CSF) diversion (2 patients were treated with ventriculoperitoneal shunting (VPS), three were treated with endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) and 1 patient treated with ETV; mean of 3 years after birth, ranging from 1 day to 16 years). Two patients required more than one permanent CSF diversion procedure. Two patients developed sepsis (defined as meeting at least 2/4 SIRS criteria). In both cases of sepsis, patients developed signs and symptoms more than 72 h after birth. Notably, both instances of sepsis occurred unrelated to operative intervention as they occurred before permanent MMC closure. Two patients had intraventricular hemorrhage (both grade III). No patients developed meningitis (defined as positive CSF cultures) prior to MMC closure. Median follow up duration was 9.7 years. During this time epoch, 3 patients died: Two before 2 years of age of causes unrelated to surgical intervention. One of the two patients with grade III IVH died within 24 h of MMC closure. CONCLUSIONS: In our institutional experience with premature infants with MMC, some patients underwent delayed MMC closure. The overall rate of meningitis, sepsis, and mortality for preterm children with MMC was similar to MMC patients born at term.
RESUMEN
BACKGROUND AND OBJECTIVES: Vein of Galen malformation (VOGM), the result of arteriovenous shunting between choroidal and/or subependymal arteries and the embryologic prosencephalic vein, is among the most severe cerebrovascular disorders of childhood. We hypothesized that in situ analysis of the VOGM lesion using endoluminal tissue sampling (ETS) is feasible and may advance our understanding of VOGM genetics, pathogenesis, and maintenance. METHODS: We collected germline DNA (cheek swab) from patients and their families for genetic analysis. In situ VOGM "endothelial" cells (ECs), defined as CD31+ and CD45-, were obtained from coils through ETS during routine endovascular treatment. Autologous peripheral femoral ECs were also collected from the access sheath. Single-cell RNA sequencing of both VOGM and peripheral ECs was performed to demonstrate feasibility to define the transcriptional architecture. Comparison was also made with a published normative cerebrovascular transcriptome atlas. A subset of VOGM ECs was reserved for future DNA sequencing to assess for somatic and second-hit mutations. RESULTS: Our cohort contains 6 patients who underwent 10 ETS procedures from arterial and/or venous access during routine VOGM treatment (aged 12 days to â¼6 years). No periprocedural complications attributable to ETS occurred. Six unique coil types were used. ETS captured 98 ± 88 (mean ± SD; range 17-256) experimental ECs (CD31+ and CD45-). There was no discernible correlation between cell yield and coil type or route of access. Single-cell RNA sequencing demonstrated hierarchical clustering and unique cell populations within the VOGM EC compartment compared with peripheral EC controls when annotated using a publicly available cerebrovascular cell atlas. CONCLUSION: ETS may supplement investigations aimed at development of a molecular-genetic taxonomic classification scheme for VOGM. Moreover, results may eventually inform the selection of personalized pharmacologic or genetic therapies for VOGM and cerebrovascular disorders more broadly.

RESUMEN
Endoscopic third ventriculostomy (ETV) is a well-established surgical technique for treating hydrocephalus. Many providers have transitioned to utilizing the specialized Neuroballoon for the stoma dilation in ETV; however, these devices are intermittently unavailable during supply chain shortages. We present the experience of employing cardiac angioplasty and neurovascular balloons as substitutes for the Neuroballoon in 3 patients. The scepter balloon (Microvention), priced at $1800 compared to the standard $300 Neuroballoon (Integra), proved effective, but its pliability presented technical challenges. The substantial cost differential compared to a Neuroballoon ($300) raises economic considerations. The Cardiac TREK balloon (Abbott) was similarly effective, while also being easier to manage endoscopically and cheaper at $158. These experiences support the viability of non-neuroendoscopic specialized balloons as alternatives for ETV dilation of the floor of tuber cinereum.

Hydrocephalus (HC) is a heterogenous disease characterized by alterations in cerebrospinal fluid (CSF) dynamics that may cause increased intracranial pressure. HC is a component of a wide array of genetic syndromes as well as a secondary consequence of brain injury (intraventricular hemorrhage (IVH), infection, etc.) that can present across the age spectrum, highlighting the phenotypic heterogeneity of the disease. Surgical treatments include ventricular shunting and endoscopic third ventriculostomy with or without choroid plexus cauterization, both of which are prone to failure, and no effective pharmacologic treatments for HC have been developed. Thus, there is an urgent need to understand the genetic architecture and molecular pathogenesis of HC. Without this knowledge, the development of preventive, diagnostic, and therapeutic measures is impeded. However, the genetics of HC is extraordinarily complex, based on studies of varying size, scope, and rigor. This review serves to provide a comprehensive overview of genes, pathways, mechanisms, and global impact of genetics contributing to all etiologies of HC in humans.

INTRODUCTION: Pediatric non-galenic pial arteriovenous fistulas (pAVFs) are rare vascular malformations that are characterized by a pial arterial-venous connection without an intervening capillary bed. Outcomes and treatment strategies for pAVFs are highly individualized, owing to the rarity of the disease and lack of large-scale data guiding optimal treatment approaches. METHODS: We performed a systematic review of pediatric patients (< 18 years at diagnosis) diagnosed with a pAVF by digital subtraction angiogram (DSA). The demographics, treatment modalities, and outcomes were documented for each patient and clinical outcome data was collected. Descriptive information stratified by outcome scores were classified as follows: 1 = excellent (no deficit and full premorbid activity), 2 = good (mild deficit and full premorbid activity), 3 = fair (moderate deficit and impaired activity), 4 = poor (severe deficit and dependent on others), 5 = death. RESULTS: A total of 87 studies involving 231 patients were identified. Median age at diagnosis was 3 years (neonates to 18 years). There was slight male preponderance (55.4%), and 150 subjects (81.1%*) experienced excellent outcomes after treatment. Of the 189 patients treated using endovascular approaches, 80.3% experienced excellent outcomes and of the 15 patients surgically treated subjects 75% had an excellent outcome. The highest rate of excellent outcomes was achieved in patients treated with Onyx (95.2%) and other forms of EvOH (100%). High output heart failure and comorbid vascular lesions tended to result in worse outcomes, with only 54.2% and 68% of subjects experiencing an excellent outcome, respectively. *Outcomes were reported in only 185 patients. CONCLUSION: pAVFs are rare lesions, necessitating aggregation of patient data to inform natural history and optimal treatment strategies. This review summarizes the current literature on pAVF in children, where children presenting with heart failure as a result of high flow through the lesion were less likely to experience an excellent outcome. Prospective, large-scale studies would further characterize pediatric pAVFs and enable quantitative analysis of outcomes to inform best treatment practices.

Since 2018, a neurosurgery delegation has been actively engaged and consistently present at the World Health Assembly. Recognizing the growing impact of neurosurgical diseases, the neurosurgery delegation participated in the 76th World Health Assembly in May 2023, advocating for timely, safe, and affordable global neurosurgical care. The delegation focused on forging new collaborations, strengthening the World Health Organization-World Federation of Neurosurgical Societies official relations, and actively supporting resolutions that impact the neurosurgical patients. However, there is a long advocacy journey ahead to address unmet neurosurgical needs. Patient-centered advocacy is an inherent task of our profession and the essence of the Global Neurosurgery Bogota Declaration of 2016. The highlight of the 76th World Health Assembly was the adoption of the first neurosurgery-driven resolution calling for micronutrient fortification to prevent spina bifida and other micronutrient deficiencies. For the last 4 years, the Global Alliance for Prevention of Spina Bifida, a group spearheaded by neurosurgeons, advocated for spina bifida prevention. This Alliance collaborated with many stakeholders, notably, the Colombian government to promote the resolution: "Accelerating efforts for preventing micronutrient deficiencies and their consequences, including spina bifida and other neural tube defects, through safe and effective food fortification." This is a proud milestone for the neurosurgical profession. There are many strategies available for neurosurgeons, when working together with elected leaders, other stakeholders, and allied professionals, to implement initiatives that can prevent future cases of spina bifida and other neurological disorders and reduce the burden of neurosurgical disease.

BACKGROUND: Dural arteriovenous fistulas (dAVF) are arteriovenous shunts in communication with the dural vasculature in the brain or spine. Apart from single-center series, risk factors and treatment outcomes for pediatric dAVFs are largely undescribed. METHODS: We performed a systematic literature review of pediatric (< 18 years at diagnosis) intracranial and spinal dAVF according to PRISMA guidelines. We queried PubMed, CINAHL, SCOPUS, and Embase databases without time/date restriction. Search strings included a variety of MeSH keywords relating to dural AV fistulas in combination with MeSH keywords related to pediatric cases (see Appendix). Manuscripts describing patients diagnosed with dural sinus malformations or pial AVF were excluded. RESULTS: We identified 61 studies describing 69 individual patients. Overall, dAVF were more common in males (55.1%) with a mean age of diagnosis (5.17 ± 4.42 years). Approximately 20.2% of patients presented with cardiovascular disease (CVD), and 31.9% were discovered incidentally on neuroimaging studies. Transverse-sigmoid junction was the most common location (17.3%). Ninety-three percent (64 patients) were treated, most commonly using endovascular embolization (68.1%) followed by surgery (8.7%) and radiosurgery (2.9%). Almost half (43.8%) of dAVFs were completely obliterated. Of the 64 procedures, there were 19 neurological complications (29.7%) of varying severity where 12.5% were considered transient (i.e., pseudomeningocele) and 17.2% permanent (i.e., mortality secondary to acute sinus thrombosis, etc.). CONCLUSION: There is a paucity of information on pediatric dAVFs. This systematic review summarizes the published cases of dAVFs in the pediatric population. While the rate of missing data is high, there is publication bias, and precise details regarding complications are difficult to ascertain, this review serves as a descriptive summary of pediatric dAVFs.

PURPOSE: Epilepsy surgery for pediatric drug-resistant epilepsy has been shown to improve seizure control, enhance patient and family QoL, and reduce mortality. However, diagnostic tools and surgical capacity are less accessible worldwide. The International Society Pediatric Neurosurgery (ISPN) has established a Pediatric Epilepsy Surgery Interest Group (PESIG), aiming to enhance global collaboration in research and educational aspects. The goals of this manuscript are to introduce PESIG and analyze geographical differences of epilepsy surgery and technology availability. METHODS: PESIG was established (2022) following an ISPN executive board decision. Using a standardized form, we surveyed the PESIG members, collecting and analyzing data regarding geographical distribution, and availability of various epilepsy treatment-related technologies. RESULTS: Two hundred eighty-two members registered in PESIG from 70 countries, over 6 continents, were included. We categorized the countries by GDP as follows: low, lower-medium, upper-medium, and high income. The most commonly available technology was vagus nerve stimulation 68%. Stereoelectroencephalography was available for 58%. North America had statistically significant greater availability compared to other continents. Europe had greater availability compared to Africa, Asia, and South (Latin) America. Asia had greater availability compared to Africa. High-income countries had statistically significant greater availability compared to other income groups; there was no significant difference between the other income-level subgroups. CONCLUSION: There is a clear discrepancy between countries and continents regarding access to epilepsy surgery technologies. This strengthens the need for collaboration between neurologists and neurosurgeons from around the world, to enhance medical education and training, as well as to increase technological availability.

OBJECTIVE: Lennox-Gastaut syndrome (LGS) is a severe form of epileptic encephalopathy, presenting during the first years of life, and is very resistant to treatment. Once medical therapy has failed, palliative surgeries such as vagus nerve stimulation (VNS) or corpus callosotomy (CC) are considered. Although CC is more effective than VNS as the primary neurosurgical treatment for LGS-associated drop attacks, there are limited data regarding the added value of CC following VNS. This study aimed to assess the effectiveness of CC preceded by VNS. METHODS: This multinational, multicenter retrospective study focuses on LGS children who underwent CC before the age of 18 years, following prior VNS, which failed to achieve satisfactory seizure control. Collected data included epilepsy characteristics, surgical details, epilepsy outcomes, and complications. The primary outcome of this study was a 50% reduction in drop attacks. RESULTS: A total of 127 cases were reviewed (80 males). The median age at epilepsy onset was 6 months (interquartile range [IQR] = 3.12-22.75). The median age at VNS surgery was 7 years (IQR = 4-10), and CC was performed at a median age of 11 years (IQR = 8.76-15). The dominant seizure type was drop attacks (tonic or atonic) in 102 patients. Eighty-six patients underwent a single-stage complete CC, and 41 an anterior callosotomy. Ten patients who did not initially have a complete CC underwent a second surgery for completion of CC due to seizure persistence. Overall, there was at least a 50% reduction in drop attacks and other seizures in 83% and 60%, respectively. Permanent morbidity occurred in 1.5%, with no mortality. SIGNIFICANCE: CC is vital in seizure control in children with LGS in whom VNS has failed. Surgical risks are low. A complete CC has a tendency toward better effectiveness than anterior CC for some seizure types.

Corpus callosotomy (CC) is an effective surgical treatment for medically resistant generalized or multifocal epilepsy (MRE). The premise of CC extrapolates from the observation that the corpus callosum is the predominant commissural pathway that allows spread and synchroneity of epileptogenic activity between the hemispheres. Candidacy for CC is typically reserved for patients seeking palliative epilepsy treatment with the goal of reducing the frequency of drop attacks, although reduction of other seizure semiologies (absence, complex partial seizures, and tonic-clonic) has been observed. A reduction in morbidity affiliated with evolution of surgical techniques to perform CC has improved the safety profile of the procedure without necessarily sacrificing efficacy.

OBJECTIVE: The optimal extent of resection of craniopharyngiomas to minimize the long-term risks of hypothalamic and endocrine dysfunction (obesity and panhypopituitarism) in children remains uncertain. The purpose of this study was to report long-term outcomes of pediatric patients with craniopharyngioma undergoing surgical treatment and to study rates of endocrinological and hypothalamic dysfunction in association with extent of resection. METHODS: This retrospective study was performed in a cohort of children who underwent resection for craniopharyngioma at Children's of Alabama between 1990 and 2020. The primary outcome was hypothalamic dysfunction defined as a 0.5 increase in body mass index (BMI) Z-score and as a BMI > 2 SDs with or without psychiatric disturbances. Univariable analysis was performed using ANOVA, Wilcoxon rank-sum test, Pearson's chi-square test, and Fisher's exact test as appropriate. Missing data on the primary outcome were handled via multiple imputations. Relative risks were estimated using a multivariable generalized linear model with a priori variables selected using a modified Poisson regression approach with robust error variance to estimate risk ratios. RESULTS: The cohort includes 39 patients (24 girls and 15 boys; age range 1 month-16 years) who underwent resection of craniopharyngioma at the authors' center between 1990 and 2020. The preoperative goal of treatment was cyst decompression (CD) in 5, subtotal resection (STR) in 13, and gross-total resection (GTR) in 21 patients. The median long-term follow-up after surgery was 8.11 years (average 8.21, range 0.4-24.33 years). Univariate analysis demonstrated a statistically significant increase in hypothalamic dysfunction in patients undergoing GTR when compared to those undergoing STR or CD at 1 month postoperatively (p = 0.006) and 6-11 months postoperatively (p = 0.010), but with this difference not persisting beyond 1 year. Multivariable analysis showed patients older than 10 years at time of surgery to be the most affected and at highest risk of developing significant hypothalamic dysfunction. There was no significant difference in pituitary or neurological function between the STR/CD and GTR groups at 12-24 months or at most recent follow-up. There was no significant difference in BMI Z-scores between the STR/CD and GTR groups at 6-12 months or at most recent follow-up. CONCLUSIONS: Both STR and GTR of craniopharyngioma were associated with significant endocrinological sequelae after 1 year. These potential complications should be discussed with patients and their families, and postoperative protocols should include early nutritional and endocrinological interventions with endocrinologist consultation.

OBJECTIVE: Hemispherectomy is highly effective for patients with medically refractory epilepsy (MRE) arising from a single hemisphere. Recently, the Hemispherectomy Outcome Prediction Scale (HOPS) was developed as a prediction tool for seizure freedom after hemispherectomy. The authors' goal was to perform a validation study to determine the generalizability of the HOPS score. METHODS: The authors present an observational, retrospective, 20-year, single-institution, two-surgeon experience using the lateral peri-insular hemispherectomy approach to validate the HOPS score. Variables used to derive the HOPS score included seizure onset age, semiology, PET hypometabolism, seizure substrate, and history of prior epilepsy resection. Multivariable logistic regression, multiple imputation, and Bayesian analyses were used to determine validity. RESULTS: The authors' cohort comprised 60 patients; 55% of patients were male and 78% were Caucasian. The median age at first hemispherectomy surgery was 72 months. At 1 year postoperatively, 80% of patients had Engel class I outcomes, analogous to most contemporary series. All patients who experienced seizure recurrence after hemispherectomy did so within the first 2 years postoperatively. Sixteen (27%) and 10 (17%) patients had contralateral MRI findings and hypometabolism on PET, respectively. Both a multivariable logistic regression model using HOPS score variables (model p = 0.2588) and a revised model that included contralateral MRI findings (model p = 0.4715) were not statistically significant in this cohort. Bayesian analysis also did not validate the HOPS score. CONCLUSIONS: While seizure outcome prediction tools may be helpful for counseling patients about postoperative outcomes, rigorous validity and reliability testing are required. Prospective, standardized, and longitudinal evaluation of patients undergoing hemispherectomy are needed.
RESUMEN
OBJECTIVE: The authors analyzed the National Spina Bifida Patient Registry (NSBPR), a national registry that tracks the outcomes for people with various forms of spinal dysraphism, to determine the ongoing longitudinal risk for tethered cord release (TCR) among adults with myelomeningocele who had not previously undergone TCR during childhood. The authors also sought to identify the impact of lesion level, ambulation status, and prior treatments for hydrocephalus or Chiari malformations on TCR rates. METHODS: Adults in the registry who had not previously undergone TCR during childhood were studied. This group was compared with the remaining adults in the registry. The frequency of first-time TCR and time to TCR (using Kaplan-Meier analysis) were determined independently for males and females. Cox proportional hazards analysis identified correlations between sex, best lesion level and ambulation status prior to TCR, and previous treatments for hydrocephalus and Chiari decompression. RESULTS: Among 967 adults in the NSBPR (422 [43.6%] males and 545 [56.4%] females) who had not undergone TCR during childhood, the authors identified 47 people (4.9%) who underwent their first TCR during adulthood. This study cohort had significantly better mean functional motor levels and ambulation compared with the remaining adult cohort (both p < 0.001). The study group included 35 females (74.5%) and 12 males (25.5%); this sex distribution was significantly different in comparison with the remaining adult cohort (p = 0.016). The Kaplan-Meier curves for first TCR for females and males were significantly different (p = 0.01, log-rank test). TCR rates were correlated with sex (males had decreased risk; OR 0.31, 95% CI 0.16-0.62, p < 0.001), prior treatment for hydrocephalus (those who underwent prior treatment had decreased risk; OR 0.21, 95% CI 0.20-0.42, p < 0.001), and prior treatment for Chiari malformation (those who underwent prior treatment had greater risk; OR 3.84, 95% CI 1.50-9.88, p = 0.005). CONCLUSIONS: Adults with myelomeningocele who escape childhood without undergoing TCR have an ongoing, albeit decreased, risk for spinal cord tethering requiring TCR. This risk is obviously not due to spinal column growth and therefore must reflect other factors such as dynamic changes in spinal cord health over time. Among people with MMC who underwent their first TCR as adults, females seemed to be overrepresented. Similar to the authors' prior childhood study, people who underwent previous Chiari decompression seemed to be overrepresented, whereas those who underwent previous treatment for hydrocephalus seem to be underrepresented. These novel findings deserve further study.

Spina bifida (SB) remains the most serious and most common congenital anomaly of the human nervous system that is compatible with life. The open myelomeningocele on the back is perhaps the most obvious initial problem, but the collective impact of dysraphism upon the entirety of the nervous system and innervated organs is an equal or greater longitudinal threat. As such, patients with myelomeningocele (MMC) are best managed in a multi-disciplinary clinic that brings together experienced medical, nursing, and therapy teams that provide high standards of care while studying outcomes and sharing insights and experiences. Since its inception 30 years ago, the spina bifida program at UAB/Children's of Alabama has remained dedicated to providing exemplary multi-disciplinary care for affected children and their families. During this time, there has been great change in the care landscape, but many of the neurosurgical principles and primary issues have remained the same. In utero myelomeningocele closure (IUMC) has revolutionized initial care and has favorable impact on several important co-morbidities of SB including hydrocephalus, the Chiari II malformation, and the functional level of the neurologic deficit. Hydrocephalus however is not solved by IUMC, and hydrocephalus management remains at the center of neurosurgical care in SB. Ventricular shunts were long the cornerstone of treatment for hydrocephalus, but we came to assess and incorporate endoscopic third ventriculostomy with choroid plexus coagulation (ETV-CPC). Educated and nurtured by an experienced senior mentor, we dedicated ourselves to fundamental concepts but persistently evaluated our care outcomes and evolved our protocols and paradigms for improvement. Active conversations amidst networks of treasured colleagues were central to this development and growth. While hydrocephalus support and treatment of tethered spinal cord remained our principal neurosurgical charges, we evolved to embrace a holistic perspective and approach that is reflected and captured in the Lifetime Care Plan. Our team engaged actively in important workshops and guideline initiatives and was central to the development and support of the National Spina Bifida Patient Registry. We started and developed an adult SB clinic to support our patients who aged out of pediatric care. Lessons there taught us the importance of a model of transition that emphasized personal responsibility and awareness of health and the crucial role of dedicated support over time. Support for sleep, bowel health, and personal intimate cares are important contributors to overall health and care. This paper details our growth, learning, and evolution of care provision over the past 30 years.

Neurosurgical advocates for global surgery/neurosurgery at the 75th World Health Assembly gathered in person for the first time after the COVID-19 pandemic in Geneva, Switzerland, in May 2022. This article reviews the significant progress in the global health landscape targeting neglected neurosurgical patients, emphasizing high-level policy advocacy and international efforts to support a new World Health Assembly resolution in mandatory folic acid fortification to prevent neural tube defects. The process of developing global resolutions through the World Health Organization and its member states is summarized. Two new global initiatives focused on the surgical patients among the most vulnerable member states are discussed, the Global Surgery Foundation and the Global Action Plan on Epilepsy and other Neurological Disorders. Progress toward a neurosurgery-inspired resolution on mandatory folic acid fortification to prevent spina bifida-folate is described. In addition, priorities for moving the global health agenda forward for the neurosurgical patient as it relates to the global burden of neurological disease are reviewed after the COVID-19 pandemic.
