Abstract	Open spina bifida (OSB) is a common neural tube defect. Medical and surgical care involves addressing the baseline orthopedic, urologic, and neurological dysfunction as well as the changes or declines that may occur as the patient ages. Given the complexity of this disease, coordinated, multidisciplinary care involving specialists in neurosurgery, orthopedics, urology, rehabilitation and physical medicine, pediatrics, and psychology is necessary to establish and optimize baseline function. Traditionally in the US, pediatric multispecialty spina bifida clinics have provided the patient with a coordinated medical support system. Unfortunately, this coordinated, medical home has been difficult to establish during the transition from pediatric to adult care. Medical professionals must have a strong understanding of OSB to properly manage the disease and detect and prevent associated complications. In this manuscript, we (1) describe the changing needs and challenges of people living with OSB over a lifespan, (2) delineate current practices in the transition of care for people with OSB from childhood to adulthood, and (3) provide recommendations for best practices in navigating the transition process for clinicians who provide care for those afflicted with this most complex congenital abnormality of the nervous system compatible with long term survival.

Abstract	Background and objectives: While spinal cord neurapraxia (SCN) is a documented pathology in athletes, guidance for neurosurgeons evaluating these patients is sparse. Therefore, in a cohort of adolescent athletes with SCN, we sought to (1) review their presentation and management and (2) describe outcomes and return-to-play (RTP). Methods: A single-center, retrospective case series was conducted to examine adolescent athletes diagnosed with SCN from 2017 to 2022. SCN was defined as an episode of bilateral upper and/or lower extremity weakness/numbness after an impact during sport. Collected variables included demographics, presentation, management, outcomes, and RTP. Results: Six patients were included (mean age = 14.5 ± 2.1 years, 100.0% male). Three American football players sustained tackle injuries, 1 ice hockey and 1 basketball player fell and landed on their head/neck, and 1 weight lifter sustained an axial load of weights to his neck. Motor symptoms ranged from quadriplegia to partial weakness. Full symptom resolution was seen in 6/6 patients: in <1 day for 3 patients, 2-3 days for 2 patients, and 1-2 months for 1 patient. All 6/6 patients received computed tomography of head/cervical spine and MRI of cervical spine, half of whom received computed tomography and MRI of thoracic/lumbar spine. No patient had congenital stenosis or abnormal T2 signal on MRI. Specific RTP recommendations varied. All 6 patients/parents were contacted at a mean of 16.6 ± 2.6 months from the injury. All patients returned to play at a mean of 5.7 ± 3.3 months. All 6 patients returned to their previous sports. Across all patients, no recurrence or neurological sequelae was endorsed in the follow-up period. Conclusion: Six athletes with SCN with no imaging abnormalities and full symptom resolution were able to RTP to their previous sport without future consequence. Symptom duration may not be clinically useful in determining the feasibility of RTP. Follow-up studies are warranted in this patient cohort to standardize RTP recommendations.

Abstract	Objective: Most studies regarding sport-related concussion (SRC) focus on high school and collegiate athletes; however, little has been published on children younger than 12 years of age. In a cohort of children aged 8-12 years with SRC, the authors sought to describe demographics, initial presentation, and recovery in this understudied population. Methods: A retrospective cohort study of children aged 8-12 years who sustained an SRC between November 2017 and April 2022 and were treated at a regional sports concussion center was conducted. Demographic information, injury characteristics, traditional Sport Concussion Assessment Tool 5 (SCAT5) and Child/Parent SCAT5 scores, and outcomes, defined as days to return to learn (RTL), symptom resolution, and return to play (RTP), were reported. Outcomes in boys and girls were compared using effect size analyses given sample size constraints. Results: Forty-seven athletes were included. The mean age was 11.0 ± 0.8 years, and the majority were male (34, 72.3%). A sizable proportion of patients visited an emergency department (19, 40.4%), and many received head imaging (16, 34.0%), mostly via CT (n = 13). The most common sport for boys was football (15, 44.1%), and the most common sports for girls were soccer (4, 30.8%) and cheerleading (4, 30.8%). These athletes reported a variety of symptoms on presentation. It took a mean of 8.8 ± 10.8 days to RTL, 27.3 ± 38.3 days to reach symptom resolution, and 35.4 ± 41.9 days to RTP. When comparing boys versus girls, there appeared to be moderate differences in symptom severity scores (Cohen's d = 0.44 for SCAT5, 0.13 for Child SCAT5, and 0.38 for Parent SCAT5) and minimal differences in recovery (Cohen's d = 0.11 for RTL, n = 35; 0.22 for symptom resolution, n = 22; and 0.12 for RTP, n = 21). Conclusions: In this cohort of concussed athletes aged 8-12 years, a little less than half of the athletes initially presented to the emergency department, and approximately one-third received acute head imaging. Across all athletes, the mean RTL was slightly more than a week and the mean symptom resolution and RTP were both approximately 1 month; however, much of the cohort is missing recovery outcome measures. This study demonstrated a strong positive correlation between Child SCAT5 and Parent SCAT5 symptom reporting. Future efforts are needed to evaluate differences in clinical presentation and outcomes following SRC between children and older populations.

Abstract	Objectives: The acute cerebral physiologic effects of ketamine in children have been incompletely described. We assessed the acute effects of ketamine on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in children with severe traumatic brain injury (TBI). Design: In this retrospective observational study, patients received bolus doses of ketamine for sedation or as a treatment for ICP crisis (ICP > 20 mm Hg for > 5 min). Administration times were synchronized with ICP and CPP recordings at 1-minute intervals logged in an automated database within the electronic health record. ICP and CPP were each averaged in epochs following drug administration and compared with baseline values. Age-based CPP thresholds were subtracted from CPP recordings and compared with baseline values. Trends in ICP and CPP over time were assessed using generalized least squares regression. Setting: A 30-bed tertiary care children's hospital PICU. Patients: Children with severe TBI who underwent ICP monitoring. Interventions: None. Measurements and main results: We analyzed data from 33 patients, ages 1 month to 16 years, 22 of whom received bolus doses of ketamine, with 127 doses analyzed. Demographics, patient, and injury characteristics were similar between patients who did versus did not receive ketamine boluses. In analysis of the subset of ketamine doses used only for sedation, there was no significant difference in ICP or CPP from baseline. Eighteen ketamine doses were given during ICP crises in 11 patients. ICP decreased following these doses and threshold-subtracted CPP rose. Conclusions: In this retrospective, exploratory study, ICP did not increase following ketamine administration. In the setting of a guidelines-based protocol, ketamine was associated with a reduction in ICP during ICP crises. If these findings are reproduced in a larger study, ketamine may warrant consideration as a treatment for intracranial hypertension in children with severe TBI.

Abstract	Objective: Pediatric isolated linear skull fractures commonly result from head trauma and rarely require surgery, yet patients are often admitted to the hospital-a costly care plan. In this study, the authors utilized a national database to investigate trends in admission for skull fractures across the United States. Methods: Children younger than 18 years with isolated linear skull fracture, according to ICD-9 diagnosis codes in the Kids' Inpatient Database of the Healthcare and Utilization Project (HCUP), who presented between 2003 and 2016 were included. HCUP collected data in 2003, 2006, 2009, 2012, and 2016. Children with a depressed skull fracture, multiple traumatic injuries, and acute intracranial findings were excluded. Sample-level data were translated into population-level data by using an HCUP-specific discharge weight. Results: Overall, 11,355 patients (64% males) were admitted to 1605 hospitals. National admissions decreased from 3053 patients in 2003 to 1203 in 2016. The mean ± SD age at admission also decreased from 6.3 ± 5.9 years to 1.2 ± 3.0 years (p < 0.001). The proportion of patients in the lowest quartile of median household income increased by 9%, while that in the highest income quartile decreased by 7% (p < 0.001). Admission was generally more common in the summer months (June, July, and August) and on weekdays (68%). The mean ± SD hospital length of stay decreased from 2.0 ± 3.1 days to 1.4 ± 1.4 days between 2003 and 2012, and then increased to 2.1 ± 6.8 days in 2016 (p < 0.001). When adjusted for inflation, the mean total hospital charges increased from $13,099 to $21,204 (p < 0.001). The greatest proportion of admissions was in the South (35%), and the lowest was in the Northeast (17%). The proportion of patients admitted to large hospitals increased (59% to 72%, p < 0.001), which corresponded to a decrease in patients admitted to small hospitals (16% to 9%, p < 0.001). Overall, the total proportion of admissions to rural hospitals decreased by 6%, and that to urban teaching centers increased by 15% (p < 0.001). Since 2003, no child has undergone a neurosurgical procedure or died as an inpatient. Conclusions: This study identified a general nationwide decrease in admissions for pediatric linear isolated skull fracture, but associated costs increased. Admissions became less common at smaller rural hospitals and more common at larger urban teaching hospitals. This patient population required no inpatient neurosurgical intervention after 2003.

Abstract	Objective: Isolated linear skull fractures without intracranial findings rarely require urgent neurosurgical intervention. A multidisciplinary fracture management protocol based on antiemetic usage was implemented at our American College of Surgeons-verified level 1 pediatric trauma center on July 1, 2019. This study evaluated protocol safety and efficacy. Methods: Children younger than 18 years with an ICD-10 code for linear skull fracture without acute intracranial abnormality on head CT were compared before and after protocol implementation. The preprotocol cohort was defined as children who presented between July 1, 2015, and December 31, 2017; the postprotocol cohort was defined as those who presented between July 1, 2019, and July 1, 2020. Results: The preprotocol and postprotocol cohorts included 162 and 82 children, respectively. Overall, 57% were male, and the median (interquartile range) age was 9.1 (4.8-25.0) months. The cohorts did not differ significantly in terms of sex (p = 0.1) or age (p = 0.8). Falls were the most common mechanism of injury (193 patients [79%]). After protocol implementation, there was a relative increase in patients who fell from a height > 3 feet (10% to 29%, p < 0.001) and those with no reported injury mechanism (12% to 16%, p < 0.001). The neurosurgery department was consulted for 86% and 44% of preprotocol and postprotocol cases, respectively (p < 0.001). Trauma consultations and consultations for abusive head trauma did not significantly change (p = 0.2 and p = 0.1, respectively). Admission rate significantly decreased (52% to 38%, p = 0.04), and the 72-hour emergency department revisit rate trended down but was not statistically significant (2.8/year to 1/year, p = 0.2). No deaths occurred, and no inpatient neurosurgical procedures were performed. Conclusions: Protocolization of isolated linear skull fracture management is safe and feasible at a high-volume level 1 pediatric trauma center. Neurosurgical consultation can be prioritized for select patients. Further investigation into criteria for admission, need for interfacility transfers, and healthcare costs is warranted.

Abstract	Introduction: Many children are discharged from the pediatric emergency department (PED) with incomplete or inappropriate instructions following a concussion. Our objective was to evaluate the effectiveness of a simple intervention in improving discharge instruction disbursement and completeness following PED diagnosis of concussion. Methods: A pre/post intervention study of 935 patients (375 preintervention and 560 postintervention) ages 5-19, diagnosed with a concussion and discharged from the PED between July 2016 and November 2019, was performed at a single United States pediatric tertiary-care center. Dedicated provider education sessions were held, and a consensus guideline-based set of discharge instructions were implemented in the electronic health record. Primary outcomes included the presence of return-to-play (RTP) instructions, return-to-learn (RTL) instructions, follow-up recommendations, and "complete" discharge (ie, all 3 components present). Statistical process control charts were generated and tested for special cause variation. Results: More patients received instructions for RTP (87% versus 59%) and RTL (60% versus 3%), and a complete discharge was more frequent (45% versus 2%), following the conclusion of the intervention. Only the improvement in RTP instructions was completely sustained into the following academic year, whereas RTL and complete discharge rates declined to 27% and 20%, respectively. Conclusions: A simple, low-cost intervention such as peer-to-peer education and consensus guideline-based discharge instruction templates can significantly improve discharge readiness after pediatric concussion. Further work is needed to maintain progress and continue improvements, at our large academic trauma center.

Abstract	Objective: Open and endoscope-assisted repair are surgical options for sagittal craniosynostosis, with limited research evaluating each technique's immediate and long-term costs. This study investigates the cost-effectiveness of open and endoscope-assisted repair for single, sagittal suture craniosynostosis. Methods: The authors performed a retrospective cohort study of patients undergoing single, sagittal suture craniosynostosis repair (open in 17 cases, endoscope-assisted in 16) at less than 1 year of age at Monroe Carell Jr. Children's Hospital at Vanderbilt (MCJCHV) between August 2015 and August 2017. Follow-up data were collected/analyzed for 1 year after discharge. Surgical and follow-up costs were derived by merging MCJCHV financial data with each patient's electronic medical record (EMR) and were adjusted for inflation using the healthcare Producer Price Index. Proxy helmet costs were derived from third-party out-of-pocket helmet prices. To account for variable costs and probabilities, overall costs were calculated using TreeAge tree diagram software. Results: Open repair occurred in older patients (mean age 5.69 vs 2.96 months, p < 0.001) and required more operating room time (median 203 vs 145 minutes, p < 0.001), more ICU days (median 3 vs 1 day, p < 0.001), more hospital days (median 4 vs 1 day, p < 0.001), and more frequently required transfusion (88% vs 6% of cases). Compared to patients who underwent open surgery, patients who underwent endoscopically assisted surgery more often required postoperative orthotic helmets (100% vs 6%), had a similar number of follow-up clinic visits (median 3 vs 3 visits, p = 0.487) and CT scans (median 3 vs 2 scans), and fewer emergency department visits (median 1 vs 3 visits). The TreeAge diagram showed that, overall, open repair was 73% more expensive than endoscope-assisted repair ($31,314.10 vs $18,081.47). Sensitivity analysis identified surgical/hospital costs for open repair (mean $30,475, SEM $547) versus endoscope-assisted repair (mean $13,746, SEM $833) (p < 0.001) as the most important determinants of overall cost. Two-way sensitivity analysis comparing initial surgical/hospital costs confirmed that open repair remains significantly more expensive under even worst-case initial repair scenarios ($3254.81 minimum difference). No major surgical complications or surgical revisions occurred in either cohort. Conclusions: The results of this study suggest that endoscope-assisted craniosynostosis repair is significantly more cost-effective than open repair, based on markedly lower costs and similar outcomes, and that the difference in initial surgical/hospital costs far outweighs the difference in subsequent costs associated with helmet therapy and outpatient management, although independent replication in a multicenter study is needed for confirmation due to practice and cost variation across institutions. Longer-term results will also be needed to examine whether cost differences are maintained.

Abstract	Object: Because there is no gold standard for preoperative diagnosis of shunt failure, understanding the sensitivity, specificity, and predictive values of symptoms, signs, and diagnostic tests enables practitioners to make logical clinical decisions. Parents of children with shunts undergo educational instruction to enable them to recognize shunt failure. The authors prospectively investigated parental ability to recognize shunt failure. Methods: Data were prospectively collected on 205 consecutive encounters in 153 children with shunted hydrocephalus presenting to the emergency department or clinic, or as an inpatient consultation, to the Children's Hospital of Alabama between April and October 2010. Regardless of the complaint, all parents were asked if they believed the shunt was in failure. Six children were excluded from analysis because a parental response was lacking. Using the Shunt Design Trial definitions, shunt failure was diagnosed intraoperatively or ruled out if the child did not undergo shunt revision within 1 week of presentation. Sensitivity, specificity, predictive values, and accuracy were calculated using the parental response and shunt failure diagnosis. Secondarily, parents were compared based on their experience with shunt failure in their children; experienced parents were defined as having experienced at least 3 shunt failures. Post hoc analysis evaluated diagnostic test characteristics among hydrocephalus causes and compared parental recognition of shunt failure to head CT and shunt series diagnostic test characteristics. Parents also completed a standardized shunt failure survey regarding their shunt teaching education and symptom tracking. Results: Children enrolled were a mean age of 6.9 years old, 92 (46%) of the encounters were with male patients, and most patients were Caucasian (69%) and had undergone an average of 2.8 previous shunt revisions. Seventy-one children (36%) were diagnosed with shunt failure. Parental response diagnostic test characteristics were: positive predictive value (PPV) of 41%, negative predictive value (NPV) of 79%, sensitivity of 83%, specificity of 34%, and accuracy of 52% for shunt failure. Sixty-three parents were considered experienced and responded with a PPV of 29%, NPV of 92%, sensitivity of 94%, specificity of 23%, and accuracy of 41%. One hundred thirty-six parents were considered inexperienced and responded with a PPV of 48%, NPV of 75%, sensitivity of 80%, specificity of 41%, and accuracy of 57%. When statistically compared, experienced parents had significantly lower PPV (29% vs 48%, respectively; p = 0.035) and accuracy (41% vs 57%, respectively; p = 0.049) than inexperienced parents. On post hoc analysis, parental recognition of shunt failure was inferior to head CT and shunt series diagnostic tests with a lower specificity (20% vs 88%, respectively; p < 0.0005), PPV (44% vs 84%, respectively; p < 0.0005), NPV (61% vs 85%, respectively; p = 0.006), and accuracy (47% vs. 85%, respectively; p < 0.0005). Conclusions: The overall parental response had the greatest value in ruling out shunt failure, reflected in the high NPV, particularly in experienced parents. The head CT and shunt series provide more favorable diagnostic test characteristics than the parental response. Although educational interventions have decreased shunt-related deaths, parents have difficulty differentiating shunt failure from alternative diagnoses.
