Spina bifida outcome: a 25-year prospective

Prevalence of sexual abuse and intimate partner violence in adults with spina bifida

BACKGROUND

People with disabilities and chronic medical conditions are known to be at higher risk of sexual abuse (SA) and intimate partner violence (IPV). People with spina bifida (SB) are vulnerable, but little is known about the prevalence of abuse in this population.

OBJECTIVE

To evaluate the prevalence and risk factors of SA and IPV in adults with SB.

METHODS

An anonymous international cross-sectional online survey of adults with SB asked about history of SA ("sexual contact that you did not want") and IPV ("hit, slapped, kicked, punched or hurt physically by a partner").

RESULTS

Median age of the 405 participants (61% female) was 35 years. Most self-identified as heterosexual (85%) and were in a romantic relationship (66%). A total of 19% reported a history of SA (78% no SA, 3% preferred not to answer). SA was more frequently reported by women compared to men (27% vs. 5%, p < 0.001) and non-heterosexual adults compared to heterosexuals (41% vs. 15%, p < 0.001). Twelve percent reported a history of IPV (86% no IPV, 2% preferred not to answer). IPV was more frequently reported by women compared to men (14% vs. 9%, p = 0.02), non-heterosexuals compared to heterosexuals (26% vs. 10%, p = 0.002), and adults with a history of sexual activity versus those without (14% vs. 2%, p = 0.01).

CONCLUSION

People with SB are subjected to SA and IPV. Women and non-heterosexuals are at higher risk of both.

Fetal surgery for open neural tube defect with severe ventriculomegaly

OBJECTIVE

Prenatal open neural tube defect (ONTD) repair is performed to decrease the risk of needing treatment for hydrocephalus after birth and to preserve motor function. Some centers may not consider patients to be candidates for surgery if severe ventriculomegaly is present and there is no expected benefit in risk for hydrocephalus treatment. This study sought to compare the postnatal outcome of fetuses with ONTD and severe ventriculomegaly (ventricular width ≥ 15 mm) that underwent prenatal repair with the outcome of fetuses with severe ventriculomegaly that underwent postnatal repair and fetuses without severe ventriculomegaly (< 15 mm) that underwent prenatal repair.

METHODS

This was a retrospective study of fetuses with ONTD that underwent prenatal or postnatal repair between 2012 and 2021 at a single institution. The cohort was divided into two groups based on preoperative fetal ventricular size: those with severe ventriculomegaly (ventricular width ≥ 15 mm) and those without severe ventriculomegaly (< 15 mm). Fetal ventricular size was measured by magnetic resonance imaging before surgery using the standardized approach and the mean size of the left and right ventricles was used for analysis. Motor function of the lower extremities was assessed at the time of referral by ultrasound and if flexion-extension movements of the ankle were seen it was considered as preserved S1 motor function. Postnatal outcomes, including motor function of the lower extremities at birth and the need for a diversion procedure for hydrocephalus treatment during the first year after birth, were collected and compared between groups. Multivariate regression analysis was used to adjust for potential confounders.

RESULTS

In this study, 154 patients were included: 145 underwent fetal surgery (101 fetoscopic and 44 open hysterotomy) and nine with severe ventriculomegaly underwent postnatal repair. Among the 145 patients who underwent fetal surgery, 22 presented with severe ventriculomegaly. Fetuses with severe ventriculomegaly at referral that underwent prenatal repair were significantly more likely to need hydrocephalus treatment by 12 months after birth than those without severe ventriculomegaly (61.9% vs 28.9%, P < 0.01). However, motor function assessment at birth was similar between both prenatal repair groups (odds ratio, 0.92 (95% CI, 0.33-2.59), P = 0.88), adjusted for the anatomical level of the lesion. The prenatal repair group with severe ventriculomegaly had better preserved motor function at birth compared to the postnatal repair group with severe ventriculomegaly (median level, S1 vs L3, P < 0.01; proportion with S1 motor function, 68.2% vs 11.1%, P < 0.01). Fetuses with severe ventriculomegaly that underwent prenatal repair had an 18.9 (95% CI, 1.2-290.1)-times higher chance of having intact motor function at birth, adjusted for ethnicity, presence of club foot at referral and gestational age at delivery, compared with the postnatal repair group. There was no significant difference in the need for hydrocephalus treatment in the first year after birth between prenatal and postnatal repair groups with severe ventriculomegaly (61.9% vs 87.5%, P = 0.18).

CONCLUSIONS

Although fetuses with ONTD and severe ventriculomegaly do not seem to benefit from fetal surgery in terms of postnatal hydrocephalus treatment, there is an increased chance of preserved motor function at birth. Results from this study highlight the benefit of prenatal ONTD repair for cases with severe ventriculomegaly at referral to preserve motor function. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Proposal for standardized prenatal assessment of fetal open dysraphisms by the European reference network for Intellectual disability, TeleHealth, Autism and Congenital Anomalies (ITHACA) and eUROGEN

Open dysraphisms, that is, myelomeningocele and myeloschisis, are rare diseases associated with a risk of severe disability, including lower limb motor and sensory deficiency, sphincter deficiency, and potential intellectual deficiency. Open dysraphism is diagnosed in Europe in 93.5% of cases. In case of suspicion of fetal open dysraphism, a detailed fetal morphologic assessment is required to confirm the diagnosis and exclude associated structural anomalies, as well as genetic assessment. In case of isolated fetal open dysraphism, assessment of prognosis is based on fetal imaging including the level of the lesion, the presence or not of a sac, the presence and nature of intra cranial anomalies, and the anatomical and functional evaluation of the lower extremities. Based on these biomarkers, a personalized prognosis as well as comprehensive information about prenatal management alternatives will allow parents to decide on further management options. Standardization of prenatal assessment is essential to compare outcomes with benchmark data and make assessment of surgical innovation possible. Herein, we propose a protocol for the standardized ultrasound assessment of fetuses with isolated open dysraphism.

The Montana Postural Care Project: A pilot study implementing posture care management in a rural, low-resource region

Background

Mobility impairment limits control of posture and body alignment. This leads to altered body shapes, co-occurring problems with pain and sleep, cardiopulmonary concerns, digestive health issues, and emergent health outcomes, which further complicate functions of daily living. 24-hour posture care management was developed to remedy these challenges by restoring body symmetry.

Objective

To determine the feasibility of introducing posture care management to a rural-based, medically complex patient population, evaluate response of body symmetry, and examine its impact on pain and sleep quality.

Methods

This pilot study employed a longitudinal, quasi-experimental study design from March 2016 to September 2018. The posture care management intervention introduced positioning support for use when lying down, a personalized training workshop for caregiver teams, and in-home initial and follow-up assessments to provide materials and collaboratively develop a personalized care plan. Participants were followed pre-post for 6-9 months.

Results

A total of 73 participants enrolled in the study; 55 (75 %) completed. The majority were male (55 %) with a median age of 11. Most caregivers were immediate family members, and most participants had 1+ diagnosis characterized as a neurodevelopmental disorder. A majority of participants improved body symmetry (56-76 %), and 53 % with comparable information saw improvement in body symmetry with no worsening of pain or sleep quality.

Conclusion

This study established the feasibility of administering posture care management in North America. These findings provide preliminary evidence of improvements in body symmetry and address concerns that posture care management can interfere with pain and sleep. Future research should consider levels of caregiver engagement and explore remote-monitored options of a posture care management intervention.

Determinants of neural tube defect among newborns admitted to neonatal intensive care units of teaching hospitals in Gedeo Zone and Sidama Region, Southern Ethiopia: a case-control study

BACKGROUND

Neural tube defects are a significant cause of morbidity and mortality that can occur in the early pregnancy periods. Though the burden is high, it gains only limited attention. In Ethiopia, the estimated number of neural tube defect cases was significantly higher. So, identifying factors contributing to it would be significant for planning risk reduction and preventive strategies. Therefore, identifying the possible determinants was aimed at this study.

METHODS

A hospital-based, unmatched case-control study was conducted on 104 cases and 208 controls selected from neonatal intensive care units of teaching hospitals in Gedeo Zone and Sidama Region, southern Ethiopia from December 2021 to November 2022. All neural tube defect cases were included consecutively and controls were selected by using a simple random sampling method. Data were collected using interviewer-administered semistructured questionnaires. Data analysis was done by using SPSS V.25. Binary logistic regression was used, and variables with a p value less than 0.25 in bivariate analysis were entered into the multivariable logistic regression model. An adjusted OR with a 95% CI was estimated, and finally, variables that show a level of p value less than 0.05 in multivariable analysis were declared statistically significant.

RESULT

After controlling confounders, factors such as unplanned pregnancy 2.20 (95% CI 1.20 to 4.041), history of abortions 2.09 (95% CI 1.19 to 3.67), khat chewing 6.67 (95% CI 2.95 to 15.06), antipyretic and analgesic medications 2.87 (95% CI 1.47 to 5.56) and, being a female neonate 2.11 (95% CI 1.21 to 3.67) were significantly associated with a neural tube defect.

CONCLUSION

This study has identified some determinants of neural tube defects. Hence, the behavioural, medical and obstetrical conditions of mothers need serious evaluation in the prepregnancy period. So, improving preconception counselling and prenatal care practices would have a significant role in reducing the risk of neural tube defects.

Isokinetic arm and shoulder muscle torque-velocity characteristics in mobility limited children and adolescents with spina bifida

INTRODUCTION

Propulsive wheelchair capacity may be influenced by arm muscle performance.Objectives: To determine whether children and adolescent wheelchair-users with spina bifida show reduced arm muscle strength compared to their typically developing peers and to compare muscle strength data obtained by isokinetic and handheld dynamometry (HHD).

METHODS

Participants (mean age 12.5 ± 2.5 years) were assigned to spina bifida (SB; n = 11) or control (n = 22) groups. Isokinetic dynamometry was used to measure peak torque (PT) during dynamic (60°s-1 and 120°s-1) and isometric strength testing (MVIC) for shoulder and elbow flexors and extensors. HHD was used to measure MVIC of the same muscle groups.

RESULTS

SB showed reduced isokinetic PT for shoulder extensors at 60°s-1 and 120°s-1, shoulder flexor MVIC, and elbow flexors at 60°s-1 and MVIC; higher PT for shoulder flexors and elbow flexors at 120°s-1; and decreased MVIC for elbow flexors but not extensors compared to controls when assessed by HHD. The SB and control groups showed strong positive correlations between MVIC data obtained by the two devices for all muscle groups (r ≥ 0.81; p < .01), except for shoulder flexor MVIC in controls (r = 0.68; p < .01).

CONCLUSION

SB presented reduced levels of dynamic slow-speed and isometric shoulder and elbow muscle strength and greater dynamic high-speed shoulder and elbow flexor strength than controls possibly due to the exposure to self-sustained wheelchair ambulation. Exercise-based intervention protocols to increase slow-speed arm muscle strength should be considered in youth with SB. Strong positive correlations observed between muscle strength assessed by isokinetic dynamometry and HHD support the use of HHD in this clinical population.

Factors Associated with Transfer Distance from Birth Hospital to Repair Hospital for First Surgical Repair among Infants with Myelomeningocele in California

OBJECTIVE

 The objective of our study was to examine factors associated with distance to care for first surgical repair among infants with myelomeningocele in California.

STUDY DESIGN

 A total of 677 eligible cases with complete geocoded data were identified for birth years 2006 to 2012 using data from the California Perinatal Quality Care Collaborative linked to hospital and vital records. The median distance from home to birth hospital among eligible infants was 9 miles, and from birth hospital to repair hospital was 15 miles. We limited our analysis to infants who lived close to the birth hospital, creating two study groups to examine transfer distance patterns: "lived close and had a short transfer" (i.e., lived <9 miles from birth hospital and traveled <15 miles from birth hospital to repair hospital; n = 92), and "lived close and had a long transfer" (i.e., lived <9 miles from birth hospital and traveled ≥15 miles from birth hospital to repair hospital; n = 96). Log-binomial regression was used to estimate crude and adjusted risk ratios (aRRs and 95% confidence intervals (CIs). Selected maternal, infant, and birth hospital characteristics were compared between the two groups.

RESULTS

 We found that low birth weight (aRR = 1.44; 95% CI = 1.04, 1.99) and preterm birth (aRR = 1.41; 95% CI = 1.01, 1.97) were positively associated, whereas initiating prenatal care early in the first trimester was inversely associated (aRR = 0.64; 95% CI = 0.46, 0.89) with transferring a longer distance (≥15 miles) from birth hospital to repair hospital. No significant associations were noted by maternal race-ethnicity, socioeconomic indicators, or the level of hospital care at the birth hospital.

CONCLUSION

 Our study identified selected infant factors associated with the distance to access surgical care for infants with myelomeningocele who had to transfer from birth hospital to repair hospital. Distance-based barriers to care should be identified and optimized when planning deliveries of at-risk infants in other populations.

KEY POINTS

· Low birth weight predicted long hospital transfer distance.. · Preterm birth was associated with transfer distance.. · Prenatal care was associated with transfer distance..

The Role of Upper Extremity Motor Function in the Choice of Bladder Management in Those Unable to Volitionally Void due to Neurologic Dysfunction

It is estimated that 425,000 individuals with neurologic bladder dysfunction (spinal cordinjury, spina bifida and multiple sclerosis) are unable to volitionally void and must rely oncatheter drainage. Upper extremity (UE) motor function is one of the most important factors indetermining the type of bladder management chosen in individuals who cannot volitionally void. Novel bladder management solutions for those with impaired UE motor function and concurrent impairments involitional voiding continue to be an area of need. Those with poor UE motor function more often choose an indwelling catheter, whereas those with normal UE motor function more often choose clean intermittent catheterization.

Urinary and Fecal Incontinence During Sexual Activity Is Common and Bothersome Among Adults With Spina Bifida

OBJECTIVE

To evaluate the prevalence of and risk factors for urinary fecal incontinence (UI, FI) during sexual activity (UIS, FIS) among adults with spina bifida (SB).

METHODS

An international online survey of adults with SB was administered through SB clinics and SB organizations via social media. Adults with a history of masturbation or partnered sexual activity were included. The primary outcome was ever experiencing UIS/FIS. Nonparametric tests and logistic regression were used for analysis.

RESULTS

A total of 341 adults met inclusion criteria (median age: 36years, 59% female, 52% shunted, 48% community ambulators). Baseline UI in the last 4weeks was reported by 50% and FI by 41%. Nineteen (5%) had a urostomy. Eight (2%) had a colostomy. Overall, 93% had a history of partnered genital contact. Among adults without a diversion, UIS was more common than FIS (70% vs 45%, P < .001). Among adults without a urostomy, UIS was more common among women (76% vs 62%, P = .01) and those with baseline UI (84% vs 50%, P < .001). UIS was not associated with age, shunt, ambulatory, or catheterization status (P >=.32). On bivariate analysis, female sex and baseline UI were independent predictors of UIS (P <=.001). Among adults without a colostomy, FIS was associated with female sex (50% vs 39%, P = .046), baseline FI (59% vs 32%, P < .001), community ambulation (52% vs 40%, P = .04), but not age, shunt, or MACE status (P >=.27). On multivariate analysis, baseline FI was independently associated with FIS (P < .001). Among adults with UIS/FIS, 29% experienced UIS "almost always" to "always," compared to 5% for FIS (P < .001). Virtually all adults found UIS/FIS bothersome (>=96% for each), even when incontinence occurred "almost never." UIS/FIS mostly occurred before and/or during orgasm than afterward (P < .001). UIS was reported by 53% of adults with a urostomy (100% bothersome). FIS was reported by 38% of adults with a colostomy (100% bothersome).

CONCLUSION

Incontinence during sexual activity is a common problem for men and women with SB. Baseline incontinence is an independent, but not absolute, predictor of both. While FIS is less frequent than UIS, both are virtually always bothersome.

Double Myelomeningocele Repair by Fetal Surgery with a Single Micro-Hysterotomy

INTRODUCTION

Open spina bifida (OSB) is the most common congenital anomaly of the central nervous system. It is associated with severe neurodevelopmental delay, motor impairment, hydrocephalus, and bowel and bladder dysfunction. In selected cases, intrauterine spina bifida repair has been shown to improve neonatal outcomes. Rarely, the spine can have a double defect compromising two different segments and there is a lack of evidence on the feasibility and benefits of intrauterine repair in these cases.

CASE PRESENTATION

We present a case with both cervicothoracic and lumbosacral myelomeningocele, Arnold-Chiari malformation type II and bilateral ventriculomegaly, that was treated successfully at 25 weeks with open micro-neurosurgery. Double myelomeningocele was successfully treated through a single 2-cm micro-hysterotomy, by performing external versions to sequentially expose and repair both defects. Weekly postoperative follow-up showed no progression of ventriculomegaly or complications attributable to the procedure. Preterm rupture of membranes prompted a conventional cesarean delivery at 32 weeks of gestation. Neurodevelopmental outcome at 20 months was within normal ranges, having achieved ambulation without orthopedic support and with no need for ventriculoperitoneal shunting.

CONCLUSION

This report demonstrates for the first time the feasibility of double OSB repair through a single 2-cm micro-hysterotomy, suggesting that selected isolated cases of double myelomeningocele could be candidates for fetal intervention. Further prospective studies should be carried out to assess the potential benefit of double OSB intrauterine open repair.

Myelomeningocele: Long-Term Neurosurgical Management

Open spina bifida, also known as myelomeningocele (MMC), is the most challenging and severe birth defect of the central nervous system compatible with life and it is due to a failure in the dorsal fusion of the nascent neural tube during embryonic development. MMC is often accompanied by a constellation of collateral conditions, including hydrocephalus, Arnold - Chiari II malformation, brainstem disfunction, hydrosyringomyelia, tethered cord syndrome and scoliosis. Beyond early surgical repair of the dorsal defect, MMC requires lifelong cares. Several additional surgical procedures are generally necessary to improve the long-term outcomes of patients affected by MMC and multidisciplinary evaluations are crucial for early identification and management of the various medical condition that can accompany this pathology. In this chapter, the most common pathological entities associated with MMC are illustrated, focusing on clinical manifestations, treatment strategies and follow up recommendations.

Clinical presentation and outcomes of neonates born with neural tube defects- an experience from a level III B NICU in Western India

PURPOSE

Neural tube defects (NTDs) are one of the most common congenital anomalies and a cause of chronic disability. The study was done to study outcomes of neural tube defects admitted at a tertiary level neonatal intensive care unit (NICU) from 2018 to 2022, a period of 4 years that also coincided with the COVID pandemic. The secondary outcome was to study the clinical presentation, associated anomalies and epidemiological features.

METHODS

It was a retrospective observational study; data of infants was obtained from medical records and analysis was done.

RESULTS

Thirty-four neonates were enrolled, of which there were 16 (47%) males and 18 (53%) females. History of pre-pregnancy maternal folate intake was present in 4 (11.7%) cases. 33 (97%) babies were diagnosed with meningomyelocele (MMC) and one each had anencephaly, iniencephaly and encephalocele, of which one had frontal and two had occipital encephalocele. The median age of surgery was 16 days of life with primary repair being the most common procedure followed by MMC repair with VP shunt. Twenty babies (58.8%) were discharged successfully, while 9 (26.5%) expired and 5 (14.7%) were discharged against medical advice; which can be attributed to the financial problems of the patients in a developing country. The overall deaths in our series were four (26.5%) which is slightly higher than other studies which may be due to the fact that this study was conducted during the COVID era with lesser rates of folate supplementation, reduced access to prenatal diagnosis coupled with poor follow-up and compliance of patients post-surgical repair.

CONCLUSION

This study emphasizes the importance of periconceptional folic acid supplementation, prenatal diagnosis, early surgery and meticulous follow-up as being pivotal to improving outcomes in children with NTDs.

Transitioning care for adolescents with spina bifida in the US: challenges for management

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.

Myelomeningocele: the evolution of care over the last 50 years

PURPOSE

Myelomeningocele (MMC) is one of the representative anomalies in the field of pediatric neurosurgery. During the 50 years of ISPN history, MMC had a tremendous changes in its incidence, clinical management and outcome with advanced understanding of its pathogenesis. We reviewed the changes in MMC during the period.

METHODS

We reviewed the literature review and collected our experiences.

RESULTS

During the 50 years, major changes happened in many aspects of MMC including incidence, pathoembryogenesis, folate deficiency, prevention, prenatal diagnosis, mode of delivery, treatment policy with ethical considerations, clinical treatment including fetal surgery, latex allergy, retethering, management outcome, multidisciplinary team approach, and socioeconomic and family issues.

CONCLUSIONS

There was a great advance in the management and research of MMC during the 50 years. It is a monumental achievement of pediatric neurosurgeons and colleagues of the related fields.

The evolution of pediatric neurosurgery: reflection of personal experience of the last half-century

OBJECTIVES

In the past 50 years, pediatric neurosurgery has made tremendous strides, and gained its own identity as a distinct subspecialty. I have personally observed this progress and evolution in pediatric neurosurgery in multiple dimensions, which are described based upon my own experience and reflection.

METHODS

The development and evolutions of multiple domains of pediatric neurosurgery, including neuroimaging, hydrocephalus, pediatric brain tumor, spinal dysraphism, craniosynostosis, vascular malformation, functional neurosurgery and spinal disorders were reviewed and commented on based upon my own experience and reflection.

RESULTS

The field of pediatric neurosurgery has grown in all aspects of diagnosis and therapy owing to the introduction of computers, innovative techniques and technologies and new discoveries of scientific data including molecular investigations.

CONCLUSION

A minimally invasive approach and molecular target therapy are a current trend. The past half century's clinical experience and advances in biomedical knowledge and techniques provide foundation for further improvement in the care of children of the next generation. Prospective artificial intelligence will likely promote further advances in pediatric neurosurgery.

State of the Art Bowel Management for Pediatric Colorectal Problems: Spinal Anomalies

BACKGROUND

Patients with spinal abnormalities often struggle with fecal and/or urinary incontinence (up to 87 and 92%, respectively) and require a collaborative approach to bowel management in conjunction.

METHODS

To define existing approaches and propose state-of-the-art bowel management, a literature search was performed using Medline/PubMed, Google Scholar, Cochrane, and EMBASE databases and focusing on the manuscripts published July 2013 and July 2023.

RESULTS

Patients with spinal anomalies have impaired innervation of the rectum and anal canal, decreasing the success rate from laxatives and rectal enemas. Thus, transanal irrigations and antegrade flushes are widely utilized in this group of patients. Based on spinal MRI, the potential for bowel control in these children depends on age, type, and lesion level. On referral for bowel management, a contrast study is performed to assess colonic motility and evacuation of stool, followed by a series of abdominal X-rays to define colonic emptying and adjust the regimen. The options for management include laxatives, rectal enemas, transanal irrigations, antegrade flushes, and the creation of a stoma. Approximately 22-71% of patients achieve social continence dependent on the type and level of the lesion.

CONCLUSION

Patients with spinal anomalies require a thorough assessment for continence potential and stool burden prior to initiation of bowel management. The optimal treatment option is defined according to the patient's age, anatomy, and mobility. The likelihood of independent bowel regimen administration should be discussed with the patients and their caregivers.

Implementation and Assessment of a Laparotomy-Assisted Three-Port Fetoscopic Spina Bifida Repair Program

Open spina bifida (OSB) is a congenital, non-lethal malformation with multifactorial etiology. Fetal therapy can be offered under certain conditions to parents after accurate prenatal diagnostic and interdisciplinary counseling. Since the advent of prenatal OSB surgery, various modifications of the original surgical techniques have evolved, including laparotomy-assisted fetoscopic repair. After a two-year preparation time, the team at the University of Giessen and Marburg (UKGM) became the first center to provide a three-port, three-layer fetoscopic repair of OSB via a laparotomy-assisted approach in the German-speaking area. We point out that under the guidance of experienced centers and by intensive multidisciplinary preparation and training, a previously described and applied technique could be transferred to a different setting.

Morbidity and etiology-based success rate of combined endoscopic ventriculostomy and choroid plexus cauterization: a systematic review and meta-analysis of 1918 infants

Approaches to the treatment of infant hydrocephalus vary among centers. Standard shunting carries a significant infection rate, an unpredictable time-to-failure, and the life-long risk of recurrent failures. Combined choroid plexus cauterization (CPC) and endoscopic third ventriculostomy (ETV) have been increasingly employed over the past decade as an alternative approach in an attempt to avoid shunt dependency. We performed a systematic review and meta-analysis to explore the reported morbidity associated with ETV/CPC and its rate of success reported for specific etiologies of infant hydrocephalus. The protocol of this study was registered with the International prospective register of Systematic Reviews (PROSPERO) with the following registration number: CRD 42022343898. The study utilized four databases of medical literature to perform a systematic search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Several parameters were extracted from the included studies including authors, publication year, region, study design, sample size, mean age, success rate, complication rate, reported complications, hydrocephalus etiology, median time-to-failure, secondary management after failure, and mean follow-up time. The outcomes of interest, success, and complication rates were pooled using 95% confidence intervals (CI) and a random effects model. Heterogeneity was assessed using the I2 test. Twenty-eight studies met the inclusion criteria from an initial search result of 472 studies. The study included 1938 infants (1918 of which were included in the meta-analysis). The overall success rate of combined ETV/CPC is 0.59 (95% CI (0.53, 0.64), I2 = 82%). Etiology-based success rate is 0.71, 0.70, 0.64, and 0.52 for aqueductal stenosis, myelomeningocele, postinfectious hydrocephalus, and posthemorrhagic hydrocephalus, respectively. The overall complication rate is 0.04 (95% CI (0.02, 0.05), I2 = 14%). Our study presents a comprehensive analysis of the current evidence on the use of ETV/CPC for treating hydrocephalus in infants. The findings demonstrate the potential efficacy of this procedure; however, it is crucial to acknowledge the limitations inherent in the included studies, such as selection bias and limited follow-up, which could have impacted the reported outcomes.

Impairments and comorbidities in adults with cerebral palsy and spina bifida: a meta-analysis

Introduction

Aging with a childhood-onset disability, such as cerebral palsy (CP), spina bifida (SB), and muscular diseases (MD), comes along with significant impairments and comorbidities. Despite the increasing evidence an overall picture is lacking. This study aimed to review the literature about adults with CP/SB/MD and impairments and comorbidities to perform a meta-analysis.

Materials and methods

Embase, PubMed, Cinahl, and Google Scholar were searched (2000-2020). Search terms included adults with one of the aforementioned disabilities combined with impairments and comorbidities. If specific impairments or comorbidities were reported by at least four studies, these were included in the study. Pooled prevalence (95% Confidence Interval) of impairments/comorbidities were calculated.

Results

The search yielded 7,054 studies of which 95 were included in the meta-analysis (64 CP, 31 SB, 0 MD). In total estimates were calculated for 26 (CP) and 11 (SB) outcomes. In adults with CP, pain [56.4% (95%CI 48.8-63.8)], deformities [44.2% (95%CI 12.9-78.4)], intellectual disability [37.2% (95%CI 26.7-48.3)], and fatigue [36.9% (95%CI 24.6-50.1)] were most prevalent; renal disease [3.0% (95%CI 2.1-4.2)] and stroke/rheumatic diseases {4.8% (95%CI 3.4-6.5; 4.8% (95%CI 1.5-9.9)] respectively} were least prevalent. For adults with SB, bladder incontinence [60.0% (95%CI 50.5-69.2)], bowel incontinence [49.2% (95%CI 34.5-64.0)], pain [44.1% (95%CI 27.4-61.5)], and sleeping problems [30.3% (95%CI 4.7-65.8)] were most prevalent; diabetes [4.8% (95%CI 2.8-7.3)] and renal disease [8.7% (95%CI 2.0-19.9)] were least prevalent. The included studies showed large heterogeneity.

Conclusions

More research is needed to study health issues in adults with MD. Adults with CP or SB deal with a variety of health issues. More attention for the mental health of these adults is needed. There also is a need for accessible and adequate screening, preventive measures and clinical follow-up.

Identifying predictive factors for bowel control in patients with spina bifida and spinal cord injuries

PURPOSE

This study aimed to assess our bowel management program (BMP) and identify predictive factors for bowel control in patients with Spina Bifida (SB) and Spinal Cord Injuries (SCI). Additionally, in patients with SB, we examined the impact of fetal repair (FRG) on bowel control.

METHODS

We included all patients with SB and SCI seen in the Multidisciplinary Spinal Defects Clinic at Children's Hospital Colorado from 2020 to 2023.

RESULTS

336 patients included. Fecal incontinence was present in 70% and bowel control in 30%. All patients with urinary control also had bowel control. Fecal incontinence prevalence was higher in patients with ventriculoperitoneal (VP) shunt (84%), urinary incontinence (82%), and wheelchair users (79%) compared to those who did not need a VP shunt (56%), had urinary continence (0%) and non-wheelchair users (52%), respectively (p =  < 0.001 in all three scenarios). After completing BMP, 90% remained clean for stool. There was no statistical significance when comparing bowel control in FRG with non-fetal repair group.

CONCLUSIONS

Urinary continence predicts bowel control in patients with SB and SCI. Risk factors for fecal incontinence were the need for a VP shunt, urinary incontinence, and wheelchair usage. We did not find any positive impact of fetal repair on bowel and urinary control.

What has changed in pediatric neurosurgical care in spina bifida? A 30-year UAB/Children's of Alabama observational overview

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.

Education and employment as young adults living with spina bifida transition to adulthood in the USA: A study of the National Spina Bifida Patient Registry

AIM

To describe the education and employment transition experience of young adults with spina bifida (YASB) and investigate factors associated with employment.

METHOD

We queried education and employment data from the US National Spina Bifida Patient Registry from 2009 to 2019. We applied generalized estimating equations models to analyze sociodemographic and disease-related factors associated with employment.

RESULTS

A total of 1909 participants (850 males, 1059 females) aged 18 to 26 years contributed 4379 annual visits. Nearly 84% had myelomeningocele and, at last visit, the median age was 21 years (mean 21 years 5 months, SD 2 years 10 months). A total of 41.8% had at least some post-high school education, and 23.9% were employed. In a multivariable regression model, employment was significantly associated with education level, lower extremity functional level, bowel continence, insurance, and history of non-shunt surgery. This large, national sample of YASB demonstrated low rates of post-secondary education attainment and employment and several potentially modifiable factors associated with employment.

INTERPRETATION

Specific sociodemographic, medical, and functional factors associated with employment are important for clinicians to consider when facilitating transition for YASB into adulthood. Additional research is needed to understand the impact of cognitive functioning and social determinants of health on transition success in YASB.

WHAT THIS PAPER ADDS

There were low education attainment and employment rates in a large sample of young adults with spina bifida. Specific sociodemographic, medical, and functional factors are associated with employment. Some employment-associated factors, such as continence and self-management skills, are modifiable.

Outcomes of autologous bone marrow mononuclear cell administration in the treatment of neurologic sequelae in children with spina bifida

BACKGROUND

To evaluate the safety and efficacy of autologous bone marrow mononuclear cell (BMMNC) infusion in the management of neurological sequelae in children with spina bifida (SB).

METHODS

BMMNCs were harvested from bilateral anterior iliac crests. Two intrathecal BMMNC administrations were performed with an interval of 6 months. The measurements of outcomes included clinical assessments, cystomanometry and rectomanometry.

RESULTS

Eleven children with SB underwent autologous BMMNC infusions from 2016 to 2020. There were no severe adverse events during the study period. The number of patients requiring assistance to expel stools decreased from 11 before cell infusion to 3 after the second cell infusion. The number of patients who had urine leakage decreased from 9 patients at baseline to 3 patients after the second BMMNC infusion. The mean bladder capacity increased from 127.7 ± 59.2 ml at baseline to 136.3 ± 54.8 ml at six months and to 158.3 ± 56.2 ml at 12 months after BMMNC infusions. Detrusor pressure (pdet) decreased from 32.4 ± 22.0 cm H₂O at baseline to 21.9 ± 11.8 cm H₂O after 12 months of follow-up. At baseline, six patients could walk independently. After the 2nd infusion, eight patients could walk independently.

CONCLUSION

Intrathecal infusions of autologous bone marrow mononuclear cells are safe and may improve bowel, bladder, and motor function in children with SB.

Identification of Neurocan and Phosphacan as Early Biomarkers for Open Neural Tube Defects

Open neural tube defects (NTDs) such as myelomeningocele (MMC) are debilitating and the most common congenital defects of the central nervous system. Despite their apparent clinical importance, the existing early prenatal diagnostic options for these defects remain limited. Using a well-accepted retinoic-acid-induced model of MMC established in fetal rats, we discovered that neurocan and phosphacan, the secreted chondroitin sulfate proteoglycans of the developing nervous system, are released into the amniotic fluid (AF) of fetal rats displaying spinal cord defects. In contrast to normal controls, elevated AF levels of neurocan and phosphacan were detected in MMC fetuses early in gestation and continued to increase during MMC progression, reaching the highest level in near-term fetuses. The molecular forms of neurocan and phosphacan identified in the AF of MMC fetuses and those found in MMC spinal cords were qualitatively similar. In summary, this is the first report demonstrating the presence of neurocan and phosphacan in the AF of MMC fetuses. The identification of elevated levels of neurocan and phosphacan in the AF of MMC fetuses provides two prospective biomarkers with the potential for early prenatal diagnosis of open NTDs.

Advances in Fetal Surgical Repair of Open Spina Bifida

Spina bifida remains a common congenital anomaly of the central nervous system despite national fortification of foods with folic acid, with a prevalence of 2-4 per 10,000 live births. Prenatal screening for the early detection of this condition provides patients with the opportunity to consider various management options during pregnancy. Prenatal repair of open spina bifida, traditionally performed by the open maternal-fetal surgical approach through hysterotomy, has been shown to improve outcomes for the child, including decreased need for cerebrospinal fluid diversion surgery and improved lower neuromotor function. However, the open maternal-fetal surgical approach is associated with relatively increased risk for the patient and the overall pregnancy, as well as future pregnancies. Recent advances in minimally invasive prenatal repair of open spina bifida through fetoscopy have shown similar benefits for the child but relatively improved outcomes for the pregnant patient and future childbearing.

Intrauterine closure of myelomeningocele defects with primary linear repair versus bipedicle fasciocutaneous flaps: a post-MOMS cohort study with long-term follow-up

OBJECTIVE

The objective of this study was to determine the effects of in utero bipedicle flaps on maternal-fetal morbidity/mortality, the need for CSF diversion, and long-term functional outcomes.

METHODS

Eighty-six patients who underwent fetal myelomeningocele repair from 2011 to 2021 at a single institution were reviewed. Primary outcomes included intrauterine fetal demise, postnatal death, postnatal myelomeningocele repair dehiscence, and CSF diversion by final follow-up.

RESULTS

The cohorts were no different with regard to race, ethnicity, maternal age at fetal surgery, body mass index, gravidity, parity, gestational age at fetal surgery, estimated fetal weight at fetal surgery, or fetal lesion level. Of the 86 patients, 64 underwent primary linear repair and 22 underwent bipedicle flap repair. There were no significant differences in rates of intrauterine fetal demise, postnatal mortality, midline repair site dehiscence, or the need for CSF diversion by final follow-up. Operative times were longer (32.5 vs 18.7 minutes, p < 0.001) and gestational age at delivery was lower (232 vs 241 days, p = 0.01) in the bipedicle flap cohort, but long-term functional outcomes were not different.

CONCLUSIONS

Analysis of the total cohort affirms the long-term benefits of fetal myelomeningocele repair. In utero bipedicle flaps are safe and can be used for high-tension lesions without increasing perioperative risks to the mother or fetus. In utero flaps preserve the long-term benefits seen with primary linear repair and may expand inclusion criteria for fetal repair, providing life-changing care for more patients.

Causes of death among people with myelomeningocele: A multi-institutional 47-year retrospective study

PURPOSE

This study aimed to analyze organ system-based causes and non-organ system-based mechanisms of death (COD, MOD) in people with myelomeningocele (MMC), comparing urological to other COD.

METHODS

A retrospective review was performed of 16 institutions in Canada/United States of non-random convenience sample of people with MMC (born > = 1972) using non-parametric statistics.

RESULTS

Of 293 deaths (89% shunted hydrocephalus), 12% occurred in infancy, 35% in childhood, and 53% in adulthood (documented COD: 74%). For 261 shunted individuals, leading COD were neurological (21%) and pulmonary (17%), and leading MOD were infections (34%, including shunt infections: 4%) and non-infectious shunt malfunctions (14%). For 32 unshunted individuals, leading COD were pulmonary (34%) and cardiovascular (13%), and leading MOD were infections (38%) and non-infectious pulmonary (16%). COD and MOD varied by shunt status and age (p < = 0.04), not ambulation or birthyear (p > = 0.16). Urology-related deaths (urosepsis, renal failure, hematuria, bladder perforation/cancer: 10%) were more likely in females (p = 0.01), independent of age, shunt, or ambulatory status (p > = 0.40). COD/MOD were independent of bladder augmentation (p = >0.11). Unexplained deaths while asleep (4%) were independent of age, shunt status, and epilepsy (p >= 0.47).

CONCLUSION

COD varied by shunt status. Leading MOD were infectious. Urology-related deaths (10%) were independent of shunt status; 26% of COD were unknown. Life-long multidisciplinary care and accurate mortality documentation are needed.

Effect of preoperative low-normal cervical length on perinatal outcome after laparotomy-assisted fetoscopic spina bifida repair

OBJECTIVE

To determine if preoperative cervical length in the low-normal range increases the risk of adverse perinatal outcome in patients undergoing fetoscopic spina bifida repair.

METHODS

This was a retrospective cohort study of patients who underwent fetal spina bifida repair between September 2014 and May 2022 at a single center. Cervical length was measured on transvaginal ultrasound during the week before surgery. Eligibility for laparotomy-assisted fetoscopic spina bifida repair was as per the criteria of the Management of Myelomeningocele Study, although maternal body mass index (BMI) up to 40 kg/m² was allowed. Laparotomy-assisted fetoscopic spina bifida repair was performed, with carbon dioxide insufflation via two 12-French ports in the exteriorized uterus. All patients received the same peri- and postoperative tocolysis regimen, including magnesium sulfate, nifedipine and indomethacin. Postoperative follow-up ultrasound scans were performed either weekly (< 32 weeks' gestation) or twice a week (≥ 32 weeks). Perinatal outcome was compared between patients with a preoperative cervical length of 25-30 mm vs those with a cervical length > 30 mm. Logistic regression analyses and generalized linear mixed regression analyses were used to predict delivery at less than 30, 34 and 37 weeks' gestation.

RESULTS

The study included 99 patients with a preoperative cervical length > 30 mm and 12 patients with a cervix 25-30 mm in length. One further case which underwent spina bifida repair was excluded because cervical length was measured > 1 week before surgery. No differences in maternal demographics, gestational age (GA) at surgery, duration of surgery or duration of carbon dioxide uterine insufflation were observed between groups. Cases with low-normal cervical length had an earlier GA at delivery (median (range), 35.2 (25.1-39.7) weeks vs 38.2 (26.0-40.9) weeks; P = 0.01), higher rates of delivery at < 34 weeks (41.7% vs 10.2%; P = 0.01) and < 30 weeks (25.0% vs 1.0%; P < 0.01) and a higher rate of preterm prelabor rupture of membranes (PPROM) (58.3% vs 26.3%; P = 0.04) at an earlier GA (mean ± SD, 29.3 ± 4.0 weeks vs 33.0 ± 2.4 weeks; P = 0.05) compared to those with a normal cervical length. Neonates of cases with low-normal cervical length had a longer stay in the neonatal intensive care unit (20 (7-162) days vs 9 (3-253) days; P = 0.02) and higher rates of respiratory distress syndrome (50.0% vs 14.4%; P < 0.01), sepsis (16.7% vs 1.0%; P = 0.03), necrotizing enterocolitis (16.7% vs 0%; P = 0.01) and retinopathy (33.3% vs 1.0%; P < 0.01). There was an association between preoperative cervical length and risk of delivery at < 30 weeks which was significant only for patients with a maternal BMI < 25 kg/m² (odds ratio, 0.37 (95% CI, 0.07-0.81); P = 0.02).

CONCLUSIONS

Low-normal cervical length (25-30 mm) as measured before in-utero laparotomy-assisted fetoscopic spina bifida repair may increase the risk of adverse perinatal outcomes, including PPROM and preterm birth, leading to higher rates of neonatal complications. These data warrant further research and are of critical relevance for clinical teams considering the eligibility of patients for in-utero spina bifida repair. Based on this evidence, patients with a low-normal cervical length should be aware of their increased risk for adverse perinatal outcome. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

2023 updates to the spina bifida transition to adult care guidelines

PURPOSE

This article provides an update to the 2018 Spina Bifida Association's Transition to Adult Care Guidelines.

METHODS

A workgroup of topic experts was convened including authors from the initial guideline workgroup. The workgroup reviewed and updated the primary, secondary, and tertiary outcome goals, clinical questions, and guideline recommendations based on a literature review.

RESULTS

Twenty-two additional articles were identified from the literature search. Updated references included observational studies describing transition to adult care outcomes, transition care model initiatives, and a validated self-management assessment tool.

CONCLUSION

Structured transition initiatives increase the likelihood of establishing with adult care, decrease acute care use for young adults with spina bifida, and have the potential to improve quality of life and optimize chronic condition management. However, there is still a need to implement structure transition practices more broadly for this population using these recommended guidelines.

Age-based risk of end-stage kidney disease in patients with myelomeningocele

OBJECTIVE

We aimed to quantify end-stage kidney disease (ESKD) risk after infancy in individuals with myelomeningocele (MMC) followed by urology in the modern medical era and to assess if ESKD risk was higher after surgery related to a hostile bladder.

METHODS

We retrospectively reviewed patients with MMC followed by urology at our institution born ≥ 1972 (when clean intermittent catheterization was introduced) past 1 year of age (when mortality is highest, sometimes before establishing urology care). ESKD was defined as requiring permanent peritoneal/hemodialysis or renal transplantation. Early surgery related to hostile bladder included incontinent vesicostomy, bladder augmentation, detrusor Botulinum A toxin injection, ureteral reimplantation, or nephrectomy for recurrent urinary tract infections. Survival analysis and proportional hazards regression were used. Sensitivity analyses included: risk factor analysis with only vesicostomy, timing of surgery, including the entire population without minimal follow-up (n = 1054) and only patients with ≥ 5 years of follow-up (n = 925).

RESULTS

Overall, 1029 patients with MMC were followed for a median of 17.0 years (49% female, 76% shunted). Seven patients (0.7%) developed ESKD at a median 24.3 years old (5 hemodialysis, 1 peritoneal dialysis, 1 transplantation). On survival analysis, the ESKD risk was 0.3% at 20 years old and 2.1% at 30 years old (Figure). This was ∼100 times higher than the general population (0.003% by 21 years old, p < 0.001). Patients who underwent early surgery for hostile bladder had higher ESKD risk (HR 8.3, p = 0.001, 6% vs. 1.5% at 30 years). On exploratory analyses, gender, birth year, shunt status and wheelchair use were not associated with ESKD risk (p ≥ 0.16). Thirty-year ESKD risk was 10% after early vesicostomy vs. 1.4% among children without one (p = 0.001). Children undergoing bladder surgery between 1.5 and 5 years old had a higher risk of ESKD. No other statistically/clinically significant differences were noted.

COMMENT

Patients with MMC remain at risk of progressive renal damage throughout life. We relied on the final binary ESKD outcome to quantify this risk, rather than imprecise glomerular filtration rate formulas. Analysis was limited by few people developing ESKD, inconsistent documentation of early urodynamic findings and indications for bladder-related surgery.

CONCLUSIONS

While ESKD is relatively uncommon in the MMC population receiving routine urological care, affecting 2.1% of individuals in the first 3 decades, it is significantly higher than the general population. Children with poor bladder function are likely at high risk, underlining the need for routine urological care, particularly in adulthood.

Solo and Partnered Sexual Behavior Among an International Sample of Adults With Spina Bifida

BACKGROUND

Spina bifida (SB) may differentially impact adults' participation in solo and partnered sexual behaviors, but little research investigates this topic.

AIM

Describe solo and partnered sexual behaviors among an international sample of adult men and women with SB.

MAIN OUTCOME MEASURES

Ever participated (no/yes) and recent participation (>1 year ago/within last year) in solo masturbation, cuddled with a partner, held hands with a partner, kissed a partner, touched a partner's genital, had genitals touched by a partner, gave a partner oral sex, received oral sex from a partner, vaginal sex, anal sex, and sex toy use.

METHODS

Data were drawn from a larger cross-sectional, internet-based survey assessing the sexual behaviors of an international sample of men and women with SB. We used logistic regression to examine the impact of background (gender, age, independent living, and relationship status) and health (shunt status, ambulation, and genital sensation) factors on each outcome.

RESULTS

The sample consisted of 345 respondents aged 18-73 years from 26 nations. Very few (<3%) had no lifetime experience with any solo or partnered behaviors; 25.0% reported participating in all behaviors at some point in their lives. The median number of past year sexual behaviors (of 16 total) was 7. Lifetime and recent participation were associated with demographic and health factors.

CLINICAL IMPLICATIONS

Despite impairment, adults with spina bifida do participate in solo and partnered sexual behaviors. Medical personnel who work with this population should include discussions about sexuality as part of routine care.

STRENGTHS & LIMITATIONS

Although this research measured solo and partnered sexual behavior in large international sample of adults with spina bifida, it is limited by its cross-sectional retrospective design and non-clinical convenience sample.

CONCLUSION

Despite disability, many adults with SB participate in solo and partnered sexual behavior. Medical and psychosocial supports are needed to help adults in this population enjoy sexuality in a healthy and safe manner. Hensel DJ, Misseri R, Wiener JS, et al. Solo and Partnered Sexual Behavior Among an International Sample of Adults With Spina Bifida. J Sex Med 2022;19:1766-1777.

Characterizing syringomyelia and its clinical significance in 140 patients with lipomyelomeningocele

OBJECTIVE

The aims of this study were to characterize syringomyelia in patients with lipomyelomeningocele (LMMC) and investigate the association between the presence of a syrinx and patient neurological deficits.

METHODS

Patients with LMMC who had been admitted between 2007 and 2020 were included in the study. Syringomyelia on magnetic resonance imaging (MRI) was classified into three groups: true syrinx, early syrinx, and presyrinx. The correlation of clinical deficits (at birth, new onset, and progressive) and type of lipoma with the presence and type of syrinx was studied.

RESULTS

Among a total of 140 patients, the median age was 2.5 (IQR 1.3-9) years. Neurological deficits were present at birth in 75 (53.6%) patients, but 67 (47.9%) had new-onset deficits or progression of their birth deficits. The most common type of spinal lipoma was the transitional type (75.7%). Thirty-nine (27.9%) patients had a syrinx (37 with a true syrinx, 2 with an early syrinx), and 25 (17.9%) patients had a presyrinx. There was no significant correlation between the presence of a syrinx and patient neurological deficits. However, patients with a syrinx that was not adjacent to the lipoma (≥ 1 vertebral level away) had a higher incidence of deficits at birth (p = 0.045), whereas those with a syrinx spanning ≥ 5 vertebral levels had a higher incidence of progressive neurological deficits (p = 0.04). Six (75%) of 8 patients in whom serial MRI had shown syrinx progression had clinical worsening.

CONCLUSIONS

Syrinx location with respect to the spinal lipoma, syrinx length, and progressive syringomyelia may have clinical significance in patients with LMMC.

Multidisciplinary spina bifida clinic: the Chicago experience

Open spina bifida (open SB) is the most complex congenital abnormality of the central nervous system compatible with long-term survival. Multidisciplinary care is required to address the effect of this disease on the neurological, musculoskeletal, genitourinary, and gastrointestinal systems, as well as the complex psychosocial impact on the developing child. Individuals with SB benefit from the involvement of neurosurgeons, orthopedic surgeons, urologists, physical medicine and rehabilitation specialists, pediatricians, psychologists, physical/occupational/speech therapists, social workers, nurse coordinators, and other personnel. Multidisciplinary clinics are the gold standard for coordinated, optimal medical and surgical care. Ann and Robert H. Lurie Children's Hospital, formerly known as Children's Memorial Hospital, was one of the first hospitals in the USA to manage patients with this complex disease in a multidisciplinary manner. We describe the longitudinal experience of the multidisciplinary Spina Bifida Center at our institution and highlight the advances that have arisen from this care model over time. This clinic serves as an exemplar of organized, effective, and patient-centered approach to the comprehensive care of people living with open SB.

Racial and Ethnic Inequities in Use of Preventive Services Among Privately Insured Adults With a Pediatric-Onset Disability

PURPOSE

Cerebral palsy (CP) and spina bifida (SB) are pediatric-onset disabilities. Adults living with CP/SB are in a greater need of preventive care than the general population due to their increased risk for chronic diseases. Our objective was to compare White/Black and White/Hispanic inequities in the use of preventive services.

METHODS

Using 2007-2017 private claims data, we identified a total of 11,635 adults with CP/BS. Of these, 8,935 were White, 1,457 Black, and 1,243 Hispanic. We matched health-related variables (age, sex, comorbid conditions) between White adults and those in each minority subpopulation. Generalized estimating equations were used and all models were adjusted for age, sex, comorbidities, income, education, and US Census divisions. Outcomes of interest were: (1) any office visit; (2) any physical/occupational therapy; (3) wellness visit; (4) bone density screening; (5) cholesterol screening; and (6) diabetes screening.

RESULTS

The rate of recommended services for all subpopulations of adults with CP/SB was low. Compared with White adults, Hispanic adults had lower odds of wellness visits (odds ratio [OR] = 0.71, 95% CI, 0.53-0.96) but higher odds of diabetes screening (OR = 1.48, 95% CI, 1.13-1.93). Compared with White adults, Black adults had lower odds of wellness visits (OR = 0.50, 95% CI, 0.24-1.00) and bone density screening (OR = 0.54, 95% CI, 0.31-0.95).

CONCLUSIONS

Preventive service use among adults with CP/SB was low. Large White-minority disparities in wellness visits were observed. Interventions to address physical accessibility, adoption of telehealth, and increased clinician education may mitigate these disparities, particularly if initiatives target minority populations.

Pressure injuries are common in children with myelomeningocele: Results from a follow-up programme and register

AIM

To investigate the occurrence of pressure injuries (PIs) in children with myelomeningocele (MMC) and to investigate the association between PIs and orthoses use by disability-specific variables.

METHODS

Population-based registry study including participants in the Swedish multidisciplinary follow-up programme for MMC. Risks of PIs were investigated by birth cohort, country of birth, sex, type of MMC, muscle function level (MFL), and continence status.

RESULTS

Of 180 participants, 29% had PIs recorded. Of the 132 participants with >1 assessment records, 17.4% reported multiple PI occasions. More assessments increased the likelihood of PIs (Odds Ratio [OR] = 1.33, 95% CI 1.15-1.54) and participants born 2015-2018 had a lower OR of PIs than those born 2007-2010 (OR = 0.08, 95% CI = 0.01-0.74). Those at MFL I had lower OR of PIs than those at MFL V (OR = 0.06, 95% CI 0.01-0.64). Of the 73 participants with orthoses on the lower extremities, 47% reported skin irritations/injuries in the last 4 weeks; 30% reported that it made them stop using orthoses.

CONCLUSION

Pressure injuries are common even in young children with MMC. Many have recurring skin irritations. Inspecting for PIs should be part of a daily routine and tools to increase compliance are needed.

Factors Associated With Ambulation and Transfer Ability: A Study From the National Spina Bifida Patient Registry

OBJECTIVES

This study used a spina bifida electronic medical record and the National Spina Bifida Patient Registry to explore the relationship between neurosurgical/orthopedic surgeries and other variables on ambulation and transfer ability over time in individuals with spina bifida.

DESIGN

This study was an analysis of longitudinal data collected within the National Spina Bifida Patient Registry and spina bifida electronic medical record. Logistic regression models were used to determine which variables were associated with ambulation/transfer ability in the myelomeningocele (MMC) and non-MMC populations.

RESULTS

Longitudinal data from 806 individuals were collected. In the MMC group, decreased ambulation ability was associated with higher motor levels, tethered cord releases, spine/scoliosis surgeries, hip orthopedic surgeries, and having supplemental insurance. Increased ambulatory ability was associated with lower motor levels, tibial torsion/related surgeries, ankle/foot surgeries, being female, and being non-Hispanic/Latinx. Decreased transfer ability was associated with being Hispanic/Latinx and having higher motor levels. Lower motor level and ankle/foot surgeries were associated with increased transfer ability. No significant associations were found in the non-MMC group.

CONCLUSIONS

Motor level is an important predictor of ambulation and transfer ability in MMC. Surgeries distal to the knee were associated with higher levels of function; surgeries proximal to the knee were associated with lower functional levels.

Myelomeningocele Including Fetal Prescription

Myelomeningocele (MMC) is one of the most common birth defects, affecting 0.2 to 0.4 per 1,000 live births in the United States. The most strongly associated risk factor is low folate level in pregnancy. For this reason, 0.4- to 1.0-mg supplementation with folic acid is recommended in all pregnancies, and high-risk pregnancies are recommended to supplement with 4.0 mg of folic acid daily. The mechanism behind the development of MMC is believed to be failure of the caudal end of the neural tube to close during primary neurulation. Screening for MMC is achieved by using α-fetoprotein levels in maternal serum or amniocentesis in the first and second trimesters of pregnancy. Ultrasonography and fetal magnetic resonance imaging are used to confirm the presence of MMC as well as the location and size of the defect. Based on the results of the Management of Myelomeningocele Study, fetal repair is performed between 23 weeks and 25 weeks and 6 days of gestational age for appropriate candidates. Postnatal repair is more common and is performed 24 to 72 hours after birth. In general, patients with lesions at lower anatomical levels have a better prognosis. Most children with MMC will have neurogenic bladder and bowel dysfunction that affect the patient's and the caregiver's quality of life. Patients with higher levels of mobility, better familial support, and higher economic status report improved quality of life compared with other patients with MMC.

Spina Bifida: A Review of the Genetics, Pathophysiology and Emerging Cellular Therapies

Spina bifida is the most common congenital defect of the central nervous system which can portend lifelong disability to those afflicted. While the complete underpinnings of this disease are yet to be fully understood, there have been great advances in the genetic and molecular underpinnings of this disease. Moreover, the treatment for spina bifida has made great advancements, from surgical closure of the defect after birth to the now state-of-the-art intrauterine repair. This review will touch upon the genetics, embryology, and pathophysiology and conclude with a discussion on current therapy, as well as the first FDA-approved clinical trial utilizing stem cells as treatment for spina bifida.

Caregiver reports of physician risk counseling for adolescents with special health care needs

BACKGROUND

Research has indicated disagreement between physicians, caregivers, and adolescents with special health care needs regarding appropriate risk counseling.

OBJECTIVE

The study examines caregivers' perceptions of adolescent risk counseling. We hypothesize caregivers of adolescents with special healthcare needs will perceive a lower rate of risk counseling.

METHODS

Data come from the 2016 National Survey of Children's Health. The sample included 13,542 adolescents. Analysis completed using logistic regression with odds ratios.

RESULTS

The results indicate no difference in caregiver perceptions of risk counseling for adolescents with special healthcare needs. Gender, race/ethnicity, and relationship between caregiver and provider influenced perception of receipt of risk counseling, regardless of health status.

CONCLUSIONS

Although adolescents with special healthcare needs perceive their risk behavior counseling to be lacking in quantity/quality, caregivers perceive such counseling does occur. These results highlight the need for comprehensive risk counseling for groups at risk of known health disparities.

PRACTICE IMPLICATIONS

Physicians and providers should be provided with the training and resources needed to be comfortable to engage in risk counseling. Adolescents need the opportunity to see their provider privately, and education to advocate for information risky behaviors. Parents, providers, and adolescents should be included in future risk counseling intervention plans.

Financial toxicity among individuals with spina bifida and their families: A qualitative study and conceptual model

INTRODUCTION

Spina bifida is the most common permanently disabling birth defect in the United States and requires lifelong, multi-specialty care. The cost of such care has the potential to result in financial toxicity - the 'objective financial burden' and 'subjective financial distress' which can negatively impact clinical outcomes. While this concept has been extensively studied in other areas of medicine, particularly oncology, financial toxicity has not yet been examined in pediatric urology or in individuals with spina bifida and their families/caregivers.

OBJECTIVE

To qualitatively explore the presence of financial toxicity in individuals with spina bifida and their caregivers with the objective of identifying themes and creating a conceptual model.

MATERIALS AND METHODS

We conducted semi-structured interviews with individuals with spina bifida and/or their caregivers with the aim of eliciting information regarding financial distress associated with spina bifida care. Interviews were transcribed and qualitative thematic analysis was performed to identify recurring themes. These insights were used to create a conceptual model of financial toxicity among individuals with spina bifida.

RESULTS

A total of 14 interviews were conducted (total of 6 patients and 13 parents/caregivers). Average patient age was 17.9 years. Five dominant themes were identified: 1) resources (insurance type, community support, etc.), 2) direct costs (copays, deductibles, travel expenses, etc.), 3) indirect costs (lost work time, hindered career advancement, resource navigation burden, etc.), 4) coping (work adjustments, decreased spending, etc.), and 5) affect (lack of control, uncertainty, worry, etc.). These insights were used to create a conceptual model.

DISCUSSION

This is the first study to explore financial toxicity in spina bifida and establish a conceptual model. Our findings are corroborated by prior spina bifida literature and are closely mirrored by studies in cancer patients. Given that financial toxicity is associated with negative outcomes in other medical domains, the impact of financial toxicity on health outcomes among individuals with spina bifida warrants further study, particularly in instrument development to better understand and quantify financial toxicity in this group.

CONCLUSION

Financial toxicity is a concern among individuals with spina bifida and their caregivers. This concept will need to be investigated further in order to develop validated measurement tools, identify solutions, and provide optimal care; our conceptual model will help guide these future investigations.

What is the Role of Scoliosis Surgery in Adolescents and Adults with Myelomeningocele? A Systematic Review

BACKGROUND

Life expectancy of individuals with spina bifida has continued to improve over the past several decades. However, little is known about the longitudinal course of scoliosis in individuals with myelomeningocele (MMC), a spina bifida subtype, across their lifespan. Specifically, it is not known whether management during or after the transition years from adolescence to adulthood is associated with comorbidities in adulthood nor if these individuals benefit from scoliosis treatment later in life.

QUESTIONS/PURPOSES

In this systematic review, we asked: (1) Is the risk of secondary impairments (such as bladder or bowel incontinence, decreased ambulation, and skin pressure injuries) higher among adolescents and adults with MMC and scoliosis than among those with MMC without scoliosis? (2) Is there evidence that surgical management of scoliosis is associated with improved functional outcomes in adolescents and adults with MMC? (3) Is surgical management of scoliosis associated with improved quality of life in adolescents and adults with MMC?

METHODS

We performed a systematic review of articles in Medline and Embase from 2000 until February 5, 2021. Search terms such as "spinal dysraphism," "spina bifida," "meningomyelocele," and "scoliosis" were applied in diverse combinations. A total of 1429 publications were identified, and 13 were eligible for inclusion. We included original studies reporting on scoliosis among individuals older than 15 years with MMC. When available, we extracted the prevalence of MMC and scoliosis, studied population age, percentage of patients experiencing complications, functional outcomes, and overall physical function. We excluded non-English articles and those with fewer than 10 individuals with scoliosis and MMC. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses, and registered the review before data collection (PROSPERO: CRD42021236357). We conducted a quality assessment using the Methodologic Index for Nonrandomized Studies (MINORS) tool. In 13 included studies, there were 556 individuals with MMC and scoliosis. Most were retrospective case series, although a minority were retrospective/comparative studies. The mean MINORS score was 12.3 ± 1.65 (a MINORS score over 12 generally is considered good reporting quality, scores below 12 are considered at high risk of bias).

RESULTS

In general, studies found that individuals with MMC and scoliosis were more likely to have secondary impairments such as bladder/bowel incontinence, decreased ambulation, and pressure injuries than were patients with MMC without scoliosis. These secondary impairments were associated with hydrocephalus and high-level MMC lesions. However, when one study evaluated mortality, the results showed that although most deceased individuals who had spina bifida had scoliosis, no association was found between the age of death and scoliosis. Among the studies evaluating functional outcomes, none supported strong functional improvement in individuals with MMC after surgery for scoliosis. No correlation between the Cobb angle and sitting balance was noted; however, the degree of pelvic obliquity and the level of motor dysfunction showed a strong correlation with scoliosis severity. There was no change in sitting pressure distributions after spinal surgery. The lesion level and scoliosis degree independently contributed to the degree of lung function impairment. Although studies reported success in correcting coronal deformity and stopping curve progression, they found no clear benefit of surgery on health-related quality of life and long-term outcomes. These studies demonstrated that the level of neurologic function, severity of hydrocephalus, and brainstem dysfunction are greater determinants of quality of life than spinal deformity.

CONCLUSION

This systematic review found that adolescents and adults with MMC and scoliosis are more likely to have secondary impairments than their peers with MMC only. The best-available evidence does not support strong functional improvement or health-related quality of life enhancement after scoliosis surgery in adolescents and adults with MMC. The level of neurologic dysfunction, hydrocephalus, and brainstem dysfunction are greater determinants of quality of life. Future prospective studies should be designed to answer which individuals with MMC and scoliosis would benefit from spinal surgery. Our findings suggest that the very modest apparent benefits of surgery should cause surgeons to approach surgical recommendations in this patient population with great caution, and surgeons should counsel patients and their families that the risk of complications is high and the benefits may be small.

LEVEL OF EVIDENCE

Level IV, therapeutic study.

The Transition from Pediatric to Adult Health Care in Young Adults with Spina Bifida: Demographic and Physician-Related Correlates

OBJECTIVE

This study examined the transition to adult health care for individuals with spina bifida (SB) and explored demographic and relational associations with transition status.

METHOD

Young adults with SB (18-30; n = 326) were recruited to complete an anonymous, online survey. Frequencies of reported experiences, behaviors, and satisfaction with the transition to adult health care were examined. Nonparametric tests and exploratory hierarchical regressions were used to examine demographic and relational factors with physicians between those (1) who had and had not yet transitioned and (2) who did and did not return to pediatric care.

RESULTS

Most of the sample reported having transitioned to adult health care, with three-quarters reporting that their primary physician is an adult primary care doctor. Individuals who had transitioned were more likely to be younger (p = 0.01) and to not have a shunt (p = 0.003). Beyond the effect of age and shunt status, relational factors with pediatric providers were not associated with transition (p > 0.1). After transition, over one-third reported returning to a pediatric provider. Those who did not return to pediatric care were more likely to have myelomeningocele, be a full-time student, and to not have a shunt (p < 0.001). Beyond the effect of age and shunt status, lower ratings of communication with adult providers were associated with a return to pediatric care (p = 0.04).

CONCLUSION

The results highlight the need for additional research about barriers and facilitators to the transition to adult health care to target interventions that support this critical milestone in young adults with SB.

Quality of life in a 61-year-old paraplegic patient with myelomeningocele: illustrative case

BACKGROUND

Limited data exist on survival of patients with myelomeningocele (MM) into late adulthood. Patients born prior to 1975 received less surgical treatment and demonstrated poorer survival. Patients born after 1975 show lower mortality rates because of advancements in prenatal care, diagnostics, technology, and treatment. The increasing number of adult patients with MM demonstrates these successes but also highlights the need for a better understanding of both medical management and quality-of-life issues in this population.

OBSERVATIONS

A 61-year-old woman presented to the hospital with a functional level T12, vertebral level low lumbar MM that had developed a tissue defect with a cerebrospinal fluid leak. The patient had her MM closed at birth and since then had received no additional surgical treatment or repair of her MM defect. After successful treatment, the patient continues to follow up for additional decompression procedures and admits to a good quality of life.

LESSONS

This case adds to the limited literature describing management of patients with MM over the age of 60. The patient’s self-described good quality of life and longevity align with reports of importance of independence, level of education, bowel management, ability to provide self-care, strong interpersonal relationships, and absence of shunted hydrocephalus.

Sociodemographic disparities as a determinant of fetal versus postnatal surgical myelomeningocele repair

OBJECTIVE

Relatively few women undergo open maternal-fetal surgery (OMFS) for myelomeningocele (MMC) despite the potential to reverse hindbrain herniation, reduce the rate of infant shunt-dependent hydrocephalus, and improve ambulation. These benefits have the potential to significantly reduce morbidity and lifetime medical care. In this study, the authors examined demographics and socioeconomic variables of women who were offered and opted for OMFS for MMC versus postnatal MMC surgery, with the purpose of identifying variables driving the disparity between these two patient populations.

METHODS

This was a retrospective case-control study of patients who underwent evaluation for OMFS for MMC at a single academic hospital from 2015 to 2020. Race/ethnicity, primary insurance type, zip code, and BMI were collected and compared by treatment received and eligibility status for OMFS. Prevalence odds ratios were used to test for associations between each independent variable and the two outcomes. Logistical regression models were utilized to determine significant predictors of undergoing OMFS and being eligible for OMFS.

RESULTS

Of 96 women, 36 underwent OMFS for MMC, 40 received postnatal repair, and 20 either terminated the pregnancy or received care at another institution. Overall, 66 (68.8%) women were White, 14 (14.6%) were Black, 13 (13.5%) were Hispanic/Latinx, 1 (1.0%) was Asian, and 2 (2.1%) identified as other or multiple races. Among women who underwent OMFS for MMC, 27 (75.0%) were White, 2 (5.6%) were Black, 4 (11.1%) were Hispanic/Latinx, 1 (2.8%) was Asian, and 2 (5.6%) identified as other or multiple races. Having private insurance or TRICARE was associated with higher odds of being eligible for OMFS compared with women who were uninsured or had Medicaid when accounting for race and income (OR 3.87, 95% CI 1.51-9.59).

CONCLUSIONS

The population evaluated and treated for MMC was homogeneous and insufficiently representative of the population affected by the disease. This finding raises concern, as it suggests underlying barriers to formal evaluation for OMFS for MMC. Insurance status and BMI have a significant association between the access to and election of OMFS, revealing socioeconomic disparities. This was the first study to explore sociodemographic characteristics of patient populations who may be at risk for limited access to highly specialized fetal surgical care.

Team Approach: The Management of Adolescents and Adults with Scoliosis and Spina Bifida

»

Globally, the prevalence of myelomeningocele, the most common subtype of spina bifida, is 0.2 to 6.5 per 1,000 live births. In the U.S., adults account for >67% of the overall population with spina bifida.

»

With an estimated prevalence of up to 50%, scoliosis is one of the most common and severe orthopaedic conditions in patients with myelomeningocele.

»

The variable effects that scoliosis can have on an individual, the comorbidities associated with progressive scoliosis, and the risks associated with spine surgery call for a strong partnership and care coordination between medical and surgical teams to deliver a patient-centered approach.

»

A coordinated, structured, planned, and incremental team approach can help individuals achieve the overall goals of functionality and independence, as well as successful transition to adulthood.

»

Teams should consider a patient's social determinants of health (e.g., poverty or language barriers) and the effect of scoliosis on quality of life before proceeding with spinal deformity correction.

Acquired and congenital spinal cord injury is associated with lower likelihood of PSA screening

PURPOSE

Studies have demonstrated lower prevalence of prostate cancer among patients with spinal cord injury but more advanced stage at diagnosis. However, there is a lack of literature on prostate cancer screening among these patients. We sought to evaluate prostate cancer screening occurrence in patients with spinal cord injury at our institution compared to a matched, unaffected population.

METHODS

We conducted a retrospective review of patients with the criteria: male, age 50-70, and diagnosis of cerebral palsy, spina bifida, or quadriplegia. A control cohort was matched by age, race, insurance, and co-morbidities. PSA screening, PSA value, prostate MRI, prostate biopsy, and biopsy outcome were compared. Multivariate logistic regression analysis was performed to determine the association between patient variables and PSA screening.

RESULTS

The study cohort and control cohort included 2180 patients each. Patients with spinal cord injury had significantly lower rates of PSA screening (15% vs 24%, p < 0.00001), MRI (0.1% vs 0.6%, p = 0.02), and biopsy (0.6% vs 1.3%, p = 0.01) compared to control. Spinal cord injury was associated with a lower likelihood of PSA screening (OR = 0.56, CI = 0.48 - 0.65, p < 0.00001). There were no significant differences in PSA value and biopsy outcomes.

CONCLUSION

Patients with spinal cord injury had a lower likelihood of PSA screening compared to a matched control population. Since PSA screening is a shared-decision making process, providers should consider the increasing life expectancy of patients with spinal cord injury and risks of under-testing for prostate cancer.

Exploratory study of the provision of academic and health-related accommodations to transition-age adolescents and emerging adults with spina bifida

PURPOSE

The purpose of this exploratory study was to investigate the types of academic and health-related accommodations provided to adolescents and emerging adults with spina bifida aged 9-20 years.

METHODS

Data were extracted from the paper and electronic records of transition-age youth enrolled in the study. Four open ended items involved content analysis.

RESULTS

The most frequently identified accommodation was enrollment in special education classes in 47.7% of the charts. Other academic accommodations that were most often reported were adaptive physical education (n = 71, 39.9%), tutoring (n = 28; 15.7%), and home schooling (n = 21; 11.8%). Clean intermittent catheterization was the most frequently identified health-related accommodation provided by the school nurse/aide (n = 57; 32%).The largest percentage of requests for additional accommodations were made during the middle school grades (15; 54.8%) followed by high school (10; 32.2%).

CONCLUSION

Findings demonstrated that persistent issues were identified by parents/adolescents regarding the provision of school-related accommodations. This is a relevant area for clinical practice to ensure students with special health care needs and those with spina bifida receive the academic and health-related accommodations in their Individualized Education Program/504 plans.

Minimum 5-year follow-up outcomes for one-stage posterior instrumentation without neurosurgery intervention for correction of scoliosis associated with Chiari I malformation and syringomyelia

INTRODUCTION

Traditionally, the common belief has been that, all patients with Chiari I malformation (CM-1) and syringomyelia (SM) undergoing a neurosurgical procedure even if they are neurologically asymptomatic. As the pathology of CM-1 and SM has become better understood, the traditional concepts have been challenged. The objective of this study was to investigate the minimum 5-year follow-up clinical outcomes of surgical treatment of patients with scoliosis associated with CM-1 and SM and to evaluate the necessity of neurosurgical intervention before corrective surgery.

METHODS

This retrospective study was performed from May 2009 to September 2014. We enrolled 35 patients with scoliosis associated with CM-1 and SM who were undergoing spinal correction surgery without neurosurgical intervention. During the surgery, spinal cord monitor and wake-up test were used. Preoperative, postoperative, and final follow-up major curve coronary Cobb angle, correction rate, apical vertebral rotation (AVR), apical vertebral translation (AVT), thoracic kyphosis angle (T5-T12), lumbar lordosis angle (L1-S1) were analyzed on radiographs.

RESULTS

The mean follow-up period was 82.5 months. The preoperative and postoperative mean curve coronary Cobb angle was from 55.7 ± 7.5° to 20.1 ± 5.8°, correction rate was 63.9%, AVR from 2.8 ± 0.6° to 1.3 ± 0.5°, AVT from 5.1 ± 1.4 to 1.7 ± 0.7 cm, thoracic kyphosis angle from 18.7 ± 4.0° to 32.2 ± 2.7°, lumbar lordosis angle from 36.3 ± 4.1° to 43.8 ± 3.2°. No neurological deficits occurred during the operation and follow-up.

CONCLUSIONS

Our minimum 5-year follow-up outcomes showed that in a distinct patient population of neurologically asymptomatic individuals with CM-1, SM and progressive scoliosis, posterior instrumented spinal deformity surgery can be safely done without neurosurgical interverventions with the help of preoperative flexibility evaluation and intraoperative neuromonitoring.

Functional level of lesion scale: Validating fourteen years of research with the national spina bifida patient registry

PURPOSE

Functional level of lesion (FLOL) is a grading of the level of neurological function in patients with myelomeningocele and other forms of spina bifida. It has been widely used as an independent variable in studies of spina bifida, but its inter-rater reliability has not previously been tested. The purpose of this study was to measure inter-rater reliability of FLOL testing and compare testing performed by a non-medically trained research associate to testing performed by a pediatric rehabilitation medicine specialist.

METHODS

Children in a multi-disciplinary spina bifida clinic underwent FLOL grading by a non-medically trained research associate. On the same day, these children were also graded by a pediatric rehabilitation medicine specialist. Cohen's weighted kappa statistic was used to compare grading, with the rehabilitation medicine specialist considered the gold standard.

RESULTS

A total of 71 patients participated. FLOL was graded for left and right leg for each participant, resulting in 142 measurements. Cohen's weighted kappa was κ= 0.809, with a standard error of 0.034 and 95% confidence interval 0.723-0.875, indicating substantial agreement.

CONCLUSION

FLOL as measured according to the instructions of the National Spina Bifida Patient Registry by a non-medically trained researcher is a reliable method to grade lower extremity function in spina bifida.
