ABSTRACT

INTRODUCTION: Only 20% of youth with intellectual and developmental disability (ID/DD) receive health care transition (HCT) preparation from their health care providers (HCPs). To address HCT system gaps, the first-of-its-kind HCT value-based payment (VBP) pilot was conducted for young adults (YA) with ID/DD. METHODS: This feasibility study examined the acceptability, implementation, and potential for expansion of the pilot, which was conducted within a specialty Medicaid managed care organization (HSCSN) in Washington, DC. With local pediatric and adult HCPs, the HCT intervention included a final pediatric visit, medical summary, joint HCT visit, and initial adult visit. The VBP was a mix of fee-for-service and pay-for-performance incentives. Feasibility was assessed via YA feedback surveys and interviews with HSCSN, participating HCPs, and selected state Medicaid officials. RESULTS: Regarding acceptability, HSCSN and HCPs found the HCT intervention represented a more organized approach and addressed an unmet need. YA with ID/DD and caregivers reported high satisfaction. Regarding implementation, nine YA with ID/DD participated. Benefits were reported in patient engagement, exchange of health information, and care management and financial support. Challenges included care management support needs, previous patient gaps in care, and scheduling difficulties. Regarding expansion, HSCSN and HCPs agreed that having streamlined care management support, medical summary preparation, and payment for HCT services are critical. DISCUSSION: This study examined the benefits and challenges of a HCT VBP approach and considerations for future expansion, including payer/HCP collaboration, HCT care management support, and updated system technology and interoperability.

ABSTRACT

Assisted reproductive technology (ART) includes fertility treatment in which either eggs or embryos are handled outside a female's body to promote successful pregnancies and healthy offspring. Current ART procedures encompass in vitro fertilization with or without intracytoplasmic sperm injection. The most common complication of ART is related to the consequences of multiple pregnancy, which can be prevented or minimized by reducing the number of embryos transferred to the uterus, commonly single embryo transfer. ART has been shown to be variably associated with adverse short- and long-term perinatal outcomes, including cerebral palsy, autism, neurodevelopmental imprinting disorders, and cancer. However, there is uncertainty as to whether reported problems are related to the ART procedure itself, to factors related to infertility, to other medical and environmental factors, or a combination thereof. From a pathophysiological perspective, whether ART alters epigenetic mechanisms of gene expression, leading to later developmental, medical, and behavioral disorders, is an area of active investigation. With the meticulously conducted short- and long-term outcome studies completed so far, overall, and after controlling for multiple gestations and preterm delivery, the results suggest that ART is a safe procedure, offering hope to many parent(s) wishing for a healthy child. This paper highlights ART methods and the risk factors and confounders in the interpretation of short- and long-term outcome data, providing the reader with a means to evaluate findings and conclusions of outcome studies. WHAT THIS PAPER ADDS: Assisted reproductive technology (ART) is a relatively safe procedure. Single embryo implantation optimizes outcome. Informed consent, including the risks and benefits of ART, should be required. Ongoing longitudinal studies are necessary to fully understand ART outcomes.

ABSTRACT

GM3 synthase deficiency is due to biallelic pathogenic variants in ST3GAL5, which encodes a sialyltransferase that synthesizes ganglioside GM3. Key features of this rare autosomal recessive condition include profound intellectual disability, failure to thrive and infantile onset epilepsy. We expand the phenotypic spectrum with 3 siblings who were found by whole exome sequencing to have a homozygous pathogenic variant in ST3GAL5, and we compare these cases to those previously described in the literature. The siblings had normal birth history, subsequent developmental stagnation, profound intellectual disability, choreoathetosis, failure to thrive, and visual and hearing impairment. Ichthyosis and self-injurious behavior are newly described in our patients and may influence clinical management. We conclude that GM3 synthase deficiency is a neurodevelopmental disorder with consistent features of profound intellectual disability, choreoathetosis, and deafness. Other phenotypic features have variable expressivity, including failure to thrive, epilepsy, regression, vision impairment, and skin findings. Our analysis demonstrates a broader phenotypic range of this potentially under-recognized disorder.

ABSTRACT

Holoprosencephaly (HPE) consists of a spectrum of malformations related to incomplete separation of the prosencephalon. There is a wide clinical variability depending on the HPE subtype seen on imaging. Early postnatal lethality is common, however a significant fraction of newborns diagnosed with HPE will survive into childhood and even adulthood. Here we will review the clinical management of HPE during different ages from the prenatal period to adulthood.

ABSTRACT

To increase the efficiency and effectiveness of clinical research studies, cerebral palsy (CP) specific Common Data Elements (CDEs) were developed through a partnership between the National Institute of Neurological Disorders and Stroke (NINDS) and the American Academy of Cerebral Palsy and Developmental Medicine (AACPDM). International experts reviewed existing NINDS CDEs and tools used in studies of children and young people with CP. CDEs were compiled, subjected to internal review, and posted online for external public comment in September 2016. Guided by the International Classification of Functioning, Disability and Health framework, CDEs were categorized into six domains: (1) participant characteristics; (2) health, growth, and genetics; (3) neuroimaging; (4) neuromotor skills and functional assessments; (5) neurocognitive, social, and emotional assessments; and (6) engagement and quality of life. Version 1.0 of the NINDS/AACPDM CDEs for CP is publicly available on the NINDS CDE and AACPDM websites. Global use of CDEs for CP will standardize data collection, improve data quality, and facilitate comparisons across studies. Ongoing collaboration with international colleagues, industry, and people with CP and their families will provide meaningful feedback and updates as additional evidence is obtained. These CDEs are recommended for NINDS-funded research for CP. WHAT THIS PAPER ADDS: This is the first comprehensive Common Data Elements (CDEs) for children and young people with CP for clinical research. The CDEs for children and young people with CP include common definitions, the standardization of case report forms, and measures. The CDE guides the standardization for data collection and outcome evaluation in all types of studies with children and young people with CP. The CDE ultimately improves data quality and data sharing.

ABSTRACT

PurposeWith improved medical care, some individuals with holoprosencephaly (HPE) are surviving into adulthood. We investigated the clinical manifestations of adolescents and adults with HPE and explored the underlying molecular causes.MethodsParticipants included 20 subjects 15 years of age and older. Clinical assessments included dysmorphology exams, cognitive testing, swallowing studies, ophthalmic examination, and brain magnetic resonance imaging. Genetic testing included chromosomal microarray, Sanger sequencing for SHH, ZIC2, SIX3, and TGIF, and whole-exome sequencing (WES) of 10 trios.ResultsSemilobar HPE was the most common subtype of HPE, seen in 50% of the participants. Neurodevelopmental disabilities were found to correlate with HPE subtype. Factors associated with long-term survival included HPE subtype not alobar, female gender, and nontypical facial features. Four participants had de novo pathogenic variants in ZIC2. WES analysis of 11 participants did not reveal plausible candidate genes, suggesting complex inheritance in these cases. Indeed, in two probands there was a history of uncontrolled maternal type 1 diabetes.ConclusionIndividuals with various HPE subtypes can survive into adulthood and the neurodevelopmental outcomes are variable. Based on the facial characteristics and molecular evaluations, we suggest that classic genetic causes of HPE may play a smaller role in this cohort.

ABSTRACT

An ongoing challenge in children presenting with motor delay/impairment early in life is to identify neurogenetic disorders with a clinical phenotype, which can be misdiagnosed as cerebral palsy (CP). To help distinguish patients in these two groups, conventional magnetic resonance imaging of the brain has been of great benefit in "unmasking" many of these genetic etiologies and has provided important clues to differential diagnosis in others. Recent advances in molecular genetics such as chromosomal microarray and next-generation sequencing have further revolutionized the understanding of etiology by more precisely classifying these disorders with a molecular cause. In this paper, we present a review of neurogenetic disorders masquerading as cerebral palsy evaluated at one institution. We have included representative case examples children presenting with dyskinetic, spastic, and ataxic phenotypes, with the intent to highlight the time-honored approach of using clinical tools of history and examination to focus the subsequent etiologic search with advanced neuroimaging modalities and molecular genetic tools. A precise diagnosis of these masqueraders and their differentiation from CP is important in terms of therapy, prognosis, and family counseling. In summary, this review serves as a continued call to remain vigilant for current and other to-be-discovered neurogenetic masqueraders of cerebral palsy, thereby optimizing care for patients and their families.

ABSTRACT

PURPOSE/OBJECTIVE: Successful implementation of functional self-care skills depends upon adequate executive functioning; however, many scales assessing adaptive skills do not address the inherent executive burden of these tasks. This omission is especially relevant for individuals with spina bifida, for whom medical self-care tasks impose a significant burden requiring initiation and prospective memory. The Kennedy Krieger Independence Scales-Spina Bifida Version (KKIS-SB) is a caregiver-reported measure designed to address this gap; it assesses skills for managing both typical and spina bifida-related daily self-care demands, with a focus on the timely and independent initiation of adaptive skills. RESEARCH METHOD/DESIGN: Parents of 100 youth and young adults with spina bifida completed the KKIS-SB. Exploratory factor analysis and Pearson's correlations were used to assess the factor structure, reliability, and construct validity of the KKIS-SB. RESULTS: The scale demonstrates excellent internal consistency (Cronbach's alpha = .891). Exploratory factor analysis yielded four factors, explaining 65.1% of the total variance. Two primary subscales were created, initiation of routines and prospective memory, which provide meaningful clinical information regarding management of a variety of typical (e.g., get up on time, complete daily hygiene routines on time) and spina bifida-specific self-care tasks (e.g., begin self-catheterization on time, perform self-examination for pressure sores). CONCLUSIONS/IMPLICATIONS: Based upon internal consistency estimates and correlations with measures of similar constructs, initial data suggest good preliminary reliability and validity of the KKIS-SB.

ABSTRACT

This study examined the agreement and consistency of parent- and self-report of executive functioning (EF) (Behavior Rating Inventory of Executive Functions; BRIEF) in an adolescent cohort of youth with myelomeningocele and shunted hydrocephalus (MMH). A total of 30 youth participants with MMH and their parents were recruited during adolescence (age 11-18, mean age 14), and a smaller sample (n = 13) was re-evaluated during young adulthood (age 18-26, mean age 22). Parent- and self-report T-scores were moderately correlated during adolescence (General Executive Composite, GEC, r = .504, p = .007) and adulthood (GEC, r = .571, p = .041). Compared to adolescent self-ratings, parent-ratings suggested higher levels of overall executive dysfunction and problems with metacognitive abilities during adolescence. Preliminary results from a small follow up sample, however, suggest that self- and parent-report of executive functioning may become more comparable during young adulthood. These preliminary data also suggest stability of deficit and/or possible improvement in executive presentation during the transition from adolescence to adulthood in this clinical population. Implications of these findings are discussed.

ABSTRACT

AIM: To advance understanding of the interrelationships of sex, level of lesion (LOL), self-management, community integration (employment, independent living), and quality of life (QOL) in young adults with myelomeningocele. METHOD: A multicenter convenience sample of 50 individuals with myelomeningocele, 18 to 25 years of age (mean age 21 y 5 mo, SD 2 y), participated in a structured clinical interview on self-management (Adolescent Self-Management and Independence Scale II [AMIS II]) and completed a self-report questionnaire comprising standardized measures. QOL was assessed using the World Health Organization Quality of Life (WHOQOL)-BREF instrument. A chart review yielded clinical data. RESULTS: Most participants were Caucasian (78%), female (56%: 28 females, 22 males), unemployed (58%), and in supervised living environments (74%). Eighty per cent had a history of hydrocephalus requiring shunt placement. A lumbar LOL was most frequently reported (64%), followed by a sacral LOL (22%), and thoracic LOL (7%). Males were more likely to report employment (p=0.008), but females had greater success in transitioning into independent living settings (p=0.015). LOL was a significant predictor of specific dimensions of self-management, employment, and QOL (p < 0.05). Mean scores on the AMIS II reflected deficits in condition management activities and tasks of everyday life. Limited QOL was also observed. INTERPRETATION: The overall low rates of employment and independent living suggest that individuals with myelomeningocele are experiencing great difficulty in achieving these milestones of emerging adulthood, regardless of sex. Limited success in developing self-management skills and restricted QOL also highlight vulnerability in this population.

ABSTRACT

BACKGROUND: In health care workers, the natural rubber latex (NRL) allergy phenotype has been shown to be associated with promoter polymorphisms in interleukins 13 and 18 (IL13 and IL18) when compared with nonatopic controls. However, it is not known whether high-risk patient populations, such as those born with neural tube defects or genitourinary abnormalities, demonstrate a heightened propensity toward the same genetic/immunologic risk factors that have been reported for health care workers. In this study, we tested the hypothesis that single-nucleotide polymorphisms in genes encoding IL13 and IL18 occur at an increased frequency in NRL allergic patients with spina bifida (SB) or bladder exstrophy (BE). METHODS: One hundred twenty subjects (40 SB, 40 BE, and 40 control) were screened using a clinical history questionnaire and NRL-specific immunoglobulin E (IgE) antibody measurements in the blood. Genomic DNA was extracted from peripheral blood lymphocytes and analyzed for single-nucleotide polymorphisms in candidate genes of interest. Univariate and multivariate analyses were performed to identify significant variables with significance defined as P < 0.05. RESULTS: Sensitization (IgE antibody positivity) to NRL allergens was associated with atopic history and number of prior operations and was prevented by the avoidance of NRL beginning at birth. However, unlike health care workers, the NRL allergy phenotype was not significantly associated with promoter polymorphisms in IL13 or IL18 when comparing NRL allergic SB and BE patients with nonsensitized patients and with atopic and nonatopic controls. CONCLUSIONS: In patients born with SB or BE, environmental factors seem to play a greater role in the development of NRL sensitization and overt allergic symptoms than the IL polymorphisms in IL13 and IL18 previously shown to be associated with NRL allergy in health care workers.

ABSTRACT

Holoprosencephaly (HPE) is the most common malformation of the embryonic forebrain in humans. Although HPE occurs along a continuous spectrum, it has been categorized into four types from most severe to least severe: alobar, semilobar, lobar, and middle interhemispheric (MIH) variant. Facial malformations are often associated with HPE and usually correlate with the severity of brain malformation. With the most severely affected newborns, there is a high mortality rate in the first month of life, however, with milder forms of HPE, the majority survive beyond infancy. The Carter Centers for Brain Research in Holoprosencephaly and Related Malformations have enrolled 182 living children in a prospective research study. Based on previously published reports using this database, reports from other investigators, as well as our experience and personal observations, the range of developmental, neurological, and medical problems found in children with HPE is described in this article. Virtually all children with HPE have some developmental disability and the severity correlates with the severity of the brain malformation on neuroimaging. Common medical problems include hydrocephalus, seizures, motor impairment, oromotor dysfunction with risk of poor nutrition and aspiration, chronic lung disease, gastroesophageal reflux, constipation, hypothalamic dysfunction with disturbed sleep-wake cycles and temperature dysregulation, as well as endocrine dysfunction. Diabetes insipidus in particular is found in about 70% of children with classic HPE. Recommendations for management of these problems are given based on experiences of the authors and familiarity with the literature.

ABSTRACT

BACKGROUND: Holoprosencephaly (HPE), the most common malformation of the human forebrain, may be due to mutations in genes associated with non-syndromic HPE. Mutations in ZIC2, located on chromosome 13q32, are a common cause of non-syndromic, non-chromosomal HPE. OBJECTIVE: To characterise genetic and clinical findings in patients with ZIC2 mutations. METHODS: Through the National Institutes of Health and collaborating centres, DNA from approximately 1200 individuals with HPE spectrum disorders was analysed for sequence variations in ZIC2. Clinical details were examined and all other known cases of mutations in ZIC2 were included through a literature search. RESULTS: By direct sequencing of DNA samples of an unselected group of unrelated patients with HPE in our NIH laboratory, ZIC2 mutations were found in 8.4% (49/582) of probands. A total of 157 individuals from 119 unrelated kindreds are described, including 141 patients with intragenic sequence determined mutations in ZIC2. Only 39/157 patients have previously been clinically described. Unlike HPE due to mutations in other genes, most mutations occur de novo and the distribution of HPE types differs significantly from that of non-ZIC2 related HPE. Evidence is presented for the presence of a novel facial phenotype which includes bitemporal narrowing, upslanting palpebral fissures, a short nose with anteverted nares, a broad and well demarcated philtrum, and large ears. CONCLUSIONS: HPE due to ZIC2 mutations is distinct from that due to mutations in other genes. This may shed light on the mechanisms involved in formation of the forebrain and face and will help direct genetic counselling and diagnostic strategies.

ABSTRACT

OBJECTIVE: Based on social ecological theory, this study was designed to examine the unique relationships between multi-level ecological factors and psychological symptoms in young adults with spina bifida (SB). METHOD: A sample of 61 individuals with SB, 18-25 years of age, completed standardized self-report measures of attitude toward SB, satisfaction with family functioning, Chronic Care Model (CCM) services, and depressive and anxiety symptoms. A chart review yielded SB clinical data. RESULTS: High rates of depressive and anxiety symptoms were found. Hierarchical regression analysis identified the proximal individual (attitude toward SB) and family (satisfaction with family functioning) factors as more strongly related to depressive symptoms than the distal healthcare system factor (CCM services). Self-reported pain was the only ecological factor associated with anxiety symptoms. CONCLUSIONS: Study findings provide a potential foundation for multi-factor screening of young adults with SB at risk for psychological symptoms.

ABSTRACT

AIM: Cerebral palsy (CP) is frequently linked to white matter injury in children born preterm. Diffusion tensor imaging (DTI) is a powerful technique providing precise identification of white matter microstructure. We investigated the relationship between DTI-observed thalamocortical (posterior thalamic radiation) injury, motor (corticospinal tract) injury, and sensorimotor function. METHOD: Twenty-eight children born preterm (16 males, 12 females; mean age 5y 10mo, SD 2y 6mo, range 16mo-13y; mean gestational age at birth 28wks, SD 2.7wks, range 23-34wks) were included in this case-control study. Twenty-one children had spastic diplegia, four had spastic quadriplegia, two had hemiplegia, and one had ataxic/hypotonic CP; 15 of the participants walked independently. Normative comparison data were obtained from 35 healthy age-matched children born at term (19 males, 16 females; mean age 5y 9mo, SD 4y 4mo, range 15mo-15y). Two-dimensional DTI color maps were created to evaluate 26 central white matter tracts, which were graded by a neuroradiologist masked to clinical status. Quantitative measures of touch, proprioception, strength (dynamometer), and spasticity (modified Ashworth scale) were obtained from a subset of participants. RESULTS: All 28 participants with CP had periventricular white-matter injury on magnetic resonance imaging. Using DTI color maps, there was more severe injury in the posterior thalamic radiation pathways than in the descending corticospinal tracts. Posterior thalamic radiation injury correlated with reduced contralateral touch threshold, proprioception, and motor severity, whereas corticospinal tract injury did not correlate with motor or sensory outcome measures. INTERPRETATION: These findings extend previous research demonstrating that CP in preterm children reflects disruption of thalamocortical connections as well as descending corticospinal pathways.

ABSTRACT

PURPOSE: We studied the impact of abnormal bladder function due to congenital urological disorders on health related quality of life in children. A reliable patient based method is needed to assess the impact of these conditions in children and the interventions used to treat them. MATERIALS AND METHODS: Participants 11 to 17 years old with bladder exstrophy-epispadias complex, spina bifida or other causes of abnormal bladder function self-administered the Child Health and Illness Profile-Adolescent Edition, a generic health related quality of life instrument. They also responded to questions about incontinence, catheterization status and bother level. Mean scores on the profile were compared to population based norms. RESULTS: Mean age of the 50 participants was 14.9 years, 62% were male and 82% were white. Diagnoses included bladder exstrophy-epispadias complex in 37 patients, spina bifida in 10 and other in 3. The mean +/- SD score on the disorders domain of 14.2 +/- 6.3 was significantly worse than the population norm of 20. Mean scores on the satisfaction, discomfort, resilience, risks and achievement domains were comparable to or better than the population based norm of 20. A total of 29 participants reported incontinence and 31 performed catheterization. CONCLUSIONS: In this study of adolescents with congenital causes of abnormal bladder function Child Health and Illness Profile-Adolescent Edition generic health related quality of life scores were significantly worse in the disorders domain but largely comparable to or better than those of the general population in other domains. This suggests that the profile may discern between adolescents with structural urological disease and norms but it may not be sensitive enough to fully detect the impact of the condition. Alternatively adolescents may adapt well to the challenges of urological disease.

ABSTRACT

PURPOSE: Modern principles for treatment of patients with myelomeningocele include early closure of the neural tube defect, neurosurgical treatment of hydrocephalus and treatment aimed at minimizing contractures and joint dislocations. The aim is to achieve a better survival rate and a better quality of life (QOL). Better ambulatory function is thought to improve the management of activities of daily living. This study focused on evaluating which factors might affect ambulation, function and health-related QOL in children with myelomeningocele. METHODS: Thirty-eight patients with neurological deficit from myelomeningocele were examined in an unbiased follow-up. This included a physical examination using validated methods for ambulatory function and neuromuscular status, chart reviews and evaluation of radiographs in terms of hip dislocation and spine deformity. The Pediatric Evaluation of Disability Inventory (PEDI) was used to measure mobility, self-care and social function, and the Child Health Questionnaire (CHQ-PF50) was used to measure QOL. RESULTS: Muscle function class, quadriceps strength, spasticity in hip and/or knee joint muscles and hip flexion contracture as well as the ambulatory level all affected functional mobility as well as self-care/PEDI. Patients with hip dislocation, spinal deformity or those who were mentally retarded also had significantly worse functional mobility. Besides being affected by the severity of the neurological lesion, self-care/PEDI was significantly impaired by hip flexion contracture and absence of functional ambulation. General health-related QOL was significantly lower in this patient group than for US norms. Nonambulatory and mentally retarded patients had a significantly lower physical function of their QOL (CHQ). CONCLUSIONS: The severity of the disease, i.e. reduced muscle strength and occurrence of spasticity around hip/knee, affected ambulation, functional mobility and self-care. Acquired deformities (hip dislocation and spine deformity) affected functional ambulation only. Patients with reduced functional mobility and self-care experienced lower physical QOL. Children with myelomeningocele had significantly reduced QOL compared to healthy individuals.

ABSTRACT

INTRODUCTION: We studied the fracture history in a large population of patients with cerebral palsy to determine which children were at the highest risk for fracture. METHODS: The International Classification of Diseases (Ninth Revision) coding identified 763 children with cerebral palsy. Patients and caregivers were contacted for information about fracture history and risk factors for low bone density. Of the 763 children identified, 418 children (54.8%) were available for this study; 243 (58%) had quadriplegia, 120 (29%) diplegia, and 55 (13%) hemiplegia. Three hundred sixty-six children were spastic, 23 mixed tone, 13 athetoid, and 16 classified as others. We identified 50 children (12%) who fractured; 15 of these same children had, over time, multiple fractures. RESULTS: The number of fractures showed a normal distribution by age, with a mean of 8.6 (SD, 4.0). Children with cerebral palsy with mixed tone had a higher rate of fracture (chi = 14.7, P < 0.01); chi analysis indicated that the children who fractured were, as a group, more likely to use a feeding tube, have a seizure disorder, take valproic acid (VPA), and use standing equipment in therapy. Multiple regression analysis demonstrated older age and VPA use as predictive of fracture and gave the following equation: fracture = -0.01 + (VPA x 0.17) + (age x 0.15). The subgroup that sustained multiple fractures were older at the time of first fracture than the children who had only one reported fracture (t = -2.3, P < 0.05). CONCLUSIONS: The main finding of our article is that older age at first fracture and use of VPA are predictive of fractures and define a group of children with cerebral palsy who may benefit from treatment interventions to increase bone density.

ABSTRACT

OBJECTIVE: To investigate the incidence of endocrinopathies in holoprosencephaly (HPE) and correlate the severity of the endocrinopathies with the neuroanatomic abnormalities. STUDY DESIGN: We reviewed the histories and medical records of 117 children with HPE for endocrinopathies and related treatments. Neuroimaging studies were graded for severity of HPE, hypothalamus non-separation, and pituitary abnormalities. RESULTS: Diabetes insipidus (DI) occurred in 70% of patients with classic HPE. The severity of the DI correlated with the grade of HPE and hypothalamic non-separation (p < 0.0001). Anterior pituitary dysfunctions were much less common. Hypothyroidism was identified in 11% of patients, hypocorticism in 7%, and growth hormone deficiency in 5%. Only one patient with middle interhemispheric variant of holoprosencephaly (MIH) had any of these disorders. CONCLUSIONS: Patients with HPE have a high incidence of DI that may be related to the failure of cleavage of hypothalamic nuclei. Anterior pituitary dysfunctions are much less common than DI.

ABSTRACT

Children with cerebral palsy (CP) develop difficulties with swallowing and bowel motility, although the underlying etiology of these disorders is unclear. The authors identified three children treated at their institution in the past 6 years who developed severe gastrointestinal dysfunction leading to gastric rupture after orthopaedic surgery; all three had a history that included CP (subtype spastic quadriparesis), low cognitive function, and gastrointestinal motility disorders. All three cases were fatal; in two patients the diagnosis was made at autopsy. No case of postoperative gastric rupture has been identified in children undergoing orthopaedic surgery without concomitant CP at the authors' institution. In this case series, they describe the preoperative and postoperative course of these three children. Since the only cure for gastric rupture is prompt surgical attention, orthopaedists should consider gastric rupture in the differential diagnosis of a postsurgical CP patient who becomes acutely unstable.
