Maternal age at childbirth and the risk of attention-deficit/hyperactivity disorder and learning disability in offspring.

Background: Studies have shown that young maternal age at childbirth can increase the risk of attention-deficit/hyperactivity disorder (ADHD) in offspring, but a study of the U.S. population has not been reported. Moreover, there is no reported research on young and advanced maternal age at childbirth and whether it can contribute to the risk of learning disability (LD) in offspring. Methods: This study evaluated the association between young and advanced maternal age at childbirth and offspring risk of ADHD and LD in the U.S. population. Using data from 8,098 participants included in the National Health and Nutrition Examination Survey (NHANES) conducted in 1999-2004, we analyzed the association between maternal age at childbirth and ADHD and LD risk in offspring. Odds ratios (ORs) and 95% confidence intervals (CIs) for maternal age at childbirth in association with ADHD and LD risk in offspring were estimated using multivariate logistic regression models after adjustment for age, sex, race, body mass index (BMI), poverty income ratio, smoking status during pregnancy, and NHANES cycle. Restricted cubic spline (RCS) models were used to evaluate potential non-linear relationships. Sensitivity analyses were performed to ensure the reliability of the results. Results: Among all participants, the offspring of subjects with a maternal age at childbirth of 18-24 years had an increased risk of ADHD (OR = 1.34, 95% CI: 1.01, 1.79) and LD (OR = 1.36, 95% CI: 1.06, 1.79) or either ADHD or LD (OR = 1.48, 95% CI: 1.20, 1.81). Additionally, compared with subjects with a maternal age at childbirth of 25-29 years, subjects with a maternal age at childbirth of 35-39 years had lower odds of having offspring with ADHD (OR = 0.60, 95% CI: 0.36, 1.00) and higher odds of having offspring with LD (OR = 1.34, 95% CI: 1.01, 1.78). The relationship between maternal age at childbirth and LD risk presented a U-shaped curve. Conclusions: These results provide epidemiological evidence showing that young and advanced maternal age at childbirth are associated with ADHD and LD risk.

The NF1 microdeletion syndrome: early genetic diagnosis facilitates the management of a clinically defined disease.

Neurofibromatosis type-1 (NF1) is a genodermatosis frequently encountered in general dermatology. In many patients, the diagnosis of NF1 is made clinically based on the presence of café-au-lait macules and skinfold freckling, as well as plexiform neurofibromas detectable during early childhood. Later in life, cutaneous neurofibromas often represent important diagnostic features. NF1 is characterized by extreme clinical variability and a broad heterogeneity of NF1 gene mutations which impede genotype/phenotype correlations. Notable exceptions are NF1 microdeletions observed in 5-11 % of all NF1 patients. Patients with NF1 microdeletions frequently exhibit facial dysmorphic features and a tall stature as rather specific clinical signs. Furthermore, cutaneous and subcutaneous neurofibromas present at an early age, severe global developmental delay and cognitive disability are pathognomonic for the "NF1 microdeletion syndrome". Importantly, NF1 microdeletions are associated with an approximately twofold higher risk for malignant peripheral nerve sheath tumors than intragenic NF1 gene mutations. The severe clinical manifestations of patients with NF1 microdeletions require early multidisciplinary clinical care and frequent tumor surveillance. Therefore, when red flag features for the "NF1 microdeletion syndrome" are present in a patient, genetic testing is necessary to confirm or exclude an NF1 microdeletion.

A novel MEIS2 mutation explains the complex phenotype in a boy with a typical NF1 microdeletion syndrome.

Concurrence of distinct genetic conditions in the same patient is not rare. Several cases involving neurofibromatosis type 1 (NF1) have recently been reported, indicating the need for more extensive molecular analysis when phenotypic features cannot be explained by a single gene mutation. Here, we describe the clinical presentation of a boy with a typical NF1 microdeletion syndrome complicated by cleft palate and other dysmorphic features, hypoplasia of corpus callosum, and partial bicoronal craniosynostosis caused by a novel 2bp deletion in exon 2 of Meis homeobox 2 gene (MEIS2) inherited from the mildly affected father. This is only the second case of an inherited MEIS2 intragenic mutation reported to date. MEIS2 is known to be associated with cleft palate, intellectual disability, heart defects, and dysmorphic features. Our clinical report suggests that this gene may also have a role in cranial morphogenesis in humans, as previously observed in animal models.

Transdisciplinary Approach in Type I Neurofibromatosis - Review of Psychiatric Disorders.

BACKGROUND: Neurofibromatosis type 1 (NF1) is an autosomal dominant a multisystem genetic disorder that primarily involves the skin and the nervous system. The incidence of the disease is 1:3000-4000 live-born children, equally in both sexes. The diagnosis of NF1 is determined individually with any two of the following clinical features: café-au-lait spots, intertriginous freckling, Lisch nodules, neurofibromas, optic glioma, distinctive bone lesions and first-degree family relative with NF1. NF1 is a disease most commonly diagnosed and treated by neuropediatricians. RESULTS: Cognitive and behavioral disorders affect between 50-80% of all children with NF1. Children with NF1 show impairments in attention, visual perception, language, executive function, academic skills, and behavior. This requires a multidisciplinary approach to the treatment s as seen in the case we present. Furthermore, NF1 is often associated with psychiatric disorders, which are more frequent in this disease than in general population, according to some studies even up to 33% patients. Psychiatric disorders are more frequent in NF1 than in the general population, particularly in children. They include dysthymia, depressive mood, anxiety, and personality disorders. Bipolar mood disorders or schizophrenia are rather rare. The majority of studies have focused on physical health and neurocognitive function in NF1, whereas psychiatric disorders associated with this disease remain unclear and poorly documented. CONCLUSIONS: We present a case of an eight-year-old boy with behavioural and learning disabilities referred for psychological and psychiatric evaluation as well as an overview of NF-related psychiatric illnesses described in the literature.

Planning surgery for young people with learning disabilities.

Surgery for spinal deformity is complex and preparation involves a wide multidisciplinary team. For young people with learning disabilities, especially those who have behaviour that challenges, there are further considerations to ensure that their hospital stay is a positive experience and all their additional needs are met. Staff and carers need to be well informed and there must be effective communication. Evaluation of one patient's journey through pre-assessment, surgery and rehabilitation has identified the need for more input from learning disability liaison nurses in acute children's services.

NF1 microdeletion syndrome: a phenotypical characterization of a rare case of neurofibromatosis type 1.

Neurofibromatosis type 1 (NF1) is one of the most common neurocutaneous disorders, resulting from a wide spectrum of mutations in the NF1 gene. The NF1 microdeletion syndrome is characterized by a more severe clinical presentation than the majority of NF1 patients, with facial dysmorphic features, cognitive impairment, developmental delay, early-onset neurofibromas, and an increased risk of malignant tumors. This report provides the phenotypical characterization of a young boy diagnosed with this syndrome.

Pediatric Prevention: Academic Behavior.

Many children in the United States are performing below basic standards in reading, mathematics, and writing. Children at risk for academic problems often have comorbid classroom behavior problems and/or are diagnosed with high-incidence disabilities. Early intervention to prevent academic problems is a key goal of school-wide response-to-intervention models. The goal of school-based instructional intervention is to increase children's strength of responding so basic academic skills can be combined to solve more complex tasks. Parents and caregivers can support intervention efforts at school by engaging in frequent communication with student assistance teams and helping children with academic work completion at home.

Do Learning Disabilities Affect Testicular Cancer Survival: A National Cohort Study Between 2001 and 2015.

BACKGROUND: Some 1.5 million people in the UK have a learning disability (LD). This vulnerable group derives less benefit from population-based education programs. They are prone to underenrolment in screening programs and may lack the ability to perform self-examination. OBJECTIVE: To identify patients with LD in England and assess their testicular cancer (TC) survival in comparison to the general population. DESIGN, SETTING, AND PARTICIPANTS: Patient records were identified from the Hospital Episode Statistics database. All patients resident in England with a diagnosis of mental debility, "developmental disorder of scholastic skills", or attending under the specialty of LD between April 1, 2001 and June 30, 2015 were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We measured survival outcomes according to the Kaplan-Meier method and used log-rank tests to assess survival difference between demographic groups. RESULTS AND LIMITATIONS: Of 158138 male patients with LD, 331 had TC and 32 died of cancer. LD patients had a poorer prognosis, with 10-yr TC-specific survival of 88.4% (95% confidence interval [CI] 84.5-92.4%) in the LD group versus 96.8% (95% CI 96.6-97.1%) in the non-LD group. LD patients also had lower all-cause survival rates. The 10-yr survival rate was 77.6% (95% CI 72.2-83.3%) for LD patients versus 89.9% (95% CI 89.4-90.3%) for non-LD patients, while the corresponding 5-yr rates were 84% (95% CI 79.9-88.4%) versus 92.2% (95% CI 91.8-92.5%). CONCLUSIONS: Education regarding self-examination for TC must be provided in a format suitable for those with LD. Carers for male patients with LD should be informed about testicular examination and sinister signs. PATIENT SUMMARY: Testicular cancer patients who also have a learning disability (LD) have a one in nine chance of dying, compared to a one in 36 chance for testicular cancer patients without LD. This is because patients with LD are less likely to detect the disease at an earlier stage.

NF1 microdeletion syndrome: case report of two new patients.

BACKGROUND: 17q11.2 microdeletions, which include the neurofibromatosis type 1 (NF1) gene region, are responsible for the NF1 microdeletion syndrome, observed in 4.2% of all NF1 patients. Large deletions of the NF1 gene and its flanking regions are associated with a more severe NF1 phenotype than the NF1 general population. CASE PRESENTATION: We hereby describe the clinical and molecular features of two girls (aged 2 and 4 years, respectively), with non-mosaic atypical deletions. Patient 1 showed fifteen café-au-lait spots and axillary freckling, as well as a Lisch nodule in the left eye, strabismus, high-arched palate, malocclusion, severe kyphoscoliosis, bilateral calcaneovalgus foot, mild generalized hypotonia, hyperactivity and deficits of speech-related abilities. NF1 genomic rearrangements through multiplex ligation-dependent probe amplification (MLPA) detected an heterozygous deletion of the whole NF1 gene. Array comparative genomic hybridization (a-CGH) analysis defined a 17q11.2 deletion of about 1 Mb (breakpoints at positions 29,124,299 and 30,151,654), which involved different genes (partially CRLF3, ATAD5, TEFM, ADAP2, RNF135, OMG, EVI2B, EVI2A, RAB11FIP4), including NF1. Patient 2 showed growth and developmental delay, supravalvular pulmonary stenosis, twenty-five café-au-lait spots, axillary freckling, craniofacial dysmorphic features, short neck with pterygium, limb abnormalities and foci of neural dysplasia on brain magnetic resonance imaging (MRI). MLPA detected an heterozygous deletion of NF1, which was detailed by a-CGH indicating the positions 29,124,299 and 30,326,958 as its breakpoints, and which included aside from the genes deleted in Patient 1 also COPRS, UTP6 and partially SUZ12. Fluorescent in situ hybridization (FISH) analysis of the parents documented a de novo origin of the deletions in both cases. CONCLUSIONS: The present report will likely provide further insights and a better characterization of NF1 microdeletion syndrome.

Development of a multidisciplinary clinic of neurofibromatosis type 1 and other neurocutaneous disorders in Greece. A 3-year experience.

Given the complexity of neurocutaneous syndromes, a multidisciplinary approach has been advocated in order to provide optimum care. Subjects and Methods: Retrospective analysis of a cohort of 157 patients during a 3-year period, seen at a newly developed neurocutaneous clinic in a pediatric tertiary care hospital in Athens (Greece); and systematic chart review of the patients diagnosed with neurofibromatosis type 1 during this time period. Results: The most frequent neurocutaneous syndromes were neurofibromatosis type 1 (NF1) in 89 patients and tuberous sclerosis complex in 17. In 20.38% of patients a neurocutaneous syndrome was not confirmed. Approximately 2/3 of the NF1 patients underwent genetic analysis, and for 76.67% of them, a pathogenic mutation on the NF1 gene was revealed. Eighty-one patients manifested with generalized NF1 and eight with mosaic NF1. Dermatological manifestations included café-au-lait macules in all patients, followed by axillary and/or inguinal freckling (n = 57), external plexiform neurofibromas (n = 17), and cutaneous and subcutaneous neurofibromas (n = 11). Approximately half of patients had learning disabilities and attention deficit hyperactivity disorder, followed by mental retardation (n = 9), autistic spectrum disorders (n = 4), headaches (n = 3) and seizures (n = 2). Neuroimaging showed characteristic areas of hyperintensity on T2-weighted images in 74.07% of patients and optic pathway glioma in 19.75%. Two patients developed malignant peripheral sheath nerve tumor. Conclusions: Neurocutaneous syndromes are clinically heterogeneous and the surveillance of potential clinical complications is challenging. The availability of genetic diagnosis and novel imaging methods in this group of disorders is likely to further expand their clinical spectrum. Guidelines for assessment and management will need to be modified based on new available data.

Trastorno por déficit de atención/hiperactividad: Hábitos de estudio / Attention deficit/hyperactivity disorder. Study habits

El trastorno por déficit de atención/hiperactividad (TDAH) es uno de los trastornos más prevalentes en la población infanto-juvenil, con un impacto ya conocido sobre el aprendizaje y rendimiento escolar. La falta de atención, la disfunción ejecutiva asociada y los problemas comórbidos -particularmente los relacionados con el aprendizaje y la ansiedad-, condicionan marcadamente este dominio conceptual. Los jóvenes afectos, tienen más problemas para la toma de apuntes, finalización de trabajos, programación escolar y menor motivación al estudio. A pesar de una mayor dedicación al estudio y mayor uso de recursos de apoyo, el fracaso escolar y la no consecución de objetivos curriculares son más frecuentes en estos pacientes. El diagnóstico temprano del TDAH y sus comorbilidades, la intervención psicoeducativa y farmacológica adecuada e individualizada, han demostrado mejorar el pronóstico académico a corto y largo plazo. Para este propósito, es imprescindible la participación activa de profesionales de la salud y la educación.

Attention deficit / hyperactivity disorder (ADHD) is one of the most prevalent disorders in the child-youth population, with a known impact on learning and school performance. Lack of attention, associated executive dysfunction and comorbid problems -particularly those related to learning and anxiety-, strongly determine this conceptual domain. Affected youths have more problems for taking notes, completion of homework, school programming and less motivation to study. Despite greater dedication to homework and greater use of support resources, school failure and non-achievement of curricular objectives are more frequent in these patients. The early diagnosis of ADHD and its comorbidities, the adequate and individualized psychoeducational and pharmacological intervention, have been shown to improve academic prognosis in the short and long term. For this purpose, the active participation of health and education professionals is essential.

Mosaic Neurofibromatosis Type 1 in Children: A Single-Institution Experience.

BACKGROUND: Neurofibromatosis type 1 (NF1) is a neurocutaneous disorder caused by loss-of-function mutation in the NF1 gene. Segmental or mosaic NF1 (MNF) is an uncommon presentation of the NF1 result of postzygotic mutations that present with subtle localised clinical findings. OBJECTIVES: Our study's objectives were to describe the clinical characteristics of children with MNF. METHODS: We conducted a cross-sectional study of children diagnosed with MNF at the Hospital for Sick Children in Toronto, Canada, from January 1992 to September 2012. Data were abstracted from health records and analysed using a standardised data collection form approved by our hospital Research Ethics Board. RESULTS: We identified 60 patients with MNF; 32 of 60 (53.3%) were female. Mean ± SD age at first assessment was 10.6 ± 4.6 years. The most common initial physical manifestation in 39 of 60 (65.0%) patients was localised pigmentary changes only, followed by plexiform neurofibromas only in 10 of 60 (16.7%) and neurofibromas only in 9 of 60 (15.0%). Unilateral findings were seen in 46 of 60 (76.7%) patients. Most common associations identified included learning disabilities (7/60; 12%) and bony abnormalities (6/60; 10.0%). CONCLUSIONS: MNF is an underrecognised condition with potential implications for patients. Children mostly present with pigmentary anomalies only. Most patients do not develop associated findings or complications before adulthood, but long-term follow-up will help determine outcomes and possible associations. Recognition and confirmation of the diagnosis is important to provide follow-up and genetic counselling to patients.

Causes of mortality in individuals with tuberous sclerosis complex.

AIM: The causes of death in patients with tuberous sclerosis complex (TSC) have rarely been studied, with only one published account, which was reported from the Mayo Clinic in 1991. We aimed to investigate mortality in a large cohort of patients with TSC from one of two national referral clinics in the UK. METHOD: We identified 284 patients who attended Bath TSC clinic between 1981 and 2015, and ascertained causes of death by reviewing medical records, death certificates, and postmortem reports. RESULTS: Sixteen patients died from complications of TSC: eight from TSC kidney diseases; four from sudden unexpected death in epilepsy (SUDEP); two from lymphangioleiomyomatosis; one from a subependymal giant cell astrocytoma; and one from a pancreatic malignancy. The median age of death was 33 years (interquartile range [IQR] 26-46). Mortality was significantly more common in patients with learning disabilities than in those without (13/135 [9%] vs 3/131 [2%]; two-tailed Fisher exact test p=0.020). INTERPRETATION: Renal disease is a major cause of mortality in TSC. Lifelong surveillance and early intervention is warranted. SUDEP is also an important cause of mortality. Patients with learning disabilities are at significantly greater risk of early mortality and this implies the need for greater vigilance for TSC-related complications in this group. Female patients are vulnerable to pulmonary and renal disease. Pancreatic lesions are a rare but potentially treatable cause of mortality.

A mutation in VPS15 (PIK3R4) causes a ciliopathy and affects IFT20 release from the cis-Golgi.

Ciliopathies are a group of diseases that affect kidney and retina among other organs. Here, we identify a missense mutation in PIK3R4 (phosphoinositide 3-kinase regulatory subunit 4, named VPS15) in a family with a ciliopathy phenotype. Besides being required for trafficking and autophagy, we show that VPS15 regulates primary cilium length in human fibroblasts, as well as ciliary processes in zebrafish. Furthermore, we demonstrate its interaction with the golgin GM130 and its localization to the Golgi. The VPS15-R998Q patient mutation impairs Golgi trafficking functions in humanized yeast cells. Moreover, in VPS15-R998Q patient fibroblasts, the intraflagellar transport protein IFT20 is not localized to vesicles trafficking to the cilium but is restricted to the Golgi. Our findings suggest that at the Golgi, VPS15 and GM130 form a protein complex devoid of VPS34 to ensure the IFT20-dependent sorting and transport of membrane proteins from the cis-Golgi to the primary cilium.

Diagnóstico tardio de síndrome de DiGeorge em criança hipocalcêmica: relato de caso / Late diagnosis of DiGeorge syndrome in hypocalcemic child: case report

A Síndrome de DiGeorge (SDG) decorre de uma microdeleção 22q11.2, sendo considerada uma das microdeleções mais frequentes em humanos. Caracteriza-se por espectro fenotípico bastante amplo, incluindo dificuldade de aprendizado, fácies dismórfica, anomalias cardíacas, hipocalcemia, hipoparatireoidismo, fenda palatina, anomalias do timo, insuficiência imunológica e problemas de fala e alimentação. Contudo, nenhum achado é patognomônico ou mesmo obrigatório. Este relato de caso pretende chamar a atenção para essa síndrome como causa potencial de hipocalcemia e convulsões hipocalcêmicas mesmo após o período neonatal. Reporta-se a história clinico-laboratorial e manejo de um menino de 12 anos, diagnosticado aos sete com SDG em decorrência de facies típica e crise convulsiva hipocalcêmica. O paciente apresentava diagnóstico prévio de transtorno do déficit de atenção e hiperatividade, atraso no desenvolvimento neuropsicomotor e fácies suspeita (micrognatia, orelhas de implantação baixa, hipertelorismo, nariz angular). A hipocalcemia que deflagrou a crise convulsiva foi secundária ao hipoparatireoidismo, sendo tratado com carbonato de cálcio e calcitriol. Houve melhora clínica, porém se manteve hipocalcêmico, apesar de dose otimizada da medicação. O caso é atípico, já que o diagnóstico de SDG foi feito tardiamente, visto que a maioria dos casos é diagnosticada no período neonatal. Além disso, o quadro demonstra a variabilidade de achados clínicos que podem ser encontrados nessa síndrome e a importância de se investigar a SDG em pacientes que apresentem hipocalcemia, mesmo em idades mais avançadas. Salienta-se que o diagnostico tem relevância na implicação dos cuidados à saúde, devido aos riscos imunológicos e cardiológicos apresentados pelos pacientes portadores, devendo ser realizado o mais precocemente possível.(AU)

The DiGeorge Syndrome (DGS) stems from a 22q11.2 microdeletion and is considered one of the most frequent microdeletions in humans. It is characterized by very wide phenotypic spectrum, including learning disability, dysmorphicfacies, cardiac abnormalities, hypocalcemia, hypoparathyroidism, cleft palate, thymus abnormalities, immune impairment and speech and feeding problems. However, any finding is pathognomonic or even mandatory. This case report aims to draw attention to this syndrome as a potential cause of hypocalcemia and hypocalcemic seizures even after the neonatal period. Refers to clinical and laboratory history and management of a boy of 12, diagnosed at 07 with DGS due to typical facies and hypocalcemic seizure. The patient had a previous diagnosis of attention deficit hyperactivity disorder, developmental delay and suspected facies (micrognathia, low-set ears, hypertelorism, angular nose). Hypocalcemia that triggered the seizure was secondary to hypoparathyroidism, being treated with calcium carbon- ate and calcitriol. There was clinical improvement, but hypocalcemic remained despite optimal medication dose. The case is atypical, since the diagnosis DGS was made later, as the majority of cases are diagnosed in the neonatal period. In addition, the table shows the variability of clinical findings that can be found in this syndrome and the importance of investigating the DGS in patients who have hypocalcaemia, even at older ages. Please note that the diagnosis is relevant in the involvement of health care due to immunological and cardiac risks posed by patients and should be done as early as possible.(AU)

Academic achievement one year after resective epilepsy surgery in children.

PURPOSE: Few studies have examined the academic functioning of children following pediatric epilepsy surgery. Although intellectual functioning has been more thoroughly investigated, children with epilepsy may experience additional difficulties with academic skills. This study examined the academic outcomes of a cohort of children who underwent pediatric epilepsy surgery on an average 1.2 (standard deviation [SD]: 0.3) years prior. METHODS: Participants were 136 children (mean age: 14.3 years, [SD]: 3.7 years) who had undergone resective epilepsy surgery. Academic functioning was assessed presurgery and postsurgery using standardized tests of reading, reading comprehension, arithmetic, and spelling. RESULTS: At baseline, 65% of the children displayed low achievement (1 SD below test mean), and 28% had underachievement (1 SD below baseline IQ) in at least one academic domain. Examining change over time revealed that reading, numeral operations, and spelling significantly declined among all patients; seizure freedom at follow-up (attained in 64% of the patients) did not influence this relationship. Reading comprehension and IQ remained unchanged. Similar findings were found when examining patients with a baseline IQ of ≥ 70 and when controlling for IQ. Regression analyses revealed that after controlling for IQ, demographic and seizure-related variables were not significantly associated with academic achievement at follow-up. CONCLUSIONS: Results show baseline academic difficulties and deteriorations following surgery that go beyond IQ. Further investigations are required to determine whether the observed deteriorations result from the development of the child, the course of the disorder, or the epilepsy surgery itself. Long-term studies are warranted to identify the progression of academic achievement and whether the observed deteriorations represent a temporal disruption in function.

Unidentified undescended testes in teenage boys with severe learning disabilities.

Nine boys of secondary school age were referred with undescended testes (UDT) to paediatric surgeons over a period of 8 years. All were referred from the same community paediatric clinic for children with severe learning disabilities. UDT cause concern because of a threefold increase in the incidence of cancer. Cosmesis and reduced fertility were seen as less relevant issues for these boys. The late identification and incidence of UDT are discussed. It is suggested that awareness of this issue should be raised and screening introduced. Advice is needed on the appropriate management of UDT in this group of boys.

School Competence and Fluent Academic Performance: Informing Assessment of Educational Outcomes in Survivors of Pediatric Medulloblastoma.

Academic difficulties are widely acknowledged but not adequately studied in survivors of pediatric medulloblastoma. Although most survivors require special education services and are significantly less likely than healthy peers to finish high school, measured academic skills are typically average. This study sought to identify potential factors associated with academic difficulties in this population and focused on school competence and fluent academic performance. Thirty-six patients (ages 7-18 years old) were recruited through the Departments of Neurosurgery and Neuro-Oncology at Children's Medical Center Dallas and Cook Children's Medical Center in Fort Worth, TX. Participants completed a neuropsychological screening battery including selected Woodcock-Johnson III Tests of Achievement subtests. Parents completed the Child Behavior Checklist. School competence was significantly correlated with measured academic skills and fluency. Basic academic skill development was broadly average, in contrast to significantly worse fluent academic performance. School competence may have utility as a measure estimating levels of educational success in this population. Additionally, academic difficulties experienced by childhood medulloblastoma survivors may be better captured by measuring deficits in fluent academic performance rather than skills. Identification of these potential factors associated with educational outcomes of pediatric medulloblastoma survivors has significant implications for research, clinical assessment, and academic services/interventions.
