RESUMEN
BACKGROUND/OBJECTIVES: Ataxia telangiectasia (A-T) is an inherited multisystem disorder with increased sensitivity to ionising radiation and elevated cancer risk. Although other cancer predisposition syndromes have established cancer screening protocols, evidence-based guidelines for cancer screening in A-T are lacking. This study sought to assess feasibility of a cancer screening protocol based on whole-body MRI (WB-MRI) in children and young people with A-T. DESIGN/METHODS: Children and young people with A-T were invited to undergo a one-off non-sedated 3-Tesla WB-MRI. Completion rate of WB-MRI was recorded and diagnostic image quality assessed by two experienced radiologists, with pre-specified success thresholds for scan completion of >50% participants and image quality between acceptable to excellent in 65% participants. Positive imaging findings were classified according to the ONCO-RADS system. Post-participation interviews were performed with recruited families to assess the experience of participating and feelings about waiting for, and communication of, the findings of the scan. RESULTS: Forty-six children and young people with A-T were identified, of which 36 were eligible to participate, 18 were recruited and 16 underwent WB-MRI. Nineteen parents participated in interviews. Fifteen participants (83%) completed the full WB-MRI scan protocol. The pre-specified image quality criterion was achieved with diagnostic images obtained in at least 93% of each MRI sequence. Non-malignant scan findings were present in 4 (25%) participants. Six themes were identified from the interviews: (1) anxiety is a familiar feeling, (2) the process of MRI scanning is challenging for some children and families, (3) preparation is essential to reduce stress, (4) WB-MRI provides the reassurance about the physical health that families need, (5) WB-MRI experience turned out to be a positive experience and (6) WB-MRI allows families to be proactive. CONCLUSION: This study shows that WB-MRI for cancer screening is feasible and well-accepted by children and young people with A-T and their families.

OBJECTIVES: We aimed to study the risks of relapse and long term disability in children with non-MS acquired demyelinating syndromes (ADS). METHODS: In this prospective, multi-centre study, from the 14 UK pediatric neurology centres, children (<16 years) experiencing a first episode of ADS were recruited from 2010 to 2014. Case report forms were collected prospectively. RESULTS: A total of 269 children were recruited and followed up for a median of 7.2 years. Median age at onset was 9y (IQR 9.5-14.5, 126 females). At last follow-up, 46 (18 %) had MS, 4 AQP4-Ab NMOSD and 206 (80 %) had other ADS, of which 27 (13 %) relapsed. Relapsing MOGAD was the diagnosis in 12/27, 6 were seronegative and 9 did not have antibodies tested. Frequency of relapse differed according to first presentation in non-MS ADS, being least likely in transverse myelitis (p = 0.025). In the non-MS group, MOG-Ab was predictive of relapse (HR = 8.42; p < 0.001) occurring 8 times as often decreasing over time. Long-term difficulties did not differ between children with monophasic vs relapsing diseases. CONCLUSION: The risk of relapse in non-MS ADS depends on initial diagnosis, and MOG-Ab positivity. Long-term difficulties are observed regardless of relapses and are determined by presenting phenotype.
RESUMEN
BACKGROUND: Idiopathic intracranial hypertension (IIH) is a potentially disabling condition. There is a lack of evidence and national guidance on how to diagnose and treat paediatric IIH, leading to variation in clinical practice. We conducted a national Delphi consensus via the Children's Headache Network to propose a best-practice diagnostic and therapeutic pathway. METHODS: The Delphi process was selected as the most appropriate methodology for examining current opinion among experts in the UK. 104 questions were considered by 66 healthcare professionals, addressing important aspects of IIH care: assessment, diagnosis, treatment, follow-up and surveillance. General paediatricians, paediatric neurologists, ophthalmologists, opticians, neuroradiologists and neurosurgeons with a clinical interest or experience in IIH, were invited to take part. RESULTS: The Delphi process consisted of three rounds comprising 104 questions (round 1, 67; round 2, 24; round 3 (ophthalmological), 13) and was completed between March 2019 and August 2021. There were 54 and 65 responders in the first and second rounds, respectively. The Delphi was endorsed by the Royal College of Ophthalmologists, which engaged 59 ophthalmologists for round 3. CONCLUSIONS: This UK-based Delphi consensus process reached agreement for the management of paediatric IIH and has been endorsed by the Children's Headache Network and more broadly, the British Paediatric Neurology Association. It provides a basis for a pragmatic clinical approach. The recommendations will help to improve clinical care while minimising under and over diagnosis.

BACKGROUND/OBJECTIVES: Ataxia telangiectasia (A-T) is a multiorgan disorder with increased vulnerability to cancer. Despite this increased cancer risk, there are no widely accepted guidelines for cancer surveillance in people affected by A-T. We aimed to understand the current international practice regarding cancer surveillance in A-T and agreed-upon approaches to develop cancer surveillance in A-T. DESIGN/METHODS: We used a consensus development method, the e-Delphi technique, comprising three rounds. Round 1 consisted of a Delphi questionnaire and a survey that collected the details of respondents' professional background, experience, and current practice of cancer surveillance in A-T. Rounds 2 and 3 were designed based on previous rounds and modified according to the comments made by the panellists. The pre-specified consensus threshold was ≥75% agreement. RESULTS: Thirty-five expert panellists from 13 countries completed the study. The survey indicated that the current practice of cancer surveillance varies widely between experts and centres'. Consensus was reached that evidence-based guidelines are needed for cancer surveillance in people with A-T, with separate recommendations for adults and children. Statements relating to the tests that should be included, the age for starting and stopping cancer surveillance and the optimal surveillance interval were also agreed upon, although in some areas, the consensus was that further research is needed. CONCLUSION: The international expert consensus statement confirms the need for evidence-based cancer surveillance guidelines in A-T, highlights key features that the guidelines should include, and identifies areas of uncertainty in the expert community. This elucidates current knowledge gaps and will inform the design of future clinical trials.

AIM: To explore neurological factors affecting quality of life (QoL) in children and young people with ataxia-telangiectasia (A-T), from both child and parent perspective. METHOD: 24 children/young people with A-T (mean age 11.2 ± 3.5 years; 13 males) and 20 parents were recruited, and 58% were reassessed after an average interval of 3.4 years. Participants completed the PedsQL QoL assessment. Participants with A-T underwent structured neurological examination. QoL data from 20 healthy controls and their parents was used for comparison. RESULTS: Children/young people with A-T rated their QoL higher than parental ratings across time points, with no longitudinal change. Higher age of the child participant correlated with lower parental (r = -0.43, p = .008) but not child ratings of QoL (r = -0.16, p = .380). Child and parent QoL ratings from the A-T group were lower than respective ratings from controls (ηp2 = 0.44 and ηp2 = 0.75 respectively, both p < .0005, controlled for socioeconomic status). Parental, but not child, ratings of QoL was predicted by a regression model based on neurological scores (R2 = 0.44, p=<.001). INTERPRETATION: Neurological disability does not determine child/young person QoL ratings in A-T. While certain aspects of neurological disability predict parent-proxy ratings, there is no decline in QoL over time. These results may reflect resilience in the face of a complex life-limiting disorder.

BACKGROUND: Ataxia-telangiectasia is an autosomal recessive, multi-system, and life-shortening disease caused by mutations in the ataxia-telangiectasia mutated gene. Although widely reported, there are no studies that give a comprehensive picture of this intriguing condition. OBJECTIVES: Understand the natural history of ataxia-telangiectasia (A-T), as reported in scientific literature. SEARCH METHODS: 107 search terms were identified and divided into 17 searches. Each search was performed in PubMed, Ovid SP (MEDLINE) 1946-present, OVID EMBASE 1980 -present, Web of Science core collection, Elsevier Scopus, and Cochrane Library. SELECTION CRITERIA: All human studies that report any aspect of A-T. DATA COLLECTION AND ANALYSIS: Search results were de-duplicated, data extracted (including author, publication year, country of origin, study design, population, participant characteristics, and clinical features). Quality of case-control and cohort studies was assessed by the Newcastle-Ottawa tool. Findings are reported descriptively and where possible data collated to report median (interquartile range, range) of outcomes of interest. MAIN RESULTS: 1314 cases reported 2134 presenting symptoms. The most common presenting symptom was abnormal gait (1160 cases; 188 studies) followed by recurrent infections in classical ataxia-telangiectasia and movement disorders in variant ataxia-telangiectasia. 687 cases reported 752 causes of death among which malignancy was the most frequently reported cause. Median (IQR, range) age of death (n = 294) was 14 years 0 months (10 years 0 months to 23 years 3 months, 1 year 3 months to 76 years 0 months). CONCLUSIONS: This review demonstrates the multi-system involvement in A-T, confirms that neurological symptoms are the most frequent presenting features in classical A-T but variants have diverse manifestations. We found that most individuals with A-T have life limited to teenage or early adulthood. Predominance of case reports, and case series demonstrate the lack of robust evidence to determine the natural history of A-T. We recommend population-based studies to fill this evidence gap.

For this narrative review, we found recent publications on the use and effectiveness of old therapies including nutraceuticals, such as riboflavin, vitamin D, magnesium, melatonin and talking therapies. Recent large trials of established conventional pharmaceuticals such as propranolol, pizotifen, topiramate and amitriptyline for childhood migraine have failed, but the use of a quasi-placebo in future trials could help. We reviewed the evidence for angiotensin antagonists including candesartan in adults, but found a lack of evidence for their use in children. There have been new developments in pharmaceuticals recently, including a more selective 5-HT1F agonist, lasmiditan, an effective acute treatment with no vasoconstrictor activity in adults, currently being tested in children. Also, a number of new calcitonin gene-related peptide (CGRP) antibodies and antagonists, with proven efficacy in acute treatment and/or prevention of migraine in adults, are undergoing trials in children. Peripheral nerve blocks and botulinum toxin are gaining popularity in adult practice, but we really need more good quality evidence for their effectiveness in children. Finally, electroceuticals, that is, therapeutic electric devices, are now marketed for acute and or preventative treatment, including an external trigeminal nerve stimulator (e-TNS), a non-invasive vagal nerve stimulator (nVNS), a single-pulse transcranial magnetic stimulator (sTMS) and a remote electrical neuromodulation device (REN). At the moment, evidence for their effectiveness in children is still lacking. So, there has been much progress, but mostly for adults. We are in urgent need of more migraine trials in children.

AIM: To evaluate an innovative paediatric neurorehabilitation model in relation to improving quality of neurorehabilitation and reducing length of stay (LOS) for children with acquired brain injury. METHOD: A process evaluation approach was conducted in line with Medical Research Council evaluation of complex interventions guidance. Analysis was conducted on routinely collected patient data from 2017 to 2018, including LOS and family feedback. Descriptive and inferential statistics were used for quantitative analysis and qualitative data was analysed thematically. RESULTS: Outcomes for 70 children (0-16y, median age 5y, IQR 1-11y, 46 males, 24 females) referred to the service indicated improved function and reduced complexity of need. The mean LOS was 10.6 days compared to baseline mean LOS of 41 days (2011-2012). High satisfaction from the families was recorded; however, ongoing needs and service gaps regarding long-term support were identified. INTERPRETATION: This service model is effective in delivering quality paediatric neurorehabilitation, demonstrating a sustained impact on LOS, and positive patient outcome data and family feedback for this group of patients. What this paper adds Investment in early intensive neurorehabilitation and supported discharge impacts length of stay (LOS) for children with acquired brain injury. Early intensive neurorehabilitation and supported discharge is effective. This is demonstrated by a sustained reduction in LOS, positive patient outcomes, and family feedback.

BACKGROUND: Ataxia Telangiectasia (A-T) is an inherited multisystem disorder with cerebellar neurodegeneration. The relationships between imaging metrics of cerebellar health and neurological function across childhood in A-T are unknown, but may be important for determining timing and impact of therapeutic interventions. PURPOSE: To test the hypothesis that abnormalities of cerebellar structure, physiology and cellular health occur in childhood A-T and correlate with neurological disability, we performed multiparametric cerebellar MRI and establish associations with disease status in childhood A-T. METHODS: Prospective cross-sectional observational study. 22 young people (9 females / 13 males, age 6.6-17.8 years) with A-T and 24 matched healthy controls underwent 3-Tesla MRI with volumetric, diffusion and proton spectroscopic acquisitions. Participants with A-T underwent structured neurological assessment, and expression / activity of ataxia-telangiectasia mutated (ATM) kinase were recorded. RESULTS: Ataxia-telangiectasia participants had cerebellar volume loss (fractional total cerebellar volume: 5.3% vs 8.7%, P < 0.0005, fractional 4th ventricular volumes: 0.19% vs 0.13%, P < 0.0005), that progressed with age (fractional cerebellar volumes, r = -0.66, P = 0.001), different from the control group (t = -4.88, P < 0.0005). The relationship between cerebellar volume and age was similar for A-T participants with absent ATM kinase production and those producing non-functioning ATM kinase. Markers of cerebellar white matter injury were elevated in ataxia-telangiectasia vs controls (apparent diffusion coefficient: 0.89 × 10-3 mm2 s-1 vs 0.69 × 10-3 mm2 s-1, p < 0.0005) and correlated (age-corrected) with neurometabolite ratios indicating impaired neuronal viability (N-acetylaspartate:creatine r = -0.70, P < 0.001); gliosis (inositol:creatine r = 0.50, P = 0.018; combined glutamine/glutamate:creatine r = -0.55, P = 0.008) and increased myelin turnover (choline:creatine r = 0.68, P < 0.001). Fractional 4th ventricular volume was the only variable retained in the regression model predicting neurological function (adjusted r2 = 0.29, P = 0.015). CONCLUSIONS: Quantitative MRI demonstrates cerebellar abnormalities in children with A-T, providing non-invasive measures of progressive cerebellar injury and markers reflecting neurological status. These MRI metrics may be of value in determining timing and impact of interventions aimed at altering the natural history of A-T.

Ataxia is a common presentation to an acute paediatric unit and it can often be difficult to determine the cause. It is important to distinguish between serious causes, for example, brain tumours and encephalitis, and more benign causes in order to guide investigations and treatment. In this review, we describe the different types of ataxia, the causes associated with them, the examination findings and what investigations to perform in order to make a diagnosis.

Whether the integrity of normal-appearing white matter (NAWM) is preserved in neuromyelitis optica spectrum disorders (NMOSD) is open to debate. To examine whether the tissue integrity of NAWM in NMOSD is compromised compared to that in healthy controls and patients with multiple sclerosis (MS), we prospectively enrolled 14 patients with NMOSD, 12 patients with MS, and 10 controls for clinical functional assessments and quantitative imaging, including T1 relaxation time (T1) and magnetization transfer ratio (MTR) at 7 Tesla. Cognitive performance on the Paced Auditory Serial Addition Test with a 3-second interstimulus interval (PASAT-3) was significantly lower in the NMOSD compared to the MS group (mean number of correct answers, 34.1 vs. 47.6; p = 0.006), but there were no differences in disease duration or disability. Histograms of T1 and MTR maps of NAWM demonstrated a decreased peak height in patients with NMOSD compared to the healthy controls, but not compared to patients with MS. Using 7T quantitative magnetic resonance imaging (MRI), this study showed that the NAWM in patients with NMOSD is abnormal, with reduced myelin signal; this was not previously observed using MRI at a lower field strength.

OBJECTIVE: Variant ataxia-telangiectasia is caused by mutations that allow some retained ataxia telangiectasia-mutated (ATM) kinase activity. Here, we describe the clinical features of the largest established cohort of individuals with variant ataxia-telangiectasia and explore genotype-phenotype correlations. METHODS: Cross-sectional data were collected retrospectively. Patients were classified as variant ataxia-telangiectasia based on retained ATM kinase activity. RESULTS: The study includes 57 individuals. Mean age at assessment was 37.5 years. Most had their first symptoms by age 10 (81%). There was a diagnostic delay of more than 10 years in 68% and more than 20 years in one third of probands. Disease severity was mild in one third of patients, and 43% were still ambulant 20 years after disease onset. Only one third had predominant ataxia, and 18% had a pure extrapyramidal presentation. Individuals with extrapyramidal presentations had milder neurological disease severity. There were no significant respiratory or immunological complications, but 25% of individuals had a history of malignancy. Missense mutations were associated with milder neurological disease severity, but with a higher risk of malignancy, compared to leaky splice site mutations. INTERPRETATION: Individuals with variant ataxia-telangiectasia require malignancy surveillance and tailored management. However, our data suggest the condition may sometimes be mis- or underdiagnosed because of atypical features, including exclusive extrapyramidal symptoms, normal eye movements, and normal alpha-fetoprotein levels in some individuals. Missense mutations are associated with milder neurological presentations, but a particularly high malignancy risk, and it is important for clinicians to be aware of these phenotypes.

Drug-resistant epilepsy (DRE) occurs in 20%-30% of children with epilepsy with significant impact on their quality of life. Management of this group of children has greatly improved in the recent years with streamlining of epilepsy surgery services and associated quaternary multimodal evaluation. This article provides a review of DRE in children and management based on recent evidence and published opinion. We have also presented an algorithmic approach to the child with possible DRE.

Children and young people who require rehabilitation following sustaining an acquired brain injury often experience long lengths of stay (LOS) and potentially poorer recovery outcomes due to limited access to therapy and little proactive discharge planning. After stakeholder enquiry we launched a new team and pathway with a primary aim to reduce LOS. The secondary aims were to pilot an outreach model, reduce cost and improve patient and family satisfaction. We achieved a significantly improved change in quality care with a financial gain and increased patient and family satisfaction.
RESUMEN
PURPOSE: Conventional teaching is that juvenile myoclonic epilepsy (JME) and juvenile absence epilepsy (JAE) require lifelong antiepileptic drug (AED) treatment. We therefore wanted to determine how many patients attending our epilepsy service with JAE or JME went into 2â¯year remission, and then relapsed, both off and on AEDs. METHOD: This was a retrospective case-notes review. Patients with JAE and JME were systematically ascertained from clinic lists and databases at one teaching hospital. Data was extracted systematically. Simple descriptive statistics were used. RESULTS: JAE: 14/36 (39%) were seizure free on AEDs for at least 2â¯years. Of the 6 (43%) attempting AED withdrawal, all (100%) relapsed, compared with only 25% of those who did not withdraw AEDs. Only 2/5 who relapsed and restarted AEDs regained remission. JME: 32/145 (22%) were seizure free on AEDs for at least 2â¯years. Of the 10 (31%) attempting AED withdrawal, 8 (80%) relapsed, compared with only 36% of those who did not withdraw AEDs. Only 2/8 who relapsed and restarted AEDs regained remission. CONCLUSION: Remission rates for JAE and JME was lower than expected. Higher proportions of seizure free patients underwent physician-supervised withdrawal than anticipated. Relapse rates off AEDs were similar for JAE and JME, and at least twice as high as for those remaining on AEDs, and a further remission was not invariable on restarting AEDs. Our experience, comparing relapse in those withdrawing to those staying on AEDs will help in discussions with patients keen to try AED withdrawal.

OBJECTIVES: We evaluate the value of an internet-based educational animated video designed to prepare children for MRI scans, and whether this video reduces scan-related anxiety in children with a neurological disorder, and healthy controls. METHODS: Participants completed a pre- and post-scan questionnaire evaluating participant online viewing behaviour, understanding of the MRI procedure, anxiety regarding the MRI, impact of animation in preparing the child and whether the child's expectation of the MRI scan matched their experience. RESULTS: 21 children were recruited (12 healthy controls) ranging in age from 6.5 to 11.5 years. The animation was successfully accessed by participants on a range of digital devices and had high levels of approval. Children who viewed the animation had a good understanding of the MRI procedure and low anxiety levels prior to the scan, and reported that their expectations broadly matched the real-life MRI experience. Children reported that the animation positively impacted on their preparation with similar ratings before and after the scan, and the impact on preparation was rated greater by younger children. There were no group differences between healthy children and those with the neurological disorder for ratings of anxiety, impact on preparation and expectation of the experience. CONCLUSION: This evaluation demonstrates accessibility, acceptability and relevance of internet-based educational animation for typically developing children, and children with a neurodisability aged 6 to 11 years, with positive impact on preparation for MRI. Advances in knowledge: The internet-based educational animation provides a widely accessible tool to support preparation of children for non-sedated MRI.

PURPOSE: Epileptic seizures complicate the management of childhood brain tumours. There are no published standards for clinical practice concerning risk factors, treatment selection or strategies to withdraw treatment with antiepileptic drugs (AED). METHOD: we undertook a case note review of 120 patients with newly diagnosed brain tumours, referred to a regional paediatric cancer service. RESULTS: data was available on 117/120 (98%) children <18â¯years: median age at tumour presentation was 8.1 years (IQR 25°-75°: 3.6-12.7), median follow up was 33 months (IQR 25°-75°: 24-56), and 35/117 (29%) experienced seizures. A cortical tumour location was associated with the highest risk of seizures (OR: 7.1; CI 95% 2.9-17.3). At a median follow up of 24 months (IQR25°-75°: 15-48), 22/35 (63%) with seizures, had a single seizure episode, 15/35 (43%) were seizure free (SF) on AEDs, 13/35 (37%) were SF off AEDs, and 7/35 (20%) experienced continuing epileptic seizures. Overall 34/35 (97%) were treated with AEDs after a seizure, of whom 12/35 (35%) withdrew from AED medication, and although 4/35 (12%) had seizure relapse, all were after further acute events. The median duration of AED before withdrawal was 11 months (IQR25°-75° 5-14 months), and the median follow up after withdrawal was 15 months (IQR25°-75° 5-34 months). CONCLUSIONS: Seizures affect about 1/3rd of children and young people presenting with and being treated for brain tumours particularly when the tumour is in the cerebral cortex. The low risk of recurrent seizures after AED treatment justifies consideration of early withdrawal of AED after seizure control.

PURPOSE: This study aims to describe the incidence of adverse drug reactions (ADRs) in children receiving antiepileptic drugs (AEDs) and compare ADRs to the individual drugs when given as monotherapy. METHOD: Paediatric patients (≤18 years old) were enrolled for this prospective observational study over a 6-month period, between September 2015 and March 2016. Adverse reactions to antiepileptic drugs (AEDs) were elicited at the time of enrolment and after 3 months using the Paediatric Epilepsy Side Effects Questionnaire. RESULTS: A total of 1139 suspected ADRs were reported in 124 participants. Eighteen different AEDs were prescribed. Sixty-six children (53%) were receiving AED monotherapy at the time of recruitment; 34/66 (52%) of whom received new generation AEDs. Levetiracetam was the most frequently prescribed AED (62/124, 50%). When only children receiving AED monotherapy were considered, fatigue, drowsiness, weight gain, dizziness were less likely with levetiracetam (pâ¯<â¯.01). Slow thinking and decreased concentration were less likely with levetiracetam or carbamazepine than valproic acid (pâ¯<â¯.05). Five patients (four on polytherapy) discontinued AED treatment due to ADRs and 2 had a dose reduction. CONCLUSIONS: Levetiracetam and carbamazepine were better tolerated than sodium valproate.
