ABSTRACT
PURPOSE: Benign Epilepsy with Centro-Temporal Spikes (BECTS) is a pediatric epilepsy with typically good seizure control. Although BECTS may increase patients' risk of developing neurological comorbidities, their clinical care and short-term outcomes are poorly quantified. METHODS: We retrospectively assessed adherence to National Institute for Health and Care Excellence (NICE) guidelines relating to specialist referral, electroencephalogram (EEG) conduct and annual review in the care of patients with BECTS, and measured their seizure, neurodevelopmental and learning outcomes at three years post-diagnosis. RESULTS: Across ten centers in England, we identified 124 patients (74 male) diagnosed with BECTS between 2015 and 2017. Patients had a mean age at diagnosis of 8.0 (95% CI = 7.6-8.4) years. 24/95 (25%) patients were seen by a specialist within two weeks of presentation; 59/100 (59%) received an EEG within two weeks of request; and 59/114 (52%) were reviewed annually. At three years post-diagnosis, 32/114 (28%) experienced ongoing seizures; 26/114 (23%) had reported poor school progress; 15/114 (13%) were diagnosed with a neurodevelopmental disorder (six autism spectrum disorder, six attention-deficit/hyperactivity disorder); and 10/114 (8.8%) were diagnosed with a learning difficulty (three processing deficit, three dyslexia). Center-level random effects models estimated neurodevelopmental diagnoses in 9% (95% CI: 2-16%) of patients and learning difficulty diagnoses in 7% (95% CI: 2-12%). CONCLUSIONS: In this multicenter work, we found variable adherence to NICE guidelines in the care of patients with BECTS and identified a notable level of neurological comorbidity. Patients with BECTS may benefit from enhanced cognitive and behavioral assessment and monitoring.

OBJECTIVE: Subcortical band heterotopia is a rare X-linked neuronal migration disorder primarily in females often associated with drug-resistant epilepsy. The aim of this study is to review the literature for non-pharmacological treatment options of drug-resistant epilepsy in subcortical band heterotopia. MATERIAL AND METHODS: In accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we performed a systematic review. Entering the keywords "double cortex," "subcortical band heterotopia," and "subcortical laminar heterotopia," we searched Scopus and PubMed databases. We paid particular attention to type of invasive and non-invasive treatment, radiological presentation, and outcome. We also describe a related case report, managed at Alder Hey Children's Hospital, Liverpool. RESULTS: The systematic literature review yielded 25 patients with subcortical band heterotopia and drug-resistant epilepsy who underwent non-pharmacological treatment. Including our patient, 26 patients were reported. The patients' mean age at seizure onset was 6.5 years (range 0.2-23) with a female sex predilection (5.25:1). The patients' mean age at invasive or non-invasive treatment was 21.5 years (range 6.5-51). The 26 patients underwent 29 non-pharmacological treatments. Ten patients underwent corpus callosotomy; 8 patients had a formal temporal lobectomy. Three patients had focal cortical resection. Two patients respectively had multiple subpial transections, insertion of a vagal nerve stimulator, or deep brain stimulation of the bilateral anterior nuclei of the thalamus. One patient underwent responsive focal neurostimulation. Another patient had transcutaneous stimulation of the vagal nerve. Sixteen patients reported a reduction or the disappearance of the seizures; 1 patient had no improvement. The outcome of 2 patients was classified class I, of 1 patient class II, of 1 patient class III, and of 5 patients class IV according to the Engel Epilepsy Surgery Outcome Scale. CONCLUSION: Mainly corpus callosotomy and formal temporal lobectomy have been performed as non-pharmacological treatment with few cases published overall. Several other invasive procedures and one non-invasive technique are based on case reports. The small number of reported cases prevents drawing a firm conclusion as to which non-pharmacological treatment is the best treatment option for refractive epilepsy in patients with subcortical band heterotopia.

PURPOSE: Despite the potentially devastating and permanently disabling effects of paediatric arteriovenous malformations (pAVMs), there is a paucity of studies reporting long-term quality-of-life (QoL) outcomes in AVM patients. We aim to evaluate the management strategies for paediatric intracranial pAVMs in the UK and long-term QoL outcomes using a validated paediatric quality-of-life outcome measure. METHODS: In this single-centre case-series, we retrospectively reviewed a prospectively maintained database of all paediatric patients (i.e. 0-18 years old) with intracranial AVMs, who were managed at Alder Hey Children's Hospital from July 2007 to December 2021. We also collected the PedsQL 4.0 score for these patients as a measure of QoL. RESULTS: Fifty-two AVMs were included in our analysis. Forty (80%) were ruptured, 8 (16%) required emergency intervention, 17 (35%) required elective surgery, 15 (30%) underwent endovascular embolisation, and 15 (30%) patients underwent stereotactic radiosurgery. There was an 88% overall obliteration rate. Two (4%) pAVMs rebled, and there were no mortalities. Overall, the mean time from diagnosis to definitive treatment was 144 days (median 119; range 0-586). QoL outcomes were collected for 26 (51%) patients. Ruptured pAVM presentation was associated with worse QoL (p = 0.0008). Location impacted psychosocial scores significantly (71.4, 56.9, and 46.6 for right supratentorial, left supratentorial, and infratentorial, respectively; p = 0.04). CONCLUSION: This study shows a staged multi-modality treatment approach to pAVMs is safe and effective, with superior obliteration rates with surgery alone. QoL scores are impacted by AVM presentation and location regardless of treatment modality.

Proteins anchored to the cell surface via glycosylphosphatidylinositol (GPI) play various key roles in the human body, particularly in development and neurogenesis. As such, many developmental disorders are caused by mutations in genes involved in the GPI biosynthesis and remodeling pathway. We describe ten unrelated families with bi-allelic mutations in PIGB, a gene that encodes phosphatidylinositol glycan class B, which transfers the third mannose to the GPI. Ten different PIGB variants were found in these individuals. Flow cytometric analysis of blood cells and fibroblasts from the affected individuals showed decreased cell surface presence of GPI-anchored proteins. Most of the affected individuals have global developmental and/or intellectual delay, all had seizures, two had polymicrogyria, and four had a peripheral neuropathy. Eight children passed away before four years old. Two of them had a clinical diagnosis of DOORS syndrome (deafness, onychodystrophy, osteodystrophy, mental retardation, and seizures), a condition that includes sensorineural deafness, shortened terminal phalanges with small finger and toenails, intellectual disability, and seizures; this condition overlaps with the severe phenotypes associated with inherited GPI deficiency. Most individuals tested showed elevated alkaline phosphatase, which is a characteristic of the inherited GPI deficiency but not DOORS syndrome. It is notable that two severely affected individuals showed 2-oxoglutaric aciduria, which can be seen in DOORS syndrome, suggesting that severe cases of inherited GPI deficiency and DOORS syndrome might share some molecular pathway disruptions.

Background: Cerebrovascular disorders represent a group of uncommon, heterogeneous, and complex conditions in children. We reviewed the screening practice for the detection of cerebrovascular disorder in asymptomatic children referred to our neurovascular service on the basis of a positive family history and parental and/or treating physician concern.Methods: Retrospective case-note review of referrals to our neurovascular service (July 2008-April 2018). Patients were included if the referral was made for screening, on the basis of a positive family history of cerebrovascular disorder. Symptomatic children, those with previous cranial imaging, or children under the care of a clinical geneticist (i.e. due to the child or their relative having HHT or mutations in KRIT1) were not eligible for inclusion.Results: Forty-one children were reviewed, 22 males (Median age 10.7 years, range 0.6-15.6 years). This represented 22% of the total number of referrals over a 10-year period. Twenty-nine children had an MRI/MRA brain. Twenty-eight children were referred due to a family history of intracranial aneurysm and/or subarachnoid haemorrhage, but only two had two first-degree relatives affected. Ten children were referred due to a family history of arteriovenous malformation. Three children were referred due to a family history of stroke. No cerebrovascular disease was detected during the study period (n = 29).Conclusions: Parental and/or physician concern generated a substantial number of referrals but no pathology was detected after screening. Whilst general screening guidance exists for the detection of intracranial aneurysms, consensus guidelines for the screening of children with a positive family history do not, but are required both to guide clinical practice and to assuage parental and/or physician concerns.

Presentation of a child in the A&E with altered behaviour including psychotic features is not unusual. New-onset psychotic symptoms in children pose a significant diagnostic challenge due to several reasons. First, primary psychotic conditions are uncommon in pre-pubertal children. Second, differentiating between delirium and psychosis can be difficult in children, more so in infants, toddlers and young children. Third, intervening and managing a secondary cause of psychosis can significantly optimise outcome. Prompt recognition of a possible underlying cause for a child's psychotic behaviour is essential, and at the same time challenging, in the emergency department. This article attempts to present a systematic approach to a child with acute onset of psychotic symptoms in an emergency setting.

OBJECTIVE: To socio-culturally adapt and validate a Hindi language version of ASQ-3 in Indian children aged 2-24 months. METHODS: This cross-sectional study was conducted at a tertiary-care center between March, 2017 and April, 2019. Children "at-risk" for developmental delay of either gender aged 2-24 months. Socio-cultural adaptation was done through interaction among 37 subject experts followed by validation. After piloting in 20 children, modified ASQ-3 was validated in 568 at-risk children (4 age-groups: 2-7, 7-13, 13-19 and 19-24 months). Validation was done against Development assessment scale for Indian infants (DASII). RESULTS: Results: After screening 654 children, 568 were enrolled. Among these, 420 had developmental delay on DASII while 18 failed to be identified on ASQ (4.3%). Overall sensitivity and specificity of Hindi language Indian-adaptation of ASQ-3 in detecting developmental delay were 95.9% (95%CI: 93.6%-97.5%) and 81.7% (95%CI: 74%-87.9%), respectively with a positive predictive value (PPV) of 94.6% (95%CI: 92%-96.5%) and negative predictive value (NPV) of 85.6% (95%CI: 78.2%-92.2%). The sensitivity and specificity for motor delay were 96.1% (93.8%-97.7%) and 92.4% (86.4%-96.3%) [PPV: 97.7% (95.8%-98.9%); NPV: 87.7% (81%-92.7%)]. Sensitivity and specificity for mental delay were 95.5% (93.1%-97.2%)and 95.3% (90.1%-98.3%) [PPV: 98.6% (97%-99.5%); NPV: 85.9% (79.1%-91.2%)]. CONCLUSION: The Hindi language Indian-adaptation of ASQ-3 had good psychometric properties with high sensitivity for developmental delay (95.9%), mental delay (95.5%), and motor delay (96.1%), suggesting it to be a good screening tool for neurodevelopmental delay.

INTRODUCTION: The top research priority for cavernoma, identified by a James Lind Alliance Priority setting partnership was 'Does treatment (with neurosurgery or stereotactic radiosurgery) or no treatment improve outcome for people diagnosed with a cavernoma?' This pilot randomised controlled trial (RCT) aims to determine the feasibility of answering this question in a main phase RCT. METHODS AND ANALYSIS: We will perform a pilot phase, parallel group, pragmatic RCT involving approximately 60 children or adults with mental capacity, resident in the UK or Ireland, with an unresected symptomatic brain cavernoma. Participants will be randomised by web-based randomisation 1:1 to treatment with medical management and with surgery (neurosurgery or stereotactic radiosurgery) versus medical management alone, stratified by prerandomisation preference for type of surgery. In addition to 13 feasibility outcomes, the primary clinical outcome is symptomatic intracranial haemorrhage or new persistent/progressive focal neurological deficit measured at 6 monthly intervals. An integrated QuinteT Recruitment Intervention (QRI) evaluates screening logs, audio recordings of recruitment discussions, and interviews with recruiters and patients/parents/carers to identify and address barriers to participation. A Patient Advisory Group has codesigned the study and will oversee its progress. ETHICS AND DISSEMINATION: This study was approved by the Yorkshire and The Humber-Leeds East Research Ethics Committee (21/YH/0046). We will submit manuscripts to peer-reviewed journals, describing the findings of the QRI and the Cavernomas: A Randomised Evaluation (CARE) pilot trial. We will present at national specialty meetings. We will disseminate a plain English summary of the findings of the CARE pilot trial to participants and public audiences with input from, and acknowledgement of, the Patient Advisory Group. TRIAL REGISTRATION NUMBER: ISRCTN41647111.

A 3-year-old boy presented with acute onset of prolonged right sided focal seizures with secondary generalisation. The investigation findings were suggestive of a neoplastic process more than an inflammatory process. Decision to perform brain biopsy from the lesion to establish the precise nature of lesion was undertaken.

Oculomotor nerve palsy can be due to varied causes that include diabetic neuropathy, myasthenia gravis, brainstem infarction, demyelinating conditions, and cerebral aneurysms. Among the aneurysmal causes of oculomotor nerve palsy, aneurysm of the posterior communicating artery has been observed to be the most common. Pupillary dysfunction is considered to be an important feature of aneurysmal oculomotor nerve paresis. A case of a 7-year-old boy with partial oculomotor nerve palsy with pupillary sparing is being reported here, the etiology of which is tortuous and ectatic distal internal carotid artery. This is a rare cause of oculomotor nerve paresis and to the best of our knowledge has not yet been reported in children. Ischemia rather than compression seems to be the most plausible cause in this case.
ABSTRACT
BACKGROUND: Guillain Barre syndrome (GBS) commonly presents with limb weakness and occasional cranial nerve, respiratory or autonomic involvement. Isolated or predominant bilateral finger drop as presenting feature has never been reported in the pediatric age group. CASE: A 9-year-old boy presented with deformity of both hands for 7 days and leg pain with difficulty in getting up from floor for 3 days. On examination he had bilateral clawing with subtle hip flexor weakness and hyporeflexia. His nerve conduction study revealed motor axonal neuropathy. His serum lead levels and autoimmune markers were within normal limits. His cerebrospinal fluid examination revealed albuminocytological dissociation. He was diagnosed as GBS and was given intravenous immunoglobulin. He improved completely over next 8 weeks. CONCLUSIONS: GBS is one of the commonest causes of acquired neuropathy in the tropics. In resource limited setting, where electrophysiological facilities may not be available, identification of finger drop sign may help in correct management.

CONTEXT: Childhood tuberculosis is a major public health problem in developing countries with tubercular meningitis being a serious complication with high mortality and morbidity. AIM: To study the clinicopathological as well as radiological profile of childhood tuberculous meningitis (TBM) cases. SETTINGS AND DESIGN: Prospective, observational study including children <14 years of age with TBM admitted in a tertiary care hospital from Western India. SUBJECTS AND METHODS: TBM was diagnosed based on predefined criteria. Glassgow coma scale (GCS) and intracranial pressure (ICP) was recorded. Staging was done as per British Medical Council Staging System. Mantoux test, chest X-ray, cerebrospinal fluid (CSF) examination, neuroimaging, and other investigations were done to confirm TB. STATISTICAL ANALYSIS USED: STATA software (version 9.0) was used for data analysis. Various risk factors were determined using Chi-square tests, and a P< 0.05 was considered significant. RESULTS: Forty-seven children were included, of which 11 (24.3%) died. Fever was the most common presenting symptom, and meningismus was the most common sign. Twenty-nine (62%) children presented with Stage III disease. Stage III disease, low GCS, and raised ICP were predictors of mortality. Findings on neuroimaging or CSF examination did not predict mortality. CONCLUSIONS: Childhood TBM presents with nonspecific clinical features. Stage III disease, low GCS, lack of Bacillus Calmette-Guérin vaccination at birth and raised ICP seem to the most important adverse prognostic factors.
