Introduction

The objective of this study was to confirm previous risk factors for concussion recovery in a diverse pediatric sample and to elucidate the pathways by which individual mental health factors influence postconcussive symptom reporting and time to clearance.

Methods

Subjects between 13 and 17 years of age (N = 642; mean age = 15.40; 45% female) were analyzed from a prospectively completed database associated with a multidisciplinary TBI/concussion clinic in the southwest United States. Fifty-four percent of participants identified as Hispanic, 41% received medical coverage through Medicaid, and 54% were injured during participation in an organized sports team. Mediation analysis using a structural equational framework was employed to examine the significance of both direct and indirect effects from preinjury factors (e.g., prior concussions, female gender, history of migraines, anxiety, depression, attention-deficit/hyperactivity disorder [ADHD], and learning disorders) on postinjury symptom reporting (at baseline and visit 1) and time to clearance.

Results

Higher symptom reporting at baseline was significantly associated with history of anxiety, depression, ADHD, headaches, and female gender. Higher symptom reporting at visit 1 was significantly associated with baseline symptoms, female gender, and history of anxiety. Symptom scores at baseline fully accounted for the relation between history of depression and symptom scores at visit 1 and only partially accounted for the relation between history of anxiety and symptom scores at visit 1. Only history of anxiety indirectly contributed to greater days to clearance through higher symptom scores at visit 1.

Discussion

This study supports the concept that heterogenous experience following injury is influenced by preinjury factors and extends the generalizability of risk factors to a diverse sample of youth in terms of ethnicity, insurance status/type, and mechanism of injury. Anxiety and depression represent important noninjury factors that warrant considerable attention during concussion treatment and management.

Objective

A newborn with GRIN1-related early infantile developmental and epileptic encephalopathy (DEE) with striking pharmacoresistance is described with emphasis on potential therapy with memantine and vigabatrin.

Methods

The term neonate manifested electrographic and electroclinical seizures from the first day of life with focal tonic seizures with apnea, bradycardia, and desaturations and later developed epileptic spasms and a hyperkinetic movement disorder. Multiple antiseizure medication trials were unsuccessful. Brain magnetic resonance imaging displayed extensive malformations of cortical development.

Results

Whole-exome sequencing demonstrated a de novo novel GRIN1 variant (1916T > G,p.Phe639Cys), which can be associated with NMDA receptor dysfunction. Gain-of-function mutation was suspected based on phenotype correlation. Seizures markedly improved after initiation of memantine, an NMDA-receptor antagonist. Memantine was complemented by the concurrent use of vigabatrin, initiated 4 days earlier due to emergence of epileptic spasms. Significant reduction in seizures facilitated discharge from neonatal intensive care unit.

Interpretation

GRIN1-related disorders occur due to NMDA receptor dysfunction. Patients with gain-of-function GRIN1 mutations who present with the phenotype of DEE with extensive bilateral polymicrogyria may benefit from a trial of NMDA-receptor antagonist therapy and vigabatrin. Further research is warranted to better understand this markedly pharmacoresistant condition and to investigate targeted therapies in GRIN1 DEE.

Charcot-Marie-Tooth (CMT) disease represents a diverse group of inherited neuropathies with a broad spectrum of symptoms. It is the most prevalent inherited neuropathy, with an estimated prevalence ranging from 9.7 to 82 cases per 100,000 individuals. Despite this, CMT comprises only 118 of 853 inherited neuropathy entries in the Online Mendelian Inheritance in Man (OMIM) database. This comprehensive review offers a thorough examination of CMT's clinical features, subtypes, genetic underpinnings, and pathomechanisms in pediatric cases. CMT typically manifests as progressively worsening muscle weakness and atrophy, primarily affecting the distal extremities. Patients may also experience foot and ankle deformities, hand atrophy, and other systemic issues. To accurately diagnose CMT, a detailed family history, comprehensive clinical evaluation, nerve conduction studies, and relevant genetic testing are essential. Importantly, establishing a differential diagnosis is crucial during evaluation to rule out other conditions with similar presentations. This review aims to provide clinicians with a valuable resource for diagnosing and managing CMT, emphasizing the need for a streamlined and standardized approach considering advancements in genetic testing and the identification of various subtypes.

Objective

We aimed to test whether T-wave alternans (TWA), which is a marker of susceptibility to ventricular fibrillation, is abnormal in children with Angelman syndrome (AS) compared with typically developing children (TDC), and whether it can be used as a biomarker of AS.

Materials and Methods

Using surface electrocardiogram (ECG), we calculated TWA in AS and compared it between AS and TDC (Wilcoxon rank sum test). We then performed logistic regression to test TWA ability to distinguish AS from TDC.

Results

We observed higher TWA in AS than TDC (44 vs. 33 uV, p = 0.009), while heart rate did not differ (p = 0.26), nor its variability (p = 0.72). TWA values enabled discrimination between AS and TDC (p = 0.0008) with accuracy of 81%, positive predictive value of 72%, and negative predictive value of 100%.

Interpretation

Our findings suggest that ECG in children with AS contains evidence of acquired cardiac abnormality via pathologically increased TWA.

The use of dynamic magnetic resonance angiography in the diagnosis of rotational vertebral artery syndrome
Pub Date : 2024-11-08 DOI: 10.1002/cns3.20091
Chrisoula Cheronis, Grant L. Lin, Andrew Silverman, Alexandra Johnson, Sarah Lee

Background

Rotational vertebral artery (VA) syndrome represents a rare mechanical vasculopathy that can lead to vertebrobasilar insufficiency and ischemic stroke.

Objective

We describe a 10-year-old boy with a history of chronic morning emesis who presented with acute onset dizziness, gait instability, and vomiting and was diagnosed with acute ischemic posterior circulation stroke.

Interpretation

Contrast-enhanced magnetic resonance angiography (MRA) of the head and neck with dynamic positioning demonstrated loss of flow-related enhancement with head tilted to the left, conferring a diagnosis of rotational VA syndrome. He started aspirin monotherapy and subsequently underwent C1 laminectomy, with both radiographic and clinical improvement on follow-up.

Conclusion

Dynamic contrasted-enhanced MRA imaging can serve as a noninvasive alternative to digital subtraction angiography in the diagnosis of rotational VA syndrome and should be considered in suspected cases of pediatric rotational arteriopathy.

Isolated peripheral neuroleukemiosis mimicking Guillain-Barré syndrome in an adolescent with relapsed B-lymphoblastic leukemia
Pub Date : 2024-11-07 DOI: 10.1002/cns3.20095
Ethan Edmondson, Paisley Pauli, Jyotinder Punia, Daniel G. Calame

Background

Neuroleukemiosis, leukemic infiltration of the peripheral nervous system (PNS), is rare. Very few cases of isolated neuroleukemiosis, PNS leukemic infiltration without leukemia blasts in the blood or bone marrow, have been reported in pediatrics. Most cases have occurred in adults with acute myelogenous leukemia (AML) in remission who presented with peripheral neuropathy. We describe a pediatric patient presenting with isolated neuroleukemiosis mimicking Guillain-Barré syndrome.

Patient description

A 15-year-old boy presented 1 month after IVIG treatment for Guillain-Barre syndrome with worsening ataxia and weakness. He had a past medical history of B-cell acute lymphoblastic leukemia (B-ALL) in remission for 8 years. Examination revealed distal greater than proximal weakness of the bilateral lower extremities, areflexia at the Achilles tendon, and 1+ patellar and upper extremity reflexes. Initial magnetic resonance imaging (MRI) of the brain and spine were normal, and lumbar puncture revealed increased protein with uninterpretable white count due to excessive red blood cells. Repeat MRI brain and spinal cord showed extensive enlargement of all nerve roots and enhancement of the cauda equina and portions of cranial nerve VII bilaterally. Repeat lumbar puncture with cytology revealed leukemic blast cells. Blasts were not detected in peripheral blood smear or by flow cytometry. Bone marrow biopsy was also free of blast cells, confirming the diagnosis of relapsed B-ALL restricted to the nervous system.

Conclusions

Neuroleukemiosis is a rare entity with typical clinical features of mono- or polyneuropathy. It most often occurs in adults in remission from AML. However, neuroleukemiosis should also be on the differential for pediatric patients in remission from ALL presenting with neuropathy.

Altered cerebral oxygen extraction and metabolism in preterm neonates and the relationship to anemia: A noncontrast MRI study
Pub Date : 2024-10-28 DOI: 10.1002/cns3.20081
Zixuan Lin, Dan Wu, Dengrong Jiang, Hanzhang Lu, Ying Qi

Objective

The preterm brain is susceptible to structural injuries, which may be related to an imbalance between blood supply and oxygen metabolism. However, the effect of preterm birth on cerebral oxygen metabolism and its underlying mechanism have not been fully elucidated. The present study measured cerebral oxygen extraction and metabolism using noncontrast magnetic resonance imaging (MRI) methods in preterm neonates and examined its relationship with anemia of prematurity.

Methods

Fifty neonates with a gestational age of 28–42 weeks were enrolled. Cerebral oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO2) were measured with T2-relaxation-under-spin-tagging (TRUST) MRI, together with cerebral blood flow (CBF).

Results

We showed that CBF (p = 0.00021) and CMRO2 (p < 0.0001) increased with gestational age while OEF increased with postnatal age (p = 0.0013). Higher OEF was also associated with a higher Apgar score at birth (p = 0.039). Furthermore, hematocrit significantly mediates the increase of OEF with postnatal age (p < 0.001). Structural equation modeling analysis suggested a bidirectional relationship between CBF and CMRO2; both contributed to the changes in OEF.

Interpretation

These findings demonstrated an altered cerebral oxygen metabolism in preterm brain, suggesting a potential role of MRI–based oxygenation measurement in the assessment of transfusion and intervention for preterm neonates.

早产儿大脑容易受到结构性损伤,这可能与供血和氧代谢失衡有关。然而,早产对脑氧代谢的影响及其内在机制尚未完全阐明。本研究采用非对比磁共振成像(MRI)方法测量早产新生儿的脑氧汲取和代谢,并研究其与早产儿贫血的关系。 方法 选取了 50 名胎龄为 28-42 周的新生儿。采用 T2-松弛-下旋标记(TRUST)磁共振成像技术测量脑氧萃取率(OEF)和脑氧代谢率(CMRO2),同时测量脑血流量(CBF)。 结果 我们发现,CBF(p = 0.00021)和 CMRO2(p < 0.0001)随胎龄的增加而增加,而 OEF 则随产后年龄的增加而增加(p = 0.0013)。较高的 OEF 也与较高的出生 Apgar 评分相关(p = 0.039)。此外,血细胞比容对 OEF 随出生后年龄的增加有明显的中介作用(p < 0.001)。结构方程模型分析表明,CBF 和 CMRO2 之间存在双向关系;二者都对 OEF 的变化做出了贡献。 释义 这些研究结果表明早产儿脑氧代谢发生了改变,表明基于磁共振成像的氧合测量在早产新生儿输血和干预评估中具有潜在作用。

Acute onset of unilateral movements?
Pub Date : 2024-10-28 DOI: 10.1002/cns3.20089
Devan J. Peterson, Olivia S. Yale, Janetta L. Arellano

This previously healthy neurotypical 3-year-old boy presented for frequent stereotyped episodes of left facial and arm twitching with maintained awareness. An electroencephalogram (EEG) and brain magnetic resonance imaging were normal. However, due to a high concern for focal motor seizures, he was discharged on daily levetiracetam. Six days later, he was readmitted for increased irritability and continued left hemibody movements while awake and asleep. Continuous EEG captured the episodes of concern without an EEG correlate. The evaluation for toxic, metabolic, and infectious conditions, including cerebrospinal fluid studies, was unremarkable. His agitation was concerning for an adverse effect of levetiracetam, so he was switched to lacosamide. The evaluation was broadened to include autoimmune disorders.

His agitation did not improve, and then he developed low-grade fevers with continued irritability. His left hemibody movements evolved to orofacial dyskinesia and choreoathetoid movements (Video S1). He was started on intravenous immunoglobulins and methylprednisolone for probable autoimmune etiology. He was later found to have antibodies to the NMDA receptor in the cerebrospinal fluid (titer 1:5), confirming the diagnosis of anti-N-methyl-d-aspartate (NMDA)-receptor encephalitis, consistent with his behavioral change and movement disorder.

This boy illustrates the clinical presentation of anti-NMDA encephalitis in a child presenting with stereotypical hemibody movements unresponsive to antiseizure medication. His findings highlight the importance of a comprehensive evaluation and early treatment of potential autoimmune causes of acute behavioral and motor changes without signs of infection or previous seizures.

这名先前健康的 3 岁神经典型男孩因频繁出现左侧面部和手臂抽搐的刻板印象而就诊,但仍能保持意识清醒。脑电图(EEG)和脑磁共振成像均正常。然而,由于高度关注局灶性运动性癫痫发作,他出院时每天服用左乙拉西坦。六天后,他再次入院,原因是烦躁情绪加重,清醒和睡眠时左半身持续运动。连续脑电图捕捉到了这些令人担忧的发作,但没有脑电图相关性。对中毒、代谢和感染情况的评估,包括脑脊液检查,均无异常。考虑到他的躁动可能是左乙拉西坦的不良反应,因此改用拉科萨胺。他的躁动没有改善,随后出现低烧,并持续烦躁不安。他的左半身运动演变为口面部运动障碍和舞蹈运动(视频 S1)。由于可能的自身免疫病因,他开始静脉注射免疫球蛋白和甲基强的松龙。后来发现他的脑脊液中含有NMDA受体抗体(滴度为1:5),确诊为抗N-甲基-d-天冬氨酸(NMDA)受体脑炎,这与他的行为改变和运动障碍一致。他的研究结果突显了在没有感染或既往癫痫发作迹象的情况下,对急性行为和运动变化的潜在自身免疫原因进行全面评估和早期治疗的重要性:构思;调查;监督;可视化;写作-原稿;写作-审阅和编辑。奥利维亚-S-耶尔构思;调查;写作-原稿;写作-审阅和编辑。Janetta L.

Complex epilepsy phenotype associated with chromosome 2q24.2-q24.3 deletion involving sodium channel gene cluster
Pub Date : 2024-09-25 DOI: 10.1002/cns3.20087
Rima Madan, Fiorella S. Guido, Nicole Brescia

Objective

The 2q24.2-24.3 chromosome region encodes sodium channel genes important in severe childhood epilepsy, notably SCN1A linked to Dravet syndrome (DS). However, the roles of other genes, either within the SCN cluster or in the segments proximal to it, have not been clearly delineated. The combination of ketogenic diet and fenfluramine is known to provide substantial benefits to patients with DS, but there is a paucity of literature regarding its role in other developmental and epileptic encephalopathies (DEE). This report aims to further explore clinical findings and treatment outcomes in a patient with a complex epilepsy phenotype.

Methods

Our patient's extensive diagnostic evaluation revealed 14 deleted genes within the 2q24.2-24.3 chromosome region.

Results

The patient initially presented with clusters of focal motor seizures with apnea and cyanosis requiring intubation as well as prolonged hospitalizations for status epilepticus. He has baseline hypotonia, dysphagia, and developmental delay. He had a >50% reduction in his seizures following a combination of ketogenic diet and fenfluramine. His seizures are now responsive to rescue midazolam, and he no longer has status epilepticus.

Interpretation

Our patient's remarkable clinical improvement suggests that this dual therapy may be beneficial in patients with DEE exhibiting pathogenic variations in this region of chromosome 2, beyond just DS.

Witnessing abusive head trauma: Accidents show higher rates of intracranial pathologies than shaking 目睹虐待性头部创伤:与摇晃相比,意外事故中颅内病变的发生率更高
Pub Date : 2024-08-16 DOI: 10.1002/cns3.20084
Chris Brook

Objectives

This study aims to determine whether intracranial injuries, such as seizures, encephalopathy, bilateral subdural hematoma (SDH), and severe bilateral retinal hemorrhage (RH), are indicators of abusive head trauma (AHT), particularly in cases involving shaking.

Methods

Data comprising 54 witnessed shaking cases were drawn from two studies in the literature. Data of 100 witnessed accidents comes from the pediBIRN collaboration. Rates of intracranial injuries in cases of unconflicted witnessed accidents are compared to rates in cases of witnessed shaking and also to cases of unconflicted witnessed shaking. Unconflicted is defined as observed by an independent, unbiased witness, or by a potentially biased witness (such as partner) if reported prior to medical examinations.

Results

When all witnessed shaking cases were considered, including potentially biased witnesses, there are higher rates of findings commonly associated with AHT in witnessed accidents than in cases of witnessed shaking, although the difference is only statistically significant for seizures and encephalopathy. When restricted to cases when the witness was unconflicted, the rates of all findings are significantly more common in accidents than in shaking.

Interpretation

Accidents result in more severe intracranial pathologies than shaking, aligning with biomechanical studies that have shown that impact exerts greater force on the brain than violent shaking.

目的 本研究旨在确定颅内损伤,如癫痫发作、脑病、双侧硬膜下血肿(SDH)和严重的双侧视网膜出血(RH),是否是虐待性头部创伤(AHT)的指标,尤其是在涉及摇晃的病例中。 方法 54 例目睹摇晃病例的数据来自两项文献研究。100 例目击事故的数据来自 pediBIRN 合作项目。将非冲突目击事故中的颅内损伤率与目击摇晃事故中的颅内损伤率以及非冲突目击摇晃事故中的颅内损伤率进行比较。非冲突的定义是由独立、无偏见的目击者观察到的,或由可能有偏见的目击者(如伴侣)观察到的,如果在医学检查之前报告的话。 结果 如果考虑到所有目击摇晃的病例,包括可能有偏见的目击者,那么与目击摇晃病例相比,目击事故中常见的与急性高热惊厥相关的检查结果发生率更高,但只有癫痫发作和脑病方面的差异具有统计学意义。如果仅限于目击者未被误导的病例,则意外事故中所有检查结果的发生率均明显高于摇晃病例。 解释 意外事故比摇晃导致更严重的颅内病变,这与生物力学研究显示撞击比剧烈摇晃对大脑产生更大的力是一致的。
