Objective

We present a neonate with generalized weakness due to autosomal recessive congenital myasthenic syndrome type 2C (CMS2C) resulting from a compound heterozygous mutation in the CHRNB1 gene.

Patient description

Our patient was determined by multiple methodologies to have a diagnosis of CMS2C (OMIM #616314). Whole-genome sequencing revealed two distinct variants in the CHRNB1 gene (OMIM *100710): a maternally inherited 2 kb pathogenic microdeletion on chromosome 17p13.1 and a paternally inherited intronic deletion (c.1218-9_1218-7) that was reported by the laboratory as a variant of unknown significance.

Conclusions

CMS2C is a rare autosomal recessive genetic condition associated with early-onset muscle weakness. Our patient had a paternally inherited deletion in CHRNB1 (c.1218-9_1218-7) that was initially described as a variant of unknown significance. We suggest this finding is “likely pathogenic,” as this aberration has not been commonly described. He also had a partial deletion of CHRNB1 in the maternally inherited allele, which provides further evidence that partial gene deletions may be a more common molecular mechanism than previously known for this condition. The combination of the clinical presentation and electrophysiologic data allowed us to understand the molecular findings and ultimately diagnose CMS2C in our patient.

目的 我们报告了一名因 CHRNB1 基因复合杂合突变导致常染色体隐性遗传先天性肌无力综合征 2C 型(CMS2C)而全身无力的新生儿。 患者描述 我们的患者经多种方法确诊为 CMS2C(OMIM #616314)。全基因组测序发现 CHRNB1 基因(OMIM *100710)有两个不同的变异:一个是染色体 17p13.1 上的 2 kb 母方遗传致病性微缺失,另一个是实验室报告为意义不明的父方遗传内含子缺失 (c.1218-9_1218-7)。 结论 CMS2C 是一种罕见的常染色体隐性遗传病,与早发肌无力有关。我们的患者有一个父系遗传的 CHRNB1(c.1218-9_1218-7)缺失,最初被描述为意义不明的变异。我们认为这一发现 "很可能是致病性的",因为这种畸变并不常见。他的母系遗传等位基因中还存在 CHRNB1 的部分缺失,这进一步证明部分基因缺失可能是一种比以前已知的更常见的分子机制。结合临床表现和电生理数据,我们了解了分子研究结果,并最终诊断出患者患有 CMS2C。

Background

Muscle channelopathies are a rare and heterogeneous group of disorders that can be clinically challenging and functionally disabling. These disorders can present in both adult and pediatric age groups. These disorders have been known since the turn of the 20th century, with a steady evolution in terms of understanding the pathophysiology, phenotype, diagnostic, and treatment modalities over the last three decades.

Methods

We present a comprehensive review of muscle channelopathies that includes nondystrophic myotonias and periodic paralyses. The disorders in this review have been classified based on the presence or absence of myotonia on either the clinical exam or on electrophysiological testing. The historical background, genetics, pathophysiology, phenotypic presentations, and treatment modalities of each disorder reveal similarities as well as specific nuances in the disease phenotypes. Neurophysiologic testing shows differences in responses on routine and exercise testing and can narrow the differential within subsets of nondystrophic myotonias and periodic paralyses. The advances in genetics further aid in specifying which of the putative channels are at fault. Management can then be guided by knowledge of the causative gene and involves either avoidance of triggers or channel-based therapeutics.

Conclusion

Muscle channelopathies are rare, but a high index of suspicion along with a knowledge of the phenotype will help guide neurophysiological and genetic testing. A muscle channelopathy diagnosis, subsequently, can assist in avoiding triggers and directing treatments.

背景 肌肉通道病是一类罕见的异质性疾病,在临床上具有挑战性并可导致功能障碍。这些疾病既可发生于成人,也可发生于儿童。这些疾病早在 20 世纪初就已为人所知,而在过去的 30 年中,人们对其病理生理学、表型、诊断和治疗方法的认识也在稳步发展。 方法 我们对包括非营养性肌病和周期性瘫痪在内的肌通道病进行了全面综述。本综述中的疾病根据临床检查或电生理测试中是否存在肌张力障碍进行分类。每种疾病的历史背景、遗传学、病理生理学、表型表现和治疗方法都揭示了疾病表型的相似性和细微差别。神经生理学测试显示了常规测试和运动测试反应的差异,可以缩小非肌营养不良性肌营养不良和周期性瘫痪亚群的鉴别范围。遗传学的进步进一步帮助确定哪些假定通道出现了问题。然后就可以根据致病基因的知识进行治疗,包括避免诱发因素或采用基于通道的治疗方法。 结论 肌肉通道病很少见,但高度的怀疑指数和对表型的了解有助于指导神经电生理和基因检测。肌肉通道病的诊断有助于避免诱发因素和指导治疗。

“Fifth-day fits” revisited: A literature review of benign idiopathic neonatal seizures and comparison with KCNQ2- and KCNQ3-associated benign familial epilepsy syndromes 重新审视“第五天发作”:良性特发性新生儿癫痫的文献综述及其与KCNQ2和KCNQ3相关的良性家族性癫痫综合征的比较

Benign idiopathic neonatal seizures (BINS), colloquially referred to as the “fifth-day fits,” is a clinical neonatal epilepsy syndrome associated with early, spontaneous resolution of seizures and favorable developmental outcome. Although this disease entity was first described over four decades ago, the etiopathogenesis remains unknown, and it is unclear if the syndrome represents a single, cohesive disorder or a common manifestation of various unrelated neonatal neurological disturbances. As such, there are no standardized approaches to diagnostic workup and management. Benign familial neonatal seizures (BFNS) is a well-characterized genetic syndrome associated with KCNQ2 and KCNQ3 pathogenic variants, which also manifests clinically with self-resolving seizures in the neonatal period. While it remains unclear if there is any shared pathogenesis between these two disorders, the exceedingly similar phenotypic presentations and natural history raise the question of whether consensus management approaches used in genetic BFNS can also be applied to BINS. Here, we present a topical and historical review of BINS and BFNS literature and propose specific treatment recommendations based on extrapolation of limited existing clinical data.

良性特发性新生儿癫痫发作(BINS),俗称“第五天发作”,是一种临床新生儿癫痫综合征,与癫痫发作的早期自发消退和良好的发育结果有关。尽管这种疾病在40多年前首次被描述,但其发病机制尚不清楚,目前尚不清楚该综合征是一种单一的内聚性疾病,还是各种不相关的新生儿神经系统紊乱的常见表现。因此,诊断检查和管理没有标准化的方法。良性家族性新生儿癫痫发作(BFNS)是一种与KCNQ2和KCNQ3致病性变异相关的具有良好特征的遗传综合征,在新生儿期也表现为自消退性癫痫。虽然目前尚不清楚这两种疾病之间是否有任何共同的发病机制,但极其相似的表型表现和自然史提出了一个问题,即遗传性BFNS中使用的共识管理方法是否也可以应用于BINS。在此,我们对BINS和BFNS文献进行了专题和历史回顾,并根据有限的现有临床数据提出了具体的治疗建议。

Objective

We aimed to determine the longitudinal distribution of hand function skills in individuals with classic Rett syndrome (RTT), an X-linked dominant neurodevelopmental disorder, and correlate with MECP2 variants.

Method

We conducted a longitudinal study of 946 girls and young women with typical RTT seen between 2006 and 2021 in the US Natural History Study (NHS) featuring a structured clinical evaluation to assess the level of hand function skills. The specific focus of this study was to assess longitudinal variation of hand skills from age 2 through age 18 years in relation to specific MECP2 variant groups.

Results

Following the initial regression period, hand function continues to decline across the age spectrum in individuals with RTT. Specific differences are noted with steeper declines in hand function among those with milder variants (Group A: R133C, R294X, R306C, and C-terminal truncations) compared with groups composed of individuals with more severe variants.

Conclusions

These temporal variations in hand use represent specific considerations that could influence the design of clinical trials that test therapies aiming to ameliorate specific functional limitations in individuals with RTT. Furthermore, the distinct impact of specific MECP2 variants on clinical severity, especially related to hand use, should be considered in such interventional trials.

目的我们旨在确定经典雷特综合征(RTT)患者手功能技能的纵向分布,RTT是一种X连锁显性神经发育障碍,并与MECP2变异相关。方法我们在美国自然史研究(NHS)中对2006年至2021年间946名患有典型RTT的女孩和年轻女性进行了一项纵向研究,该研究采用结构化临床评估来评估手功能技能水平。本研究的具体重点是评估从2岁到18岁与特定MECP2变体组相关的手技能的纵向变化。结果在最初的回归期之后,RTT患者的手功能在整个年龄段内持续下降。与具有更严重变异的个体组成的组相比,具有较轻变异的个体(A组:R133C、R294X、R306C和C末端截短)的手功能下降幅度更大,这是一个特殊的差异。结论这些手部使用的时间变化代表了可能影响临床试验设计的特定考虑因素,这些临床试验旨在改善RTT患者的特定功能限制。此外,在此类介入试验中,应考虑特定MECP2变体对临床严重程度的明显影响,尤其是与手部使用有关的影响。

A three-year-old girl with subacute encephalopathy, myoclonus, and regression 一名患有亚急性脑病、肌阵挛和退行性变的三岁女孩
Pub Date : 2023-08-26 DOI: 10.1002/cns3.20037

This previously healthy three-year-old girl presented with two months of developmental regression, progressive fatigue, and jerking movements in the setting of failure to thrive and macrocytic anemia. She previously spoke in full sentences but began using only one-to-two-word phrases. She would collapse after walking short distances or going up stairs. Examination revealed lethargy, irritability, myoclonic jerks of trunk and limbs, diffuse hyperreflexia with clonus, and wide-based unsteady gait. Labs showed vitamin B12 < 200 pg/mL (lowest reportable), methylmalonic acid 14 μmol/L (ref. 0.0–0.4 μmol/L), homocysteine 224 μmol/L (ref. 0–15 μmol/L), and mean corpuscular volume 110 (ref. 76–87 fL). Magnetic resonance imaging revealed no brain abnormalities, but spinal imaging showed extensive T2 hyperintensity of the dorsal columns (Figure 1). She was diagnosed with spinal cord degeneration secondary to vitamin B12 deficiency. Parenteral B12 supplementation led to rapid clinical improvement. However, without continued parenteral supplementation, she had declining B12 levels and is undergoing further investigation for a malabsorptive or genetic-metabolic etiology.

Cobalamin, or vitamin B12, is important in myelin metabolism and brain development. Pediatric B12 deficiency is most commonly due to nutritional insufficiency, malabsorption, or more rarely, genetic-metabolic syndromes.1-3 Infants and toddlers often present with developmental regression, lethargy, hypotonia, and abnormal movements such as myoclonus or chorea.1, 4 Spinal cord degeneration secondary to B12 deficiency is exceedingly rare in children in developed countries.1, 2 In terms of treatment, oral B12 replacement is sufficient in cases of nutritional deficiency. Malabsorptive or genetic-metabolic etiologies, on the other hand, are likely to require ongoing parenteral supplementation.3 Prognosis is dependent on age of onset and duration of uncorrected B12 deficiency.1

Empowering differences: Disability in child neurology training 授权差异:儿童神经学培训中的残疾
Pub Date : 2023-08-16 DOI: 10.1002/cns3.20036
Young-Min Kim, Diana M. Cejas

The article by Roach1 describes diversity implications in child neurology training, calling for initiatives toward consensus-building and change. In this letter, we call for an initiative to empower disabled physicians and to pursue a workforce that is neurodiverse.

Schor has underscored the value of developing a workforce that reflects those we serve.2 A child neurology workforce, then, should include disabled physicians, including those who identify as neurodivergent with insight regarding neurological differences that compose the human spectrum.

In the United States, disabled persons comprise nearly a quarter of adults, but only 3.1% of practicing physicians report having a disability.3 This may be an underestimate because disclosure comes with risk. Myriad obstacles prevent disabled physicians from disclosing their disability, including cultural expectations, disability stigma, and penalties that come with disclosure. This leads many to hide their disability and discourages disabled students from pursuing medical careers altogether. Likewise, neurodivergent traits are seen generally as problems in medical training despite increasing literature regarding disabled medical trainees and autistic students in higher education.4, 5 While affirmative practices may accommodate marginalized racial, gender, ethnic, and socioeconomic identities, neurodivergent traits may be seen as simply disqualifying.

Roach1的文章描述了儿童神经学培训的多样性含义,呼吁建立共识和改变的主动性。在这封信中,我们呼吁发起一项倡议,赋予残疾医生权力,并追求神经多样性的劳动力。肖尔强调了培养能反映我们所服务对象的员工队伍的价值因此,儿童神经病学工作人员应该包括残疾医生,包括那些认为神经分化的人,他们对构成人类谱系的神经差异有深刻的认识。在美国,残疾人占成年人的近四分之一,但只有3.1%的执业医生报告自己有残疾这可能被低估了,因为信息披露伴随着风险。无数的障碍阻止残疾医生透露他们的残疾,包括文化期望,残疾的耻辱,以及随之而来的惩罚。这导致许多人隐瞒自己的残疾,并使残疾学生完全不愿从事医疗事业。同样,尽管越来越多的文献关于残疾医学学员和高等教育中的自闭症学生,但神经分化特征通常被视为医学培训中的问题。虽然平权做法可以适应被边缘化的种族、性别、民族和社会经济身份,但神经分化特征可能被视为不符合资格。神经分化的个体可能不会在训练中透露他们的诊断,他们可能认为顺从——伪装或“掩盖”他们的特征,忽视他们的需求——是唯一的前进道路。当我们的文化、医疗保健和经济系统以一种不同的视角来看待残疾人和神经分化者时——我们将其视为精神障碍、行为特征的医学化、经验还原论,以及通过经济生产力对人的评估——残疾人医生满足了一种未被满足的需求。残疾医生不是象征性的个人,而是在公平社会中体现归属感的赋权个人。它们教会我们去适应,去考虑生活经验、交叉性和身份,这些对于建立共识、共同决策和目标导向的护理是不可或缺的。当医生和患者拥有共同的身份时,我们的伙伴关系就会得到加强,信任就会产生,结果就会得到改善。事实可能是,我们中间一直有残疾和神经分化的医生。我们最需要的是有勇气问自己,认识到我们之间的差异并赋予它们力量,是否能更好地反映病人的需求,使医学成为我们共同人性的一部分。如果我们作为一个专业团体追求公平和正义,而不是象征性的多样性和包容性,我们就需要提高残疾医生的地位。我们的培训体系和文化必须做出哪些改变,才能使我们的差异得到加强?金英敏:概念化;原创作品草案;写作-审查和编辑。Diana M.

Asking impertinent questions: The art of manuscript peer review 提出无礼的问题:手稿同行评审的艺术
Pub Date : 2023-07-25 DOI: 10.1002/cns3.20034
E. Steve Roach

Prepublication peer review of scientific manuscripts is used by most legitimate scientific publications. Skillful peer reviews represent a valuable contribution to the field by improving the quality of scientific research communication and promoting scientific integrity.

Peer review of scientific manuscripts was introduced in 1733 by the Royal Society of Edinburgh. In 1752, a committee of the Royal Society of London began prepublication reviews for the society's Philosophical Transactions.1 In 1893, the British Medical Journal began using outside referees for noneditorial articles.2 However, prepublication peer review of medical and scientific manuscripts did not become standard until the mid-1900s, led by the introduction of manuscript review by JAMA and Science in the 1940s and Lancet in 1976.2 The peer review process was likely facilitated by the advent of photocopy technology.3

The overlapping goals of peer review are to provide editors with an assessment of the veracity and potential significance of the submission and to help the author improve the quality of the manuscript. However, there are sometimes benefits to a reviewer as well, such as improved manuscript preparation skills, exposure to new concepts and ideas, and opportunities for improved professional standing.

A number of studies have analyzed the effectiveness of manuscript peer review, the potential effects of reviewer bias, and the authors' satisfaction with the review process.4-7 Despite the acknowledged importance of manuscript peer review, information about how to do it effectively is scant, and formal training in manuscript reviewing is usually limited. There are many different ways to complete a manuscript review, but what follows is a primer on effective manuscript peer review by an editor with years of reviewing and editing experience.

Does the manuscript pass the “smell test”? As a reviewer, you are the content expert, and editors will appreciate your placing a study into context. Are earlier publications being ignored or trivialized? Well-crafted manuscripts offer a clear explanation of their purpose, ideally in the introduction. If the reviewer struggles to grasp the manuscript's importance, so will the readers.

Rare is not the same thing as novel. Manuscripts occasionally have important implications that are not recognized by the authors. More often, the authors suggest novelty when little exists. Not all novelty is equally meaningful. I am usually unimpressed with “geographic” manuscripts (“we describe the first patient with West Nile encephalitis in all of Wyoming”), “making people aware” manuscripts (describing something that is uncommon but already well-known), “masquerading as” manuscripts, incremental data reports (adding a few more patients to last year's published summary), a

大多数合法的科学出版物都使用出版前对科学手稿的同行评审。熟练的同行评审通过提高科研交流质量和促进科学诚信,对该领域做出了宝贵贡献。1733年,爱丁堡皇家学会开始对科学手稿进行同行评审。1752年,伦敦皇家学会的一个委员会开始对该学会的《哲学汇刊》进行出版前审查。1893年,《英国医学杂志》开始在非编辑文章中使用外部推荐人。然而,直到20世纪中期,医学和科学手稿的出版前同行评审才成为标准,20世纪40年代《美国医学会杂志》和《科学》以及1976年《柳叶刀》引入了手稿评审。复印技术的出现可能促进了同行评审过程。同行评审的重叠目标是为编辑提供对稿件真实性和潜在意义的评估,并帮助作者提高稿件质量。然而,有时也会给审稿人带来好处,比如提高手稿准备技能,接触新的概念和想法,以及提高专业地位的机会。许多研究分析了手稿同行评审的有效性、评审员偏见的潜在影响以及作者对评审过程的满意度。尽管公认的手稿同行评审的重要性,但关于如何有效地进行同行评审的信息很少,手稿评审的正式培训通常也很有限。有很多不同的方法来完成稿件评审,但下面是一位具有多年评审和编辑经验的编辑对有效的稿件同行评审的入门知识。

Longitudinal imaging in Kleefstra syndrome—Brief report and literature review 克莱夫斯特拉综合征的纵向成像-简要报告和文献复习
Pub Date : 2023-07-05 DOI: 10.1002/cns3.20032

Background

Kleefstra syndrome (KS) is a rare genetic condition affecting the euchromatic histone methyltransferase 1 (EHMT1) gene, typically presenting with developmental delay, generalized hypotonia, distinctive facial dysmorphisms, and neuropsychiatric anomalies.

Methods

We collected longitudinal magnetic resonance imaging (MRI) data of a child with KS and cerebrospinal fluid (CSF) dissection over 16 years and reviewed the literature focusing on articles reporting MRI findings in KS based on a PubMed search.

Results

An 18-year-old female with KS presented with developmental delay at age 18 months and seizures at age 10 years. At age 23 months, MRI showed ventriculomegaly. Follow-up MRI nine years later showed CSF dissection from the right lateral ventricle, which progressed similarly in the contralateral side 3 years later and stabilized over time. To date, only 20 articles report MRI findings from 49 patients with KS. The brain imaging findings range from normal (about 25%) to various abnormalities, including ventriculomegaly, white matter signal abnormalities, and dysmorphic corpus callosum and brainstem structures. CSF dissection was not found in any cases with white matter or other abnormalities.

Conclusions

CSF dissection may be a rare neuroimaging finding of KS. Its etiology is unclear, but we speculate that epigenetic mutations could indirectly affect the development and integrity of ependymal cell lining along the ventricles. Alternatively, the long-standing hydrocephalus may have caused the development of pseudodiverticula and subsequent CSF dissection.

Sturge–Weber syndrome: Updates in pathogenesis, diagnosis, and treatment Sturge-Weber综合征:发病机制、诊断和治疗的最新进展
Pub Date : 2023-06-30 DOI: 10.1002/cns3.20031
Chelsea B. Valery, Anne M. Comi

Objectives

We summarize the current knowledge of Sturge–Weber syndrome (SWS) including genetic involvement, difficulties in diagnosis, symptoms caused by the vascular malformations, treatments, and future areas of research.

Methods

PubMed searches were completed between October and December of 2022 including the following search terms: Sturge–Weber neuroimaging, Sturge–Weber ocular involvement, Sturge–Weber G-protein alpha q subunit (GNAQ), Sturge–Weber presymptomatic treatment, and Sturge–Weber quantitative EEG. Clinically relevant articles and case reports were reviewed and summarized, with emphasis placed on reports from the last 20 years.

Results

Literature suggests that early identification of brain involvement is essential for optimal medical care. Infants with a port-wine birthmark on the forehead, temple, or eyelids are at risk for SWS brain and eye involvement. Neuroimaging findings include leptomeningeal enhancements, cortical calcifications, and brain atrophy, and diagnosis requires magnetic resonance imaging with and without contrast. Before 1 year of age, neuroimaging has low sensitivity and may underestimate the extent of involvement; imaging after 1 year of age is needed to exclude brain involvement. The most common underlying cause for SWS is a somatic mosaic mutation in GNAQ. Neurological symptoms include seizures, stroke or stroke-like episodes, headaches, and cognitive deficits. Recommended treatment for SWS brain involvement includes aggressive seizure control with antiepileptic medications; low-dose aspirin is also frequently but not universally utilized. Current literature suggests that children with SWS may benefit from presymptomatic treatment; further study of this approach is ongoing.

Conclusions

SWS is a rare neurovascular disorder usually signaled by a facial port-wine birthmark. Early diagnosis and appropriate treatment may improve outcomes.

我们总结了目前对斯特奇-韦伯综合征(SWS)的认识,包括遗传关系、诊断困难、血管畸形引起的症状、治疗方法和未来的研究领域。方法于2022年10月至12月完成PubMed检索,包括以下检索词:Sturge-Weber神经影像学、Sturge-Weber眼部受累、Sturge-Weber g蛋白α q亚基(GNAQ)、Sturge-Weber症状前治疗和Sturge-Weber定量脑电图。回顾和总结了临床相关的文章和病例报告,重点是近20年的报告。结果文献提示,早期识别脑受累对最佳医疗护理至关重要。前额、太阳穴或眼睑上有葡萄酒胎记的婴儿有SWS大脑和眼睛受累的风险。神经影像学表现包括脑轻脑膜增强、皮质钙化和脑萎缩,诊断需要有或没有对比的磁共振成像。1岁前,神经影像学敏感性低,可能低估受累程度;1岁后需要影像学检查以排除脑部受累。SWS最常见的潜在原因是GNAQ的体细胞镶嵌突变。神经系统症状包括癫痫发作、中风或中风样发作、头痛和认知缺陷。SWS脑受损伤的推荐治疗包括抗癫痫药物积极控制癫痫发作;低剂量阿司匹林也经常使用,但不是普遍使用。目前的文献表明,SWS儿童可能受益于症状前治疗;对这种方法的进一步研究正在进行中。结论SWS是一种罕见的神经血管疾病,通常以面部葡萄酒胎记为特征。早期诊断和适当治疗可改善预后。

A 14-month-old girl presented to the emergency department (ED) with two weeks of fever, vomiting, and new onset focal and generalized seizures and was diagnosed with tuberculosis (TB) meningitis based on imaging and serum studies, later confirmed by a TB-specific culture of the cerebral spinal fluid (CSF, acid-fast bacilli culture). She was started on anti-TB combination therapy (rifampin, isoniazid, pyrazinamide, and levofloxacin). One month later she returned to the ED with 10 days of fussiness, beginning after receiving scheduled vaccinations. Neuroimaging revealed intraparenchymal and leptomeningeal tuberculomas surrounding the anterior and posterior circulation (middle panel), which were absent from prior imaging (left panel). Repeat CSF cultures were negative for TB or other infections, leading to a diagnosis of paradoxical TB immune reconstitution inflammatory syndrome (TB-IRIS). She was started on steroids, and tuberculomas resolved within six months (right panel). She has remained seizure-free but has persistent delays in communication.

Paradoxical TB-IRIS is a severe immune response that causes clinical worsening of TB lesions following initiation of appropriate treatment.1 Though rare, neurological symptoms from TB-IRIS develop at a median of 60 days after treatment.1, 2 Imaging classically demonstrates tuberculomas and/or meningitis. Patients are at a high risk of stroke given the tendency to develop lesions within the basal cisterns. Young children may be at higher risk of complications because their symptoms are often nonspecific (e.g., fussiness), leading to a delay in diagnosis (Figure 1).

一名14个月大的女婴以两周的发热、呕吐和新发局灶性和全局性癫痫就诊于急诊科(ED),根据影像学和血清检查诊断为结核性脑膜炎(TB),后来通过脑脊液结核特异性培养(CSF,抗酸杆菌培养)确诊。她开始接受抗结核联合治疗(利福平、异烟肼、吡嗪酰胺和左氧氟沙星)。一个月后,她回到急诊科,在接受了预定的疫苗接种后,她开始了10天的焦虑。神经影像学显示肺实质内和轻脑膜结核瘤环绕前后循环(中图),先前影像学未见(左图)。重复脑脊液培养结核或其他感染呈阴性,导致诊断为矛盾结核免疫重建炎症综合征(TB- iris)。她开始使用类固醇,结核瘤在6个月内消退(右图)。她一直没有癫痫发作,但在沟通方面一直存在延迟。矛盾的结核病- iris是一种严重的免疫反应,在开始适当治疗后会导致结核病病变的临床恶化虽然罕见,但结核- iris的神经系统症状在治疗后中位数为60天出现。影像学典型表现为结核瘤和/或脑膜炎。患者中风的风险很高,因为有在基底池内发展病变的倾向。幼儿可能有更高的并发症风险,因为他们的症状通常是非特异性的(例如,大惊小怪),导致诊断延误(图1)。原创作品草案;写作-审查和编辑。Fábio A.

She has remained seizure-free but has persistent delays in communication.</p><p>Paradoxical TB-IRIS is a severe immune response that causes clinical worsening of TB lesions following initiation of appropriate treatment.<span><sup>1</sup></span> Though rare, neurological symptoms from TB-IRIS develop at a median of 60 days after treatment.<span><sup>1, 2</sup></span> Imaging classically demonstrates tuberculomas and/or meningitis. Patients are at a high risk of stroke given the tendency to develop lesions within the basal cisterns. Young children may be at higher risk of complications because their symptoms are often nonspecific (e.g., fussiness), leading to a delay in diagnosis (Figure 1).</p><p><b>Alexandria E.
