Neuropsychiatric SLE (NPSLE) comprises the neurologic and psychiatric syndromes observed in patients with SLE after exclusion of other causes. The diagnosis of NPSLE is challenging due to diverse clinical manifestations and absence of laboratory or radiologic biomarkers.

We present the case of a patient with SLE with a chronic isolated seizure and was successfully managed with antiepileptic medication and high-dose corticosteroids.

Seizures may occur as an isolated manifestation of an SLE flare. Ischemic and inflammatory causes of seizure may coexist in active lupus and both should be considered in managing patients. A prompt and holistic workup to rule out metabolic, infectious, and structural neural causes and lupus disease activity of seizures is prudent for patients with SLE.

The occurrence of seizures after hemorrhagic stroke is a significant contributor to mortality in patients with hemorrhagic stroke. Compared with ischemic stroke， hemorrhagic stroke is more frequently to cause seizures， with high disability and high mortality. If not detected early and treated in time， seizures may aggravate patient’s conditions in the acute stage， and cause accidental injuries in the recovery stage， increasing the burden on patient’s family. Early prediction and timely treatment of seizures can improve the survival rate and quality of life of patients. With science and technology advances， domestic and international researchers have established prediction models for seizures after hemorrhagic stroke， which use machine learning methods to process and identify relevant data， improving the accuracy of prediction for the disease. This review aims to summarize risk factors for post-hemorrhagic stroke seizures and related prediction models， so as to provide guidance for clinical diagnosis and treatment.

BACKGROUND AND OBJECTIVE

Benign convulsions with mild gastroenteritis (CwG) is common but not readily recognizable to primary care physicians and pediatricians. Most literature comes from East Asia and Western countries. Studies among the Filipino population are lacking. This study aimed to determine the clinical presentation, management, and outcomes, and provide knowledge for accurate diagnosis and appropriate management.

This is a retrospective cohort study on pediatric patients diagnosed with CwG admitted at a tertiary hospital in the Philippines from January 2020 to December 2023. The study included patients 1-72 months old presenting with seizures accompanied by symptoms of gastroenteritis, without clinical signs of dehydration, electrolyte derangement, and fever (body temperatureRESULTS

Twenty patients met the criteria for CwG, aged 7-60 months, with a male:female ratio of 1:1. Most seizures were brief, generalized tonic-clonic occurring in clusters, with an average frequency of 3 per day. Laboratory findings, electroencephalogram, and neuroimaging results were mostly normal. Anti-seizure medications (ASMs) were prescribed in 65% (n=13), with levetiracetam being the most common. Most seizure clusters did not persist, and none needed additional ASM. Follow-up showed normal neurodevelopmental profiles.

This study highlights that CwG is also encountered among Filipino children. The clinical characteristics align with the known presentation of CwG. Most patients had normal test results and a benign course. Given this selflimiting nature, extensive testing and unnecessary therapy are not recommended, and instead provision of adequate counseling to the caregivers is advocated.

Psychogenic non-epileptic seizures are accompanied by motor,behavioral,sensory,and/or cognitive changes,with the clinical manifestations similar to epileptic seizures.This disease is easy to be misdiagnosed and neglected in clinical work.At present,most intervention measures still depend on the experience of clinicians.This article reviews the comorbidities of psychogenic non-epileptic seizures,including mental and cognitive disorders,somatic syndrome,sleep disorders,and epilepsy.This review aims to strengthen the precision of clinical treatment and management of patients with psychogenic non-epileptic seizures and provide more efficient individualized diagnosis and treatment programs for patients.

OBJECTIVE: To explore the genetic etiology of a child with Spastic paraplegia and psychomotor retardation with or without seizures (SPPRS). METHODS: A child who was admitted to the Children's Hospital Affiliated to Nanjing Medical University in April 2022 for motor developmental delay, intellectual disability, and hypertonia was selected as the study subject. Relevant clinical data were retrospectively analyzed. Whole exome sequencing (WES) was carried out for the child and his parents. Candidate variants were searched in the Single Nucleotide Polymorphism Database (dbSNP) and Online Mendelian Inheritance in Man (OMIM) database. Pathogenicity of the variants was assessed based on guidelines from the American College of Medical Genetics and Genomics (ACMG). Using key words such as "HACE1 gene" "Spastic paraplegia and psychomotor retardation with or without seizures" and "SPPRS", previous reports on SPPRS patients due to HACE1 gene variants were retrieved from the CNKI, Wanfang Data Knowledge Service Platform, CQVIP, and PubMed databases, with the time set from January 1, 2000 to April 7, 2024. A mutation map for the HACE1 protein in the patients was created. This study was approved by the Ethics Committee of the Children's Hospital Affiliated to Nanjing Medical University (Ethics No. 202404008-1). RESULTS: The clinical manifestations of the child had included motor developmental delay, intellectual disability and hypertonia. Magnetic resonance imaging revealed hypoplasia of posterior corpus callosum and splenium, with slight enlargement of lateral ventricles. WES revealed that the child has harbored compound heterozygous variants of the HACE1 gene, namely c.535(exon7)_c.538(exon7)delACAG (p.T179fs*5) and c.1678+2(IVS15)T>C, which were respectively inherited from his parents. Based on the guidelines from the ACMG, the variants were respectively rated as likely pathogenic (PVS1 + PM2_Supporting) and pathogenic (PVS1 + PM2_Supporting + PM3). Literature search has identified 8 papers, which reported 23 SPPRS cases due to HACE1 gene variants. All patients exhibited psychomotor developmental delay, among whom 18 HACE1 gene variants were identified. CONCLUSION The c.535(exon7)_c.538(exon7)delACAG (p.T179fs*5) and c.1678+2(IVS15)T>C compound heterozygous variants of the HACE1 gene probably underlay the pathogenesis of SPPRS in this child. Above discovery has enriched the mutational and phenotypic spectrum of the HACE1 gene and provided a reference for clinical diagnosis and genetic counseling.

OBJECTIVE: To analyze the clinical characteristics and genetic etiology of a child with Christianson syndrome (CS). METHODS: A 1-year-and-5-month-old boy with CS diagnosed at the First Affiliated Hospital of Zhengzhou University in April 2021 was selected as the study subject. Clinical data were retrospectively analyzed. Peripheral blood samples were obtained from the child and his parents, followed by genomic DNA extraction and whole exome sequencing (WES). Candidate variant was validated by Sanger sequencing. This study has been approved by the Medical Ethics Committee of the Hospital of Zhengzhou University (Ethics No. 2024-KY-1103-001). RESULTS: The child has manifested with seizures, microcephaly, and global developmental delay. WES revealed that he has harbored a novel de novo hemizygous nonsense variant of the SLC9A6 gene, namely c.1014G>A (p.W338*). Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic. CONCLUSION The hemizygous c.1014G>A nonsense variant of the SLC9A6 gene probably underlay the pathogenesis in this child. Above discovery has expanded mutational spectrum of the SLC9A6 gene and enabled definite diagnosis of the child.

OBJECTIVE: To explore the clinical characteristics and genetic cause of a child with gastrointestinal hemorrhage and Cerebroretinal microangiopathy with calcifications and cysts (CRMCC) and to review the literature. METHODS: Clinical data of a child with gastrointestinal hemorrhage with CRMCC admitted to the Hepatology Department of Hunan Children's Hospital in September 2019 were collected, and peripheral blood DNA of the child and his parents were analyzed by whole exome sequencing. Candidate variants were validated by Sanger sequencing, followed by bioinformatics analysis, American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants pathogenicity classification, and protein structure prediction. A literature search with "Coats Plus syndrome" or "Cerebroretinal microangiopathy with calcifications and cysts" as keywords was conducted at PubMed, China National Knowledge Infrastructure and Wanfang databases to include recently published studies (up to December 2023). This study has been approved by the Ethics Committee of Hunan Children's Hospital (Ethics No. KY2020-07). Informed consent for clinical research was obtained from the guardian of the child. RESULTS: The proband was a 10-year-10-month-old boy. The clinical manifestations were intrauterine and postnatal growth retardation, gastrointestinal hemorrhage, liver fibrosis, panhemopenia, bilateral exudative retinopathy, intracranial lesions and facial pigmentation. WES and Sanger sequencing revealed two novel heterozygous variants in the CTC1 gene: c.787G>A (p.Val263Met) in exon 5 and c.2930C>G (p.Ser977Cys) in exon 17, which were inherited from his mother and father, respectively. According to ACMG pathogenicity classification, both missense variants were classified as variants of uncertain significance (VUS). Protein structure prediction showed the absence of LIG_SH3_3 motif and LIG_SH3_3 motif, and the p.Ser977Cys mutation may affect the binding between CST (CTC1-STN1-TEN) complex and DNA strand. The child had continued to experience recurrent gastrointestinal bleeding episodes despite propranolol treatment, but the condition was controlled after liver transplantation. According to the predefined literature search strategy of this study, a total of 10 relevant articles on pediatric CRMCC patients were retrieved, involving 11 children with gastrointestinal bleeding. Pharmacological and endoscopic therapies play a certain role in the management of CRMCC children complicated with gastrointestinal bleeding. CONCLUSION The CTC1 gene c.787G>A and c.2930C>G variants probably underlay CRMCC in this child. This study has broadened the variation spectrum of CTC1-related diseases and provided a basis for genetic counseling. Liver transplantation may be an important treatment for gastrointestinal hemorrhage in children who do not respond well to medication and endoscopic therapy.

OBJECTIVE: To investigate the clinical and genetic characteristics of a Chinese pedigree affected with Neurodevelopmental disorder with absent language and variable seizures (NEDALVS) due to variant of WASF1 gene, and to review the literature on NEDALVS associated with WASF1 gene variants. METHODS: A 4-year-and-8-month-old boy with NEDALVS diagnosed at Linyi People's Hospital in July 2024 due to "discovering language development delay for more than 2 years" and his family members were selected as the study subjects. Clinical data of the family members were collected. Peripheral venous blood samples were collected from family members. Whole-exome sequencing (WES) was performed, and candidate variants were verified, by Sanger sequencing. Pathogenicity of candidate variant was classified according to the Standards and Guidelines for the Interpretation of Sequence Variants established by the American College of Medical Genetics and Genomics (ACMG). Using the MUpro website, SWISS-MODEL, PyMOL, Clustal X, PolyPhen-2, and Mutation Taster software, bioinformatics analysis of protein three-dimensional structure modeling for gene mutations, cross-species conservation of mutant amino acids, and pathogenicity prediction of mutation sites. Relevant literature was retrieved from databases such as CNKI, Wanfang Data Knowledge Service Platform, and PubMed, and the clinical phenotypes and genotypes of patients with WASF1 gene mutations reported in the literature were summarized and analyzed. This study was approved by the Medical Ethics Committee of Linyi People's Hospital (Ethics No.: YX200303). RESULTS: The proband, a 4-year and 8-month-old male, mainly presented with delayed language and motor development, accompanied by autistic behaviors; the proband's younger brother was 2 years and 7 months old at the time of consultation, mainly presented with delayed language and motor development, accompanied by short stature; the proband's mother mainly presents with limited language expression and poor interpersonal interaction; the proband's maternal grandmother mainly presents with soliloquizing?behavior. The results of WES showed that the proband carried a heterozygous mutation c.214C>T (p.Arg72Cys) in the WASF1 gene, and this site has not been recorded in the database. Sanger sequencing confirmed that the proband's younger brother, mother, and maternal grandmother had harbored the same variant. Based on the guidelines from the ACMG, this variant was rated as likely pathogenic (PM2_Supporting+PP1+PP3+PP4). Through SWISS-MODEL homology modeling and PyMOL structure visualization analysis, it was further confirmed that this variant can lead to a decrease in protein stability. Amino acid sequence conservation analysis of the WASF1 protein using Clustal X software suggested that the c.214C>T (p.Arg72Cys) variant has caused replacement of a highly conserved amino acid. According to the results of PolyPhen-2 and Mutation Taster, the p.Arg72Cys variant was predicted to be a hazardous. By following the retrieval strategy set in this study, a total of 5 research articles regarding to patients with NEDALVS caused by WASF1 gene mutations were retrieved, which involved 15 patients. Combining the proband and their family members discovered in this study, there were a total of 19 NEDALVS patients. The main clinical features included: motor developmental delay (100%, 17/17), language/intellectual developmental delay (100%, 17/17), epilepsy (64.7%, 11/17), autistic behavior (76.5%, 13/17), hypotonia (70.6%, 12/17), abnormal electroencephalogram (64.7%, 11/17), and short stature (17.6%, 3/17). All 19 patients had heterozygous mutations, with 8 mutation sites. Missense mutations were the most common, accounting for 84.2% (16/19). CONCLUSION A pathogenic variant of the WASF1 gene was identified in a pedigree affected with NEDALVS. Discovery of the novel variant has, expanded the mutational spectrum of the WASF1 gene.

OBJECTIVE: To explore the clinical and genetic characteristics of a child with intellectual development disorder and seizures due to a variant of AP2M1 gene. METHODS: Clinical data of a child with intellectual development disorder and epilepsy who was admitted to the Department of Pediatric Neurology of the Third Affiliated Hospital of Zhengzhou University in January 2021 were retrospectively analyzed. Peripheral blood samples of the child and his parents were collected for whole exome sequencing. Candidate variant was verified by Sanger sequencing and pathogenicity analysis. The three-dimensional structure of the AP2M1 protein was visualized using Chimera v1.10.1 software. Pathogenicity of candidate variant was classified according to the Standards and Guidelines for the Interpretation of Sequence Variants from the American College of Medical Genetics and Genomics American College of Medical Genetics (ACMG). With "AP2M1 gene" "epilepsy" "intellectual disability" as the keywords, relevant cases were searched from CNKI, Wanfang Data knowledge service platform and PubMed databases with the search time spanning from the establishment of the database to September 2024. This study was approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethics No.: 2020-57). RESULTS: The child was a 8-years-and-6-months-old boy, who could raise his head at 3 months and sit alone at 8 months old. He could not walk alone at 1 year old and underwent 2 months' rehabilitation treatment, and could walk alone and call his parents at 1-and-a-half-years-old. At 4-years-and-10-months-old, he started to have frequent seizures, manifesting as low level of consciousness, body shaking, accompanied by blinking, lasting about a few seconds several times a day and could be relieved. With the treatment of sodium valproate combined with lamotrigine, the convulsions were controlled, but his movement and cognition were lagged behind. DNA sequencing revealed that he has harbored a novel variant of the AP2M1 gene (NM_004068.3) c.508C>T (p.Arg170Trp). Sanger sequencing confirmed that both of his parents were of the wild-type. According to the guidelines from the American College for Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PS2+PS4+PM1+PM2+PP2+PP3). The difference between the wild-type and mutant AP2M1 proteins can be clearly viewed through its three-dimensional structure. Two previous reports have included 5 cases due to the same variant. Common manifestations have included seizures (100%, 5/5), motor retardation (100%, 5/5), intellectual impairment (100%, 5/5), autism spectrum disorder (60%, 3/5), ataxia (100%, 5/5), and special facial features (20%, 1/5). CONCLUSION The c.508C>T (p.Arg170Trp) variant of the AP2M1 gene may underlie the intellectual retardation and seizure in this child.

Neuropsychiatric SLE (NPSLE) comprises the neurologic and psychiatric syndromes observed in patients with SLE after exclusion of other causes. The diagnosis of NPSLE is challenging due to diverse clinical manifestations and absence of laboratory or radiologic biomarkers.

We present the case of a patient with SLE with a chronic isolated seizure and was successfully managed with antiepileptic medication and high-dose corticosteroids.

Seizures may occur as an isolated manifestation of an SLE flare. Ischemic and inflammatory causes of seizure may coexist in active lupus and both should be considered in managing patients. A prompt and holistic workup to rule out metabolic, infectious, and structural neural causes and lupus disease activity of seizures is prudent for patients with SLE.
