Clinical features of children with febrile seizures caused by Omicron variant infection / 中国当代儿科杂志

OBJECTIVES@#To study the clinical features of children with febrile seizures after Omicron variant infection.@*METHODS@#A retrospective analysis was performed on the clinical data of children with febrile seizures after Omicron variant infection who were admitted to the Department of Neurology, Children's Hospital Affiliated to the Capital Institute of Pediatrics, from December 1 to 31, 2022 (during the epidemic of Omicron variant; Omicron group), and the children with febrile seizures (without Omicron variant infection) who were admitted from December 1 to 31, in 2021 were included as the non-Omicron group. Clinical features were compared between the two groups.@*RESULTS@#There were 381 children in the Omicron group (250 boys and 131 girls), with a mean age of (3.2±2.4) years. There were 112 children in the non-Omicron group (72 boys and 40 girls), with a mean age of (3.5±1.8) years. The number of children in the Omicron group was 3.4 times that in the non-Omicron group. The proportion of children in two age groups, aged 1 to <2 years and 6-10.83 years, in the Omicron group was higher than that in the non-Omicron group, while the proportion of children in two age groups, aged 4 to <5 years and 5 to <6 years, was lower in the Omicron group than that in the non-Omicron group (P<0.05).The Omicron group had a significantly higher proportion of children with cluster seizures and status convulsion than the non-Omicron group (P<0.05). Among the children with recurrence of febrile seizures, the proportion of children aged 6-10.83 years in the Omicron group was higher than that in the non-Omicron group, while the proportion of children aged 3 years, 4 years, and 5 years in the Omicron group was lower than that in the non-Omicron group (P<0.05).@*CONCLUSIONS@#Children with febrile seizures after Omicron variant infection tend to have a wider age range, with an increase in the proportion of children with cluster seizures and status convulsion during the course of fever.

Clinical and electrophysiologic characteristics of anti-N-methyl-D-aspartate receptor encephalitis in children / 中华实用儿科临床杂志

Objective To explore the clinical and electrophysiologic features of anti-N-methyl-D-aspartate receptor(NMDAR) encephalitis in children.Methods The clinical records and findings of electroencephalogram(EEG) of the anti-NMDAR encephalitis patients diagnosed in the Capital Institute of Pediatrics were reviewed and analyzed.Five patients with anti-NMDAR encephalitis were identified,including 4 boys and 1 girl,aged from 2 years and 6 months to 6 years and 8 months.Results No tumor was found in those patients.Four patients developed the symptoms of seizure at first,and suffered from consciousness disturbance and movement disorder later,while the other patient was found to be affected by language disorder at first.All patients were treated with methylprednisolone and intravenous immunoglobulin therapy,and plasma exchange and (or) CD20 monoclonal antibodies were used when the patient did not respond well to the treatment.With this immunotherapy used,the patients showed great improvement in cognitive,language and movement abilities,but 1 relapsed 9 months after discharge.All patients had abnormal electroencephalogram with diffusive slow waves,and some with focal spikes or sharp waves.After the patients recovered,EEG showed fewer slow waves,and even normal backgrounds.Conclusions Anti-NMDAR encephalitis can be found in children,even young boys may be affected by it without tumors.For those suffering from this disease,seizure and language disorder may be one of the initial symptoms,and movement disorder and consciousness alteration will occur later.In treating this disease,immunotherapy proves effective.There is a risk of disease relapse if the immune treatment doesn't sustain long enough.

Study Progress on Detection Technique and Treatment of Inheirted Metabolic Disorders / 实用儿科临床杂志

Inheirted metabolic disodrers(IMD)involves in multiple substance dysbolism,which usually results in irreversible neurological lesions because of various categories and complicated clinical manifestations.In resent years,IMD became one of the hot spots in medical domain around the world,original diagnostic technique and management progressed unceasingly.This paper provides an overview of the traditio-nal detection and treatment about IMD,and reviews the new techniques such as gene analysis,gene chip,organ transplantation and enzyme replacement therapy at the same time.
