Value of metagenomic next-generation sequencing in children with severe infectious diseases / 中国当代儿科杂志

OBJECTIVES@#To study the application value of metagenomic next-generation sequencing (mNGS) in children with severe infectious diseases.@*METHODS@#An analysis was performed on the clinical data and laboratory test results of 29 children with severe infection who were admitted to the Second Affiliated Hospital of Wenzhou Medical University from June 2018 to December 2020. Conventional pathogen culture was performed for the 29 specimens (27 peripheral blood specimens and 2 pleural effusion specimens) from the 29 children, and mNGS pathogen detection was performed at the same time.@*RESULTS@#Among the 29 children, 2 tested positive by conventional pathogen culture with 2 strains of pathogen, and the detection rate was 7% (2/29); however, 20 children tested positive by mNGS with 38 strains of pathogen, and the detection rate was 69% (20/29). The pathogen detection rate of mNGS was significantly higher than that of conventional pathogen culture (P<0.05), and mNGS could detect the viruses, fungi, and other special pathogens that conventional pathogen culture failed to detect, such as Orientia tsutsugamushi. The univariate analysis showed that gender, routine blood test results, C-reactive protein, procalcitonin, D-dimer, radiological findings, and whether antibiotics were used before admission did not affect the results of mNGS (P>0.05).@*CONCLUSIONS@#Compared with conventional pathogen culture, mNGS is more sensitive for pathogen detection, with fewer interference factors. Therefore, it is a better pathogenic diagnosis method for severe infectious diseases in children.

Benign infantile convulsions associated with mild gastroenteritis: a clinical analysis and follow-up study / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the clinical features and prognosis of benign infantile convulsions associated with mild gastroenteritis (BICE).</p><p><b>METHODS</b>A retrospective analysis was performed for the clinical data of 436 children with BICE, and among these children, 206 were followed up for 1.5 to 7 years. Some parents were invited to complete the Weiss Functional Defect Scale to evaluate the long-term social function.</p><p><b>RESULTS</b>The peak age of onset of BICE was 13-24 months, and BICE had a higher prevalence rate in September to February of the following year. Convulsions mainly manifested as generalized tonic-clonic seizures, which often occurred within 24 hours after disease onset and lasted for less than 5 minutes each time. Sometimes they occurred in clusters. During the follow-up of 206 children, only one had epileptiform discharge, and the other children had normal electroencephalographic results. The parents of all the 206 children thought their children had normal intelligence and had no marked changes in character. Based on the Weiss Functional Defect Scale completed by the parents of some BICE children, there was no significant difference in the long-term social function between BICE children and healthy children matched by age and sex.</p><p><b>CONCLUSIONS</b>BICE mainly occurs in children aged 1-2 years, with the manifestation of transient generalized seizures in most children and cluster seizures in some children. BICE seldom progresses to epilepsy and has good prognosis.</p>

Effects and Safety of Hemoperfusion Therapy on Infants with Tetramine Poisoning / 实用儿科临床杂志

Objective To explore the effects and safety of hemoperfusion(HP) therapy on tetramine poisoning in infants.Methods Thirty-five infants with tetramine poisoning were divided into two groups: HP group(n=18) and non HP group(n=17).The changes of blood tetramine concentration and clinical symptom improving of both groups after the treatment were observed together with the adverse effects of HP group.Results The average blood tetramine concentration of HP group was higher than that of non HP group(342.2?333.4 vs 117.9?50.8 ?g/L,P
