Establishment of the normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province / 中华实用儿科临床杂志

Objective:To establish the normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province.Methods:A prospective study was conducted on healthy Han-nationality children aged 3-12 who took physical examination in Wuhan Children′s Hospital, Hubei province from January to August 2021.The children were asked for their medical histories, and those with neurological diseases, psychiatric diseases, infection, trauma, and a drug history in the past 2 weeks were excluded.The plasma of 324 children (262 males, 62 females; 217 cases in the 3-7 years old, 107 cases in the 8-12 years old) and urine of 391 children (302 males, 89 females; 266 cases in the 3-7 years old, 125 cases in the 8-12 years old) were collected.They ultra performance liquid chromatography-mass spectrometry multiple techniques (UPLC-MS/MS) were used to detect 10 kinds of neurotransmitters (e.g., dopamine, epinephrine, glutamic acid, etc.) in plasma and 8 kinds of neurotransmitters (e.g., dopamine, epinephrine, 5-hydroxyindoleacetic acid, etc.) in random urine.The normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province was established.The Kruskal- Wallis H test was made for statistical analysis of the differences in neurotransmitter levels among different age groups and gender groups.The neurotransmitter levels between different groups were compared by the Nemenyi test. Results:There were no significant differences in the levels of various neurotransmitters in children of different genders(all P>0.05). There were significant differences in the levels of dopamine, methoxy-norepinephrine, tryptophan and γ-aminobutyric acid in the plasma of children aged 3-7 years and 8-12 years.There were significant differences in the levels of dopamine, epinephrine, norepinephrine, methoxy-norepinephrine, high vanillic acid and 5-hydroxyindoleacetic acid in the random urine between the 3-7 years old group and the 8-12 years old group. Conclusions:The normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province is established.This study provides reference for clinical practice and lays a foundation for the study of neurotransmitter-related diseases in children.

Fever, unilateral convulsion status, disturbance of consciousness / 中华实用儿科临床杂志

There was a 6-years-old girl who was hospitalized for " four episodes of convulsions within four hours" . On admission, the main manifestations of the patient were unilateral convulsion status, fever and disturbance of consciousness.After improvement of consciousness, physical examination revealed hemiplegia on the convulsive side.Viral encephalitis was considered at admission.However, there were no abnormalities in routine and biochemical examinations of cerebrospinal fluid(CSF), and there were no abnormalities in immune antibodies and pathogen high-throughput sequencing of CSF, which excluded central nervous system infection.According to the craniocerebral magnetic resonance imaging, extensive edema in the right cerebral hemisphere was demonstrated.Diagnosis was considered to be idiopathic hemiconvulsion hemiplegia syndrome(IHHS). The antiepileptic drug was adjusted as phenobarbital, and the seizures were reduced.But one month later, intractable epilepsy occurred, and the final diagnosis was idiopathic hemiconvulsion-hemiplegia-epilepsy syndrome(IHHES). The clinical manifestations were fever, unilateral convulsion status, and disturbance of consciousness.The diagnosis should be combined with CSF examination and imaging characteristics and other considerations.IHHS may develop to IHHES in the later stage.

Fever,poor response, convulsions, and hepatomegaly / 中华实用儿科临床杂志

Objective To investigate the differential diagnosis of Reye syndrome and the characteristics of primary carnitine deficiency,and to provide diagnostic strategy for similar cases.Methods There was a case presented with fever,poor response,convulsions and hepatomegaly hospitalized in Wuhan Children's Hospital,and the clinical manifestations were described,the physical examination was comprehensively conducted,the auxiliary examination results were recorded,some pediatric specialists from ICU,neurology department,genetic metabolic department,digestive system department were invited to discuss the case.The treatment was adjusted according to the suggested opinions;the treatment effects and the final diagnosis were tracked.Results The primary diagnosis of the case was central nervous system infection or toxic encephalopathy at the time of admission,but Reye syndrome could not be excluded.Although the cerebrospinal fluid test and brain MRI examination detected nothing abnormal,liver function suggested alanine aminotrans ferase ALT increase,blood sugar decrease,the liver volume increase,which was detected by liver ultrasound.Blood amino acids examination revealed the carnitine level decreased,and it was confirmed as primary carnitine deficiency in the end.L-carnitine was used to treat the disease,and its effect was good.Conclusions Great importance should be attached to children with onset age,physical check-up,and multidisciplinary cooperation.Use monism to explain the illness and the auxiliary inspection as far as possible,so that it can get early diagnosis and treatment,and the outcome is good.
