While the benefits of regular participation in physical activity for children are clear, misconceptions have developed about the possible benefits and potential complications of exercise in children with epilepsy, resulting in excessive restrictions on their sporting activities.Current evidence suggests that physical activity can not only reduce seizure frequency, but also reduce obesity and improve cognitive function and mental health.While further research is required to investigate the specific benefits of physical activity on children with epilepsy, in general, children with epilepsy should be advised to increase participation in sports and exercise as a means of improving long-term physical and mental health.This review focuses on the current situation, assessment tools, influencing factors, and benefits associated with physical activity in children with epilepsy, as well as exercise suggestions and considerations, in order to provide a reference and basis for the investigation of physical activity in children with epilepsy in China.

Graves′ disease (GD) is the most prevalent cause of hyperthyroidism in children, posing a significant threat to their normal growth and development.The incidence of GD is increasing year by year.Antithyroid drugs are the preferred treatment for GD in children, which can alleviate immune disorders and normalize thyroid function in a short period of time.However, there are still numerous unsolved problems and controversies surrounding this treatment, and the challenges that need to be overcome include the low remission rate, high recurrence rate and high incidence of adverse reactions.The key challenges facing antithyroid drug therapy are how to normalize thyroid function quickly, maintain therapeutic efficacy and reduce recurrence rate, and further studies are needed to improve the effectiveness and safety of the therapy.This article summarizes and reviews the therapeutic strategies, controversies and adverse reactions of antithyroid drugs for GD in children and adolescents.

Group A Streptococcus (GAS) are important human pathogens.In recent years, the M1 UK strain has attracted widespread attention in the United Kingdom and other countries because it has been associated with a surge in scarlet fever and an increase in invasive GAS infections.Author conducted a whole-genome sequencing study of 42 GAS strains from 2016 to 2018 in Shenzhen, and found that a GAS strain isolated from a child with scarlet fever in Shenzhen area in 2018 was homologous to M1 UK, which is the first strain of M1 UK confirmed in the mainland of China.For this reason, hereby publish it with a view to attracting the attention of our domestic counterparts and safeguarding public health safety.

Onconephrology is a new subject field that has emerged in the past decade.On the one hand, tumors can cause renal injury.On the other hand, as the research on the pathogenesis of tumors has brought unprecedented progress in tumor treatment, more treatment-related renal damage has occurred.Tumor-associated acute kidney injury is common in pediatrics.Therefore, early diagnosis and treatment are crucial for the protection and prognosis of kidney in children.This article reviews the epidemiological characteristics of pediatric cancer and the concept and pathogenesis of tumor-associated renal injury, so as to better promote the development of the field of pediatric onconephrology.

Lung diffusing capacity tests can assess the gas exchange function of the alveolar capillary membrane.With the widespread implementation of pulmonary function tests in children and the continuous improvement of testing techniques, the number of diffusing capacity tests in children has been increasing.However, there are currently no guidelines or consensuses available.This consensus provides a detailed explanation of the principles, methods, indications, contraindications, result interpretation, and clinical application of lung diffusing capacity tests in children, in order to help standardize the operation and rational application of these tests in clinical practice.

Cardiopulmonary exercise testing (CPET) is a comprehensive assessment method that evaluates the functional reserve and impairment of the respiratory, circulatory, metabolic, and musculoskeletal systems.Currently, CPET is widely used in adult medical and surgical diseases and rehabilitation therapy, and its application in pediatric diseases is also increasing.However, there are no technical standards and application guidelines for CPET in children in China.To promote the standardized application of CPET in pediatric respiratory diseases, this consensus provides a detailed description of the working principles and definitions of CPET, its indications and contraindications in pediatric respiratory systems, pre-test preparation, operation procedures, main parameters and clinical significance, report content, key points for report interpretation, and its application in respiratory diseases, and offers relevant suggestions.

Congenital heart disease (CHD) is one of the leading causes of heart failure (HF) in pediatrics.In 2024, the American Heart Association, based on existing knowledge and research findings, issued its first scientific statement on the assessment and management of HF in children and adolescents with CHD.The statement emphasizes the current lack of understanding of the epidemiology, pathophysiology, staging, and outcomes of chronic HF in pediatrics with CHD, and calls for the development of standardized definitions, monitoring protocols, and treatment strategies to improve the clinical outcomes and quality of life for this population.This article interprets the main content of the statement, aiming to provide reference and guidance for the accurate assessment and comprehensive management of chronic HF in children and adolescents with CHD.

Attention deficit hyperactivity disorder is a common neurodevelopmental disorder characterized by persistent attention deficit, hyperactivity, and impulsive behaviors that are not consistent with developmental age.Academic and vocational difficulties, social exclusion, and delinquent behaviors are manifested in daily life.It is also commonly accompanied by psychiatric problems.At the same time, mental problems are common, and the overall quality of life is greatly affected, placing a heavy burden on society as well as the family.International attention deficit hyperactivity disorder experts have developed a common and comprehensive International Classification of Functioning, Disability and Health core set of classifications for assessing individual functioning in attention deficit hyperactivity disorder.

Objective:To study the localization value of stereoelectroencephalography (SEEG) in refractory epilepsy associated with tuberous sclerosis complex (TSC), and to analyze the prognosis related factors.Methods:A case control study.Data of 66 patients with TSC-related refractory epilepsy who underwent SEEG placement at the Epilepsy Center of Tsinghua University Yu-Quan Hospital from January 2014 to March 2023 were retrospectively analyzed, including medical history, seizure semiology, scalp electroencephalogram (EEG), imaging, and SEEG findings.Patients were divided into a seizure-free group and a seizure group according to the seizures after surgery. t/ χ2 test was used to compare the relationship between age of onset, age of surgery, duration of epilepsy, genetic findings, seizure symptoms, scalp EEG characteristics, SEEG placement protocol and prognosis. Results:A total of 66 patients met the enrollment criteria, of whom 55 patients were seizure-free after surgery (seizure-free group), and 11 patients still had seizures (seizure group).Among the 66 patients, there were 46 males and 20 females; the age of onset was (21.72±30.01) months; the age of SEEG surgery was (6.79±5.12) years; the duration of epilepsy was (4.98±4.11) years.SEEG results showed that seizures started with a single tuber in 43 patients (64.4%), seizures started with 2 or more tubers in one hemisphere in 16 patients, and 7 patients had bilateral multi-tubers or the pathogenic tuber(s) could not be identified.The following factors were found to be associated with prognosis: early age of surgery ( t=-3.463, P<0.01), ictal scalp EEG with a definite lateralization ( χ2=7.876, P<0.05), and the concordance of interictal and ictal EEG ( χ2=6.821, P<0.05).The age of onset, duration of epilepsy, seizure type and symptom, genetic findings, and SEEG placement protocol were not significantly correlated with prognosis.The results of SEEG identified that onset with a single tuber revealed a better postoperative outcome. Conclusions:This study confirms the safety and efficacy of SEEG in TSC-related refractory epilepsy, and also finds that ictal EEG is uniquely valuable in guiding SEEG placement for TSC-related refractory epilepsy, which can help us better select patients with TSC-related refractory epilepsy who are suitable for SEEG placement.
