OBJECTIVES: To examine the association between duration of fever before intravenous immunoglobulin (IVIG) treatment and IVIG resistance in children with Kawasaki disease (KD). METHODS: A retrospective analysis was performed on the medical data of 317 children with KD who were admitted from January 2018 to December 2020. According to the duration of fever before IVIG treatment, they were divided into two groups: short fever duration group (≤4 days) with 92 children and long fever duration group (>4 days) with 225 children. According to the presence or absence of IVIG resistance, each group was further divided into a drug-resistance group and a non-drug-resistance group. Baseline data and laboratory results were compared between groups. A multivariate logistic regression analysis was used to identify the influencing factors for IVIG resistance. RESULTS: In the short fever duration group, 19 children (20.7%) had IVIG resistance and 5 children (5.4%) had coronary artery aneurysm, and in the long fever duration group, 22 children (9.8%) had IVIG resistance and 19 children (8.4%) had coronary artery aneurysm, suggesting that the short fever duration group had a significantly higher rate of IVIG resistance than the long fever duration group (P<0.05), while there was no significant difference in the incidence rate of coronary artery aneurysm between the two groups (P>0.05). In the short fever duration group, compared with the children without drug resistance, the children with drug resistance had a significantly lower level of blood sodium and significantly higher levels of procalcitonin, C-reactive protein, and N-terminal B-type natriuretic peptide before treatment (P<0.05). In the long fever duration group, the children with drug resistance had significantly lower levels of blood sodium and creatine kinase before treatment than those without drug resistance (P<0.05). The multivariate logistic regression analysis showed that a reduction in blood sodium level was associated with IVIG resistance in the long fever duration group (P<0.05). CONCLUSIONS IVIG resistance in children with KD varies with the duration of fever before treatment. A reduction in blood sodium is associated with IVIG resistance in KD children with a duration of fever of >4 days before treatment.

OBJECTIVE: To explore the availability of transcatheter closure of atrial septal defect(ASD)in infants guided by transesophageal echocardiography(TEE). METHODS: The clinical data of 13 infants(under one year old)with ASD who underwent transcatheter closure via right jugular vein through adjustable curved sheath under guidance of TEE from June 2015 to March 2018 in Qingdao Women and Children's Hospital were analyzed retrospectively. The operation effect,time and complications were evaluated. RESULTS: All 13 infants were successfully occluded. TEE can accurately guide the establishment of the delivery track. The operation time was(27.2±15.1)minutes. All patients had satisfactory occluder shape and fixed position,without such complications as arrhythmia,hemolysis,embolism,infection,pneumothorax,hemothorax or vessel injury.CONCLUSION: TEE-guided transjugular closure of ASD is a feasible method,which can avoid surgical risks and vessel complications in young and low-bodyweight infants;Meanwhile,the potential radiation damage can be avoided.

Pulmonary artery denervation (PADN) can block local sympathetic nerve of pulmonary artery, reduce the hemodynamic parameters of pulmonary arterial hypertension(PAH), attenuate pulmonary vascular remodeling, right ventricular hypertrophy and fibrosis, thus improving cardiac function.Early basic experiment has determined the position of sympathetic nerve of pulmonary artery in pulmonary endarterium and confirmed the safety and effectiveness of PADN in the animal model of PAH.PADN may play a role by inhibiting execssive activation of the sympathetic nervous system and renin-angiotension-aldosterone system.PADN has been applied to adult clinical research, and has achieved a good clinical effect.On this basis, the possibility of applying PADN to children′s PAH is being explored preliminarily.

OBJECTIVE: To evaluate the application of MSCT and post-processing images to fractures of nasal bone in forensic identification. METHODS: 134 cases were examined by thin slice scanning with MSCT and all of the data were sent to workstation for MPR and SSD. The result of MSCT was compared with that of X-ray. RESULTS: There are 55 (41.04%) cases of linear fracture, 46 (34.33%) cases of comminuted fracture, 27 (20.15%) cases of depressed fracture and 6 (4.48%) cases of no fracture in this sample. With X-ray or CR, 48 (35.82%) cases were misdiagnosed or underdiagnosed. 133 (99.25%) cases were confirmed by MSCT. Significance difference was found between X-ray and MSCT (chi2= 45.0816, P<0.001). CONCLUSION MSCT and post-processing images might be the chief evidence for nasal fractures in forensic identification.

Emotional disorder is one of the main clinical symptoms of autism spectrum disorder(ASD),which is related to the lack of emotional awareness,social cognition and alexithymia. It is often manifested as difficulty in recognizing,distinguishing and processing emotional information of oneself and others,resulting in making inappropriate emotional reactions. Children and adolescents with ASD often participate in school bullying as the perpetrator,victim,or victim-perpetrator,and this brings about a series of negative physical and mental effects on them. Bullying prevention should not only include interventions for core symptoms and comorbidities of ASD,but also involve building partner empathy and social skills,teacher responsibility and supportive services,parental involvement,and social integration.

OBJECTIVE: To summarize the experience of percutaneous balloon pulmonary valvuloplasty for pulmonary stenosis in infants,and to evaluate its necessity,safety and effectiveness. METHODS: From January 2009 to December2018,68 cases of pulmonary stenosis were treated by percutaneous balloon pulmonary valvuloplasty. The clinical data before and after operation were analyzed retrospectively. RESULTS: The mean age was(6.34±3.6)months. The mean operation weight was(7.81±2.11)kg. The preoperative body weight/age Z score was-0.80±1.38,and growth restriction was in 22 cases(32.4%),cyanosis in 15 cases(22.1%)and tachypnea in 23 cases(33.8%). The mean right ventricular/left ventricular length-diameter ratio was 0.56±0.73 by echocardiography,the mean cardiothoracic ratio was 0.56±0.43 by chest radiography,and the average value of preoperative oxygen saturation was 94.74 ± 6.10. The mean systolic pressure ratio of right ventricle/left ventricle before operation was 0.68±0.26. After balloon dilation,the mean pressure gradient of pulmonary valve decreased from(75.57 ± 18.61)mmHg to(22.37 ± 5.21)mmHg,and the mean systolic pressure of right ventricle decreased from(83.78±22.44)mmHg to(54.16±20.81)mmHg. The immediate success rate of operation was 100%. There were no serious arrhythmia,cardiac perforation,rupture of tendon chordae,vascular injury or other complications during the operation. The proportion of mild to moderate pulmonary regurgitation was 53.3% in early stage after operation,and there was no severe regurgitation. The restenosis rate was 2.94% during the follow-up period of 3 months to 10 years. The pulmonary valve regurgitation degree of 32 children who were followed up for more than 5 years did not further aggravate,and no specific management was carried out. No obvious right ventricular dysfunction was found in all patients. Compared with the toddlerhood infants undergoing PBPV in our center,the babyhood infants had obvious clinical symptoms and serious condition. The early and medium-long-term follow-up after operation was satisfactory. There was no significant difference in the effect of operation in the low-weight or low-age infants in babyhood. CONCLUSION: PBPV is necessary for the treatment of pulmonary stenosis in infants. The technique is safe and feasible,and the follow-up results are effective.

Intravascular foreign bodies (IFB), most being iatrogenic foreign bodies, have become common clinical problems because of their adverse effect such as thrombogenesis, which may affect the function of important organs and even lead to death in some serious cases. It is necessary to remove IFB out in time. Percutaneous vascular intervention technologies have been widely used to remove IFB in recent years. The advancements of percutaneous vascular intervention technologies in application of removal IFB were reviewed in this article.

OBJECTIVE: To study the clinical features of children with recurrent Kawasaki disease (KD). METHODS: PubMed, Web of Science, Embase, CNKI, Wanfang Med Online, and Weipu Data were searched for case-control studies on the clinical features of initial and recurrent KD. The articles were screened according to the inclusion and exclusion criteria. RevMan 5.3 software was used to perform the Meta analysis. Effect models were selected based on the results of heterogeneity test, and then pooled RESULTS: A total of 9 case-control studies were included, with 12 059 children with KD in total, among whom 206 children had recurrent KD (127 boys/61.7%; 79 girls/38.3%). The results of the Meta analysis showed that compared with the initial KD onset, the children with recurrent KD had a shorter duration of fever ( CONCLUSIONS Current evidence shows that children with recurrent KD tend to have a shorter duration of fever and a lower incidence of swelling of the hands and feet. KD recurrence is more common in boys. Current evidence does not show an increased risk of developing coronary artery lesions in children with recurrent KD.

OBJECTIVES: To evaluate the clinical effectiveness of integrated management during the perinatal period for fetuses diagnosed with total anomalous pulmonary venous connection (TAPVC) by prenatal echocardiography. METHODS: Clinical data of 64 cases of TAPVC fetuses diagnosed by prenatal echocardiography and managed with integrated perinatal care in Qingdao Women and Children's Hospital from January 2017 to December 2021 were retrospectively analyzed. Integrated perinatal care included multidisciplinary collaboration among obstetrics, fetal medicine, ultrasound, pediatric cardiology, pediatric anesthesia, and neonatology. RESULTS: Among the 64 TAPVC fetuses, there were 29 cases of supracardiac type, 27 cases of intracardiac type, 2 cases of infracardiac type, and 6 cases of mixed type. Chromosomal analysis was performed in 42 cases, and no obvious abnormalities were found. Among the 64 TAPVC fetuses, 37 were induced labor, and 27 were followed up until term birth. Among the 27 TAPVC cases, 2 cases accepted palliative care, 2 cases were referred to another hospital for treatment and lost to follow-up, while the remaining 23 cases underwent primary repair surgery. One case died within 6 months after the operation due to low cardiac output syndrome, while the other 22 cases were followed up for (2.1±0.3) years with good outcomes (2 cases underwent a second surgery within 1 year after the first operation due to anastomotic stenosis or pulmonary vein stenosis). CONCLUSIONS TAPVC fetuses can achieve good outcomes with integrated management during the perinatal period.
