ObjectiveTo systematically review the protective effect of serum maternal respiratory syncytial virus (RSV) antibodies on infants with RSV infection. MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang Data databases were electronically searched to collect observational studies on the correlation between serum maternal RSV antibodies and infants with RSV infection from inception to July 18, 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies, then, qualitative analysis was performed. ResultsA total of 19 studies were included, and 60% of those studies suggested that a higher level of maternal antibodies could prevent RSV infection. However, the remaining 40% of them showed that there was no significant difference in the level of RSV maternal antibodies between the infected group and the non-infected group. Further more, in the studies of the correlation between maternal antibody level and disease severity after RSV infection, 55% of those showed that maternal antibody level was negatively correlated with disease severity. ConclusionThe protective effect of serum maternal RSV antibodies on infants reported in different studies varies. Whether it can prevent RSV infection and affect the severity of RSV infected children still needs to be explored.
Objective To evaluate the effect of cardiopulmonary bypass （CPB） on pulmonary function in infants with variable pulmonary arterial pressure resulting from congenital ventricular septal defect （VSD）. Methods Twenty infants with VSD underwent corrective surgery were divided into pulmonary hypertension group （n= 10） and non-pulmonary hypertension group （n= 10） according to with pulmonary hypertension or not. Pulmonary function was measured before CPB , 3h,6h,9h,12h,15h,18h,21h, and 24h after CPB and duration for mechanical ventilation and cardiac intensive care unit stay were recorded. Results Pulmonary function parameters before CPB in nonpulmonary hypertension group were superior to those in pulmonary hypertension group （P〈0.01）, and pulmonary function parameters after CPB deteriorated than those before CPB （P〈0.05）, especially 9h,12h and 15h after CPB （P〈0.01）. Compared to pulmonary function parameters before CPB, pulmonary function parameters of pulmonary hypertension group at 3h after CPB were improved （P〉0.05）, but they deteriorated at 9h,12h and 15h after CPB （P〈0. 05）. Pulmonary function parameters at 21h and 24h after CPB was recoverd to those before CPB in two groups. Conclusions Although exposure to CPB affects pulmonary function after VSD repair in infants, the benefits of the surgical correction to patients with pulmonary hypertension outweigh the negative effects of CPB on pulmonary function. Improvement of cardiac function can avoid the nadir of pulmonary function decreasing. The infants with pulmonary hypertension will be weaned off from mechanical ventilator as soon as possible, if hemodynamics is stable, without the responsive pulmonary hypertension or pulmonary hypertension crisis after operation.
Objective To compare the changes between deep hypothermic circulatory arrest (DHCA) with deep hypothermic low flow (DHLF) cardiopulmonary bypass (CPB) on pulmonary surfactant (PS) activity in infants with congenital heart disease. Methods Twenty infants with ventricular septum defect and pulmonary hypertension were assigned to either DHCA group or DHLF group according to the CPB methods respectively. Measurements of saturated phosphatidylcholine /total phospholipids (SatPC /TPL), saturated phosphatidylcholine/ total protein (SatPC/TP) and static pulmonary compliance were performed before institution of CPB, 5 minutes after cessation of CPB and 2 hours. Results The length of ICU stay in DHLA group was significantly longer ( P lt;0 05) than that in DHCA group. SatPC/TPL, SatPC/TP and static pulmonary compliance in DHLF group were significantly lower compared with DHCA group ( P lt;0.01). Conclusion DHLF could lower the PS activity level significantly as compared with DHCA in infants with congenital heart disease.
目的 探讨婴儿急性白血病（IAL）的临床与实验室检查特征。 方法 对1999年12月－2011年6月收治的15例婴儿急性白血病的临床资料进行总结与分析。 结果 其中急性淋巴细胞白血病（ALL）6例，急性髓系白血病（AML）8例，分类不明1例，其中以M4（4例）、M5（3例）为主。临床表现多样，髓外浸润明显。1例细胞形态学与免疫分型有差异，1例合并染色体异常。放弃治疗者11例，死亡2例，正规治疗的2例于诱导缓解后获完全缓解。 结论 IAL预后差，需完善相关检查并不断总结临床资料以提高IAL治愈率。
Objective To investigate the effect of surgical treatment on ventricular septal defect （VSD） in infants under 6kg weight, including the operative indication, surgical techniques and perioperative therapy. Methods All clinical data of 148 consecutive infants under 6kg weight with VSD were collected and studied retrospectively. The infants, age was 1-13（mean 5.3） months with the body weight of 3.5-6.0 （mean 5.3） kg. VSD was perimembranous in 105 cases, subpulmonary in 25, muscular inlet tract in 8, muscular outlet tract 9, and muscular trabecular in 1 case. Other associated cardiac abnormalities included atrial septal defect in 39, patent ducts arteriosus in 17, insufficiency of mitral valve in 9 and moderate to severe pulmonary hypertension in 52. The operations were performed under cardiopulmonary bypass at moderate to low flow, moderate hypothermia and cold crystalloid cardioplegia. Patch repair was used in 85, direct sutures in 63 and 23 cases repaired with partial sternal incision and beating heart. Results The hospital mortality was 4. 1% （6/148）, the causes of death were severe pulmonary hypertention in 2, aortic arch interruption in 2, severe malnutrition in 1 and poor result of mitral valvuloplasty in 1. Other major operative complications included residual shunts （1- 2mm） in 2, and Ⅲ° A-V block in 2, who recoveried 5 days after the operation. The hospital stay was 6 15 （mean 8） days. Follow-up was complete in all 142 survived cases for 4 months-6 years. Two residual shunts healed in first year after the cardiac operation, others recovery smoothly, and are developing well. Conclusion With the improvement of the surgical techniques, the surgical treatment for VSD in infants with low weight is safe and effective, and it is also essential to further improve the effects of surgical treatment in VSD associated with complex abnormalities.
ObjectiveTo explore the clinical manifestation, diagnosis, treatment and prognosis of infantile spasm complicated with craniostenosis.MethodsA case of infantile spasm complicated with craniostenosis in the Department of Neurology of Qilu Children's Hospital in December 2017 was reviewed with the literature. The clinical manifestations, diagnosis, treatment and prognosis of infantile spasm with craniostenosis were analyzed.ResultsThe proband infantile spasms and craniostenosis was diagnosed by clinical, imaging examination and VEEG. Epileptic attack was prevented and craniostenosis was corrected by hormone shock therapy (corticotrophin was administered for 14 days, followed by topiramate)and surgical treatment (cranial cap reconstruction was performed), and good clinical prognosis was obtained.ConclusionThis case was the first reported case of craniostenosis with infantile spasm in China, and compared with the foreign treatment method, better treatment method and the operation opportunity were obtained. Which has a significant effect on the clinical treatment of infantile spasm complicated with transcranial disease.
Infantile epileptic spasm syndrome (IESS) is an age-dependent epileptic encephalopathy that onset within 3 ~ 12 months. Commonly used Anti-seizure medications (ASMs) have poor efficacy, low long-term control rate and high recurrence rate, and often leave behind sequelae such as developmental delay/intellectual disability, and autism spectrum disorders. At present, the first-line recommended treatments for IESS are Adrenocorticotropic hormone (ACTH), adrenocortical hormone and vigabatrin. If ineffective, other ASMs, ketogenic diets, and surgical treatments can be tried. This article will provide a review of the current status and related clinical applications of IESS treatment.
