ObjectiveTo evaluate the effectiveness of Cross-Union surgery for the treatment of pseudarthrosis of the tibia (PT) with neurofibromatosis type 1 (NF1). MethodsThe clinical data of 8 children of PT with NF1 who met the selection criteria between January 2018 and December 2023 was retrospectively analyzed. There were 5 boys and 3 girls, and the operative age ranged from 1.8 to 13.3 years with a median age of 3.5 years. According to Paley classification, there were 2 cases of type 2a, 2 cases of type 3, 2 cases of type 4a, and 2 cases of type 4c. There were 5 cases of first operation and 3 cases of re-fracture after previous operation. Six cases had leg length discrepancy before operation, and 2 of them had shortening over 2.0 cm. Except for 1 case of ankle fusion, the other 7 cases had ankle valgus. Preoperative coronal/sagittal angulation was recorded. Postoperative pseudarthrosis healing and refracture were observed. Leg length discrepancy and tibiotalar angle were measured and recorded before operation and at last follow-up. Inan imaging evaluation criteria was used to evaluate the imaging effect. ResultsAll patients were followed up 12-37 months (mean, 23.5 months). One pseudarthrosis failed to heal at 12 months after operation and healed at 3 months after reoperation, while the other pseudarthrosis healed with a healing rate of 87.5% and a healing time of 4-8 months (mean, 5.3 months). No refracture occurred during the follow-up. At last follow-up, there were 2 new cases with leg length discrepancy, which were 0.7 cm and 1.3 cm, respectively. In 2 cases with the leg length discrepancy more than 2.0 cm before operation, the improvement was from 4.1 cm and 12.6 cm to 2.1 cm and 9.0 cm, respectively. There was no significant difference in leg length discrepancy between pre- and post-operation in 8 cases (P>0.05). At last follow-up, 6 patients still had ankle valgus, and there was no significant difference in the tibiotalar angle between pre- and post-operation (P>0.05); the tibial coronal/sagittal angulation significantly improved when compared with that before operation (P<0.05). According to Inan imaging evaluation criteria, 1 case was good, 6 cases were fair, and 1 case was poor. Conclusion Cross-Union surgery is an effective method for the treatment of PT with NF1 in children, can achieve good bone healing results with a low risk of re-fracture. The surgery may not have significant effects on leg length discrepancy and ankle valgus, and further treatment may be required.

ObjectiveTo compare the effect and safety of basiliximab in ABO incompatible pediatric liver transplant recipients.MethodsABO incompatible pediatric liver transplantation operated between January 2019 and August 2020 were studied. The patients were allocated randomized into two groups. Patients in experimental group were treated with basiliximab as immune induction therapy, but basiliximab was not used in patients of control group. Tacrolimus combined methylprednisolone were used after liver transplantation. The clinical characteristics, graft and recipient survival rate, rejection, infectious complications, and kidney functions after liver transplantation were observed. Donor specific antibody (DSA) was tested in 3 months after liver transplantation. The growth and development were assessed too after liver transplant.ResultsFourty-four patients were enrolled in the study, including 19 patients in the experimental group and 25 patients in the control group. The median follow-up time was 16.6 months (3.8–25.4 months), and there were no statistically differences between the two groups in terms of age, sex, weight, pediatric end-stage liver disease (PELD) score, and other basic conditions. There were no significant differences between the two groups in tacrolimus dose, tacrolimus trough concentration, kidney functions, height and weight growth after liver transplantation. There were no statistical differences in lung infection, blood stream infection within 3 months after liver transplantation, cytomegalovirus, EBV infection, graft/patient survival rate after liver transplantation (P>0.05). However, the acute rejection rate was lower and the DSA positive rate in 3 months after liver transplantation was lower in the experimental group (P<0.05).ConclusionsBasiliximab can be safely used in ABO incompatible pediatric liver transplant recipients. Acute rejection rate and DSA positive rate after transplantation can be decreased with the useof basiliximab.
Objective To report the experiences of cardiac valve operation in children. Methods Cardiac valve operations were performed in 87 children who were 58 male and 19 female between age of 4 to 14 years (mean 10.2 years). Of the 87 patients, 36 underwent mitral valve replacement, 13 aortic valve replacement, 6 mitral and aortic valve replacement, 13 aortic valvuloplasty, and 19 mitral valvuloplasty. Associated cardiac lesions were simultaneously managed. Results Postoperative complications included low car...
Febrile seizure is one of the most common emergencies in children, accounting for about 30% of all types of children, and the most common among children aged 6 months to 5 years. At the same time, children in this age group are at the peak of growth and development, and the content of various trace elements in the body is prone to abnormalities. At present, there are few related studies on febrile seizure and trace elements in children. This paper summarizes the related studies on febrile seizure and trace elements in order to provide theoretical guidance for the prevention and treatment of febrile seizure
Acetabuloplasty was used to treat 62 cases (76 hips) of congenital dislocation of hip in older children, with a period of follow-up for 1 to 7 years. The good results from operation rated 81.7 percent. It was considered that this type of operation could fulfil the physiological requirements, as the femoral head replaced into the acetabulum would accomplish the following benefits from establishing a stable joint, reducing the lumbar lordosis and minimizing development of hip and low back pain. The technique ...
In November 2022, the International Liaison Committee on Resuscitation updated the International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations for the sixth time. The 2022 review includes 21 topics addressed with systematic reviews by the Recovery Task Force of International Liaison Committee on Resuscitation. Among them, there are nine topics related to life support for newborns and children, including public-access defibrillation devices for children, pediatric early warning systems, maintaining normal temperature immediately after birth, suctioning of amniotic fluid at birth, tactile stimulation for resuscitation immediately after birth, use of continuous positive airway pressure for respiratory distress at term birth, respiratory monitoring in the delivery room, heart rate monitoring in the delivery room, and supraglottic airway use in neonates. The Task Force made treatment recommendations for each of the above topics after weighing evidence and discussion. In some cases, good practice statements have been provided for topics thought to be of particular interest to the resuscitation community when the evidence is insufficient to support a recommendation. Good practice statements are not recommendations but represent expert opinion. In order to facilitate the readers to understand the treatment recommendation well, in the recommendation basis part, the basic principle is briefly described. In addition, the existing problems and future research directions of each topic after the systematic reviews are also clearly stated.
Since the 13th Five-Year Plan proposed to practice capacity building in pediatrics and promote rehabilitation of persons with disabilities, children’s rehabilitation in China has achieved large-scale and all-round development in medical care, education, and scientific research. These include the effective implementation of the children’s health program, the establishment of a basic public service system for children with disabilities, the building of a talent pool, and the continuous improvement of evidence-based research. However, there are still some problems such as insufficient total service resources, uneven distribution, shortage of high-quality resources and specialized talents, and lack of high-quality evidence-based evidence for featured technologies. Entering a new stage of development, we need to comprehensively improve the capacity of rehabilitation services for children, further standardize quality control, promote the spread and application of appropriate technologies, accelerate personnel training, promote the research, development, and implementation of new technologies, and improve the health of children throughout their life cycle.
