  • Leaflet extension in reoperation after tricuspid valve repair in children

    Objective To summarize our experience on leaflet extension in reoperation after tricuspid valve repair in children at age≤15 years and to explore the application indicators and skills of this technique. Methods We retrospectively analyzed the clinical data of 23 children who underwent reoperation after tricuspid valve repair in Xinhua Hospital between January 2006 and October 2015. There were 15 males and 8 females with a mean age of 8.7 years, ranging from 5 to 15 years. The leaflet was extended by artificial pericardium patch. After surgery, warfarin anticoagulation therapy was done, and international normalized ratio was maintained 2.0 to 3.0. Results The average cardiopulmonary bypass time was 87-132 (98.5±35.7) minutes, and average aortic cross-clamping time was 56-97 (68.40±23.78) minutes. One patient died in hospital. There were 3 patients with complications including respiratory failure in 1 patient, acute renal failure in 1 patient, and right heart insufficiency in 1 patient. All the children cured and were followed up for 5 months to 10 years, with a mean follow-up of 3.5 years. One patient died during the follow-up. Six patients suffered mild to moderate tricuspid regurgitation and tricuspid valve function of the rest patients was good. No other redo-valve surgery or complications correlated to anticoagulation occurred. Conclusion Leaflet extension in reoperation after tricuspid valve repair in children is useful with optimistic middle to long term efficacy and needs intensive care therapy during the perioperative period.

  • Pediatric gastrointestinal foreign bodies: characteristics and risk factors for complications

    Objective To investigate the characteristics, complications, and influencing factors of pediatric foreign body ingestion, providing clinical references for prevention and management. Methods A retrospective analysis was conducted on pediatric cases of foreign body ingestion treated at West China Hospital of Sichuan University between June 2007 and September 2019. Patients were stratified by age into ≤5 years, 6-10 years, and >10 years groups. Foreign body types, impaction sites, and complication rates were compared across age groups. Univariate analysis and multivariate logistic regression were performed to identify risk factors for complications. Results A total of 610 pediatric cases of foreign body ingestion were enrolled. Foreign body ingestion predominantly occurred in children ≤5 years (n=472, 77.38%), followed by 6-10 years (n=100, 16.39%) and >10 years (n=38, 6.23%). Foreign body types varied significantly by age (P<0.05): coins predominated in ≤5-year-olds (57.20%), while food-related objects were most common in >10-year-olds (52.63%). The most frequent impaction site was the upper esophagus, accounting for 48.31%, 44.00%, and 60.53% in the three age groups, respectively. Univariate analysis identified age, foreign body type, and location as significant predictors of complications (P<0.05). Multivariate logistic regression demonstrated that oropharynx and esophageal impaction (reference: stomach) [odds ratio (OR)=4.699, 95% confidence interval (CI) (2.456, 8.996), P<0.001] and high-risk foreign body types [OR=3.538, 95%CI (2.045, 6.122), P<0.001] were independent risk factors for complications, whereas increasing age had a protective effect [OR=0.418, 95%CI (0.252, 0.694), P=0.001]. Conclusions Younger children are at higher risk of foreign body ingestion, while increasing age is protective against complications. High-risk foreign body types and oropharynx and esophageal impaction significantly increase complication risks. Strengthening parental education, preventive measures against high-risk objects, and enhancing clinicians’ vigilance for complex cases are essential to reduce complications.

    Objective To investigate the effectiveness of Salter osteotomy combined with subtrochanteric shortening and derotational osteotomy in treating Tönnis type Ⅲ and Ⅳ developmental dysplasia of the hip (DDH) in children and explore the urgical timing. Methods A retrospective collection was performed for 74 children with Tönnis type Ⅲ and Ⅳ DDH who were admitted between January 2018 and January 2020 and met the selection criteria, all of whom were treated with Salter osteotomy combined with subtrochanteric shortening and derotational osteotomy. Among them, there were 38 cases in the toddler group (age, 18-36 months) and 36 cases in the preschool group (age, 36-72 months). There was a significant difference in age between the two groups (P<0.05), and there was no significant difference in gender, side, Tönnis typing, and preoperative acetabular index (AI) (P>0.05). During follow-up, hip function was assessed according to the Mckay grade criteria; X-ray films were taken to observe the healing of osteotomy, measure the AI, evaluate the hip imaging morphology according to Severin classification, and assess the occurrence of osteonecrosis of the femoral head (ONFH) according to Kalamchi-MacEwen (K&M) classification criteria. Results All operations of both groups were successfully completed, and the incisions healed by first intention. All children were followed up 14-53 months, with an average of 27.9 months. There was no significant difference in the follow-up time between the two groups (P>0.05). At last follow-up, the excellent and good rates according to the Mckay grading were 94.73% (36/38) in the toddler group and 83.33% (30/36) in the preschool group, and the difference between the two groups was significant (P<0.05). The imaging reexamination showed that all osteotomies healed with no significant difference in the healing time between the two groups (P>0.05). There was no significant difference in AI between the two groups at each time point after operation (P>0.05), and the AI in the two groups showed a significant decreasing trend with time extension (P<0.05). The result of Severin classification in the toddler group was better than that in the preschool group at last follow-up (P<0.05). There was no significant difference in the incidence of ONFH between the two groups (P>0.05). In the toddler group, 2 cases were K&M type Ⅰ; in the preschool group, 3 were type Ⅰ, and 1 type Ⅱ. There was no dislocation after operation.ConclusionSalter osteotomy combined with subtrochanteric shortening and derotational osteotomy is an effective way to treat Tönnis type Ⅲ and Ⅳ DDH in children, and surgical interventions for children aged 18-36 months can achieve better results.

    Objective To investigate the effects of children’s crawling-promotion-training-robot on gross motor function and cognitive function in children with global developmental delay (GDD). Methods A total of 40 children with GDD admitted to the Department of Rehabilitation Medicine, Children’s Hospital of Nanjing Medical University were selected as the research subjects. By envelope method, the children were randomly and equally divided into experimental group and control group, with 20 cases in each group. The experimental group received children’s crawling-promotion-training-robot combined with conventional rehabilitation therapy, while the control group received manual crawling training combined with conventional rehabilitation therapy. Before and after treatment, the scores of Gross Motor Function Measure Scale-88 (GMFM-88) and Gesell Developmental Scale (GDS) were respectively used to evaluate gross motor function and cognitive function. Results There was no significant difference in gender (χ2=0.100, P=0.752) and age (t=0.053, P=0.962) between the two groups. Before treatment, there was no significant difference in GMFM-88 and GDS scores between the two groups (P>0.05). After treatment, there were statistically significant differences in GMFM-88 and GDS scores between the two groups (P<0.05). The comparison within the group showed that there were statistically significant differences in GMFM-88 and GDS scores between the two groups before and after treatment. Conclusion Children’s crawling-promotion-training-robot is more effective than manual crawling training in improving gross motor function and cognitive function in children with GDD.

  • Prospect of application of novel neuromodulation technology in children with drug-refractory epilepsy

    In the treatment of drug-refractory epilepsy in children, surgical treatment has a good clinical effect. However, for children whose surgical site is difficult to determine and who cannot undergo resectional surgery, neuromodulation techniques are one of the treatments that can be considered. At present, new neuromodulation technologies in children mainly include transcutaneous vagus nerve stimulation (transcutaneous auricular vagus nerve stimulation, ta-VNS), deep brain stimulation (deep brain stimulation, DBS), reactive nerve stimulation (responsive neurostimulation, RNS), transcranial magnetic stimulation (transcranial magnetic stimulation, TMS), transcranial direct current stimulation (transcranial direct current stimulation, TDCS) and transcranial alternating current stimulation (transcranial alternating current stimulation, TACS). This article briefly discussed the clinical efficacy and safety of various currently available neuromodulation technologies, so as to provide a reference for the rational selection and application of neuromodulation technologies, and improve the clinical efficacy and quality of life of children with drug-refractory epilepsy.

  • Clinical study of Cross-Union surgery for treatment of pseudarthrosis of tibia with neurofibromatosis type 1 in children

    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.

    Objective To explore the intervention effect of music therapy on children with autism spectrum disorder. Methods The China National Knowledge Infrastructure, Wanfang, Chongqing VIP, PubMed, Embase, Cochrane Library were searched by computer to comprehensively collect randomized controlled trials on the intervention effect of music therapy on children with autism spectrum disorder. The search period was from the establishment of the database to December 31, 2022. RevMan 5.4 software was used for meta-analysis. Results Finally, 20 articles were included, including 913 cases in the music therapy group and 811 cases in the control group, with a total sample size of 1724 cases. The meta-analysis results showed that the overall treatment effect [standardized mean difference (SMD)=−0.95, 95% confidence interval (CI) (−1.12, −0.78)], the treatment effect of language [SMD=−0.71, 95%CI (−0.84, −0.57)], behavior [SMD=−0.65, 95%CI (−0.78, −0.52)], social interaction [SMD=−0.52, 95%CI (−0.63, −0.40)], cognition [SMD=1.37, 95%CI (1.00, 1.74)] and sensory perception [SMD=−0.89, 95%CI (−1.03, −0.74)] of the music therapy group were better than those of the control group (P<0.05). Conclusion The existing data show that music therapy applied to children with autism spectrum disorder can effectively improve their language, behavior, social interaction, cognition, and sensory perception, thereby having a positive impact on the overall treatment effect of children. However, due to the limitations of the number and quality of included studies, more high-quality studies are needed to verify.

    Objective To analyze the effectiveness comparison of external fixator combined with Kirschner wire fixation and Kirschner wire fixation in the treatment of cubitus varus deformity in children. Methods A retrospective case-control study was conducted to collect 36 children of postoperative supracondylar humerus fracture complicating cubitus varus deformity between January 2018 and July 2022. Among them, 17 cases were treated with distal humeral wedge osteotomy external fixation combined with Kirschner wire fixation (observation group), and 19 cases were treated with distal humeral wedge osteotomy and Kirschner wire fixation (control group). The baseline data including age, gender, deformity side, time from fracture to operation, carrying angle of the healthy side and preoperative carrying angle of the affected side, elbow flexion and extension range of motion, and lateral condylar prominence index (LCPI) showed no significant difference between the two groups (P>0.05). The operation time, hospitalization cost, healing time of osteotomy, postoperative complications, and the carrying angle, LCPI, and elbow flexion and extention range of motion were recorded and compared between the two groups. The elbow function was assessed by Oppenheim score at 3 months after operation and at last follow-up. Results The children in both groups were followed up 13-48 months, with an average of 26.7 months. There was 1 case of needle tract infection in the observation group and 2 cases in the control group, and no nerve injury occurred, the difference in the incidence of complication (5.88% vs 10.53%) between the two groups was not significant (χ2=0.502, P=0.593). There was no significant difference in the operation time and fracture healing time between the two groups (P>0.05); the hospitalization cost of the observation group was significantly higher than that of the control group (P<0.05). The Oppenheim score of the observation group was significantly better than that of the control group at 3 months after operation (P<0.05), but there was no significant difference in the Oppenheim score between the two groups at last follow-up (P>0.05). At last follow-up, the carrying angle of affected side significantly improved in both groups when compared with preoperative ones (P<0.05); the differences of the pre- and post-operative carrying angle of affected side and elbow flexion and extension range of motion showed no significant differences between the two groups (P>0.05), but the difference in pre- and post-operative LCPI of the observation group was significantly better than that of the control group (P<0.05). ConclusionExternal fixator combined with Kirschner wire fixation and Kirschner wire fixation both can achieve satisfactory correction of cubitus varus deformity in children, and the former can achieve better short-term functional recovery of elbow joint and reduce the incidence of humeral lateral condyle protrusion.

    Objective To explore the effectiveness of thumb blocking technique through closed reduction of ulnar Kirschner wire threading in the treatment of Gartland type Ⅲ supracondylar humerus fractures in children. MethodsThe clinical data of 58 children with Gartland type Ⅲ supracondylar humerus fractures treated with closed reduction of ulnar Kirschner wire threading by thumb blocking technique between January 2020 and May 2021 were retrospectively analyzed. There were 31 males and 27 females with an average age of 6.4 years ranging from 2 to 14 years. The causes of injury were falling in 47 cases and sports injury in 11 cases. The time from injury to operation ranged from 24.4 to 70.6 hours, with an average of 49.6 hours. The twitch of ring and little fingers was observed during operation, the injury of ulnar nerve was observed after operation, and the healing time of fracture was recorded. At last follow-up, the effectiveness was evaluated by Flynn elbow score, and the complications were observed. Results There was no twitch of the ring and little fingers when the Kirschner wire was inserted on the ulnar side during operation, and the ulnar nerve was not injured. All children were followed up 6-24 months, with an average of 12.9 months. One child had postoperative infection in the operation area, local skin redness and swelling, and purulent secretion exudation at the eye of the Kirschner wire, which was improved after intravenous infusion and regular dressing change in the outpatient department, and the Kirschner wire was removed after the initial healing of the fracture; 2 children had irritation at the end of the Kirchner wire, and recovered after oral antibiotics and dressing change in the outpatient department. There was no serious complication such as nonunion and malunion, and the fracture healing time ranged from 4 to 6 weeks, with an average of 4.2 weeks. At last follow-up, the effectiveness was evaluated by Flynn elbow score, which was excellent in 52 cases, good in 4 cases, and fair in 2 cases, and the excellent and good rate was 96.6%. ConclusionThe treatment of Gartland type Ⅲ supracondylar humerus fractures in children by closed reduction and ulnar Kirschner wire fixation assisted with thumb blocking technique is safe and stable, and will not cause iatrogenic ulnar nerve injury.
