The study hypothesizes that the concordance of IED sites with surgical sites indicates incomplete resection of epileptic focus, while non-concordance of IED sites with surgical sites indicates postoperative changes or cortical stimulation. The former has a higher risk of seizure recurrence. Methods We retrospectively analyzed the postoperative EEG pattern of 182 consecutive children who underwent resection surgery. To identify the risk factors for seizure recurrence, we compared the attributes of seizure recurred and seizure-free groups by univariate and multivariate analyses. AED tapering was standardized, involving a 25% reduction in the dose of a single type of AED every 2 weeks, independent of the presurgical AED load. Results We attempted AED withdrawal in 116 (63.7%) children. Twenty-eight (24.1%) children experienced seizure recurrence during or after AED withdrawal. A greater number of AEDs used at the time of surgery ( p =0.005), incomplete resection ( p =0.001), and presence of IED on postoperative EEG ( p =0.011) are predictors of seizure recurrence. The completeness of resection and seizure recurrence after AED withdrawal were related to the presence of IED on the EEG, but not to the concordance of IED with surgical sites. Conclusion For children with abnormal EEG, the decision to discontinue AED should be made more cautiously, regardless of the relative location of the discharge site and the surgical site. All data relevant to the study are included in the article or uploaded as supplementary information.","PeriodicalId":23823,"journal":{"name":"World Journal of Pediatric Surgery","volume":"98 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139766998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conflict has strained the region’s fragile healthcare system, resulting in a significant number of casualties, a substantial proportion of which are children. This exacerbates the demand for specialized pediatric surgical care, especially when the existing healthcare system and infrastructure has nearly collapsed and is under-resourced to handle the influx of pediatric patients.2 The urgency for specialized pediatric surgical care and support for children in Gaza cannot be overstated. Access to healthcare in Palestine has been an ongoing challenge.3 Before the recent hostilities, 1.1 million children in Gaza and the West Bank were already in need of humanitarian aid, constituting approximately half of the child population.4 The current war in Gaza, as per a recent UNICEF report, has exacerbated the situation, with hundreds of thousands of children in desperate need of humanitarian assistance and protection.5 Team members of Médecins Sans Frontières (MSF) who are currently provding medical care in Gaza, have expressed deep concern regarding the critical medical and humanitarian crisis facing children in the region. Nearly half of the consultations MSF staff provided in the Martyrs and Beni Suheila clinics, in which they have now been forced to suspend operations in, were for children under the age of five.6 The conflict has resulted in a significant number of casualties, with a substantial proportion being children who require specialized pediatric surgical care.

This study aims to compare the reported outcomes of Tubularized incised plate urethroplasty (TIP) and Grafted TIP (GTIP) repair in children undergoing primary hypospadias repair. Methods This meta-analysisadhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and we framed our research question using the population, intervention, control and outcomes format. We conducted comprehensive electronic searches across various databases, employing a Boolean search strategy with predefined search terms. Only randomized controlled trials (RCTs) were included for quantitative analysis. Results Totally, 10 RCTs met our inclusion criteria for quantitative analysis. The results indicated that urethrocutaneous fistula, glans dehiscence, and stricture rates were comparable between the two groups.

The push technique is being increasingly used, but its complications are insufficiently characterized. We aimed to assess all complications related to PEG procedures and compare the safety of the pull and push techniques. Methods Retrospective review of consecutive pediatric patients who underwent PEG between 2002 and 2020. Results In total, 216 children underwent 217 PEG procedures. The push technique was used in 138 (64%) cases, and the pull technique in 79 (36%) cases. The median follow-up time was 6.1 (0.1–18.3) years. The complication rate was high (57%) and patients experienced complications years after the procedure. Overall, 51% and 67% of patients experienced complications in the push and pull groups, respectively. The rates of minor and major complications were higher in the pull group than in the push group (63% vs 48%, p =0.028; and 11% vs 6%, p =0.140, respectively). Reoperation was also more common in the pull group (17% vs 7%, p =0.020). Conclusions The overall complication rate of PEG procedures is high. Fortunately, most complications are mild and do not require reoperations. The increasing push technique appears to be safer than the traditional pull technique.

Our study examines pediatric fire pit burns characteristics to raise awareness and promote safety precautions. Methods We conducted a retrospective review of pediatric patients (≤21 years) with firepit burns at a tertiary care hospital from 2016 to 2021. Results Eighty-four patients were identified, of whom 70.2% were male, with a median age of 62 months. The median percent total body surface area burned was 2% (interquartile range (IQR)=1–4). Thirty-five (41.7%) patients were admitted and 7 (8.3%) underwent grafting. Neck and trunk burns had the highest grafting rates (66% and 33%, respectively). The hands (41.7%) and the lower extremities (27.4%) were the most frequently burned body areas. The leading causes of burns were ashes/hot coals (34.5%), flames (31.0%), and direct contact (25.0%), often resulting from falling into the fire (59.5%) or running or playing in activities near it (26.2%). Thirty-five (41.7%) were admitted for inpatient management, while 49 (58.3%) were treated as outpatient. Eleven (13.2%) underwent at least one reconstructive surgery, 7 (8.4%) had at least one rehabilitation visit, and 65 (77.4%) had follow-up clinic visits. The median length of stay was 2 days (IQR=1.0–3.5). The peak months for burns were from August through October ( n =40, 46.0%), with an increase observed from 10 cases in 2016 to 20 cases in 2020.

The goals of definite reconstruction are to separate the rectum from the urinary tract without injuring the urethra and mobilizing the rectum to the perineum within the muscle complex. Separating the rectum and the urinary tract is the most critical part of this operation and is associated with a significant risk of urinary tract injury.2–5 The original procedure described by Peña and Devries involves multiple stay sutures on the rectal mucosa just above the fistula, lifting the mucosa and continuing a submucosal dissection up to the prostate, where the entire thickness of the intestine can be separated from the urinary tract.6 These stay sutures have the inherent risk of incorporating the urethra within and thereby injuring the urethra. Moreover, this submucosal dissection is delicate and requires master’s expertise to avoid urethral injury, which frequently occurs in boys with relatively benign lower malformation. However, a relatively significant space separates the rectum and the urinary tract proximal to the common sharing wall (figure 1). By first mobilizing the rectum proximally in an antegrade fashion and lifting it from the urinary tract with a loop, the posterior wall of the urethra, prostate, and bladder is easily visible. This also establishes a clear boundary between the rectum and urinary tract, making it possible to resect the fistula precisely without needing a traction suture .

Developing surgical infrastructure requires information on surgical need; however, this information is often limited in LMICs. North Korea (Democratic People’s Republic of Korea, DPRK) has a low amount of publicly available data. Here, we analyzed available modeled data to understand the causes of pediatric deaths due to conditions treatable with surgery in DPRK. Methods We used World Bank data and models from the Institute for Health Metrics and Evaluation to identify causes of pediatric deaths affecting pediatric patients (age <20 years). We compared mortality of disease between DPRK and countries with similar economic status. Results Between 1990 and 2019, the number of overall pediatric deaths has decreased. In 2019, 32.2% of all pediatric deaths in DPRK were caused by surgical conditions. The leading categories of surgical conditions were injuries (53.9%), congenital conditions (34.2%), tumors (8.8%), and abdominal conditions (3.2%). DPRK has a lower relative rate of pediatric deaths compared with other LMICs with similar gross domestic product per capita. However, it has a higher relative rate of pediatric deaths due to conditions requiring treatment with surgery. Transport injuries contribute significantly to the high rate of pediatric deaths in DPRK. Conclusions Although DPRK may be allocating overall resources toward pediatric healthcare more efficiently than economic peers, DPRK may benefit from improvement in pediatric surgical capacity. Improved availability of data and close international collaboration could be potential solutions to bridge this gap.

Methods Subjects with isolated left-sided CDH treated between 2007 and 2020 at a single pediatric surgical center were recruited and classified according to survival. Data obtained retrospectively for subject demographics, clinical course, LPA/RPA diameters, and PAR were compared between survivors and non-survivors. The value of PAR for optimizing the prognostic value of PA diameter data in CDH were analyzed with receiver operating characteristic (ROC) curve analysis. Results Of 65 subjects, there were 54 survivors (82.3%) and 11 non-survivors (17.7%); 7 of 11 non-survivors died before surgical repair could be performed. Mean PAR for survivors (0.851±0.152) was significantly higher than for non-survivors (0.672±0.108) ( p =0.0003). Mean PAR for non-survivors was not affected by surgical repair. Characteristics of survivors were: LPA ≥2 mm (n=52 of 54; mean PAR=0.866±0.146) and RPA ≥3 mm (n=46 of 54; mean PAR=0.857±0.152). Non-survivors with similar LPA and RPA diameters to survivors had significantly lower mean PAR. ROC curve cut-off for PAR was 0.762. Subjects with high PAR (≥0.762) required high-frequency oscillatory ventilation/NO less than subjects with low PAR (<0.762) ( p =0.0244 and p =0.0485, respectively) and subjects with high PAR stabilized significantly earlier than subjects with low PAR (1.71±0.68 days vs 3.20±0.87 days) ( p <0.0001).
