RESUMO

The aim of this study was to analyze the role of thiol/disulfide homeostasis (TDH) parameters as an indicator of oxidative stress in acute appendicitis (AA). PubMed, EMBASE, Web of Science, and Scopus databases were systematically searched. Studies reporting on TDH in AA (both complicated and uncomplicated cases) were included. The comparator group were healthy controls. The TDH domain was compared between the groups using anti-oxidant parameters, namely native thiol and total thiol levels, and native thiol/total thiol ratio; and oxidant parameters, namely disulfide level, disulfide/native thiol ratio, and disulfide/total thiol ratio. The statistical analysis was performed using a random-effects model. The methodological quality of the studies was assessed utilizing the Newcastle-Ottawa scale. Eleven studies with a total of 926 subjects, comprising 457 patients with uncomplicated appendicitis, 147 with complicated appendicitis, and 322 healthy controls were included. Our study demonstrated significantly increased oxidative stress in AA as compared to healthy controls in all TDH parameters and significantly lower total thiol levels in complicated AA as compared to uncomplicated AA. Due to a poor methodological quality in five out of eleven studies, future prospective studies with adequate power are essential to validate these observations and refine the diagnostic approaches to AA.

RESUMO

The aim of this study was to compare the operative parameters and complication rates between the umbilical (UMB) and right upper quadrant (RUQ) skin incisions for Ramstedt's pyloromyotomy for the treatment of infantile hypertrophic pyloric stenosis (IHPS). PubMed, EMBASE, Web of Science and Scopus databases were systematically searched. The studies where any one of the main outcomes of interest, i.e., operative time, wound infection rate, mucosal perforation rate were reported were eligible for inclusion. The statistical analysis was performed using a random-effects model. The methodological quality of the studies was assessed utilizing the Newcastle-Ottawa Scale. Fifteen studies comprising 2964 infants were included. As compared to the UMB group, the RUQ group showed a significantly lower mean operative time (p = 0.0004), wound infection rate (p < 0.0001) and mucosal perforation rate (p = 0.02). Although UMB incision produces an almost undetectable scar, this approach results in significantly more complications. Therefore, the risks and benefits must be weighed and discussed with the caregivers in deciding the surgical approach in patients with IHPS. However, due to a poor methodological quality of nine out of fifteen studies, further studies need to be conducted for an optimal comparison between the two groups.

RESUMO

OBJECTIVE: We evaluated ductal closure rates in preterm neonates with hemodynamically significant patent ductus arteriosus (hsPDA) who received paracetamol (PCM) as first-line therapy. METHODS: In this retrospective chart review, we included inborn preterm (< 37 weeks) neonates (January 2017-December 2021) with hsPDA (ductal diameter > 1.5 mm and left atrium-to-aortic root ratio (La/Ao > 1.4) who were treated with oral or intravenous PCM. Primary outcome was hsPDA closure (defined as small or no PDA) following 3-day treatment. Secondary outcomes were need for retreatment and surgical ligation, pulmonary hypertension (PH), and in-hospital morbidities. RESULTS: Out of 2784 preterm birth, 117 neonates were diagnosed with hsPDA. Out of 96 neonates who received PCM in the first course, 20 died before the completing the first course. The median (IQR) gestation and birth weight of neonates who received PCM were 28 (26, 29) weeks and 841 (714, 1039) g, respectively. Out of 76 neonates who completed treatment with first course of PCM (57 intravenous, 19 oral), 43 (56.6%) achieved successful closure and five (6.6%) developed PH. Out of 14 neonates who received a second course of PCM, 10 achieved closure of hsPDA while one neonate expired. CONCLUSION: Paracetamol is associated with successful closure of hsPDA in 56.6% of preterm neonates after one course and 70% of premies after two courses.

RESUMO

Background: Ventilating a pediatric patient during thoracoscopy is challenging. Few studies have highlighted the impact of capnothorax in children by measuring regional cerebral oxygen saturation (rcSO2) with near infrared spectroscopy. In this systematic review, we aimed to summarize the data from relevant studies and assess whether thoracoscopy in children is associated with intraoperative pathological cerebral desaturation. Methods: The authors systematically searched four databases for relevant studies on the measurement of rcSO2 during pediatric thoracoscopic procedures. The primary outcome was the proportion of patients with pathological desaturation, that is, >20% decline in the intraoperative rcSO2. Risk of bias among the included studies was estimated using the Newcastle-Ottawa scale. Results: The systematic search resulted in 776 articles, of which 7 studies were included in the analysis. In total, 88 patients (99 procedures) with an age ranging from 0 days to 8.1 years were included. Of these, 43 (49%) patients were neonates. The included cohort had esophageal atresia and tracheoesophageal fistula (n = 26), long-gap esophageal atresia (n = 5), congenital diaphragmatic hernia (n = 14), and congenital pulmonary airway malformations and other conditions needing lung resection (n = 43). Of the total 99 procedures, pathological desaturation was noticed in 13 (13.1%, 95% confidence interval 7.2-21.4) of them. Upon quality assessment, most of the studies were weaker in the selection and comparability domains. Conclusion: In this review, pathological cerebral desaturation was noticed in 13.1% of the pediatric thoracoscopic procedures. However, due to limited methodological quality of the included studies, further randomized multicentric studies comparing rcSO2 in open versus thoracoscopic surgeries are needed to derive definitive conclusions.

RESUMO

Neonates with absent-or-reversed umbilical artery end-diastolic flow (AREDF) are at an increased risk of feeding problems. In this retrospective study, authors evaluated the incidence of feed intolerance in 213 preterm neonates (January 2017-May 2022) with AREDF. The median (IQR) gestation and birth weight were 32 (30, 33) wk and 1120 (840, 1425) g, respectively. Of 213 neonates, 103 (48.4%; 95% CI 41.5%, 55.3%) neonates developed feed intolerance. Twelve of 213 neonates developed any stage necrotizing enterocolitis (NEC) (5.6%; 95% CI 2.9%, 9.6%) at a median age of 10 d. On multivariate regression, gestation was the only independent predictor of feed intolerance (OR 1.48; 95% CI 1.28, 1.70; for every 1 wk decrease below 36 wk). Almost 50% of preterm neonates with AREDF develop feed intolerance. Alternative feeding strategies warrant exploration to optimise nutrition in these neonates.

RESUMO

BACKGROUND: Acute appendicitis is a frequently encountered surgical emergency. Despite several scoring systems, the possibility of delayed diagnosis persists. In addition, a delayed diagnosis leads to an increased risk of complicated appendicitis. Hence, there is a need to identify biological markers to help clinicians rapidly and accurately diagnose and prognosticate acute appendicitis with a high sensitivity and specificity. Although several markers have been evaluated, the pressing concern is still the low specificity of these markers. One such marker is serum ischemia-modified albumin (IMA), which can be a novel biomarker for accurately diagnosing and prognosticating acute appendicitis. METHODS: The authors conducted a systematic search of the PubMed, EMBASE, Web of Science, and Scopus databases through February 2023 as per the PRISMA guidelines. The difference in the levels of IMA between patients with acute appendicitis vs. healthy controls, and the difference in the levels of IMA between patients with complicated vs. non-complicated acute appendicitis were taken as the outcome measures. Statistical analysis was performed using a random effects model and mean difference (MD) was calculated. The methodological quality of the studies was assessed by utilizing the Newcastle-Ottawa scale. RESULTS: A total of six prospective comparative studies were included in the meta-analysis. The analysis revealed that the mean level of serum IMA was significantly raised in the acute appendicitis group (MD 0.21, 95% CI 0.05 to 0.37, p = 0.01). Similarly, the mean serum IMA levels were also raised in the complicated appendicitis group compared to the non-complicated appendicitis group (MD 0.05, 95% CI 0.01 to 0.10, p = 0.02). Three of the studies included were, however, of poor methodological quality. CONCLUSIONS: Serum IMA is a viable potential marker for diagnosing and prognosticating acute appendicitis. However, due to the limited methodological quality of available studies, further prospectively designed and adequately powered studies are needed.

RESUMO

Background: Magnetic compression anastomosis (MCA) is an alternative technique for patients with long-gap esophageal atresia (EA). It allows for preservation of the native esophagus. We aimed to systematically summarize the current literature on MCA in EA. Methods: Studies where neonates with EA were treated with MCA devices were included, while studies on esophageal stenosis were excluded. All clinical studies, including comparative studies, case series, and case reports, were eligible for inclusion. Methodological quality assessment was performed using a validated tool. Results: Twelve studies with a total of 42 patients were included in this review. There was a wide variation among these studies with regard to the time of initiation of MCA (1 day to 7 months), procedure time (13-320 minutes), and magnet characteristics (strength, size, and shape of the magnets used). The time to achieve anastomosis ranged from 1 to 12 days. Stricture at the anastomotic site was reported in almost all the patients, which required multiple endoscopic dilatations (median no. of dilatations/patient = 9.8). Stent placement for refractory stricture was required in 9 (21%) patients, and surgery for stricture was required in 6 (14%) patients. Long-term outcomes included esophageal dysmotility (n = 3) and recurrent pulmonary infections (n = 3) were reported in only four studies. Conclusion: As per the findings of this review, neonates with long-gap EA undergoing MCA would invariably require multiple sittings of endoscopic dilatations (median no. of dilatations/patient = 9.8). Also, there is a wide variation among the included studies in terms of the procedure of MCA. Future studies with a standardized procedure for achieving MCA are needed to determine additional outcomes in this fragile patient population.

RESUMO

Isolated renal mucormycosis is rare in children. A case of 3-month-old infant presenting with right-sided flank lump and fever is being reported. Investigations revealed a nonfunctioning right kidney with intrarenal abscesses and a low percent-frequency of T-cells. He made an uneventful recovery following surgery and systemic antifungal therapy. Compared to the other forms of deep mucormycosis, a review of literature suggests favorable prognosis in children with isolated renal involvement.

RESUMO

Background and objective Fragility Index (FI) of meta-analyses determines their stability in terms of the level of confidence and strength behind the results depicted by them. The present study was conducted to estimate the FI of recently published meta-analyses in the Journal of Pediatric Urology (JPUrol). Method Twenty recently published articles on meta-analyses were screened to identify the eligible ones. The baseline data of each meta-analysis including the details of the author, number of included studies, total sample size, the total number of events, the status of the overall outcome (significant or non-significant), type of effect measure, type of method used for pooling the estimates, and type of effects model were recorded. FI was calculated by doing each single status modification. The 95% CI of the treatment effect was re-calculated until the statistical significance of the meta-analysis was reversed. Results A total of seven articles incorporating 22 meta-analyses were included. Seven (32%) of them had a statistically significant outcome prior to FI estimation. The risk ratio (17/22; 77%) was the most commonly used effect measure. The random-effects model (15/22; 68%) and the Mantel-Haenszel method (20/22; 91%) of pooling the estimates were utilized in the majority of meta-analyses. The median (Q1-Q3; range) FI of statistically significant, non-significant, and total meta-analyses were 5 (3-19.5; 2-39), 5 (3.5-6; 1-17), and 5 (3-13; 1-39) respectively. FI of ≤5 was noticed in four out of seven (57%), 9/15 (60%), and 13/22 (59%) of these meta-analyses respectively. Conclusion Based on our findings, the majority of the recently published meta-analyses in the field of pediatric urology are fragile and depend upon the event status of ≤5 participants.

RESUMO

Esophageal atresia-tracheoesophageal fistula (EA-TEF) is one of the common congenital anomalies occurring in newborns. Over the last eight decades, various technical modifications have been proposed in the surgical repair of EA-TEF. Preservation of azygos vein is one such modification that has gained considerable attention. However, a consensus statement regarding the superiority of its preservation over its division is lacking. We aim to compare the outcomes of surgery between the two groups of newborns, i.e., those undergoing repair with and without azygos vein preservation, in terms of its complications. The authors systematically searched the databases PubMed, EMBASE, Web of Science, and Scopus through December 2020. The incidence of anastomotic complications and chest infection was compared among the two groups of newborns, i.e., those undergoing surgical repair with (group A) and without azygos vein preservation (group B). Statistical analysis was performed using a fixed-effects model, and pooled risk ratio (RR) and heterogeneity (I2) were calculated. The methodological quality of the studies was assessed using the Downs and Black scale. Six comparative studies, consisting of a total of 671 newborns, were included in the meta-analysis. As compared to group B, newborns belonging to group A showed a significantly lower incidence of pneumonitis in the postoperative period (RR 0.31; 95% CI 0.17-0.57, p = 0.0001). However, no significant difference in the incidence of anastomotic complications including anastomotic leak (RR 0.73; 95% CI 0.48-1.12, p = 0.15) and stricture (RR 0.63; 95% CI 0.36-1.09, p = 0.10) was observed between the two groups. The average Downs and Black scale scores ranged from 20 to 24. The risk of bias was low (n = 1) and moderate (n = 5) in the included studies. Kappa statistics showed a value of 0.902 (p < 0.001), highlighting an almost perfect agreement among the two observers. The present meta-analysis revealed the superiority of surgical repair of EA-TEF performed with preservation of azygos vein in terms of the incidence of postoperative chest infection. However, no significant difference in the occurrence of anastomotic leak and stricture was observed between the two groups. The level of evidence of the published comparative studies is limited. Therefore, well designed, randomized controlled trial utilizing a standardized operative approach on a larger sample-size needs to be conducted for optimal comparison between the two approaches.

RESUMO

BACKGROUND AND OBJECTIVES: In children with nephrotic syndrome, steroids are the cornerstone of therapy for relapse. The adequate duration and dosage of steroids, however, have not been an active area of research, especially in children with infrequently relapsing nephrotic syndrome. This study investigated the efficacy of an abbreviated regimen for treatment of a relapse in this population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In a single-center, open-label, randomized controlled trial, we evaluated the efficacy of prednisolone as a "short regimen" (40 mg/m2 on alternate days for 2 weeks) compared with "standard regimen" (40 mg/m2 on alternate days for 4 weeks) for children aged 1-16 years who achieved remission of a relapse. The primary outcome was the proportion of children developing frequent relapses or steroid dependence at 12 months. RESULTS: A total of 117 patients were enrolled and randomized to short (55) or standard (62) regimen. Fourteen (24%) patients in standard regimen and 12 (23%) in short regimen developed frequent relapses or steroid dependence over a period of 1 year (risk difference, -1%; 95% confidence interval, -15 to 16; P=0.90). A large 95% confidence interval crossed the proposed noninferiority margin. In a time to event analysis, there was no significant difference in the proportion of children developing frequent relapses or steroid dependence and time to outcome between the two groups (hazard ratio, 1.01; 95% confidence interval, 0.83 to 1.23; P=0.98). Time to relapse, relapse rate, and steroid-related adverse events were similar in both groups. Cumulative steroid exposure was significantly lower in the short regimen (risk difference, -541 mg/m2; 95% confidence interval, -917 to -164 mg/m2; P<0.001). CONCLUSIONS: In children with infrequently relapsing nephrotic syndrome, a short steroid treatment for relapse resulted in a similar proportion of patients developing frequent relapses or steroid dependence; however, noninferiority of a short regimen was not established.
