Common Salt versus Silver Nitrate for the Treatment of Umbilical Granuloma in Infants: An Open-label, Single-center, Pilot Randomized Controlled Trial.

Aim: This study aims to compare the efficacy and safety of topical application of common salt (CS) in comparison to silver nitrate (SN) for treating infants with umbilical granuloma (UG). Materials and Methods: We conducted an open-label, prospective, single-center, pilot randomized controlled trial. Thirty-seven infants with a clinical UG diagnosis were enrolled between October 2022 and July 2023, excluding those previously treated for UG. Patients were randomly assigned (using the Randomizer® app) to receive either topical CS (applied thrice daily by caregivers at home for 5 days) or SN (applied by pediatric surgeon in clinic and kept under occlusive dressing for 48 h). Patients with partial/no healing received an additional session of the same treatment. Nonresponders transitioned from CS to SN, and vice versa, for two more applications. Healing rates were compared with a significance level of α =0.05. Results: Out of 34 patients (18 CS and 16 SN), 32 successfully completed the trial (17 CS and 15 SN). No significant differences were observed in baseline characteristics. Efficacy rates of CS (19/22; 86.36%) and SN (11/17; 64.71%) did not significantly differ (P = 0.056; 95% confidence interval [CI] -0.4832-0.0502). No major adverse events were reported. CS showed superior healing outcomes in infants below 3 months of age (19/22; 86.36%) compared to SN (11/17; 64.71%) (P = 0.056; 95% CI - 0.4832-0.0502). The timing of umbilical cord detachment did not significantly affect healing rates. Conclusion: Widespread availability, ease of access, suitability for safe home application, and cost-effectiveness make CS a primary treatment option for UG. Larger patient cohorts are needed for conclusive results.

Application of the Clamshell Thoracotomy in an Infant with a Large Mediastinal Tumor.

Historically it was recommended for emergency thoracotomy in thoracic trauma as the last resort when there was cardiopulmonary arrest. Nowadays, the only indications are lung transplantation and huge mediastinal masses. We report the use of a clamshell thoracotomy in a 7-month-old boy with a large anterior mediastinal mass extending into the bilateral thoracic cavities.

Impact of Cytomegalovirus Infection on Short-Term Clinical Outcomes and Operative Histopathology in Infants with Biliary Atresia: A Single-Center Prospective Cohort Study.

Background: There is limited information on the impact of cytomegalovirus (CMV) infection on clinical outcomes and operative histopathology in children with biliary atresia (BA). We hypothesized that CMV infection is associated with greater histopathological damage and unfavorable short-term clinical outcomes. Materials and Methods: A prospective single-center study was conducted with effect from January 2011-July 2012 including all infants with BA who underwent surgery. Diagnosis of CMV infection was confirmed by serum immunoglobulin M (IgM) positivity or the presence of CMV-deoxyribonucleic acid (DNA) in the liver tissue. Four short-term outcome variables were observed. The cohort was divided into subgroups on the basis of seropositivity (IgM + or IgM-); the presence of CMV-DNA in the liver (polymerase chain reaction [PCR]+ or PCR-); and composite CMV groups (Group 1 - IgM+, PCR+; Group 2 - IgM+, PCR-; Group 3 -- IgM-, PCR+; and Group 4 - IgM-, PCR-). Outcomes and histopathology were compared in these subgroups. Results: A total of 32 infants with BA were operated at a mean age of 3.5 (range: 1-6) months. Serum IgM+ and PCR+ were observed in 50% and 37.5% of the patients. Unfavorable outcomes showed a significant association with IgM+ and not PCR+. Similarly, outcomes were poor for CMV Groups 1 and 2 at 1-month follow-up. Infants with IgM+ and PCR+ showed a greater degree of histopathological damage in terms of bile duct proliferation and severe bile duct fibrosis, respectively. Conclusion: In the present study, there was a high incidence of serum IgM+ (50%) and PCR+ of biopsy specimens (37.5%) in infants with BA. This CMV-infected subgroup was associated with greater histopathological damage and unfavorable short-term outcomes after surgery.

Pediatric Zinner syndrome variants: Case series with newer insights into pathogenesis in early childhood.

INTRODUCTION: Zinner Syndrome (ZS) is a rare congenital disorder characterized by seminal vesicle cysts (SVC) and ipsilateral upper urinary tract abnormalities, mainly due to developmental anomalies of the mesonephric duct. This series highlights our institutional experience with pediatric ZS, with a review of the current literature offering insights into its etiopathogenesis in early childhood. MATERIAL AND METHODS: A retrospective case review of pediatric ZS diagnosed at our institution from 2019 to 2023, alongside a comprehensive literature review. RESULTS: Four pediatric ZS cases were identified, a neonate, an infant and two older (pre-pubertal) children, presenting with recurrent epididymo-orchitis and/or UTIs. The two older children had duplex systems, both undergoing curative upper moiety heminephrectomy; the infant underwent nephroureterectomy and the neonate is under observation, asymptomatic for past 18 months. DISCUSSION: When Zinner identified the link between unilateral renal agenesis and ipsilateral SVC in 1914, the condition's embryological basis was attributed to incorrect ureteric bud migration from the mesonephric duct, failing to stimulate the metanephros, leading to renal agenesis/dysplasia and this disruption was hypothesized to obstruct seminal vesicle drainage, causing cyst formation. Another theory suggests anomalous development of the distal mesonephric duct leading to ejaculatory duct atresia/stenosis which results in cystic enlargement of the seminal vesicles which, in turn, leads to aberrant ureteral budding, resulting in renal malformations. It is our belief that the SVCs, that are typically problematic in adolescence/adulthood due to secretion accumulation, sometimes manifest in childhood due to urinary reflux into the seminal vesicles, leading to epididymo-orchitis or UTIs. This contrasts with adult pathogenesis, where ejaculatory duct obstruction predominates. Hence, treatment leans towards a conservative approach for asymptomatic cases, with surgery reserved for symptomatic children. The scope of this case series is limited by the rare nature of ZS in prepubertal children (41 published cases in English literature), preventing a comprehensive understanding of its untreated natural history and restricting the formulation of generalized recommendations. CONCLUSION: The variability in presentation of ZS in children necessitates a tailored approach. Unlike adults, where ejaculatory duct obstruction is the common cause, pediatric ZS symptoms mainly stem from urethra-cystic reflux, leading to recurrent infections.

Treatment of Umbilical Granuloma in Infants With Topical Application of Common Salt: A Scoping Review.

BACKGROUND: Common salt is a safe, effective and cheap home-made remedy for umbilical granuloma. The aim of this scoping review is to identify and summarize the available evidence and examine the research conducted on salt treatment for umbilical granuloma. METHODS: A literature search was performed in the second week of September, 2022 using Google scholar, PubMed, MEDLINE and EMBASE databases using the keywords 'umbilical granuloma' and 'salt treatment' to identify all English articles pertaining to salt treatment for umbilical granuloma. Tables were made to summarize the methodological characteristics, results and the dosage regimens of salt used by different authors. The Cochrane Collaboration's tool was used for assessing risk of bias in RCTs. The indexing statuses of the journals publishing these studies were also noted. The overall efficacy with the use of common salt was calculated by adding the success rates mentioned in each study. RESULTS: Twenty-four articles (2 systematic reviews, 6 Randomized Controlled Trials, 11 prospective cohort studies, 1 case control study, 3 retrospective case series and 1 case report) were included. An overall 93.91% success rate (1033/1100) was seen with common salt application, without any reports of complications/recurrences. CONCLUSION: Topical application of common salt for umbilical granulomas is simple, effective and inexpensive. This scoping review provides a broader outlook at the existing level of evidence and may help in planning interventional comparative studies, so that recommendations can be formulated. It also highlights a lack of properly designed randomized controlled trials on this topic. LEVEL OF EVIDENCE: I.

Primary yolk sac tumor of the common bile duct.

Yolk sac tumor (YST) is a germ cell neoplasm usually arising from the gonads. Extragonadal YST has been reported in the mediastinum, retroperitoneum, liver, and pelvis. Primary YST of the common bile duct (CBD) has not been previously reported. We describe an 11-month-old girl with a YST arising from the CBD who presented with obstructive jaundice. Imaging studies revealed an intraluminal CBD mass with intrahepatic biliary dilatation and extraluminal infiltration of the head of the pancreas. A complete resection was carried out, and postoperative chemotherapy with cisplatin, etoposide and bleomycin was administered.

Pediatric clear cell sarcoma of the kidney with cavoatrial thrombus.

Clear cell sarcoma of the kidney (CCSK) is a rare renal tumor. Only 4 cases of CCSK with vascular thrombus have been reported, and 2 of these were pediatric cases. One of the children had an intraatrial thrombus as well. We describe a 3-year-old boy who was diagnosed as having a Wilms tumor but did not respond to preresection chemotherapy. He underwent complete resection of the tumor under cardiopulmonary bypass. Histologic examination indicated that the tumor was a CCSK. The patient was then managed with appropriate chemotherapy and radiation therapy and is well 16 months after diagnosis.
