Clinical-pathological correlation of endoscopic findings in eosinophilic esophagitis in the pediatric population.

Eosinophilic esophagitis (EoE) is an immunologic disorder of the esophagus with an increasing incidence in our region of 8.1 cases per 100,000 inhabitants per year. It is characterized by dysphagia, and its diagnosis requires esophagoscopy with biopsies for histopathological analysis, which macroscopically reveals certain characteristic endoscopic findings, though their diagnostic utility remains uncertain. The correlation between these endoscopic findings and the histopathological diagnosis of EoE continues to be a subject of controversy in the pediatric population. This study evaluates the clinical-pathological association of different endoscopic abnormalities in EoE. We conducted an analytical study of patients under 15 years old who underwent esophagoscopy due to highly suspicious symptoms of EoE at a pediatric hospital between 2015 and 2022.

Correlation of endoscopic findings with histological alterations in pediatric ulcerative colitis.

Ulcerative colitis (UC) is a chronic and relapsing inflammatory bowel disease (IBD) characterized by abdominal pain and bloody diarrhea. Its diagnosis requires endoscopy and biopsies for histopathological analysis, revealing characteristic endoscopic findings. Currently, the correlation between these endoscopic abnormalities and the histopathological diagnosis of UC remains a controversial topic in pediatrics. This study evaluates the clinicopathological association of various endoscopic alterations in UC. We conducted an analytical study of patients under 15 years old who underwent upper and lower gastrointestinal endoscopy for suspected IBD at a pediatric hospital between 2015 and 2022.

Utility of the derived neutrophil-to-lymphocyte ratio as a predictor of complicated appendicitis in pediatrics.

Between 16-40% of patients present with complicated appendicitis at the time of diagnosis, making early suspicion of appendicular perforation key for initiating timely treatment and reducing morbidity and mortality. This study evaluates the accuracy of the derived neutrophil-to-lymphocyte ratio (dNLR) as a predictor of complicated appendicitis. A diagnostic study was conducted, including patients aged 0-15 years who underwent appendectomy at a pediatric hospital between 2021-2022 (Reg. 2023/390894).

Esophageal atresia type III? Intraoperative surprise and different approaches.

A newborn was referred due to clinical and radiological suspicion of esophageal atresia (EA) type III. Surgery revealed an esophagus without evident interruptions; however, intraoperative advancement of the nasogastric tube was unsuccessful, and the distal esophagus inflated with each ventilation, indicating the presence of a distal fistula. An intraoperative esophago-tracheobronchoscopy showed a proximal esophageal pouch with a tiny tracheoesophageal fistula and a large distal tracheoesophageal fistula. The esophageal ends were blind but overlapping, with no external discontinuity observed. With the diagnosis of Krediet type IIIc2 esophageal atresia, we performed a meticulous esophago-tracheal dissection, distal fistula closure, and end-to-end anastomosis. Due to hemodynamic instability, the proximal fistula was closed two weeks later via cervicotomy without incidents.

Role of cellular indices in predicting post-appendectomy abscess in children.

Up to 20% of advanced appendicitis cases can be complicated by postoperative abscesses, adding morbidity and mortality and prolonging hospital stays. This study examines the utility of two cellular indices as predictors of post-appendectomy abscess compared to cell counts. A diagnostic study was conducted on patients <15 years old who underwent appendectomy at a pediatric hospital between 2021 and 2022 (Reg. 2023/390894). Preoperative values of leukocytes, neutrophils, neutrophil-to-lymphocyte ratio (NLR= neutrophils/lymphocytes), and platelet-to-lymphocyte ratio (PLR= platelets/lymphocytes) were compared between patients with post-appendectomy abdominal abscess (PAA) and those without this complication (NPAA). The area under the ROC curve (AUC) was used to establish the predictive capacity of each parameter for PAA. A total of 89 patients with PAA and 93 NPAA children were included.

Derived neutrophil-to-lymphocyte ratio (dNLR) as a diagnostic biomarker of pediatric acute appendicitis.

Appendicitis stands as the most common surgical emergency in pediatric populations. Despite the existence of numerous diagnostic biomarkers, their utility is constrained by limitations in cost-effectiveness, potentially leading to therapeutic delays. This research aims to determine the diagnostic accuracy of the derived neutrophil-to-lymphocyte ratio (dNLR) in appendicitis. Although its role in this context has been recently described, this is the first study to compare its performance against acute-phase reactants routinely employed in clinical practice. Following approval from the Research Committee (2023/390894), a diagnostic study was conducted including patients under 15 years old undergoing surgery for acute appendicitis (AA) and those presenting with non-surgical abdominal pain (AP).

Superior Vesical Fissure as an Incomplete Form of Bladder Exstrophy: A Case Report with Clinico-Pathological Correlation and a Comprehensive Literature Review.

Multiple variants of classic bladder exstrophy have been described, all of them infrequent. Superior vesical fissure is a mild variant of this pathology in which genital involvement is scarce or absent. To date, there are only isolated reports of this entity. We report a full-term female patient of Arabian descent with a clinical and radiological diagnosis of superior vesical fissure that was surgically corrected in our center with a favorable evolution. Histological study, supported by immunohistochemical techniques, showed squamous and transitional epithelium and discrete chronic inflammation. Our literature review identified 26 reports of superior vesical fissure (including ours), with high heterogeneity in terms of clinical characterization and associated malformations and with only two histological reports. The clinical evolution of the patients reported in the literature was favorable, with lower morbidity and mortality than in classical forms of bladder exstrophy.

Antibiotic treatment of post-appendectomy abscesses in children, regardless of size: a twelve years' experience.

Intra-abdominal abscesses are a common issue after appendectomy. Antibiotics have shown efficacy in treating smaller abscesses, while larger ones have traditionally been treated with drainage. This study assesses the efficacy of antibiotics for post-appendectomy intra-abdominal abscess (PAA) in children regardless of size. Case-control study of children with PAA admitted at our hospital from 2010 to 2022. The efficacy of antibiotics was compared between abscesses less and more than 6 cm in diameter. The Institutional Review Board has approved this study. A total of 1766 appendectomies were performed from 2010 to 2022 with an incidence of PAA of 5% (n = 89): age 9.3 IQR 5.8, 63% male (n = 56). Sixty-seven patients presented with a ≤ 6 cm abscess (controls) and 22 children had a > 6 cm PAA (cases). Length of intravenous antibiotics were higher in cases (15 IQR 7 days) than controls (12 IQR 4 days), p = 0.003. The efficacy of antibiotics in controls was 97% whereas 86.4% in cases (p = 0.094), reoperation was needed in 2/67 controls and 3/22 cases, with no differences in complications or readmission. The length of stay was longer in cases (15 IQR 6 days) than controls (13 IQR 5 days), p = 0.042. Antibiotics seem a safe treatment for PAA in children regardless of the size. However, this approach is associated with a longer period of intravenous antibiotics and hospital stay, although not with a higher rate of therapeutic failure, complications or reoperations.
