Introduction: In Romania, studies on the pediatric population regarding H. pylori infection or bacterial resistance to antibiotics are limited. Eradication treatment of this infection still raises important problems in medical practice. This study aims to compare the effectiveness of three eradication therapies used against H. pylori infection in the pediatric population. Methods: The prospective study enrolled children aged 6–17 years who were first diagnosed with H. pylori infection. Patients received a randomized treatment either the therapy with clarithromycin (CLR), the therapy with metronidazole (MTZ) or sequential therapy. The effectiveness of the eradication treatment was evaluated after 4–8 weeks from the end of the therapy by testing fecal antigen. Results: 149 patients were enrolled over 18 months. The eradication rates were 49.5% for the treatment scheme with proton pump inhibitor (PPI) + amoxicillin (AMO) + MTZ, 26.7% for PPI + AMO + CLR and 23.8% for sequential therapy. MTZ therapy was superior to CLR therapy, but sequential therapy was not. Side effects were recorded for PPI + AMO + CLR with 39.6%, followed by sequential therapy 37.7%, and only 22.6% for PPI + AMO + MTZ. Conclusions: Therapy with MTZ can achieve a higher eradication rate as a first-line treatment in the case of H. pylori infection. Taking into account that Romania is in an area with increased resistance to CLR, MTZ therapy could be a promising alternative.

Background: The ongoing military conflict in Ukraine has had a devastating impact on children’s health, exposing them to a range of illnesses. The aim of this study was to analyze the most common medical conditions among Ukrainian children since the beginning of the conflict, with a focus on identifying and understanding these problems in a wartime setting. Method: To assess the health status of affected children, we collected data from 422 pediatric patients who presented to the emergency department. The analysis included reviewing medical records, documenting the nature of illness, treatments administered, and the need for hospitalization. Results: Preliminary results indicate that interstitial pneumonia, contusions, gastroenterocolitis, and traumatic brain injury were the most common conditions. Of the 422 children studied, 80% received appropriate care without hospitalization, while 20% were admitted for further evaluation. Conclusions: Interstitial pneumonia was diagnosed in 23% of patients, highlighting the vulnerability of the respiratory system under conflict conditions. Contusions were predominant among musculoskeletal injuries, accounting for 81% of cases, and gastroenterocolitis was diagnosed in 46% of patients, reflecting the impact of poor living conditions.

The clinical relevance of food-specific IgG antibodies in pediatric gastrointestinal disorders remains controversial. Although current international guidelines discourage their use as standalone diagnostic tools, their significance within a broader immune–gut inflammatory framework has not been sufficiently explored. This study aimed to investigate associations between food-specific IgG reactivity, inflammatory and permeability biomarkers, microbiological findings, and abdominal ultrasound abnormalities in children with chronic gastrointestinal symptoms. Methods: (1) Children presenting chronic gastrointestinal symptoms associated with food-specific IgG polysensitization, elevated inflammatory and permeability biomarkers, and abdominal ultrasound abnormalities (number (n) = 196); (2) a symptomatic gastrointestinal group without the complete multimodal profile (n = 146); and (3) a control group with normal abdominal ultrasound findings and biomarkers within reference ranges (n = 210). All participants underwent food-specific IgG testing using a 216-antigen ELISA panel, abdominal ultrasound examination, and assessment of intestinal inflammatory and permeability biomarkers. Food-specific IgG antibodies were not interpreted as diagnostic markers of food allergy or food intolerance. Comparative analyses, correlation analyses, multivariable logistic regression, and receiver operating characteristic (ROC) analyses were performed. Results: Food-specific IgG polysensitization was significantly more frequent among children presenting the multimodal inflammatory profile compared with symptomatic and control groups (all p < 0.001). Reactivity predominantly involved gluten-containing cereals, dairy proteins, and mixed gluten–dairy patterns. Elevated fecal calprotectin, zonulin, and fecal histamine concentrations were more frequently observed in this subgroup, together with a higher prevalence of ultrasound abnormalities, including bowel wall thickening and mesenteric lymphadenopathy. Correlation analyses demonstrated significant associations between cumulative IgG burden and bowel wall thickness (r = 0.48, p < 0.001), while fecal calprotectin showed the strongest association with ultrasound abnormalities (r = 0.62, p < 0.0001). Multivariable logistic regression identified elevated calprotectin, increased zonulin, IgG polysensitization, and mixed gluten–dairy reactivity as independent predictors of pathological ultrasound findings. The integrated multimodal model demonstrated higher classification performance than isolated biomarkers. Conclusions: Children presenting chronic gastrointestinal symptoms, food-specific IgG polysensitization, inflammatory biomarker abnormalities, and ultrasound changes represented a multimodal clinical subgroup within the study population. These findings support evaluating food-specific IgG reactivity within a broader immune–gut assessment framework rather than as a standalone diagnostic biomarker. The observed associations should be considered exploratory and hypothesis-generating, requiring prospective validation and mechanistic investigation.

Background: Pediatric respiratory infections represent a leading cause of emergency department (ED) visits and hospitalizations. Chest X-rays are frequently used in their diagnostic evaluation, despite guideline recommendations advocating restrictive imaging strategies, particularly in young children with uncomplicated disease. Excessive imaging raises concerns regarding cumulative radiation exposure and inefficient resource utilization. Objectives: To quantify potentially unnecessary chest radiography use in hospitalized pediatric patients with respiratory infections and to identify age-related and diagnostic patterns suitable for targeted imaging optimization interventions. Methods: We conducted a retrospective observational study analyzing pediatric patients presented to the ED of a tertiary county hospital in Romania over a period of 12 months. Data regarding respiratory diagnoses, hospitalization status, patient age, and chest radiography utilization were extracted from electronic medical records. Results: Among more than 26,000 pediatric emergency presentations, 4139 children required hospitalization, of whom 1212 were diagnosed with respiratory infections. A total of 3414 chest radiographs were performed, with the highest imaging burden observed in children aged 0–4 years. Repeated imaging was common in interstitial pneumonia, bronchiolitis, and bronchial hyperreactivity. A strong negative correlation was identified between patient age and imaging frequency (r = −0.70, p < 0.001). Conclusions: Thoracic radiographs are disproportionately used in young children with respiratory infections, particularly in conditions with limited imaging indications. These findings provide an essential baseline for the development of targeted quality improvement interventions aimed at reducing unnecessary pediatric imaging.
