Background: Dental caries remain a major public health issue among Italian children, with prevalence exceeding 60% in specific subgroups and marked socioeconomic gradients. Objectives: This multicenter study aimed to describe baseline caries experience, malocclusions, and oral hygiene status in pediatric populations residing in three Italian regions and to develop and preliminarily evaluate the feasibility of an integrated care pathway for the prevention and management of caries and malocclusions. Materials and Methods: Within the CCM 2024 program (ID 10), a cross-sectional baseline assessment was conducted on 795 children aged 6–11 years, examined in school settings and via mobile dental units. Caries experience was assessed using the dmft/DMFT indices and International Caries Detection and Assessment System (ICDAS) criteria. Malocclusions were evaluated using the Index of Orthodontic Treatment Need (IOTN). Oral hygiene was assessed through standardized clinical indices. The proposed care pathway comprises three tiers: (1) universal, school-based oral health education; (2) targeted clinical preventive and interceptive interventions; and (3) telemedicine/AI-supported follow-up for high-risk children. Descriptive and multivariable statistical analyses were performed. Results: At baseline, overall caries burden was low. No statistically significant differences in dmft/DMFT were observed between males and females. A non-significant trend toward higher caries indices was found among children with a positive breastfeeding history. By contrast, oral hygiene level was strongly associated with caries indices: children with insufficient hygiene had the highest dmft/DMFT, those with moderate hygiene showed intermediate values, and those with optimal hygiene presented the lowest caries experience. In multivariable models, oral hygiene emerged as the main independent predictor of dmft/DMFT. Conclusions: In this low-caries cohort, oral hygiene was confirmed as the principal modifiable determinant of caries risk. A tiered, school- and community-based care pathway focused on hygiene promotion, early screening, and minimally invasive clinical interventions appears feasible at baseline and may be scalable, with the aim of reducing the burden of caries and malocclusions and improving equity in pediatric oral health.

Background/Objectives: Small airway dysfunction (SAD) may occur early in children with Mycoplasma pneumoniae pneumonia (MPP), but pulmonary function testing is often deferred until clinical stabilization and may be limited by poor cooperation. Early risk stratification may therefore help identify children who warrant further testing. We aimed to identify early predictors of subsequent spirometry-defined SAD and to develop an internally validated risk-stratification model in hospitalized children with MPP. Methods: In this single-center retrospective cohort study conducted between July 2022 and July 2024, 172 hospitalized children with confirmed MPP were included. Clinical characteristics, immune-inflammatory indices, and chest computed tomography (CT) findings were collected during early hospitalization. Pulmonary function testing was performed after clinical stabilization, and SAD was defined as at least two of forced expiratory flow at 25%, 50%, and 75% of forced vital capacity being <65% of predicted values. Multiple imputation, LASSO selection, and multivariable logistic regression were used for model development and bootstrap internal validation. Results: SAD was identified in 76/172 children (44.2%). Wheezing, CT evidence of small airway involvement, and higher soluble interleukin-2 receptor levels were more common in children with SAD; wheezing remained independently associated with SAD. A model based on routine clinical and chest CT variables showed good discrimination (AUC, 0.885; optimism-corrected AUC, 0.869). Adding interleukin-17 provided limited incremental value. Conclusions: SAD was common in hospitalized children with MPP. An internally validated model based on readily available clinical and chest CT variables may help prioritize children for pulmonary function testing after clinical stabilization, whereas interleukin-17 added limited predictive value. External validation is required before broader clinical application. Full article

Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) represents a group of rare systemic autoimmune disorders marked by inflammation and damage to small- and medium-sized blood vessels. The clinical presentation of AAV is highly variable, ranging from isolated organ involvement to severe, life-threatening multisystem disease, posing significant challenges in diagnosis, treatment, and prognosis. Objective: To demonstrate the clinical heterogeneity and different outcomes in three pediatric cases of ANCA-positive disease and emphasize the importance of integrating clinical findings with laboratory and imaging investigations for accurate diagnosis. Methods: We present three pediatric patients (ages 12–15 years) with ANCA-positive results but distinct clinical presentations, evaluated at the Children’s Emergency Hospital “Louis Turcanu”, Timisoara, between 2020 and 2024. All cases were investigated according to EULAR/PRINTO/PReS criteria for pediatric vasculitis. Results: Case 1 (PR3-ANCA positive) developed severe multi-organ involvement, including granulomatosis with polyangiitis (GPA) with pulmonary hemorrhage, pericarditis, thrombotic events, and renal impairment, requiring intensive immunosuppression with cyclophosphamide, rituximab, and mycophenolate mofetil, ultimately developing chronic kidney disease stage 3a. Case 2 (BPI-ANCA positive) presented with purpuric lesions and painless joint swelling, responding favorably to corticosteroid therapy with subsequent remission. Case 3 (MPO-ANCA) manifested as polyarticular arthritis without other organ involvement and was ultimately diagnosed as seronegative juvenile idiopathic arthritis (JIA), achieving complete remission with adalimumab therapy. Conclusions: This case series highlights the diverse clinical and biological features of ANCA-positive conditions in children, emphasizing that ANCA positivity requires careful clinical correlation as it may indicate true vasculitis requiring aggressive treatment or alternative diagnoses such as JIA with incidental ANCA positivity. Tailored therapeutic strategies based on clinical presentation and continued research are essential to improve patient outcomes. Full article

Objectives: We aimed to assess fractional exhaled nitric oxide (FeNO) and spirometry in pediatric patients with inflammatory bowel disease (IBD) and relate these parameters to disease activity, duration, and current treatment. Methods: This prospective case–control study included 161 subjects: children with newly diagnosed, active IBD (N = 55), children in clinical remission (N = 53), and healthy controls (N = 53). FeNO was measured using a chemiluminescent analyzer, and pulmonary function was assessed by spirometry. Results: FeNO was higher in patients with IBD than in controls (p = 0.025) and positively correlated with CRP (ρ = 0.22; p = 0.027). Respiratory function measured by spirometry in children with IBD was preserved. No association was found between respiratory parameters, disease activity, and duration. The correlation between FeNO and aminosalicylate treatment was of borderline significance (ρ = 0.28; p = 0.052). Conclusions: Children with IBD, although having normal pulmonary function measured by spirometry, do have increased FeNO, which is positively correlated with CRP. FeNO reflects systemic inflammation, but its role as a clinical marker of disease activity or relapse remains uncertain. Full article

Background: Severe asthma exacerbations remain a major cause of pediatric intensive care unit (PICU) admissions, particularly in early childhood. Objective: To describe the demographic characteristics, clinical features, management strategies, and short-term outcomes of children admitted to the PICU with severe acute asthma exacerbations. Methods: A retrospective descriptive study was conducted of pediatric patients aged 1–14 years with severe acute asthma requiring PICU admission at King Salman Medical City, Madinah, Saudi Arabia (January 2023–October 2024). A total of 73 patients were included. Data included demographics, risk factors, medical history, clinical presentation, management, and outcomes. Results: The mean patient age was 4.6 years, with most (57.5%) aged 1–5 years. Males comprised 56.2% of cases. WHO BMI-for-age z-score assessment revealed a bimodal nutritional distribution: 27.9% of patients were underweight, including 20.6% with severe underweight, while 29.4% were overweight or obese; 42.6% had normal nutritional status. Severe undernutrition was concentrated in the 1–5-year age group, whereas obesity predominated in the 6–10-year age group. A family history of asthma was noted in 54.8% of patients; 16.4% had prior COVID-19 infection. Early symptom onset and delayed diagnosis were common. Poor asthma control was documented in 60.3%, with low medication adherence (9.6%) and limited aerochamber use (13.7%). The most frequent presenting symptoms were dyspnea, cough, and wheezing. Management followed evidence-based protocols: systemic corticosteroids and bronchodilators were first-line therapies. The mean PICU stay was 3.1 days and the mean hospital stay was 8.1 days. No mortality or major complications occurred; 93.2% of patients were discharged in good health. Conclusions: Severe pediatric asthma requiring PICU admission is associated with early symptom onset, a bimodal pattern of nutritional risk encompassing both undernutrition and overweight/obesity, family history of asthma, and inadequate outpatient management. These descriptive findings highlight the need for age-adjusted nutritional screening, enhanced medication adherence support, and targeted outpatient education to reduce avoidable PICU admissions.

Background/Objectives: The prevalence of developmental dysplasia of the hip (DDH) in adolescent idiopathic scoliosis (AIS) remains unclear, partly because of differences in diagnostic criteria and measurement accuracy. Additionally, spinopelvic alignment and skeletal maturation may affect radiographic assessment of acetabular morphology in patients with AIS. This study aimed to clarify the prevalence of DDH in Japanese patients with AIS using standardized radiographic assessment and to compare conventional and age-adjusted diagnostic criteria for DDH. Methods: This cross-sectional study included 602 Japanese patients aged 10–18 years with AIS. Patients with inadequate radiographs, including those with pelvic rotation and lateral inclination, were excluded to improve measurement accuracy. DDH was defined using two criteria: (1) conventional (lateral center-edge angle <20°) and (2) age-adjusted thresholds (<15° for <15 years and <18° for ≥15 years). Radiographic parameters were compared between patients with and without DDH. A multivariate logistic regression analysis was performed to identify factors independently associated with DDH. Results: The prevalence of DDH in AIS was 5.6% (34/602) using the conventional criterion and 1.5% (9/602) using the age-adjusted criteria. Patients with DDH showed significantly lower acetabular coverage, with a lower lateral center-edge angle and acetabular head index and higher Sharp and Tönnis angles than those without DDH (all p < 0.01). No significant difference in the main curve Cobb angle was observed between the groups. A younger age was independently associated with DDH, whereas sex and the main curve Cobb angle were not. Conclusions: The prevalence of DDH in Japanese patients with AIS varies substantially depending on the diagnostic criteria. Standardized radiographic evaluation with exclusion of pelvic rotation provides a reliable estimate. These findings highlight the importance of evaluating acetabular morphology on standing whole-spine radiographs in patients with AIS while considering skeletal maturation and spinopelvic alignment.

Objectives: The aim of the study was to assess the prevalence, severity and treatment needs of molar incisor hypomineralization (MIH) among a cohort of children in Lebanon. Methods: A cross-sectional study was performed in Akkar district in northern Lebanon on 1237 school children between 10 and 12 years old (mean age 11.11 ± 0.80 years) who were recruited from eight private schools. Clinical evaluations were performed after teeth cleaning and drying using sterile gauze. Examiners assessed all teeth present in the oral cavity using the MIH index of the EAPD. If MIH was diagnosed, a further grading was made according to the MIH-TNI index. Results: In total, 212 children (17.14% [95% CI:15.0, 19.2]) were diagnosed with MIH. Of these, 200 children with completed documentation were included in the further statistical analysis. Out of the affected cases, mild lesions were the most common at 41% (n = 82). Although males exhibited higher cumulative numbers of affected teeth (52.5%, n = 267), with notably greater proportions in moderate (17.7%) and severe (16.7%) cases, the difference between genders was not statistically significant (p = 0.069). Treatment needs increased with severity, in which mild lesions primarily required preventive care (41.0%), while moderate lesions required restorative treatments (34.0%); in contrast, severe lesions (25.0%) often necessitated extensive interventions, such as crowns, pulp therapies or even extractions. Although descriptive patterns suggested an increase in more complex treatment needs in older age groups, the association was not statistically significant (p = 0.26). Conclusions: The prevalence of MIH observed in this cohort study aligns with internationally reported values. Early detection, preventive management, and timely restorative interventions are essential to minimize the long-term impact of MIH. Full article

Background/Objectives: Advances in paediatric care have increased the survival of children with severe neurological impairment, often accompanied by complex disability, multimorbidity, and a substantial treatment burden. Determining whether interventions provide meaningful benefit to the child is ethically challenging, particularly when decision-making is shared between parents and clinicians, while the child has limited capacity to participate directly in decision-making. This paper examines the guiding question “what’s in it for the kid?” as a means of strengthening child-centred ethical deliberation alongside established frameworks. Methods: We undertook a conceptual bioethical analysis informed by clinical experience in an inner city tertiary public hospital. The analysis focuses on children with severe neurological impairment and medical complexity. The paper critically examines how the guiding question aligns with and extends key ethical constructs, including shared decision-making, the Zone of Parental Discretion, the Best Interests Standard, and care ethics. Clinical scenarios are used illustratively to demonstrate application in practice. Results: Existing ethical frameworks form an important foundational structure for complex decision-making. The question “what’s in it for the kid” translates ethical principles into a practical moral prompt that centres the child as the subject of decision-making. It facilitates clearer consideration of risks, benefits meaningful to the child and lived experience and helps to distinguish the child’s interests from those of parents and clinicians. Its simplicity enhances accessibility and supports consistent use in complex, high-stakes decisions. Conclusions: “What’s in it for the kid?” is a pragmatic and accessible ethical prompt that complements established frameworks by translating them into clinically usable practice. It promotes explicit, child-focused deliberation and supports a more transparent and child-centred evaluation of benefit and burden, particularly in contexts of uncertainty and medical complexity.

Background/Objectives: Congenital esophageal stenosis (CES) is a rare condition that may present with feeding difficulties in infancy, often becoming evident during weaning. We report a case of CES presenting with progressive dysphagia during the introduction of solid foods. Methods: Clinical evaluation, contrast esophagography, endoscopy, and magnetic resonance imaging were performed to characterize the stenosis and guide management. Results: Imaging revealed a fixed narrowing of the mid-distal esophagus with minimal passage of contrast and proximal dilatation. Endoscopy confirmed a non-traversable intrinsic stenosis with macroscopically normal mucosa. The patient underwent three endoscopic dilation sessions under general anesthesia using Savary-Gilliard bougies with progressive diameters (3–5 mm, 3–7 mm, and 7–11 mm). No major procedural complications occurred. At 2-month follow-up after the last dilation, feeding was appropriate for age, dysphagia had improved, and growth was regular. Conclusions: CES should be suspected in infants with feeding difficulties that worsen during weaning, particularly when symptoms are resistant to anti-reflux therapy. Endoscopic dilation can improve feeding tolerance, although repeated and staged sessions may be required. The role of adjunctive therapies such as topical budesonide remains uncertain. Full article

Objective: In addition to hyperoxia, inflammation and infection contribute to the pathogenesis of retinopathy of prematurity (ROP). However, the differential effects of specific bacterial pathogens on ROP development remain unclear. This study aimed to evaluate the association between sepsis due to Gram-positive and Gram-negative bacteria and the development and severity of ROP. Materials and Methods: Infants at risk for ROP, defined as those with birth weight ≤1500 g or gestational age ≤32 weeks, or those with birth weight >1500 g or gestational age >32 weeks who required cardiorespiratory support, were included in this retrospective study. Patients were categorised into no-ROP and any-stage ROP groups, as well as treatment-requiring and non-treatment-requiring ROP groups. The clinical characteristics, laboratory findings, and microbiological data were compared between the groups. Results: Among the 319 enrolled infants, 193 (60.6%) did not develop ROP, whereas 126 (39.4%) developed any-stage ROP. Clinical early-onset sepsis, clinical and proven late-onset sepsis, and increased frequency of late-onset sepsis episodes were significantly associated with any-stage and treatment-requiring ROP (p < 0.05). In multivariate analysis, both Gram-positive (OR 2.36, 95% CI 1.2–4.6, p = 0.012) and Gram-negative bacterial sepsis (OR 3.56, 95% CI 1.5–8.3, p = 0.004) were independently associated with any-stage ROP. In addition, Gram-positive bacterial sepsis (OR 4.4, 95% CI 1.1–16.9, p = 0.031) was independently associated with treatment-requiring ROP. Conclusions: Gram-positive bacterial sepsis was associated with both any-stage ROP and treatment-requiring ROP, whereas Gram-negative bacterial sepsis was associated with any-stage ROP only. These findings support the potential role of pathogen-specific inflammatory processes in ROP development and progression. Further prospective studies incorporating detailed inflammatory and oxygenation parameters are required to clarify these relationships. Full article

Background/Objectives: Asthma, one of the most common chronic diseases in childhood, and acute bronchiolitis, a leading cause of hospitalization in early childhood, remain significant contributors to morbidity and mortality. Methods: This retrospective cohort study evaluated the efficacy and safety of intravenous magnesium sulfate (IV MgSO₄) as a secondary treatment in pediatric patients with acute asthma exacerbation unresponsive to first-line therapy and in patients with acute bronchiolitis unresponsive to supportive care. A total of 450 patients aged 6 months to 18 years, including 252 with acute asthma exacerbation and 198 with acute bronchiolitis, were included. Results: Significant improvements in peripheral capillary oxygen saturation were observed after IV MgSO₄ administration in both groups (p < 0.001). In the acute asthma exacerbation group, IV MgSO₄ also significantly reduced tachypnea compared to the acute bronchiolitis group (p < 0.001). No adverse effects related to IV MgSO₄ were observed. Conclusions: These findings suggest that IV MgSO₄ may be both beneficial and safe as an early secondary treatment in acute asthma exacerbations. Full article

Background/Objectives: The impact of postnatal CMV infection in extremely premature newborns is poorly characterized. We aimed to determine the impact and outcomes of postnatal CMV infection in a population of extremely premature newborns of gestational age of less than 29 weeks hospitalized in the Department of Perinatology, Division of Gynecology, University Medical Center Ljubljana. Methods: We included all extremely premature newborns of gestational age of less than 29 weeks treated in the Department of Perinatology between December 2022 and December 2024. Newborns were screened for CMV infection at set timepoints and congenital infection was excluded with PCR testing. Additional PCR testing for CMV was performed if newborns developed clinical features suspect for postnatal CMV infection. Clinical characteristics and treatment outcomes of newborns were noted. Mothers of infected newborns had their CMV serostatus determined. Results: In total, 63 extremely premature newborns were included, and 14 newborns had confirmed postnatal CMV infection. Postnatal CMV infection was associated with hepatosplenomegaly and lower platelet and leukocyte counts compared to controls. We found no association between postnatal CMV infection and other neonatal comorbidities. Conclusions: In our study, postnatal CMV infection was associated with a more severe and prolonged clinical course of extremely premature newborns compared to uninfected controls; however, in multivariable analysis, the association with a prolonged length of stay was no longer statistically significant. The results suggest that preventing postnatal CMV infection in this population is important. Full article

Background/Objectives: This study aims to compare the oral health-related quality of life (OHRQoL) of children with molar incisor hypomineralisation (MIH) and their parents with that of an age- and caries-matched control group, and to evaluate the long-term impact of dental rehabilitation on OHRQoL. Methods: A total of 30 children aged 8–12 years were included, with 15 participants in the MIH group and 15 in the control group. OHRQoL was assessed using the Pediatric Oral Health-Related Quality of Life (POQL) scale. Data were obtained at baseline and at 3, 6, and 12 months after treatment. Statistical analyses included a chi-square test, independent samples t-test, Mann–Whitney U test and Friedman test, according to data distribution. Results: Baseline POQL scores were significantly higher in the MIH group compared with the control group for both children and parents (p = 0.020 and p = 0.036, respectively). Among subscales, emotional functioning scores in children and role and physical functioning scores in parents were significantly higher in the MIH group (p = 0.027 and p = 0.032, respectively). Following dental rehabilitation, POQL scores significantly decreased in both groups (p < 0.001), and this improvement was maintained throughout the 12-month follow-up period. Conclusions: MIH has a negative impact on the OHRQoL of both children and parents, regardless of caries experience.

Background/Aim: While improvements in oral health can sometimes lead to improvements in systemic diseases, certain systemic diseases such as heart disease require consideration during dental treatment. In clinical pediatric dentistry, dental professionals may encounter the pediatric patient with systemic diseases, and should consult with physicians regarding the overall health status of their patients with systemic diseases before dental procedures. Materials and Methods: We reviewed the responses to letters of inquiry made to external medical institutions regarding the overall physical condition of patients during a 5-year period (2021–2025). The survey items were the gender, age, aim of letter, systemic disease, and physician responses and instructions. Result: A total of 48 letters of inquiry were found, of which 34 were initial confirmations and 14 were reconfirmations. In children aged ≤5 years, the common aim was oral management or caries treatment, and the proportion of surgical procedures increased with age. Among the systemic diseases involved, the diseases of the circulatory system such as congenital heart disease were the most common, with 70% of initial confirmations leading to premedication with antibiotics prior to invasive dental procedures. Although many responses remained unchanged upon reconfirmation, the responses for some patients changed. Conclusions: This study shows the importance of dental professionals consulting with physicians regarding the health condition of patients with systemic diseases before oral management. Furthermore, a single confirmation is insufficient, and the information must be regularly updated. Full article

Background/Objectives: Postoperative agitation (PA) and postoperative pain in pediatric patients following sevoflurane anesthesia are challenging clinical scenarios. This study aimed to evaluate the effects of intraoperative dexmedetomidine infusion compared to fentanyl infusion on the prevention of postoperative agitation and analgesic efficacy in children undergoing tonsillectomy and/or adenoidectomy. Methods: After ethical committee approval, a total of 85 pediatric patients (age range: 2–13 years) in the ASA I-II group were included in the study. Patients were randomized into two groups: the dexmedetomidine group (Group D, n = 40) and the fentanyl group (Group F, n = 45). Postoperative pain was monitored in the recovery unit (PACU) using the FLACC (face, legs, activity, cry, consolability) scale, and agitation was monitored using the PAED (pediatric anesthesia emergence delirium) scale. FLACC and PAED were monitored at 5, 10, 15, 30 min, and 2 and 4 h postoperatively. Results: Demographic data and surgical durations were similar between groups (p > 0.05). The dexmedetomidine group had lower FLACC pain scores at 10 and 15 min (uncorrected trends), but only the difference at 30 min remained statistically significant after Bonferroni correction (p = 0.0001; Cohen’s d = 0.85). Although PAED scores were numerically lower in Group D, no statistically significant difference was found. While an observational trend toward lower agitation was noted, it did not reach statistical significance. Extubation times and hemodynamic parameters were similar in both groups. Conclusions: The intraoperative use of dexmedetomidine in tonsillectomy and adenoidectomy procedures provides superior analgesia compared to fentanyl, particularly in the first 30 min postoperatively, without prolonging recovery time.

Objective: Rapid-sequence magnetic resonance imaging (rMRI) has emerged as a radiation-free alternative to computed tomography (CT) in pediatric neuroimaging. This study aimed to evaluate the diagnostic utility, clinical consequences, and subgroup-specific differences in pediatric patients undergoing rMRI for emergency neurosurgical indications. Methods: We conducted a retrospective, single-center study of 158 rMRIs in 73 pediatric patients who underwent rMRI between January 2017 and December 2023 due to suspected complications of hydrocephalus and brain tumors. A short MRI protocol (195 s) including FLAIR BLADE and T2 HATSE sequences was employed. Patients were categorized into tumor non-related and tumor-related hydrocephalus groups. Results: A total of 158 rMRIs in 73 pediatric patients were included. The mean age was 7.09 ± 4.63 years, with 69.6% male patients. Ventricular size monitoring was the most common rMRI indication (96.2%). Clinical consequences followed in 52.5% of cases, including surgical interventions (21.5%) and shunt valve adjustments (37.3%). Sedation was required in only 5.1% of patients. Only 1.9% required follow-up CT. Statistically significant intergroup differences were found in drainage type (p < 0.001), diagnosis (p < 0.001), and need for follow-up MRI (17.4% in the tumor-related hydrocephalus group vs. 4.5% in the tumor non-related hydrocephalus group; p = 0.014). Conclusions: rMRI is a safe, efficient, and effective alternative to CT for emergency neuroimaging in pediatric patients with hydrocephalus, tumors, or shunts. It facilitates timely clinical decision-making while avoiding radiation exposure. Our findings support broader implementation of rMRI protocols, particularly for patients requiring ongoing tumor surveillance. Full article

Background/Objectives: Musculoskeletal pain represents a frequent and increasingly recognized health issue during adolescence. During this developmental phase, daily habits such as prolonged sitting, sedentary behaviors and the adoption of non-neutral postures may contribute to spinal overload and pain symptoms. This study contributes to the existing literature by focusing on concrete postural behaviors in real-life daily situations, an aspect that is still underexplored despite its relevance for musculoskeletal health. The aim of this study was to investigate the associations between daily habits, postural behaviors and the presence of back and neck pain. Methods: A cross-sectional study was conducted on a sample of 70 adolescents aged 10–20 years. Data were collected using the Back Pain and Body Posture Evaluation Instrument for Children and Adolescents (BackPEI-CA), administered online. Descriptive statistics and chi-square tests with effect sizes (Cramer’s V) were used to examine associations between postural behaviors, lifestyle factors, and pain outcomes, providing an inferential assessment beyond simple descriptive analysis. Results: Significant associations were found between gender and back pain, sitting posture during daily activities (writing at the desk and talking with friends) and back pain, with flexed or asymmetrical postures more frequently reported among participants with pain, and between back and neck pain (p < 0.05). Conclusions: The findings highlight the relevance of gender and daily postural behaviors as factors associated with musculoskeletal pain in adolescents. By identifying posture-specific behaviors linked to pain, this study provides preliminary evidence that can inform targeted preventive strategies and guide future research on modifiable daily habits in youth.

Background/Objectives: Auditory processing disorders (APDs), defined as impaired neural processing of acoustic stimuli despite normal peripheral hearing, often co-occur with neurodevelopmental disorders (NDDs) and may contribute to language, attentional, and learning difficulties. Emerging evidence suggests that shared neurotransmitter systems may represent a common neurobiological substrate underlying these conditions. The aim of this study is to integrate current evidence on glutamatergic, GABAergic, and monoaminergic systems in neurodevelopmental and auditory processing disorders in children and adolescents, and to evaluate the hypothesis that shared neurotransmitter dysregulation may underlie their clinical overlap. Methods: A narrative review of the literature was conducted through electronic searches in PubMed and Embase up to 31 December 2025, using keywords related to neurotransmitters, NDDs and APDs. Results: Available evidence indicates that an imbalance between excitatory glutamatergic and inhibitory GABAergic neurotransmission has been proposed as a central mechanism in NDDs and may also contribute to auditory processing difficulties through altered neural synchrony, sensory gating and temporal auditory coding. Findings collectively suggest the hypothesis of shared neurotransmitter dysregulation across NDDs and APDs. Conclusions: Auditory processing difficulties may represent sensory-level expressions of shared neurochemical vulnerability across neurodevelopmental conditions. Future longitudinal and multimodal studies are needed to clarify causal relationships and to identify clinically useful biomarkers. Full article

Background and aims: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease among children. Our study aimed to evaluate the prevalence of hypogammaglobulinemia among pediatric patients with AD and to characterize the clinical and laboratory findings of patients diagnosed with AD and hypogammaglobulinemia. Method: The electronic files of 1850 patients aged 0–18 years diagnosed with AD between 2020 and 2022 in the Pediatric Immunology and Allergy Clinic of Bursa Medical Faculty City Hospital were retrospectively analyzed. During this period, all patients newly diagnosed with atopic dermatitis at our clinic were systematically screened for their serum immunoglobulin (Ig) levels (IgG, IgA, and IgM) at the time of initial presentation. We included 200 AD patients with hypogammaglobulinemia. Disease severity was classified using the Scoring Atopic Dermatitis (SCORAD) index. Multivariate logistic and linear regression analyses were performed to identify independent determinants of disease severity, considering age, sex, eosinophil counts, total IgE, food allergies, and baseline immunoglobulin levels. Results: The prevalence of hypogammaglobulinemia among the 1850 screened children with AD was 10.8% (200/1850). Of the 200 patients included in this study, 128 (64%) were male, and 72 (36%) were female. The median age at first clinic presentation was 8 months (interquartile range (IQR) 25–75%: 5–16). According to the Scoring Atopic Dermatitis (SCORAD) index, AD severity was mild in 150 (75%) patients and moderate-to-severe in 50 (25%). Food allergy sensitization was present in 72 (36%) patients. Patients with moderate-to-severe AD had significantly lower IgG (300 vs. 374 mg/dL; p < 0.001; r = −0.346), IgA (10 vs. 14 mg/dL; p = 0.004), and IgM (38 vs. 51 mg/dL; p = 0.001) levels when compared with those with mild disease. Multivariate logistic regression confirmed that lower IgG was the only immunoglobulin independently associated with moderate-to-severe AD (OR = 1.97 per 100 mg/dL decrease; 95% CI: 1.15–3.39; p = 0.013), while food allergy was the strongest independent predictor of the SCORAD index (β = +11.97; p < 0.001). None of the patients received intravenous immunoglobulin (IVIG) treatment. Of the 142 patients who underwent serial serum immunoglobulin measurements, 56 (39%) achieved age-appropriate normal IgG levels, while hypogammaglobulinemia persisted in 86 (61%). Conclusions: We found a higher frequency of hypogammaglobulinemia in patients with AD in our study, as compared with previously reported rates of THI in children from the general pediatric population. Although our study showed an increase in IgG levels during the follow-up period in many patients, it emphasizes the need for long-term immunological monitoring, especially in patients with moderate-to-severe AD.

Background/Objectives: Children born very preterm (VP) are at increased risk of later emotional and cognitive difficulties, including anxiety symptoms during childhood. Altered early brain development, particularly within subcortical circuits involved in emotional regulation, may contribute to this vulnerability. This study aimed to assess anxiety symptoms in preschool-aged children born VP, examine their relationship with cognitive performance, and determine whether neonatal brain volumes at term-equivalent age (TEA) were associated with later anxiety symptoms. We also explored whether cognition mediated the association between neonatal striatal volumes and anxiety. Methods: We conducted a longitudinal cohort study of infants born at ≤32 weeks of gestation and/or with a birth weight ≤1500 g admitted to a tertiary neonatal intensive care unit between 2018 and 2021. At 4–6 years of age, anxiety symptoms were assessed using the Child Behavior Checklist (CBCL) Anxiety Problems subscale, and cognitive performance was evaluated with the Wechsler Preschool and Primary Scale of Intelligence-IV (WPPSI-IV). Neonatal magnetic resonance imaging performed at TEA was used to obtain regional brain volumetric measures. Associations were analyzed using adjusted linear regression, interaction-based volumetric modeling, path analysis, and receiver operating characteristic analysis. Results: Ninety-five children were included, and 24 (25.3%) showed clinically relevant anxiety symptoms according to the CBCL Anxiety Problems subscale. Higher WPPSI-IV scores were associated with lower anxiety scores (β = −0.183; p = 0.042). The best-fitting MRI model included caudate volume, putamen volume, and their interaction, with a significant association between the putamen–caudate interaction and anxiety symptoms (β = −17.807; p < 0.001). In the path model, both cognition and the putamen–caudate interaction were directly associated with anxiety, whereas the indirect effect through cognition was not significant. The final MRI model showed acceptable discrimination for clinically relevant anxiety (AUC = 0.796). Conclusions: Anxiety symptoms were frequent in preschool-aged children born VP and were associated with lower cognitive performance. Neonatal striatal volumetric organization, particularly the interaction between the putamen and caudate volumes, was independently associated with later anxiety symptoms, suggesting that cognitive and early neural factors may contribute to anxiety risk through parallel rather than mediated pathways.

Background: Pulmonary arterial hypertension is a rare but life-threatening condition in children, with hereditary forms often being linked to mutations in genes such as bone morphogenetic protein receptor type 2 (BMPR2), caveolin 1 (CAV1), and potassium channel subfamily K member 3 (KCNK3). Among these, CAV1 mutations are associated with severe disease phenotypes, though cases resulting from de novo heterozygous CAV1 mutations with multi-system involvement remain rarely reported. The CAV1 mutation (c.424C > T, p.Q142X) disrupts caveolin-1 function, leading to dysregulated pulmonary vascular remodeling and multi-system abnormalities. Methods: This was a retrospective case study of a pediatric patient with hereditary PAH. The patient was followed at our hospital from initial presentation until death. Clinical data were collected from medical records, including physical examinations, laboratory tests, echocardiography, chest X-ray, computed tomography pulmonary angiography (CTPA), and genetic analysis. The patient was treated sequentially with various PAH-targeted medications. This report also includes a review of the relevant literature on CAV1-associated PAH. Results: A female aged 3 years and 11 months was diagnosed with hereditary PAH associated with a de novo heterozygous CAV1 mutation (c.424C > T, p.Q142X). Both parents underwent genetic testing and were negative for the mutation, confirming its de novo origin. Clinical manifestations included special facial features, congenital telangiectasia, cutis marmorata (marbled skin), congenital cataract, hereditary lipodystrophy, and severe PAH. The patient presented with progressive exercise intolerance, syncope, and worsening dyspnea over nine years. Echocardiography revealed pulmonary hypertension with an estimated pulmonary artery systolic pressure of 69–105 mmHg, right heart enlargement, right ventricular hypertrophy, and moderate tricuspid regurgitation. Blood and urine metabolic screenings were normal. A chest X-ray showed progressive enlargement of the cardiac silhouette and bulging of the pulmonary artery segment. CTPA demonstrated pulmonary hypertension, secondary right heart dysfunction, decompensated right ventricular function, and mosaic perfusion in both lungs, suggestive of small arterial branch occlusion. Right heart catheterization was declined by the parents. Thus, the diagnosis of PAH was established based on clinical, echocardiographic, CTPA, and genetic findings. The patient was hospitalized four times and lost to follow-up from 2017 to 2023. She received sequential treatment with digoxin, hydrochlorothiazide, tadalafil, ambrisentan, selexipag, and treprostinil. Despite these therapies, pulmonary artery pressure continued to rise with progressive clinical deterioration. The patient ultimately died at 13 years of age due to a pulmonary hypertensive crisis and multiple organ failure following a severe episode of gastroenteritis. Conclusions: Despite aggressive treatment with multiple targeted reduced pulmonary artery pressure drug therapies, managing hereditary PAH caused by CAV1 mutations in children remains a significant challenge, with a high mortality rate. Early genetic diagnosis, regular follow-up, and individualized treatment are crucial. It requires the joint efforts of patients, parents, and healthcare providers. Full article

Background/Objectives: Child temperament and mastery motivation are key factors for future child competencies. Therefore, two purposes of this study were: (1) to compare temperament characteristics in children with global developmental delay (GDD) and typical development (TD); (2) to explore the relations among child temperament and mastery motivation in GDD and TD groups. This study design was cross-sectional. Methods: Participants included 26 children with GDD (ages 2–5) recruited from clinical settings in Central Taichung. A comparison group of 26 TD children, matched for sex and mental age, was subsequently enrolled through community advertisements and local early childhood centers. The participants were invited to our laboratory in order to conduct child development assessment using the Comprehensive Developmental Inventory for Infants and Toddlers, and their mothers were asked to fill in questionnaires, including the revised Dimension of Mastery Questionnaire (DMQ 18) with preschool version to assess mastery motivation and the Child Behavior Questionnaire—Short Form to obtain three dimensions of child temperament (surgency/extraversion, negative affect, effortful control). Correlations and hierarchical regressions were used to examine associations (p < 0.05, two-tailed). Results: Children with GDD exhibited higher extraversion and lower effortful control than children with TD, whereas no group difference was observed in negative affect. Domain-specific relationships between child temperament and mastery motivation were found in both the GDD and TD groups. Conclusions: These findings suggest that early childhood practitioners should consider children’s temperamental and mastery motivation characteristics, identify individual strengths and weaknesses, and design strength-based intervention strategies to promote engagement in daily activities within natural settings.

Background/Objectives: Early childhood caries (ECC) is a chronic inflammatory condition that may impose a systemic burden in pediatric patients. This study aimed to evaluate the association between dental caries severity, classified by dmft (decayed, missing, and filled teeth for primary dentition) scores, and preoperative systemic inflammatory markers derived from routine complete blood counts (CBC). Methods: This retrospective study included 159 children aged 36–71 months. Participants were categorized into three groups based on dmft scores: low (0–3), medium (4–8), and high (≥9). Hematological parameters and inflammatory indices, including neutrophil-to-lymphocyte ratio (NLR) and systemic immune-inflammation index (SII), were analyzed using one-way ANOVA with post hoc comparisons. Results: Significant differences were observed among dmft groups for neutrophil and lymphocyte percentages (p = 0.026 and p = 0.027) and lymphocyte count (p = 0.020). The medium severity group demonstrated higher neutrophil levels and lower lymphocyte values compared to the high severity group (p < 0.05). Although overall group differences for NLR and SII were not statistically significant (p > 0.05), both markers were significantly higher in the medium group than in the high group (p < 0.05). No significant differences were found in hemoglobin, RDW, or platelet parameters. Conclusions: A non-linear trend was observed, with relatively elevated inflammatory markers in the moderate dmft group. These findings suggest that systemic inflammation in ECC is more closely related to disease characteristics than to caries burden alone. CBC-derived parameters may provide supportive but limited value for assessing systemic inflammatory status in pediatric dental patients. Full article

Background: Atopic dermatitis (AD) is a chronic, relapsing inflammatory dermatosis that is characterized by pruritus, xerosis, and age-dependent clinical heterogeneity. Accurately diagnosing AD remains challenging due to the absence of specific biomarkers and the broad spectrum of conditions that may mimic its presentation. A wide range of inflammatory, infectious, and genetic disorders resemble AD, including seborrheic dermatitis, psoriasis, contact dermatitis, scabies, dermatophytosis, and nummular eczema, as well as rare immunodeficiency and metabolic conditions. This review summarizes the evolution of the clinical features of pediatric AD across infancy, childhood, and adolescence, with a focus on key differential diagnoses. Recognizing age-specific patterns and potential mimickers is essential for improving diagnostic accuracy and guiding appropriate management in pediatric AD. Methods: This study was designed as a narrative review. A structured literature search was conducted of PubMed/MEDLINE for studies published between January 2001 and March 2026 using predefined keywords related to AD, childhood, diagnosis, and differential. Clinical trials, randomized controlled trials, systematic reviews, meta-analyses, and guidelines or consensus documents were included. Studies focusing exclusively on adults or lacking clinical relevance were excluded. A qualitative synthesis was performed due to the heterogeneity in study designs and outcomes. Results: This review demonstrates that pediatric atopic dermatitis exhibits marked age-dependent clinical heterogeneity, with distinct morphological features and lesion distribution patterns across infancy, childhood, and adolescence. Furthermore, the substantial clinical overlap with a broad spectrum of inflammatory, infectious, and genetic disorders—combined with the absence of specific diagnostic biomarkers—significantly complicates accurate differential diagnosis and increases the risk of misclassification. Conclusions: The recognition of age-specific patterns and potential mimickers is essential for improving diagnostic accuracy and guiding appropriate management in pediatric AD. Full article

Background: Cardiac tamponade (CT) is a rare but life-threatening medical emergency caused by fluid accumulation in the pericardial sac, impairing cardiac filling and reducing output. More than 20% of CT cases are iatrogenic. CT is a recognized complication of central venous catheter (CVC) placement, with mortality rates in pediatric patients reported to reach 50%. Clinical presentation is often nonspecific, and echocardiography remains the diagnostic gold standard. Case report: We present two pediatric cases of CT due to late CVC migration, managed in the pediatric intensive care unit (PICU). The first case involved a 25-day-old neonate with short bowel syndrome who received prolonged parenteral nutrition via CVC. Four days after catheter insertion, the patient developed sudden cardiocirculatory collapse. The second case featured a 2-year-old child with Leigh syndrome who required mechanical ventilation and multimodal pharmacological therapy. Six days after CVC placement, the patient developed acute hemodynamic deterioration. In both cases, echocardiography confirmed CT, while chest radiography suggested intracardiac positioning of the catheter tip. Management and outcome: Emergency pericardiocentesis and advanced cardiopulmonary resuscitation were performed. Despite transient hemodynamic stabilization, both patients developed multiorgan failure with fatal outcomes. Conclusions: CT is a critical complication in pediatric patients with CVCs. Accurate verification of catheter tip position is essential, and intracardiac placement should be avoided. Any sudden clinical deterioration in a patient with a CVC should raise suspicion of late catheter migration and requires immediate life-saving intervention. Full article

Background/Objectives: The optimal timing of asymptomatic congenital pulmonary airway malformations (CPAM) is controversial. Early resection may reduce inflammation and scarring secondary to respiratory infections, but contemporary practice patterns are unknown. This study assesses trends in operative timing and approach over the past decade. Methods: A retrospective review was performed of 1934 CPAM patients in NSQIP-P undergoing resection (2012–2021). Trends in surgical approach and age at resection were assessed using Mann–Kendall tests. Multivariable logistic and linear regression were used to model the influence of age at operation on operative length, postoperative complications, and postoperative length of stay. Results: Thoracoscopic approach increased from 47.2% in 2012 to 80.8% in 2021 (p < 0.001). Median age at operation was 7.7 months. There was a downtrend in the open approach in patients ≤3 months old (tau = −0.511, p < 0.05) without a corresponding increase in VATS approach (tau = −0.11, p = 0.72). Instead, there was a statistically significant uptrend in all other age cohorts >3 months old in the VATS approach. After adjusting for confounders there was no difference in complication rates between age cohorts. Conclusions: Adoption of thoracoscopic resection for CPAM has substantially increased. Despite the reported benefits of earlier resection, the timing of surgical resection remains variable with most surgeries still occurring after six months of age. Additionally, the decline in open surgeries in patients ≤3 months may reflect a preference towards the VATS approach in a slightly older infant population. Further research is necessary to determine optimal timing for CPAM resection. Full article

Background/Objectives: The purpose of this study was to analyze the demographics and injury patterns of children with transportation-related non-fatal injuries occurring on public roads, streets and highways using a nationwide emergency department (ED) database. Methods: Data from the National Electronic Injury Surveillance System (NEISS) All Injury Program (AIP) 2005–2021 was used. Five transportation methods (motor vehicle occupant, bicyclist, pedestrian, motorcyclist, other) occurring on a public highway, street, or road were analyzed. Statistical analyses were performed with SUDAAN 11.0.01™ software to obtain national estimates. Results: There were an estimated 8,188,810 ED visits for traffic-related injuries in children; the median age is 14.3 years. Sex distribution was equal; 93.4% were discharged from the ED, and the head/neck was the most injured area (51.9%). The most common diagnoses were contusion (35.7%), strain/sprain (28.0%), internal organ injuries (13.3%), fracture (8.4%), lacerations (7.4%) and concussions (4.1%). Predictor variable of not being discharged from the ED was the presence of a fracture (OR = 119.7 [71.3, 200.7], p < 0.0001), injury to the trunk (OR = 3.2 [2.7, 3.8], p < 0.0001), a pedestrian (OR = 3.9 [2.8, 5.3], p < 0.0001), those <1.5 years old (OR = 4.3 [2.8, 6.6], p < 0.001), and males (OR 1.5 [1.4, 1.6], p < 0.0001). The greatest prevalence of head/neck fractures was in motor vehicle occupants (23.3%), upper extremity fractures in bicyclists (73.1%) and motorcyclists (49.2%), and lower extremity fractures in pedestrians (56.6%). Conclusions: This detailed study can be used to compare/contrast these injuries to other countries regarding road traffic injuries in children. This data can be used to assess the outcomes of prevention strategies introduced in the future. Full article

Background: Digital gaming is an integral part of children’s everyday lives and may relate to both cognitive development and psychosocial well-being. Although computational thinking is considered a key skill for navigating digital environments, limited research has examined how digital game addiction relates to computational thinking and well-being, particularly among children with chronic health conditions such as structural heart disease. Objectives: This study aimed to examine the associations among digital game addiction, computational thinking skills, and well-being among middle school children with structural heart disease and their typically developing peers. Methods: An exploratory correlational design was employed. The sample consisted of 30 children with structural heart disease and 25 typically developing peers aged 10–14 years. Data were collected using the Computational Thinking Skills Scale, the Digital Game Addiction Scale for Children, and the EPOCH Well-Being Scale. Relationships among variables were examined using correlation analyses. Results and Conclusions: Among children with structural heart disease, higher levels of digital game addiction were associated with lower creativity, collaboration, and overall computational thinking skills. Computational thinking skills were positively associated with selected dimensions of well-being, particularly connectedness and perseverance. In typically developing children, digital game addiction was negatively associated with several computational thinking dimensions, whereas perseverance and certain aspects of well-being were positively associated with computational thinking skills. Overall, digital game addiction showed limited associations with well-being in both groups. These findings suggest that the relationships among digital game addiction, computational thinking, and well-being may be complex and context-dependent. Given the exploratory correlational design and relatively small sample size, the results should be considered preliminary. Full article

Objectives: Parental health literacy plays a pivotal role in shaping caregiving practices and influencing their children’s health. The aim of this systematic review is to analyze studies examining health literacy among parents raising children under five, in relation to caregiving practices and children’s health outcomes. Methods: The research was conducted in accordance with PRISMA protocol. The sample of the study was determined by using the terms related to “health literacy” AND “parent” (OR “caregiver” OR “mother” OR “father”) AND “child” AND “measure” (OR “instrument” OR “tool” OR “questionnaire” OR “survey” OR “interview”) in ERIC, PUBMED, Scopus and WOS databases published between 2015 and 2024. Results: Of the 1726 results identified, 18 studies met the inclusion criteria. The reviewed studies on parental health literacy place particular emphasis on oral health literacy, nutrition/food literacy, vaccine literacy, and fever literacy. Conclusions: Based on the included studies, parents’ health literacy is generally found to be significantly associated with the adequate fulfilment of children’s care needs, the implementation of appropriate parenting practices, and the effective management of childhood illnesses (although findings regarding vaccination willingness are inconsistent). Overall, these associations may carry long-term implications for children’s health. Full article
