1. Rib suppression-based radiomics for diagnosis of neonatal respiratory distress syndrome in chest X-rays.
Using 138 neonatal CXRs, rib suppression significantly improved radiomics-based NRDS classification, with GBM AUC rising from 0.556 to 0.781 and LDA/LR achieving AUCs of 0.762/0.756 when combining features. Findings support the feasibility and added value of rib suppression preprocessing in pediatric radiomics.
Impact: Introduces and quantifies a practical preprocessing step—rib suppression—that yields meaningful performance gains in NRDS radiomics on CXR, potentially generalizable to other pediatric imaging tasks.
Clinical Implications: If externally validated, rib-suppression-enhanced radiomics could support earlier NRDS diagnosis and triage from plain CXR, reducing diagnostic uncertainty and potentially guiding timely respiratory support.
Key Findings
- Rib suppression improved validation AUC for GBM from 0.556 to 0.781.
- Combining pre- and post-suppression features yielded strong performance with LDA (AUC 0.762) and LR (AUC 0.756).
- Chronologically split training/validation demonstrated consistent gains across six machine learning models.
- Radiomics-based NRDS diagnosis from CXR is feasible and enhanced by rib suppression.
Methodological Strengths
- Use of six distinct machine learning classifiers with chronological train/validation split
- Direct comparison of radiomics features before and after rib suppression with AUC-based evaluation
Limitations
- Retrospective single-dataset study with modest sample size (138 CXRs)
- No external validation or clinical outcome correlation reported
Future Directions: Prospective multi-center validation, integration with clinical variables and automated segmentation, and assessment of impact on clinical workflow and outcomes.
2. Human inborn errors of immunity underlying
In a retrospective review of 18 pediatric patients with inborn errors of immunity, common presentations included fever, cough, and hepatomegaly. Severe complications were frequent, notably septic shock, HLH, and ARDS, with diverse immunoglobulin and T-cell abnormalities, including cases of hyper-IgM syndrome.
Impact: Highlights the severe and heterogeneous complications of pediatric IEIs, including ARDS, informing clinicians about high-risk features and immunophenotypes.
Clinical Implications: Clinicians should anticipate severe complications such as ARDS, HLH, and septic shock in pediatric IEIs and consider early immunologic profiling (Ig levels and T-cell counts) and monitoring.
Key Findings
- Common symptoms: fever, cough, and hepatomegaly among pediatric IEI cases.
- Severe complications included septic shock, HLH, and ARDS.
- Immunologic abnormalities: pan-hypogammaglobulinemia (n=3), elevated IgM (n=3), elevated IgE (n=5), and decreased T lymphocyte counts (n=6).
- Four children were diagnosed with hyper-IgM syndrome.
Methodological Strengths
- Systematic retrospective characterization of pediatric IEI cases
- Detailed immunophenotyping across immunoglobulins and T-cell counts
Limitations
- Small sample size (18 patients) limits generalizability
- Retrospective design susceptible to selection and information biases
Future Directions: Prospective, multi-center cohorts with standardized immunophenotyping and outcome tracking to refine risk stratification for severe complications including ARDS.
3. An early onset Gitelman syndrome presenting in a boy with failure to thrive with recurrent hypokalemia and hypomagnesemia: a case report.
A 10-year-old boy with failure to thrive and recurrent hypokalemia/hypomagnesemia presented with respiratory distress during an acute infection. Genetic testing confirmed a pathogenic homozygous SLC12A3 mutation consistent with Gitelman syndrome; ICU care was required for life-threatening electrolyte derangements.
Impact: Highlights early-onset Gitelman syndrome with genetic confirmation and critical care needs, reinforcing diagnostic suspicion in children with persistent metabolic alkalosis.
Clinical Implications: Consider Gitelman syndrome in children with persistent metabolic alkalosis, hypokalemia, and hypomagnesemia; early genetic testing can guide management and prevent complications.
Key Findings
- Respiratory distress during acute infection in a child with failure to thrive and electrolyte abnormalities.
- Life-threatening hypokalemia and hypomagnesemia with ECG changes necessitated ICU admission.
- Pathogenic homozygous SLC12A3 mutation confirmed Gitelman syndrome.
Methodological Strengths
- Genetic confirmation of diagnosis via SLC12A3 pathogenic homozygous variant
- Detailed clinical and biochemical characterization with ICU course
Limitations
- Single case limits generalizability
- Lacks long-term outcome data
Future Directions: Case aggregation to delineate early-onset phenotypes and genotype-phenotype correlations; development of management algorithms for severe electrolyte crises.
