Characterization of Non-Food Foreign Bodies Aspirated by Children: A Systematic Review of the Literature.

BACKGROUND: Foreign Body Aspiration (FBA) represents a leading cause of death among unintentional injuries in children less than one year of age. This study reviewed case reports and case series reporting non-food FBA in children to characterize aspirated foreign bodies, describing the clinical presentations and the outcomes. METHODS: A systematic review was conducted according to the PRISMA checklist. Case reports and case series presenting non-food FBA in children (up to 18 years) were eligible to be included. Information regarding study characteristics, child demographics, foreign body characteristics, clinical presentation, and outcome were extracted. RESULTS: The review included 248 articles published between 1965 and 2023, corresponding to 294 cases. The male gender was the most prevalent (194 cases, 66%), and the median age was 3.5 years (Interquartile Range: 1-8 years). Button batteries were the objects most frequently reported (21 cases, 7.1%). Objects were located most often in the bronchus (102 cases, 35%). The most common symptom was cough (181 cases, 62%), followed by respiratory distress (160 cases, 54%) and wheezing/stridor (127 cases, 43%). CONCLUSIONS: The present systematic review may have relevant public health implications, since characterizing objects that cause foreign body injuries is essential to reduce the burden of this phenomenon.

Early-life exposure to antibiotics and subsequent development of atopic dermatitis.

BACKGROUND: Antibiotic exposure may be associated with atopic dermatitis (AD). We assessed the risk of developing AD among children early exposed to antibiotics. RESEARCH DESIGN AND METHODS: From the Italian Pedianet database, children aged 0-14 years between 2004-2017 were enrolled from birth up to at least one year. Cox proportional-hazards models were fitted to estimate Hazard Ratios (HR) and 95% Confidence Intervals (CI) for the association between antibiotic exposure during the first year of life with incident AD. Exposure was also considered as a time-varying variable. RESULTS: 73,816 children were included in the final cohort, of which 34,202 had at least one antibiotic prescription. Incident AD was present in 8% of unexposed and exposed children. Early antibiotic exposure was not associated with any excess risk of AD compared to unexposed children (HR: 1.02, 95% CI: 0.97-1.07), and no dose-response effect was observed. In the time-varying analysis, antibiotic exposure was significantly associated with AD onset (1.12, 1.07-1.17). However, when taking into account the time-lag between exposure and outcome, risks progressively decreased, suggesting possible protopathic bias. CONCLUSION: These results are not suggestive of any significant association between exposure to antibiotics and subsequent AD onset and support the possible presence of protopathic bias.
