Clinical Report: Characteristics of Spontaneous Pneumomediastinum in Children

Overview

This study characterizes the clinical features of spontaneous pneumomediastinum (SPM) in pediatric patients and investigates its association with meteorological factors.

Background

Spontaneous pneumomediastinum (SPM) is a rare condition in children characterized by the presence of free air in the mediastinum without a preceding trigger. Understanding its clinical and epidemiological features is crucial for timely diagnosis and management.

Data Highlights

CharacteristicValue
Total Cases39
Male Cases34 (87.2%)
Median Age at Onset15.0 years
Common ComplaintChest Pain (59.0%)
Adjusted Odds Ratio for Temperature1.022

Key Findings

  • SPM cases predominantly occurred in adolescent boys with a median age of 15.0 years.
  • Chest pain was the most common presenting symptom, reported in 59.0% of cases.
  • A potential association was found between SPM onset and monthly average ambient temperature (p < 0.001).
  • The median body mass index of affected boys was 19.0 kg/m2.
  • One case of recurrence was noted among the 39 identified cases.

Clinical Implications

Clinicians should consider SPM as a differential diagnosis in cases of chest pain.

Conclusion

The study provides insights into the characteristics of pediatric SPM.
