The Value of Different Radiological Modalities in Assessment of Spontaneous Pneumomediastinum: Case Review and Diagnostic Perspective
Bibliographic record
Abstract
Pneumomediastinum (PM), or a mediastinal air leak, is a known morbidity in neonates. Among predisposing factors, the most significant are mixed lung diseases, such as pneumonia or meconium aspiration syndrome, with coexisting atelectasis and airway obstruction. We report an unusual presentation of significant spontaneous pneumomediastinum in a term newborn delivered by elective cesarean section with no history of active resuscitation at birth. Timely diagnosis of SPM is important for both management and prognosis. We believe that lung ultrasound (LUS) is a promising screening tool for early detection of PM in neonates, and could help avoid unnecessary exposure to radiation in delicate neonates. More simultaneous studies comparing chest X-ray (CXR), LUS, and computed tomography (CT) scans may help to prove the utility value of point-of-care ultrasounds as a primary diagnostic tool in identifying this morbidity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
