An elusive cause of hypoxaemia in a paediatric patient
Bibliographic record
Abstract
A 5-year-old girl presented to an ambulatory cardiology clinic with shortness of breath, described by the patient's mother and chest discomfort on exertion. At this visit, she was noted to have low baseline room air oxygen saturations of 89%. Subsequent cardiac, respiratory and haematological investigations including contrast echocardiography, CT scan of the chest, polysomnography and haemoglobin electrophoresis were unhelpful in yielding a diagnosis. A CT scan of the chest with contrast was performed which revealed a persistent left-sided superior vena cava that appeared to be draining into the left atrium, creating a right-to-left shunt. This was not revealed on contrast echocardiography as contrast (micro bubbles) had been injected into the right arm. This case report highlights the nuances of diagnostic investigations, which without a high index of suspicion may exclude a timely diagnosis and therapeutic intervention.

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.
