Medical image of the week: Kartagener syndrome
Bibliographic record
Abstract
No abstract available. Article truncated at 150 words. A 65-year-old woman presented with 7 days of productive cough and the new onset sharp central chest pain. She has a known history of chronic sinusitis and COPD after being a 50 pack-year smoker. On examination, her blood pressure was 116/70 with a heart rate of 86 (sinus rhythm) and oxygen saturations were 93% on 4L/min by nasal cannula. She had bilateral expiratory wheezes with reduced air entry on the left side. An AP chest x-ray revealed dextrocardia with a left sided tension pneumothorax (Figure 1A). Our patient was stabilized with an urgent chest tube insertion and taken for a CT chest and abdomen. CT chest indicated diffuse bronchiectasis (Figure 1B, arrow) with a CT of the abdomen showing reversal of major abdominal organs (Figure 1C). First described in 1933, the triad of chronic sinusitis, bronchiectasis, and situs inversus is classic for Kartagener syndrome (1). Otherwise known as primary ciliary ...

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
