Coughing up clues: 16-year-old girl with acute haemoptysis
Bibliographic record
Abstract
A 16-year-old previously well girl presented with bilateral painful lower leg swelling and non-pruritic blanching rash across her torso and upper and lower limbs. These symptoms started after commencing amoxicillin for presumed tonsillitis. She was diagnosed with serum sickness-like illness and started on non-steroidal agents. The rash and painful leg swelling improved over the next 48 hours. However, she subsequently developed fevers, cough and new-onset haemoptysis.She continued to deteriorate with increasing amounts of haemoptysis, work of breathing and escalating respiratory support requirements. Serial chest radiographs showed worsening lung consolidation and enlarging pleural effusion. A CT chest revealed extensive bilateral lung consolidation, most likely pulmonary haemorrhage. Subsequent investigations showed positive classic antineutrophil cytoplasmic antibody, confirming the diagnosis of granulomatosis with polyangiitis.

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.
