Diffuse alveolar haemorrhage and pneumomediastinum after hypoglycaemic seizure
Bibliographic record
Abstract
Diffuse alveolar haemorrhage is a potentially life threatening condition. Given the multitude of possible etiologies and the infrequency with which it is encountered, diffuse alveolar haemorrhage poses a formidable diagnostic challenge. A 29 year old insulin-dependent diabetic man presented to the local emergency department with a 3 hour history of frank haemoptysis after a nocturnal hypoglycaemic seizure. Chest x-ray showed mid-lung predominant bilateral airspace disease. Computed tomography of the chest demonstrated pneumomediastinum and bilateral patchy ground glass opacities in a bronchovascular distribution. Bronchoalveolar lavage of the lingula returned consistently bloody returns with haemosiderin-laden macrophages. Work-up for secondary causes of diffuse alveolar haemorrhage including infection, vasculitides and connective tissue disease were negative and the haemoptysis resolved without any immunosuppressive therapy within 24 hours. Follow-up chest x-ray demonstrated marked interval improvement in the bilateral airspace disease. Previous reports have described post-ictal neurogenic pulmonary oedema but ours is the first description of seizure-induced alveolar haemorrhage with pneumomediastinum. This suggests that this condition may result from high intrathoracic pressures during a seizure leading to barotrauma and subsequent alveolar haemorrhage.

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; both teacher heads agree on what is shown here.
