Case report: An unusual case of ‘black’ larynx
Bibliographic record
Abstract
Ulcerative necrotic supraglottitis is a rare entity of laryngeal infection leading rapidly in laryngeal necrosis, systematic complications and potentially fatal outcomes. We present a case of a 50-year-old gentleman with ulcerative necrotising supraglottitis and no co-morbidities who presented in Ear Nose and Throat Service in the Accident and Emergency department due to dysphagia and weakness. He was treated with an emergency tracheostomy with neck exploration and washout and received appropriate supporting antibiotic regime. He improved and was eventually decannulated, able to breathe phonate and swallow appropriately. After a thorough review of the literature regarding necrotising infections of the laryngeal cavity, only 7 cases have been reported, all in immunocompromised patients with severe complications. Our case report is the first ulcerative necrotic supraglottitis in a healthy individual who was treated early and aggressively with impressive results.

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.
