CHRONIC CARBON MONOXIDE POISONING PRESENTING AS NEW DAILY PERSISTENT HEADACHE: A CASE REPORT AND REVIEW OF THE LITERATURE
Bibliographic record
Abstract
Objectives: To sensitize the paediatric neurology community to the presentation of chronic carbon monoxide poisoning. Methods: A case report demonstrating the clinical presentation of chronic CO poisoning, a review of the literature and indications for treatment with hyperbaric oxygen therapy (HBO) in the paediatric population. Results: A 15 year old girl presented with a history a sudden onset persistent headache for 4 weeks associated with dizziness, fatigue, sleeplessness, auditory and visual hallucinations and abdominal pain. She complained of concentration and memory difficulties. She had an unremarkable physical and neurological examination. MRI, EEG were normal but investigation found an elevated carboxyhemoglobin level. Assessment of the household was positive for a gas leak of unknown duration, with direct exposure to the individual. Neuropsychological evaluation was performed followed by treatment with hyperbaric oxygen therapy. The results are discussed. Conclusion: Chronic low-dose carbon monoxide (CO) exposure can present insidiously with symptoms that are frequently neuropsychiatric in nature. In adults, chronic CO poisoning is often misdiagnosed for flu like or psychological illnesses. The current literature is reviewed. Some studies have shown the use of neuropsychological evaluation to demonstrate the effect of a toxic exposure. The efficacy of treatment with hyperbaric oxygen therapy is controversial and is discussed. A high level of clinical suspicion is needed to make the diagnosis.

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.
