Toxic epidermal necrosis associated with phenobarbitone: a case report and brief review of the literatures
Bibliographic record
Abstract
BACKGROUND: Toxic epidermal necrolysis (TEN)/Stevens-Johnson syndrome (SJS) is the spectrum of severe, acute, mucocutaneous, T-cell mediated delayed type IV hypersensitivity reaction and universally related to different drugs. Phenobarbitone is known to cause hypersensitivity reactions with benign pattern; ranging from a mild to moderate rashes but not life-threatening reactions such as TEN/SJS. CASE REPORT: We report a 14-year-old asthmatic male patient admitted to a local hospital for an acute exacerbation of asthma, after he presented with shortness of breath, cough, and fever. He was treated with bronchodilator and antibiotics. On subsequent days, the patient developed new onset generalized tonic clonic seizure in the hospital for which he was started on phenobarbitone of 100 mg twice daily. Two weeks after initiation of phenobarbitone, the patient developed extensive blistering skin eruptions; which subsequently exfoliated unevenly. Associated with the hypersensitivity skin reaction, the patient reported low grade fever, sore throat, and dysphagia. The exfoliation also involved oral and conjunctival mucosa; with estimated 65% body surface area involvement. The laboratory investigations were relevant for mild leucocytosis, prolonged prothrombin time, and reduced albumin. Phenobarbitone was discontinued and replaced with clonazepam; and the patient was managed with fluids replacement, IV antibiotics, twice daily wound care, analgesics, and naso gastric tube feeding. On subsequent days the patients' clinical condition started improving; the skin lesion also started to heal and exfoliate in most of the affected skin surface areas, and the patient was discharged improved after ten days of intensive care unit. CONCLUSION: In summary, the present case describes, a 14-years-old young child with history of asthma and seizure disorder; and developed toxic epidermal necrosis following exposure to Phenobarbitone. This case also highlighted the better prognosis observed in pediatric population with TEN.

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.
