Drug-induced esophageal injuries with an atypical presentation mimicking acute coronary syndrome
Bibliographic record
Abstract
BACKGROUND: Pill-induced esophageal injury may cause severe complications if not diagnosed in a timely fashion. The condition is under-recognized and under-reported, and some patients present with atypical clinical or endoscopic features mimicking other common conditions. If the diagnosis is missed the patient will continue to take the offending drug, potentially worsening the illness. We present a case in which acute coronary syndrome was the initial working diagnosis leading to a delay in diagnosis of doxycycline-induced esophageal injury. The patient developed multiple esophageal ulcers and hemorrhage. CASE PRESENTATION: A 50-year-old male driver with a history of hypertension and dyslipidemia was brought to the emergency department with complaints of severe retrosternal chest pain, vomiting, diaphoresis and syncope. On initial evaluation, acute coronary syndrome was considered due to the clinical presentation and history of cardiovascular risk factors. Electrocardiogram and serum troponins were normal. On the second day of his admission, the patient developed odynophagia and bloody vomitus. Esophagogastroduodenoscopy revealed extensive esophageal ulcerations with hemorrhage. The patient was taking Doxycycline capsules for an acute febrile illness. Doxycycline is the oral medication most commonly reported to cause esophageal injury. Doxycycline was discontinued, and the patient was treated with intravenous omeprazole and oral antacid suspension. The patient improved, was discharged after 6 days of hospitalization, and reported resolution of all symptoms at an outpatient follow-up visit 3 weeks later. CONCLUSION: Medication-induced esophageal injury can present with atypical symptoms mimicking acute coronary syndrome. This condition should be included in the initial differential diagnosis of patients presenting with acute chest pain, especially those taking oral medications known to cause esophageal injury.

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; a candidate call from one teacher head, not a consensus.
