Oral contraceptive pill-induced esophagitis: a rare cause of pill esophagitis in a Rwandan woman
Bibliographic record
Abstract
We describe a case of oral contraceptive pill (OCP)-induced esophagitis in a 43-year-old Rwandan woman. She presented with epigastric and retrosternal pain and reported daily use of a combined OCP containing ethinyl estradiol and levonorgestrel. Upper endoscopy revealed a solitary, clean-based esophageal ulcer. Histopathologic evaluation excluded infectious causes, and she improved with proton pump inhibitor therapy and modification of pill consumption habits. This is the first reported case of OCP-induced esophagitis on the African continent and the fifth case overall, and it highlights the importance of awareness of this rare gastrointestinal adverse effect of a commonly used class of drugs, particularly in an area of the world that is promoting the increased uptake of female contraception as a tool for family planning.

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.
