Obliterative Portal Venopathy Caused by Oral Contraceptive Pills: A Case Report
Bibliographic record
Abstract
Oral contraceptive pills (OCPs) have a known prothrombotic effect. Obliterative portal venopathy (OPV) can be seen in patients with underlying hypercoagulability. We present a case of a 19-year-old female patient taking OCPs who presented with obstructive jaundice. Her main concern was pruritis. An extensive workup was done to reach a diagnosis but it came back negative. A liver biopsy showed OPV. This was thought secondary to her OCP use. Her OCPs were discontinued which resulted in a complete resolution of her symptoms and laboratory abnormalities. Cases with a direct relationship between OPV and OCP use are extremely rare. More studies are required to establish a correlation between OPV and OCPs. OPV should be considered in the differential diagnosis among patients with obstructive jaundice without an obvious cause, especially in patients taking OCPs. Treatment is stopping the OCPs with close follow-up to confirm disease resolution.

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.
