Nickel-Induced Systemic Contact Dermatitis and Intratubal Implants: The Baboon Syndrome Revisited
Bibliographic record
Abstract
Permanent sterilization using intratubal implants is becoming increasingly popular worldwide. We report the first case of a 40-year-old woman presenting a systemic contact dermatitis due to nickel-containing intratubal implants: the Essure system. The diagnosis was confirmed with positive patch test result for nickel and total clearance of dermatitis after removing the implants that contain a metallic spiral of nitinol (alloy of 55% nickel and 45% titanium). Systemic contact dermatitis to the intratubal implants could be explained by the corrosion of nitinol after implantation resulting in the release of nickel. In the literature, no similar case has been reported despite the introduction of intratubal implants since 2002. Dermatologists and gynecologists need to be aware of this type of complication. In practice, a thorough assessment for possible nickel contact dermatitis in a woman undergoing sterilization with Essure is recommended. Preoperative patch testing must be carried out if there is any doubt.

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.
