Allergic Contact Dermatitis from Chlorhexidine
Bibliographic record
Abstract
Although chlorhexidine is a widely used substance, allergic contact dermatitis from chlorhexidine has rarely been reported. Our objective was to study all cases of allergic contact dermatitis from chlorhexidine that were seen at St John's Institute of Dermatology from January 1983 to June 2002. The case records of all patients with positive patch-test reactions to chlorhexidine during the study period were retrieved. The clinical presentation, strength, and relevance of the positive patch-test results as well as possible sources of exposure were studied. There were five cases of allergic contact dermatitis from chlorhexidine during the study period; three of these patients had positive patch-test reactions to chlorhexidine that were of current relevance. The possible sources of exposure included Hibisol, Hibiscrub, a chlorhexidine spray, and peri- and postoperative antiseptic solutions. We concluded that allergic contact dermatitis from chlorhexidine is rare. However, when it occurs, it may cause a severe dermatitis reaction.

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; both teacher heads agree on what is shown here.
