Abstract
Parthenium hysterophorus and Tanacetum parthenium, members of the Compositae family, are important causes of allergic contact dermatitis due to plants. Parthenium dermatitis is a major problem in India and Australia. Parthenium hysterophorus causes a spectrum of clinical patterns. Parthenium dermatitis, in its classical form known as airborne contact dermatitis, primarily affects the exposed areas and the flexures. Other clinical patterns are a seborrheic pattern, widespread dermatitis, and exfoliative dermatitis. The trend of the clinical pattern is changing. The classic airborne contact dermatitis may change to photodermatitis resembling chronic actinic dermatitis or mixed pattern dermatitis. The allergens responsible for contact dermatitis are sesquiterpene lactones and are present in the oleoresin fraction of the leaf, the stem, and the flower and also in pollen. The allergens can be extracted in various solvents (such as acetone, alcohol, ether, and water) and then used for patch testing. Acetone extract of Parthenium is better than aqueous extract in eliciting contact sensitivity. Treatment of Parthenium dermatitis is mostly symptomatic. Topical steroids, antihistamines, and avoidance of Parthenium are the mainstay of treatment for localized dermatitis. Systemic corticosteroids and azathioprine are frequently needed for severe or persistent dermatitis.

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.
