Diagnostic and therapeutic challenges of cutaneous leishmaniasis in Canada: A case report
Bibliographic record
Abstract
Cutaneous leishmaniasis is increasingly reported in non-endemic areas due to international travel. This case describes a 17-year-old male from Western Canada who developed localized cutaneous leishmaniasis ( Leishmania mexicana ) after visiting the Yucatán Peninsula, Mexico. His persistent skin ulcers initially failed to respond to supportive wound care, thermotherapy, and systemic antimicrobials. Skin biopsy revealed granulomatous inflammation, and polymerase chain reaction confirmed L. mexicana species. Limited access to first-line treatments (e.g. miltefosine) in Canada complicated management. While intravenous liposomal amphotericin B provided partial improvement, complete healing occurred only after obtaining miltefosine. This case highlights the challenges of diagnosing and treating cutaneous leishmaniasis in non-endemic regions.

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.
