Trichopliyton violaceum Infection in Three Black Brothers
Bibliographic record
Abstract
Case 1 was a 3-year-old with tinea capitis, while Case 2 was a 5-year-old with kerion celsi. These conditions developed between December 1997 and January 1998 when the patients were living in Canada. Case 3 was a 7-year-old who developed kerion celsi in March 1998 in Japan. For Cases 1 and 2, the referring doctor had detected a fungal infection a few weeks previously, and griseofulvin was administered orally to Case 1 for three weeks and Case 2 for one week prior to consultation at our department. Both Cases 1 and 2 visited our department initially on May 7, 1998 with the causative agent separated from their lesions by the referring doctor respectively. The causative agent was identified as Trycophyton violaceum by our department. KOH-prepared direct microscopy and culture were positive for Case 1, but negative for Case 2. Infected hairs of Case 1 showed a chain of large arthrospores arranged in parallel rows inside the hair. Case 3 visited our department initially on May 21, and T. violaceum was also isolated from this patient's lesion. A reddish purple isolate that was stored for five months after isolation and culture was subcultured using a Sabouraud agar containing thiamin. After two months, brown colonies without red pigment were seen in the reddish purple colonies. Slide culture performed for both colonies showed intercalary and terminal chlamydospores, thus confirming that they were the same fungus. These findings appear to represent the conversion of T. violaceum into T. glabrum.

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.
