Successful follicular unit extraction in a case of inactive, recalcitrant alopecia barbae
Bibliographic record
Abstract
Alopecia areata (AA) is a non-scarring autoimmune type of alopecia. Hair transplantation in AA is not practiced as the implanted follicular grafts might be destroyed due to underlying autoimmune pathology. A biopsy proven 28 year old male patient of AA presented to us with an 8-year history of a hairless patch over the beard area. He underwent many treatments by other dermatologist with oral, topical, and intralesional immunosuppressants, which curtailed his disease progression but failed to re-grow hair. Biopsy during his visit revealed absence of inflammatory infiltrates and empty hair tracts replaced by fibrotic tracts. Follicular unit extraction (FUE) was done successfully after counseling the patient about the controversial role of hair transplant surgery in AA. Hair growth was achieved within 6 months with no recurrence during 1-year follow up. FUE can be opted for long-standing and clinically stable cases of AA; histopathology and dermoscopy being the guiding lights in determining the disease inactivity.

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.
