Pincer Nail Deformity Associated with Systemic Lupus Erythematosus
Bibliographic record
Abstract
Background: Systemic lupus erythematosus (SLE) is an autoimmune disorder with various systemic and cutaneous manifestations. Nail abnormalities, including onycholysis, red lunulae, pitting, and ridging, have been seen in patients with the disorder. To our knowledge, however, pincer nail deformity has yet to be reported coincident with the onset of SLE. Objective: We report a case of pincer nail deformity subsequent to the development of SLE and describe surgical treatment of the deformed nails. This is followed by a review of the literature. Conclusion: Acquired pincer nail is a dystrophy with numerous reported causative associations, including psoriasis, tumors of the nail apparatus, tinea ungium, ß-blocker usage, and now SLE. Pain from the resulting constriction can interfere greatly with daily activities and can be debilitating to the extent of requiring therapy.

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.
