Abstract

fetched live from OpenAlex

Erythema elevatum diutinum is a distinct and rare form of chronic, recurrent leukocytoclastic vasculitis that typically presents with firm, smooth erythematous to violaceous papules or nodules symmetrically distributed over the extensor surfaces. Herein, we report an unusual case of erythema elevatum diutinum in a 32-year-old female who presented with a several-year history of chronic recurrent palpable purpura prior to the development of classic nodular lesions. This presentation facilitated a timely diagnosis and highlighted the histopathologic progression of the disease broadening the clinical spectrum of erythema elevatum diutinum.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
