Vasculitis Leading to Gangrene: An Early Presentation in a Rheumatoid Arthritis Patient
Bibliographic record
Abstract
Vasculitis is a late complication in rheumatoid arthritis (RA) and is seen in RA patients with long-standing disease. Rheumatoid vasculitis affects small-to-medium-sized vessels. In a few patients, vasculitis develops early in the course of the disease. Here, we report the case of a 32-year-old female who presented with gangrene in the second and third digits of the right foot and gangrene in the second digit of the left foot. She was on hydroxychloroquine and methotrexate for one year since the diagnosis of RA. The patient then developed Raynaud's phenomenon and blackish discoloration of toes. She was started on pulse methylprednisolone, aspirin, nifedipine, and pentoxifylline. As no improvement was seen, intravenous cyclophosphamide was started. There was no improvement even after starting cyclophosphamide, and the gangrene further worsened. Eventually, after consulting the surgical team, it was decided to amputate the digits. The second digits in both feet were subsequently amputated. Hence, a physician should always be careful in checking for signs of vasculitis in RA patients early in the course of the disease as well.

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.
