Abstract

fetched live from OpenAlex

Nailfold capillaroscopy is well established in systemic sclerosis; however, abnormalities (scleroderma or scleroderma-like patterns) are identified in other connective tissue diseases, such as myositis, even in the absence of Raynaud's phenomenon. Although this may be known within the rheumatology world, myositis cases often present to other subspecialists who may be unfamiliar with the value of capillaroscopy. We present four cases of myositis that initially presented to non-rheumatology subspecialists where capillaroscopy played a role in confirming the diagnosis. Nailfold capillaroscopy is especially useful in cases of isolated interstitial lung disease, atypical and isolated rashes, and to delineate between myositis mimickers, whether pathologic or clinical. It is a noninvasive tool, which is useful early in the work-up of myositis to identify features consistent with a connective tissue disease.

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.
