Abstract

fetched live from OpenAlex

Erdheim-Chester disease (ECD) is a rare non-Langerhans multisystemic histiocytosis. This disorder is characterized by CD68+/CDa1- foamy histiocytic infiltration of tissues, especially bones, retroperitoneum, heart, lung and brain. Clinical manifestations may range from asymptomatic bone lesions to multiorganic symptoms. Bone pain in lower extremities is the most common symptom. Typical imaging findings include symmetric diaphyseal osteosclerosis of long bones, periaortic sheathing (“coated aorta”) and retroperitoneal infiltration (“hairy kidney”). Lung and brain radiological abnormalities may also be seen. BRAF-V600E mutation is present in almost half of this population. Vemurafenib, a mutated BRAF inhibitor, is a promising treatment for patients with this mutation. We present the case of a 60-year-old man who arrived with a pathological right humerus fracture, initially thought to be tuberculous in nature. ECD was considered after imaging.

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.

Not 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.
