Form fruste pachydermoperiostosis associated with ptosis and floppy eyelid syndrome
Bibliographic record
Abstract
Pachydermoperiostosis (PDP), also known as idiopathic or primary hypertrophic osteoarthropathy or Touraine-Solente-Gole Syndrome, is a rare genetic disorder affecting skin and bone, consisting of pachydermia and periostosis. Pachydermia is a thickening and furrowing of the skin and face in a manner that resembles the skin of a pachyderm. Periostosis is periosteal new bone formation in the long bones. In this report, a 16-year-old boy presented with bilateral ptosis and floppy eyelids. He was successfully treated with bilateral upper eyelid pentagonal wedge resections. Histopathology of the excised tissue demonstrated mild epidermal acanthosis and marked increased dermal collagen with thickening of individual fibers, consistent with pachydermia, as well as papillary conjunctival inflammation and Meibomian glands hyperplasia with ductal dilatation, consistent with floppy eyelid syndrome. Radiographic imaging did not demonstrate any signs of periostosis, confirming the diagnosis of form fruste PDP. In a diligent search of the peer-reviewed medical literature (using PubMed and cross-referenced literature), this case may be the first report of floppy eyelid syndrome and ptosis associated with form fruste PDP.

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.
