An Adolescent with a Progressive Movement Disorder
Bibliographic record
Abstract
Diagnosis: Sydenham chorea. The diagnosis of Sydenham chorea was suggested by the insidious development of choreic movements following an upper respiratory tract infection (figure 1; see also video 1, available in the electronic edition of Clinical Infectious DiseasesRecurrent arthralgia and the documentation of valvular regurgitation further supported a rheumatologic etiology. Culture of a throat swab yielded group A streptococci (GAS) with M protein type 5, a strain that has been identified as an etiologic agent in cases of acute rheumatic fever (ARF) [1]. Evidence of a recent GAS infection was confirmed by an elevated antistreptolysin O (ASO) titer of 1:795 (normal titer, <1:166). The hallmark characteristics of this manifestation of ARF are choreic movements, emotional lability, and hypotonia that may compromise the ability to sit or stand, as observed of our patient. Chorea often initially presents asymmetrically but typically progresses to bilateral involvement. Motor impersistence of the tongue and hands may limit independent feeding as well as hand use.

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.
