Natural History of Oppenheim's Dystonia (DYT1) in Israel
Bibliographic record
Abstract
The question of whether a fetus carrying the GAG deletion on the DYT1 gene responsible for Oppenheim's dystonia should be aborted is frequently raised. The objective of this study was to characterize the clinical spectrum and natural course of Oppenheim's dystonia in Israel. Thirty-three patients (19 male) with genetically confirmed Oppenheim's dystonia were evaluated. The Dystonia Rating Scale (maximum score 120) and the Disability Scale (maximum score 30) were used to score severity at the last visit. After a mean of 15.5 +/- 13.8 years of symptoms, the mean Dystonia Rating Scale and Disability Scale scores were 22.7 +/- 14.7 and 7.7 +/- 4.3, respectively. Twenty-one patients (63.6%) have progressed into generalized dystonia. Five patients (15%) are wheelchair bound and three (9%) are using walking aids. All patients have normal cognitive function. Baclofen, trihexyphenidyl, and botulinum toxin were the drugs used. Nine patients (one patient had both) underwent neurosurgical intervention: thalamotomy for six (two bilateral) and pallidotomy for four (three bilateral). The bilateral pallidotomy provided only short-term benefit. The modern treatments combining drugs, botulinum toxin, and functional neurosurgery allow most patients with Oppenheim's dystonia to have independence and a relatively good quality of life.

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.
