Orthopaedic manifestations of Brachmann???de Lange syndrome: a report of 34 patients
Bibliographic record
Abstract
Brachmann-de Lange syndrome (BDLS) is a disorder of unknown cause that is recognized on the basis of characteristic facies in association with growth retardation, mental retardation and, in many cases, upper limb anomalies. Because of its association with skeletal anomalies, patients with the syndrome are often referred to the paediatric orthopaedic surgeon. Thirty-four patients with Brachmann-de Lange syndrome were evaluated for the prevalence and pattern of musculoskeletal involvement. The average age of the patients was 10.2 years (range, 1 month to 44 years). Both sexes were affected equally. The common orthopaedic manifestation affected the hand (100%), elbow (47%), and the heel cord (26%). Severe bony anomalies included complete absence of the hand in one case, and ulna hemimelia in two cases. In two patients bilateral Legg-Perthes-like changes were noted. Scoliosis presented in four cases, all before the age of 10 years. Surgery was performed in two patients with severe bilateral equinovarus feet. Despite the constellation of musculoskeletal findings, most of the patients did not have surgical intervention for their deformities.

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.
