Rapid Increase in Grip Force After Start of Pamidronate Therapy in Children and Adolescents With Severe Osteogenesis Imperfecta
Bibliographic record
Abstract
OBJECTIVE: To examine changes in grip force during pamidronate therapy in children and adolescents with severe osteogenesis imperfecta (OI). METHODS: Maximal isometric grip force of the nondominant hand was prospectively determined in 42 patients (age at the start of the study: 7.3-15.9 years; 18 girls) with severe forms of OI. Patients were treated with intravenous pamidronate infusions given in 4 monthly cycles, each cycle consisting of 3 infusions (1 mg pamidronate/kg body wt) on 3 successive days. RESULTS: At the start of pamidronate therapy, grip force was low compared with age-specific reference data (age z score mean +/- standard deviation: -2.7 +/- 2.1) but was normal for weight (weight z score: -0.1 +/- 1.8). Four months after the first pamidronate infusion cycle, grip force had increased significantly, whether related to age (age z score: -2.0 +/- 1.8) or to weight (weight z score: 0.6 +/- 1.5). At 2 years after the start of therapy, grip force z scores were not significantly different from the 4-month results. CONCLUSIONS: Maximal isometric grip force markedly increases after a single cycle of intravenous pamidronate in children with severe forms of OI, and this gain in grip force is maintained for at least 2 years.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
