Abstract
INTRODUCTION: Osteogenesis imperfecta (OI) is a heritable disorder characterized by bone fragility and reduced bone mass. It may present with a wide range of severity. About 85% of the cases are linked to mutations in one of the two genes encoding type I collagen. In other cases of OI, there are mutations in the expression of a cartilage-related protein or of 3-prolyl-hydroxylase. Increased bone turnover rate, due to the repair activity triggered to replace weak tissue, is the rule. Often, disuse bone loss further compounds the decrease in bone mass. These findings justify the use of bisphosphonates to reduce osteoclast-mediated bone resorption, and so tilt the remodeling balance towards an increase in bone mass. CONCLUSIONS: Cyclical intravenous pamidronate administration reduces bone pain, and increases bone mass and density. No negative effects on growth or fracture repair have been observed. There is an increase in size of vertebral bodies and thickening of cortical bone, which translates into decreased fracture incidence and improved ambulation. However, the long-term consequences of low bone turnover in children with OI are unknown at the present time. Innovative surgery and specific occupational and physiotherapy programs are integral parts of the treatment protocol. This approach will prevail until gene-based therapies become clinically applicable.

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.
