Maternal and Fetal Outcome After Long-Term Pamidronate Treatment Before Conception: A Report of Two Cases
Bibliographic record
Abstract
The pregnancies of two women with osteogenesis imperfecta who received intravenous pamidronate before conception are reported. The mothers suffered no ill effects. One baby had transient asymptomatic hypocalcemia and one had bilateral talipes equinovarus. This report documents the pregnancy outcomes of two women with osteogenesis imperfecta (OI), types I and IV, who received intravenous pamidronate as part of an observational trial before conception. Pamidronate was not administered after conception. Other than hyperemesis in one woman, the pregnancies and deliveries were uneventful. Both babies inherited OI from their mothers. The baby with OI type IV also had bilateral talipes equinovarus. Biochemical evaluation of the mothers and babies at 24 h and/or 2 weeks postpartum was normal, apart from one baby with asymptomatic hypocalcemia at 24 h of age that had resolved when next measured on day 11 of life. No biochemistry was available on the second child until 13 days of age. Neither baby had skeletal modeling abnormalities consistent with in utero pamidronate exposure. The lumbar spine (L1-L4) areal BMD and anterior to posterior height ratios of lumbar vertebral bodies of both women remained constant during pregnancy. Both the mothers and babies remain well and free of fracture 14 and 16 months postpartum.

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.
