EFFECT OF ANTITHYROID TREATMENT ON CALCIUM-PHOSPHORUS METABOLISM IN HYPERTHYROIDISM
Abstract
Histomorphometric analysis of iliac crest biopsies was performed after tetracycline double-labelling in 22 hyperthyroid patients before and after medical antithyroid treatment for an average period of 4 months. The initially increased cortical porosity was normalized during treatment whereas the amount of trabecular bone was unchanged. The osteoclastic resorption in cortical bone decreased but was still elevated. The osteocytic osteolysis remained slightly increased. In trabecular bone, however, the bone turn-over decreased to a subnormal level following treatment and the surfaces were inactive in bone resorption and bone formation. An increase was observed in the amount, extent and width of osteoid seams due to an increase in the lifespan of bone forming sites and a prolongation of the maturity period of osteoid. The observed increased deposition of cortical bone after antithyroid treatment may explain the positive calcium balance in this period.

Hyperthyroidism causes high bone turnover with increased frequency of initiation of bone remodelling sites together with increased bone resorption and formation rates.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
