Longitudinal changes in bone density in hyperparathyroidism.
Primary hyperparathyroidism (HPTH) is a known risk factor for cortical bone loss. The primary objective of this study was to examine the time course and location of changes in bone mass within the first year after parathyroidectomy (PAX). The secondary goal was to evaluate the efficacy of combined estrogen therapy and parathyroidectomy in postmenopausal women. Thirty-two subjects with primary H...
متن کاملImpact of bone lead and bone resorption on plasma and whole blood lead levels during pregnancy.
The authors tested the hypotheses that maternal bone lead burden is associated with increasing maternal whole blood and plasma lead levels over the course of pregnancy and that this association is modified by rates of maternal bone resorption. A total of 193 Mexican women were evaluated (1997-1999) in the first, second, and third trimesters of pregnancy. Whole blood lead and plasma lead levels ...
متن کاملBone lead levels in adjudicated delinquents. A case control study.
BACKGROUND Lead exposure shares many risk factors with delinquent behavior, and bone lead levels are related to self-reports of delinquent acts. No data exist as to whether lead exposure is higher in arrested delinquents. The goal of this study is to evaluate the association between lead exposure, as reflected in bone lead levels, and adjudicated delinquency. METHODS This is a case-control st...
متن کاملChanges in serial blood lead levels during pregnancy.
The first step in modeling lead kinetics during pregnancy includes a description of sequential maternal blood lead (PbB) during pregnancy and the factors controlling it. We analyzed PbB of 105 women living in the Valley of Mexico from week 12 to week 36 of pregnancy and again at parturition. We also used data from all women contributing blood at any stage of pregnancy to determine antecedents o...
متن کاملThe influence of bone and blood lead on plasma lead levels in environmentally exposed adults.
There is concern that previously accumulated bone lead stores may constitute an internal source of exposure, particularly during periods of increased bone mineral loss (e.g., pregnancy, lactation, and menopause). Furthermore, the contribution of lead mobilized from bone to plasma may not be adequately reflected by whole-blood lead levels. This possibility is especially alarming because plasma i...
