Pregnancy and lactation are times of physiologic stress during which bone turnover is accelerated. Previous studies have demonstrated that there is increased mobilization of lead from the maternal skeleton at this time and that calcium supplementation may have a protective effect. Ten immigrants to Australia were provided with either calcium carbonate or a(More)
There has been renewed interest in impacts on physiologic systems in the middle and older age groups, especially from fractures and hypertension. Increased blood lead (BPb) levels in postmenopausal females, which are thought to arise from bone demineralization, may also relate to other health effects including hypertension. Taking advantage of natural(More)
We compared high-precision lead isotopic ratios in deciduous teeth and environmental samples to evaluate sources of lead in 10 children from six houses in a primary zinc-lead smelter community at North Lake Macquarie, New South Wales, Australia. Teeth were sectioned to allow identification of lead exposure in utero and in early childhood. Blood lead levels(More)
We conducted a case-control study to determine the contribution of lead to blood from consumption of calcium supplements approximating the recommended daily intakes over a 6-month period. Subjects were males and females ages 21 to 47 years (geometric mean 32 years) with a geometric mean blood lead concentration of 2.5 microg/dL. They were subdivided into(More)
In the absence of any clearly identifiable pathologic condition, the prosthodontic patient demonstrating speech problems after insertion of complete dentures is having difficulty with loss of turbulence, because of the diminution of tactile location skills in speaking, or both. Potential aids to speech improvement are a nonanatomic papilla placed on the(More)
