Abstract

It has been suggested recently that, although fluoride therapy may decrease the occurrence of vertebral fractures, it could increase the risk of hip fractures. To evaluate this possibility, we combined retrospective data from five medical centers that have had a large experience with this therapeutic regimen. In 416 osteoporotic patients who were followed for more than 1,000 patient-years of fluoride treatment, there were 17 nontraumatic hip fractures. This incidence of 1.6% per year is similar to the incidence, 1.9% per year, for 120 of the patients in this series who had been followed prospectively for 3 years prior to initiation of fluoride therapy. The expected incidence for women of the same age in the general community is 0.5% per year. Thus, untreated osteoporotic women are at increased risk for hip fracture, but treatment with fluoride seems neither to decrease nor to increase the incidence of hip fracture substantially.

    We describe a case of development of painful periostitis deformans in a 39-year-old woman who was receiving long-term voriconazole treatment for Aspergillus infection as a complication of orthotopic liver transplant. Measurement of fluoride levels strongly supports fluorosis to be the mechanism of the voriconazole-induced periostitis deformans and supports the concept

    Acquired osteosclerosis is a rare disorder of bone formation but an important consideration in adults with sclerotic bones or elevated bone density results. In such patients, malignancy, hepatitis C, and fluorosis should all be considered when making a diagnosis. We describe 4 patients evaluated at our Metabolic Bone Disease Clinic

    A 72-year-old woman on chronic voriconazole therapy for recurrent histoplasmosis developed a painful forearm mass. Laboratory and imaging findings were consistent with a diffuse periostitis. Her symptoms resolved after discontinuation of voriconazole. To our knowledge, this is the first case of voriconazole-induced periostitis to be reported in a patient with

    Drug Levels and Effects No published experience exists with sulfur hexafluoride during breastfeeding. Because the half-life of the agent is about 10 minutes and absorption of the drug by the infant is unlikely. If sulfur hexafluoride is required by the mother, it is not a reason to discontinue breastfeeding.[1] Because of

  • Fluoride & Spontaneous Hip Fractures in Osteoporosis Patients

    Due to its ability to increase vertebral bone mass, fluoride has been used as an experimental treatment for osteoporosis (doses > 20 mg/day). Fluoride treatment, however, proved far more harmful than beneficial. Not only was fluoride therapy shown to increase fracture rates among the treated patients, it was also found to

  • In Vitro Studies on Fluoride & Bone Strength

    The "in vitro" research on fluoride and bone strength confirms what has repeatedly been found in animal and human studies: the more fluoride a bone has, the weaker the bone becomes. In an in vitro bone study, the researcher directly exposes a human or animal bone to a fluoride solution

  • The Relationship Between Fluoride, Bone Density, and Bone Strength

    Although fluoride has generally been found to reduce the bone density of cortical bone, it is well documented that fluoride can increase the density of trabecular bone (aka cancellous bone). Trabecular  bone is the primary bone of the spine, whereas cortical bone is the primary bone of the legs and arms. While increases in

    Current epidemiological evidence indicates that the margin of safety between the level of fluoride in water that does, and does not, increase the risk of fracture is insufficiently large to protect all members of society from fluoride-induced damage to bone.
