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.

Environmental Fluoride 1977 by Rose & Marier
The Associate Committee on Scientific Criteria for Environmental Quality was established by the National Research Council of Canada in response to a mandate provided by the Federal Government to develop scientific guidelines for defining the quality of the environment. The concern of the NRC Associate Committee is strictly with scientific

Environmental Toxicity Assessment of Sodium Fluoride and Platinum-Derived Drugs Co-Exposure on Aquatic Organisms.
Pharmaceuticals are widely acknowledged to be a threat to aquatic life. Over the last two decades, the steady use of biologically active chemicals for human health has been mirrored by a rise in the leaking of these chemicals into natural environments. The aim of this work was to detect the

Elevated fluoride levels and periostitis in pediatric hematopoietic stem cell transplant recipients receiving long-term voriconazole
Azole therapy is widely utilized in hematopoietic stem cell transplant (HCT) recipients for the treatment of aspergillus. Complications of voriconazole treatment related to its elevated fluoride content have been described in adults, including reports of symptomatic skeletal fluorosis. We review fluoride levels, clinical, and laboratory data in five pediatric HCT recipients

Correlation of pain and fluoride concentration in allogeneic hematopoietic stem cell transplant recipients on voriconazole
Supportive care guidelines recommend anti-mold prophylaxis in hematopoietic stem cell transplant (HSCT) recipients deemed high-risk for invasive fungal infection, leading to long-term use of voriconazole following allogeneic HSCT in patients that remain immunocompromised. Voriconazole has been associated with periostitis, exostoses, and fluoride excess in patients following solid organ transplant, HSCT

Non-Endemic Skeletal Fluorosis: Causes And Associated Secondary Hyperparathyroidism (Case Report and Literature Review).
Highlights Fluorocarbon “huffing” is an under-appreciated cause of skeletal fluorosis (SF) We present a SF case with hyperparathyroidism, osteosclerosis, and osteomalacia SF may go undetected due to variation in symptoms, radiology, and biochemistry Dietary calcium, prior bone health, and skeletal F exposure influence SF features SF is common in

Fluoride Reduces Bone Strength Prior to Onset of Skeletal Fluorosis
The majority of animal studies investigating fluoride's impact on bone strength have found that fluoride has either no effect, or a detrimental effect, on bone strength. Importantly, several of the animal studies that have found fluoride reductes bone strength have reported that this reduction in strength occurs before signs of skeletal fluorosis

Clinical Trials: Fluoride Treatment & Bone Fracture in Osteoporosis Patients
Due to its ability to increase bone mass, fluoride has been used as an experimental treatment for osteoporosis. The results, however, have generally been disastrous. Rather than prevent bone fractures in osteoporosis patients, fluoride therapy (at doses of 20-34 mg/day) was repeatedly found to increase fracture rates. One of the most

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

Mechanisms by which fluoride may reduce bone strength
Based on a large body of animal and human research, it is now known that fluoride ingestion can reduce bone strength and increase the rate of fracture. There are several plausible mechanisms by which fluoride can reduce bone strength. As discussed below, these mechanisms include: Reduction in Cortical Bone Density De-bonding of

Exposure Pathways Linked to Skeletal Fluorosis
Excessive fluoride exposure from any source -- and from all sources combined -- can cause skeletal fluorosis. Some exposure pathways , however, have been specifically identified as placing individuals at risk of skeletal fluorosis. These exposure pathways include: Fluoridated Water for Kidney Patients Excessive Tea Consumption High-Fluoride Well Water Industrial Fluoride Exposure Fluorinated Pharmaceuticals (Voriconazole
