  • Fluoride-related bone disease associated with habitual tea consumption

    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

  • Renal failure and fluorosis

    Two patients had a combination of renal insufficiency and systemic fluorosis. One had bilateral vesicoureteral reflux and recurrent pyelonephritis, with resulting renal atrophy; the other had probable renal dysgenesis of indeterminate origin. Both patients had polydipsia, polyuria, and markedly reduced renal function. Both also had clinical and roentgenographic evidence of

  • Skeletal fluorosis in humans: a review of recent progress in the understanding of the disease

    Endemic skeletal fluorosis is a chronic metabolic bone and joint disease caused by ingesting large amounts of fluoride either through water or rarely from foods of endemic areas. Fluoride is a cumulative toxin which can alter accretion and resorption of bone tissue. It also affects the homeostasis of bone mineral

  • Fluoride osteosclerosis from drinking water

    1. A case of osteosclerosis, exhibiting in addition mottled enamel, severe anemia showing no response to anti-anemic therapy, and bilateral renal lesions is reported. 2. The diagnosis of fluoride osteosclerosis was proved by the history of a long residence in areas of endemic fluorosis and by fluorine analysis of the patient's

  • Subacute fluorosis

    A young woman presented with a novel multisystem disease: painful periostitis, osteosclerosis, hypertension, and renal dysfunction. The similarity of some of this clinical picture to fluoride intoxication led to the discovery of massively elevated fluoride levels in serum, urine, and bone. Although initially an enigma, the source of fluoride was

    The available evidence suggests that some patients wtih long-term renal failure are being affected by drinking water with as little as 2 ppm fluoride. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers and if fluoride is indeed the cause. It would seem prudent, therefore, to monitor the fluoride intake of patients with renal failure living in high fluoride areas.

  • Kidney Patients Are at Increased Risk of Fluoride Poisoning

    It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

  • 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

  • Skeletal Fluorosis & Individual Variability

    One of the common fallacies in the research on skeletal fluorosis is the notion that there is a uniform level of fluoride that is safe for everyone in the population. These "safety thresholds" have been expressed in terms of (a) bone fluoride content, (b) daily dose, (c) water fluoride level, (d) urinary fluoride level, and (e) blood fluoride level. The central fallacy with each of these alleged safety thresholds, however, is that they ignore the wide range of individual susceptibility in how people respond to toxic substances, including fluoride.

  • Factors which increase the risk for skeletal fluorosis

    The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.
