Abstract

We report a case of fluorosis due to high water and soil contents in a 23-year-old Algerian woman. The condition, which is infrequent at this age, was promoted by chronic renal failure due to a congenital renal malformation. Roentgenograms showing osteosis with increased bone density were suggestive of fluorosis rather than renal osteodystrophy. Bone tissue fluoride assay confirmed fluorosis. Histomorphometric analysis of bone biopsy specimens showed mixed lesions: major osteocondensation due to bone fluorosis and morphologic and dynamic osteomalacia related to the chronic renal failure.

    Report on a 70-year-old male with bone fluorosis which was ascertained radiologically, by section and fluor analysis in the bone ash. With empty professional anamnesis as cause was found the presence of a chronic renal insufficiency with simultaneously increased fluor content of drinking water. The decreased renal excretion of fluoride

  • Increased fluoride content in the femur growth plate and cortical bone of uremic rats

    In chronic renal insufficiency (CRI), serum levels of fluoride (F-) are elevated. However, there is limited information about the effects of F- on bone in CRI. In this study, we determined whether F- content in mineralizing tissue (growth plate, cortical bone, and bone marrow of the femur) is affected by

  • Effects of fluoride on bone in chronic renal failure

    Fluoride is concentrated in the bones of patients with chronic renal failure when fluoridated water is used during hemodialysis. Excessive osteoid is produced that is not normally mineralized and severe osteomalacia occurs. Electron microscopical examination of iliac crest bone biopsy specimens from four patients suggests that fluoride induces the synthesis

  • 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

  • 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

  • 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

  • Fluoride & Osteomalacia

    One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid content of bone. Osteoid is unmineralized bone tissue. When bones have too much of it, they become soft and prone to fracture -- a condition known as osteomalacia. As shown below, fluoride has repeatedly been

    Despite the well known fact that individuals with kidney disease are at much higher risk of fluoride toxicity than the general population, there has yet to be any attempt in the United States, or any other country that practices mass-scale water fluoridation to determine the prevalence of fluoride-related effects (e.g.,

  • Skeletal Fluorosis in the U.S.

    Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.
