  • [Skeletal fluorosis: a case report].

    The authors report a case of skeletal fluorosis described in a 60 years old man living in south-west Tunisian. The main clinical sign is a severe functional legs disability. Radiographic examination has shown a diffused osteocondensation, with cervical spine degenerative discopathy, a pelvis bilateral osteoarthritis and an interosseous membrane ossification

  • Continuing impacts on red deer from a volcanic eruption in 2011

    In June of 2011, the Puyehue–Cordon Caulle volcanic eruption deposited large amounts of ashes in Chile and Argentina. Although ashes were initially considered innoxious based on water leachates, we found clinical cases of fluoride intoxication in red deer (Cervus elaphus) and domestic herbivores in Argentina. The diagnosis was corroborated by

  • Early diagnosis and classification of professional fluorosis

    On the basis of evaluating the clinical course and supplementary method of examination carried out in 132 patients suffering of professional fluorosis and in 200 workers in the premorbid state the author proposes criteria of early diagnosis. Considering Zislin's classification of professional fluorosis, literature data and own findings the author

  • Fluorosis in some tribal villages of Dungarpur district of Rajasthan, India

    The prevalences of dental and skeletal fluorosis were observed in fifteen tribal villages of the Dungapur district of Rajasthan where the fluoride (F) concentration in drinking waters varies from 0.3 to 10.8 ppm. At 1.40 and 6.04 ppm mean F concentrations, 25.64% and 84.43% of school children (<16 years), and

  • [Relationship between fluoride exposure, orthopedic injuries and bone formation markers in patients with coal-burning fluorosis].

    Chronic exposure to fluoride is a public health problem worldwide. We explored the relationship between fluoride exposure, orthopedic injuries and bone formation markers alkaline phosphatase (ALP), bone Gla protein (BGP) in participants with coal-burning fluorosis in Hehua Village (coal-burning fluorosis endemic area) in Zhijin County of Guizhou Province and Zhangguan

  • Fluoride & Osteoarthritis

    While the osteoarthritic effects that occurred from fluoride exposure were once considered to be limited to those with skeletal fluorosis, recent research shows that fluoride can cause osteoarthritis in the absence of traditionally defined fluorosis. Conventional methods used for detecting skeletal fluorosis, therefore, will fail to detect the full range of people suffering from fluoride-induced osteoarthritis.

  • "Pre-Skeletal" Fluorosis

    As demonstrated by the studies below, skeletal fluorosis may produce adverse symptoms, including arthritic pains, clinical osteoarthritis, gastrointestinal disturbances, and bone fragility, before the classic bone change of fluorosis (i.e., osteosclerosis in the spine and pelvis) is detectable by x-ray. Relying on x-rays, therefore, to diagnosis skeletal fluorosis will invariably fail to protect those individuals who are suffering from the pre-skeletal phase of the disease. Moreover, some individuals with clinical skeletal fluorosis will not develop an increase in bone density, let alone osteosclerosis, of the spine. Thus, relying on unusual increases in spinal bone density will under-detect the rate of skeletal fluoride poisoning in a population.

  • Skeletal Fluorosis: The Misdiagnosis Problem

    It is a virtual certainty that there are individuals in the general population unknowingly suffering from some form of skeletal fluorosis as a result of a doctor's failure to consider fluoride as a cause of their symptoms. Proof that this is the case can be found in the following case reports of skeletal fluorosis written by doctors in the U.S. and other western countries. As can be seen, a consistent feature of these reports is that fluorosis patients--even those with crippling skeletal fluorosis--are misdiagnosed for years by multiple teams of doctors who routinely fail to consider fluoride as a possible cause of their disease.

  • Tea Intake Is a Risk Factor for Skeletal Fluorosis

    A number of recent studies have found that heavy tea drinkers can develop skeletal fluorosis - a bone disease caused by excessive intake of 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.
