Abstract

Workers of electrolytic departments at the Novokuznetsk aluminum plant were found to suffer not only from fluorosis (28.2) per cent), but also from degenerative-dystrophic affection of the skeleton (87.7 per cent). The workers of a control group who were not exposed to a chronic action of fluorine compounds the degenerative-dystrophic lesions of the skeleton are encountered on much rarer occasions (58.1 per cent). In workers of the aluminum plant there prevailed the affection of joints in the upper extremities, largely of a symmetric nature. Of decisive influence on the development of degenerative-dystrophic lesions of the skeleton was the service-record at the plant. A careful statistical analysis of the frequency of skeletal degenerative-dystrophic lesions in workers with fluorosis and in those who only had to deal with fluorides showed fluorosis to be of no significance in the development of degenerative-dystrophic affections of the joints and the spine.

    Analysis of X-ray images of 397 patients suffering from fluorosis showed that 94.0% of cases exhibit degenerative-dystrophic impairments of the lumbar spine; 65.0% of cases – calcification of the anterior longitudinal ligament; and 91.0% of cases – impairments in the form of epicondylitis, periarthrosis, and deforming arthrosis. Impairment of the

    Radiographs of 80 patients with severe endemic fluorosis of coal-burning type [CBEF] - 49 males and 31 females aged 30 to 70 years - were analysed to examine the changes to the bone substance, peripheral structure of bone, and joints. The changes to bone substance were: 1) osteosclerosis type, 62

  • Industrial fluorosis [Vischer et al.]

    Summary Chronic fluorosis alters bone structure, leads to odd exostosis, to osseous appositions, to ossification of ligaments and tendons and their insertions. This can cause pain and discomfort. Radiological examination usually leads to the correct diagnosis; the most constant changes were found in films of elbows and forearms. Such films may

  • 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.

  • 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 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.
