Abstract

(1) Fluoride concentrations were determined for autopsy samples of rib, sacrum, ilium, vertebra, adhering soft tissue, and rib marrow from a patient suffering from rheumatoid (ankylosing) spondylitis of 10 years’ duration. The fluoride concentrations were not increased above normal levels. In this case, the increased bone density seen in this disease was not the result of increased skeletal fluoride deposition.

(2) A tabular comparison of rheumatoid spondylitis, crippling fluorosis, and metastatic carcinoma is presented.

  • Ancient and recent evidence of endemic fluorosis in the Naples area

    Endemic fluorosis induced by high concentrations of natural fluoride in groundwater and soils is a major health problem in several countries, particularly in volcanic areas. The early stages of skeletal fluorosis, a chronic metabolic bone and joint disease rarely considered in palaeopathological diagnoses, are often misdiagnosed in endemic areas. In

  • Paleopathology of skeletal fluorosis

    Skeletal fluorosis is one of a range of conditions causing excessive ossification and joint ankylosis in skeletons. It is rarely considered, however, in differential diagnoses of palaeopathological lesions. This paper considers the identification of skeletal fluorosis in a skeletal sample from the island of Bahrain, Arabian Gulf, dating to ca.

  • Enduring fluoride health hazard for the Vesuvius area population: the case of AD 79 Herculaneum

    BACKGROUND:  The study of ancient skeletal pathologies can be adopted as a key tool in assessing and tracing several diseases from past to present times. Skeletal fluorosis, a chronic metabolic bone and joint disease causing excessive ossification and joint ankylosis, has been only rarely considered in differential diagnoses of palaeopathological

  • Rapid-onset diffuse skeletal fluorosis from inhalant abuse

    Case: A thirty-year-old man presented with severely debilitating left hip pain and stiffness. Radiographs demonstrated diffuse osteosclerosis and heterotopic bone formation with near ankylosis of the left hip. The patient underwent successful joint-preserving surgery to restore hip range of motion. After disclosing a history of inhalant abuse, which was confirmed

  • Alert on long-term lumbago and skelalgia not responsive to anti-rheumatic pharmacotherapy

    In our work we have often dealt with patients who were diagnosed with “rheumatic or rheumatoid arthritis” in rural basic medical units or certain hospitals. A minority of those patients did have rheumatoid arthritis, but most of them did not improve with anti-rheumatic pharmacotherapy for multiple years; instead, their conditions

  • 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.

  • 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.

  • Estimated "Threshold" Doses for Skeletal Fluorosis

    For over 40 years health authorities stated that in order to develop crippling skeletal fluorosis, one would need to ingest between 20 and 80 mg of fluoride per day for at least 10 or 20 years. This belief, however, which played an instrumental role in shaping current fluoride policies, is now acknowledged by the National Academy of Sciences (NAS) and other US health authorities to be incorrect.

  • 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
