  • Bone and joint pathology in fluoride-exposed workers

    Clinical and radiological investigations were performed for 2,258 aluminum workers exposed to fluoride for an average of 17.6 yr (standard deviation = 7.6). Changes in bone and joints were presented in detail in three groups: (1) exposed up to 5 yr (135 cases), (2) exposed from 6-32 yr (1,463 cases),

  • An uncommon presentation of fluorosis

    A 70 years old farmer from Yemen was referred as a case of osteoarthritis of both knees for preoperative rehabilitation procedures. Six years before he developed progressive skeletal stiffness. By 70 years he became dependent for ambulation and many other self-care activities. He showed quadriparesis resulting from compression of spinal cord

  • Industrial skeletal fluorosis: preliminary report on 61 cases from aluminum smelter

    SchIegel presented data on 61 cases of skeletal f1uorosis among workers of a Swiss aluminum factory. Of 350 cases ofìndustrial fluorosis reported in the world's literature, approximately 20 occcured in the smelting area of the aluminum industry. For processing aluminum from clay, cryolite (NaAlF6) is used as a fluxing agent.

  • 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

  • Skeletal fluorosis from instant tea

    INTRODUCTION: Skeletal fluorosis (SF) can result from prolonged consumption of well water with >4 ppm fluoride ion (F(-); i.e., >4 mg/liter). Black and green teas can contain significant amounts of F(-). In 2005, SF caused by drinking 1-2 gallons of double-strength instant tea daily throughout adult life was reported in

  • 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.

  • Similarities between Skeletal Fluorosis and Renal Osteodystrophy

    It is quite possible, and indeed likely, that some kidney patients diagnosed with renal osteodystrophy are either suffering from skeletal fluorosis or their condition is being complicated/exacerbated by fluoride exposure.

  • Fluoride & Spinal Stenosis

    Spinal stenosis is a narrowing of the spaces in the spine that results in pressure being placed on the spinal cord and/or nerve roots. Although stenosis can develop without symptoms, it may produce numbness, tingling, pain and difficulty in walking, as well as a heavy/tired feeling in the legs. It is estimated that 250,000 to 500,000 Americans currently have symptoms of spinal stenosis. Skeletal fluorosis is one cause of stenosis.
