  • Prolactin rs1341239 T allele may have protective role against the brick tea type skeletal fluorosis

    OBJECTIVE: Prolactin (PRL) has been reported to be associated with increased bone turnover, and increased bone turnover is also a feature of skeletal fluorosis (SF). Autocrine/paracrine production of PRL is regulated by the extrapituitary promoter and a polymorphism in the extrapituitary PRL promoter at -1149 (rs1341239) is associated with disturbances

  • Skeletal changes in industrial and endemic fluorosis

    Fluorotic changes in bones and joints were evaluated in 105 aluminum workers and 20 residents of an endemic fluorosis region in India. The age of the workers averaged 51.2 years, and the duration of their exposure 18.2 years. The skeletal changes in the aluminum workers exhibited the same characteristics as

  • [Ossification of ligament and tendon attached around the elbow joint in diagnosis of skeletal fluorosis].

    Objective: To probe into the significance of osteosis of the junctions of ligaments and tendons around elbow joints for the diagnosis of skeletal fluorosis. Methods: Analyses were conducted on X-ray signs of elbow joints in 23 cases with skeletal fluorosis and fluoridated elbow joints identified in March 2011 in an

  • Recovery from skeletal fluorosis

    Kurland et al.(1) reported a fascinating case of skeletal fluorosis in a man who probably ingested significant quantities of fluoride from toothpaste. They report that after withdrawal of fluoride, there was a short initial period of rapid bone loss, followed by a prolonged period of slow BMD loss from the

  • Endemic Fluorosis in the Nellore District of South India.

      About the month of April 1936 the district health officer, Nellore, Dr. Lakshminarayana, had his attention drawn by the health inspectors of Podili and Darsi ranges of the Nellore district to a disease characterized by a definite train of symptoms and which was very prevalent in the district. The most

  • 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.

  • 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.

  • "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.

  • Fluoride Magnifies Impact of Repetitive Stress on Joints

    Research has repeatedly found that fluoride's effect on the skeleton is most pronounced in the bones and joints that undergo the greatest strain. Indeed, both the symptoms of fluorosis (i.e., joint pain and stiffness) as well as the radiological findings (e.g., exostoses, interosseuous membrane calcification) have been found to occur earliest, and most severely, in the joints

  • X-Ray Diagnosis of Skeletal Fluorosis

    In 1937, Kaj Roholm published his seminal study Fluorine Intoxication in which he described three phases of bone changes that occur in skeletal fluorosis. (See below). These three phases, which are detectable by x-ray, have been widely used as a diagnostic guide for detecting the disease. They describe an osteosclerotic bone disease that develops first in the axial skeleton (the spine, pelvis, and ribs), and ultimately results in extensive calcification of ligaments and cartilage, as well as bony outgrowths such as osteophytes and exostoses. Subsequent research has found, however, that x-rays provide a very crude measure for diagnosing fluorosis since the disease can cause symptoms and effects (e.g., osteoarthritis) before, and in the absence of, radiologicaly detectable osteosclerosis in the spine.
