Abstract

To investigate the degree of myocardial damage resulting from endemic fluorosis, electrocardiograms of 136 skeletal fluorosis patients from an endemic fluorosis area were compared with electrocardiograms of a control group of 40 normal patients from a non-endemic fluorosis area. The results show that fluoride in drinking water consumed over time is harmful not only to bones and teeth but also to the cardiovascular system, and confirm the urgent need to lower the fluoride content of drinking water in endemic fluorosis areas.

  • The pathogenesis of endemic fluorosis: Research progress in the last 5 years.

    Fluorine is one of the trace elements necessary for health. It has many physiological functions, and participates in normal metabolism. However, fluorine has paradoxical effects on the body. Many studies have shown that tissues and organs of humans and animals appear to suffer different degrees of damage after long-term direct

  • Systematic impacts of fluoride exposure on the metabolomics of rats.

    Highlights The risk of chronic endemic fluorosis exists in many countries and regions. Comprehensive metabolomic analysis was used to study the effects of fluoride. Multivariate statistics were used to detect metabolite profile changes. Fluoride exposure caused amino acid, fatty acid, and energy metabolism disorders. Fluoride exposure caused oxidative stress,

    Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

  • Further observations on radiological changes of endemic food borne skeletal fluorosis

    Among radiological changes in 396 cases of foodborne skeletal fluorosis, from 4 endemic areas in Guizhou, China, osteoporosis, osteomalacia and impaired bone growth were seen in addition to previously recorded findings of osteosclerosis, bone prominences, joint changes and calcification of peripheral arteries. The deformity of genu valgum, a manifestation of

  • 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.

  • 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.

  • 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.
