  • 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 due to inhalation abuse of a difluoroethane-containing computer cleaner

    Skeletal fluorosis (SF) is endemic in many countries and millions of people are affected worldwide, whereas in the United States SF is rare with occasional descriptions of unique cases. We report a 28-year-old American man who was healthy until two years earlier when he gradually experienced difficulty walking and an abnormal gait,

  • Non-Endemic Skeletal Fluorosis: Causes And Associated Secondary Hyperparathyroidism (Case Report and Literature Review).

    Highlights Fluorocarbon “huffing” is an under-appreciated cause of skeletal fluorosis (SF) We present a SF case with hyperparathyroidism, osteosclerosis, and osteomalacia SF may go undetected due to variation in symptoms, radiology, and biochemistry Dietary calcium, prior bone health, and skeletal F exposure influence SF features SF is common in

  • Brick tea fluoride as a main source of adult fluorosis

    An epidemiological survey was conducted in Naqu County, Tibet in September 2001 to investigate the manifestations of fluorosis in adults caused by the habitual consumption of brick tea. Profiles were obtained for the total daily fluoride intake, environmental fluoride levels and average urinary fluoride concentration, and a physical examination and a

  • Elevated fluoride levels and periostitis in pediatric hematopoietic stem cell transplant recipients receiving long-term voriconazole

    Azole therapy is widely utilized in hematopoietic stem cell transplant (HCT) recipients for the treatment of aspergillus. Complications of voriconazole treatment related to its elevated fluoride content have been described in adults, including reports of symptomatic skeletal fluorosis. We review fluoride levels, clinical, and laboratory data in five pediatric HCT recipients

  • 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.

  • Fluoride Content of Tea

    Tea, particularly tea drinks made with lower quality older leaves, contain high levels of fluoride. Because of these high levels, research has found that individuals who drink large amounts of tea can develop skeletal fluorosis -- a painful bone disease caused by excessive fluoride intake. Since skeletal fluorosis is often misdiagnosed by

  • Fluoride & DISH (Diffuse Idiopathic Skeletal Hyperostosis)

    Among individuals with skeletal fluorosis, the fluoride-induced changes to the spine, and the accompanying symptoms, can bear a close resemblance to DISH (Forestier's Disease). Some authors report that skeletal fluorosis can so closely resemble that DISH that the only way to distinguish the two would be to conduct an invasive bone biopsy. No studies have ever been conducted to determine what role, if any, fluoride plays in the development of DISH.
