Abstract

The ossification of the posterior longitudinal is always responsible of cervical myelopathy. Radiological study and the CT scan, are able to precise the level, the morphologic and associated abnormalities of this lesion. Two cases of ossification of the posterior longitudinal ligamentum with cervical myelopathy are reported. The radiologic studies determined the etiology, in the first case, it was fluorosis and the second DISH disease.

  • MRI features of spinal fluorosis: results of an endemic community screening

    Objectives: Fluorosis is endemic in many parts of the world. However community studies on MRI features of fluorosis are lacking. The aim of this study was to determine MRI features of spinal changes in a community with endemic fluorosis in the Thar Desert Pakistan. Methodology: Randomly selected adults from the Village

  • Health problems in fluoride endemic areas of Gaya District

    Fluoride (F) was estimated in the groundwater of six blocks (Bodh Gaya, Manpur, Wazirganj, Belaganj, Amas, and Bankebazar) of Gaya District, Bihar, for different physio-chemical properties e.g. pH, total dissolved solids(TDS), conductivity, turbidity, total hardness (TH), calcium, magnesium, iron and fluoride. Morever 93 blood samples from different age groups including

  • Industrial fluoride pollution: Chronic fluoride poisoning in Cornwall Island cattle.

    An aluminum plant on the south bank of the St. Lawrence river, southwest of Cornwall Island, Ontario, Canada, has emitted 0.816 metric tons of fluoride daily since 1973; considerably higher amounts were emitted from 1959 to 1973. The plant has been designated as the "major source of fluoride emissions impacting

    The aim of this research is to investigate the role of the occupational risks in the development of pain syndromes of the locomotor system in workers employed in basic workplaces at aluminum potrooms, basing on the periodic health screenings data. It has been determined that working under the conditions of

  • Continuing impacts on red deer from a volcanic eruption in 2011

    In June of 2011, the Puyehue–Cordon Caulle volcanic eruption deposited large amounts of ashes in Chile and Argentina. Although ashes were initially considered innoxious based on water leachates, we found clinical cases of fluoride intoxication in red deer (Cervus elaphus) and domestic herbivores in Argentina. The diagnosis was corroborated by

  • "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 & 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.
