  • Endemic genu valgum and other bone deformities in two villages of Mandla district in central India

    An epidemiological investigation was undertaken in the villages of Tilaipani and Hirapur located in Mandla District of Central India to determine the cause and extent of a peculiar skeletal deformity characterised by knock knee (genu valgum) occurring mainly among children. In Tilaipani, 74.4% of children and adolescents below age 20

  • Fluoride Sources, Toxicity and Fluorosis Management Techniques - A Brief Review.

    Highlights Overexposure to fluoride via drinking water causes several health effects including fluorosis Endemic fluorosis is still persisted in several countries even with advancement in research Most of fluorosis management techniques suggested in the past have come with their own drawbacks Defluoridation techniques based on aluminium materials pose serious

  • Lipid peroxidation and antioxidant enzyme status of adult males with skeletal fluorosis in Andhra Pradesh, India.

    Blood samples from 24 adult males, age 25 to 40, with endemic skeletal fluorosis, living in the Vaillapally village of the Nalgonda district, Andhra Pradesh, India, were examined and compared with samples from 15 matched controls for their antioxidant enzyme activity and lipid peroxidation. Elevated malondialdehyde (MDA) levels indicated an

  • Fluoride-induced oxidative stress in three-dimensional culture of OS732 cells and rats.

    Exposure to excessive fluoride poses a threat to human health, including increased susceptibility to developing the skeletal fluorosis. Despite its recognized importance as an endemic disease, little is known about how fluoride directly impacts on osteoblasts. We previously reported that fluoride-stimulating monolayer-cultured osteoblast proliferation or inhibiting cell viability depended on

  • Distribution of fluoride contamination in drinking water resources and health risk assessment using geographic information system, northwest Iran.

    Highlights Fluorosis is a considerable health problem worldwide. High concentrations fluoride above 3 mg l?1 may cause dental and skeletal fluorosis. HQ indicated health risk assessment in relation to F- concentration for children and adults were significant. The fluoride contamination must be reduced in this study area to decrease endemic

  • "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.

  • Fluoride & Spondylosis; Spondylitis

    Among individuals with skeletal fluorosis, the fluoride-induced changes to the spine, and the accompanying symptoms, can bear a close resemblance to spondylosis and spondylitis (as well as DISH). Spondylosis is a (non-inflammatory) degenerative disease of the spine marked by bony outgrowths (spurs) which can produce nerve cord compression. Spondylitis, by contrast, is an inflammatory form of arthritis that causes inflammation in the joints between the vertebrae. Whereas spondylosis is generally asymptomatic, spondylitis generally causes significant pain and stiffness in the spine.

  • 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.
