Abstract

This case of a patient with chronic fluoride intoxication, extensive osteosclerosis, and fluorotic radiculomyelopathy is believed to be the first reported froni the United States. The development of advanced fluorosis in this patient exposed to drinking vater with less than 4 ppm of fluoride was unusual and with probably a consequence of his excessive water intake.

Prolonged polydipsia may he hazardous to persons who live in areas where the levels of fluoride in drinking water are not those usually associated with significant fluorosis.

  • Endemic fluorosis with neurological complications in a Hampshire man

    We describe below a case of skeletal fluorosis occurring in a Hampshire man who presented with neurological complications, and whose condition was appreciably improved by operation. We believe that this is the first case of its kind to be reported from Britain, and also the first case of skeletal fluorosis

  • Skeletal fluorosis causing high cervical myelopathy

    Skeletal fluorosis is endemic in some parts of the world and is the result of life-long ingestion of high amounts of fluoride in drinking water. Its clinical presentation is characterized mostly by bone and dental changes with later ossification of many ligaments and interosseous membranes. We present a rare case of high cervical myelopathy

  • Skeletal fluorosis due to excessive tea and toothpaste consumption

    We describe the case of a 53-year-old woman who presented with a metatarsal fracture and was found to have a bone mineral density (BMD) T-score of +11 in the lumbar spine and +7.6 in the hip. Subsequent investigation revealed very high serum, urine and tissue fluoride levels, associated with excessive

  • An uncommon presentation of fluorosis

    A 70 years old farmer from Yemen was referred as a case of osteoarthritis of both knees for preoperative rehabilitation procedures. Six years before he developed progressive skeletal stiffness. By 70 years he became dependent for ambulation and many other self-care activities. He showed quadriparesis resulting from compression of spinal cord

  • Thoracic myelopathy from coincident fluorosis and epidural lipomatosis

    Skeletal fluorosis is rare in North America. It can present with back pain and extremity weakness. Immobilization of the spine and the extremity joints can occur. It is usually caused by abnormally increased oral fluoride intake over many years. Epidural lipomatosis is usually caused by idiopathic obesity or corticosteroid use.

  • 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.

  • 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.

  • Skeletal Fluorosis in the U.S.

    Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.

  • 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.
