Abstract
A 54-year-old female resident of Wellston, Okla, was found to have osteosclerosis on a routine chest roentgenogram. Subsequent investigation disclosed the cause of her osteosclerosis to be fluorosis secondary to the ingestion of well water containing 429 mumol/L of fluoride (recommended levels, 11 to 58 mumol/L). Water samples were also obtained from the 12 wells on properties adjacent to the index case. In three other wells, all at similar depths as the well of the index case, the fluoride concentration of the water was greater than 212 mumol/L. Urine samples from members of the four households who obtain their drinking water from these wells contained elevated urinary fluoride levels. Thus, fluorosis may develop in certain areas of the United States as a result of the natural occurrence of fluoride in the groundwater. Consequently, in known endemic areas, it would appear reasonable to measure the fluoride concentration of the well water at the time of drilling.

Revisiting Fluoride in the Twenty-First Century: Safety and Efficacy Considerations.
Over 100 years of scientific literature is available which describes the long relationship between dentistry and the many possible applications of fluoride anion (F-) as successful therapeutic strategies. To date, systemic introduction of fluoride via water, milk and salt fluoridation, and fluoride-containing tablets, has been employed. Post-eruption topical fluoride products

Voriconazole-associated periostitis: Pathophysiology, risk factors, clinical manifestations, diagnosis, and management.
Voriconazole use has been associated with osteoarticular pain and periostitis, likely due to high fluoride content in the drug formulation. This phenomenon has been described primarily with high dosage or prolonged course of voriconazole therapy in immunocompromised and transplant patient populations. Patients typically present with diffuse bony pains associated with

An Outbreak of Industrial Fluorosis in Cattle.
IT may be recalled that in the "Discussion on Fluorosis in Man and Animals" by this Section in February 19411 the occurrence of severe fluorosis in cattle was described on farms in the vicinity of brickworks in Bedfordshire. The purpose of the present communication is to report a similar occurrence

Reducing the off-target endocrinologic adverse effects of azole antifungals—can it be done?
Highlights Azole antifungals are associated with off-target endocrinologic adverse events. Skeletal fluorosis, pseudohyperaldosteronism, adrenal insufficiency, hyponatraemia and hypogonadism are reported. Clinical and biochemical monitoring may play a role in prevention and progression. Novel azoles offer therapeutic advantages due to greater selectivity of binding to fungal CYP51. Integration of pharmacogenomics

Fluoride-related bone disease associated with habitual tea consumption
Acquired osteosclerosis is a rare disorder of bone formation but an important consideration in adults with sclerotic bones or elevated bone density results. In such patients, malignancy, hepatitis C, and fluorosis should all be considered when making a diagnosis. We describe 4 patients evaluated at our Metabolic Bone Disease Clinic

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.

"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.

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 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.
