Abstract
Objective: To understand the relationship between fluorosis and adult osteoarthritis through the investigation of fluorosis-afflicted villages.
Methods: X-ray radiography of right hands was performed on 227 adults over the age of 40 from fluorosis-afflicted villages, and adult osteoarthritis was diagnosed using accumulated scores based on the obtained results.
Results: The identification rate of osteoarthritis in fluorosis-afflicted regions was 59.03%, and the mean accumulated score was 3.85, both significantly higher than those for the control population (identification rate was 23.6%, mean accumulated score was 0.72); patients with osteoarthritis caused by fluorosis accounted for a considerable portion of the osteoarthritis population.
Conclusions: Fluorosis may lead to osteoarthritis, and also acts as a confounding factor of adult Kashin-Beck disease (KBD) in a portion of patients.

Correlation of pain and fluoride concentration in allogeneic hematopoietic stem cell transplant recipients on voriconazole
Supportive care guidelines recommend anti-mold prophylaxis in hematopoietic stem cell transplant (HSCT) recipients deemed high-risk for invasive fungal infection, leading to long-term use of voriconazole following allogeneic HSCT in patients that remain immunocompromised. Voriconazole has been associated with periostitis, exostoses, and fluoride excess in patients following solid organ transplant, HSCT

Association of fluoride in water for consumption and chronic pain of body parts in residents of San Kamphaeng district, Chiang Mai, Thailand
OBJECTIVE: To assess the dose response of fluoride exposure from water and chronic pain. METHODS: Using a retrospective cohort design, the study was conducted in two sub-districts of San Kamphaeng district, Poo-kha and On-tai. Five hundred and thirty-four residents aged ?50 years of age were interviewed about their sources of drinking

Total knee arthroplasty in a patient with skeletal fluorosis
Published reports on patients with skeletal fluorosis undergoing total knee arthroplasty are rare. Skeletal fluorosis is a chronic condition that occurs secondary to the ingestion of food and water that contain high levels of fluoride. Although fluorosis may be described as osteosclerotic and marble-like in appearance, features may also include

[Epidemiology and clinical study of endemic fluorosis in a village that has improved water for 40 years].
Objective: To investigate the control effect of water improvement for endemic fluorosis over a long period of time, the health status of the residents in the disease area and the restoration to health of endemic fluorosis patients. Methods: It was investigated that the water improvement lasting for 40 years and the rate

Fluoridation and the rheumatic diseases: a comparison of rhematism in Watford and Leigh
(1) A population sample in the town of Watford, Hertfordshire, has been examined clinically, radiologically, and serologically to determine the prevalence of chronic rheumatic diseases. A comparison has been made with a population sample in Leigh, Lancashire. The water supply in Watford had been fluoridated during the previous 5 years,

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.

"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.
