Abstract
We report a case of spinal cord compression in a Mexican immigrant due to vertebral osteosclerosis from chronic fluoride intoxication. Endemic fluorosis is acquired through drinking water. Groundwater sources with high fluoride content occur worldwide. The epidemiology, metabolism, and clinical features of fluorosis are reviewed. Greater physician awareness of this entity is important to identify correctly patients with this unusual and potentially devastating clinical disorder.

Skeletal fluorosis from brewed tea.
BACKGROUND: High fluoride ion (F(-)) levels are found in many surface and well waters. Drinking F(-)-contaminated water typically explains endemic skeletal fluorosis (SF). In some regions of Asia, however, poor quality "brick tea" also causes this disorder. The plant source of brick, black, green, orange pekoe, and oolong tea, Camellia

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

Three-year effectiveness of intravenous pamidronate versus pamidronate plus slow-release sodium fluoride for postmenopausal osteoporosis
All currently available and approved therapies for osteoporosis inhibit bone resorption. But, despite their great value, antiresorptive agents are generally not associated with dramatic increases in bone mass. In light of these data, the aim of our prospective, placebo-controlled, randomized clinical trial, with a 3-year follow up, was to examine

Fluoride toxicosis in immature herbivorous domestic animals living in low fluoride water endemic areas of Rajasthan, India: An observational survey
Susceptibility to fluoride toxicosis in the form of osteo-dental fluorosis was observed among 435 immature herbivorous domestic animals living in areas with less than 1.5 ppm fluoride in the drinking water. These animals included 78 buffaloes (Bubalus bubalis), 89 cattle (Bos taurus), 30 donkeys (Equus asinus), 21 horses (Equus caballus),

Fluoride exposure may accelerate the osteoporotic change in postmenopausal women: animal model of fluoride-induced osteoporosis
Carbonic anhydrase is a key enzyme for initiating the crystal nucleation, seen as “the central dark line” in the crystal structure in calcified hard tissues such as tooth enamel, dentin and bone. Both estrogen deficiency and fluoride exposure adversely affected the synthesis of this enzyme in the calcifying hard tissues.

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.
