Abstract
With the expansion of certain types of industrialization into agricultural areas, fluorosis in livestock has become an important toxicologic problem in some places in the United States and many other countries. Fluorine has beneficial effects when ingested in small amounts, but toxic and adverse effects when ingested in excessive amounts. Many sources may contribute to the total fluorine intake of animals. Various factors influence biologic responses of livestock to ingested fluorides. Fluorosis can be correctly diagnosed and evaluated by qualified individuals. Some methods and procedures are helpful in alleviating fluorine toxicosis. Several programs may be used for settlements and solutions of fluorosis problems. Standards and a comprehensive guide for use in diagnosing and evaluating fluorosis in livestock has been compiled.

Skeletal fluorosis mimicking seronegative arthritis
Fluorosis is endemic in certain parts of the world, especially the Asian subcontinent (1). We report an unusual presentation of fluorosis mimicking seronegative spondyloarthritis. Although fluorosis is known to cause irritable bowel syndrome-like disorder and joint pain, this could be wrongly diagnosed as a case of seronegative arthritis. Case report A 35-year-old

Secondary hyperparathyroidism in patients with endemic skeletal fluorosis
Investigation of 20 patients with skeletal fluorosis showed that five had clear evidence of secondary hyperparathyroidism. The hyperactivity of the parathyroid glands in skeletal fluorosis in the presence of decreased solubility of the bone mineral (fluoroapatite) strongly suggests that it is a compensatory attempt to maintain a normal extracellular ionized calcium equilibrium.

Fluoride in drinking water and the bone mineral density of women in Taiwan
BACKGROUND: The current evidence on effect of fluoridation in drinking water on bone is inconsistent. This study was undertaken to assess the effect of fluoride concentration in drinking water on bone mineral density (BMD) in Taiwanese women. METHODS: The study subjects included 248 women aged > or = 40 years

Skeletal fluorosis in a resettled refugee from Kakuma refugee camp.
“I suspected some contamination of the water of the much-frequented street pump in Broad Street, near the end of Cambridge Street”, said John Snow, about the contaminated water pump of the cholera outbreak of 1854, in London, UK.1 In September, 2015, a Somalian man aged 46 years presented to a refugee

"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.

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 & 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.
