Abstract
Results are reported of a comprehensive investigation into fluoride levels in drinking water and other environmental characteristics, and their relation to endemic fluorosis, in Hohhot Region, Inner Mongolia.
Excerpt:
Hohhot has three counties including 45 townships. In 28 townships are located 412 villages which are the fluorosis endemic regions. The people threatened by fluorosis are 310,000 in number. Of these it is estimated that 246,015 suffer from fluorosed teeth (over 79%) and 41,235 have skeletal fluorosis (13.3%).

Methoxyflurane toxicity: historical determination and lessons for modern patient and occupational exposure.
Aim: Historically methoxyflurane was used for anaesthesia. Evidence of nephrotoxicity led to abandonment of this application. Subsequently, methoxyflurane, in lower doses, has re-emerged as an analgesic agent, typically used via the Penthrox inhaler in the ambulance setting. We review the literature to consider patient and occupational risks for

Fluoride osteosclerosis from drinking water
1. A case of osteosclerosis, exhibiting in addition mottled enamel, severe anemia showing no response to anti-anemic therapy, and bilateral renal lesions is reported. 2. The diagnosis of fluoride osteosclerosis was proved by the history of a long residence in areas of endemic fluorosis and by fluorine analysis of the patient's

Osteo-dental fluorosis in relation to nutritional status, living habits, and occupation in rural tribal areas of Rajasthan, India
A cross-sectional survey of 18,621 adults of both sexes living in rural tribal areas of the Dungarpur and Udaipur districts of Rajasthan, India was conducted to correlate the prevalence of osteo-dental fluorosis with nutritional status, living habits, and occupation. The mean fluoride (F) concentration in drinking water sources ranged from

Brick tea fluoride as a main source of adult fluorosis
An epidemiological survey was conducted in Naqu County, Tibet in September 2001 to investigate the manifestations of fluorosis in adults caused by the habitual consumption of brick tea. Profiles were obtained for the total daily fluoride intake, environmental fluoride levels and average urinary fluoride concentration, and a physical examination and a

Why did the ancient inhabitants of Palmyra suffer fluorosis?
The skeletal remains uncovered from the 2nd and 3rd century underground tombs of Palmyra, Syria, retain traces of arthritis and mottled enamel. A brown discoloration was also observed in the teeth. In order to clarify that these facts can be related to fluorosis, the teeth excavated from Tomb C and

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.

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.

Gastrointestinal Problems Among Individuals with Skeletal Fluorosis
Humans suffering from skeletal fluorosis are known to suffer from an increased occurrence of gastrointestinal disorders. When fluoride intake is reduced, these gastrointestinal problems are among the first symptoms to disappear. The following are some of the studies that have examined this issue: "It is clear from the observations presented in this article

Fluoride & Rheumatoid Arthritis
The symptoms of skeletal fluorosis can closely resemble rheumatoid arthritis (RA), and thus individuals with fluorosis can "easily be mistaken" as having RA. In addition, clinical research on fluoride-treated osteoporosis patients has found that fluoride exposure can exacerbate pre-existing RA, and recent research shows that the levels of fluoride found in the blood of the general population (19-57 ppb) are sufficient to effect an enzyme (15-lipoxygenase) implicated in the inflammatory process of RA.
