Abstract
Since 1958 the Department of Medicine, Patiala, has been actively engaged in epidemiological, clinical amd biochemical studies of endemic fluorosis in Punjab, one of the most highly endemic areas in the world. Extensive data on dental, skeletal and neurological aspects of fluorosis have been fully reported in our earlier studles (1-5). The object of the present communication is to evaluate the role of various lectors associated with F toxicity. Even where F levels in the water are identical, variations in the incidence of F
intoxication clearly point to the existence of causative factors in addition to fluoride.

Fluoride exposure and bone status in patients with chronic intestinal failure who are receiving home parenteral nutrition
BACKGROUND AND OBJECTIVE: Metabolic bone disease is frequent in chronic intestinal failure. Because fluoride has a major effect on bones, the status of both fluoride and bone was studied in long-term home parenteral nutrition (HPN) patients. DESIGN: We studied 31 adults aged (x +/- SD) 56.3 +/- 15.1 y, mainly

Fluorosis as a probable factor in metabolic bone disease in captive New Zealand native frogs (Leiopelma species)
This report describes the investigations into the cause and treatment of metabolic bone disease (MBD) in captive native New Zealand frogs (Leiopelma spp.) and the role of fluoride in the disease. MBD was diagnosed in Leiopelma archeyi and Leiopelma hochstetteri in 2008 at three institutions: Auckland Zoo, Hamilton Zoo, and

Non-Endemic Skeletal Fluorosis: Causes And Associated Secondary Hyperparathyroidism (Case Report and Literature Review).
Highlights Fluorocarbon “huffing” is an under-appreciated cause of skeletal fluorosis (SF) We present a SF case with hyperparathyroidism, osteosclerosis, and osteomalacia SF may go undetected due to variation in symptoms, radiology, and biochemistry Dietary calcium, prior bone health, and skeletal F exposure influence SF features SF is common in

[Genetic factors predisposing to occupational fluorosis].
Having analyzed a total amount of all systems, the authors specified the most important genetic markers predisposing to chronic flour intoxication: the patients demonstrated higher frequency of ACP1*A and PGM1*1-alleles, phenotypes of acid phosphatase AA, of phosphoglucomutase 1+1+ and 2+2+, of dry cerumen consistence--d. The results could help to improve

Fluorine and Fluorosis [June 1944].
Excerpt The first account of mottled enamel in human beings was given in 1902 by Eager of the United States Public Health Service who noticed its frequency among Italian emigrants from Naples. Black and McKay (1916) found it occurring in various parts of the U.S.A. and described it more fully in

Fluoridation, Dialysis & Osteomalacia
In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

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.

Factors which increase the risk for skeletal fluorosis
The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

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.
