Abstract
Efficiency of glutamic acid for therapy of early signs of occupational fluorosis was studied in workers engaged into cryolite production. The study proved that use of glutamic acid in occupational conditions prevents progressing of metabolic disorders. The results encourage recommendations to include glutamate into therapeutic and prophylactic nutrition of workers exposed to fluor compounds, into nutritive additions according to special recipe.

Insights into material and structural basis of bone fragility from diseases associated with fractures: how determinants of the biomechanical properties of bone are compromised by disease.
Minimal trauma fractures in bone diseases are the result of bone fragility. Rather than considering bone fragility as being the result of a reduced amount of bone, we recognize that bone fragility is the result of changes in the material and structural properties of bone. A better understanding of the

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

Fluorosis by the Ministry of Health & Family Welfare, National Health, India.
Introduction Fluorosis is a crippling disease resulted from deposition of fluorides in the hard and soft tissues of body. It is a public health problem caused by excess intake of fluoride through drinking water/food products/industrial pollutants over a long period. Ingestion of excess fluoride, most commonly in drinking-water affects the teeth

Histopathological assessment of endemic skeletal fluorosis
Nine patients with skeletal fluorosis were subjected to iliac crest biopsy because they presented with stiffness and bone pains. The histopathological findings are correlated with the clinical course, X-ray and laboratory data. All but one of the patients showed an increase in bone surfaces lined by osteoid and in these

Impact of Community Defluoridation on a Village Endemic for Hydric Fluorosis in Rural Karnataka, India.
Introduction: Excessive intake of fluorides can lead to the development of fluorosis, a serious public health issue in India. The objective of this study was to assess the impact of community defluoridation in preventing fluorosis in Kaiwara village. Methodology: This community interventional trial was conducted in Kaiwara

"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.

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.

Skeletal Fluorosis & Individual Variability
One of the common fallacies in the research on skeletal fluorosis is the notion that there is a uniform level of fluoride that is safe for everyone in the population. These "safety thresholds" have been expressed in terms of (a) bone fluoride content, (b) daily dose, (c) water fluoride level, (d) urinary fluoride level, and (e) blood fluoride level. The central fallacy with each of these alleged safety thresholds, however, is that they ignore the wide range of individual susceptibility in how people respond to toxic substances, including fluoride.

Fluoride Reduces Bone Strength Prior to Onset of Skeletal Fluorosis
The majority of animal studies investigating fluoride's impact on bone strength have found that fluoride has either no effect, or a detrimental effect, on bone strength. Importantly, several of the animal studies that have found fluoride reductes bone strength have reported that this reduction in strength occurs before signs of skeletal fluorosis
