Abstract
The occupational fluorosis risk factors were estimated in a three- stage study among the workers of aluminum and cryolite plants using dennatoglyphics as a genetic marker. This study helped: 1) to establish the existence of genetic predisposition to fluorosis and develop criteria for estimating it, and 2) to prove that predisposition to fluorosis was associated with the same dermatoglyphic features in the workers of both industrial groups. Multifactorial analysis of the set of 15 genetic and non-genetic factors was performed with the help of pattern recognition methods, and demonstrated reliable (90-100%) discrimination between two groups of workers: those who had developed fluorosis and those who had not. Each of the 15 risk factors under study was examined for the degree and the direction of influence. A PC software program was developed in the course of the study, making possible the estimation of individual predisposition to the disease. The method was used to investigate 397 disease- free workers in the electrolysis shop of an aluminum plant. Predisposition to fluorosis was discovered in 22 of them (5.5%)

Fluoride metabolism in patients with chronic renal failure
Studies of fluoride metabolism were carried out in patients with chronic renal failure by determining fluoride balances for several weeks. The fluoride intake was due to the analyzed fluoride content of the diet and of the drinking water. The effect of aluminum hydroxide on fluoride metabolism was investigated because this

Using drawing tests to measure intelligence in children from areas impacted by combined Al-F endemic toxicosis (Shuicheng, Guizhou).
Measurements of intelligence via drawing tests have been conducted to examine the intelligence development of children from regions affected by combined AIF endemic toxicosis. A selected number of 196 children between 6.5 and 12 years of age participated in the testing. Across all age groups, the average IQ level of children from

[The change of thyroid functlon from the children with fluoride aluminum combined toxicosis in Shuicheng Area of Guizhou].
The levels of serum T3, T4 and TSH were analyzed in the children with fluoride aluminum combined toxicosis in Shuicheng area of Guizhou as compared with the children without fluoride-aluminum combined toxicosis. The results showed that serum T4 content decreased in the children with fluoride aluminum combined toxicosis (103.9±15.9 nmol/L

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

Neuroprotective effect of berberine against environmental heavy metals-induced neurotoxicity and Alzheimer's-like disease in rats.
Highlight The environmental neurotoxicity of heavy metals and trace elements. The anti-inflammatory/antioxidant properties of berberine against the neurodegenerative disorders. Beberine as multipotent anti-Alzheimer like disorder compound. Heavy metals are reported as neurodegenerative disorders progenitor. They play a role in the precipitation of abnormal ß-amyloid protein and hyper-phosphorylated tau, the main hallmarks

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.

Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur

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

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.
