Abstract

Case reports are presented of 8 patients with end stage renal disease who while undergoing dialysis received IV, excessive amounts of fluoride due to an unreported spill of hydrofluosilicic acid into the public water supply caused by cross connections in a treatment plant. Water used to mix dialysis solutions in this unit was treated only by a softening device; no reverse osmosis or deionization had occurred. The afebrile illness, predominantly characterized by hypotension, nausea, substernal pain, diarrhea, itching, and vomiting, developed after one to 2 hr of dialysis. One patient upon autopsy was found to have high fluoride levels in lung tissue (5.6 ppm), kidney (7.0 ppm), brain (0.9 ppm) and blood (4.9 ppm). When a chemical accident does occur, public health officials should be immediately informed so that dialysis units and End Stage Renal Disease Networks in particular can be promptly notified. Finally, it is recommended that water purification techniques such as reverse osmosis and deionization be used to ensure high quality dialysate.

    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

  • Effect of Fluoride on the Expression of 8-Hydroxy-2'-Deoxyguanosine in the Blood, Kidney, Liver, and Brain of Rats.

    Excessive exposure of fluoride not only leads to damage on bone, but also has an adverse effect on soft tissues. Oxidative DNA damage induced by fluoride is thought to be one of the toxic mechanisms of fluoride effect. However, the dose–response of fluoride on oxidative DNA damage is barely studied

    Rats were given Na18F as a radiotracer for F- at varying chemical dose rates by continuous i.v. infusion for 3 h. Blood fluoride was assessed 6-7 times over the infusion period, at the end of which the animals were sacrificed for determination of tissue fluoride distribution. At sublethal dosages, the

    In our experiment, the 1-month effects of caffeine (Caff) and fluoride (F) administered separately and together on nitric oxide and total antioxidant status in serum, brain, liver and kidney of rats were investigated. Also, the influence of caffeine on fluoride excretion with urine was studied. Thirty adult male Wistar rats

    Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching

  • Fluoride's Effect on Fetal Brain

    The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts

    An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out
