Acute fluoride poisoning from a public water system.
BACKGROUND: Acute fluoride poisoning produces a clinical syndrome characterized by nausea, vomiting, diarrhea, abdominal pain, and paresthesias. In May 1992, excess fluoride in one of two public water systems serving a village in Alaska caused an outbreak of acute fluoride poisoning. METHODS: We surveyed residents, measured their urinary fluoride concentrations, and

Pharmacokinetic aspects of topical fluorides
Pharmacokinetic studies have revealed quantitative information about the bioavailability, rate of absorption, distribution, and clearance of fluoride following the use of fluoride-containing dentifrices, gels, varnishes, and solutions. It is concluded that following the use of topical fluoride products, variable amounts of fluoride are swallowed and absorbed into the systemic circulation--amounts which may be sufficient to produce acute

Sudden cardiac death from acute fluoride intoxication: the role of potassium.
The mechanism of sudden cardiac death following acute fluoride intoxication has been thought to result from profound hypocalcemia produced by the precipitation of calcium fluoride salts. In studies of a canine model, the onset of lethal ventricular arrhythmias was temporally more associated with an elevation of serum potassium than with

Acute fluoride poisoning in a New Mexico elementary school.
Thirty-four persons became ill with acute fluoride poisoning shortly after drinking water in an elementary school in Los Lunas, NM. The water supply of the school was supplemented with a concentrated sodium fluoride solution designed to raise fluoride levels in drinking water to 1 to 5 ppm. Two water samples

Exposure to excessive fluoride during hemodialysis
Discussion These data indicate that a patient maintained by hemodialysis in a community using fluoridated water may be exposed to a fluoride concentration higher than that present in tap water if the deionizer is allowed to become exhausted while the patient is being dialyzed. The concentration reached 520 uM in the
