A description of the fluoride overfeed in Hooper Bay, Alaska, that resulted in the first reported death due to fluoride toxicity caused by drinking water from a community water system.
Delayed fatal hyperkalemia in a patient with acute fluoride intoxication.
A 19-year-old man presented with acute fluoride poisoning. Initially his serum electrolytes were normal, but two hours later he developed ECG evidence of hyperkalemia followed by refractory ventricular fibrillation, suggesting that hyperkalemia may be important in the cardiotoxicity of acute fluoride intoxication. Treatment of fluoride-induced hyperkalemia consists of removal of
[Analysis on clinical characteristics of 316 patients with hydrofluoric acid burns].
Objective: To investigate the clinical characteristics of patients with hydrofluoric acid (HF) burns. Methods: Clinical data of 316 patients with HF burns admitted to Zhejiang Quhua Hospital from January 2004 to December 2016 were retrospectively analyzed. Patients were divided into non and mild poisoning group (NMP, n=157), moderate poisoning group (MP,
Sodium fluoride produces a K+ efflux by increasing intracellular Ca2+ through Na+-Ca2+ exchange.
Acute fluoride intoxication increases intracellular calcium (Cai), manifested by increased twitch tension in cardiac muscle, and by potassium efflux (mediated by Ca2+-dependent K+ channels) in fluoridated erythrocytes. Fluoride, like isoproterenol, stimulates adenylate cyclase, and could increase Cai via the effects of cAMP on Ca2+ channels. However, while the inotropic effects
Fluoride ingestion in children: a review of 87 cases.
All cases of fluoride ingestion in children younger than 12 years old reported to the Rocky Mountain Poison Center between January 1 and December 31, 1986, were retrospectively reviewed. Eighty-seven cases were identified. Eighty-four cases involved accidental ingestion of dental fluoride products in the home (tablets, drops, rinses) in children
Fluoride in dental products: safety considerations
This review summarizes the nature of acute fluoride toxicity, its time-course, and the fluoride doses that are involved. The generally accepted "certainly lethal dose" range for 70 kg adults, i.e., from 5 to 10 g of sodium fluoride or from 32 to 64 mgfluoride/kg, is discussed. Based on recent case reports of fluoride-induced fatalities, it is concluded
