Acute amitraz poisoning in adults: clinical features, laboratory findings, and management.
Amitraz is a formamidine pesticide widely used in agriculture and veterinary medicine as an insecticide and acaricide. Reports on amitraz poisoning in humans are not as prevalent as those in animals. Of human intoxications in the medical literature, the majority of intoxications are in children. The number of adult intoxications with amitraz is limited. ⋯ In spite of a rapidly progressing and life-threatening clinical picture, amitraz intoxication in humans carries a low morbidity and mortality when appropriate supportive treatment is given. No antidote has been developed for use in more serious cases. To prevent accidental ingestions, prominent and clear warning labels should be placed on its containers.

Case ReportsHyperosmolality: another indication for hemodialysis following acute ethylene glycol poisoning.
When given early, fomepizole has demonstrated an effective role in the treatment of ethylene glycol (EG) intoxication, often eliminating the need for hemodialysis (HD). Many indications for HD have been suggested for EG intoxication. ⋯ Despite early treatment with fomepizole and without the development of acidosis or renal insufficiency, the patient required HD for hyperosmolality and subsequent electrolyte imbalances. Indications for HD following EG intoxication are discussed.

Nitric oxide scavenging by hydroxocobalamin may account for its hemodynamic profile.
Antidotal doses of hydroxocobalamin are associated with transient increases in blood pressure in some animals and humans. These studies in anesthetized rabbits were undertaken to explore the possible mechanisms underlying the hemodynamic effects of hydroxocobalamin by investigating 1) possible hemodynamic effects of cyanocobalamin, which is formed on a molar-to-molar basis when hydroxocobalamin binds cyanide, and 2) the interference of hydroxocobalamin with the endothelial nitric oxide system. ⋯ These studies in anesthetized rabbits demonstrate that the moderate pressor effect of hydroxocobalamin is not related to the formation of cyanocobalamin but is very likely related to the scavenging of nitric oxide by hydroxocobalamin.

Case ReportsClinical course and toxicokinetic data following isolated citalopram overdose in an infant.
Despite the frequency of use of citalopram, its clinical effects and pharmacokinetics in overdose in the pediatric patient are not well described. We describe the clinical course and drug levels following the ingestion of citalopram by a 10-month-old female. ⋯ We report a case of citalopram poisoning in a 10-month-old infant with refractory seizures, and an absence of cardiovascular events with subsequent excellent outcome. The elimination of the parent drug corresponds to an approximate t1/2 of 15-20 h in this single case.

Evaluation of several clinical scoring tools in organophosphate poisoned patients.
The aim of this study was to evaluate the Acute Physiology and Chronic Health Evaluation (APACHE) II, III and Simplified Acute Physiology Score II (SAPS II) as predictors of severity of organophosphate poisoning (OPP). ⋯ The APACHE II, III and SAPS II clinical scoring tools seem to predict the severity of organophosphate poisoning, and may have prognostic value.
