Randomized Controlled Trial Clinical TrialThe effects of fresh frozen plasma on cholinesterase levels and outcomes in patients with organophosphate poisoning.
The aim of this study is to determine the effects of fresh frozen plasma, as a source of cholinesterase, on butyrylcholinesterase (BuChE; plasma or pseudo cholinesterase) levels and outcomes in patients with organophosphate poisoning. ⋯ Fresh frozen plasma therapy increases BuChE levels in patients with organophosphate poisonings. The administration of plasma may also prevent the development of intermediate syndrome and related mortality. Plasma (fresh frozen or freshly prepared) therapy may be used as an alternative or adjunctive treatment method in patients with organophosphate pesticide poisoning, especially in cases not given pralidoxime. Further randomized controlled and animal studies are required to infer a definitive result.

Case ReportsUnusual D-lactic acid acidosis from propylene glycol metabolism in overdose.
To report a case of D-lactic acid acidosis owing to massive oral ingestion of propylene glycol. ⋯ Ingestion of massive doses of propylene glycol, previously not reported as a cause of D-lactic acidosis, should be added to the differential diagnosis of this rare condition.

Relative toxicity of selective serotonin reuptake inhibitors (SSRIs) in overdose.
Selective serotonin reuptake inhibitors (SSRIs) have increasingly replaced tricyclic antidepressants (TCAs) in the treatment of depression. They appear to be safer in overdose, but there is little information on their spectrum of toxicity in overdose, or relative toxicity of each agent. ⋯ This study shows SSRIs are relatively safe in overdose despite serotonin syndrome being common. The exception was citalopram, which was significantly associated with QTc prolongation. We believe that cardiac monitoring should be considered in citalopram overdose, particularly with large ingestions and patients with associated cardiac disease.

Hexafluorine vs. standard decontamination to reduce systemic toxicity after dermal exposure to hydrofluoric acid.
Dermal exposure to hydrofluoric acid (HF) may cause severe burns and systemic toxicity. Hexafluorine (Prevor, France) is a product marketed as an emergency decontamination fluid for HF skin and eye exposures. Documentation concerning Hexafluorine is scanty, and a recent study indicates that its ability to reduce HF burns is at most equal to that of water. ⋯ In this experimental study, decontamination with Hexafluorine was not more effective than water rinsing in reducing electrolyte disturbances caused by dermal exposure to hydrofluoric acid.
