Case ReportsHemodialysis clearance of glyphosate following a life-threatening ingestion of glyphosate-surfactant herbicide.
Ingestion of glyphosate-surfactant herbicides (GlySH) can result in acute kidney injury, electrolyte abnormalities, acidosis, cardiovascular collapse, and death. In severe toxicity, the use of hemodialysis is reported, but largely unsupported by kinetic analysis. We report the dialysis clearance of glyphosate following a suicidal ingestion of a glyphosate-containing herbicide. ⋯ We demonstrate the successful clearance of glyphosate using hemodialysis, with corresponding clinical improvement in a patient with several poor prognostic factors (advanced age, large volume ingested, and impaired consciousness). The effects of hemodialysis on the surfactant compound are unknown. Hemodialysis can be considered when severe acidosis and acute kidney injury complicate ingestion of glyphosate-containing products.

Observational StudyMirtazapine overdose is unlikely to cause major toxicity.
There is limited information on mirtazapine overdose, but cases of severe effects (seizures, serotonin toxicity and coma) have been reported. We aimed to investigate the clinical effects and complications of mirtazapine overdose. ⋯ Mirtazapine appears to be relatively benign in overdose, associated with tachycardia, mild hypertension and mild CNS depression not requiring intervention.

Drugs and other chemicals involved in fatal poisoning in England and Wales during 2000 – 2011.
Fatal poisoning data can reveal trends in the poisons encountered, which can help guide prescribing practices and product safety and other legislation, and more recently has helped to monitor the use of emerging drugs of abuse ( ‘ legal highs ’ ). ⋯ Alterations in the availability of paracetamol and of prescription drugs such as dextropropoxyphene and dosulepin have not been accompanied by decreases in the number of deaths from poisoning. Despite intense media and other interest, the annual number of deaths (250 – 300) involving ‘ recreational ’ drugs remains small in relation to the 1000 or so deaths a year from diamorphine and/or methadone.

Intravenous lipid emulsion-augmented plasma exchange in a rabbit model of clomipramine toxicity; survival, but no sink.
Intravenous lipid emulsion (ILE) has been shown to ameliorate toxicity from lipophilic xenobiotics, attributed in part through sequestration to circulating lipid droplets (sink). We postulated additional benefit with plasma exchange therapy undertaken subsequent to lipid injection, hypothesising enhanced blood carriage of lipophilic toxin to increase yield when combined with an extracorporeal method of elimination. ⋯ Infusion of lipid emulsion resulted in greater survival in this rabbit model of intravenous clomipramine toxicity. Plasma exchange performed in conjunction with administration of lipid emulsion failed to result in significant extracorporeal clomipramine elimination. Intravascular lipid sequestration of clomipramine appears an inadequate sole explanation for the beneficial effects of lipid emulsion.

2012 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 30th Annual Report.
This is the 30(th) Annual Report of the American Association of Poison Control Centers' (AAPCC) National Poison Data System (NPDS). As of July 1, 2012, 57 of the nation's poison centers (PCs) uploaded case data automatically to NPDS. The upload interval was 7.58 [6.30, 11.22] (median [25%, 75%]) min, creating a near real-time national exposure and information database and surveillance system. ⋯ These data support the continued value of PC expertise and need for specialized medical toxicology information to manage the more severe exposures, despite a decrease in calls involving less severe exposures. Unintentional and intentional exposures continue to be a significant cause of morbidity and mortality in the US. The near real-time, always current status of NPDS represents a national public health resource to collect and monitor US exposure cases and information calls. The continuing mission of NPDS is to provide a nationwide infrastructure for public health surveillance for all types of exposures, public health event identification, resilience response, and situational awareness tracking. NPDS is a model system for the nation and global public health.
