Case ReportsLead toxicity and endoscopic removal of ingested firearm cartridges.
Lead toxicity from the ingestion of a lead foreign body has been described in several case reports. Management of ingested live ammunition presents its own challenges due to the risk of accidental discharge. A safe and effective method of retrieving a live cartridge must be considered. ⋯ These cases illustrate a diagnostic dilemma in both the diagnosis of lead toxicity and the removal of live ammunition from the stomach.

Case ReportsMetformin overdose-induced hypoglycemia in the absence of other antidiabetic drugs.
Lactic acidosis is a well-recognized consequence of metformin. Hypoglycemia has been reported previously in metformin overdose, but the presence of other co-ingestions (e.g., a sulfonylurea) was not definitively excluded. ⋯ Metformin overdose can cause severe hypoglycemia in the absence of other antidiabetic drugs. Potential mechanisms of metformin-induced hypoglycemia include decreased hepatic glucose production, decreased glucose absorption, and poor oral intake.

ReviewExtracorporeal membrane oxygenation in the treatment of poisoned patients.
Although extracorporeal membrane oxygenation (ECMO) was used in many patients following its introduction in 1972, most hospitals had abandoned this experimental treatment for adult patients. Recently, improvements in the ECMO circuitry rendered it more biocompatible. The surprisingly low mortality in patients with severe acute respiratory distress syndrome who were treated with ECMO in the influenza A/H1N1 pandemic of 2009 resurrected interest in ECMO in many intensive care units around the world. ⋯ In the last decade, ECMO equipment has improved considerably, rendering it more biocompatible, and it has been used more frequently as an assist device for patients needing oxygenation as well as circulatory support. ECMO is considered a good salvage therapy for patients who are severely poisoned with ARDS or refractory circulatory shock.

Multicenter StudyA multicenter retrospective survey on a suicide trend using hydrogen sulfide in Japan.
In Japan, suicide by inhaling hydrogen sulfide (H2S) by mixing commercial products escalated into a nationwide trend in April 2008. ⋯ Mortality (58%) among patients who attempted H2S suicide was very high, likely resulting from inhaling high concentrations of H2S after mixing commercial products in a sealed and confined space.

Mulga snake (Pseudechis australis) envenoming: a spectrum of myotoxicity, anticoagulant coagulopathy, haemolysis and the role of early antivenom therapy - Australian Snakebite Project (ASP-19).
Mulga snakes (Pseudechis australis) are venomous snakes with a wide distribution in Australia. Objective. The objective of this study was to describe mulga snake envenoming and the response of envenoming to antivenom therapy. ⋯ Mulga snake envenoming is characterised by myotoxicity, anticoagulant coagulopathy and haemolysis, and has a spectrum of toxicity that is venom dose dependant. This study supports a dose of one vial of antivenom, given as soon as a systemic envenoming is identified, rather than waiting for the development of myotoxicity.
