A retrospective review of 911 calls to a regional poison control center.

Background: There is little data as to what extent national Emergency Medical Services (EMS; 911) utilize poison control centers (PCCs). A review of data from our PCC was done to better understand this relationship and to identify potential improvements in patient care and health care savings.

Methods: Retrospective chart review of a single PCC to identify calls originating from 911 sources over a 4-year study period (1/1/08-12/31/11).

Massive Atenolol, Lisinopril, and Chlorthalidone Overdose Treated with Endoscopic Decontamination, Hemodialysis, Impella Percutaneous Left Ventricular Assist Device, and ECMO.

Background: Overdose of cardiovascular medications is increasingly associated with morbidity and mortality. We present a case of substantial atenolol, chlorthalidone, and lisinopril overdose treated by multiple modalities with an excellent outcome.

Conclusion: Aggressive medical intervention did not provide sufficient hemodynamic stability in this patient with refractory cardiogenic and distributive shock.

Serotonin syndrome associated with metaxalone overdose.

Introduction: Serotonin syndrome is a potentially life-threatening entity associated with pro-serotonergic medications in therapeutic use, in overdose, or when co-administered with other drugs. A broad range of drugs and drug combinations have been associated with serotonin syndrome. Metaxalone overdose associated with serotonin syndrome has not been previously reported.

A case of neurotoxicity following envenomation by the Sidewinder rattlesnake, Crotalus cerastes.

Introduction: North American rattlesnake envenomations typically result in local tissue injury and hematologic derangements. Neurotoxicity is uncommon but when present often manifests as fasciculations and paresthesias. Neurotoxicity following Sidewinder (Crotalus cerastes) envenomation has not been previously reported.

Hemodialysis treatment of monomorphic ventricular tachycardia associated with chronic lithium toxicity.

Introduction: A patient with chronic lithium toxicity developed a life-threatening ventricular arrhythmia that resolved during removal of lithium by hemodialysis. Chronic lithium toxicity commonly results from diminished elimination and can produce neurotoxicity. Cardiovascular complications have been reported and generally affect the sinoatrial node and produce bradyarrhythmias.

Complications following antidotal use of intravenous lipid emulsion therapy.

The primary objective is to identify and describe the complications associated with the use of intravenous lipid emulsion (ILE) therapy as an antidote for lipophilic drug toxicity. This study is a retrospective chart review of patients treated with ILE at two academic medical centers between 2005 and 2012. Based on previously reported complications, we hypothesized that pancreatitis, ARDS, and lipemia-induced laboratory interference might occur.

Recurrent seizures and serotonin syndrome following "2C-I" ingestion.

The phenethylamines, including 2, 5 dimethoxy-4-iodophenethylamine, commonly referred to as 2C-I, have recently emerged as a new class of designer drugs. Cases of toxicity from these drugs are not well described in the literature. This case report describes a 19 year-old male who insufflated 2C-I.
