Many medical toxicologists are interested in participating in a practice-based, multicenter research and toxicosurveillance network. In 2009, the American College of Medical Toxicology established the Toxicology Investigators Consortium (ToxIC). One facet of ToxIC is a registry that can be used for surveillance of new or old agents, assessment of treatment decisions, and the creation of new research questions. ⋯ Thirty-three toxicology practice sites, encompassing 56 hospitals and clinics, have entered data into the ToxIC Registry. During the first 14 months of data collection, 5,412 patients were entered. The experience thus far demonstrates that the creation of this registry is feasible and constitutes a potentially powerful toxicosurveillance and robust research tool.

Dabigatran (Pradaxa) is a competitive direct thrombin inhibitor approved by the US FDA for prevention of embolic stroke in patients with nonvalvular atrial fibrillation. Dabigatran has a pharmacokinetic profile that produces predictable anticoagulation responses, does not undergo CYP 450 metabolism, has few drug-drug and drug-food interactions, and does not require frequent laboratory monitoring of clotting parameters. Clinicians are rapidly prescribing this agent as a replacement for warfarin therapy. ⋯ Transfusion of FFP would not be expected to help control bleeding. Limited and mixed data exist for transfusion of factor VIIa and prothrombin complex concentrates; these therapies should be considered as well as dialysis, which will increase elimination in patients with life-threatening or closed-space bleeding due to dabigatran. We present an article that reviews the pharmacokinetics, clinical trial literature, and consensus guidelines regarding this novel oral anticoagulant.

The American College of Medical Toxicology Case Registry was established in 2010 as a method of identifying cases cared for by medical toxicologists at participating institutions. The Registry allows for the extraction of information from medical records making it the most robust multicenter database on chemical toxicities in existence. The current report is a summary of the data collected in 2010. ⋯ The Registry can identify and characterize patients who have sufficient toxicity to require a consultation by a medical toxicologist. Hypotheses for further investigation emerged from the data. The Registry appears to be a potentially powerful tool for toxicovigilance and research.

This study examines the relation between seizure and plasma tramadol concentration in patients with tramadol poisoning, as a novel centrally acting analgesic used for the treatment of mild to severe pain. All patients admitted with a history of tramadol overdose accompanied by unconsciousness or seizures referred to Baharloo Hospital Poison Center, Tehran, Iran from March 2008 to March 2009 were included. Demographic information, clinical findings, and blood tramadol concentrations were studied. ⋯ Most patients experienced just one seizure (76%). The tramadol-induced seizure is dose dependent. Although higher doses of tramadol was related to higher blood concentration, blood tramadol concentrations was not associated with seizure.
