Laundry detergent pod (LDP) exposures in children have resulted in several referrals to the emergency department. Signs and symptoms can include gastrointestinal symptoms (vomiting, drooling), neurological symptoms (depressed sensorium), or metabolic changes (lactic acidosis). There is limited literature on esophageal injury following LDP ingestions. ⋯ Our case series demonstrates it is hard to predict esophageal injury based on signs and symptoms. Based on a literature review, long-term esophageal stricture is unlikely, but if gastrointestinal symptoms persist, it is reasonable to evaluate with an upper endoscopy. Larger studies are needed.

Those medical providers deployed to remote countries and tasked with caring for military personnel must diagnose and treat diseases and nonbattle injuries that result from exposures rarely seen in developed countries. Military providers must also function with limited resources and a lack of access to physician specialists, to include medical toxicologists. There have been limited published approaches to addressing this clinical gap for medical toxicology. ⋯ The most frequent consultations for the military telemedicine consultation service were for direct patient cases, specifically snake envenomation management and accidental chemical exposures. Our results may be used to educate physicians prior to military deployment or international humanitarian efforts and to create toxicology clinical guidelines for remote locations. Expansion of the current military teleconsultation program capabilities to include video teleconsultation may improve the effectiveness of military medical toxicology teleconsultation.

The use of intravenous lipid emulsion (ILE) as an antidote has prompted significant academic and clinical interest. Between August 2009 and August 2012, data from cases of ILE use in intoxicated patients in different hospitals on different continents were voluntarily entered into a registry based on the world wide web (www.lipidregistry.org). Here, we report data from this project. ⋯ In this series of cases reported to the registry, improvements were seen for GCS in patients with central nervous system toxicity and in systolic blood pressure in shocked patients over a short time frame after the injection of ILE. Few adverse effects were recorded. Clinical trials and the reporting of drug concentrations after ILE use are necessary to further elucidate the role of ILE in clinical toxicology.

Review Comparative Study
Comparison of current recommended regimens of atropinization in organophosphate poisoning.
Atropine is the mainstay of therapy in organophosphate (OP) toxicity, though research and consensus on dosing is lacking. In 2004, as reported by Eddleston et al. (J Toxicol Clin Toxicol 42(6):865-75, 2004), they noted variation in recommended regimens. We assessed revisions of original references, additional citations, and electronic sources to determine the current variability in atropine dosing recommendations. ⋯ In 2004, Eddleston et al. called for an evidence-based guideline for the treatment of OP poisoning that could be disseminated worldwide. Many current recommendations can adequately treat patients within 1 h. While the WHO recommendations remain slow to treat patients with OP poisoning, other authorities are close to a consensus on rapid atropinization.

Dabigatran, an oral direct thrombin inhibitor, is FDA approved for the prevention of stroke in patients with nonvalvular atrial fibrillation. No agent exists for the reversal of dabigatran-related major bleeding. Prothrombin complex concentrate (PCC) has been studied in reversal but was not shown to affect the surrogate markers of bleeding such as the thrombin time, ecarin clotting time, or activated partial thromboplastin time (aPTT). Recombinant factor VIIa (rFVIIa) may provide benefit in patients with life-threatening or major bleeding; however, it has not been studied in dabigatran-related bleeding. PCC and rFVIIa are agents utilized at our institution for major bleeding in patients receiving anticoagulant therapy. Due to the high cost and thrombogenic risk of both rVIIa and PCC and lack of a clear reversal strategy, we reviewed the management of all reported cases of dabigatran-related bleeding. ⋯ Reversal strategies for dabigatran-related bleeding events at our institution are highly variable. Intracranial hemorrhage in patients on dabigatran was associated with 43 % mortality. Patients with severe dabigatran-related bleeding may benefit from a standardized approach to treatment.
