- Purpose: The purpose of this study is to evaluate the effectiveness and adverse effect of fomepizole in the management of acute ethylene glycol or methanol poisoning in children. Methods: Databases such as PubMed, Embase, Cochrane library, and KoreaMed were searched using terms related to fomepizole, ethylene glycol, methanol and pediatric. All studies, regardless of study design, reporting effectiveness or safety endpoints in children were included. Reference citations from identified publications were reviewed. Only reports written in English or Korean languages were included. The reference search was performed by two authors. Results: Twenty-two relevant literatures were finally included. They were one narrative review, 4 retrospective case series, and 17 case reports (19 cases). Case reports were classified as 5 fomepizole only, 8 fomepizole with other therapies, and 6 no fomepizole. All patients from the literatures were fully recovered without long term sequelae. Adverse effects of fomepizole were reported including anaphylaxis, thrombophlebitis and nystagmus. Conclusion: There are insufficient literatures regarding fomepizole treatment in children with ethylene glycol or methanol poisoning. The benefits or harms are not clearly established based on the clinical evidences. More prospective comparative studies are required in the future.

- Purpose: Extracorporeal life support (ECLS) is a term used to describe a number of modalities including extracorporeal membrane oxygenation (ECMO) to support cardiac and/or pulmonary systems. The purpose of this study is to review the available evidence regarding the effect of ECLS in patients with acute poisoning. Methods: Electronic literature searches with PubMed, Embase, Cochrane library, and KoreaMed were conducted for identification of relevant studies addressing ECLS in treatment of acute poisoning. The literature search was conducted by two investigators in March, 2016 with publication language restricted to English and Korean. The toxic substance, technique of ECLS, and final outcome of each case were analyzed. Results: The final analysis included 64 articles including 55 case reports. There were no articles classified according to a high level of evidence such as randomized trial and prospective cohort study. ECLS treatment was used in the management of patients poisoned with 36 unique substances. Venovenous ECMO was performed in 4 cases. Among the reported cases, 10 patients died despite treatment with ECLS. Conclusion: Evidence supporting ECLS for patients with acute poisoning is inadequate. However, many case reports suggest that early consideration of ECLS in poisoned patients with refractory cardiac arrest or hemodynamic compromise refractory to standard therapies may be beneficial.

- Purpose: The purpose of this study is to evaluate the effectiveness and the adverse events of high dose insulin/euglycemia therapy in acute calcium channel blocker (CCB) poisoning. Methods: We developed a systematic search strategy and applied it to 4 electronic reference databases. We searched medical journals as well as the bibliographies of relevant articles. All forms of literature relevant to human use of high dose insulin for acute CCB poisoning were included. The literature search was conducted by two investigators in August, 2015 with publication language restricted to English and Korean. Case reports were divided between CCB overdose alone and multi-drug overdose including CCB. The effect and adverse event of high dose insulin and clinical outcome of each case were analyzed. Results: Among 55 searched studies, 20 studies were included. A prospective study, a retrospective study, a systematic review study, and 17 case reports were identified. Case reports consisted of 11 CCB alone and 12 multidrug overdose cases including CCB. Although most cases described significant clinical improvements, one of them showed no beneficial effect. Several adverse events including hypoglycemia and hypokalemia were reported. No significant sequalae from adverse events was reported. Conclusion: Although there were many case reports demonstrating successful use of high dose insulin for CCB poisoning, the effect cannot be estimated due to a possibility of publication bias. Therefore, high dose insulin/euglycemia therapy might be considered adjunctive therapy in cases of CCB intoxication refractory for standard therapy.

- Purpose: The purpose of this study was to evaluate the usefulness of intravenous lipid emulsion as well as adverse events in acute poisoning patients. Methods: Literature was accessed through PubMed, EMBASE, Cochrane library, Web of science, and KoreaMed. All forms of literatures relevant to human use of intravenous lipid emulsion for acute poisoning were included. Cases reports or letters without description of clinical outcomes for each case were excluded. The literature search was conducted by two investigators in March, 2015, with publication language restricted to English and Korean. The effect, onset time, and adverse event of lipid emulsion and final outcome of each case were analyzed. Results: Eighty-one published articles were included, excluding articles whose title and abstract were not relevant to this study. No articles were classified as high level of evidence. Sixty-eight case reports were identified, consisting of 25 local anesthetics and 43 other drugs, such as tricyclic antidepressants and calcium channel blockers. Although most cases described significant clinical improvements, some of them showed no beneficial effect or worsening of clinical course. Several adverse events including hyperamylasemia and laboratory interference were reported. Conclusion: Although there were many case reports illustrating successful use of lipid for various drug poisonings, the effect cannot be estimated due to significant possibility of publication bias. Therefore, lipids might be considered in severe hemodynamic instability resulting from lipophilic drug poisoning, however further studies should follow to establish the use of lipid as the standard of care.

- Purpose: The purpose of this study is to review the evidence comparing the efficacy and safety between L-carnitine and extracorporeal elimination therapy in the management of acute valproic acid L-carnitine vs Extracorporeal Elimination for Acute Valproic acid Intoxication Methods: PubMed, Embase, Cochrane library, Web of Science, KoreaMed, KMbase, and KISS were searched, using the terms carnitine and valproic acid. All studies, regardless of design, reporting efficacy or safety endpoints were included. Reference citations from identified publications were reviewed. Both English and Korean languages were included. Two authors extracted primary data elements including poisoning severity, presenting features, clinical management, and outcomes. Results: Thirty two articles including 33 cases were identified. Poisoning severity was classified as 3 mild, 11 moderate, and 19 severe cases. Nine cases were treated with L-carnitine while 24 cases received extracorporeal therapy without L-carnitine. All patients except one expired patient treated with hemodialysis recovered clinically and no adverse effects were noted. A case report comparing two patients who ingested the same amount of valproic acid showed increased ICU stay (3 vs 11 days) in case of delayed extracorporeal therapy. Conclusion: Published evidence comparing L-carnitine with extracorporeal therapy is limited. Based on the available evidence, it is reasonable to consider L-carnitine for patients with acute valproic acid overdose. In case of severe poisoning, extracorporeal therapy would also be considered in the early phase of treatment.

- Purpose: The purpose of this systematic review was to evaluate the evidence regarding injury and poisoning associated with the clinical mercury thermometer. Methods: Electronic literature searches were conducted for identification of relevant studies and case reports of injury and poisoning associated with the clinical mercury thermometer. The search outcomes were limited to literature with English and Korean languages published from 1966. Studies related to occupational mercury exposure, or mercury exposure from sphygmomanometer, barometer, and fluorescent light were excluded. Results: A total of 60 reports, including 59 case reports, were finally included. Of those, nine cases pertained to an intact thermometer as a foreign body, 25 injuries were related to a thermometer, and 26 cases involved exposures to mercury from a broken thermometer. Case reports were classified according to severity into 16 mild, 41 moderate, and two severe cases. Two cases of mortality were reported, one was deliberate intravenous injection of mercury and the other was acute vapor inhalation of mercury from broken thermometers. Conclusion: Findings of this systematic review suggested that the mercury thermometer could cause various forms of poisoning and injury. In particular, inhalation of mercury vapor from a broken thermometer can lead to systemic toxicity requiring chelating therapy.

- We report on a patient who developed acute hepatic failure despite intravenous N-acetyl cysteine therapy who was treated with the Molecular Adsorbents Recirculating System (MARS). She presented 20 hours after the ingestion of 13 g of acetaminophen. The MARS is based on albumin dialysis principle which can be applied for patients with acute poisoning from drugs that have high protein-binding capacity because of its ability to selectively remove from circulation protein-bound toxins. The clinical toxicologist should be consider this technology when treating patients with hepatic failure following acetaminophen poisoning.
