Case ReportsIntravenous paracetamol toxicity in a malnourished child.
We present a case of intravenous (IV) paracetamol overdose in a nutritionally malnourished child during hospital admission. A ten-fold IV paracetamol dosing error ocurred, with delayed recognition and treatment resulting in transient hepatotoxicity, with a peak alanine transaminase (ALT) of 1378 IU/L in a 3-year-old child. Our case suggests that hepatotoxicity may occur for lower doses of IV paracetamol compared to oral ingestion, especially in the malnourished, and that a dose less than 150 mg/kg of IV paracetamol should be used to define treatment following overdose in a child with potential nutritional deficiencies.

Examination of adverse events following black widow antivenom use in California.
Following widow spider (Latrodectus sp.) envenomation, local pain, erythema, abdominal pain, rigidity, hypertension, and diaphoresis can be seen. While an effective specific antivenom (AV) is available, its use is limited due to concern of possible severe allergic reaction. We performed the current study to determine rate of adverse effects and the efficacy of AV in patients treated for widow spider envenomation. ⋯ Our results suggest that Black Widow Spider Antivenin® (Merck) administration is relatively safe with mild to moderate adverse effects seen in only a small percentage of patients. There were no deaths, or severe allergic reactions identified. The retrospective use of poison control system data is a limitation of our study. Further prospective studies are needed to validate our findings and elucidate the full safety profile on this antivenom.

2010 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 28th Annual Report.
This is the 28th Annual Report of the American Association of Poison Control Centers' (AAPCC) National Poison Data System (NPDS). All US poison centers upload case data automatically with a median time interval of 19.0 [11.9, 40.6] (median [25%, 75%]) minutes, creating a near real-time national exposure and information database and surveillance system. ⋯ These data support the continued value of poison center expertise and need for specialized medical toxicology information to manage the more severe exposures, despite a decrease in calls involving less severe exposures. Unintentional and intentional exposures continue to be a significant cause of morbidity and mortality in the US. The near real-time, always current status of NPDS represents a national public health resource to collect and monitor US exposure cases and information calls. The continuing mission of NPDS is to provide a nationwide infrastructure for public health surveillance for all types of exposures, public health event identification, resilience response and situational awareness tracking. NPDS is a model system for the nation and global public health.

ReviewMethanol and ethylene glycol acute poisonings - predictors of mortality.
Methanol and ethylene glycol cause significant mortality post-ingestion. Predicting prognosis based on the biomarkers osmolal gap, anion gap and pH is beneficial. ⋯ Post-methanol ingestion a large osmolal gap, anion gap and low pH (<7.22) were associated with increased mortality; and pH has the highest predictive value. Post-ethylene glycol ingestion, both osmolal gap and anion gap were associated with increased mortality.

Surfactant volume is an essential element in human toxicity in acute glyphosate herbicide intoxication.
Glyphosate, one of the most commonly used herbicides worldwide, has been considered as minimally toxic to humans. However, clinical toxicologists occasionally encounter cases of severe systemic toxicity. The purpose of this study was to determine the effect of glyphosate-surfactants ("glyphosate-surfactant toxicity") in patients with acute glyphosate intoxication. ⋯ Our results indicate that treatment of patients with acute glyphosate herbicide intoxication should take into account the volume and not the type of surfactants in herbicide formulations.
