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.

Case ReportsRefractory hypotension due to Rogaine® (minoxidil) ingestion managed with midodrine.
Minoxidil (Rogaine®) is a direct vasodilator that can cause significant toxicity when ingested. We report a case of ingestion of topical minoxidil [Rogaine® (Johnson & Johnson Healthcare Products, Division of McNeil-PPC, Inc)] resulting in refractory hypotension that was successfully managed with the oral α (1) agonist midodrine. ⋯ Midodrine may serve as an additional option to treat toxicant induced hypotension.

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.
