Ethylene glycol is a widely used chemical that is capable of causing significant injury if ingested. Treatment for ethylene glycol poisoning typically includes basic supportive care, alcohol dehydrogenase inhibition, and hemodialysis. Recent data have suggested that hemodialysis may not be necessary for cases of ethylene glycol poisoning that can be treated with fomepizole as blocking therapy before acidosis or renal dysfunction develops. ⋯ This report describes the case of a patient who presented soon after a massive ingestion of ethylene glycol with very high serum concentrations. He was successfully treated using fomepizole and basic supportive care. Our patient developed neither renal insufficiency nor metabolic acidosis. His concomitant ethanol consumption, early presentation, and treatment likely contributed to his favorable outcome. This case report underscores the effectiveness of supportive care and fomepizole in the treatment of ethylene glycol poisoning.

Profound metabolic acidosis in critically ill adults sometimes remains unexplained despite extensive evaluation. ⋯ In critically ill adults with unexplained metabolic acidosis, 5-Oxoproline should be considered in the differential.

Ibuprofen is a commonly used non-steroidal anti-inflammatory drug. While the vast majority of exposures to the drug do not result in significant morbidity, we are reporting 2 fatalities that resulted from massive ibuprofen ingestion. CASE 1: A 17-year-old girl presented to the emergency department (ED) following an ibuprofen overdose; she was unresponsive with a metabolic acidosis and hypothermic. Her serum ibuprofen concentration was 352 microg/mL: the therapeutic range is 10-50 microg/mL. Despite intensive supportive care and continuous veno-venous hemofiltration, she expired. CASE 2: A 49-year-old man presents to the ED with a history of divalproex sodium and ibuprofen ingestion. He was unresponsive, hypotensive, and had a significant metabolic acidosis. His serum ibuprofen concentration was 260 microg/mL and serum valproate concentration was 560 microg/mL: the therapeutic range is 50-100 microg/mL. In spite of supportive care and hemodialysis, he expired. ⋯ We will describe 2 cases of ibuprofen overdose characterized by cardiovascular collapse, acidosis, and hypothermia despite the use of vasopressors and renal replacement therapy. Although rarely reported, massive ibuprofen overdose may result in refractory multisystem organ failure and death.

Case Reports
Acute clenbuterol overdose resulting in supraventricular tachycardia and atrial fibrillation.
We are presenting a case illustrating the complex metabolic and rhythm disturbances associated with acute clenbuterol intoxication. ⋯ Considering the significant number of body-building enthusiasts, physicians will continue to encounter clenbuterol abuse in their clinical practices.

Antiarrhythmics can have devastating effects in cardiotoxic poisonings. Amiodarone is recommended for treatment of wide complex tachycardia, but its hemodynamic effects in wide complex tachycardia induced by tricyclic antidepressant poisoning are unknown. The objective of this study was to compare the effects of sodium bicarbonate, amiodarone, and normal saline in treating wide complex tachycardia secondary to nortriptyline poisoning. ⋯ In this model of nortriptyline poisoning, the administration of amiodarone to correct wide complex tachycardia did not have a harmful effect.
