Naloxone is a frequently utilized and effective treatment to reverse the life-threatening effects of illicit opioid intoxication. Excessive naloxone dosing in these circumstances, however, may lead to naloxone-precipitated opioid withdrawal in individuals with opioid dependence. Buprenorphine, a partial mu-opioid agonist, is increasingly utilized in the Emergency Department (ED) for the treatment of opioid withdrawal syndrome but little is known regarding its utility in cases of naloxone-precipitated opioid withdrawal. ⋯ The patient was subsequently discharged to a treatment facility for opioid use disorder. This case highlights the potential of buprenorphine as a treatment modality for acute naloxone-precipitated opioid withdrawal. Due to the risks of worsening or sustained buprenorphine-precipitated opioid withdrawal, further research is warranted to identify patients who may benefit from this therapy.

Caffeine is the most commonly used central nervous system stimulant. While it has a high LD50 (150-200 mg/kg), when ingested in significant quantity, caffeine can lead to severe and even lethal side effects. Manifestation of toxicity include tachyarrhythmias, seizures, and metabolic derangements which can eventually lead to cardiovascular collapse and death. ⋯ Initial pre-dialysis caffeine level was found to be 254 μg/ml. After treatment with two sessions of hemodialysis the patient's caffeine level decreased dramatically. We believe this is the first case report to demonstrate the success of preemptive hemodialysis, prior to cardiovascular collapse and/or renal failure, in a case of caffeine overdose and should be considered very early in patients presenting with recent toxic ingestion.

Emergency physicians frequently treat hyperemesis gravidarum and should be aware of possible complications. Wernicke encephalopathy secondary to thiamine deficiency should be considered in the differential diagnosis of acute encephalopathy in pregnant women. A seventeen-week pregnant 27-year-old woman presented to the Emergency Department with nausea, emesis, and right upper quadrant abdominal pain. ⋯ Emergency physicians frequently treat hyperemesis gravidarum. Nutritional status should be evaluated in patients who are unable to take neonatal vitamins. Awareness should exist of possible complications, including Wernicke encephalopathy secondary to thiamine deficiency.

Case Reports
Use of fomepizole, n-acetylcysteine, and hemodialysis for massive acetaminophen overdose.
Acetaminophen poisoning is the leading cause of liver transplantation within the United States, accounting for nearly 56,000 emergency department patient visits each year. Although n-acetylcysteine is commonly successful in preventing acetaminophen toxicity when given in a timely manner, reports do exist demonstrating n-acetylcysteine therapy failure, commonly in the setting of a massive ingestion. We present the use of a novel antidote cocktail of n-acetylcysteine, fomepizole, and hemodialysis to treat a massive acetaminophen ingestion. ⋯ The patient was diagnosed with severe acetaminophen poisoning and was promptly administered n-acetylcysteine. Due to the severity of the patient's ingestion and the concern for additional coingestants, the patient was also given fomepizole therapy and later underwent hemodialysis for more rapid toxin clearance. After a four-day stay in the hospital the patient was discharged to a mental-health facility with no signs of systemic injury.
