Whilst it is known that abdominal pain is a common symptom in patients with acetaminophen overdose, its association with severity of liver injury has not been clearly defined. This study investigates the association between the symptom of abdominal pain on presentation to hospital and the degree of liver injury post-acetaminophen overdose. ⋯ The presence of abdominal pain after acetaminophen overdose was not predictive of the development of liver injury in patients receiving acetylcysteine treatment. Further prospective studies are required to confirm this finding. The data that support the findings of this study are available on request from the corresponding author. The data are not publicly available due to privacy or ethical restrictions.

Olanzapine/Samidorphan (Lybalvi®) is a novel oral agent for the treatment of schizophrenia and bipolar I disorder. It was designed to reduce weight gain associated with olanzapine. Samidorphan is an analog of naltrexone, initially intended to treat substance use disorders by antagonizing mu, delta, and kappa opioid receptors. ⋯ We present the case of a 36-year-old who took their first dose of olanzapine/samidorphan shortly before calling for emergency services. The patient took diphenhydramine and an epinephrine autoinjector for what they thought was an allergic reaction but continued to have symptoms. EMS reported involuntary muscle movements thought to be due to dystonia from olanzapine. In the ED, they experienced generalized muscle spasms lasting for several seconds and diaphoresis. Initially, the staff treated for a presumed dystonic reaction to olanzapine and administered diphenhydramine 25 mg IV, diazepam 2 mg IV, midazolam 5 mg IV, and benztropine 1 mg IV without improvement. It was later determined that the patient took 16 mg of buprenorphine SL daily. With this information, precipitated opioid withdrawal was felt to be the likely cause of symptoms. The patient received 16 mg of buprenorphine for an initial Clinical Opiate Withdrawal Scale (COWS) score of 11 with repeat COWS of 6. Why should an emergency physician be aware of this? Initiating olanzapine/samidorphan in the setting of chronic opioid therapy may result in precipitated opioid withdrawal. Additional SL buprenorphine may be a reasonable treatment modality.

Case Reports
Obstructive myocardial infarction with normal automated ECG interpretation: A case report.
Emergency Medicine physicians experience a significant number of interruptions throughout their work day. One common cause of interruptions is the immediate interpretation of triage electrocardiograms (ECGs). Recent studies have suggested that ECGs interpreted as normal via automated analysis by the ECG machine rarely require urgent cardiac intervention and suggested that providers may not have to be interrupted to interpret these "normal" ECGs. We describe the case of a patient who presented to the Emergency Department (ED) with chest pain and an ECG interpreted as normal by an automated reading from the ECG machine, despite having acute coronary syndrome requiring emergent intervention.
