The idea of doing a research or scholarly project can be very daunting, however, the satisfaction of seeing a project to its completion is very rewarding. In this article, we provide medical students with guidance on whether they should take on a research or scholarly project during medical school, and how to get started, publish, and then present their project. We also highlight how such a project can benefit an applicant applying for residency training.

Myocarditis is a rare sequelae of acute myeloid leukemia (AML) and typically presents after the initial diagnosis of AML has been made. ⋯ We present the case of a 37-year-old female who came to the emergency department with chest pain, ST elevations on electrocardiogram, and a positive point-of-care troponin. She was brought emergently to the cardiac catheterization laboratory. After a negative catheterization, blasts were noted on the complete blood count, ultimately leading to the diagnosis of AML, with myopericarditis as the presenting manifestation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the need for emergency physicians to consider a broad differential for chest pain, especially in those who do not fit into the prototypical patient with acute coronary syndrome.

Case Reports
Varicella Zoster Virus Meningoencephalitis With an Atypical Presentation of Chest Pain, Impaired Memory, and Seizure.
Neurologic complications of varicella zoster virus (VZV) reactivation can be associated with considerable mortality and morbidity. Aseptic meningitis associated with VZV infection is rare, occurring in 0.5% of immunocompetent individuals. One third of VZV-related neurologic disease occurs without the classic herpes zoster exanthema, making early recognition more difficult. ⋯ A 60-year-old man presented to the emergency department with chest pain and impaired memory that he attributed to a transient ischemic attack as suggested by an urgent care facility 1 day earlier. He suffered a seizure while in the emergency department and was admitted to the intensive care unit. A computed tomography scan of his head and a magnetic resonance imaging scan were both negative for acute findings. An abnormal electroencephalogram consistent with an encephalopathy together with his new-onset seizure triggered a lumbar puncture that was positive for VZV. He was placed on acyclovir and was discharged from the hospital 5 days after admission. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The typical presentation of a VZV central nervous system infection occurs with a sudden onset of fever, headache, nuchal rigidity, and focal neurologic signs. Our patient's recent impaired memory and subsequent seizure were likely manifestations of the developing VZV meningoencephalitis, while his chest pain may have correlated with subsequent development of a vesicular rash. Seizures are encountered in 11% of patients with VZV central nervous system infection, and VZV has recently been associated with cerebral vasculopathy. Awareness of alternative presentations for herpes zoster and meningitis is important in cases without classic symptoms to enable diagnosis and prevent delays in treatment.

Caffeine (1,3,7-trimethylxanthine) is a naturally occurring compound found in plants and is the most utilized drug in the world. An estimated 89% of U.S. citizens and 80% of people worldwide consume caffeine on a regular basis. The prevalence of caffeine supplementation by individuals has been increasing in body-weight regulation (e.g., weight loss, body building). When used in excessive amounts it can precipitate serious health consequences, including death. Given this, and the ease of accessibility, caffeine has been seen in intentional overdose. However, suicide attempts via caffeine overdose are rare. In 2017, the American Association of Poison Control Centers reported 3765 cases of caffeine overdose, of which 650 were intentional and none resulted in death from caffeine alone. An ingestion of 5 g (80-100 mg/kg) is likely to prove fatal. ⋯ We present the case of a suicide attempt via caffeine with a reported 20-g overdose, which would be an estimated blood caffeine level of 427.1 mg/L. The patient was given activated charcoal and treated for symptomatic tachycardia and diaphoresis. He was ultimately evaluated by Psychiatry and was discharged home with no adverse outcomes from his intentional overdose. We also examine the physiology of the potential adverse effects of caffeine use and the current literature related to caffeine overdoses. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Caffeine is consumed by billions of individuals globally. It is rarely associated with death, but can cause a variety of adverse effects including tachydysrhythmias, hypokalemia, seizures, and rhabdomyolysis. Caffeine overdoses should be treated immediately with activated charcoal if within the appropriate timeframe of 1-2 h post-ingestion, and special attention should be given to the cardiovascular effects of caffeine, as tachydysrhythmias may prove fatal.
