Aortic dissection (AD) is a life-threatening but uncommon and challenging diagnosis to make in the emergency department. Cardiac point-of-care ultrasound (POCUS) is often used to evaluate patients with chest pain and may be used to rapidly diagnose Stanford type A AD on the suprasternal notch view if there is the visualization of a dissection flap. In contrast, a diagnosis of type B AD on the suprasternal notch view is rare and has only been reported in one previous case report. We report the case of a patient who presented with chest pain and was accurately diagnosed with type B AD using the suprasternal notch view., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2019, Wang et al.)

Human herpesvirus 6 (HHV-6) is a double-stranded DNA virus part of the Herpesviridae family that colonizes nearly 100% of the human population. The virus is known to be the etiologic agent of roseola infantum, a self-limited disease in childhood and reactivation of the virus later in life is linked to potentially severe manifestations, including encephalitis, in immunosuppressed patients. It is rare in immunocompetent patients, but there have been several reports of encephalitis due to HHV-6 reactivation. We describe here a case of altered mental status and multi-organ failure in an immunocompetent woman, whose cerebrospinal fluid (CSF) was positive for HHV-6 DNA by polymerase chain reaction (PCR)., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2019, Wang et al.)
