Respiratory Syncytial Virus (RSV) has been recognized for over half a century as a cause of morbidity in infants and children. Over the past 20years, data has emerged linking RSV as a cause of illness in adults resulting in 177,000 annual hospitalizations and up to 14,000 deaths among older adults. ⋯ Adults can harbor RSV as this can lead to significant mobility and mortality, especially in individuals who are over the age of 60. RSV is not being considered in the DDx diagnosis, and this was especially surprising in the transplant/immunocompromised subgroups. Given antiviral treatment options, educational efforts should be undertaken to raise awareness of RSV in adults.

Sick sinus syndrome is a disorder of sinus node function characterized by various dysrhythmias such as sinus bradycardia or pause, paroxysmal regular or irregular atrial tachycardia, tachycardiabradycardia attacks or atrial fibrillation with slow ventricular response. Ventricular asystole with preserved atrial electrical activity is a rarely seen presenting rhythm in the ED and an extremely rare cause of syncope. A 67-year-old male having a syncope attack was admitted to the emergency department. ⋯ A dual-chamber pacemaker was placed, and he was discharged after 2days of in patient follow-up. His symptoms have not recurred after placement of the pacemaker device. When sudden changes in vital parameters and/or consciousness develop during observation of a patient with sick sinus syndrome, although it is not a common circumstance, accompanying high degree atrioventricular block and simultaneous ventricular asystole should be considered, and cardiopulmonary resuscitation should be initiated immediately because cardiopulmonary arrest is inevitable when ventricular asystole develops even if the atrial electrical activity is maintained.

Case Reports
Pressor support during a Jarisch Herxheimer reaction after initiation of treatment for Weil's disease.
We present a case of Weil's disease complicated by a Jarisch-Herxheimer reaction (JHR) after initiation of antibiotics while in the emergency department requiring invasive monitoring and vasopressor support. The case is followed by a brief review of the JHR which is rarely observed with treatment of leptospirosis. A healthy 28-year-old female who recently returned from the Caribbean presented to the emergency department with flu-like symptoms. ⋯ Although rarely encountered and not well reported throughout the literature, initiation of antibiotics can cause a JHR reaction given that Leptospira interrogans is a spirochete. This JHR may be self-limited and of short duration, or it can be prolonged and severe, requiring invasive therapies such as central line placement for vasopressor support and intubation. It is suggested that patients started on antibiotics for leptospirosis/Weil's disease should be monitored in the emergency department for a short duration prior to discharge or transfer to a regular medical floor for observation given the possibility for decompensation.
