cefotaxime and Hypotension

Prevotella species (i. e. P. intermedia, P. nigrescens, P. pallens, P. oris) are usually responsible for abscesses of head and neck spaces after dental procedures. P. intermedia - related infective endocarditis has never been reported.. A 22-year-old man, with a history of aortic valve replacement 6 years ago, presented with fever and persistent retrosternal chest pain. An empirical antibiotic therapy was started on (cefotaxime, 2gx3 - gentamicin, 5mg/kilo). Five blood cultures were positive at Prevotella Intermedia. Metronidazole was introduced (500mg X 3 by day).The oro-pharyngeal spaces were normal. The evolution was marked by a hypotension, a third degree atrio-ventricular block, and a rapidly growing aortic root abscess complicated this case of Prevotella Intermedia infective endocarditis (IE). Aortic valve redux surgery was performed at day 5 of admission. Post-operative course was unremarkable.. This first reported case of Prevotella Intermedia IE presented suggestive features of anaerobic IE as the patient developed both aortic-ring abscess, third degree atrio-ventricular block and hypotension.

The work-up and initial management of a critically ill neonate is challenging and anxiety provoking for the Emergency Physician. While sepsis and critical congenital heart disease represent a large proportion of neonates presenting to the Emergency Department (ED) in shock, there are several additional etiologies to consider. Underlying metabolic, endocrinologic, gastrointestinal, neurologic, and traumatic disorders must be considered in a critically ill infant. Several potential etiologies will present with nonspecific and overlapping signs and symptoms, and the diagnosis often is not evident at the time of ED assessment.. We present the case of a neonate in shock, with a variety of nonspecific signs and symptoms who was ultimately diagnosed with tachycardia-induced cardiomyopathy secondary to a resolved dysrhythmia. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the diagnostic and therapeutic approach to the critically ill neonate in the ED, and expands the differential diagnosis beyond sepsis and critical congenital heart disease. Knowledge of the potential life-threatening etiologies of shock in this population allows the Emergency Physician to appropriately test for, and empirically treat, several potential etiologies simultaneously. Additionally, we discuss the diagnosis and management of supraventricular tachycardia and Wolff-Parkinson-White syndrome in the neonatal and pediatric population, which is essential knowledge for an Emergency Physician.

Group A streptococcus (GAS) is a major bacterial pathogen affecting children globally. Approximately 15% of school-age children experience a symptomatic episode of GAS culture-positive pharyngitis each year. Although the incidence of invasive GAS disease under these circumstances is low (0.5%-2%), an increasing number of invasive GAS cases have been reported over the last 2 decades. This report describes a 7-year-old boy who, after being treated for GAS pharyngitis, developed a fatal streptococcal toxic shock syndrome.
