Sepsis management demands early diagnosis and timely treatment that includes source control, antimicrobial therapy, and resuscitation. Currently employed diagnostic tools are ill-equipped to rapidly diagnose sepsis and isolate the offending pathogen, which limits the ability to offer targeted and lowest-toxicity treatment. Cutting edge diagnostics and therapeutics in development may improve time to diagnosis and address two broad management principles: (1) source control by removing the molecular infectious stimulus of sepsis, and (2) attenuation of the pathological immune response allowing the body to heal. This review addresses novel diagnostics and therapeutics and their role in the management of sepsis.

This review focuses on the identification, evaluation, management, and stabilization of a variety of acquired cardiac conditions, such as cardiomyopathies, inflammatory cardiac disease, and Kawasaki disease, which commonly require care in the pediatric intensive care unit (PICU). Pediatric cardiomyopathies comprise a spectrum of acquired or congenital myocardial diseases in which there are abnormalities of cardiac size and ventricular wall thickness, along with ventricular performance. The inflammatory diseases of the heart include acute myocarditis and pericarditis. Cardiac sequelae of Kawasaki disease resemble a self-limited vasculitis, but in rare instances may present with hemodynamic instability requiring vasopressor support. Care in the PICU affords both monitoring and management opportunities. [Pediatr Ann. 2018;47(7):e280-e285.].

Although rare in the general pediatric population, the incidence of pericardial effusion is significantly higher in pediatric patients undergoing hematopoietic stem cell transplant (HCT) with a reported incidence of up to 16.9%. The development of pericardial effusion in this setting is associated with higher mortality. Although pericardiocentesis is a relatively safe procedure for treating pericardial effusion, it is invasive, painful, and exposes an immunosuppressed patient to the risks of infection, bleeding, and injury to surrounding structures. Given the procedural risks of pericardiocentesis, systemic steroids are often administered for the treatment of pericardial effusion given their use for pericarditis in the general population. However, the effectiveness of systemic steroids for the treatment of pericardial effusion in the pediatric HCT population has not been confirmed. We studied the role of systemic steroids, administered at the time of initial pericardiocentesis performed for pericardial effusion, in preventing repeat pericardiocentesis. A total of 37 pericardiocenteses after HCT were performed during the study period with 25 patients undergoing first-time pericardiocentesis and 15 of those patients receiving systemic steroids. Eight patients required repeat pericardiocentesis; 5 of 15 (33%) received steroids and 3 of 10 (30%) did not receive steroids. Our data in this small cohort of pediatric HCT patients did not show a significant difference in the need for repeat pericardiocentesis with the use of systemic steroids, initiated within 48 hours of pericardiocentesis.
