Varicella in the 21st Century.

Varicella is a highly contagious disease caused by the varicella-zoster virus and has a wide range of clinical presentations. Varicella can cause mild disease in infants born to infected persons who are immunized as a result of previous vaccination or previous clinical or subclinical infection. However, varicella can also lead to severe life-threatening disease in infants, particularly for those born to nonimmunized persons. In this review, we will summarize the natural history of varicella-zoster infection in pregnant persons, infants with congenital varicella syndrome, and infants with postnatal varicella infection. We will also provide guidance about isolation recommendations and chemoprophylaxis for exposed hospitalized infants. Finally, we will describe risk factors for developing disseminated disease and review the approach to treatment of infected infants.

Reducing Procedural Pain and Avoiding Peripheral Intravenous Catheters by Implementing a Feeding Protocol for Late Preterm Infants: A Quality Improvement Project.

BACKGROUND: Late preterm births account for a large portion of preterm births, yet the optimal method of nutrition and enteral feeding in this population remains unclear and often involves intravenous (IV) fluids. PURPOSE: To develop and implement a late preterm feeding protocol in order to decrease the necessity of IV access, decrease the use of starter parenteral nutrition (PN), and reduce the pain endured by an infant in the neonatal intensive care unit. METHODS: The Plan-Do-Study-Act quality improvement model was utilized as a framework for the implementation of this quality improvement project. A literature review was conducted and subsequently, a feeding protocol was developed and included the more judicious use of starter PN. This protocol was implemented, evaluated, and adopted. A second Plan-Do-Study-Act cycle was completed with the addition of an auto-text reminder incorporated into admission notes in the electronic medical record. RESULTS: The implementation of the protocol significantly reduced placement of IV access and the use of starter (PN) in late preterm infants without considerable differences in balancing measures. The percentage of infants who received peripheral IV access declined considerably from 70% to 42% (P = .0017) subsequently, less pain endured by the infants. There was a decrease in the initiation of starter PN from 55% to 7% (P < .00001). IMPLICATIONS FOR PRACTICE AND RESEARCH: Administering enteral feedings on admission to stable, late preterm infants, reduced the need for peripheral IV access and thus decreased pain from this procedure. More research needs to be done to determine the optimal amount of feedings to administer in the first 24 hours of life for the late preterm infant as well as the best method for supplementation if necessary.

Postmortem diagnosis of very long chain acyl-CoA dehydrogenase (VLCAD) deficiency in a neonate with sudden cardiac death.

Very long chain acyl-CoA dehydrogenase (VLCAD) deficiency is an autosomal recessive long chain fatty acid ß-oxidation disorder with a variable clinical spectrum, ranging from an acute neonatal presentation with cardiac and hepatic failure to childhood or adult onset of symptoms with hepatomegaly or rhabdomyolysis provoked by illness or exertion. Neonatal cardiac arrest or sudden unexpected death can be the presenting phenotype in some patients, emphasizing the importance of early clinical suspicion and intervention. We report a patient who had a cardiac arrest and died at one day of age. Following her death, the newborn screen reported biochemical evidence of VLCAD deficiency, which was confirmed with pathologic findings at autopsy and by molecular genetic testing.

A quality improvement project improving the value of iNO utilization in preterm and term infants.

OBJECTIVE: Inhaled NO (iNO) is used in the NICU for management of hypoxemic respiratory failure. The cost of iNO is significant and does not consistently improve outcomes in infants <34 weeks. PROJECT DESIGN: Our team used The Model for Improvement to design a quality improvement project to utilize iNO for appropriate indications, ensure response to therapy and initiate timely weaning. The project was carried out at a Level IV NICU and successful interventions spread to a smaller Level III NICU. RESULTS: This project demonstrated significant improvement in all measures; total iNO hours per month, average iNO hours per patient, and the percentage of prolonged iNO courses. With an estimated cost of $115/h, the cost per patient for iNO use declined by half from $21,620 to $10,580. CONCLUSIONS: Our team improved the value of iNO utilization at our institution and spread successful interventions to another NICU in our network.
