ReviewRecent progress in understanding pediatric pulmonary hypertension.
Pulmonary artery hypertension (PAH) in children contributes significantly to morbidity and mortality in diverse pediatric cardiac, lung, hematologic and other diseases. Advances in pulmonary vascular biology over the past few decades have significantly expanded therapeutic strategies; however, many unique issues persist regarding our understanding of pediatric PAH. ⋯ Despite many advances, long-term outcomes for children with PAH remain guarded and substantial challenges persist, especially with regard to understanding mechanisms and approach to severe PAH. Future studies are needed to develop novel biomarkers, clinical endpoints and interventions for young children with diverse causes of PAH.

ReviewAdvances in simulation for pediatric critical care and emergency medicine.
Routine integration of simulation into healthcare education and practice has gained momentum. Simulation is particularly important to acute and critical care pediatrics, as it offers alternative methods of training for high-risk and/or lower-frequency events in children. This review will discuss the recent advances in simulation education for pediatric critical care and emergency medicine and assess its potential for future growth through these subspecialties. ⋯ High-fidelity simulation is emerging as a powerful tool for pediatric emergency medicine and critical care education through both individual and team-based training exercises. Programs can be tailored to meet specific institutional needs and budget limitations. As pediatric simulation-based programs evolve, further progress is anticipated in acute and critical care outcomes.

In this review, we discuss the recent advances in our understanding of the cause, pathogenesis, presentation, diagnosis, treatment, and prognosis of interstitial lung disease (ILD) in children. ⋯ Children's interstitial lung diseases are rare diffuse lung diseases resulting from a variety of pathogenic processes that include genetic factors, association with systemic disease processes, and inflammatory or fibrotic responses to stimuli. There are unique causes and presentations seen in infancy. Diagnosis in these disorders is made by the summation of clinical, radiologic, and pathologic findings.

Intravenous and enteral fluid resuscitation are frequently used therapies in the management of pediatric patients in emergency departments and critical care settings. Any state of intravascular fluid deficit, ranging from mild dehydration due to gastroenteritis to fulminant septic shock, requires careful assessment and early restoration of hemodynamic stability. Rapid fluid resuscitation has gained increased recognition since the most recent pediatric shock management guidelines. We sought to review the evidence for rapid fluid resuscitation and to outline its clinical indications, implementation, and potential associated risks. ⋯ Rapid fluid resuscitation is most commonly used for children with moderate-to-severe dehydration, or for patients in shock to restore circulation. Concerns regarding potential for fluid overload and electrolyte disturbances and regarding the method of rehydration (i.e., enteral versus parenteral) raise some debate about the safety and efficacy of rapid fluid resuscitation in the pediatric patient. Recent studies show that early, aggressive fluid resuscitation of up to 60 ml/kg within 1-2 h may be necessary to replenish circulating intravascular fluid volume. Complications of severe electrolyte disturbances, cerebral edema, or uncontrolled hemorrhage are uncommon and can often be avoided with early clinical assessment and reassessments throughout the resuscitation. In the mildly to moderately dehydrated child, enteral fluid resuscitation with the aid of an antiemetic such as ondansetron can be as effective and efficient as intravenous fluid resuscitation.

ReviewAntibiotic prophylaxis and the prevention of surgical site infection.
Surgical site infection (SSI) is one of the most common complications of surgery in both adults and children. The purpose of the present review is to highlight the progress in the understanding of SSIs and the current role of antimicrobial prophylaxis (AMP). ⋯ Improvement in the perioperative care of children has reduced both the incidence and outcomes of SSI. However, several controversies still exist in the use of AMP in children. Future work by pediatricians, pediatric surgeons, and pediatric infectious disease specialists will enable us to better understand the specific indications and appropriate AMP in children.
