Hemophagocytic lymphohistiocytosis (HLH) is a multisystem inflammatory disorder due to cytokine overproduction from excessively activated lymphocytes and macrophages. HLH has been divided into two subgroups: primary HLH and secondary HLH. Primary HLH includes PRF1, UNC13D, STX11, STXBP2, RAB27A, LYST, SH2D1A and XIAP gene mutations; and secondary HLH is associated with infections, malignancies and autoimmune diseases. ⋯ Analysis of clinical phenotypes of XLP patients suggests that XLP predominantly shows familial HLH phenotypes, whereas some XLP patients present sporadic HLH. For many decades, clinicians and investigators have been concerned with possible XLP in young boys presenting with Epstein-Barr-virus-associated HLH. This review aims to describe the new knowledge about XLP and to draw the attention of the pediatrician to XLP, which should be differentiated from other forms of HLH.

In this study, we aimed to evaluate the role of fever, hypothermia, and temperature instability in term and preterm newborns during the first 3 days of life and to identify risk factors for early onset sepsis (EOS) among newborns presenting with these temperature symptoms. ⋯ Every seventh newborn hospitalized at our neonatal intensive care unit developed fever, hypothermia and/or temperature instability during the first 3 days of life. Two-thirds of them had culture-proven or clinical sepsis. Temperature symptoms were rarely observed in EOS-negative newborns (8%) but despite low sensitivity, were highly specific for bacterial infection in preterm and term newborns.

The Canadian Paediatric Triage and Acuity Scale (P-CTAS) is used and modified at hospitals as a triage tool for pediatric patients before they are seen in emergency rooms. Pediatric surgery patients account for very few of the many patients in emergency departments, but they should be triaged as emergency or urgent because they might be candidates for surgery. Problems with and improvements for triaging pediatric surgery patients using the P-CTAS were studied. ⋯ P-CTAS worked well for pediatric surgery patients, and it needs to be modified and improved for such patients based on these results.

Comparative Study
Electrocardiogram shows reliable heart rates much earlier than pulse oximetry during neonatal resuscitation.
The aim of this study was to determine the usefulness of the three-lead electrocardiogram (ECG) during neonatal resuscitation. ⋯ ECG was a safe and reliable method for showing HR, and was used to determine the initiation and the effectiveness of resuscitation in the delivery room.

The aim of the present study was to examine short-term and long-term mortality following discharge from the pediatric intensive care unit (PICU). ⋯ A 2 year follow-up period seems sufficient for a comprehensive mortality analysis of PICU patients. Severity of critical illness is the key factor of short-term mortality, whereas comorbidity is the major determinant of long-term mortality.
