Article Synopsis
  • * It found that the RSV only group had lower pH and higher rates of bronchiolitis, while the RSV with viral agents group experienced longer hospital stays and more severe symptoms.
  • * Additionally, cases with bacterial co-infections were generally younger and had different clinical markers, highlighting that combined viral and bacterial infections can worsen RSV severity and impact treatment approaches like High Flow Nasal Cannula-Oxygen Therapy.

Introduction: Rare and ultra-rare genetic conditions significantly contribute to infant morbidity and mortality, often presenting with atypical features and genetic heterogeneity that complicate management. Rapid genome sequencing (RGS) offers a timely and cost-effective approach to diagnosis, aiding in early clinical management and reducing unnecessary interventions. This pilot study represents the inaugural use of next-generation sequencing (NGS) as a diagnostic instrument for critically ill neonatal and pediatric ICU patients in a Turkish hospital setting.

Introduction: There have been some significant changes regarding healthcare utilization during the COVID-19 pandemic. Majority of the reports about the impact of the COVID-19 pandemic on diabetes care are from the first wave of the pandemic. We aim to evaluate the potential effects of the COVID-19 pandemic on the severity of diabetic ketoacidosis (DKA) and new onset Type 1 diabetes presenting with DKA, and also evaluate children with DKA and acute COVID-19 infection.

Extracorporeal membrane oxygenation (ECMO) is used in pediatric patients with severe cardiopulmonary failure who do not respond to conventional therapy; only a few studies have been conducted in Turkey. We present the experience of pediatric ECMO with the aim of showing factors affecting mortality. We retrospectively reviewed our ECMO database to identify patients who received ECMO from October 2015 to March 2018.

Therapeutic plasma exchange (TPE) is an effective treatment method in selective indications. Secondary to access and technical features, it is more difficult to apply in pediatric population than adults. The aim of this study is investigate safety, clinical indications, and results of this method in critically ill pediatric patients who need TPE treatment.

Objectives: Anticoagulation is used to prevent filter clotting in patients undergoing continuous renal replacement therapy. Regional citrate anticoagulation is associated with lower rates of bleeding complications and prolongs the filter life span; however, a number of metabolic side effects had been associated with this therapy. The aim of this study was to evaluate the effect and safety of citrate versus heparin anticoagulation for continuous renal replacement therapy in critically ill children.

Aim: Healthcare-associated infections cause increased morbidity and mortality in intensive care units. In this study, it was aimed to compare infections with multi-drug resistance and extended drug resistance, while evaluating the characteristics of resistant Gram-negative infections in the pediatric intensive care unit in our university hospital.

Material And Methods: In this study, pediatric patients who were found to have Gram-negative infections during hsopitalization in the pediatric intensive care unit in our faculty between January 2011 and December 2015, were evaluated retrospectively.

Objectives: To identify prognostic factors and indications in patients receiving continuous renal replacement therapy (CRRT) in the pediatric intensive care unit (PICU), and to demonstrate their effect on mortality.

Methods: A total of 63 patients admitted between 2011 and 2014 were included in the study. The demographic information, pediatric risk of mortality (PRISM) scores, vasoactive-inotropic score, indication for CRRT, time of starting CRRT, presence of fluid overload, durations of CRRT, and pediatric intensive care unit (PICU) stay were compared between survivors and non-survivors.

Background: The oral ingestion of elemental mercury is unlikely to cause systemic toxicity, as it is poorly absorbed through the gastrointestinal system. However, abnormal gastrointestinal function or anatomy may allow elemental mercury into the bloodstream and the peritoneal space. Systemic effects of massive oral intake of mercury have rarely been reported.
