Article Synopsis
  • The study aimed to assess the status of point-of-care ultrasound (POCUS) usage, perceptions, and educational barriers in pediatric emergency departments (PEDs) and pediatric intensive care units (PICUs) in Turkey.
  • The survey revealed that a significant majority of PEDs (84.2%) and all PICUs (100%) utilize POCUS, mainly for thoracic and cardiovascular assessments, but face challenges like lack of equipment, manpower, and training.
  • Participants emphasized the importance of mandatory POCUS training during fellowship programs to enhance usage and improve patient outcomes in pediatric care.

Article Synopsis
  • The study aimed to differentiate between COVID-19 and other respiratory viral infections in critically ill children to prioritize care and avoid neglecting non-COVID cases.
  • Conducted in 24 pediatric intensive care units, the research evaluated radiological findings in 225 patients from March to May 2020, with 81 confirmed COVID-19 cases.
  • Results showed that chest X-rays of COVID-19 patients were more likely to appear normal, while other viruses like rhinovirus showed distinct patterns, indicating non-specific radiological findings in COVID-19.

 This study aimed to evaluate factors affecting the quality of life (QOL) of parents of children who underwent placement of a tracheostomy while in the pediatric intensive care unit (PICU) through postdischarge use of a standardized questionnaire, Functional Status Scale (FSS) for patients, and WHOQoL-BREF (a QOL scale) for parents.  The parents were initially contacted by telephone, postdischarge, during which the standardized questionnaire was completed. The functional status of the patients was evaluated using the FSS, and the QOL of parents was determined through use of the WHOQoL-BREF scale.

Background: Identifying mortality risk in critically ill children is central to diagnostic and treatment practices. For this purpose, scoring systems, such as the Pediatric Index of Mortality 3 (PIM 3), have been proposed; however, the role of biochemical markers, such as albumin-corrected anion gap (cAG) and lactate clearance (LC), in predicting mortality in pediatric intensive care unit (PICU) patients is yet to be explored.

Aims: To evaluate the predictive value of the cAG and LC for mortality in pediatric patients admitted to a PICU.

Objective: We aimed to evaluate clinical and echocardiographic features of the children diag- nosed with multisystem inflammatory syndrome related to severe acute respiratory syndrome coronavirus-2 infection and determine early and mid-term cardiovascular outcomes.

Materials And Methods: We retrospectively evaluated 38 children who were diagnosed with multisystem inflammatory syndrome in our hospital between November 2020 and November 2021. Cardiovascular evaluations were performed during hospitalization, at the first, the second, and the third months after discharge, and then cardiac evaluation was repeated at 3-month intervals until a median of 24 weeks (range: 9-56 weeks).

Microbiota composition might play a role in the pathophysiology and course of sepsis, and understanding its dynamics is of clinical interest. Invasive meningococcal disease (IMD) is an important cause of community-acquired serious infection, and there is no information regarding microbiota composition in children with meningococcemia. In this study, we aimed to evaluate the intestinal and nasopharyngeal microbiota composition of children with IMD.

Objectives: Maple syrup urine disease (MSUD) is an autosomal recessive inherited disorder. Despite the advances in medical nutrition therapies, classical phenotype causes severe neurological disorders and sudden death. It is known that MSUD patients do not experience metabolic attacks despite their free diet after liver transplantation (LT).

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.

Background: Pediatric head trauma is the most common presentation to emergency departments. Increased intracranial pressure (ICP) may lead to secondary brain damage in head trauma and early diagnosis of increased ICP is very important. Measurement of optic nerve sheath diameter (ONSD) is a method that can be used for determining increased ICP.

Background: We prospectively compared restrictive and liberal transfusion strategies for critically ill children regarding hemodynamic and laboratory parameters.

Methods: A total of 180 children requiring packed red blood cells (PRBCs) were randomized into two groups: the liberal transfusion strategy group (transfusion trigger < 10 g/dL, Group 1) and the restrictive transfusion strategy group (transfusion trigger ≤ 7 g/dL, Group 2). Basal variables including venous/arterial hemoglobin, hematocrit and lactate levels; stroke volume; and cardiac output were recorded at the beginning and end of the transfusion.
