Current data on fosfomycin usage in children are limited. We present data on the clinical use of intravenous (IV) fosfomycin in children. Hospitalized patients who received ≥3 days of IV fosfomycin between April 2021 and March 2023 were analyzed retrospectively.

This study aimed to retrospectively evaluate the baseline and follow-up viral loads and viral clearance times in cases followed for asymptomatic and symptomatic congenital cytomegalovirus (cCMV) infection between August 2010 and August 2022. Among 93 cases, they had asymptomatic (n: 55) and symptomatic (n: 38). The median baseline blood viral load detected in the symptomatic cCMV (ScCMV) infection (13 054 IU/mL) was significantly higher than that of asymptomatic cCMV (AcCMV) infection (4636 IU/mL) (p < 0.

Background: Herbaspirillum species are nonfermenting, aerobic, helical or curved, Gram-negative bacteria belonging to the class Betaproteobacteria, order Burkholderiales. To date, only a few studies have reported on the epidemiology, clinical symptoms, antibiotic susceptibility profiles, treatment and outcomes of Herbaspirillum huttiense -related infections in pediatric patients.

Methods: The aim of this study was to present 3 years of H.

Objective: Adenovirus pneumonia is a common cause of community-acquired pneumonia in children and can mimic bacterial pneumonia, but there are few publications on its radiographic features. This study has evaluated the chest radiography findings of community-acquired adenovirus pneumonia in children. The frequency of radiological findings mimicking bacterial pneumonia was investigated.

Background: With recent developments in the field of microbiology, an increasing number of yeasts and molds with the potential to cause infections in humans are identified every year. In addition to the challenges in identifying clinical isolates, there is limited antifungal susceptibility data available for Phialemonium species, leading to uncertainty in optimal treatment recommendations.

Methods: In this article, catheter-related bloodstream infections caused by Phialemonium curvata (previously Phialemonium curvatum ) in 3 immunosuppressed patients are presented.

Background: There is limited data on the pattern and severity of myocardial injury in patients with COVID-19 vaccination associated myocarditis.

Objective: We aimed to define the myocardial damage occurring after BNT162b2 vaccination, raise awareness about adverse reactions developing after vaccination, and determine the patterns and scope of Cardiac magnetic resonance imaging (MRI) findings.

Patients/methods: A total of 9 patients diagnosed with vaccine-associated myopericarditis were followed up.

Article Synopsis
  • This study investigates if parents' vaccination against COVID-19 can reduce hospitalizations for children who contract the virus, focusing on data from the delta variant period in Turkey (August to October 2021).
  • The findings reveal that children whose parents were fully vaccinated were less likely to be hospitalized, with a significant correlation between parental vaccination status and the hospitalization rates of their children.
  • The conclusion suggests that fully vaccinating both parents can provide indirect protection for their children against severe illness from COVID-19, indicating a need for further research on different COVID-19 variants.

Article Synopsis
  • The study investigates multisystem inflammatory syndrome in children (MIS-C), which can lead to severe complications or death, focusing on cases from 25 hospitals in Turkey between April and October 2020.
  • It analyzed the medical records of 101 patients, primarily aged 7, finding high rates of fever, fatigue, and gastrointestinal issues, with significant laboratory abnormalities and a notable proportion requiring intensive care.
  • The research underscores the importance of recognizing MIS-C, especially in previously healthy children presenting with persistent fever and other symptoms; most were treated effectively with immunomodulatory therapies, though there were reported fatalities.

Unlabelled: Multisystemic inflammatory syndrome (MIS-C) diagnosis remains difficult because the clinical features overlap with Kawasaki disease (KD). The study aims to highlight the clinical and laboratory features and outcomes of patients with MISC whose clinical manifestations overlap with or without KD. This study is a retrospective analysis of a case series designed for patients aged 1 month to 18 years in 28 hospitals between November 1, 2020, and June 9, 2021.

Background: Invasive aspergillosis (IA) is an important cause of morbidity and mortality in immunosuppressed children. Early detection of the infection can improve prognosis in this patient population.

Objectives: To investigate the utility of galactomannan antigen assay (GM-EIA) as a diagnostic tool for IA in at-risk paediatric patients.

  • The study analyzed pediatric COVID-19 cases across 32 hospitals in Turkey, focusing on the epidemiological, clinical, and laboratory characteristics of the disease in children from March 16 to June 15, 2020.
  • A total of 1,156 cases were confirmed, with a slightly higher proportion of males (50.3%) compared to females (49.7%), and the median age of the patients was 10.75 years; common symptoms included fever (50.4%) and cough (46.9%).
  • The severity of illness varied, with 22.7% asymptomatic, 57.7% experiencing mild symptoms, and 1.5% being classified as severe; 12.9% had

Background And Objective: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyper-inflammatory disease. It is difficult to differentiate between primary and secondary HLH based on clinical findings at the onset of disease. We aimed to find parameters that can help to differentiate primary and secondary HLH at initial diagnosis especially for physicians working in developing countries.

We report a case of a 3-month-old Turkish girl who had clinical and laboratory features of Glanzmann's thrombasthenia associated with asymmetric crying facies (ACF). Although ACF is a minor anomaly, it should not be forgotten that it can be accompanied by major congenital anomalies and if this finding is detected, other anomalies should be investigated.
