Candida lusitaniae Fungemia in Children: A multicenter case series of emerging pathogen.

Candida lusitaniae fungemia is a serious infection which is rarely reported in children. The aim of this study is to describe a case series of Candida lusitaniae fungemia and review previous publications regarding this rare pathogen. This is a multicenter case series of children diagnosed with Candida lusitaniae fungemia. Eighteen cases which occurred over a 15-year period in 5 tertiary hospitals were included. Additionally, a review of the literature regarding Candida lusitaniae fungemia in children was performed. Eighteen cases were enrolled, 11/18 (61%) were males, with a mean age of 2.3 years. All patients had severe underlying diseases and risk factors for opportunistic infection, most commonly prematurity and malignancies. More than one third of cases occurred during the last two years of the study period. All isolates were susceptible to all tested antifungals. Survival rate following the acute infection was 94% whereas survival rate of 14 previously published cases was 71% with the most common underlying diseases being CGD and malignancies. Candida lusitaniae fungemia is not a common event in the pediatric population, occurring exclusively in children with severe underlying diseases and significant risk factors. This cohort revealed better clinical outcomes than previously reported. All tested isolates were susceptible to all antifungal agents, variability in susceptibility as previously reported was not found in this study. The allegedly higher rate of infection in recent years is in need of further investigation in larger prospective studies in order to conclude if a real trend is at play.

Candida lusitaniae fungemia is a serious infection rarely reported in children. This cohort revealed better clinical outcomes than previously reported. All tested isolates were susceptible to all antifungal agents. The higher rate of infection in recent years is in need of further investigation.

Transient Cardiac Injury in Adolescents Receiving the BNT162b2 mRNA COVID-19 Vaccine.

BACKGROUND: Vaccines are paramount in the effort to end the coronavirus disease 2019 global epidemic. BNT162b2 is approved for the vaccination of adolescents over 16 years of age. Systemic adverse events were scarce though the pretested cohort of this age group was relatively small. The aim of the current study is to raise awareness for potential adverse reactions. METHODS: This is a case series of patients diagnosed with perimyocarditis following vaccination. Patients were compiled from 3 pediatric medical centers in Israel through a network of pediatricians and data regarding those cases was collected. In addition, incidence of perimyocarditis during the vaccination period was compared with previous years. RESULTS: All patients were males 16-18 years old, of Jewish descent, who presented with chest pain that began 1-3 days following vaccination (mean, 2.1 days). In 6 of the 7 patients, symptoms began following the 2nd dose and in 1 patient following the 1st dose. All cases were mild and none required cardiovascular or respiratory support. The incidence of perimyocarditis during the vaccination period was elevated in comparison to previous years. CONCLUSIONS: This case series describes a time association between coronavirus disease 2019 vaccine and perimyocarditis in adolescents. All cases were mild, although only long-term follow-up can reveal the true impact of this cardiac injury. While it seems that the incidence of perimyocarditis during the vaccination campaign period is increased, a more comprehensive data collection on a wider scale should be done. We hope this report will serve as a reminder to report events and allow for analysis of potential adverse reactions.

Delayed diagnosis of paediatric appendicitis during the COVID-19 pandemic.

AIM: To present seven paediatric patients with appendicitis, all with late diagnosis resulting from different aspects of the fear from the current global COVID-19 pandemic. METHODS: Cases were collected from three paediatric surgical wards. Comparison between complicated appendicitis rates in the COVID-19 era and similar period in previous year was performed. RESULTS: All seven children presented with complicated appendicitis. Main reasons for the delayed diagnosis during the COVID-19 era were parental concern, telemedicine use and insufficient evaluation. Higher complication rates were found during the COVID-19 era compared to similar period in previous year (22% vs 11%, P-value .06). CONCLUSION: The fear from COVID-19 pandemic may result in delayed diagnosis and higher complication rates in common paediatric medical conditions. We believe caregivers and healthcare providers should not withhold necessary medical care since delay in diagnosis and treatment in these routinely seen medical emergencies may become as big of a threat as COVID-19 itself.

Factors associated with early phosphate levels in preterm infants.

To investigate perinatal factors and early morbidities associated with early serum phosphate (sPhos) levels in a cohort of preterm infants. Retrospective data were obtained from the medical records of a cohort of 454 infants born at < 32 weeks gestational age. Serum phosphate levels were directly associated with gestational age, body weight z-score, and Apgar scores and inversely associated with timing of enteral nutrition initiation and diet consisting of mostly breast milk. Maternal hypertension, lactate levels, early symptomatic hypotension, and total protein supplemented on days 1 to 3 were also inversely associated with sPhos. Morbidities that were found to be associated with sPhos did not persist after adjustment for confounding factors.Conclusions: We report a novel association between early sPhos and timing and content of enteral nutrition, as well as with the early neonatal hemodynamic condition of preterm infants. This information may help identify infants at risk for low sPhos and aid in the nutritional strategy utilized in these patients. This study did not identify early morbidities associated with sPhos. What is Known: • High initial amino acid intake is associated with increased risk of Refeeding like syndrome and hypophosphatemia, among preterm infants. What is New: • Early enteral nutrition, starting within the first 72 h of life, is associated with higher serum phosphate (sPhos) compared to nothing per os (NPO). • sPhos was not associated with early adverse neonatal outcomes.
