In this nationwide retrospective study, a substantial decline in the incidence of multisystem inflammatory syndrome in children over 3 successive pandemic waves characterized by different severe acute respiratory syndrome coronavirus 2 variants was documented-from 3.4 of 1000 to 1.1 of 1000 and finally to 0.25 of 1000 confirmed severe acute respiratory syndrome coronavirus 2 positive cases (P < 0.0001), respectively, whereas clinical findings and severity did not significantly vary., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2022 Wolters Kluwer Health, Inc.

A unified surveillance mechanism for hand hygiene and hospital-acquired infections for pediatric wards is lacking in Europe. We managed to setup such a mechanism in 9 pediatric intensive care units in 7 European countries, using World Health Organization's definitions and common methodology which allows for benchmarking among units and countries. Median hand hygiene compliance was found high 82.3% (interquartile range 71.6-94.5%), but gaps in practices were identified., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

Children and adolescents with severe acute respiratory syndrome coronavirus 2 infection usually have a milder illness, lower mortality rates and may manifest different clinical entities compared with adults. Acute effusive pericarditis is a rare clinical manifestation in patients with COVID-19, especially among those without concurrent pulmonary disease or myocardial injury. We present 2 cases of acute pericarditis, in the absence of initial respiratory or other symptoms, in adolescents with COVID-19., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: Misuse, overuse of antimicrobials and increasing rates of antimicrobial resistance are well-recognized problems throughout Europe. The aim of this survey was to describe the current pediatric antibiotic stewardship (PAS) landscape across Europe and identify gaps, in terms of national programs, networks and guidelines., Methods: A survey of 17 questions was circulated in July 2019 among 24 European pediatric infectious disease researchers and clinicians, professors and heads of department on the existence of PAS programs, national networks and meetings, established competencies, metrics and guidelines., Results: We received responses from 23 countries. National guidelines on the management of children with common infections treated in hospital settings exist in 15 of 23 (70%); only 8 of 15 (53%) had been updated within the previous 4 years. Most provide guidance on antibiotic initiation and duration (14 of 15, 93%), but few on when to transition from intravenous to oral antibiotics (7 of 15, 47%). National PAS competencies have only been developed in 4 countries; only 1 addressed both community and hospital prescribing. Organized national PAS networks are only established in the United Kingdom and Germany; 21 of 23, 91% countries had no agreed metric for antibiotic prescribing in children; 2 of 23 were based on daily defined doses., Conclusions: Fragmented implementation of PAS programs, no agreed metrics, lack of established PAS competencies and national PAS networks along with inexistent funding is alarming in view of existing high rates of antimicrobial resistance in Europe.

We report the case of an 11-year-old immunocompetent patient presenting with a 2-week history of upper back pain, diagnosed with thoracic vertebral osteomyelitis and a paraspinal abscess caused by Bartonella henselae. He was treated with gentamicin and doxycycline followed by oral rifampicin and doxycycline with favorable outcome.

Background: Visceral leishmaniasis (VL) remains an important public health problem in endemic regions. Current antileishmanial agents share several limitations including potentially serious side effects and the risk of clinical failure., Objectives: Aim of this study was to examine the effectiveness and safety of short-course liposomal amphotericin B (L-AmB) regimens in the treatment of childhood VL in our area., Methods: The cases of 43 VL patients (20 males; 23 females; mean age: 4.6 years) treated at a tertiary children's hospital over an 11-year period were retrospectively reviewed. Diagnosis was confirmed with identification of Leishmania spp. in bone marrow samples and/or a positive serologic test. All patients were treated with 5 different L-AmB regimens at a dose of 18-22 mg/kg., Results: Initial response to treatment was attained in all patients (100%), while definitive cure at 6 months was achieved in 98% of patients. Adverse effects were recorded in 14 children and consisted mostly of infusion reactions and electrolyte disorders. Self-limiting nephrotoxicity was observed in 3 patients including a 12-year-old girl in whom acute kidney injury was developed. In addition, ventricular arrhythmias developed in a 13-year-old boy necessitating drug discontinuation. Although side effects were more frequent with the 2-day regimen, the difference with regard to toxicity between dosing regimens was not significant., Conclusions: Short-course L-AmB regimens are effective and safe for the treatment of childhood VL in our area. Our findings suggest that large L-AmB doses can possibly account for a higher rate of adverse events including nephrotoxicity.

Background: Hand hygiene (HH) is the most effective way to prevent health care-associated infections and the spread of antimicrobial-resistant pathogens. The aim of our study was to assess the existing HH resources and current HH practices at 2 hospitals in Athens, Greece., Methods: Observational HH data and an inventory of HH resources were collected from 13 wards including medical/surgical, oncology/transplant and intensive care units, during 65, 1-hour observations periods., Results: A total of 1271 HH opportunities were observed during the study period, including 944 of Health Care Workers (HCW) and 327 of visitors and parents. The nursing HH compliance was highest (49%) followed by medical compliance (24%, P < 0.001). HCW HH compliance was highest in intensive care units and the transplant unit (64-87%). The rate of appropriate HH for HCW was 22.6%. HCW most commonly used soap and water (76.1%). The HH procedure was more likely to be appropriate when soap and water were used as compared with alcohol based hand rub (64.6% and 47.5%, P = 0.006). A marginally significant association was identified between the HH compliance rate and the number of alcohol based hand rub dispensers per room (P = 0.057). In visitors and parents, the HH compliance was found to be 19%, whereas the rate of appropriate HH was 8.9%., Conclusions: Low levels of HH were observed.
