Background
Evidence is urgently needed to support treatment decisions for children with multisystem inflammatory syndrome (MIS-C) associated with severe acute respiratory syndrome coronavirus 2.
Methods
We performed an international observational cohort study of clinical and outcome data regarding suspected MIS-C that had been uploaded by physicians onto a Web-based database. We used inverse-probability weighting and generalized linear models to evaluate intravenous immune globulin (IVIG) as a reference, as compared with IVIG plus glucocorticoids and glucocorticoids alone. There were two primary outcomes: the first was a composite of inotropic support or mechanical ventilation by day 2 or later or death; the second was a reduction in disease severity on an ordinal scale by day 2. Secondary outcomes included treatment escalation and the time until a reduction in organ failure and inflammation.
Results
Data were available regarding the course of treatment for 614 children from 32 countries from June 2020 through February 2021; 490 met the World Health Organization criteria for MIS-C. Of the 614 children with suspected MIS-C, 246 received primary treatment with IVIG alone, 208 with IVIG plus glucocorticoids, and 99 with glucocorticoids alone; 22 children received other treatment combinations, including biologic agents, and 39 received no immunomodulatory therapy. Receipt of inotropic or ventilatory support or death occurred in 56 patients who received IVIG plus glucocorticoids (adjusted odds ratio for the comparison with IVIG alone, 0.77; 95% confidence interval [CI], 0.33 to 1.82) and in 17 patients who received glucocorticoids alone (adjusted odds ratio, 0.54; 95% CI, 0.22 to 1.33). The adjusted odds ratios for a reduction in disease severity were similar in the two groups, as compared with IVIG alone (0.90 for IVIG plus glucocorticoids and 0.93 for glucocorticoids alone). The time until a reduction in disease severity was similar in the three groups.
Conclusions
We found no evidence that recovery from MIS-C differed after primary treatment with IVIG alone, IVIG plus glucocorticoids, or glucocorticoids alone, although significant differences may emerge as more data accrue. (Funded by the European Union’s Horizon 2020 Program and others; BATS ISRCTN number,

Active surveillance of healthy children provided evidence of respiratory illness burden associated with several viruses, with a substantial burden in older children.
Pertussis has reemerged as a problem across the world. To better understand the nature of the resurgence, we reviewed recent epidemiologic data and we report disease trends from across the world. Published epidemiologic data from January 2000 to July 2013 were obtained via PubMed searches and open-access websites. Data on vaccine coverage and reported pertussis cases from 2000 through 2012 from the 6 World Health Organization regions were also reviewed. Findings are confounded not only by the lack of systematic and comparable observations in many areas of the world but also by the cyclic nature of pertussis with peaks occurring every 3-5 years. It appears that pertussis incidence has increased in school-age children in North America and western Europe, where acellular pertussis vaccines are used, but an increase has also occurred in some countries that use whole-cell vaccines. Worldwide, pertussis remains a serious health concern, especially for infants, who bear the greatest disease burden. Factors that may contribute to the resurgence include lack of booster immunizations, low vaccine coverage, improved diagnostic methods, and genetic changes in the organism. To better understand the epidemiology of pertussis and optimize disease control, it is important to improve surveillance worldwide, irrespective of pertussis vaccine types and schedules used in each country.
Background: Although the incidence of serious morbidity with childhood pneumonia has decreased over time, empyema as a complication of community-acquired pneumonia continues to be an important clinical problem. We reviewed the epidemiology and clinical management of empyema at 8 pediatric hospitals in a period before the widespread implementation of universal infant heptavalent pneumococcal vaccine programs in Canada.
In children aged 6 months to <10 years, the incidence of influenza-like illness associated with respiratory syncytial virus was 7.0 per 100 person-years. The highest burden occurred in older infants and children, which may inform vaccination strategies.
Aim: This study aims to assess rates of antibiotic prescriptions and its determinants in in children with COVID-19 or Multisystem Inflammatory Syndrome (MIS-C).Methods: Children <18 years-old assessed in five Latin Americas countries with a diagnosis of COVID-19 or MIS-C were enrolled. Antibiotic prescriptions and factors associated with their use were assessed. Results: A total of 990 children were included: 921 (93%) with COVID-19, 69 (7.0%) with MIS-C. The prevalence of antibiotic use was 24.5% (n = 243). MIS-C with (OR = 45.48) or without (OR = 10.35) cardiac involvement, provision of intensive care (OR = 9.60), need for hospital care (OR = 6.87), pneumonia and/or ARDS detected through chest X-rays (OR = 4.40), administration of systemic corticosteroids (OR = 4.39), oxygen support, mechanical ventilation or CPAP (OR = 2.21), pyrexia How to cite this article: Yock-Corrales A, Lenzi J, Ulloa-Gutiérrez R, et al.

ABSTRACT. We present the first report in the literature of a child with human metapneumovirus pneumonia who required extracorporeal membrane oxygenation for survival. This was a 3-month-old premature boy from British Columbia, Canada, who developed severe respiratory failure, experienced failure of high-frequency oscillatory mechanical ventilation, and required extracorporeal membrane oxygenation support for 10 days. This case illustrates the importance of including this newly discovered pathogen among the causes of childhood pneumonia.
Since 1941, when Gregg first described the triad of deafness, cataracts and cardiac disease as the classical clinical manifestations of congenital rubella syndrome (CRS), strong efforts have been implemented around the world to achieve effective preventive strategies. In Costa Rica, vaccination against rubella started in 1972 and in 1986, the combined measles, mumps and rubella vaccine was introduced in the national schedule among 1-year-old children. This vaccination strategy shifted the susceptibility to other groups at child-bearing age. To protect this age group, in 2001 Costa Rica implemented a successful national immunization campaign targeting both men and women aged 15-39 years, followed by postpartum vaccination of women who were pregnant when the campaign was implemented. The epidemiological surveillance system of rubella and CRS cases was strengthened and it was integrated with the investigation and notification system of febrile eruptive diseases. We describe the Costa Rican experience, which has led to similar actions in other countries in Latin America. Challenges and strategies in the elimination of rubella and CRS are also discussed.
