Streptococcus dysgalactiae subspecies equisimilis and Streptococcus pyogenes share skin and throat niches with extensive genomic homology and horizontal gene transfer possibly underlying shared disease phenotypes.

Research

The changing phenotype of coronarvirus disease 2019 (COVID-19) may quickly render guideline-recommended interventions obsolete. We developed a 40-question clinician survey in consultation with the Australasian COVID-19 Trial site investigators. The survey was designed to assess clinician perceptions of the current treatment strategies and future research priorities in the management of non-critically ill patients admitted to hospital with SARS-CoV-2 infection.

The structure and function of infant skin is not fully developed until 34 weeks of gestation, and this immaturity is associated with risk of late-onset sepsis (LOS). Topical coconut oil improves preterm-infant skin integrity and may reduce LOS. However, data on early-life skin-microbiome succession and potential effects of emollient skin care in preterm infants are scarce.

Itraconazole remains a first-line antifungal agent for certain fungal infections in children, including allergic bronchopulmonary aspergillosis (ABPA) and sporotrichosis, but poor attainment of therapeutic drug levels is frequently observed with available oral formulations. A formulation of 'SUper BioAvailability itraconazole' (SUBA-itraconazole; Lozanoc®) has been developed, with adult studies demonstrating rapid and reliable attainment of therapeutic levels, yet paediatric data are lacking.

Research

Group A Streptococcus (Strep A) is an important cause of mortality and morbidity globally. This bacterium is responsible for a range of different infections and post-infectious sequelae. Summarising the current knowledge of Strep A transmission to humans will address gaps in the evidence and inform prevention and control strategies. The objective of this study is to evaluate the modes of transmission and attack rates of group A streptococcal infection in human populations.

We have demonstrated the potential use of Bayesian Networks in improving antibiotic selection for children with osteomyelitis

Research

During a pandemic when hospitals are stretched and patients need isolation, the role of hospital-in-the-home (HITH) providing acute medical care at home has never been more relevant. We aimed to define and address the challenges to acute home care services posed by the COVID-19 pandemic.

Research

We have closely followed the international literature about severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) transmission dynamics in children (aged 0–18 years).2 Evidence‐informed discussion about school attendance in the context of COVID‐19 is a high priority and this complex subject requires weighted expert review of the literature to accurately inform policy. As paediatricians and infectious diseases specialists, we wish to highlight important considerations when interpreting the available data.

Research

The incidence of neonatal varicella has decreased dramatically since the introduction of the varicella vaccination. Although the varicella zoster virus is often associated with a mild infection, it may cause severe morbidity and mortality, particularly in the neonatal period and immunocompromised hosts. We report a case of neonatal varicella acquired from maternal zoster in a mother on biological immunosuppressive therapy.
