Improved Uptake of Vaccinations in Children With Adverse Events Following Immunization After Specialist Immunization Service Intervention in an Australian Pediatric Hospital.

Background: Adverse Events Following Immunization (AEFI) have significant implications for public health, potentially leading to decreased immunization rates and vaccine hesitancy. Understanding the characteristics and outcomes of children experiencing AEFI is crucial for effective intervention strategies and informed decision-making. This study aimed to describe the diverse range of AEFI presentations, identify common referral sources and assess factors influencing vaccination uptake following specialist consultation.

Live Vaccine and Varicella Postexposure Prophylaxis in Pediatric Liver Transplant Recipients: A Survey of Practice in Australia and New Zealand.

Background: Administration of live vaccines following liver transplant (LT) has historically not been recommended due to concerns regarding risk of vaccine-attenuated disease. However, there is evidence suggesting that in select transplant recipients live vaccinations can be administered safely. Studies in other regions have indicated that despite this evidence many clinicians remain hesitant to administer live vaccinations.

A novel drive-through approach to vaccination of children and young people with neurodevelopmental disability.

Disparities in preventative health care likely contribute to comorbidities associated with neurodevelopmental disability. These comorbidities are risk factors for poor outcomes of COVID-19, making COVID-19 vaccination a priority for this population. In mid-2021, the Australian Technical Advisory Group (ATAGI) recommended the COVID-19 vaccination rollout include children and young people at risk of severe COVID-19 associated disease.

Inborn Errors of Immunity in Children With Invasive Pneumococcal Disease: A Multicenter Prospective Study.

Background: In settings with universal conjugate pneumococcal vaccination, invasive pneumococcal disease (IPD) can be a marker of an underlying inborn error of immunity. The aim of this study was to determine the prevalence and characterize the types of immunodeficiencies in children presenting with IPD.

Methods: Multicenter prospective audit following the introduction of routinely recommended immunological screening in children presenting with IPD.

A multicentre, retrospective audit of fosfomycin use for urinary tract infections in Australian children and adolescents.

Background: Urinary tract infections (UTIs) due to MDR organisms are increasingly common. The lack of paediatric data on efficacious antibiotics makes UTI treatment particularly challenging. Data on the efficacy of fosfomycin use for UTI in children are variable.

Immunogenicity and safety of vaccination in children with paediatric rheumatic diseases: a scoping review.

Children with paediatric rheumatic diseases (PRDs) are at increased risk of vaccine-preventable disease. Safe and effective vaccination is central to preventive care in PRD patients; however, uncertainty surrounding immunogenicity and safety has contributed to suboptimal vaccination. The aim of this study was to evaluate treatment effect on immunogenicity to vaccination in PRD patients and assess vaccine safety, specifically adverse events following immunisation (AEFI) and disease flare.

The impact of a multidisciplinary care package for vaccination in needle phobic children: An observational study.

Aims: Children with severe needle phobia find vaccination extremely distressing and can remain unvaccinated, which puts them at an increased risk of contracting and transmitting vaccine preventable disease. Referral to a specialist or hospital service may occur when they cannot be safely vaccinated in the community, but engagement of allied health services can be inconsistent. The aim of the study was to assess the impact of a multidisciplinary, consumer-oriented model of care on vaccinations for needle phobic children.

Status epilepticus following vaccination in children aged ≤24 months: A five-year retrospective observational study.

Background: Status epilepticus is associated with significant morbidity and mortality. While vaccine-proximate status epilepticus (VP-SE) has rarely been associated with cases of Dravet syndrome, it is not known whether VP-SE differs clinically from non-vaccine proximate status epilepticus (NVP-SE).

Methods: Medical records of children aged ≤24 months, presenting to one of five Australian tertiary pediatric hospitals with their first episode of status epilepticus from 2013 to 2017 were identified using ICD-coded discharge diagnoses.

Gram-negative neonatal sepsis in low- and lower-middle-income countries and WHO empirical antibiotic recommendations: A systematic review and meta-analysis.

Background: Neonatal sepsis is a significant global health issue associated with marked regional disparities in mortality. Antimicrobial resistance (AMR) is a growing concern in Gram-negative organisms, which increasingly predominate in neonatal sepsis, and existing WHO empirical antibiotic recommendations may no longer be appropriate. Previous systematic reviews have been limited to specific low- and middle-income countries.

Optimising immunisation in children with 22q11 microdeletion.

Background: The condition known as 22q11 microdeletion syndrome has a broad phenotypic spectrum, with many affected individuals experiencing mild-to-moderate immunodeficiency. Currently, there are significant variations in live vaccine practices and immunological testing prior to live vaccine administration due to safety concerns and limited established guidelines.

Methods: Queensland Children's Hospital (QCH) Child Development Unit, offers a state-wide 22q11 microdeletion clinic.

Progress and Pitfalls in the Quest for Effective SARS-CoV-2 (COVID-19) Vaccines.

There are currently around 200 SARS-CoV-2 candidate vaccines in preclinical and clinical trials throughout the world. The various candidates employ a range of vaccine strategies including some novel approaches. Currently, the goal is to prove that they are safe and immunogenic in humans (phase 1/2 studies) with several now advancing into phase 2 and 3 trials to demonstrate efficacy and gather comprehensive data on safety.

In utero exposure to biologic disease-modifying anti-rheumatic drugs and effects to the infant: infectious complications, vaccine response, and safety of live vaccine administration.

Biologic disease-modifying anti-rheumatic drugs (bDMARDS) are increasingly used in clinical practice for a variety of conditions. Due to concerns surrounding persistence of drug levels and resulting immunosuppression, current case reports recommend against live vaccine administration in the first year of life for an infant exposed to perinatal bDMARDS. As a result, this significantly impacts receipt of rotavirus vaccination, a vaccine recommended in many countries' national immunization program.

Pediatric Neuroschistosomiasis: A Case Report and Review of the Literature.

Neuroschistosomiasis is a rare but severe manifestation of Schistosoma infection. Diagnosis is challenging and surgical biopsy is often required to confirm diagnosis and exclude malignancy. We present a pediatric case of presumed pseudotumoral cerebral schistosomiasis secondary to Schistosoma mansoni with an excellent therapeutic response to empirical praziquantel and corticosteroid treatment.

Improved Clinical Outcome After Treatment of Mycobacterium abscessus Complex Pulmonary Disease in Children With Cystic Fibrosis.

Background: Mycobacterium abscessus complex pulmonary disease (M. abscessus PD) in cystic fibrosis (CF) is challenging to treat. Current guideline therapeutic regimens involving an intensive phase of intravenous (IV) antibiotics followed by a consolidation phase of inhaled and oral antibiotics are not evidence-based.

Non-typhoidal Salmonella infections in children: Review of literature and recommendations for management.

Non-typhoidal Salmonellae are a major cause of infectious diarrhoea worldwide and can cause invasive diseases, including bacteraemia, meningitis and osteomyelitis. Young or immunocompromised children and those with underlying conditions such as sickle cell disease are particularly vulnerable to invasive disease. There has been an increase in the rate of resistant non-typhoidal Salmonella, which is associated with invasive disease and hospitalisation.

Tetanus in New Zealand children: Intensive care management of a vaccine preventable disease.

Aim: To review management of children admitted with tetanus to Starship Children's Hospital from 2000 to 2013.

Methods: Retrospective chart review of children aged 0-15 years admitted to Starship Children's Hospital with tetanus from 2000 to 2013. Follow-up of immunisation status was via the National Immunisation Register and/or phone contact with patient's primary health care provider.

Prospective surveillance of hospitalisations associated with varicella in New Zealand children.

Aim: Varicella is a vaccine-preventable disease not notifiable in New Zealand (NZ), and varicella vaccine is not funded in the National Immunisation Schedule (NIS). Hospitalisations can occur because of bacterial secondary infection and other complications, which can result in long-term sequelae. Varicella may not be acknowledged in discharge coding when complications occur weeks after infection.

Varicella in a Paediatric Intensive Care Unit: 10-year review from Starship Children's Hospital, New Zealand.

Aims: Varicella is now a vaccine-preventable disease but is generally considered benign, making it a low priority for a funded universal immunisation scheme. We aimed to increase the knowledge of the severity, morbidity and mortality caused by varicella, by a review of cases requiring paediatric intensive care in New Zealand where vaccine is available but not funded.

Methods: This is a retrospective chart review of children admitted to the paediatric intensive care unit (PICU) over a 10-year period (July 2001-July 2011) identified from the PICU database with a primary or secondary code for varicella.
