Defining the microbes in the middle ear and upper respiratory tract that lead to recurrent ear infections – a metagenomic studyUsing the latest sequencing technology to examine the microbial composition of the middle ear & nasopharyngeal region, the site of initial colonization of OM

New findings in the pathogenesis of otitis mediaThis study was the first to concurrently identify middle ear pathogens in both bacterial biofilm and intracellularly in the middle ear mucosa of children and to identify extensive DNA stranding in the MEF from children with AOM

Unraveling the genetics of otitis media: From mouse to human and back againOtitis media (OM) is among the most common illnesses of early childhood, characterised by the presence of inflammation in the middle ear cavity...

Immunogenicity, otitis media, hearing impairment, and nasopharyngeal carriage 6-months after 13-valent or ten-valent booster pneumococcal conjugate vaccines, stratified by mixed priming schedules: PREVIX_COMBO and PREVIX_BOOST randomised controlled trialsAustralian First Nations children are at very high risk of early, recurrent, and persistent bacterial otitis media and respiratory tract infection. With the PREVIX randomised controlled trials, we aimed to evaluate the immunogenicity of novel pneumococcal conjugate vaccine (PCV) schedules.

Australian Aboriginal Otitis-Prone Children Produce High-Quality Serum IgG to Putative Nontypeable Haemophilus influenzae Vaccine Antigens at Lower Titres Compared to Non-Aboriginal ChildrenNontypeable Haemophilus influenzae (NTHi) is the most common bacterial otopathogen associated with otitis media (OM). NTHi persists in biofilms within the middle ears of children with chronic and recurrent OM. Australian Aboriginal children suffer exceptionally high rates of chronic and recurrent OM compared to non-Aboriginal children.

Early detection of hearing loss for infants in Western Australia: Comparison to international benchmarksTo assess the degree to which timely audiological assessment of congenital hearing loss is achieved at our institution - Perth Children's Hospital, Western Australia, and to review cases which breached this timeframe in order to address barriers to timely assessment. The benchmark used to determine timely assessment is that set out by The Joint Committee on Infant Hearing (JCIH) in which diagnostic audiological testing occurs by three months of age for those who do not pass newborn hearing screening.
