SDH deficiency is very common in carotid body paragangliomas: Genetic counseling and testing should be offered to all patients.

Background: Collectively, germline pathogenic variants in succinate dehydrogenase (SDH) genes are the most common cause of hereditary paragangliomas. Loss of immunohistochemical expression of SDHB protein (termed SDH deficiency) occurs whenever there is biallelic inactivation of any SDH gene. We sought to estimate the prevalence of SDH deficiency in patients with carotid body paragangliomas.

Comparative Treatment Outcomes for Idiopathic Subglottic Stenosis: 5-Year Update.

The North American Airway Collaborative (NoAAC) previously published a 3-year multi-institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re-enrolled for 2 additional years and followed using the prespecified published protocol.

Reference rate for post-tonsillectomy haemorrhage in Australia-A 2000-2020 national hospital morbidity database analysis.

This study aims to provide a national benchmark rate of post-tonsillectomy haemorrhage (PTH) in Australia. Using data from Australia's National Hospital Morbidity Database (NHMD) from 1 July 2000 to 30 June 2020, we have conducted a nation-wide population-based study to estimate a reference rate of PTH. Outcomes of interest included the overall rate and time-trend of PTH, the relationship between PTH rates with age and gender as well as the epidemiology of tonsillectomy procedures.

The Indoor Environment and Otitis Media among Australian Children: A National Cross-Sectional Study.

The association between the indoor environment and lifetime prevalence of otitis media (OM) in Australian children was assessed. We analysed data from a cross-sectional study of children, aged 7-11 years, performed in twelve Australian cities during 2007-2008. The main outcome was a parental report of their child's diagnosis with OM by a doctor.

Nasal turbinate mucosal graft for management of contracted anophthalmic socket.

A 67-year-old Caucasian male presented with severe contraction of socket lining 8 years after enucleation, dermis fat graft and successful ocular prosthesis fitting. Following two failed attempts at using amniotic membrane grafts to reform the socket lining, a total socket reconstruction was attempted using a novel nasal turbinate mucosal graft technique. This was performed in a staged fashion with lower fornix reconstruction followed by upper fornix reconstruction 3 months later.
