Introduction: Postoperative hypocalcaemia is common after thyroidectomy. This study aimed to evaluate whether a standardised post-thyroidectomy protocol using prophylactic calcium and calcitriol reduces hypocalcaemia incidence after total thyroidectomy in children and adolescents.

Methods: A cohort children and adolescents ≤18 years of age undergoing total thyroidectomy between January 2016 and October 2022 in one institution were retrospectively identified and divided into pre-protocol and post-protocol groups.

Physical activity (PA) during childhood and adolescence is important for the accrual of maximal peak bone mass. The precise dose that benefits bone remains unclear as methods commonly used to analyze PA data are unsuitable for measuring bone-relevant PA. Using improved accelerometry methods, this study identified the amount and intensity of PA most strongly associated with bone outcomes in 11-12-year-olds.

Background: Medication use in pregnancy is common; however, it is unknown if clinical practice guideline (CPG) prescribing recommendations referred to in Australia at the state, national and international level are consistent.

Aims: This systematic review aimed to: (1) identify sources of CPGs that inform prescribing during pregnancy in Australia; (2) assess CPG quality; and (3) evaluate variation within CPG recommendations for medication use in three common conditions in pregnancy: prophylactic antibiotics following premature rupture of membranes (PROM) at term, antidepressants in pregnancy and metformin in gestational diabetes mellitus (GDM).

Materials And Methods: A literature search was conducted across PubMed, Scopus and EMBASE databases.

Whilst the aetiology is still being investigated; there is evidence that genetic predisposition may be a risk factor for the development of myocarditis. Furthermore, hormones are thought to contribute to sex-specific differences in myocarditis, skewed toward a larger risk in adolescent males.

Article Synopsis
  • X-linked hypophosphataemia (XLH) is a genetic condition leading to rickets, with prevalence estimates between 1 in 20,000 to 1 in 200,000; study in Australia and New Zealand aimed to better understand its prevalence and characteristics.
  • A total of 75 cases in Australia and 18 in New Zealand were identified, revealing a minimum estimated prevalence of 1.33 per 100,000 in Australia and 1.60 per 100,000 in New Zealand, but many cases go undiagnosed until after age 2, impacting treatment and outcomes.
  • Common symptoms include leg bowing, bone pain, and short stature, with significant complications like nephrocalc
