Background: Abdominal tuberculosis (ATB) poses a significant diagnostic, management, and resource challenge. In Australia, an increasing number of tuberculosis (TB) cases are being reported, and we describe our experience of ATB in an Australian tertiary institution.
Methods: All diagnosed cases of tuberculosis (TB) at the Royal North Shore tertiary hospital campus of the University of Sydney are entered prospectively into a central registry. Cases of ATB encountered between September 1991 and November 2011 were identified and retrospectively reviewed.
Results: In all, 841 cases of TB were identified, of which 20 were abdominal (2.4 %). Median age at presentation was 34 years (range: 22-79 years), and 55 % of patients were women. None of the patients were born in Australia and 11 patients were of South Asian origin. The most common presenting symptom was abdominal pain (65 %). Diagnosis was based primarily on histology (90 % sensitivity), and the sensitivity of PCR analysis in this series was low (44 %). Eleven of the patients required laparoscopy or laparotomy. 40 % of cases involved the peritoneum, and disease was also seen in solid organs (liver, spleen, pancreas, adrenal gland) and bowel (esophagus, small bowel, colon).
Conclusions: In our local experience ATB was seen exclusively in the immigrant population. The presentation of ATB varies greatly, necessitating a high index of suspicion within the context of abdominal symptoms in high-risk groups. The role of surgical involvement is indispensable for both diagnosis and management of ATB-related complications. Surgeons should remain mindful of the diagnosis in an age of increasing worldwide incidence.

Study of Children Aged Under 2 Years Admitted With RSV at Four Australian Hospitals [2021-2022].
J Paediatr Child Health
January 2025
WHO Collaborating Centre for Reference and Research on Influenza, VIDRL, Doherty Institute, Melbourne, Victoria, Australia.
Aims: Primary aim was to review severe acute respiratory infections (SARI) hospitalisations caused by respiratory syncytial virus (RSV) in children aged < 2 years in paediatric hospitals in Australia. Secondary aims included RSV subtyping, assessing RSV seasonality and contributing to the World Health Organisation's RSV surveillance programme.
Methods: We prospectively reviewed the medical records of children (< 2 years of age) with a confirmed SARI who were admitted to one of four major Australian paediatric hospitals and had a respiratory sample analysed by Polymerase Chain Reaction (PCR).
Promoting effective transitions: Primary school social-emotional competencies predict secondary school reading and numeracy achievement.
Br J Educ Psychol
January 2025
School of Psychology and Counselling, Queensland University of Technology (QUT), Brisbane, Queensland, Australia.
Background: The transition from primary to secondary school presents a challenging developmental milestone which often marks a decline in academic performance. Social-emotional skills are recognized as fundamental to academic success but longitudinal research is needed to determine the extent of their association over this transition period.
Aim: This study sought to determine the association between self-reported social-emotional competencies of students in their final year of primary school (Year 6; age ~11 years) and reading and numeracy performance in their first year of secondary school (Year 7; age ~12 years).
Transitioning to high-sensitivity troponin: 1-year mortality outcomes in patients with suspected acute coronary syndrome presenting to emergency departments.
Heart
January 2025
Cardiovascular Epidemiology Research Centre, School of Population and Global Health, The University of Western Australia, Perth, Western Australia, Australia.
Background: Switching from a conventional to a high-sensitivity cardiac troponin (hs-cTn) assay enables detection of smaller amounts of myocardial damage, but the clinical benefit is unclear. We investigated whether switching to a hs-cTnI assay with a sex-specific 99th centile diagnostic threshold was associated with lower 1-year death or new myocardial infarction (MI) in patients with suspected acute coronary syndrome (ACS).
Methods: This pre-post study included nine tertiary hospitals in Australia.
The "CUPCAKE" technique (coiled underlying pseudoaneurysm contained by a woven endobridge device) for treating intracranial aneurysms with atypical morphology.
Interv Neuroradiol
January 2025
Department of Interventional Neuroradiology, Austin Health, Heidelberg, Melbourne, Australia.
Background: Intrasaccular flow diversion using the woven endobridge device (WEB; MicroVention, Aliso Viejo, CA, USA) for the treatment of intracranial aneurysms has demonstrated large scale safety and efficacy. However, limitations arise from its structural configuration, restricting its application to specific aneurysm sizes and shapes.
Technique Overview: We introduce the CUPCAKE technique, a combination of conventional coiling followed by WEB intrasaccular flow disruption in select cases of atypical aneurysms with technically challenging morphology not typically treatable by WEB alone.
Cancer metastasis to the upper gastrointestinal tract-a case series.
J Gastrointest Oncol
December 2024
Medical Oncology Department, The Canberra Hospital, Canberra, ACT, Australia.
Background: Metastasis of non-gastrointestinal (non-GI) cancers to the upper GI tract is a rare occurrence, with limited cases reported in the literature. Recognising this type of metastasis is crucial, as it presents unique diagnostic and therapeutic challenges. This case series adds to the literature by discussing seven rare cases of non-GI cancer metastasising to the upper GI tract, emphasising the complications and clinical manifestations.
