The differential diagnosis of an acute liver injury is extremely broad and can often change following initial investigations. We describe the case of a 54-year-old woman whose liver function derangement was initially attributed to alcohol excess, but in fact turned out to be cardiac in origin. We describe the underlying mechanisms and features of cardiac-related liver injury, and how the pattern of liver tests alongside appropriate imaging can help obtain the diagnosis.

Contact tracing is central to the public health response to COVID-19, but the approach taken has received criticism for failing to make enough of an impact on disease transmission. We discuss what can be learned from contact tracing in other infections, and how the natural history of COVID-19 should shape the strategies used.

Abdominal aorta aneurysm rupture is a potential lethal complication and is surgical emergency. In addition, formation of a portal vein and abdominal aorta fistula is a possible, very rare complication that enforces complicated surgical management. Multidetector computed tomography with bolus injection tracking and multiplanar reconstruction is the modality of choice in revealing an aortic rupture and its potential complications.

Lessons of the month: ANCA-associated vasculitis - granulomatosis with polyangiitis: 'the great mimic'.
We describe the case of a 61-year-old woman who presented with progressive respiratory symptoms and imaging demonstrating multiple opacities in the right lung with hilar and mediastinal lymphadenopathy suggestive of multifocal adenocarcinoma. Subsequent biopsies were consistent with focal changes of organising pneumonia (OP) and no evidence of malignancy. She was treated with steroids for cryptogenic OP with limited response. ⋯ There was ongoing concern that clinical findings represented disseminated malignancy. Following further investigation and multidisciplinary respiratory and rheumatology review, a diagnosis of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) - granulomatosis with polyangiitis (GPA) was confirmed. The case highlighted the multisystem nature of GPA with unusual dural and large vessel aortic and pulmonary trunk involvement.

Ulcerative colitis is a relapsing and remitting disease that is increasing in incidence and prevalence. Management aims to achieve rapid resolution of symptoms, mucosal healing and improvement in a patient's quality of life. 5-aminosalicylate acid medications remain the first-line treatment for mild to moderate disease. ⋯ Importantly, despite best medical therapy, surgery may be required in a proportion of patients. The future will likely see an array of new therapeutic options for those with ulcerative colitis with the potential for a more personalised treatment approach.
