Paediatric negative appendicectomy rates at a regional Western Australian Centre: a five-year cohort study.

Background: In acute appendicitis, decision-making around operative intervention for paediatric patients differs from adults due to a higher weight placed on clinical assessment and reduced rates of cross-sectional imaging. In regional settings, non-paediatric emergency doctors, general surgeons, and radiologists usually assess and manage this patient group. Differences have been observed in paediatric negative appendicectomy rates between general and paediatric centres.

Cystic adventitial disease masquerading as ganglion disease: a rare cause of intermittent claudication.

Cystic adventitial disease (CAD) is a rare cause of claudication in which a mucinous cyst forms within the adventitial layer of a blood vessel, most commonly the popliteal artery, resulting in luminal narrowing. This paper presents a case of a man in his mid-50s with unilateral lower limb popliteal artery CAD, which was not initially identified on either duplex ultrasonography or CT angiography. He was successfully treated with surgical resection of the affected segment of the popliteal artery and autologous vein grafting.
