Popliteal artery aneurysms (PAAs) comprise up to 85 per cent of all peripheral aneurysms. Few longitudinal studies track their progression. This study aimed to track the growth of asymptomatic PAAs in a hospital-based ultrasound service, and compare models of aneurysm growth. ⋯ Growth rates of PAA were heterogeneous but were optimally predicted by multilevel modelling. Patients with an existing AAA may have faster PAA progression than those without.

The association between risk of pancreatic cancer and a dilated main pancreatic duct (MPD) in intraductal papillary mucinous neoplasm (IPMN) is debated. The aim of this study was to assess the role of MPD size in predicting pancreatic cancer in resected IPMNs and those kept under surveillance. ⋯ In patients under surveillance, a dilated MPD alone was not associated with an increased incidence of malignancy in IPMN.

Systematic review of the safety and efficacy of osseointegration prosthesis after limb amputation.
Osseointegration, an approach for direct skeletal attachment of a prosthesis to an amputated limb, may address many of the problems associated with socket prostheses. The safety of osseointegration remains uncertain. The aim of this study was to summarize evidence on functional and clinical outcomes, as well as adverse effects of osseointegration for patients with a limb amputation. ⋯ Osseointegration after limb amputation improves prosthetic use, comfort when sitting, walking ability, mobility, gait and quality of life. However, it is associated with an increased risk of soft tissue infection.
