[Pulmonary thromboembolism as contributing cause of severe respiratory insufficiency in a patient with COVID-19 infection].

We report a case of multiple peripheral pulmonary thromboembolisms in a 69-year-old male hospitalised due to SARS-CoV-2 infection. There were no evident risk factors for pulmonary thromboembolism, the patient had a Wells' score of zero, and the diagnosis only became evident after repeated CT pulmonary angiographies.

[Splash basins are contaminated even during operations in a laminar air flow environment].

Few studies have investigated the potential contamination of splash basins and they have shown very divergent results: contamination ranging from 2.13% to 74% has been reported. This study set out to examine if splash basins used in a laminar air flow (LAF) environment during elective knee and hip arthroplasty constitute an unnecessary risk.

[No contamination of instruments on the trolley during elective arthroplasty].

Infection following arthroplasty is a very serious complication as it has major impact on morbidity and mortality. This study set out to examine if leaving the instruments on the trolley would result in contamination from airborne pathogens during elective hip and knee arthroplasty. We conclude that instruments placed in a laminar airflow field do get contaminated, but further studies with a larger sample size are needed to verify the results.
