Randomized Controlled Trial Comparative StudyRandomised comparison of complications from three different permanent central venous access systems.
We present a prospective randomised trial comparing complications from three different permanent central venous access systems (PCVAS). ⋯ The polyurethane catheters that ruptured more often had a larger diameter and a thicker wall than the other polyurethane catheters, and were probably subjected to greater shearing between the clavicle and the first rib. Silicone catheters, although thicker and of larger diameter than the two other catheters, seemed more resistant to shearing.

Transient global amnesia (TGA) is characterised by the sudden occurrence of amnesia while lacking other neurological symptoms. Complete remission occurs within 24 hours. The pathogenesis remains unknown. The objective of this study was to evaluate the prevalence of TGA in a primary referral hospital in Uster, Switzerland and examine the accuracy of the diagnostic procedure and outcome. ⋯ TGA is a syndrome of which emergency physicians should be aware. The diagnosis is made clinically and the prognosis is good, although relapses may occur. Missed diagnoses may lead to uncertainty in patients and their relatives.
