Increased vertebral canal diameter measured by ultrasonography as a sign of vasculitis in patients with giant cell arteritis.

Introduction: The diagnosis of giant cell arteritis (GCA) by ultrasonography including large vessels, apart from the temporal artery increases the sensibility of the study and informs about the risk of specific complications. However, there is less information about the study of these arteries, whose affection carries higher proportion of severe complications.

Objectives: To describe and analyze the value of the diameter of the cervical vertebral canal of the vertebral artery (VA) as a sign of vertebral vasculitis (VV) related to GCA and estimate the risk of stroke complications.

Perineal protection methods: knowledge and use.

Objective: To analyse the knowledge and use of perineal protection methods during the expulsive stage by health professionals involved in childbirth and whether they correspond to the World Health Organization's recommendations.

Method: This was a cross-sectional descriptive study aimed at health workers involved in births in Spain.

Results: Fifty-seven professionals participated in the study: midwives (47%), gynaecologists (25%), nurse residents (14%) and resident physicians (14%) in obstetrics and gynaecology.

The Application of a System of Eye Tracking in Laparoscopic Surgery: A New Didactic Tool to Visual Instructions.

Laparoscopic surgery is an increasingly used technique, but it requires a high degree of learning, and communication between the operating room crew is considerably difficult. The use of eye tracking has been proposed as a didactic and evaluation tool in several settings, including in laparoscopy in simulators. This study aimed to evaluate the usefulness of the use of eye tracking systems (Tobii glasses 2) in laparoscopic surgery as a didactic and assessment tool to improve communication in the operating room and improve patients' security.
