[Return to work: challenges and opportunities for the primary care physician].

Return to work is at the crossroads of complex medical, legal, economic and social concepts and involves a multitude of stakeholders who are often far removed from the reality of care in the medical practice. This article presents some basic concepts on return to work and explores some good practice guidelines. It also describes the role and limits of the occupational physician in the company and mentions possible areas of collaboration with social insurers and employers.

Increased susceptibility of arterial tissue to wire perforation with the application of high-frequency mechanical vibrations.

High-frequency mechanical vibrations (20-50 kHz), delivered via small diameter flexible wire waveguides represent a minimally invasive technology for the treatment of chronic total occlusions and in other tissue ablation applications. Tissue disruption is reported to be caused by repetitive mechanical contact and cavitation. This work focuses on the effects of vibrating wire waveguides in contact with arterial tissue.

[A look at gender in research. A qualitative analysis].

Objective: To find out the views of a group of national women experts on gender and health on the key elements to consider in research with a gender perspective, and what are the resistance barriers when trying to include this perspective in the research.

Design: Meeting of a group of experts. Two types of analysis, discourse analysis, analysis of group outputs were used.

High power, low frequency ultrasound: meniscal tissue interaction and ablation characteristics.

This study evaluates high power low frequency ultrasound transmitted via a flat vibrating probe tip as an alternative technology for meniscal debridement in the bovine knee. An experimental force controlled testing rig was constructed using a 20 kHz ultrasonic probe suspended vertically from a load cell. Effect of variation in amplitude of distal tip displacement (242-494 μm peak-peak) settings and force (2.

Ablation of chronic total occlusions using kilohertz-frequency mechanical vibrations in minimally invasive angioplasty procedures.

Certain minimally invasive cardiology procedures, such as balloon angioplasty and stent implantation, critically require that the site of an arterial blockage be crossed by an intraluminal guidewire. Plaques resulting in near or totally occluded arteries are known as chronic total occlusions, and crossing them with conventional guidewires is a significant challenge. Among the most promising proposed solutions is the delivery of high-power, low-frequency ultrasonic vibrations to the occlusion site via an intraluminal wire waveguide.
