Stéphane Urcun, Pierre-Yves Rohan, Wafa Skalli, Pierre Nassoy, Stéphane P.A. Bordas, Giuseppe Sciumè,

Abstract Spheroids encapsulated within alginate capsules are emerging as suitable in vitro tools to investigate the impact of mechanical forces on tumor growth since the internal tumor pressure can be retrieved from the deformation of the capsule. Here we focus in particular on the Cellular Capsule Technology (CCT). We show ... Read more >>

Microstructural characterization of annulus fibrosus by ultrasonography: a feasibility study with an in vivo and in vitro approach.

Tristan Langlais, Pierre Desprairies, Raphael Pietton, Pierre-Yves Rohan, Jean Dubousset, Judith R Meakin, Peter C Winlove, Raphael Vialle, Wafa Skalli, Claudio Vergari,

The main function of the intervertebral disc is biomechanical function, since it must resist repetitive high loadings, while giving the spine its flexibility and protecting the spinal cord from over-straining. It partially owes its mechanical characteristics to the lamellar architecture of its outer layer, the annulus fibrosus. Today, no non-invasive ... Read more >>

Assessing 3D paediatric foot morphology using low-dose biplanar radiography: Parameter reproducibility and preliminary values.

Virginie Rampal, Pierre-Yves Rohan, Rebekah Saksik, Philippe Wicart, Wafa Skalli,

BACKGROUND:The physical examination and weight-bearing radiography are the two main available methods for assessing the feet and lower limbs. The anatomy and function of these two structures interact with each other. These two assessment methods are affected by subjectivity and projection bias. Low-dose biplanar radiography (LDBR) is now a promising ... Read more >>

Development and evaluation of a new methodology for the fast generation of patient-specific Finite Element models of the buttock for sitting-acquired deep tissue injury prevention.

Aurélien Macron, Hélène Pillet, Jennifer Doridam, Alexandre Verney, Pierre-Yves Rohan,

The occurrence and management of Pressure Ulcers remain a major issue for patients with reduced mobility and neurosensory loss despite significant improvement in the prevention methods. These injuries are caused by biological cascades leading from a given mechanical loading state in tissues to irreversible tissue damage. Estimating the internal mechanical ... Read more >>

Feasibility of sub-dermal soft tissue deformation assessment using B-mode ultrasound for pressure ulcer prevention.

J Doridam, A Macron, C Vergari, A Verney, P-Y Rohan, H Pillet,

Pressure Ulcer (PU) prevention remains a main public health issue. The physio-pathology of this injury is not fully understood, and a satisfactory therapy is currently not available. Recently, several works suggested that mechanical strains are responsible of deformation-induced damage involved in the initiation of Deep Tissue Injury (DTI). A better ... Read more >>

Pierre-Yves Rohan, Antoine Perrier, Mira Ramanoudjame, Jérôme Hausselle, Henri Lelièvre, Raphael Seringe, Wafa Skalli, Philippe Wicart,

The initial assessment and postoperative monitoring of patients with various abnormalities of the foot in clinical routine practice is primarily based on the analysis of radiographs taken in the weightbearing position. Conventional x-ray imaging, however, only provides a 2-dimensional projection of 3-dimensional (3D) bony structures, and the clinical parameters assessed ... Read more >>

A T Foran, G J Nason, P Rohan, G M Keane, S Connolly, N Hegarty, D Galvin, K J O’Malley,

Suprapubic catheter insertion and exchange is a common urological procedure, but it is not without risks and complications. While bowel perforation is a recognised complication at suprapubic catheter insertion, it is not commonly reported at suprapubic catheter exchange. We report our experience of recognition, diagnosis and subsequent successful management of ... Read more >>

Prediction of the biomechanical effects of compression therapy on deep veins using finite element modelling.

Pierre-Yves Rohan, Pierre Badel, Bertrand Lun, Didier Rastel, Stéphane Avril,

Clinicians generally assume that Medical Compression Stockings (MCS) work by reducing vein luminal diameter and, in this way, help to prevent blood pooling. Conflicting results have been reported however in the case of lower leg deep veins which call into question this hypothesis. The purpose of this contribution is to ... Read more >>
