Thierry Corcos

Catheter Cardiovasc Interv 2018 Dec 11. Epub 2018 Dec 11.

Department of Cardiology, American Hospital of Paris and Hôpital Foch, Suresnes, France.

Since its introduction by Lucien Campeau three decades ago, percutaneous radial artery approach at the forearm has been shown to provide advantages over the femoral approach and has become the standard approach for coronary angiography and intervention. Though infrequent, vascular complications still remain, mainly radial artery occlusion. Therefore, a more distal radial approach at the snuffbox or at the dorsum of hand has been suggested, initially by anethesiologists for perioperative patient monitoring, and more recently by Babunashvili et al.

Isolation and Characterization of Different Mesenchymal Stem Cell Populations from Rat Femur.

Methods Mol Biol 2019 ;1916:133-147

Division of Endocrinology, Department of Medicine, Faculty of Medicine and Health Sciences, Stellenbosch University, Cape Town, South Africa.

Purified mesenchymal stem cells (MSCs) may be used for a multitude of applications, from the study of biological processes such as cell division and coordinated gene expression to tissue engineering and regenerative medicine. However, although highly similar, MSCs isolated and purified from different tissues may be biologically different in the ability of the cells to respond to environmental cues that instigate and propagate changes in cell fate such as differentiation, proliferation, apoptosis, and senescence. Selecting which MSC subtype to study may therefore profoundly influence the outcome of the investigation. Read More

The Tutankhamun Technique in Hip Arthroscopy.

Arthrosc Tech 2018 Nov 15;7(11):e1167-e1171. Epub 2018 Oct 15.

Laredo Arthroscopy Center, Laredo, Texas, U.S.A.

Hip arthroscopy has been increasing tremendously in the past decade and is a very common surgical procedure to repair femoroacetabular impingement. To access the hip joint, distraction is mandatory to treat intra-articular disorders such as labral tears, cartilage loose bodies, and ligamentum teres tears and to evaluate the condition of the femoral head and acetabular cartilage. To distract the hip, counterdistraction is needed, and this is achieved with placement of a bulky and cushioned perineal post. Read More

Concomitant Arthroscopy With Labral Reconstruction and Periacetabular Osteotomy for Hip Dysplasia.

Arthrosc Tech 2018 Nov 15;7(11):e1141-e1147. Epub 2018 Oct 15.

American Hip Institute, Westmont, Illinois, U.S.A.

In the setting of true hip dysplasia, the high prevalence of intra-articular pathology may lead to recurrent symptoms and failure after periacetabular osteotomy (PAO). Femoral neck osteochondroplasty, microfracture, removal of loose bodies, and labral repair are examples of procedures that are performed with concomitant arthroscopy. When damage to the labrum is too severe to repair, reconstruction instead of extensive debridement before PAO can be more effective in restoring the labral seal to maintain joint lubrication and chondral protection.

Invasive Hemodynamic Monitoring of Aortic and Pulmonary Artery Hemodynamics in a Large Animal Model of ARDS.

J Vis Exp 2018 Nov 26(141). Epub 2018 Nov 26.

Universitatsklinikum Hamburg-Eppendorf.

One of the leading causes of morbidity and mortality in patients with heart failure is right ventricular (RV) dysfunction, especially if it is due to pulmonary hypertension. For a better understanding and treatment of this disease, precise hemodynamic monitoring of left and right ventricular parameters is important. For this reason, it is essential to establish experimental pig models of cardiac hemodynamics and measurements for research purpose. Read More

Background: To determine whether transradial access (TRA) is as safe and efficacious as transfemoral access (TFA) in patients undergoing left main percutaneous coronary intervention (PCI).

Patients And Methods: A systematic search of Medline, Embase, and the Cochrane Central Register of Controlled Trials databases was performed to indentify studies comparing TRA with TFA in left main PCI. The primary efficacy outcome was the incidence of major adverse cardiac events (MACEs) and the primary safety outcome was bleeding. Read More

Cemented Femoral Component Use in Hip Arthroplasty.

J Am Acad Orthop Surg 2018 Dec 7. Epub 2018 Dec 7.

From Dunedin School of Medicine, University of Otago, Dunedin, New Zealand (Dr. Scanelli), the Shenandoah Valley Orthopedics, Fishersville, VA (Dr. Reiser), Riverside Orthopedics, Williamsburg, VA (Dr. Sloboda), and Virginia Tech Carilion School of Medicine, Roanoke, VA (Dr. Moskal).

Elderly patients undergoing both elective and nonelective hip arthroplasty contribute markedly to health care spending, and the current aging population is likely to require even more resources. Several national joint replacement registries show a lower risk of revision surgery in patients older than 75 years who received cemented femoral components compared with cementless implants for primary total hip arthroplasty. Despite a higher incidence of early periprosthetic femoral fracture, noncemented femoral components are being used with increasing frequency in elderly patients worldwide. Read More
