A new clinically-relevant rat model of letrozole-induced chronic nociceptive disorders.

Toxicol Appl Pharmacol 2021 08 1;425:115600. Epub 2021 Jun 1.

Université Clermont Auvergne, INSERM U1107, NEURO-DOL, CHU Clermont-Ferrand, Direction de la recherche clinique et de l'innovation, F-63000 Clermont-Ferrand, France. Electronic address:

Among postmenopausal women with estrogen receptor-positive breast cancer, more than 80% receive hormone therapy including aromatase inhibitors (AIs). Half of them develop chronic arthralgia - characterized by symmetric articular pain, carpal tunnel syndrome, morning stiffness, myalgia and a decrease in grip strength - which is associated with treatment discontinuation. Only a few animal studies have linked AI treatment to nociception, and none to arthralgia. Read More

Electrospray Mediated Localized and Targeted Chemotherapy in a Mouse Model of Lung Cancer.

Front Pharmacol 2021 20;12:643492. Epub 2021 Apr 20.

Department of Pulmonary Medicine, University Hospital Bern, Bern, Switzerland.

An advanced stage, centrally localized invasive tumor is a major cause of sudden death in lung cancer patients. Currently, chemotherapy, radiotherapy, laser ablation, or surgical resection if possible are the available state-of-the-art treatments but none of these guarantee remedy or long-term relief and are often associated with fatal complications. Allowing localized chemotherapy, by direct and confined drug delivery only at the tumor site, could be a promising option for preoperative down staging or palliative therapy. Read More

*Microsurgery Centre of Latvia †Faculty of Medicine, Riga Stradiņš University, Latvia, European Union.

Cubital tunnel syndrome (CubTS) is one of the most common compression-traction neuropathy in the upper extremity. The gold standard is simple in situ decompression with revision of potential compression sites through skin incision as small as rationally possible. Properly conducted conservative treatment is more effective in CubTS as opposed to carpal tunnel syndrome. Read More

Using breath δC analysis to determine the effects of dietary carbohydrate and protein on glucose and leucine oxidation at rest in the yellow-rumped warbler (Setophaga coronata).

Comp Biochem Physiol A Mol Integr Physiol 2021 Jun 11;256:110936. Epub 2021 Mar 11.

Department of Biology, Advanced Facility for Avian Research, University of Western Ontario, London, ON N6A5B7, Canada.

Fat is the major fuel for migratory flight of birds, but protein is also catabolized. Flight range could be reduced if protein is used too quickly from muscles and organs, and it is important to understand factors that influence protein catabolism. Previous correlative studies suggested high protein diets may increase protein use in flight, although a wind tunnel study with yellow-rumped warblers (Setophaga coronata) did not support this relationship.

Supraretinacular endoscopic carpal tunnel release: A safe alternative method for treatment of carpal tunnel syndrome.

J Orthop Surg (Hong Kong) 2021 Jan-Apr;29(1):2309499021993407

Department of Orthopaedic Surgery, 12833Iwate Medical University, Idaidori, Yahaba-cho, Shiwa-Gun, Iwate, Japan.

Purpose: Supraretinacular endoscopic carpal tunnel release (SRECTR) is a technique in which an endoscope is inserted superficial to the flexor retinaculum through a subcutaneous tunnel.

Ventricular Assist Device-Specific Infections.

J Clin Med 2021 Jan 25;10(3). Epub 2021 Jan 25.

Department of Cardiothoracic Surgery, The Alfred Hospital, Monash University, Prahran, Melbourne, VIC 3004, Australia.

Ventricular assist device (VAD)-specific infections, in particular, driveline infections, are a concerning complication of VAD implantation that often results in significant morbidity and even mortality. The presence of a percutaneous driveline at the skin exit-site and in the subcutaneous tunnel allows biofilm formation and migration by many bacterial and fungal pathogens. Biofilm formation is an important microbial strategy, providing a shield against antimicrobial treatment and human immune responses; biofilm migration facilitates the extension of infection to deeper tissues such as the pump pocket and the bloodstream.

Novel Reconstruction of Complex Central Venous Occlusion Using Supraclavicular Stent Graft in Hemodialysis Patients.

Ann Vasc Surg 2021 May 26;73:185-196. Epub 2020 Dec 26.

DFW Vascular Group, Dallas, TX; Surgery, Methodist Dallas Medical Center, Dallas, TX; TCU School of Medicine, Ft. Worth, TX. Electronic address:

Background: Subclavian vein and brachiocephalic vein occlusions are challenging problems in dialysis patients with ipsilateral upper extremity (UE) vascular access or in need of one. HeRO grafts (Hemodialysis Reliable Outflow, Merit Medical Systems, Inc, South Jordan, UT) have been used to manage such occlusions but patients with chronic hypotension treated with HeRO graft may have threatened patency. We describe an alternative technique using a supraclavicular stent graft to reconstruct the venous outflow, evaluate outcomes of this procedure, and discuss its role in complex hemodialysis patients.

Ulnar neuropathy at the elbow.

Orthop Traumatol Surg Res 2021 02 13;107(1S):102754. Epub 2020 Dec 13.

Sorbonne Université, Service de chirurgie orthopédique et traumatologique-SOS mains, Hôpital Saint-Antoine, Centre de Recherche Saint-Antoine UMR_S938 INSERM, 184, rue du Faubourg Saint-Antoine, 75012 Paris, France. Electronic address:

At the elbow, the ulnar nerve (UN) may be the site of a static compression (by the cubital tunnel retinaculum and Osborne's ligament between the two heads of the flexor carpi ulnaris), or a dynamic compression, especially when the nerve is unstable (subluxation/dislocation outside the ulnar groove). The clinical basis for the diagnosis of ulnar neuropathy involves looking for subjective and objective signs of sensory and/or motor deficit in the ulnar nerve's territory in the hand, a pseudo-Tinel's sign, and doing manipulations to provoke UN irritation. The diagnosis is confirmed by electromyography and ultrasonography. Read More
