Ferumoxytol-enhanced vascular suppression in magnetic resonance neurography.

Skeletal Radiol 2021 May 7. Epub 2021 May 7.

Department of Radiology and Imaging, Hospital for Special Surgery, New York, NY, USA.

Objective: To evaluate ferumoxytol-enhanced vascular suppression for visualizing branch nerves of the brachial plexus in magnetic resonance (MR) neurography.

Materials And Methods: Signal simulations were performed to determine ferumoxytol's effect on nerve-, fat-, and blood-to-muscle contrast and to optimize pulse sequence parameters. Prospective, in vivo assessment included 10 subjects with chronic anemia who underwent a total of 19 (9 bilateral) pre- and post-infusion brachial plexus exams using three-dimensional (3D), T-weighted short-tau inversion recovery (T-STIR) sequences at 3.

Glenohumeral Arthrodesis Using Pelvic Reconstruction Plates: a Series of 15 Patients.

Ortop Traumatol Rehabil 2021 Apr;23(2):59-64

Artemis Hospital, Gurgaon, Haryana, India.

Background: Glenohumeral joint arthrodesis has become a rare entity due to the introduction of shoulder arthroplasty. It is an excellent salvage procedure for patients with severe shoulder dysfunction, with limited treatment options, indicated for brachial plexus injury, tumour resection, chronic infection, failed prosthetic arthroplasty, or pseudoparalysis of the shoulder due to combined rotator cuff and deltoid deficiency. Shoulder arthrodesis relieves the patient of pain and gives a decent amount of function. Read More

Potential gains: Comparison of a mono-isocentric three-dimensional conformal radiotherapy (3D-CRT) planning technique to hybrid intensity-modulated radiotherapy (hIMRT) to the whole breast and supraclavicular fossa (SCF) region.

J Med Radiat Sci 2021 May 6. Epub 2021 May 6.

Department of Radiation Oncology, Northern Sydney Cancer Centre, Royal North Shore Hospital, St Leonards, NSW, Australia.

Introduction: Until late 2018, standard of practice at the Northern Sydney Cancer Centre (NSCC) for breast and nodal treatment was a conformal mono-isocentric technique. A planning study comparing an existing mono-isocentric three-dimensional conformal radiotherapy (3D-CRT) planning technique to a hybrid intensity-modulated radiotherapy (hIMRT) approach for the whole breast and supraclavicular fossa (SCF) region was undertaken with the aim to improve plan quality by improving dose conformity/homogeneity across target volumes and reducing hotspots outside the target.

Methods: A cohort of 17 patients was retrospectively planned using the proposed hIMRT technique, keeping the same planning constraints as the original treated breast and SCF 3D-CRT plan and normalising the 3D-CRT plans to achieve minimum breast/SCF target coverage to compare organs at risk (OARs).

Quantitative MRI of the brachial plexus shows specific changes in nerve architecture in CIDP, MMN and motor neuron disease.

Eur J Neurol 2021 May 1. Epub 2021 May 1.

Department of Radiology, University Medical Center Utrecht, Utrecht, the Netherlands.

Background: The immunological pathophysiologies of chronic inflammatory demyelinating polyneuropathy (CIDP) and multifocal motor neuropathy (MMN) differ considerably, but neither has been elucidated completely. Quantitative magnetic resonance imaging (MRI) techniques as diffusion tensor imaging, T2 mapping, and fat fraction analysis may indicate in vivo pathophysiological changes in nerve architecture. Our study aims to systematically study nerve architecture of the brachial plexus in patients with CIDP, MMN, motor neuron disease (MND) and healthy controls using these quantitative MRI techniques.

Lumbosacral plexopathy due to pelvic hematoma after extracorporeal membrane oxygenation: A case report.

Medicine (Baltimore) 2021 Apr;100(17):e25698

Department of Neurology, Washington University School of Medicine, Saint Louis, MO.

Rationale: Peripheral nerve injury related to vascular complications associated with extracorporeal membrane oxygenation (ECMO) is perhaps underappreciated. Compared to the well-described central nervous system complications of ECMO, brachial plexopathy and lumbosacral plexopathy have rarely been reported. We report this case to heighten awareness of lumbosacral plexus injury due to pelvic hematoma formation after ECMO. Read More

Risk Factors for Neonatal Brachial Plexus Palsy Attributed to Anatomy, Physiology, and Evolution.

Clin Anat 2021 Apr 27. Epub 2021 Apr 27.

Clinical Radiology & Imaging Science, Riley Hospital for Children, Indiana University School of Medicine, Indianapolis, IN, USA.

The inherent variable anatomy of the neonate and the uniquely-shaped maternal birth canal that is associated with the evolution of human bipedalism, constitute risk factors for neonatal brachial plexus palsy (NBPP). For example, those neonates with a prefixed brachial plexus (BP) are at greater risk of trauma due to lateral neck traction during delivery than those with a normal or postfixed BP. Compared to adults, neonates also have extremely large and heavy heads (high head:body ratio) set upon necks with muscles and ligaments that are weak and poorly developed. Read More
