Distal Stimulation Site at the Medial Tibia for Saphenous Nerve Somatosensory Evoked Potentials (DSn-SSEPs) in Lateral Lumbar Spine Procedures.

Neurodiagn J 2021 May 5:1-14. Epub 2021 May 5.

Axis Neuromonitoring, Richardson, Texas.

Lateral lumbar interbody fusion procedures are performed with multimodality neuromonitoring of the femoral nerve to prevent lumbosacral plexus and peripheral nerve injury from positioning, dilation, retraction, and hardware implantation. The integrity of the femoral nerve can be continuously assessed during these procedures by Somatosensory Evoked Potentials of the Saphenous nerve (Sn-SSEPs). Sn-SSEPs are technically challenging to acquire and necessitate advanced troubleshooting skills with a more rigid anesthetic regimen and physiological parameters. Read More

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

AAV2/9-mediated silencing of PMP22 prevents the development of pathological features in a rat model of Charcot-Marie-Tooth disease 1 A.

Nat Commun 2021 04 21;12(1):2356. Epub 2021 Apr 21.

INM, Univ. Montpellier, INSERM, Montpellier, France.

Charcot-Marie-Tooth disease 1 A (CMT1A) results from a duplication of the PMP22 gene in Schwann cells and a deficit of myelination in peripheral nerves. Patients with CMT1A have reduced nerve conduction velocity, muscle wasting, hand and foot deformations and foot drop walking. Here, we evaluate the safety and efficacy of recombinant adeno-associated viral vector serotype 9 (AAV2/9) expressing GFP and shRNAs targeting Pmp22 mRNA in animal models of Charcot-Marie-Tooth disease 1 A.

Diaphragmatic paralysis resulting in respiratory failure as a feature of hepatitis E virus-associated neuralgic amyotrophy.

BMJ Case Rep 2021 Apr 13;14(4). Epub 2021 Apr 13.

Neurology, University Hospitals Plymouth NHS Trust, Plymouth, UK.

Hepatitis E virus (HEV)-associated neuralgic amyotrophy (NA) is often bilateral and severe, involving structures outside the brachial plexus, such as the phrenic nerves or the lumbosacral plexus. We report a case of an HEV-positive man who had presented with brachial neuritis, with significant phrenic nerve involvement, resulting in diaphragmatic paralysis requiring non-invasive ventilation.

Diabetic Neuropathy Project, Tokyo Metropolitan Institute of Medical Science, Tokyo 156-8506, Japan.

Besides its insulinotropic actions on pancreatic β cells, neuroprotective activities of glucagon-like peptide-1 (GLP-1) have attracted attention. The efficacy of a GLP-1 receptor (GLP-1R) agonist exendin-4 (Ex-4) for functional repair after sciatic nerve injury and amelioration of diabetic peripheral neuropathy (DPN) has been reported; however, the underlying mechanisms remain unclear. In this study, the bioactivities of Ex-4 on immortalized adult rat Schwann cells IFRS1 and adult rat dorsal root ganglion (DRG) neuron-IFRS1 co-culture system were investigated. Read More

Hemodynamically unstable pelvic fracture: A damage control surgical algorithm that fits your reality.

Colomb Med (Cali) 2020 Dec 30;51(4):e4214510. Epub 2020 Dec 30.

University of Colorado, Denver Health Medical Center, Department of Surgery, Denver, CO USA.

Pelvic fractures occur in up to 25% of all severely injured trauma patients and its mortality is markedly high despite advances in resuscitation and modernization of surgical techniques due to its inherent blood loss and associated extra-pelvic injuries. Pelvic ring volume increases significantly from fractures and/or ligament disruptions which precludes its inherent ability to self-tamponade resulting in accumulation of hemorrhage in the retroperitoneal space which inevitably leads to hemodynamic instability and the lethal diamond. Pelvic hemorrhage is mainly venous (80%) from the pre-sacral/pre-peritoneal plexus and the remaining 20% is of arterial origin (branches of the internal iliac artery). Read More
