AI Article Synopsis
- The brachial and lumbosacral plexuses are essential neural networks that connect the spinal cord to the limbs, involved in sending various types of signals throughout the body.
- Disorders of these plexuses can lead to significant disabilities since they affect multiple nerve fibers from different spinal regions, often requiring tests like electrodiagnostic studies and MRIs to assess the damage.
- Treatment primarily focuses on managing symptoms and rehabilitation, but if a specific cause is identified, surgical interventions like nerve grafts may be considered to restore limb function.
Article Abstract
The brachial and lumbosacral plexuses are complex neural structures that transmit sensory, motor, and autonomic information between the spinal cord and the extremities. Plexus disorders can be particularly disabling because lesions in the plexus usually affect large groups of nerve fibers originating from several spinal levels. Electrodiagnostic studies are often required to confirm a plexus lesion and determine the extent of injury and prognosis. Magnetic resonance is the imaging modality of choice for detecting intrinsic nerve abnormalities; recently, high-resolution ultrasound has emerged as an alternative method for dynamic evaluation and visualization of internal nerve architecture. Once a plexopathy is confirmed, the list of possible etiologies is relatively limited and includes traumatic and nontraumatic causes. Treatment relies on symptom management and physical rehabilitation unless a treatable underlying condition is found. Surgical approaches, including nerve grafts or tendon transfers, may improve limb function when spontaneous recovery is suboptimal.

Article Synopsis
- Autoimmune nodopathy (AN) is a rare disease that can occur alongside membranous nephropathy (MN), and it involves the presence of specific antibodies in the serum.
- A study was done on a 65-year-old male with MN who exhibited symptoms like limb numbness and walking instability, revealing positive anti-CNTN1 antibodies, primarily of the IgG4 subtype, and significant nerve damage.
- The comparison of 35 cases of AN with MN to 51 cases of AN without MN found similar clinical characteristics, suggesting that while AN's symptoms may appear with MN, they do not worsen or improve with the presence of MN.
Phase II Clinical Trial of Second Course of Stereotactic Body Radiotherapy for Spinal Metastases.
Cancers (Basel)
June 2024
Division of Radiation Oncology, Department of Radiology, Tokyo Metropolitan Cancer and Infectious Diseases Center, Komagome Hospital, 3-18-22 Honkomagome, Bunkyo-ku, Tokyo 113-8677, Japan.
Article Synopsis
- A phase II trial was conducted to evaluate the safety and effectiveness of a second course of stereotactic body radiotherapy (SBRT) for patients with spinal metastases who previously received SBRT.
- The trial administered a second SBRT dose of 30 Gy in five fractions, with strict dose constraints to protect the spinal cord and nearby nerves, focusing on the risk of severe radiation-related toxicity.
- Results showed that while there were no cases of radiation myelopathy and good local control was achieved, 25% of patients experienced significant late adverse effects, highlighting a risk of toxicity associated with the treatment.
