Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Summary

Early diagnosis and treatment of multiple myeloma (MM) with spinal infiltration, a form of extramedullary plasmacytoma, are crucial. Prompt intervention improves outcomes, while delayed diagnosis leading to paraplegia significantly worsens prognosis.

Area of Science:

  • Hematology
  • Oncology
  • Neurology

Context:

  • Multiple myeloma (MM) can present with extramedullary disease, specifically spinal infiltration, posing diagnostic and therapeutic challenges.
  • Spinal involvement in MM, also known as extramedullary plasmacytoma, requires specific diagnostic and management strategies.
  • Understanding the clinical spectrum of MM with spinal infiltration is essential for timely diagnosis and effective treatment.

Purpose:

  • To investigate the clinical features of multiple myeloma (MM) complicated by spinal infiltration.
  • To improve the understanding and reduce missed diagnoses of MM with extramedullary plasmacytoma affecting the spine.
  • To analyze the efficacy of treatment protocols for MM with spinal infiltration.

Summary:

  • This study analyzed 10 patients with MM complicated by spinal infiltration, examining clinical features, imaging (MRI/CT), and staging (ISS/Duric-Salmon).
  • The most common sites of spinal infiltration were the pectoral cord (7/10), followed by the lumbar (2/10) and sacral cords (1/10).
  • Treatment involving surgery and a protocol including cisplatin, ifosfamide, etoposide, prednisone, and bortezomib achieved an 80% total remission rate with no serious adverse events.

Impact:

  • Early diagnosis and treatment of MM with spinal infiltration are critical for improving patient outcomes.
  • Delayed diagnosis leading to paraplegia significantly diminishes therapeutic efficacy and worsens prognosis.
  • This research highlights the importance of prompt recognition and management of spinal involvement in multiple myeloma.
