Radiation induced Lumbosacral plexophaty (RILP) is a rare but severe complication that has a considerable impact on quality of life. Its occurrence is rare but increasing with improved long-term cancer survival. This entity commonly results in different degrees of sensory and motor deficits. The pathophysiological mechanisms are not yet fully understood. Diagnosis of radiation myelopathy in wom...
The main aim of the present study was to assess the antioxidative effects of human umbilical cord-derived mesenchymal stromal cells (UC-MSCs) in a rat model of radiation myelopathy. UC-MSCs were isolated from Wharton's jelly (WJ) of umbilical cords. An irradiated cervical spinal cord rat model (C2-T2 segment) was generated using a (60)Co irradiator to deliver 30 Gy of radiation. UC-MSCs were in...
Delayed radiation myelopathy (DRM) is a rare disorder that rapidly leads to disabilities, and the median incubation period was reported to be about 2 years (from 6 months to a few years). In this report, we describe a 61-year-old woman who presented with rapid progressive numbness and weakness in both legs 22 months after palliative radiation therapy with 39 Gy in 3 Gy fractions. She was diagno...
Intramedullary spinal cord hemorrhage (hematomyelia) is an uncommon cause of myelopathy and can present in an acute, subacute, stepwise, or chronic fashion. Spinal vascular malformations such as intramedullary cavernomas and intradural arteriovenous malformations are the most common cause of atraumatic intramedullary spinal cord hemorrhage based on the existing literature. Additional considerat...
Introduction: Gait disturbance due to compressive cervical myelopathy has been previously described. However, data on how gait varies with the degree of lower extremity motor impairment are limited. Therefore, we investigated characteristics analysis based severity and determined progresses in myelopathy.
Background: Study of vascular and its secretory profile changes is an important issue in pathogenesis of radiation myelopathy. This paper reports the prostacyclin concentration changes after low-moderate doses of X-irradiation within a short period of time. Materials and Methods: Cervical cords of Wistar rats were irradiated to doses of 0.5, 1, 2, 4 and 6 Gy X-rays. After 24 hours, 2 and 13 ...
