Controlled Clinical Trial
Evaluation of the Effectiveness of Autologous Bone Marrow Mesenchymal Stem Cells in the Treatment of Chronic Low Back Pain Due to Severe Lumbar Spinal Degeneration: A 12-Month, Open-Label, Prospective Controlled Trial.
Regenerative medicine interventions are applied to assist in the repair, and to potentially replace or restore damaged tissue through the use of autologous/allogenic biologics and it continues to expand. The anti-inflammatory, immunomodulatory, and regenerative properties of bone marrow mesenchymal stem cells (BM-MSCs), and investigation into their therapeutic efficacy and safety in patients with severe chronic low back pain, have not been demonstrated in controlled studies. Multiple pain generators have been hypothesized to be responsible in severe spinal degeneration and it is difficult to identify a single pain generator; consequently, resulting in inadequate therapeutic results. ⋯ The first available controlled study utilizing BM-MSCs in severe degenerative spinal disease with interventions into multiple structures simultaneously, including disc, facet joints, nerve roots, and sacroiliac joint based on symptomatology, showed promising results.

Randomized Controlled Trial
Comparison of Increase in the Optic Nerve Sheath Diameter between Epidural Saline and Contrast Medium Injections.
Normal saline or contrast medium is one of the widely used injection materials during fluoroscopic guided injections. Optic nerve sheath diameter (ONSD) measurement is a reliable and noninvasive method for intracranial pressure evaluation. ⋯ Thoracic epidural injection of 5 mL normal saline or contrast medium resulted in a significant increase of ONSD compared to baseline; however, the degree of ONSD increase was more attenuated in the contrast group than the saline group.
