Treatment of back pain due to facet joint syndrome has been a challenge for physicians since its recognition ∼80 years ago. Intra-articular injections of steroids, local anesthetics, and phenol have been widely adopted despite their known shortcomings. Recently, intra-articular injection of amniotic membrane-umbilical cord (AMUC) has been utilized in various orthopedic indications, including those involving synovial joints, due to its reported anti-inflammatory properties. ⋯ No adverse events, repeat procedures, or complications were reported. Intra-articular injection of AMUC appears to be promising for managing facet pain and mitigating opioid use. Further investigation with larger sample size is warranted.

Bacterial meningitis and cauda equina syndrome after trans-sacral epiduroscopic laser decompression: A case report.
Trans-sacral epiduroscopic laser decompression (SELD) is a noninvasive pain-relieving procedure for treatment of herniated lumbar disc (HLD), and is known to have positive effects in alleviating lower back pain or radicular leg pain after HLD. However, little is known about the possible complications of SELD. ⋯ In this study, we described a patient who had bacterial meningitis after SELD. During SELD, clinicians should keep in mind the possibility of infection.

Patients with ulcerative colitis (UC) are at increased risk of developing colitis-associated colon cancer. Accumulating evidence suggests that follicular T helper (TFH) cells play a crucial role in the pathogenic process of autoimmune diseases. However, little is known about the role of TFH cells in the development of UC. ⋯ Moreover, aberrant frequencies of different subsets of B cells were observed in UC patients, and a positive correlation was found between CD38CD19 B cells and TFH cells and between CD86CD19 B cells and TFH cells. A high number of TFH cells were positively associated with Mayo score, serum C-reaction protein (CRP) and serum IgG in UC patients. Our data indicate that TFH cells and IL-21 are involved in the pathogenesis of UC.
