Back pain is a common clinical symptom. Degeneration of intervertebral discs is one of the most important factors leading to back pain, namely, discogenic back pain. However, at present, the understanding of lumbar intervertebral discs causing back pain is confined to biomechanical and histological studies. ⋯ Therefore, study of neural mechanisms that are involved in progression of discogenic back pain will provide additional assistance for treatment of its symptoms. We review the anatomical structure of intervertebral discs and the related neural mechanisms involved in discogenic back pain. We also discuss the current view of neural mechanisms underlying discogenic back pain.

Previous studies comparing surgical pleth index (SPI)-guided and conventional analgesia have shown differing results. Therefore, we compared the intraoperative opioid requirement, extubation time, postoperative pain scores, and perioperative adverse events between these two modalities. ⋯ Compared with conventional analgesia, SPI-guided analgesia can reduce intraoperative opioid consumption and facilitate extubation. Moreover, no intergroup difference was observed in the degree of postoperative pain or incidence of perioperative adverse events.

The study aim was to examine the hand function (hand strength and dexterity) and intervention effects of training in adults with Prader-Willi syndrome (PWS). ⋯ All subjects showed lower hand strength and poorer manual/finger dexterity compared with healthy adults; this should be considered during physical training programs. Owing to limitations in the intervention intensity and possible subject behavioral deficits, further research is needed to clarify the effects of this intervention on hand function in PWS patients.
