Resiniferatoxin (RTX) is a potent synthetic agonist for transient receptor potential vanilloid subtype 1 (TRPV1), which has a selectivity for antinociception. The analgesic effect of epidural RTX in a rat model of neuropathic pain has not yet been studied. ⋯ RTX has potential to be used in an epidural route for neuropathic pain in a rat model with a relatively small amount, which produces transitory improvement of mechanical hypersensitivity and prolonged thermal analgesic response.

Acrolein signaling is important during spinal cord injury; whether it is involved in somatic and emotional pain is not clear. Hydralazine is a potent antihypertensive drug and can scavenge acrolein efficiently. ⋯ Based on the above findings, hydralazine may find its new application of analgesia within a safe dose window (around one mg/kg of body weight) without causing severe side effects.

Review Meta Analysis
The long-term incidence of subsequent vertebral body fracture after vertebral augmentation therapy: a systemic review and meta-analysis.
Vertebroplasty and kyphoplasty have recently been used to treat painful osteoporotic compression fractures. Early clinical results have been encouraging, but very little is known about the consequences of augmentation with cement for adjacent, unaugmented levels. ⋯ Although vertebral augmentation therapies, such as vertebroplasty and kyphoplasty, have been widely used in clinics to treat patients' back pain caused by vertebral compression fractures due to osteoporosis, no evidence shows that they can increase the fracture of adjacent vertebral bodies.
