Efficacy of the anterior ultrasound-guided superior hypogastric plexus neurolysis in pelvic cancer pain in advanced gynecological cancer patients.
Pelvic cancer pain is a chronic pain related to the involvement of viscera, neural, and pelvic muscular. The study was carried out to evaluate the efficacy of anterior ultrasound-guided superior hypogastric plexus neurolysis in pelvic cancer pain in gynecological cancer patients. ⋯ The anterior USG-guided superior hypogastric plexus neurolysis is a useful technique in relieving pelvic pain in gynecological malignancies. However, it requires expertise to perform the block. It also avoids the radiation exposure involved with computed tomography-guided and fluoroscopy-guided superior hypogastric block.

Excessive peptidergic sensory innervation of cutaneous arteriole-venule shunts (AVS) in the palmar glabrous skin of fibromyalgia patients: implications for widespread deep tissue pain and fatigue.
To determine if peripheral neuropathology exists among the innervation of cutaneous arterioles and arteriole-venule shunts (AVS) in fibromyalgia (FM) patients. ⋯ The excessive sensory innervation to the glabrous skin AVS is a likely source of severe pain and tenderness in the hands of FM patients. Importantly, glabrous AVS regulate blood flow to the skin in humans for thermoregulation and to other tissues such as skeletal muscle during periods of increased metabolic demand. Therefore, blood flow dysregulation as a result of excessive innervation to AVS would likely contribute to the widespread deep pain and fatigue of FM. SNRI compounds may provide partial therapeutic benefit by enhancing the impact of sympathetically mediated inhibitory modulation of the excess sensory innervation.

Randomized Controlled Trial
Do cardiorespiratory variables predict the antinociceptive effects of deep and slow breathing?
Deep and slow breathing (DSB) is a central part of behavioral exercises used for acute and chronic pain management. Its mechanisms of action are incompletely understood. ⋯ The present study could not confirm hypotheses that the antinociceptive effects of DSB are related to changes in breathing frequency, heart rate variability, or hypoventilation/hyperventilation when applied as a short-term intervention. It could confirm the notion that increased cardiac parasympathetic activity is associated with reduced pain perception.
