Randomized Controlled Trial
Thoracic paravertebral block for nephrectomy: a randomized, controlled, observer-blinded study.
This study evaluated whether adding a preoperative single thoracic paravertebral block (TPVB) to intravenous patient-controlled analgesia (IV PCA) would improve postoperative analgesia compared with using IV PCA alone in patients undergoing nephrectomy. ⋯ A preoperative single TPVB improved postoperative analgesia by reducing the postoperative pain score and fentanyl consumption in patients undergoing nephrectomy.

Randomized Controlled Trial
Immediate analgesic effect of 8% lidocaine applied to the oral mucosa in patients with trigeminal neuralgia.
Trigeminal nerve block is widely used for trigeminal neuralgia (TN), though with much painful procedure and potential serious complications. The pain of TN occurs most frequently in the second and the third divisions of the trigeminal nerve, which are distributed in intraoral mucous membrane as well as face skin. Here, we examined the response to intraoral application of 8% lidocaine (LDC) in patients with oral TN pain in a double-blind, placebo (PBO)-controlled crossover study. ⋯ Intraoral application of 8% LDC produced prompt analgesia without serious side effects in patients with TN who presented with severe intraoral pain.

Editorial Comment
Preventing pain requires translating biology into social change.

Chronic pain is a significant concern for the Veterans Health Administration (VHA), with chronic pain conditions among those most frequently reported by Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF)/Operation New Dawn (OND) veterans. The current study examined VHA electronic medical record data to examine variation in demographics and high prevalence and high impact medical and mental health conditions in order to characterize the differences between patients with persistent pain and no pain. ⋯ The operational definition of chronic pain used in this study may have research implications for examining predictors of incident and chronic pain. These data have important clinical implications in that addressing comorbid conditions of persistent pain may improve adaptive coping and functioning in these patients.

The field of pain-related research has gained more attention as the prevalence of chronic pain increased over the years. The objective of this research was to identify highly cited papers, as well as contributors, to pain-related research. ⋯ An indicator like the MCI can provide a proxy for the contributions made by an individual or institution. It reflects the independent research ability and leadership. In future evaluations of institution or individual performances, the MCI should be included, together with the number of total papers, to provide a better profile of research performance.
