ReviewExperimental and procedural pain responses in primary dysmenorrhea: a systematic review.
Primary dysmenorrhea (PD) has been the focus of a number of experimental pain studies. Although a number of reviews exist, few have critically evaluated the existing body of research on PD and experimental and procedural pain. ⋯ However, there is an abundance of conflicting findings, which may be due to significant methodological issues such as inconsistent definitions of PD, wide variation in experimental pain methodologies, and inaccurate assessment of the menstrual cycle. Future research should focus on identifying specific symptoms (i.e., pain threshold ratings) to more clearly define what constitutes PD, establish reliable and valid laboratory testing protocols, and assess the menstrual cycle with greater precision.

Cognitive effects of electro-acupuncture and pregabalin in a trigeminal neuralgia rat model induced by cobra venom.
The objective of this study was to investigate the effects of electro-acupuncture (EA) and pregabalin on cognition impairment induced by chronic trigeminal neuralgia (TN) in rats. ⋯ EA and pregabalin could alleviate TN induced by cobra venom. EA could also inhibit the cognition deficit induced by TN, while pregabalin could not.

Long-term safety and analgesic efficacy of buprenorphine buccal film in patients with moderate-to-severe chronic pain requiring around-the-clock opioids.
This open-label, single-arm study was conducted to evaluate the long-term safety and efficacy of a novel buprenorphine formulation, buprenorphine buccal film, in the treatment of moderate-to-severe chronic pain requiring around-the-clock opioids. ⋯ In appropriate patients, buprenorphine buccal film demonstrated tolerability and efficacy in the long-term management of chronic pain.

Analysis of perioperative pain management in vascular surgery indicates that practice does not adhere with guidelines: a retrospective cross-sectional study.
Inadequate treatment of pain related to surgery may be associated with complications and prolonged recovery time and increased morbidity and mortality rates. We investigated perioperative pain management in vascular surgery and compared it with the relevant guidelines for the treatment of perioperative pain. ⋯ The study indicates that management of surgery-related pain in complex vascular procedures at this hospital did not follow guidelines for the management of acute perioperative pain. Our finding that most patients did not receive appropriate analgesia after vascular surgery leads to the conclusion that the institution would benefit from developing guidelines for the management of acute perioperative pain, which should be applied in all cases.

Health care resource use and cost differences by opioid therapy type among chronic noncancer pain patients.
The study assessed 12-month chronic pain (CP)-related health care utilization and costs among chronic noncancer pain (CNCP) patients who initiated various long-term opioid treatments. Treatments included monotherapy with long-acting opioids (mono-LAOs), mono-therapy with short-acting opioids (mono-SAOs), both LAOs and SAOs (combination), and opioid therapy initiated with SAO or LAO and switched to the other class (switch). Using MarketScan® claims databases (2006-2012), we identified CNCP patients with ≥90 days opioid supply after pain diagnosis and continuous enrollment 12 months before pain diagnosis (baseline period) and 12 months after opioid start (post-index period). ⋯ Use of pain-related medications and other treatment modalities was also significantly lower in the mono-LAO cohort relative to the other cohorts. CNCP patients using long-term monotherapy with LAOs had the lowest CP-related total health care costs in the 12 months after opioid initiation compared with mono-SAO, switch, or combination patients despite higher opioid daily doses and higher prescription costs. Future research accounting for severity and duration of pain would aid in determining the optimal long-term opioid regimen for CNCP patients.
