Multicenter Study
Long-term usage of narcotic analgesics by chronic intractable noncancer pain patients in Taiwan from 2003 to 2012.
Chronic pain is a common and important medical problem worldwide. Patients with chronic intractable noncancer pain (CINCP) are treated primarily with narcotics. We analyzed the characteristics of patients with CINCP and the pain prescriptions of Taiwan's physicians. ⋯ To decrease malaise and addiction in patients with CINCP, Taiwan's physicians need more education on narcotic analgesics, and greater professional cooperation to develop therapeutic guidelines that will improve pain care for patients with CINCP.

Genetic variation and cognitive dysfunction in opioid-treated patients with cancer.
The effects of single-nucleotide polymorphisms (SNPs) on the cognitive function of opioid-treated patients with cancer until now have not been explored, but they could potentially be related to poor functioning. This study aimed at identifying associations between SNPs of candidate genes, high opioid dose, and cognitive dysfunction. ⋯ The findings did not support influence of those SNPs analyzed to explain cognitive dysfunction in opioid-treated patients with cancer.

Multicenter StudyLong-term safety of fentanyl sublingual spray in opioid-tolerant patients with breakthrough cancer pain.
The current study assessed the long-term safety of fentanyl sublingual spray for managing breakthrough cancer pain (BTCP). ⋯ This long-term maintenance study demonstrated that fentanyl sublingual spray was generally safe and well tolerated for managing BTCP over a 90-day period.

Multicenter StudyTrends in analgesic exposures reported to Texas Poison Centers following increased regulation of hydrocodone.
In October 2014, the Drug Enforcement Administration reclassified hydrocodone to schedule II, increasing regulations on use. The impact of rescheduling hydrocodone on opioid exposures is unclear, especially in states with special restrictions required for prescribing schedule II agents. ⋯ The increased regulation was temporally associated with decreased hydrocodone exposures reported to Texas Poison Centers.

Multicenter Study Observational Study
Remifentanil and worse patient-reported outcomes regarding postoperative pain management after thyroidectomy.
Intraoperative remifentanil has been associated with postoperative hyperalgesia, higher visual analogic pain scores, and increased postoperative morphine consumption. However, this has not been investigated from patient's perspective by using a patient-reported outcomes (PROs) approach with a validated questionnaire. ⋯ Our study suggests that remifentanil-based anesthesia is associated with worse pain-related PROs in patients undergoing thyroidectomy despite more frequent intraoperative analgesic administration. This study adds further evidence to the growing literature about opioid- and remifentanil-induced hyperalgesia.
