Discrepancies in prevalence estimates in two national surveys for nonmedical use of a specific opioid product versus any prescription pain reliever.
There is a growing need to understand trends in nonmedical use of prescription pain relievers as a class, as well as specific opioid products. Surveys such as monitoring the future (MTF) and the National Survey on Drug Use and Health (NSDUH) are important tools for understanding trends in abuse of prescription and illegal drugs. This report compares discrepancies in prevalence between these surveys for a specific opioid product (oxycodone) relative to other drugs. ⋯ The discrepancy between surveys in prevalence estimates for nonmedical use of oxycodone exceed those for other drugs, pointing to the importance of visual aids and items used to measure the nonmedical use of specific products.

Voices that may not otherwise be heard: a qualitative exploration into the perspectives of primary care patients living with chronic pain.
Although psychometrically sound pain assessment tools are available, there is a paucity of research that comprehensively defines chronic pain from the perspective of patients. The purpose of this study was to examine the utility of a combination of qualitative methods (Photovoice, one-on-one interviews, and focus groups) in examining the daily experiences of primary care patients living with chronic pain. ⋯ The qualitative methods employed in this study provide deep insight into perceptions and experiences of patients living with chronic pain that is vital for informing future clinical interventions.

Scientometric assessment of drugs for chronic pain, 1979-2013: rapid growth of publications, paucity of successful drugs.
The aim of this study was to find signs of progress in the pharmacotherapy of chronic pain over the past 35 years using scientometric analysis. The following scientometric indices were used: 1) popularity index, representing the share of articles on a specific drug(s) relative to all articles in the field of chronic pain; 2) index of change, representing the degree of growth in publications on a topic from one period to the next; 3) index of expectations, representing the ratio of the number of articles on a topic in the top 20 journals relative to the number of articles in all (>5,000) biomedical journals covered by PubMed; and 4) index of ultimate success, representing a publication outcome when a new drug takes the place of a common drug previously used for the same purpose. Publications on 55 drugs used in the treatment of chronic pain were assessed during seven 5-year periods, from 1979 to 2013. ⋯ None of the drugs had a high index of expectations in 2009-2013. The index of ultimate success was positive only with triptans in the relatively limited area of acute treatment of migraine. As a result, despite rapid growth in the number of publications, our scientometric analysis did not reveal signs of substantial progress in the field of pharmacotherapy for chronic pain.

Utility of opium seed extract tests in preventing hypersensitivity reactions during surgery.
Anaphylaxis during anaesthesia is fatal in 3-9% of patients and analgesics, including opioids, and is the second most common medicament-related cause, although the prevalence is underestimated. We recently found that patients may generate IgE antibodies to opium seeds. ⋯ Sensitivity to opioids and intraoperative anaphylaxis can be diagnosed by routine tests. IgE and skin tests for the oil body fraction of P. somniferum had the highest sensitivity for sensitisation to opioids.

Two different patterns of breathlessness have been identified: chronic or continuous breathlessness and breathlessness crisis (acute, incident, episodic, breakthrough breathlessness). Meta-analysis and systematic reviews prove that opioids are beneficial in either opioid-naïve or -tolerant patients. However, data from two recent randomised controlled trials were not able to show the effectiveness of fentanyl for the relief of exertion-induced dyspnoea.
