This review will provide an overview of pharmacokinetics and clinical practice considerations of the novel formulations of fentanyl for the treatment of breakthrough cancer pain. First, we provide a brief description of the physicochemical properties of fentanyl. ⋯ Advancements in the formulations and delivery of fentanyl have provided a safer and more effective treatment for breakthrough cancer pain. These dosage forms offer overlapping yet distinct pharmacokinetic advantages to allow more choices for physicians and patients in the management of breakthrough cancer pain.

To evaluate factors and methods associated with self-management of pain among people who inject drugs (IDUs) in Vancouver (Canada). ⋯ Self-management of pain was common among IDUs who reported moderate-to-extreme pain in this setting, particularly among those who had been refused a prescription for pain medication and those who had ever been homeless. These data highlight the challenges of adequate pain management among IDUs.

Suffering chronic pain is a global epidemic that requires a closer look on how we are educating trainees to become more effective in pain management. The vast majority of medical professionals will encounter treatment of pain throughout their career. ⋯ Reviews have demonstrated dissatisfaction among practitioners throughout the world on how pain education is currently conducted. Changing the educational process will require support from several areas: medical educators, clinicians, policymakers, administrators and several other organizations.

Substantial evidence reveals that the fear of pain and pain anxiety play a significant role in the development of chronic pain and disability, although underlying mechanisms remain widely unknown. Recent studies indicate that endurance pain responses are important besides avoidance. The purpose of this brief narrative review is to provide an overview of research that argues for the integration of the mechanisms of associative learning, motivation and emotion regulation in order to understand the questions of how and why individuals respond with pain responses, which lead to long-term suffering. By using the avoidance-endurance model of pain, we provide a concept that elucidates a range of responses to pain, fear and anxiety that mediate the transition from acute to chronic pain.

Persistent pain after breast cancer surgery (PPBCS) is increasingly recognized as a potential problem facing a sizeable subset of the millions of women who undergo surgery as part of their treatment of breast cancer. Importantly, an increasing number of studies suggest that individual variation in psychosocial factors such as catastrophizing, anxiety, depression, somatization and sleep quality play an important role in shaping an individual's risk of developing PPBCS. This review presents evidence for the importance of these factors and puts them within the context of other surgical, medical, psychophysical and demographic factors, which may also influence PPBCS risk, as well as discusses potential perioperative therapies to prevent PPBCS.
