Denial of urinalysis-confirmed opioid use in prescription opioid dependence.
Although research has generally supported the validity of substance use self-reports, some patients deny urine-verified substance use. We examined the prevalence and patterns of denying urinalysis-confirmed opioid use in a sample of prescription opioid dependent patients. We also identified characteristics associated with denial in this population of increasing public health concern. ⋯ Overall, 22.9% of opioid-positive urine tests (149/650) were denied on self-report. Multivariable analysis found that initially using opioids to relieve pain was associated with denying opioid use. These findings support the use of both self-reports and urine testing in treating prescription opioid dependence.

One approach to reduce fatal opioid overdose is by distributing naloxone to law enforcement officers. While several cities have implemented these naloxone programs, little research has investigated officer attitudes about their training. The present research attempts to fill this gap by analyzing survey data from police officers following intranasal naloxone training. ⋯ Distributing naloxone to police officers is likely a trend that will continue so it is important to understand how police officers respond to training to assure that future trainings are as effective as possible. Further research is needed to investigate the impact that these programs have on the community.

Opioids, such as morphine, are the most effective treatment for pain but their efficacy is diminished with the development of tolerance following repeated administration. Recently, we found that morphine activated ERK in opioid-tolerant but not in naïve rats, suggesting that morphine activation of μ-opioid receptors is altered following repeated morphine administration. Here, we have tested the hypothesis that μ-opioid receptor activation of ERK in the ventrolateral periaqueductal gray (vlPAG) is dependent on dynamin, a protein implicated in receptor endocytosis. ⋯ This article is part of a themed section on Opioids: New Pathways to Functional Selectivity.

The use of opioids for both benign and cancer-related chronic pain has increased exponentially over the last few years. For this reason, increasing numbers of such patients are presenting for surgery. ⋯ Patients treated with opioids have special needs in the perioperative setting and it is the anesthesiologist's responsibility to manage these needs optimally. The aim of the present paper is to briefly orient the reader in the management of postoperative pain in patients chronically treated with licit opioids.

Tapentadol prolonged release for patients with multiple myeloma suffering from moderate-to-severe cancer pain due to bone disease.
Myeloma bone disease (MBD) is a devastating complication of multiple myeloma that leads to severe pain. ⋯ Tapentadol PR started in doses of 100 mg/day was effective and well tolerated in opioid-naïve MBD patients with moderate-to-severe pain. Tapentadol PR can be considered a first-choice opioid in cancer patients suffering from mixed pain with a neuropathic component.
