Randomized Controlled Trial
Influence of morphine and naloxone on pain modulation in Rheumatoid Arthritis, Chronic Fatigue Syndrome/Fibromyalgia and controls: a double blind randomized placebo-controlled cross-over study.
Impaired pain inhibitory and enhanced pain facilitatory mechanisms are repeatedly reported in patients with central sensitization pain. However, the exact effects of frequently prescribed opioids on central pain modulation are still unknown. ⋯ This study revealed anti-hyperalgesia effects of morphine in CFS/FM and RA patients. Nevertheless, these effects were comparable to placebo. Besides, neither morphine nor naloxone influenced deep tissue pain, temporal summation or CPM. Therefore, these results suggest that the opioid system is not dominant in (enhanced) bottom-up sensitization (temporal summation) or (impaired) endogenous pain inhibition (CPM) in patients with CFS/FM or RA.

Pain control after open abdominal surgery often includes multimodal analgesia with thoracic epidural or transversus abdominis plane (TAP) block. After liposomal bupivacaine was approved for TAP blocks in 2015, it became an alternative to indwelling catheters. However, the pharmacokinetics and safety of its use during the perioperative period have not been thoroughly investigated, especially in conjunction with parenteral opioids. We present a case report of an elderly patient having urgent laparoscopic converted to open abdominal surgery, who experienced postoperative respiratory depression in the recovery room after multimodal therapy with liposomal bupivacaine TAP blocks, intravenous (IV) opioids, and ketorolac.

Opioids are frequently used for the treatment of chronic pain, and patients taking high doses are at increased risk of complications and adverse opioid-related events. Ketamine is appealing as an opioid adjunct because of its lack of respiratory depression and potential prevention of hyperalgesia and central sensitization. We present a case in which a ketamine infusion was utilized over a 7-day period to provide rapid taper of a daily dose of 400 mg of morphine equivalents to less than one-third of that dose on discharge with unchanged pain levels and no symptoms of opioid withdrawal.

Renal colic is a common, acute presentation of urolithiasis that requires immediate pain relief. European Association of Urology guidelines recommend nonsteroidal anti-inflammatory drugs (NSAIDs) as the preferred analgesia. However, the fear of NSAID adverse effects and the uncertainty about superior analgesic effect have maintained the practice of advocating intravenous opioids as the initial analgesia. ⋯ In kidney stone-related acute pain episodes in patients with adequate renal function, treatment with nonsteroidal anti-inflammatory drugs offers effective and most sustained pain relief, with fewer side effects, when compared with opioids or paracetamol.

Opioid use and stigma: The role of gender, language and precipitating events.
The stigma of drug addiction is associated with negative perceptions and can be a barrier to treatment. With the rise in opioid overdose deaths, understanding stigmatizing attitudes towards individuals who use opioids is a crucial matter. There is a lack of opioid use research on stigma and, therefore, we aimed to discern stigmatizing attitudes towards people with opioid addiction. ⋯ Our results indicated that there were higher stigmatizing attitudes overall towards a male, an individual labeled as a "drug addict" and an individual who took prescription opioids from a friend. Interaction effects also showed that a female labeled with an "opioid use disorder" and male labeled as a "drug addict" were rated with higher stigma. The findings from our study are the first to show that information about gender, precipitating events and language matter when assessing stigma and opioid use and may affect the delivery of patient care.
