Digital ulcers (DUs) are a severe and frequent clinical feature of patients with systemic sclerosis (SSc). The presence of DUs may cause severe pain and often lead to impairment of patient's functional activities and health-related quality of life. ⋯ These two case reports describe the effectiveness and safety of oxycodone/naloxone in patients with SSc complicated by painful chronic DUs. Such a therapy has provided pain relief and consequently an increased compliance during redressing wounds.

Opioid-Induced Constipation among a Convenience Sample of Patients with Cancer Pain.
Little is known regarding the burden of opioid-induced constipation (OIC) among patients who suffer from cancer-related pain. ⋯ In this primarily UK sample, there appears to be considerable unmet OIC treatment needs among cancer patients.

Clinical trial safety data following chronic administration of extended-release opioids within an older population is limited. Embeda * is an extended-release formulation of morphine sulfate surrounding sequestered naltrexone hydrochloride (MSN) and is designed to deter opioid misuse and abuse. The present analysis compared pooled safety outcomes among patients aged ≥65 years and those aged <65 years from three phase 2/3 studies (ranging from 2 weeks to 12 months) in patients treated with MSN. ⋯ Safety outcomes following daily administration of MSN (2 weeks-12 months) were similar between patients aged ≥65 years and <65 years. Key limitations include the variable study designs and length of treatment (2 weeks-12 months), small sample size, and the inclusion of only those patients who were otherwise in relatively good health with restrictions on concomitant medications.

Opioids are are commonly used for the management of acute and chronic pain. Opioids have different physicochemical and pharmacokinetic characteristics, which explain the profound changes in the clinical effect in several clinical conditions. ⋯ The knowledge of opioid metabolism is essential, particularly for older and complicated patients who receive multiple medications and may have impaired of renal and hepatic function. The recognition of possible metabolic problems and the consideration of adverse drug-drug interactions are fundamental to optimize the use of opioids in clinical practice.

Randomized Controlled Trial Multicenter Study Comparative Study
Continuous wound infiltration or epidural analgesia for pain prevention after hepato-pancreato-biliary surgery within an enhanced recovery program (POP-UP trial): study protocol for a randomized controlled trial.
Postoperative pain prevention is essential for the recovery of surgical patients. Continuous (thoracic) epidural analgesia (CEA) is routinely practiced for major abdominal surgery, but evidence is conflicting on its benefits in this setting. Potential disadvantages of epidural analgesia are a) perioperative hypotension, frequently requiring additional intravenous fluid boluses or prolonged use of vasopressors; b) relatively high failure rates, with periods of inadequate analgesia; and c) the risk of rare but serious, at times persistent, neurologic complications (hematoma and abscess). In recent years, continuous (subfascial) wound infiltration (CWI) plus patient-controlled analgesia (PCA) has been suggested as a safe and reliable alternative, which does not have the previously mentioned disadvantages, but evidence from multicenter trials targeting a specific surgical population is lacking. We hypothesize that CWI+PCA is equally as effective as CEA, without the mentioned disadvantages. ⋯ POP-UP is a pragmatic trial that will provide evidence of whether CWI+PCA is noninferior as compared to (P)CEA after elective hepato-pancreato-biliary surgery via laparotomy in an enhanced recovery setting. If this hypothesis is confirmed, this finding could contribute to more widespread implementation of this technique, especially when the described disadvantages of epidural analgesia are less often observed with CWI+PCA.
