Observational StudyEfficacy and safety profile of prolonged release oxycodone in combination with naloxone (OXN PR) in Parkinson's disease patients with chronic pain.
Pain is a relevant and often underestimated non-motor symptom affecting the quality of life of patients with Parkinson's disease (PD). Although some pain symptoms can be effectively treated by dopaminergic medication, a correct diagnosis of the different types and distribution of pain in PD is challenging, and accordingly, its treatment remains troublesome. We evaluated the efficacy and the safety of a prolonged release oral formulation of oxycodone hydrochloride combined with naloxone hydrochloride dehydrate, in a fixed ratio of 2:1 (OXN PR). ⋯ Low-dose oral OXN PR was efficacious for the management of pain symptoms of patients with PD. More importantly, patients did not experience significant side effects, such as constipation or sedation. Our study provides evidence that opioids can be used to treat pain symptoms in PD patients.

Wounded soldiers often experience substantial pain, which must be addressed before returning to active duty or civilian life. The United States (US) military has instituted several guidelines and initiatives aimed at improving pain management by providing rapid access to medical care, and developing interdisciplinary multimodal pain management strategies based on outcomes observed both in combat and hospital settings. ⋯ The application of US military pain management guidelines has been shown to improve pain monitoring, education and relief. In addition, the US military has instituted the development of programs and guidelines to ensure proper use and discourage aberrant behaviours with regard to opioid use, because opioids are regarded as a critical part of acute and chronic pain management schemes. Inadequate pain management, particularly inadequate chronic pain management, remains a major problem for the general population in the US. Application of military strategies for pain management to the general US population may lead to more effective pain management and improved long-term patient outcomes.

Catheter-tip Granulomas Associated with Intrathecal Drug Delivery - A Two-Center Experience Identifying 13 Cases.
Intrathecal (IT) drug therapy with implanted pumps is an effective treatment modality for chronic pain and/or spasticity, especially after non-invasive treatment has failed. Long-term use of intrathecal opioids may cause formation of inflammatory masses at the tip of intrathecal catheters, possibly leading to neurological deficits and/or catheter revision. ⋯ Our patient cohort with CG differed in some features, of which some like catheter localization, choice, dosage, and the concentration of drugs are potentially modifiable. These results could contribute to the prevention of CG in the future.

Methadone has been a stalwart pharmacologic option for the management of opioid drug dependence for many years. It substitutes for opioid agonists and possesses certain pharmacokinetic properties that confer characteristics preferable to those of other opioids for this application. Methadone is likewise used as an option for the treatment of pain, particularly chronic pain. It has a spectrum of pharmacodynamic activity, including contributions from non-opioid components, that translates to its specific clinical attributes as an analgesic. Unfortunately, basic science studies and accumulated clinical experience with methadone have revealed some undesirable, and even worrisome, features, including issues of safety. The benefit/risk ratio of methadone might be acceptable if there was no better alternative, but neither its pharmacokinetic nor pharmacodynamic properties are unique to methadone. ⋯ Unlike methadone, levorphanol is a more potent NMDA antagonist, possesses a higher affinity for DOR and KOR, has a shorter plasma half-life yet longer duration of action, has no CYP450 interactions or QTc prolongation risk, can be a viable option in the elderly, palliative care, and SCI patients, requires little to no need for co-administration of adjuvant analgesics, and has potentially a lower risk of drug-related Emergency Department visits compared to other opioids.

Associations of borderline personality with pain, problems with medications and suicidality in a community sample of chronic non-cancer pain patients prescribed opioids for pain.
Borderline personality disorder (BPD) is common in patients with chronic non-cancer pain (CNCP). BPD patients often report worse pain and are more likely to abuse opioid medication. Although the prevalence of suicidality is high in both CNCP patients and those with BPD, no studies have examined the interrelationship of BPD, CNCP and suicidality. This article aims to examine the prevalence and associations of BPD in a large community sample of CNCP patients and the association with medication problems and suicidality. ⋯ BPD symptoms were prevalent among people prescribed opioids for CNCP and are associated with a number of adverse consequences. Further, those screening positive were at elevated risk of suicidal behaviors. Careful opioid prescription monitoring and appropriate referrals by clinicians are warranted in BPD with CNCP.
