ReviewOpioid use and depression in chronic pelvic pain.
Opioid pain medications and antidepressants are commonly prescribed to patients for chronic non-cancer pain. However, little evidence exists for their effectiveness in most pain states, including chronic pelvic pain. ⋯ If patients present for evaluation of disease states such as endometriosis or interstitial cystitis already using regular narcotics, physicians should be aware of ways to mediate misuse and diversion. Women with chronic pain should be screened for depression as well as a history of prior sexual abuse, and treatment or referral initiated when indicated.

Opioids play an important role for the management of acute pain and in palliative care. The role of long-term opioid therapy in chronic non-malignant pain remains unclear and is the focus of much clinical research. ⋯ In this review, we discuss how far human neuroimaging research has come in providing a mechanistic understanding of pain relief provided by opioids, and suggest avenues for further studies that are relevant to the management of chronic pain with opioids. This article is part of the Special Issue Section entitled 'Neuroimaging in Neuropharmacology'.

Contemp Clin Trials · Sep 2014
Randomized Controlled Trial Multicenter Study Comparative StudyDesign considerations for point-of-care clinical trials comparing methadone and buprenorphine treatment for opioid dependence in pregnancy and for neonatal abstinence syndrome.
In recent years, the U.S. has experienced a significant increase in the prevalence of pregnant opioid-dependent women and of neonatal abstinence syndrome (NAS), which is caused by withdrawal from in-utero drug exposure. While methadone-maintenance currently is the standard of care for opioid dependence during pregnancy, research suggests that buprenorphine-maintenance may be associated with shorter infant hospital lengths of stay (LOS) relative to methadone-maintenance. There is no "gold standard" treatment for NAS but there is evidence that buprenorphine, relative to morphine or methadone, treatment may reduce LOS and length of treatment. ⋯ This pair of planned POCCTs would evaluate the comparative effectiveness of treatments for opioid dependence during pregnancy and for NAS. The results could have a significant impact on practice.

ReviewCosts and consequences: a review of discharge opioid prescribing for ongoing management of acute pain.
Over recent years there has been a growing need for patients to be sent home from hospital with prescribed opioids for ongoing management of their acute pain. Increasingly complex surgery is being performed on a day-stay or 23-hour-stay basis and inpatients after major surgery and trauma are now discharged at a much earlier stage than in the past. However, prescription of opioids to be self-administered at home is not without risk. ⋯ Concerns about the potential for harm arising from prescription of opioids for ongoing acute pain management after discharge are relatively recent. However, at a time when serious problems resulting from the non-medical use of opioids have reached epidemic proportions in the community, all doctors must be aware of the potential risks and be able to identify and appropriately manage patients where there might be a risk of prolonged opioid use or misuse. Anaesthetists are ideally placed to exercise stewardship over the use of opioids, so that these drugs can maintain their rightful place in the post-discharge analgesic pharmacopoeia.

Social housing conditions influence morphine dependence and the extinction of morphine place preference in adolescent mice.
Adolescent opioid abuse is on the rise, and current treatments are not effective in reducing rates of relapse. Our previous studies demonstrated that social housing conditions alter the acquisition rate of morphine conditioned place preference (CPP) in adolescent mice. Specifically, the acquisition rate of morphine CPP is slower in morphine-treated animals housed with drug-naïve animals. Thus, here we tested the effect of social housing conditions on the development of morphine dependence and the extinction rate of an acquired morphine CPP. ⋯ Social housing conditions modulate morphine dependence and the extinction rate of morphine CPP. Extinction testing is relevant to human addiction because rehabilitations like extinction therapy may be used to aid human addicts in maintaining abstinence from drug use.
