Intrathecal drug delivery is an effective and safe option for the treatment of chronic pathology refractory to conventional pain therapies. Typical intrathecal administered drugs are opioids, baclofen, local anesthetics and adjuvant medications. Although knowledge about mechanisms of action of intrathecal drugs are every day more clear many doubt remain respect the correct location of intrathecal catheter in order to achieve the best therapeutic result. ⋯ In the second category, the variables in CSF flow, are considered that can modify the drug distribution within the CSF with special attention to the new theories of liquoral circulation. Last category try to explain inter-individual difference in baclofen response with difference that are specific for each patients such as the anatomical area to treat, patient posture or reaction to inflammatory stimulus. We conclude that a comprehensive evaluation of the patients, including imaging techniques to study the anatomy and physiology of intrathecal environment and CSF dynamics, could become essential in the future to the purpose of optimize the clinical outcome of intrathecal therapy.

Does preoperative risk for delirium moderate the effects of postoperative pain and opiate use on postoperative delirium?
To investigate whether preoperative risk for delirium moderates the effect of postoperative pain and opioids on the development of postoperative delirium. ⋯ High levels of postoperative pain and using high opioid doses increased risk for postoperative delirium for all patients. The highest incidence of delirium was among patients who had high preoperative risk for delirium and also had high postoperative pain and used high opioid doses.

One of the barriers to cancer pain control and palliative care (PC) development is the misconception that the use of opioids may hasten death. This concern is exaggerated when higher doses of opioids are used at the end-of-life. The aim of this study was to investigate the relationship between survival and the dose of opioids used at the end-of-life of patients with advanced cancer in an Egyptian PC setting. ⋯ The results suggest that the dose of opioids has no detrimental impact on the survival of patients with advanced cancer in an Egyptian PC setting. Further research is needed to overcome barriers to cancer pain control especially in settings with inadequate cancer pain control.

This study examined the motives for medical misuse of prescription opioids among adolescents and assessed differences in motives by demographic characteristics, substance abuse, and diversion behaviors. A survey was conducted in 2011 to 2012 and the sample consisted of 2,964 adolescents (51% female). Thirteen percent reported past-year medical use of prescription opioids. Among those prescribed opioids in the past year (n = 393), 17.9% reported medical misuse (eg, using too much, using to get high, or using to increase alcohol or other drug effects). The most prevalent motives for medical misuse were "to relieve pain" (84.2%) and "to get high" (35.1%). Multivariate analyses indicated that the motives differed by race, and that different motives were associated with different substance abuse and diversion behaviors. The odds of past-year substance abuse among medical misusers motivated by non-pain relief were more than 15 times greater than for nonusers (adjusted odds ratio = 15.2, 95% CI = 6.4-36.2, P < .001). No such differences existed between nonusers and appropriate medical users, or between nonusers and medical misusers motivated by pain relief only. These findings improve our understanding of opioid medication misuse among adolescents and indicate the need for enhanced education about appropriate medical use, pain management, and patient communication with prescribers. ⋯ This article represents the first investigation to examine the motives associated with medical misuse of prescription opioids among adolescents. The results indicate that the majority of medical misuse is associated with pain relief. This information could be used to develop strategies to reduce opioid medication misuse among adolescents.

The primary objective of this study was to measure prescribing compliance with the Veterans Affairs/Department of Defense treatment guidelines for chronic non-cancer pain (CNCP) in the primary care setting. We also determined the proportion of subjects who demonstrated aberrant drug-related behaviors (ADRBs) and the patient characteristics associated with them. ⋯ This article studied the prescribing practices of opioids in a primary care setting and can be used to enhance provider education regarding chronic pain guidelines.
