ReviewOpioid use and the risk of respiratory depression and death in the pediatric population.
Pediatric patients may be at an increased risk of adverse effects from various medications. Recently, there have been a number of serious adverse events, including several pediatric patients experiencing severe respiratory depression and death as a result of the use of codeine for pain control following tonsillectomy and adenoidectomy. ⋯ Opioid-associated respiratory depression was very rare and no deaths were reported in the reviewed studies. These findings under the well-defined conditions of controlled studies may not be the best means of determining overall opioid-associated side effects in pediatric patients.

Little is known about how far opioid shoppers travel or how often they cross state lines to fill their opioid prescriptions. This retrospective cohort study evaluated these measures for opioid shoppers and nonshoppers using a large U.S. prescription database. Patients with ≥3 opioid dispensings were followed for 18 months. A subject was considered a shopper when he or she filled overlapping opioid prescriptions written by >1 prescriber at ≥3 pharmacies. A heavy shopper had ≥5 shopping episodes. Outcomes assessed were distance traveled among pharmacies and number of states visited to fill opioid prescriptions. A total of 10,910,451 subjects were included; .7% developed any shopping behavior and their prescriptions accounted for 8.6% of all opioid dispensings. Shoppers and heavy shoppers were younger than the nonshoppers. Shoppers traveled a median of 83.8 miles, heavy shoppers 199.5 miles, and nonshoppers 0 miles. Almost 20% of shoppers or heavy shoppers, but only 4% of nonshoppers, visited >1 state. Shoppers traveled greater distances and more often crossed state borders to fill opioid prescriptions than nonshoppers, and their dispensings accounted for a disproportionate number of opioid dispensings. Sharing of data among prescription-monitoring programs will likely strengthen those programs and may decrease shopping behavior. ⋯ This study shows that opioid shoppers travel greater distances and more often cross state borders to fill opioid prescriptions than nonshoppers, and their dispensings accounted for a disproportionate number of opioid dispensings. The findings support the need for data sharing among prescription-monitoring programs to deter opioid shopping behavior.

To estimate the yearly economic burden of opioid-related poisoning in the United States. ⋯ Opioid-related poisoning causes a substantial burden to the United States each year. Costs related to mortality account for the majority of costs. Interventions designed to prevent or reverse opioid-related poisoning can have significant impacts on cost, especially where death is prevented.

Glia plays a crucial role in the maintenance of neuronal homeostasis in the central nervous system. The microglial production of immune factors is believed to play an important role in nociceptive transmission. Pain may now be considered a neuro-immune disorder, since it is known that the activation of immune and immune-like glial cells in the dorsal root ganglia and spinal cord results in the release of both pro- and anti-inflammatory cytokines, as well as algesic and analgesic mediators. ⋯ The other way of pain control can be the decrease of pro-nociceptive agents like transcription factor synthesis (NF-kappaB, AP-1); kinase synthesis (MEK, p38MAPK, JNK) and protease activation (cathepsin S, MMP9, MMP2). Additionally, since it is known that the opioid-induced glial activation opposes opioid analgesia, some glial inhibitors, which are safe and clinically well tolerated, are proposed as potential useful ko-analgesic agents for opioid treatment of neuropathic pain. This review pointed to some important mechanisms underlying the development of neuropathic pain, which led to identify some possible new approaches to the treatment of neuropathic pain, based on the more comprehensive knowledge of the interaction between the nervous system and glial and immune cells.

Development of Opioid Overdose Knowledge (OOKS) and Attitudes (OOAS) Scales for take-home naloxone training evaluation.
To develop an Opioid Overdose Knowledge Scale (OOKS) and an Opioid Overdose Attitudes Scale (OOAS) to evaluate take-home naloxone training. ⋯ The 45-item OOKS and 28-item OOAS are suitable as outcome measures of take-home naloxone training for friends and family members of opioid users.
