To assess the evidence on the validity of sacral lateral branch blocks and the effectiveness of sacral lateral branch thermal radiofrequency neurotomy in managing sacroiliac complex pain. ⋯ The literature on sacral lateral branch interventions is sparse. One study demonstrates the face validity of multisite, multidepth sacral lateral branch blocks for diagnosis of posterior sacroiliac complex pain. Some evidence of moderate quality exists on therapeutic procedures, but it is insufficient to determine the indications and effectiveness of sacral lateral branch thermal radiofrequency neurotomy, and more research is required.

Review
The state-of-"cultural validity" of self-report pain assessment tools in diverse older adults.
Pain continues to be a significant problem for older adults worldwide and a challenge for health care clinicians and researchers in assuring accurate identification and tailored treatment approaches. Attention has been devoted in recent years to development of pain assessment tools that are reliable and valid for use with older adults, including self-report scales and pain observation tools. ⋯ The multiculturalism of health care and the use of existing pain assessment tools globally require that clinicians and researchers consider tool validity that incorporates the individual's cultural system in order to provide quality pain assessment. This article addresses one aspect of tool development and application across populations, the validation of self-report pain assessment tools for culturally diverse older adults. Recommendations for each the research and clinician are provided to assist in development, translation, and use of various self-report pain assessment tools.

Benzodiazepines (BZDs) are commonly used by chronic pain patients, despite limited evidence of any long-term benefits and concerns regarding adverse events and drug interactions, particularly in older patients. This article aims to: describe patterns of BZDs use; the demographic, physical, and mental health correlates of BZD use; and examine if negative health outcomes are associated with BZD use after controlling for confounders. ⋯ CNCP patients using BZDs daily represent a high-risk group with multiple comorbid mental health conditions and higher rates of emergency health care use. The high prevalence of BZD use is inconsistent with guidelines for the management of CNCP or chronic mental health conditions.

As an analgesic and N-methyl-D-aspartate receptor antagonist, ketamine has been increasingly used as an adjunct in the management of acute perioperative pain. Although several meta-analyses have examined low-dose intravenous (i.v.) ketamine, they do not distinguish between different types of infusions. Additionally, the many clinical trials published on ketamine vary by regimen of administration and surgical site. This review seeks to exclusively examine the evidence supporting the use of low-dose i.v. infusion of ketamine for the management of perioperative pain. ⋯ Thirty-nine clinical trials assessed a continuous infusion or a bolus of low-dose ketamine for postoperative analgesia using reduction of pain scores or reduction of the opioid consumption as the primary endpoint. The mean reduction of opioid consumption when using low-dose i.v. infusion ketamine (infusion rate less than 1.2 mg/kg/h) is 40%. Ketamine also reduces pain scores, but the amplitude of the effect is less clear. No major complications have been reported with low-dose i.v. infusion of ketamine up to 48 hours following surgery.

Observational Study
Use of opioids and other analgesics by older adults in the United States, 1999-2010.
There has been concern over rising use of prescription opioids in young and middle-aged adults. Much less is known about opioid prescribing in older adults, for whom clinical recommendations and the balance of risks and benefits differ from younger adults. We evaluated changes in use of opioids and other analgesics in a national sample of clinic visits made by older adults between 1999 and 2010. ⋯ Opioid use by older adults visiting clinics more than doubled between 1999 and 2010, and occurred across a wide range of patient characteristics and clinic settings.
