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.

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.

Postbariatric surgery neuropathic pain (PBSNP): case report, literature review, and treatment options.
This study is aimed at facilitating clinician understanding of factors associated with postbariatric surgery neuropathic pain (PBSNP) and discussing the evidence base for management options. ⋯ A better understanding of the peripheral and central mechanisms resulting in PBSNP is likely to promote the development of targeted and effective treatments.
