To assess the transcultural equivalency of the Spanish version of the Fibromyalgia Rapid Screening Tool (FiRST) and its discriminatory ability in different Latin American samples. ⋯ The Spanish version of the FiRST may be used as a screening tool for fibromyalgia in several Latin American subsamples, even in those patients with high scores on potential confounders. In Spain and Mexico, the low specificity of the FiRST suggests, however, that it would be best used to support a suspected diagnosis of fibromyalgia, rather than to exclude the diagnosis.

Randomized Controlled Trial
Buprenorphine, Clonidine, Dexamethasone, and Ropivacaine for Interscalene Nerve Blockade: A Prospective, Randomized, Blinded, Ropivacaine Dose-Response Study.
This study investigated interscalene block for shoulder arthroplasty with various ropivacaine concentrations in the presence of clonidine, dexamethasone, and buprenorphine. The goal was prolonged analgesia with minimal motor blockade. ⋯ For maximum pain reduction, combining perineural additives with ropivacaine 0.375% or 0.2% is suggested. To minimize motor blockade, perineural additives can be combined with ropivacaine, 0.1%.

Patellofemoral pain (PFP) is common among young individuals. Female adolescents with PFP present typically with localized mechanical hyperalgesia around the knee, but the effect of central pain mechanisms are unknown. This study aimed to compare temporal summation of pain, conditioned pain modulation (CPM), and widespread hyperalgesia in young female adults with PFP and age-matched pain-free controls. ⋯ Young female adults with long-standing PFP demonstrated impaired CPM. This is important because PFP, a peripheral pathology, might have important central components that need to be studied in order to understand its extent and therapeutic implications.

Review Case Reports
Deconstructing Chronic Low Back Pain in the Older Adult-Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part VII: Insomnia.
OBJECTIVE : To present the seventh in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. This article focuses on insomnia and presents a treatment algorithm for managing insomnia in older adults, along with a representative clinical case. METHODS : A modified Delphi process was used to develop the algorithm and supportive materials. ⋯ Medications should be considered only if BBTI/CBTI is suboptimal or not effective and should be prescribed at the lowest effective dose for short periods of time (< 90 days). CONCLUSIONS : Insomnia is commonly comorbid with CLBP in older adults and should be routinely evaluated and treated because it is an important contributor to pain and disability. The algorithm presented was structured to assist primary care providers in planning treatment for older adults with CLBP and insomnia.
