Review Meta Analysis
Perineural dexamethasone added to local anesthesia for brachial plexus block improves pain but delays block onset and motor blockade recovery.
Multiple studies have shown that perineural dexamethasone improves postoperative analgesia. However, some studies have shown minimal benefit, and have raised concerns regarding adverse physio-chemical effects of perineural dexamethasone. Furthermore, there is a paucity of studies wherein control (IV) dexamethasone was considered. ⋯ Perineural dexamethasone addition to local anesthetic solutions significantly improved postoperative pain in brachial plexus block without increasing complications. However, perineural adjuvant dexamethasone delayed the onset of sensory and motor block, and prolonged the duration of motor block. Smaller doses of dexamethasone (4 - 5 mg) were as effective as higher doses (8 - 10 mg).

Randomized Controlled Trial Comparative Study
Comparison of the effects of adding dexmedetomidine versus midazolam to intrathecal bupivacaine on postoperative analgesia.
Dexmedetomidine and midazolam both modulate spinal analgesia by different mechanisms, and yet, no human studies are available to compare them for postoperative analgesia after neuraxial administration. ⋯ The addition of dexmedetomidine (5 mcg) to 3 mL of intrathecal hyperbaric bupivacaine (0.5%) significantly prolongs the duration of effective analgesia in comparison to 1 mg midazolam or placebo (0.9% normal saline) with a comparable incidences of side effects.

Scientific peer review is pivotal in health care research in that it facilitates the evaluation of findings for competence, significance, and originality by qualified experts. While the origins of peer review can be traced to the societies of the eighteenth century, it became an institutionalized part of the scholarly process in the latter half of the twentieth century. This was a response to the growth of research and greater subject specialization. ⋯ Various types of peer review bias include content-based bias, confirmation bias, bias due to conservatism, bias against interdisciplinary research, publication bias, and the bias of conflicts of interest. Consequently, peer review would benefit from various changes and improvements with appropriate training of reviewers to provide quality reviews to maintain the quality and integrity of research without bias. Thus, an appropriate, transparent peer review is not only ideal, but necessary for the future to facilitate scientific progress.

The high prevalence of chronic persistent neck pain not only leads to disability but also has a significant economic, societal, and health impact. Among multiple modalities of treatments prescribed in the management of neck and upper extremity pain, surgical, interventional and conservative modalities have been described. Cervical epidural injections are also common modalities of treatments provided in managing neck and upper extremity pain. They are administered by either an interlaminar approach or transforaminal approach. ⋯ This systematic review with qualitative best evidence synthesis shows Level II evidence for the efficacy of cervical interlaminar epidural injections with local anesthetic with or without steroids, based on at least one high-quality relevant randomized control trial in each category for disc herniation, discogenic pain without facet joint pain, central spinal stenosis, and post surgery syndrome.

Case Reports
Pain relief with percutaneous trochanteroplasty in a patient with bilateral trochanteric myelomatous lytic lesions.
Multiple myeloma is a hematologic malignancy associated with destructive bone loss. Lytic lesions, a hallmark of this cancer, can result in significant morbidity because of associated pain and structural osseous compromise. Osteoplasty has demonstrated efficacy in the treatment of myelomatous pain within the axial skeleton; however, there is limited evidence supporting the utility of osteoplasty to treat extra-spinal lesions. ⋯ The intended goals of this novel procedure were to determine the cause of the suspected lytic lesions, provide pain relief, and offer structural stability by safely implanting bone cement as part of a fracture prevention strategy. At 12 month follow-up, the patient's pain improved by 70% and she no longer required the use of pain medication. The patient also displayed a significant improvement in her day-to-day functioning and quality of life.
