We sometimes encounter unintentional flow of contrast into the facet joints during cervical interlaminar epidural injection, which leads to false-positive epidural injection. The purposes of this study were to evaluate the rate of facet flow of contrast and to investigate various factors associated with injection into the space of Okada during fluoroscopy-guided cervical interlaminar epidural injection. ⋯ We detected injection into the space of Okada during fluoroscopy-guided cervical interlaminar epidural injection in 6.0% of procedures. Cervical interlaminar epidural injection at C5-6 and above and the paramidline approach for epidural injection were positive predictors of unintentional facet flow of the contrast.

To conduct a systematic literature review of brain neurostimulation for pain. ⋯ Moderate evidence supports DBS to treat chronic pain. Additional Level I RCTs are needed to further the strength of the evidence in this important area of medicine, but the current evidence suggests that DBS should be considered as an option in treating complex pain cases.

A growing body of literature shows that justice-related appraisals are significant determinants of pain-related outcomes and prolonged trajectories of recovery. We conducted a systematic review of the literature assessing the relationship between perceived injustice and pain-related outcomes in individuals with musculoskeletal pain. ⋯ This systematic review summarizes the current evidence for the association between perceived injustice and pain-related outcomes. There is strong evidence that perceived injustice is associated with pain intensity, disability-related variables, and mental health outcomes. Implications and directions for future research are discussed.

Randomized Controlled Trial Multicenter Study
Long-term Safety and Tolerability of NKTR-181 in Patients with Moderate to Severe Chronic Low Back Pain or Chronic Noncancer Pain: A Phase 3 Multicenter, Open-Label, 52-Week Study (SUMMIT-08 LTS).
To evaluate the long-term safety of NKTR-181, a novel mu-opioid receptor agonist that may have reduced human abuse potential, in patients with moderate to severe chronic low back pain (CLBP) or other chronic noncancer pain (CNP). ⋯ The study results support the premise that NKTR-181 is a safe and effective option for patients with moderate to severe CLBP or CNP.

Randomized Controlled Trial Clinical Trial
An Open Trial of a Mind-Body Intervention for Young Women with Moderate to Severe Primary Dysmenorrhea.
To evaluate the feasibility, acceptability, and preliminary efficacy of a mind-body intervention for moderate to severe primary dysmenorrhea (PD). ⋯ A mind-body intervention is a promising nondrug intervention for primary dysmenorrhea, and future research should focus on testing the intervention further as part of a randomized clinical trial.
