Family-based Interventions Benefit Individuals With Musculoskeletal Pain in the Short-term but not in the Long-Term: A Systematic Review and Meta-Analysis
Discussion: There is moderate-quality evidence that family-based interventions result in small, significantly better pain and disability outcomes in the short-term compared with individual-focused interventions in patients with musculoskeletal pain. Based on low-quality evidence, family-based interventions result in small improvements on pain in the short-term compared with usual care. Future studies should review the content and optimize the mechanisms underpinning family-based interventions in musculoskeletal pain so that the approach could be further tested in adequately powered RCTs.

Deep Cervical Plexus Block for Neck and Shoulder Pain Due to Myofascial Pain: A Randomized Clinical Trial
Objectives: Myofascial pain is one of the most common causes of regional pain with no definitive treatment. This randomized clinical trial was conducted to assess the efficacy of deep cervical plexus block versus placebo injection (sham block) for the treatment of myofascial neck and shoulder pain in terms of analgesic consumption and pain during a follow-up period of 2 weeks after the block. Materials and Methods: Patients were randomly divided into 2 groups. Group I (block) received deep cervical plexus block and group II (placebo) received normal saline. A total of 66 patients were included in the study, 34 p...

A High Psychological and Somatic Symptom Profile and Family Health Factors Predict New or Persistent Pain During Early Adolescence
We examined whether Pain/PSS profile predicted 1-year new/persistent pain when controlled for child characteristics and intergenerational mental health factors. Results: Four profiles were differentiated: No Pain/Low PSS, No Pain/High PSS, Pain/Low PSS, Pain/High PSS. Trauma exposure and family symptoms were associated with increased odds of being in the higher PSS groups. Baseline symptom profile predicted 14% of the variance in new/persistent pain at 1-year. Compared with the No Pain/Low PSS group, an increased odds of 1-year new or persistent pain was found in children with No Pain/High PSS (adjusted odds ratio [...

The Source of Hemisensory Disturbances in Complex Regional Pain Syndrome
Objectives: In complex regional pain syndrome (CRPS), sensory deficits and/or hyperalgesia often extend beyond the affected limb to encompass other sites on the ipsilateral side of the body.

Pain in Youth With Sickle Cell Disease: A Report From the Sickle Cell Clinical Research and Intervention Program
Objectives: Pain is prevalent among youth with sickle cell disease (SCD). However, previous research has been limited by small sample sizes and lacked examinations of developmental differences in pain, which are critical to minimizing the development of chronic pain as youth transition into adulthood. The primary aim of the current study was to compare pain and pain interference across 4 developmental groups in a large sample of youth with SCD. The secondary aim was to identify risk factors for greater pain and pain interference. Materials and Methods: Utilizing a cross-sectional study design, the expression and...

A 3-way Cross-over Study of Pregabalin, Placebo, and the Histamine 3 Receptor Inverse Agonist AZD5213 in Combination With Pregabalin in Patients With Painful Diabetic Neuropathy and Good Pain-reporting Ability
In this study, patients with painful diabetic neuropathy were trained using an experimental pain paradigm in an attempt to enroll a subset of patients who are “pain connoisseurs” and therefore more able to discriminate between active and placebo treatments. Methods: AZD5213, a novel histamine H3 receptor inverse agonist+pregabalin, pregabalin, and placebo were then tested in a 3-period cross-over.

Discussion: We found a significant association between anxiety, current smoking, psychological conditions, and current opioid use with increased preoperative and postoperative reported pain score.

Reliability, Discriminative, and Prognostic Validity of the Multidimensional Symptom Index in Musculoskeletal Trauma
Discussion: The MSI holds promise as a tool for evaluating change, screening for MDD, and identifying those at high or low risk of poor recovery. The results favor sensitivity over specificity. The labile nature of the acute pain symptoms and a truncated distribution of Nonsomatic Symptoms scores in that group both require some caution in interpretation. The MSI appears to be a potentially useful tool for rapid pain phenotyping, evaluation, and quick screening purposes in clinical practice. (Source: The Clinical Journal of Pain)
