Neoplastic brachial plexopathy (NBP) is caused by a cancerous infiltration into the brachial plexus, presenting often as severe pain in the affected upper extremity. Such pain can be resistant to medical treatment. Invasive interventions such as brachial plexus neurolysis with phenol or cordotomy may result in severe complications including permanent neurological damage and death. ⋯ Our case series suggests that, in the appropriately selected patient, this technique can safely and effectively alleviate pain from NBP. The procedure is simple, spares limb function, and can be diagnostic, predicting response to more complex procedures. To the best of our knowledge, this is the first report using this technique for NBP.

Review Meta Analysis
The Association of rs4753426 Polymorphism in the Melatonin Receptor 1B (MTNR1B) Gene and Susceptibility to Adolescent Idiopathic Scoliosis: A Systematic Review and Meta-analysis.
Adolescent idiopathic scoliosis (AIS) is a tridimensional structural deformity of the spine that may deteriorate progressively, leading to significant functional limitations and pain problems. Several previous studies have implicated the rs4753426 single nucleotide polymorphism in the melatonin receptor 1B (MTNR1B) gene in the etiology of AIS. However the sample sizes were limited and the findings of those studies were inconsistent. An overall assessment of the evidence supporting this association has not been previously conducted. ⋯ To our knowledge, there has been no meta-analysis to analyze the association between rs4753426 polymorphism in the MTNR1B gene and AIS. This systematic review was a comprehensive analysis of the currently available evidence, and found an overall significant association of rs4753426 polymorphism with the risk of AIS, especially in the Asian population. Further investigation of this association is necessary in other populations.

Randomized Controlled Trial
Effect of Individually Tailored Biopsychosocial Workplace Interventions on Chronic Musculoskeletal Pain and Stress Among Laboratory Technicians: Randomized Controlled Trial.
Chronic musculoskeletal pain is prevalent among laboratory technicians and work-related stress may aggravate the problem. ⋯ We observed significant reductions in chronic musculoskeletal pain following a 10-week individually adjusted multifaceted intervention with physical training emphasizing dynamic joint mobility and mindfulness coupled with fear-avoidance and de-catastrophizing behavioral therapy compared to a reference group encouraged to follow on-going company health initiatives. A higher dose of physical-cognitive training appears to facilitate pain reduction, whereas a higher dose of mindfulness appears to increase pain. Hence, combining physical training with mindfulness may not be an optimal strategy for pain reduction.

The sacroiliac joint is well known as a cause of low back and lower extremity pain. Prevalence estimates are 10% to 25% in patients with persistent axial low back pain without disc herniation, discogenic pain, or radiculitis based on multiple diagnostic studies and systematic reviews. However, at present there are no definitive management options for treating sacroiliac joint pain. ⋯ The evidence for the accuracy of diagnostic and therapeutic effectiveness of sacroiliac joint interventions varied from Level II to Level IV.

There is no truly optimal treatment to cure refractory neuralgia of the infraorbital nerve. Recently, nondestructive pulsed radiofrequency (PRF) has become one of the most attractive interventional techniques for painful disorders. However, use of the technique for infraorbital neuralgia has been seldom reported. ⋯ Results demonstrated PRF treatment under computed tomography (CT) guidance for infraorbital neuralgia is safe, effective, and is expected to become an alternative for patients experiencing ineffective conservative therapy. Increasing the output voltage of PRF could be the chosen method to improve the efficacy.
