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.

Observational Study
Radiologic Analysis and Clinical Study of the Upper One-third Joint Technique for Fluoroscopically Guided Sacroiliac Joint Injection.
Sacroiliac intraarticular injection by the traditional technique can be challenging to perform when the joint is covered with osteophytes or is extremely narrow. ⋯ Sacroiliac intraarticular injections with the upper one-third joint technique are advisable when it is hard to perform them with the lower one-third joint technique.

Review Meta Analysis
Is Serum Hypovitaminosis D Associated with Chronic Widespread Pain Including Fibromyalgia? A Meta-analysis of Observational Studies.
Chronic widespread pain (CWP) is a global musculoskeletal disorder leading to disability and a reduced quality of life. Low levels of serum vitamin D has long been proposed to be associated with CWP, but previous research remains inconclusive. ⋯ There was a positive crude association between hypovitaminosis D and CWP, and the association was likely to remain after adjusting confounding factors. Use of a cut-off value of hypovitaminosis D (8-10 ng/mL) could better define the population with and without CWP. Further prospective follow-up studies are warranted to clarify the causal relationship between hypovitaminosis D and CWP.
