The objective of this article is to critically review both preclinical and clinical studies that focus on the use of nanotechnology for both acute and chronic pain management, surveying both diagnostic and therapeutic applications. The article also provides information on nanotechnology for pain practitioners, so that they may better understand how this technology works and how it may be applied to their day-to-day clinical practice. ⋯ As the development of nanomedical applications in acute and chronic pain management continues, medical practitioners should consider their growing potential to enhance the care of patients who are consistently living with pain. Current barriers to implementation include manufacturing scale-up for commercial viability, long-term nanoparticle toxicity considerations, and high cost for successful passage through clinical trials. These challenges will need to be overcome with ongoing translational research efforts in collaboration with industry and government bodies such as the Food and Drug Administration (FDA).

This project was designed to test the feasibility and effectiveness of acupuncture therapy given in a group setting for chronic pain. ⋯ Acupuncture therapy offered in the group setting was effective in reducing pain severity, pain interference, and depression in patients with chronic neck, back, or shoulder pain or osteoarthritis. Benefit persisted through the 24-week measure despite no additional treatment. This finding has potentially important implications for improving access to effective acupuncture treatment for patients with limited financial resources.

Observational Study
Does Immediate Pain Relief After an Injection into the Sacroiliac Joint with Anesthetic and Corticosteroid Predict Subsequent Pain Relief?
To determine if immediate pain response following an injection with local anesthetic and corticosteroid predicts subsequent relief. ⋯ Patients who fail to achieve initial relief after SIJ injection with anesthetic and steroid are very unlikely to achieve significant pain relief at follow-up; negative likelihood ratios (LR) in this study, based on how success is defined, range between 0 and 0.9. Clinically significant positive likelihood ratios of anesthetic response to SIJ injection are more limited and less robust, but are valuable in predicting 50% relief or 100% relief at two to four weeks.

To determine the attitudes of patients toward long-term opioid therapy (LtOT) and the potential risk of misuse/abuse in patients with chronic noncancer pain (CNCP). ⋯ Despite public opinion, patients treated with LtOT for CNCP and followed in a tertiary care pain center are at low risk for opioid misuse/abuse. We need to refine the way of prescribing opioids, should be selective with our patients, and should relive their pain adequately.

The authors investigated a wide range of perioperative outcome measures in the context of a robust regional anesthesia practice. ⋯ A regional anesthesia-based practice in ambulatory surgery is an effective means of providing excellent postoperative analgesia and is associated with a low rate of PONV and unexpected admissions. Dexamethasone, clonidine, and their combination when combined with 0.5% ropivacaine may have mixed effects on PONS risk that warrant dose/concentration alterations of these three drugs in the context of off-label perineural adjunct use.
