Randomized Controlled Trial Comparative Study
Does random urine drug testing reduce illicit drug use in chronic pain patients receiving opioids?
Prescription drug abuse and illicit drug use are common in chronic pain patients. Adherence monitoring with screening tests, and urine drug testing, periodic monitoring with prescription monitoring programs, has become a common practice in recent years. Random drug testing for appropriate use of opioids and use of illicit drugs is often used in pain management practices. Thus, it is expected that random urine drug testing will deter use of illicit drugs, and also improve compliance. ⋯ The prevalence of illicit drug abuse in patients with chronic pain receiving opioids continues to be a common occurence. This study showed significant reductions in overall illicit drug use with adherence monitoring combined with random urine drug testing.

Comparative Study
A novel approach to transnasal sphenopalatine ganglion injection.
Sphenopalatine ganglion block is used to treat headache and facial pain. There are transnasal, transoral and lateral approaches to establish the blockade. The transnasal application of topical anesthetic is the simplest and most common technique among the three. However, the diffusion of topical anesthetic to the ganglion is unpredictable and the blockade is not durable. ⋯ This method preserves the technical simplicity of the original transnasal approach and includes the predictability and durability of the blockade from needle injection.

Comparative Study Controlled Clinical Trial
Treatment of painful advanced internal lumbar disc derangement with intradiscal injection of hypertonic dextrose.
Degenerative discs are thought to produce nerve root pain either mechanically or chemically. Particularly in the case of advanced degenerative disc disease, this clinical entity has often proven to be symptomatically resistant to peridural steroids, Intra-discal Electrothermoplasty (IDET) and direct surgical intervention. Exposure of irritated nerves to hypertonic dextrose is thought to have chemoneuromodulatory potential. Sustained pain reduction has been demonstrated in a pilot study involving injection of a combination of dextrose, glucosamine, chondroitin and dimethylsulfoxide into degenerative discs of patients with chronic low back pain of discogenic origin. ⋯ The results suggest that intradiscal injection of hypertonic dextrose may have a place in the management of pain arising from advanced lumbar degenerative disc disease.

Comparative Study Controlled Clinical Trial
Quality assurance for interventional pain management procedures.
Over the last decade various guidelines for quality assurance in pain medicine have been published for cancer pain, acute postoperative pain and other pain conditions. However, quality assurance for interventional pain management procedures has yet to be addressed. An interventional pain program should at least evaluate 1) efficacy of pain relief; 2) complication rate; and 3) patient satisfaction. ⋯ The results of the current study indicate that quality assurance of interventional pain management procedures in terms of immediate pain relief following the procedure, low complication rate, and high patient satisfaction can be achieved through application of a quality assurance program.

Clinical studies have demonstrated the efficacy of pulsed radiofrequency (PRF). PRF energy is delivered to neural structures via specifically designed, percutaneously placed needles to treat some chronic pain states. PRF was introduced as a non-destructive alternative to destructive lesioning produced by continuous radiofrequency (CRF) energy. However, there is an ongoing controversy regarding the potential tissue-destructive effects of PRF used for pain management. ⋯ PRF coagulated egg white at temperatures above 60degrees C in a manner similar to CRF. Monitoring needle tip temperature using the thermode supplied with the needle during PRF and keeping the recorded tip temperature below 60degrees C may minimize unwanted thermal destruction of tissue.
