In the past few decades, opioid use for the treatment of chronic noncancer pain has slowly gained acceptance. With this increase in prescription opioid use, there has also been an increase in prescription opioid abuse. To help detect aberrant drug related behaviors, clinicians have utilized urine drug screens to determine patient noncompliance in outpatient pain clinics. ⋯ The most common aberrancy detected was an abnormal urine drug screen, often with the presence of illegal substances. However, in the great majority of aberrancies detected, providers chose to continue prescribing opioids. We speculate on the reasons for this, and discuss the role of the urine drug screen in influencing prescriber behaviors.

Case Reports
Opioid abuse in cancer pain: report of two cases and presentation of an algorithm of multidisciplinary care.
The growing awareness of opioid abuse and addiction in the chronic pain population, along with increasing cancer survivorship, has heightened our awareness of this potential problem in the cancer patient. An increasing number of patients who abuse opioids have been identified in our clinical setting. ⋯ We have become increasingly aware of the problem of opioid abuse in the cancer pain population. With an approach to using safe prescribing principles adapted from chronic pain literature, and an ethically based multidisciplinary approach, clinicians can continue to treat pain successfully in the opioid-misusing cancer patient. We outline our approach in this article.

Up to 90% of patients with metastatic or advanced stage cancer will experience significant cancer-related pain. Approximately half or more of patients diagnosed with cancer may experience bone pain. It has been estimated that tumor metastases to the skeleton affect roughly 400,000 United States citizens annually. ⋯ Although the mechanisms underlying the development of bone metastases are not completely understood, there appears to be important bi-directional interactions between the tumor and the bone microenvironment. A greater understanding of the pathophysiology of painful osseous metastases may lead to better and more selective targeted analgesic therapy. Additionally, potential future therapeutic approaches to painful osseous metastases may revolutionize approaches to analgesia for this condition, leading to optimal outcomes with maximal pain relief and minimal adverse effects.

Chronic lumbosacral radicular pain is a common source of radiating leg pain seen in pain management patients. These patients are frequently managed conservatively with multiple modalities including medications, physical therapy, and epidural steroid injections. Radiofrequency has been used to treat chronic radicular pain for over 30 years; however, there is a paucity of literature about the safety and efficacy of repeat radiofrequency lesioning. ⋯ Repeated pulsed and continuous radiofrequency ablation of the lumbar dorsal root ganglion/segmental nerve shows promise to be a safe and effective long-term palliative management for lumbosacral radicular pain in some patients.

Randomized Controlled Trial
The dosages of corticosteroid in transforaminal epidural steroid injections for lumbar radicular pain due to a herniated disc.
Intervertebral disc herniations are the most common cause of lumbosacral radiculopathy, and transforaminal epidural steroid injection (TFESI) is an important tool in treating lumbosacral radiculopathy. But the ideal dose of corticosteroid in the epidural management of lumbosacral radiculopathy has yet to be determined. ⋯ We recommend a minimal effective dose of corticosteroid (triamcinolone 10 mg) in TFESI for patients with lumbosacral radiculopathy.
