Randomized Controlled Trial Clinical Trial
Response to pulsed and continuous radiofrequency lesioning of the dorsal root ganglion and segmental nerves in patients with chronic lumbar radicular pain.
We aimed to prospectively evaluate the response and safety of pulsed and continuous radiofrequecy lesioning of the dorsal root ganglion/segmental nerves in patients with chronic lumbosacral radicular pain. ⋯ Pulsed mode radiofrequency of the dorsal root ganglion of segmental nerves appears to be a safe treatment for chronic lumbosacral radicular pain. A significant number of patients can derive at least a short-term benefit. The addition of heat via continuous radiofrequency does not offer a significant advantage. A randomized controlled trial is now required to determine the effectiveness of pulsed radiofrequency.

Review Case Reports
Clostridial sacroiliitis in a patient with fecal incontinence: a case report and review of the literature.
Image-guided sacroiliac joint injections are frequently employed for both diagnostic and therapeutic relief of low back pain. ⋯ Pyogenic sacroiliitis is rare and usually occurs in the setting of trauma, drug abuse, or extraspinal infections. Joint infections with Clostridium have been reported after traumatic events including puncture, surgery, and abrasions. Clostridium spores are resistant to chemical preparations used for skin sterilization and require high heat for destruction. Possible practice guidelines with patients that are stool incontinent include mechanical wash prior to sterile preparation and placement of an occlusive sterile dressing after injection to prevent stool contamination of the needle puncture site. As with all rare complications, large scale studies are needed to better identify risk factors to formulate practice management strategies.

Medications which bind to opioid receptors are increasingly being prescribed for the treatment of multiple and diverse chronic painful conditions. Their use for acute pain or terminal pain is well accepted. Their role in the long-term treatment of chronic noncancer pain is, however, controversial for many reasons. ⋯ Switching opioids and/or routes of administration may also provide benefits for patients. Proper patient screening, education, and preemptive treatment of potential side effects may aid in maximizing effectiveness while reducing the severity of side effects and adverse events. Opioids can be considered broad spectrum analgesic agents, affecting a wide number of organ systems and influencing a large number of body functions.

Opioids are important, if not essential, agents in treating certain types of chronic pain. However, the prevalence of drug misuse, abuse, and addiction has fostered considerable consternation among physicians, who may hesitate to prescribe these medications both due to concern for patients (misuse, abuse, and addiction), and fears of prosecution and/or professional sanction. Such practice may reflect 1) inadequate knowledge about patients' susceptibility to, or current drug misuse or abuse; 2) lack of familiarity with extant assessments and/or regulations, and/or 3) an unanticipated reaction to existing guidelines, policies or laws. ⋯ Adherence monitoring is critical to identify patients' prior and current drug use, establish treatment basis, and evaluate compliance, so as to avoid misuse and abuse, and ensure sound and proper pain management. This paper provides a review of the numerous monitoring approaches that have been described in the literature and addresses the benefits and limitations of these techniques and tools. The complex nature of the problem of drug misuse and abuse is discussed, and while no single monitoring technique can fully address this complex issue, we describe how multiple approaches to adherence monitoring may be employed to sustain the prudent use of opioids for the treatment of chronic pain.

Therapeutic opioid use and abuse coupled with the nonmedical use of other psychotherapeutic drugs has shown an explosive growth in recent years and has been a topic of great concern and controversy. Americans, constituting only 4.6% of the world's population, have been consuming 80% of the global opioid supply, and 99% of the global hydrocodone supply, as well as two-thirds of the world's illegal drugs. With the increasing therapeutic use of opioids, the supply and retail sales of opioids are mirrored by increasing abuse in patients receiving opioids, nonmedical use of other psychotherapeutic drugs (in this article the category of psychotherapeutics includes pain relievers, tranquilizers, stimulants, and sedatives, but does not include over-the-counter drugs), emergency department visits for prescription controlled drugs, exploding costs, increasing incidence of side effects, and unintentional deaths. ⋯ Therapeutic opioid use has increased substantially, specifically of Schedule II drugs. Apart from lack of effectiveness (except for short-term, acute pain) there are multiple adverse consequences including hormonal and immune system effects, abuse and addiction, tolerance, and hyperalgesia. Patients on long-term opioid use have been shown to increase the overall cost of healthcare, disability, rates of surgery, and late opioid use.
