Comparative Study Controlled Clinical Trial
Evaluation of therapeutic thoracic medial branch block effectiveness in chronic thoracic pain: a prospective outcome study with minimum 1-year follow up.
The prevalence of persistent upper back and mid back pain due to involvement of thoracic facet joints has been described in controlled studies as varying from 43% to 48% based on IASP criteria. Therapeutic intraventions utilized in managing chronic neck pain and low back pain of facet joint origin include intraarticular injections, medial branch nerve blocks, and neurolysis of medial branch nerves by means of radiofrequency. These interventions have not been evaluated in managing chronic thoracic pain of facet joint origin. ⋯ Therapeutic thoracic medial branch blocks were an effective modality of treatment in managing chronic thoracic pain secondary to facet joint involvement confirmed by controlled, comparative local anesthetic blocks.

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.

Case Reports Comparative Study
Treatment challenges and complications with ziconotide monotherapy in established pump patients.
The U.S. Food and Drug Administration (FDA) recently approved Ziconotide intrathecal infusion for the management of severe chronic pain in patients for whom intrathecal therapy is warranted, and who are intolerant of, or refractory to, other methods of treatment, including intrathecal morphine. Ziconotide is approved as a monotherapy, but there are challenges associated with the decision to wean intrathecal opioids for Ziconotide alone. Maintaining adequate analgesia and managing opioid withdrawal symptoms may be difficult. Additionally, a variety of adverse physiological, cognitive and psychiatric events may be associated with this new drug. Patients with pretreatment psychiatric disorders may be at increased risk for treatment complications. ⋯ This report describes challenges associated with the decision to convert established pump patients from intrathecal opioid therapy to Ziconotide monotherapy. Inadequate analgesia, adverse medication effects, and opioid withdrawal symptoms can precipitate a stressful situation that may be perceived as dangerous or threatening by patients who are predisposed to anxiety. Screening patients for psychiatric disorders, anxiety-proneness and/or vulnerability to stress should be considered to reduce the risk of treatment complications. A multimodal approach is strongly advocated, including rapid responses of treating physicians and nurses along with strong psychological support.

Case Reports Comparative Study
Pulsed radiofrequency of lumbar nerve roots for treatment of chronic inguinal herniorraphy pain.
Inguinal hernia repairs are commonly performed and although not seen in a majority of patients, chronic inguinal pain can be a debilitating state resulting after inguinal hernia repairs. Treatment options exist, including pharmacological and surgical management, but with associated risks and side effects. ⋯ The mechanism of action of pulsed radiofrequency remains unclear. This case study demonstrates the effectiveness of minimally invasive neurodestruction of T12, L1 and L2 nerve roots utilizing Pulse Radiofrequency fields.
