Randomized Controlled Trial Comparative Study
Pregabalin Vs. Opioids for the Treatment of Neuropathic Cancer Pain: A Prospective, Head-to-Head, Randomized, Open-Label Study.
Neuropathic cancer pain (NCP) is a common manifestation of cancer and/or its treatment. Treatment following the WHO analgesic ladder provides relief for the majority of cancer pain patients; however, concern remains that opioids may be less efficacious for neuropathic pain (NP) compared with nociceptive pain, often necessitating the use of higher doses. Adjuvants, such as pregabalin, have shown to be efficacious for the treatment of NP, although data come mostly from noncancer studies. The comparative efficacy and safety of opioids versus adjuvants has not been studied for NCP. The aim of this study was to directly compare pregabalin versus a strong opioid for the treatment of NCP. ⋯ Prompt use of a neuropathic pain-specific adjuvant, such as pregabalin, in NCP may lead to better control of the neuropathic component, with opioid-sparing effects.

Chronic pain is distressing for patients and a burden on healthcare systems and society. Recent research demonstrates different aspects of the negative impact of chronic pain and the positive impact of successful treatment, making an overview of the costs and consequences of chronic pain appropriate. ⋯ Strenuous efforts should be put into obtaining good levels of pain relief for people in chronic pain, including the opportunity for multiple drug switching, using reliable, validated, and relatively easily applied patient-centered outcomes. Detailed, thoughtful and informed decision analytic policy modeling would help understand the key elements in organizational change or service reengineering to plan the optimum pain management strategy to maximize pain relief and its stream of benefits against budgetary and other constraints. This paper contains the information on which such models can be based.

Review Case Reports
Patients with a History of Spine Surgery or Spinal Injury may have a Higher Chance of Intrathecal Catheter Granuloma Formation.
Intrathecal drug delivery is an effective method to treat intractable pain. However, intrathecal catheter tip granuloma (ICTG) is a devastating complication of intrathecal drug delivery systems. It typically occurs in the thoracic region; particularly, in patients receiving high doses or high concentrations of intrathecal drug infusions. ⋯ Cerebrospinal fluid flow dynamics within the spinal canal along with the physical, chemical, and immunological properties of intrathecal medications have been suggested to be responsible for the growth of inflammatory mass lesions at the tips of intrathecal drug delivery catheters. Our literature review supports the possible role of certain factors, specifically previous spine surgery or spinal injury, in granuloma formation. The rate of development of ICTG appears to be higher in patients who have had previous spine surgery or spinal injury (68%) than in a general cohort of patients (48%), with an intrathecal pump. Therefore patients with a history of spine surgery or injury may be at increased risk of ICTG when receiving chronic intrathecal analgesia.
