Multicenter Study Clinical Trial
A cost-consequences analysis of the effect of pregabalin in the treatment of painful radiculopathy under medical practice conditions in primary care settings.
To analyze the effect of pregabalin (PGB) on pain relief, longitudinal utilization of health and nonhealth resources and derived costs in patients with refractory painful radiculopathy under routine medical practice in primary care settings (PCS). ⋯ In PCS, either PGBadd-on or PGBm under routine medical practice was associated with pain alleviation leading to significant longitudinal reductions in resource use and total costs compared with non-PGB-therapy in subjects with painful refractory cervical or lumbar radiculopathy.

The vast majority of cancer patients experience pain, and treatment with opioids offers the most effective option for pain management. Long-lasting opioid formulations are usually used as cancer pain management strategies. This review surveys the available literature on the only available once-daily sustained-release formulation of hydromorphone, and its use in cancer pain management. ⋯ The pharmacokinetics of OROS hydromorphone are linear and dose-proportional, and only minimally affected by the presence or absence of food. In addition, the SR properties of OROS hydromorphone are maintained in the presence of alcohol, with no dose dumping of hydromorphone. This formulation shows promise as an addition to cancer pain management strategies, although further randomized, double-blind trials are needed to confirm this.

Cervical radicular pain is defined as pain perceived as arising in the arm caused by irritation of a cervical spinal nerve or its roots. Approximately 1 person in 1,000 suffers from cervical radicular pain. In the absence of a gold standard, the diagnosis is based on a combination of history, clinical examination, and (potentially) complementary examination. ⋯ When its effect is insufficient or of short duration, conventional radiofrequency treatment is recommended (2B+). In selected patients with cervical radicular pain, refractory to other treatment options, spinal cord stimulation may be considered. This treatment should be performed in specialized centers, preferentially study related.

Complex regional pain syndrome is a condition that usually affects the upper or lower extremities. The cause is not clearly understood. We report a case of a severe form of a rapidly progressive complex regional pain syndrome type I developing after a right shoulder injury managed with spinal cord stimulation (SCS). ⋯ Due to the need for frequent recharging, the system was removed. During explantation of the surgical paddle lead, it was noted by the neurosurgeon that the contacts of the paddle lead were detached from the lead. After successful implantation of another SCS system, the patient was able to reduce her medications and is now able to ambulate with the use of a left elbow crutch.

Occipital nerve stimulation is a modality reserved for refractory headache disorders. Leads (wires) are inserted subcutaneously in the occipital region to stimulate the distal C1-3 nerves; lead migration may result from repeated mechanical forces on the lead associated with patient movement. The primary aim of this study was to determine implantation pathways associated with the least pathway length change secondary to body movement in an in vitro model of an occipital stimulator system. ⋯ Internal pulse generators in sites other than the buttock, including infraclavicular or low abdomen, may be associated with lower lead migration risk. There are many considerations when selecting insertion sites and lead pathways for occipital nerve stimulation. Implanters and patients may consider these results when contemplating surgical approaches to this challenging form of peripheral nerve stimulation.
