Objectives. Post-herpetic neuralgia (PHN) is a painful complication of herpes zoster infection and a common cause of chronic severe pain in elderly and/or debilitated patients. Although a wide range of treatments have been tried, a substantial number of patients continue to experience pain which remains refractory to all therapies. Increasingly, studies have demonstrated that oral opioids can have a beneficial effect on neuropathic pain. ⋯ Patients most commonly reported improvement in the deep component of their pain, next allodynia, and less so superficial lancinating pain. Conclusions. In conclusion, while a complex therapy, long-term use of intrathecal opioids is well tolerated, doses are titratable, administration is safe, and may help relieve severe short- and long-term neuropathic pain in selected PHN patients. Whether the addition of newer investigational intrathecal agents could improve these results is yet to be determined.

Introduction. Chronic pain is a prevalent medical condition in the general population and is one of the most common reasons patients visit their primary care doctors. When the pain is resistant to the common treatment modalities, it presents a challenge for the physician and may have profound consequences for the quality of life of the patient. ⋯ The patients reported decreased use of pain medications, increased quality of life, and high satisfaction with the procedure results. Conclusion. The use of subcutaneous peripheral nerve stimulation as a viable treatment alternative in certain cases of chronic neuropathic pain should continue to be rigorously evaluated.

Objectives. We submit a retrospective analysis of results of eight patients suffering from intractable pain of established or suspected thalamic origin. These patients were treated with spinal cord stimulation (SCS) in the cervical or dorsal cord. No patient was suffering pain from a complete hemibody or facial area. ⋯ Two patients had a further stroke: One died and one was cured from pain. Good-to-excellent results were attained in six patients; long-term good-to-excellent results were maintained in three patients. Conclusions. Despite previous adverse reports, certain cases of thalamic pain can be effectively alleviated through SCS.
