Case Reports
Thoracic spinal cord stimulation for neuropathic pain after spinal meningioma removal: a case report.
Spinal cord stimulation (SCS) is highly successful for treating neuropathic pain but its effect is limited for central origin pain caused by cord injury. The authors describe a case in which pain was successfully controlled by SCS implantation in a patient with intractable chronic neuropathic pain after T5 meningioma removal. The authors tried lead insertion over the T5 level passing through postoperative adhesions to produce adequate stimulation to the patient's painful areas fully enough without any complications. This case showed good response to SCS even though it was a central type of neuropathic pain by spinal cord injury.

The aim of the study was to evaluate whether or not there exists nociceptive and non-nociceptive hypersensitivity at latent myofascial trigger points (MTrPs). ⋯ These results confirm the existence of nociceptive hypersensitivity at latent MTrPs and provide the first evidence that there exists non-nociceptive hypersensitivity (allodynia) at latent MTrPs. Finally, the occurrence of referred muscle pain is associated with higher pain sensitivity at latent MTrPs.

Randomized Controlled Trial
8% Lidocaine pump spray relieves pain associated with peripheral blood flow disorders.
It is often difficult to reduce pain associated with peripheral blood flow disorders (PBFD) using standard analgesics. We assessed the analgesic effects of a metered-dose 8% lidocaine in patients with PBFD. ⋯ A metered-dose 8% lidocaine pump spray produced prompt analgesia in patients with PBFD-related pain without severe side effects.

Randomized Controlled Trial
Adjuvant therapy with intrathecal clonidine improves postoperative pain in patients undergoing coronary artery bypass graft.
Alpha2 adrenergic agonists have long been employed as analgesics and to sedate patients undergoing surgical procedures. In addition, their therapeutic response synergizes that elicited by opioids. Although this response is well known, the role of alpha2 agonists, such as clonidine, during various painful surgical procedures remains to be elucidated. The goal of our study was to evaluate the effects of the intrathecal administration of clonidine on postoperative pain control and time to extubation in patients undergoing coronary artery bypass grafting. ⋯ Addition of clonidine to neuraxial opioids improves the quality of analgesia postoperatively and expedites the process of weaning from mechanical ventilation. There were no serious adverse events in the cohort of the patients studied. However, the safety profile of this medication remains to be examined with a larger group of patients.

To evaluate the psychometric properties of 4 measures of acute pain in youth with sickle cell disease (SCD) during a medical procedure. ⋯ Criterion and convergent validity were demonstrated for child-report, parent-report, and observable pain behaviors. These measures seem to tap into distinct, yet overlapping aspects of the pain experience. Assessment of acute procedural pain responses in SCD requires evaluation of preprocedural pain due to the frequent presence of low-level, baseline pain.
