Radiofrequency therapy (RFT) generates molecular motion and produces heat and electromagnetic effects on tissues, which attenuate pain sensation and thereby relieve pain. This study was to observe the altering trend of physiological parameters after RFT for chronic cervical or lumbar pain. ⋯ This study showed significant efficacy of RFT in patients with chronic cervical or lumbar pain. The changes of HRV and PPG parameters may explain part of the mechanisms of RFT.

The occurrence of bone metastases is common in patients with advanced cancer. The literature supports percutaneous vertebroplasty and kyphoplasty as minimally invasive procedures to relieve pain and improve quality of life for selected patients with disabling pain from pathological vertebral fractures secondary to bone metastases. ⋯ This case and recent literature demonstrate positive outcomes of sacroplasty in terms of pain reduction and improved mobility. Further research is warranted to establish the role of such minimally invasive percutaneous procedures for pain management in cancer patients.

Multicenter Study
Safety and Efficacy of a Pharmacist-Managed Patient-Controlled Analgesia Service in Postsurgical Patients.
To compare the safety and efficacy of a pharmacist-managed patient-controlled analgesia (PCA) service with physician/midlevel provider-managed (standard) PCA services in postsurgical patients. ⋯ A pharmacist-managed PCA service provided no difference in pain control compared to standard management. The requirement for breakthrough analgesia was decreased in the pharmacist group, while the need for antiemetic use was increased. Further research should be conducted to evaluate different PCA management strategies.

Observational Study
Microbiological Evaluation of the Extension Wire and Percutaneous Epidural Lead Anchor Site Following a "2-Stage Cut-Down" Spinal Cord Stimulator Procedure.
There are concerns regarding bacterial colonization of the temporary extension leads and subsequent infection risk using the 2-stage cut-down approach in spinal cord stimulation (SCS). We sought to quantify the extent of bacterial colonization of the temporary extension wire and percutaneous epidural lead anchor site. ⋯ Despite the high colonization rate of the temporary extension wire, there were no surgical site infections. We conclude that provided appropriate strategies for the management of surgical site infections are implemented, the 2-stage cut-down procedure is a safe approach that is not associated with a higher incidence of infection.

Case Reports
A Computed Tomography-Guided Demonstration of the Unilateral Distribution of Low-Volume Epidural Injectate.
The primary objective of this case report was to demonstrate the unilateral distribution of the low volume injectate given in the epidural space when paramedian interlaminar approach is utilized under computed tomography guidance. ⋯ There was primarily unilateral distribution of low-volume injectate in the epidural space when paramedian interlaminar approach is utilized.
