The incidence of noncancer pain (NCP) in cancer patients is unknown. An analysis of incidence, severity, impact on quality of life (QoL), and appropriateness of NCP treatment in a cohort of cancer patients referred to a radiotherapy center is reported. ⋯ In a cancer patients' population referred to a radiotherapy center, the NCP incidence was higher than the CP incidence and NCP intensity was only slightly lower than CP. NCP was significantly pharmacologically undertreated and it was related to a decline in QoL.

Previous studies indicate that genetic variants in genes encoding proteins like matrix metalloproteinase (MMP) enzymes may affect degeneration of the intervertebral disk. One such genetic variant is a single nucleotide polymorphism insertion in the promoter region of the MMP1 gene, that is, the MMP1 rs1799750 2G allele, which increases the MMP1 expression in vitro. In this study, we examined whether the MMP1 rs1799750 2G allele might be associated with disk degeneration and clinical outcome after lumbar disk herniation. ⋯ Our findings suggest that the MMP1 rs1799750 2G/2G genotype may contribute to low back pain, sciatica, and disability after lumbar disk herniation.

Case Reports
Placement of an Intrathecal Catheter Through a Bony Fusion Mass Using 3D Image Guidance: A Case Report.
We describe the 3-dimensional (3D) image-guided placement technique for a lumbar intrathecal catheter through a dorsal fusion mass. This is the first time this technique has been reported. A patient with 6 prior spine surgeries and chronic pain syndrome presented with a challenging large dorsal fusion mass. The use of 3D cone beam computed tomography-based image guidance proved advantageous for the placement of an intrathecal drug delivery system (IDDS). ⋯ This is the first case report using 3D cone beam computed tomography-based image guidance for the placement of an intrathecal catheter through a bony fusion mass. This technique appears to be a viable option for IDDS implantation in patients with difficult anatomy.

Epidemiologic studies in the non-human immunodeficiency virus (HIV) positive population have shown greater health care utilization among persons with chronic non-cancer pain on opioid therapy. However, we are not aware of any similar data in the HIV positive population. ⋯ In our study HIV positive individuals with chronic pain were more likely to be seen in the ER and be hospitalized if they were on opioids. However, after controlling for other variables, the association with opioids no longer remained significant.

Randomized Controlled Trial
Pedometer-driven Walking for Chronic Low Back Pain: A Feasibility Randomized Controlled Trial.
To evaluate the feasibility of an RCT of a pedometer-driven walking program and education/advice to remain active compared with education/advice only for treatment of chronic low back pain (CLBP). ⋯ This preliminary study demonstrated that a main RCT is feasible. EWP was safe and produced a real increase in walking; CLBP function and pain improved, and participants perceived a greater improvement in their PA levels. These improvements require confirmation in a fully powered RCT.
