Multicenter Study
Long-term Results of Percutaneous Lumbar Decompression for LSS: Two-Year Outcomes.
The aim of this report was to evaluate the long-term effectiveness and safety of mild lumbar decompression for the treatment of neurogenic claudication associated with lumbar spinal stenosis. This technique uses a percutaneous dorsal approach to remove small portions of ligament and lamina, thereby restoring space and decompressing the spinal canal. ⋯ In this report of 2-year follow-up on 45 patients treated with mild percutaneous lumbar decompression, patients experienced statistically significant pain relief and improved functionality.

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.

Comparative Study
Sensory Hyperalgesia is Characteristic of Nonspecific Arm Pain: A Comparison With Cervical Radiculopathy and Pain-Free Controls.
Nonspecific arm pain (NSAP) is a common clinical entity, the pathophysiological mechanisms of which are poorly understood. The purpose of this study was to investigate sensory profiles in individuals with nonspecific arm pain compared with cervical radiculopathy and pain-free controls. ⋯ Sensory profiles in NSAP and cervical radiculopathy differ. NSAP is characterized by widespread sensitivity to thermal and pressure pain in the absence of thermal hypoaesthesia, whereas cervical radiculopathy is characterized by the presence of thermal and vibratory hypoaesthesia as well as more localized cold and pressure pain sensitivity. The identification of widespread sensory hypersensitivity in NSAP has important implications for clinical decision making.

Randomized Controlled Trial Retracted Publication
Effect of a Long-lasting Multidisciplinary Program on Disability and Fear-Avoidance Behaviors in Patients With Chronic Low Back Pain: Results of a Randomized Controlled Trial.
To evaluate the effect on disability, kinesiophobia, pain, and the quality of life of a long-lasting multidisciplinary program based on cognitive-behavioral therapy and targeted against fear-avoidance beliefs in patients with chronic low back pain. ⋯ The long-lasting multidisciplinary program was superior to the exercise program in reducing disability, fear-avoidance beliefs and pain, and enhancing the quality of life of patients with chronic low back pain. The effects were clinically tangible and lasted for at least 1 year after the intervention ended.
