Multicenter StudyDoes Pollen Trigger Urological Chronic Pelvic Pain Syndrome Flares? A Case-Crossover Analysis in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain Research Network.
We sought to determine whether pollen triggers urological chronic pelvic pain syndrome flares. ⋯ We found some evidence to suggest that rising pollen count may trigger flares of urological chronic pelvic pain syndrome. If confirmed in future studies, these findings may help to inform flare pathophysiology, prevention and treatment, and control over the unpredictability of flares.

Evaluation of the Arabic version of the Chronic Pain Grade scale: Psychometric properties.
To increase our understanding of chronic pain in clinical and research contexts, an assessment of its dimensions using reliable and valid self-reported pain measures is imperative. However, well-validated Arabic chronic pain assessment scales are lacking. The Chronic Pain Grade (CPG) scale has been used worldwide, yet an Arabic version of the CPG scale has not yet been validated. ⋯ This study provides evidence that the Arabic CPG scale is a reliable and valid measure of chronic pain dimensions, including pain intensity, and pain-related disability. This Arabic version of the CPG scale has the potential to expand research and clinical assessment in the Arab world. Future studies are required for further validation.

Percutaneous Peripheral Nerve Stimulation of the Medial Branch Nerves for the Treatment of Chronic Axial Back Pain in Patients After Radiofrequency Ablation.
Lumbar radiofrequency ablation is a commonly used intervention for chronic back pain. However, the pain typically returns, and though retreatment may be successful, the procedure involves destruction of the medial branch nerves, which denervates the multifidus. Repeated procedures typically have diminishing returns, which can lead to opioid use, surgery, or implantation of permanent neuromodulation systems. The objective of this report is to demonstrate the potential use of percutaneous peripheral nerve stimulation (PNS) as a minimally invasive, nondestructive, motor-sparing alternative to repeat radiofrequency ablation and more invasive surgical procedures. ⋯ Percutaneous PNS has the potential to shift the pain management paradigm by providing an effective, nondestructive, motor-sparing neuromodulation treatment.

Multicenter Study Observational StudyA novel fast-acting sub-perception spinal cord stimulation therapy enables rapid onset of analgesia in patients with chronic pain.
Background: Treating chronic pain using sub-perception Spinal Cord Stimulation (SCS) does not elicit paresthesia but is associated with long analgesic 'wash-in' (i.e. duration until maximum pain relief) and prolonged assessment of therapy. We describe the attainment of clinically meaningful and rapid-onset analgesic outcomes using a novel sub-perception SCS approach. Methods: This observational case-series evaluated patients implanted with an SCS device for chronic pain, who underwent re-programming utilizing a new methodology in which paresthesia was used to guide sub-perception stimulation field targeting at specific parameters including charge-balanced symmetrical pulses at 90 Hz (termed Fast-Acting Sub-Perception Therapy, FAST). ⋯ At last follow up (mean = 223 ± 132 days), a pain score of 1.6 ± 0.3, n = 30 was determined. Conclusions: After FAST implementation, a profound analgesic response, requiring substantially less energy than conventional sub-perception methodologies, was observed. This rapid analgesic onset achieved with the novel FAST technique suggests the potential for an alternative mechanism of action(s) of sub-perception SCS.

Multicenter Study Observational StudySatisfaction with life following mild traumatic brain injury: A TRACK-TBI Study.
Identifying the principal determinants of life satisfaction following mild TBI (mTBI) may inform efforts to improve subjective well-being in this population. We examined life satisfaction among participants in the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) study who presented with mTBI (Glasgow Coma Scale [GCS] score = 13-15; n = 1152). An L1-regularization path algorithm was used to select optimal sets of baseline and concurrent symptom measures for prediction of scores on the Satisfaction with Life Scale (SWLS) at 2 weeks and 3, 6, and 12 months post-injury. ⋯ Other post-TBI symptom domains and baseline socio-demographic, injury-related, and clinical characteristics did not emerge as robust predictors of SWLS scores during the year after mTBI. Efforts to improve satisfaction with life following mTBI may benefit from a focus on the detection and treatment of affective symptoms, pain, and insomnia. The results reinforce the need for tailoring of evidence-based treatments for these conditions to maximize efficacy in patients with mTBI.
