Randomized Controlled Trial
Prospective, Randomized Blind Effect-on-Outcome Study of Conventional vs High-Frequency Spinal Cord Stimulation in Patients with Pain and Disability Due to Failed Back Surgery Syndrome.
Spinal cord stimulation (SCS) for patients with failed back surgery syndrome (FBSS) show variable results and limited to moderate evidence. In the last years the stimulation of high frequency (HF) has been considered as a better alternative in this pathology for its supposed benefits compared to the stimulation with conventional frequency (CF). To compare in one year follow-up, the efficacy of high-frequency SCS (HF) versus conventional frequency SCS (CF) on the patients with FBSS. ⋯ The evolutionary pattern of the different parameters studied in our patients with FBSS does not differ according to their treatment by spinal stimulation, with conventional or high frequency, in one year follow-up.

Not only is persistent pain a debilitating health problem for older adults, it also may have negative effects on family relationships. Studies have documented the effects of pain on spouses and on parents of young children. However, research has not extended this line of inquiry to later life, and specifically to the impact of older parents' pain symptoms on adult children. This study addresses the question: Does older mothers' pain affect the quality of relations with offspring? ⋯ Based on the findings of this article, further exploration of the impact of chronic pain on relations between adult children and their parents is justified. Of interest is exploration of factors that may insulate later-life intergenerational relationships from the effects of pain.

Previous studies suggest that trigger points (TrPs) contribute to migraine pain, but no data is available on the effects of TrPs on pressure pain sensitivity. Our objective was to investigate the association between the number of TrPs and widespread pressure hypersensitivity in women with episodic migraines. ⋯ This study found that the number of active but not latent TrPs in head and neck and shoulder muscles was associated with widespread pressure hypersensitivity in women with episodic migraines, suggesting a potential contribution of active TrPs as contributors for sensitization processes in migraines.

Intrathecal drug delivery systems (IDDSs) have dramatically improved analgesia and the functional status of cancer patients and those with chronic pain states. However, given the close proximity to the neuraxis and frequent concomitant use of antiplatelet or anticoagulant medications, this intervention is not without risk. The goal of this investigation was to determine the incidence of bleeding complications following IDDS placement. ⋯ No cases of bleeding-related neurological complications were identified following IDDS placement or revision, including in those receiving aspirin or NSAIDs. Future investigations with larger numbers are needed to further explore the safety of antithrombotic therapy continuation or discontinuation periprocedurally.
