Peripheral nerve stimulation is a neuromodulation modality that is increasing used to treat chronic pain. The permanent peripheral nerve stimulator systems, while easy to place are designed to stay in place and scar at the implantation site. There is a paucity of literature on explantation techniques for peripheral nerve stimulators. ⋯ There are many situations which might require a permanent peripheral nerve stimulator to be explanted such as infection, lead erosion, patient request or need for patient to undergo magnetic resonance imaging (MRI). In these scenarios, we propose a novel needle infiltration assisted technique of explantation that is safe, effective and easy to replicate.

There is a close association between diet and abdominal pain, however, relationship between inflammatory diet and characteristics of abdominal pain has not been characterized yet. ⋯ Following a pro-inflammatory diet is linked to a higher likelihood of experiencing abdominal pain, as well as increased severity and frequency of such pain. Therefore, further longitudinal studies are necessary to investigate this relationship.

Chronic hip pain is one of the most common and difficult-to-treat causes of disability. Our study's primary aim was to investigate the effects of ultrasound and fluoroscopy-guided radiofrequency thermocoagulation of the femoral and obturator nerve articular branches on chronic hip pain, and the secondary aim was to determine its effects on hip function and quality of life. ⋯ We concluded that radiofrequency thermocoagulation application to the articular branches of the femoral and obturator nerves provides pain relief, hip function improvement, and better quality of life (better physical component scores but no improvement in mental component scores in SF-12) for up to 6 months in chronic hip pain.

To investigate the predictive value of thoracic sympathetic ganglion block (TSGB) in response to ketamine infusion therapy (KIT) and spinal-cord stimulation (SCS) in patients with chronic upper-extremity pain including complex regional pain syndrome (CRPS). ⋯ A positive response to TSGB is a potential predictor for positive KIT and SCS outcomes among patients with chronic upper-extremity pain, including CRPS.

Given the high prevalence of chronic shoulder pain and encouraging early results of terminal sensory articular branch (TSAB) radiofrequency ablation to treat shoulder pain, research is warranted to refine the procedural technique based on updated neuroanatomical knowledge with the goal of further improving patient outcomes. ⋯ Based on neuroanatomical dissections of the shoulder joint, the proposed RFA protocol will provide a safe means of more complete sensory denervation and potentially improve clinical outcomes compared to historical descriptions, which must be confirmed in prospective studies.
